    Recent literature on systematic conservation planning has focused strongly on economics. It is a necessary component of efficient conservation planning because the question is about effective resource allocation. Nevertheless, there is an increasing tendency toward economic factors overriding biological considerations. Focusing too narrowly on economic cost may lead us back toward solutions resembling those obtained by opportunistic choice of areas, the avoidance of which was the motivation for development of systematic approaches. Moreover, there are many overlooked difficulties in incorporating economic considerations reliably into conservation planning because available economic data and the free market are complex. For instance, economies based on free markets tend to be shortsighted, whereas biodiversity conservation aims far into the future. Although economic data are necessary, they should not be relied on too heavily or considered separately from other sociopolitical factors. We suggest focusing on development of more-comprehensive ecological-economic modeling, while not forgetting the importance of purely biological analyses that are needed as a point of reference for evaluating conservation outcomes. © 2010 Society for Conservation Biology.

    2015-01-01

    The integration of wind and solar generators into power systems causes “integration costs” – for grids, balancing services, more flexible operation of thermal plants, and reduced utilization of the capital stock embodied in infrastructure, among other things. This paper proposes a framework to analyze and quantify these costs. We propose a definition of integration costs based on the marginal economic value of electricity, or market value – as such a definition can be more easily used in econ...

  4. From Physical Process to Economic Cost - Integrated Approaches of Landslide Risk Assessment

    Science.gov (United States)

    Klose, M.; Damm, B.

    2014-12-01

    The nature of landslides is complex in many respects, with landslide hazard and impact being dependent on a variety of factors. This obviously requires an integrated assessment for fundamental understanding of landslide risk. Integrated risk assessment, according to the approach presented in this contribution, implies combining prediction of future landslide occurrence with analysis of landslide impact in the past. A critical step for assessing landslide risk in integrated perspective is to analyze what types of landslide damage affected people and property in which way and how people contributed and responded to these damage types. In integrated risk assessment, the focus is on systematic identification and monetization of landslide damage, and analytical tools that allow deriving economic costs from physical landslide processes are at the heart of this approach. The broad spectrum of landslide types and process mechanisms as well as nonlinearity between landslide magnitude, damage intensity, and direct costs are some main factors explaining recent challenges in risk assessment. The two prevailing approaches for assessing the impact of landslides in economic terms are cost survey (ex-post) and risk analysis (ex-ante). Both approaches are able to complement each other, but yet a combination of them has not been realized so far. It is common practice today to derive landslide risk without considering landslide process-based cause-effect relationships, since integrated concepts or new modeling tools expanding conventional methods are still widely missing. The approach introduced in this contribution is based on a systematic framework that combines cost survey and GIS-based tools for hazard or cost modeling with methods to assess interactions between land use practices and landslides in historical perspective. Fundamental understanding of landslide risk also requires knowledge about the economic and fiscal relevance of landslide losses, wherefore analysis of their

    Nisan, S.

    2007-01-01

    Seawater desalination is now widely accepted as an attractive alternative source of freshwater for domestic and industrial uses. Despite the considerable progress made in the relevant technologies desalination, however, remains an energy intensive process in which the energy cost is the paramount factor. Many papers have already been published on desalination economics but a comprehensive study, based on the exhaustive analysis of a combination of energy sources and desalination processes, using state of the art economic models and realistic assumptions, is still quite rare. The aim of this paper is to fulfil this gap with a view to provide clear choices of techno-economic options to decision makers in a wide range of countries be they from the developed regions or emerging countries

  8. Integrating and rationalizing public healthcare services as a source of cost containment in times of economic crises.

    2016-02-24

    Serious concern has been raised about the sustainability of public health care systems of European Nations and ultimately about the health of European citizens, as a result of the economic crisis that has distressed Europe since 2008. The severe economic crisis of the Euro zone, which is still afflicting Europe in 2016, has in fact threatened to equally impact public health services of nations presenting either a weak or a strong domestic growth. On behalf of the European Paediatric Association, the Union of National European Societies and Associations, the authors of the Commentary debates the relationship between the effects of economic instability and health, through the report on an article recently published in the Italian Journal of Pediatrics, which emphasized the importance of integrating existing public health care services, otherwise independently provided by public hospitals, and Primary Care Paediatric networks. The interconnections between the effects of economic instability and health are briefly commented, following the observation that these two factors are not yet fully understood, and that the definition of proper solutions to be applied in circumstances, where health is negatively impacted by periods of economic distress, is still open for discussion. Furthermore it is noted that the pressure to "deliver more for less" often seems to be the driving force forging the political strategic decisions in the area of pediatric healthcare, rather than social, cultural, and economic sensitivity and competences. Thus, the delivery of appropriate pediatric healthcare seems not to be related exclusively to motivations aimed to the benefit of children, but more often to other intervening factors, including economic, and political rationales. The conclusions emphasize that local European experiences suggest that positive and cost effective healthcare programs are possible, and they could serve as a model in the development of effective cross-border regional

    2005-01-01

    Economic integration lowers one form of trade costs, tariffs, and stimulates changes in other trade costs. This paper offers a model in which integration may raise or lower the important trade cost associated with insecurity. The model can help to explain the varied experience with integration and it points to the usefulness of combining enforcement policy integration with trade policy integration.

  10. Integrating intermittent energy sources in liberalized electricity markets: from technical costs to economic penalties as a result of market rules

    2003-06-01

    With the aim of preventing climatic change and ensuring the security of energy supplies, the recent European Directive on renewable energy production sources is aimed at bringing about a very substantial increase in electricity production from renewable sources in Europe by the 2010 horizon. Generally speaking, production of electricity from renewable sources will be assured by biomass and wind, and to a lesser extent by micro hydro, technologies whose characteristics are very different from the point of view of their integration into the electricity system. Their inclusion in the electricity systems will cause problems because of the intermittent nature of the production, a factor that does not enter into the paradigms of producers, system operators or regulators. The problems raised by the integration of intermittent production are technical in nature (risk of non-availability in peak periods, the need for additional reserves) and will incur adjustment costs, but the way in which the electricity markets function will impose economic penalties generally more substantial than the added technical costs. In this paper are examined in succession: (i) the additional costs raised by intermittence; (ii) the economic penalties imposed by the operating rules of de-regulated electricity markets with electricity production from renewable sources included, with particular reference to the case of the British and Nordic markets; and (iii) an analysis of the options that could limit the gap between the additional cost of intermittent production for the system and the adjustment surcharges imposed by the electricity markets, with the aim of reducing the tension between the deregulation of the electricity market and promoting the development of renewable energy sources.

    In resent years cost reduction has been a key issue in the petroleum industry. Several findings are not economically attractive at the current cost level, and for this and other reasons some of the major oil companies require the suppliers to have implemented a cost reduction programme to prequalify for projects. The present paper addresses cost reduction through system design and integration in both product development and working methods. This is to be obtained by the combination of contracts by reducing unnecessary coordination and allow re-use of proven interface designs, improve subsystem integration by ''top down'' system design, and improve communication and exchange of experience. 3 figs

  20. Using an Integrated Hydrologic-Economic Model to Develop Minimum Cost Water Supply Portfolios and Manage Supply Risk

    Science.gov (United States)

    Characklis, G. W.; Ramsey, J.

    2004-12-01

    Water scarcity has become a reality in many areas as a result of population growth, fewer available sources, and reduced tolerance for the environmental impacts of developing the new supplies that do exist. As a result, successfully managing future water supply risk will become more dependent on coordinating the use of existing resources. Toward that end, flexible supply strategies that can rapidly respond to hydrologic variability will provide communities with increasing economic advantages, particularly if the frequency of more extreme events (e.g., drought) increases due to global climate change. Markets for established commodities (e.g., oil, gas) often provide a framework for efficiently responding to changes in supply and demand. Water markets, however, have remained relatively crude, with most transactions involving permanent transfers and long regulatory processes. Recently, interest in the use of flexible short-term transfers (e.g., leases, options) has begun to motivate consideration of more sophisticated strategies for managing supply risk, strategies similar to those used in more mature markets. In this case, communities can benefit from some of the advantages that water enjoys over other commodities, in particular, the ability to accurately characterize the stochastic nature of supply and demand through hydrologic modeling. Hydrologic-economic models are developed for two different water scarce regions supporting active water markets: Edward Aquifer and Lower Rio Grande Valley. These models are used to construct portfolios of water supply transfers (e.g., permanent transfers, options, and spot leases) that minimize the cost of meeting a probabilistic reliability constraint. Real and simulated spot price distributions allow each type of transfer to be priced in a manner consistent with financial theory (e.g., Black-Scholes). Market simulations are integrated with hydrologic models such that variability in supply and demand are linked with price behavior

    2008-01-01

    Seawater desalination is now widely accepted as an attractive alternative source of freshwater for domestic and industrial uses. Despite the considerable progress made in the relevant technologies desalination, however, remains an energy intensive process in which the energy cost is the paramount factor. This Study is a first of a kind in that we have integrated the environmental costs into the power and desalination costs. The study has focused on the seawater desalination cost evaluation of the following systems. It is supposed that they will be operating in the co-generation mode (Simultaneous production of electrical power and desalted water) in 2015: Fossil fuelled based systems such as the coal and oil fired plants and the gas turbine combined cycle plant, coupled to MED, and RO; Pressurised water reactors such as the PWR-900 and the AP-600, coupled to MED, and RO; High temperature reactors such as the GT-MHR, the PBMR, coupled to MED, with the utilisation of virtually free waste-heat provided by these reactors. The study is made in real site-specific conditions of a site In Southern Europe. Sensitivity studies for different parameters such as the fossil fuel prices, interest and discount rates, power costs etc., have also been undertaken. The results obtained are then used to evaluate the financial interest of selected integrated desalination systems in terms of a detailed cash flow analysis, providing the net present values, pay back periods and the internal rate of returns. Analysis of the results shows that among the fossil fuelled systems the power and desalination costs by circulating fluidized bed coal fired plant would be the lowest with current coal prices. Those by oil fired plants would be highest. In all cases, integrated nuclear energy systems would lead to considerably lower power and water costs than the corresponding coal based systems. When external costs for different energies are internalized in power and water costs, the relative cost

    Determining the cost-effectiveness of healthcare interventions is key to the decision-making process in healthcare. Cost comparisons are used to demonstrate the economic value of treatment options, to evaluate the impact on the insurer budget, and are often used as a key criterion in treatment comparison and comparative effectiveness; however, little guidance is available to researchers for establishing the costing of clinical events and resource utilization. Different costing methods exist, and the choice of underlying assumptions appears to have a significant impact on the results of the costing analysis. This editorial describes the importance of the choice of the costing technique and it's potential impact on the relative cost of treatment options. This editorial also calls for a more efficient approach to healthcare intervention costing in order to ensure the use of consistent costing in the decision-making process.

  4. Economics of One Health: Costs and benefits of integrated West Nile virus surveillance in Emilia-Romagna.

    Giulia Paternoster

    Full Text Available Since 2013 in Emilia-Romagna, Italy, surveillance information generated in the public health and in the animal health sectors has been shared and used to guide public health interventions to mitigate the risk of West Nile virus (WNV transmission via blood transfusion. The objective of the current study was to identify and estimate the costs and benefits associated with this One Health surveillance approach, and to compare it to an approach that does not integrate animal health information in blood donations safety policy (uni-sectoral scenario. Costs of human, animal, and entomological surveillance, sharing of information, and triggered interventions were estimated. Benefits were quantified as the averted costs of potential human cases of WNV neuroinvasive disease associated to infected blood transfusion. In the 2009-2015 period, the One Health approach was estimated to represent a cost saving of €160,921 compared to the uni-sectoral scenario. Blood donation screening was the main cost for both scenarios. The One Health approach further allowed savings of €1.21 million in terms of avoided tests on blood units. Benefits of the One Health approach due to short-term costs of hospitalization and compensation for transfusion-associated disease potentially avoided, were estimated to range from €0 to €2.98 million according to the probability of developing WNV neuroinvasive disease after receiving an infected blood transfusion.

  5. The economic costs of energy

    1980-01-01

    At a recent symposium, the economic costs of nuclear power were examined in four lectures which considered; (1) The performance of different types, size and ages of nuclear power plants. (2) The comparison between coal and nuclear power costs based on the principle of net effective cash. (3) The capital requirements of a nuclear programme. (4) The comparative costs, now and in the future, of coal-fired and nuclear plants. It is concluded that uncertainties seem to get greater rather than smaller with time probably due to the high and fluctuating world inflation rates and the great uncertainty about world economic performance introduced by the politicising of world oil supplies.

  7. Negotiators who give too much: unmitigated communion, relational anxieties, and economic costs in distributive and integrative bargaining.

    Science.gov (United States)

    Amanatullah, Emily T; Morris, Michael W; Curhan, Jared R

    2008-09-01

    A series of studies found that the personality dimension of unmitigated communion (H. L. Fritz & V. S. Helgeson, 1998) leads negotiators to make concessions to avoid straining relationships. Results indicate that even within the population of successful business executives, this dimension of relational anxiety can be identified distinctly from more general relational orientations, such as agreeableness, and that it distinctly predicts accommodating tendencies in everyday conflicts. In economic games, unmitigated communion predicts giving in contexts in which the relational norm of reciprocity applies, but not in contexts tapping instrumental or altruistic motives for cooperation. In distributive negotiations, the effect of unmitigated communion in lowering a negotiator's outcome is mediated by prenegotiation anxieties about relational strain and plans to make large concessions if needed to avoid impasse (lower reservation points). In integrative negotiations, high unmitigated communion on both sides of the negotiation dyad results in relational accommodation, evidenced by decreased success in maximizing economic joint gain but increased subjective satisfaction with the relationship.

    The objective of this study was to examine the relationship of work loss associated with gastro- the relationship of work loss associated with gastro- the relationship of work loss associated with gastro-esophageal reflux disease (GERD) and peptic ulcer disease (GERD) and peptic ulcer disease (PUD) in a large population of employed individuals in the United States (US) and quantify the individuals in the United States (US) and quantify the economic impact of these diseases to the employer. A proprietary database that contained work place absence, disability and workers' compensation data in addition to prescription drug and medical claims was used to answer the objectives. Employees with a medical claim with an ICD-9 code for GERD or PUD were identified from 1 January 1997 to 31 December 2000. A cohort of controls was identified for the same time period using the method of frequency matching on age, gender, industry type, occupational status, and employment status. Work absence rates and health care costs were compared between the groups after adjusting for demo graphic, and employment differences using analysis of covariance models. There were significantly lower (p rate of adjusted all-cause absenteeism and sickness-related absenteeism were observed between the disease groups versus the controls. In particular, controls had an average of 1.2 to 1.6 days and 0.4 to 0.6 lower all-cause and sickness-related absenteeism compared to the disease groups. The incremental economic impact projected to a hypothetical employed population was estimated to be $3441 for GERD, $1374 for PUD, and $4803 for GERD + PUD per employee per year compared to employees without these diseases. Direct medical cost and work absence in employees with GERD, PUD and GERD + PUD represent a significant burden to employees and employers.

    2016-12-01

    Using a Transaction Cost Economics (TCE) approach, this paper explores which organizational forms Accountable Care Organizations (ACOs) may take. A critical question about form is the amount of vertical integration that an ACO may have, a topic central to TCE. We posit that contextual factors outside and inside an ACO will produce variable transaction costs (the non-production costs of care) such that the decision to integrate vertically will derive from a comparison of these external versus internal costs, assuming reasonably rational management abilities. External costs include those arising from environmental uncertainty and complexity, small numbers bargaining, asset specificity, frequency of exchanges, and information "impactedness." Internal costs include those arising from human resource activities including hiring and staffing, training, evaluating (i.e., disciplining, appraising, or promoting), and otherwise administering programs. At the extreme, these different costs may produce either total vertical integration or little to no vertical integration with most ACOs falling in between. This essay demonstrates how TCE can be applied to the ACO organization form issue, explains TCE, considers ACO activity from the TCE perspective, and reflects on research directions that may inform TCE and facilitate ACO development. © The Author(s) 2016.

    2015-01-01

    Highlights: • Assessment of economics and sustainability of thermochemical ethanol production. • Exploitation of excess CO 2 saving by either importing fossil energy or CO 2 trading. • Significant increase in alcohol production by replacing biomass with natural gas. • CO 2 emission trading is not cost-competitive versus import of fossil energy. • Lowest ethanol production cost for partial oxidation as reforming technology. - Abstract: In this work, two options are investigated to enhance the economics of the catalytic production of bioethanol from biomass gasification by exploiting the excess of CO 2 emission saving: (i) to import fossil energy, in the form of natural gas and electricity or (ii) to trade CO 2 emissions. To this end, an integrated life cycle and economic assessment is carried out for four process configurations, each using a different light hydrocarbon reforming technology: partial oxidation, steam methane reforming, tar reforming and autothermal reforming. The results show that for all process configurations the production of bioethanol and other alcohols significantly increases when natural gas displaces biomass, maintaining the total energy content of the feedstock. The economic advantage of the partial substitution of biomass by natural gas depends on their prices and this is explored by carrying out a sensitivity analysis, taking historical prices into account. It is also concluded that the trade of CO 2 emissions is not cost-competitive compared to the import of natural gas if the CO 2 emission price remains within historical European prices. The CO 2 emission price would have to double or even quadruple the highest CO 2 historical price for CO 2 emission trading to be a cost-competitive option

  12. Economic evaluation of integrated care: an introduction

    Directory of Open Access Journals (Sweden)

    Hindrik Vondeling

    2004-03-01

    Full Text Available Background: Integrated care has emerged in a variety of forms in industrialised countries during the past decade. It is generally assumed that these new arrangements result in increased effectiveness and quality of care, while being cost-effective or even cost-saving at the same time. However, systematic evaluation, including an evaluation of the relative costs and benefits of these arrangements, has largely been lacking. Objectives: To stimulate fruitful dialogue and debate about the need for economic evaluation in integrated care, and to outline possibilities for undertaking economic appraisal studies in this relatively new field. Theory: Key concepts, including e.g. scarcity and opportunity costs, are introduced, followed by a brief overview of the most common methods used in economic evaluation of health care programmes. Then a number of issues that seem particularly relevant for economic evaluation of integrated care arrangements are addressed in more detail, illustrated with examples from the literature. Conclusion and discussion: There is a need for well-designed economic evaluation studies of integrated care arrangements, in particular in order to support decision making on the long-term financing of these programmes. Although relatively few studies have been done to date, the field is challenging from a methodological point of view, offering analysts a wealth of opportunities. Guidance to realise these opportunities is provided by the general principles for economic evaluation, which can be tailored to the requirements of this particular field.

    Full Text Available One of the basic links of the process of globalization are economic integrations. The aim of this paper is to systematize theoretical achievements and to review the forms, effects and conditions for connecting countries motivated by economic benefits. In addition to the theoretical review of the conceptual definition of economic integration, the focus is on the levels of economic integration from the free-trade zone to the monetary and fiscal union, explaining the specificity of each of the mentioned levels. Considering that the connection between countries always raises the question of the benefits and costs of connection, the special emphasis in this paper is placed on the potential effects for free trade. Finally, the greatest contribution of this paper is the systematization and theoretical review of the theory of optimal currency area and monetary integration, which is especially significant for the European soil, taking into account the already established European Monetary Union

  14. The economics of wind and solar variability. How the variability of wind and solar power affects their marginal value, optimal deployment, and integration costs

    Energy Technology Data Exchange (ETDEWEB)

    Hirth, Lion

    2014-11-14

    Variable renewable energy sources (VRE) for electricity generation, such as wind and solar power, are subject to inherent output fluctuations. This variability has significant impacts on power system and electricity markets if VRE are deployed at large scale. While on global average, wind and solar power currently supply only a minor share of electricity, they are expected to play a much larger role in the future - such that variability will become a major issue (which it already is in some regions). This thesis contributes to the literature that assesses these impacts the ''system and market integration'' literature. This thesis aims at answering the question: What is the impact of wind and solar power variability on the economics of these technologies?

    Variable renewable energy sources (VRE) for electricity generation, such as wind and solar power, are subject to inherent output fluctuations. This variability has significant impacts on power system and electricity markets if VRE are deployed at large scale. While on global average, wind and solar power currently supply only a minor share of electricity, they are expected to play a much larger role in the future - such that variability will become a major issue (which it already is in some regions). This thesis contributes to the literature that assesses these impacts the ''system and market integration'' literature. This thesis aims at answering the question: What is the impact of wind and solar power variability on the economics of these technologies? It will be laid out that the impact can be expressed in (at least) three ways: as reduction of value, as increase of cost, or as decrease of optimal deployment. Translating between these perspectives is not trivial, as evidenced by the confusion around the concept of ''integration costs''.

    Full Text Available Chronic diseases have an increasingly negative impact on (1 population health by increasing morbidity and mortality, (2 society by increasing health inequalities and burden to informal caregivers, and (3 economy by requiring enormous financial resources and jeopardising macro-economic development (e.g. consumption, capital accumulation, labour productivity and labour supply. Integrated care is the most promising concept in redesigning care to tackle the increasing threat of chronic diseases. Several European countries have experimented with models for integrating care, most frequently in the form of disease management programmes. These models were often supported by payment schemes to provide financial incentives to health care providers for implementing integrated care. This thesis aimed to investigate these payment schemes and assess their impact, explore the variability in costs of disease management programmes, and determine the costs and effects of disease management programmes.

  2. Integrated application of river water quality modelling and cost-benefit analysis to optimize the environmental economical value based on various aquatic waste load reduction strategies

    To assure the river water quality, the Taiwan government establishes many pollution control strategies and expends huge monetary investment. Despite all these efforts, many rivers still suffer from severe pollution because of massive discharges of domestic and industrial wastewater without proper treatment. A comprehensive evaluation tool seems required to assess the suitability of water pollution control strategies. Therefore, the purpose of this study is to quantify the potential strategic benefits by applying the water quality modelling integrated with cost-benefit analysis to simulating scenarios based on regional development planning. The Erhjen Creek is selected as the study example because it is a major river in southern Taiwan, and its riverine environment impacts a great deal to the neighboring people. For strategy assessment, we established QUAL2k model of Erhjen Creek and conducted the cost-benefit analyses according the proposed strategies. In the water quality simulation, HEC-RAS was employed to calculate the hydraulic parameters and dilution impact of tidal effect in the downstream section. Daily pollution loadings were obtained from the Water Pollution Control Information System maintained by Taiwan EPA, and the wastewater delivery ratios were calculated by comparing the occurrence of pollution loadings with the monitoring data. In the cost-benefit analysis, we adopted the market valuation method, setting a period of 65 years for analysis and discount rate at 2.59%. Capital investments were the costs of design, construction, operation and maintenance for each project in Erhjen Creek catchment. In model calibration and model verification, the mean absolute percentage errors (MAPEs) were calculated to be 21.4% and 25.5%, respectively, which met the prescribed acceptable criteria of 50%. This model was applied to simulating water quality based on implementing various pollution control policies and engineering projects in the Erhjen Creek. The overall

    For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

    This study presents a methodology for the calculation of the economic costs of the production of electricity. This methodology is applied to assess electricity production cost in Poland by type of power station for the years 1995 and 2000. In addition, an overview is presented of the methods used by the OECD countries, particularly in the Netherlands. The main conclusions of the study are: 1) the real economic costs to generate electricity in Poland are about two times higher compared with the traditional book-keeping data; 2) the investment costs will become the most important cost component in the near future; and 3) there are considerables differences in production cost per kWh for the different types of power plants in Poland. 4 appendices, 14 refs

    Narrative overview. To provide clinicians with a basic understanding of economic studies, including cost-benefit, cost-effectiveness, and cost-utility analyses. As decisions regarding public health policy, insurance reimbursement, and patient care incorporate factors other than traditional outcomes such as satisfaction or symptom resolution, health economic studies are increasingly prominent in the literature. This trend will likely continue, and it is therefore important for clinicians to have a fundamental understanding of the common types of economic studies and be able to read them critically. In this brief article, the basic concepts of economic studies and the differences between cost-benefit, cost-effectiveness, and cost-utility studies are discussed. An overview of the field of health economic analysis is presented. Cost-benefit, cost-effectiveness, and cost-utility studies all integrate cost and outcome data into a decision analysis model. These different types of studies are distinguished mainly by the way in which outcomes are valued. Obtaining accurate cost data is often difficult and can limit the generalizability of a study. With a basic understanding of health economic analysis, clinicians can be informed consumers of these important studies.

    The disposition of petroleum coke remains a problem for modern high conversion refineries. Market uncertainty and the price for coke can prevent the implementation of otherwise attractive projects. The commercially proven Texaco Gasification Process remains an excellent option for clean, cost effective coke disposition as demonstrated by the new coke gasification units coming on-line and under design. Previous papers, have discussed the coke market and general economics of coke gasification. This paper updates the current market situation and economics, and provide more details on cost and performance based on recent studies for commercial plants

    2005-09-01

    The chemical nitrogen cycle is becoming better characterized in terms of fluxes and reservoirs on a variety of scales. Galloway has demonstrated that reactive nitrogen can cascade through multiple ecosystems causing environmental damage at each stage before being denitrified to N(2). We propose to construct a parallel economic nitrogen cascade (ENC) in which economic impacts of nitrogen fluxes can be estimated by the costs associated with each stage of the chemical cascade. Using economic data for the benefits of damage avoided and costs of mitigation in the Chesapeake Bay basin, we have constructed an economic nitrogen cascade for the region. Since a single ton of nitrogen can cascade through the system, the costs also cascade. Therefore evaluating the benefits of mitigating a ton of reactive nitrogen released needs to consider the damage avoided in all of the ecosystems through which that ton would cascade. The analysis reveals that it is most cost effective to remove a ton of nitrogen coming from combustion since it has the greatest impact on human health and creates cascading damage through the atmospheric, terrestrial, aquatic and coastal ecosystems. We will discuss the implications of this analysis for determining the most cost effective policy option for achieving environmental quality goals.

    2012-01-01

    Childhood disabilities entail a range of immediate and long-term economic costs that have important implications for the well-being of the child, the family, and society but that are difficult to measure. In an extensive research review, Mark Stabile and Sara Allin examine evidence about three kinds of costs-direct, out-of-pocket costs incurred as a result of the child's disability; indirect costs incurred by the family as it decides how best to cope with the disability; and long-term costs associated with the child's future economic performance. Not surprisingly, the evidence points to high direct costs for families with children with disabilities, though estimates vary considerably within these families. Out-of-pocket expenditures, particularly those for medical costs, for example, are higher among families with children with a special health care need. An important indirect cost for these families involves decisions about employment. Stabile and Allin examine several studies that, taken together, show that having a child with disabilities increases the likelihood that the mother (and less often the father) will either curtail hours of work or stop working altogether. Researchers also find that having a child with disabilities can affect a mother's own health and put substantial strains on the parents' relationship. In the longer term, disabilities also compromise a child's schooling and capacity to get and keep gainful employment as an adult, according to the studies Stabile and Allin review. Negative effects on future well-being appear to be much greater, on average, for children with mental health problems than for those with physical disabilities. Stabile and Allin calculate that the direct costs to families, indirect costs through reduced family labor supply, direct costs to disabled children as they age into the labor force, and the costs of safety net programs for children with disabilities average $30,500 a year per family with a disabled child. They note

    Full Text Available Background: Diabetes imposes a large economic burden on the individual, national healthcare systems, and countries. Objective: To determine the economic impact of diabetes mellitus on Saudi healthcare system, both now and in the future. Materials and Methods: This research study uses a prevalence-based approach that combines the demographics of the population (classified by nationality, sex and age group with and without diagnosed diabetes in 1992 and 2010. The economic impact of diabetes is estimated in this study, using secondary sources of information provided by Ministry of Health, Ministry of Finance and Central Department of Statistics and Information databases. Results: People diagnosed with diabetes, on average, have medical healthcare expenditures that are ten times higher ($3,686 vs. $380 than what expenditures would be in the absence of diabetes. Over 96% of all medical healthcare expenditures attributed to diabetes are incurred by persons of Saudi nationality, with the remaining 4% incurred by persons of non-Saudi nationality. The population age 45-60 incurs 45% of diabetes-attributed costs, with the remaining population under age 15 incurs 3.8%, age 15-44 incurs 27.5%, and age 60 and above incurs 23.8%. Conclusion: The actual national healthcare burden because of diabetes is likely to exceed the $0.87 billion estimated in this study, because it omits the indirect costs associated with diabetes, such as absenteeism, lost productivity from disease-related absenteeism, unemployment from disease-related disability, lost productivity due to early mortality by disease. The social cost of intangibles such as pain and suffering and care provided by non-paid caregivers as well as healthcare system administrative costs, cost of medications, clinician training programs, and research and infrastructure development is also omitted from this research study. Further studies are needed to confirm the present findings and to improve our

    In this study, an economic evaluation methodology of the integrated SMART desalination plant was established and the economic evaluation of SMART was performed. The plant economics was evaluated with electricity generation costs calculated using approximate estimates of SMART cost data and the result was compared with the result calculated using the SMART design data and estimated bulk materials. In addition, a series of sensitivity studies on the power generation cost was performed for the main economic parameters of SMART Power credit method was used for the economic analysis of the integrated SMART desalination plant. Power credit method is a widely used economic analysis method for the cogeneration plant when the major portion of the energy is used for the electricity generation. In the case of using SMART fot power generation only, the result shows that the electricity generation cost of SMART is higher than that of the alternative power options. However, it can be competitive with the other power options in the limited cases, especially with the gas fired combined plant. In addition, an economic analysis of the integrated SMART desalination plant coupled with MED was performed. The calculated water production cost is in the range of 0.56 approx. 0.88($/m{sup 3}) for the plant availability of 80% or higher, which is close to the study results presented by the various other countries. This indicates that SMART can be considered as a competitive choice for desalination among various alternative energy sources.

    The question of wind integration cost has received much attention in the past several years. The methodological challenges to calculating integration costs are discussed in this paper. There are other sources of integration cost unrelated to wind energy. A performance-based approach would be technology neutral, and would provide price signals for all technology types. However, it is difficult to correctly formulate such an approach. Determining what is and is not an integration cost is challenging. Another problem is the allocation of system costs to one source. Because of significant nonlinearities, this can prove to be impossible to determine in an accurate and objective way.

  2. Economic and biological costs of cardiac imaging

    Directory of Open Access Journals (Sweden)

    Picano Eugenio

    2005-05-01

    Full Text Available Abstract Medical imaging market consists of several billion tests per year worldwide. Out of these, at least one third are cardiovascular procedures. Keeping in mind that each test represents a cost, often a risk, and a diagnostic hypothesis, we can agree that every unnecessary and unjustifiable test is one test too many. Small individual costs, risks, and wastes multiplied by billions of examinations per year represent an important population, society and environmental burden. Unfortunately, the appropriateness of cardiac imaging is extra-ordinarily low and there is little awareness in patients and physicians of differential costs, radiological doses, and long term risks of different imaging modalities. For a resting cardiac imaging test, being the average cost (not charges of an echocardiogram equal to 1 (as a cost comparator, the cost of a CT is 3.1x, of a SPECT 3.27x, of a Cardiovascular Magnetic Resonance imaging 5.51x, of a PET 14.03x, and of a right and left heart catheterization 19.96x. For stress cardiac imaging, compared with the treadmill exercise test equal to 1 (as a cost comparator, the cost of stress echocardiography is 2.1x and of a stress SPECT scintigraphy is 5.7x. Biohazards and downstream long-term costs linked to radiation-induced oncogenesis should also be considered. The radiation exposure is absent in echo and magnetic resonance, and corresponds to 500 chest x rays for a sestamibi cardiac stress scan and to 1150 chest x rays for a thallium scan. The corresponding extra-risk in a lifetime of fatal cancer is 1 in 2000 exposed patients for a sestamibi stress and 1 in 1000 for a thallium scan. Increased awareness of economic, biologic, and environmental costs of cardiac imaging will hopefully lead to greater appropriateness, wisdom and prudence from both the prescriber and the practitioner. In this way, the sustainability of cardiac imaging will eventually improve.

  4. Economics of solar energy: Short term costing

    Science.gov (United States)

    Klee, H.

    The solar economics based on life cycle costs are refuted as both imaginary and irrelevant. It is argued that predicting rates of inflation and fuel escalation, expected life, maintenance costs, and legislation over the next ten to twenty years is pure guesswork. Furthermore, given the high mobility level of the U.S. population, the average consumer is skeptical of long run arguments which will pay returns only to the next owners. In the short term cost analysis, the house is sold prior to the end of the expected life of the system. The cash flow of the seller and buyer are considered. All the relevant factors, including the federal tax credit and the added value of the house because of the solar system are included.

    2012-01-01

    Dengue, endemic in Puerto Rico, reached a record high in 2010. To inform policy makers, we derived annual economic cost. We assessed direct and indirect costs of hospitalized and ambulatory dengue illness in 2010 dollars through surveillance data and interviews with 100 laboratory-confirmed dengue patients treated in 2008–2010. We corrected for underreporting by using setting-specific expansion factors. Work absenteeism because of a dengue episode exceeded the absenteeism for an episode of influenza or acute otitis media. From 2002 to 2010, the aggregate annual cost of dengue illness averaged $38.7 million, of which 70% was for adults (age 15+ years). Hospitalized patients accounted for 63% of the cost of dengue illness, and fatal cases represented an additional 17%. Households funded 48% of dengue illness cost, the government funded 24%, insurance funded 22%, and employers funded 7%. Including dengue surveillance and vector control activities, the overall annual cost of dengue was $46.45 million ($12.47 per capita). PMID:22556069

This topic is motivated by the recent rekindling of interest in fixed exchange rates which, in turn, has been due in part to disappointment in the performance of the flexible exchange rate system that has evolved over the past two decades, and in part to the increased regional economic integration that the world economy has witnessed in the past decad...

  10. Redistributive taxation, multinational enterprises, and economic integration

    Increased activity of multinational firms exposes national corporate tax bases to cross-country profit shifting, but also leads to rising profitability of the corporate sector. We incorporate these two effects of economic integration into a simple political economy model where the median voter decides on a redistributive income tax rate. In this setting economic integration may raise or lower the equilibrium tax rate, and it is more likely to raise the tax rate of a low-tax country. The impli...

  14. Cost benefit analysis of power plant database integration

    International Nuclear Information System (INIS)

    Wilber, B.E.; Cimento, A.; Stuart, R.

    1988-01-01

    A cost benefit analysis of plant wide data integration allows utility management to evaluate integration and automation benefits from an economic perspective. With this evaluation, the utility can determine both the quantitative and qualitative savings that can be expected from data integration. The cost benefit analysis is then a planning tool which helps the utility to develop a focused long term implementation strategy that will yield significant near term benefits. This paper presents a flexible cost benefit analysis methodology which is both simple to use and yields accurate, verifiable results. Included in this paper is a list of parameters to consider, a procedure for performing the cost savings analysis, and samples of this procedure when applied to a utility. A case study is presented involving a specific utility where this procedure was applied. Their uses of the cost-benefit analysis are also described

    Sepsis is associated with high mortality and treatment costs. International guidelines recommend the implementation of integrated sepsis protocols; however, the true cost and cost-effectiveness of these are unknown. To assess the cost-effectiveness of an integrated sepsis protocol, as compared with conventional care. Prospective cohort study of consecutive patients presenting with septic shock and enrolled in the institution's integrated sepsis protocol. Clinical and economic outcomes were compared with a historical control cohort. Beth Israel Deaconess Medical Center. Overall, 79 patients presenting to the emergency department with septic shock in the treatment cohort and 51 patients in the control group. An integrated sepsis treatment protocol incorporating empirical antibiotics, early goal-directed therapy, intensive insulin therapy, lung-protective ventilation, and consideration for drotrecogin alfa and steroid therapy. In-hospital treatment costs were collected using the hospital's detailed accounting system. The cost-effectiveness analysis was performed from the perspective of the healthcare system using a lifetime horizon. The primary end point for the cost-effectiveness analysis was the incremental cost per quality-adjusted life year gained. Mortality in the treatment group was 20.3% vs. 29.4% in the control group (p = .23). Implementing an integrated sepsis protocol resulted in a mean increase in cost of approximately $8,800 per patient, largely driven by increased intensive care unit length of stay. Life expectancy and quality-adjusted life years were higher in the treatment group; 0.78 and 0.54, respectively. The protocol was associated with an incremental cost of $11,274 per life-year saved and a cost of $16,309 per quality-adjusted life year gained. In patients with septic shock, an integrated sepsis protocol, although not cost-saving, appears to be cost-effective and compares very favorably to other commonly delivered acute care interventions.

    Various studies show that raising the temperature as well as storms, cold snap, raining and drought caused by climate change. And variety disasters have had a damage to mankind. The world risk report(2012, The Nature Conservancy) and UNU-EHS (the United Nations University Institute for Environment and Human Security) reported that more and more people are exposed to abnormal weather such as floods, drought, earthquakes, typhoons and hurricanes over the world. In particular, the case of Korea, we influenced by various pollutants which are occurred in Northeast Asian countries, China and Japan, due to geographical meteorological characteristics. These contaminants have had a significant impact on air quality with the pollutants generated in Korea. Recently, around the world continued their effort to reduce greenhouse gas and to improve air quality in conjunction with the national or regional development goals priority. China is also working on various efforts in accordance with the international flows to cope with climate change and air pollution. In the future, effect of climate change and air quality in Korea and Northeast Asia will be change greatly according to China's growth and mitigation policies. The purpose of this study is to minimize the damage caused by climate change on the Korean peninsula through an integrated approach taking into account the mitigation and adaptation plan. This study will suggest a climate change strategy at the national level by means of a comprehensive economic analysis of the impacts and mitigation of climate change. In order to quantify the impact and damage cost caused by climate change scenarios in a regional scale, it should be priority variables selected in accordance with impact assessment of climate change. The sectoral impact assessment was carried out on the basis of selected variables and through this, to derive the methodology how to estimate damage cost and adaptation cost. And then, the methodology was applied in Korea

  9. Hospital-physician collaboration: landscape of economic integration and impact on clinical integration.

    2008-09-01

    Hospital-physician relationships (HPRs) are an important area of academic research, given their impact on hospitals' financial success. HPRs also are at the center of several federal policy proposals such as gain sharing, bundled payments, and pay-for-performance (P4P). This article analyzes the HPRs that focus on the economic integration of hospitals and physicians and the goals that HPRs are designed to achieve. It then reviews the literature on the impact of HPRs on cost, quality, and clinical integration. The goals of the two parties in HPRs overlap only partly, and their primary aim is not reducing cost or improving quality. The evidence base for the impact of many models of economic integration is either weak or nonexistent, with only a few models of economic integration having robust effects. The relationship between economic and clinical integration also is weak and inconsistent. There are several possible reasons for this weak linkage and many barriers to further integration between hospitals and physicians. Successful HPRs may require better financial conditions for physicians, internal changes to clinical operations, application of behavioral skills to the management of HPRs, changes in how providers are paid, and systemic changes encompassing several types of integration simultaneously.

    Most of the African countries are undergoing a complex nutrition and epidemiologic transition associated with a rapid increase in the prevalence of diverse non-communicable diseases. Despite this alarming situation, the still limited and fragmented resources available in Africa impede the implementation of effective action plans to tackle the current and projected diet-disease burden. In order to address these common needs and challenges, the African Union is increasingly supporting continental approaches and strategies as reflected in the launching of the Agenda 2063 and the African regional nutrition strategy 2015-2025, among others. To assure the successful implementation of pan-African nutritional and health initiatives, cost-effective approaches considering similarities/disparities in economy, regional integration, development and nutritional aspects between countries are needed. In the absence of pre-existing models, we reviewed regional economic integration and nutritional indicators (n 13) available in international organisations databases or governmental agencies websites, for fifty-two African countries. These indicators were used to map the countries according to common languages (e.g. Arabic, English, French, Portuguese), development status (e.g. human development index), malnutrition status (e.g. obesity) and diet (e.g. staples predominantly based on either cereals or tubers). The review of the indicators showed that there exist similarities between African countries that can be exploited to benefit the continent with cross-national experiences in order to avoid duplication of efforts in the implementation of future pan-African health studies. In addition, including present and future nutrition surveillance programmes in Africa into national statistical systems might be cost-effective and sustainable in the longer term.

    Full Text Available Abstract Background Alcohol abuse results in problems on various levels in society. In terms of health, alcohol abuse is not only an important risk factor for chronic disease, but it is also related to injuries. Social harms which can be related to drinking include interpersonal problems, work problems, violent and other crimes. The scope of societal costs related to alcohol abuse in principle should be the same for both economic evaluations and cost-of-illness studies. In general, economic evaluations report a small part of all societal costs. To determine the cost- effectiveness of an intervention it is necessary that all costs and benefits are included. The purpose of this study is to describe and quantify the difference in societal costs incorporated in economic evaluations and cost-of-illness studies on alcohol abuse. Method To investigate the economic costs attributable to alcohol in cost-of-illness studies we used the results of a recent systematic review (June 2009. We performed a PubMed search to identify economic evaluations on alcohol interventions. Only economic evaluations in which two or more interventions were compared from a societal perspective were included. The proportion of health care costs and the proportion of societal costs were estimated in both type of studies. Results The proportion of healthcare costs in cost-of-illness studies was 17% and the proportion of societal costs 83%. In economic evaluations, the proportion of healthcare costs was 57%, and the proportion of societal costs was 43%. Conclusions The costs included in economic evaluations performed from a societal perspective do not correspond with those included in cost-of-illness studies. Economic evaluations on alcohol abuse underreport true societal cost of alcohol abuse. When considering implementation of alcohol abuse interventions, policy makers should take into account that economic evaluations from the societal perspective might underestimate the total

    A review was conducted by the British Columbia Energy Council to assess the economic and social impacts of the export of long-term firm electricity to the USA and the distribution of these impacts. The objectives of, and the differences between, benefit-cost and socio-economic impact analysis are discussed as they apply to potential electricity export projects. Provincial export project review requirements (project justification, environmental impacts, socio-economic impact assessment) and proposed legislative changes are first reviewed. The concepts and objectives of value added, economic rent, opportunity costs, economic (benefit-cost) analysis, and socio-economic impact analysis are explained. Employment issues including unemployed labor, employment benefits, and regional and occupational considerations are then discussed, as well as transfers to various levels of government in the form of taxes, subsidies, resource royalties, and depletion costs. 8 refs., 4 tabs

    To evaluate costs, cost-efficiency and cost-effectiveness of integration of family planning into HIV services. Integration of family planning services into HIV care and treatment clinics. A cluster-randomized trial. Twelve health facilities in Nyanza, Kenya were randomized to integrate family planning into HIV care and treatment; six health facilities were randomized to (nonintegrated) standard-of-care with separately delivered family planning and HIV services. We assessed costs, cost-efficiency (cost per additional use of more effective family planning), and cost-effectiveness (cost per pregnancy averted) associated with the first year of integration of family planning into HIV care. More effective family planning methods included oral and injectable contraceptives, subdermal implants, intrauterine device, and female and male sterilization. We collected cost data through interviews with study staff and review of financial records to determine costs of service integration. Integration of services was associated with an average marginal cost of $841 per site and $48 per female patient. Average overall and marginal costs of integration were associated with personnel costs [initial ($1003 vs. $872) and refresher ($498 vs. $330) training, mentoring ($1175 vs. $902) and supervision ($1694 vs. $1636)], with fewer resources required for other fixed ($18 vs. $0) and recurring expenses ($471 vs. $287). Integration was associated with a marginal cost of $65 for each additional use of more effective family planning and $1368 for each pregnancy averted. Integration of family planning and HIV services is feasible, inexpensive to implement, and cost-efficient in the Kenyan setting, and thus supports current Kenyan integration policy.

  1. Systematic Approach to Better Understanding Integration Costs

    Energy Technology Data Exchange (ETDEWEB)

    Stark, Gregory B. [National Renewable Energy Lab. (NREL), Golden, CO (United States)

    2015-09-01

    This research presents a systematic approach to evaluating the costs of integrating new generation and operational procedures into an existing power system, and the methodology is independent of the type of change or nature of the generation. The work was commissioned by the U.S. Department of Energy and performed by the National Renewable Energy Laboratory to investigate three integration cost-related questions: (1) How does the addition of new generation affect a system's operational costs, (2) How do generation mix and operating parameters and procedures affect costs, and (3) How does the amount of variable generation (non-dispatchable wind and solar) impact the accuracy of natural gas orders? A detailed operational analysis was performed for seven sets of experiments: variable generation, large conventional generation, generation mix, gas prices, fast-start generation, self-scheduling, and gas supply constraints. For each experiment, four components of integration costs were examined: cycling costs, non-cycling VO&M costs, fuel costs, and reserves provisioning costs. The investigation was conducted with PLEXOS production cost modeling software utilizing an updated version of the Institute of Electrical and Electronics Engineers 118-bus test system overlaid with projected operating loads from the Western Electricity Coordinating Council for the Sacramento Municipal Utility District, Puget Sound Energy, and Public Service Colorado in the year 2020. The test system was selected in consultation with an industry-based technical review committee to be a reasonable approximation of an interconnection yet small enough to allow the research team to investigate a large number of scenarios and sensitivity combinations. The research should prove useful to market designers, regulators, utilities, and others who want to better understand how system changes can affect production costs.

    Information about the economic costs of social phobia is scant. In this study, we examine the economic costs of social phobia and subthreshold social phobia. Data were derived from the Netherlands Mental Health Survey and Incidence Study (NEMESIS) which is a population-based prospective study (n=4,789). Costs related to health service uptake, patients' out-of-pocket expenses, and costs arising from production losses were calculated for the reference year 2003. The costs for people with social phobia were compared with the costs for people with no mental disorder. The annual per capita total costs of social phobia were euro 11,952 (95% CI=7,891-16,013) which is significantly higher than the total costs for people with no mental disorder, euro 2957 (95% CI=2690-3224). When adjusting for mental and somatic co-morbidity, the costs decreased to euro 6,100 (95% CI=2681-9519), or 136 million euro per year per 1 million inhabitants, which was still significantly higher than the costs for people with no mental disorder. The costs of subthreshold social phobia were also significantly higher than the costs for people without any mental disorder, at euro 4,687 (95% CI=2557-6816). The costs presented here are conservative lower estimates because we only included costs related to mental health services. The economic costs associated with social phobia are substantial, and those of subthreshold social phobia approach those of the full-blown disorder.

    2012-01-01

    Increases in NASA mission costs have led to analysis of the causes and magnitude of historical mission overruns as well as mitigation and prevention attempts. This paper hypothesizes that one cause is that the availability of reserves may reduce incentives to control costs. We draw a comparison to the insurance concept of moral hazard, and we use actuarial techniques to better understand the increase in mission costs due to the availability of reserves. NASA's CADRe database provided the data against which we tested our hypothesis and discovered that there is correlation between the amount of available reserves and project overruns, particularly for mission hardware cost increases. We address the question of how to prevent reserves from increasing mission spending without increasing cost risk to projects.

    Productivity costs occur when the productivity of individuals is affected by illness, treatment, disability or premature death. The objective of this paper was to review past and current developments related to the inclusion, identification, measurement and valuation of productivity costs in economic evaluations. The main debates in the theory and practice of economic evaluations of health technologies described in this review have centred on the questions of whether and how to include productivity costs, especially productivity costs related to paid work. The past few decades have seen important progress in this area. There are important sources of productivity costs other than absenteeism (e.g. presenteeism and multiplier effects in co-workers), but their exact influence on costs remains unclear. Different measurement instruments have been developed over the years, but which instrument provides the most accurate estimates has not been established. Several valuation approaches have been proposed. While empirical research suggests that productivity costs are best included in the cost side of the cost-effectiveness ratio, the jury is still out regarding whether the human capital approach or the friction cost approach is the most appropriate valuation method to do so. Despite the progress and the substantial amount of scientific research, a consensus has not been reached on either the inclusion of productivity costs in economic evaluations or the methods used to produce productivity cost estimates. Such a lack of consensus has likely contributed to ignoring productivity costs in actual economic evaluations and is reflected in variations in national health economic guidelines. Further research is needed to lessen the controversy regarding the estimation of health-related productivity costs. More standardization would increase the comparability and credibility of economic evaluations taking a societal perspective.

Given the lack of generalizability of study results across different settings, many attempts have been made to estimate the economic costs of alcohol for various settings; however, these have mostly been confined to industrialized countries. To our knowledge, there are a very limited number of well-designed studies which estimate the economic costs of alcohol consumption in developing countries, including Thailand. Therefore, this study aims to estimate these economic costs, in Thailand, 2006. Methods This is a prevalence-based, cost-of-illness study. The estimated costs in this study included both direct and indirect costs. Direct costs included health care costs, costs of law enforcement, and costs of property damage due to road-traffic accidents. Indirect costs included costs of productivity loss due to premature mortality, and costs of reduced productivity due to absenteeism and presenteeism (reduced on-the-job productivity. Results The total economic cost of alcohol consumption in Thailand in 2006 was estimated at 156,105.4 million baht (9,627 million US$ PPP or about 1.99% of the total Gross Domestic Product (GDP. Indirect costs outweigh direct costs, representing 96% of the total cost. The largest cost attributable to alcohol consumption is that of productivity loss due to premature mortality (104,128 million baht/6,422 million US$ PPP, followed by cost of productivity loss due to reduced productivity (45,464.6 million baht/2,804 million US$ PPP, health care cost (5,491.2 million baht/339 million US$ PPP, cost of property damage as a result of road traffic accidents (779.4 million baht/48 million US$ PPP, and cost of law enforcement (242.4 million baht/15 million US$ PPP, respectively.

  15. The Economics of NASA Mission Cost Reserves

    Whitley, Sally; Shinn, Stephen

    2012-01-01

    Increases in NASA mission costs are well-noted but not well-understood, and there is little evidence that they are decreasing in frequency or amount over time. The need to control spending has led to analysis of the causes and magnitude of historical mission overruns, and many program control efforts are being implemented to attempt to prevent or mitigate the problem (NPR 7120). However, cost overruns have not abated, and while some direct causes of increased spending may be obvious (requirements creep, launch delays, directed changes, etc.), the underlying impetus to spend past the original budget may be more subtle. Gaining better insight into the causes of cost overruns will help NASA and its contracting organizations to avoid .them. This paper hypothesizes that one cause of NASA mission cost overruns is that the availability of reserves gives project team members an incentive to make decisions and behave in ways that increase costs. We theorize that the presence of reserves is a contributing factor to cost overruns because it causes organizations to use their funds less efficiently or to control spending less effectively. We draw a comparison to the insurance industry concept of moral hazard, the phenomenon that the presence of insurance causes insureds to have more frequent and higher insurance losses, and we attempt to apply actuarial techniques to quantifY the increase in the expected cost of a mission due to the availability of reserves. We create a theoretical model of reserve spending motivation by defining a variable ReserveSpending as a function of total reserves. This function has a positive slope; for every dollar of reserves available, there is a positive probability of spending it. Finally, the function should be concave down; the probability of spending each incremental dollar of reserves decreases progressively. We test the model against available NASA CADRe data by examining missions with reserve dollars initially available and testing whether

  17. Austrian Economics and the Transaction Cost Approach to the Firm

    Directory of Open Access Journals (Sweden)

    Nicolai J. Foss

    2009-10-01

    Full Text Available As the transaction cost theory of the firm was taking shape in the 1970s, another important movement in economics was emerging: a revival of the ‘Austrian’ tradition in economic theory associated with such economists as Ludwig von Mises and F. A. Hayek (1973; Dolan, 1976; Spadaro, 1978. As Oliver Williamson has pointed out, Austrian economics is among the diverse sources for transaction cost economics. In particular, Williamson frequently cites Hayek (e.g., Williamson, 1985, p. 8; 1991, p. 162, particularly Hayek’s emphasis on adaptation as a key problem of economic organisation (Hayek, 1945. Following Williamson’s lead, a reference to Hayek’s ‘The Use of Knowledge in Society’ (Hayek, 1945 has become almost mandatory in discussions of economic organisation (e.g., Ricketts, 1987, p. 59; Milgrom and Roberts, 1992, p. 56; Douma and Schreuder 1991, p. 9. However, there are many other potential links between Austrian and transaction cost economics that have not been explored closely and exploited.This article argues that characteristically Austrian ideas about property, entrepreneurship, economic calculation, tacit knowledge, and the temporal structure of capital have important implications for theories of economic organisation, transaction cost economics in particular. Austrian economists have not, however, devoted substantial attention to the theory of the firm, preferring to focus on business-cycle theory, welfare economics, political economy, comparative economic systems, and other areas. Until recently the theory of the firm was an almost completely neglected area in Austrian economics, but over the last decade, a small Austrian literature on the firm has emerged. While these works cover a wide variety of theoretical and applied topics, their authors share the view that Austrian insights have something to offer students of firm organisation.

    Full Text Available This study focuses in the effect of integrated nitrogen management to the yield and economic benefits of aerobic rice. This will help farmers to identify which of the two management technique to use to save costs while profit is high. A split plot experiment in Randomized Complete Block design is used with two main treatments and four sub treatments. Main treatments are the use of integrated nitrogen management and an application of synthetic nitrogen fertilizer. Sub treatments are the different rates of nitrogen fertilizer from 0 as control, 90, 120 and 150 kg N ha-1 . Data are consolidated and analyzed using the ANOVA of SAS 9.3 statistical tool and comparison means at 5% significance level in Duncan Multiple Range Test. Grain yield, income, costs, profit and return on expenses are the data gathered. There is an increasing yield from control to 120 kg N ha-1 and started to decline at 150 kg N ha-1 because optimum level reached at 120 kg N ha-1 . Significant increased in yield was observed in plants applied with integrated nitrogen management at 120 kg N ha-1 compared to plants applied with synthetic nitrogen due to release of nitrogen that contributed to the yield of aerobic rice. However, plants applied of 90 kg N ha-1 synthetic nitrogen gives significant yield increased compared to plants with integrated nitrogen management. Yield was subjected to economic analysis using gross income, costs and profit and return on expenses. Plants applied with synthetic nitrogen at 90 kg N ha-1 resulted to high income due to lower costs of fertilizer inputs and only treatment that has a positive return on expenses at 3.2% while other treatments have a negative remarks. This will lead to a conclusion that 90 kg N ha-1 is the optimum level of nitrogen that can give high yield and positive return on expenses that farmers will benefited.

    2018-01-01

    The detrimental impact of smoking on health has been widely documented since the 1960s. Numerous studies have also quantified the economic cost that smoking imposes on society. However, these studies have mostly been in high income countries, with limited documentation from developing countries. The aim of this paper is to measure the economic cost of smoking-attributable diseases in countries throughout the world, including in low- and middle-income settings. The Cost of Illness approach is used to estimate the economic cost of smoking attributable-diseases in 2012. Under this approach, economic costs are defined as either 'direct costs' such as hospital fees or 'indirect costs' representing the productivity loss from morbidity and mortality. The same method was applied to 152 countries, which had all the necessary data, representing 97% of the world's smokers. The amount of healthcare expenditure due to smoking-attributable diseases totalled purchasing power parity (PPP) $467 billion (US$422 billion) in 2012, or 5.7% of global health expenditure. The total economic cost of smoking (from health expenditures and productivity losses together) totalled PPP $1852 billion (US$1436 billion) in 2012, equivalent in magnitude to 1.8% of the world's annual gross domestic product (GDP). Almost 40% of this cost occurred in developing countries, highlighting the substantial burden these countries suffer. Smoking imposes a heavy economic burden throughout the world, particularly in Europe and North America, where the tobacco epidemic is most advanced. These findings highlight the urgent need for countries to implement stronger tobacco control measures to address these costs. Published by the BMJ Publishing Group Limited.

    The complexities and nuances of evaluating the costs associated with providing medical technologies are often underestimated by analysts engaged in economic evaluations. This article describes the theoretical underpinnings of cost estimation, emphasizing the importance of accounting for opportunity costs and marginal costs. The various types of costs that should be considered in an analysis are described; a listing of specific cost elements may provide a helpful guide to analysis. The process of identifying and estimating costs is detailed, and practical recommendations for handling the challenges of cost estimation are provided. The roles of sensitivity analysis and discounting are characterized, as are determinants of the types of costs to include in an analysis. Finally, common problems facing the analyst are enumerated with suggestions for managing these problems.

    1994-12-01

    The COSYMA program system for evaluating the off-site consequences of accidental releases of radioactive material to the atmosphere includes an ECONOMICS module for assessing economic consequences. The aim of this module is to convert various consequences (radiation-induced health effects and impacts resulting from countermeasures) caused by an accident into the common framework of economic costs; this allows different effects to be expressed in the same terms and thus to make these effects comparable. With respect to the countermeasure 'movement of people', the dominant cost categories are 'loss-of-income costs' and 'costs of lost capital services'. In the original version of the ECONOMICS module these costs are calculated on the basis of the total number of people moved. In order to take into account also regional or local economic peculiarities of a nuclear site, the ECONOMICS module has been extended: Calculation of the above mentioned cost categories is now based on the number of employees in different economic sectors in the affected area. This extension of the COSYMA ECONOMICS module is described in more detail. (orig.)

    Full Text Available Biodiversity conservation requires strategic investment as resources for conservation are often limited. As sea level rises, it is important and necessary to consider both sea level rise and costs in conservation decision making. In this study, we consider costs of conservation in an integrated modeling process that incorporates a geomorphological model (SLAMM, species habitat models, and conservation prioritization (Zonation to identify conservation priorities in the face of landscape dynamics due to sea level rise in the Matanzas River basin of northeast Florida. Compared to conservation priorities that do not consider land costs in the analysis process, conservation priorities that consider costs in the planning process change significantly. The comparison demonstrates that some areas with high conservation values might be identified as lower priorities when integrating economic costs in the planning process and some areas with low conservation values might be identified as high priorities when considering costs in the planning process. This research could help coastal resources managers make informed decisions about where and how to allocate conservation resources more wisely to facilitate biodiversity adaptation to sea level rise.

    Full Text Available Aims. To examine all relevant literature on the economic costs of osteoarthritis in the UK, and to compare such costs globally. Methods. A search of MEDLINE was performed. The search was expanded beyond peer-reviewed journals into publications by the department of health, national orthopaedic associations, national authorities and registries, and arthritis charities. Results. No UK studies were identified in the literature search. 3 European, 6 North American, and 2 Asian studies were reviewed. Significant variation in direct and indirect costs were seen in these studies. Costs for topical and oral NSAIDs were estimated to be £19.2 million and £25.65 million, respectively. Cost of hip and knee replacements was estimated to exceed £850 million, arthroscopic surgery for osteoarthritis was estimated to be £1.34 million. Indirect costs from OA caused a loss of economic production over £3.2 billion, £43 million was spent on community services and £215 million on social services for osteoarthritis. Conclusions. While estimates of economic costs can be made using information from non-published data, there remains a lack of original research looking at the direct or indirect costs of osteoarthritis in the UK. Differing methodology in calculating costs from overseas studies makes direct comparison with the UK difficult.

    2006-06-01

    Cost-of-illness (COI) was the first economic evaluation technique used in the health field. The principal aim was to measure the economic burden of illness to society. Its usefulness as a decision-making tool has however been questioned since its inception. The main criticism came from welfare economists who rejected COIs because they were not grounded in welfare economics theory. Other attacks related to the use of the human capital approach (HCA) to evaluate morbidity and mortality costs since it was said that the HCA had nothing to do with the value people attach to their lives. Finally, objections were made that COI could not be of any help to decision makers and that other forms of economic evaluation (e.g. cost-effectiveness, cost-benefit analysis) would be much more useful to those taking decisions and ranking priorities. Conversely, it is here suggested that COI can be a good economic tool to inform decision makers if it is considered from another perspective. COI is a descriptive study that can provide information to support the political process as well as the management functions at different levels of the healthcare organisations. To do that, the design of the study must be innovative, capable of measuring the true cost to society; to estimate the main cost components and their incidence over total costs; to envisage the different subjects who bear the costs; to identify the actual clinical management of illness; and to explain cost variability. In order to reach these goals, COI need to be designed as observational bottom-up studies.

    2012-01-01

    Financial costs of investing in people is associated with training, acquisition, recruiting, and resolving human errors have a significant impact on increased total ownership costs. These costs can also affect the exaggerate budgets and delayed schedules. The study of human performance economical assessment in the system acquisition process enhances the visibility of hidden cost drivers which support program management informed decisions. This paper presents the literature review of human total ownership cost (HTOC) and cost impacts on overall system performance. Economic value assessment models such as cost benefit analysis, risk-cost tradeoff analysis, expected value of utility function analysis (EV), growth readiness matrix, multi-attribute utility technique, and multi-regressions model were introduced to reflect the HTOC and human performance-technology tradeoffs in terms of the dollar value. The human total ownership regression model introduces to address the influencing human performance cost component measurement. Results from this study will increase understanding of relevant cost drivers in the system acquisition process over the long term.

    Full Text Available doi: http://dx.doi.org/10.15447/sfews.2016v14iss2art4Groundwater management is important and challenging, and nowhere is this more evident than in California. Managed aquifer recharge (MAR projects can play an important role in ensuring California manages its groundwater sustainably. Although the benefits and economic costs of surface water storage have been researched extensively, the benefits and economic costs of MAR have been little researched. Historical groundwater data are sparse or proprietary within the state, often impairing groundwater analyses. General obligation bonds from ballot propositions offer a strategic means of mining information about MAR projects, because the information is available publicly. We used bond-funding applications to identify anticipated MAR project benefits and proposed economic costs. We then compared these costs with actual project costs collected from a survey, and identified factors that promote or limit MAR. Our analysis indicates that the median proposed economic cost for MAR projects in California is $410 per acre-foot per year ($0.33 per cubic meter per year. Increasing Water Supply, Conjunctive Use, and Flood Protection are the most common benefits reported. Additionally, the survey indicates that (1 there are many reported reasons for differences between proposed and actual costs ($US 2015 and (2 there is one primary reason for differences between proposed recharge volumes and actual recharge volumes (AFY: availability of source water for recharge. Although there are differences between proposed and actual costs per recharge volume ($US 2015/AFY, the ranges for proposed costs per recharge volume and actual costs per recharge volume for the projects surveyed generally agree. The two most important contributions to the success of a MAR project are financial support and good communication with stakeholders.

    Remer, D. S.

    1977-01-01

    A mathematical model is developed for calculating the life cycle costs for a project where the operating costs increase or decrease in a linear manner with time. The life cycle cost is shown to be a function of the investment costs, initial operating costs, operating cost gradient, project life time, interest rate for capital and salvage value. The results show that the life cycle cost for a project can be grossly underestimated (or overestimated) if the operating costs increase (or decrease) uniformly over time rather than being constant as is often assumed in project economic evaluations. The following range of variables is examined: (1) project life from 2 to 30 years; (2) interest rate from 0 to 15 percent per year; and (3) operating cost gradient from 5 to 90 percent of the initial operating costs. A numerical example plus tables and graphs is given to help calculate project life cycle costs over a wide range of variables.

  13. An economic and legal perspective on electric utility transition costs

    1996-07-01

    The issue of possibly unrecoverable cost incurred by a utility, or `stranded costs,` has emerged as a major obstacle to developing a competitive generation market. Stranded or transition costs are defined as costs incurred by a utility to serve its customers that were being recovered in rates but are no longer due to availability of lower-priced alternative suppliers. The idea of `stranded cost,` and more importantly arguments for its recovery, is a concept with little basis in economic theory, legal precedence, or precedence in other deregulated industries. The main argument recovery is that the ``regulatory compact`` requires it. This is based on the misconception that the regulator compact is simply: the utility incurs costs on behalf of its customers because of the ``obligation to serve`` so, therefore, customers are obligated to pay. This is a mischaracterization of what the compact was and how it developed. Another argument is that recovery is required for economic efficiency. This presumes, however, a very narrow definition of efficiency based on preventing ``uneconomic`` bypass of the utility and that utilities minimize costs. A broader definition of efficiency and the likelihood of cost inefficiencies in the industry suggest that the cost imposed on customers from inhibiting competition could exceed the gains from preventing uneconomic bypass. Both these issues are examined in this paper.

    Over the last decade, the prevalence of obesity (BMI ≥ 25 kg/m2) in Thailand has been rising rapidly and consistently. Estimating the cost of obesity to society is an essential step in setting priorities for research and resource use and helping improve public awareness of the negative economic impacts of obesity. This prevalence-based, cost-of-illness study aims to estimate the economic costs of obesity in Thailand. The estimated costs in this study included health care cost, cost of productivity loss due to premature mortality, and cost of productivity loss due to hospital-related absenteeism. The Obesity-Attributable Fraction (OAF) was used to estimate the extent to which the co-morbidities were attributable to obesity. The health care cost of obesity was further estimated by multiplying the number of patients in each disease category attributable to obesity by the unit cost of treatment. The cost of productivity loss was calculated using the human capital approach. The health care cost attributable to obesity was estimated at 5,584 million baht or 1.5% of national health expenditure. The cost of productivity loss attributable to obesity was estimated at 6,558 million baht - accounting for 54% of the total cost of obesity. The cost of hospital-related absenteeism was estimated at 694 million baht, while the cost of premature mortality was estimated at 5,864 million baht. The total cost of obesity was then estimated at 12,142 million baht (725.3 million US$PPP, 16.74 baht =1 US$PPP accounting for 0.13% of Thailand's Gross Domestic Product (GDP). Obesity imposes a substantial economic burden on Thai society especially in term of health care costs. Large-scale comprehensive interventions focused on improving public awareness of the cost of and problems associated with obesity and promoting a healthy lifestyle should be regarded as a public health priority.

    Full Text Available Background: Road traffic accidents, considered as global tragedies, are in increasing trend however, the safety situation is very severe in developing countries incurring substantial amount of human, economic and social costs. Motorcycle crashes, the commonest form, occur mostly on economically active population. However, there is limited coverage of studies on economic burden of motorcycle crashes. This study aims to estimate the total cost and DALYs lost due to motorbike accidents among victims of Kathmandu Valley.Materials and Methods: Retrospective cross-sectional study was conducted among the patients having history of motorbike accidents within past twelve months and at least 3 months from the date of data collection. Interview was conducted using proforma among 100 victims of accidents and their care giver in case of death from November 15, 2014 to May 15, 2015. Cost estimation of motorbike accident was done based on human capital approach. Data collection tool was pretested and collected data were analyzed by SPSS and Microsoft excel. Results: Males (79% belonging to the economically productive age group shared the highest proportion among total accidents victims. Most common reason for accidents was reported to be poor road condition (41%. Indirect cost was found to be significantly higher than direct costs highlighting its negative impact on economy of family and nation due to productivity loss. Total Disability Adjusted Life Years (DALYs lost per person was found to be 490 years and national estimation showed large burden of motorbike accidents due to huge DALY loss.Conclusions: For low resource countries like Nepal, high economic costs of motorbike accidents can pose additional burden to the fragile health system. These accidents can be prevented, and their consequences can be alleviated. There is an urgent need for reinforcement of appropriate interventions and legislation to decrease the magnitude of it and its associated grave

    Parasites have a major impact on global finfish and shellfish aquaculture, having significant effects on farm production, sustainability and economic viability. Parasite infections and impacts can, according to pathogen and context, be considered to be either unpredictable/sporadic or predictable/regular. Although both types of infection may result in the loss of stock and incur costs associated with the control and management of infection, predictable infections can also lead to costs associated with prophylaxis and related activities. The estimation of the economic cost of a parasite event is frequently complicated by the complex interplay of numerous factors associated with a specific incident, which may range from direct production losses to downstream socio-economic impacts on livelihoods and satellite industries associated with the primary producer. In this study, we examine the world's major marine and brackish water aquaculture production industries and provide estimates of the potential economic costs attributable to a range of key parasite pathogens using 498 specific events for the purposes of illustration and estimation of costs. This study provides a baseline resource for risk assessment and the development of more robust biosecurity practices, which can in turn help mitigate against and/or minimise the potential impacts of parasite-mediated disease in aquaculture.

    Valuation of health effects of air pollution is becoming a critical component of the performance of cost-benefit analysis of pollution control measures, which provides a basis for setting priorities for action. Beijing has focused on control of transport emission as vehicular emissions have recently become an important source of air pollution, particularly during Olympic games and Post-games. In this paper, we conducted an estimation of health effects and economic cost caused by road transport-related air pollution using an integrated assessment approach which utilizes air quality model, engineering, epidemiology, and economics. The results show that the total economic cost of health impacts due to air pollution contributed from transport in Beijing during 2004-2008 was 272, 297, 310, 323, 298 million US (mean value), respectively. The economic costs of road transport accounted for 0.52, 0.57, 0.60, 0.62, and 0.58% of annual Beijing GDP from 2004 to 2008. Average cost per vehicle and per ton of PM 10 emission from road transport can also be estimated as 106 US /number and 3584 US $ t -1, respectively. These findings illustrate that the impact of road transport contributed particulate air pollution on human health could be substantial in Beijing, whether in physical and economic terms. Therefore, some control measures to reduce transport emissions could lead to considerable economic benefit.

    Narrod, Clare; Zinsstag, Jakob; Tiongco, Marites

    2012-06-01

    This article presents an integrated epidemiological and economic framework for assessing zoonoses using a "one health" concept. The framework allows for an understanding of the cross-sector economic impact of zoonoses using modified risk analysis and detailing a range of analytical tools. The goal of the framework is to link the analysis outputs of animal and human disease transmission models, economic impact models and evaluation of risk management options to gain improved understanding of factors affecting the adoption of risk management strategies so that investment planning includes the most promising interventions (or sets of interventions) in an integrated fashion. A more complete understanding of the costs of the disease and the costs and benefits of control measures would promote broader implementation of the most efficient and effective control measures, contributing to improved animal and human health, better livelihood outcomes for the poor and macroeconomic growth.

    Solar processes are generally characterized by high first cost and low operating costs. Therefore, the basic economic problem is one of comparing an initial known investment with estimated future operating cost. This paper present the cost-benefit ratio of solar collector with integrated storage system. Evaluation of the annual cost (AC) and the annual energy gain (AEG) of the collector are performed and the ratio of AC/AEG or the cost benefit ratio is presented for difference combination of mass flow rate, solar collector length and channel depth. Using these cost-effectiveness curves, the user can select optimum design features, which correspond to minimum AC/AEG

    In May 2011, the Food and Drug Administration approved fidaxomicin for the treatment of Clostridium difficile infection (CDI). It has been found to be noninferior to vancomycin; however, its cost-effectiveness for the treatment of CDI remains undetermined. We developed a decision analytic simulation model to determine the economic value of fidaxomicin for CDI treatment from the third-party payer perspective. We looked at CDI treatment in these 3 cases: (1) no fidaxomicin, (2) only fidaxomicin, and (3) fidaxomicin based on strain typing results. The incremental cost-effectiveness ratio for fidaxomicin based on screening given current conditions was >$43.7 million per quality-adjusted life-year and using only fidaxomicin was dominated (ie, more costly and less effective) by the other 2 treatment strategies explored. The fidaxomicin strategy tended to remain dominated, even at lower costs. With approximately 50% of CDI due to the NAP1/BI/027 strain, a course of fidaxomicin would need to cost ≤$150 to be cost-effective in the treatment of all CDI cases and between $160 and $400 to be cost-effective for those with a non-NAP1/BI/027 strain (ie, treatment based on strain typing). Given the current cost and NAP1/BI/027 accounting for approximately 50% of isolates, using fidaxomicin as a first-line treatment for CDI is not cost-effective. However, typing and treatment with fidaxomicin based on strain may be more promising depending on the costs of fidaxomicin.

  7. Evaluating economic costs and benefits of climate resilient livelihood strategies

    2016-01-01

    Full Text Available A major challenge for international development is to assist the poorest regions to achieve development targets while taking climate change into account. Such ‘climate resilient development’ (CRD must identify and implement adaptation strategies for improving livelihoods while also being cost-effective. While the idea that climate resilience and development goals should be compatible is often discussed, empirical evaluations of the economic impacts of actual CRD investments are practically non-existent. This paper outlines a framework to evaluate economic returns to CRD and applies it in two adaptation strategies trialed in Nusa Tenggara Barat Province, eastern Indonesia. The evaluation framework is composed of three models: a household benefit cost model, a diffusion model, and a regional benefit cost model. The models draw upon the impact evaluation, technology diffusion, and risk assessment literatures, respectively. The analyzes are based on expert opinion and locally-derived information, and hence can be applied in data-poor situations typical of developing countries. Our results explore economic costs and benefits at the household and regional scale, and we identify key input variables that greatly influence the economic returns of the strategies. These variables should therefore be a focus of ongoing investment. We also discuss how the framework is more generally applicable, its limitations including challenges in accounting for less tangible social and ecosystem service benefits, potentially leading to the underestimation of impacts, and how the approach should be complemented by qualitative methods.

    2013-01-01

    To estimate the total economic burden of physical inactivity in China. The costs of physical inactivity combine the medical and non-medical costs of five major Non Communicable Diseases (NCDs) associated with inactivity. The national data from the Chinese Behavioral Risk Factors Surveillance Surveys (2007) and the National Health Service Survey (2003) are used to compute population attributable risks (PARs) of inactivity for each major NCD. Costs specific to inactivity are obtained by multiplying each disease costs by the PAR for each NCD, by incorporating the inactivity effects through overweight and obesity. Physical inactivity contributes between 12% and 19% to the risks associated with the five major NCDs in China, namely coronary heart disease, stroke, hypertension, cancer, and type 2 diabetes. Physical inactivity is imposing a substantial economic burden on the country, as it is responsible alone for more than 15% of the medical and non-medical yearly costs of the main NCDs in the country. The high economic burden of physical inactivity implies the need to develop more programs and interventions that address this modifiable behavioral risk, in order to curb the rising NCDs epidemic in China.

    Health economists are increasingly interested in integrated care in order to support decision-makers to find cost-effective solutions able to tackle the threat that chronic diseases pose on population health and health and social care budgets. However, economic evaluation in integrated care is still in its early years, facing several difficulties. The aim of this paper is to describe the unique nature of integrated care as a topic for economic evaluation, explore the obstacles to perform economic evaluation, discuss methods and techniques that can be used to address them, and set the basis to develop a research agenda for health economics in integrated care. The paper joins the voices that call health economists to pay more attention to integrated care and argues that there should be no more time wasted for doing it. PMID:28316543

    This work resulted from a continuing multidisciplinary analysis of species preservation and global change. The paper explores the economic cost of a potential regional warming as it affects one Pacific Northwest natural resource, the spring chinook salmon (Oncorhynchus tshcawytscha). Climate change and planned habitat improvements impact the production and economic value of soling chinook salmon of the Yakima River tributary of the Columbia River in eastern Washington. The paper presents a derivation of the total economic value of a chinook salmon, which includes the summation of the existence, commercial, recreational, and capital values of the fish. When currently available commercial, recreational, existence, and capital values for chinook salmon were applied to estimated population changes, the estimated change in the economic value per fish associated with reduction of one fish run proved significant

  12. Economics of integrated MTBE/TAME/DIPE production

    Denney, R.G.

    1993-01-01

    Because of the 1990 Clean Air Act (CAA), the 1993 demand for oxygenates (i.e. MTBE, TAME, DIPE) for motor gasoline blending in PADD IV and V is estimated to total 166,000 bpd. Existing PADD IV and V oxygenate producers can only supply about 13% of this demand. The shortfall must be supplied from oxygenate producers in PADD III or from Canadian and offshore sources. This paper examines the economics of locating an integrated plant in Southwest Wyoming (PADD IV), to supply approximately 6,800 bpd of the PADD IV and V demand by producing MTBE, TAME, and DIPE from natural gas liquids (NGL). The Southwest Wyoming location offers the advantage of being closer to the PADD IV and V markets than the producers in PADD III and the availability of a relatively inexpensive NGL feedstock that has no other market than the Midwest or US Gulf Coast via MAPCO's NGL pipeline. With these location and feedstock cost advantages, the Southwest Wyoming integrated MTBE, TAME, DIPE plant offers an attractive return on investment and economics comparable to those of a World Scale, 12,500 bpd mixed butane feed MTBE plant in PADD III

    2015-09-15

    This paper presents an application of integrated methodological approach for identifying cost-effective combinations of agri-environmental measures to achieve water quality targets. The methodological approach involves linking hydro-chemical modelling with economic costs of mitigation measures. The utility of the approach was explored for the River Dee catchment in North East Scotland, examining the cost-effectiveness of mitigation measures for nitrogen (N) and phosphorus (P) pollutants. In-stream nitrate concentration was modelled using the STREAM-N and phosphorus using INCA-P model. Both models were first run for baseline conditions and then their effectiveness for changes in land management was simulated. Costs were based on farm income foregone, capital and operational expenditures. The costs and effects data were integrated using 'Risk Solver Platform' optimization in excel to produce the most cost-effective combination of measures by which target nutrient reductions could be attained at a minimum economic cost. The analysis identified different combination of measures as most cost-effective for the two pollutants. An important aspect of this paper is integration of model-based effectiveness estimates with economic cost of measures for cost-effectiveness analysis of land and water management options. The methodological approach developed is not limited to the two pollutants and the selected agri-environmental measures considered in the paper; the approach can be adapted to the cost-effectiveness analysis of any catchment-scale environmental management options.

  14. Economic implications of nuclear operating and maintenance costs

    International Nuclear Information System (INIS)

    Braun, C.

    1994-01-01

    Nuclear operating and maintenance (O and M) costs for U.S. plants have been increasing during the decade of the 1980's. Costs have stabilized over the last five years but have not yet significantly declined. Annual capacity factors have considerably improved during the last eight years and unit O and M costs expressed in Mills Kwh have thus declined. Two other important trends evident over the last five years have been the decline in fossil fuel prices and the transition to deregulated electric utilities market, accelerated with the passage of the 1992 Energy Policy Act. Within the next five years it may be possible for large scale industrial customers to directly contract with electricity generators, by they utilities or independent power producers (IPP's) for supplying their power requirements. The ability of such customers to directly contract with potential supplies based on low cost performance bypassing their local utility, may have significant implications for the structure of the utility industry in the near term and for plant operations. A greater pressure will likely be exerted on all plants, including nuclear to reduce operating costs so as to remain competitive with other power suppliers in their markets. Nuclear O and M costs are likely to be heavily scrutinized for possible savings and reductions. The electric utilities mergers waves and the nuclear industry's initiative on O and M cost control both aim at improving plant economics so as to better compete in the more deregulated environment. In this climate the issues of why nuclear O and M costs have increased, what can be done to reduce costs and what are the implications for advanced reactors design and economics are discussed. 14 figs

    Vitamin and mineral deficiencies adversely affect a third of the world's people. Consequently, a series of global goals and a serious amount of donor and national resources have been directed at such micronutrient deficiencies. Drawing on the extensive experience of the authors in a variety of institutional settings, the article used a computer search of the published scientific literature of the topic, supplemented by reports and published and unpublished work from the various agencies. In examining the effect of sex on the economic and social costs of micronutrient deficiencies, the paper found that: (1) micronutrient deficiencies affect global health outcomes; (2) micronutrient deficiencies incur substantial economic costs; (3) health and nutrition outcomes are affected by sex; (4) micronutrient deficiencies are affected by sex, but this is often culturally specific; and finally, (5) the social and economic costs of micronutrient deficiencies, with particular reference to women and female adolescents and children, are likely to be considerable but are not well quantified. Given the potential impact on reducing infant and child mortality, reducing maternal mortality, and enhancing neuro-intellectual development and growth, the right of women and children to adequate food and nutrition should more explicitly reflect their special requirements in terms of micronutrients. The positive impact of alleviating micronutrient malnutrition on physical activity, education and productivity, and hence on national economies suggests that there is also an urgent need for increased effort to demonstrate the cost of these deficiencies, as well as the benefits of addressing them, especially compared with other health and nutrition interventions.

  17. Cost Assessment Methodology and Economic Viability of Tidal Energy Projects

    2017-11-01

    Full Text Available The exploitation of technologies with which to harness the energy from ocean currents will have considerable possibilities in the future thanks to their enormous potential for electricity production and their high predictability. In this respect, the development of methodologies for the economic viability of these technologies is fundamental to the attainment of a consistent quantification of their costs and the discovery of their economic viability, while simultaneously attracting investment in these technologies. This paper presents a methodology with which to determine the economic viability of tidal energy projects, which includes a technical study of the life-cycle costs into which the development of a tidal farm can be decomposed: concept and definition, design and development, manufacturing, installation, operation and maintenance and dismantling. These cost structures are additionally subdivided by considering their sub-costs and bearing in mind the main components of the tidal farm: the nacelle, the supporting tidal energy converter structure and the export power system. Furthermore, a technical study is developed in order to obtain an estimation of the annual energy produced (and, consequently, the incomes generated if the electric tariff is known by considering its principal attributes: the characteristics of the current, the ability of the device to capture energy and its ability to convert and export the energy. The methodology has been applied (together with a sensibility analysis to the particular case of a farm composed of first generation tidal energy converters in one of the Channel Island Races, the Alderney Race, in the U.K., and the results have been attained by means of the computation of engineering indexes, such as the net present value, the internal rate of return, the discounted payback period and the levelized cost of energy, which indicate that the proposed project is economically viable for all the case studies.

    Nowadays, the use of energy is growing especially in transportation and electricity industries. However this energy is based on conventional sources which pollute the environment. Multi-source system is seen as the best solution to sustainable development. This paper proposes the Economic Dispatch (ED) of hybrid renewable power system. The hybrid system is composed of ten thermal generators, photovoltaic (PV) generator and wind turbine generator. To show the importance of renewable energy sources (RES) in the energy mix we have ran the simulation for system integrated PV only and PV plus wind. The result shows that the system with renewable energy sources (RES) is more compromising than the system without RES in terms of fuel cost.

    Low cost electricity was a key factor for establishing an aluminium industry in Quebec. Smelters in the province use 50 terawatt hours of electricity per year, which represents 25 per cent of the total consumed in Quebec. This article assessed the profitability of new industrial projects that require large quantities of electricity at a time when the cost of new power plants is increasing. However, electricity is being sold below cost and the difference is subsidized by the government. The investment is justified by the government because these new projects create high paying jobs. The authors presented cases of 2 new aluminium plants, and concluded that they represented a very high economic cost for the province. 1 tab

    In the developed countries having existing nuclear programs, the situation necessitates lower total power generation cost. The restructuring of utility industry due to the deregulation causes to reorganize the ownership of some nuclear plants, and the overall economics of nuclear plants in relation to their local competition is reexamined. The reluctance to make any new long term capital cost commitment arises, and it makes new plant construction less likely in near future, and plant upgrading and improvement to be put to intense scrutiny. The capital cost recovery in existing nuclear plants in USA is discussed. It is important to recognize that there is very little that can be done to affect already expended capital, and only that can be done is to improve plant capacity factors, besides write-off. The roles of architects and engineers in improved plant economics are now evaluated by the various organizations which are interested in the participation in new nuclear industry reorganization and restructuring. The reduction of operation and maintenance costs and capital investment, and the improvement of capacity factor are reported. In new ALWR construction program, architects and engineers can significantly support the control of plant capital costs by the selection of the plant design and the sites, and the strategies of procurement and contract, construction schedule and others.

  1. Cost of illness and economic evaluation in rare diseases.

    López-Bastida, Julio; Oliva-Moreno, Juan

    2010-01-01

    Rare diseases are a major cause of morbidity and mortality in high income countries and have major repercussions on individuals and health care systems. This chapter examines the health economy of rare diseases from two different perspectives: firstly, the study of the economic impact of rare diseases (Cost of Illness studies); and, secondly, cost-effectiveness evaluation, which evaluates both the costs and results of the health care technologies applied in rare diseases. From the point of view of economics, health resource allocation is based on the principle of scarcity, as there are not - and never will be- sufficient resources for all worthy objectives. Hence, policy makers should balance costs and health outcomes. Rare diseases may well represent a significant societal burden that should rightly receive appropriate prioritisation of health care resources. As new and seemingly expensive health care technologies are developed for rare diseases, it will become increasingly important to evaluate potential and real impact of these new technologies in both dimensions: social costs and health outcomes.

  2. SIR (Safe Integral Reactor) - reducing size can reduce cost

    International Nuclear Information System (INIS)

    Hayns, M.R.

    1991-01-01

    Traditional engineering economics have favoured the advantages of larger size as a means of reducing specific capital costs and hence unit generating costs. For large and small plants utilising the same concept, e.g. a small four-loop PWR vs a large four-loop PWR with the same number of components, economies of scale are well established. If, however, a smaller plant is sized to take advantage of features which are only feasible at smaller outputs, is of simpler design, with the advantage taken of the simplified design to produce the most cost-effective layout, and incorporates fewer, more easily replaceable components with minimal assembly on site, it is possible to produce a plant which is competitive with larger plant of more traditional design. When 'system' effects, such as better matching of installed capacity to the growth in demand and the fact that a smaller total capacity will be needed to meet a given demand with a specified level of confidence, are taken into account, it can be shown that a utility's overall cash-flow position can be improved with lower associated absolute financial risks. The UK/US Safe Integral Reactor (SIR) is an integral pressurized water reactor in the 300-400 MW(e) range which utilises conventional water reactor technology in a way not feasible at the very large, sizes of recent years. The SIR concept is briefly explained and its technical and economic advantages in terms of simplicity, construction, maintenance, availability, decommissioning, safety and siting described. The results of system analyses which demonstrate the overall financial advantages to a utility are presented. (author)

  3. Economic costs of drug abuse: financial, cost of illness, and services.

    Cartwright, William S

    2008-03-01

    This article examines costs as they relate to the financial costs of providing drug abuse treatment in private and public health plans, costs to society relating to drug abuse, and many smaller costing studies of various stakeholders in the health care system. A bibliography is developed from searches across PubMed, Web of Science, and other bibliographic sources. The review indicates that a wide collection of cost findings is available to policy makers. For example, the financial aspects of health plans have been dominated by considerations of actuarial costs of parity for drug abuse treatment. Cost-of-illness methods have been developed and extended to drug abuse costing to measure the national level of burden and are important to the economic evaluation of interventions at the program level. Costing is done in many small and focused studies, reflecting the interests of different stakeholders in the health care system. For costs in programs and health plans, as well as cost offsets of the impact of substance abuse treatment on medical expenditures, findings are surprisingly important to policy makers. Maintaining ongoing research that is highly policy relevant from the point of view of health services, more is needed on costing concepts and measurement applications.

    In the 1980's it was popular to introduce incentive systems for the promotion of taxpayer compliance. The partial VAT refunds for consumer purchases that are examined in this paper represent one of such schemes. The partial VAT refund system was an idea that was popular amongst professional tax administrators in the 1980s and as a consequence was implemented throughout Central America, Bolivia and Turkey. Such proposals were made with little or no research on the compliance or economic costs ...

    The book presents the lectures delivered during a short course held at Urbino University in summer 2015 on qualitative theory of dynamical systems, included in the activities of the COST Action IS1104 “The EU in the new economic complex geography: models, tools and policy evaluation”. It provides a basic introduction to dynamical systems and optimal control both in continuous and discrete time, as well as some numerical methods and applications in economic modelling. Economic and social systems are intrinsically dynamic, characterized by interdependence, nonlinearity and complexity, and these features can only be approached using a qualitative analysis based on the study of invariant sets (equilibrium points, limit cycles and more complex attractors, together with the boundaries of their basins of attraction), which requires a trade-off between analytical, geometrical and numerical methods. Even though the early steps of the qualitative theory of dynamical systems have been in continuous time models, in e...

    The goal of this study was to estimate the cost of production of 1 unit of blood from a National Health Service perspective in Greece. In agreement with guidelines, the cost of blood production in this study accounted only for the resources expended for collection, processing, laboratory testing, and storage. Hence, the costs associated with donor recruitment, pretransfusion preparation, transfusion administration, follow-up management of adverse events, and other long-term relevant costs were not taken into consideration. The indirect cost of blood donations for donors (productivity loss) was also considered. A questionnaire was used to collect data regarding personnel time, annual blood quantities collected, percentage of wastage, utilization of consumables, institutional overhead, information technology expenditure, medical equipment utilized, nuclear acid tests, and other factors. Data gathered by 53 hospitals across the country were assessed. A model was constructed with economic data collected by the National School of Public Health and the Ministry of Health. All data refer to the year 2013. The weighted mean direct cost of producing 1 unit of blood was estimated at €131.49 (SD, €22.12; minimum/maximum, €94.96-€239.20). The mean total indirect cost was estimated at €34 per unit of blood. The cost distribution was positively skewed (skewness, 1.642 [0.327]). The major cost component was the cost of personnel, accounting for 32.5% of total costs, and the average of blood unit wastage was estimated at 4.90%. There were no differences between the cost of producing 1 unit of blood in Athens compared with the rest of the country (Mann-Whitney test, P = 0.341). This study suggests that the cost of producing 1 unit of blood is not insignificant. These figures need to be complemented with those concerning the cost of transfusion to have a complete picture of producing and using 1 unit of blood locally.

    Full Text Available In the era of economic globalization, promoting regional trade agreements or regional cooperation has become a plausible strategy to attract foreign direct investment and to promote national competitiveness at a global level. Nonetheless, facing the differential national economic interests and the needs of protection of domestic industries, as well as the diverse levels of economic liberalization domestically, the involvement of FTA negotiation in every country is universally in the situation of struggling between securing economic sovereignty and national economic development. Countries in the Asia-Pacific region are in the same situation. This article analyzes how countries balance between securing economic sovereignty and promoting national economic development when they are involved in TPP and RCEP negotiations. By confirming the appropriate linkage between each participating countries’ decision for balancing between domestic economic sovereignty and further integrating into regional economic cooperation institutions the validity of the proposition for this research project can be verified.

    Fibromyalgia (FM) is characterized by widespread pain that can lead to significant patient disability, complex management decisions for physicians, and economic burden on society. We investigated the total costs of FM in an employer population. Administrative claims data of a Fortune 100 manufacturer were used to quantify direct (i.e., medical and pharmaceutical claims) and indirect (i.e., disability claims and imputed absenteeism) costs associated with FM. A total of 4699 patients with at least one FM claim between 1996 and 1998 were contrasted with a 10% random sample of the overall beneficiary population. Employee-only subsets of both samples also were drawn. Medical utilization, receipt of prescription drugs, and annual total costs were proportionately similar yet significantly greater among FM claimants than the overall sample (all p < 0.0001). Total annual costs for FM claimants were $5945 versus $2486 for the typical beneficiary (p < 0.0001). Six percent of these costs were attributable to FM-specific claims. The prevalence of disability was twice as high among FM employees than overall employees (p < 0.0001). For every dollar spent on FM-specific claims, the employer spent another $57 to $143 on additional direct and indirect costs. Hidden costs of disability and comorbidities greatly increase the true burden of FM. Regardless of the clinical understanding of FM, when a claim for FM is present, considerable costs are involved. Findings suggest that within the management of FM there may be large cost-offset opportunities for reductions in patient, physician, and employer burdens.

    Obesity in the United States is a socioeconomic issue. It is related to limited social and economic resources and may be linked to disparities in access to healthy foods. Added sugars and added fats are far more affordable than are the recommended "healthful" diets based on lean meats, whole grains, and fresh vegetables and fruit. There is an inverse relationship between energy density of foods (kJ/g) and energy cost ($/MJ), such that energy-dense grains, fats, and sweets represent the lowest-cost dietary options to the consumer. Good taste, high convenience, and the low cost of energy-dense foods, in conjunction with large portions and low satiating power, may be the principal reasons for overeating and weight gain. Financial disparities in access to healthier diets may help explain why the highest rates of obesity and diabetes are found among minorities and the working poor. If so, then encouraging low-income households to consume more costly foods is not an effective strategy for public health. What is needed is a comprehensive policy approach that takes behavioral nutrition and the economics of food choice into account.

  14. Energy integration: Regional economic integration lever and possible insertion factor in the global economy

    Lokolo, M.C.

    2001-01-01

    In the 1920s, just after the War, an idea began taking root in the Old Continent, to build what could be described as the United States of Europe. Thirty years later, in 1951, a new source of energy, coal, paved the way for the economic integration of Europe. It culminated into monetary integration in January 2002. Economic integration makes sense in the context of the relatively small size of some national economies and markets, and the judicious utilization of rare resources and their unequal distribution. In this document, the author elaborated on the principles at play in economic integration and argued that the integration of the national energy markets could be the lever for economic integration through the gradual elimination of the various obstacles to trade. The author first presented a brief historical overview of economic integration from the perspective of global economic relationships, covering the period between the two world wars to the General Agreement on Tariffs and Trade (GATT) to the World Trade Organization (WTO). The concept and the forms of economic integration were reviewed. Energy integration as a lever of regional economic integration and as a factor in global economic insertion were discussed. Energy integration is a tool for the improvement of the human condition. 15 refs

    Oostenbrink, Jan B; Koopmanschap, Marc A; Rutten, Frans F H

    2002-01-01

    The lack of a uniform costing methodology is often considered a weakness of economic evaluations that hinders the interpretation and comparison of studies. Standardisation is therefore an important topic within the methodology of economic evaluations and in national guidelines that formulate the formal requirements for studies to be considered when deciding on the reimbursement of new medical therapies. Recently, the Dutch Manual for Costing: Methods and Standard Costs for Economic Evaluations in Health Care (further referred to as "the manual") has been published, in addition to the Dutch guidelines for pharmacoeconomic research. The objectives of this article are to describe the main content of the manual and to discuss some key issues of the manual in relation to the standardisation of costs. The manual introduces a six-step procedure for costing. These steps concern: the scope of the study;the choice of cost categories;the identification of units;the measurement of resource use;the monetary valuation of units; andthe calculation of unit costs. Each step consists of a number of choices and these together define the approach taken. In addition to a description of the costing process, five key issues regarding the standardisation of costs are distinguished. These are the use of basic principles, methods for measurement and valuation, standard costs (average prices of healthcare services), standard values (values that can be used within unit cost calculations), and the reporting of outcomes. The use of the basic principles, standard values and minimal requirements for reporting outcomes, as defined in the manual, are obligatory in studies that support submissions to acquire reimbursement for new pharmaceuticals. Whether to use standard costs, and the choice of a particular method to measure or value costs, is left mainly to the investigator, depending on the specific study setting. In conclusion, several instruments are available to increase standardisation in

  17. Baseline development, economic risk, and schedule risk: An integrated approach

    International Nuclear Information System (INIS)

    Tonkinson, J.A.

    1994-01-01

    The economic and schedule risks of Environmental Restoration (ER) projects are commonly analyzed toward the end of the baseline development process. Risk analysis is usually performed as the final element of the scheduling or estimating processes for the purpose of establishing cost and schedule contingency. However, there is an opportunity for earlier assessment of risks, during development of the technical scope and Work Breakdown Structure (WBS). Integrating the processes of risk management and baselining provides for early incorporation of feedback regarding schedule and cost risk into the proposed scope of work. Much of the information necessary to perform risk analysis becomes available during development of the technical baseline, as the scope of work and WBS are being defined. The analysis of risk can actually be initiated early on during development of the technical baseline and continue throughout development of the complete project baseline. Indeed, best business practices suggest that information crucial to the success of a project be analyzed and incorporated into project planning as soon as it is available and usable

    2016-06-01

    Full Text Available Although a social science, economy makes use of the tools of numbers and precise data. Should we not include semiotics in the theory of economic interpretation, the axiomatization of the economic science would be impossible and furthermore the capitalization of the advantages of artificial intelligence that eliminates the inconveniences of equivocal meanings and inflation of words would be useless. Interpretation is an endeavor that implies decoding the hidden meaning of the manifestation of economic processes and phenomena. Semantics and pragmatics – by abstracting and axiomatization – help us overcome the intuition limitations’ in the process of interpretation. Our hypothesis is the human existence develops in an universe of signals and signs whom knowledge, interpretation and use conditions the action of society, groups and single human beings. Our main objective is to prove that in order to grasp the meanings of evolution one needs to understand the meaning of signs. We conclude by suggesting a semiotic symbology that includes all its subcategory: the relations between signs, studied by syntax; the relation between signs and object, the field of semantics; the relation between signs and the subjects (interpreters that use them, meaning pragmatics. The finality is to strengthen the concept of hermeneutic economics by including semiotics in its action field

    2003-01-01

    We present unit costs corresponding to resource information collected in the Schizophrenia Outpatient Health Outcomes (SOHO) Study. The SOHO study is a 3-year, prospective, observational study of health outcomes associated with antipsychotic treatment in out-patients treated for schizophrenia. The study is being conducted across 10 European countries (Denmark, France, Germany, Greece, Ireland, Italy, the Netherlands, Portugal, Spain and the UK) and includes over 10,800 patients and over 1000 investigators. To identify the best available unit costs of hospital admissions, day care and psychiatrist out-patient visits, a tariff-based approach was used. Unit costs were obtained for nine of the 10 countries and were adjusted to 2000 price levels by consumer price indices and converted to US dollars using purchasing power parity rates (and on to Euro). The paper illustrates the need to balance the search for sound unit costs with pragmatic solutions in the costing of international economic evaluations.

  20. The cost of LLW disposal - Is it sound economics?

    International Nuclear Information System (INIS)

    Stelluto, Janis D.

    1992-01-01

    Low-level radioactive waste (LLW) management is a growth industry. Since 1980, when the LLW Policy Act was passed, regional and state LLW bureaucracies have grown, and LLW services and consulting businesses have prospered. Most states and federal agencies have LLW programs with increased regulation of LLW management. Costs of all these programs have soared as facilities for LLW disposal are proposed in sixteen, or more, locations in the country. LLW management costs have also increased as licensees implement comprehensive programs for volume reduction and waste form stabilization. Yet, the total cost of LLW management service is borne by nearly the same universe of payers as in 1980: taxpayers and radioactive materials licensees. Those costs are, in turn, passed on through taxes and consumer costs. Ultimately, everybody pays. Despite this investment, the LLW situation is adrift. New facilities have not been built, and existing facilities are closing or limiting access. LLW management has not advanced to a respected field of engineering and science. Nor does it include exceptional benefit and opportunity to host communities. A new focus is needed to allow an economically sound solution to emerge, one where the supply of LLW management and disposal fits the demand for service. (author)

    Full Text Available The economic integration between the United States and Mexico has affected the economic, political and social relations in the border region. The paper seeks to relate the increasing economic integration and business cycles of the economies of San Diego and Tijuana to the development of both national and binational economic organizations in the border region. The methodology of analysis uses both statistical estimations of the economic integration of San Diego and Tijuana and semi-structured interviews of economic organizations to analyze the increasing economic integration and the role and achievements of the cross-border economic organizations. The results showed that cross-border cooperation is predominately controlled by federal and state governments on both sides of the border. However, the main achievements of cross-border economic cooperation have been accomplished by local private organizations. The perspective of further local economic development greatly depends on both the possibility of increased involvement of federal governments and the growing encouragement of regional organizations.

    2009-01-01

    The WHO asserts that the global food price crisis threatens public health and jeopardizes the health of the most disadvantaged groups such as women, children, the elderly and low-income families. Economic factors play a crucial role and could affect personal nutrition status and health. Economic decision factors such as food price and income do influence people's food choices. Moreover, food costs are a barrier for low income-families to healthier food choices. Several studies indicate that diet costs are associated with dietary quality and also food safety. Food prices have surged over the past couple of years (2007-9) and raised serious concerns about food security around the world. Rising food prices are having severe impacts on population health and nutritional status. Therefore, people who change their diet pattern for economic reasons may develop a range of nutritionally-related disorders and diseases, from so-called over-nutrition to or with under-nutrition even within the one household. This is likely to increase with growing food insecurity. Presently, economics is not integrated with mainstream nutrition science or practice, other than in "home economics", but it can enable greater understanding of how socioeconomic status may interplay with human nutritional status and health and how these situations might be resolved. Collaborative, cross-disciplinary nutritional economics research should play a greater role in the prevention and management of food crises.

    2007-04-01

    Full Text Available Abstract This paper addresses the potential for using economic regulation, e.g. taxes or subsidies, as instruments to combat the increasing problems of inappropriate diets, leading to health problems such as obesity, diabetes 2, cardiovascular diseases etc. in most countries. Such policy measures may be considered as alternatives or supplements to other regulation instruments, including information campaigns, bans or enhancement of technological solutions to the problems of obesity or related diseases. 7 different food tax and subsidy instruments or combinations of instruments are analysed quantitatively. The analyses demonstrate that the average cost-effectiveness with regard to changing the intake of selected nutritional variables can be improved by 10–30 per cent if taxes/subsidies are targeted against these nutrients, compared with targeting selected food categories. Finally, the paper raises a range of issues, which need to be investigated further, before firm conclusions about the suitability of economic instruments in nutrition policy can be drawn.

An investment equation is specified to examine the relationship between defense spending and investment. The estimation results indicate that there is a significant negative effect of defense spending on investment. A simple Harrod-Domar growth relationship is used to estimate the effect of the increase in defense spending on economic growth. This analysis suggests that between 1996 and 2006, the opportunity cost of the conflict in terms of lost output has been about 3 percent of Nepal’s current GDP.

The reduction of disposable income has its consequences on patients’ ability to afford their medication. The aim of the study is to evaluate the cost of treatment for patients with COPD and the influence of the financial crisis to the patients.Methods: Data were collected from 189 patients (male: 178, mean age: 70.1±8.4 who visited the outpatient department of University Hospital of Larissa in 2014 and 2015. The pharmacological cost of treatment was calculated based on national pharmaceutical formulary prices.Results: COPD patients were classified into four stages according to Global Initiative for Chronic Obstructive Lung Disease (GOLD: 7.4% were in stage I, 43.4% in stage II, 34.4% in stage III, and 14.8% in stage IV. Patients were graded as per GOLD as follows: 18% as grade A, 14.3% as B, 23.3% as C, and 44.4% as D. The annual cost of COPD maintenance treatment per patient was €952.92 (±398.01, of which €239.91 were patients’ expenses. The annual treatment cost for stable disease ranged from €615.44 to €1302.03 depending on disease stages (GOLD stages I–IV and from €715.01 to €1101.05 depending on GOLD grades (grades A–D. The cost of maintenance medication was statistically and significantly higher for patients with advanced disease (GOLD stages III–IV and for patients at high risk (GOLD grades C–D [P=0.000].Conclusion: The pharmacological cost of treatment for COPD patients seems to be considerably high, in all disease stages. As the average income is decreased, patients face difficulties to afford inhaled medication. Keywords

  15. Integrated modeling of software cost and quality

    1994-01-01

    In modeling the cost and quality of software systems, the relationship between cost and quality must be considered. This explicit relationship is dictated by the criticality of the software being developed. The balance between cost and quality is a viable software engineering trade-off throughout the life cycle. Therefore, the ability to accurately estimate the cost and quality of software systems is essential to providing reliable software on time and within budget. Software cost models relate the product error rate to the percent of the project labor that is required for independent verification and validation. The criticality of the software determines which cost model is used to estimate the labor required to develop the software. Software quality models yield an expected error discovery rate based on the software size, criticality, software development environment, and the level of competence of the project and the developers with respect to the processes being employed

    Full Text Available The article analyses models and mechanisms of Russia's participation in integration processes in Post-Soviet space in recent years. The article examines the model of integration of Customs Union Common Economic Space Eurasian Economic Union and particular mechanisms of its realization. It also examines key challenges to further development of integration in the frameworks of Eurasian Economic Union including exhausting of short-term and medium-term integration effects against a background of low level of economic cooperation and the lack of effective mechanism of interest coordination and decisionmaking similar to qualified majority. It concludes that deterioration of mutual trade dynamics in Customs Union is determined by fundamental factors, first of all, exhausting of medium-term integration effects which lead to extension of mutual trade immediately after Customs Union creation but do not change its qualitative characteristics in long-term outlook. The author shows an absence of significant long-term integration effects which were based on increase of domestic market capacity due to a modification of economic structure. It is founded that appearance of such long-term integration effects is possible only in the context of coalescence of national economies at the microlevel based on development of system of communications between enterprises including intrasectoral industrial cooperation. The article also analyses results of realization of Russia's strategy of interaction with states beyond Eurasian Economic Union based on open regionalism concept. The paper presents recommendation on perfection of tools of integration in and outside Eurasian Economic Union. In particular, creation of system of decentralized organizations is proposed, for the implementation of specific cooperation projects in selected areas, taking into account the multiplier effect of such a "point-aimed" action/

    A statistically principled way of conducting brain network analysis is still lacking. Comparison of different populations of brain networks is hard because topology is inherently dependent on wiring cost, where cost is defined as the number of edges in an unweighted graph. In this paper, we evaluate the benefits and limitations associated with using cost-integrated topological metrics. Our focus is on comparing populations of weighted undirected graphs that differ in mean association weight, using global efficiency. Our key result shows that integrating over cost is equivalent to controlling for any monotonic transformation of the weight set of a weighted graph. That is, when integrating over cost, we eliminate the differences in topology that may be due to a monotonic transformation of the weight set. Our result holds for any unweighted topological measure, and for any choice of distribution over cost levels. Cost-integration is therefore helpful in disentangling differences in cost from differences in topology. By contrast, we show that the use of the weighted version of a topological metric is generally not a valid approach to this problem. Indeed, we prove that, under weak conditions, the use of the weighted version of global efficiency is equivalent to simply comparing weighted costs. Thus, we recommend the reporting of (i) differences in weighted costs and (ii) differences in cost-integrated topological measures with respect to different distributions over the cost domain. We demonstrate the application of these techniques in a re-analysis of an fMRI working memory task. We also provide a Monte Carlo method for approximating cost-integrated topological measures. Finally, we discuss the limitations of integrating topology over cost, which may pose problems when some weights are zero, when multiplicities exist in the ranks of the weights, and when one expects subtle cost-dependent topological differences, which could be masked by cost-integration.

    1991-01-01

    Oxygen is the most commonly discussed lunar resource. It will certainly not be the easiest to retrieve, but oxygen's fundamental place in propulsion and life support guarantees it continued attention as a prime candidate for early in situ resource utilization (ISRU). The findings are reviewed of recent investigation, sponsored by NASA-Ames, into the kinds of technologies, equipment, and scenarios (the engineering and operations costs) that will be required even to initiate lunar oxygen production. The infrastructure necessary to surround and support a viable oxygen-processing operation is explained. Selected details are used to illustrate the depth of technology challenges, extent of operations burdens, and complexity of decision linkages. Basic assumptions, and resulting timelines and mass manifests, are listed. These findings are combined with state-of-the-art knowledge of lunar and Mars propulsion options in simple economic input/output and internal-rate-of-return models, to compare production costs with performance benefits. Implications for three realistic scales of exploration architecture - expeditionary, aggressive science, and industrialization/settlement - are discussed. Conclusions are reached regarding the contextual conditions within which production of lunar oxygen (LLOX) is a reasonable activity. LLOX appears less useful for Mars missions than previously hoped. Its economical use in low Earth orbit hinges on production of lunar hydrogen as well. LLOX shows promise for lunar ascent/descent use, but that depends strongly on the plant mass required.

    Facing tight resource constraints, conservation organizations must allocate funds available for habitat protection as effectively as possible. Often, they combine spatially referenced economic and biodiversity data to prioritize land for protection. We tested how sensitive these prioritizations could be to differences in the spatial grain of these data by demonstrating how the conclusion of a classic debate in conservation planning between cost and benefit targeting was altered based on the available information. As a case study, we determined parcel-level acquisition costs and biodiversity benefits of land transactions recently undertaken by a nonprofit conservation organization that seeks to protect forests in the eastern United States. Then, we used hypothetical conservation plans to simulate the types of ex ante priorities that an organization could use to prioritize areas for protection. We found the apparent effectiveness of cost and benefit targeting depended on the spatial grain of the data used when prioritizing parcels based on local species richness. However, when accounting for complementarity, benefit targeting consistently was more efficient than a cost targeting strategy regardless of the spatial grain of the data involved. More pertinently for other studies, we found that combining data collected over different spatial grains inflated the apparent effectiveness of a cost targeting strategy and led to overestimation of the efficiency gain offered by adopting a more integrative return-on-investment approach. © 2014 Society for Conservation Biology.

  4. A case study: The economic cost of net metering in Maryland: Who bears the economic burden?

    1999-01-01

    The Maryland legislature approved net-metering legislation for residential consumer generators with photovoltaic systems during 1997. Before the legislation passed, the Maryland Energy Administration (MEA) examined its potential economic impact on both the affected utilities and consumer ratepayers--with and without net-metered PV systems. The MEA discovered that the impact on the affected utility is minimal when the net-metered PV capacity is limited to a small percentage of utility peak load. The analysis also determined that the cost burden on other customers under a net-metered scenario is likewise limited. For Maryland's largest investor-owned utility, the maximum amount of any cross-subsidy (or cost) on a per customer basis is 46 cents annually. Furthermore, their analysis showed that when distribution system savings and environmental externalities are incorporated, net-metered customers may actually subsidize other utility customers. The MEA analysis also determined that about 50% of the value of the energy produced is lost if net metering is not available to those customers with grid tied PV systems. Over the long term, most if not all of any potential cost is borne by other residential customers, not utility shareholders. Finally, the additional cost burden to the utility under net metering--compensating the consumer at the retail rate versus the avoided cost rate--is less than expected when one considers the administrative costs associated with a dual-metered billing approach

    The burden of illness that can be attributed to osteoarthritis is considerable and ever increasing. The aim of this systematic review is to analyze currently available data derived from cost-of-illness studies on the healthcare and non-healthcare costs of osteoarthritis. PubMed, Index Medicus Español (IME), and the Spanish Database of Health Sciences [Índice Bibliográfico Español en Ciencias de la Salud (IBECS)] were searched up to the end of April 2013. This study adhered to the PRISMA guidelines. Articles were reviewed and the study quality assessed by two independent investigators with consensus resolution of discrepancies. We identified 39 studies that investigated the socio-economic cost of osteoarthritis. Only nine studies took a social perspective. Rather than estimating the incremental cost of osteoarthritis, nine studies estimated the total cost of treating patients with osteoarthritis without a control for comorbidity. The other 30 studies determined the incremental cost with or without a control group. Only nine studies assessed a comprehensive list of healthcare resources. The annual incremental healthcare costs of generalized osteoarthritis ranged from €705 to €19,715. The annual incremental non-healthcare-related costs of generalized osteoarthritis ranged from €432 to €11,956. The study concludes that the social cost of osteoarthritis could be between 0.25% and 0.50% of a country׳s GDP. This should be considered in order to foster studies that take into account both healthcare and non-healthcare costs. Copyright © 2014 Elsevier Inc. All rights reserved.

    2007-01-01

    Full Text Available This paper examines the effects of regional economic integration in Europe, especially the North-North and North-South integration patterns, and how the benefits and costs of integration are divided between countries. Outcomes depend on: comparative advantages, factor endowments, factor intensities, competitive advantages, FDI flows, transfers of technology, knowledge spillovers, economies of scale, transport costs, industry/GDP ratios, and agglomeration forces. The North-North integration between high income countries tends to lead to convergence of country incomes. Contrary, the South-South integration between low income countries causes divergence. Low income countries are likely to be better served by the North-South integration.

  8. The net cost of biofuels in Thailand. An economic analysis

    2011-01-01

    Biofuels are expected to represent a growing portion of liquid fuel consumption in Thailand due to environmental and social considerations in conjunction with policy goals supporting their domestic production and consumption. This paper reviews the economic costs associated with biofuel policy implementation in Thailand in the short term target year of 2011. Internal (production) and external (environmental, social, etc.) costs and benefits are evaluated, and, where possible, monetized. Domestic production of biofuel is calculated to be 9.5 billion THB (317 million USD) more expensive than importing the equivalent amount of petroleum. The environmental benefits from GHG savings as well as losses due to increased ground level ozone formation and government expenditure to support the biofuel industry yield a total 'net cost' of 8.6 billion THB or 121 THB (4.04 USD) per capita for the year 2011. This result is contextualized with the (non-monetized) consideration that although biofuels are somewhat more expensive in the short term, their domestic production allows virtually all of the money to stay within the Thai economy as opposed to being sent abroad. This fact, coupled with significant uncertainty in future petroleum prices, could strongly influence the direction of Thai policy with respect to biofuels. (author)

    2008-04-01

    The mandate to increase endangered salmon populations in the Columbia River Basin of North America has created a complex, controversial resource-management issue. We constructed an integrated assessment model as a tool for analyzing biological-economic trade-offs in recovery of Snake River spring- and summer-run chinook salmon (Oncorhynchus tshawytscha). We merged 3 frameworks: a salmon-passage model to predict migration and survival of smolts; an age-structured matrix model to predict long-term population growth rates of salmon stocks; and a cost-effectiveness analysis to determine a set of least-cost management alternatives for achieving particular population growth rates. We assessed 6 individual salmon-management measures and 76 management alternatives composed of one or more measures. To reflect uncertainty, results were derived for different assumptions of effectiveness of smolt transport around dams. Removal of an estuarine predator, the Caspian Tern (Sterna caspia), was cost-effective and generally increased long-term population growth rates regardless of transport effectiveness. Elimination of adult salmon harvest had a similar effect over a range of its cost estimates. The specific management alternatives in the cost-effective set depended on assumptions about transport effectiveness. On the basis of recent estimates of smolt transport effectiveness, alternatives that discontinued transportation or breached dams were prevalent in the cost-effective set, whereas alternatives that maximized transportation dominated if transport effectiveness was relatively high. More generally, the analysis eliminated 80-90% of management alternatives from the cost-effective set. Application of our results to salmon management is limited by data availability and model assumptions, but these limitations can help guide research that addresses critical uncertainties and information. Our results thus demonstrate that linking biology and economics through integrated models can

  10. Economics of mycotoxins: evaluating costs to society and cost-effectiveness of interventions.

    Science.gov (United States)

    2012-01-01

    The economic impacts of mycotoxins to human society can be thought of in two ways: (i) the direct market costs associated with lost trade or reduced revenues due to contaminated food or feed, and (ii) the human health losses from adverse effects associated with mycotoxin consumption. Losses related to markets occur within systems in which mycotoxins are being monitored in the food and feed supply. Food that has mycotoxin levels above a particular maximum allowable level is either rejected outright for sale or sold at a lower price for a different use. Such transactions can take place at local levels or at the level of trade among countries. Sometimes this can result in heavy economic losses for food producers, but the benefit of such monitoring systems is a lower risk of mycotoxins in the food supply. Losses related to health occur when mycotoxins are present in food at levels that can cause illness. In developed countries, such losses are often measured in terms of cost of illness; around the world, such losses are more frequently measured in terms of disability-adjusted life years (DALYs). It is also useful to assess the economics of interventions to reduce mycotoxins and their attendant health effects; the relative effectiveness of public health interventions can be assessed by estimating quality-adjusted life years (QALYs) associated with each intervention. Cost-effectiveness assessment can be conducted to compare the cost of implementing the intervention with the resulting benefits, in terms of either improved markets or improved human health. Aside from cost-effectiveness, however, it is also important to assess the technical feasibility of interventions, particularly in low-income countries, where funds and infrastructures are limited.

    Barth, Ruediger; Weber, Christoph; Swider, Derk J.

    2008-01-01

    This article focuses on the distribution of costs induced by the integration of electricity generation from renewable energy sources (RES-E). The treatment to distribute these costs on different market actors is crucial for its development. For this purpose, individual actors of electricity markets and several cost categories are identified. According to the defined cost structure, possible treatments to distribute the individual cost categories on different relevant actors are described. Finally, an evaluation of the cost distribution treatments based on an economic analysis is given. Economic efficiency recommends that clearly attributable (shallow) grid connection as well as (deep) grid costs are charged to the corresponding RES-E producer and that the RES-E producers are also charged the regulating power costs. However, deep grid integration costs should be updated to reflect evolving scarcities. Also regulating power costs should reflect actual scarcity and thus be symmetric and based on real-time prices, taking into account the overall system imbalance. Moreover, the time span between the closure of the spot market and actual delivery should be chosen as short as possible to enable accurate RES-E production forecasts

    An Integrated Approach to Economical, Reliable, Safe Nuclear Power Production is the latest evolution of a concept which originated with the Defense-in-Depth philosophy of the nuclear industry. As Defense-in-Depth provided a framework for viewing physical barriers and equipment redundancy, the Integrated Approach gives a framework for viewing nuclear power production in terms of functions and institutions. In the Integrated Approach, four plant Goals are defined (Normal Operation, Core and Plant Protection, Containment Integrity and Emergency Preparedness) with the attendant Functional and Institutional Classifications that support them. The Integrated Approach provides a systematic perspective that combines the economic objective of reliable power production with the safety objective of consistent, controlled plant operation

    2015-04-01

    In an era of expanding health sectors and rising costs, doctors are expected to have a working knowledge of health economics to better use resources and improve outcomes and quality of health care. This article recognizes the dearth of knowledge and application of economic analyses in medical education and clinical practice in Saudi Arabia. In particular, it highlights the desirability of knowledge of health economics in ensuring certain competencies in medical education and the rationale for inviting doctors to apply knowledge of economics in Saudi Arabia. In addition, the article discusses challenges that hinder integrating health economics into clinical practice. Furthermore, the article typifies some of the important economic phenomena that physicians need to discern. Besides, the article provides implications for incorporating economic analysis into medical education and clinical practice in Saudi Arabia. Finally, the article concludes by demonstrating how health economics can enhance doctors' knowledge and recommends the country to move towards integrating health economics into medical education and clinical practice for best practice.

    2017-01-01

    Full Text Available An exploratory study has been carried out to evaluate the cost of heat supplied by a pressurized water reactor type of nuclear reactors to thermal desalination processes. In the context of this work, simplified models have been developed to describe the thermodynamics of power conversion, the energetics of multi-effect evaporation (MED, and the costs of electricity and heat cogenerated by the dual-purpose power plant. Application of these models show that, contrary to widespread belief, (nuclear-powered MED and seawater reverse osmosis are comparable in terms of energy effectiveness. Process heat can be produced, in fact, by a relatively small increase in the core power. As fuel represents just a fraction of the cost of nuclear electricity, the increase in fuel-related expenses is expected to have limited impact on power generation economics.

    2015-01-07

    Biological control is an underlying pillar of integrated pest management, yet little focus has been placed on assigning economic value to this key ecosystem service. Setting biological control on a firm economic foundation would help to broaden its utility and adoption for sustainable crop protection. Here we discuss approaches and methods available for valuation of biological control of arthropod pests by arthropod natural enemies and summarize economic evaluations in classical, augmentative, and conservation biological control. Emphasis is placed on valuation of conservation biological control, which has received little attention. We identify some of the challenges of and opportunities for applying economics to biological control to advance integrated pest management. Interaction among diverse scientists and stakeholders will be required to measure the direct and indirect costs and benefits of biological control that will allow farmers and others to internalize the benefits that incentivize and accelerate adoption for private and public good.

  18. The economic cost of fuel price subsidies in Ghana

    Science.gov (United States)

    Ofori, Roland Oduro

    I adapt the Harberger formula for deadweight loss to develop approximations for the deadweight loss created by multiple fuel price subsidies. I also estimate the own-price, cross-price, and income elasticities of demand for gasoline and diesel in Africa. I use data on fuel prices and sales in combination with my formulas and elasticity estimates to calculate the deadweight loss of fuel price subsidies in Ghana from 2009 to 2014. I show that the average efficiency cost of the gasoline and diesel price subsidies in Ghana is 0.8% of fuel price subsidy transfers. This result stresses the futility of basing subsidy reforms on economic efficiency losses, which are relatively small due to very inelastic energy demand, and the need for such reforms to be motivated by the poor-targeting of subsidies to low-income households and the impact of subsidies on government debt-financing.

A sensitivity analysis on external costs generated by global climate changes has allowed everybody to assess how possible errors in estimating the potential impact of greenhouse gasses can affect the estimate of the economic performances of different scenarios of energetic development. On the basis of these considerations, it can be outlined a potential doubling of energy production by renewable energies in the next 10 years, with specific reference of small hydroelectric, biogass and eolic power plants [it

  20. On the Integration and Synchronization of the Economic Development

    Directory of Open Access Journals (Sweden)

    Elena Viktorovna Kurushina

    2015-12-01

    Full Text Available Modern trends are associated with the integration and globalization. Integration is an immanent property of all systems and is the result of the evolution. Integration has its positive and negative effects. The degree of the progress towards the global economy is measured by the integration level in terms of the market integration indicators and the economic convergence. The latent characteristic of the globalization as a process of a unified system creation is the synchronization assuming the coincidence of the economic development ascending and descending trends in time. The coincidence of the tempo-rhythms is studied on the basis of coefficients of the pair correlation of relative growth rates of GDP for 1995-2010 in 175 countries. The very high degree of synchronization of economic dynamics is revealed in the European Union countries and in the United States. The low level of the tempo-rhythm synchronization is registered on the territory of the CIS countries. Russia occupies 29th position in the world ranking. The study of the dependence of the economic instability in the world during the crisis of 2008-2009 on the level of the tempo-rhythm coincidence shows that the more synchronized economic dynamics is, the greater excess coefficient of the average dynamics is observed during the crisis period. In 2009 it manifested itself in a greater reduction of the GDP growth rates in the European countries relatively the average wave dynamics in the pre-crisis period. The obtained results are of interest from the perspective of the substantiation of the regional economic group creation and in the context of the measures on increasing the economic stability.

  3. Transaction Costs, the Phenomenon of the Trading House and Economic Organization

    2015-12-01

    Full Text Available The present paper contains a study of the phenomenon of company’s specific internal divisions called “trading house”. The analysis of different approaches (based on results obtained by R. Coase and O. Williamson towards the problem of impact of transaction cost on company size leads to the following conclusion: the company size mostly depends on its institutional architecture which includes specific divisions that ensure outsourcing of intergroup transaction cost. I propose to call these divisions centers of transaction cost. I suppose that the wide popularity of trading houses among companies belonging to different branches can be explained by the fact that a trading house is mostly used not as selling and purchasing division, but as a center of transaction cost that concentrates the biggest transaction cost (by its share within company’s general expenses. This reasoning leads to possibility of existence of a set of methodological principles that allow to build up an a priori model of expanding company. The process of expansion represents a series of inclusion of centers of transactions cost by the company after institutional advantages of an earlier institutional architecture disappear. This methodology allows to set up a classification between a classical company as a structure with low level of integration and frozen institutional architecture and an economic organization that represents an explicitly constructed composition including centers of transaction cost that help to extend the transformational space of an expanding company.

  4. Overcoming barriers to integrating economic analysis into risk assessment.

    Science.gov (United States)

    Hoffmann, Sandra

    2011-09-01

    Regulatory risk analysis is designed to provide decisionmakers with a clearer understanding of how policies are likely to affect risk. The systems that produce risk are biological, physical, and social and economic. As a result, risk analysis is an inherently interdisciplinary task. Yet in practice, risk analysis has been interdisciplinary in only limited ways. Risk analysis could provide more accurate assessments of risk if there were better integration of economics and other social sciences into risk assessment itself. This essay examines how discussions about risk analysis policy have influenced the roles of various disciplines in risk analysis. It explores ways in which integrated bio/physical-economic modeling could contribute to more accurate assessments of risk. It reviews examples of the kind of integrated economics-bio/physical modeling that could be used to enhance risk assessment. The essay ends with a discussion of institutional barriers to greater integration of economic modeling into risk assessment and provides suggestions on how these might be overcome. © 2011 Society for Risk Analysis.

    Currently, traditional development issues such as income inequality, depletion of natural resources, environmental pollution as well as retardation of infrastructure have occurred in China. In the future, more pressures would be imposed on China by the continuous fast development of industrialization, and with transfer of the world manufacture center to China. Sustainable development, including its economic, environmental and social elements, is a key goal of decision-makers. This paper develops a methodology on cost benefit analysis of economic growth at macroscopic level to identify issues of China's sustainability. In order to address some important issues on how to make policies to improve the quality of economic growth, the CBA framework developed in this study analyses economic-ecological-social interaction, building three accounts that reflect three dimensions of sustainable development that includes 26 sub-models in all, and finally is integrated into an index as Net Progress Proceeds (NPP). The estimation methods of these submodels, such as cost of environmental pollution, depletion of natural resources and defensive expenditures are described in detail. Based on the framework and methods, this paper examines the costs and benefits of economic growth in three aspects of economy, ecology and society. The results illustrate that NPR of China's economic growth had been negative for a long time and has just became positive since year 2000 but was quite low. Even the best was only 1.6% in 2002 (the worst was - 24.2% in 1982). Based on the comparison between three accounts, we can draw a conclusion that ecological cost is the dominant factor that affects China's NPR. The empirical results show that if no other innovative measures or policies are taken in the future the costs of growth would outweigh its benefits, resulting in un-sustainability. Basically, the long-term economic growth would be unsustainable due to increasing environmental damage and depletion of

Today, the half century experience on integration and corresponding literature issued lets us see rather two big phases (instead of five. The one would be the incipient integration, that came to enlarge the economic openess and internationalization and shaped: (i free trade area (FTA and (ii customs union; the other would be the advanced integration, in which internationalization would be replaced by the unique-common market and other two commandments would replace or just reshape the older FTA and customs union into: (iii economic convergence and (iv optimal currency area.

    2013-08-01

    The objective of the study was to integrate economic parameters into genetic selection for sow productivity, growth performance and carcass characteristics in South African Large White pigs. Simulation models for sow productivity and terminal production systems were performed based on a hypothetical 100-sow herd, to derive economic values for the economically relevant traits. The traits included in the study were number born alive (NBA), 21-day litter size (D21LS), 21-day litter weight (D21LWT), average daily gain (ADG), feed conversion ratio (FCR), age at slaughter (AGES), dressing percentage (DRESS), lean content (LEAN) and backfat thickness (BFAT). Growth of a pig was described by the Gompertz growth function, while feed intake was derived from the nutrient requirements of pigs at the respective ages. Partial budgeting and partial differentiation of the profit function were used to derive economic values, which were defined as the change in profit per unit genetic change in a given trait. The respective economic values (ZAR) were: 61.26, 38.02, 210.15, 33.34, -21.81, -68.18, 5.78, 4.69 and -1.48. These economic values indicated the direction and emphases of selection, and were sensitive to changes in feed prices and marketing prices for carcasses and maiden gilts. Economic values for NBA, D21LS, DRESS and LEAN decreased with increasing feed prices, suggesting a point where genetic improvement would be a loss, if feed prices continued to increase. The economic values for DRESS and LEAN increased as the marketing prices for carcasses increased, while the economic value for BFAT was not sensitive to changes in all prices. Reductions in economic values can be counterbalanced by simultaneous increases in marketing prices of carcasses and maiden gilts. Economic values facilitate genetic improvement by translating it to proportionate profitability. Breeders should, however, continually recalculate economic values to place the most appropriate emphases on the respective

  13. To make or buy patient safety solutions: a resource dependence and transaction cost economics perspective.

    Science.gov (United States)

    Fareed, Naleef; Mick, Stephen S

    2011-01-01

    For almost a decade, public and private organizations have pressured hospitals to improve their patient safety records. Since 2008, the Centers for Medicare & Medicaid Services has no longer been reimbursing hospitals for secondary diagnoses not reported during the point of admission. This ruling has motivated some hospitals to engage in safety-oriented programs to decrease adverse events. This study examined which hospitals may engage in patient safety solutions and whether they create these patient safety solutions within their structures or use suppliers in the market. We used a theoretical model that incorporates the key constructs of resource dependence theory and transaction cost economics theory to predict a hospital's reaction to Centers for Medicare & Medicaid Services "never event" regulations. We present propositions that speculate on how forces conceptualized from the resource dependence theory may affect adoption of patient safety innovations and, when they do, whether the adopting hospitals will do so internally or externally according to the transaction cost economics theory. On the basis of forces identified by the resource dependence theory, we predict that larger, teaching, safety net, horizontally integrated, highly interdependent, and public hospitals in concentrated, high public payer presence, competitive, and resource-rich environments will be more likely to engage in patient safety innovations. Following the logic of the transaction cost economics theory, we predict that of the hospitals that react positively to the never event regulation, most will internalize their innovations in patient safety solutions rather than approach the market, a choice that helps hospitals economize on transaction costs. This study helps hospital managers in their strategic thinking and planning in relation to current and future regulations related to patient safety. For researchers and policy analysts, our propositions provide the basis for empirical testing.

  14. Determinants and Effects of Logistics Costs in Container Ports: The Transaction Cost Economics Perspective

    Directory of Open Access Journals (Sweden)

    Hyuk-soo Cho

    2014-08-01

    Full Text Available Many countries seek to become a global logistics center linking major trading ports. They are competitively constructing container ports. The aggressive competition creates overcapacity situation in the container port sector. Massive investments are required to construct container ports with terminals, docks, storage areas and hinterlands. Nevertheless, it is not easy for container ports to have sufficient container cargo volumes to justify the massive investments. Therefore, container ports of individual countries are required to develop effective strategies to have enough traffic volumes. Based on country-level analysis, this study is designed to investigate empirically internal capabilities and external environments of logistics costs and traffic volumes in individual container ports. A theoretical foundation, the transaction cost economics (TCE is applied to support and explain empirical findings.

  19. Integrating enzyme fermentation in lignocellulosic ethanol production: life-cycle assessment and techno-economic analysis.

    Cellulase enzymes have been reported to contribute with a significant share of the total costs and greenhouse gas emissions of lignocellulosic ethanol production today. A potential future alternative to purchasing enzymes from an off-site manufacturer is to integrate enzyme and ethanol production, using microorganisms and part of the lignocellulosic material as feedstock for enzymes. This study modelled two such integrated process designs for ethanol from logging residues from spruce production, and compared it to an off-site case based on existing data regarding purchased enzymes. Greenhouse gas emissions and primary energy balances were studied in a life-cycle assessment, and cost performance in a techno-economic analysis. The base case scenario suggests that greenhouse gas emissions per MJ of ethanol could be significantly lower in the integrated cases than in the off-site case. However, the difference between the integrated and off-site cases is reduced with alternative assumptions regarding enzyme dosage and the environmental impact of the purchased enzymes. The comparison of primary energy balances did not show any significant difference between the cases. The minimum ethanol selling price, to reach break-even costs, was from 0.568 to 0.622 EUR L -1 for the integrated cases, as compared to 0.581 EUR L -1 for the off-site case. An integrated process design could reduce greenhouse gas emissions from lignocellulose-based ethanol production, and the cost of an integrated process could be comparable to purchasing enzymes produced off-site. This study focused on the environmental and economic assessment of an integrated process, and in order to strengthen the comparison to the off-site case, more detailed and updated data regarding industrial off-site enzyme production are especially important.

  20. The Integrative Dimension of the Economic Globalization in European Space

    Full Text Available We believe that globalization and its socio-economic implications of the world and world economic crisis is one of the most debated issues from several years. The publication "The Economist’’ named globalization as the most used word of the century. The most relevant dimension of globalization is the economy with the more dynamic factors: technological development, the hegemony of liberal conceptions (closely linked to the triumph of the ideology of market economy and explosive development of countries or regions. Economic globalization has manifested a series of visible effects such as: the emergence of new markets and foreign trade (interconnected at global level, the appearance of: transnational companies, multilateral agreements on trade, broadening the scope of WTO, transformation of multinational companies in transnational companies and the emergence of global economic markets. Regionally, we noticed that the trendof concentration of economic activity is more pronounced and advanced in the European continent. Expanding globalization in Europe was achieved because of the fall of communism, and the neoliberal reformation which took place in Western European countries. Events like the fall of the Berlin Wall, followed by the fall of communism eradicated many political, economic, religious or cultural barriers. There were born new relations between state and market, public and private. European Union is, in our view, a regional office ofglobalization, representing the best performing integrative system in the world (by creating free trade area, customs union, common market, the Economic and Monetary Union. In terms of the European Commission,European model is a third way towards globalization, a middle path between protectionism and uncontrolled economy. To understand why the EU is an advanced approximation of globalization, perhaps a regional model of globalization, we must first understand the link between globalization and regional

    2012-01-01

    The physics metaphor, as applied to the economics (and financial performance) of the integrated health system, seems appropriate when considered together with the nine principles of management framework provided. The nature of the integrated design enhances leaders' management potential as they consider organizational operations and strategy in the markets ahead. One question begged by this argument for the integrated design is the durability, efficiency and ultimate long-term survivability of the more "traditional" community health care delivery models, which, by design, are fragmented, internally competitive and less capital efficient. They also cannot exploit the leverage of teams, optimal access management or the pursuit of revenues made available in many forms. For those who wish to move from the traditional to the more integrated community health system designs (especially those who have not yet started the journey), the path requires: * Sufficient balance sheet capacity to fund the integration process-especially as the model requires physician practice acquisitions and electronic health record implementations * A well-prepared board13, 14 * A functional, durable and sustainable physician services enterprise design * A redesigned organizational and governance structure * Favorable internal financial incentives alignment design * Effective accountable physician leadership * Awareness that the system is not solely a funding strategy for acquired physicians, rather a fully -.. committed clinical and business model, one in which patient-centered integrated care is the core service (and not acute care hospital-based services) A willingness to create and exploit the implied and inherent potential of an integrated design and unified brand Last, it's important to remember that an integrated health system is a tool that creates a "new potential" (a physics metaphor reference, one last time). The design doesn't operate itself. Application of the management principles

The recent events manifested in the world economyshow that the underlying fundamentals of this science must be revised because they proved to be wrong. Itnotes several times, mainly due to present economic crisis, that currently the economics have no theoreticaland practical means and no tools of analysis and intervention in the economy, proving that the existing onesare exceeded and insufficient, so that the creation of an unifying principle and of some generalizing conceptsthat could systematize and forecast the current economic phenomena in the microeconomics andmacroeconomics, especially in the transnational companies field, those which are the base of the foreigndirect investment flows, should become the main objective of the new economic science.

    Wood-fired combined heat and power (CHP) plants are a proven technology for producing domestic, carbon-neutral heat and power in Nordic countries. One drawback of CHP plants is the low capacity factors due to varying heat loads. In the current economic environment, uncertainty over energy prices creates also uncertainty over investment profitability. Hydrothermal carbonization (HTC) is a promising thermochemical conversion technology for producing an improved, more versatile wood-based fuel. Integrating HTC with a CHP plant allows simplifying the HTC process and extending the CHP plant operating time. An integrated polygeneration plant producing three energy products is also less sensitive to price changes in any one product. This study compares three integration cases chosen from the previous paper, and the case of separate stand-alone plants. The best economic performance is obtained using pressurized hot water from the CHP plant boiler drum as HTC process water. This has the poorest efficiency, but allows the greatest cost reduction in the HTC process and longest CHP plant operating time. The result demonstrates the suitability of CHP plants for integration with a HTC process, and the importance of economic and operational analysis considering annual load variations in sufficient detail. - Highlights: • Integration of wood hydrothermal carbonization with a small CHP plant studied. • Operation and economics of three concepts and stand-alone plants are compared. • Sensitivity analysis is performed. • Results show technical and thermodynamic analysis inadequate and misleading alone. • Minimizing HTC investment, extending CHP operating time important for profitability.

    International Nuclear Information System (INIS)

    Wu, Z.Q.; Wang, Y.N.

    2004-01-01

    Congestion cost allocation is a very important topic in congestion management. Allocation methods based on the Aumann-Shapley value use the discrete numerical integration method, which needs to solve the incremented OPF solution many times, and as such it is not suitable for practical application to large-scale systems. The optimal solution and its sensitivity change tendency during congestion removal using a DC optimal power flow (OPF) process is analysed. A simple continuous integration method based on the sensitivity is proposed for the congestion cost allocation. The proposed sensitivity analysis method needs a smaller computation time than the method based on using the quadratic method and inner point iteration. The proposed congestion cost allocation method uses a continuous integration method rather than discrete numerical integration. The method does not need to solve the incremented OPF solutions; which allows it use in large-scale systems. The method can also be used for AC OPF congestion management. (author)

    2003-01-01

    A need for an integrated cost estimating tool for nuclear decommissioning and associated waste processing and storage facilities for Intermediate Level Waste (ILW) was defined during the authors recent MSc studies. In order to close the defined gap a prototype tool was developed using logically derived CER's and cost driver variables. The challenge in developing this was to be able to produce a model that could produce realistic cost estimates from the limited levels of historic cost data that was available for analysis. The model is an excel based tool supported by 3 point risk estimating output and is suitable for producing estimates for strategic or optional cost estimates (±30%) early in the conceptual stage of a decommissioning project. The model was validated using minimal numbers of case studies supported by expert opinion discussion. The model provides an enhanced approach for integrated decommissioning estimates which will be produced concurrently with strategic options analysis on a nuclear site

    Full Text Available The article studies both general trends and peculiar characteristics of processes of economic integration in the Great East Asia, which plays the role of one of the major centers of contemporary global development. The basic determinants and barriers for implementation of regional strategies by China, Japan, ASEAN that will influence the geo-economic policy of Ukraine not only in East Asian, but also European and Eurasian areas. Attention is focused on the basic principles of realized and potential future integration models in the "ASEAN+" format with variable composition of member states that correspond to different extents to strategic objectives of both specified key actors in the region and extra-regional states that have global and transnational interests. Extrapolation of dominant trends in the nature and dynamics of transformation processes of East Asian economic regionalization allowed forming a forecast for the longterm conservation of importance of free trade agreements in the absence of preconditions to create customs unions. At the same time it was stressed out that proper assurance of national interests of international economic relations will be based on contractual instruments at the international level, without creating institutional and legal superstructure similar to the European Union or the Eurasian Economic Union as supranational law and supranational bodies.

    The impact on system costs of including a centralized interim storage facility as part of an integrated waste management system based on multi-purpose canister (MPC) technology was assessed in analyses by Energy Resources International, Inc. A system cost savings of $1 to $2 billion occurs if the Department of Energy begins spent fuel acceptance in 1998 at a centralized interim storage facility. That is, the savings associated with decreased utility spent fuel management costs will be greater than the cost of constructing and operating a centralized interim storage facility

    Development of B C Gas Utility Limited's integrated work and cost management system was described, with emphasis on cost management without reliance on the financial systems, and standard costing and operational side benefits. The objectives of the system were identified as dynamic monitoring and control, and local empowerment. The concept underlying the two systems was explained in detail. In the case of the work management system the ability to manage all work in operations areas was stressed, along with its universal availability. Other benefits expected included improved resource utilization, improved productivity, better control of cost, improved revenue generation, superior customer service, a simplified financial system, and improved employee motivation through empowerment

    United Engineers and Constructors (UE and C) and the Babcock and Wilcox Company (B and W) have performed several studies over the last eight years related to small integral pressurized water reactors. These reactors include the 365 MWt (100 MWe) Consolidated Nuclear Steam Generator (CNSG) and the 1200 MWt Consolidated Nuclear Steam System (CNSS). The studies, mostly performed under contract to the Oak Ridge National Laboratory, have led to a 1250 MWt (400 MWe) Consolidated Nuclear Steam System (CNSS) plant concept, with unique design and cost features. This report contains an update of earlier studies of the CNSS reactor and balance-of-plant concept design, capital costs, and multi-unit plant economics incorporating recent design developments, improvements, and post-TMI-2 upgrades. The economic evaluation compares the total system economic impact of a phased, three stage 400 MWe CNSS implementation program, i.e., a three-unit station, to the installation of a single 1200 MWe Pressurized Water Reactor (PWR) into a typical USA utility system.

    Jiang, Yu; Dinar, Ariel; Hellegers, Petra

    2018-04-01

    We have developed a social optimization model that integrates the financial and ecological costs associated with wastewater treatment and ecosystem damage. The social optimal abatement level of water pollution is determined by finding the trade-off between the cost of pollution control and its resulting ecosystem damage. The model is applied to data from the Lake Taihu region in China to demonstrate this trade-off. A wastewater treatment cost function is estimated with a sizable sample from China, and an ecological damage cost function is estimated following an ecosystem service valuation framework. Results show that the wastewater treatment cost function has economies of scale in facility capacity, and diseconomies in pollutant removal efficiency. Results also show that a low value of the ecosystem service will lead to serious ecological damage. One important policy implication is that the assimilative capacity of the lake should be enhanced by forbidding over extraction of water from the lake. It is also suggested that more work should be done to improve the accuracy of the economic valuation. Copyright © 2018 Elsevier Ltd. All rights reserved.

  1. Integrated environmental policy: A review of economic analysis.

    Science.gov (United States)

    Wiesmeth, Hans; Häckl, Dennis

    2017-04-01

    Holistic environmental policies, which emerged from a mere combination of technical activities in waste management some 40 years ago, constitute the most advanced level of environmental policies. These approaches to environmental policy, among them the policies in integrated waste management, attempt to guide economic agents to an environment-friendly behaviour. Nevertheless, current holistic policies in waste management, including policies on one-way drinks containers and waste electrical and electronic equipment, and implementations of extended producer responsibility with further applications to waste electrical and electronic equipment, reveal more or less severe deficiencies - despite some positive examples. This article relates these policy failures, which are not necessarily the result of an insufficient compliance with the regulations, to missing constitutive elements of what is going to be called an 'integrated environmental policy'. This article therefore investigates - mostly from a practical point of view - constitutive elements, which are necessary for a holistic policy to serve as a well-functioning allocation mechanism. As these constitutive elements result from a careful 'integration' of the environmental commodities into the economic allocation problems, we refer to these policies as 'integrated environmental policies'. The article also discusses and illustrates the main steps of designing such a policy - for waste electrical and electronic equipment and a (possible) ban of Glyphosat in agriculture. As these policies are dependent on economic and political stability with environmental awareness sufficiently developed, the article addresses mostly waste management policies in highly industrialised countries.

    A photovoltaic (PV) generator was integrated onto the north facing roof of an energy efficient house in South Africa. The building integrated photovoltaic generator (BIPV) supplies power to the household loads and the grid and is also the roof facade. This paper presents an economic evaluation of the viability of the BIPV system using methods of investment analysis. The capital cost and life cycle cost of energy were found to be ZAR 52 631-58/kWp and ZAR 1-94/kWh respectively. The payback period was 8 years and adjusted internal rate of return 9.3%. Parametric sensitivity analysis revealed that a 50% decrease in module price results in a 29% reduction in life cycle cost of energy and more than 50% reduction in payback period.

    coal-fired power plants and that with improved control technology sulfur emissions were equivalent to 0.5% sulfur coal (12500 Btu/lb.), additional estimated deaths were 3,600-36,000 annually from air pollution, 800 additional accidental deaths for transport of coal, and 40 additional deaths by mining. Under this same set of assumptions, it turns out that a nationwide nuclear moratorium could cost the U.S. the one-time equivalent of about 300 billion dollars. This can also be expressed as a recurring annual expense over the next 20-40 years of $150 per person or $600 for a family of four. Three hundred billion dollars is an enormous sum for insurance against nuclear disasters that have extremely low probabilities. Both on economic and health grounds, we question whether this type of disaster insurance is worth buying

    2015-10-01

    Full Text Available This paper tries to investigate whether there exist international integrated markets among East Asian economies, by employing the Generalized Purchasing Power Parity (G-PPP model, then, it would help to suggest whether the East Asian region is the Optimum Currency Area (OCA or not. The empirical results in this paper suggest that holding the G-PPP among nine Asian countries (China, Indonesia, Japan, Korea, Malaysia, the Philippines, Singapore, Thailand and Vietnam becomes more applicable in 2000–2013 than of that in 1984–1997. In the period of “globalization,” which is characterized by expansion of world trade, increase of international capital flows, and development of information and communications technologies, Asian economic development has been promoting not only economic integrations but also constructing the stable linkages of real exchange rates. Therefore, it would help to adopt regional coordination for monetary policies to assure the feasibility of a possible monetary union.

    1983-01-01

    The economic competitiveness of fuel cell onsite integrated energy systems (OS/IES) in residential and commercial buildings is examined. The analysis is carried out for three different buildings with each building assumed to be at three geographic locations spanning a range of climatic conditions. Numerous design options and operating strategies are evaluated and two economic criteria are used to measure economic performance. In general the results show that fuel cell OS/IES's are competitive in most regions of the country if the OS/IES is properly designed. The preferred design is grid connected, makes effective use of the fuel cell's thermal output, and has a fuel cell powerplant sized for the building's base electrical load.

    Full Text Available The Balkans region (also known as the „Powder keg of Europe” has always been an European question, a Western question, as underlined by Arnold Toynbee, in 1922. At present, European Union is confronted with the fifth enlargement, also known as the “post-conflict” enlargement – the integration of Balkan states. Bulgaria joined European Union in 2007. Croatia signed the Accession Treaty in 2011 and is expected to become an EU member in 2013. The other countries encounter in different stages of European integration. However, this process presents several challenges and dilemmas, either for European Union, or for the Balkan enclave. The main challenge in the case of this enlargement is to reconcile the nation-state building and the European integration. From the economic point of view, the Balkans region is underdeveloped. Several factors determined this stance of the region: the poor endowment in terms of natural resources, the political situation over the centuries (the military conflicts – impeding the economic development, the cultural factors. At present, the region is confronted with the consequences of the worst economic and financial crisis o global economy since the end of World War II.

    The Fort Collins Science Center's Social and Economic Analysis Branch provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and natural science in the context of human–natural resource interactions. Our research provides scientific understanding and support for the management and conservation of our natural resources in support of multiple agency missions. We focus on meeting the scientific needs of the Department of the Interior natural resource management bureaus in addition to fostering partnerships with other Federal and State managers to protect, restore, and enhance our environment. The Social and Economic Analysis Branch has an interdisciplinary group of scientists whose primary functions are to conduct both theoretical and applied social science research, provide technical assistance, and offer training to support the development of skills in natural resource management activities. Management and research issues associated with human-resource interactions typically occur in a unique context and require knowledge of both natural and social sciences, along with the skill to integrate multiple science disciplines. In response to these challenging contexts, Social and Economic Analysis Branch researchers apply a wide variety of social science concepts and methods which complement our rangeland/agricultural, wildlife, ecology, and biology capabilities. The goal of the Social and Economic Analysis Branch's research is to enhance natural-resource management, agency functions, policies, and decisionmaking.

    Economic evidence is influential in health technology assessment world-wide. Clinical Practice Guidelines (CPG) can enable economists to include economic information on health care provision. Application of economic evidence in CPGs, and its integration into clinical practice and national decision making is hampered by objections from professions, paucity of economic evidence or lack of policy commitment. The use of state-of-art economic methodologies will improve this. Economic evidence can be graded by 'checklists' to establish the best evidence for decision making given methodological rigor. New economic evaluation checklists, Multi-Criteria Decision Analyses (MCDA) and other decision criteria enable health economists to impact on decision making world-wide. We analyse the methodologies for integrating economic evidence into CPG agencies globally, including the Agency of Health Research and Quality (AHRQ) in the USA, National Health and Medical Research Council (NHMRC) and Australian political reforms. The Guidelines and Economists Network International (GENI) Board members from Australia, UK, Canada and Denmark presented the findings at the conference of the International Health Economists Association (IHEA) and we report conclusions and developments since. The Consolidated Guidelines for the Reporting of Economic Evaluations (CHEERS) 24 item check list can be used by AHRQ, NHMRC, other CPG and health organisations, in conjunction with the Drummond ten-point check list and a questionnaire that scores that checklist for grading studies, when assessing economic evidence. Cost-effectiveness Analysis (CEA) thresholds, opportunity cost and willingness-to-pay (WTP) are crucial issues for decision rules in CEA generally, including end-of-life therapies. Limitations of inter-rater reliability in checklists can be addressed by including more than one assessor to reach a consensus, especially when impacting on treatment decisions. We identify priority areas to generate

    Full Text Available The integration of wind power into power grid will bring some impacts on the multiple subjects of electric power system. Economic impacts of wind power integration on multiple subjects of China’s electric power system were quantitatively assessed from Quasi-public goods property perspective in this paper. Firstly, the Quasi-public goods property of transmission services provided by power grid corporations was elaborated. Secondly, the multiple subjects of China’s electric power system, which include electricity generation enterprises (EGEs, power grid corporations (PGCs, electricity consumers (ECs, and environment, were detailed analyzed. Thirdly, based on the OPF-based nodal price model and transmission service cost allocation model, the economic impact assessment model of wind power integration was built from Quasi-public goods property perspective. Then, the IEEE-24 bus system employed in this paper was introduced according to current status of China’s electric power system, and the modeling of wind turbine was also introduced. Finally, the simulation analysis was performed, and the economic impacts of wind power integration on EGEs, PGCs, ECs and Environment were calculated. The results indicate, from Quasi-public goods property perspective, the wind power integration will bring positive impacts on EGEs, PGCs and Environment, while negative impacts on ECs. The findings can provide references for power system managers, energy planners, and policy makers.

  15. Solid waste integrated cost analysis model: 1991 project year report

    Energy Technology Data Exchange (ETDEWEB)

    1991-01-01

    The purpose of the City of Houston's 1991 Solid Waste Integrated Cost Analysis Model (SWICAM) project was to continue the development of a computerized cost analysis model. This model is to provide solid waste managers with tool to evaluate the dollar cost of real or hypothetical solid waste management choices. Those choices have become complicated by the implementation of Subtitle D of the Resources Conservation and Recovery Act (RCRA) and the EPA's Integrated Approach to managing municipal solid waste;. that is, minimize generation, maximize recycling, reduce volume (incinerate), and then bury (landfill) only the remainder. Implementation of an integrated solid waste management system involving all or some of the options of recycling, waste to energy, composting, and landfilling is extremely complicated. Factors such as hauling distances, markets, and prices for recyclable, costs and benefits of transfer stations, and material recovery facilities must all be considered. A jurisdiction must determine the cost impacts of implementing a number of various possibilities for managing, handling, processing, and disposing of waste. SWICAM employs a single Lotus 123 spreadsheet to enable a jurisdiction to predict or assess the costs of its waste management system. It allows the user to select his own process flow for waste material and to manipulate the model to include as few or as many options as he or she chooses. The model will calculate the estimated cost for those choices selected. The user can then change the model to include or exclude waste stream components, until the mix of choices suits the user. Graphs can be produced as a visual communication aid in presenting the results of the cost analysis. SWICAM also allows future cost projections to be made.

    This article reviews psychology and behavioral economic approaches to HIV prevention, and examines the integration and application of these approaches in conditional economic incentive (CEI) programs for reducing HIV risk behavior. We discuss the history of HIV prevention approaches, highlighting the important insights and limitations of psychological theories. We provide an overview of the theoretical tenets of behavioral economics that are relevant to HIV prevention, and utilize CEIs as an illustrative example of how traditional psychological theories and behavioral economics can be combined into new approaches for HIV prevention. Behavioral economic interventions can complement psychological frameworks for reducing HIV risk by introducing unique theoretical understandings about the conditions under which risky decisions are amenable to intervention. Findings from illustrative CEI programs show mixed but generally promising effects of economic interventions on HIV and sexually transmitted infection (STI) prevalence, HIV testing, HIV medication adherence, and drug use. CEI programs can complement psychological interventions for HIV prevention and behavioral risk reduction. To maximize program effectiveness, CEI programs must be designed according to contextual and population-specific factors that may determine intervention applicability and success.

    2008-01-01

    Decommissioning cost of a nuclear power plant includes the costs related with dismantling a nuclear power plant, disposal of a spent fuel and of a low/medium radioactive waste. The decommissioning cost is different from the other expenditures in that it is occurred after the reactor finishes its commercial operation. In this respect, the electricity act was enforced to secure provisions for decommissioning a nuclear power plant during its commercial operation. The purpose of this study is to provide economic evaluation and economic cost for a decommissioning when the cost of a decommissioning is provided as one of input to the national electricity plan. Therefore, this study does not deal with whether the estimated amount of a decommissioning cost is just or not. This study focuses how to transfer the estimated decommissioning cost given in the electricity act to the economic cost, which can be used in the national electricity plan

  1. [Macro-economic calculation of spending versus micro-economic follow-up of costs of breast cancer].

    Borella, L; Paraponaris, A

    2002-12-01

    In the healthcare field, the ability to make economic forecasts requires knowledge of the costs of caring for major diseases. In the case of a semi-chronic condition like cancer, this cost covers all the episodes of care associated with a patient. An evaluation of a macro-economic method of calculating costs for treating non-metastatic cancer, covering all hospital episodes, is proposed. This method is based entirely on the use of annual hospital activity databases, linked to data concerning the incidence of cancer. It allows us to obtain the global cost of care for a neoplasm of a particular site, without the need to reconstruct the whole care pathway of the patients. The model was assessed by comparing it's own results, in the particular case of breast cancer to those issuing from a micro-economic follow-up of 115 patients. Data for macro-economic calculation are extracted from the national French hospital database for the year 1999 and from cancer incidence data. The prospective study was done in 1995, in a comprehensive cancer centre. Macro-economic calculation leads to a cost of 14,555 Euro, for primary breast cancer. Prospective follow-up showed a cost of 14,350 Euro (data corrected, 1999 value). With a difference of 1%, there was a clear cohesion of the two results, while a higher level of divergence was noticed (from 1 to 15%) in the comparison between therapeutic techniques. Accuracy and reliability of results were evaluated. This method may be extended to all types of neoplasms. This method cannot be used instead of follow-up studies, for cost-efficacy or cost-severity analysis, but may be interesting beyond economic forecasts, in the field of payment per pathology.

    Integration between quality and costing system is very crucial in order to achieve an accurate product cost and profit. Current practice by most of remanufacturers, there are still lacking on optimization during the remanufacturing process which contributed to incorrect variables consideration to the costing system. Meanwhile, traditional costing accounting being practice has distortion in the cost unit which lead to inaccurate cost of product. The aim of this work is to identify the critical and non-critical variables during remanufacturing process using Mahalanobis-Taguchi System and simultaneously estimate the cost using Activity Based Costing method. The orthogonal array was applied to indicate the contribution of variables in the factorial effect graph and the critical variables were considered with overhead costs that are actually demanding the activities. This work improved the quality inspection together with costing system to produce an accurate profitability information. As a result, the cost per unit of remanufactured crankshaft of MAN engine model with 5 critical crankpins is MYR609.50 while Detroit engine model with 4 critical crankpins is MYR1254.80. The significant of output demonstrated through promoting green by reducing re-melting process of damaged parts to ensure consistent benefit of return cores.

  5. The promise--and peril--of integrated cost systems.

    Recent advances in managerial accounting have helped executives get the information they need to make good strategic decisions. But today's enterprise resource planning systems promise even greater benefits--the chance to integrate activity-based costing, operational-control, and financial reporting systems. But managers need to approach integration very thoughtfully, or they could end up with a system that drives decision making in the wrong direction. Operational-control and ABC systems have fundamentally different purposes. Their requirements for accuracy, timeliness, and aggregation are so different that no single, fully integrated approach can be adequate for both purposes. If an integrated system used real-time cost data instead of standard rates in its ABC subsystem, for example, the result would be dangerously distorted messages about individual product profitability--and that's precisely the problem ABC systems were originally designed to address. Proper linkage and feedback between the two systems is possible, however. Through activity-based budgeting, the ABC system is linked directly to operations control: managers can determine the supply and practical capacity of resources in forthcoming periods. Linking operational control to ABC is also possible. The activity-based portion of an operational control system collects information that, while it mustn't be fed directly into the activity-based strategic cost system, can be extremely useful once it's been properly analyzed. Finally, ABC and operational control can be linked to financial reporting to generate cost of goods sold and inventory valuations--but again, with precautions.

    This paper describes the outline of integrated energy economic model and calculated result concerning the outlook of energy and carbon dioxide emissions in Japan to 2050. The energy model developed in this paper is integrated one which consistently combines econometric model endogenously generating socio-economic outlook and bottom-up type technology model, MARKAL, identifying cost-minimizing optimal mix of various energy technologies. In reference scenario which imposes no carbon emissions constraint, CO 2 emission in 2050 will decrease by approximately 40% from the level of emissions in 2005. In carbon-constraints scenario, imposing emissions cap of 60% reduction by 2050 from the emissions in 2005, natural gas-fired power plant equipped with CCS and renewable energy are expected to expand its portion in power generation mix. In transportation sector on this scenario, clean energy vehicles such as electric vehicle (EV) and hydrogen fuel cell vehicle (FCV) will be deployed and contribute to mitigate CO 2 emissions.

    Full Text Available The paper examines the potential determinants of foreign direct investment inflows into the region of Eurasian Economic Union, as well as incentives for investment into other neighboring countries. In the first model, the authors test a hypothesis on country specific foreign direct investment determinants for the Eurasian Economic Union region. The results of fixed effects estimation show that gross domestic product, infrastructure development and secondary education enrollment have a positive statistically significant effect on the foreign direct investment inflows into the region. Conversely, the impact of Customs Union on foreign direct investment appeared to be negative. Furthermore, in the second model of the natural experiment, the authors empirically test the hypothesis on Customs Union’s effect on foreign direct investment while controlling for both country and time effects. The model includes evaluating the impact of the policy change on foreign investment inflows. The natural experiment outcome also points to the negative effect of Eurasian economic integration on foreign direct investment inflows. Although the countries of Eurasian Economic Union have relatively business friendly regulations, such procedures as enforcing contracts, resolving insolvencies and dealing with construction permits are time-consuming. For attracting foreign investment, it is advisable to facilitate such procedures and make the process of setting up a new business less onerous. The research can be used as an outline for further examining of Eurasian economic integration and apart from that, the study results can be applied for practical purposes of policy elaboration aimed at stimulating foreign direct investment into the Eurasian Economic Union.

    Full Text Available The objective of this paper is an effort to view the possibilities of integrated use of target costing, activity based costing and Kaizen concept in the internal value chain as the central link of the entire chain. The idea is to stimulate the company management to think about the costs, position they take in the structure of price cost and their influence on forming the sales price since it is very important to produce right product for the consumer, of desired quality and functionality but along with as low production costs as possible. It is therefore needed to construct the right design of a product and provide its production at the shortest possible time along with as low costs as possible which will impact the efficiency of the entire value chain.

    Climate change is a global problem with local climatic and economic impacts. Mitigation policies can be applied on large geographic scales, such as a carbon cap-and-trade program for the entire U.S., on medium geographic scales, such as the NOx program for the northeastern U.S., or on smaller scales, such as statewide renewable portfolio standards and local gasoline taxes. To enable study of the environmental benefits, transition costs, capitalization effects, and other consequences of mitigation policies, we are developing dynamic general equilibrium models capable of incorporating important climate impacts. This report describes the economic framework we have developed and the current Community Integrated Model of Economic and Resource Trajectories for Humankind (CIM-EARTH) instance.

    1984-01-01

    1 - Description of problem or function: ORSIM is an electric power generating system integration model which simulates the multi-year operation of a mixed power system consisting of fossil, nuclear, hydroelectric, and pumped-storage units. For any specified refueling schedule for nuclear units and future load forecast, the model determines a plan of operation for the system which attempts to minimize the total discounted operating cost over a specified study period. The analysis considers the effects of forced outages, spinning reserve operating constraints, and scheduled introduction and retirement of generating stations. The model determines a maintenance schedule for the non-nuclear stations (nuclear stations are maintained during refueling outages) and the optimum allocation of energy-fixed nuclear and hydroelectric resources. It calculates the expected energy generated by each station in the system, by period over the planning horizon, based on input or calculated incremental operating cost. It also calculates the expected loss-of- load probability and un-served energy demand for each period in the planning horizon. An optimum operating plan, designed to minimize the discounted total production cost, is then calculated, as are the costs of operating each station in the system and the discounted total production cost for the derived plan of operation. 2 - Method of solution: ORSIM searches for a particular mode of operation which, over a multi-year planning horizon, will minimize the total system operating cost of a particular electric power generation system discounted to the beginning of the planning horizon. It does this by: (a) calculating the planned maintenance outages for all units; (b) estimating the incremental discounted cost of energy produced by each station in the system for every subinterval of the planning horizon; (c) utilizing the incremental discounted costs of energy generation to calculate, via probabilistic simulation, the economic optimum

    It has become essential in policy and decision-making circles to think about the economic benefits (in addition to moral and scientific motivations) humans derive from well-functioning ecosystems. The concept of ecosystem services has been developed to address this link between ecosystems and human welfare. Since policy decisions are often evaluated through cost-benefit assessments, an economic analysis can help make ecosystem service research operational. In this paper we provide some simple economic analyses to discuss key concepts involved in formalizing ecosystem service research. These include the distinction between services and benefits, understanding the importance of marginal ecosystem changes, formalizing the idea of a safe minimum standard for ecosystem service provision, and discussing how to capture the public benefits of ecosystem services. We discuss how the integration of economic concepts and ecosystem services can provide policy and decision makers with a fuller spectrum of information for making conservation-conversion trade-offs. We include the results from a survey of the literature and a questionnaire of researchers regarding how ecosystem service research can be integrated into the policy process. We feel this discussion of economic concepts will be a practical aid for ecosystem service research to become more immediately policy relevant.

    Science.gov (United States)

    Lotus (Neumbo nucifera, Gaertn) is the most important aquatic vegetable in China, with a cultivation history of over 3000 years. The emergy, energy, material, and money flows of three lotus root cultivation modes in Wanqingsha, Nansha District, Guangzhou, China were examined using Energy Systems Language models and emergy evaluation to better understand their ecological and economic characteristics on multiple spatial and temporal scales. The natural resource foundations, economic characteristics and sustainability of these modes were evaluated and compared. The results showed that although all three modes were highly dependent on purchased emergy inputs, their potential impacts as measured by the local (ELRL) and global (ELRW) environmental loading ratios were less than 1.2 and 0.7, respectively. The lotus-fish mode was the most sustainable with its emergy index of sustainable development (EISD) 2.09 and 2.13 times that of the pure lotus and lotus-shrimp modes, respectively. All three lotus-root production modes had superior economic viability, since their Output/Input ratio ranged from 2.56 to 4.95. The results indicated that agricultural systems may have different environmental impacts and sustainability characteristics at different spatial and temporal scales, and that these impacts and characteristics can be simultaneously explored using integrated emergy and economic evaluations. This study provides some major new insights about agriculture and its potenti

    Without an equal sharing of costs and benefits of natural and human resources worldwide, imbalances and lack of human development lead to migration within and between countries. Economic integration blocks in Latin America provide a context for shared development: in Central America, in the Andean Region, and in the Southern Cone. Over the past 60 years migration policy was based on national protectionism, labor supply, and/or occupation of territory. When economic conditions changed to market economies and world markets, migration policy was redefined. Each of the economic integration blocks has developed its own strategies. The Andean Agreement on Labor Migrations was established to determine the rules for bilateral and multilateral treatment of problems. In the Southern Cone bilateral agreements have been longstanding. Multilateral efforts were recently underway within the Southern Common Market and throughout the region. The Central American Organization for Migrations has spearheaded the adoption of a multilateral strategy. All three regions have made considerable progress in the last three years in constructing multilateral policies for economic integration. Government awareness has been the primary force in these policy changes. Government has come to an understanding that clear domestic and regional migration policies were lacking and that obsolete migration practices of the 1930s did not meet the needs of the 1990s. Migration policy was considered an instrument of development. Movement of economic factors or goods was considered equally with movement of labor. Migration policies must integrate the human rights of migrants into their definitions. Methods of facilitating the movements of populations need to be constructed within the computerization and modernization of the migration administration. Legalization of illegal immigrants has occurred among a number of countries. PROCAM and PRIMCOS were action programs which aimed to integrate migration and

    A large number of offshore wind farms and interconnectors are expected to be constructed in the North Sea region over the coming decades, creating substantial opportunities for the deployment of integrated network solutions. Creating interconnected offshore grids that combine cross-border links and connections of offshore plants to shore offers multiple economic and environmental advantages for Europe's energy system. However, despite evidence that integrated solutions can be more beneficial than traditional radial connection practices, no such projects have been deployed yet. In this paper we quantify costs and benefits of integrated projects and investigate to which extent the cost-benefit sharing mechanism between participating countries can impede or encourage the development of integrated projects. Three concrete interconnection case studies in the North Sea area are analysed in detail using a national-level power system model. Model outputs are used to compute the net benefit of all involved stakeholders under different allocation schemes. Given the asymmetric distribution of costs and benefits, we recommend to consistently apply the Positive Net Benefit Differential mechanism as a starting point for negotiations on the financial closure of investments in integrated offshore infrastructure. - Highlights: • Three North Sea offshore gird case studies are analysed. • They are shown to have substantial net benefit over non-integrated network designs. • Asymmetric net benefit sharing between countries is shown to be a barrier. • Positive Net Benefit Differential method alleviates asymmetric benefits.

    The objective of this study was to examine the intervention costs of a residential community reintegration programme for patients with acquired brain injury and to compare the societal costs before and after treatment. A cost-analysis was performed identifying costs of healthcare, informal care, and productivity losses. The costs in the year before the Brain Integration Programme (BIP) were compared with the costs in the year after the BIP using the following cost categories: care consumption, caregiver support, productivity losses. Dutch guidelines were used for cost valuation. Thirty-three cases participated (72% response). Mean age was 29.8 years, 59% traumatic brain injury. The BIP costs were €68,400. The informal care and productivity losses reduced significantly after BIP (p costs per patient were €48,449. After BIP these costs were €39,773; a significant reduction (p costs after the BIP advocates the allocation of resources and, from an economic perspective, favours reimbursement of the BIP costs by healthcare insurance companies. However, this cost-analysis is limited as it does not relate costs to clinical effectiveness. :

  1. Cost-effective conservation planning: lessons from economics.

    Science.gov (United States)

    Duke, Joshua M; Dundas, Steven J; Messer, Kent D

    2013-08-15

    Economists advocate that the billions of public dollars spent on conservation be allocated to achieve the largest possible social benefit. This is "cost-effective conservation"-a process that incorporates both monetized benefits and costs. Though controversial, cost-effective conservation is poorly understood and rarely implemented by planners. Drawing from the largest publicly financed conservation programs in the United States, this paper seeks to improve the communication from economists to planners and to overcome resistance to cost-effective conservation. Fifteen practical lessons are distilled, including the negative implications of limiting selection with political constraints, using nonmonetized benefit measures or benefit indices, ignoring development risk, using incomplete cost measures, employing cost measures sequentially, and using benefit indices to capture costs. The paper highlights interrelationships between benefits and complications such as capitalization and intertemporal planning. The paper concludes by identifying the challenges at the research frontier, including incentive problems associated with adverse selection, additionality, and slippage. Copyright © 2013 Elsevier Ltd.

    Full Text Available The purpose of the paper. In our study we try to assess the causality link between a number of the international economic integration politico-economic factors, institutions and basic production factors with the growth of the economy. We form a sample of 18 post-socialist countries, including Central and Eastern Europe (CEE countries-members the European Union, and the rest of CEE non-members countries and CIS countries, who have not acquired the membership in the EU, including Ukraine. The time period of our study is 23 years, starting from 1991 – the year of independence of Ukraine till 2013 – the last year for which statistics are published for our group of a corresponding list of indicators that make up our interest. In the estimating equation we use econometric analysis panel data by least squares method with fixed effects transformation to eliminate countries’ heterogeneity. In the study we use such determinant of the institutions quality as the Index of Economic Freedom (Heritage Foundation, and we investigate various components of the Index of Economic Freedom (freedom of ownership, freedom of trade, freedom from corruption, freedom of investment. We assume that institutions towards freedom of foreign trade and reducing corruption will have a greater effect on the economy of the investigated countries. It is advisable to attach to the international economic integration politico-economic factors the indicator of foreign trade taxation as a measure of tariff barriers, international aid programs of the foreign donors and the European institutions to assess their role for the economic growth of the countries surveyed, and we take into account the capital and the labor as the basic factors of production.

    2012-08-01

    Full Text Available Cost allocation of transmission usage on the power networks is an important issue especially in the modern electricity market mechanism. In this context, all costs that have been embedded in the transmission, embedded cost, should be covered by the transmission users. This paper follows general methods, where generators are fullyresponsible to cover the embedded cost. It proposes a method to determine the cost allocation of transmission usage based on decomposition through the superposition techinique to determine power flow contributions from an integrated base case of the results of the power flow calculations of all transactions, bilateral and nonbilateral contracts. Mathematically, the applied formulations are illustrated clearly in this paper. The proposed method has been tested with 5-bus system and the results are much different compared to a few of the published methods. This is shown by the test results on the 5 bus system. The published methods produce total power flow contributions in each line is greater than the actual. And they earn total revenues approximately 11.6% greater than the embedded cost. While on the proposed method, the power flow contribu tions are equal to the actual and the revenues are equal to the embedded cost. It shows also that the proposed method gives results as expected.

    2012-01-01

    Wind and solar energy will play an important role in the decarbonization of the European electricity generation. However, high shares of these variable renewable energies (VREs) challenge the power system considerably due to their temporal fluctuations and geographical dispersion. In this paper, we systematically analyze transmission grid extensions as an integration measure for VREs in Europe. We show the effects of grid extensions for fundamental properties of the power system as a function of the penetration and mix of wind and solar energy. Backup capacity requirements and overproduction are reduced with a powerful overlay transmission grid. We determine the costs of the grid extensions in dependence of the VRE penetration and mix and find that the grid integration costs remain below 25% of the VRE investment costs for all conceivable VRE configurations. Furthermore, robust design features of future power systems in terms of grid geometry and flexibility requirements for backup technologies are identified. We apply a spatially and temporally highly resolved techno-economic model of the European power system for our analysis. - Highlights: ► Quantification of the advantages and costs of a European overlay transmission grid. ► Grid integration costs for VREs in Europe remain below 6€/MWh. ► Application of a detailed power system model to a wide parameter space.

    Full Text Available The limited operational flexibility of combined heat and power (CHP units is the main cause of wind power curtailment in the thermal-electrical power system of Northern China. Pumped hydrostorage (PHS, heat storage (HS, and electric boiler (EB are investigated as three alternative options for the promotion of wind power integration. On the basis of two linear models that determine the capacities of these three facilities required for integrating the curtailed wind power, economic evaluation in terms of investment costs and environmental benefits is presented. Analysis results show that HS requires the least investment and has a good performance of coal saving when accommodating the same amount of curtailed wind power. And EB has the greatest potential for wind power integration with the huge growth of installed capacity of wind power in the future.

    The environmental outcomes of urban form changes should couple life-cycle and behavioral assessment methods to better understand urban sustainability policy outcomes. Using Phoenix, Arizona light rail as a case study, an integrated transportation and land use life-cycle assessment (ITLU-LCA) framework is developed to assess the changes to energy consumption and air emissions from transit-oriented neighborhood designs. Residential travel, commercial travel, and building energy use are included and the framework integrates household behavior change assessment to explore the environmental and economic outcomes of policies that affect infrastructure. The results show that upfront environmental and economic investments are needed (through more energy-intense building materials for high-density structures) to produce long run benefits in reduced building energy use and automobile travel. The annualized life-cycle benefits of transit-oriented developments in Phoenix can range from 1.7 to 230 Gg CO2e depending on the aggressiveness of residential density. Midpoint impact stressors for respiratory effects and photochemical smog formation are also assessed and can be reduced by 1.2-170 Mg PM10e and 41-5200 Mg O3e annually. These benefits will come at an additional construction cost of up to $410 million resulting in a cost of avoided CO2e at $16-29 and household cost savings.

    Default values for various data provided by MACCS2(MELCOR Accident Consequence Code System Version 2) such as population, weather, food, and economic cost are far from current domestic condition. In the case of economic cost data, related default values came from MACCS and WASH-1400. KAERI (Korea Atomic Energy Research Institute) has been developed a Korean-specific level 3 PSA (Probabilistic Safety Assessment) code package based on MACCS2 to reflect domestic condition for off-site consequence analysis. To this end, we performed a study on the domestic specific technical issues for level 3 PSA, which are a dose conversion factor, food chain model, atmospheric dispersion model, and domestic-specific economic effect model. Based on the study, we developed a level 3 PSA code, so-called KOSCAMACCS2 (Korean-specific Off-Site Consequence Analysis based on MACCS2). The purpose of this paper is to introduce economic cost variable provided by KOSCA-MACCS2 and application of Korean-specific data to the related economic cost estimation with KOSCA-MACCS2. In this paper, we introduced economic cost variable provided by KOSCA-MACCS2 and suggested the application plan of Korean-specific data to the related economic cost estimation. To this end, we considered data sources for those economic cost variables to reflect Korea-specific features such as data by Statistics Korea or Bank of Korea etc. For the decontamination related variables, we applied foreign literatures to apply data, which are Extern-E and UNESCO Chernobyl Forum data. Based on the data resources we estimated data for input variables related to economic cost estimation.

    The highest barriers to wide scale implementation of vision systems have been cost. This is closely followed by the level of difficulty of putting a complete imaging system together. As anyone who has every been in the position of creating a vision system knows, the various bits and pieces supplied by the many vendors are not under any type of standardization control. In short, unless you are an expert in imaging, electrical interfacing, computers, digital signal processing, and high speed storage techniques, you will likely spend more money trying to do it yourself rather than to buy the exceedingly expensive systems available. Another alternative is making headway into the imaging market however. The growing investment in highly integrated CMOS based imagers is addressing both the cost and the system integration difficulties. This paper discusses the benefits gained from CMOS based imaging, and how these benefits are already being applied.

    Full Text Available Background: The objective of this study is to investigate whether the algorithm proposed by Manning and Mullahy, a consolidated health economics procedure, can also be used to estimate individual costs for different groups of healthcare services in the context of integrated care. Methods: A cross-sectional study focused on the population of the Baix Empordà (Catalonia-Spain for the year 2012 (N = 92,498 individuals. A set of individual cost models as a function of sex, age and morbidity burden were adjusted and individual healthcare costs were calculated using a retrospective full-costing system. The individual morbidity burden was inferred using the Clinical Risk Groups (CRG patient classification system. Results: Depending on the characteristics of the data, and according to the algorithm criteria, the choice of model was a linear model on the log of costs or a generalized linear model with a log link. We checked for goodness of fit, accuracy, linear structure and heteroscedasticity for the models obtained. Conclusion: The proposed algorithm identified a set of suitable cost models for the distinct groups of services integrated care entails. The individual morbidity burden was found to be indispensable when allocating appropriate resources to targeted individuals.

    Full Text Available Background: Determining the disease and economic burden of dengue is critical for the allocation of public health resources. Several studies have used disability-adjusted life-years (DALYs to estimate the disease burden of dengue in different regions. However, there are no published studies discussing the estimates of dengue-related economic and disease burden specifically in Taiwan. Objectives: We assessed the economic cost and disease burden of dengue infections in Taiwan for the period 1998–2014, and compared these during epidemic and non-epidemic years. Methods: We estimated the annual DALYs per million population using the disability weights for dengue fever (DF, dengue hemorrhagic fever (DHF, dengue shock syndrome (DSS, and death cases. Economic costs were estimated and divided into direct (medical costs and indirect costs (lost work days and caregiver fees. Results: For the period 1998–2014, a mean of 115.3 (range: 6.3–934.3 DALYs per million population annually were lost to dengue. In epidemic years, direct costs associated with dengue resulted mostly from hospitalization (86.09%, emergency (7.77%, outpatient (6.10%, and drug costs (0.03%. For indirect costs, lost productivity due to death (70.76% was the dominant contributor. Overall, the costs were 12.3 times higher in epidemic years than in non-epidemic years (Wilcoxon rank sum test, p < 0.05. Conclusions: This study is the first to evaluate the economic costs and disease burden of dengue infections for this period in Taiwan, and reveals significant differences in economic impact between epidemic and non-epidemic years.

    Highlights: • Hydrothermal liquefaction and concentrated solar power provide integrated biofuel technology. • Heat kinetics and energy efficiency Aspen plus modelling of CSP and HTL. • Microalgae biofuel minimum fuel sales price of $1.23/kg. - Abstract: Integration of Hydrothermal Liquefaction (HTL) of microalgae biomass with concentrated solar power thermal processing (CSP) for bio-oil production is a potential processing pathway for energy efficient generation of renewable biofuels. Solar HTL infrastructure avoids additional bolt-on components of conventional solar parabolic trough systems used for electricity production including heat transfer fluids, counter current heat exchangers, fluid transfer interconnectivity and electrical power control systems. The absence of such capital intensive additional equipment considerably reduces the production costs of solar HTL biofuels compared to electricity generation from conventional CSP power systems. An economic and market appraisal of variance and system economic resilience is presented. It is hypothesised that the combination of nutrient recycling with HTL/CSP unification has the potential for economically sustainable microalgae bio-oil production. A microalgae biofuel minimum fuel sales price of $1.23/kg has been modelled. Further experimental work would be able to validate this integrated model.

  13. Process modelling and techno-economic analysis of natural gas combined cycle integrated with calcium looping

    2016-01-01

    Full Text Available Calcium looping (CaL is promising for large-scale CO2 capture in the power generation and industrial sectors due to the cheap sorbent used and the relatively low energy penalties achieved with this process. Because of the high operating temperatures the heat utilisation is a major advantage of the process, since a significant amount of power can be generated from it. However, this increases its complexity and capital costs. Therefore, not only the energy efficiency performance is important for these cycles, but also the capital costs must be taken into account, i.e. techno-economic analyses are required in order to determine which parameters and configurations are optimal to enhance technology viability in different integration scenarios. In this study the integration scenarios of CaL cycles and natural gas combined cycles (NGCC are explored. The process models of the NGCC and CaL capture plant are developed to explore the most promising scenarios for NGCC-CaL integration with regards to efficiency penalties. Two scenarios are analysed in detail, and show that the system with heat recovery steam generator (HRSG before and after the capture plant exhibited better performance of 49.1% efficiency compared with that of 45.7% when only one HRSG is located after the capture plant. However, the techno-economic analyses showed that the more energy efficient case, with two HRSGs, implies relatively higher cost of electricity (COE, 44.1€/MWh, when compared to that of the reference plant system (33.1€/MWh. The predicted cost of CO2 avoided for the case with two HRSGS is 29.3 €/ton CO2.

    Objective To estimate the health-related economic costs attributable to smoking in China for persons aged 35 and older in 2003 and in 2008 and to compare these costs with the respective results from 2000. Methods A prevalence-based, disease-specific approach was used to estimate smoking-attributable direct and indirect economic costs. The primary data source was the 2003 and 2008 China National Health Services Survey, which contains individual participant’s smoking status, healthcare utilization, and expenditures. Results The total economic cost of smoking in China amounted to $17.1 billion in 2003 and $28.9 billion in 2008 (both measured in 2008 constant US dollars). Direct smoking-attributable healthcare costs in 2003 and 2008 were $4.2 billion and $6.2 billion, respectively. Indirect economic costs in 2003 and 2008 were $12.9 billion and $22.7 billion, respectively. Compared to 2000, the direct costs of smoking rose by 72% in 2003 and 154% in 2008, while the indirect costs of smoking rose by 170% in 2003 and 376% in 2008. Conclusion The economic burden of cigarette smoking has increased substantially in China during the past decade and is expected to continue to increase as the national economy and the price of healthcare services grow. Stronger intervention measures against smoking should be taken without delay to reduce the health and financial losses caused by smoking. PMID:21339491

    2018-01-01

    Full Text Available The article substantiates expediency of introduction of the system of economic security of enterprise on the basis of money flows. The methods proposed in the long-term period stipulate the use as sources of financing: accumulated conditional economic costs, accumulated conditional gross and net money flow; and as costs: cumulative advanced costs and the advanced value of fixed assets. The article suggests methods for calculation of: gross index of conditional yield; gross conditional income of project; gross conditional profitability; gross conditional profitability of money flow. The managerial decision on introduction of the system of economic security of enterprise in the short-term production period has been substantiated on the basis of calculations of the following indicators: gross profitability of annual depreciation; annual gross economic effect; index of conditional yield of the gross money flow; differences between the conditional gross cash flow and the depreciation deductions associated with the implementation of the enterprise’s economic security system.

    Clinical mastitis results in considerable economic losses for dairy producers and is most commonly diagnosed in early lactation. The objective of this research was to estimate the economic impact of clinical mastitis occurring during the first 30 days of lactation for a representative US dairy. A deterministic partial budget model was created to estimate direct and indirect costs per case of clinical mastitis occurring during the first 30 days of lactation. Model inputs were selected from the available literature, or when none were available, from herd data. The average case of clinical mastitis resulted in a total economic cost of $444, including $128 in direct costs and $316 in indirect costs. Direct costs included diagnostics ($10), therapeutics ($36), non-saleable milk ($25), veterinary service ($4), labor ($21), and death loss ($32). Indirect costs included future milk production loss ($125), premature culling and replacement loss ($182), and future reproductive loss ($9). Accurate decision making regarding mastitis control relies on understanding the economic impacts of clinical mastitis, especially the longer term indirect costs that represent 71% of the total cost per case of mastitis. Future milk production loss represents 28% of total cost, and future culling and replacement loss represents 41% of the total cost of a case of clinical mastitis. In contrast to older estimates, these values represent the current dairy economic climate, including milk price ($0.461/kg), feed price ($0.279/kg DM (dry matter)), and replacement costs ($2,094/head), along with the latest published estimates on the production and culling effects of clinical mastitis. This economic model is designed to be customized for specific dairy producers and their herd characteristics to better aid them in developing mastitis control strategies.

    To evaluate the cost effectiveness, cost utility, and cost-benefit of an integrated care programme compared with usual care for sick listed patients with chronic low back pain. Economic evaluation alongside a randomised controlled trial with 12 months' follow-up. Primary care (10 physiotherapy practices, one occupational health service, one occupational therapy practice) and secondary care (five hospitals) in the Netherlands, 2005-9. 134 adults aged 18-65 sick listed because of chronic low back pain: 66 were randomised to integrated care and 68 to usual care. Integrated care consisted of a workplace intervention based on participatory ergonomics, with involvement of a supervisor, and a graded activity programme based on cognitive behavioural principles. Usual care was provided by general practitioners and occupational physicians according to Dutch guidelines. The primary outcome was duration until sustainable return to work. The secondary outcome was quality adjusted life years (QALYs), measured using EuroQol. Total costs in the integrated care group (£13 165, SD £13 600) were significantly lower than in the usual care group (£18 475, SD £13 616). Cost effectiveness planes and acceptability curves showed that integrated care was cost effective compared with usual care for return to work and QALYs gained. The cost-benefit analyses showed that every £1 invested in integrated care would return an estimated £26. The net societal benefit of integrated care compared with usual care was £5744. Implementation of an integrated care programme for patients sick listed with chronic low back pain has a large potential to significantly reduce societal costs, increase effectiveness of care, improve quality of life, and improve function on a broad scale. Integrated care therefore has large gains for patients and society as well as for employers.

  2. Determining the economic cost of ICU treatment: a prospective "micro-costing" study.

    2012-02-01

    OBJECTIVE: To prospectively assess the cost of patients in an adult intensive care unit (ICU) using bottom-up costing methodology and evaluate the usefulness of "severity of illness" scores in estimating ICU cost. METHODS AND DESIGN: A prospective study costing 64 consecutive admissions over a 2-month period in a mixed medical\\/surgical ICU. RESULTS: The median daily ICU cost (interquartile range, IQR) was 2,205 euro (1,932 euro-3,073 euro), and the median total ICU cost (IQR) was 10,916 euro (4,294 euro-24,091 euro). ICU survivors had a lower median daily ICU cost at 2,164 per day, compared with 3,496 euro per day for ICU non-survivors (P = 0.08). The requirements for continuous haemodiafiltration, blood products and anti-fungal agents were associated with higher daily and overall ICU costs (P = 0.002). Each point increase in SAPS3 was associated with a 305 euro (95% CI 31 euro-579 euro) increase in total ICU cost (P = 0.029). However, SAPS3 accounted for a small proportion of the variance in this model (R (2) = 0.08), limiting its usefulness as a stand-alone predictor of cost in clinical practice. A model including haemodiafiltration, blood products and anti-fungal agents explained 54% of the variance in total ICU cost. CONCLUSION: This bottom-up costing study highlighted the considerable individual variation in costs between ICU patients and identified the major factors contributing to cost. As the requirement for expensive interventions was the main driver for ICU cost, "severity of illness" scores may not be useful as stand-alone predictors of cost in the ICU.

    Highlights: • We compare two remediation scenarios; one with resource recovery and one without. • Economic analysis includes relevant direct costs and revenues for the landfill owner. • High degrees of metal and/or combustible contents are important economic factors. • Landfill tax and the access to a CHP can have a large impact on the result. • Combining landfill mining and remediation may decrease the project cost. - Abstract: This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation. Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP. Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material

    Highlights: • We compare two remediation scenarios; one with resource recovery and one without. • Economic analysis includes relevant direct costs and revenues for the landfill owner. • High degrees of metal and/or combustible contents are important economic factors. • Landfill tax and the access to a CHP can have a large impact on the result. • Combining landfill mining and remediation may decrease the project cost. - Abstract: This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation. Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP. Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material.

    A detailed thermo-economic model combining thermodynamics with economic analysis and considering different technological alternatives for the thermochemical production of liquid fuels from lignocellulosic biomass is presented. Energetic and economic models for the production of Fischer-Tropsch fuel (FT), methanol (MeOH) and dimethyl ether (DME) by means of biomass drying with steam or flue gas, directly or indirectly heated fluidized bed or entrained flow gasification, hot or cold gas cleaning, fuel synthesis and upgrading are reviewed and developed. The process is integrated and the optimal utility system is computed. The competitiveness of the different process options is compared systematically with regard to energetic, economic and environmental considerations. At several examples, it is highlighted that process integration is a key element that allows for considerably increasing the performance by optimal utility integration and energy conversion. The performance computations of some exemplary technology scenarios of integrated plants yield overall energy efficiencies of 59.8% (crude FT-fuel), 52.5% (MeOH) and 53.5% (DME), and production costs of 89, 128 and 113 Euro MWh -1 on fuel basis. The applied process design approach allows to evaluate the economic competitiveness compared to fossil fuels, to study the influence of the biomass and electricity price and to project for different plant capacities. Process integration reveals in particular potential energy savings and waste heat valorization. Based on this work, the most promising options for the polygeneration of fuel, power and heat will be determined in a future thermo-economic optimization.

  6. Evaluating the economic cost of natural gas strategic storage restrictions

    International Nuclear Information System (INIS)

    Ejarque, Joao Miguel

    2011-01-01

    The European Commission wants to implement a single market for gas. One of the components of this market is a regulated provision for ''security of supply'' which consists of rules for the implementation and use of a given reserve stock of gas. We investigate the impact of this policy on the profitability of a storage operator, using data from Denmark and Italy. Keeping storage capacity constant, the costs of the strategic stock are around 20% of the value of the storage market for Denmark, and 16% for Italy. This cost is due to the inability to extract arbitrage profits from the captive stock. Furthermore, the strategic storage restriction induces behavior that would virtually never be replicated by a private storage operator in an unconstrained market, in particular in the first 6 months of the year when unconstrained firms empty their reservoirs much faster, suggesting the strategic restriction is unnecessarily distorting the market.

    To estimate the economic burden of coronary heart disease (CHD) in a given year (2010), including direct and indirect costs, and examine the impact of contextual and individual socio-economic (SES) predictors on the costs of CHD among adults in rural southwest China. Cross-sectional community survey. In total, 4595 adults (aged ≥18 years) participated in this study. A prevalence-based cost-of-illness approach was used to estimate the economic burden of CHD. Information on demographic characteristics of the study population and the economic consequences of CHD was obtained using a standard questionnaire. Multilevel linear regression was used to model the variation in costs of CHD. In the study population, the overall prevalence of CHD was 2.9% (3.5% for males, 2.3% for females). The total cost of CHD was estimated to be US$17 million. Inpatient hospitalizations represented the main component of direct costs of CHD, and direct costs accounted for the greatest proportion of the economic burden of CHD. Males were more likely to have a higher economic burden of CHD than females. A positive association was found between the individual's level of education and the economic burden of CHD. Residence in a higher-income community was associated with higher costs related to CHD. This study found that both contextual and individual SES were closely associated with the costs of CHD. Future strategies for CHD interventions and improved access to affordable medications to treat and control CHD should focus on less-educated individuals and communities with lower SES.

    Full Text Available Farm machinery managers often need to make complex economic decisions on machinery replacement. Repair and maintenance costs can have significant impacts on this economic decision. The farm manager must be able to predict farm machinery repair and maintenance costs. This study aimed to identify a regression model that can adequately represent the repair and maintenance costs in terms of machine age in cumulative hours of use. The regression model has the ability to predict the repair and maintenance costs for longer time periods. Therefore, it can be used for the estimation of the economic life. The study was conducted using field data collected from 11 John-Deer 955 combine harvesters used in several western provinces of Iran. It was found that power model has a better performance for the prediction of combine repair and maintenance costs. The results showed that the optimum replacement age of John-Deer 955 combine was 54300 cumulative hours.

    Over the past decade, the production of economic indices behind the CATDAT Damaging Earthquakes Database has allowed for the conversion of historical earthquake economic loss and cost events into today's terms using long-term spatio-temporal series of consumer price index (CPI), construction costs, wage indices, and GDP from 1900-2013. As part of the doctoral thesis of Daniell (2014), databases and GIS layers for a country and sub-country level have been produced for population, GDP per capita, net and gross capital stock (depreciated and non-depreciated) using studies, census information and the perpetual inventory method. In addition, a detailed study has been undertaken to collect and reproduce as many historical isoseismal maps, macroseismic intensity results and reproductions of earthquakes as possible out of the 7208 damaging events in the CATDAT database from 1900 onwards. a) The isoseismal database and population bounds from 3000+ collected damaging events were compared with the output parameters of GDP and net and gross capital stock per intensity bound and administrative unit, creating a spatial join for analysis. b) The historical costs were divided into shaking/direct ground motion effects, and secondary effects costs. The shaking costs were further divided into gross capital stock related and GDP related costs for each administrative unit, intensity bound couplet. c) Costs were then estimated based on the optimisation of the function in terms of costs vs. gross capital stock and costs vs. GDP via the regression of the function. Losses were estimated based on net capital stock, looking at the infrastructure age and value at the time of the event. This dataset was then used to develop an economic exposure for each historical earthquake in comparison with the loss recorded in the CATDAT Damaging Earthquakes Database. The production of economic fragility functions for each country was possible using a temporal regression based on the parameters of

    A harmony search (HS) algorithm was used to optimize economic dispatch (ED) in a wind energy conversion system (WECS) for power system integration. The HS algorithm was based on a stochastic random search method. System costs for the WECS system were estimated in relation to average wind speeds. The HS algorithm was implemented to optimize the ED with a simple programming procedure. The study showed that the initial parameters must be carefully selected to ensure the accuracy of the HS algorithm. The algorithm demonstrated that total costs of the WECS system were higher than costs associated with energy efficiency procedures that reduced the same amount of greenhouse gas (GHG) emissions. 7 refs,. 10 tabs., 16 figs.

  12. Economics of Renewable Energy Integration and Energy Storage via Low Load Diesel Application

    Directory of Open Access Journals (Sweden)

    James Hamilton

    2018-04-01

    Full Text Available One-quarter of the world’s population lives without access to electricity. Unfortunately, the generation technology most commonly employed to advance rural electrification, diesel generation, carries considerable commercial and ecological risks. One approach used to address both the cost and pollution of diesel generation is renewable energy (RE integration. However, to successfully integrate RE, both the stochastic nature of the RE resource and the operating characteristics of diesel generation require careful consideration. Typically, diesel generation is configured to run heavily loaded, achieving peak efficiencies within 70–80% of rated capacity. Diesel generation is also commonly sized to peak demand. These characteristics serve to constrain the possible RE penetration. While energy storage can relieve the constraint, this adds cost and complexity to the system. This paper identifies an alternative approach, redefining the low load capability of diesel generation. Low load diesel (LLD allows a diesel engine to operate across its full capacity in support of improved RE utilization. LLD uses existing diesel assets, resulting in a reduced-cost, low-complexity substitute. This paper presents an economic analysis of LLD, with results compared to conventional energy storage applications. The results identify a novel pathway for consumers to transition from low to medium levels of RE penetration, without additional cost or system complexity.

    To compare the cost, cost effectiveness, and sex equity of different intervention strategies within the English National Chlamydia Screening Programme. To develop a tool for calculating cost effectiveness of chlamydia control programmes at a local, national, or international level. An economic and mathematical modelling study with cost effectiveness analysis. Costs were restricted to those of screening and partner notification from the perspective of the NHS and excluded patient costs, the costs of reinfection, and costs of complications arising from initial infection. England. Population Individuals eligible for the National Chlamydia Screening Programme. Cost effectiveness of National Chlamydia Screening Programme in 2008-9 (as cost per individual tested, cost per positive diagnosis, total cost of screening, number screened, number infected, sex ratio of those tested and treated). Comparison of baseline programme with two different interventions-(i) increased coverage of primary screening in men and (ii) increased efficacy of partner notification. In 2008-9 screening was estimated to cost about £46.3m in total and £506 per infection treated. Provision for partner notification within the screening programme cost between £9 and £27 per index case, excluding treatment and testing. The model results suggest that increasing male screening coverage from 8% (baseline value) to 24% (to match female coverage) would cost an extra £22.9m and increase the cost per infection treated to £528. In contrast, increasing partner notification efficacy from 0.4 (baseline value) to 0.8 partners per index case would cost an extra £3.3m and would reduce the cost per infection diagnosed to £449. Increasing screening coverage to 24% in men would cost over six times as much as increasing partner notification to 0.8 but only treat twice as many additional infections. In the English National Chlamydia Screening Programme increasing the effectiveness of partner notification is likely

    Despite the growing use of assisted reproductive technologies (ART) worldwide, there is only a limited understanding of the economics of ART to inform policy about effective, safe and equitable financing of ART treatment. A review was undertaken of key studies regarding the costs and consequences of ART treatment, specifically examining the direct and indirect costs of treatment, economic drivers of utilization and clinical practice and broader economic consequences of ART-conceived children. The direct costs of ART treatment vary substantially between countries, with the USA standing out as the most expensive. The direct costs generally reflect the costliness of the underlying healthcare system. If unsubsidized, direct costs represent a significant economic burden to patients. The level of affordability of ART treatment is an important driver of utilization, treatment choices, embryo transfer practices and ultimately multiple birth rates. The costs associated with caring for multiple-birth ART infants and their mothers are substantial, reflecting the underlying morbidity associated with such pregnancies. Investment analysis of ART treatment and ART-conceived children indicates that appropriate funding of ART services appears to represent sound fiscal policy. The complex interaction between the cost of ART treatment and how treatments are subsidized in different healthcare settings and for different patient groups has far-reaching consequences for ART utilization, clinical practice and infant outcomes. A greater understanding of the economics of ART is needed to inform policy decisions and to ensure the best possible outcomes from ART treatment.

    The cost benefit of investments is devided into social and economic benefits. The postulates are discussed for the assessment of the cost benefit of capital costs of nuclear power plants. The relations are given for total cost benefit of capital costs expressed by the total profit rate of capital costs, and the absolute effectiveness exoressed by the socio-economic benefit of capital costs. The absolute cost benefit of capital costs is characterized by several complex indexes. Comparable capital cost benefit is used for assessing the effectiveness of interchangeable variants of solution. The minimum calculated costs serve as the criterion for selecting the optimal variant.

    This report comprises an initial economic and market appraisal of the proposals made by Materials Recycling Management (MRM) Ltd for a commercial plant engaged in waste treatment and energy recovery. The MRM design is an integrated waste handling system for commercial and industrial non hazardous wastes and civic amenity wastes. After primary separation into three selected broad waste categories, wastes are processed in the plant to recover basic recyclables such as paper, timber, plastics and metals. A quantity of material is directed for composting and the remainder converted into a fuel and combusted on site for energy recovery. Wastes unworthy of processing would be sent for disposal. A basic technical review has been undertaken. The focus of this review has been on the main processing plant where materials are segregated and the fuel and compost produced. (author)

    Full Text Available The establishment and application of economical levels demand a procedure to find with precision the insects population in a given moment. In the integrated management of plagues is not allowed the idea that any insect which is feeding from a part of plants requires a control action, that is why it is very important to determine the real effect that this insect population causes to the cultivation. Any decrease in the crop, constitutes a real waste of time; but when the economical level is defined, it is included an additional factor which is the measure cost of the plagues control. The determination of damages of levels is very important for economists, farming experts and specialists; while for producers is very significant its implementation with the objective to count with a sustainable and beneficial agriculture.

    The Idaho National Laboratory (INL) has teamed with University of Idaho and Boise State University to make the use of ADs more attractive by implementing a two-stage AD and coupling additional processes to the system. The addition of a polyhydroxyalkanoate (PHA) reactor, algae cultivation system, and a biomass treatment system such as fast-pyrolysis or hydrothermal liquefaction (HTL) would further sequester carbon and nutrients, as well as add valuable products that can be sold or used on-site to mitigate costs. The Decision-support for Digester-Algae IntegRation for Improved Environmental and Economic Sustainability (DAIRIEES) technoeconomic model will play a key role in evaluating the effectiveness and viability of this system to achieve economic and environmental sustainability by the dairy industry.

    2013-07-01

    Based on data from a 2005 survey conducted in Shanghai, China, this research examines the role of social capital in income inequality between rural migrants and urbanites. We find strong income return on social capital, in particular on social capital from strong ties. We also observe a great disparity in social capital possession between rural migrants and urban local residents. Although social capital from strong ties seems to be more important for rural migrants than for urbanites, local ties and high-status ties do not seem to benefit rural migrants. Hence, migrants not only suffer severe social capital deficits but also capital return deficits. Given the strong income returns on social capital and the substantial differences in access to and return on social capital between migrants and urban residents, social capital is consequently found to explain a large part of the income inequality between the two groups. Overall, our findings reveal macro-structural effects on the role of social capital in labor market stratification. In China, the lack of formal labor market mechanisms continues to create both a strong need for and opportunities for economic actions to be organized around informal channels via social relations. Yet, the long-standing institutional exclusion of migrants caused by the household registration system has resulted in pervasive social exclusion and discrimination which have substantially limited rural migrants' accumulation and mobilization of social capital. Under these conditions, social capital reinforces the economic inequality between migrants and urban residents in China. Such empirical evidence adds to our understanding of the role of social capital in the economic integration of migrants and in shaping intergroup inequality in general.

  1. Integrated approach to optimize operation and maintenance costs for operating nuclear power plants

    International Nuclear Information System (INIS)

    2006-06-01

    In the context of increasingly open electricity markets and the 'unbundling' of generating companies from former utility monopolies, an area of major concern is the economic performance of the existing fleet of nuclear power plants. Nuclear power, inevitably, must compete directly with other electricity generation sources. Coping with this competitive pressure is a challenge that the nuclear industry should meet if the nuclear option is to remain a viable one. This competitive environment has significant implications for nuclear plant operations, including, among others, the need for the more cost effective management of plant activities, and the greater use of analytical tools to balance the costs and benefits of proposed activities, in order to optimize operation and maintenance costs, and thus insure the economic competitiveness of existing nuclear power plants. In the framework of the activities on Nuclear Economic Performance Information System (NEPIS), the IAEA embarked in developing guidance on optimization of operation and maintenance costs for nuclear power plants. The report was prepared building on the fundamental that optimization of operation and maintenance costs of a nuclear power plant is a key component of a broader integrated business strategic planning process, having as overall result achievement of organization's business objectives. It provides advice on optimization of O and M costs in the framework of strategic business planning, with additional details on operational planning and controlling. This TECDOC was elaborated in 2004-2005 in the framework of the IAEA's programme on Nuclear Power Plant Operating Performance and Life Cycle Management, with the support of two consultants meetings and one technical meeting and based on contributions provided by participants. It can serve as a useful reference for the management and operation staff within utilities, nuclear power plant operators and regulators and other organizations involved in

    Economic appraisal can help guide policy-making for purchasing decisions, and treatment and management algorithms for health interventions. We conducted a systematic review of economic studies in cerebral palsy (CP) to inform future research. Economic studies published since 1970 were identified from seven databases. Two reviewers independently screened abstracts and extracted data following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Any discrepancies were resolved by discussion. Of 980 identified references, 115 were included for full-text assessment. Thirteen articles met standard criteria for a full economic evaluation, two as partial economic evaluations, and 18 as cost studies. Six were full economic evaluations alongside clinical studies or randomized controlled trials, whereas seven involved modelling simulations. The economic case for administration of magnesium sulfate for imminent preterm birth is compelling, achieving both health gain and cost savings. Current literature suggests intrathecal baclofen therapy and botulinum toxin injection are cost-effective, but stronger evidence for long-term effects is needed. Lifestyle and web-based interventions are inexpensive, but broader measurement of outcomes is required. Prevention of CP would avoid significant economic burden. Some treatments and interventions have been shown to be cost-effective, although stronger evidence of clinical effectiveness is needed. What this paper adds Cost-effectiveness evidence shows prevention is the most significant strategy. Some treatments are cost-effective, but stronger evidence for long-term effectiveness is required. Comparison of treatment costs is challenging owing to variations in methodologies and varying clinical indications. © 2018 Mac Keith Press.

    We sought to determine the economic costs associated with moderate and late preterm birth. An economic study was nested within a prospective cohort study. Infants born between 32(+0) and 36(+6)  weeks of gestation in the East Midlands of England. A sample of infants born at ≥37 weeks of gestation acted as controls. Data on resource use, estimated from a National Health Service (NHS) and personal social services perspective, and separately from a societal perspective, were collected between birth and 24 months corrected age (or death), and valued in pounds sterling, at 2010-11 prices. Descriptive statistics and multivariable analyses were used to estimate the relationship between gestational age at birth and economic costs. Cumulative resource use and economic costs over the first two years of life. Of all eligible births, 1146 (83%) preterm and 1258 (79%) term infants were recruited. Mean (standard error) total societal costs from birth to 24 months were £12 037 (£1114) and £5823 (£1232) for children born moderately preterm (32(+0) -33(+6)  weeks of gestation) and late preterm (34(+0) -36(+6)  weeks of gestation), respectively, compared with £2056 (£132) for children born at term. The mean societal cost difference between moderate and late preterm and term infants was £4657 (bootstrap 95% confidence interval, 95% CI £2513-6803; P economic costs over the first 2 years of life. Our economic estimates can be used to inform budgetary and service planning by clinical decision-makers, and economic evaluations of interventions aimed at preventing moderate and late preterm birth or alleviating its adverse consequences.

    2008-01-01

    To document the economic costs and benefits associated with providing dog guide services for blind individuals able to benefit from them. This study estimates the annual cost of dog guide services accounting for cost offsets associated with reduced informal and formal care costs over the working life of the animal (8 years). We estimated the cost per dog guide trained using previously unpublished survey data from dog guide training schools in the United States. We also estimated the incremental economic benefits as the reduction in costs associated with formal and informal care using published studies and a set of reasonable assumptions. Costs were discounted to 2006$ using a 3% discount rate. We found the average total cost per dog guide over its working life was $40,598, of which $21,568 were off-set by reductions in other costs. The costs associated with dog guides included $35,536 in dog acquisition costs and $5,061 for annual maintenance over the animal's working life. The economic benefits included $16,324 and $5,244 in reduced formal and informal care costs, respectively. The average net cost of dog guide ownership per year over the working life of the animal was $2,379. Using available information and reasonable assumptions, this study documents the costs of dog guides accounting for a limited number of cost off-setting elements. However, given limited available evidence, further study of the impact of guide dogs on the lives of blind individuals who use them should be conducted to validate this study's results.

    Injuries are one of the leading causes of death in the world. In Malaysia, injuries form one of the three main causes of mortality. They are also an important cause of permanent and temporary disability and work absenteeism in the productive age group. Increasing affluence and industrialization coupled with growing population and transportation needs in rapidly developing countries like Malaysia have resulted in a surge of road and occupational injuries. Three quarters of fatalities due to road, occupational, drowning and home injuries occur in those below 45 years of age. A majority of injuries in these categories are attributed to "human" factors and therefore can be prevented by public education and enforced training of workers. The total annual economic loss due to all types of injuries is estimated to be 2 billion Malaysian Ringgit (US$1 = MR2.76 approximately). The government is currently in the process of setting up full-time departments for road safety and occupational health and safety.

    Before the United States of America can arrive at a coherent national energy policy, several ongoing debates must be resolved - on environmental hazards, health impacts, and the direct economic consequences of alternative future energy options. No one strategy is obviously correct - or uniquely ethical. Each strategy has its drawbacks, each can be blocked by one or another coalition of interest groups. The public is poorly informed by the media. A single large coal-mine accident is far more extensively reported than a long series of isolated accidents at grade crossings for coal trains, and yet the latter causes more deaths each year. Similarly, the public debate on nuclear issues is focused on low-probability, high-consequence events. It is as though national policy were being framed by a gambler whose motto is 'it's only the stakes and not the odds that matter'. The two authors of this paper come from different disciplines, yet they both believe that the odds do matter. It is essential that the public be well informed about the health risks and the economic consequences of a moratorium on the civilian uses of nuclear energy in the USA. We think that such a moratorium would adversely affect health and the economy. These impacts although small in relation, say, to the overall death rate or to the overall gross national product are not small in an absolute sense The adverse consequences of a moratorium are much more certain, and surely outweigh the impacts of any plausible accident associated with the operation of power reactors.

It is as though national policy were being framed by a gambler whose motto is 'it's only the stakes and not the odds that matter'. The two authors of this paper come from different disciplines, yet they both believe that the odds do matter. It is essential that the public be well informed about the health risks and the economic consequences of a moratorium on the civilian uses of nuclear energy in the USA. We think that such a moratorium would adversely affect health and the economy. These impacts although small in relation, say, to the overall death rate or to the overall gross national product are not small in an absolute sense The adverse consequences of a moratorium are much more certain, and surely outweigh the impacts of any plausible accident associated with the operation of power reactors

    This paper presents a systems approach to evaluating the potential of integrated continuous bioprocessing for monoclonal antibody (mAb) manufacture across a product's lifecycle from preclinical to commercial manufacture. The economic, operational, and environmental feasibility of alternative continuous manufacturing strategies were evaluated holistically using a prototype UCL decisional tool that integrated process economics, discrete‐event simulation, environmental impact analysis, operational risk analysis, and multiattribute decision‐making. The case study focused on comparing whole bioprocesses that used either batch, continuous or a hybrid combination of batch and continuous technologies for cell culture, capture chromatography, and polishing chromatography steps. The cost of goods per gram (COG/g), E‐factor, and operational risk scores of each strategy were established across a matrix of scenarios with differing combinations of clinical development phase and company portfolio size. The tool outputs predict that the optimal strategy for early phase production and small/medium‐sized companies is the integrated continuous strategy (alternating tangential flow filtration (ATF) perfusion, continuous capture, continuous polishing). However, the top ranking strategy changes for commercial production and companies with large portfolios to the hybrid strategy with fed‐batch culture, continuous capture and batch polishing from a COG/g perspective. The multiattribute decision‐making analysis highlighted that if the operational feasibility was considered more important than the economic benefits, the hybrid strategy would be preferred for all company scales. Further considerations outside the scope of this work include the process development costs required to adopt continuous processing. © 2017 The Authors Biotechnology Progress published by Wiley Periodicals, Inc. on behalf of American Institute of Chemical Engineers Biotechnol.

    In the present work, the capture and storage of carbon dioxide from the fossil fuel power plant have been considered. The main objective was to analyze the thermodynamic performances and the technological aspects of two integrated gasification gas combined cycle plants (IGCC), as well as to give a forecast of the investment costs for the plants and the resulting energy consumptions. The first plant considered is an IGCC* plant (integrated gasification gas combined cycle plant with traditional shift reactors) characterized by the traditional water gas shift reactors and a CO 2 physical adsorption system followed by the power section. The second one is an IGCC M plant (integrated gasification gas combined cycle plant with membrane reactor) where the coal thermal input is the same as the first one, but the traditional shift reactors and the physical adsorption unit are replaced by catalytic palladium membrane reactors (CMR). In the present work, a mono-dimensional computational model of the membrane reactor was proposed to simulate and evaluate the capability of the IGCC M plant to capture carbon dioxide. The energetic performances, efficiency and net power of the IGCC* and IGCC M plants were, thus, compared, assuming as standard a traditional IGCC plant without carbon dioxide capture. The economical aspects of the three plants were compared through an economical analysis. Since the IGCC* and IGCC M plants have additional costs related to the capture and disposal of the carbon dioxide, a Carbon Tax (adopted in some countries like Sweden) proportional to the number of kilograms of carbon dioxide released in the environment was assumed. According to the economical analysis, the IGCC M plant proved to be more convenient than the IGCC* one

    Initiated in 2008, the SEGIS initiative is a partnership involving the U.S. DOE, Sandia National Laboratories, private sector companies, electric utilities, and universities. Projects supported under the initiative have focused on the complete-system development of solar technologies, with the dual goal of expanding renewable PV applications and addressing new challenges of connecting large-scale solar installations in higher penetrations to the electric grid. Petra Solar, Inc., a New Jersey-based company, received SEGIS funds to develop solutions to two of these key challenges: integrating increasing quantities of solar resources into the grid without compromising (and likely improving) power quality and reliability, and moving the design from a concept of intelligent system controls to successful commercialization. The resulting state-of-the art technology now includes a distributed photovoltaic (PV) architecture comprising AC modules that not only feed directly into the electrical grid at distribution levels but are equipped with new functions that improve voltage stability and thus enhance overall grid stability. This integrated PV system technology, known as SunWave, has applications for 'Power on a Pole,' and comes with a suite of technical capabilities, including advanced inverter and system controls, micro-inverters (capable of operating at both the 120V and 240V levels), communication system, network management system, and semiconductor integration. Collectively, these components are poised to reduce total system cost, increase the system's overall value and help mitigate the challenges of solar intermittency. Designed to be strategically located near point of load, the new SunWave technology is suitable for integration directly into the electrical grid but is also suitable for emerging microgrid applications. SunWave was showcased as part of a SEGIS Demonstration Conference at Pepco Holdings, Inc., on September 29, 2011, and is presently

    Highlights: • Develop a thermo-economic analysis of an integrated solar-power generation system. • A thermodynamic optimization is proposed to maximize system performance. • Select the optimum nanofluid to replace conventional heating fluids inside a PTSC. • Study the effect of thermal energy storage on performance and cost of the system. • Perform monthly and daily analyses to analyze system behavior using nanofluids. - Abstract: In this paper, a thermo-economic analysis of an Integrated Solar Regenerative Rankine Cycle (ISRRC) is performed. The ISRRC consists of a nanofluid-based Parabolic Trough Solar Collector (PTSC), and a Thermal Energy Storage System (TES) integrated with a Regenerative Rankine Cycle. The effect of dispersing metallic and non-metallic nanoparticles into conventional heating fluids on the output performance and cost of the ISRRC is studied for different volume fractions and for three modes of operation. The first mode assumes no storage, while the second and the third assume a storage system with a storage period of 7.5 h and 10 h respectively. For the modes of operation with the TES, the charging and discharging cycles are explained. The results show that the presence of the nanoparticles leads to an increase in the overall energy produced by the ISRRC for all modes of operation, causing a decrease in the Levelized Cost of Electricity (LEC), and an increase in the net savings of the ISRRC. After comparing the three modes of operation, it is established that the existence of a storage system leads to a higher power generation, and a lower LEC; however, the efficiency of the cycle drops. It is seen that the maximum increase in the annual energy output of the ISRRC caused by the addition of Cu nanoparticles to Syltherm 800 is approximately 3.1%, while the maximum increase in the net savings is about 2.4%.

    This paper examines the cost of meeting the Kyoto Protocol commitments under alternative assumptions regarding technology and technical change. Real GDP is modeled as a function of the capital, labor, and energy inputs. The analysis is based on data for 23 Annex 1 countries from 1965 to 1999. Two important results emerge. First, the standard assumption of Hicks neutral technical change and time and scale independent output elasticities is not supported by the data. Second, when technical change is allowed to be biased in favor of the energy and capital inputs, and when the output elasticities vary with the level of factor use and over time, the loss in real GDP due to the Kyoto commitments rises substantially. On average, the loss in real GDP is one and a half times higher than obtained under the standard assumptions. 26 refs

    Under the German Atomic Energy Act, the federal government is responsible for the construction of repositories for radioactive waste. Steps to this end were initiated early on when the first nuclear power plants were commissioned in the 1960s. They resulted, among other approaches, in the decisions and site selection procedures for the Gorleben salt dome and the former Konrad iron ore mine as potential repository sites in the 1970s and 1980s. In 2000, the federal government imposed a moratorium of three up to a maximum of ten years on further exploration activities at Gorleben in order to dispel doubts held by the German Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU). A positive plans approval decision on Konrad was publicized in May 2002. Emplacement could begin roughly in 2010-2012, once legal certainty will have been ensured. In February 1999, BMU appointed a working party to establish site selection procedures for repositories (AkEnd) which was to develop a transparent procedure of finding and selecting sites for the final storage of all kinds of radioactive waste in Germany. The procedure finally proposed by AkEnd implies considerable uncertainty, inter alia, about its legal implementability, the time required, and funding. For the Gorleben salt dome, for instance, additional exploration and procedures alone could give rise to extra costs of euro 3-5 billion, compared to merely continuing project activities. Similar extra costs are likely to arise especially to the government if emplacement in Konrad were to be delayed. Under aspects of technical safety, the speediest possible emplacement of all types of waste in deep geologic formations is preferable to all other options. Hence, further exploration of Gorleben should be completed quickly, and the Konrad project should be implemented, after due consideration of all factors. (orig.) [de

    An integrated engineering and cost model has been developed as a part of an overall research project for exploring the technical, environmental and economic feasibility of disposing coal combustion byproducts and flue gas desulfurisation products in underground coal mines in Illinois. The features of the model have been keyed in user-friendly software. In this paper, the purpose and the structure of the model are described. The capabilities of the software are illustrated through an example involving transportation of byproducts in containers from a power plant to a mine site, and subsequent placement of the byproducts in a abandoned underground coal mine using a hydraulic injection system. 3 refs.

    Thermal efficiency, capacity factor, environmental considerations, investment cost, fuel and O and M costs are the main parameters for technical and economic assessment of solar power plants. This analysis has shown that the Integrated Solar Combined Cycle System with 67 MW e solar field(ISCCS-67) is the most suitable plan for the first solar power plant in Iran. The Levelized Energy Costs of combined cycle and ISCCS-67 power plants would be equal if 49 million dollars of ISCCS-67 capital cost supplied by the international environmental organizations such as Global Environmental Facilities and World Bank. This study shows that an ISCCS-67 saves 59 million dollars in fuel consumption and reduces about 2.4 million ton in CO 2 emission during 30 years operating period. Increasing of steam turbine capacity by 50%, and 4% improvement in overall efficiency are other advantages of iSCCS-67 power plant. The LEC of ISCCS-67 is 10% and so 33% lower than the combined cycle and gas turbine, respectively, at the same capacity factor with consideration of environmental costs

    The primacy of a nuclear fusion reactor in a competitive energy market remarkably depends on to what extent the reactor contributes to reduce the externalities of energy. The reduction effects are classified into two effects, which have quite dissimilar characteristics. One is an effect of environmental dimensions. The other is related to energy security. In this study I took up the results of EC's ExternE project studies as a representative example of the former effect. Concerning the latter effect, I clarified the fundamental characteristics of externalities related to energy security and the conceptual framework for the purpose of evaluation. In the socio-economical evaluation of research into and development investments in nuclear fusions reactors, the public will require the development of integrated evaluation systems to support the cost-effect analysis of how well the reduction effects of externalities have been integrated with the effects of technological innovation, learning, spillover, etc. (author)

    Complete text of publication follows: In the context of growing scientific evidence about a relationship between ongoing climate change and man-made Greenhouse Gases (GHGs) emissions, policy makers will meet in Copenhagen at the end of 2009 in order to negotiate a new agreement to reduce GHGs emissions. The previous agreement - the Kyoto Protocol that was signed in 1997 and will end in 2012 - encompassed relatively modest emission reductions undertaken by a group of countries (Annex 1 countries). Such a partial action gave rise to concerns about the effectiveness of such a scheme - potentially undermined by the existence of carbon leakages - and its adverse effect on the international competitiveness of the energy-intensive industries in the Annex 1 countries. More importantly, it is now clear that industrialized countries alone are unable to stabilize the earth climate, an objective that is out of range without the active participation of the emerging economies. Therefore, the scenarios that will be discussed at the Copenhagen meeting will need to be much more ambitious, with emissions objectives that will imply a major restructuring of the world economy, putting it on the way of growth without carbon. This presentation will address the trade-offs between economic growth and environmental risks in the choice of a post-Kyoto strategy

    Abstract The Centers for Disease Control and Prevention (CDC) in the United States has declared insufficient sleep a “public health problem.” Indeed, according to a recent CDC study, more than a third of American adults are not getting enough sleep on a regular basis. However, insufficient sleep is not exclusively a US problem, and equally concerns other industrialised countries such as the United Kingdom, Japan, Germany, or Canada. According to some evidence, the proportion of people sleeping less than the recommended hours of sleep is rising and associated with lifestyle factors related to a modern 24/7 society, such as psychosocial stress, alcohol consumption, smoking, lack of physical activity and excessive electronic media use, among others. This is alarming as insufficient sleep has been found to be associated with a range of negative health and social outcomes, including success at school and in the labour market. Over the last few decades, for example, there has been growing evidence suggesting a strong association between short sleep duration and elevated mortality risks. Given the potential adverse effects of insufficient sleep on health, well-being and productivity, the consequences of sleep-deprivation have far-reaching economic consequences. Hence, in order to raise awareness of the scale of insufficient sleep as a public-health issue, comparative quantitative figures need to be provided for policy- and decision-makers, as well as recommendations and potential solutions that can help tackling the problem.

    The costs of power generation are an important point in the electricity industry. The present report tries to supply a model representation for these problems. The costs of power generation for base load, average and peak load power stations are examined on the basis of fossil energy sources, nuclear power and water power. The methods of calculation where dynamic investment calculation processes are used, are given in the shape of formulae. From the point of view of long term prediction, power generation cost sensitivity studies are added to the technical, economic and energy-political uncertainties. The sensitivity of models for calculations is examined by deterministic and stochastic processes. In the base load and average region, power generation based on nuclear power and water power is economically more favourable than that from fossilfired power stations. Even including subsidies, this cost advantage is not in doubt. In the peak load region, pumped storage power stations are more economic than fossilfired power stations. (orig.) [de

    Social justice is the moral imperative to avoid and remediate unfair distributions of societal disadvantage. In priority setting in healthcare and public health, social justice reaches beyond fairness in the distribution of health outcomes and economic impacts to encompass fairness in the distribution of policy impacts upon other dimensions of well-being. There is an emerging awareness of the need for economic evaluation to integrate all such concerns. We performed a systematic review (1) to describe methodological solutions suitable for integrating social justice concerns into economic evaluation, and (2) to describe the challenges that those solutions face. To be included, publications must have captured fairness considerations that (a) involve cross-dimensional subjective personal life experience and (b) can be manifested at the level of subpopulations. We identified relevant publications using an electronic search in EMBASE, PubMed, EconLit, PsycInfo, Philosopher's Index, and Scopus, including publications available in English in the past 20 years. Two reviewers independently appraised candidate publications, extracted data, and synthesized findings in narrative form. Out of 2388 publications reviewed, 26 were included. Solutions sought either to incorporate relevant fairness considerations directly into economic evaluation or to report them alongside cost-effectiveness measures. The majority of reviewed solutions, if adapted to integrate social justice concerns, would require their explicit quantification. Four broad challenges related to the implementation of these solutions were identified: clarifying the normative basis; measuring and determining the relative importance of criteria representing that basis; combining the criteria; and evaluating trade-offs. All included solutions must grapple with an inherent tension: they must either face the normative and operational challenges of quantifying social justice concerns or accede to offering incomplete policy

    Full Text Available Abstract Background The aim of the ACE-Obesity study was to determine the economic credentials of interventions which aim to prevent unhealthy weight gain in children and adolescents. We have reported elsewhere on the modelled effectiveness of 13 obesity prevention interventions in children. In this paper, we report on the cost results and associated methods together with the innovative approach to priority setting that underpins the ACE-Obesity study. Methods The Assessing Cost Effectiveness (ACE approach combines technical rigour with 'due process' to facilitate evidence-based policy analysis. Technical rigour was achieved through use of standardised evaluation methods, a research team that assembles best available evidence and extensive uncertainty analysis. Cost estimates were based on pathway analysis, with resource usage estimated for the interventions and their 'current practice' comparator, as well as associated cost offsets. Due process was achieved through involvement of stakeholders, consensus decisions informed by briefing papers and 2nd stage filter analysis that captures broader factors that influence policy judgements in addition to cost-effectiveness results. The 2nd stage filters agreed by stakeholders were 'equity', 'strength of the evidence', 'feasibility of implementation', 'acceptability to stakeholders', 'sustainability' and 'potential for side-effects'. Results The intervention costs varied considerably, both in absolute terms (from cost saving [6 interventions] to in excess of AUD50m per annum and when expressed as a 'cost per child' estimate (from Conclusion The use of consistent methods enables valid comparison of potential intervention costs and cost-offsets for each of the interventions. ACE-Obesity informs policy-makers about cost-effectiveness, health impact, affordability and 2nd stage filters for important options for preventing unhealthy weight gain in children.

    Relatively little is known about patterns of injury at the community level in Vietnam and their economic consequences. This study sought to estimate the costs of various unintentional injuries in Bavi District during one year; to describe how costs depended on gender, age, circumstances, and severity of injury; and to describe how the economic burden of unintentional injuries was distributed between households, government, and health insurance agency. A cohort study was undertaken, which involved four cross-sectional household surveys among sampled communities in the Bavi District during the year 2000, each asking about injuries in the preceding three months. The costing system in public healthcare in Vietnam was applied as well as information from the victims. The total cost of injuries over one year in Bavi District was estimated to be D3,412,539,000 (Vietnamese dong) (US$235,347), equivalent to the annual income of 1,800 people. In total, 90% of this economic burden fell on households, only 8% on government, and 2% on the health insurance agency. The cost of a severe injury to the corresponded to approximately seven months of earned income. Home and traffic injuries together accounted for more than 80% of the total cost, 45% and 38% respectively. The highest unit cost was related to traffic injuries, followed by home, "other", work-related, and school injuries in descending order. The results can be considered as an economic baseline that can be used in evaluations of future interventions aimed at preventing injuries.

    This effort improves the quantitative information available for use in evaluating actions that alter health risks due to population exposure to ionizing radiation. To project the potential future costs of changes in health effects risks, Pacific Northwest Laboratory (PNL) constructed a probabilistic computer model, Health Effects Costs Model (HECOM), which utilizes the health effect incidence estimates from accident consequences models to calculate the discounted sum of the economic costs associated with population exposure to ionizing radiation. Application of HECOM to value-impact and environmental impact analyses should greatly increase the quality of the information available for regulatory decision making. Three major types of health effects present risks for any population sustaining a significant radiation exposure: acute radiation injuries (and fatalities), latent cancers, and impairments due to genetic effects. The literature pertaining to both incidence and treatment of these health effects was reviewed by PNL and provided the basis for developing economic cost estimates. The economic costs of health effects estimated by HECOM represent both the value of resources consumed in diagnosing, treating, and caring for the patient and the value of goods not produced because of illness or premature death due to the health effect. Additional costs to society, such as pain and suffering, are not included in the PNL economic cost measures since they do not divert resources from other uses, are difficult to quantify, and do not have a value observable in the marketplace. 83 refs., 3 figs., 19 tabs

    Simulation models are used widely in pharmacology, epidemiology and health economics (HEs). However, there have been no attempts to incorporate models from these disciplines into a single integrated model. Accordingly, we explored this linkage to evaluate the epidemiological and economic impact of oseltamivir dose optimisation in supporting pandemic influenza planning in the USA. An HE decision analytic model was linked to a pharmacokinetic/pharmacodynamics (PK/PD) - dynamic transmission model simulating the impact of pandemic influenza with low virulence and low transmissibility and, high virulence and high transmissibility. The cost-utility analysis was from the payer and societal perspectives, comparing oseltamivir 75 and 150 mg twice daily (BID) to no treatment over a 1-year time horizon. Model parameters were derived from published studies. Outcomes were measured as cost per quality-adjusted life year (QALY) gained. Sensitivity analyses were performed to examine the integrated model's robustness. Under both pandemic scenarios, compared to no treatment, the use of oseltamivir 75 or 150 mg BID led to a significant reduction of influenza episodes and influenza-related deaths, translating to substantial savings of QALYs. Overall drug costs were offset by the reduction of both direct and indirect costs, making these two interventions cost-saving from both perspectives. The results were sensitive to the proportion of inpatient presentation at the emergency visit and patients' quality of life. Integrating PK/PD-EPI/HE models is achievable. Whilst further refinement of this novel linkage model to more closely mimic the reality is needed, the current study has generated useful insights to support influenza pandemic planning.

    Malignant blood disorders are a leading contributor to cancer incidence and mortality across Europe. Despite their burden, no study has assessed the economic effect of blood cancers in Europe. We aimed to assess the economic burden of malignant blood disorders across the 28 countries in the European Union (EU), Iceland, Norway, and Switzerland. Malignant blood disorder-related costs were estimated for 28 EU countries, Iceland, Norway, and Switzerland for 2012. Country-specific costs were estimated with aggregate data on morbidity, mortality, and health-care resource use obtained from international and national sources. Health-care costs were estimated from expenditure on primary, outpatient, emergency, inpatient care, and drugs. Costs of informal care and productivity losses due to morbidity and early death were also included. For countries in the EU, malignant blood disorders were compared with the economic burden of overall cancer. Malignant blood disorders cost the 31 European countries €12 billion in 2012. Health-care cost €7·3 billion (62% of total costs), productivity losses cost €3·6 billion (30%), and informal care cost €1 billion (8%). For the EU countries, malignant blood disorders cost €6·8 billion (12%) of the total health-care expenditure on cancer (€57 billion), with this proportion being second only to breast cancer. In terms of total cancer costs in the EU (€143 billion), malignant blood disorders cost €12 billion (8%). Malignant blood disorders represent a leading cause of death, health-care service use, and costs, not only to European health-care systems, but to society overall. Our results add to essential public health knowledge needed for effective national cancer-control planning and priorities for public research funding. European Hematology Association.

  12. Towards a Single Market: A 21st Century Vision for Asia Pacific Economic Integration

    Full Text Available APEC leaders can take pride in progress towards free and open trade. There will always be more to do to integrate Asia Pacific economies. 2010 is the time to look beyond border barriers to trade and adopt a new post-Bogor vision of a single market. Traditional border barriers to trade in some sensitive products remain costly, but affect only a rapidly shrinking part of international commerce. Today, it is more efficient to concentrate on problems of communications and logistics, combined with the lack of efficiency, transparency and sometimes arbitrary implementation of economic policies in different economies. The effective constraint on collective action to deal with these problems is not political will. It is limited capacity to design and implement the necessary policy reform. Creating the necessary capacity needs a unifying vision to deal all obstacles to genuine economic integration, that is, to build a single market. In doing so, Asia Pacific governments can learn from the European Union experience. But they need to promote ever-deeper economic integration without relying on a supra-national authority. Like free and open trade, a single market is a vision which can only be approached, rather than reached by any deadline-it is a point of reference for the many things that need to be done to integrate Asia Pacific economies in a meaningful way. Asia Pacific governments should be encouraged to set their own medium-term targets for progress towards well-defined ingredients of a single market. Strict selection criteria should be used to identify options for cooperation which build on what APEC is already doing and which are in line with the priorities of most member economies. An ambitious program to enhance the efficiency of supply chains could set a successful example and generate the confidence to do more.

    Highlights: • The integration of a small-scale commercial ORC in a real case study was analyzed. • The possibility of recovering the waste heat produced by an ICE was considered. • A semi-empirical steady-state model of the commercial small scale ORC was created. • Both direct and indirect costs was considered in the business model. • The ORC integration was not economically feasible due to increased indirect costs. - Abstract: The ORC certainly represents a promising solution for recovering low-grade waste heat in industries. However, the efficiency of commercial small-scale ORC solutions is still too low in comparison with the high initial costs of the machine and the lack of simulation models specifically developed for commercial ORC systems prevents industries from defining an accurate business model to correctly evaluate the ORC integration in real industrial processes. This paper presents a techno-economic feasibility analysis of the integration of a small-scale commercial ORC in a real case study, represented by a highly-efficient industrial distillery. The integration is aimed at maximizing the electricity auto-production by exploiting the heat produced by an internal combustion engine, already partially recovered in internal thermal processes. To analyze the influence of the ORC integration on the industrial processes, a semi-empirical steady-state model of the commercial small scale ORC was created. The model made it possible to simulate the performance of the commercial ORC within a hypothetical scenario involving the use of the heat from the cooling water and from the exhaust gases of the internal combustion engine. A detailed thermo-dynamic analysis has been carried out to study the effects of the ORC integration on the plant’s energy system with particular focus on the two processes directly affected by ORC integration, namely vapor production and the drying process of the grape marc. The analysis highlighted the great importance in the

    This paper presents a new methodology for energy integration of systems that require absorption refrigeration. It allows heat exchange among process hot and cold streams and the integration of excess process heat as well as external utilities provided by solar energy, fossil fuels and biofuels. An optimization formulation is developed to address the multiple objectives of simultaneously minimizing the total annualized cost and the greenhouse gas emissions while the social impact is measured by the number of jobs generated by the project in the entire life cycle. The economic function accounts for the tax credit obtained by the reduction of greenhouse gas emissions when cleaner technologies are used. The proposed model also considers the optimal selection of different types of solar collectors and the optimal time-based usage of solar energy, fossil fuel, and biofuel. Two example problems are presented to show the applicability of the proposed methodology. -- Highlights: ► An approach for the thermal integration of refrigeration processes is proposed. ► Different forms of sustainable energies are considered in the optimization process. ► Economic and environmental objectives are considered quantifying the number of jobs. ► The availability for the different forms of energy is taken into account. ► Results show significant advantages obtained with the proposed approach

    Full Text Available Fast developing technology, increased production and the search for market has paved the way for globalization after the industrial revolution. Transnational borders has almost disappeared today’s World which faced with two great wars and a lot more threat during the 20th century. Economic integrations gained speed after the two Great World Wars. Countries started to come together because of advancing technology, transportation facilities, security concerns and increased competition during this period. Thus, political, military and cultural integration movements established and also economic integration movements gained speed. Economic, political, military integrations like EU, APEC, ASEAN, NAFTA, WTO and NATO have showed impact in every region of the World. There are a lot of regional and global integration movements in the World. Globalization leads to act the World as if it had a single center increasingly. This case is important in terms of economic integration of the national economies. The main objective of economic integration is an effort to eliminate all barriers to trade. In this work, the structure of the economic integration process and its effect on the World economy will be examined. APEC, ASEAN and EU can be considered as one of the best samples of the economic integration in the World. General structures, macroeconomic performances and their effects on integration process of these three economic integrations will be discussed. As a result, APEC stands out with its developing large trade volume, ASEAN is noted with its great speed of economic development and, European Union differs with its large gross domestic product per capita. APEC, EU and ASEAN organizations show that both developed and developing countries can not remain outside of integration. Each of the three integration movement has been making great contributions to the World to integrate. World is almost becoming a single country thanks to the economic integration.

    2011-01-01

    Few studies have examined the economic cost of psychoses other than schizophrenia and there have been no studies of the economic cost of pathways to care in patients with their first episode of psychosis. The aims of this study were to explore the economic cost of pathways to care in patients with a first episode of psychosis and to examine variation in costs. Data on pathways to care for first episode psychosis patients referred to specialist mental health services in south-east London and Nottingham between 1997-2000. Costs of pathway events were estimated and compared between diagnostic groups. The average costs for patients in south-east London were £54 (CI £33-£75) higher, compared to patients in Nottingham. Across both centres unemployed patients had £25 (CI £7-£43) higher average costs compared to employed patients. Higher costs were associated with being unemployed and living in south-east London and these differences could not be accounted for by any single factor. This should be considered when the National Health Service (NHS) is making decisions about funding.

  18. Too costly to matter: Economics of nuclear power for Saudi Arabia

    International Nuclear Information System (INIS)

    Ahmad, Ali; Ramana, M.V.

    2014-01-01

    Saudi Arabia has ambitious plans for nuclear power. Given this context, this paper examines the economics of nuclear power and compares it to two other sources of electricity, natural gas and solar energy. It calculates the costs of electricity generation, water desalination and the opportunity cost associated with forgone oil and gas revenues. A sensitivity analysis is included to account for variations in important parameters within the comparative cost analysis. Our results suggest that for a large range of parameters, the economics of nuclear power are not favorable in comparison with natural gas, even if the currently low domestic natural gas prices in Saudi Arabia were to rise substantially. Further, electricity from solar plants has the potential to be cheaper than nuclear power within the next decade if the rapid decline in solar energy costs in the last decade continue, i.e., before the first planned nuclear power plant would be completed. However, unless the price of oil drops substantially below current values, it would be more economically optimal to export the oil than using it for generating electricity. - Highlights: • Future projections show nuclear power is not cost effective for Saudi Arabia. • A combination of solar and natural gas could largely meet future electricity demand. • There are multiple, non-economic, motivations for Saudi Arabia's nuclear program. • Saudi Arabia would economically benefit by not using oil for electricity generation

    Star celebrities such as Rock Hudson, Freddie Mercury, Magic Johnson, and Isaac Asimov have unfortunately something in common: they were all victims of the HIV global pandemic. Since then HIV infection has become considered a pandemic disease, and it is regarded as a priority in healthcare worldwide. It is ranked as the first cause of death among young people in industrialized countries, and it is recognized as a public healthcare problem due to its human, social, mass media, and economic impact. Incorporation of new and highly active antiretroviral treatment, available since 1996 for HIV/AIDS treatment, has provoked a radical change in the disease pattern, as well as in the impact on patient survival and quality of life. The pharmaceutical industry's contribution, based on the research for more active new drugs, has been pivotal. Mortality rates have decreased significantly in 20 years by 50% and now AIDS is considered a chronic and controlled disease. In this review we have studied the impact of HAART treatment on infected patients, allowing them to maintain their status as active workers and the decreased absenteeism from work derived from this, contributing ultimately to overall social wealth and, thus, to economic growth. Furthermore, an analysis of the impact on healthcare costs, quality of life per year, life per year gained, cost economic savings and cost opportunity among other parameters has shown that society and governments are gaining major benefits from the inclusion of antiretroviral therapies in HIV/AIDS patients.

    M. Elena Nenni

    2013-01-01

    Full Text Available An Integrated Logistic Support (ILS service has the objective of improving a system’s efficiency and availability for the life cycle. The system constructor offers the service to the customer, and she becomes the Contractor Logistic Support (CLS. The aim of this paper is to propose an approach to support the CLS in the budget formulation. Specific goals of the model are the provision of the annual cost of ILS activities through a specific cost model and a comprehensive examination of expected benefits, costs and savings under alternative ILS strategies. A simple example derived from an industrial application is also provided to illustrate the idea. Scientific literature is lacking in the topic and documents from the military are just dealing with the issue of performance measurement. Moreover, they are obviously focused on the customer’s perspective. Other scientific papers are general and focused only on maintenance or life cycle management. The model developed in this paper approaches the problem from the perspective of the CLS, and it is specifically tailored on the main issues of an ILS service.

    Full Text Available Different forms of cooperation and regional integration, implying specific institutional agreements and instruments, have been developed in the last decades in the EU neighbourhood. The offer provided by the Eastern Partnership (EaP, which includes both economic and political objectives, has not proven attractive enough for the Eastern Neighbourhood. The region is currently divided between two global powers (EU and Russia and two competing regional integration areas, the Deep and Comprehensive Free Trade Area and the Eurasian Single Economic Space. The paper focuses on the main limits of the economic tools included in the EU’s current offer and proposes several directions for EaP’s reform.

    Based on available epidemiologic, health economic, and international population statistics literature, the cost of epilepsy in Europe was estimated. Europe was defined as the 25 European Union member countries, Iceland, Norway, and Switzerland. Guidelines for epidemiological studies on epilepsy were used for a case definition. A bottom-up prevalence-based cost-of-illness approach, the societal perspective for including the cost items, and the human capital approach as valuation principle for indirect costs were used. The cost estimates were based on selected studies with common methodology and valuation principles. The estimated prevalence of epilepsy in Europe in 2004 was 4.3-7.8 per 1,000. The estimated total cost of the disease in Europe was euro15.5 billion in 2004, indirect cost being the single most dominant cost category (euro8.6 billion). Direct health care costs were euro2.8 billion, outpatient care comprising the largest part (euro1.3 billion). Direct nonmedical cost was euro4.2 billion. That of antiepileptic drugs was euro400 million. The total cost per case was euro2,000-11,500 and the estimated cost per European inhabitant was euro33. Epilepsy is a relevant socioeconomic burden at individual, family, health services, and societal level in Europe. The greater proportion of such burden is outside the formal health care sector, antiepileptic drugs representing a smaller proportion. Lack of economic data from several European countries and other methodological limitations make this report an initial estimate of the cost of epilepsy in Europe. Prospective incidence cost-of-illness studies from well-defined populations and common methodology are encouraged.

    Highlights: • Seven configurations were studied regarding the integration of solar thermal energy. • Economic analysis was conducted on new built plants and retrofitted power plants. • Using solar thermal energy to preheat high pressure feedwater shows the best performance. - Abstract: In order to mitigate CO_2 emission and improve the efficiency of the utilization of solar thermal energy (STE), solar thermal energy is proposed to be integrated into a power plant. In this paper, seven configurations were studied regarding the integration of STE. A 300 MWe subcritical coal-fired plant was selected as the reference, chemical absorption using monoethanolamine solvent was employed for CO_2 ​capture, and parabolic trough collectors and evacuated tube collectors were used for STE collection. Both technical analysis and economic evaluation were conducted. Results show that integrating solar energy with post-combustion CO_2​ capture can effectively increase power generation and reduce the electrical efficiency penalty caused by CO_2 capture. Among the different configurations, Config-2 and Config-6, which use medium temperature STE to replace high pressure feedwater without and with CO_2 capture, show the highest net incremental solar efficiency. When building new plants, integrating solar energy can effectively reduce the levelized cost of electricity (LCOE). The lowest LCOE, 99.28 USD/MWh, results from Config-6, with a parabolic trough collector price of 185 USD/m"2. When retrofitting existing power plants, Config-6 also shows the highest net present value (NPV), while Config-2 has the shortest payback time at a carbon tax of 50 USD/ton CO_2. In addition, both LCOE and NPV/payback time are clearly affected by the relative solar load fraction, the price of solar thermal collectors and the carbon tax. Comparatively, the carbon tax can affect the configurations with CO_2 capture more clearly than those without CO_2 capture.

    2008-04-01

    Researchers have been at the forefront of applying new costing methods to drug abuse treatment programs and innovations. The motivation for such work has been to improve costing accuracy. Recent work has seen applications initiated in establishing charts of account and cost accounting for service delivery. As a result, researchers now have available five methods to apply to the costing of drug abuse treatment programs. In all areas of costing, there is room for more research on costing concepts and measurement applications. Additional work would be useful in establishing studies with activity-based costing for both research and managerial purposes. Studies of economies of scope are particularly relevant because of the integration of social services and criminal justice in drug abuse treatment. In the long run, managerial initiatives to improve the administration and quality of drug abuse treatment will benefit directly from research with new information on costing techniques.

    Two different options for the autonomous power supply of rural or/and remote buildings are examined in this study. The first one involves a PV - diesel based power system, while the second one integrates RES and hydrogen technologies for the development of a self - sustained power system. The main objective is the replacement of the diesel generator and a comparison between these two options for autonomous power supply. Model simulations of the two power systems before and after the replacement, an optimization of the component sizes and a techno - economic analysis have been performed for the purpose of this study. A sensitivity analysis taking into account future cost scenarios for hydrogen technologies is also presented. The results clearly show that the Cost of Energy Produced (COE) from the PV - hydrogen technologies power system is extremely higher than the PV - diesel power system. However, the adopted PV - hydrogen technologies power system reduces to zero the Green - House Gas (GHG) emissions. Moreover, the sensitivity analysis indicates that COE for the latter system can be further reduced by approximately 50% compared to its initial value. This could be achieved by reducing critical COE's parameters, such as PEM electrolyser and fuel cell capital costs. Hence, a possible reduction on the capital costs of hydrogen energy equipment in combination with emissions reduction mentioned above could make hydrogen - based power systems more competitive.

    This study aims to demonstrate the importance of the opportunity cost in using da Vinci robotic surgery, assisted by a comprehensive review of the literature to determine the differences in the total cost of surgery and operative time in traditional laparoscopic surgery and da Vinci robotic surgery. We identified the studies comparing the use of traditional laparoscopic surgery with robotics during the period 2002-2012 in the electronic economic evaluation databases, and another electronic search was performed for publications by Spanish hospitals in the same period to calculate the opportunity cost. A meta-analysis of response variables considering the total cost of the intervention and surgical time was completed using the items selected in the first revision, and their differences were analyzed. We then calculated the opportunity cost represented by these time differences using the data obtained from the studies in the second review of the literature. Nine items were selected in the first review and three in the second. Traditional laparoscopic surgery has a lower cost than the da Vinci (p < 0.00001). Robotic surgery takes longer (8.0-65.5 min) than traditional surgery (p < 0.00001), and this difference represents an average opportunity cost for robot use of € 489.98, with a unit cost factor/time which varies according to the pathology dealt with, from € 8.2 to 18.7/min. The opportunity cost is a quantity that must be included in the total cost of using a surgical technology within an economic cost analysis in the context of an economic evaluation.

    Asthma is the first cause of children hospitalization and need for emergency and impose high economic burden on the families and governments. We aimed to investigate the economic burden of pediatric asthma and its contribution to family health budget in Iran. Overall, 283 pediatric asthmatic patients, who referred to two tertiary pediatric referral centers in Tehran capital of Iran, included from 2010-2012. Direct and indirect asthma-related costs were recorded during one-year period. Data were statistically analyzed for finding association between the costs and factors that affect this cost (demographic variables, tobacco smoke exposure, control status of asthma and asthma concomitant diseases). Ninety-two (32.5%) females and 191(67.5%) males with the age range of 1-16 yr old were included. We found the annual total pediatrics asthma related costs were 367.97±23.06 USD. The highest cost belonged to the medications (69%) and the lowest one to the emergency (2%). We noticed a significant increasing in boys' total costs ( P =0.011), and 7-11 yr old age group ( P =0.018). In addition, we found significant association between total asthma costs and asthma control status ( P =0.011). The presence of an asthmatic child can consume nearly half of the health budget of a family. Our results emphasis on improving asthma management programs, which leads to successful control status of the disease and reduction in economic burden of pediatric asthma.

    The aim was to assess the impact on economic costs and length of stay (LOS) of postoperative complications. 5,822 records from BMDS (2014-2015) are included. A descriptive, univariate and multivariate study evaluated the correlation between complications, Clavien-Dindo grade and vacation periods with LOS and economic costs, based on a full-cost model, aggregated by DRG. Mean cost per stay was €676.71, and €4,309.02 per episode. Complications appeared in 639 patients (11%). Admission to ICU was required in 203 patients, re-operation in 134 and re-admission in 243, while 66 patients died (1.1%). Complications caused significantly longer LOS (20.08 vs 5.48 days) and higher economic cost (€11,670.31 vs €3,354.12); infectious complications were the most frequent and respiratory the most expensive (€20,428.53), together with ICU admission (€20,242.66). Clavien-Dindo grade correlated with greater LOS and costs (except gradev). During vacation periods, complications and LOS are increased, but costs of these complications and LOS did not differ significantly from complications detected in non-vacation periods.

    The principal objective of this paper is to identify the economic costs and benefits of pedophile treatment programs incorporating both the tangible and intangible cost of sexual abuse to victims. Cost estimates of cognitive behavioral therapy programs in Australian prisons are compared against the tangible and intangible costs to victims of being sexually abused. Estimates are prepared that take into account a number of problematic issues. These include the range of possible recidivism rates for treatment programs; the uncertainty surrounding the number of child sexual molestation offences committed by recidivists; and the methodological problems associated with estimating the intangible costs of sexual abuse on victims. Despite the variation in parameter estimates that impact on the cost-benefit analysis of pedophile treatment programs, it is found that potential range of economic costs from child sexual abuse are substantial and the economic benefits to be derived from appropriate and effective treatment programs are high. Based on a reasonable set of parameter estimates, in-prison, cognitive therapy treatment programs for pedophiles are likely to be of net benefit to society. Despite this, a critical area of future research must include further methodological developments in estimating the quantitative impact of child sexual abuse in the community.

    Full Text Available Abstract Background Asthma is one of the main non-infectious diseases of the respiratory system with substantial economic burden worldwide. The objective of this study was to estimate the economic burden of adult asthma in Cyprus during 2015. Methods A retrospective probabilistic prevalence-based cost of illness model was developed to calculate the economic burden of asthma including direct and indirect costs. The bottom-up approach (person-based data was used for the calculation of direct costs while for the calculation of indirect costs the approach of human capital was employed. In addition, bootstrapped sensitivity analysis with 1000 bootstrap simulations was performed in order to calculate a 95% Confidence Interval (CI. Results Mean patient cost of asthma in Cyprus in 2015 was estimated at €579.64 (95% CI: €376.90–€813.68. Direct costs accounted for 82.08% of the overall expenses, €475.75 per patient (95% CI: €296.94–€697.69. Indirect costs of €103.89 (95% CI: €49.59–€181.46 accounted for 17.92% of the overall expenses. Conclusion This was the first study in Cyprus, which used bootstrapped prevalence-based cost of illness model to estimate the cost of asthma. This study confirms that asthma is an expensive disease for the society. In addition, it provides important information and analysis of the economic consequences of asthma to policy makers in order to strengthen surveillance of the disease as well as draft the national health policy accordingly.

We argue that the theoretical model of neo-extractivism can explain the dynamics of social metabolism behind the North American Free Trade Agreement (NAFTA.

    Shifts at the international gas market indicate that the transaction cost perspective provides better underpinnings for European gas regulation than the current neoclassical perspective. Three implications are that policymakers should: (1) allow alternative coordination measures to complement market exchange; (2) recognize that less than perfect competition outcomes may be optimal and (3) be more reticent in prescribing interventionist measures. Finally, the analysis provides the foundations for the empirical research required to complement this paper's theoretical approach. (author)

    The ASEAN Economic Community (AEC) has been implemented since the beginning of 2016 and expected to be completed in 2025. The ASEAN member countries preserve their value and norms highly even in the condition of integrated ASEAN, particularly in state’s sovereignty, resulting “ASEAN Way” of integration. This research is conducted to compare the ASEAN Way of integration and theoretical kinds of economic integration (Balassa, 1961). Using GTAP 9 Migration database with 2007 and 2011 base year, ...

    Full Text Available Economic costs associated with the invasion of nonnative species are of global concern. We estimated expected costs of Chinese tallow (Triadica sebifera (L. Small invasions related to timber production in southern U.S. forestlands under different management strategies. Expected costs were confined to the value of timber production losses plus costs for search and control. We simulated management strategies including (1 no control (NC, and control beginning as soon as the percentage of invaded forest land exceeded (2 60 (Low Control, (3 25 (Medium Control, or (4 0 (High Control using a spatially-explicit, stochastic, bioeconomic model. With NC, simulated invasions spread northward and westward into Arkansas and along the Gulf of Mexico to occupy ≈1.2 million hectares within 20 years, with associated expected total costs increasing exponentially to ≈$300 million. With LC, MC, and HC, invaded areas reached ≈275, 34, and 2 thousand hectares after 20 years, respectively, with associated expected costs reaching ≈$400, $230, and $200 million. Complete eradication would not be cost-effective; the minimum expected total cost was achieved when control began as soon as the percentage of invaded land exceeded 5%. These results suggest the importance of early detection and control of Chinese tallow, and emphasize the importance of integrating spread dynamics and economics to manage invasive species.

    Energy investments in Poland are currently focused on supercritical coal-fired unit technology. It is likely, that in the future, these units are to be integrated with carbon capture and storage (CCS) installations, which enable a significant reduction of greenhouse gas emissions into the atmosphere. A significant share of the energy market in Poland is constituted by coal-fired combined heat and power (CHP) plants. The integration of these units with CCS installation can be economically inefficient. However, the lack of such integration enhances the investment risk due to the possibility of appearing on the market in the near future high prices of emission allowances. The aforementioned factors and additional favorable conditions for the development of cogeneration can cause one to consider investing in large supercritical CHP plants. This paper presents the results of an economic analysis aimed at comparing three cases of CHP plants, one without an integrated CCS installation and two with such installations. The same steam cycle structure for all variants was adopted. The cases of integrated CHP plants differ from each other in the manner in which they recover heat. For the evaluation of the respective solutions, the break-even price of electricity and avoided emission cost were used. - Highlights: • The simulations of operation of CHP plants under changing load have been realized. • For analyzed cases sensitivity analyses of economic indices have been conducted. • Conditions of competitiveness for integration with CCS units have been identified. • Integration can be profitable if prices of allowance will reach high values, exceeding 50 €/MgCO 2 . • Others important factors are the investment costs and operation and maintenance costs

    Highlights: • Integration of small MED unit with gas engine power cycle is studied in this paper. • Modeling, simulation, parametric study and sensitivity analysis were performed. • A thermodynamic model for heat recovery and power generation of the gas engine has been presented. • Annualized Cost of System (ACS) has been employed for economic assessment. • Economic feasibilty dependence of integrated system on natural gas and water prices has been investigated. - Abstract: Due to thermal nature of multi-effect desalination (MED), its integration with a suitable power cycle is highly desirable for waste heat recovery. One of the proper power cycle for proposed integration is internal combustion engine (ICE). The exhaust gas heat of ICE is used to produce motive steam for the required heat for the first effect of MED system. Also, the water jacket heat is utilized in a heat exchanger to pre-heat the seawater. This paper studies a thermodynamic model for a tri-generation system composed of ICE integrated with MED. The ICE thermodynamic model has been used in place of different empirical efficiency relations to estimate performance – load curves reasonably. The entire system performance has been coded in MATLAB, and the results of proposed thermodynamic model for the engine have been verified by manufacturer catalogue. By increasing the engine load from 40% to 100%, the water production of MED unit will increase from 4.38 cubic meters per day to 26.78 cubic meters per day and the tri-generation efficiency from 31% to 56%. Economic analyses of the MED unit integrated with ICE was performed based on Annualized Cost of System method. This integration makes the system more economical. It has been determined that in higher market prices for fresh water (more than 7 US$ per cubic meter), the increase in effects number is more significant to the period of return decrement.

    Gas-to-liquid (GTL) involves the chemical conversion of natural gas into synthetic crude that can be upgraded and separated into different useful hydrocarbon fractions including liquid transportation fuels. Such technology can also be used to convert other abundant natural resources such as coal and biomass to fuels and value added chemicals (referred to as coal-to-liquid (CTL) and biomass-to-liquid (BTL)). A leading GTL technology is the Fischer-Tropsch (FT) process. The objective of this work is to provide a techno-economic analysis of the GTL process and to identify optimization and integration opportunities for cost saving and reduction of energy usage while accounting for the environmental impact. First, a base-case flowsheet is synthesized to include the key processing steps of the plant. Then, a computer-aided process simulation is carried out to determine the key mass and energy flows, performance criteria, and equipment specifications. Next, energy and mass integration studies are performed to address the following items: (a) heating and cooling utilities, (b) combined heat and power (process cogeneration), (c) management of process water, (c) optimization of tail gas allocation, and (d) recovery of catalyst-supporting hydrocarbon solvents. Finally, these integration studies are conducted and the results are documented in terms of conserving energy and mass resources as well as providing economic impact. Finally, an economic analysis is undertaken to determine the plant capacity needed to achieve the break-even point and to estimate the return on investment for the base-case study. (author)

  3. A Hydro-Economic Approach to Representing Water Resources Impacts in Integrated Assessment Models

    2004-01-14

    Grant Number DE-FG02-98ER62665 Office of Energy Research of the U.S. Department of Energy Abstract Many Integrated Assessment Models (IAM) divide the world into a small number of highly aggregated regions. Non-OECD countries are aggregated geographically into continental and multiple-continental regions or economically by development level. Current research suggests that these large scale aggregations cannot accurately represent potential water resources-related climate change impacts. In addition, IAMs do not explicitly model the flow regulation impacts of reservoir and ground water systems, the economics of water supply, or the demand for water in economic activities. Using the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT) model of the International Food Policy Research Institute (IFPRI) as a case study, this research implemented a set of methodologies to provide accurate representation of water resource climate change impacts in Integrated Assessment Models. There were also detailed examinations of key issues related to aggregated modeling including: modeling water consumption versus water withdrawals; ground and surface water interactions; development of reservoir cost curves; modeling of surface areas of aggregated reservoirs for estimating evaporation losses; and evaluating the importance of spatial scale in river basin modeling. The major findings include: - Continental or national or even large scale river basin aggregation of water supplies and demands do not accurately capture the impacts of climate change in the water and agricultural sector in IAMs. - Fortunately, there now exist gridden approaches (0.5 X 0.5 degrees) to model streamflows in a global analysis. The gridded approach to hydrologic modeling allows flexibility in aligning basin boundaries with national boundaries. This combined with GIS tools, high speed computers, and the growing availability of socio-economic gridded data bases allows assignment of

    The construction of the models for biomass project development are described. These models, first constructed using QPRO electronic spread sheet for Windows, are now being developed with the aid of visual and object oriented program as tools using DELPHI V.1 for windows and process simulator SUPERPRO, V.2.7 Intelligent Inc. These models render the process development problems with economic objectives to be solved very rapidly. The preliminary analysis of cost and investments of biomass utilisation projects which are included for this study are: steam, ammonia, carbon dioxide and alkali pretreatment process, methane gas production using anaerobic digestion process, aerobic composting, ethanol fermentation and distillation, effluent treatments using high rate algae production as well as cogeneration of energy for drying. The main project under developments are the biomass valuation projects with the elephant (Napier) grass, sugar cane bagasse and microalgae, using models for mass balance, equipment and production cost. The sensibility analyses are carried out to account for stochastic variation of the process yield, production volume, price variations, using Monte Carlo method. These models allow the identification of economical and scale up problems of the technology. The results obtained with few preliminary project development with few case studies are reported for integrated project development for fuel and protein using process and cost simulation models.

    Before the January 1997 Record of Decision (ROD), the U.S. Department of Energy Office of Fissile Materials Disposition (DOE-MD) evaluated three technologies for the disposition of ∼50 MT of surplus plutonium from defense-related programs-reactors, immobilization, and deep boreholes. As part of the process supporting the ROD, and comprehensive assessment of technical viability, cost, and schedule was conducted by DOE-MD and its national laboratory contractors. Oak Ridge National Laboratory managed and coordinated the life-cycle cost (LCC) assessment effort for this program. This report discusses the economic analysis methodology and the results for the reactor options considered prior to ROD. A secondary intent of the report is to discuss major technical and economic issues that impact cost and schedule. To evaluate the economics of the reactor option and other technologies on an equitable basis, a set of cost-estimating guidelines and a common cost-estimating format were utilized by all three technology teams. This report includes the major economic analysis assumptions and the comparative constant-dollar and discounted-dollar LCCs for all nine reactor scenarios

    Full Text Available The objective of this paper is to learn about the effects of the adjustment costs, economic growth, imports and exports on human capital labor demand. The dynamic model proposed by Sargent (1978 was adjusted to consider three types of human capital: (a one with fundamental education (1–8 years of schooling; (b one with secondary education level (9–11 years of education; (c and one with tertiary education level (12 years or more of schooling. Using state level panel data, the dynamic econometrics estimates showed the following results: (i the labor market adjustment costs are very higher; (ii the adjustment cost for the human capital with intermediary education level is the highest one compared to the others; (iii the states’ economic growth favor those with superior education; (iv the imports seems to favor the demand for those with intermediate education levels; (v the degree of openness does show some weak effect on the demand for human capitals with intermediate education. In sum, the growing demand for human capital with some superior education seems to be more associated to its lower adjustment cost and economic growth; the non-significance of real wage elasticity and high adjustment cost seems to indicate that the human capital with intermediate knowledge is in short supply; hence, economic education policy that increases supply of such human capital are in need.

    In this paper we introduce capital transport cost in a unidimensional spatial Solow-Swan model of economic growth with capital-induced labor migration, considered in an unbounded domain. Proceeding with a stability analysis, we show that there is a critical value for the capital transport cost where the dynamic behavior of the economy changes, provided that the intensity of capital-induced labor migration is strong enough. On the one hand, if the capital transport cost is higher than this critical value, the spatially homogeneous equilibrium of coexistence of the model is stable, and the economy converges to this spatially homogeneous state in the long run; on the other hand, if transport cost is lower than this critical value, the equilibrium is unstable, and the economy may develop different spatio-temporal dynamics, including the formation of stable economic agglomerations and spatio-temporal economic cycles, depending on the other parameters in the model. Finally, numerical simulations support the results of the stability analysis, and illustrate the spatio-temporal dynamics generated by the model, suggesting that the economy as a whole benefits from the formation of economic agglomerations and cycles, with a higher capital transport cost reducing this gain.

    Despite their considerable interest for public health policies and for occupational disease management and assessment, the economic costs of asbestos-related diseases (ARDs) for society have not been fully estimated or even frequently discussed. The aim of this study was to estimate the economic burden of mesothelioma in Italy by assessing the overall societal cost of the disease, applying an econometric model. We analyzed two main cost groups, public and social. The first includes expenditure borne by the State and other public bodies (medical care costs, insurance, tax and benefits), while the latter uses the human capital approach to measure the loss of productivity suffered by the economy as a whole. We provide an estimate of euro 33,000 per patient for medical care costs and euro 25,000 for insurance and compensation; tax and benefits seem to roughly compensate. We estimated a loss of more than euro 200,000 per patient, in terms of loss of production. This study offers a practical approach for estimating the economic impact of mesothelioma, and provides empirical evidence of the huge economic burden linked to this disease, with its high etiologic fraction.

    On March 1979, a nuclear power station at Three-Mile Island (TMI) near Harrisburg, Pennsylvania, had a major breakdown. During the two-week period of the accident, about 150,000 residents were evacuated for reasons associated with safety and health. Many residents during and after the accident, regardless of whether they left or stayed, made mental and physical adjustments due to this accident. This paper is to estimate the economic costs incurred by individuals or communities as a result of a change in physical or mental health status and/or a change in health care services due to the TMI accident. The findings indicate that stress symptoms caused by the accident did affect the health-related behaviors of area residents. Of the costs examined, the economic costs of work days lost and physician visits are the largest cost items. There were some increases in consumption of alcohol, cigarettes, and tranquilizers immediately following the accident.

    In order to maintain and develop a universal health insurance system, it is crucial to utilize limited medical resources effectively. In this context, considerations are underway to introduce health technology assessments (HTAs), such as cost-effectiveness analyses (CEAs), into the medical treatment fee system. CEAs, which is the general term for these methods, are classified into four categories, such as cost-effectiveness analyses based on performance indicators, and in the comparison of health technologies, the incremental cost-effectiveness ratio (ICER) is also applied. When I comprehensively consider several Japanese studies based on these concepts, I find that, in the results of the analysis of the economic performance of healthcare systems, Japan shows the most promising trend in the world. In addition, there is research indicating the superior cost-effectiveness of Rituximab against refractory nephrotic syndrome, and it is expected that health economics will be actively applied to the valuation of technical innovations such as drug discovery.

    In a setting of economic and financial crisis, most companies experienced a reduction in their profitability. Thus, our study allows us to identify vertical integration strategies developed by companies to overcome the crisis. This paper is aimed at unveiling the determining factors of the profitability of Spanish agrifood firms, depending on whether they are backwards vertically integrated or not. In order to attain our objective, we implemented a first difference regression model. The main contributions of the article lie in the incorporation of a variable that distinguishes integrated firms from the rest and the separate analysis of the two groups of firms. The results suggest that firms that seek to differentiate themselves, either through offering a specific product or through providing higher quality with a view to maintaining their reputation, are more likely to adopt vertical integration due to the higher transaction costs of relations with suppliers. The grouping carried out in this study is shown to be highly relevant as asset structure implies different strategies for actions aimed at increasing profitability. (Author)

    2013-12-01

    Full Text Available INTRODUCTION In a situation when government expenditures for defense are more restrictive, any investment in the acquisition of arms and military equipment (AME is a question that does not allow errors in decisions. Accordingly, the economic analysis of the investment must be detailed and unavoidable. In the past, the initial cost of procurement of AME was often the primary, and sometimes the only one criterion in decision-making. Neglecting the analysis of costs throughout the life of assets in prefeasibility studies is the main cause of unplanned investment in the later stages of the life cycle of investment, and also of a number of problems in the functioning and unfulfilling or partially fulfilling the goals of the system. PROCESS OF EQUIPPING THE MoD AND THE SAF WITH AME Legislation governing the process of equipping the Ministry of Defence (MoD and the Serbian Armed Forces (SAF with AME is based on the Regulation on equipping the Yugoslav Army with weapons and military equipment in peacetime, from 1996, and on several Standards of National Defense (SNO 0477/83, SNO 1096/85, SNO 8196/92, SNO 9000/97, etc.. Due to a number of social and organizational changes in the defense system, this regulation is not in full compliance with real-time requirements. The analysis of legal regulations and activities in the process of equipping the MoD and the SAF with AME in practice indicates dominance of technical - technological aspects of the equipping analysis, while the economic aspect (primarily aspect of costs is present, but not detailed enough. At best, there is only a static approach to the analysis and evaluation of investment projects, while a dynamic aspect and the aspect of the total cost over the life of assets are not taken into account. ANALYSIS OF COSTS IN THE LIFETIME OF ASSETS Given the non-profit character of military organizations and the possibility to express explicit costs, but not the benefits of investment in equipping with AME

    Heart failure (HF) is a deadly, disabling and often costly syndrome world-wide. Unfortunately, there is a paucity of data describing its economic impact in sub Saharan Africa; a region in which the number of relatively younger cases will inevitably rise. Heath economic data were extracted from a prospective HF registry in a tertiary hospital situated in Abeokuta, southwest Nigeria. Outpatient and inpatient costs were computed from a representative cohort of 239 HF cases including personnel, diagnostic and treatment resources used for their management over a 12-month period. Indirect costs were also calculated. The annual cost per person was then calculated. Mean age of the cohort was 58.0 ± 15.1 years and 53.1% were men. The total computed cost of care of HF in Abeokuta was 76, 288,845 Nigerian Naira (US$508, 595) translating to 319,200 Naira (US$2,128 US Dollars) per patient per year. The total cost of in-patient care (46% of total health care expenditure) was estimated as 34,996,477 Naira (about 301,230 US dollars). This comprised of 17,899,977 Naira- 50.9% ($US114,600) and 17,806,500 naira -49.1%($US118,710) for direct and in-direct costs respectively. Out-patient cost was estimated as 41,292,368 Naira ($US 275,282). The relatively high cost of outpatient care was largely due to cost of transportation for monthly follow up visits. Payments were mostly made through out-of-pocket spending. The economic burden of HF in Nigeria is particularly high considering, the relatively young age of affected cases, a minimum wage of 18,000 Naira ($US120) per month and considerable component of out-of-pocket spending for those affected. Health reforms designed to mitigate the individual to societal burden imposed by the syndrome are required.

    The future evolution of energy supply technologies strongly depends on (and affects) the economic and environmental systems, due to the high dependency of this sector on the availability and cost of fossil fuels, especially on the small regional scale. This paper aims at presenting the modeling system and preliminary results of a research project conducted on the scale of Luxembourg to assess the environmental impact of future energy scenarios for the country, integrating outputs from partial and computable general equilibrium models within hybrid Life Cycle Assessment (LCA) frameworks. The general equilibrium model for Luxembourg, LUXGEM, is used to evaluate the economic impacts of policy decisions and other economic shocks over the time horizon 2006-2030. A techno-economic (partial equilibrium) model for Luxembourg, ETEM, is used instead to compute operation levels of various technologies to meet the demand for energy services at the least cost along the same timeline. The future energy demand and supply are made consistent by coupling ETEM with LUXGEM so as to have the same macro-economic variables and energy shares driving both models. The coupling results are then implemented within a set of Environmentally-Extended Input-Output (EE-IO) models in historical time series to test the feasibility of the integrated framework and then to assess the environmental impacts of the country. Accordingly, a dis-aggregated energy sector was built with the different ETEM technologies in the EE-IO to allow hybridization with Life Cycle Inventory (LCI) and enrich the process detail. The results show that the environmental impact slightly decreased overall from 2006 to 2009. Most of the impacts come from some imported commodities (natural gas, used to produce electricity, and metalliferous ores and metal scrap). The main energy production technology is the combined-cycle gas turbine plant 'Twinerg', representing almost 80% of the domestic electricity production in Luxembourg

    Reduction in smoking prevalence does not necessarily reduce the costs of smoking as evidence shows in developed countries. We provide up-to-date estimates for direct and indirect costs attributable to smoking in Hong Kong in 2011 and compare with our 1998 estimates. We took a societal perspective to include lives and life years lost, health care costs and time lost from work in the costing. We followed guidelines on estimating costs of active smoking for those aged 35 years or above (35+) and costs due to SHS exposure for 35+, infants aged 12 months and under and children aged 15 and below. All costs are in US$. We estimated that 6154 deaths among 35+ in Hong Kong in 2011 were attributable to active smoking, an increase of 10% from 1998. Besides, 672 deaths were attributable to SHS exposure, i.e. 10% of the total 6826 smoking-attributable deaths. The estimate of productive life lost due to deaths from active smoking by those aged under 65 years in 2011 was $166 million, an increase of about 4% over the estimate in 1998. Our conservative estimate of the annual tobacco-related disease cost in 2011 was $716 million which accounted for 0.3% of GDP. If we added the value of attributable lives lost, the annual cost would be $4.7 billion. Despite the reduction in smoking prevalence, smoking-attributable disease still imposes a substantial economic burden on Hong Kong society. These findings support more stringent and effective tobacco control legislation, polices and measures. Current evidence shows reduction in smoking prevalence does not necessarily reduce the economic costs of smoking. Most studies in developed countries employed a societal perspective, including costs of productivity loss and indirect costs, but not all studies estimated costs associated with second-hand smoking (SHS). The present study estimated the total costs of smoking in Hong Kong including direct and indirect costs attributable to active smoking and to SHS exposure. Our study confirms the

    Full Text Available BACKGROUND: Dengue illness causes 50-100 million infections worldwide and threatens 2.5 billion people in the tropical and subtropical regions. Little is known about the disease burden and economic impact of dengue in higher resourced countries or the cost-effectiveness of potential dengue vaccines in such settings. METHODS AND FINDINGS: We estimate the direct and indirect costs of dengue from hospitalized and ambulatory cases in Singapore. We consider inter alia the impacts of dengue on the economy using the human-capital and the friction cost methods. Disease burden was estimated using disability-adjusted life years (DALYs and the cost-effectiveness of a potential vaccine program was evaluated. The average economic impact of dengue illness in Singapore from 2000 to 2009 in constant 2010 US$ ranged between $0.85 billion and $1.15 billion, of which control costs constitute 42%-59%. Using empirically derived disability weights, we estimated an annual average disease burden of 9-14 DALYs per 100 000 habitants, making it comparable to diseases such as hepatitis B or syphilis. The proportion of symptomatic dengue cases detected by the national surveillance system was estimated to be low, and to decrease with age. Under population projections by the United Nations, the price per dose threshold for which vaccines stop being more cost-effective than the current vector control program ranged from $50 for mass vaccination requiring 3 doses and only conferring 10 years of immunity to $300 for vaccination requiring 2 doses and conferring lifetime immunity. The thresholds for these vaccine programs to not be cost-effective for Singapore were $100 and $500 per dose respectively. CONCLUSIONS: Dengue illness presents a serious economic and disease burden in Singapore. Dengue vaccines are expected to be cost-effective if reasonably low prices are adopted and will help to reduce the economic and disease burden of dengue in Singapore substantially.

    This paper deals with the economic impacts of the technical, environmental, and institutional barriers in the production, harvesting, and processing of various biomass fuels in California. For each biomass fuel, a base case scenario was developed to characterize the procedures of harvesting, processing and transporting. An economic model was utilized to project the biomass production costs supplied to direct-combustion power plants for each technical, environmental, and institutional barrier. These results will enable the California Energy Commission to identify the most significant barriers to economical biomass energy production (production, harvesting, and processing). (author)

    Obesity is not only a health but also an economic phenomenon with potentially important direct and indirect economic costs that are unlikely to be fully internalized by the obese. In the US, obesity prevalence is the highest among OECD countries and the issue has long been the focus of policy debate and academic research. However, European obesity rates are rising and there is still a lack of economic analysis of the obesity phenomenon in Europe. This paper attempts to fill in this gap by usi...

    There are no data on cost of neurosurgery in low-income and middle-income countries. The objective of this study was to estimate the cost of neurosurgical procedures in a low-resource setting to better inform resource allocation and health sector planning. In this observational economic analysis, microcosting was used to estimate the direct and indirect costs of neurosurgical procedures at Mulago National Referral Hospital (Kampala, Uganda). During the study period, October 2014 to September 2015, 1440 charts were reviewed. Of these patients, 434 had surgery, whereas the other 1006 were treated nonsurgically. Thirteen types of procedures were performed at the hospital. The estimated mean cost of a neurosurgical procedure was $542.14 (standard deviation [SD], $253.62). The mean cost of different procedures ranged from $291 (SD, $101) for burr hole evacuations to $1,221 (SD, $473) for excision of brain tumors. For most surgeries, overhead costs represented the largest proportion of the total cost (29%-41%). This is the first study using primary data to determine the cost of neurosurgery in a low-resource setting. Operating theater capacity is likely the binding constraint on operative volume, and thus, investing in operating theaters should achieve a higher level of efficiency. Findings from this study could be used by stakeholders and policy makers for resource allocation and to perform economic analyses to establish the value of neurosurgery in achieving global health goals.

  6. Large-scale offshore wind energy. Cost analysis and integration in the Dutch electricity market

    De Noord, M.

    1999-02-01

    the total construction time is reduced to 7 years. Different financing options are regarded: a required internal rate of return of 10% or even 5% reduces the kWh cost price with 27% up to 50%. The effect of including the lifetimes of components in the price calculations is analysed, as well as the effect of considering the electrical grid as part of the public grid. With a maximum public effort the kWh cost price could be reduced to 8 ct. Integration of large-scale offshore wind energy in the distribution system can cause several technical and economic effects. These effects are caused by the variable wind supply, and can vary from insufficient grid connection capacity to the potential danger of a black out in the distribution system and large price fluctuations on the electricity market. To solve these problems, the application of backup power is introduced. Three types are regarded: an old coal plant, a new STEG plant, and hydroelectric power from Norway. Calculations show a moderate effect on the wind energy price due to backup power: this price increases with 6% up to 13%. In the backup power calculations an assumed market price is used, which makes it possible to predict a provisional value of an OWE green certificate. Finally, a comparison is made between the effect of possible technology improvements, public incentive effects and the effect of using backup power. This results in the conclusion that the feasibility of large-scale offshore wind energy depends more on public policy than on technology. 22 refs

    2006-06-01

    Full Text Available Abstract Background Economic evaluations in the medical literature compare competing diagnosis or treatment methods for their use of resources and their expected outcomes. The best evidence currently available from research regarding both cost and economic comparisons will continue to expand as this type of information becomes more important in today's clinical practice. Researchers and clinicians need quick, reliable ways to access this information. A key source of this type of information is large bibliographic databases such as EMBASE. The objective of this study was to develop search strategies that optimize the retrieval of health costs and economics studies from EMBASE. Methods We conducted an analytic survey, comparing hand searches of journals with retrievals from EMBASE for candidate search terms and combinations. 6 research assistants read all issues of 55 journals indexed by EMBASE for the publishing year 2000. We rated all articles using purpose and quality indicators and categorized them into clinically relevant original studies, review articles, general papers, or case reports. The original and review articles were then categorized for purpose (i.e., cost and economics and other clinical topics and depending on the purpose as 'pass' or 'fail' for methodologic rigor. Candidate search strategies were developed for economic and cost studies, then run in the 55 EMBASE journals, the retrievals being compared with the hand search data. The sensitivity, specificity, precision, and accuracy of the search strategies were calculated. Results Combinations of search terms for detecting both cost and economic studies attained levels of 100% sensitivity with specificity levels of 92.9% and 92.3% respectively. When maximizing for both sensitivity and specificity, the combination of terms for detecting cost studies (sensitivity increased 2.2% over the single term but at a slight decrease in specificity of 0.9%. The maximized combination of terms

    Sub-Saharan Africa still reports the highest rates of under-five mortality. Low cost, high impact interventions exist, however poor access remains a challenge. Integrated community case management (iCCM) was introduced to improve access to essential services for children 2-59 months through diagnosis, treatment and referral services by community health workers for malaria, pneumonia and diarrhea. This paper presents the results of an economic analysis of iCCM implementation in regions supported by UNICEF in six countries and assesses country-level scale-up implications. The paper focuses on costs to provider (health system and donors) to inform planning and budgeting, and does not cover cost-effectiveness. The analysis combines annualised set-up costs and 1 year implementation costs to calculate incremental economic and financial costs per treatment from a provider perspective. Affordability is assessed by calculating the per capita financial cost of the program as a percentage of the public health expenditure per capita. Time and financial implications of a 30% increase in utilization were modeled. Country scale-up is modeled for all children under 5 in rural areas. Utilization of iCCM services varied from 0.05 treatment/y/under-five in Ethiopia to over 1 in Niger. There were between 10 and 603 treatments/community health worker (CHW)/y. Consultation cost represented between 93% and 22% of economic costs per treatment influenced by the level of utilization. Weighted economic cost per treatment ranged from US$ 13 (2015 USD) in Ghana to US$ 2 in Malawi. CHWs spent from 1 to 9 hours a week on iCCM. A 30% increase in utilization would add up to 2 hours a week, but reduce cost per treatment (by 20% in countries with low utilization). Country scale up would amount to under US$ 0.8 per capita total population (US$ 0.06-US$0.74), between 0.5% and 2% of public health expenditure per capita but 8% in Niger. iCCM addresses unmet needs and impacts on under 5 mortality.

    With increasing global energy demand and declining energy return on energy invested (EROEI) of crude oil, global energy consumption by the O&G industry has increased drastically over the past few years. In addition, this energy increase has led to an increase GHG emissions, resulting in adverse environmental effects. On the other hand, electricity generation through renewable resources have become relatively cost competitive to fossil based energy sources in a much ‘cleaner’ way. In this study, renewable energy is integrated optimally into a refinery considering costs and CO2 emissions. Using Aspen HYSYS, a refinery in the Middle East was simulated to estimate the energy demand by different processing units. An LP problem was formulated based on existing solar energy systems and wind potential in the region. The multi-objective function, minimizing cost as well as CO2 emissions, was solved using GAMS to determine optimal energy distribution from each energy source to units within the refinery. Additionally, an economic feasibility study was carried out to determine the viability of renewable energy technology project implementation to overcome energy requirement of the refinery. Electricity generation through all renewable energy sources considered (i.e. solar PV, solar CSP and wind) were found feasible based on their low levelized cost of electricity (LCOE). The payback period for a Solar CSP project, with an annual capacity of about 411 GWh and a lifetime of 30 years, was found to be 10 years. In contrast, the payback period for Solar PV and Wind were calculated to be 7 and 6 years, respectively. This opens up possibilities for integrating renewables into the refining sector as well as optimizing multiple energy carrier systems within the crude oil industry

    There is limited evidence about the extent to which sensitivity analysis has been used in the cost-effectiveness literature. Sensitivity analyses for health-related QOL (HR-QOL), cost and discount rate economic parameters are of particular interest because they measure the effects of methodological and estimation uncertainties. To investigate the use of sensitivity analyses in the pharmaceutical cost-utility literature in order to test whether a change in economic parameters could result in a different conclusion regarding the cost effectiveness of the intervention analysed. Cost-utility analyses of pharmaceuticals identified in a prior comprehensive audit (70 articles) were reviewed and further audited. For each base case for which sensitivity analyses were reported (n = 122), up to two sensitivity analyses for HR-QOL (n = 133), cost (n = 99), and discount rate (n = 128) were examined. Article mentions of thresholds for acceptable cost-utility ratios were recorded (total 36). Cost-utility ratios were denominated in US dollars for the year reported in each of the original articles in order to determine whether a different conclusion would have been indicated at the time the article was published. Quality ratings from the original audit for articles where sensitivity analysis results crossed the cost-utility ratio threshold above the base-case result were compared with those that did not. The most frequently mentioned cost-utility thresholds were $US20,000/QALY, $US50,000/QALY, and $US100,000/QALY. The proportions of sensitivity analyses reporting quantitative results that crossed the threshold above the base-case results (or where the sensitivity analysis result was dominated) were 31% for HR-QOL sensitivity analyses, 20% for cost-sensitivity analyses, and 15% for discount-rate sensitivity analyses. Almost half of the discount-rate sensitivity analyses did not report quantitative results. Articles that reported sensitivity analyses where results crossed the cost

    2014-01-01

    The main objective with this work was to investigate techno-economically the opportunity for integrated gasification-based biomass-to-methanol production in an existing chemical pulp and paper mill. Three different system configurations using the pressurized entrained flow biomass gasification (PEBG) technology were studied, one stand-alone plant, one where the bark boiler in the mill was replaced by a PEBG unit and one with a co-integration of a black liquor gasifier operated in parallel with a PEBG unit. The cases were analysed in terms of overall energy efficiency (calculated as electricity-equivalents) and process economics. The economics was assessed under the current as well as possible future energy market conditions. An economic policy support was found to be necessary to make the methanol production competitive under all market scenarios. In a future energy market, integrating a PEBG unit to replace the bark boiler was the most beneficial case from an economic point of view. In this case the methanol production cost was reduced in the range of 11–18 Euro per MWh compared to the stand-alone case. The overall plant efficiency increased approximately 7%-units compared to the original operation of the mill and the non-integrated stand-alone case. In the case with co-integration of the two parallel gasifiers, an equal increase of the system efficiency was achieved, but the economic benefit was not as apparent. Under similar conditions as the current market and when methanol was sold to replace fossil gasoline, co-integration of the two parallel gasifiers was the best alternative based on received IRR. - Highlights: • Techno-economic results regarding integration of methanol synthesis processes in a pulp and paper mill are presented. • The overall energy efficiency increases in integrated methanol production systems compared to stand-alone production units. • The economics of the integrated system improves compared to stand-alone alternatives. • Tax

  16. Benefits and costs of integrating technology into undergraduate nursing programs.

    Glasgow, Mary Ellen Smith; Cornelius, Frances H

    2005-01-01

    Advances in technology over the last decade have resulted in increased opportunities for educators to become more innovative in classroom and clinical teaching. These innovations have allowed students and faculty to access essential clinical information at the point of care/need. By capitalizing on technologies such as personal digital assistants and course delivery shells, faculty and students have both portable and remote access to information that can guide practice and learning activities in clinical, classroom, and distance settings. For instance, a student can use a personal digital assistant to research a patient's new medication at the bedside, study course information, access references during class in response to a question, or download clinical materials from home. Although the benefits of having ready access to information seem obvious, there are costs and strategic planning activities associated with implementing these projects. Clearly, the objective of any academic nursing program is to develop skills among students so they can efficiently access information and use that information to guide their nursing practice. To do so, academic nursing administrators must have the forethought to envision how new technologies can support achieving this goal as well as the ability to put in place the infrastructure supports needed for success. This article presents a case study of how one institution developed the necessary infrastructure and garnished the appropriate resources to implement an ambitious technology initiative integrated throughout a large undergraduate nursing program. In addition, how the integration of technology, online and mobile, can enhance clinical learning will be discussed.

    The MONITOR model is a FORTRAN 77 based computer code that provides parametric life-cycle cost estimates for a monitored retrievable storage (MRS) facility. MONITOR is very flexible in that it can estimate the costs of an MRS facility operating under almost any conceivable nuclear waste logistics scenario. The model can also accommodate input data of varying degrees of complexity and detail (ranging from very simple to more complex) which makes it ideal for use in the MRS program, where new designs and new cost data are frequently offered for consideration. MONITOR can be run as an independent program, or it can be interfaced with the Waste System Transportation and Economic Simulation (WASTES) model, a program that simulates the movement of waste through a complete nuclear waste disposal system. The WASTES model drives the MONITOR model by providing it with the annual quantities of waste that are received, stored, and shipped at the MRS facility. Three runs of MONITOR are documented in this report. Two of the runs are for Version 1 of the MONITOR code. A simulation which uses the costs developed by the Ralph M. Parsons Company in the 2A (backup) version of the MRS cost estimate. In one of these runs MONITOR was run as an independent model, and in the other run MONITOR was run using an input file generated by the WASTES model. The two runs correspond to identical cases, and the fact that they gave identical results verified that the code performed the same calculations in both modes of operation. The third run was made for Version 2 of the MONITOR code. A simulation which uses the costs developed by the Ralph M. Parsons Company in the 2B (integral) version of the MRS cost estimate. This run was made with MONITOR being run as an independent model. The results of several cases have been verified by hand calculations

    Current evidence suggests that chlamydia screening programmes can be cost-effective, conditional on assumptions within mathematical models. We explored differences in cost estimates used in published economic evaluations of chlamydia screening from seven countries (four papers each from UK and the Netherlands, two each from Sweden and Australia, and one each from Ireland, Canada and Denmark). From these studies, we extracted management cost estimates for seven major chlamydia sequelae. In order to compare the influence of different sequelae considered in each paper and their corresponding management costs on the total cost per case of untreated chlamydia, we applied reported unit sequelae management costs considered in each paper to a set of untreated infection to sequela progression probabilities. All costs were adjusted to 2013/2014 Great British Pound (GBP) values. Sequelae management costs ranged from £171 to £3635 (pelvic inflammatory disease); £953 to £3615 (ectopic pregnancy); £546 to £6752 (tubal factor infertility); £159 to £3341 (chronic pelvic pain); £22 to £1008 (epididymitis); £11 to £1459 (neonatal conjunctivitis) and £433 to £3992 (neonatal pneumonia). Total cost of sequelae per case of untreated chlamydia ranged from £37 to £412. There was substantial variation in cost per case of chlamydia sequelae used in published chlamydia screening economic evaluations, which likely arose from different assumptions about disease management pathways and the country perspectives taken. In light of this, when interpreting these studies, the reader should be satisfied that the cost estimates used sufficiently reflect the perspective taken and current disease management for their respective context.

    In 2008, 2·45 million people were diagnosed with cancer and 1·23 million died because of cancer in the 27 countries of the European Union (EU). We aimed to estimate the economic burden of cancer in the EU. In a population-based cost analysis, we evaluated the cost of all cancers and also those associated with breast, colorectal, lung, and prostate cancers. We obtained country-specific aggregate data for morbidity, mortality, and health-care resource use from international and national sources. We estimated health-care costs from expenditure on care in the primary, outpatient, emergency, and inpatient settings, and also drugs. Additionally, we estimated the costs of unpaid care provided by relatives or friends of patients (ie, informal care), lost earnings after premature death, and costs associated with individuals who temporarily or permanently left employment because of illness. Cancer cost the EU €126 billion in 2009, with health care accounting for €51·0 billion (40%). Across the EU, the health-care costs of cancer were equivalent to €102 per citizen, but varied substantially from €16 per person in Bulgaria to €184 per person in Luxembourg. Productivity losses because of early death cost €42·6 billion and lost working days €9·43 billion. Informal care cost €23·2 billion. Lung cancer had the highest economic cost (€18·8 billion, 15% of overall cancer costs), followed by breast cancer (€15·0 billion, 12%), colorectal cancer (€13·1 billion, 10%), and prostate cancer (€8·43 billion, 7%). Our results show wide differences between countries, the reasons for which need further investigation. These data contribute to public health and policy intelligence, which is required to deliver affordable cancer care systems and inform effective public research funds allocation.

    There is no standard treatment pathway for tinnitus patients in the UK. Possible therapies include education and reassurance, cognitive behavioural therapies, modified tinnitus retraining therapy (education and sound enrichment), or amplification of external sound using hearing aids. However, the effectiveness of most therapies is somewhat controversial. As health services come under economic pressure to deploy resources more effectively there is an increasing need to demonstrate the value of tinnitus therapies, and how value may be continuously enhanced. The objective of this project was to map out existing clinical practice, estimate the NHS costs associated with the management approaches used, and obtain initial indicative estimates of cost-effectiveness. Current treatment pathways, costs and health outcomes were determined from the tinnitus literature, national statistics, a patient survey, and expert opinion. These were used to create an Excel-based economic model of therapy options for tinnitus patients. The probabilities associated with the likelihood of an individual patient receiving a particular combination of therapies was used to calculate the average cost of treatment per patient, average health outcome per patient measured in QALYs gained, and cost-effectiveness, measured by the average cost per QALY gained. The average cost of tinnitus treatment per patient per year is GB£717, equating to an NHS healthcare bill of GB£750 million per year. Across all pathways, tinnitus therapy costs £10,600 per QALY gained. Results were relatively insensitive to restrictions on access to cognitive behaviour therapy, and a subsequent reliance on other therapies. NHS provisions for tinnitus are cost-effective against the National Institute for Health and Care Excellence cost-effective threshold. Most interventions help, but education alone offers very small QALY gains. The most cost-effective therapies in the model were delivered within audiology.

    To estimate direct and indirect economic costs among private-sector employees with osteoarthritis (OA). Using a large US employer benefits database, we identified all employees with evidence of OA during calendar year 2007, and compared their costs of health care and work loss to age-and-sex-matched employees without evidence of OA in that year. Private-sector employees with OA (n = 2399) averaged 62.9 days of absenteeism versus 36.7 days among matched comparators (n = 2399) (P Private-sector employees with OA have higher direct and indirect costs than those without this condition.

  2. REFCO83, Nuclear Fuel Cycle Cost Economics Using Discounted Cash Flow Analysis

    1 - Description of program or function: REFCO83 utilizes a discounted cash flow (DCF) analysis procedure to calculate batch, cycle, and lifetime levelized average nuclear fuel cycle costs. The DCF analysis establishes an energy 'cost' associated with the fuel by requiring that the revenues from the sale of energy be adequate to pay the required return on outstanding capital, to pay all expenses including taxes, and to retire the outstanding investment to zero by the end of the economic life of the set of fuel investments. The program uses reactor mass flow information together with individual fuel cost parameters and utility capital structure and money costs to calculate levelized costs cumulatively through any batch or cycle. 2 - Method of solution: A fuel cycle cost component is considered to be any fuel material purchase, processing cost, or discharge material credit in the complete fuel cycle. The costs for each individual component, i.e. uranium, enrichment, etc., may either be expensed or capitalized for tax purposes or, in the case of waste disposal, the cost may also be made proportional to power production. To properly account for the effect of income taxes, all calculations in REFCO83 are done using 'then' current dollars, including price escalations caused by inflation. The database used for the default values for REFCO83 was taken from the Nuclear Energy Cost Data Base. 3 - Restrictions on the complexity of the problem: The maximum number of fuel batches is 120

    Recently, the estimation of accident costs within the social costs of nuclear power plants (NPPs) has garnered substantial interest. In particular, the risk aversion behavior of the public toward an NPP accident is considered an important factor when integrating risk aversion into NPP accident cost. In this study, an integrated framework for the external cost assessment of NPP accident that measures the value of statistical life (VSL) and the relative risk aversion (RRA) coefficient for NPP accident based on an individual-level survey is proposed. To derive the willingness to pay and the RRA coefficient for NPP accident risks, a survey was conducted on a sample of 1550 individuals in Korea. The estimation obtained a mean VSL of USD 2.78 million and an RRA coefficient of 1.315. Based on the estimation results in which various cost factors were considered, a multiplication factor of 5.16 and an external cost of NPP accidents of 4.39E−03 USD-cents/kW h were estimated. This study is expected to provide insight to energy policy decision-makers on analyzing the economic validity of NPP compared to other energy sources by reflecting the estimated external cost of NPP accident into the unit electricity generation cost of NPP. - Highlights: •External cost assessment framework for NPP is proposed considering risk aversion. •VSL was derived from WTP for mortality risk reduction from hypothetical NPP accident. •RRA was derived to integrate public risk aversion into external cost of NPP accident. •Individual-level survey was conducted to derive WTP and RRA for NPP accident risk. •The external cost was estimated considering the direct cost factors of NPP accident.

    The availability of energy resources is a central point to economic development. The energy matrix of most countries is based on the consumption of fossil fuels, which adds annually over 5 billion tons of carbon into the atmosphere. The energy consumption in developing countries has quadrupled since the 60s further aggravating global environmental conditions. The need to implement alternative energy sources to the energy matrix was proved. In addition, Brazil has a large number of people without access to electricity, which affects the quality of life of these populations. In this context, it is necessary to think in economic development way, and then the sustainable and alternative sources appear as an option for its features and its availability in Brazil. The solar energy captured by photovoltaic cells can be highlighted in the Brazilian scenario because of its wide availability, especially in the Northeast. The aim of this paper is to estimate the economic feasibility of insertion of solar systems in small communities in the Brazilian Northeast, considering environmental costs involved in electricity generation. The methodology is based on economic concepts and economic valuation of environmental resources. The results shows that solar power is becoming increasingly competitive due to reduced costs of components and due to the environmental costs reduced when compared with fossil fuels. (author)

    PPG pursued the development of an integrated substrate, including the anode, external, and internal extraction layers. The objective of PPG's program was to achieve cost reductions by displacing the existing expensive borosilicate or double-side polished float glass substrates and developing alternative electrodes and scalable light extraction layer technologies through focused and short-term applied research. One of the key highlights of the project was proving the feasibility of using PPG's high transmission Solarphire® float glass as a substrate to consistently achieve organic lightemitting diode (OLED) devices with good performance and high yields. Under this program, four low-cost alternatives to the Indium Tin Oxide (ITO) anode were investigated using pilot-scale magnetron sputtered vacuum deposition (MSVD) and chemical vapor deposition (CVD) technologies. The anodes were evaluated by fabricating small and large phosphorescent organic lightemitting diode (PHOLED) devices at Universal Display Corporation (UDC). The device performance and life-times comparable to commercially available ITO anodes were demonstrated. A cost-benefit analysis was performed to down-select two anodes for further low-cost process development. Additionally, PPG developed and evaluated a number of scalable and compatible internal and external extraction layer concepts such as scattering layers on the outside of the glass substrate or between the transparent anode and the glass interface. In one external extraction layer (EEL) approach, sol-gel sprayed pyrolytic coatings were deposited using lab scale equipment by hand or automated spraying of sol-gel solutions on hot glass, followed by optimizing of scattering with minimal absorption. In another EEL approach, PPG tested large-area glass texturing by scratching a glass surface with an abrasive roller and acid etching. Efficacy enhancements of 1.27x were demonstrated using white PHOLED devices for 2.0mm substrates which are

    Skin conditions and dermatological diseases associated with advanced age (e.g. fungal infection, dry skin and itch) receive increasingly attention in clinical practice and research. Cost and economic evaluations are important sources to inform priority setting and ressource allocation decisions in healthcare. The economics of skin conditions in aged populations has not been systematically reviewed so far. The aim of this mapping review was to summarize the economic evidence of selected skin conditions in the aged (65 + years). A mapping literature review and evidence summary was conducted. Searches were conducted in data bases Medline and Embase via OVID. Cinahl was searched using EBSCO. References lists of potential eligible studies, reviews, guidelines or other sources were screened for additional literature. For evaluation of methodological quality of full economic analyses the Consensus on Health Economic Criteria (CHEC) checklist was used. Database searches resulted in 1388 records. A total of 270 articles were read in full-text. Thirty-five publications were finally included in the data analysis reporting 38 economic analyses. Ten cost of illness analyses and 26 cost-effectiveness analyses reporting about pressure ulcers, skin tears, pressure ulcers, incontinence associated dermatitis and intertrigo/contact dermatitis/candidiasis treatment and prevention and onychomycosis testing were identified. Limited evidence indicated that low air loss beds were more cost effective than standard beds for prevention of pressure ulcers. Standardized skin care regimens seem to lower the incidence of pressure ulcers, skin tears and IAD but a cost saving effect was not always observed. Findings of this mapping review indicate that there is a paucity of high quality evidence regarding the economic impact of age-associated skin conditions and diseases. Substantial heterogeneity in terms of study design, evaluation perspective, time period, and way of cost estimation was

    Clostridium difficile infection (CDI) is the most important cause of healthcare-associated infectious diarrhea in industrialized countries. We performed a literature review of the overall economic burden of initial and recurrent CDI as well as of the cost-effectiveness of the various treatment strategies applied in these settings. Even though analysis of health economic data is complicated by the limited comparability of results, our review identified several internationally consistent results. Authors from different countries have shown that recurrent CDI disproportionally contributes to the overall economic burden of CDI and therefore offers considerable saving potential. Subsequent cost-effectiveness analyses almost exclusively identified fidaxomicin as the preferred treatment option for initial CDI and fecal microbiota transplant (FMT) for recurrent CDI. Among the various FMT protocols, optimum results were obtained using early colonoscopy-based FMT. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Mining enrichment enterprises of the ferrous and nonferrous metallurgy, coal and chemical industry have much in common in the area of technology of production, technical base, organization of labor and production. This in turn presupposes the possible development of a common procedure of accounting of expenditures for production, calculation of net cost of output and analysis of production-economic activity of enterprises. Based on scientific research and generalization of advanced experience of practical workers, means of improvement of economic operation in mining enrichment enterprises are outlined according to increasing demands of production control. An outline of analytic accounting of expenditures which provides for multitarget use of information has been developed: for organization of operational control of the formulation of net cost of output, determination of the results of self support activities of structural subdivisions of an enterprise, computation of the efficiency of scientific and technical progress. Experience of use of economic and mathematical methods in computers for this purpose is discussed.

    In the past three years there have been several key events or changes that can lead to fully economic, massive deployment to the grid-connected and central PV markets. The factors discussed in this report include: (1) significant cost reduction in single crystal and polycrystal silicon so that modules profitably priced at $3.10-$3.30 per peak watt and installed grid-connected systems with installed cost of $5.50 per watt are being offered; (2) several new thin film plants - amorphous silicon, cadmium telluride, and copper indium diselenide are being built for 1996, 1997 production with greatly reduced costs; (3) government subsidized volume orders for PV in grid-connected houses (Japan, Germany, Switzerland, Italy, and the United States) provide volume (2000+ units per year) that lead to reduced costs; (4) environmental benefits for PV are being applied in Europe and Japan permitting 'early adopters' to enter the market; and (5) government and commercial acceptance of PV building integrated products, especially in Europe, are expanding PV markets. The combination of these forces lead to the prediction that an 'accelerated' market mode could start in the year 2000

    This paper addresses the issue of biases in cost measures which used in economic evaluation studies. The basic measure of hospital costs which is used by most investigators is unit cost. Focusing on this measure, a set of criteria which the basic measures must fulfil in order to approximate the marginal cost (MC) of a service for the relevant product, in the representative site, was identified. Then four distinct biases--a scale bias, a case mix bias, a methods bias and a site selection bias--each of which reflects the divergence of the unit cost measure from the desired MC measure, were identified. Measures are proposed for several of these biases and it is suggested how they can be corrected.

    The therapeutic workplace is a novel intervention that uses access to paid training and employment to reinforce drug abstinence within the context of standard methadone maintenance. We used the Drug Abuse Treatment Cost Analysis Program as a standard method of estimating the economic costs of this intervention. Over a one-year period, the therapeutic workplace served 122 methadone maintenance clients who had a median length of stay of 22 weeks. The workplace maintained a mean daily census of 48 clients. The combined cost of methadone maintenance and the therapeutic workplace was estimated at $362 per week. This cost is less than other treatments that might be used to promote abstinence in individuals who continue to use drugs during methadone treatment. Given prior evidence of effectiveness, these cost data may be useful to policymakers, social service agencies, and researchers interested in using or further developing the therapeutic workplace intervention.

    Nowadays, solid waste management continues to be a major challenge in urban areas, especially in developing country. It is triggered by population growth, economic growth, industrialization and urbanization. Indonesia itselfs categorized into developing country. Indonesia's government has many program in order to increase the economic growth. One of them is MP3EI (Masterplan Percepatan dan Perluasan Pembangunan Ekonomi Indonesia. This program should be suppported by right waste management system. If Indonesia's waste management system can't afford the economic growth, it will trigger health and environmental problems. This study's purpose is to develop the socio-economic-environment model that can be used as a basis planning for the facility and cost of waste management systems. In this paper we used the development of Khajuria model test method. This method used six variables, which are GDP, population, population density, illiteracy, school's period and economic growth. The result showed that development of Khajuria test could explained the influence of economic and demographic factors to waste generation, 65.6%. The projection of waste generation shows that Pangkalpinang, Pekanbaru and Serang are the cities with the highest waste generation for the next five years. The number of dump truck and TPS in DKI Jakarata is the highest within another city, which is 39.37%. For the next five years, the waste management system in our study areas cost maximum 0.8% from GDP (Gross Domestic Products).

    Background Rabies is a zoonotic disease that, in most human cases, is fatal once clinical signs appear. The disease transmits to humans through an animal bite. Dogs are the main vector of rabies in humans on Flores Island, Indonesia, resulting in about 19 human deaths each year. Currently, rabies control measures on Flores Island include mass vaccination and culling of dogs, laboratory diagnostics of suspected rabid dogs, putting imported dogs in quarantine, and pre- and post-exposure treatment (PET) of humans. The objective of this study was to estimate the costs of the applied rabies control measures on Flores Island. Methodology/principal findings A deterministic economic model was developed to calculate the costs of the rabies control measures and their individual cost components from 2000 to 2011. The inputs for the economic model were obtained from (i) relevant literature, (ii) available data on Flores Island, and (iii) experts such as responsible policy makers and veterinarians involved in rabies control measures in the past. As a result, the total costs of rabies control measures were estimated to be US$1.12 million (range: US$0.60–1.47 million) per year. The costs of culling roaming dogs were the highest portion, about 39 percent of the total costs, followed by PET (35 percent), mass vaccination (24 percent), pre-exposure treatment (1.4 percent), and others (1.3 percent) (dog-bite investigation, diagnostic of suspected rabid dogs, trace-back investigation of human contact with rabid dogs, and quarantine of imported dogs). Conclusions/significance This study demonstrates that rabies has a large economic impact on the government and dog owners. Control of rabies by culling dogs is relatively costly for the dog owners in comparison with other measures. Providing PET for humans is an effective way to prevent rabies, but is costly for government and does not provide a permanent solution to rabies in the future. PMID:24386244

    Highlights: • Cascade utilization of low- and mid-temperature geothermal energy is presented. • The system consists of three thermal levels producing power, ice and useful heat. • A techno-economic analysis is performed evaluating energy and economic benefits. • A simple optimization algorithm was developed to optimize system benefits. • Inconvenience of low thermal efficiency and high capital cost of ORC were overcome. - Abstract: The Organic Rankine Cycle (ORC) is a technology that has reached maturity in cogeneration or waste heat applications. However, due to low thermal efficiency and high capital cost of ORC machines, geothermal-based ORC applications represent only a small percent sharing of the geothermal power capacity worldwide. Several countries have reported a great potential of low- and mid-temperature geothermal energy, representing an opportunity to explore a more efficient ORC integration into non-conventional applications of geothermal energy. One alternative, resembling the polygeneration concept, is known as cascade utilization of geothermal energy, where different energy outputs or products can be obtained at the same time, while improving thermal and economic performance. In this paper, a techno-economic analysis for the selection of small capacity ORC machines and absorption chillers (for ice production), to be integrated into a polygeneration plant that makes use of geothermal energy in a cascade arrangement, is presented. A simple cascade system that consists of three sequential thermal levels, producing simultaneously power, ice and useful heat is proposed, considering typical temperatures of geothermal zones in Mexico. A simple optimization algorithm, based on energy and economic models, including binary variables and manufacturer’s data, was developed to evaluate and determine optimal ORC and absorption chiller units. Results show, firstly, that inconvenience of low thermal efficiency and high capital cost of ORC machines can

    Blood disorders comprise a wide range of diseases including anaemia, malignant blood disorders, and haemorrhagic disorders. Although they are a common cause of disease, no systematic cost-of-illness studies have been done to assess the economic effect of non-malignant blood disorders in Europe. We aimed to assess the economic burden of non-malignant blood disorders across the 28 countries of the European Union (EU), Iceland, Norway, and Switzerland. Non-malignant blood disorder-related costs (WHO International Classification of Diseases, 10th revision [ICD] D50-89) were estimated for 28 EU countries, Iceland, Norway, and Switzerland for 2012. Country-specific costs were estimated with aggregate data on morbidity, mortality, and health-care resource use obtained from international and national sources. Health-care costs were estimated from expenditure on primary care, outpatient care, emergency care, hospital inpatient care, and drugs. Costs of informal care and productivity losses due to morbidity and early death were also included. To these costs we added those due to malignant blood disorders (ICD-10 C81-96 and D47) as estimated in a Burns and colleagues' companion Article to obtain the total costs of blood disorders. Non-malignant disorders of the blood cost the 31 European countries €11 billion in 2012. Health-care costs accounted for €8 billion (75% of total costs), productivity losses for €2 billion (19%), and informal care for less than €1 billion (6%). Averaged across the European population studied, non-malignant disorders of the blood represented an annual health-care cost of €159 per ten citizens. Combining malignant and non-malignant blood disorders, the total cost of blood disorders was €23 billion in 2012. Our study highlights the economic burden that non-malignant blood disorders place on European health-care systems and societies. Our study also shows that blood disorder costs were evenly distributed between malignant and non

    Full Text Available One aim of higher education is to develop professional identities in students to equip them for future working life. Health professional students will work under financial pressures in a market-based environment, which can lead to conflicts with professional ethical values. This study explores how Swedish dental students perceive economic aspects of dentistry. The article is based on a study of undergraduate research projects. In the analysis of the projects, two themes were identified: (1 cost-effective organizing of dentistry and (2 costs and benefits of interventions. The students displayed socially responsible values by emphasizing the need for dentists to utilize resources effectively, which implies that professional education can support the development of the perception that economic values can be compatible with professional ethical values.Keywords: cost-effectiveness, ethics, healthcare, higher education, social responsibility

    Full Text Available A methodology of evaluating the economics of the front-end nuclear fuel cycle with a price change sensitivity analysis for a VVER-1000 reactor core as a case study is presented. The effect of increasing the fuel enrichment and its corresponding reactor cycle length on the energy cost is investigated. The enrichment component was found to represent the highly expenses dynamic component affecting the economics of the front-end fuel cycle. Nevertheless, the increase of the fuel enrichment will increase the reactor cycle length, which will have a positive feedback on the electricity generation cost (cent/KWh. A long reactor operation time with a cheaper energy cost set the nuclear energy as a competitive alternative when compared with other energy sources.

    To estimate resource use and costs associated with peripartum hysterectomy for the English National Health Service. Analysis of linked Clinical Practice Research Datalink and Hospital Episodes Statistics (CPRD-HES) data. Women undergoing peripartum hysterectomy between 1997 and 2013 and matched controls. Inverse probability weighted generalised estimating equations were used to model the non-linear trend in healthcare service use and costs over time, accounting for missing data, adjusting for maternal age, body mass index, delivery year, smoking and socio-economic indicators. Primary care, hospital outpatient and inpatient attendances and costs (UK 2015 prices). The study sample included 1362 women (192 cases and 1170 controls) who gave birth between 1997 and 2013; 1088 (153 cases and 935 controls) of these were deliveries between 2003 and 2013 when all categories of hospital resource use were available. Based on the 2003-2013 delivery cohort, peripartum hysterectomy was associated with a mean adjusted additional total cost of £5380 (95% CI £4436-6687) and a cost ratio of 1.76 (95% CI 1.61-1.98) over 5 years of follow up compared with controls. Inpatient costs, mostly incurred during the first year following surgery, accounted for 78% excluding or 92% including delivery-related costs. Peripartum hysterectomy is associated with increased healthcare costs driven largely by increased post-surgery hospitalisation rates. To reduce healthcare costs and improve outcomes for women who undergo hysterectomy, interventions that reduce avoidable repeat hospitalisations following surgery such as providing active follow up, treatment and support in the community should be considered. A large amount of NHS data on peripartum hysterectomy suggests active community follow up could reduce costs, #HealthEconomics. © 2017 Royal College of Obstetricians and Gynaecologists.

    Full Text Available Target costing by integrating customer requirements, technical attributes and cost information into the product design phase and eliminating the non-value added functions, plays a vital role in different phases of the product life cycle. Quality Function Deployment (QFD and Value Engineering (VE are two techniques which can be used for applying target costing, successfully. The purpose of this paper is to propose an integrated model of target costing, QFD and VE to explore the role of target costing in managing product costs while promoting quality specifications meeting customers’ needs. F indings indicate that the integration of target costing, QFD and VE is an essential technique in managing the costs of production process. Findings also imply that integration of the three techniques provides a competitive cost advantage to companies.

    We study the link between corruption and economic integration. We show that if an economic union establishes a common regulation for public procurement, the country more prone to corruption benefits more from integration. However, if the propensities to corruption are too distinct, the less corrupt country will not be willing to join the union. This difference in corruption propensities can be offset by a difference in efficiency. We also show that corruption is lower if integration occurs. A...

    Full Text Available Objective to substantiate the need for economic integration of agricultural enterprises. Methods abstractlogical monographic. Results economic integration in agriculture is needed due to the destruction of economic relations in the period of economy liberalization and decrease in efficiency and productivity in agriculture. The solution to the problems of financing pricing and marketing of agricultural products lies in the sphere of forming integrative relations between enterprises producing processing and marketing agricultural products. Basing on the analysis of theoretical provisions the main forms of enterprises integration is identified such as contractual relationship without creating new legal entities formation of associations unions holding companies financialindustrial groups. It was found that the most effective are those forms of associations that form a complete closed cycle of production and sales i.e. holdings and financialindustrial groups. Basing on the analysis of the economic integration principles the necessity was determined of implementing the principle of stability of economic relations which will allow to overcome the crisis in the agrarian sector. In addition the author has formulated principles for the implementing the economic mechanism in integrated groups based on equality freedom and integrity of such groups. The key components of economic relations in terms of integration were identified ndash organizational unity of the technological process as well as the transformation of the interests of technologically related actors towards a common result. Scientific novelty the principle of stability of economic links during integration of agricultural enterprises was formulated. The necessity was proved of integrating the enterprises providing comparable levels of capacity utilization and the possibility of complete product sales as well as the necessity of forming integration relations as a single object of ownership

  10. Comparative economic analysis of the Integral Molten Salt Reactor and an advanced PWR using the G4-ECONS methodology

    The assessment of economic viability of a new reactor concept is crucial particularly during the early stages of its concept development. The G4-ECONS methodology provides a standardized top-down estimate of electricity cost and parametric sensitivities, not specifically targeted toward an accurate prediction of the final cost when deployed, but rather seeking an approximation of cost variations relative to other systems. This study presents an analysis of the Integral Molten Salt Reactor (IMSR) concept in comparison with a consistent analysis of an advanced PWR reactor (represented by AP1000). Estimation of levelized unit electricity costs, as well as sensitivity analyses to the discount rate and uranium or SWU prices, are presented using this methodology.

    Clinical pathways (CPW) are considered safe and effective at decreasing postoperative length of stay (LoS), but the effect on economic costs is uncertain. This study sought to elucidate the effect of a CPW on direct hospitalization costs for patients undergoing pancreaticoduodenectomy (PD). A CPW for PD patients at a single Canadian institution was implemented. Outcomes included LoS, 30-day readmissions, and direct costs of hospital care. A retrospective cost minimization analysis compared patients undergoing PD prior to and following CPW implementation, using a bootstrapped t test and deviation-based cost modeling. 121 patients undergoing PD after CPW implementation were compared to 74 controls. Index LoS was decreased following CPW implementation (9 vs. 11 days, p = 0.005), as was total LoS (10 vs. 11 days, p = 0.003). The mean total cost of postoperative hospitalization per patient decreased in the CPW group ($15,678.45 CAD vs. $25,732.85 CAD, p = 0.024), as was the mean 30-day cost including readmissions ($16,627.15 CAD vs. $29,872.72 CAD, p = 0.016). Areas of significant cost savings included laboratory tests and imaging investigations. CPWs may generate cost savings by reducing unnecessary investigations, and improve quality of care through process standardization and decreasing practice variation.

    A hardware random number generator is different from a pseudo-random number generator; a pseudo-random number generator approximates the assumed behavior of a real hardware random number generator. Simple pseudo random number generators suffices for most applications, however for demanding situations such as the generation of cryptographic keys, requires an efficient and a cost effective source of random numbers. Arbiter-based Physical Unclonable Functions (PUFs) proposed for physical authentication of ICs exploits statistical delay variation of wires and transistors across integrated circuits, as a result of process variations, to build a secret key unique to each IC. Experimental results and theoretical studies show that a sufficient amount of variation exits across IC"s. This variation enables each IC to be identified securely. It is possible to exploit the unreliability of these PUF responses to build a physical random number generator. There exists measurement noise, which comes from the instability of an arbiter when it is in a racing condition. There exist challenges whose responses are unpredictable. Without environmental variations, the responses of these challenges are random in repeated measurements. Compared to other physical random number generators, the PUF-based random number generators can be a compact and a low-power solution since the generator need only be turned on when required. A 64-stage PUF circuit costs less than 1000 gates and the circuit can be implemented using a standard IC manufacturing processes. In this paper we have presented a fast and an efficient random number generator, and analysed the quality of random numbers produced using an array of tests used by the National Institute of Standards and Technology to evaluate the randomness of random number generators designed for cryptographic applications.

    For a detailed understanding of the effects of climate change on global agricultural production systems, it is essential to consider the variability of climate change patterns as projected by General Circulation Models (GCMs), their bio-physical impact on crops and the response in land-use patterns and markets. So far, approaches that account for the interaction of bio-physical and economic impacts are largely lacking. We present an integrative analysis by using a soft-coupled system of a biophysical impact model (LPJmL, Bondeau et al. 2007), an economically driven land use model (MAgPIE, Lotze-Campen et al. 2008) and an integrated assessment model (ReMIND-R, Leimbach et al. 2010) to study climate change impacts and economic damages in the agricultural sector. First, the dynamic global vegetation and hydrology model LPJmL is used to derive climate change impacts on crop yields for wheat, maize, soy, rice and other major crops. A range of different climate projections is used, taken from the dataset provided by the Intersectoral Impact Model Intercomparison Project (ISI-MIP, www.isi-mip.org), which bias-corrected the latest CMIP5 climate data (Taylor et al. 2011). Crop yield impacts cover scenarios with and without CO2 f
