    A model program for green pricing targeted primarily at large customers is proposed in this paper. The program would create a partnership between a local community group, a renewables advocacy group, and several Colorado utilities. The first part of the paper summarizes pertinent background issues, including utility experience with green pricing programs. The rest of the paper outlines the program proposal, focusing primarily on organizational structure.

  2. Effective Drinking Water Pricing, A Case Study of Arak City

    Full Text Available Drinking water pricing is a major challenge facing the water and wastewater industry in Iran where decisions of water pricing are essentially based on social, legal, administrative, and financial criteria with only a slight heed, if any, paid to economic considerations. Generally speaking, the price of water in Iran reflects a percentage fraction of the costs of water production and distribution while an economterically efficient model of water pricing is absent. This failure to account for economic considerations in water pricing has turned water into a commodity supplied either at a very low price or free of charge in cases. The current situation of water scarcity which is complicated by a multitude of environmental problems can only be ascribed to the present water pricing policies. It is, therefore, essential for the water sector to employ economic tools, adopt relevant approaches, and execute optimized strategic policies in an attempt to reduce the negative impacts of the imminent water crisis. Based on the above considerations, the present study was designed to investigate and review optimal water pricing policies at Arak Water and Wastewater Authority which functions as a business offering both domestic and non-domestic water services. The cost function considered is a translog one and the seemingly unrelated regressions are used for estimation. Results show that the domestic water price levied from customers covers only 33% of the total production and delivery costs such that Arak Water & Wastewater Authority practices the economy of scale in producing both domestic and non-domestic water. Considering the fact that pricing based on the marginal cost under the conditions of economy of scale leads to financial losses for Arak W&W Authority, it seems appropriate to calculate the second best price as suggested by Frank Ramsey. Thus, the marginal cost was combined with the price elasticity for the domestic water demand in the different

    This article aims to define a value-based approach to pricing and reimbursement for off-patent originators using a multiple criteria decision analysis (MCDA) approach centered on a systematic analysis of current pricing and reimbursement policies in China. A drug price policy review was combined with a quantitative analysis of China's drug purchasing database. Policy preferences were identified through a MCDA performed by interviewing well-known academic experts and industry stakeholders. The study findings indicate that the current Chinese price policy includes cost-based pricing and the establishment of maximum retail prices and premiums for off-patent originators, whereas reference pricing may be adopted in the future. The literature review revealed significant differences in the dissolution profiles between originators and generics; therefore, dissolution profiles need to be improved. Market data analysis showed that the overall price ratio of generics and off-patent originators was around 0.54-0.59 in 2002-2011, with a 40% price difference, on average. Ten differentiating value attributes were identified and MCDA was applied to test the impact of three pricing policy scenarios. With the condition of implementing quality consistency regulations and controls, a reduction in the price gap between high-quality off-patent products (including originator and generics) seemed to be the preferred policy. Patents of many drugs will expire within the next 10 years; thus, pricing will be an issue of importance for off-patent originators and generic alternatives.

    2011-01-01

    Full Text Available Inflationary moments, characterized by significant price rises, have proved that accountingsystems based on historical costs provide a distorted image of the reality: the elements ofthe balance sheet are under-valuated, and the stock-related expenses and amortization in theprofit and loss account are also under-valuated. Under these circumstances, the result isover-valuated, and its distribution leads to allotments from the company’s capital. In thispaper we draw up a case study with regards to the methods used for adjusting pricemodification, clearly outlining, through a comparative analysis, the main differencesbetween the accounting system based on historical cost and inflation accounting.

  6. The Combination Forecasting of Electricity Price Based on Price Spikes Processing: A Case Study in South Australia

    2014-01-01

    Full Text Available Electricity price forecasting holds very important position in the electricity market. Inaccurate price forecasting may cause energy waste and management chaos in the electricity market. However, electricity price forecasting has always been regarded as one of the largest challenges in the electricity market because it shows high volatility, which makes electricity price forecasting difficult. This paper proposes the use of artificial intelligence optimization combination forecasting models based on preprocessing data, called “chaos particles optimization (CPSO weight-determined combination models.” These models allow for the weight of the combined model to take values of [-1,1]. In the proposed models, the density-based spatial clustering of applications with noise (DBSCAN algorithm is used to identify outliers, and the outliers are replaced by a new data-produced linear interpolation function. The proposed CPSO weight-determined combination models are then used to forecast the projected future electricity price. In this case study, the electricity price data of South Australia are simulated. The results indicate that, while the weight of the combined model takes values of [-1,1], the proposed combination model can always provide adaptive, reliable, and comparatively accurate forecast results in comparison to traditional combination models.

    District heating markets are often dominated by monopolies in both Denmark and Finland. The same companies, often owned by local municipalities, are usually operating both supplying plants and district heating networks, while the pricing mechanisms are rigid, often agreed upon for one year...... in advance. The mentioned ownership scheme may cause problems, when one tries to gain a third party access in order to deliver excess heat or heat from cheaper heating plants. In this paper, two case studies were carried out to simulate the district heating systems based on dynamic pricing. Case studies were...... carried out for Sønderborg, Denmark and Espoo, Finland. The results showed that dynamic pricing fosters feeding the waste heat into the grid, as dynamic pricing reduced the total primary energy consumption and CO2 emissions in both case studies. In the best scenarios, the weighted average heat price...

    Full Text Available The transfer price is basically the price used for transfer of tangible and intangible assets between related parties and it should be determined on the basis of market value without being influenced by the relationship of affiliation. However, if for services or tangible assets, the comparison of the transfer price to the market one is relatively easy to achieve, for the intangible ones, quantifying future benefits waived by the affiliated person compared to the situation in which it would be independent is harder to be established.

    1994-01-01

    Pakistan, a developing country, has gone through various phases of formulating gas pricing policies during its 40-year history of natural gas production and consumption. This paper identifies critical factors that influenced gas pricing policies in Pakistan and adverse effects experienced when any of these factors was not given proper consideration. For instance, on the producer's side, discounted pricing formulas discouraged further exploration and development, leaving high-potential areas unexplored and discovered fields dormant for more than a decade. On the consumer's side, subsidized gas prices encouraged consumption to rise steeply without new discoveries to offset additional surplus consumption. The paper also discusses various short- and long-term variables that should go into a gas pricing policy for developing countries. References to recent policies are also given, indicating how these variables were incorporated in real terms. The conclusions and recommendations, based on Pakistan's long experience with the gas industry, should be useful for other oil-importing countries rich in indigenous gas resources

  10. Can voluntary pooled procurement reduce the price of antiretroviral drugs? a case study of Efavirenz.

    : A number of strategies have aimed to assist countries in procuring antiretroviral therapy (ARV) at lower prices. In 2009, as the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) commenced a voluntary pooled procurement scheme, however, the impact of the scheme on ARV prices remains uncertain. This study aims to estimate the effect of VPP on drug prices using Efavirenz as a case study. This analysis uses WHO Global price report mechanism (GPRM) data from 2004 to 2013. Due to the highly skewed distribution of drug Prices, a generalized linear model (GLM) was used to conduct a difference-in-difference estimation of drug price changes over time. These analyses found that voluntary pooled procurement reduced both the ex-works price of generic Efavirenz and the incoterms price by 16.2 and 19.1%, respectively ( P <  0.001) in both cases). The year dummies were also statistically significant from 2006 to 2013 ( P <  0.001), indicating a strong decreasing trend in the price of Efavirenz over that period. Voluntary pooled procurement significantly reduced the price of 600 mg generic Efavirenz between 2009 and 2013. Voluntary pooled procurement therefore offers a potentially effective strategy for the reduction in HIV drug prices and the improvement of technical efficiency in HIV programming. Further work is required to establish if these findings hold also for other drugs. © The Author 2017.

    2009-10-01

    To characterize the patterns of competition for a sample of drugs in the Portuguese pharmaceutical market before (January 2002-March 2003) and after (April 2003-June 2003) the introduction of the reference pricing system (RPS). We performed a descriptive, retrospective, longitudinal analysis, with monthly observations from January 2002 until June 2003 of 15 homogeneous groups. The groups represented the upper limit of public pharmaceutical expenditure in the RPS segment in 2003 (n=270). Measures of competition were: 1) number of presentations; 2) prescriptions' concentration in the generic and originator (brand) segments, using Herfindahl-Hirschman Index (HHI); and 3) dominant positions of market leader in the homogeneous group. A correlation analysis between the number of presentations, the HHI, and the dominant position of the market leader was performed using Pearson coefficient of correlation. The structure of the market changed with the introduction of RPS. We found an increasing number of generic presentations (from 4+/-3 to 7+/-4; mean+/-standard deviation) and a decrease in the HHI for the generics market segment (from 0.7+/-0.2 to 0.6+/-0.3). There was a negative correlation between those variables that increased after the introduction of RPS (from -0.6 to -0.8). The HHI for brands and the dominant positions remained unchanged. After the implementation of RPS, the increased competition was mainly driven by economic and social agents in the generics market segment but not in the brands market segment.

    The increase in the price of goods is often a concern among the community. This is caused by factors that beyond of controlled such as a natural disaster, and others that cause the demand exceed the current supply. However, what is more concerning is the increase in price of goods due to the individual who raises the price in order to earn higher profits. Therefore, to overcome this problem, a method of price controls using Game Theory is considered. The Game Theory realizing a form of observational on the action and effects that occur by an individual or group to maximize the utilization under certain circumstances. The study was conducted on prices of 14 fish commodities in the state of Terengganu and also to see the cooperation effect between players of commodity prices. Data were analysed by using the software Gambit. The result shows that there is significant increase due to the influence of middlemen. The findings also shows that the price controls are applied at a set time, then it was applied to other times, prices are more stable and profitable returns to all parties can be maximized.

  14. Dilemmas of Transfer Pricing Comparability Analysis in Manufacturing Entities. Polish-Czech Case Study

    2018-06-01

    Modern manufacturing entities often operate in capital groups, and their role is sometimes limited to the function of cost centers. From the legal point of view, however, they are separate entities obliged to apply transfer pricing regulations. Meeting the requirements of the arm's length principle can be very difficult at this time, given the relationships and conflicts of interest in the capital group. Complexity increases in capital groups operating in different countries, due to differences in tax regulations. The main purpose of the paper is to demonstrate that the need to valuate the sale of finished goods to a manufacturing entity, which is a subject to a different tax jurisdiction, may lead to a problem of compliance with the arm's length principle. In addition, the paper proposes a methodology for comparability analysis that may be used by manufacturing entities to defend conditions of setting transfer pricing. The paper presents the different functional profiles of manufacturing entities and points out the difficulties that they may encounter when preparing the comparability analysis. It has also been noted that there are differences in transfer pricing regulations in different countries, for example by analyzing Polish and Czech regulations. The lack of uniform benchmarking legislation can cause inconsistencies in the selection of comparable data, resulting in differences in transfer pricing. The paper uses the method of legal regulation review and analysis of results of published studies concerning the scope of transfer pricing and comparability analysis. The paper also adopts a case study analysis.

    Chili is one of the important agricultural commodity in Indonesia because of its widely consumption by the Indonesian. Chili becomes one of the commodities that experience price fluctuations and important cause of yearly inflation in Indonesia. The unstable price of chili is affected by the scarcity of the commodity in some months and the difference of the harvest season. This study proposes a model to solve the problem by considering the substitution of fresh chilies with dried chili. We propose the cooperative of chili's farmer as entities that process fresh chili into dry ones. The existence of substitution products is expected to maintain the price stability chili. This research was conducted by taking a case study on chili commodity markets in Surakarta which consists of 19 traditional markets. This study aims to create a price stabilization scheme with product substitution using a game theory model. There are 4 strategies proposed in game theory model to describe the relationship between producers and consumers. In this case, the producers are the farmers and the consumers are the trade market. A mixed strategy of was chosen to determine the optimal value among 4 strategies. From the calculation results obtained optimal value when doing a mixed strategy of IDR 201,188,829,000.

    The effects of oil-price shocks on the macroeconomic performance of a non-oil-producing, oil-importing state are studied in terms of Hawaii's experience (1974-1986) using Vector Autoregression (VAR). The VAR model contains three macrovariables-real oil price, interest rate, and real GNP, and three regional variable-total civilian labor force, Honolulu consumer price index, and real personal income. The results suggested that oil-price shock had a positive effect on interest rate as well as local price (i.e., higher interest and higher local price), but a negative influence on real GNP. The negative income effect, however, was offset by the positive employment effect. The price of oil was found to be exogenous to all other variables in the system. The macrovariables exerted a pronounced impact on Hawaii's economy, most notably on consumer price

  17. The price of snow: albedo valuation and a case study for forest management

    Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they have yet to be contrasted in a case study with implications for future forest management. Here we utilize four methodologies for calculating a shadow price for albedo radiative forcing and apply the resulting eight prices to an ecological and economic forest model to examine the effects on optimal rotation periods on two different forest stands in the White Mountain National Forest in New Hampshire, USA. These pricing methodologies produce distinctly different shadow prices of albedo, varying from a high of 9.36 × 10 −4 and a low of 1.75 × 10 −5 $w −1 yr −1 in the initial year, to a high of 0.019 and a low of 3.55 × 10 −4 $w −1 yr −1 in year 200 of the simulation. When implemented in the forest model, optimal rotation periods also varied considerably, from a low of 2 to a high of 107 years for a spruce-fir stand and from 35 to 80 years for a maple-beech-birch stand. Our results suggest that the choice of climate metrics and pricing methodologies for use with forest albedo alter albedo prices considerably, may substantially adjust optimal rotation period length, and therefore may have consequences with respect to forest land cover change.

    2011-01-01

    The global warming and climate change have put enormous pressure on both governments and industries to re-think their attitudes and behaviours towards sustainability issues. The past decades have witnessed a number of renewable energy developments across the world. Even though these developments are not issue-free, it is generally recognized that the benefits outweigh disadvantages. However, there is an increasing level of concern on the high initial cost associated with the renewable energies, which was claimed as one of critical barriers to the promotion of its further developments. A case study approach is adopted in this study to investigate the pricing and affordability issues associated with the renewable energy in China. The policy framework and related statistics are critically reviewed in order to discuss these issues from different stakeholders' perspective in Shandong province, China. It is concluded that the affordability remains a critical issue despite numerous efforts have been made by the Chinese Government and Shandong Provincial Government on renewable power pricing. This study offers a useful reference to pricing and affordability of renewable energy. (author)

  19. Price discrimination in obstetric services--a case study in Bangladesh.

    Amin, Mohammad; Hanson, Kara; Mills, Anne

    2004-06-01

    This article examines the existence of price discrimination for obstetric services in two private hospitals in Bangladesh, and considers the welfare consequences of such discrimination, i.e. whether or not price discrimination benefited the poorer users. Data on 1212 normal and caesarean section patients discharged from the two hospitals were obtained. Obstetric services were chosen because they are relatively standardised and the patient population is relatively homogeneous, so minimising the scope and scale of product differentiation due to procedure and case-mix differences. The differences between the hospital list price for delivery and actual prices paid by patients were calculated to determine the average rate of discount. The welfare consequences of price discrimination were assessed by testing the differences in mean prices paid by patients from three income groups: low, middle and high. The results suggest that two different forms of price discrimination for obstetric services occurred in both these hospitals. First, there was price discrimination according to income, with the poorer users benefiting from a higher discount rate than richer ones; and second, there was price discrimination according to social status, with three high status occupational groups (doctors, senior government officials, and large businessmen) having the highest probability of receiving some level of discount.

  1. Perceptions of Water Pricing during a Drought: A Case Study from South Australia

    Directory of Open Access Journals (Sweden)

    John Martin

    2013-02-01

    Full Text Available This paper examines the perceptions of urban and regional water consumers in three areas of South Australia on the fairness of the water pricing system, the impact of increases in water pricing on households and pricing as a driver of water conservation. The study was conducted in 2009 during a time of severe drought and mandatory water restrictions. The results did not show a general aversion to all aspects of price increases but rather different sectors of the population were particularly resistant to different, specific aspects of water pricing. A state-wide water pricing policy in South Australia means that all consumers pay the same rate per volume of water consumed regardless of their location; yet in the regional study area, where it costs more for the service provider to supply the water, the respondents had stronger feelings that the price of water should be higher in places where it costs more to supply it. Generally, low income earners were less in favor of a block pricing system than higher income earners. The latter findings indicate a common lack of awareness around various aspects of water pricing. Some implications of the findings for water managers are outlined.

    Following the global trend, India declared its biofuel policy in which biodiesel, primarily from jatropha, would meet 20% of the diesel demand beginning with 2011-2012. To promote biofuel, Indian government has announced biodiesel purchase price as well as compulsory blending ratio. But, these measures have not worked to create large scale biodiesel production in India. With this backdrop, this paper highlights about the importance of a sound pricing policy focusing on the entire value chain of biodiesel production. The analysis is based on field level data from Chhattisgarh, the leading state in the production of jatropha. Such a sound pricing policy has to deal with the prices of feedstock, by-products and final product like biodiesel. It would also have to reflect on the business model of production of biodiesel. The simulation exercises in our model shows that the business returns from the production of biodiesel and the minimum support price (MSP) of the feedstock for biodiesel (i.e. jatropha seeds in this case) are sensitive to various parameters like seed yields, technological efficiency, by product and petro-diesel prices. An effective price policy framework has to consider all these factors to create a platform for sustainable biodiesel production in India. (author)

    2011-01-01

    Full Text Available Urban decay is an inevitable outcome of the growth of most cities, including Hong Kong. Many old buildings in Hong Kong are dilapidated, and it is urgent to tackle urban decay in the city. Redeveloping dilapidated buildings has long been regarded as an effective solution to this urban problem. Yet, as suggested in the literature, redevelopment may be responsible for gentrifying neighbourhoods because it pushes up property and rental prices near redeveloped sites. However, there are still few empirical studies on how comprehensive redevelopment affects housing values in a neighbourhood. In this light, this study investigates the impacts of the Urban Renewal Authority’s Argyle Street / Shanghai Street Redevelopment Project on the transaction prices of nearby housing. A set of panel data is employed and the change in the spatial price gradient before and after the redevelopment project is explored. The findings suggest that proximity to the project site had a significant positive impact on housing prices before the project. However, no change was seen in the spatial price gradient after completion of the project. These results confirm the findings of a previous study that housing prices do not respond to the change in the environmental quality resulting from comprehensive redevelopment.

This paper seeks to fill this gap in the literature, especially from a combined marketing-economic perspective. Especially the paper's main objective is to identify the determinants of non-price competition in the port sector and evaluate their effect on various aspects of non-price competition. We start with a general conceptual framework to explain how competition in the sector can be affected by various factors and then propose an analytical framework on non-price competition. The analytical model is then used to support the design of a survey questionnaire. Next, hypothesis tests are conducted using exploratory factor analysis (EFA and structural equation modeling (SEM and data collected from a survey of Turkish ports. Based on the analysis results, the implications for port management and future research are also discussed.

  8. Relationship Between Energy Prices, Monetary Policy and Inflation; A Case Study of South Asian Economies

    Directory of Open Access Journals (Sweden)

    Atiq-ur-Rehman

    2014-01-01

    Full Text Available Monetary policy tools, including money supply and interest rate, are the most popular instruments to control inflation around the globe. It is assumed that a tight monetary policy, either in form of reduction in money supply or an increase in interest rate, will reduce inflation by reducing aggregate demand in an economy. However, monetary policy could be counterproductive if cost side effects of monetary tightening prevail. High energy prices may increase the cost of production by reducing aggregate supply in the economy. If tight monetary policy is used to reduce this cost push inflation, the cost side effect of energy prices will add to cost side effects of monetary tightening and will become dominant. In this case, the monetary policy could be counterproductive. Furthermore, simultaneous reduction in aggregate supply and aggregate demand will bring twofold reduction in output. Therefore greater care is needed in the use of monetary policy in the situation of cost push inflation. This article investigates the presence of cost side effect of monetary transmission mechanism, the role of international oil prices in domestic inflation, and implications for monetary policy. The findings suggest that both monetary policy and oil prices have cost side effects on inflation and monetary tightening could be counterproductive if used to reduce energy pushed inflationary trend.

The proposed intervention is that the company create new cost centers, use costing methods, assessment criteria and form your price based on the markup taking into account the market price.

  10. A study of Canadian retail gasoline prices

    International Nuclear Information System (INIS)

    Eckert, A.L.

    1999-05-01

    Retail gasoline pricing in Canadian markets was examined to demonstrate why retail prices tend to follow one of two distinct patterns and that neither pattern is observable in the wholesale price. In many cities, retail prices are more rigid than wholesale prices, while in other markets, retail prices follow a cyclic pattern not seen in wholesale prices. This study examined why constant prices are observed in some cities, while other cities have cyclic prices. Theoretical justification was given to the argument that prices will remain constant only in markets in which there are only few gasoline companies with a small number of stations, but a large per-station capacity. It was shown that when one firm operates significantly more stations than its rival, a constant cost equilibrium cannot be maintained. However, a cycle equilibrium can be constructed in this case, and also when the two companies are similarly sized. An initial examination of available price, cost and market structure data shows that there is a positive correlation between price stability and concentration. The response of retail prices to wholesale price movements in the presence of a retail price cycle was also examined through the use of a simple model based on the predictions of the above theory. Data for the city of Windsor, Ontario was used for the modelling approach. A new cycle is created by an increase in price whenever the distance between the previous retail price and the current wholesale prices is very small. Retail prices are more responsive to wholesale prices over the increasing portion of the cycle. It was shown that when the asymmetric error correction model of Borenstein, Cameron and Gilbert is estimated, it indicates a more rapid response to wholesale price increases than to decreases. 72 refs., 22 tabs., 8 figs

    The Irish Government is considering its future targets, policy and programmes for renewable energy for the period beyond 2005. This follows a review in 2003 of policy options that identified a number of different measures to stimulate increased deployment of renewable energy generation capacity. This paper expands this review with an economic analysis of renewable energy price support mechanisms in the Irish electricity generation sector. The focus is on three primary price support mechanisms quota obligations, feed in tariffs and competitive tender schemes. The Green-X computer model is utilised to characterise the RES-E potential and costs in Ireland up until, and including, 2020. The results from this dynamic software tool are used to compare the different support mechanisms in terms of total costs to society and the average premium costs relative to the market price for electricity. The results indicate that in achieving a 20% RES-E proportion of gross electricity consumption by 2020, a tender scheme provides the least costs to society over the period 2006-2020 but only in case there is limited or no strategic bidding. Considering, however, strategic bidding, a feed-in tariff can be the more efficient solution. Between the other two support mechanisms, the total costs to society are highest for feed-in-tariffs (FIT) until 2013, at which point the costs for the quota system begin to rise rapidly and overtake FIT in 2014-2020. The paper also provides a sensitivity analysis of the support mechanism calculations by varying default parameters such as the interim (2010) target, the assumed investment risk levels and the amount of biomass co-firing. This analysis shows that a 2010 target of 15% rather than 13.2% generates lower costs for society over the whole period 2006-2020, but higher costs for the RES-E strategy over the period 2006-2010

    Spinks, Jean M; Richardson, Jeff R J

    2011-08-01

    This article considers the pricing policy for pharmaceuticals in Australia, which is widely seen as having achieved low drug prices. However, compared to New Zealand, the evidence implies that Australia might have improved its performance significantly if it had proactively sought market best pricing. The Australian record suggests that the information sought by authorities may not be sufficient for optimal pricing and that the economic evaluation of pharmaceuticals may be neither necessary nor sufficient for achieving this goal.

  15. Comparative Analysis of Discovery Function of Cotton Future Price among Different Regions——A Case Study of Xinjiang

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    Through comparative analysis, We research the relationship between cotton future price and cotton spot price in different regions, in order to formulate corresponding strategies in different regions under the new situation. We use ADF unit root test, E-G two-step cointegration test, Granger causality test, and other research methods in Eviews 5.0 statistical software, to empirically study the relationship between the cotton future price and cotton spot price in Xinjiang, the relationship between the cotton future price and cotton spot price in China. The results show that there is a long-term relationship between the cotton future price and cotton spot price in Xinjiang, between the cotton future price and cotton spot price in China; the cotton future price plays unidirectional role in guiding cotton spot price in Xinjiang and cotton spot price in China. The discovery function of cotton future price plays much greater role in the cotton market of China than in the cotton market of Xinjiang.

    Full Text Available Considering that agricultural sector is the largest consumer of water, presenting integrated management for water resources and formulating effective policies to increase water productivity in this sector is essential. Therefore, using economic modeling , this study simulated the farmers’ responses to irrigation water pricing and rationing policies in Zabol city. To achieve the study purpose, the State Wide Agricultural Production Model and Positive Mathematical Programming were applied. The required data for the years 2010-2011 was collected by completing questionnaires and collecting data sets from the relevant agencies of Zabol city in personal attendance. The results showed that imposing irrigation water pricing and rationing policies in Zabol city leads to a reduction in the total cultivated area by 9/54 and 5/14 percent and a reduction in the water consumption by 6/23 and 7/01 percent, compared to the base year. Ultimately, irrigation water rationing policy, considering frugality of 18/9 million m3 of water, as the appropriate solution for the sustainability of water resources of Zabol city was proposed.

    Highlights: •Uncertainty over overlapping energy and climate policies affects investment choices. •An integrated real options and portfolio optimisation model is used in a case study. •Interacting carbon pricing and renewable supports can create private and social hedge. •Political uncertainty may justify overlapping carbon pricing and renewable supports. -- Abstract: The translation of a greenhouse gas (GHG) emissions reduction policy objective to the required investment in low emissions technologies may be hindered by political contest over the policy instruments employed to achieve it. Political contest may also result in enactment of overlapping policy instruments which, from a ‘policy purist’ perspective, may not appear well calibrated to a shared GHG emissions reduction objective. This paper reports insights gained from an integrated real options and portfolio optimisation model of electricity generation investment behaviour under political uncertainty over the futures of interacting carbon pricing and renewable portfolio standard (RPS) instruments. We compare modelling results and actual outcomes in Australia, where an emission reduction target has had bipartisan support but the means to achieve it has not, to test the assertion that overlapping policy instruments must always increase the social costs of GHG abatement. Results suggest that overlapping a politically contested carbon pricing policy with an RPS may result in a lower risk, renewable energy (RE) investment environment, as the overlap allows investors to hedge their portfolio against political uncertainty through RE additions. Consequently, GHG abatement objectives may be achieved at lower cost than would be the case without the policy interaction. The policies overlap can provide a ‘safety valve’ or ‘hedge’ to both private investors and policymakers when deep uncertainties over the future of energy and climate policies influence investment strategies.

  2. Global Phosphorus Fertilizer Market and National Policies: A Case Study Revisiting the 2008 Price Peak

    Directory of Open Access Journals (Sweden)

    Nikolay Khabarov

    2017-06-01

    Full Text Available The commodity market super-cycle and food price crisis have been associated with rampant food insecurity and the Arab spring. A multitude of factors were identified as culprits for excessive volatility on the commodity markets. However, as it regards fertilizers, a clear attribution of market drivers explaining the emergence of extreme price events is still missing. In this paper, we provide a quantitative assessment of the price spike of the global phosphorus fertilizer market in 2008 focusing on diammonium phosphate (DAP. We find that fertilizer market policies in India, the largest global importer of phosphorus fertilizers and phosphate rock, turned out to be a major contributor to the global price spike. India doubled its import of P-fertilizer in 2008 at a time when prices doubled. The analysis of a wide set of factors pertinent to the 2008 price spike in phosphorus fertilizer market leads us to the discovery of a price spike magnification and triggering mechanisms. We find that the price spike was magnified on the one hand by protective trade measures of fertilizer suppliers leading to a 19% drop in global phosphate fertilizer export. On the other hand, the Indian fertilizer subsidy scheme led to farmers not adjusting their demand for fertilizer. The triggering mechanism appeared to be the Indian production outage of P-fertilizer resulting in the additional import demand for DAP in size of about 20% of annual global supply. The main conclusion is that these three factors have jointly caused the spike, underscoring the need for ex ante improvements in fertilizer market regulation on both national and international levels.

  3. A monopoly pricing model for diffusion maximization based on heterogeneous nodes and negative network externalities (Case study: A novel product

    Aghdas Badiee

    2018-10-01

    Full Text Available Social networks can provide sellers across the world with invaluable information about the structure of possible influences among different members of a network, whether positive or negative, and can be used to maximize diffusion in the network. Here, a novel mathematical monopoly product pricing model is introduced for maximization of market share in noncompetitive environment. In the proposed model, a customer’s decision to buy a product is not only based on the price, quality and need time for the product but also on the positive and negative influences of his/her neighbors. Therefore, customers are considered heterogeneous and a referral bonus is granted to every customer whose neighbors also buy the product. Here, the degree of influence is directly related to the intensity of the customers’ relationships. Finally, using the proposed model for a real case study, the optimal policy for product sales that is the ratio of product sale price in comparison with its cost and also the optimal amounts of referral bonus per customer is achieved.

    2017-09-01

    When the European Commission, International Monetary Fund and European Central Bank arrived in Cyprus to assist for a sustainable solution on the crisis on the banking sector, one of the first things they ordered was a New General Valuation (a mass appraisal that would revalue all properties in Cyprus as on 1st of January 2013), that it would be used for taxation purposes. The above indicates the importance of property mass appraising tools. This task was successfully conducted by the Department of Lands and Surveys. Authors aim to move a step further and implement the use of GIS and GWR techniques to improve the results of the New General Valuation. On a sample of comparative evidences for flats in Nicosia District, GIS was used to measure the impact of spatial attributes on real estate prices and to construct a prediction model in terms of spatially estimating apartment values. In addition to the structural property characteristics, some spatial attributes (landmarks) were also analysed to assess their contribution on the prices of the apartments, including the Central Business District (CBD), schools and universities, as well as the major city roads and the restricted zone that divides the country into two parts; the occupied by Turkish area and the Greek area. The values of the spatial attributes, or locational characteristics, were determined by employing GIS, considering an established model of multicriteria analysis. The price prediction model was analysed using the OLS method and calibrated based on the GWR method. The results of the statistic process indicate an accuracy of 81.34%, showing better performance than the mass valuation system applied by the Department of Land and Surveys in Cyprus with accuracy of 66.76%. This approach suggests that GIS systems are fundamentally important in mass valuation procedures in order to identify the spatial pattern of the attributes, provided that the database is comprised by a sufficient number of comparable

    2016-01-01

    In an attempt to improve the forecasting accuracy of crude oil price fluctuations, a new neural network architecture is established in this work which combines Multilayer perception and ERNN (Elman recurrent neural networks) with stochastic time effective function. ERNN is a time-varying predictive control system and is developed with the ability to keep memory of recent events in order to predict future output. The stochastic time effective function represents that the recent information has a stronger effect for the investors than the old information. With the established model the empirical research has a good performance in testing the predictive effects on four different time series indices. Compared to other models, the present model is possible to evaluate data from 1990s to today with extreme accuracy and speedy. The applied CID (complexity invariant distance) analysis and multiscale CID analysis, are provided as the new useful measures to evaluate a better predicting ability of the proposed model than other traditional models. - Highlights: • A new forecasting model is developed by a random Elman recurrent neural network. • The forecasting accuracy of crude oil price fluctuations is improved by the model. • The forecasting results of the proposed model are more accurate than compared models. • Two new distance analysis methods are applied to confirm the predicting results.

    There is growing interest in policies, programs and tariffs that encourage customer loads to provide demand response (DR) to help discipline wholesale electricity markets. Proposals at the retail level range from eliminating fixed rate tariffs as the default service for some or all customer groups to reinstituting utility-sponsored load management programs with market-based inducements to curtail. Alternative rate designs include time-of-use (TOU), day-ahead real-time pricing (RTP), critical peak pricing, and even pricing usage at real-time market balancing prices. Some Independent System Operators (ISOs) have implemented their own DR programs whereby load curtailment capabilities are treated as a system resource and are paid an equivalent value. The resulting load reductions from these tariffs and programs provide a variety of benefits, including limiting the ability of suppliers to increase spot and long-term market-clearing prices above competitive levels (Neenan et al., 2002; Boren stein, 2002; Ruff, 2002). Unfortunately, there is little information in the public domain to characterize and quantify how customers actually respond to these alternative dynamic pricing schemes. A few empirical studies of large customer RTP response have shown modest results for most customers, with a few very price-responsive customers providing most of the aggregate response (Herriges et al., 1993; Schwarz et al., 2002). However, these studies examined response to voluntary, two-part RTP programs implemented by utilities in states without retail competition.1 Furthermore, the researchers had limited information on customer characteristics so they were unable to identify the drivers to price response. In the absence of a compelling characterization of why customers join RTP programs and how they respond to prices, many initiatives to modernize retail electricity rates seem to be stymied.

    Climate change makes the water balance composition being unstable, both quality and quantity. As a company which responsible for water management, Regional Drinking Water Company (abbreviated as PDAM) is often unable to solve the problem. Welfare costs are indicators to evaluate the economic efficiency. This study aims to calculate the welfare cost of the people lost due to the price determination of PDAM Indonesia in region II with deadweight loss (DWL) approach, so it can provide information to pricing regulator, pricing decision makers and for coIDRorate management. DWL is a loss of economic efficiency that can occur when equilibrium for a good or a service is not achieved, caused by monopoly pricing of artificial scarcity, an externality, a tax or subsidy, or a binding price ceiling or price floor such as a minimum wage. Results showed that the pricing rules set by PDAM yielded different DWL, depending on margin set by the company DWL PDAM ranges between IDR 260,485.66/M3 to IDR 127,486,709.86/M3 which is actually shared to improve the welfare of customers, other communities, and PDAM itself. Data analysis used PDAM performance in 2015 that have not Good CoIDRorate Governance Management and Efficiency.

    Estimation of real properties depending on standards is difficult to apply in time and location. Regression analysis construct mathematical models which describe or explain relationships that may exist between variables. The problem of identifying price differences of properties to obtain a price index can be converted into a regression problem, and standard techniques of regression analysis can be used to estimate the index. Considering regression analysis for real estate valuation, which are presented in real marketing process with its current characteristics and quantifiers, the method will help us to find the effective factors or variables in the formation of the value. In this study, prices of housing for sale in Zeytinburnu, a district in Istanbul, are associated with its characteristics to find a price index, based on information received from a real estate web page. The associated variables used for the analysis are age, size in m2, number of floors having the house, floor number of the estate and number of rooms. The price of the estate represents the dependent variable, whereas the rest are independent variables. Prices from 60 real estates have been used for the analysis. Same price valued locations have been found and plotted on the map and equivalence curves have been drawn identifying the same valued zones as lines.

    The European Commission has proposed to reduce the greenhouse gas emissions to 80-95% below 1990 levels by 2050. Intermediately there is a binding legislation regarding the climate and energy targets for 2020. These targets, known as the ''20-20-20'' targets, set three key objectives for 2020: a 20% reduction in EU greenhouse gas emissions from 1990 levels, raising the share of EU energy consumption produced from renewable resources to 20% and a 20% improvement in the EU's energy efficiency. This policy is to be followed by the actions proposed in a policy framework for climate and energy in the period from 2020 to 2030: a new reduction target for domestic GHG emissions of 40% compared to 1990 for the year 2030, a target at European level for renewable energy of at least 27% for the year 2030 and a proposal for a 30% energy savings target for 2030. The 2020 targets for Italy translate into a 17% share of gross final energy consumption being delivered by Electricity from Renewable Energy Sources (RES-E). Various studies consider the integration of energy storage at the same time as RES-E as a solution to provide more flexibility in the energy system. Even though some studies model the electricity in higher detail, the case of Italy is rarely covered as an individual country. The goal of this paper is to evaluate the impact of adding storage in the Italian power system under different assumptions. The base case is the simplified assumption of a copper plate system where no transmission constraints are considered. This is then compared to the zonal dispatch which considers a simplified grid to underline the importance of locational signals for storage.

    Full Text Available Awareness of wheat farmers’ personal preferences towards environmental issues and weed types is important in pricing bioherbicides for sustainable weed management and could consequently be a fundamental guide to agricultural authorities and policy-makers. In the present study, a survey was carried out by using data collected from 180 wheat farmers of Korasan Razavi province during 2008, together with hedonic pricing method. The role of environmental qualitative factors and weed type on pricing environmental-friendly herbicides on the basis of “willingness to pay” was studied. Results from the estimation of hedonic pricing method indicated that reduction of water pollution, human health risk, farmers information about negative effects of chemical herbicides and the virtual variable of weed type had significant effects on pricing environmental friendly herbicides. Variables of soil pollution and weed perenniality had no significant effects on pricing herbicide applicable to sustainable agricultural systems. Based on the results of this study, possibilities of using bioherbicide or less pollutant herbicides and also the rate of farmers willingness to pay for alternatives in the region are important factors recommended for additional studies

    Commonly seen tender bid price information of the public works in Taiwan are the budget amount, floor price, awarding price and so on. The ratio of the awarding price to the floor price or budget price is the so-called bidding price ratio. This ratio is influenced by multifaceted factor interactions and is significant to decision making management in engineering projects. Low bidding price ratio may imply that the budget allocation by the tendering agency is inconsiderate or due to the improper market competition of low price bid rigging. High bidding price ratio in turn may indicate that the allocated budget is relatively low, bidder risks in increased contract execution uncertainty or even exclusive bidding scenario. Therefore, the correlation between the bidding price ratio and the aforementioned tender award information is the key issue of this study. This study gathered the tender information of the civil engineering projects in Taiwan within the past seven years. By performing statistical analysis and clustering the gathered data by bidding price ratio, this study investigated the influencing factors and regulations of bidding price ratio using data mining approach.

    Uncertainty is a crucial issue for producers who must make input decisions without knowing prices and without perfect knowledge of realized output. In this context, price expectations strongly determine the production choices and market prices that result from market-clearing conditions. This study analyzed the role that price expectations play in price dynamics, developing a theoretical model of trade in varieties following Armington (1969) and augmented with yield and price uncertainty to h...

  17. Oil price fluctuations and their impact on the macroeconomic variables of Kuwait: a case study using a VAR model

    Eltony, M. Nagy; Al-Awadi, Mohammad

    2001-01-01

    In this study, a vector autoregression model (VAR) and a vector error correction model (VECM) were estimated to examine the impact of oil price fluctuations on seven key macroeconomic variables for the Kuwaiti economy. Quarterly data for the period 1984-1998 were utilised. Theoretically and empirically speaking, VECM is superior to the VAR approach. Also, the results corresponding to the VECM model are closer to common sense. However, the estimated models indicate a high degree of interrelation between major macroeconomic variables. The empirical results highlight the causality running from the oil prices and oil revenues, to government development and current expenditure and then towards other variables. For the most part, the empirical evidence indicates that oil price shocks and hence oil revenues have a notable impact on government expenditure, both development and current. However, government development expenditure has been influenced relatively more. The results also point out the significant of the CPI in explaining a notable part of the variations of both types of government expenditure. On the other hand, the variations in value of imports are mostly accounted for by oil revenue fluctuations. On the other hand, the variations in value of imports are mostly accounted for by oil revenue fluctuations and then by the fluctuation in government development expenditures. Also, the results from the VECM approach indicate that a significant part of LM2 variance is explained by the variance in oil revenue. It reaches about 46 per cent in the 10th quarter, even more than its own variations. (Author)

    Full Text Available Agricultural land systems are the result of human interactions with the natural environment, and subjective evidence of socio-economic and environmental interactions has been demonstrated. Nevertheless, it is still difficult to analyze empirically the link between agricultural market and policy, as well as the environmental response due to changes in crop management by local stakeholders. In this study, we propose a cross investigation and analysis to bring the link between vegetation cover, policy, market and farmer’s behavior to light. Our methodology is a combination of a rational positive and analogical approach between the quantifiable and non-quantifiable agents on a temporal basis. The method is applied to a dominant mono-crop agricultural watershed in Southern Italy that has been dedicated to durum wheat cultivation. In this region, we studied the relationship between the Common Agricultural Policy (CAP, durum wheat market price, vegetation cover and land allocation. As a first step, we conducted a separate analysis for each factor, exploiting Moderate Resolution Imaging Spectroradiometer (MODIS satellite observed Leaf Area Index (LAI to analyze the land vegetation space–time distribution over the period 2000–2014 and three Land Satellite (Landsat validated images as check-points for the agricultural pattern and CAP’s reforms. We used the Farm Accountancy Data Network (FADN and Eurostat data to investigate the on-farm accountancy and the durum wheat market price changes, respectively. Based on the study period, we developed a storyline of the major relevant CAP’s policy changes. In a second step, we conducted a comparative analysis where the CAP’s reforms were used as interpretational support, the land allocation and the on-farm accountability for CAP’s implementation, the price of durum wheat and the LAI for analytical comparison. We found interesting insights regarding the non-agronomic driving forces of LAI dynamics. The

    Full Text Available The dynamic of 3-parties conflict of interests (investor, local people and government in having actual income from the nature tourism park business in Indonesia became worse since a “very  progressive” Government Regulation on Forestry Related Services Tariff (so called PP 12/2014 was issued.  On one hand, everybody agrees to improve the 17 years old tariff regulation of PP 59/1998. On the other hand, the “unclear reason” of the new tariffs in PP 12/2014 has shocked many parties and created many difficulties while implemented. This paper studies visitors’ expenditures and their willingness to pay (WTP for every recreation services scenario by using contingent valuation method (CVM survey with open-ended eliciting questionnaire instrument. Regarding the characteristic of Gunung Pancar Forest Tourism Park (GPFTP the method was used to justify a reasonable and eligible ticket pricing strategy at the GPFTP as a quasi-public recreation park. The survey has also specifically addressed the reasonable ticket-price that aligns with the financial assumption of investor's business plan and local people's economic activities. Results of the survey  show that the continuum of visitors’ WTP is ranging from 3.4 times (as the response to scenario-1 up to 12.7 times (as the response to scenario-5 of the recent ticket price. The WTP of scenario-2, 3 and 4 are ranging from 4.7, 6.2 and 7.5 times, respectively. Furthermore, the results of Tobit Regression Analysis show that seven important variables are positively correlated, while six variables are negatively correlated with the WTP.

  2. Risk assessment of new pricing strategies in the district heating market. A case study at Sundsvall Energi AB

    2010-01-01

    The price structure of district heating has been no major scientific issue for the last decades in energy-related research. However, today trends in district heating pricing tend to move towards a more customer-oriented approach with predetermined prices under a longer periods, leading to a more complex price structure. If a district heating supplier offers district heating with predetermined prices in order to compete with similar electricity offers, the financial risk of the new price structure is significantly higher than the risk of an ordinary variable cost offer based on short-run marginal cost. In contrary to an electricity seller, the district heating company cannot transfer all of the risk of predetermined prices to the financial market, instead the company is thrown upon its own ability to handle the risk by, e.g., hedging its own energy purchase. However, all uncertainties cannot be coped with in this manner. Thus, there is a need for a methodology that can be used to estimate the financial risk of different price structures and to value different opportunities to reduce the risk. In this article, we propose a methodology, implemented in prototype software, to evaluate the risk associated with new price structures in district heating. (author)

  3. Lessons from game theory about healthcare system price inflation: evidence from a community-level case study.

    Science.gov (United States)

    Agee, Mark D; Gates, Zane

    2013-02-01

    Game theory is useful for identifying conditions under which individual stakeholders in a collective action problem interact in ways that are more cooperative and in the best interest of the collective. The literature applying game theory to healthcare markets predicts that when providers set prices for services autonomously and in a noncooperative fashion, the market will be susceptible to ongoing price inflation. We compare the traditional fee-for-service pricing framework with an alternative framework involving modified doctor, hospital and insurer pricing and incentive strategies. While the fee-for-service framework generally allows providers to set prices autonomously, the alternative framework constrains providers to interact more cooperatively. We use community-level provider and insurer data to compare provider and insurer costs and patient wellness under the traditional and modified pricing frameworks. The alternative pricing framework assumes (i) providers agree to manage all outpatient claims; (ii) the insurer agrees to manage all inpatient clams; and (iii) insurance premiums are tied to patients' healthy behaviours. Consistent with game theory predictions, the more cooperative alternative pricing framework benefits all parties by producing substantially lower administrative costs along with higher profit margins for the providers and the insurer. With insurance premiums tied to consumers' risk-reducing behaviours, the cost of insurance likewise decreases for both the consumer and the insurer.

  4. A case study of ex ante, value-based price and reimbursement decision-making: TLV and rimonabant in Sweden.

    2010-04-01

    Value-based pricing (VBP) is a method of setting prices for products based on perceived benefits to the consumer. When information is symmetric and freely available and agency is perfect, VBP is efficient and desirable. Because of substantial information asymmetries, medical insurance distortions, and the prescribing monopoly of physicians, VBP is rare for prescription drugs, though a number of countries have recently moved in this direction. Because the potential benefits can be sizable, it is high time for a review of actual VBP-based decision-making in practice. Sweden, with its pharmaceutical benefits board (TLV), was an early adopter of VBP decision-making. We illustrate actual decision-making, thus, using the case of Acomplia for the treatment of obesity in Sweden, with and without the presence of co-morbid conditions. This example has a number of features that will be useful in illustrating the strengths and weaknesses of VBP in actual practice, including multiple indications, a need for not just one but two economic simulation models, considerable sub-group analysis, and requirements for additional evidence development. TLV concluded, in 2006, that Acomplia was cost-effective for patients with a body mass index (BMI) exceeding 35 kg/m2 and patients with a BMI exceeding 28 kg/m2 and either dyslipidemia or type 2 diabetes. Because of uncertainty in some of the underlying assumptions, reimbursement was granted only until 31 December 2008, at which time the manufacturer would be required to submit additional documentation of the long-term effects and cost-effectiveness in order to obtain continued reimbursement. Deciding on reimbursement coverage for pharmaceutical products is difficult. Ex ante VBP assessment is a form of risk sharing, which has been used by TLV to speed up reimbursement and dispersion of effective new drugs despite uncertainty in their true cost-effectiveness. Manufacturers are often asked in return to generate additional health economic

    The objective of this article is to investigate whether the Chinese government's pricing policies have reduced pharmaceutical expenses. The purchasing records for systemic antibacterial drugs of 12 hospitals in Beijing from 1996 to 2005 were analyzed by separating the expenditure growth into three components: the price change, the volume change, and the structure change. Our results reveal that the structure change is the dominant determinant of drug expenditure growth. Despite lowered prices, the antibacterial drug expenditure was raised because more expensive drugs in the same therapeutic category were prescribed. It is insufficient to rely only on pricing policies to reduce drug expenses, given that physicians could circumvent the policy by prescribing more expensive drugs. In addition, physician behaviors need to be regulated to eliminate unnecessary overprescribing.

  6. Development of a Model for a Cordon Pricing Scheme Considering Environmental Equity: A Case Study of Tehran

    2016-02-01

    Full Text Available Congestion pricing strategy has been recognized as an effective countermeasure in the practical field of urban traffic congestion mitigation. Despite the positive effects of congestion pricing, its implementation has faced problems. This paper investigates the issue of environmental equity in cordon pricing and a park-and-ride scheme. Although pollution decreases inside the cordon by implementation of cordon pricing, air pollutants emission may increase in some links and in the whole network. Therefore, an increase in air emissions in the network means more emission outside the cordon. In fact, due to the implementation of this policy, air pollutants emission may transfer from inside to outside the cordon, creating a type of environmental inequity. To reduce this inequity, a bi-level optimization model with an equity constraint is developed. The proposed solution algorithm based on the second version of the strength Pareto evolutionary algorithm (SPEA2 is applied to the city network in Tehran. The results revealed that it seems reasonable to consider environmental equity as an objective function in cordon pricing. In addition, we can create a sustainable situation for the transportation system by improving environmental inequity with a relatively low reduction in social welfare. Moreover, there are environmental inequity impacts in real networks, which should be considered in the cordon pricing scheme.

    2014-07-01

    Full Text Available In West African Sahel cities, livestock husbandry such as smallholder dairy production and livestock (cattle, sheep and goat fattening has become popular among livestock owners to meet food needs for the household, and for income generation. The increasing importance of urban and suburban agriculture, particularly livestock husbandry in the region, has led to a rapid increase in livestock populations in most of the cities. As a result of this increase and the associated growth in the demand for feeds, feed markets have sprung up in many cities and towns of West Africa’s Sahel. A survey of livestock feed markets was conducted in five markets in Bamako, Mali. Prices of livestock feeds were monitored monthly from January to December 2010. In addition, feed samples were collected from the markets for laboratory analysis to determine their nutritional quality. Results showed that the prices of cowpea hay and groundnut haulm were consistently higher than those of other feeds throughout the year. The price of cowpea hay ranged from 367 FCFA/kg dry matter (DM (1 USD ≈ 500 FCFA in October, i.e. immediately after harvest, to 667 FCFA/kg DM in August, i.e. in the wet season. Results also showed that there was no relationship between price and quality for all feed types. However, prices and quality of feeds differed significantly across seasons suggesting that the season was a major determinant for the price of livestock feeds in suburban areas of West Africa’s Sahel.

    Full Text Available Aim/purpose - The paper was aimed to find out if abnormal returns occur before and after changes in the names of companies listed on the Warsaw Stock Exchange. Design/methodology/approach - Due to the fact that this was an early stage of the research, an appropriate methodology was used in the research which took into account indexes of relative force of quotations of some selected companies in relation to the wide Warsaw Stock Exchange WIG index. Findings - The research findings proved the existence of positive abnormal returns before the name changes and negative trends after the name changes in companies in the long term. Comparing the average volume of share trading before and after the name changes in companies, no positive effect was noticed in this scope. Research implications/limitations - The clear and unambiguous results appear to be significant for investors while taking investment decisions. Therefore, the conclusions from the findings of the pilot research need to be confirmed and verified in further studies on the problem, with the use of a more advanced methods. Originality/value/contribution - The paper represents one of the few empirical studies on the impact of the name changes of listed companies on the share prices in relation to the emerging markets, and the first ones concerning the Polish share market. The findings of the study may give grounds to discuss and identify practical causes of market behaviors as a result of changes in companies' names.(original abstract

    Directory of Open Access Journals (Sweden)

    Ijeoma C. Nwoko

    2016-12-01

    Full Text Available This study examines the long and short run relationships between oil price and food price volatility as well as the causal link between them. The study used annual food price volatility index from FAO from 2000 to 2013 and crude oil price from U.S. Energy Information and Administration (EIA from 2000 to 2013. The Johansen and Jesulius co-integration test revealed that there is a long run relationship between oil price and domestic food price volatility. The vector error correction model indicated a positive and significant short run relationship between oil price and food price volatility. The Granger causality test revealed a unidirectional causality with causality running from oil price to food price volatility but not vice versa. It is recommended that policies and interventions that will help reduce uncertainty about food prices such as improved market information, trade policies and investment in research and development among others should be encouraged. Also to reduce the effect of oil price shock, it is recommended that government should subsidise pump price of refined oil, seek alternative sources of energy and there should be less dependence on oil for fertilizer production.

    2001-12-01

    Reasonable pricing of water can induce optimal water use by the public by relaying the considerable costs of water provision and plays an important role of providing a basic scheme for the reasonable management of water. This study provides a reasonable pricing scheme of water that reflects the economic and social values of water as a resource by investigating reasonable bulk-water pricing and retail-water pricing. For bulk pricing, the study discuss the range of costs to be covered, design of efficient pricing structures(differentiated by source quality, loss ratios and time year), and sharing efficient costs between beneficiaries (customer groups and regions). The study also addresses the adjustment of present charging schemes for bulk water such as charges for bulk water from dam, abstraction charges, and river charges etc. Factoring in demand and available resource characteristics, the differentiated pricing mechanism is also investigated. The study proposes a differentiated pricing mechanism based on season, where the pricing structure reflects the cost structure related to fluctuated demand. In addition, implementation methods and effects of introducing seasonal pricing scheme are discussed. Another seasonal pricing mechanism, the seasonally differentiated pricing scheme in bulk pricing reflects a cost structure related to resource availability, is also investigated. Increasing block rate as a reasonable pricing scheme for water conservation, and priority pricing as a tool socially desirable water allocation in the case water shortage are designed. for practical implementation of pricing scheme, several issues are discussed: identification and calculation of costs that should be covered and the structure of costs as a basis of differentiated pricing scheme, issue of forecasting, and practical that could be happen in the implementation of increasing block rate and seasonal pricing schemes, etc. Institutional systems that implement the proposed pricing schemes

    Mass media influence public acceptability, and hence feasibility, of public health interventions. This study investigates newsprint constructions of the alcohol problem and minimum unit pricing (MUP). Quantitative content analysis of 901 articles about MUP published in 10 UK and Scottish newspapers between 2005 and 2012. MUP was a high-profile issue, particularly in Scottish publications. Reporting increased steadily between 2008 and 2012, matching the growing status of the debate. The alcohol problem was widely acknowledged, often associated with youths, and portrayed as driven by cheap alcohol, supermarkets and drinking culture. Over-consumption was presented as a threat to health and social order. Appraisals of MUP were neutral, with supportiveness increasing slightly over time. Arguments focused on health impacts more frequently than more emotive perspectives or business interests. Health charities and the NHS were cited slightly more frequently than alcohol industry representatives. Emphases on efficacy, evidence and experts are positive signs for evidence-based policymaking. The high profile of MUP, along with growing support within articles, could reflect growing appetite for action on the alcohol problem. Representations of the problem as structurally driven might engender support for legislative solutions, although cultural explanations remain common. © The Author 2014.

    From the perspective of risk, nuclear-power-related facilities (NPRFs) are often regarded as locally undesirable land use. However, construction of NPRFs contributes to social infrastructural improvement and job creation in the host communities. This raises a question: How large are these positive and negative effects? To approach this question from an economic viewpoint, we estimated the hedonic land price function for the Mutsu-Ogawara region of Japan from 1976 to 2004 and analyzed year-by-year fluctuations in land prices around the NPRFs located there. Land prices increased gradually in the neighborhood of the nuclear fuel cycle facilities (NFCFs) in Rokkasho Village, except for some falling (i) from 1982 to 1983 (the first official announcement of the project of construction came in 1983), (ii) from 1987 to 1988 (in 1988, the construction began and opposition movements against the project reached their peak), and (iii) from 1998 to 1999 (the pilot carry-in of spent fuels into the reprocessing plant began in 1998). Land prices around the Higashidori Nuclear Power Plant decreased during the period 1981-1982, when the Tohoku Electric Power Corp. and Tokyo Electric Power Corp. announced their joint construction plan. On the other hand, we obtained some results, even though not significant, indicating that land prices around Ohminato and Sekinehama harbors changed with the arrival and departure of the nuclear ship Mutsu, which suffered a radiation leak in 1974. © 2011 Society for Risk Analysis.

    Ackchai Sirikijpanichkul

    2015-01-01

    Full Text Available Traffic congestion is a chronic problem of Bangkok. Similar to other metropolises, the city perpetually seeks for alternatives to road travel. Mass rapid transit seems to be the only way out that is expected to mitigate traffic congestion in the city. However, without common fare system, travelers need to pay an initial entrance fee every time they enter each transit system. This excess cost tapers the demand and affects the efficient use of the system. This research investigates the influence of fare price on transit use which is measured by price elasticity of demand and proposes the optimum fare price if the common fare is used. The analysis is based on the findings from the stated preference survey techniques. Finally, the conclusion on fare level that encourage more patronage, maintain service quality and operator revenue is addressed.

    Demand response (DR) has been broadly recognized to be an integral component of well-functioning electricity markets, although currently underdeveloped in most regions. Among the various initiatives undertaken to remedy this deficiency, public utility commissions (PUC) and utilities have considered implementing dynamic pricing tariffs, such as real-time pricing (RTP), and other retail pricing mechanisms that communicate an incentive for electricity consumers to reduce their usage during periods of high generation supply costs or system reliability contingencies. Efforts to introduce DR into retail electricity markets confront a range of basic policy issues. First, a fundamental issue in any market context is how to organize the process for developing and implementing DR mechanisms in a manner that facilitates productive participation by affected stakeholder groups. Second, in regions with retail choice, policymakers and stakeholders face the threshold question of whether it is appropriate for utilities to offer a range of dynamic pricing tariffs and DR programs, or just ''plain vanilla'' default service. Although positions on this issue may be based primarily on principle, two empirical questions may have some bearing--namely, what level of price response can be expected through the competitive retail market, and whether establishing RTP as the default service is likely to result in an appreciable level of DR? Third, if utilities are to have a direct role in developing DR, what types of retail pricing mechanisms are most appropriate and likely to have the desired policy impact (e.g., RTP, other dynamic pricing options, DR programs, or some combination)? Given a decision to develop utility RTP tariffs, three basic implementation issues require attention. First, should it be a default or optional tariff, and for which customer classes? Second, what types of tariff design is most appropriate, given prevailing policy objectives, wholesale market

    Novel policy interventions may lack evaluation-based evidence. Considerations to introduce minimum unit pricing (MUP) of alcohol in the UK were informed by econometric modelling (the 'Sheffield model'). We aim to investigate policy stakeholders' views of the utility of modelling studies for public health policy. In-depth qualitative interviews with 36 individuals involved in MUP policy debates (purposively sampled to include civil servants, politicians, academics, advocates and industry-related actors) were conducted and thematically analysed. Interviewees felt familiar with modelling studies and often displayed detailed understandings of the Sheffield model. Despite this, many were uneasy about the extent to which the Sheffield model could be relied on for informing policymaking and preferred traditional evaluations. A tension was identified between this preference for post hoc evaluations and a desire for evidence derived from local data, with modelling seen to offer high external validity. MUP critics expressed concern that the Sheffield model did not adequately capture the 'real life' world of the alcohol market, which was conceptualized as a complex and, to some extent, inherently unpredictable system. Communication of modelling results was considered intrinsically difficult but presenting an appropriate picture of the uncertainties inherent in modelling was viewed as desirable. There was general enthusiasm for increased use of econometric modelling to inform future policymaking but an appreciation that such evidence should only form one input into the process. Modelling studies are valued by policymakers as they provide contextually relevant evidence for novel policies, but tensions exist with views of traditional evaluation-based evidence. © The Author 2013.

    not contain either an infinite time horizon or conditions where all dynamic enterprises stop at the end of the horizon. Consequently, terminal conditions are important. Terminal conditions reflect the value of in-process inventory beyond the final period explicitly modeled and should either value or require a minimum level of inventory. When used, terminal values should reflect the net present value of the future income stream earned by ending the time horizon with a unit of the in-process inventory. Such conditions can insure that model activity will be reasonable up until the final year. The error created by ignoring terminal conditions can be illustrated through example. Data required in the study for the crop year of 2011-2012, were collected by farmers in Orzoiyeh using questionnaires along with data of the Regional Water and Agriculture Organization of Kerman were collected. Results and Discussion: results showed, that although the policy guaranteed purchase of wheat increased in agricultural gross profit ,it is not compatible with water resources management. Therefore, policymakers should enact policies to support the production, they considered the side effects on water resources in addition to encourage more production was also important to protect water resources. In order to reduce the exploitation of water resources, in line with the policy of supporting the production of water-price policies gradually, developing new technologies and water saving, promoting drought resistant varieties and the optimal irrigation strategies can be implemented. Conclusion: Policy makers should enact policies that support the production, they considered the side effects on water resources in addition to encouraging more production was also important to protect water resources. In order to reduce the exploitation of water resources, in line with the policy of supporting the production of water-price policies gradually, developing new technologies and water saving, promotion

    Full Text Available The transfer price scope is becoming a very important issue for all companies that comprise from different departments or have a network of branches. These companies are obliged to present the way of price determination for transactions that they have with their branches or other relevant members of their network. The establishment of the multinational companies that develop their activities in various countries is being increased. It has increased the need to supervise their transactions and approval of laws and administrative orders that do not leave space for misuses. The paper is focused in the response to the question if the Comparable Uncontrolled Price Method is the best method to be used in all cases. It is presented through a concrete example that shows how the price of a product determined through the Comparable Uncontrolled Price Method or market price has an impact to the profit of the mother company and other subsidiaries.

    Full Text Available Human brucellosis has reemerged as a serious public health threat to the Bedouin population of southern Israel in recent years. Little is known about its economic implications derived from elevated healthcare utilization (HCU. Our objective was to estimate the HCU costs associated with human brucellosis from the insurer perspective. A case-control retrospective study was conducted among Clalit Health Services (CHS enrollees.

    Human brucellosis has reemerged as a serious public health threat to the Bedouin population of southern Israel in recent years. Little is known about its economic implications derived from elevated healthcare utilization (HCU). Our objective was to estimate the HCU costs associated with human brucellosis from the insurer perspective. A case-control retrospective study was conducted among Clalit Health Services (CHS) enrollees. Brucellosis cases were defined as individuals that were diagnosed with brucellosis at the Clinical Microbiology Laboratory of Soroka University Medical Center in the 2010-2012 period (n = 470). Control subjects were randomly selected and matched 1:3 by age, sex, clinic, and primary physician (n = 1,410).

    This study analyzes the effects of oil price fluctuations on regional macroeconomic variables with a structural VAR model. We classified fifteen metropolitan cities and provinces of Korea into four major regions (Capital, Central, Honam, and Gyeongsang) and examined the effects of oil price fluctuations on the economy of these regions. The results in the short- and long-term lag structures show a negative response to industrial production and price. The Capital region is less affected by oil price fluctuations than the other three provincial regions. We concluded that the government should focus on creating an industrial environment to accumulate production factors and technologies in oil price-sensitive regions. - Highlights: ► We examined the effects of oil price shocks on four major economic areas of South Korea. ► We used structural VAR analysis. ► We showed that the production structure of a region influences the impact of oil price shocks. ► We inference that the government should focus on creating an industrial environment.

    Scotland is the first country in the world to pass legislation introducing a minimum unit price (MUP) for alcohol in an attempt to reduce consumption and associated harms by increasing the price of the cheapest alcohol. We investigated the competing ways in which policy stakeholders presented the debate. We then established whether a change in framing helped explain the policy's emergence. We conducted a detailed policy case study through analysis of evidence submitted to the Scottish parliament, and in-depth, one-to-one interviews (n = 36) with politicians, civil servants, advocates, researchers, and industry representatives. Public- and voluntary-sector stakeholders tended to support MUP, while industry representatives were more divided. Two markedly different ways of presenting alcohol as a policy problem were evident. Critics of MUP (all of whom were related to industry) emphasized social disorder issues, particularly among young people, and hence argued for targeted approaches. In contrast, advocates for MUP (with the exception of those in industry) focused on alcohol as a health issue arising from overconsumption at a population level, thus suggesting that population-based interventions were necessary. Industry stakeholders favoring MUP adopted a hybrid framing, maintaining several aspects of the critical framing. Our interview data showed that public health advocates worked hard to redefine the policy issue by deliberately presenting a consistent alternative framing. Framing alcohol policy as a broad, multisectoral, public health issue that requires a whole-population approach has been crucial to enabling policymakers to seriously consider MUP, and public health advocates intentionally presented alcohol policy in this way. This reframing helped prioritize public health considerations in the policy debate and represents a deliberate strategy for consideration by those advocating for policy change around the world and in other public health areas. © 2014

    Price volatility analysis has been reported in the literature for most competitive electricity markets around the world. However, no studies have been published yet that quantify price volatility in the Ontario electricity market, which is the focus of the present paper. In this paper, a comparative volatility analysis is conducted for the Ontario market and its neighboring electricity markets. Volatility indices are developed based on historical volatility and price velocity concepts, previously applied to other electricity market prices, and employed in the present work. The analysis is carried out in two scenarios: in the first scenario, the volatility indices are determined for the entire price time series. In the second scenario, the price time series are broken up into 24 time series for each of the 24 h and volatility indices are calculated for each specific hour separately. The volatility indices are also applied to the locational marginal prices of several pricing points in the New England, New York, and PJM electricity markets. The outcomes reveal that price volatility is significantly higher in Ontario than the three studied neighboring electricity markets. Furthermore, comparison of the results of this study with similar findings previously published for 15 other electricity markets demonstrates that the Ontario electricity market is one of the most volatile electricity markets world-wide. This high volatility is argued to be associated with the fact that Ontario is a single-settlement, real-time market

    Full Text Available This study analyses the impacts of environmental amenities associated with agricultural and silvicultural land use on the price of rural tourism accommodation in Asturias (Spain. A hedonic price model that relates the price of rural accommodation to environmental amenities as well as equipment, services offered, and the locational characteristics of the accommodation is estimated. The rural accommodations in the study are the self-catering cottages, the intrinsic features of which promote the development of rural tourism sustainability. Geographic information systems (GIS data are used to measure the location and the proximity to amenities of these self-catering cottages. The main results indicate that agricultural land use has an important impact on the price of accommodation in self-catering cottages. Specifically, a high percentage of grassland in the municipality where the self-catering cottage is sited has a positive effect on rental prices, while a high percentage of arable crops has the opposite effect. The analysis is interesting for decision-making in the context of environmental policies, land use conflict resolution, and rural tourism sustainability.

    It is believed that laboratory tariffs in Iran don't reflect the real costs. This might expose private laboratories at financial hardship. Activity Based Costing is widely used as a cost measurement instrument to more closely approximate the true cost of operations. This study aimed to determine the real price of different clinical tests of a selected private clinical laboratory. This study was a cross sectional study carried out in 2015. The study setting was the private laboratories in the city of Kerman, Iran. Of 629 tests in the tariff book of the laboratory (relative value), 188 tests were conducted in the laboratory that used Activity Based Costing (ABC) methodology to estimate cost-price. Analyzing and cost-price estimating of laboratory services were performed by MY ABCM software Version 5.0. In 2015, the total costs were $641,645. Direct and indirect costs were 78.3% and 21.7% respectively. Laboratory consumable costs by 37% and personnel costs by 36.3% had the largest share of the costing. Also, group of hormone tests cost the most $147,741 (23.03%), and other tests group cost the least $3,611 (0.56%). Also after calculating the cost of laboratory services, a comparison was made between the calculated price and the private sector's tariffs in 2015. This study showed that there was a difference between costs and tariffs in the private laboratory. One way to overcome this problem is to increase the number of laboratory tests with regard to capacity of the laboratories.

    The price terms in wheeling contracts very substantially, reflecting the differing conditions affecting the parties contracting for the service. These terms differ in the manner in which rates are calculated, the formulas used, and the philosophy underlying the accord. For example, and EEI study found that firm wheeling rates ranged from 20 cents to $1.612 per kilowatt per month. Nonfirm rates ranged from .15 mills to 5.25 mills per kilowatt-hour. The focus in this chapter is on cost-based rates, reflecting the fact that the vast majority of existing contracts are based on rate designs reflecting embedded costs. This situation may change in the future, but, for now, this fact can't be ignored

    China's 2009 national essential medicine system (NEMS) was designed to reduce prices through a zero-markup policy and a centralized bidding system. To analyze NEMS's short-term impact on drug prices, we estimated the retail and wholesale prices before and after the reform at health institutions in rural Jiangxi Province. We undertook two cross-sectional surveys of prices of 39 medicines in November 2008 and May 2010, calculated inflation adjusted prices, and used the Wilcoxon signed-rank and rank-sum tests to examine price changes at different health institutions. Retail prices at pilot (P health centers decreased significantly, whereas the declines at retail pharmacies (P = 0.57) and village clinics (P = 0.29) were insignificant. The decline at pilot township health centers was the largest, compared with other kinds of health institutions (P health institutions, the centralized bidding system was insufficient to lower wholesale prices. A drug price management system should be constructed to control medicine prices and a long-term price information system is needed to monitor price changes.

    The right pricing of products is one of the most important issues concerning the development of companies’ financial performance. Prices should be low enough to attract customers and at the same time high enough to cover all the emerged costs and expected profits. This research illustrates how self-organizing maps (SOM) can be used for pricing purposes. We show how changes in a company’s pricing policies would affect the company’s pricing position. The study illustrates clearly that companies...

    While the distinct behaviors of for-profit and non-profit providers in the healthcare market have been compared in the economic literature, their choices regarding market entry and exit have only recently been debated. Since 2000, when public Long-Term Care Insurance was introduced in Japan, for-profit providers have been able to provide formal long-term homecare services. The aim of this study is to determine which factors have affected market entry of for-profit providers under price regulation and in competition with existing non-profit providers. We used nation-wide panel data from 2002 to 2010, aggregated at the level of local public insurers (n = 1557), a basic area unit of service provision. The number of for-profit providers per elderly population in the area unit was regressed against factors related to local demand and service costs using first-difference linear regression, a fixed effects model, and Tobit regression for robustness checking. Results showed that demand (the number of eligible care recipients) and cost factors (population density and minimum wage) significantly influenced for-profit providers' choice of market entry. These findings indicate that for-profit providers will strategically choose a local market for maximizing profit. We believe that price regulation should be redesigned to incorporate quality of care and market conditions, regardless of the profit status of the providers, to ensure equal access to efficient delivery of long-term care across all regions.

  14. Effects of an oil price rise on inflation, output, and the exchange rate in the case of subsidization policy

    Since the Organization of Petroleum Exporting Countries raised the price of oil by 400% in 1974, the theory of supply inflation has received a great deal of attention. This study analyses the short and long run effects of an oil price rise on output, inflation, and the exchange rate. The study also analyses dynamic adjustments to the oil price rise in cases where oil-price subsidies are provided and where no subsidies are provided. In the no-subsidy case it is shown that the oil price rise can be inflationary or deflationary. The implications of the policy of subsidizing the price of oil is highlighted by taking account of a government budget constraint which in turn leads to the possibility of monetization as a source of financing the deficit, and thereby to higher output relative to the no subsidy case. As to the price level, the possibility is illustrated that subsidization can actually be more inflationary. The important element giving rise to the above possibility is the subsidy induced increase in the money supply. Exchange-rate flexibility is shown not to insulate the domestic price level against an oil price rise. In the long run the rate of inflation and exchange-rate variations are determined by the rate of growth of the money supply. The dynamic adjustment path of price and output is shown to be determined by the rate of adjustment of inflationary expectations.

    delay, based on hours spent in traffic in a year, grew by 22% as the national average of hours spent in delay grew from 36 hours to 44 hours. Peak delay per traveler grew one-third in medium-size urban areas over the 10 year period. The traffic engineering community has developed an arsenal of integrated tools to mitigate the impacts of congestion on freeway throughput and performance, including pricing of capacity to manage demand for travel. Congestion pricing is a strategy which dynamically matches demand with available capacity. A congestion price is a user fee equal to the added cost imposed on other travelers as a result of the last traveler's entry into the highway network. The concept is based on the idea that motorists should pay for the additional congestion they create when entering a congested road. The concept calls for fees to vary according to the level of congestion with the price mechanism applied to make travelers more fully aware of the congestion externality they impose on other travelers and the system itself. The operational rationales for the institution of pricing strategies are to improve the efficiency of operations in a corridor and/or to better manage congestion. To this end, the objectives of this project were to: (1) Better understand and quantify the impacts of congestion pricing strategies on traffic operations through the study of actual projects, and (2) Better understand and quantify the impacts of congestion pricing strategies on traffic operations through the use of modeling and other analytical methods. Specifically, the project was to identify credible analytical procedures that FHWA can use to quantify the impacts of various congestion pricing strategies on traffic flow (throughput) and congestion.

    Full Text Available During the last decades, life expectancy has risen significantly in the most developed countries all over the world. Greece is a case in point; consequently, higher governmental financial responsibilities occur as well as serious concerns are raised owing to population ageing. To address this issue, an efficient forecasting method is required. Therefore, the most important stochastic models were comparatively applied to Greek data for the first time. An analysis of their fitting behaviour by gender was conducted and the corresponding forecasting results were evaluated. In particular, we incorporated the Greek population data into seven stochastic mortality models under a common age-period-cohort framework. The fitting performance of each model was thoroughly evaluated based on information criteria values as well as the likelihood ratio test and their robustness to period changes was investigated. In addition, parameter risk in forecasts was assessed by employing bootstrapping techniques. For completeness, projection results for both genders were also illustrated in pricing insurance-related products.

  1. Using an innovative price model to leverage the business model – The case of price model innovation in the largest Swedish taxi company

    Directory of Open Access Journals (Sweden)

    Carl-Johan Petri

    2014-08-01

    Full Text Available Purpose: The purpose of the paper is to describe how the biggest Swedish taxi company (Taxi Kurir developed an innovative price model to leverage the business model. Design/methodology/approach : The empirical data in the article describe Taxi Kurir’s development of a new price model. Data about the Swedish taxi market and about Taxi Kurir has been compiled though interviews and document studies. Detailed information about the background, development and implementation of Taxi Kurir’s new price model has been captured through interviews with representatives from Taxi Kurir. Findings : Based on both the empirical example, and other investigations, we have found that a company can create substantial changes in their price model, by just changing some of its basic characteristics. A well designed price model can contribute to leveraging the intentions of the business model. Practical implications : Most academic and practical texts about business models consider pricing to be an important component. However, they typically do not refer to the specifics of the price- or revenue models. According to the literature review in this paper, and the empirical findings, the configuration of a company’s price model should be aligned with its business model. This will contribute to leveraging the business model. Originality/value: The Swedish taxi market is one of the most deregulated in the world. Differently from most other countries, any individual or company can start and operate a taxi business. This case offers a unique description on how the biggest company in the market responded to the competition by introducing a fundamentally new price model, by making a small change in one of the dimensions in their existing price model.

  2. Water Pricing and Implementation Strategies for the Sustainability of an Irrigation System: A Case Study within the Command Area of the Rakh Branch Canal

    2018-04-01

    Full Text Available The command area of the Rakh branch canal grows wheat, sugarcane, and rice crops in abundance. The canal water, which is trivial for irrigating these crops, is conveyed to the farms through the network of canals and distributaries. For the maintenance of this vast infrastructure; the end users are charged on a seasonal basis. The present water charges are severely criticized for not being adequate to properly manage the entire infrastructure. We use the residual value to determine the value of the irrigation water and then based on the quantity of irrigation water supplied to farm land coupled with the infrastructure maintenance cost, full cost recovery figures are executed for the study area, and policy recommendations are made for the implementation of the full cost recovery system. The approach is unique in the sense that the pricings are based on the actual quantity of water conveyed to the field for irrigating crops. The results of our analysis showed that the canal water is severely under charged in the culturable command area of selected distributaries, thus negating the plan of having a self-sustainable irrigation system.

    Full Text Available Food prices traditionally have an impact on inflation around the world. Movements in these prices are coming more from the supply side, then from the demand side. If treated as a supply shock, monetary policy should not react. However, food prices are part of headline inflation that is an official target for most central banks. Serbia conducts Inflation targeting and faces serious challenges with food price volatility. Food price volatility in Serbia hampers inflation forecasting, and may have a negative influence on inflationary expectations and public confidence in (i.e. credibility of the Central bank, all of crucial importance for success of Inflation targeting. There are several important possible improvements that may decrease volatility of food prices but also limit negative impact of food price volatility on Consumer Price Index (CPI as a measure of inflation. These improvements are very important for success of Inflation targeting in Serbia.

  5. When should green technology support policies supplement the carbon price? The case of the electricity sector

    Lecuyer, Oskar

    2013-01-01

    This thesis contributes to the literature on optimal policy choice. It studies the use of policy combinations to mitigate greenhouse gases emissions from electricity production. One finding applies to cases where uncertainty is such that the risk of a nil carbon price cannot be excluded. A cap on emissions alone may then not trigger enough abatements, justifying the addition of e.g. a renewable subsidy. When considering a transition toward a carbon free electricity sector, capital accumulation causes complex dynamic effects to happen. We find that decisions taken by comparing the leveled costs of abatement technologies, even including carbon costs, would favor intermediate technologies (e.g. gas plants) to the detriment of more-expensive but lower-carbon technologies (renewable power), leading to a suboptimal investment schedule. This thesis also studies the effects of marginal policy changes in a mix comprising the main French instruments. We find that surprisingly, adding a tariff for renewables financed by a tax on electricity consumption to a cap on emissions and a subsidy for energy efficiency will reduce the consumer electricity price when the non-renewable production is fixed and does not depend on the carbon price. The assessment of the French climate policies in the electricity sector shows that overlapping policies for mitigation may be justified by multiple carbon price failures, even if the ideal long-term policy mix depends on the carbon price trajectory.

  6. Price versus Non-price Incentives for Participation in Quality Labeling: The Case of the German Fruit Juice Industry

    Directory of Open Access Journals (Sweden)

    Simon Bleich

    2013-03-01

    Full Text Available Quality assurance and labeling play an important and increasing role in firms’ marketing strategies. In almost all cases, a price incentive has been stressed as the major incentive for firms to participate in such schemes. We argue here that important non-price incentives for participation in quality labeling may exist, too. In German retailing, it can be observed that discount retailers are listing more and more foods with quality labels. Processors may then participate in voluntary quality labeling in order to enter the large and growing market of discount retailers. The price-premium versus the market-entry hypothesis are analyzed theo-retically. We investigate then in an empirical hedonic pricing model for the German fruit juice market and for participation in the quality label of the Deutsche Landwirtschafts-Gesellschaft (DLG which of the two hypotheses is consistent with the data. There is strong support for the market-entry hypothesis

    Full Text Available The articles objective is to demonstrate that a socially responsible consumer is interested of being informed about Corporate Social Responsibility (CSR practices and is also willing to pay a higher price for a product made with CSR. Criteria of price as well as the interest of being informed about CSR practices were the two variables analyzed for the Chi-Square test. Even though CSR was declared as an important issue for the majority of participants, products made with CSR hasn’t achieved much influence in the buying decision making or in the need of being informed about the CSR practices. The need to create social consciousness for consumers to promote CSR practices through the buying decision making was also demonstrated.

    Evaluations of energy-price policies are necessarily based on measures of the substitution of energy and non-energy inputs. Facing a variety of substitution elasticities, the central question arises which measure would be appropriate. Apparently, for a long time, this question has not been at issue: Allen's elasticities of substitution (AES) have been the most-used measures in applied production analysis. This paper's main contribution is an instructive survey of the origin of substitution measures and of the trinity of empirical substitution elasticities-AES, cross-price elasticities, and the Morishima elasticities of substitution (MES)-with particular emphasis on their interpretations and the perspectives that will be captured by these measures. This survey clarifies why classical cross-price elasticities are to be preferred for many practical purposes. Berndt and Wood's (Rev. Econom. Stat. 57(1975) 259) frequently applied data set of US manufacturing is used to illustrate why assessments of energy-price policies would be better based on cross-price elasticities like the energy-price elasticity of capital, rather than on AES or MES.

  11. Application of the Price-Volume Approach in Cases of Innovative Drugs Where Value-Based Pricing is Inadequate: Description of Real Experiences in Italy.

    Messori, Andrea

    2016-08-01

    Several cases of expensive drugs designed for large patient populations (e.g. sofosbuvir) have raised a complex question in terms of drug pricing. Even assuming value-based pricing, the treatment with these drugs of all eligible patients would have an immense budgetary impact, which is unsustainable also for the richest countries. This raises the need to reduce the prices of these agents in comparison with those suggested by the value-based approach and to devise new pricing methods that can achieve this goal. The present study discusses in detail the following two methods: (i) The approach based on setting nation-wide budget thresholds for individual innovative agents in which a fixed proportion of the historical pharmaceutical expenditure represents the maximum budget attributable to an innovative treatment; (ii) The approach based on nation-wide price-volume agreements in which drug prices are progressively reduced as more patients receive the treatment. The first approach has been developed in the USA by the Institute for Clinical and Economic Review and has been applied to PCSK9 inhibitors (alirocumab and evolocumab). The second approach has been designed for the Italian market and has found a systematic application to manage the price of ranibizumab, sofosbuvir, and PCSK9 inhibitors. While, in the past, price-volume agreements have been applied only on an empirical basis (i.e. in the absence of any quantitative theoretical rule), more recently some explicit mathematical models have been described. The performance of these models is now being evaluated on the basis of the real-world experiences conducted in some European countries, especially Italy.

    We employ system dynamics method towards a coal-chemical industry district economy evolution model, using coal industry, the coal-chemical industry, their downstream industries, and the manufacture-related service industry. Moreover, we construct energy price and policy response scenarios based on Ordos’ management experience. The results show that the energy price slump had a negative impact on the overall economic development of the coal-chemical industry district, despite promoting non-resource industries. Furthermore, policies had different effects on the industry's output value and profit. In the long-term, developing alternative industries (AI) helps increase the industrial output value and profit. Decreasing value added tax (VAT) has immediate results and a distinctive effect on industrial short-term production value and profit, its long-term effect being limited. The effect of production limit (PL) on industrial profit is stronger than output value, and financial support (FS) is more conducive to improve the latter. However, coal mining and coal-chemical loan increases decrease the gross industrial profit level. Technology innovation (TI) has the best individual policy overall effect on production value and profits. Furthermore, the simultaneous implementation of PL, TI and AI can generate the synergy effect for each of them. And the simultaneous implementation of VAT and one or couple of other policies will generate the crowding-out effect both for VAT and other policies. - Highlights: • A system dynamics model of the coal-chemical industry district economy evolution in Ordos is constructed. • The impact of coal and oil prices slump on the output value and profit of each industry is revealed. • The differences in the effects especially cumulative effects of different response policies are clarified. • The crowding-out and synergy effects of policy implementation are analyzed.

  13. Price-structure of electricity and district-heating. A background study for energy conservation programme

    International Nuclear Information System (INIS)

    1994-01-01

    The present report deals with the pricing and price-structure of electricity and district-heating with their effects on energy saving. It constitutes part of the groundwork for the new Government Energy Conservation Programme. The report describes principles for the pricing of electricity and district-heating in Finland, and gives some examples of tariffs in foreign countries, which are interesting from the point of view of energy saving. Different utilities apply quite similar pricing principles but there are big differences in price levels between the utilities. The difference in consumer prices can be almost 100 % in the case of electricity and over 150 % as concerns district-heating. The change in retail prices in the last ten years has not had a big general impact on the consumption of electricity or on energy saving. On the other hand, when the price increases of individual utilities are studied, the impact on energy saving at least in the short term can be seen. It seems that an increase of the fixed charges in relation to energy rates has been as a general trend after 1990. To promote energy saving the changing energy rates should be given special emphasis in determining electricity and district-heating tariffs. The opening of the electricity market means that the electricity suppliers face a new situation also when pricing their products. Customers and their expectations will play an increasingly role.

  14. Oil Price and Economic Resilience. Romania’s Case

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available The emerging economies that do not face fiscal, monetary and foreign debt pressures can use the savings generated by lower oil prices for investments in order to generate economic growth. Hence, there is no doubt that the oil price affects the economy’s resilience to shocks. The importance of this impact derives from the magnitude of the price change and its diffusion within the economy. Moreover, the sustainability of any company and of the economy as a whole is subject to the availability and the price of the energy resources. The cost of these resources is an important variable used in the majority of the models regarding the assessment of sustainable development. Therefore, this article examines the impact of the oil price changes on industrial production in Romania. We found that, similar to other countries, in Romania, the growth rate of industrial production responds more strongly to a rise in oil prices. Thus, the oil Brent price has an asymmetric effect on the production evolution. This finding suggests that macroeconomic stabilization is more difficult to achieve when the oil price rises.

  16. Determinants and Sustainability of House Prices: The Case of Shanghai, China

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Recent housing policies include measures for home purchase control and shanty town redevelopment. This study proposes sustainable pricing, in that the long-run equilibrium price is determined by the fundamentals of house prices. We argue that changes in CPI might have led to rapidly growing house prices and rather high price levels. We investigate the long-run or short-run impacts of new commodity housing completions, transacted square meters of commodity housing, and CPI for house prices in Shanghai. We adopt monthly data for the period of 2005–2010. We test for unit roots using both the ADF and PP techniques and structural breaks using both the Zivot-Andrews (Model B and Perron (Model C methods. Considering Cheung-Lai and Reinsel–Ahn finite-sample corrections, the results suggest a long-run equilibrium. Housing completions negatively impact house prices in the short run. A positive volume-price relationship is suggested. Housing sales affect house prices in the short run but not vice versa. Hence, the empirical evidence supports the search model. In addition, CPI is strongly exogenous with respect to the long-run relationship and thus is a long-term determinant of house prices. CPI also positively and drastically influences house prices in the short run. Therefore, a reduction in inflation rate could stabilize house prices, increasing the chances of sustainable prices in the future.

    Directory of Open Access Journals (Sweden)

    Rafael R. Ramírez

    2016-04-01

    Full Text Available Improving water practices among small farmers in a water scarce area like the Yucatan Peninsula in Mexico is a complex task. Despite government attempts to enforce regulations and question the possibility of adjusting prices, the misuse of this scarce resource continues. Most farmers are, at best, motivated to aim for a minimum level of compliance, with very few striving to engage in best practices. This article seeks to make a proposal about the best drivers for inspiring best practices in an effort to improve the use of water management in the area. It proposes that a virtue ethics approach that explicitly focuses on the cultivation of an attitude of respect for water founded on three key principles (participation, hydrosolidarity and proactive engagement is the best solution for Yucatan. This hypothesis is the result of developing a singular methodology based on Partial Least Squares (PLS, according to structural equation modeling (SEM, that could be replicated anywhere to ascertain which measures are best suited in a particular context. Using a small sample size, this research ascertains what is required to achieve best practices with regards to the management of water in that particular area.

  18. Are electricity prices affected by the US dollar to Euro exchange rate? The Spanish case

    International Nuclear Information System (INIS)

    Munoz, M. Pilar; Dickey, David A.

    2009-01-01

    The objective of this paper is to investigate the relationships between Spanish electricity spot prices and the US dollar/Euro (USD/Euro) exchange rate during the period 2005-2007, taking into account the study of the association between dollar and oil prices, in order to better understand the evolution of the former over time. The first finding in this study is that Spanish electricity spots prices, the USD/Euro exchange rate and oil prices are cointegrated; therefore there is a long-run equilibrium relationship between the three variables. Short-run relationships have been detected between oil prices and Spanish electricity prices and USD/Euro exchange rate in the sense that Spanish electricity prices and USD/Euro exchange rate are affected by oil prices in the short run. There is a transmission of volatility between USD/Euro exchange rate and oil prices to Spanish electricity prices; so although Spanish electricity prices are not affected in level by the movements of USD/Euro exchange rate, they are in volatility. In this kind of scenario the conclusions confirm that for countries so dependent on external causes as Spain, one possible solution for guarantying the energy security would be the promotion of the renewable energies. Therefore we cannot ignore the impact in the internal expenses of the cost of installation and generation of green energies so there must be a balance between the increase in renewables and the reasonable market price of the electricity.

    Tashpulatov, Sherzod N.

    2013-01-01

    Price fluctuations that partially comove with demand are a specific feature inherent to liberalized electricity markets. The regulatory authority in Great Britain, however, believed that sometimes electricity prices were significantly higher than what was expected and, therefore, introduced price-cap regulation and divestment series. In this study, I analyze how the introduced institutional changes and regulatory reforms affected the dynamics of daily electricity prices in the England and Wales wholesale electricity market during 1990–2001. This research finds that the introduction of price-cap regulation did achieve the goal of lowering the price level at the cost of higher price volatility. Later, the first series of divestments is found to be successful at lowering price volatility, which however happens at the cost of a higher price level. Finally, this study also documents that the second series of divestments was more successful at lowering both the price level and volatility. - Author-Highlights: • The impact of regulation on the dynamics of electricity prices is examined. • Price-cap regulation has decreased the level at the cost of higher volatility. • The first series of divestments has reversed the trade-off. • The reversed trade-off is explained as an indication of tacit collusion. • The second series of divestments is found generally successful

    Full Text Available The scarcity of water is the result of the recent successive drought in most country's districts. The increase of demand due to the increase of population and also inappropriate growth of supply according to the high cost of production process and therefore distribution, arise a big concern for the water and wastewater companies. Therefore the provision of water supply for consumers emphasizes on the urge of the management policies more than ever. Knowing the consumer behavior, in this regard, is the first and the most important step. In this study, to reach this objective, the function of household water demand in structure of block pricing in Tehran was estimated by using  household budget data , through discrete – continues choice model and maximum likelihood approach . The results show that price and income parameters have expected sign. The calculated unconditional elasticties show that consumers’ sensitiveness for price fluctuations in the structure of block pricing are against zero. Therefore, the policy of price reform in the structure of block pricing can be used as an effective tool in the management of consumption.

    2017-03-01

    Full Text Available The paper analyses the association between certain macroeconomic variables and food price inflation, non-food price inflation and overall inflation in Zimbabwe, and also seeks to determine the level of association between these variables, given food security implications and overall well-being of its citizens. The study reveals that during the 2010 to 2016 period, Zimbabwe experienced stable food prices—annual food price inflation for food and non-alcoholic beverages averaged a relatively low growth rate of 0.12% monthly, while non-food inflation monthly growth rate was 0.09% and overall inflation growth rate was 0.11%. Although inflation from 2010 had been declining, of late, the increase in annual inflation has been underpinned by a rise in non-food inflation. Zimbabwe’s annual inflation remains lower than inflation rates in other countries in the region. Despite the increases lately in overall inflation, it remained below zero in January 2016, mostly driven by the depreciation of the South African rand and declining international oil prices. It should also be noted that domestic demand continued to decline in 2015, leading to the observed decline in both food and non-food prices. While food inflation has remained relatively low, it should be noted that non-food expenditures is significant component of the household budget and the rising prices result often lead to declining purchasing power and force households to make difficult choices in terms of their purchases. The findings of the study are food inflation has a low association with the independent variables under study; Zimbabwe broad money supply, rand-dollar exchange rates and the South Africa food inflation. There is, however, a very strong association between non-food inflation and these independent variables, as well as between overall inflation and the independent variables. Given the mostly rural population and the high level of unemployment in Zimbabwe, it can be surmised that

    This paper presents a stochastic factor based approach to mid-term modeling of spot prices in deregulated electricity markets. The fundamentals affecting the spot price are modeled independently and a market equilibrium model combines them to form spot price. Main advantage of the model is the transparency of the generated prices because each underlying factor and the dynamics between factors can be modeled and studied in detail. Paper shows realistic numerical examples on the forerunner Scandinavian electricity market. The model is used to price an exotic electricity derivative

  8. Economics of National Waste Terminal Storage Spent Fuel Pricing Study

    International Nuclear Information System (INIS)

    1978-05-01

    The methodology for equitably pricing commercial nuclear spent fuel management is developed, and the results of four sample calculations are presented. The spent fuel management program analyzed places encapsulated spent fuel in bedded salt while maintaining long-term retrievability. System design was reasonable but not optimum. When required, privately-owned Away From Reactor (AFR) storage is provided and the spent fuel placed in AFR storage is eventually transported to final storage. Applicable Research and Development and Government Overhead are included. The cost of each component by year was estimated from the most recent applicable data source available. These costs were input to the pricing methodology to establish a one-time charge whose present value exactly recovered the present value of the expenditure flow. The four cases exercised were combinations of a high and a low quantity of spent fuel managed, with a single repository (venture) or a multiple repository (campaign) approach to system financial structure. The price for spent fuel management calculated ranged from 116 to 152 dollars (1978) per kilogram charged initially to the reactor. The effect of spent fuel receiving rate on price is illustrated by the fact that the extremes of price did not coincide with the cases having the extremes of undiscounted cost. These prices for spent fuel management are comparable in magnitude to other fuel cycle costs. The range of variation is small because of compensating effects, i.e., additional costs for high early deliveries (AFR and transportation) versus lower present value of future revenue for later delivery cases. The methodology contains numerous conservative assumptions, provisions for contingencies, and covers the complete set of spent fuel management expenses

    Full Text Available This experimental study investigates antecedents and consequences of perceptions of price unfairness in a price increase situation. The proposed theoretical model states that consumer dependence on the service provider as well as the relevance the consumer attributes to the service (for the consumer's life will affect his/her degree of (a unfairness price perception, (b anger, and (c intention to complain and retaliate. The results support all the hypotheses specified in the model. The findings not only indicate that some situations of unfairness price perception lead to stronger emotions and more dramatic reactions from consumers, but also allow us to predict which situations of perceived unfairness offer greater risks and have greater potential for conflict.

  14. Crude oil price dynamics: A study on effects of market expectation and strategic supply on price movements

    Science.gov (United States)

    Jin, Xin

    Recent years have seen dramatic fluctuations in crude oil prices. This dissertation attempts to better understand price behavior. The first chapter studies the behavior of crude oil spot and futures prices. Oil prices, particularly spot and short-term futures prices, appear to have switched from I(0) to I(1) in early 2000s. To better understand this apparent change in persistence, a factor model of oil prices is proposed, where the prices are decomposed into long-term and short-term components. The change in the persistence behavior can be explained by changes in the relative volatility of the underlying components. Fitting the model to weekly data on WTI prices, the volatility of the persistent shocks increased substantially relative to other shocks. In addition, the risk premiums in futures prices have changed their signs and become more volatile. The estimated net marginal convenience yield using the model also shows changes in its behavior. These observations suggest that a dramatic fundamental change occurred in the period from 2002 to 2004 in the dynamics of the crude oil market. The second chapter explores the short-run price-inventory dynamics in the presence of different shocks. Classical competitive storage model states that inventory decision considers both current and future market condition, and thus interacts with spot and expected future spot prices. We study competitive storage holding in an equilibrium framework, focusing on the dynamic response of price and inventory to different shocks. We show that news shock generates response profile different from traditional contemporaneous shocks in price and inventory. The model is applied to world crude oil market, where the market expectation is estimated to experience a sharp change in early 2000s, together with a persisting constrained supply relative to demand. The expectation change has limited effect on crude oil spot price though. The world oil market structure has been studied extensively but no

  16. Pricing behaviour of pharmacies after market deregulation for OTC drugs: the case of Germany.

    Science.gov (United States)

    Stargardt, Tom; Schreyögg, Jonas; Busse, Reinhard

    2007-11-01

    To examine the price reactions of German pharmacies to changes made to OTC drug regulations in 2004. Prior to these changes, regulations guaranteed identical prices in all German pharmacies. Two years after market deregulation, 256 pharmacies were surveyed to determine the retail prices of five selected OTC drugs. A probit regression model was used to identify factors that increased the likelihood of price changes. In addition, 409 pharmacy consumers were interviewed to gather information on their knowledge of the regulatory changes and to better explain consumer behaviour. Data was collected on a total of 1215 prices. Two years after deregulation, 23.1% of the participating pharmacies had modified the price of at least one of the five OTCs included in our study. However, in total, only 7.5% of the prices differed from their pre-deregulation level. The probit model showed that population density and the geographic concentration of pharmacies were significantly associated with price changes. Interestingly, the association with the geographic concentration of pharmacies was negative. The consumer survey revealed that 47.1% of those interviewed were aware of the deregulation. Our findings indicate that, two years after deregulation, very few pharmacies had made use of individual pricing strategies; price competition between pharmacies in Germany is thus taking place only a very small scale.

    2002-01-01

    Some of the questions with respect to the trade of nitrogen oxides that businesses in the Netherlands have to deal with are dealt with: should a business buy or sell rights for NOx emission; which measures must be taken to reduce NOx emission; how much must be invested; and how to deal with uncertainties with regard to prices. Simulations were carried out with the MOSES model to find the answers to those questions. Results of some case studies are presented, focusing on the chemical sector in the Netherlands. Finally, the financial (dis)advantages of NOx trade and the related uncertainties for a single enterprise are discussed [nl

  18. Impact of regulated price adjustments on price variability in a very low inflation transition economy: Case of Armenia

    Directory of Open Access Journals (Sweden)

    Aghassi Mkrtchyan

    2005-06-01

    Full Text Available This paper examines the impact of monetary policy and administrative price adjustments on price variability in a low inflation economy characterized by relatively frequent administrative price adjustments. Fluctuations of market determined prices, prices of agricultural goods in particular, are linked to poor synchronization between administrative price changes and monetary policy. If monetary policy does not account for expected changes in administrative prices, demand for free goods shifts, causing fluctuation of prices for agricultural goods, because the supply of these goods is highly inelastic in Armenia. The findings contribute to a better understanding of agricultural price variability during 1998-2002. The impact of macroeconomic policy and structural adjustments on income distribution and rural poverty incidence are also examined. This research has immediate policy implications, since Armenia will continue to undergo major upward price adjustments of regulated prices, which may have a negative impact on income distribution unless aggregate demand management is changed.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

  1. Analysis of the imbalance price scheme in the Spanish electricity market: A wind power test case

    International Nuclear Information System (INIS)

    2013-01-01

    This work investigates the interaction between wind power and electricity markets. The paper is focused on balancing markets pricing policies. The proposal of a new imbalance price scheme is included and conveniently evaluated. This proposed scheme tries to minimise the use of ancillary services to compensate for deviations in searching for a more efficient market design. The effectiveness of imbalance prices as market signals is also examined, and policy recommendations regarding imbalance services are discussed. Two test cases are included that analyse the participation of a wind power producer in the Spanish electricity market using a stochastic optimisation strategy. For this purpose, the uncertainty of the variables is considered, i.e., wind power production and prediction, intraday and imbalance prices. Test cases were run with real data for 10 months, and realistic results are presented along with a hypothetical test case. The regulation of the imbalance prices may not be adequate for the Spanish electricity market because an error drop is not sufficiently encouraged. Therefore, we suggest the application of a new imbalance price scheme, which includes an additional constraint. The conclusions of this paper can be assumed to be general policy recommendations

    One third of the world's population lacks regular access to essential medicines partly because of the high cost of medicines. In Vietnam, the cost to patients of medicines was 47 times the international reference price for originator brands and 11 times the price for generic equivalents in the public sector. In this article, we report the results of a qualitative study conducted to identify the principal reasons for inflated medicine prices in Vietnam.Between April 2008 and December 2009, 29 semi-structured interviews were conducted with staff from pharmaceutical companies, private pharmacies, the Ministry of Health, and the Ministry of Finance of Vietnam. Study participants were recruited using a combination of purposive and snowball sampling techniques. Interviews were recorded, transcribed and coded using NVivo8® software and analyzed using a framework of structure-conduct-performance (SCP).Participants attributed high prices of originator medicines to a monopoly of supply. The prices of generic medicines were also considered to be excessive, reportedly due to the need to recoup the cost of financial inducements paid to prescribers and procurement officers. These inducements constituted a dominant cost component of the end price of generic medicines. Poor market intelligence about current world prices, as well as failure to achieve economies of scale because of unwarranted duplication in pharmaceutical production and distribution system were also factors contributing to high prices. This was reported to be further compounded by multiple layers in the supply chain and unregulated retail mark-ups.To address these problems a multifaceted approach is needed encompassing policy and legislative responses. Policy options include establishing effective monitoring of medicine quality assurance, procurement, distribution and use. Rationalization of the domestic pharmaceutical production and distribution system to achieve economies of scale is also required. Appropriate

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

    This study investigates the spatial price transmission among major wheat and rice markets of Pakistan using their monthly retail prices. For analysis Vector Error Correction Model and Co-integration approach were employed. Results showed that wheat and rice market prices are integrated. Some markets have positive or negative transmission shocks on each other due to the different geographical locations and transport infrastructure. All the wheat markets are adjusted to price changes in the long run equilibrium except few markets. Unidirectional and bidirectional causality exists between wheat and rice markets. Bad and poor infrastructure is a major impediment to price transmission among the markets. These market imperfections lead to food insecurity in the country. Government should formulate better policies and develop infrastructure towards better and efficient market function. The results of this study will help the policy makers to formulate a better policy to enhance marketing function to overcome food insecurity situation. (author)

    China is a large agricultural country, and the healthy development of agriculture is related to the stability of the whole society. The agricultural production and management of agricultural products are confronted with many risks, especially the market risks. Option contract is the object of option market transaction, so it is very important to study the option contract of agricultural products. Option trading separates the risk and profit, so that the trader can avoid the risk while retaining the opportunity to obtain income. The option has the characteristics of low transaction cost, simple and efficient, so it is suitable for small and medium investors.

    We analyze a large-scale field test conducted with a mail-order catalog firm to investigate how customers react to premium prices for larger sizes of women's apparel. We find that customers who demand large sizes react unfavorably to paying a higher price than customers for small sizes. Further investigation suggests that these consumers perceive that the price premium is unfair. Overall, premium pricing led to a 6% to 8% decrease in gross profits.

    2014-06-01

    Employing electric vehicles as short-term energy storage could improve power system stability and at the same time create a new income source for vehicle owners. In this paper, the economic viability of this concept referred to as Vehicle-to-Grid is investigated. For this purpose, a price-responsive charging and dispatching strategy built upon temporally resolved electricity market data is presented. This concept allows vehicle owners to maximize returns by restricting market participation to profitable time periods. As a case study, this strategy is then applied using the example of Singapore. It is shown that an annual loss of S 1000 resulting from a non-price-responsive strategy as employed in previous works can be turned into a S 130 profit by applying the price-responsive approach. In addition to this scenario, realistic mobility patterns which restrict the temporal availability of vehicles are considered. In this case, profits in the range of S 21-S 121 are achievable. Returns in this order of magnitude are not expected to make Vehicle-to-Grid a viable business case, sensitivity analyses, however, show that improved technical parameters could increase profitability. It is further assumed that employing the price-responsive strategy to other national markets may yield significantly greater returns.

    In an effort to relieve the pressure of drug shortages, the Chinese government implemented Low-price Medicines (LPM) policy to raise the price cap in July 2014. The purpose of this study is to examine the effect of the implementation of this policy on drug price in China. Price data of 491 LPM, including 218 low-price chemical medicines (LPCM) and 273 low-price traditional Chinese medicines (LPTCM), were collected from 699 hospitals. We used interrupted time series design to identify the variation of monthly Laspeyres Indexes (LI) and Paasche Indexes (PI) for LPM, LPCM, and LPTCM. The result demonstrated that although LPM expenditures increased, the proportion of LPM expenditures accounting for all medicine expenditures fell from 3.6% to 3.2%. After the implementation of LPM policy, there was a significant increasing trend in LPM-PI, LPCM-PI, and LPTCM-PI. The trend in LPM-LI and LPCM-LI was found from descending to rising. However, for LPTCM, the trend in the LI remained to decrease after the policy implementation. Despite the LPM policy had an increasing impact on the LPM drug price, the proportion of LPM expenditures accounting for all medicine expenditures did not increase. More efforts are needed in the future to promote the rational drug use in China. Copyright © 2018 John Wiley & Sons, Ltd.

    Full Text Available Companies can use different pricing strategies to accelerate demand. Pricing strategies not only provide information to consumers but also profoundly affect their perceptions of products and services. Price ending strategies, for example, use prices that have a psychological impact. This study sought to identify and compare different generations’ perceptions of price ending strategies using data collected via a questionnaire based on the relevant literature. The population comprised people over 18 who live in Mersin, Turkey. Quota sampling was applied so that 100 respondents were chosen from each generation (i.e., Baby Boomers and Generations X, Y, and Z and 200 people from each gender. The questionnaires were conducted face-to-face between April 15 and May 15, 2016. The data were analyzed using analysis of variance and correspondence analysis, as well as descriptive statistics. The results reveal that consumers’ perceptions of quality, discount, and image evoked by prices differ significantly by generation. The findings suggest that retail managers need to pay attention to the generational composition of their target market when using pricing strategies.

    2011-12-01

    Full Text Available In face of the global food crisis of 2007–2008, severe concerns arose about how developing countries would be affected by the extreme short-term fluctuations in international commodity prices. We examine the effects of the crisis on Bolivia, one of the poorest countries of the Americas. We focus on the effectiveness of the domestic policy interventions in preventing spillovers of the development of international food prices to domestic markets. Using a cointegration model, we study price interdependencies of wheat flour, sunflower oil and poultry. The analysis suggests that the policy measures taken had little effect on food security during the food crisis. Throughout the entire period, perfect price transmission between the Bolivian poultry and sunflower oil markets and the respective international reference markets existed. Bolivian prices were determined by international prices and the policy interventions in the markets of these two commodities were not found to have had an effect. The government’s large-scale wheat flour imports did not shield Bolivian consumers from the shocks of international prices.

    For alleviating domestic oil price when the international oil crisis happens, the government has been reacted directly such as using stored oil or alleviation fund. Although the release of stored oil works for short-term depending on the type of crisis, concerning that most of oil crisis had been resulted in temporary supply reduction rather than long-term supply suspension, utilizing the domestic alleviation fund is regarded more economical than storing oil. However, it has been suggested to compare efficiencies of alleviation fund and a futures market regarding the perspectives that using alleviation fund is more inefficient than utilizing a futures market. Moreover, the direct management by government is less efficient than indirect management. As an efficient way to alleviate domestic oil price at international oil crisis, this study presents an effective utilization of trading in futures of crude oil. There is a high probability of occurrence of this kind of oil crisis by judging from the world political situation and the trend of oil market. In such a case, the government as a crude oil importer should minimize the stored oil and utilize a futures market effectively. The subject of alleviating oil price by trading in futures is an oil supplier, such as oil refining companies or oil importers not the government as a prerequisite. Furthermore, the government should approve to include appropriate cost for preparing oil price alleviation in the oil price and it is required that such a government policy should be consistent.

  3. GLOBAL TO DOMESTIC PRICE TRANSMISSION BETWEEN THE SEGMENTED CEREALS MARKETS: A STUDY OF AFGHAN RICE MARKETS

    Directory of Open Access Journals (Sweden)

    Najibullah Hassanzoy

    2015-10-01

    Full Text Available This paper examines cointegration and the difference in the extent of price transmission, and speed of adjustment between global and domestic prices of high and low quality rice. Unit root tests, cointegration tests and error correction models are employed in the analysis. While there are no comparable studies in the literature, the findings of this study indicate that the dynamics of price transmission may be different between high and low quality rice markets. That is, the extent of price transmission appears to be larger for the global prices of low quality rice whereas the speed of adjustment to the long-run equilibrium may be faster for domestic prices of high quality rice. Moreover, a shock in the global prices of low quality rice may have a long-lasting effect on domestic prices of low quality rice as compared to their high quality counterparts affecting domestic prices of high quality rice.

  4. A Study on strengthening demand management of energy price

    Seo, Jung Hwan [Korea Energy Economics Institute, Euiwang (Korea)

    1999-02-01

    Until 1980s, energy sector had been operated as a monopoly of public enterprises in most countries. Price regulation of government had an influence on energy supply and demand by not fully giving information on market situation (supply and demand). Recently, as energy related technology and information technology have developed, the developed countries including UK and some developing countries could raise efficiency of industry through competitive market by recognizing the limit of government regulation and opening up many sectors of energy industry to the private sector. Korea is also implementing a measure for introducing competition through the participation of private sector into electricity and natural gas industries step by step. If the private sector is participated and competition is introduced, energy price cannot be a policy instrument setting up by the government, so demand management through price regulation is meaningless. Under such circumstances, a policy function should be converted to the direction of promoting competition and increasing market efficiency. In this study, it examines how the government regulation and industry has been changed through the transition of natural gas and electricity industries in UK, USA, and France and then it tries to derive suggestions to Korea.

    Aim To assess the impact of the generic reference pricing (GRP) system on the prices and cost of medicines in Slovenia approximately 8 years after its introduction in 2003 and before the implementation of the therapeutic reference pricing system. Methods A retrospective study of all medicines (N = 789) included in the GRP system on January 31, 2012 was performed. Medicine prices and cost were analyzed between January 31, 2012 and December 31, 2013 after every update (N = 11) of the maximum reimbursable price (MRP) and were compared to the price and cost on January 31, 2012 (index date). Time trends of different types of medicine prices (maximum allowed price, MRP, and actual wholesale price) were graphically analyzed, and actual wholesale price adjustments to the MRP changes and the budget impact of the GRP were assessed. Results In the 2-year study period, the long-term performance of the GRP system was associated with an approximate 45% decrease in the average MRP or an approximate 20% cost reduction. For each MRP update period, the GRP reduced the cost based on the maximum allowed price for approximately 30%. The wholesale price adjustments were mostly made for medicines priced above the MRP and reduced patients’ out-of-pocket cost. Conclusions In the long term, the GRP system effectively reduced medicine prices and the cost of reimbursed products. PMID:29740992

The Price Experiment and Modelling (Price ExaM) study aims to: I) derive accurate and precise food PE values; II) quantify the impact of price changes on quantity and quality of discrete food group purchases and; III) model the potential health and disease impacts of a range of food taxes and subsidies. To achieve this, we will use a novel method that includes a randomised Virtual Supermarket experiment and econometric methods. Findings will be applied in simulation models to estimate population health impact (quality-adjusted life-years [QALYs]) using a multi-state life-table model. The study will consist of four sequential steps: 1. We generate 5000 price sets with random price variation for all 1412 Virtual Supermarket food and beverage products. Then we add systematic price variation for foods to simulate five taxes and subsidies: a fruit and vegetable subsidy and taxes on sugar, saturated fat, salt, and sugar-sweetened beverages. 2. Using an experimental design, 1000 adult New Zealand shoppers complete five household grocery shops in the Virtual Supermarket where they are randomly assigned to one of the 5000 price sets each time. 3. Output data (i.e., multiple observations of price configurations and purchased amounts) are used as inputs to econometric models (using Bayesian methods) to estimate accurate PE values. 4. A disease simulation model will be run with the new PE values as inputs to estimate QALYs gained and health costs saved for the five policy interventions. The Price ExaM study has the potential to enhance public health and economic disciplines by introducing internationally novel scientific methods to estimate accurate and precise food PE values. These values will be used to model the potential health and disease impacts of various food pricing policy

    Excessive alcohol consumption has significant adverse economic, social, and health outcomes. Recent estimates suggest that the annual economic costs of alcohol in Australia are up to AUD $36 billion. Policies influencing price have been demonstrated to be very effective in reducing alcohol consumption and alcohol-related harms. Interest in minimum pricing has gained traction in recent years. However, there has been little research investigating the level of support for the public interest case of minimum pricing in Australia. This article describes protocol for a study exploring Western Australian (WA) public knowledge, understanding, and reaction to a proposed minimum price policy per standard drink. The study will employ a qualitative methodological design. Participants will be recruited from a wide variety of backgrounds, including ethnic minorities, blue and white collar workers, unemployed, students, and elderly/retired populations to participate in focus groups. Focus group participants will be asked about their knowledge of, and initial reactions to, the proposed policy and encouraged to discuss how such a proposal may affect their own alcohol use and alcohol consumption at the population level. Participants will also be asked to discuss potential avenues for increasing acceptability of the policy. The focus groups will adopt a semi-structured, open-ended approach guided by a question schedule. The schedule will be based on feedback from pilot samples, previous research, and a steering group comprising experts in alcohol policy and pricing. The study is expected to take approximately 14 months to complete. The findings will be of considerable interest and relevance to government officials, policy makers, researchers, advocacy groups, alcohol retail and licensed establishments and organizations, city and town planners, police, and other stakeholder organizations.

    Levell, Peter

    2015-02-01

    The paper discusses the recent decision of the UK's Office for National Statistics to replace the controversial Carli index with the Jevons index in a new version of the retail price index-RPIJ. In doing so we make three contributions to the way that price indices should be selected for measures of consumer price inflation when quantity information is not available (i.e. at the 'elementary' level). Firstly, we introduce a new price bouncing test under the test approach for choosing index numbers. Secondly, we provide empirical evidence on the performance of the Carli and Jevons indices in different contexts under the statistical approach. Thirdly, applying something analogous to the principle of insufficient reason, we argue contrary to received wisdom in the literature, that the economic approach can be used to choose indices at the elementary level, and moreover that it favours the use of the Jevons index. Overall, we conclude that there is a case against the Carli index and that the Jevons index is to be preferred.

    Full Text Available Islamic banking is based on profit and loss mechanism where the use of interest is prohibited.  Unlike conventional banks, these banks do not charge a specific rate of interest, rather provides financing in exchange for profit sharing.  However, there are studies claiming that, in practice, Islamic banking is same as conventional banking with regard to the use of interest. It is also claimed that, Islamic deposits are not interest-free, but are closely attached to conventional deposits.   On this background, the objective of this study is to examine the relationship between pricing in Islamic banks vis-à-vis conventional banks by taking the case of Bangladesh. We have used monthly data during the period of 2009-2013. The findings of the study showed that, there is no statistically significant difference between the monthly average lending rates of Islamic banks and conventional banks. However, there is significant difference between deposit rates. The existence of causal relationship was inconclusive, and requires further analysis.

  18. The potential for greenhouse gases mitigation in household sector of Iran: cases of price reform/efficiency improvement and scenario for 2000-2010

    Iran's demographic profile is sharply youth oriented and this upcoming generation's needs for employment and housing, coupled with low-energy efficiency vectors and consumption patterns, has created a constant rise in energy demand and greenhouse gas (GHGs) emissions in the residential sector. Improved energy efficiency as a national policy lynchpin for demand reduction and GHGs mitigation, has become commonplace. OPEC countries however, Iran included, suffer an obvious lack of consumer incentive because of low fuel prices. This study evaluates the twin impacts of price reform and efficiency programs on energy carriers' consumption and GHGs mitigation in the Iranian housing sector. For this purpose, the demand functions for energy carriers, has been developed by econometrics process models. The results reveal that price elasticity for electricity demand in the Constant Elasticity Model for the short-run while the long-run is -0.142 and -0.901, respectively. In the Variable Elasticity Model the 250% increase in electricity rates in the short-run resulted in a price elasticity change from -0.02 to -0.475, hence the 250% increase in electricity pricing for the long-run resulted in the price elasticity change from -0.15 to -2.0. Finally, aided by a Scenario-Based Approach the impact of fuel pricing and efficiency improvement in trends of energy demand and GHGs emission were assessed in a Scenarios Base, developed on two different cases of Business-as-Usual (BAU) and Management. The results indicate that in the BAU case between 2000 and 2011, the energy demand and CO 2 emission increases with an annual growth rate of 7.5% and 6.8%, respectively. Comparatively, if the energy carriers' price is increased to border price and energy efficiency programs are implemented, they will stimulate carriers' demand and CO 2 emissions growth rate decreases to 4.94% and 3.1%, respectively

  19. PROCESS OF GLOBAL SHOCKS TRANSMISSION TO DOMESTIC FOOD PRICE LEVEL: CASE OF BANGLADESH

    2014-04-01

    Full Text Available The world experienced in dramatic price surge of food commodities since mid of 2007 to 2008. It was claimed that the crisis were being mainly for backdrop of global shocks in food and energy price. But how the shocks come to domestic market from external sources is a researchable phenomenon. Surprisingly few attempts have been made to systematically analysis of shock transmission from international to domestic market. The study analyzed the effect of global commodity market factors and domestic exchange rate development on domestic food price in Bangladesh. A bi-variants co-integration approach was applied for the analysis of shock transmission. Finally an error correction model was developed. The overall magnitudes of the pass through suggest that only 46 per cent of the total world shock pass-through in domestic economy.

    Over the past decade, electronic markets based on the Internet, particularly online auctions, have become popular venues for conducting business. Previous studies often focused on the construction of the best bidding model, while few studies have tried to integrate multiple pricing strategies to predict the probability of closing an auction and the price premium. This study constructs a mediated model to examine the relationship among pricing strategies, the strength of bidding intentions, and online auction performance. The sample consists of 1,055 auctions of iPod MP3 players from eBay Web sites in Hong Kong, Singapore, Belgium, and France. Empirical results show that the pricing strategies directly influence both the probability of closing an auction and the level of price premium. The pricing strategies also indirectly influence the price premium through the mediating effect of the strength of bidding intentions.

    2017-06-01

    We consider a stochastic model of changes of prices in real estate markets. We suppose that in a book of prices the changes happen in points of jumps of a Poisson process with a random intensity, i.e. moments of changes sequently follow to a random process of the Cox process type. We calculate cumulative mathematical expectations and variances for the random intensity of this point process. In the case that the process of random intensity is a martingale the cumulative variance has a linear grows. We statistically process a number of observations of real estate prices and accept hypotheses of a linear grows for estimations as well for cumulative average, as for cumulative variance both for input and output prises that are writing in the book of prises.

  4. Basic Studies on Chaotic Characteristics of Electric Power Market Price

    Science.gov (United States)

    Takeuchi, Yuya; Miyauchi, Hajime; Kita, Toshihiro

    Recently, deregulation and reform of electric power utilities have been progressing in many parts of the world. In Japan, partial deregulation has been started from generation sector since 1995 and partial deregulation of retail sector is executed through twice law revisions. Through the deregulation, because electric power is traded in the market and its price is always fluctuated, it is important for the electric power business to analyze and predict the price. Although the price data of the electric power market is time series data, it is not always proper to analyze by the linear model such as ARMA because the price sometimes changes suddenly. Therefore, in this paper, we apply the methods of chaotic time series analysis, one of non-linear analysis methods, and investigate the chaotic characteristics of the system price of JEPX.

  5. Study on Comparison of Bidding and Pricing Behavior Distinction between Estimate Methods

    Science.gov (United States)

    Morimoto, Emi; Namerikawa, Susumu

    The most characteristic trend on bidding and pricing behavior distinction in recent years is the increasing number of bidders just above the criteria for low-price bidding investigations. The contractor's markup is the difference between the bidding price and the execution price. Therefore, the contractor's markup is the difference between criteria for low-price bidding investigations price and the execution price in the public works bid in Japan. Virtually, bidder's strategies and behavior have been controlled by public engineer's budgets. Estimation and bid are inseparably linked in the Japanese public works procurement system. The trial of the unit price-type estimation method begins in 2004. On another front, accumulated estimation method is one of the general methods in public works. So, there are two types of standard estimation methods in Japan. In this study, we did a statistical analysis on the bid information of civil engineering works for the Ministry of Land, Infrastructure, and Transportation in 2008. It presents several issues that bidding and pricing behavior is related to an estimation method (several estimation methods) for public works bid in Japan. The two types of standard estimation methods produce different results that number of bidders (decide on bid-no bid strategy) and distribution of bid price (decide on mark-up strategy).The comparison on the distribution of bid prices showed that the percentage of the bid concentrated on the criteria for low-price bidding investigations have had a tendency to get higher in the large-sized public works by the unit price-type estimation method, comparing with the accumulated estimation method. On one hand, the number of bidders who bids for public works estimated unit-price tends to increase significantly Public works estimated unit-price is likely to have been one of the factors for the construction companies to decide if they participate in the biddings.

    2014-08-01

    Full Text Available Researchers pay more and more attention on the price comovement-effect among international stock markets. This paper deals with the transmission mechanism of price shocks among three stock markets of China, Russia and India, with a sample of weekly returns. The results showed that the price fluctuation of each market has an influence on other markets, although the price behavior is significantly independent. The impact of external price innovations will last 5 or 6 weeks usually and disappear after about 8 weeks. The pattern of transmission-mechanism for the price shocks is very different from each other. Besides, a further study revealed that the influence of external shocks on the domestic stock price increased significantly among the three markets after the 2008 international financial crisis.

    Full Text Available Oil prices may have an impact on economic activity through various transmission channels. A number of recent studies have emphasized the role of oil prices and macro-economic variables. The aim of this paper is to study the short-term/longterm relationship between oil prices and unemployment in Turkey. The most common cause of increasing oil prices over the last thirty years has been a decrease in supply. Prices increased during the early 1970s as OPEC reduced supply. Again prices increased in the late 1970s and early 1980s as the collapse of the government of the Shah of Iran and subsequent war between Iran and Iraq threatened supply. We applied Granger causal modals to determine if oil prices “Granger Caused” unemployment for data between 2005:01 and 2009:12 in Turkey. However, we performed Vector Autoregressive Model (VAR to determine the relationship between to variables in question, to estimate these relationships and to determine the delay values. As a result, long-term relationship between oil prices and unemployment rate are available in Turkey, and changes in the unemployment rate do not affect oil prices, oil prices changes affect the unemployment rate (this effect is the opposite direction

    High prices are expected for high demand times in the electricity markets and vice versa. The System Capacity Margin (SCM) demonstrates the abundance of electricity in the market. Naturally, higher SCM causes to lower price but, the players' behavior distortions have been frequently addressed...... in the literature. The overall producers’ bidding behaviors participating in Iran Electricity Market (IEM) as the low wind penetrated case and the Danish Electricity Market (DEM) as a high wind penetrated case are studied in this paper. An index is introduced to describe the overall market players’ behaviors....... Considering the players' behavior and using adaptive Neuro-fuzzy inference system, a model is derived. Although the total trend of prices is descending while the SCM increases, the results show some unexpected behaviors in IEM. Finally, players' biding behavior are compared in DEM and IEM.

  9. Mass and energy-capital conservation equations to study the price evolution of non-renewable energy resources

    International Nuclear Information System (INIS)

    Gori, F.

    2006-01-01

    Mass conservation equation of non-renewable resources is employed to study the resources remaining in the reservoir according to the extraction policy. The energy conservation equation is transformed into an energy-capital conservation equation. The Hotelling rule is shown to be a special case of the general energy-capital conservation equation when the mass flow rate of extracted resources is equal to unity. Mass and energy-capital conservation equations are then coupled and solved together. It is investigated the price evolution of extracted resources. The conclusion of the Hotelling rule for non-extracted resources, i.e. an exponential increase of the price of non-renewable resources at the rate of current interest, is then generalized. A new parameter, called 'Price Increase Factor', PIF, is introduced as the difference between the current interest rate of capital and the mass flow rate of extraction of non-renewable resources. The price of extracted resources can increase exponentially only if PIF is greater than zero or if the mass flow rate of extraction is lower than the current interest rate of capital. The price is constant if PIF is zero or if the mass flow rate of extraction is equal to the current interest rate. The price is decreasing with time if PIF is smaller than zero or if the mass flow rate of extraction is higher than the current interest rate. (author)

  10. Study on the expropriation (requisition) price of cultivated land in China: take Nanyang City, Henan Province as an example

    2009-10-01

    With currently China's farmland transformation for non-agricultural advancement is speeding up, such disadvantages as low standard and simplified mode of compensation obviously appears in our land expropriation (requisition) system. And land expropriation (requisition) price has been distorted seriously, which has caused a series of social problems aroused more attention from many fields. It's high time to establish new criteria of land compensation. This paper presents a new method to analyze the compensation standard of cultivated-land Expropriation and requisition respectively through defining and normalize the connotation of tenure system and relevant rights of cultivated land in China, and to explore the value composition of rights over cultivated land. Methods of logic analysis, comparison and empirical analysis were applied. The results show that the tenure system of cultivated land is composed of five parts: natural productive price, social security price, social stabilization price, ecological security price and development right price. The values of all these rights vary under different socio-economic conditions, and they have to be embodied gradually in the process of land Expropriation and requisition. Moreover, the new proposed methodology has been applied to a case study of paddy lands located in Nanyang City, Henan Province in order to demonstrate its goodness. From the results of this work we can conclude that the approach proposed stands out as a good alternative to current compensation standard of cultivated-land Expropriation (requisition).

    In individual companies, price is one significant factor in achieving marketing success. In many purchase situations, price can be of great importance to customers. Marketers must establish pricing strategies that are compatible with the rest of the marketing mix. Management should decide whether to charge the same price to all similar buyers of identical quantities of a product (a one-price strategy) or to set different prices (a flexible price strategy).

    2013-03-01

    Full Text Available The aim of this paper was to analyze the degree of change in price and co- movement of prices between markets. The distinctiveness of the study is that it introduced a single product (highly perishable product price relationship analysis between a pair of spatially separated markets in the countries of the Western Balkan. This study attempts to comprehend to what extent the Macedonian domestic market is integrated into the regional markets, as well as to understand the relationship between the spatially separated regional markets. The data refer to the domestic Macedonian market and four different regional markets (Croatia, Serbia, Kosovo and Montenegro, as major importers of Macedonian fresh tomatoes. These countries were part of a common market until the 1990s and in the past period transited to a market economy. The method used is common time series analysis through unit root test, co-integration test and causality test. The study showed that the Macedonian economy, especially in terms of the tomato industry, is highly vulnerable and dependant on external markets. Future developments do not only depend upon the advances in the country, but also on developments in the export destinations. This also applies to the other concerned countries in the regions. The main finding is that a small country such as Macedonia is absorbed by developments in other countries in the region. This finding is supported by the results of the study that demonstrated a high level of co-integration between the domestic and regional markets.

    An equilibrium displacement framework was developed to evaluate the effect of exchange rate linked subsidies for non-price export promotion for US cotton. Study results show that an increase in promotion expenditure increased the dollar value and producer welfare of cotton growers. The gross gain to the domestic cotton producers from the exchange-rate linked subsidy scheme was positive. These evidences support exchange rate linked subsidies for US cotton export promotion.

  15. Renewable energies and their effect on electricity prices: the case of the German nuclear phase-out

    Energy Technology Data Exchange (ETDEWEB)

    Comtesse, Daniel; Schroeer, Sebastian

    2010-07-01

    The aim of this article is to analyze the price effects of the market integration of renewable energies. Previous related studies describe a so-called 'merit order-effect', implying that decreasing electricity prices are caused by an increasing share of renewable energies. However, this is a static effect resulting from the assumption that the existing power plant fleet remains constant. Our contribution is to analyze the long-run price effect of the substitution of renewable energies for existing technologies like nuclear power, coal or gas. This aspect is relevant, since more and more countries increase the share of renewable energies in order to substitute fossil or nuclear power plants. Higher market shares of renewable energies are caused both by their increasing competitiveness and by political actions such as national targets or promotion schemes. Background and Stylized facts Since renewable energies usually have a lower marginal price of electricity generation - which determines the electricity prices at spot markets - their addition to an established power plant fleet consisting of nuclear, coal, lignite and gas power plants leads to lower electricity prices. However, the long-run price effect when fossil or nuclear power plants are substituted remains ambiguous. This is due to the fact that, if compared to fossil and nuclear fuels, renewable energies are characterized by three specific features: firstly, they lack the ability to secure base load. Secondly, they produce energy which is extremely volatile. Thirdly, their marginal costs of production are close to zero. These characteristics are caused by the high dependency of renewable energies on weather conditions. As electricity generation and consumption must happen simultaneously (electricity storage does not pay off yet), power plants with low base load capacity need back-up capacities. Given the actual technological state of the art, these back-up capacities must be fossil or nuclear power

  16. 73 Activity Based Costing and Product Pricing Decision: the Nigerian Case

    Directory of Open Access Journals (Sweden)

    Ebipanipre Gabriel Mieseigha

    2014-06-01

    Full Text Available This paper examined activity based costing and product pricing decisions in Nigeria so as to ascertain whether activity based costing have the ability to enhance profitability and control cost of manufacturing firms. Towards this end, a multiple correlation and regression estimation technique was used in analyzing the data obtained in the study. The study found that activity based costing affects product costing and pricing decision. In addition, the results showed that improved profitability and cost control can be achieved by implementing activity based costing approach by manufacturing firms. The implication is that traditional costing approach fails in many pricing situations by arbitrarily allocating indirect cost and activity based costing helps in allocating indirect cost accurately. Thus, it was recommended amongst others that activity based costing need to be practiced, maintained and implemented by manufacturing firms since it has a broad range of uses for a wide variety of company functions and operations in the area of process analysis, strategy support, time-based accounting, monitoring wastage, as well as quality and productivity management.

  17. Government policy uncertainty and stock prices: The case of Australia's uranium industry

    Ferguson, Andrew; Lam, Peter

    2016-01-01

    We investigate effects of government policy uncertainty on stock prices, reflecting tension between ‘private interest’ (economic benefits) and ‘public interest’ arguments over uranium mining. Using a sample of Australian-listed uranium firms from January 2005 through June 2008, we document a positive contemporaneous correlation between stock returns and volatility and two measures of government policy uncertainty, proxied by the spread in voters' opinion polls between the two major political parties and a news-based sentiment index. Event-study results show significant stock price reactions to key uranium-related policy events, with cross-sectional variation in event returns predicted by models incorporating firm- and project-level characteristics. Our research design and findings may inform future research on the capital market effects of government policy uncertainty in other regulated industries. - Highlights: • Government policy uncertainty has direct effects on stock prices of uranium explorers. • Stock returns are positively related to the spread in two-party-preferred voting intention. • Stock volatility is positively related to a uranium news-based sentiment index. • Event-study results show significant market reaction to key uranium policy events.

  19. A study of the improvement of the district heat price cap system

    Energy Technology Data Exchange (ETDEWEB)

    Yoo, S.J. [Korea Energy Economics Institute, Euiwang (Korea)

    2001-11-01

    This study proposes revision of the price cap mechanism applied to the district heating company, which was introduced in 1999. The revision aims at the provision of the incentives to lower the production cost to the heat producers and preventing the monopoly price from being charged to the consumer. It is proposed to extend the application period of the price cap to 3 or 5 years. 3 year application period is recommended because of lack of the experiences of the price cap mechanism and information of its performance in the public utility industries in Korea. The calculation of the price cap is better to be set based upon the minimum of the full cost of heat production in the last year of the previous application periods or the prices actually charged to the consumer during the previous application period. As the opportunity cost of the equity capital, the interest rate of the 5 year government bond or the actual interest cost of the debt financed capital is recommended to increase the share of the equity capital and to reflect the investment risk of the district heating industry. Production efficiency index applicable to the district heating company is estimated with 3 different methods. Among three different results, 3% is the first choice from a conservative perspective. It is also recommended to adjust production efficiency index as the data are accumulated and to be implemented with a profit sharing mechanism between the consumer and the monopoly supplier. In application of the price index, producer price index is applicable if the price cap is calculated from the full production cost. consumer price index is applicable if the price cap is set from the previous year's actual district heat prices (tariffs). Transfer of the ownership either by transferring stocks or by asset selling could affect the price cap determined by the full cost of the district heat production. In order to keep the consumer's welfare from being decreased, it is necessary to set

  2. Method for Developing Descriptions of Hard-to-Price Products: Results of the Telecommunications Product Study

    Energy Technology Data Exchange (ETDEWEB)

    Conrad, F.; Tonn, B.

    1999-05-01

    This report presents the results of a study to test a new method for developing descriptions of hard-to-price products. The Bureau of Labor Statistics (BLS) is responsible for collecting data to estimate price indices such as the Consumers Price Index (BLS) is responsible for collecting data to estimate price indices such as the Consumers Price Index (CPI). BLS accomplishes this task by sending field staff to places of business to price actual products. The field staff are given product checklists to help them determine whether products found today are comparable to products priced the previous month. Prices for non-comparable products are not included in the current month's price index calculations. A serious problem facing BLS is developing product checklists for dynamic product areas, new industries, and the service sector. It is difficult to keep checklists up-to-date and quite often simply to develop checklists for service industry products. Some people estimates that upwards of 50 % of US economic activity is not accounted for in the CPI

  3. The Questionable Economic Case for Value-Based Drug Pricing in Market Health Systems.

    Science.gov (United States)

    Pauly, Mark V

    2017-02-01

    This article investigates the economic theory and interpretation of the concept of "value-based pricing" for new breakthrough drugs with no close substitutes in a context (such as the United States) in which a drug firm with market power sells its product to various buyers. The interpretation is different from that in a country that evaluates medicines for a single public health insurance plan or a set of heavily regulated plans. It is shown that there will not ordinarily be a single value-based price but rather a schedule of prices with different volumes of buyers at each price. Hence, it is incorrect to term a particular price the value-based price, or to argue that the profit-maximizing monopoly price is too high relative to some hypothesized value-based price. When effectiveness of treatment or value of health is heterogeneous, the profit-maximizing price can be higher than that associated with assumed values of quality-adjusted life-years. If the firm sets a price higher than the value-based price for a set of potential buyers, the optimal strategy of the buyers is to decline to purchase that drug. The profit-maximizing price will come closer to a unique value-based price if demand is less heterogeneous. Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

  4. Forecasting ability of the investor sentiment endurance index: The case of oil service stock returns and crude oil prices

    International Nuclear Information System (INIS)

    He, Ling T.; Casey, K.M.

    2015-01-01

    Using a binomial probability distribution model this paper creates an endurance index of oil service investor sentiment. The index reflects the probability of the high or low stock price being the close price for the PHLX Oil Service Sector Index. Results of this study reveal the substantial forecasting ability of the sentiment endurance index. Monthly and quarterly rolling forecasts of returns of oil service stocks have an overall accuracy as high as 52% to 57%. In addition, the index shows decent forecasting ability on changes in crude oil prices, especially, WTI prices. The accuracy of 6-quarter rolling forecasts is 55%. The sentiment endurance index, along with the procedure of true forecasting and accuracy ratio, applied in this study provides investors and analysts of oil service sector stocks and crude oil prices as well as energy policy-makers with effective analytical tools

    The object of this study is to suggest some improvements on current price formulas on oil and gas which have been pivotal roles in the process of Korean economic growth. This study first examines basic frames and transition of oil and gas pricing in Korea and then finds some suggestions on them by scrutinizing their theoretical backgrounds. This study finds several problems on oil and gas pricing formulas. (a) In a model that is now studied to evaluate the current domestic oil price, the costs associated with oil security such as oil stockpile are fully penetrated into oil price without their fair evaluations. There is no evaluation principle on the costs occurred in oil supply security. (b) The Rate Of Equity(ROE), a crucial factor in town-gas pricing which is strictly controlled, is directly connected to the average interest rate on saving accounts of domestic commercial banks. Some arguments may have rise about inclusion a risk factor on ROE in order to compensate the uncertainty of town-gas business. (c) New demand for natural gas which is generated by new technologies or machinery and tools can help reduce the costs occurred from seasonal imbalance between power sector and gas sector. So it is also important to decide how to include the beneficiary of cost reduction in town-gas pricing. In order to evaluate the proper price levels, this study tests energy supply security by adopting methodologies such as Herfindahl Index and Portfolio Variance Risk. They can help develop the method to effectively improve the energy security and include the proper energy security costs into energy prices. This study also provides some suggestions for betterment of current ROE decision rule in town-gas business and for improvement of current town-gas policy that government subsidizes newly developed demand for strengthening price competitiveness in the early stage.

    2013-01-01

    Full Text Available In case of price-regulated companies it is the role of appropriate government agencies to introduce clear, internally consistent, theoretically sound, and unambiguous methodology for finding the regulative cost of capital. The aim of the paper is to describe and analyze the cost of capital estimation methodology for regulated companies in Estonia and discuss some issues arising in applying this methodology. The current paper focuses on two topical issues associated with the estimation of regulative cost of capital in Estonia: estimation of market risk premium and inclusion of currency risk premium into the cost of capital. Current turmoil in financial markets has increased investors’ risk aversion as well as level of risks.

    Background: Cigarette price increases effectively prevent smoking initiation and reduce cigarette consumption among young smokers. However, the impact of cigarette prices on smoking cessation among older smokers is less clear, particularly for those aged 65 years and older, a group that is at highest risk of smoking-related disease and will almost double in the United States between 2012 and 2050. Methods: Biennial questionnaires administered between 1997 and 2013 assessed smoking status for 9,446 Cancer Prevention Study-II Nutrition Cohort participants who were ≥50 years old and lived in Washington, DC, and 48 states. For each interval between biennial questionnaires, change in price per pack and average price level per pack were calculated. The separate associations between these price variables and smoking cessation during the same time interval were determined. Results: In multivariable-adjusted models, each $1.00 price increase was associated with a 9% higher rate of quitting [rate ratio (RR) = 1.09; 95% confidence interval (CI), 1.04-1.14). Each $1.00 increase in average price was associated with a 6% higher rate of quitting (RR = 1.06; 95% CI, 1.02-1.10). The association with average price was strongest among smokers aged 65 years and older (RR = 1.07; 95% CI, 1.04-1.11) and, for price change, for smokers with no major prevalent disease (RR = 1.13; 95% CI, 1.07-1.19). Conclusions: These results suggest that increasing cigarette prices will promote quitting even among smokers aged 65 years and older. Impact: Increasing cigarette prices through higher taxes could reduce smoking rates among older adults and decrease risk of smoking-related cancers and diseases in this high-risk group.

  9. Testing optimal punishment mechanisms under price regulation : the case of the retail market for gasoline

    International Nuclear Information System (INIS)

    Gagne, R.; Versaevel, B.

    2003-01-01

    The effects of a price floor on price wars in the retail market for gasoline were analyzed. The authors selected a theoretical model which assumed a Bertrand oligopoly supergame, where firms initially collude by charging the monopolistic price. Once a deviation from this strategy is detected by the firms, a switch to a lower price is made in what can be called a punishment phase (price war), before returning to collusive prices. A natural experiment for the testing of the model was provided by the introduction of a price floor regulation in the Quebec retail market for gasoline in 1996. A Markov Switching Model with two latent states was used to simultaneously identify the periods of price-collusion/price war, and also to estimate the parameters which characterized each state. The results indicated that the intensity of price wars was reduced by the introduction of the price floor, but the expected duration of those wars was raised. 14 refs., 5 tabs., 1 fig

    Pricing policies such as taxes and subsidies are important tools in preventing and controlling a range of threats to public health. This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies. PMID:24028228

  13. Medium-Term Probabilistic Forecasting of Extremely Low Prices in Electricity Markets: Application to the Spanish Case

    Directory of Open Access Journals (Sweden)

    Antonio Bello

    2016-03-01

    Full Text Available One of the most relevant challenges that have arisen in electricity markets during the last few years is the emergence of extremely low prices. Trying to predict these events is crucial for market agents in a competitive environment. This paper proposes a novel methodology to simultaneously accomplish punctual and probabilistic hourly predictions about the appearance of extremely low electricity prices in a medium-term scope. The proposed approach for making real ex ante forecasts consists of a nested compounding of different forecasting techniques, which incorporate Monte Carlo simulation, combined with spatial interpolation techniques. The procedure is based on the statistical identification of the process key drivers. Logistic regression for rare events, decision trees, multilayer perceptrons and a hybrid approach, which combines a market equilibrium model with logistic regression, are used. Moreover, this paper assesses whether periodic models in which parameters switch according to the day of the week can be even more accurate. The proposed techniques are compared to a Markov regime switching model and several naive methods. The proposed methodology empirically demonstrates its effectiveness by achieving promising results on a real case study based on the Spanish electricity market. This approach can provide valuable information for market agents when they face decision making and risk-management processes. Our findings support the additional benefit of using a hybrid approach for deriving more accurate predictions.

    The Purchase price report released in August 2004 by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (Global Fund) was the first publication of a significant amount of real transaction purchase data for antiretrovirals (ARVs). We did an observational study of the ARV transaction data in the Purchase price report to examine the procurement behaviour of principal recipients of Global Fund grants in developing countries. We found that, with a few exceptions for specific products (e.g. lamivudine) and regions (e.g. eastern Europe), prices in low-income countries were broadly consistent or lower than the lowest differential prices quoted by the research and development sector of the pharmaceutical industry. In lower middle-income countries, prices were more varied and in several instances (lopinavir/ritonavir, didanosine, and zidovudine/lamivudine) were very high compared with the per capita income of the country. In all low- and lower middle-income countries, ARV prices were still significantly high given limited local purchasing power and economic strength, thus reaffirming the need for donor support to achieve rapid scale-up of antiretroviral therapy. However, the price of ARVs will have to decrease to render scale-up financially sustainable for donors and eventually for governments themselves. An important first step in reducing prices will be to make available in the public domain as much ARV transaction data as possible to provide a factual basis for discussions on pricing. The price of ARVs has considerable implications for the sustainability of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) treatment in the developing world.

  15. Price and access charge discrimination in electricity distribution: an application to the Chilean case

    International Nuclear Information System (INIS)

    Raineri, R.; Giaconi, P.

    2005-01-01

    This paper presents and analyzes a model of electricity distribution in Chile with three alternative regulatory pricing contract schemes for assigning a common capacity cost to final customers and competitive energy sellers. The first scheme involves Ramsey Pricing, while under the second and third schemes the monopoly chooses final prices and access charges subject either to a peak-load Physical Cap or a total revenue Price Cap constraint. In addition, we consider circumstances in which the regulator does not know consumer demand, the monopoly cannot price discriminate beyond a range defined by the marginal cost as a floor and the stand-alone cost as a ceiling, and access charges are set at the fully distributed cost allocation level currently in force. The model is calibrated with Chilean data, and demonstrates that in terms of social welfare the fully distributed cost contract scheme currently in effect can be improved by discriminatory pricing complemented by certain of the analyzed constraints.

    This paper uses individual house transaction data from 1995 to 2014 in Amsterdam to explore the risks and interrelationships of the subdistrict house prices. Simple indicators suggest that house prices grow faster and are more risky in the central business district and its immediate surrounding areas than in the peripherals. Furthermore, we observe an over time decreasing intervariations between the subdistrict house price growth rates, whereas we find a lead-lag and house price causal flow from the more central to the peripheral subdistricts.

    The growing demand for high-tech products has resulted in strong growth in demand for certain minor metals. In combination with production concentrated in China, this caused strong and unpredicted price movements in recent years. As a result, manufacturing companies have to cope with additional risks. However, the detailed reasons for the price development are only partially understood. Therefore, we analyzed empirically which determinants can be assigned to price movements and performed an event study on the high-tech metals neodymium, indium, and gallium. Based on our dataset of news items, we were able to find coinciding events to almost 90% of all price jumps (recall). We showed that if any information about these events occurred with a probability of over 50% there would also be a price jump within 10 days (precision). However, the classical set of price determinants has to be extended for these specific markets, as we found unorthodox factors like holidays or weather that may be indicators for price movements. Therefore, we hope that our study supports industry for instance in performing more informed short-term planning of metals purchasing based on information about specific events.

    2009-09-01

    This study presents a comparison of medical material prices, discusses why differences exist, and examines methods for comparing prices. Market prices for drug-eluting stents (DES), non-drug-eluting stents (non-DES), and percutaneous transluminal coronary angioplasty (PTCA) catheters were collected from five countries: the United States, Japan, Korea, Turkey, and Thailand. To compare prices, three adjustment methods were used: currency exchange rates, purchasing power parity (PPP), and gross domestic product (GDP) per capita. The ratios of medical material prices compared with those in the United States were higher in Japan (from 1.4 for DES to 5.0 for PTCA catheters) and Korea (from 1.2 for DES to 4.0 for PTCA catheters), and lower in Turkey (from 0.8 for non-DES to 1.4 for DES) and Thailand (from 0.5 for non-DES to 1.3 for PTCA catheters). The PPP-adjusted ratios changed slightly for Japan, Korea, and Turkey. When the prices were adjusted by GDP per capita, the ratios were much higher. Comparing prices using currency exchange rates or PPP is applicable only between countries with stable economic relations; adjustment by GDP per capita reflects the actual burden. Further study is needed to fully elucidate the factors influencing the global medical material market.

    2006-05-01

    Our objective is to estimate the relative price elasticity of demand for malt liquor beer (MLB), regular beer, hard liquor, and a combined group of all other alcoholic beverages. Three hundred and twenty-nine alcohol consumers (mostly male) in South-Central Los Angeles answered a series of questions pertaining to expected consumption responses to hypothetical price increases. We found that based on a 10% price increase, the mean price elasticity of demand (% change in quantity demanded / % change in price) was -0.79 for MLB drinkers, -1.14 for regular beer drinkers, -1.11 for hard liquor drinkers, and -1.69 for the combined group of all other drinkers. Logistic regression analysis revealed that the personal characteristics significantly related to being a MLB drinker were older age, not working, being homeless, and a daily drinker. Daily (or nearly daily) drinkers were more likely to be married, earning lower incomes, and hard liquor drinkers. This study is the first to investigate the price elasticity of demand for MLB drinkers and other heavy alcohol consumers in poor urban neighborhoods of the US. Future research can use the methods from this pilot study to more rigorously examine and compare the price sensitivity among heavy drinking groups.

    Full Text Available This study compared the in-sample forecasting accuracy of three forecasting nonlinear models namely: the Smooth Transition Regression (STR model, the Threshold Autoregressive (TAR model and the Markov-switching Autoregressive (MS-AR model. Nonlinearity tests were used to confirm the validity of the assumptions of the study. The study used model selection criteria, SBC to select the optimal lag order and for the selection of appropriate models. The Mean Square Error (MSE, Mean Absolute Error (MAE and Root Mean Square Error (RMSE served as the error measures in evaluating the forecasting ability of the models. The MS-AR models proved to perform well with lower error measures as compared to LSTR and TAR models in most cases.

    The purpose of this quantitative ex post facto research study was to explore the relationship between green initiative expense disclosures and stock prices of 46 NASDAQ listed Clean Edge Green Energy global companies from 2007 to 2010. The independent variables were sales and marketing, environmental, customer and supplier, community, and corporate governance practices that were correlated with the dependent variable in the study of stock prices. Expense disclosures were examined in an effort to measure the impact of green initiative programs and to expose the interrelationships between green initiative expense disclosures and fluctuations of stock prices. The data for the research was secondary data from existing annual reports. A statistically significant relationship was revealed between environmental practices and changes in stock prices. The study results also provided substantial evidence for leadership and managerial decision making to reduce or increase green initiative practices to maximize shareholder wealth of their respective organizations.

    Fiscal interventions to improve population diet have been recommended for consideration by many organisations including the World Health Organisation and the United Nations and policies such as sugar-sweetened beverage taxes have been implemented at national and sub-national levels. However, concerns have been raised with respect to the differential impact of fiscal interventions on population sub-groups and this remains a barrier to implementation. To examine how personal characteristics (such as socioeconomic status, sex, impulsivity, and income) moderate changes in purchases of targeted foods in response to food and beverage price changes in experimental settings. Systematic review. Online databases (PubMed, EMBASE, Web of Science, EconLit and PsycInfo), reference lists of previous reviews, and additional data from study authors. We included randomised controlled trials where food and beverage prices were manipulated and reported differential effects of the intervention on participant sub-groups defined according to personal characteristics. Where possible, we extracted data to enable the calculation of price elasticities for the target foods by personal characteristic. 8 studies were included in the review. Across studies, the difference in price elasticity varied from 0.02 to 2.43 between groups within the same study. 11 out of the total of 18 comparisons of own-price elasticity estimates by personal characteristic differed by more than 0.2 between groups. Income related factors were the most commonly considered and there was an indication that own-price elasticity estimates do vary by income but the direction of this effect was not clear. Experimental studies provide an opportunity to examine the differential effects of fiscal measures to improve population diets. Patterns in price sensitivity by personal characteristics are complex. General conclusions pertaining to the effects of personal characteristics on price sensitivity are not supported by the

    Fluctuations in prices of natural gas significantly affect global economy. Therefore, the research on the characteristics of natural gas price fluctuations, turning points and its influencing cycle on the subsequent price series is of great significance. Global natural gas trade concentrates on three regional markets: the North American market, the European market and the Asia-Pacific market, with North America having the most developed natural gas financial market. In addition, perfect legal supervision and coordinated regulations make the North American market more open and more competitive. This paper focuses on the North American natural gas market specifically. The Henry Hub natural gas spot price time series is converted to a visibility graph network which provides a new direction for macro analysis of time series, and several indicators are investigated: degree and degree distribution, the average shortest path length and community structure. The internal mechanisms underlying price fluctuations are explored through the indicators. The results show that the natural gas prices visibility graph network (NGP-VGN) is of small-world and scale-free properties simultaneously. After random rearrangement of original price time series, the degree distribution of network becomes exponential distribution, different from the original ones. This means that, the original price time series is of long-range negative correlation fractal characteristic. In addition, nodes with large degree correspond to significant geopolitical or economic events. Communities correspond to time cycles in visibility graph network. The cycles of time series and the impact scope of hubs can be found by community structure partition.

    A summary of the price evolution of liquefied petroleum gas (LPG) between 1979 and 1983 in Brazil is presented. The pricing policy adopted by the government as a tool for fighting inflation has caused problems to the LPG industry. It is proposed the implementation of a market policy in order to solve these problems

    1994-01-01

    This paper derives the optimal pricing policy for a firm facing menu costs and stochastic production cost. The pricing policy is a boundary pricing policy and numerical comparative static analysis shows how exogenous parameters - the drift and variance of the production cost, the discount factor and the menu costs - affect the boundaries. Analyzing daily data for the Danish petrol price illustrates that a boundary pricing policy indeed has been followed for the period 1988-1992, with occasional shifts in both the desired mark-up and more importantly in the width of the bounds. While the theoretical model can say nothing of the shifts in desired mark-up, changes in the width of the bounds are found to be consistent with the implications of the model. (au)

    1995-01-01

    The evolution of the price of natural gas (NG) is examined in industrial and tertiary residential sectors for European Union (EU) countries. The methodological approach is that of comparative analysis. NG price is seen to be positively correlated to prices of liquid fuels. NG price in the tertiary residential sector is significantly higher than that for the industrial sector for all countries examined. An attempt is undertaken to examine tax policies for NG and liquid fuels. All governments of EU countries have the policy of not applying direct taxes to the NG industrial price. They have also taken measures to support its penetration in the residential tertiary sector by applying lower taxes than those on liquid fuels. (author)

    We studied the market performance at selected, representative natural gas trading hubs in the U.S. and documented different price behaviors among various hubs. With NYMEX prices as the competitive benchmark, we found empirically that the spot price responses at some trading hubs were systematically asymmetric, thus demonstrating a market advantage by either buyers or sellers. We further found that the presence of market power was a very plausible explanation for this price behavior at some hubs. (author)

    Full Text Available BACKGROUND: Food pricing strategies have been proposed to encourage healthy eating habits, which may in turn help stem global increases in non-communicable diseases. This systematic review of simulation studies investigates the estimated association between food pricing strategies and changes in food purchases or intakes (consumption (objective 1; Health and disease outcomes (objective 2, and whether there are any differences in these outcomes by socio-economic group (objective 3. METHODS AND FINDINGS: Electronic databases, Internet search engines, and bibliographies of included studies were searched for articles published in English between 1 January 1990 and 24 October 2011 for countries in the Organisation for Economic Co-operation and Development. Where ≥ 3 studies examined the same pricing strategy and consumption (purchases or intake or health outcome, results were pooled, and a mean own-price elasticity (own-PE estimated (the own-PE represents the change in demand with a 1% change in price of that good. Objective 1: pooled estimates were possible for the following: (1 taxes on carbonated soft drinks: own-PE (n  =  4 studies, -0.93 (range, -0.06, -2.43, and a modelled -0.02% (-0.01%, -0.04% reduction in energy (calorie intake for each 1% price increase (n  =  3 studies; (2 taxes on saturated fat: -0.02% (-0.01%, -0.04% reduction in energy intake from saturated fat per 1% price increase (n  =  5 studies; and (3 subsidies on fruits and vegetables: own-PE (n = 3 studies, -0.35 (-0.21, -0.77. Objectives 2 and 3: variability of food pricing strategies and outcomes prevented pooled analyses, although higher quality studies suggested unintended compensatory purchasing that could result in overall effects being counter to health. Eleven of 14 studies evaluating lower socio-economic groups estimated that food pricing strategies would be associated with pro-health outcomes. Food pricing strategies also have the potential to reduce

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

  19. Energy prices and the post oil/energy crisis Brazilian inflation: an input-output study

    Energy Technology Data Exchange (ETDEWEB)

    Lara-Resende, M.deM.

    1982-01-01

    This study is an attempt to understand the implications of the OPEC-induced severalfold increase in the international price of oil for average and sectoral domestic prices in Brazil, a large oil-importing open developing economy. Rather than using a Keynesian model (focusing on the universal characteristics of an economy), the study makes use of an open-price input-output model (capturing the structural characteristics of the Brazilian economy). The first three chapters, descriptive in nature, place in perspective the following three, which detail the model and the empirical results. The main conclusion is that, despite the significant increase observed in the post-crisis period, the relative percentage contribution of primary energy to wholesale inflation in Brazil is still relatively minor. A conservative estimate suggests that, in the years of substantial acceleration (1974 and 1979), approximately 15% of the wholesale inflation was due to energy (basically crude oil and oil derivatives). Though such low estimates are partly due to the limitations and assumptions underlying input-output analysis, it seems that the acceleration of inflation is related to more than cost increases originating in energy prices. It also seems to be related to agricultural and labor prices, as well as to the government's decision to abruptly and inopportunely raise several important product prices.

    2001-01-01

    This paper provides an empirical analysis of the effects of weight-based pricing in the collection of household waste. Using a comprehensive panel data set on all households in a Dutch municipality we estimate short-run as well as long-run price effects for the amounts of both compostable and non-recyclable household waste. We find significant and sizeable price effects, with the elasticity for compostable waste being four times as large as the elasticity for non-recyclable waste. Long-run elasticities are about 30% larger than short-run elasticities

  2. Study of Volatility of New Ship Building Prices in LNG Shipping

    2016-12-01

    Full Text Available The natural gas market has been expanding in size and has attracted particular attention across the global energy market. Although most natural gas transportation is carried out through pipelines, almost one third of it is done with the help of merchant vessels, capable of carrying liquefied natural gas. These LNG carriers have a special design and thus can be treated as a separate class of global fleet. New vessels are huge capital investments by vessel owning companies and just like other vessel classes; the new shipbuilding prices for the LNG segment continue to be a key aspect in the decision making of business players. Additionally these prices can be volatile as new ship building prices fluctuate with time. This paper attempts to analyse the volatility of new ship building prices of LNG carriers. For the study, the average ship building prices for all the LNG carriers having volume carrying capacity is between 160,000 – 173,000 cbm to be delivered between 2016 – 2019 were taken into account. For the analysis, GARCH and EGARCH methods were applied on the data set. The analysis concluded that there is a great deal of volatility in the new ship building prices of LNG vessels. It was also identified that negative shocks were more persistent the positive shocks.

    2012-06-01

    Full Text Available This study presents an analysis of the relationship between different pricing policies and the results obtained with them within on Business Games. Beginning from a theoretical review that seeks to reunite concepts about pricing, policy and price definitions, it is proposed a model analysis of pricing decisions made by teams that participate in a Business Game. From the applying of this model on data collected in the game, it seeks to classify the pricing policies applied by the teams. Then the results are discussed and its relationship to literature is referred. There are also comments on the decision make default demonstrated by the teams participating in the game. The results obtained here confirm the literature, indicating the price policy as a helpful and valid tool to support marketing strategies. They also show the adhesion between the simulated environment in a Business Game and the features found in the real world, confirming the trend toward adoption of organizational strategy simulators as instruments in teaching and research in Administration.

  4. Renewable energy as a natural gas price hedge: the case of wind

    International Nuclear Information System (INIS)

    Berry, David

    2005-01-01

    Electric utilities use natural gas to fuel many of their power plants, especially those plants which provide electricity at peak and intermediate hours. Natural gas prices are highly volatile and have shown a general upward trend. Wind energy can provide a cost-effective hedge against natural gas price volatility or price increases. This conclusion is based on analysis of the costs of marginal conventional generation given the historical probability distribution of natural gas prices, the cost of wind energy, wind integration costs, transmission costs for wind energy, the capacity value of wind, and environmental benefits of wind energy for a hypothetical utility in the Southwestern United States. The efficacy of using wind energy as a hedge at a particular utility will depend on site specific conditions

    1999-01-01

    This research reviews the factors affecting the pricing or rate schedules of home health care agencies. A large number of factors affect costs and thus rate structures. The major factors include reimbursement structures with accompanying discount structures, administrative burdens, and risks. Channel issues include bargaining power, competition, and size. Staffing issues affect pricing and product through the provider level, productivity, and quality outcomes. Physician and patient issues include quality concerns and choices. These factors are discussed in light of overall marketing strategy and the interaction of pricing with other marketing controllables such as product, place/distribution, and promotion. Economic and accounting principles are also reviewed with consideration to understanding direct and indirect costs in order to enable negotiators to effectively price health care services.

  9. The case for indexed price caps for U.S. electric utilities

    International Nuclear Information System (INIS)

    Lowry, M.N.

    1991-01-01

    Indexed price caps are a promising alternative to traditional, cost-of-service utility rate regulation. In just a decade, they have sprung from the drawing boards of economists to use by major utilities in a number of industries. Several authors have discussed the merits of indexed price caps for U.S. electric utilities. Despite their efforts, many parties to electric utility policy making are unfamiliar with the subject. This is unsurprising given the policy controversies that already embroil the industry. It is also unfortunate, since indexed price caps may help solve some of the problems that prompt these controversies. Indexed price caps can improve electric utility rate regulation in two ways. Utilities would have strong incentives to improve performance without the micromanagement that increasingly characterizes state-level regulation. Utilities could also be granted more extensive marketing freedoms, since indexes can protect customers from cross-subsidization. Two areas of concern about indexed price cap plans have emerged in recent discussions that the author has held with officials of electric utilities, intervenor groups, and regulatory agencies. Officials are often unclear on plan details, and therefore may not appreciate the degree of flexibility that is possible in plan design. Confusion over the available options in price cap adjustment indexes and the logic behind them is especially widespread. Officials also desire a clearer expression of how indexed price caps can coexist with current regulatory initiatives. This article details the major attributes of index plans, provides a brief history of indexing, discusses index design options in depth, and concludes with a vision of how indexed price caps can be made operational in today's electric utility industry

    Prices for some generic drugs have increased in recent years, adversely affecting patients who rely on them. To determine the association between market competition levels and the change in generic drug prices in the United States. Retrospective cohort study. Prescription claims from commercial health plans between 2008 and 2013. The 5.5 years of data were divided into 11 study periods of 6 months each. The Herfindahl-Hirschman Index (HHI)-calculated by summing the squares of individual manufacturers' market shares, with higher values indicating a less competitive market-and average drug prices were estimated for the generic drugs in each period. The HHI value estimated in the baseline period (first half of 2008) was modeled as a fixed covariate. Models estimated price changes over time by level of competition, adjusting for drug shortages, market size, and dosage forms. From 1.08 billion prescription claims, a cohort of 1120 generic drugs was identified. After adjustment, drugs with quadropoly (HHI value of 2500, indicating relatively high levels of competition), duopoly (HHI value of 5000), near-monopoly (HHI value of 8000), and monopoly (HHI value of 10 000) levels of baseline competition were associated with price changes of -31.7% (95% CI, -34.4% to -28.9%), -11.8% (CI, -18.6% to -4.4%), 20.1% (CI, 5.5% to 36.6%), and 47.4% (CI, 25.4% to 73.2%), respectively, over the study period. Study findings may not be generalizable to drugs that became generic after 2008. Market competition levels were associated with a change in generic drug prices. Such measurements may be helpful in identifying older prescription drugs at higher risk for price change in the future. None.

  11. Pricing of temperature index insurance

    Directory of Open Access Journals (Sweden)

    Che Mohd Imran Che Taib

    2012-01-01

    Full Text Available The aim of this paper is to study pricing of weather insurance contracts based on temperature indices. Three different pricing methods are analysed: the classical burn approach, index modelling and temperature modelling. We take the data from Malaysia as our empirical case. Our results show that there is a significant difference between the burn and index pricing approaches on one hand, and the temperature modelling method on the other. The latter approach is pricing the insurance contract using a seasonal autoregressive time series model for daily temperature variations, and thus provides a precise probabilistic model for the fine structure of temperature evolution. We complement our pricing analysis by an investigation of the profit/loss distribution from the contract, in the perspective of both the insured and the insurer.

  12. Carbon prices and CCS investment: A comparative study between the European Union and China

    International Nuclear Information System (INIS)

    Renner, Marie

    2014-01-01

    Carbon Capture and Storage is considered as a key option for climate change mitigation; policy makers and investors need to know when CCS becomes economically attractive. Integrating CCS in a power plant adds significant costs which can be offset by a sufficient CO 2 price. However, most markets have failed: currently, the weak carbon price threatens CCS deployment in the European Union (EU). In China, a carbon regulation is appearing and CCS encounters a rising interest. This study investigates two questions: how much is the extra-cost of a CCS plant in the EU in comparison with China? Second, what is the CO 2 price beyond which CCS plants become more profitable than reference plants in the EU and in China? To address these issues, I conducted a literature review on public studies about CCS costs. To objectively assess the profitability of CCS plants, I constructed a net present value model to calculate the Levelised Cost of Electricity and the breakeven CO 2 price. CCS plants become the most profitable plant type beyond 115 €/tCO 2 in the EU vs. 45 €/tCO 2 in China (offshore transport and storage costs). I advise on the optimal plant type choice depending on the CO 2 price in both countries. - Highlights: • I develop a method to objectively update and compare CCS costs in the EU and China. • To represent investment choices, intra and inter CO 2 switching prices are required. • EU CCS plants are profitable for a CO 2 price higher than 115 €/t (offshore storage). • Chinese CCS plants are profitable beyond 45 €/tCO 2 (35 €/tCO 2 with onshore storage). • With 2030 projections, CCS (coal) plants are profitable in China but not in the EU

    In line with this, the U.S. has a renewed interest in SMRs rather than large reactors. Nothing, however, has been implemented yet. The only SMRs under construction are in Russia: the first floating nuclear plants. For the most part, the primary candidates to be the first land-based counterparts of Russia's are the SMART (System integrated Modular Advanced Reactor) reactors. The Korean SMART has been developed and licensed for standard design. In addition, the SMART reactor may be suited to countries, which have a small grid capacity, low population density, and decentralization power system such as the U.S. Therefore, the purpose of this paper is to develop a target price for the SMR market opportunities in the U.S., competing against the CCGT (Combined Cycle Gas Turbine) which is currently a very attractive option for generating due to the shale innovation. Even though detailed cost estimates are not available, target price can be derived based on generally determining market price. This paper demonstrates the target exporting price of the SMART in the U.S. ranging from 3,091 - 4,011$/kWe depending on the scaling factor and carbon tax, assuming that discount rates are fixed. This value could be a target cost of construction, developing the U.S market whose demand of the SMART is potentially 4 units 2015 - 2035. Sensitivity analysis shows that the price goes up in proportion to the gas price, the capacity factor of the SMART, the overnight cost of CCGT, etc. More than anything else, this study reveals that carbon tax does not have much influence on the target price compared with those listed above. On the other hand, the price goes up in inverse proportion to the interest of the SMART, the capacity factor of CCGT, O and M costs of the SMART, and so on. For the price competitiveness, construction cost should first be reduced because construction cost is the largest component of LCOE as well as the effect of interest rate is the most sensitive for target price

  20. Feed-in tariff and market electricity price comparison. The case of cogeneration units in Croatia

    International Nuclear Information System (INIS)

    Uran, Vedran; Krajcar, Slavko

    2009-01-01

    In August 2007, the Government of the Republic of Croatia instituted a feed-in tariff system, requiring the Croatian Electricity Market Operator (HROTE) to off-take the electricity produced from renewable energy sources or cogeneration units fueled by natural gas. Analysis of the off-take electricity price range, which depends on the net electrical output and electricity market trends, indicates that it is more cost effective for cogeneration units greater than 1 MW to sell their electricity on the exchange market. This was confirmed by developing a mathematical model to calculate the cost-effectiveness ratio of a cogeneration unit. This ratio represents the relation between the profit spread, i.e. the difference between the profit generated from selling the electricity on the exchange market and the profit made from dispatching the electricity to HROTE, as well as the total investment costs. The model can be applied for changes in certain parameters, such as the net electrical output, volatility and spot electricity price. The Monte Carlo method is used to obtain the most probable cost-effectiveness ratio and average future electricity price. Together with these two economic parameters and market price analysis, it is possible to calculate and calibrate an acceptable off-take electricity price. (author)

    The objective of this article is to estimate the cost of commercialization of the electricity generated from the acai seeds, under different commercial societies, namely agricultural cooperative, cooperative for rural electrification and independent producer of electricity. In the case of cooperative agriculture, the main products would be the acai pulp, among others, while the electricity would be a sub product resulting from the utilization of the residues from the process. For the other two arrangements, the electricity would be the main product, with differences in fees, taxes and financial structure between them. The taxes and fees associated with each one of the societies are considered for the estimates of energy costs. The results are presented as a variation of the electricity costs (Reais/MWh) over the load factor variation and are compared to the prices practiced for the bulk energy market for the independent producer in the Amazon region. All the results are presented with and without the subsidy for electricity. This study is part of the mark of the project {sup M}odel for Electric Power Enterprise in Isolated Communities in the Amazon - NERAM{sup ,} financed by the National Council for Scientific and Technological Development - CNPq, that contemplates the universal access to electric-power services and the idea of Integrated Planning of Resources (PIR) for isolated systems. The results appear for the need of subsidies and they present smaller costs for the sceneries that use the cooperatives, especially the cooperative of rural electrification. (author)

    Price boards in tobacco retailers are one of the few forms of tobacco promotion remaining in Australia. This study aimed to examine how these boards were used to promote products over a period of rapidly rising taxes. Observations were made in a panel of 350 stores in Melbourne, Australia, in November of 2013 (just before) and in 2014 and 2015 (after 12.5% increases in tobacco duty). Fieldworkers unobtrusively noted the presence and characteristics of price boards, and the brand name, size and price of the product at the top of each board. Price boards were common in all store types apart from newsagent/lottery agents. The characteristics of the top-listed product changed notably over time: premium brands accounted for 66% of top-listed products in 2013, significantly declining to 43% in 2015, while packs of 20 cigarettes increased in prominence from 32% to 45%. The prevalence of packs of 20 cigarettes in budget market segments tripled from 2013 (13%) and 2014 (11%) to 32% in 2015, with no change in the proportion of packs that were under $A20 from 2014 (37%) to 2015 (36%). The rate of increase in the average price of the top-listed pack correspondingly flattened from 2014 to 2015 compared with 2013-2014. Price boards promote tobacco products in ways that undermine the effectiveness of tax policy as a means of discouraging consumption. Communication to consumers about prices should be restricted to information sheets provided to adult smokers on request at the point of sale. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    This paper explores a method of managing the risk of the stock index futures market and the cross-market through analyzing the effectiveness of price limits on the Chinese Stock Index 300 futures market. We adopt a cross-market artificial financial market (include the stock market and the stock index futures market) as a platform on which to simulate the operation of the CSI 300 futures market by changing the settings of price limits. After comparing the market stability under different price limits by appropriate liquidity and volatility indicators, we find that enhancing price limits or removing price limits both play a negative impact on market stability. In contrast, a positive impact exists on market stability if the existing price limit is maintained (increase of limit by10%, down by 10%) or it is broadened to a proper extent. Our study provides reasonable advice for a price limit setting and risk management for CSI 300 futures.

    Objective To investigate longitudinal associations between community-level gasoline price and physical activity (PA). Method In the Coronary Artery Risk Development in Young Adults study, 5,115 black and white participants aged 18–30 at baseline 1985–86 were recruited from four U.S. cities (Birmingham, Chicago, Minneapolis and Oakland) and followed over time. We used data from 3 follow-up exams: 1992–93, 1995–96, and 2000–01, when the participants were located across 48 states. From questionnaire data, a total PA score was summarized in exercise units (EU) based on intensity and frequency of 13 PA categories. Using Geographic Information Systems, participants’ residential locations were linked to county-level inflation-adjusted gasoline price data collected by the Council for Community & Economic Research. We used a random-effect longitudinal regression model to examine associations between time-varying gasoline price and time-varying PA, controlling for age, race, gender, baseline study center, and time-varying education, marital status, household income, county cost of living, county bus fare, census block-group poverty, and urbanicity. Results Holding all control variables constant, a 25-cent increase in inflation-adjusted gasoline price was significantly associated with an increase of 9.9 EU in total PA (95%CI: 0.8–19.1). Conclusion Rising prices of gasoline may be associated with an unintended increase in leisure PA. PMID:21338621

  6. Optimization of a Future RLV Business Case using Multiple Strategic Market Prices

    There is a lack of depth in the current paradigm of conceptual level economic models used to evaluate the value and viability of future capital projects such as a commercial reusable launch vehicle (RLV). Current modeling methods assume a single price is charged to all customers, public or private, in order to optimize the economic metrics of interest. This assumption may not be valid given the different utility functions for space services of public and private entities. The government's requirements are generally more inflexible than its commercial counterparts. A government's launch schedules are much more rigid, choices of international launch services restricted, and launch specifications generally more stringent as well as numerous. These requirements generally make the government's demand curve more inelastic. Subsequently, a launch vehicle provider will charge a higher price (launch price per kg) to the government and may obtain a higher level of financial profit compared to an equivalent a commercial payload. This profit is not a sufficient condition to enable RLV development by itself but can help in making the financial situation slightly better. An RLV can potentially address multiple payload markets; each market has a different price elasticity of demand for both the commercial and government customer. Thus, a more resilient examination of the economic landscape requires optimization of multiple prices in which each price affects a different demand curve. Such an examination is performed here using the Cost and Business Analysis Module (CABAM), an MS-Excel spreadsheet-based model that attempts to couple both the demand and supply for space transportation services in the future. The demand takes the form of market assumptions (both near-term and far-term) and the supply comes from user-defined vehicles that are placed into the model. CABAM represents RLV projects as commercial endeavors with the possibility to model the effects of government

    Differential pricing, based on countries' purchasing power, is recommended by the World Health Organization to secure affordable medicines. However, in developing countries innovative drugs often have similar or even higher prices than in high-income countries. We evaluated the potential implications of trastuzumab global pricing policies in terms of cost-effectiveness (CE), coverage, and accessibility for patients with breast cancer in Latin America (LA). A Markov model was designed to estimate life-years (LYs), quality-adjusted life-years (QALYs), and costs from a healthcare perspective. To better fit local cancer prognosis, a base case scenario using transition probabilities from clinical trials was complemented with two alternative scenarios with transition probabilities adjusted to reflect breast cancer epidemiology in each country. Incremental discounted benefits ranged from 0.87 to 1.00 LY and 0.51 to 0.60 QALY and incremental CE ratios from USD 42,104 to USD 110,283 per QALY (2012 U.S. dollars), equivalent to 3.6 gross domestic product per capita (GDPPC) per QALY in Uruguay and to 35.5 GDPPC in Bolivia. Probabilistic sensitivity analysis showed 0 percent probability that trastuzumab is CE if the willingness-to-pay threshold is one GDPPC per QALY, and remained so at three GDPPC threshold except for Chile and Uruguay (4.3 percent and 26.6 percent, respectively). Trastuzumab price would need to decrease between 69.6 percent to 94.9 percent to became CE in LA. Although CE in other settings, trastuzumab was not CE in LA. The use of health technology assessment to prioritize resource allocation and support price negotiations is critical to making innovative drugs available and affordable in developing countries.

  11. Would environmental pollution affect home prices? An empirical study based on China's key cities.

    With the development of China's economy, the problem of environmental pollution has become increasingly more serious, affecting the sustained and healthy development of Chinese cities and the willingness of residents to invest in fixed assets. In this paper, a panel data set of 70 of China's key cities from 2003 to 2014 is used to study the effect of environmental pollution on home prices in China's key cities. In addition to the static panel data regression model, this paper uses the generalized method of moments (GMM) to control for the potential endogeneity and introduce the dynamics. To ensure the robustness of the research results, this paper uses four typical pollutants: per capita volume of SO 2 emissions, industrial soot (dust) emissions, industrial wastewater discharge, and industrial chemical oxygen demand discharge. The analysis shows that environmental pollution does have a negative impact on home prices, and the magnitude of this effect is dependent on the level of economic development. When GDP per capita increases, the size of the negative impact on home prices tends to reduce. Industrial soot (dust) has the greatest impact, and the impact of industrial wastewater is relatively small. It is also found that some other social and economic factors, including greening, public transport, citizen income, fiscal situation, loans, FDI, and population density, have positive effects on home prices, but the effect of employment on home prices is relatively weak.

    OBJECTIVES: This study examined the effects of pricing and promotion strategies on purchases of low-fat snacks from vending machines. METHODS: Low-fat snacks were added to 55 vending machines in a convenience sample of 12 secondary schools and 12 worksites. Four pricing levels (equal price, 10% reduction, 25% reduction, 50% reduction) and 3 promotional conditions (none, low-fat label, low-fat label plus promotional sign) were crossed in a Latin square design. Sales of low-fat vending snacks were measured continuously for the 12-month intervention. RESULTS: Price reductions of 10%, 25%, and 50% on low-fat snacks were associated with significant increases in low-fat snack sales; percentages of low-fat snack sales increased by 9%, 39%, and 93%, respectively. Promotional signage was independently but weakly associated with increases in low-fat snack sales. Average profits per machine were not affected by the vending interventions. CONCLUSIONS: Reducing relative prices on low-fat snacks was effective in promoting lower-fat snack purchases from vending machines in both adult and adolescent populations. PMID:11189801

  14. An illustrative note on the system price effect of wind and solar power. The German case

    Jaegemann, Cosima

    2014-01-01

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV el ) of renewable energy technologies. As shown by Lamont (2008), the MV el of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MV el (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours. This so called 'system price effect' is analyzed in more detail in this paper. The analysis complements the work Lamont (2008) in two regards. First of all, an alternative expression for the MV el of wind and solar power units is derived, which shows that the MV el of fluctuating renewable energy technologies depends not only on their own penetration level but also on a variety of other parameters that are specific to the electricity system. Second, based on historical wholesale prices and wind and solar power generation data for Germany, a numerical 'ceteris paribus' example for Germany is presented which illustrates that the system price effect is already highly relevant for both wind and solar power generation in Germany.

    Highlights: ► An existing bottom-up deterministic energy system model (ESM) has limited capability in handling the uncertainties. ► Uncertainty has been modeled based on GBM. Probabilistic scenarios are generated based on Cox–Ross method. ► A multistage stochastic model has been developed where scenarios are integrated in the energy system model. ► A distributed generation system has been introduced as a case study where fuel price is considered as an uncertain parameter. - Abstract: A deterministic energy supply model with bottom-up structure has limited capability in handling the uncertainties. To enhance the applicability of such a model in an uncertain environment two main issues have been investigated in the present paper. First, a binomial lattice is generated based on the stochastic nature of the source of uncertainty. Second, an energy system model (ESM) has been reformulated as a multistage stochastic problem. The result of the application of the modified energy model encompasses all uncertain outcomes together and enables optimal timing of capacity expansion. The performance of the model has been demonstrated with the help of a case study. The case study has been formulated on the assumption that a gas fired engine competes with renewable energy technologies in an uncertain environment where the price of natural gas is volatile. The result of stochastic model has then been compared with those of a deterministic model by studying the expected value of perfect information (EVPI) and the value of stochastic solution (VSS). Finally the results of the sensitivity analysis have been discussed where the characteristics of uncertainty of the price of fuel are varied.

    Gori, F.

    2006-01-01

    The time evolution of the price of resources sold to the market and of the price difference, between sold and extracted resources, is investigated in case of no accumulation of the resources; i.e. when the resources are extracted and sold to the market at the same mass flow rate. The price evolution of sold resources varies with time according to the relation between the price increase factor, PIF, of sold and extracted resources. The price evolutions of sold resources and price difference are investigated according to the relation between extraction rate and interest rate of extracted and sold resources. The price of sold resources and the price difference increase with time if the PIF of sold resources is greater than the PIF of extracted resources and the initial price is greater than the critical price of sold resources, which depends on the initial price of extracted resources and the interest rate of non-extracted and extracted resources. The price of sold resources and the price difference decrease with time if the PIF of sold resources is greater than the PIF of extracted resources and the initial price is smaller than the critical price of sold resources. The other cases are discussed extensively in the paper. (author)

  19. The impact on health outcomes and healthcare utilisation of switching to generic medicines consequent to reference pricing: the case of lamotrigine in New Zealand.

    2014-10-01

    Many countries have implemented generic reference pricing and substitution as methods of containing pharmaceutical expenditure. However, resistance to switching between medicines is apparent, especially in the case of anti-epileptic medicines. This study sought to exploit a nation-wide policy intervention on generic reference pricing in New Zealand to evaluate the health outcomes of patients switching from originator to generic lamotrigine, an anti-epileptic medicine. A retrospective study using the national health collections and prescription records was conducted comparing patients who switched from originator brand to generic lamotrigine with patients who remained on the originator brand. Primary outcome measures included switch behaviour, changes in utilisation of healthcare services at emergency departments, hospitalisations and use of specialist services, and mortality. Approximately one-quarter of all patients using the originator brand of lamotrigine switched to generic lamotrigine, half of whom made the switch within 60 days of the policy implementation. Multiple switches (three or more) between generic and brand products were evident for around 10% of switchers. Switch-back rates of 3% were apparent within 30 days post-switch. No difference in heath outcome measures was associated with switching from originator lamotrigine to a generic equivalent and hence no increased costs could be found for switchers. Switching from brand to generic lamotrigine is largely devoid of adverse health outcomes; however, creating an incentive to ensure a greater proportion of patients switch to generic lamotrigine is required to achieve maximal financial savings from a policy of generic reference pricing.

This study aimed to explore the characteristics of tobacco displays in a UK city, and particularly to assess the tobacco prices and promotional offers, types and pack sizes on display.Digital pictures of PoS displays were taken in 117 small retail shops in Nottingham in mid 2010. Data were analysed using Windows Photo Gallery software and SPSS version 16.Just over half (52% of cigarette packs on display were packs of 20, and 43% packs of 10. Cigarette prices differed substantially between brands, ranging from £4.19 to £6.85 for 20-packs, and from £2.12 to £3.59 for 10-packs. Forty four percent of cigarette packs and 40% of RYO (Roll-Your-Own tobacco pouches, almost exclusively lower priced brands, were displayed with a pricemark, implying a promotional price offer. Eighty percent of 20-pack cigarette brand or brand variants on sale were priced below the EU-defined Most Popular Price Category (MPPC for the UK in 2010; 45% were priced below the Weighted Average Price (WAP, which replaced the MPPC in 2011.PoS displays communicate value by displaying a high proportion of lower cost brands, and smaller and hence lower-cost packs, and by displaying price discounts on packs. The MPPC substantially overestimated the prices at which most 20-cigarette packs were available. Removal of PoS displays will prevent this means of price marketing but our study also suggests that minimum pricing of 20-pack cigarettes, prohibition of sale of cigarettes in packs less than 20, and plain packaging to prevent pricemarking are necessary if price is to be used effectively as a tobacco control measure.

Removal of PoS displays will prevent this means of price marketing but our study also suggests that minimum pricing of 20-pack cigarettes, prohibition of sale of cigarettes in packs less than 20, and plain packaging to prevent pricemarking are necessary if price is to be used effectively as a tobacco control measure.

    Evidence supports the use of pricing interventions in achieving healthier behaviour at population level. The public acceptability of this strategy continues to be debated throughout Europe, Australasia and USA. We examined public attitudes towards, and beliefs about the acceptability of pricing policies to change health-related behaviours in the UK. The study explores what underlies ideas of acceptability, and in particular those values and beliefs that potentially compete with the evidence presented by policy-makers. Twelve focus group discussions were held in the London area using a common protocol with visual and textual stimuli. Over 300,000 words of verbatim transcript were inductively coded and analyzed, and themes extracted using a constant comparative method. Attitudes towards pricing policies to change three behaviours (smoking, and excessive consumption of alcohol and food) to improve health outcomes, were unfavourable and acceptability was low. Three sets of beliefs appeared to underpin these attitudes: (i) pricing makes no difference to behaviour; (ii) government raises prices to generate income, not to achieve healthier behaviour and (iii) government is not trustworthy. These beliefs were evident in discussions of all types of health-related behaviour. The low acceptability of pricing interventions to achieve healthier behaviours in populations was linked among these responders to a set of beliefs indicating low trust in government. Acceptability might be increased if evidence regarding effectiveness came from trusted sources seen as independent of government and was supported by public involvement and hypothecated taxation. © The Author 2015.

  10. Energy consumption, prices and economic growth in three SSA countries: A comparative study

    International Nuclear Information System (INIS)

    Odhiambo, Nicholas M.

    2010-01-01

    In this paper we examine the causal relationship between energy consumption and economic growth in three sub-Saharan African countries, namely South Africa, Kenya and Congo (DRC). We incorporate prices as an intermittent variable in a bivariate setting between energy consumption and economic growth-thereby creating a simple trivariate framework. Using the ARDL-bounds testing procedure, we find that the causality between energy consumption and economic growth varies significantly across the countries under study. The results show that for South Africa and Kenya there is a unidirectional causal flow from energy consumption to economic growth. However, for Congo (DRC) it is economic growth that drives energy consumption. These findings have important policy implications insofar as energy conservation policies are concerned. In the case of Congo (DRC), for example, the implementation of energy conservation policies may not significantly affect economic growth because the country's economy is not entirely energy dependent. However, for South Africa and Kenya there is a need for more energy supply augmentations in order to cope with the long-run energy demand. In the short-run, however, the two countries should explore more efficient and cost-effective sources of energy in order to address the energy dependency problem.

    The economic and social impact of the energy policy and pricing in countries with economies in transition is shown on the Polish example. Detailed changes in industrial production, growth of investments in Poland are shown for the period 1990-1996 with annual inflation rate unemployment data. This is followed by expected growth of investments and inflation for the period 1993-2000. In the framework of primary energy consumption structure in 1994 and prospect for 2000 two possible scenarios of gas consumption by households, industry and for power generation, are presented up to 2010. Gas prices for the mentioned consumers in Poland are compared to those in Western Europe and environmental impacts are mentioned as well

  13. The Retail Chain Design for Perishable Food: The Case of Price Strategy and Shelf Space Allocation

    2016-12-01

    Full Text Available Managing perishable food in a retail store is quite difficult because of the product’s short lifetime and deterioration. Many elements, such as price, shelf space allocation, and quality, which can affect the consumption rate, should be taken into account when the perishable food retail chain is designed. The modern tracking technologies provide good opportunities to improve the management of the perishable food retail chain. In this research, we develop a mathematical model for a single-item retail chain and determine the pricing strategy, shelf space allocation, and order quantity to maximize the retailer’s total profit with the application of tracking technologies. Then the single-item retail chain is extended into a multi-item one with a shelf space capacity and a simple algorithm is developed to find the optimal allocation of shelf space among these items. Finally, numerical experiments and real-life examples are conducted to illustrate the proposed models.

  15. An illustrative note on the system price effect of wind and solar power. The German case

    Energy Technology Data Exchange (ETDEWEB)

    Jaegemann, Cosima

    2014-07-15

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV{sup el}) of renewable energy technologies. As shown by Lamont (2008), the MV{sup el} of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MV{sup el} (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours. This so called 'system price effect' is analyzed in more detail in this paper. The analysis complements the work Lamont (2008) in two regards. First of all, an alternative expression for the MV{sup el} of wind and solar power units is derived, which shows that the MV{sup el} of fluctuating renewable energy technologies depends not only on their own penetration level but also on a variety of other parameters that are specific to the electricity system. Second, based on historical wholesale prices and wind and solar power generation data for Germany, a numerical 'ceteris paribus' example for Germany is presented which illustrates that the system price effect is already highly relevant for both wind and solar power generation in Germany.

    This paper looks into various models that address strategic behavior in the supply of gas by the Mexican monopoly Pemex. The paper has three very strong technical results. First, the netback pricing rule for the price of domestic natural gas (based on a Houston benchmark price) leads to discontinuities in Pemex's revenue function. Second, having Pemex pay for the gas it uses and the gas it flares increases the value of the Lagrange multiplier associated with the gas processing constraint. Third, if the gas processing constraint is binding, having Pemex pay for the gas it uses and flares does not change the short run optimal solution for the optimization problem, so it will have no impact on short-run behavior. These results imply three clear policy recommendations. The first is that the arbitrage point be fixed by the amount of gas Pemex has the potential to supply in the absence of processing and gathering constraints. The second is that Pemex be charged for the gas it uses in production and the gas it flares. The third is that investment in gas processing and pipeline should be in a separate account from other Pemex investment. (orig.)

    To explore the impact of price manipulation and healthy eating information on intended food choices. Health information was provided to a random half of subjects (vs. information on Saudi agriculture). Each subject chose from the same lunch menu, containing two healthy and two unhealthy entrees, deserts and beverages, on five occasions. Reference case prices were 5, 3 and 2 Saudi Arabian Reals (SARs). Prices of healthy and unhealthy items were manipulated up (taxed) and down (subsidized) by 1 SAR in four menu variations (random order); subjects were given a budget enabling full choice within any menu. The number of healthy food choices were compared with different price combinations, and between information groups. Linear regression modelling explored the effect of relative prices of healthy/unhealthy options and information on number of healthy choices controlling for dietary behaviours and hunger levels. University campus, Saudi Arabia, 2013. 99 women students. In the reference case, 49.5% of choices were for healthy items. When the price of healthy items was reduced, 58.5% of selections were healthy; 57.2% when the price of unhealthy items rose. In regression modelling, reducing the price of healthy items and increasing the price of unhealthy items increased the number of healthy choices by 5% and 6% respectively. Students reporting a less healthy usual diet selected significantly fewer healthy items. Providing healthy eating information was not a significant influence. Price manipulation offers potential for altering behaviours to combat rising youth obesity in Saudi Arabia. Copyright © 2018 Elsevier Ltd. All rights reserved.

  20. Exporter Price Premia?

    Jäkel, Ina Charlotte; Sørensen, Allan

    This paper provides new evidence on manufacturing firms' output prices: in Denmark, on average, exported varieties are sold at a lower price (i.e. a negative exporter price premium) relative to only domestically sold varieties. This finding stands in sharp contrast to previous studies, which have...... found positive exporter price premia. We also document that the exporter price premium varies substantially across products (both in terms of sign and magnitude). We show that in a standard heterogeneous firms model with heterogeneity in quality as well as production efficiency there is indeed no clear......-cut prediction on the sign of the exporter price premium. However, the model unambiguously predicts a negative exporter price premium in terms of quality-adjusted prices, i.e. prices per unit of quality. This prediction is broadly borne out in the Danish data: while the magnitude of the premium varies across...

    Full Text Available Being a new research area, logistics finance solves the contradiction between banks and SMEs (small and medium enterprises about financing; it is beneficial to financial market and logistics market development too. As a service innovation, it unites the interests of bank, 3PL (third-party logistics providers, and SMEs and integrates material, finance, and information. Logistics finance has been developed in recent years in China, but the research is not enough on 3PL enterprises. On the background of that, the paper makes a research in the field of logistics finance with different pricing methods, based on the perspective of third-party logistics enterprises. This paper proposes a pricing model of inventory financing that can maximize the cash flow of 3PL enterprise, when the default rate of the small- and medium-sized enterprise is affected by the pledge price. And then this paper studies the model of inventory financing that can maximize the cash flow of enterprise under the condition of the existence of cash discount rate. The core factors affecting the loan-to-value ratio were established through analysis of mathematical model. We also consider the loan-to-value ratio of cash discount rate in the model. Results show that in the pledge of the known function and cash discount the price change can be calculated to meet enterprise cash flow lending rates and get biggest loan-to-value ratio.

    2010-01-01

    This study examines the co-movements and information transmission among the spot prices of four precious metals (gold, silver, platinum, and palladium), oil price, and the US dollar/euro exchange rate. We find evidence of a weak long-run equilibrium relationship but strong feedbacks in the short run. The spot precious metal markets respond significantly (but temporarily) to a shock in any of the prices of the other metal prices and the exchange rate. Furthermore, we discover some evidence of market overreactions in the palladium and platinum cases as well as in the exchange rate market. In conclusion, whether there are overreactions and re-adjustments or not, investors may diversify at least a portion of the risk away by investing in precious metals, oil, and the euro. Policy implications are provided. (author)

    Full Text Available In this study, it has been attempted to select the best continuous- time stochastic model, in order to describe and forecast the oil price of Russia, by information and statistics about oil price that has been available for oil price in the past. For this purpose, method of The Maximum Likelihood Estimation is implemented for estimation of the parameters of continuous-time stochastic processes. The result of unit root test with a structural break, reveals that time series of the crude oil price is a stationary series. The simulation of continuous-time stochastic processes and the mean square error between the simulated prices and the market ones shows that the Geometric Brownian Motion is the best model for the Russian crude oil price.

    The transport and storage activities of British Gas company are controlled by a distinct organization named Transco. The access charges paid by the suppliers for the use of Transco's network are regulated by a price cap since October 1, 1994. However, Ofgas, the office of gas supply which is the regulation authority in charge of the control of competition and of British Gas activities, considers this control system as inefficient and has chosen a RPI (retail price index)-X (expected productivity factor)-type price cap for the control of gas transport tariffs. This has led to a disagreement between Transco and Ofgas which has delayed the implementation of the new system up to February 1998. This article compares the choices made by Ofgas for the control of gas transport tariffs with the economical theory. It recalls first, the reasons why the price cap appears as more efficient than the service cost regulation, the alternate method used by regulation authorities to control the tariffs of natural monopolies. Then, the difficulties linked with the implementation of the price cap for the transport of natural gas in the UK are analyzed in order to explain the reasons that led Ofgas to change its formula. Finally, the bases of an optimum hybrid formula are proposed. (J.S.)

    2013-01-01

    Full Text Available Focusing on the first-best marginal cost pricing (MCP in a stochastic network with both travel demand uncertainty and stochastic perception errors within the travelers’ route choice decision processes, this paper develops a perceived risk-based stochastic network marginal cost pricing (PRSN-MCP model. Numerical examples based on an integrated method combining the moment analysis approach, the fitting distribution method, and the reliability measures are also provided to demonstrate the importance and properties of the proposed model. The main finding is that ignoring the effect of travel time reliability and travelers’ perception errors may significantly reduce the performance of the first-best MCP tolls, especially under high travelers’ confidence and network congestion levels. The analysis result could also enhance our understanding of (1 the effect of stochastic perception error (SPE on the perceived travel time distribution and the components of road toll; (2 the effect of road toll on the actual travel time distribution and its reliability measures; (3 the effect of road toll on the total network travel time distribution and its statistics; and (4 the effect of travel demand level and the value of reliability (VoR level on the components of road toll.

Still, it is not known how these consumers perceive pricing strategies, which pricing strategies are favoured and what contextual factors are important in achieving the anticipated effects. Methods We conducted seven focus groups among 59 residents of deprived neighbourhoods in two large Dutch cities. The focus group topics were based on insights from Rogers' Diffusion of Innovations Theory and consisted of four parts: 1 discussion on factors in food selection; 2 attitudes and perceptions towards food prices; 3 thinking up pricing strategies; 4 attitudes and perceptions regarding nine pricing strategies that were nominated by experts in a former Delphi Study. Analyses were conducted with Atlas.ti 5.2 computer software, using the framework approach. Results Qualitative analyses revealed that this group of consumers consider price to be a core factor in food choice and that they experience financial barriers against buying certain foods. Price was also experienced as a proficient tool to stimulate healthier food choices. Yet, consumers indicated that significant effects could only be achieved by combining price with information and promotion techniques. In general, pricing strategies focusing on encouraging healthy eating were valued to be more helpful than pricing strategies which focused on discouraging unhealthy eating. Suggested high reward strategies were: reducing the price of healthier options of comparable products (e.g., whole meal bread compared to unhealthier options (e.g., white bread; providing a healthy food discount card for low-income groups; and combining price discounts on healthier foods with other marketing techniques such as displaying cheap and healthy foods at the cash desk.

    This study develops an international hedging model which accounts for the multiple risks of input and output prices and exchange rates. Considering a fixed production technology, we formulize simultaneous minimum variance hedge ratios, which reflects inter correlations among prices. To utilize the dynamic nature of prices, time-varying conditional procedures are specified to estimate the relevant variance and covariance matrix. The time-varying representations of the variance and covariance matrix are statistically appropriate, in general. The separate hedge ratios are similar to the simultaneous hedge ratios for alternative procedures. The ex post hedging effectiveness indicate that there are substantial reduction in the variance of returns for all the procedures. The contribution of foreign currency futures is minimal due to the low correlation between commodities and exchange rates. Based on the traditional definition of hedging effectiveness, the time-varying conditional procedure provide little gain to the hedgers over a constant procedure in terms of the mean and the variance reduction. However, the performance of conditional procedures could be improved by accounting for the potential problems: mis specification problem, inappropriate definition of hedging effectiveness, and conflicts between theoretical derivation and estimation of hedge ratios.

    BACKGROUND: High out-of-pocket drug expenditures are increasingly common in dermatology. Patients may not be aware that prices vary among pharmacies and consequently may not shop for the lowest cost. OBJECTIVE: To determine what factors influence pharmacy choice and the effect of providing local prescription prices on pharmacy selection. We hypothesized that patients do not "shop around" due to lack of knowledge of price variation and would choose a pharmacy based on costs if educated on price disparity. METHODS: Between July and August 2016, we administered a cross-sectional anonymous survey to adults visiting four outpatient clinics at an academic tertiary care center in Washington, D.C. Participants answered questions before and after viewing a list of prescription drug prices from local pharmacies. RESULTS: 287 surveys were administered to a convenience sample of adults (age ≥ 18 and literate in English). Of the 287 participants, 218 fully completed the survey; 55.1% were women and 40.5% were over age 40. When considering a cost savings of $10-25, 65% would switch pharmacies if the distance were the same, and 21.3% would switch if the distance were 45-minutes further. After price education, fewer participants felt that drug price knowledge would ultimately influence pharmacy choice (P less than 0.0001). However, respondents' intended frequency of researching price online, calling a pharmacy to ask about price, and comparing price between pharmacies before filling a prescription all increased, compared to prior self-reported frequencies (P less than 0.001). Specifically, participants with $75,000-$99,999 income were more likely to compare prices than those with income below $45,000 (odds ratio [OR], 4.62; 95% confidence interval [CI], 1.24-17.28). CONCLUSION: In this study, pharmacy choice was more influenced by convenience than cost prior to drug price education. However, price education ultimately impacted intent to research prescription drug prices before

    Full Text Available In year 2008, regulation of Indonesian telecommunicationindustries changes due the tariff pricing war within Telecommunication opera-tor. This regulation tie up the telecommunication operator and affect operating revenue margin.The needs of financial flexibility within tele-communication firm is increased.Capex, operating revenue and reinvestment needs to be flexible must be inline with competition and change of technology. This paper goals is measuring financial flexibility based on Capex, operating revenue and re-investment needs.Reinvestment needs by Telecommunication operator can be financed with or without financial flexibility. Data from year 2007 up to 2014 is selec-ted to accommodate before and after changes of telecommunication regulation. The regulation effect to financial flexibility of telecommu-nication firm is still relevantbecause telecommunication industries by nature needs larger capital to re-new the telecommunication technology. Real options method will be used to measure financial flexibility.

  1. Pricing hospital care: Global budgets and marginal pricing strategies.

    2015-08-01

    The Canadian province of British Columbia (BC) is adding financial incentives to increase the volume of surgeries provided by hospitals using a marginal pricing approach. The objective of this study is to calculate marginal costs of surgeries based on assumptions regarding hospitals' availability of labor and equipment. This study is based on observational clinical, administrative and financial data generated by hospitals. Hospital inpatient and outpatient discharge summaries from the province are linked with detailed activity-based costing information, stratified by assigned case mix categorizations. To reflect a range of operating constraints governing hospitals' ability to increase their volume of surgeries, a number of scenarios are proposed. Under these scenarios, estimated marginal costs are calculated and compared to prices being offered as incentives to hospitals. Existing data can be used to support alternative strategies for pricing hospital care. Prices for inpatient surgeries do not generate positive margins under a range of operating scenarios. Hip and knee surgeries generate surpluses for hospitals even under the most costly labor conditions and are expected to generate additional volume. In health systems that wish to fine-tune financial incentives, setting prices that create incentives for additional volume should reflect knowledge of hospitals' underlying cost structures. Possible implications of mis-pricing include no response to the incentives or uneven increases in supply. Copyright © 2015 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    Reference price systems for prescription drugs have found widespread use as cost containment tools. Under such regulatory regimes, patients co-pay a fraction of the difference between pharmacy retail price of the drug and a reference price. Reference prices are either externally (based on drug...... prices in other countries) or internally (based on domestic drug prices) determined. In a recent study, we analysed the effects of a change from external to internal reference pricing in Denmark in 2005, finding that the reform led to substantial reductions in prices, producer revenues, and expenditures...... for patients and the health insurance system. We also estimated an increase in consumer welfare but the size effect depends on whether or not perceived quality differences between branded and other drugs are taken into account....

    Full Text Available The present study tries to apply the “Partial Adjustment Model” and “Random Effect Model” techniques to the Stone-Greay’s linear expenditure system, in order to estimate the "Residential Seasonal Demand" for water in Arak city. Per capita water consumption of family residences is regressed on marginal price, per capita income, price of other goods, average temperature and average rainfall. Panel data approaches based on a sample of 152 observations from Arak city referred to 1993-2003. From the estimation of the Elasticity-price of the residential water demand, we want to know how a policy of responsive pricing can lead to more efficient household water consumption inArakcity. Results also indicated that summer price elasticity was twice the winter and price and income elasticity was less than 1 in all cases.

  4. Perpetual American vanilla option pricing under single regime change risk: an exhaustive study

    2009-07-01

    Perpetual American options are financial instruments that can be readily exercised and do not mature. In this paper we study in detail the problem of pricing this kind of derivatives, for the most popular flavour, within a framework in which some of the properties—volatility and dividend policy—of the underlying stock can change at a random instant of time but in such a way that we can forecast their final values. Under this assumption we can model actual market conditions because most relevant facts usually entail sharp predictable consequences. The effect of this potential risk on perpetual American vanilla options is remarkable: the very equation that will determine the fair price depends on the solution to be found. Sound results are found under the optics both of finance and physics. In particular, a parallelism among the overall outcome of this problem and a phase transition is established.

    The authors define the notions of use values and price of plutonium. They give a 'simplified parametrized model' simulating the equilibrium of the offer and the demand in time, concerning the plutonium and the price deriving from the relative scarcity of this metal, taking into account the technical and economic operating parameters of the various reactors confronted. This model is simple enough to allow direct computations and establish clear relations between the various parameters. The use of the linear programmes method allows on the other hand a wide extension of the model. This report includes three main parts: I - General description of the study (without detailed calculations) II - Mathematical development of the simplified parametrized model and application (the basic data and the results of the calculations are given) III - Appendices (giving the detailed computations of part II).

  6. A field study using an adaptive in-house pricing model for commercial and industrial customers in Korea

    Demand response programs provide customers with economic incentives for load reductions at times of high market prices and system reliability constraints. One type of demand response programs, price-based program, induces customers to respond to changes in product rates. However, some large-scale customers find it difficult to change their electricity consumption patterns, even with rate changes, because their electricity demands are commercial and industrial. This study proposes an adaptive in-house pricing model for large-scale customers, particularly those with multiple business facilities, for self-regulating price-based program. The adaptive in-house pricing model charges higher rates to customers with lower load factors by employing a peak-to-off-peak usage ratio in order to reduce usage at times of high prices at each facility. This study analyzes the daily electricity consumption patterns of large-scale customers through a field trial of the proposed pricing model at a telecom company with 447 offices and worksites for one month. The results show that the pricing model corresponds to average reductions of 3.54–28.69% during peak-demand times for four different types of workplaces. However, reductions in electricity consumption during off-peak periods did not show a significant difference. The results of this study prove that this proposed pricing model can be successfully applied to large-scale operations. - Highlights: • The pricing model induces reductions in energy consumption during peak-demand times. • The greatest decrease occurs in commercial buildings with higher POR. • Data centers with flat loads for necessities can do little to reduce usage.

  7. Oil prices. Brownian motion or mean reversion? A study using a one year ahead density forecast criterion

    International Nuclear Information System (INIS)

    Meade, Nigel

    2010-01-01

    For oil related investment appraisal, an accurate description of the evolving uncertainty in the oil price is essential. For example, when using real option theory to value an investment, a density function for the future price of oil is central to the option valuation. The literature on oil pricing offers two views. The arbitrage pricing theory literature for oil suggests geometric Brownian motion and mean reversion models. Empirically driven literature suggests ARMA-GARCH models. In addition to reflecting the volatility of the market, the density function of future prices should also incorporate the uncertainty due to price jumps, a common occurrence in the oil market. In this study, the accuracy of density forecasts for up to a year ahead is the major criterion for a comparison of a range of models of oil price behaviour, both those proposed in the literature and following from data analysis. The Kullbach Leibler information criterion is used to measure the accuracy of density forecasts. Using two crude oil price series, Brent and West Texas Intermediate (WTI) representing the US market, we demonstrate that accurate density forecasts are achievable for up to nearly two years ahead using a mixture of two Gaussians innovation processes with GARCH and no mean reversion.

  10. Energy prices and the promotion of energy conservation. A background study for energy conservation programme

    International Nuclear Information System (INIS)

    1994-01-01

    The prices of fuels in the international markets affect the development of consumer prices of energy in Finland. In the near future no factors can be foreseen, which would cause major increases in the prices of oil, coal or gas. It can thus not be expected that increased fuel prices would motivate more efficient energy conservation. In international comparison, consumer prices of energy have been relatively low in Finland. This applies especially to electricity. After the removal of price controls, energy prices have been determined by the markets. The influence of the public authorities in energy pricing is put into effect through taxation. The price of energy has a fairly small effect on energy consumption in a short term, but longer term effects are more significant. Energy products are faxed in all western countries. (orig.)

    It is sometimes argued that renewables are 'expensive'. However, although it is generally true that the private costs of renewable electricity generation are certainly above those of conventional electricity, that statement fails to consider the social benefits provided by electricity from renewable energy sources (RES-E), including environmental and socioeconomic ones. This paper empirically analyses an additional albeit usually neglected benefit: the reduction in the wholesale price of electricity as a result of more RES-E generation being fed into the grid. The case of wind generation in Spain shows that this reduction is greater than the increase in the costs for the consumers arising from the RES-E support scheme (the feed-in tariffs), which are charged to the final consumer. Therefore, a net reduction in the retail electricity price results, which is positive from a consumer point of view. This provides an additional argument for RES-E support and contradicts one of the usual arguments against RES-E deployment: the excessive burden on the consumer. (author)

    We generally consider that the price elasticity of the energy demand is quite small. But it appears that strong increases in gasoline price lead to modifications in consumer behaviours. The high volatility of petroleum prices and thus gasoline prices and the strong increases since the beginning of 2000 justify an analysis of price effects on gasoline consumption. Thus, in this paper, we estimate the effects of price variations on gasoline consumption, in the short and the long-term, in two countries: the United States and India. We use a co-integration modelling to test for long-run relationship between gasoline consumption, income, price and vehicle ownership in the two countries. We use an error correction model to test for short-run prices effects and more precisely for asymmetric effects on demand of increases and decreases in gasoline prices. The main conclusions are the following. - The United States: (1) The long-term price elasticity is relatively high for an industrialised country because gasoline taxes are low (2) Households are more sensitive to a price increase than a price decrease. - India: (1) Price elasticity in the long-run is quite high but is quite small in the short run. It is not surprising for an emergent country (2) It seems that there is no asymmetric effect of price variations on gasoline consumption. (author)

    2009-02-01

    We conducted a systematic review of studies examining relationships between measures of beverage alcohol tax or price levels and alcohol sales or self-reported drinking. A total of 112 studies of alcohol tax or price effects were found, containing 1003 estimates of the tax/price-consumption relationship. Studies included analyses of alternative outcome measures, varying subgroups of the population, several statistical models, and using different units of analysis. Multiple estimates were coded from each study, along with numerous study characteristics. Using reported estimates, standard errors, t-ratios, sample sizes and other statistics, we calculated the partial correlation for the relationship between alcohol price or tax and sales or drinking measures for each major model or subgroup reported within each study. Random-effects models were used to combine studies for inverse variance weighted overall estimates of the magnitude and significance of the relationship between alcohol tax/price and drinking. Simple means of reported elasticities are -0.46 for beer, -0.69 for wine and -0.80 for spirits. Meta-analytical results document the highly significant relationships (P price measures and indices of sales or consumption of alcohol (aggregate-level r = -0.17 for beer, -0.30 for wine, -0.29 for spirits and -0.44 for total alcohol). Price/tax also affects heavy drinking significantly (mean reported elasticity = -0.28, individual-level r = -0.01, P prices and taxes are related inversely to drinking. Effects are large compared to other prevention policies and programs. Public policies that raise prices of alcohol are an effective means to reduce drinking.

    2001-11-01

    The primary purpose of this report is to provide the groundwork to develop the methods to forecast the world crude oil price. The methodology is used by both literature survey and empirical study. For this purpose, first of all, this report reviewed the present situation and the outlook of the world oil market based on oil demand, supply and prices. This analysis attempted to provide a deeper understanding to support the development of oil forecasting methods. The result of this review, in general, showed that the oil demand will be maintained annually at an average rate of around 2.4% under assumption that oil supply has no problem until 2020. The review showed that crude oil price will be a 3% increasing rate annually in the 1999 real term. This report used the contents of the summary review as reference data in order to link the KEEIOF model. In an effort to further investigate the contents of oil political economy, this report reviewed the articles of political economy about oil industry. It pointed out that the world oil industry is experiencing the change of restructuring oil industry after the Gulf War in 1990. The contents of restructuring oil industry are characterized by the 'open access' to resources not only in the Persian Gulf, but elsewhere in the world as well - especially the Caspian Sea Basin. In addition, the contents showed that the oil industries are shifted from government control to government and industry cooperation after the Gulf War. In order to examine the characters and the problems surrounding oil producing countries, this report described the model of OPEC behavior and strategy of oil management with political and military factors. Among examining the models of OPEC behavior, this report focused on hybrid model to explain OPEC behavior. In reviewing political and religious power structure in the Middle East, the report revealed that US emphasizes the importance of the Middle East for guaranteeing oil security. However, three

    1981-01-01

    The framework of the Base Case and the High Case for 1990 for Ireland, related to the demand modules of the medium-term European Communities (EC) Energy Model, is described. The modules are: Multi-national Macre-economic Module (EURECA); National Input-Output Model (EXPLOR); and National Energy Demand Model (EDM). The final results of the EXPLOR and EDM are described; one set related to the Base Case and the other related to the High Case. The forecast or projection is termed Base Case because oil prices are assumed to increase with general price inflation, at the same rate. The other forecast is termed High Case because oil prices are assumed to increase at 5% per year more rapidly than general price inflation. The EXPLOR-EDM methodology is described. The lack of data on energy price elasticities for Ireland is noted. A comparison of the Base Case with the High Case is made. (MCW)

    Petterson, J.S.

    1988-06-01

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

  5. FMCT verification: Case studies

    2001-01-01

    Full text: How to manage the trade-off between the need for transparency and the concern about the disclosure of sensitive information would be a key issue during the negotiations of FMCT verification provision. This paper will explore the general concerns on FMCT verification; and demonstrate what verification measures might be applied to those reprocessing and enrichment plants. A primary goal of an FMCT will be to have the five declared nuclear weapon states and the three that operate unsafeguarded nuclear facilities become parties. One focus in negotiating the FMCT will be verification. Appropriate verification measures should be applied in each case. Most importantly, FMCT verification would focus, in the first instance, on these states' fissile material production facilities. After the FMCT enters into force, all these facilities should be declared. Some would continue operating to produce civil nuclear power or to produce fissile material for non- explosive military uses. The verification measures necessary for these operating facilities would be essentially IAEA safeguards, as currently being applied to non-nuclear weapon states under the NPT. However, some production facilities would be declared and shut down. Thus, one important task of the FMCT verifications will be to confirm the status of these closed facilities. As case studies, this paper will focus on the verification of those shutdown facilities. The FMCT verification system for former military facilities would have to differ in some ways from traditional IAEA safeguards. For example, there could be concerns about the potential loss of sensitive information at these facilities or at collocated facilities. Eventually, some safeguards measures such as environmental sampling might be seen as too intrusive. Thus, effective but less intrusive verification measures may be needed. Some sensitive nuclear facilities would be subject for the first time to international inspections, which could raise concerns

  6. The Value of a Valuation Perspective for Theorizing about Social Change and Climate Change: A Study on Carbon Pricing in China

    Directory of Open Access Journals (Sweden)

    Anita Engels

    2018-05-01

    Full Text Available This study combines three purposes: to advance a valuation perspective for theorizing about social change and climate change; to contribute to the general debate on pricing as the dominant policy to meet climate mitigation goals; to improve our understanding of potential decarbonization processes in China. We apply a valuation perspective to an in-depth case study of an emerging carbon market in Hubei Province in Central China. The study builds on original data collected during field trips to Hubei (2014, 2015 and additional documents covering recent developments in the Chinese carbon market. It shows how putting a price on carbon in China emerges as the outcome of a long-term cultural and institutional process in which China's high-carbon growth model is increasingly contested. We emphasize the work that was required before a carbon price could emerge as a market price, and focus on the uncertainty that needed to be overcome in the complex multilevel Chinese system. We suggest that China's introduction of low-carbon policies are a side effect of other political, economic and social pressures, and that it is largely facilitated because such policies are consistent with many other changes that are occurring simultaneously both in the Chinese context and globally.

  7. Electricity pricing model in thermal generating stations under deregulation

    International Nuclear Information System (INIS)

    Reji, P.; Ashok, S.; Moideenkutty, K.M.

    2007-01-01

    In regulated public utilities with competitive power markets, deregulation has replaced the monopoly. Under the deregulated power market, the electricity price primarily depends on market mechanism and power demand. In this market, generators generally follow marginal pricing. Each generator fixes the electricity price based on their pricing strategy and it leads to more price volatility. This paper proposed a model to determine the electricity price considering all operational constraints of the plant and economic variables that influenced the price, for a thermal generating station under deregulation. The purpose of the model was to assist existing stations, investors in the power sector, regulatory authorities, transmission utilities, and new power generators in decision-making. The model could accommodate price volatility in the market and was based on performance incentive/penalty considering plant load factor, availability of the plant and peak/ off peak demand. The model was applied as a case study to a typical thermal utility in India to determine the electricity price. It was concluded that the case study of a thermal generating station in a deregulated environment showed that the electricity price mainly depended on the gross calorific value (GCV) of fuel, mode of operation, price of the fuel, and operating charges. 11 refs., 2 tabs., 1 fig

  14. Fiscal Drag as an Automatic Stability Tool, in the Case of New Regulation with Price Criteria in Automotive Sectors Special Consumption Tax (SCT

    Directory of Open Access Journals (Sweden)

    Abdurrahman TARAKTAŞ

    2017-12-01

    Full Text Available Fiscal drag is a result of real or nominal expanding economy and progressive taxation. In general, individuals are forced to enter the upper tax bracket depending on their increased income or expenditure. More tax burden can result in less consumption. Fiscal drag, lack of spending or excessive taxation can cause the economy to slow down. Traditional view suggests that fiscal drag may serve as a natural automatic stabilizer to cool the economy. However, this view ignores the supply side and in particular the potential effects of the high tax burden on economy. This study examines the extent to which the expected automatic stabilization function can be performed and the possible side effects on economic balances and income distribution of fiscal drag in our country in the case of new regulation with price criteria in automotive sectors Special Consumption Tax (SCT.

  15. Output Price Risk, Material Input Price Risk, and Price Margins: Evidence from the US Catfish Industry.

    Directory of Open Access Journals (Sweden)

    David Bouras

    2017-07-01

    Full Text Available Aim/purpose - To develop a conceptual model for analyzing the impact of output price risk and material input price risk on price margins. Design/methodology/approach - To analyze the combined effect of output price risk and material input risk on price margins, we use a series of comparative static analyses, GARCH models, and data ranging from 1990/01 to 2012/12. Findings - The theoretical results indicate that the impact of output price risk and the impact of material input price risk on price margins are ambiguous and, to a great extent, hinge on the correlation between output price and material input price. The empirical results show that whole frozen catfish price risk and live catfish price risk negatively affect the price margin for frozen catfish. The empirical results, however, indicate that the risk of the price of live catfish affects markedly the price margin for frozen whole catfish in contrast to the impact of the risk of the price of frozen whole catfish. Research implications/limitations - The empirical results have significant implications for managerial decision-making especially when crafting strategies for improving price margins. Accordingly, in order to beef up the price margin for frozen whole catfish, catfish processors may consider engaging in vertical integration. This paper has some limitations: first, it assumes that firms operate in competitive markets; second, it assumes that firms produce and sell a single product. Originality/value/contribution - Unlike earlier studies that focused solely on the effect of output price risk on price margins, this paper analyzes theoretically and empirically the impact of output price risk and material input price risk on price margins.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

  19. Studying language change using price equation and Pólya-urn dynamics.

    2012-01-01

    Language change takes place primarily via diffusion of linguistic variants in a population of individuals. Identifying selective pressures on this process is important not only to construe and predict changes, but also to inform theories of evolutionary dynamics of socio-cultural factors. In this paper, we advocate the Price equation from evolutionary biology and the Pólya-urn dynamics from contagion studies as efficient ways to discover selective pressures. Using the Price equation to process the simulation results of a computer model that follows the Pólya-urn dynamics, we analyze theoretically a variety of factors that could affect language change, including variant prestige, transmission error, individual influence and preference, and social structure. Among these factors, variant prestige is identified as the sole selective pressure, whereas others help modulate the degree of diffusion only if variant prestige is involved. This multidisciplinary study discerns the primary and complementary roles of linguistic, individual learning, and socio-cultural factors in language change, and offers insight into empirical studies of language change.

  4. Estimating commercial property prices: an application of cokriging with housing prices as ancillary information

    Science.gov (United States)

    Montero-Lorenzo, José-María; Larraz-Iribas, Beatriz; Páez, Antonio

    2009-12-01

    A vast majority of the recent literature on spatial hedonic analysis has been concerned with residential property values, with only very few examples of studies focused on commercial property prices. The dearth of studies can be attributed to some of the challenges faced in the analysis of commercial properties, in particular the scarcity of information compared to residential transactions. In order to address this issue, in this paper we propose the use of cokriging and housing prices as ancillary information to estimate commercial property prices. Cokriging takes into account the spatial autocorrelation structure of property prices, and the use of more abundant information on housing prices helps to improve the accuracy of property value estimates. A case study of Toledo in Spain, a city for which commercial activity stemming from tourism is one of the key elements of the economy in the city, demonstrates that substantial accuracy and precision gains can be obtained from the use of cokriging.

    2014-12-01

    Full Text Available In the process of preparing a state for the accession to the Euro Zone it is essential to analyze the price competitiveness of that state’s economy and the challenges that entrepreneurs will have to face in the new economic environment. In the present paper the authors want to capture some aspects of the competitiveness of the Romanian economy and implicit its entrepreneurs with emphasis on price competitiveness, whereas accession to the Euro Zone implies giving up to the independence of exchange rate policy, with a huge impact on price competitiveness. For this purpose this study will highlight a few elements on the relative importance of price competitiveness of entrepreneurs’ exports performance. The process of accessing Euro Zone creates significant changes in the existing way of conducting business and impacts significantly entire business environment – and this will become evident also for Romania.

    Consider a general equilibrium model where agents may behave strategically. Specifically, suppose some firm issues new shares. If the primary market price is controlled by the issuing institution and investors' expectations on future equity prices are constant in their share purchases, the share price on the primary market cannot exceed the secondary market share price. In certain cases this may imply strict underpricing of newly issued shares. If investors perceive an influence on future sha...

    It is recognised that the worksite catering sector is likely to play a pivotal role in influencing dietary intake in adults of working age. The present study aimed to assess the feasibility of engaging worksites in a healthy eating intervention, implementing a price incentivised main meal intervention and measuring indicative intervention responses to inform the design of a future trial. Workplaces registered with the Scottish Healthy Living Award were invited to participate. The EatSMART intervention (a reduced price, healthy meal combination plus promotions) was implemented over 10 weeks in two worksites. Implementation was assessed by observational and sales data. Indicative effects on food habits were measured using online pre- and post-intervention questionnaires. Focus group discussions and interviews were used to determine catering staff and consumer acceptability. Thirty-seven worksites were invited to participate and four worksites responded positively. Two sites (with 1600 and 500 employees, respectively) participated. Both required significant implementation support. Estimated sales data indicated that the uptake of promoted items varied by week (range 60-187 items) and by site. A poor response rate from questionnaires limited the evaluation of intervention impact. Consumers reported improved value for money and quality. Both sites reported an intention to continue the intervention delivery. Significant efforts are required to engage worksite catering teams and implement healthy eating interventions. Evaluation methods require further development to improve data collection. Responses from consumers and catering staff suggest that further work in this area would be welcomed. © 2014 The British Dietetic Association Ltd.

    Taxation is increasingly being used as an effective means of influencing behaviour in relation to harmful products. In this paper we use data from six participating countries of the International Alcohol Control Study to examine and evaluate their comparative prices and tax regimes. We calculate taxes and prices for three high-income and three middle-income countries. The data are drawn from the International Alcohol Control survey and from the Alcohol Environment Protocol. Tax systems are described and then the rates of tax on key products presented. Comparisons are made using the Purchasing Power Parity rates. The price and purchase data from each country's International Alcohol Control survey is then used to calculate the mean percentage of retail price paid in tax weighted by actual consumption. Both ad valorem and specific per unit of alcohol taxation systems are represented among the six countries. The prices differ widely between countries even though presented in terms of Purchasing Power Parity. The percentage of tax in the final price also varies widely but is much lower than the 75% set by the World Health Organization as a goal for tobacco tax. There is considerable variation in tax systems and prices across countries. There is scope to increase taxation and this analysis provides comparable data, including the percentage of tax in final price, from some middle and high-income countries for consideration in policy discussion. © 2017 The Authors Drug and Alcohol Review published by John Wiley & Sons Australia, Ltd on behalf of Australasian Professional Society on Alcohol and other Drugs.

    2010-01-01

    This paper examines market cointegration of city-gate and residential natural gas prices. Cointegration of gas prices across different segments of the industry provides evidence that deregulation has resulted into a more integrated, competitive natural gas industry where gas prices converge into a long-run equilibrium. Our results indicate prices further down the distribution line, the final two points of consumption, are cointegrated for a majority of the US states post open access and retail unbundling, although we find little evidence of perfect market integration. The two price series likewise converge to the long-run equilibrium faster post open access and retail unbundling. Results relative to state level unbundling (choice programs) reveal mixed outcomes with a few states without retail unbundling exhibiting market integration while some states with full unbundling exhibiting non-cointegration.

    Full Text Available For decades, there were many models explaining the returns earned emerged in order to fulfil the curiosity had by human. Since then, various studies and empirical findings in many countries’ stock market showedthat the empirical findings of market return explanation and the return of assets meet the different results in both clarify of model and identification of significant determinant variables.Therefore, many comparative studies between models were accomplished. In this study, the author attempts to do comparative study between two models, APT and CAPM, in Indonesian Capital Market during period 2008 until 2012.  Besides, the author also attempts to find how much inflation, interest rate, and exchange rate describe the returns earned in each sector existed in Indonesia Capital Market. As the result, the author find out that CAPM has bigger explanation power than APT in Indonesian Capital Market during period 2008-2012. Besides, the author also found that among macroeconomic factors, there are only two macroeconomic factors that can affect certain samples significantly.  They are change in BI rate, which affect AALI, ANTM, ASII, TLKM, UNTR, and change in exchange rate, which affect INDF and TLKM significantly.

  17. Price changes in the gasoline market: Are Midwestern gasoline prices downward sticky?

    International Nuclear Information System (INIS)

    1999-03-01

    This report examines a recurring question about gasoline markets: why, especially in times of high price volatility, do retail gasoline prices seem to rise quickly but fall back more slowly? Do gasoline prices actually rise faster than they fall, or does this just appear to be the case because people tend to pay more attention to prices when they're rising? This question is more complex than it might appear to be initially, and it has been addressed by numerous analysts in government, academia and industry. The question is very important, because perceived problems with retail gasoline pricing have been used in arguments for government regulation of prices. The phenomenon of prices at different market levels tending to move differently relative to each other depending on direction is known as price asymmetry. This report summarizes the previous work on gasoline price asymmetry and provides a method for testing for asymmetry in a wide variety of situations. The major finding of this paper is that there is some amount of asymmetry and pattern asymmetry, especially at the retail level, in the Midwestern states that are the focus of the analysis. Nevertheless, both the amount asymmetry and pattern asymmetry are relatively small. In addition, much of the pattern asymmetry detected in this and previous studies could be a statistical artifact caused by the time lags between price changes at different points in the gasoline distribution system. In other words, retail gasoline prices do sometimes rise faster than they fall, but this is largely a lagged market response to an upward shock in the underlying wholesale gasoline or crude oil prices, followed by a return toward the previous baseline. After consistent time lags are factored out, most apparent asymmetry disappears

We compute a measure for target price forecast accuracy that evaluates the ability of analysts to exactly forecast the ex-ante (unknown 12-month stock price. Furthermore, we determine factors that explain this accuracy. Target price accuracy is negatively related to analyst-specific optimism and stock-specific risk (measured by volatility and price-to-book ratio. However, target price accuracy is positively related to the level of detail of each report, company size and the reputation of the investment bank. The potential conflicts of interests between an analyst and a covered company do not bias forecast accuracy.

    High pharmaceutical prices and over-prescribing of high-priced pharmaceuticals in Chinese hospitals has long been criticized. Although policy makers have tried to address these issues, they have not yet found an effective balance between government regulation and market forces. Our objective was to explore the impact of market competition on pharmaceutical pricing under Chinese government regulation. Data from 11 public tertiary hospitals in three cities in China from 2002 to 2005 were used to explore the effect of generic and therapeutic competition on prices of antibiotics and cardiovascular products. A quasi-hedonic regression model was employed to estimate the impact of competition. The inputs to our model were specific attributes of the products and manufacturers, with the exception of competition variables. Our results suggest that pharmaceutical prices are inversely related to the number of generic and therapeutic competitors, but positively related to the number of therapeutic classes. In addition, the product prices of leading local manufacturers are not only significantly lower than those of global manufacturers, but are also lower than their non-leading counterparts when other product attributes are controlled for. Under the highly price-regulated market in China, competition from generic and therapeutic competitors did decrease pharmaceutical prices. Further research is needed to explore whether this competition increases consumer welfare in China's healthcare setting.

    We explored the role of price in the food purchasing patterns of Black adults and youths. We analyzed qualitative data from interviews and focus groups with socioeconomically diverse, primarily female, Black adults or parents (n = 75) and youths (n = 42) in 4 US cities. Interview protocols were locality specific, but all were designed to elicit broad discussion of food marketing variables. We performed a conventional qualitative content analysis by coding and analyzing data from each site to identify common salient themes. Price emerged as a primary influence on food purchases across all sites. Other value considerations (e.g., convenience, food quality, healthfulness of product, and family preferences) were discussed, providing a more complex picture of how participants considered the price of a product. Food pricing strategies that encourage consumption of healthful foods may have high relevance for Black persons across income or education levels. Accounting for how price intersects with other value considerations may improve the effectiveness of these strategies.

    For the carbon market, good trading mechanism is the basis for the healthy development of the carbon trading market. In order to explore the core problem of carbon price formation, our research explores the influencing factors of the price of carbon trading market. After the preliminary statistical analysis, our study found that Hubei Province is in the leading position among seven pilots in the carbon trading volume and the transaction, so our study of carbon price takes Hubei Province as sample of the empirical research. Multi-time series model and ARCH model analysis method are used in the research, we use the data of Hubei carbon trading pilot from June 2014 to December 2016 to carry out empirical research, the results found that industrial income, energy price, government intervention and the number of participating corporation have significant effect on the carbon price, which provides a meaningful reference for the other pilots in-depth study, as well as the construction of a national carbon trading market.

    2010-10-15

    Three centrifugal compressors at a pipeline station were retrofitted with higher head impellers in 2008. The owners of the station experienced vibration problems over the following 2 years that caused transmitter and position failures that were assumed to be flow-induced pulsations. A vibration and pulsation analysis indicated that the shell mode piping vibration excited by the blade pass pulsation was responsible for the failures. This study outlined factors that contributed to the vibration problem. Interferences between the compressor and shell mode piping natural frequencies were predicted, and potential excitation sources were examined. The study demonstrated how centrifugal vibration analyses can be used during the design phase to avoid costly adjustments. Recommendations included the addition of stiffeners to alter the shell modes, and the addition of constrained layer damping material to reduce resonant responses. 2 refs., 1 tab., 12 figs.

  19. Does the Lowest Bid Price Evaluation Criterion Make for a More Efficient Public Procurement Selection Criterion? (Case of the Czech Republic

    Directory of Open Access Journals (Sweden)

    Ochrana František

    2015-06-01

    Full Text Available Through the institute of public procurement a considerable volume of financial resources is allocated. It is therefore in the interest of contracting entities to seek ways of how to achieve an efficient allocation of resources. Some public contract-awarding entities, along with some public-administration authorities in the Czech Republic, believe that the use of a single evaluation criterion (the lowest bid price results in a more efficient tender for a public contract. It was found that contracting entities in the Czech Republic strongly prefer to use the lowest bid price criterion. Within the examined sample, 86.5 % of public procurements were evaluated this way. The analysis of the examined sample of public contracts proved that the choice of an evaluation criterion, even the preference of the lowest bid price criterion, does not have any obvious impact on the final cost of a public contract. The study concludes that it is inappropriate to prefer the criterion of the lowest bid price within the evaluation of public contracts that are characterised by their complexity (including public contracts for construction works and public service contracts. The findings of the Supreme Audit Office related to the inspection of public contracts indicate that when using the lowest bid price as an evaluation criterion, a public contract may indeed be tendered with the lowest bid price, but not necessarily the best offer in terms of supplied quality. It is therefore not appropriate to use the lowest bid price evaluation criterion to such an extent for the purpose of evaluating work and services. Any improvement to this situation requires a corresponding amendment to the Law on Public Contracts and mainly a radical change in the attitude of the Office for the Protection of Competition towards proposed changes, as indicated within the conclusions and recommendations proposed by this study.

    Full Text Available Derechos Digitales is a Latin American advocacy and research network focussed on freedom on the internet, privacy and copyright reform. For the pilot project a specific IDRC funded project was the notional focus of study. However in practice the effort for considering data sharing was aimed at being organisation wide. The organisation already shares reports and other resources (particularly images and infographics by default. While open data was described as being “in the DNA of the organisation” there was little practice across the network of sharing preliminary and in-process materials. Some aspects of data collection on research projects, particularly to do with copyright and legal issues, have significant privacy issues and as the organisation focuses on privacy as one of its advocacy areas this is taken very seriously. Many materials from research projects are not placed online at all. Derechos Digitales run distributed projects and this creates challenges for consistent management. Alongside this the main contact at DD changed during the course of the pilot. This exchange exemplified the challenges of maintaining organisational systems and awareness through a personnel change.

  4. Energy performance ratings and house prices in Wales: An empirical study

    Fuerst, Franz; McAllister, Pat; Nanda, Anupam; Wyatt, Pete

    2016-01-01

    This paper investigates the effect of Energy Performance Certificate (EPC) ratings on residential prices in Wales. Drawing on a sample of approximately 192,000 transactions, the capitalisation of energy efficiency ratings into house prices is investigated using two approaches. The first adopts a cross-sectional framework to investigate the effect of EPC rating on price. The second approach applies a repeat-sales methodology to investigate the impact of EPC rating on house price appreciation. Statistically significant positive price premiums are estimated for dwellings in EPC bands A/B (12.8%) and C (3.5%) compared to houses in band D. For dwellings in band E (−3.6%) and F (−6.5%) there are statistically significant discounts. Such effects may not be the result of energy performance alone. In addition to energy cost differences, the price effect may be due to additional benefits of energy efficient features. An analysis of the private rental segment reveals that, in contrast to the general market, low-EPC rated dwellings were not traded at a significant discount. This suggests different implicit prices of potential energy savings for landlords and owner-occupiers.

    Full Text Available Environmental sustainability of rural settlements based on a systematic viewpoint may be defined as a realization of sustainable development in different social, economic and environmental aspects of rural areas. Achieving this goal requires that we pay more attention to effective elements and factors through a set of sustainability indices. This research was meant to analyze sustainable factors of rural settlement in three dimensions: environmental, social and economic context using multi-criteria decision analysis and explanation of the relationships between its active and effective factors in the rural area of the Khorramdarreh County in the province of Zanjan. The research method used is the descriptive analytic approach. Data from 287 households were sampled randomly from a total of 1143 households in the four villages including: Rahmat Abad, Alvand, Baghdareh and, Sukhariz (out of 15 villages in the Khorramdarreh County. In the process of doing this research and after calculating the weights, the difference in the sustainability of environmental, social, economic and physical aspects in rural areas of this county have been determined. Data was collected using library and field research through questionnaires. Data analysis was performed by the One-Sample t Test and the Vikur and path analysis techniques, using statistical software SPSS. The findings show that environmental sustainability in the study area is half desirable. Among the different aspects of environmental sustainability, the most effective factors are physical, economic, social and environmental aspects, respectively. Little attention of policy-making –system to socio-cultural and environmental aspects, especially in practice, and rapid and unplanned utilization of production resources are the most important factors affecting this situation in two given dimensions. Although, in programmed documents the planning system agents emphasize on the socio-cultural sustainability

  6. How intrinsic values influence wines prices

    Directory of Open Access Journals (Sweden)

    Gál Péter

    2017-01-01

    Full Text Available The use of hedonic price indices is quite common in the wine economics literature, yet they mainly include scores of organoleptic tests and some dummy variables representing varieties and quality signs as geographical indications. This study focuses on the relation between the composition and the price of wines on the example of Hungarian wines. In Hungary, the wine law renders chemical analysis compulsory for all wines released to the market. The study includes five main compounds: actual alcoholic strength, total sugars, total acidity, sugar free extract and pH value and is based on hedonic price indices calculated on a sample of 2,453 wines. Results of several regressions – using different model specifications – consistently show that actual alcoholic strength, sugar content, sugar free extract and pH value are related with the price. Some characteristics have an optimal level, while in other cases the relation is linear.

    The new system is self-complete through grading to pricing. It grades non-coking coal by moisture and ash contents. Coking coal is graded by GKLT coke type and ash content. Volatile matter content is used as a supporting indexer, where necessary. Through the grade data, a coal is evaluated into a single numeral which depicts the coaly matter content and its nature or effectiveness. This value, called effective coaly matter, is converted to a relative rupee value or price index/price. Pragmatics and versatility of the system are discussed.

    Full Text Available We investigate stocks involved in the Unusual Market Activity (UMA Announcements. The Indonesian Stock Exchange occasionally issues UMA announcements when it suspects that there are unusual price increases (positive UMAs or price decreases (negative UMAs, as well as unusual increases in trading volumes. We believe that UMA announcements signal a high probability that stocks are being manipulated. We find no differences in fundamentals and trading variables between stocks in the UMA announcements and those not in the UMA announcements. Any stock is vulnerable to market manipulation. Stocks in the UMA announcements do not exhibit reversal patterns, suggesting that price effect is permanent. UMAs seem to convey relevant information, which is most likely in the form of insider type of information. Keywords: emerging market; price manipulation; unusual market activity announcement.

  19. An empirical examination of restructured electricity prices

    International Nuclear Information System (INIS)

    Knittel, C.R.; Roberts, M.R.

    2005-01-01

    We present an empirical analysis of restructured electricity prices. We study the distributional and temporal properties of the price process in a non-parametric framework, after which we parametrically model the price process using several common asset price specifications from the asset-pricing literature, as well as several less conventional models motivated by the peculiarities of electricity prices. The findings reveal several characteristics unique to electricity prices including several deterministic components of the price series at different frequencies. An 'inverse leverage effect' is also found, where positive shocks to the price series result in larger increases in volatility than negative shocks. We find that forecasting performance in dramatically improved when we incorporate features of electricity prices not commonly modelled in other asset prices. Our findings have implications for how empiricists model electricity prices, as well as how theorists specify models of energy pricing. (author)

    1992-01-01

    On a conference (Gas for Europe in the 1990's) during the Gasexpo '91 the author held a speech of which the Dutch text is presented here. Attention is paid to the current European pricing methods (prices based on the costs of buying, transporting and distributing the natural gas and prices based on the market value, which is deducted from the prices of alternative fuels), and the transparency of the prices (lack of information on the way the prices are determined). Also attention is paid to the market signal transparency and gas-gas competition, which means a more or less free market of gas distribution. The risks of gas-to-gas competition for a long term price stability, investment policies and security of supply are discussed. Opposition against the Third Party Access (TPA), which is the program to implement gas-to-gas competition, is caused by the fear of natural gas companies for lower gas prices and lower profits. Finally attention is paid to government regulation and the activities of the European Commission (EC) in this matter. 1 fig., 6 ills., 1 tab

    This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration modelling framework. The analysis is undertaken using monthly data from January 2000 to August 2011. The results suggest nonstationary long memory in the series (with orders of integration equal to or higher than 1) when breaks are not allowed for. However, endogenous break tests indicate a single break in all series except for producer prices for lignite for which two breaks are detected. When such breaks are taken into account, and with autocorrelated disturbances, evidence of mean reversion is found in practically all cases.

    This paper considers an electricity pool that includes a significant number of wind producers and is cleared through a network-constrained auction, one day in advance and on an hourly basis. The hourly auction is formulated as a two-stage stochastic programming problem, where the first stage...... represents the clearing of the market and the second stage models the system operation under a number of plausible wind production realizations. This formulation co-optimizes energy and reserve, and allows deriving both pool energy prices and balancing energy prices. These prices result in both cost recovery...... for producers and revenue reconciliation. A case study of realistic size is used to illustrate the functioning of the proposed pricing scheme....

    To our knowledge, there are no data on parental influences on child purchasing behavior of healthy or unhealthy foods. Mothers and children in ten families were given 5.00 US dollars to purchase portions of preferred fruits/vegetables and high energy-dense snack foods for each of ten trials of price manipulations. For five of the trials the price of the fruit/vegetable increased in price from 0.50 US dollars to 2.50 US dollars (in 0.50 US dollar increments), while the price of the energy-dense snack food remained constant at 1.00 US dollar. For the remaining five trials, the commodity that previously rose in price remained constant at 1.00 US dollars and the other commodity varied from 0.50 US dollars to 2.50 US dollars. Same-price elasticity was shown for both the child and parent purchases, and parent purchases were significantly related to child purchases of both healthy (regression estimate = 0.46, p snack food items were positively related to family socioeconomic status, and negatively related to child age. These results indicate that parental food choice and purchasing behaviors may play a role in the development of children's purchasing of both healthy and unhealthy foods.

    Rapid introduction of new product into the market has resulted in growing competition between retailers. Nowadays, retailers compete with one another in order to increase revenue and to maintain their position in the marketplace. This situation has forced the retailers to enhance their strategic management as well as creating competitive advantages. Generally, this situation can be observed in highly demanded product such as fashion goods and high technology electronic devices (smart phone, notebook). The consequence from the intense competition and new product introduction is difficulties in retailers pricing management. Retailers are now facing with complexity in making decisions on suitable pricing strategies and discount level for new product in association with the product life cycle. Thus, this research aims to investigate the suitable discount pricing strategies that can be integrated in every phase of product life cycle. This paper presents relationships between the discount pricing and the stages in the product life cycle in the form of conceptual diagram and mathematical expression. A system dynamic approach is used for developing the conceptual diagram and formulating the mathematical expression for the discount pricing strategies to visualize the relationship between discount pricing and product life cycle.

  6. Mid-Term Electricity Market Clearing Price Forecasting with Sparse Data: A Case in Newly-Reformed Yunnan Electricity Market

    2016-10-01

    Full Text Available For the power systems, for which few data are available for mid-term electricity market clearing price (MCP forecasting at the early stage of market reform, a novel grey prediction model (defined as interval GM(0, N model is proposed in this paper. Over the traditional GM(0, N model, three major improvements of the proposed model are: (i the lower and upper bounds are firstly identified to give an interval estimation of the forecasting value; (ii a novel whitenization method is then established to determine the definite forecasting value from the forecasting interval; and (iii the model parameters are identified by an improved particle swarm optimization (PSO instead of the least square method (LSM for the limitation of LSM. Finally, a newly-reformed electricity market in Yunnan province of China is studied, and input variables are contrapuntally selected. The accuracy of the proposed model is validated by observed data. Compared with the multiple linear regression (MLR model, the traditional GM(0, N model and the artificial neural network (ANN model, the proposed model gives a better performance and its superiority is further ensured by the use of the modified Diebold–Mariano (MDM test, suggesting that it is suitable for mid-term electricity MCP forecasting in a data-sparse electricity market.

  7. . Psychological Pricing in Modern Retailing: The Case of Wine Sector in Hard-Discounter Chains of Russia

    Full Text Available The main goal of this paper is to show if is possible to find a modern retail chain in one of the world largest economies that uses exclusively psychological pricing, as a dominant competitive advantage, in order to predominantly direct consumer behavior. Pricing, as a source of competitive advantage is the least explained in marketing literature, therefore it is important to contribute and show how psychological pricing is a source of competitive advantage. It could be an evidence to support the firm belief which exists among many retailers that greater than expected demand occurs at psychological price points. We shall analyze different retail chains belonging to so call hard-discounters in Russian Federation using method of observation and choose one sector in order to check the hypothesis. Hard-discounters are chosen since they use pricing strategies as the most important element of marketing program, much more important than products, promotion or sales channels, while Russia has been chosen as the largest growing wine market in the world.

  8. The impact of ownership on price-setting in retail-energy markets—The German case

    International Nuclear Information System (INIS)

    Nikogosian, Vigen; Veith, Tobias

    2012-01-01

    This paper analyzes whether public ownership has an impact on providers' price-setting. Under the assumption of more efficient energy provision which benefits customers a large number of former energy monopolists have been privatized in line with the liberalization of energy markets in Germany at the end of the 1990s. However, current re-municipalizations are justified by similar arguments in the public debate. Based on a dataset on the ownership structure of energy providers we find that public property or private property itself is not the decisive factor for lower retail and wholesale prices. Rather, a high ownership concentration leads to low prices, regardless of the type of owner. As public investors often seek total ownership of a provider, households, which are less willing to switch, benefit at least indirectly from public ownership. Tests for robustness of our results applying different owner and concentration measures confirm the results independently from the underlying estimation specification. - Highlights: ► No difference between publicly or privately owned companies in retail price choice. ► The higher the ownership concentration the lower the retail price. ► No ownership impact on distribution charges, regulation effective against strategic ownership decisions.

    This study examines the behavior of Swiss house prices to immigration flows for 85 districts from 2001 to 2006. The results show that the nexus between immigration and house prices holds even in an environment of low house price inflation, nationwide rent control, and modest immigration flows. An immigration inflow equal to 1% of an area's population is coincident with an increase in prices for single-family homes of about 2.7%: a result consistent with previous studies. The overall immigrati...

  10. Optimal pricing of non-utility generated electric power

    Siddiqi, S.N.; Baughman, M.L.

    1994-01-01

    The importance of an optimal pricing policy for pricing non-utility generated power is pointed out in this paper. An optimal pricing policy leads to benefits for all concerned: the utility, industry, and the utility's other customers. In this paper, it is shown that reliability differentiated real-time pricing provides an optimal non-utility generated power pricing policy, from a societal welfare point of view. Firm capacity purchase, and hence an optimal price for purchasing firm capacity, are an integral part of this pricing policy. A case study shows that real-time pricing without firm capacity purchase results in improper investment decisions and higher costs for the system as a whole. Without explicit firm capacity purchase, the utility makes greater investment in capacity addition in order to meet its reliability criteria than is socially optimal. It is concluded that the non-utility generated power pricing policy presented in this paper and implied by reliability differentiated pricing policy results in social welfare-maximizing investment and operation decisions

  14. Pricing policies for a two-part exhaustible resource cartel: the case of OPEC (world oil project). Working paper

    Energy Technology Data Exchange (ETDEWEB)

    Hnyilicza, E.; Pindyck, R.S.

    1976-04-01

    This paper examines pricing policies for OPEC under the assumption that the cartel is composed of a block of spender countries with large cash needs and a block of saver countries with little immediate need for cash and a lower rate of discount. The decision problem for the two-part cartel is embodied in a game-theoretic framework and the optimal bargaining solution is computed using results from the theory of cooperative games developed by Nash. The set of feasible bargaining points--and the corresponding Nash solution--is computed under two assumptions on the behavior of output shares: that they are subject to choice and that they are fixed at historical values. The results suggest that for fixed output shares, there is little room for bargaining and the price path approximates the optimal monopoly price path. If the shares are subject to control, optimal paths depend significantly on the relative bargaining power of each block.

    The gas deregulation process implies crucial choices concerning access to transportation networks. These choices deal with the nature, the structure and the level of access fees. This paper proposes an evaluation of different systems implemented both in Europe and North America, in relation to normative pricing references. The rules according to which shippers can buy or sell capacity represent another kind of choice that Regulators have to make. This paper proposes a simple model which demonstrates that secondary market prices should not be subject to a cap and emphasizes the need of a 'use-it-or-lose-it' rule on this market. (authors)

    Ma, Junhai; Xie, Lei

    2016-03-01

    The paper focuses on the dynamic pricing game of the duopoly air conditioner market with disturbance in demand and analyzes the influence of disturbance on the dynamic game system. Considering the demand for products, such as air conditioner, varies with different seasons, we assume three cases based on the condition of disturbance, including growth market (Case 1), declining market (Case 2) and completely random market (Case 3). By analyzing these three cases and making comparison among them, the paper shows that the growth market is more sensitive to the changing parameters such as the adjustment variable and the competitive factor than the declining market. It is more difficult to keep the system stable in a growth market. Although the demand is completely random, the dynamic system can reach a stable state, on condition that the adjustment variable is small enough. The results also indicate that the bullwhip effect between the order quantity and the actual demand is weakened gradually along with the price adjustment.

  19. Pricing Mining Concessions Based on Combined Multinomial Pricing Model

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available A combined multinomial pricing model is proposed for pricing mining concession in which the annualized volatility of the price of mineral products follows a multinomial distribution. First, a combined multinomial pricing model is proposed which consists of binomial pricing models calculated according to different volatility values. Second, a method is provided to calculate the annualized volatility and the distribution. Third, the value of convenience yields is calculated based on the relationship between the futures price and the spot price. The notion of convenience yields is used to adjust our model as well. Based on an empirical study of a Chinese copper mine concession, we verify that our model is easy to use and better than the model with constant volatility when considering the changing annualized volatility of the price of the mineral product.

    Firms commonly run field experiments to improve their freemium pricing schemes. However, they often lack a framework for analysis that goes beyond directly measurable outcomes and focuses on longer term profit. We aim to fill this gap by structuring existing knowledge on freemium pricing...... into a stylized framework. We apply the proposed framework in the analysis of a field experiment that contrasts three variations of a freemium pricing scheme and comprises about 300,000 users of a software application. Our findings indicate that a reduction of free product features increases conversion as well...... as viral activity, but reduces usage – which is in line with the framework’s predictions. Additional back-of-the-envelope profit estimations suggest that managers were overly optimistic about positive externalities from usage and viral activity in their choice of pricing scheme, leading them to give too...

    Driven by the growth of high deductibles and price transparency initiatives, patients are being encouraged to search for prices before seeking care, yet few do so. To understand why this is the case, we interviewed individuals who were offered access to a widely used price transparency website through their employer. Qualitative interviews. We interviewed individuals enrolled in a preferred provider organization product through their health plan about their experience using the price transparency tool (if they had done so), their past medical experiences, and their opinions on shopping for care. All interviews were transcribed and manually coded using a thematic coding guide. In general, respondents expressed frustration with healthcare costs and had a positive opinion of the idea of price shopping in theory, but 2 sets of barriers limited their ability to do so in reality. The first was the salience of searching for price information. For example, respondents recognized that due to their health plan benefits design, they would not save money by switching to a lower-cost provider. Second, other factors were more important than price for respondents when choosing a provider, including quality and loyalty to current providers. We found a disconnect between respondents' enthusiasm for price shopping and their reported use of a price transparency tool to shop for care. However, many did find the tool useful for other purposes, including checking their claims history. Addressing the barriers to price shopping identified by respondents can help inform ongoing and future price transparency initiatives.

    Heavy episodic ("binge") drinking of alcohol has serious public health implications, especially for youth and young adults. Previous summaries and surveys have failed to address in a comprehensive manner the effects of alcohol prices on binge drinking by gender or age group. A qualitative systematic review is performed for effects of alcohol prices (or tax surrogates) on binge drinking for three age groups: youth, young adults, and adults. Outcomes examined include binge participation, intensity and frequency. Criteria for data collection and potential sources of bias are discussed, including adequacy of price data. Price-binge relationships are judged using a 95% confidence interval (p ≤ 0.05) for statistical significance. Fifty-six relevant econometric studies were found, with studies and results distributed equally among three age groups. Also found were five natural experiments for tax reductions and six field studies. Null results or mixed results are found in more than half of the studies. The body of evidence indicates that binge drinkers are not highly-responsive to increased prices. Non-responsiveness holds generally for younger and older drinkers and for male and female binge drinkers alike. A limitation of the current literature is that results are only available for higher-income countries. Increased alcohol taxes or prices are unlikely to be effective as a means to reduce binge drinking, regardless of gender or age group.

  6. THE RELATIONSHIP BETWEEN SCARCITY OF NATURAL RESOURCES AND THEIR REAL PRICES

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available There has been a long running concern about resource depletion. Some argue this concern is misplaced, while others consider it to be an urgent problem requiring immediate action. Economists suggest that long term prices, adjusted for inflation (real prices, provide a useful and effective indicator of resource scarcity. This study tests this hypothesis in consideration of the accepted theory that traditional price deflators, such as the US consumer price index, overestimate inflation-, and accordingly-, are likely to underestimate long term commodity prices. To investigate the usefulness of real prices as an indicator of scarcity, a case study of two metals considered to be expensive (platinum and rhodium and two considered to be relatively inexpensive (copper and lead was used. Real long term price indices were constructed and econometric analysis used to determine the direction and significance of long-term price trends and whether real prices were correlated with other scarcity indicators such as the Reserves-toproduction ratio. The results show, when an appropriate adjustment is made to the deflator, long-run trends in real metal prices are all upward, and there is a significant relationship between the real prices and scarcity indicators, such as the reserves-to-production ratios, for platinum and rhodium, but not for copper and lead. These findings suggest that real prices of platinum and rhodium are more affected by their scarcity, while copper and lead prices are likely to be more dependent on other factors such as high substitutability with other virgin and recycled materials.

    This paper investigates the nexus between economic growth and oil price in small Pacific Island countries (PICs). Except Papua New Guinea, none of the 14 PICs has fossil any fuel resources. Consequently, the other 13 PICs are totally dependent on oil imports for their economic activities. Since PICs have limited foreign exchange earning capacities, as they have a very narrow range of exports and are highly dependent on foreign aid, high oil prices in recent months have seriously tested their economic resilience. This paper applies the ARDL bounds testing methodology to four selected PICs, Samoa, Solomon Islands, Tonga and Vanuatu, which have consistent and reliable time series of data, with a view to assess the impact of oil price on economic growth. The findings are that oil price, gross domestic product and international reserve are cointegrated in all the four PICs. Further, both in the long and short runs, we observe that there is a uni-directional relationship as causality linkage runs only from oil price and international reserves to economic growth. The paper makes some policy recommendations.

  14. Mind your pricing cues.

    Anderson, Eric; Simester, Duncan

    2003-09-01

    For most of the items they buy, consumers don't have an accurate sense of what the price should be. Ask them to guess how much a four-pack of 35-mm film costs, and you'll get a variety of wrong answers: Most people will underestimate; many will only shrug. Research shows that consumers' knowledge of the market is so far from perfect that it hardly deserves to be called knowledge at all. Yet people happily buy film and other products every day. Is this because they don't care what kind of deal they're getting? No. Remarkably, it's because they rely on retailers to tell them whether they're getting a good price. In subtle and not-so-subtle ways, retailers send signals to customers, telling them whether a given price is relatively high or low. In this article, the authors review several common pricing cues retailers use--"sale" signs, prices that end in 9, signpost items, and price-matching guarantees. They also offer some surprising facts about how--and how well--those cues work. For instance, the authors' tests with several mail-order catalogs reveal that including the word "sale" beside a price can increase demand by more than 50%. The practice of using a 9 at the end of a price to denote a bargain is so common, you'd think customers would be numb to it. Yet in a study the authors did involving a women's clothing catalog, they increased demand by a third just by changing the price of a dress from $34 to $39. Pricing cues are powerful tools for guiding customers' purchasing decisions, but they must be applied judiciously. Used inappropriately, the cues may breach customers' trust, reduce brand equity, and give rise to lawsuits.

    Price regulation is an instrument between two diverging aims: The demand for low resource prices motivated by the principle of equal distribution in our day, and the desire for economical management of resources as a responsibility we have to future generations. The present publication investigates how price regulation influences intertemporal supply of resources. For the assumed cases constant resource price, constant admissible increase in resource price, expected release of resource price and deregulation of a price held constant for a period of time mathematical models are developmed.

    The player in deregulated electricity markets can be categorized into three groups of GENCO (Generator Companies), TRNASCO (Transmission Companies), DISCO (Distribution Companies). This research focuses on the role of Distribution Companies, which purchase electricity from market at randomly fluctuating prices, and provide it to their customers at given fixed prices. Therefore Distribution companies have to take the risk stemming from price fluctuation of electricity instead of the customers. This entails the necessity to develop a certain method to make an optimal strategy for electricity procurement. In such a circumstance, this research has the purpose for proposing the mathematical method based on stochastic dynamic programming to evaluate the value of a long-term bilateral contract of electricity trade, and also a project of combination of the bilateral contract and power generation with their own generators for procuring electric power in deregulated market.

    We investigate the firm's dynamic nonlinear pricing problem when facing consumers whose tastes vary according to a scalar index. We relax the standard assumption that the firm knows the distribution of this index. In general the firm should determine its marginal price schedule as if it were myopic, and produce information by lowering the price schedule; “bunching” consumers at positive purchase levels should be avoided. As a special case we also consider a market characterized by homogeneous...

  1. International Pricing Strategies for Born-Global Firms

    Full Text Available This paper aims to understand how born global firms develop their international pricing strategies, practices, and models. It aims to expand the study of international entrepreneurship and born global firms by including a broader and deeper range of pricing aspects than is normally found in the international entrepreneurship and pricing literature. The paper opted for a multiple case-study research design using different sources of evidence, including four in-depth interviews with CEOs of born global firms. The case-study firms were selected using a purposive selection method. The theoretical framework of Ingenbleek, Frambach & Verhallen is used. The results suggest that successful leaders act as ‘integrating forces’ on two levels: by applying a structured and disciplined price-setting process with regular reviews and by mediating between corporate financial goals and the local market reality. The results support the claim that policy makers should offer insights, training and financial support to give promising born global firms the possibility to select the most efficient international pricing models and strategies. The results are relevant for entrepreneurs to understand the importance of efficient price-modelling processes and the influence of the different price strategies and price models on financial results and sales revenues.

    A review is given of the development of wind power and the pricing system in China. In particular, the report looks at the existing wind concession projects and sums up the lessons learned. The report finds that the current tender system for wind pricing needs to be improved in order to build a fair environment for the wind industry competition. Special attention should be paid to restricting the phenomenon of unreasonably low and unreasonably high wind tariffs, to facilitate the long-term development of the Chinese wind industry.

  3. Empirical effects of policy induced competition in the electricity industry : the case of district heat pricing in Finland 1996-2002

    International Nuclear Information System (INIS)

    Peltola-Ojala, P.; Linden, L.

    2007-01-01

    Following open-market competition in Finland's household electricity markets, the Electricity Market Authority began regulation of electricity and distribution networks to limit unreasonable pricing and to separate the different business units, notably production, distribution and sales. The district heating industry in Finland is regulated through general Competition Laws. The district heating industry is considered to have a regional monopoly within its distribution network and the level of public ownership within the industry is high. This paper presented the results of a study that analyzed how the policy induced competition in the electricity industry in Finland has affected the district heating industry. Both the electricity and district heating industries compete in the same household heating markets. The impact of competition was studied through pricing behaviour using panel data models. The data was gathered from 76 district district heating companies in Finland from 1996 to 2002. It was shown that the price of district heating decreased slightly as a result of electricity market reform, but the effect was short-term. The price decrease was stronger in apartment buildings than in small houses. The results suggest that the district heat markets are non-competitive and some evidence which supports regulatory threat hypothesis can be found. It was suggested that large and market dominant firms are more responsive to policy reform compared to small firms. 16 refs., 5 tabs., 2 figs., 3 appendices

    These six case studies examined the use of different biodiesel blends as fuel supply sources for businesses in British Columbia (BC). In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not

    The electricity industry throughout the world is currently undergoing a significant transition towards restructuring and deregulation. Following this new legislation, Thailand has initiated an institutional and structural reform with a belief that this could be the best way forward for the Thai electricity supply industry (ESI) to improve efficiency, lower electricity prices, and tackle financial debts. This paper presents an analysis of the extent to which prices for generation services in a competitive market may differ from regulated electricity prices, if competitive prices are based on marginal costs and regulated prices are based on average costs, by using Thailand as a case study.

    To evaluate the potential impact of two alcohol control policies under consideration in England: banning below cost selling of alcohol and minimum unit pricing. Modelling study using the Sheffield Alcohol Policy Model version 2.5. England 2014-15. Adults and young people aged 16 or more, including subgroups of moderate, hazardous, and harmful drinkers. Policy to ban below cost selling, which means that the selling price to consumers could not be lower than tax payable on the product, compared with policies of minimum unit pricing at £0.40 (€0.57; $0.75), 45 p, and 50 p per unit (7.9 g/10 mL) of pure alcohol. Changes in mean consumption in terms of units of alcohol, drinkers' expenditure, and reductions in deaths, illnesses, admissions to hospital, and quality adjusted life years. The proportion of the market affected is a key driver of impact, with just 0.7% of all units estimated to be sold below the duty plus value added tax threshold implied by a ban on below cost selling, compared with 23.2% of units for a 45 p minimum unit price. Below cost selling is estimated to reduce harmful drinkers' mean annual consumption by just 0.08%, around 3 units per year, compared with 3.7% or 137 units per year for a 45 p minimum unit price (an approximately 45 times greater effect). The ban on below cost selling has a small effect on population health-saving an estimated 14 deaths and 500 admissions to hospital per annum. In contrast, a 45 p minimum unit price is estimated to save 624 deaths and 23,700 hospital admissions. Most of the harm reductions (for example, 89% of estimated deaths saved per annum) are estimated to occur in the 5.3% of people who are harmful drinkers. The ban on below cost selling, implemented in the England in May 2014, is estimated to have small effects on consumption and health harm. The previously announced policy of a minimum unit price, if set at expected levels between 40 p and 50 p per unit, is estimated to have an approximately 40-50 times

    This paper is the first to consider a large scale natural experiment to estimate the effect of taxes on house prices. We find that a 1 percentage-point increase in income tax rates lead to a drop in house prices of at most 2.2%. This corresponds to a tax capitalization for the average household...... capitalization from earlier studies. Furthermore, we find no effect of property taxes on house prices. We attribute this to the low levels of Danish municipal property tax rates compared to income tax rates....

  10. Marketplace pricing

    International Nuclear Information System (INIS)

    1991-01-01

    As discussed in this chapter, interest in marketplace pricing has been increasing in recent years, reflecting the societal trend toward substituting competition for regulation where appropriate. Competition is valuable because it encourages utilities to make efficient decisions with a minimum of regulatory intervention. It enhances efficiency through the incentive for innovation by the regulated companies and by increasing the likelihood they will come forward with proposals for better services, lower prices or both. Ultimately, consumers are beneficiaries. Marketplace pricing is emblematic of the view that the degree of regulation should reflect the degree of market power, that workably competitive markets should be allowed to operate with as little regulatory interference as possible. The Edison Electric Institute has made perhaps the most detailed proposal on marketplace pricing. It and others perceive numerous benefits from this method of pricing transmission services. Given the undeniable market power resulting from line ownership, FERC has emphasized the need to find a workably competitive market before approving such proposals. The ability to make this distinction without a full-blown antitrust review for every transaction is questionable, and FERC has yet to provide generic guidance. Finally, FERC's legal ability to depart from cost-based standards is questionable

    Minimum unit pricing of alcohol is a novel public health policy with the potential to improve population health and reduce health inequalities. Theories of the policy process may help to understand the development of policy innovation and in turn identify lessons for future public health research and practice. This study aims to explain minimum unit pricing's development by taking a 'multiple-lenses' approach to understanding the policy process. In particular, we apply three perspectives of the policy process (Kingdon's multiple streams, Punctuated-Equilibrium Theory, Multi-Level Governance) to understand how and why minimum unit pricing has developed in Scotland and describe implications for efforts to develop evidence-informed policymaking. Semi-structured interviews were conducted with policy actors (politicians, civil servants, academics, advocates, industry representatives) involved in the development of MUP (n = 36). Interviewees were asked about the policy process and the role of evidence in policy development. Data from two other sources (a review of policy documents and an analysis of evidence submission documents to the Scottish Parliament) were used for triangulation. The three perspectives provide complementary understandings of the policy process. Evidence has played an important role in presenting the policy issue of alcohol as a problem requiring action. Scotland-specific data and a change in the policy 'image' to a population-based problem contributed to making alcohol-related harms a priority for action. The limited powers of Scottish Government help explain the type of price intervention pursued while distinct aspects of the Scottish political climate favoured the pursuit of price-based interventions. Evidence has played a crucial but complex role in the development of an innovative policy. Utilising different political science theories helps explain different aspects of the policy process, with Multi-Level Governance particularly useful for

    New psychoactive substances (NPS) are on offer worldwide online, in order to shed light on the purity and price of these substances in the European Union, a research collaboration was set up involving France, United Kingdom (UK), the Netherlands, Czech Republic and Poland. Per country, around 10 different NPS were test purchased from different webshops. Then, chemical analysis of NPS was done with according reference standards to identify and quantify the contents. In contrast to what is generally advertised on the webshops (>99%), purity varied considerably per test purchased NPS. Several NPS were mislabelled, some containing chemical analogues (e.g. 25B/C-NBOMe instead of 25I-NBOMe, pentedrone instead of 3,4-DMMC). But in some cases NPS differed substantially from what was advertised (e.g. pentedrone instead of AMT or 3-FMC instead of 5-MeO-DALT). Per gram, purity-adjusted prices of cathinones differed substantially between three countries of test purchase, with Poland being the least expensive. Synthetic cannabinoids were relatively the most expensive in the Czech Republic and least expensive in the UK. The current findings provides a snapshot of the price and chemical contents of NPS products purchased by different countries and in different webshops. There is a potential danger of mislabelling of NPS. The great variety in price and purity of the delivered products might be the result of the market dynamics of supply and demand and the role of law enforcement in different European countries.

    2010-08-01

    New vaccine pricing is a complicated process that could have substantial long-standing scientific, medical, and public health ramifications. Pricing can have a considerable impact on new vaccine adoption and, thereby, either culminate or thwart years of research and development and public health efforts. Typically, pricing strategy consists of the following ten components: 1. Conduct a target population analysis; 2. Map potential competitors and alternatives; 3. Construct a vaccine target product profile (TPP) and compare it to projected or actual TPPs of competing vaccines; 4. Quantify the incremental value of the new vaccine's characteristics; 5. Determine vaccine positioning in the marketplace; 6. Estimate the vaccine price-demand curve; 7. Calculate vaccine costs (including those of manufacturing, distribution, and research and development); 8. Account for various legal, regulatory, third party payer, and competitor factors; 9. Consider the overall product portfolio; 10. Set pricing objectives; 11. Select pricing and pricing structure. While the biomedical literature contains some studies that have addressed these components, there is still considerable room for more extensive evaluation of this important area.

    Caginalp, G; Porter, D; Smith, V

    1998-01-20

    A series of experiments, in which nine participants trade an asset over 15 periods, test the hypothesis that an initial imbalance of asset/cash will influence the trading price over an extended time. Participants know at the outset that the asset or "stock" pays a single dividend with fixed expectation value at the end of the 15th period. In experiments with a greater total value of cash at the start, the mean prices during the trading periods are higher, compared with those with greater amount of asset, with a high degree of statistical significance. The difference is most significant at the outset and gradually tapers near the end of the experiment. The results are very surprising from a rational expectations and classical game theory perspective, because the possession of a large amount of cash does not lead to a simple motivation for a trader to bid excessively on a financial instrument. The gradual erosion of the difference toward the end of trading, however, suggests that fundamental value is approached belatedly, offering some consolation to the rational expectations theory. It also suggests that there is a time scale on which an evolution toward fundamental value occurs. The experimental results are qualitatively compatible with the price dynamics predicted by a system of differential equations based on asset flow. The results have broad implications for the marketing of securities, particularly initial and secondary public offerings, government bonds, etc., where excess supply has been conjectured to suppress prices.

    Value-based pricing (VBP), whereby prices are set according to the perceived benefits offered to the consumer at a time when costs and benefits are characterized by considerable uncertainty and are then reviewed ex post, is a much discussed topic in pharmaceutical reimbursement. It is usually combined with coverage with evidence development (CED), a tool in which manufacturers are granted temporary reimbursement but are required to collect and submit additional health economic data at review. Many countries, including the UK, are signalling shifts in this direction. Several countries, including Sweden, have already adopted this approach and offer good insight into the benefits and pitfalls in actual practice. To describe VBP reimbursement decision making using CED in actual practice in Sweden. Decision making by The Dental and Pharmaceutical Benefits Agency (TLV) in Sweden was reviewed using a case study of continuous intraduodenal infusion of levodopa/carbidopa (Duodopa®) in the treatment of advanced Parkinson's disease (PD) with severe motor fluctuations. The manufacturer of Duodopa® applied for reimbursement in late 2003. While the proper economic data were not included in the submission, TLV granted reimbursement until early 2005 to provide time for the manufacturer to submit a formal economic evaluation. The re-submission with economic data was considered inadequate to judge cost effectiveness, so TLV granted an additional extension of reimbursement until August 2007, at which time conclusive data were expected. The manufacturer initiated a 3-year, prospective health economic study and a formal economic model. Data from a pre-planned interim analysis of the data were loaded into the model and the cost-effectiveness ratio was the basis of the next re-submission. TLV concluded that the data were suitable for making a definite decision and that the drug was not cost effective, deciding to discontinue reimbursement for any new patients (current patients were

    Some characteristics of the electricity load and prices are studied, and the relationship between electricity prices and gas (fuel) prices is analyzed in this paper. Because electricity prices are strongly dependent on load and gas prices, the authors constructed a model for electricity prices based on the effects of these two factors; and used the Geometric Mean Reversion Brownian Motion (GMRBM) model to describe the electricity load process, and a Geometric Brownian Motion(GBM) model to describe the gas prices; deduced the price stochastic process model based on the above load model and gas price model. This paper also presents methods for parameters estimation, and proposes some methods to solve the model.

    Full Text Available In the conditions of globalization all the companies try to find the effective ways of maximizing their profit. One of the instruments is the system of the transfer pricing that helps to optimize the costs and allocate effective the resources of the company. Transfer pricing has detrimental effect on the economy of countries, though the governments use the regulations to minimize this effect on their economy. In this case the conflict of interests appears. Paper deals with an analysis of the functions and reasons of the economic agents which use the transfer prices to demonstrate the conflict of interests in transfer pricing. The purpose of the study is the determination of the best ways to solve the conflict situations in the process of transfer pricing according to the economic interests of the agents: company and government and within the company: headquarters and subsidiaries. The main point of resolving the conflict between company and government is to make clear regulations of transfer pricing for enterprises and productive relations between company and government. The methods to resolve the conflict within the company are: clear guidelines, decentralization and motivation for stuff members.

    Full Text Available The curtailment of wind power and photovoltaic power is becoming increasingly serious from the year 2012 to present in China. And the small installed capacity captive coal-fired power plants have been developed rapidly aiming to cut production costs. Therefore, by the substitution of renewable energy for captive coal-fired power plants, this paper establishes a time-of-use (TOU pricing mechanism with a linkage between the supply side and the demand side to promote renewable energy consumption, which is applied to the Western Inner Mongolia grid in China. The results show that the benefits to the grid company, electricity users, renewable energy producers, and social environment are influenced by the quantity of renewable energy purchased in the market, the market price for renewable energy, the quantity of electricity from grid to peak shaving, the carbon price, and the quantity of electricity generated by captive coal-fired power plants shifting to grid, in which the first factor has the greatest influence on the benefits of stakeholders. Furthermore, improving the accuracy of renewable energy generation forecast and optimizing using electricity behaviors by considering the renewable energy generation characteristics could ensure the TOU mechanism implementation successfully.

    Electricity pricing in most countries, especially in the developing world, has been determined by traditional accounting criteria where it raises revenue requirements to cover the operating costs and a return on past and future capital investments in possible power systems. The use of economic principles to improve the total economic efficiency in the electricity industry is discussed. Basic marginal cost theory, long run marginal costing (LRMC) cost categories and rating periods, marginal capacity costs, marginal energy costs, consumer costs, short run marginal costing (SRMC), marginal cost of fuel, marginal cost of network losses, market clearing price, value of unserved energy and network quality of supply cost are discussed

    Full Text Available Abstract Background UK drinkers regularly consume alcohol in excess of guideline limits. One reason for this may be the high availability of low-cost alcoholic beverages. The introduction of a minimum price per unit of alcohol policy has been proposed as a means to reduce UK alcohol consumption. However, there is little in-depth research investigating public attitudes and beliefs regarding a minimum pricing policy. The aim of the present research was to investigate people’s attitudes and beliefs toward the introduction of a minimum price per unit of alcohol policy and their views on how the policy could be made acceptable to the general public. Methods Twenty-eight focus groups were conducted to gain in-depth data on attitudes, knowledge, and beliefs regarding the introduction of a minimum price per unit of alcohol policy. Participants (total N = 218 were asked to give their opinions about the policy, its possible outcomes, and how its introduction might be made more acceptable. Transcribed focus-group discussions were analysed for emergent themes using inductive thematic content analysis. Results Analysis indicated that participants’ objections to a minimum price had three main themes: (1 scepticism of minimum pricing as an effective means to reduce harmful alcohol consumption; (2 a dislike of the policy for a number of reasons (e.g., it was perceived to ‘punish’ the moderate drinker; and (3 concern that the policy might create or exacerbate existing social problems. There was a general perception that the policy was aimed at ‘problem’ and underage drinkers. Participants expressed some qualified support for the policy but stated that it would only work as part of a wider campaign including other educational elements. Conclusions There was little evidence to suggest that people would support the introduction of a minimum price per unit of alcohol policy. Scepticism about the effectiveness of the policy is likely to represent the most

    Background UK drinkers regularly consume alcohol in excess of guideline limits. One reason for this may be the high availability of low-cost alcoholic beverages. The introduction of a minimum price per unit of alcohol policy has been proposed as a means to reduce UK alcohol consumption. However, there is little in-depth research investigating public attitudes and beliefs regarding a minimum pricing policy. The aim of the present research was to investigate people’s attitudes and beliefs toward the introduction of a minimum price per unit of alcohol policy and their views on how the policy could be made acceptable to the general public. Methods Twenty-eight focus groups were conducted to gain in-depth data on attitudes, knowledge, and beliefs regarding the introduction of a minimum price per unit of alcohol policy. Participants (total N = 218) were asked to give their opinions about the policy, its possible outcomes, and how its introduction might be made more acceptable. Transcribed focus-group discussions were analysed for emergent themes using inductive thematic content analysis. Results Analysis indicated that participants’ objections to a minimum price had three main themes: (1) scepticism of minimum pricing as an effective means to reduce harmful alcohol consumption; (2) a dislike of the policy for a number of reasons (e.g., it was perceived to ‘punish’ the moderate drinker); and (3) concern that the policy might create or exacerbate existing social problems. There was a general perception that the policy was aimed at ‘problem’ and underage drinkers. Participants expressed some qualified support for the policy but stated that it would only work as part of a wider campaign including other educational elements. Conclusions There was little evidence to suggest that people would support the introduction of a minimum price per unit of alcohol policy. Scepticism about the effectiveness of the policy is likely to represent the most significant barrier to

    The fluctuations in oil prices are very complicated and therefore, it is unable to predict its effects on economies. For modelling complex system of oil prices, linear economic models are not sufficient and efficient tools. Thus, in recent years, economists attached great attention to non-linear structure of oil prices. For analyzing this relationship, GARCH types of models were used in some papers. Distinctively from the other papers, in this study, we aimed to analyze chaotic pattern of oil prices. Thus, it was used the Lyapunov Exponents and Hennon Map to determine chaotic behavior of oil prices for the selected time period.

  12. House Prices and Public Debt

    DEFF Research Database (Denmark)

    Gjedsted Nielsen, Mads; Rzeznik, Aleksandra

    By using the 2002 case of fraud in the Danish municipality Farum by then mayor Peter Brixtofte as an exogenous shock to public debt of 1 billion DKK, I estimate the effect of public debt on house prices. I find that the average home ownership lost about 570,000 DKK or as much as 29% of the average...... house price in the municipality. Furthermore, I document that the aggregate house price loss of 2.1 billion DKK greatly exceeds the increase in public debt of 1 billion DKK. I find that the drop in house prices is sustained 1 year, indicating that the housing market initially overreacts...

    Hundreds of drug products are currently marketed in the United States without approval from the FDA. The 2006 Unapproved Drugs Initiative (UDI) requires manufacturers to remove these drug products from the market or obtain FDA approval by demonstrating evidence of safety and efficacy. Once the FDA acts against an unapproved drug, fewer manufacturers remain in the market, potentially enabling drug price increases and greater susceptibility to drug shortages. There is a need for systematic study of the UDI's effect on prices and shortages of all targeted drugs. To examine the clinical evidence for approval and association with prices and shortages of previously unapproved prescription drugs after being addressed by the UDI. Previously unapproved prescription drugs that faced UDI regulatory action or with at least 1 product that received FDA approval through manufacturers' voluntary compliance with the UDI between 2006 and 2015 were identified. The clinical evidence was categorized as either newly conducted clinical trials or use of previously published literature and/or bioequivalence studies to demonstrate safety and efficacy. We determined the change in average wholesale price, presence of shortage, and duration of shortage for each drug during the 2 years before and after UDI regulatory action or approval through voluntary compliance. Between 2006 and 2015, 34 previously unapproved prescription drugs were addressed by the UDI. Nearly 90% of those with a drug product that received FDA approval were supported by literature reviews or bioequivalence studies, not new clinical trial evidence. Among the 26 drugs with available pricing data, average wholesale price during the 2 years before and after voluntary approval or UDI action increased by a median of 37% (interquartile range [IQR] = 23%-204%; P Innovation; from the Blue Cross Blue Shield Association to better understand medical technology evidence generation; from the Centers for Medicare & Medicaid Services to

    Electricity has played an important role in the economic development of Korea and, thus, has become a critical factor in sustaining the well-being of the Korean people. This study attempts to investigate the impact of electricity price changes on industrial prices and the general price level using input–output (I–O) analysis. To this end, we apply the I–O price model to the 2011 I–O table recently produced by the Bank of Korea, paying particular attention to the electricity sector by considering it as exogenous and then investigating its impacts. The impacts of the electricity price changes on each industrial sector's prices and the general price level are quantitatively derived. For example, the overall impact of a 10% increase in electricity price on the Korean national economy is estimated to be 0.4367%. We also report the results from the model with the electricity sector endogenous and the model with endogenous electricity and labor sectors. This information can be usefully utilized in decision-making regarding price management for electricity. - Highlights: • We investigate the impact of electricity price changes on the Korean economy. • We use the input–output (I–O) analysis specifying the electricity sector as exogenous. • We apply the I–O price model to 2010 I–O table produced by the Bank of Korea. • The impact of a 10% increase in electricity price on the Korean economy is 0.2176%

    Stock price prediction is an important and challenging problem for studying financial markets. Existing studies are mainly based on the time series of stock price or the operation performance of listed company. In this paper, we propose to predict stock price based on investors' trading behavior. For each stock, we characterize the daily trading relationship among its investors using a trading network. We then classify the nodes of trading network into three roles according to their connectivity pattern. Strong Granger causality is found between stock price and trading relationship indices, i.e., the fraction of trading relationship among nodes with different roles. We further predict stock price by incorporating these trading relationship indices into a neural network based on time series of stock price. Experimental results on 51 stocks in two Chinese Stock Exchanges demonstrate the accuracy of stock price prediction is significantly improved by the inclusion of trading relationship indices.

  18. Empirical study of peak-load pricing and investment policies for the domestic market of gas in Great Britain

    This paper reports the main results of a study aimed at determining empirically an optimal structure of seasonal tariffs for the domestic sector of gas in Great Britain. The study first involves the development of a peak-load pricing model which maximizes social welfare. The model is then quantified with cost and demand functions which have been statistically estimated for Great Britian using data for town gas. The procedure of estimating these functions is based on an error components model. The seasonal pricing and investment policy resulting from the solution to the above model is then compared with the existing policy for the domestic sector of gas in Great Britain. It is shown that the former is superior to the latter in terms of improvements in social welfare and capacity utilization. 22 references.

    This article deals with the trends of the main fuel prices development in the Western European markets. There are two possible price development scenarios presented in the article. Transportation costs of various internationally traded fuels from various sources (Russia, Western Europe) are estimated and their most feasible values are considered. Fuel prices for the final big consumers are calculated adding the domestic distribution costs. Trends of heat and electricity price development in Lithuania during the period of 1991-1995 are analyzed. Forecasts of the electricity generation and supply costs are calculated according to various scenarios. Electricity prices will be lowest in the case of the further operation of the Ignalina NPP and low fuel prices in international markets. (author). 8 refs., 14 figs., 4 tabs

    Legislation in NYC requires chain restaurants to post calorie information on menu boards in an effort to help consumers make more informed decisions about food and beverage items they are purchasing. While this is a step in the right direction in light of the current obesity epidemic, there are other issues that warrant attention in a fast food setting, namely the pricing of healthy food options, promotional strategies, and access to comprehensive nutrition information.
