    OpenAIRE

    Ramos Gutierrez, Ariana Isabel; De Jonghe, Cedric; Six, Daan; Belmans, Ronnie

    2013-01-01

    The introduction of intermittent energy resources calls for the ability to modulate consumption patterns according to electricity availability. This paper provides a brief overview of the main electricity market design characteristics and places demand response within the framework of the existing timeline of market operation. The main differences between electricity markets lie in the price formation mechanisms where some markets pay-as- cleared and some pay- as- bid for the electricity tran...

  2. Evolution and current status of demand response (DR) in electricity markets: Insights from PJM and NYISO

    In electricity markets, traditional demand side management programs are slowly getting replaced with demand response (DR) programs. These programs have evolved since the early pilot programs launched in late 1990s. With the changes in market rules the opportunities have generally increased for DR for participating in emergency, economic and ancillary service programs. In recent times, various regulators have suggested that DR can also be used as a solution to meet supply - demand fluctuations in scenarios with significant penetration of variable renewable sources in grid. This paper provides an overview of the evolution of the DR programs in PJM and NYISO markets as well as analyzes current opportunities. Although DR participation has grown, most of the current participation is in the reliability programs, which are designed to provide load curtailment during peak days. This suggests that there is a significant gap between perception of ability of DR to mitigate variability of renewables and reality of current participation. DR in future can be scaled to play a more dynamic role in electricity markets, but that would require changes both on technology as well as policy front. Advances in building technologies and energy storage combined with appropriate price signals can lead to enhanced DR participation. (author)

  3. Current supply/demand outlook and its impact on gas marketing strategies

    1994-01-01

    The current supply/demand outlook for natural gas in Canada is discussed, starting with a review of natural gas supply trends since the deregulation of the market in 1985/86. Market demand trends and expansion of export pipeline capacity are summarized to demonstrate how radically the North American gas marketing industry has changed in the last decade. As of January 1st 1993, Canada ranked eleventh in the world with respect to remaining natural gas reserves (96 Tft 3 ), which represents only 2% of global gas reserves. Canada ranks third in gas production (5 Tft 3 /y), behind the USA and former Soviet Union (19 and 29 Tft 3 /y, respectively). In western Canada, gas production rates have increased 75% since deregulation. Canadian domestic demand has grown 24% since 1985 to the 1993 level of 2.1 Tft 3 /y, while exports to the USA have grown 144% to 2.2 Tft 3 /y. The present environment requires a 'just in time' attitude towards developing new gas reserves and arranging transportation and storage. Long term gas marketing transacations are increasingly deliverability-based, firm delivery commitments which include harsh penalties for nonperformance. 7 figs

  4. Demand response in energy markets

    2004-11-01

    Improving the ability of energy demand to respond to wholesale prices during critical periods of the spot market can reduce the total costs of reliably meeting demand, and the level and volatility of the prices. This fact has lead to a growing interest in the short-run demand response. There has especially been a growing interest in the electricity market where peak-load periods with high spot prices and occasional local blackouts have recently been seen. Market concentration at the supply side can result in even higher peak-load prices. Demand response by shifting demand from peak to base-load periods can counteract the market power in the peak-load. However, demand response has so far been modest since the current short-term price elasticity seems to be small. This is also the case for related markets, for example, green certificates where the demand is determined as a percentage of the power demand, or for heat and natural gas markets. This raises a number of interesting research issues: 1) Demand response in different energy markets, 2) Estimation of price elasticity and flexibility, 3) Stimulation of demand response, 4) Regulation, policy and modelling aspects, 5) Demand response and market power at the supply side, 6) Energy security of supply, 7) Demand response in forward, spot, ancillary service, balance and capacity markets, 8) Demand response in deviated markets, e.g., emission, futures, and green certificate markets, 9) Value of increased demand response, 10) Flexible households.

    Demand response is a cornerstone problem in electricity markets considering climate change constraint. Most liberalized electricity markets have a poor track record at developing demand response. In Europe, different models are considered for demand response, from a development under a regulated regime to a development under competitive perspectives. In this paper, focusing on demand response for mid-size and small consumers, we investigate which types of market signals should be sent to demand response aggregators to see demand response emerge as a competitive activity. Using data from the French power system over eight years, we compare the possible market design options to allow demand response to develop. Our simulations demonstrate that with the current market rules, demand response is not a profitable activity in the French electricity industry. Introducing a capacity remuneration could bring additional revenues to demand response aggregators if the power system has no over-capacity

    Full Text Available As librarianship evolves, it is important to examine the changes that have taken place in professional requirements. To provide an understanding of the current market demand for core competencies of librarianship, this article conducts a semi-automatic methodology to analyze job advertisements (ads posted on the American Library Association (ALA Joblist from 2009 through 2014. There is evidence that the ability to solve unexpected complex problems and to provide superior customer service gained increasing importance for librarians during those years. The authors contend that the findings in this report question the status quo of core competencies of librarianship in the US job market.

    The forecast is for the years 1981 - 2000 with benchmark years at 1985, 1990 and 2000. Two typs of markets are considered for this study: Hardware (worldwide total) - satellites, earth stations and control facilities (includes replacements and spares); and non-hardware (addressable by U.S. industry) - planning, launch, turnkey systems and operations. These markets were examined for the INTELSAT System (international systems and domestic and regional systems using leased transponders) and domestic and regional systems. Forecasts were determined for six worldwide regions encompassing 185 countries using actual costs for existing equipment and engineering estimates of costs for advanced systems. Most likely (conservative growth rate estimates) and optimistic (mid range growth rate estimates) scenarios were employed for arriving at the forecasts which are presented in constant 1980 U.S. dollars. The worldwide satellite market demand forecast predicts that the market between 181 and 2000 will range from $35 to $50 billion. Approximately one-half of the world market, $16 to $20 billion, will be generated in the United States.

    Utility load management programs, including direct load control and interruptible load programs, constitute a large installed base of controllable loads that are employed by utilities as system reliability resources. In response to energy supply shortfalls expected during the summer of 2001, the California Public Utilities Commission in spring 2001 authorized new utility load management programs as well as revisions to existing programs. This report provides an independent review of the designs of these new programs for a large utility (Southern California Edison) and suggests possible improvements to enhance the price responsiveness of the customer actions influenced by these programs. The report also proposes a new program to elicit a mass-market demand response to utility price signals.

    The big volume of gas supplies for current and future energy and natural gas balances in Russia is important to understand the likely future dynamics of demand for gas. The path of future demand in Russia is uncertain and the range of possible scenarios is wide. For creating the new gas consumption structure, more deep diversification and development of the gas distribution systems, large investments and considerable periods of time are necessary. The factors usually studied in detail in the conditions of market economy can not be used here as a basis for strategic planning due to several reasons. (R.P.)

    The speaker discussed the situation of gas supply and demand in the eastern part of North America. The first PowerPoint slide provided the outline of the presentation. The author showed maps detailing the regional gas demand, first in Ontario, Quebec and the Maritimes, then New England. The next few slides depicted the North American power generation capacity, and the market fundamentals of supply. The Canadian East Coast Forecast Production was shown, and the impact of liquid natural gas (LNG) and Sable deliveries through 2010 explained. The key themes for the next ten years were explored and the situation of Sable gas to Quebec as of 23 May 2001 was described. The implications for the Quebec market are many: Quebec is now receiving Sable gas and its connection with the Portland market is proving very useful. It all leads to growing confidence on the part of industrial gas users. The author concluded the presentation with a few thoughts: (1) moderate demand growth in Central Canada, (2) stronger growth in New England, (3) power generation is a key driver of demand, (4) LNG, East Coast and Arctic gas will be key supply sources, and (5) Sable gas to Quebec. figs

  17. Modelling of demand response and market power

    Kristoffersen, B.B.; Donslund, B.; Boerre Eriksen, P.

    2004-01-01

    Demand-side flexibility and demand response to high prices are prerequisites for the proper functioning of the Nordic power market. If the consumers are unwilling to respond to high prices, the market may fail the clearing, and this may result in unwanted forced demand disconnections. Being the TSO of Western Denmark, Eltra is responsible of both security of supply and the design of the power market within its area. On this basis, Eltra has developed a new mathematical model tool for analysing the Nordic wholesale market. The model is named MARS (MARket Simulation). The model is able to handle hydropower and thermal production, nuclear power and wind power. Production, demand and exchanges modelled on an hourly basis are new important features of the model. The model uses the same principles as Nord Pool (The Nordic Power Exchange), including the division of the Nordic countries into price areas. On the demand side, price elasticity is taken into account and described by a Cobb-Douglas function. Apart from simulating perfect competition markets, particular attention has been given to modelling imperfect market conditions, i.e. exercise of market power on the supply side. Market power is simulated by using game theory, including the Nash equilibrium concept. The paper gives a short description of the MARS model. Besides, focus is on the application of the model in order to illustrate the importance of demand response in the Nordic market. Simulations with different values of demand elasticity are compared. Calculations are carried out for perfect competition and for the situation in which market power is exercised by the large power producers in the Nordic countries (oligopoly). (au)

  18. Demand-controlling marketing of electric utilities

    Energy Technology Data Exchange (ETDEWEB)

    Raffee, H; Fritz, W

    1980-01-01

    In situations like the shortage of energy resources the particular autonomy of the users concerning energy demand raises more and more aggravating problems for the electric utilities (EU) and, last not least, for society (i.e. the peak-load problem, threatening bottlenecks in the supply situation). Thus the requirement for a demand-controlling marketing strategy of the EU with the help of which the individual demand should be influenced in the following manner is legitimate. The article discusses the targets, strategies, and instruments of marketing performed by the EU under the aspect of their efficiency concerning demand control. The discussion leads to e.g. the following results: that a marketing strategy for the sensible, responsible, and efficent use of energy, in the long-term, serves both the interests of the users and the interests of the EU; that such a marketing programme can have the required controlling effects especially with the help of strategies like market segmentation and cooperation. The discussion makes also clear that a demand-controlling marketing strategy of the EU can hardly be realized without a considerable change within the organization of the EU on one hand and, on the other, without expanding the marketing programme toward a marketing strategy of balance.

    2012-01-01

    This paper outlines a methodology for implementing cost of service regulation in retail market for electricity in India when wholesale market is liberalised and operates through an hourly spot market. As in a developing country context political considerations make tariff levels more important than supply security, satisfying the earmarked level of demand takes a back seat. Retail market regulators are often forced by politicians to keep the retail tariff at suboptimal level. This imposes budget constraint on distribution companies to procure electricity that it requires to meet the earmarked level of demand. This is the way demand response is introduced in the system and has its impact on spot market prices. We model such a situation of not being able to serve the earmarked demand as disutility to the regulator which has to be minimised and we compute associated equilibrium. This results in systematic mechanism for cutting loads. We find that even a small cut in ability of the distribution companies to procure electricity from the spot market has profound impact on the prices in the spot market. - Highlights: ► Modelling the impact of retail tariff in different states on spot prices of electricity in India. ► Retail tariffs are usually fixed below appropriate levels by states due to political reasons. ► Due to revenue constraint distribution utility withdraws demand from spot market in peak hours. ► This adversely affects the scarcity rent of generators and subsequently future investment. ► We show possibility of strategic behaviour among state level regulators in setting retail tariff.

    Fraser, M.E.

    1990-01-01

    Ontario Hydro has a marketing strategy for designing and implementing demand side management (DSM) programs, which marks a turnaround from previous years when marketing efforts were concentrated on selling electricity. Starting in the 1980s, marketing activities consisted, in effect, of coordinating relations between the customer, the market, and the utility. To achieve a better understanding of the needs of customers, the nature of the energy market, and the utilization of energy, the utility conducted research on the decision-making process associated with consumer choices of energy systems. To develop relations with its clientele in the commercial sector, the utility published an information bulletin and prepared an energy guide. Along with this initiative, the number of energy advisers to the commercial sector was increased in Ontario Hydro's regional offices. To improve understanding of each segment of the commercial market, the utility contacted organizations representing each segment as well as broader based organizations with the objective of creating opportunities to address this market, for example at conferences. Because of this philosophy of satisfying and understanding customer needs, Ontario Hydro has been in the process of commercializing demand-side management. Its high-efficiency lighting program is a good example in this regard. From a strategy which focused on a simple reduction in lighting in the 1970s, the utility has turned toward promoting efficient high-quality lighting which better responds to industry needs, to the point where industry itself has begun to promote the program. Such a strategy benefits industry, customers, and Ontario Hydro's demand-side management programs

    Acurex Environmental Corporation is bringing Clean Fuel to the environmentally demand Krakow market, through the cooperative agreement with the U.S. Department of Energy. Clean fuel is a proprietary clean burning coal-based energy source intended for use in stoves and hand stoked boilers. Clean Fuel is a home heating fuel that is similar in form and function to raw coal, but is more environmentally friendly and lower in cost. The heating value of Clean Fuel is 24,45 kJ/kg. Extensive sets of confirmation runs were conducted in the Academy of Mining and Metallurgy in the Krakow laboratories. It demonstrated up to 54 percent reduction of particulate matter emission, up to 35 percent reduction of total hydrocarbon emissions. Most importantly, polycyclic aromatic hydrocarbons (toxic and carcinogens compounds) emissions were reduced by up to 85 percent, depending on species measured. The above comparison was made against premium chunk coal that is currently available in Krakow for approximately $83 to 93/ton. Clean Fuel will be made available in Krakow at a price approximately 10 percent lower than that of the premium chunk coal.

    Full Text Available This study aimed at analyzing the international pulp market, taking into account themain exporting countries and importing regions, with the objective of estimating, for each market, theown-price and cross-price elasticity in relation to the demand of the pulp, differentiated for country oforigin. The model considers that imports are differentiated by origin; therefore they are not perfect substitutes. The demand from Europe, North America and the Rest of the World for the pulp from theUnited States,Canada, Sweden, Finland, Portugal and Brazil was inelastic. The Asian demand for thissome pulp was elastic. Europe and the Rest of the World showed negative cross-price elasticity, i. e.,and the imported pulp from other countries are complementary products. North America and Asiashowed positive crow-price elasticity, i. e., they consider the pulp produced in other countries assubstitute products. The net effect of the variation on the price of pulp in a country h, over the amountof pulp that goes to the region i depends on the matching of values related to the elasticity ofsubstitution and the price elasticity of the total demand.

    The Distributed Generation Market Demand model (dGen) is a geospatially rich, bottom-up, market-penetration model that simulates the potential adoption of distributed energy resources (DERs) for residential, commercial, and industrial entities in the continental United States through 2050. The National Renewable Energy Laboratory (NREL) developed dGen to analyze the key factors that will affect future market demand for distributed solar, wind, storage, and other DER technologies in the United States. The new model builds off, extends, and replaces NREL's SolarDS model (Denholm et al. 2009a), which simulates the market penetration of distributed PV only. Unlike the SolarDS model, dGen can model various DER technologies under one platform--it currently can simulate the adoption of distributed solar (the dSolar module) and distributed wind (the dWind module) and link with the ReEDS capacity expansion model (Appendix C). The underlying algorithms and datasets in dGen, which improve the representation of customer decision making as well as the spatial resolution of analyses (Figure ES-1), also are improvements over SolarDS.

    The degree to which any deregulated market functions efficiently often depends on the ability of market agents to respond quickly to fluctuating conditions. Many restructured electricity markets, however, experience high prices caused by supply shortages and little demand-side response. We examine the implications for market operations when a risk-averse retailer's end-use consumers are allowed to perceive real-time variations in the electricity spot price.

    This report provides an analysis of uranium supply and demand under the current conditions of this developing global market. While an analysis is possible, it should be borne in mind that available information is not always complete under conditions of major reorganization, and consequently some speculative assessment is required. Therefore, although this article is based on the latest information available, it should be considered as background material for further analysis rather than as an accurate forecast for the future. The level of uncertainty is particularly high regarding the future availability of nuclear materials produced in newly independent States emerging from the former Soviet Union

    Current power distribution systems are operated in a top-down manner. Power production control and price formation take place on a central level on the basis of relatively static data from a data collection and dispatching network with a limited scope and granularity. When incorporating a more considerable fraction of small-scale producers on the basis of, for instance, renewable energy, operation of the distribution grid requires more data to be collected from a more extensive information and data communication network. Furthermore, increased local flows, in the form of two-way communication with distributed computation techniques, enable a more dynamic adaptation in power supply and demand patterns paving the way to a flexible way of embedding of ill-predictable supply of some types of renewable energy sources. DSM-programs have been in use in the utility sector for years now. In this document, first, current Demand Side Management (DSM) and Demand Response Resource (DRR) techniques are discussed; then, supply side management especially in a DG (Distributed Generation) context is treated. A framework of novel concepts and possible technology directions is presented subsequently and some preliminary scenarios are shown to illustrate these concepts. An overview of more flexible supply and demand matching schemes is given essentially based on four distinct types of SDM clusters. It appears, that it is possible to fulfil requirements for these distributed environments in terms of needed information and communication technology, ICT, if these are paralleled with the expected future penetration of ever-smaller scale data-exchange networks at power customer sites. Agent technology using algorithms from micro-economic market theory offers a promising possibility for managing the complexity of price formation and supply demand matching in these fine-grained bottom-up control distribution networks. Implication of these technical developments in terms of market and business

  3. Market-based demand forecasting promotes informed strategic financial planning.

    Science.gov (United States)

    Beech, A J

    2001-11-01

    Market-based demand forecasting is a method of estimating future demand for a healthcare organization's services by using a broad range of data that describe the nature of demand within the organization's service area. Such data include the primary and secondary service areas, the service-area populations by various demographic groupings, discharge utilization rates, market size, and market share by service line and organizationwide. Based on observable market dynamics, strategic planners can make a variety of explicit assumptions about future trends regarding these data to develop scenarios describing potential future demand. Financial planners then can evaluate each scenario to determine its potential effect on selected financial and operational measures, such as operating margin, days cash on hand, and debt-service coverage, and develop a strategic financial plan that covers a range of contingencies.

It is possible that a product or service is no longer required when it is available, even if the need is there, but wishes have undergone some changes and the image of the product on which a buyer wants is another. A buyer may be satisfied when the ownership of a product but be disappointed in the performance of its actual time of use. That is why we have made a distinction between objective and subjective value. Objective value , addressing the needs , provides a degree of satisfaction dependent on characteristics of age, gender, origin, vocational, family specifically. Subjective value is determined by the degree of satisfaction of desires , and is appreciated by each buyer depending on habits , cultural and social group consumption and education. There are four ways to approach that emphasizes differentiation: new products (differentiation, better products (positioning, faster products sold (focusing and cheaper products (cost leadership.

    The National Renewable Energy Laboratory (NREL) developed the Distributed Geothermal Market Demand Model (dGeo) as a tool to explore the potential role of geothermal distributed energy resources (DERs) in meeting thermal energy demands in the United States. The dGeo model simulates the potential for deployment of geothermal DERs in the residential and commercial sectors of the continental United States for two specific technologies: ground-source heat pumps (GHP) and geothermal direct use (DU) for district heating. To quantify the opportunity space for these technologies, dGeo leverages a highly resolved geospatial database and robust bottom-up, agent-based modeling framework. This design is consistent with others in the family of Distributed Generation Market Demand models (dGen; Sigrin et al. 2016), including the Distributed Solar Market Demand (dSolar) and Distributed Wind Market Demand (dWind) models. dGeo is intended to serve as a long-term scenario-modeling tool. It has the capability to simulate the technical potential, economic potential, market potential, and technology deployment of GHP and DU through the year 2050 under a variety of user-defined input scenarios. Through these capabilities, dGeo can provide substantial analytical value to various stakeholders interested in exploring the effects of various techno-economic, macroeconomic, financial, and policy factors related to the opportunity for GHP and DU in the United States. This report documents the dGeo modeling design, methodology, assumptions, and capabilities.

  13. Bayesian Analysis of Demand Elasticity in the Italian Electricity Market

    Full Text Available The liberalization of the Italian electricity market is a decade old. Within these last ten years, the supply side has been extensively analyzed, but not the demand side. The aim of this paper is to provide a new method for estimation of the demand elasticity, based on Bayesian methods applied to the Italian electricity market. We used individual demand bids data in the day-ahead market in the Italian Power Exchange (IPEX, for 2011, in order to construct an aggregate demand function at the hourly level. We took into account the existence of both elastic and inelastic bidders on the demand side. The empirical results show that elasticity varies significantly during the day and across periods of the year. In addition, the elasticity hourly distribution is clearly skewed and more so in the daily hours. The Bayesian method is a useful tool for policy-making, insofar as the regulator can start with a priori historical information on market behavior and estimate actual market outcomes in response to new policy actions.

    The degree to which any deregulated market functions efficiently often depends on the ability of market agents to respond quickly to fluctuating conditions. Many restructured electricity markets, however, experience high prices caused by supply shortages and little demand-side response. We examine the implications for market operations when a risk-averse retailer's end-use consumers are allowed to perceive real-time variations in the electricity spot price. Using a market-equilibrium model, we find that price elasticity both increases the retailers revenue risk exposure and decreases the spot price. Since the latter induces the retailer to reduce forward electricity purchases, while the former has the opposite effect, the overall impact of price responsive demand on the relative magnitudes of its risk exposure and end-user price elasticity. Nevertheless, price elasticity decreases cumulative electricity consumption. By extending the analysis to allow for early settlement of demand, we find that forward stage end-user price responsiveness decreases the electricity forward price relative to the case with price-elastic demand only in real time. Moreover, we find that only if forward stage end-user demand is price elastic will the equilibrium electricity forward price be reduced.

  15. A Supply and Demand Update of the Molybdenum-99 Market

    International Nuclear Information System (INIS)

    2012-08-01

    Medical diagnostic imaging techniques using technetium-99m account for roughly 80% of all nuclear medicine procedures, representing over 30 million examinations worldwide every year. Disruptions in the supply chain of these medical isotopes - which have half-lives of 66 hours for molybdenum-99 ( 99 Mo) and 6 hours for its daughter isotope, technetium-99m (' 99m Tc), and thus must be produced continually - can lead to cancellations or delays in important medical testing services. Unfortunately, supply reliability has declined over the past decade due to unexpected or extended shutdowns at the few ageing 99 Mo-producing research reactor and processing facilities. These shutdowns have created global supply shortages. In 2011, the OECD Nuclear Energy Agency (NEA), along with its High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR), released a report that presents the reasons behind the lack of infrastructure that led to global supply shortages and a policy approach to encourage long-term medical isotope supply security. In that report, The Supply of Medical Radioisotopes: The Path to Reliability, the NEA also provides potential futures of supply and demand out to 2030. Since the release of The Path there have been a number of changes in the market and therefore this document provides an update on the 2011 supply and demand situation. This update is based on information provided to the NEA by members of the HLG-MR and other key stakeholders. This presentation of supply and demand future scenarios for the 99 Mo market revises previous NEA future scenarios based on new data and target conversion commitments from the supply chain. The update, unfortunately, does not present a more optimistic future scenario than previous presentations - the concern around the uneconomic situation of the supply chain continues to dominate the potential for new projects. This results in the potential for long-term shortages within the decade. However, there are a

    Highlights: • Analyze the impact of a demand response program under uncertainty. • Stochastic Nash–Cournot competition model is formulated. • Case study of the Taiwanese electric power market is conducted. • Demand response decreases power price, generation, and emissions. • Demand uncertainty increases energy price and supply risk in the results. - Abstract: In the electricity market, demand response programs are designed to shift peak demand and enhance system reliability. A demand response program can reduce peak energy demand, power transmission congestion, or high energy-price conditions by changing consumption patterns. The purpose of this research is to analyze the impact of a demand response program in the energy market, under demand uncertainty. A stochastic–multiobjective Nash–Cournot competition model is formulated to simulate demand response in an uncertain energy market. Then, Karush–Kuhn–Tucker optimality conditions and a linear complementarity problem are derived for the stochastic Nash–Cournot model. Accordingly, the linear complementarity problem is solved and its stochastic market equilibrium solution is determined by using a general algebraic modeling system. Additionally, the case of the Taiwanese electric power market is taken up here, and the results show that a demand response program is capable of reducing peak energy consumption, energy price, and carbon dioxide emissions. The results show that demand response program decreases electricity price by 2–10%, total electricity generation by 0.5–2%, and carbon dioxide emissions by 0.5–2.5% in the Taiwanese power market. In the simulation, demand uncertainty leads to an 2–7% increase in energy price and supply risk in the market. Additionally, tradeoffs between cost and carbon dioxide emissions are presented.

  17. Demand response in experimental electricity markets

    2012-03-01

    Full Text Available We study consumers’ behavior in an experimental electricity market. Subjects make decisions concerning the quantity of electric energy they want to consume in three different pricing environments. In the baseline framework, they decide under a system of fixed prices, invariant to consumption schedule as well as to network restrictions. The other two environments correspond to dynamic pricing systems combined with incentives that aim at cutting energy consumption in a number of selected situations characterized by high network congestion. In such situations, in the first environment subjects get a bonus if they reduce their peak consumption below a certain level, while in the second one, consumers are sanctioned for consuming in peak times. From a social welfare perspective, our experimental data confirm that a dynamic system for prices is more efficient than a fixed one. Moreover, a dynamic scheme with sanctions, although less preferred by consumers, is more effective than the one with bonuses in order to reduce peak consumption. Dynamic pricing with bonuses reaches a good balance between efficiency and consumer acceptance.

    Estudiamos el comportamiento de los consumidores en un mercado de electricidad diseñado en el laboratorio. Los sujetos experimentales toman decisiones sobre la cantidad de electricidad que desean consumir en tres contextos diferentes. En el tratamiento base, los consumidores deciden bajo un sistema de precios fijos, en el que el precio es invariable tanto a la franja horaria de consumo como a las restricciones de la red. Los otros dos contextos corresponden a sistemas dinámicos de precios combinados con incentivos cuyo objetivo es la reducción del consumo en algunas situaciones seleccionadas caracterizadas por una alta congestión de la red. En estas situaciones, en el primer contexto, se bonifica la reducción del consumo en la hora punta por debajo de cierto nivel, mientras que en el segundo, los consumidores

    2010-01-01

    Uncertainty in the electrical energy market is expected to increase with growth in the percentage of generation using renewable resources. Demand response can play a key role in giving stability to system operation. This paper discusses the embedded generation for industrial demand response in renewable energy markets. The methodology of the demand response is explained. It consists of long-term optimization and stochastic optimization. Wind energy, among all the renewable resources, is becoming increasingly popular. Volatility in the wind energy sector is high and this is explained using examples. Uncertainty in the wind market is shown using stochastic optimization. Alternative techniques for generation of wind energy were seen to be needed. Embedded generation techniques include co-generation (CHP) and pump storage among others. These techniques are analyzed and the results are presented. From these results, it is seen that investment in renewables is immediately required and that innovative generation technologies are also required over the long-term.

    The trade in wildlife products can represent an important source of income for poor people, but also threaten wildlife locally, regionally and internationally. Bushmeat provides livelihoods for hunters, traders and sellers, protein to rural and urban consumers, and has depleted the populations of many tropical forest species. Management interventions can be targeted towards the consumers or suppliers of wildlife products. There has been a general assumption in the bushmeat literature that the urban trade is driven by consumer demand with hunters simply fulfilling this demand. Using the urban bushmeat trade in the city of Kumasi, Ghana, as a case study, we use a range of datasets to explore the processes driving the urban bushmeat trade. We characterise the nature of supply and demand by explicitly considering three market attributes: resource condition, hunter behaviour, and consumer behaviour. Our results suggest that bushmeat resources around Kumasi are becoming increasingly depleted and are unable to meet demand, that hunters move in and out of the trade independently of price signals generated by the market, and that, for the Kumasi bushmeat system, consumption levels are driven not by consumer choice but by shortfalls in supply and consequent price responses. Together, these results indicate that supply-side processes dominate the urban bushmeat trade in Kumasi. This suggests that future management interventions should focus on changing hunter behaviour, although complementary interventions targeting consumer demand are also likely to be necessary in the long term. Our approach represents a structured and repeatable method to assessing market dynamics in information-poor systems. The findings serve as a caution against assuming that wildlife markets are demand driven, and highlight the value of characterising market dynamics to inform appropriate management. PMID:27632169

    Demand response plays an important role in maintaining the economic stability of the system, and has the characteristics of high efficiency, low cost, fast response, good environmental benefits and so on. Demand side resource is an important part of electricity market. The research of demand side resources in our country is still in the initial stage, but the opening of the electricity sales side provides a broad prospect for the development of electricity market. This paper summarizes the main types of demand side resources in our country, analyzes the economic principle of demand response from the micro perspective, puts forward some suggestions on the operation mechanism of China’s demand side resources participating in the electricity market under the condition of electricity sales side opening, analyzes the current situation of pricing in the electricity wholesale market and sets up the pricing strategy of the centralized wholesale market with the demand side power supply participating in quotation, which makes the social and economic benefits reach the maximum.

    1994-06-01

    This document looks at the supply of and demand for uranium on markets worldwide and covers the years 1992 to 2010. Uranium and nuclear fuel markets have become truly global with the inclusion of fuel cycle companies from Eastern Europe and the Commonwealth of Independent States (CIS) leading at the same time to additional supplies becoming available and new political constraints on uranium trading. This report includes new data from China, Eastern Europe and the CIS republics. As recycling plays on ever more important role, the global supply and demand balance for uranium and fuel services is altered. Prospects for nuclear power growth and for the uranium market in the next century remain uncertain. (UK)

    Bjoerndal, Mette; Lund, Arne-Christian; Rud, Linda

    2005-01-01

    The liberalization of the Nordic electricity markets started with the deregulation of the Norwegian market, and the later inclusion of Sweden, Denmark and Finland in The Nord Pool area has provided a truly international marketplace, where prices are quoted for all the Nordic countries except Iceland. The structure of the Norwegian supply side was a favorable starting point for the liberalization process with many independent (hydropower) producers and, following the Energy Act of 1991, the vertical separation of competitive production on the one hand and regulated transmission / distribution one the other hand (implemented as a requirement of separation of financial accounts). Moreover, since the mid 1990s (unregulated) retail competition has provided market based price-signals to customers, even to individual households. In this paper we will focus on the potential benefits of demand flexibility in order to enhance the performance of the electricity market in attaining optimal operation and development of the electricity system. These benefits will depend on the price elasticity of the demand. However, whether it is possible to act on price changes also depends on the information provided to and from the customers. Especially for short run flexibility, this may require two way communication devises for larger customer groups, which raises questions like who is to pay for the investments needed, and who will benefit from them. Demand response also depends on the marginal signals resulting from the different contracts offered to the customers. Today this includes ''variable'' price, spot price (based on Nord Pool Elspot) and fixed price contracts. Customer flexibility depends on the possibility of substitution for instance to other fuels / alternative energy provisions. Finally, flexibility will differ between customer classes, for instance households, industry, power intensive industry etc. In this paper we investigate demand response and customer flexibility in

    2016-07-01

    Full Text Available Knowledge of the distribution of consumer buying strategies by producers may permit improved marketing strategies and improved ability to respond to volatile market conditions. In order to investigate potential ways of gaining such knowledge, this study extends the work of Kahneman, Russell, and Thaler through the application of a probabilistic demand framework using Choice Wave theory, based on the Schrödinger Wave Equation in quantum mechanics. Probabilistic variability of response to health information and its potential influence on buying strategies is also investigated, extending the work of Clement, Johnson, Hu, Pagoulatos, and Debertin. In the present study, the domestic cracker market within fourteen U.S. metropolitan areas is segmented, using the Choice Wave Probabilistic Demand approach, into two statistically independent “Consumer Types” of seven metropolitan areas each. The two Consumer Types are shown to have statistically different elasticities than each other and from the combined market as a whole. This approach may provide not only improved marketing strategies through improved awareness of consumer preferences and buying strategies, especially in the volatile agricultural sector, but also may be useful in aiding producers of store brand/private label products in finding desirable markets in which to compete against national brands. The results also suggest that supply/producer-side strategies should take into account the ways in which information, whether under the direct control of the producer or not, may influence and change consumer buying strategies.

  6. The role of price elastic demand in market power in the Nordic electricity markets

    International Nuclear Information System (INIS)

    Ravn, H.F.

    2004-01-01

    The paper discusses the modelling and analysis of market power and price elastic demand in the Nordic electricity spot market, Nordpool. The modelling of market power in the electricity sector must take into account a number of features that are specific to the electricity sector. First, electricity cannot be stored, but must be produced simultaneously with consumption. This aspect is, however, modified by the possibility of using hydro reservoirs as an indirect electricity storage. Second, the electricity transmission network plays an important role by breaking the market into several geographically separate sub-markets with different prices. Moreover, the specific bottlenecks may differ from hour to hour, according to the balance between supply and demand in each sub-market. Third, the demand side is presently characterised by very limited experience with hour to-hour-changes in electricity prices and very limited experience with short time adjustments of electricity consumption in response to changes in the electricity price. In the present paper three basic models for supply side competition on the Nordpool spot market will be presented, viz., perfect competition, Cournot competition and Supply Function Equilibrium. The models represent price and quantity settlement, including determination of price areas (bottle necks), in accordance with the way the Nordpool market functions. The models will incorporate electricity demand which is responsive to the electricity price. The paper describes the role of demand response for the determination of the electricity prices in each of the three supply side competition models. (au)

    International Nuclear Information System (INIS)

    2003-01-01

    Highly volatile electricity prices are becoming a more frequent and unwanted characteristic of modern electricity wholesale markets. But low demand elasticity, mainly the result of a lack of incentives and consumers' inability to control demand, means that consumer behaviour is not reflected in the cost of energy. This study analyses the impact of price-responsive demand and shows how pricing, policy and technology can be used to inform consumer behaviour and choice. Informed choice and market-based valuation of electricity supply will ensure liberalized markets are competitive, efficient, less volatile and able to provide long term security of supply. Significant benefits will occur even if only 5% of customers become responsive to price-incentives and information. And customers will respond to well designed programs, thereby developing a role in ensuring efficient price formulation for electricity. This study analyses the economic, efficiency and security benefits and identifies the changes in electricity tariffs and the network infrastructure needed to achieve greater demand response

    Due to characteristics of the power system, costs of producing electricity vary considerably over short time intervals. Yet, many consumers do not experience corresponding variations in the price they pay for consuming electricity. The topic of this report is: are consumers willing and able to respond to short-term variations in electricity prices, and if so, what is the social benefit of consumers doing so? Taking Denmark and the Nord Pool market as a case, the report focuses on what is known as short-term consumer flexibility or demand response in the electricity market. With focus on market efficiency, efficient allocation of resources and security of supply, the report describes demand response from a micro-economic perspective and provides empirical observations and case studies. The report aims at evaluating benefits from demand response. However, only elements contributing to an overall value are presented. In addition, the analyses are limited to benefits for society, and costs of obtaining demand response are not considered. (au)

    Since 2006, the petroleum industry has been interested in collaboration to determine labour demand and supply/demand gaps for the upstream petroleum industry. In 2006, the petroleum industry experienced strong employment growth and was having difficulty finding workers. Comprehensive, up-to-date labour market information and analysis are the key foundation for addressing labour supply/demand issues. This document presented labour market information on the petroleum industry in order to inform company retention and recruitment offices; government departments involved in development of labour market policies and programs; education and training institutions; guidance counsellors, employment centres and organizations that work with youth and labour supply pools; and job seekers. Specific topics that were discussed included two industry scenarios (growth and base case) in determining the petroleum industry's medium-and long-term employment needs; labour supply/demand considerations for the industry as a whole and an industry-wide cost management; and an analysis of exploration and production, oil sands, services, and pipeline sectors to 2020. It was concluded that while new employment is not expected to lead to labour shortages within the pipeline sector, attrition due to requirements almost certainly would. In the growth scenario, it is likely the pipeline sector will be challenged by competition from the other petroleum industry sectors. tabs., figs., appendices.

    Atkins, F.; Tayyebi Jazayeri, S.M.

    2004-04-01

    The literature on world oil market demands was reviewed, summarized and organized into seven major groupings. The objective was to model economic behaviour before and after price shocks. In particular, the paper demonstrated how the price elasticity of demand in world oil markets is estimated. It also showed how the relationship between energy and oil consumption and income are estimated. The income elasticity of demand was also estimated, and empirical estimates of the elasticity of aggregate output regarding crude oil and energy prices were presented. The paper also referred to the transportation sector and estimates of the changing nature of seasonal factors. The review showed that there is much heterogeneity of econometric results. The literature showed that demand increased considerably in response to the price shocks of the 1970s, but these shocks were reversed in the 1980s when the increase in demand did not correspond with the decrease in price. Some of the literature is driven by the belief that there must be a stable, non-linear model that fits the data both before and after price shocks. The authors question whether this could be true and propose an alternative hypothesis that there is a different model that pertains to economic behaviour after price shocks. 15 refs., 7 tabs., 1 fig

    2010-01-01

    Empirical evidence concerning demand response (DR) resources is needed in order to establish baseline conditions, develop standardized methods to assess DR availability and performance, and to build confidence among policymakers, utilities, system operators, and stakeholders that DR resources do offer a viable, cost-effective alternative to supply-side investments. This paper summarizes the existing contribution of DR resources in U.S. electric power markets. In 2008, customers enrolled in existing wholesale and retail DR programs were capable of providing ∝38,000 MW of potential peak load reductions in the United States. Participants in organized wholesale market DR programs, though, have historically overestimated their likely performance during declared curtailments events, but appear to be getting better as they and their agents gain experience. In places with less developed organized wholesale market DR programs, utilities are learning how to create more flexible DR resources by adapting legacy load management programs to fit into existing wholesale market constructs. Overall, the development of open and organized wholesale markets coupled with direct policy support by the Federal Energy Regulatory Commission has facilitated new entry by curtailment service providers, which has likely expanded the demand response industry and led to product and service innovation.

    Stock price prediction is an important and challenging problem in stock market analysis. Existing prediction methods either exploit autocorrelation of stock price and its correlation with the supply and demand of stock, or explore predictive indictors exogenous to stock market. In this paper, using transaction record of stocks with identifier of traders, we introduce an index to characterize market confidence, i.e., the ratio of the number of traders who is active in two successive trading days to the number of active traders in a certain trading day. Strong Granger causality is found between the index of market confidence and stock price. We further predict stock price by incorporating the index of market confidence into a neural network based on time series of stock price. Experimental results on 50 stocks in two Chinese Stock Exchanges demonstrate that the accuracy of stock price prediction is significantly improved by the inclusion of the market confidence index. This study sheds light on using cross-day trading behavior to characterize market confidence and to predict stock price.

    System security in electricity markets relies crucially on the interaction between demand and supply over time. However, research on electricity markets has been mainly focusing on the supply side arguing that demand is rather inelastic. Assuming perfectly inelastic demand might lead to delusive statements regarding the price formation in electricity markets.

    International Nuclear Information System (INIS)

    Holder, J.

    1998-01-01

    The issue of the energy market's ability to support pipeline expansion projects was discussed. Pipeline expansion is a natural corollary of deregulation. Since expansion and competition in the natural gas industry go hand in hand, pipeline expansion is inevitable, imperative and in the longer-term is in the best interest of the end use gas consumer. The effect of pipeline expansion on local distribution companies (LDCs) such as Consumers Gas which serves eastern Canadian markets was also described. It was explained that LDCs are being transformed by deregulation which has opened the market to direct purchasing, meaning that end-users (including residential customers) can buy their natural gas through various brokers, marketers and producers. Some of the other factors affecting the demand for natural gas such as convergence, deregulation, the environment, and their impact were also discussed. It was suggested that in the near-term there is a possibility of over-construction of pipeline capacity, resulting in the demise of some of the projects. Even in the longer-term, only the pipelines that are willing to differentiate themselves from other pipelines by providing more customer choice, more service options and better service, will prosper. Market and regulatory advantage can also be gained by quickly reacting to changing market conditions through expansion of existing pipelines in stages via compression and looping. In pipeline construction timing is critical

    There has been attention on the job market recently and on radiology's supply/demand calculus. Supply is influenced by the number of trained radiologists, while demand is driven by demographics and technological innovation. We analyze the supply of radiologists historically and compare to other labor markets-medical and non-medical, domestic and foreign. We review National Resident Matching Program data in radiology and several other specialties from 1991 to 2015. We also review surveys, physician recruitment data, and peer-reviewed commentaries on medical specialty job markets. Trends are compared across specialties. The regulation of American medical training is compared to that in the United Kingdom and to a nonmedical labor market, unionized theatrical stage employees. Radiology residency positions have increased since 1998 despite a downturn in the job market. This expansion coincides with a decreasing percentage of positions filled by domestic graduates. A similar trend has been seen in pathology, a notoriously oversupplied specialty. Conversely, other specialties have maintained their proportion of domestic graduates by way of limited supply or implicit demand. The radiology job market is currently oversupplied, primarily a result of increasing residency positions despite indicators of decreasing demand. The percentage of residency positions filled by domestic graduates has decreased during the same period, suggesting that medical student interest is responsive to the market. Other specialties, particularly pathology, demonstrate the dangers of chronic oversupply. We advocate a reduction of radiology residency positions such that supply closely approximates demand without exceeding it. Additional measures may be taken, if necessary, to restore market equilibrium in the event of a mild undersupply. Copyright © 2015 The Association of University Radiologists.

  6. Accelerating residential PV expansion: demand analysis for competitive electricity markets

    International Nuclear Information System (INIS)

    Duke, Richard; Williams, Robert; Payne, Adam

    2005-01-01

    This article quantifies the potential market for grid-connected, residential photovoltaic (PV) electricity integrated into new homes built in the US. It complements an earlier supply-side analysis by the authors that demonstrates the potential to reduce PV module prices below $1.5/W p by scaling up existing thin-film technology in 100 MW p /yr manufacturing facilities. The present article demonstrates that, at that price, PV modules may be cost effective in 125,000 new home installations per year (0.5 GW p /yr). While this market is large enough to support multiple scaled up thin-film PV factories, inefficient energy pricing and demand-side market failures will inhibit prospective PV consumers without strong public policy support. Net metering rules, already implemented in many states to encourage PV market launch, represent a crude but reasonable surrogate for efficient electricity pricing mechanisms that may ultimately emerge to internalize the externality benefits of PV. These public benefits include reduced air pollution damages (estimated costs of damage to human health from fossil fuel power plants are presented in Appendix A), deferral of transmission and distribution capital expenditures, reduced exposure to fossil fuel price risks, and increased electricity system reliability for end users. Thus, net metering for PV ought to be implemented as broadly as possible and sustained until efficient pricing is in place. Complementary PV 'buydowns' (e.g., a renewable portfolio standard with a specific PV requirement) are needed to jumpstart regional PV markets

    Demand response has grown to be a part of the repertoire of resources used by utilities to manage the balance between generation and load. In recent years, advances in communications and control technology have enabled utilities to consider continuously controlling demand response to meet generation, rather than the other way around. This paper discusses the economic applications of a general method for load resource analysis that parallels the approach used to analyze generation resources and uses the method to examine the results of the US Department of Energy’s Olympic Peninsula Demonstration Testbed. A market-based closed-loop system of controllable assets is discussed with necessary and sufficient conditions on system controllability, observability and stability derived.

    2015-06-01

    This paper presents a generalized formulation of Demand Response (DR) under deregulated electricity markets. The problem is scheduling and controls the consumption of electrical loads according to the market price to minimize the energy cost over a day. Taking into account the modeling of customers' comfort (i.e., preference), the formulation can be applied to various types of loads including what was traditionally classified as critical loads (e.g., air conditioning, lights). The proposed DR scheme is based on Dynamic Programming (DP) framework and solved by DP backward algorithm in which the stochastic optimization is used to treat the uncertainty, if any occurred in the problem. The proposed formulation is examined with the DR problem of different loads, including Heat Ventilation and Air Conditioning (HVAC), Electric Vehicles (EVs) and a newly DR on the water supply systems of commercial buildings. The result of simulation shows significant saving can be achieved in comparison with their traditional (On/Off) scheme.

    Demand Response (DR) has been extensively developed and implemented in the US and Europe. However, DR hardly exists in many developing countries for similar problems such as rigid power market and state monopoly. With the increasing imbalance between supply and demand in China's power industry, the government has issued new policies on DR and approved the first batch of pilot cities. China is setting a good example of how to encourage DR under monopolistic electric market and open up the market to aggregators and DR suppliers. This paper summarizes the current DR status, feasible DR market schemes and DR pilot projects in China. First, electric power system reform, renewable energy policies and power industry development are reviewed, highlighting the problems associated with the current dispatch mechanisms of DR policies and markets. New DR programs and DR-related policies are also introduced. On this basis, the driving forces and challenges associated with DR in China are analyzed. The major challenge is the lack of a suitable market mechanism for the current Chinese power industry. Hence, this paper presents six feasible strategies that fully utilize the existing policies. Additionally, the latest DR applications in different pilot cities are summarized and analyzed. - Highlights: • Summarize the status, feasible market schemes and pilot projects of DR in China. • Highlight the problems of the current dispatch mechanisms of DR policies and market. • Analyze the driving forces and challenges associated with DR in China. • Present six feasible strategies that fully utilize the existing policies. • Summarize and analyze the latest DR applications in different pilot cities.

    2002-01-01

    Chicago and its suburbs are experiencing an increasing demand for water from a growing population and economy and may experience water scarcity in the near future. The Chicago metropolitan area has nearly depleted its groundwater resources to a point where interstate conflicts with Wisconsin could accompany an increased reliance on those sources. Further, the withdrawals from Lake Michigan is limited by the Supreme Court decree. The growing demand and indications of possible scarcity suggest a need to reexamine the pricing policies and the dynamics of demand. The study analyses the demand for water and develops estimates of scarcity rents for water in Chicago. The price and income elasticities computed at the means are -0.002 and 0.0002 respectively. The estimated scarcity rents ranges from $0.98 to $1.17 per thousand gallons. The results indicate that the current prices do not fully account for the scarcity rents and suggest a current rate with in the range $1.53 to $1.72 per thousand gallons.

    2010-01-01

    Does an electricity market which has been restructured to foster competition provide greater opportunities for demand response than a traditional regulated utility industry? The experiences of the restructured Electric Reliability Council of Texas (ERCOT) market over the past eight years provide some hope that it is possible to design a competitive market which will properly value and accommodate demand response. While the overall level of demand response in ERCOT is below the levels enjoyed prior to restructuring, there have nonetheless been some promising advances, including the integration of demand-side resources into competitive markets for ancillary services. ERCOT's experiences demonstrate that the degree of demand participation in a restructured market is highly sensitive to the market design. But even in a market which has been deregulated to a large degree, regulatory intervention and special demand-side programs may be needed in order to bolster demand response. (author)

    2010-01-01

    One of the responsibilities of power market regulator is setting rules for selecting and prioritizing demand response (DR) programs. There are many different alternatives of DR programs for improving load profile characteristics and achieving customers' satisfaction. Regulator should find the optimal solution which reflects the perspectives of each DR stakeholder. Multi Attribute Decision Making (MADM) is a proper method for handling such optimization problems. In this paper, an extended responsive load economic model is developed. The model is based on price elasticity and customer benefit function. Prioritizing of DR programs can be realized by means of Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Considerations of ISO/utility/customer regarding the weighting of attributes are encountered by entropy method. An Analytical Hierarchy Process (AHP) is used for selecting the most effective DR program. Numerical studies are conducted on the load curve of the Iranian power grid in 2007. (author)

    Turkey's Energy Efficiency Law (EEL), enacted in 2007, had been expected to transform the energy policies in government and private sectors, and offer opportunities for, then-impending, Turkish Energy Service Company (ESCO) market. Yet, the communiqué of the EEL related to ESCOs was released only recently in July 2012. In this work, we review the current status of the ESCO market in Turkey. We provide an outlook through the recent legal communiqué and present barriers, enabling factors, and opportunities, supported by country's financial and economic facts. ESCO-financing mechanism prevailing and the sources of financing in the country are also mentioned. The communiqué on ESCOs fits well in the chain of regulatory attempts to increase Turkey's competitiveness in the global markets. However, we anticipate that some of its principles and procedures to be enforced may be deterrent for small-scale candidate ESCOs and may slow down the expected development of the Turkish ESCO market. Otherwise, the communiqué should lead restructuring of a stronger ESCO market in Turkey. - Highlights: • We review the current status of the ESCO market in Turkey. • We give outlook through the recent communiqué on ESCOs. • We provide view through financial and economic facts. • We present barriers, enabling factors, and suggestions

    An important discussion in later years has been whether the necessary reserves in the electricity market are to be generated through normal market mechanisms, i.e. with the price as the primary controlling parameter, or if it requires a collectively financed capacity reserve and how regulations in such a case should be shaped. The issue is first and foremost a matter of where the line is drawn between that which 'the market' should handle and that which can be assured through regulation. Autumn 2002 Svenska Kraftnaet (the Swedish TSO) presented an investigation to the government in which it was suggested that the capacity balance should primarily be managed through the use of normal pricing mechanisms, but that the state should strengthen responsibility for the nation's capacity balance in the period up until 2008. When approaching an effect loss situation, spot prices and balancing power prices will skyrocket. Today, most people are in agreement that a condition for maintained delivery safety is that normal pricing mechanisms are in place and that consumption actually is affected by high prices. The main reason for this conclusion is that it is very expensive to keep production facilities in reserve for situations that are expected to occur very seldom - it is cheaper to encourage large customers to reduce their consumption. The other reason is that increased price sensitivity creates conditions for a more stable and more predictable pricing development in strained situations. While being aware that a response to increased demand is needed, we see too little of that on the market today. The aim of this project is to present concrete measures that will awaken this slumbering resource. In order to judge how much demand response that can reasonably be expected and if there is any financial gain for customers, electricity suppliers and grid operators; it has been necessary to cast a few predictions about future price peaks. We estimate price peaks in the 3-10 SEK

    Full Text Available This paper analyzes the demand for shrimp along with beef, pork, and chicken in the US food market, which contributes much to predicting supply strategies, consumer preferences and policy making. It focuses on the own and cross elasticity relationship between the expenditure share, price, and expenditure changes. An Almost Ideal Demand System (AIDs model and two alternative specifications (both nonlinear AIDs and LA-AIDs are used to estimate a system of expenditure share equations for ocean shrimp, penaeid shrimp, beef, pork, and chicken. Empirical results from nonlinear AIDs model is compared with those from LA-AIDs model. There are quite a few inconsistency between nonlinear and LA results. Results from nonlinear are more expected and more complied with microeconomic theory than those from LA. Also, results indicated that some insignificant slope coefficients and inappropriate signs of them did not comply with microeconomic theory. This could be caused by heteroscedasticity, autocorrelation, a limitation in the data used, or shrimp is a quite different commodity.

    The Organization of Midwest ISO States (OMS) launched the Midwest Demand Resource Initiative (MWDRI) in 2007 to identify barriers to deploying demand response (DR) resources in the Midwest Independent System Operator (MISO) region and develop policies to overcome them. The MWDRI stakeholders decided that a useful initial activity would be to develop more detailed information on existing retail DR programs and dynamic pricing tariffs, program rules, and utility operating practices. This additional detail could then be used to assess any"seams issues" affecting coordination and integration of retail DR resources with MISO's wholesale markets. Working with state regulatory agencies, we conducted a detailed survey of existing DR programs, dynamic pricing tariffs, and their features in MISO states. Utilities were asked to provide information on advance notice requirements to customers, operational triggers used to call events (e.g. system emergencies, market conditions, local emergencies), use of these DR resources to meet planning reserves requirements, DR resource availability (e.g., seasonal, annual), participant incentive structures, and monitoring and verification (M&V) protocols. This report describes the results of this comprehensive survey and discusses policy implications for integrating legacy retail DR programs and dynamic pricing tariffs into organized wholesale markets. Survey responses from 37 MISO members and 4 non-members provided information on 141 DR programs and dynamic pricing tariffs with a peak load reduction potential of 4,727 MW of retail DR resource. Major findings of this study area:- About 72percent of available DR is from interruptible rate tariffs offered to large commercial and industrial customers, while direct load control (DLC) programs account for ~;;18percent. Almost 90percent of the DR resources included in this survey are provided by investor-owned utilities. - Approximately, 90percent of the DR resources are available with less than

    2011-01-01

    Denmark, east and west of the Great Belt are bidding areas with separate hourly area prices for the Nord Pool power exchange, covering four Nordic countries and parts of Germany. The share of wind power has now increased to 25% on an annual basis in western Denmark. This has a significant impact not only on the electricity wholesale prices, but also on the development of the market. Hourly market data are available from the website of Danish TSO from 1999. In this paper these data are analysed for the period 2004–2010. Electricity generators and customers may respond to hourly price variations, which can improve market efficiency, and a welfare gain is obtained. An important limitation for demand response is events of several consecutive hours with extreme values. The analysis in this paper is a summary and update of some of the issues covered by the EU RESPOND project. It shows that extreme events were few, and the current infrastructure and market organisation have been able to handle the amount of wind power installed so far. This recommends that geographical bidding area for the wholesale electricity market reflects external transmission constraints caused by wind power. - Highlights: ► More than 10 years of hourly electricity market data are available for western Denmark. ► Current infrastructure and market organisation could handle 25% wind power. ► Demand response to hourly electricity prices leads to limited welfare gain. ► Consecutive hours with high or low price, or high or low wind are relatively few.

    This study provides an examination of various market and policy barriers to demand response providing ancillary services in both ISO/RTO and non-ISO/RTO regions, especially at the program provider level. It is useful to classify barriers in order to create a holistic understanding and identify parties that could be responsible for their removal. This study develops a typology of barriers focusing on smaller customers that must rely on a program provider (i.e., electric investor owned utility or IOU, ARC) to create an aggregated DR resource in order to bring ancillary services to the balancing authority. The barriers were identified through examinations of regulatory structures, market environments, and product offerings; and discussions with industry stakeholders and regulators. In order to help illustrate the differences in barriers among various wholesale market designs and their constituent retail environments, four regions were chosen to use as case studies: Colorado, Texas, Wisconsin, and New Jersey.

    Full Text Available The strategy of most households is to eliminate the negative effects of economic changes related mainly to the economic crisis by mobilizing available resources and reducing costs, but which cloud lead to a decrease in food consumption and changes in consumption patterns. Pensions and prices are factors that shape the demand for food and other estates. Both of these factors guarantee the economic viability of nutrition. Paper analyzes the development of the of milk consumption and level of its substitution by milk products. There was quantified the elasticity of demand and  estimated own price elasticity and income elasticity. For the past 17 years, consumption of milk, except cheese, cottage cheese, sour milk products and butter, decreased. Expressed by linear regression model in recent years (since 1995 in Slovakia occurred overall reduction in the consumption of milk and dairy products by an average of 0.988 kg per capita per year. This development was mainly conditioned by the annual descent of demand for milk, as its consumption with little variation in average decreased annually by up to 1.88 kg per capita. This development is largely due to the increase of milk prices and especially the increasing supply of a wide range of quality and flavored sour milk and cheese products. Acidified milk product consumption in recent observed years increased and is expressed by the average growth factor of 0.6748 kg per capita per year. Prognosis with a five percent risk of error of estimate could increase their consumption up to 13.936 kg per capita in 2014. Consumption of cheese and curd should the increase the current trend by an average of 0.0476 kg per person and would be able to achieve the level of consumption of 11.03 kg per capita in 2014.doi:10.5219/236

    The market for ethanol has grown from approximately 1.2 billion gallons in 1997 to almost 5 billion gallons in 2006. With the huge increase in ethanol demand in recent years, the growth in derived demand for corn has driven up many food prices. This paper uses monthly data from 1997-2006 to estimate the market supply and demand for ethanol at the national level. The simultaneous determination of the supply and demand curves using two-stage least squares allows for the calculation of supply and demand-side elasticities, which are important results in light of the tremendous growth in this market and recent legislation concerning ethanol.

    Larson, L.H.

    1991-01-01

    This paper reports that Canadian natural gas exports to the United States commenced in 1957 and have now reached 1.3 Tcf per year. Natural gas consumption in the united States is currently 25% of the total energy consumption, which is expected t grow considerably by the year 2000. National security and environmental concerns will make natural gas an increasingly desirable fuel, and U.S. domestic gas reserves will be insufficient to supply the demand growth. Consequently, there is a growing opportunity for increased sales of Canadian natural gas to the united States provided economic, regulatory and political situations do not deprive U.S. consumers of the opportunity to utilize this source of the world's cleanest fuel

  16. An assessment of market and policy barriers for demand response providing ancillary services in U.S. electricity markets

    International Nuclear Information System (INIS)

    Cappers, Peter; MacDonald, Jason; Goldman, Charles; Ma, Ookie

    2013-01-01

    An impact of increased variable renewable generation is the need for balancing authorities to procure more ancillary services. While demand response resources are technically capable of providing these services, current experience across the U.S. illustrates they are relatively minor players in most regions. Accessing demand response resources for ancillary services may require a number of changes to policies and common practices at multiple levels. Regional reliability councils must first define ancillary services such that demand response resources may provide them. Once the opportunity exists, balancing authorities define and promulgate rules that set the infrastructure investments and performance attributes of a resource wishing to provide such services. These rules also dictate expected revenue streams which reveal the cost effectiveness of these resources. The regulatory compact between utility and state regulators, along with other statutes and decisions by state policymakers, may impact the interest of demand response program providers to pursue these resources as ancillary service providers. This paper identifies within these broad categories specific market and policy barriers to demand response providing ancillary services in different wholesale and retail environments, with emphasis on smaller customers who must be aggregated through a program provider to meet minimum size requirements for wholesale transactions. - Highlights: • We identify barriers keeping demand response from providing ancillary services. • Institutional, financial and program provider business model barriers exist. • Product definitions and rules do not always accommodate demand response well. • Expected revenues are uncertain and may not exceed required investments costs. • Regulatory compact and state statutes limit opportunities for program providers

    It clearly shows that the whole energy sector is on the move, pulled this way and that by the conflicting demands of competition and politics. The utilities face enormous pressure on costs, while customers enjoy an unprecedented measure of freedom. No one can avoid the pressure of the market, not even politicians. The latter should recognize that there is no point in hobbling an industry that has to face up to the European competition, and that fair conditions of competition are essential. If the political conditions are right, the current tensions may ultimately turn out to be fruitful and release new energies from which all will profit. (orig.) [de

    Energy Technology Data Exchange (ETDEWEB)

    1997-09-01

    Retail electricity competition will allow customers to select their own power suppliers and some customers will make purchase decisions based, in part, on their concern for the environment. Green power marketing targets these customers under the assumption that they will pay a premium for ``green`` energy products such as renewable power generation. But renewable energy is not a traditional product because it supplies public goods; for example, a customer supporting renewable energy is unable to capture the environmental benefits that their investment provides to non-participating customers. As with all public goods, there is a risk that few customers will purchase ``green`` power and that many will instead ``free ride`` on others` participation. By free riding, an individual is able to enjoy the benefits of the public good while avoiding payment. This report reviews current green power marketing activities in the electric industry, introduces the extensive academic literature on public goods, free riders, and collective action problems, and explores in detail the implications of this literature for the green marketing of renewable energy. Specifically, the authors highlight the implications of the public goods literature for green power product design and marketing communications strategies. They emphasize four mechanisms that marketers can use to increase customer demand for renewable energy. Though the public goods literature can also contribute insights into the potential rationale for renewable energy policies, they leave most of these implications for future work (see Appendix A for a possible research agenda).

    Full Text Available Economic efficiency is a key issue in economic research and for policy design, and certainly for food security challenges. In the food system dynamics the understanding of changes and trends is crucial to improve our capacity to deal with the objectives of sustainable development and quality of life. Food system efficiency evaluation is necessary with regard to production and consumption efficiencies as well as market and governance dilemmas. Regulations and institutional efficiency are crucial aspects that are frequently forgotten, and efforts should be made to improve the capacity to deal with those methodological needs. In many situations, in the real world, data and measurements are difficult or even impossible to get in numeric or quantitative terms. Frequently, a qualitative evaluation is the only way to proceed, but measurements and numeric references are still important, mainly when changes over time are central to the research. The actual paper follows a structural food system model (WFSE – World Food Security Equation and a general equilibrium approach (ICI model – induced changes and innovation model to show in a country case study (Cape Verde the important role of markets and institutions as compared to regulation practices directed to improve economic efficiency subject to demand behavior.

    Increased energy efficiency is one of the pillars for reducing CO 2 emissions. However, in models for the electricity market like unit commitment and dispatch models, increased efficiency of demand results in a paradoxical apparent reduction of the total economic surplus. The reason is that these are partial models for the electricity market, which do not take into account the effect of the changes in other markets. This paper shows how the calculation of the consumer surplus in the electricity market should be corrected to take into account the effect in other markets. In different cases we study shifts in the demand curve that are caused by increased energy efficiency, reduced cost for substitutes to electricity and real-time monitoring of demand, and we derive the necessary correction. The correction can easily be included in existing simulation models, and makes it possible to assess the effect of changes in demand on economic surplus. (author)

Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

  17. Demand Side Management in a competitive European market: Who should be responsible for its implementation?

    International Nuclear Information System (INIS)

    Didden, Marcel H.; D'Haeseleer, William D.

    2003-01-01

    Demand side management (DSM), more specifically energy efficiency, is standing in the spotlight due to the Kyoto commitments. An additional factor, the liberalization of the electricity markets, causes every country to review its own DSM activities. Especially in Europe, where the directive for opening the electricity market has a direct impact on the current DSM frameworks, governments will have to consider a change in this framework. In order to achieve this, much research has been done in the past years on how to change the DSM framework in a way that the requirements of both liberalization and the Kyoto Protocol will be met. In this paper, we review the current DSM activities and ongoing research from the starting point 'who should be responsible for implementing DSM'. We conclude that countries have to make explicit choices on how to arrange their DSM activities for the different customers groups. They have to be aware of the fact that some combinations of DSM activities will lead to counter-productive results and therefore inefficiency. This paper also investigates which of these DSM activities fits best in the open market; a critical review of Integrated Resource Planning (IRP) is used as a starting point. We agree with various proponents of IRP that planning towards minimal societal costs is theoretically appropriate, looking from a societal point of view. We also indicate in this paper that the planning process IRP is partly applicable in the open market. But looking at the practical application of IRP in the past, we must conclude that there are better alternatives for achieving energy efficient goals in a liberalized market

    One third of primary energy consumption is today being used to generate electrical power. The author discusses with the aid of statistics and diagrams, the various uses of energy, and the per capita energy consumption throughout the world. He considers that future demand for power depends to a large extent on GNP but also on fuel prices and reserves, energy policies and environmental concerns. On balance, these will lead to the introduction of clean coal technologies and a renaissance of nuclear power stations in the near future but until then gas-fired power plant will continue to play a dominant role in meeting power demands. 9 figs., 8 tabs.

    Full Text Available In recent years, more and more companies start online operation. Electronic market becomes a key component of some companies’ strategy. Supply chain management is another key component of the strategy as being adopted by an increasing number of companies. There are many interactions between electronic market and supply chain. One of the key questions is to select one type of electronic market from the view of supply chain. This paper develops some models to explore the issue of selection between public electronic market and private electronic market in three scenarios where electronic market is used for buying, for selling, and for both selling and buying, respectively. In a public electronic market, neither the supplier nor the retailer is the owner of the electronic market. However, in a private electronic market, there is an owner that is either the supplier or the retailer. Besides demand uncertainty, we take into account the price uncertainty in electronic market. We explore the conditions under which the agent of supply chain selects one certain type of electronic market by comparing expected profits of supply chain members in different scenarios. Some sensitivity analyses are conducted to explore the impact of the customer demand, electronic market retail price, and e-market use fee on the selection of electronic market. Finally, some interesting managerial and academic insights are obtained.

    Highlights: • Studying heating market impact on energy hub operation considering price uncertainty. • Investigating impact of implementation of heat demand response on hub operation. • Presenting stochastic method to consider wind generation and prices uncertainties. - Abstract: Multi carrier energy systems or energy hubs has provided more flexibility for energy management systems. On the other hand, due to mutual impact of different energy carriers in energy hubs, energy management studies become more challengeable. The initial patterns of energy demands from grids point of view can be modified by optimal scheduling of energy hubs. In this work, optimal operation of multi carrier energy system has been studied in the presence of wind farm, electrical and thermal storage systems, electrical and thermal demand response programs, electricity market and thermal energy market. Stochastic programming is implemented for modeling the system uncertainties such as demands, market prices and wind speed. It is shown that adding new source of heat energy for providing demand of consumers with market mechanism changes the optimal operation point of multi carrier energy system. Presented mixed integer linear formulation for the problem has been solved by executing CPLEX solver of GAMS optimization software. Simulation results shows that hub’s operation cost reduces up to 4.8% by enabling the option of using thermal energy market for meeting heat demand.

  6. Entanglement Between Demand and Supply in Markets with Bandwagon Goods

    Gordon, Mirta B.; Nadal, Jean-Pierre; Phan, Denis; Semeshenko, Viktoriya

    2013-05-01

    Whenever customers' choices (e.g. to buy or not a given good) depend on others choices (cases coined `positive externalities' or `bandwagon effect' in the economic literature), the demand may be multiply valued: for a same posted price, there is either a small number of buyers, or a large one—in which case one says that the customers coordinate. This leads to a dilemma for the seller: should he sell at a high price, targeting a small number of buyers, or at low price targeting a large number of buyers? In this paper we show that the interaction between demand and supply is even more complex than expected, leading to what we call the curse of coordination: the pricing strategy for the seller which aimed at maximizing his profit corresponds to posting a price which, not only assumes that the customers will coordinate, but also lies very near the critical price value at which such high demand no more exists. This is obtained by the detailed mathematical analysis of a particular model formally related to the Random Field Ising Model and to a model introduced in social sciences by T.C. Schelling in the 70's.

  7. Fuel switching? Demand destruction? Gas market responses to price spikes

    International Nuclear Information System (INIS)

    Lippe, D.

    2004-01-01

    This presentation defined fuel switching and addressed the issue regarding which consumers have the capability to switch fuels. In response to short term price aberrations, consumers with fuel switching capabilities reduce their use of one fuel and increase consumption of an alternative fuel. For example, natural gas consumption by some consumers declines in response to price spikes relative to prices of alternative fuels. This presentation also addressed the issue of differentiating between fuel switching and demand destruction. It also demonstrated how to compare gas prices versus alternative fuel prices and how to determine when consumers will likely switch fuels. Price spikes have implications for long term trends in natural gas demand, supply/demand balances and prices. The power generating sector represents a particular class of gas consumers that reduce operating rates of gas fired plants and increase operating rates of other plants. Some gas consumers even shut down plants until gas prices declines and relative economies improve. Some practical considerations for fuel switching include storage tank capacity, domestic refinery production, winter heating season, and decline in working gas storage. tabs., figs

    Full Text Available In this paper capacity withholding in an oligopolistic electricity market that all Generation Companies (GenCos bid in a Cournot model is analyzed and the capacity withheld index, the capacity distortion index and the price distortion index are obtained and formulated. Then a new index, Distortion-Withheld Index (DWI, is proposed in order to measure the potential ability of market for capacity withholding. In these indices the impact of demand elasticity on capacity withholding is considered and it is shown that demand elasticity plays an important role for capacity withholding and market power mitigation. Due to the significant role of forward contracts for market power mitigation and risk hedging in power markets, the impacts of these contracts on capacity withholding are considered. The effects of GenCos’ strategic forward contracts on capacity withholding are also discussed. Moreover, the relationship between capacity withholding of GenCos and market price distortion is acquired. A two-settlement market including a forward market and a spot market is used to describe GenCos’ strategic forward contracting and spot market competition.

    Banda, E.C.; Tuan, L.A.

    2007-01-01

    A design mechanism for the optimal participation of customer load in electricity markets was presented. In particular, this paper presented a modified market model for the optimal procurement of interruptible loads participating in day-ahead electricity markets. The proposed model considers the effect of price elasticity and demand-response functions. The objective was to determine the role that price elasticity plays in electricity markets. The simulation model can help the Independent System Operator (ISO) identify customers offering the lowest price of interruptible loads and load flow patterns that avoid problems associated with transmission congestion and transmission losses. Various issues associated with procurement of demand-response offerings such as advance notification, locational aspect of load, and power factor of the loads, were considered. It was shown that demand response can mitigate price volatility by allowing the ISO to maintain operating reserves during peak load periods. It was noted that the potential benefits of the demand response program would be reduced when price elasticity of demand is taken into account. This would most likely occur in actual developed open electricity markets, such as Nordpool. This study was based on the CIGRE 32-bus system, which represents the Swedish high voltage power system. It was modified for this study to include a broad range of customer characteristics. 18 refs., 2 tabs., 14 figs

Increasing renewable energy penetration depends on both technical and economic factors. Distribution system consumers can contribute to grid stability by controlling residential electrical device power consumed by water heaters and battery storage systems. Coupled with dynamic supply pricing strategies, a comprehensive system for demand response (DR) exist. Proper DR management will allow greater integration of renewable energy sources partially replacing energy demand currently met by the combustion of fossil-fuels. An enticing economic framework providing increased value to consumers compensates them for reduced control of devices placed under a DR aggregator. Much work has already been done to develop more effective ways to implement DR control systems. Utilizing an integrated approach that combines consumer requirements into aggregate pools, and provides a dynamic response to market and grid conditions, we have developed a mathematical model that can quantify control parameters for optimum demand response and decide which resources to switch and when. In this model, optimization is achieved as a function of cost savings vs. customer comfort using mathematical market analysis. Two market modeling approaches—the Cournot and SFE—are presented and compared. A quadratic function is used for presenting the cost function of each DRA (Demand

    2016-01-01

    Demand Response allows for the management of demand side resources in real-time; i.e. shifting electricity demand according to fluctuating supply. When integrated into electricity markets, Demand Response can be used for load shifting and as a replacement for both control reserve and balancing energy. These three usage scenarios are compared based on historic German data from 2011 to determine that load shifting provides the highest benefit: its annual financial savings accumulate to €3.110 M for both households and the service sector. This equals to relative savings of 2.83% compared to a scenario without load shifting. To improve Demand Response integration, the proposed model suggests policy implications: reducing bid sizes, delivery periods and the time-lag between market transactions and delivery dates in electricity markets. - Highlights: •Comparison of 3 scenarios to integrate Demand Response into electricity markets. •These are: optimize procurement, offer as control reserve, avoid balancing energy. •Ex post simulation to quantify financial impact and policy implications. •Highest savings from load shifting with a cost reduction of 3%. •Model suggests reducing bid sizes, delivery periods and time lags as policy issues.

    2014-09-01

    To understand the trends in any physician services market it is necessary to understand the nature of both supply and demand, but few studies have jointly examined supply and demand in these markets. This study uses aggregate panel data on general practitioner (GP) services at the Statistical Local Area level in Australia spanning eight years to estimate supply and demand equations for GP services. The structural equations of the model are estimated separately using population-weighted fixed effects panel modelling with the two stage least squares formulation of the generalised method of moments approach (GMM (2SLS)). The estimated price elasticity of demand of [Formula: see text] is comparable with other studies. The direct impact of GP density on demand, while significant, proves almost immaterial in the context of near vertical supply curves. Supply changes are therefore due to shifts in the position of the curves, partly determined by a time trend. The model is validated by comparing post-panel model predictions with actual market outcomes over a period of three years and is found to provide surprisingly accurate projections over a period of significant policy change. The study confirms the need to jointly consider supply and demand in exploring the behaviour of physician services markets.

    Full Text Available The current situation calls for research to be directed towards strategic objectives for recovery aimed at the transferability of results. For technological research in architecture, this involves analysing critical situations in the processes of transforming the built environment and, in the first place, in the construction of public works. The article identifies them as the conflict between the main decision-making areas and the inefficiency of the procedural mechanisms introduced to overcome them. The assumption is the recovery of an ethical dimension, but research has a duty to promote a technical and managerial culture, which is currently lacking, and to develop tools that facilitate informed consultation among the players. Even at international level, priority should be given to acting on organizational process models that highlight transdisciplinary collaboration principles in real time and throughout the entire development of an intervention programme.

    2006-01-01

    This paper reviews the development of renewable energy in Germany from 1973 to 2003. It investigates the relative importance of energy policy and green power marketing in shaping the renewable energy market. More than a decade of consistent policy support for renewables under the feed-in law (StrEG) and its successor (EEG) has been an important driver for increasing renewable electricity generation to date, putting the country in a better position than most of its peers when it comes to achieving European Union targets for renewable energy. Green power marketing driven by customer demand, on the other hand, is growing, but has had limited measurable impact so far. We discuss potential intangible benefits of green power marketing and scenarios for future market development. The paper concludes with lessons that can be learned from the German case for policy design and market development in other countries

    2014-05-01

    This paper deals with the practical problems related to long-term issues in electricity markets in the presence of demand response development. Different policies have been implemented around the world aiming to develop demand response potential. Externalities, in particular the CO_2 externality, have been one of the key elements in the debate on the effectiveness of different policies regarding demand response development. Policy makers have several options to deal with this externality. The most direct one is to correct the externality by setting a CO_2 price at a level that corresponds to the cost to society of the corresponding CO_2 emissions. One alternative solution could be to subsidize carbon-free technologies as demand response. In this paper we examine potential long-term impacts of these two policies. We rely on a long-term market simulation model that characterizes expansion decisions in a competitive regime. We test for each policy two different scenarios regarding the possibility of internalization of the CO_2 externality. The results show that differences in development policies affect both investments and social costs in the wholesale electricity market and confirm previous findings that a market-driven development of demand response with the internalization of the CO_2 externality is the most efficient approach.

  10. The effects of demand uncertainty on strategic gaming in the merit-order electricity pool market

    Science.gov (United States)

    Frem, Bassam

    In a merit-order electricity pool market, generating companies (Gencos) game with their offered incremental cost to meet the electricity demand and earn bigger market shares and higher profits. However when the demand is treated as a random variable instead of as a known constant, these Genco gaming strategies become more complex. After a brief introduction of electricity markets and gaming, the effects of demand uncertainty on strategic gaming are studied in two parts: (1) Demand modelled as a discrete random variable (2) Demand modelled as a continuous random variable. In the first part, we proposed an algorithm, the discrete stochastic strategy (DSS) algorithm that generates a strategic set of offers from the perspective of the Gencos' profits. The DSS offers were tested and compared to the deterministic Nash equilibrium (NE) offers based on the predicted demand. This comparison, based on the expected Genco profits, showed the DSS to be a better strategy in a probabilistic sense than the deterministic NE. In the second part, we presented three gaming strategies: (1) Deterministic NE (2) No-Risk (3) Risk-Taking. The strategies were then tested and their profit performances were compared using two assessment tools: (a) Expected value and standard deviation (b) Inverse cumulative distribution. We concluded that despite yielding higher profit performance under the right conjectures, Risk-Taking strategies are very sensitive to incorrect conjectures on the competitors' gaming decisions. As such, despite its lower profit performance, the No-Risk strategy was deemed preferable.

  11. Coal transport demand in Western Europe and Japan: Impacts of energy market liberalisation and climate policy

    International Nuclear Information System (INIS)

    Golombek, Rolf; Kittelsen, Sverre A.C.; Maestad, Ottar

    2005-12-01

    Western Europe and Japan are among the main importers of coal. Climate policies following the Kyoto agreement are creating pressure to substitute away from coal and turn to less emission intensive energy sources. At the same time, liberalizations of energy markets in Europe and Japan are likely to cause reduced electricity prices, which will boost the overall demand for electricity. This paper analyses the combined effect of electricity market liberalization and climate policies on the international coal trade. Using the numerical equilibrium model LIBEMOD, we find that while liberalization of electricity markets will imply a large increase in aggregate coal transport demand, the negative impact of climate policies may be even larger, in particular if Russia and Ukraine utilise their market power in the market for emission permits. If this market power is exploited, the total effect of liberalisation and climate policy - when including the impact of general economic growth - is a 20% reduction in aggregate coal transport between 2000 and 2010. Further, impacts differ markedly between Western Europe and Japan. A main difference is that liberalisation has a much more positive - and climate policies have a much stronger negative - impact on steam coal demand in Western Europe than in Japan

  12. Current rules and state of readiness of the competitive market

    Campbell, B.

    2001-01-01

    The focus of this presentation was on the governance, operation and regulation of the Independent Market Operator (IMO) in a competitive electricity market in Ontario. The presentation also included an update on the progress toward market readiness and discussed the principles guiding government decision making, recognizing that it is government that holds the decision on the market opening date. The IMO has been running Ontario's bulk electric system for more than 50 years, overseeing its safe and reliable operation while balancing demand and supply. IMOs are also leading the drive to a competitive, deregulated wholesale electricity marketplace in Ontario. When open, IMOs will run the electricity spot market, collecting offers from suppliers and bids from purchasers to determine a spot market price for electricity which will reflect demand across the province. Rules and processes are being developed to ensure the Ontario marketplace will operate to benefit both consumers and producers. The four principles guiding governments in the opening of electricity markets are to protect consumers and offer more choice, ensure a strong business climate with a reliable supply of electricity, to protect the environment, and to support alternative sources of power

  14. What is demand response? Contributing to secure security-of-supply at the electricity markets

    International Nuclear Information System (INIS)

    Grenaa Jensen, Stine; Skytte, Klaus; Togeby, Mikael

    2004-01-01

    There is a common understanding that demand response can reduce the total costs of electricity reliability. There has especially been a growing interest in the electricity market where high spot prices in peak periods and blackouts have recently been seen. It is not easy from the existing literature to find a common definition of demands response. Often the term demand response is used broadly without looking at the time dimension. However, it does not make sense to talk about demand response without talking about when, for how long the energy is used or saved, and at which costs. This paper surveys these subjects and set up a systematic grouping of the different characteristics of demand response. It especially looks at the time dimension. (au)

    2008-06-01

    Full Text Available Since 1966, approximately 1 000 veterinarians graduate each year from 16 veterinary schools in Japan. According to reports submitted by veterinarians to the Ministry of Agriculture, Forestry and Fisheries in January 2007, there were over 35 818 veterinarians in Japan at the end of 2006. Of this total, 13 202 (36.8% were engaged in companion animal practice, 9 112 (25.4% were civil servants and 4 180 (11.7% were engaged in food animal practice. The total number of veterinarians has increased gradually over the past 40 years. Recently, the number of veterinarians engaged in companion animal practice has increased while the number of veterinarians engaged in food animal practice is declining. These trends reflect the change in demand for veterinarians in food and companion animal practice, resulting mainly from changes in the number of food animals and companion animals in recent years. The number of veterinarians in the public sector has decreased gradually due to the administrative reforms of recent years.

    Full Text Available In competitive and constantly changing market conditions special attention has been paid to market researches. The results of these studies become the basis for formation of sales estimates, and projected levels of revenues and profits from sales. Market researches are the essential condition to make offered goods successful at the market. It is market researches that help companies to realize the control of consumers' needs changing. The market researches on demand for dietary and prophylactic nutrition in the Saratov Region have been the research objective. In accordance with the given objective the following goals have been formed: 1 finding out the most spread diseases among the population; 2 determination of the average age of people suffering from one or another disease; 3 studying demand of products with food fiber additives; 4 analysis of respondent's preference regarding the addition of natural vegetable additives to foodstuff; 5 demand for dietary and prophylactic foodstuff among the population. Since the survey has been carried out among people suffering from various diseases, particular attention during the market research has been turned to the medical and prophylactic properties of food fibers to find out the attitude of the respondents to functional foodstuff. The dynamics of noninfectious diseases, the population health status depending on age, and increase of overweight people during 2012–2014 have been shown. As a result of questionnaire data processing it has been ascertained that the population is of low awareness regarding the necessity to consume foodstuff with radioprotective and chelator properties. The researches have demonstrated that dietary and prophylactic foodstuff is in demand and consequently the development of such products is reasonable.

  17. Important Factors for Early Market Microgrids: Demand Response and Plug-in Electric Vehicle Charging

    Science.gov (United States)

    White, David Masaki

    Microgrids are evolving concepts that are growing in interest due to their potential reliability, economic and environmental benefits. As with any new concept, there are many unresolved issues with regards to planning and operation. In particular, demand response (DR) and plug-in electric vehicle (PEV) charging are viewed as two key components of the future grid and both will likely be active technologies in the microgrid market. However, a better understanding of the economics associated with DR, the impact DR can have on the sizing of distributed energy resource (DER) systems and how to accommodate and price PEV charging is necessary to advance microgrid technologies. This work characterizes building based DR for a model microgrid, calculates the DER systems for a model microgrid under DR through a minimization of total cost, and determines pricing methods for a PEV charging station integrated with an individual building on the model microgrid. It is shown that DR systems which consist only of HVAC fan reductions provide potential economic benefits to the microgrid through participation in utility DR programs. Additionally, peak shaving DR reduces the size of power generators, however increasing DR capacity does not necessarily lead to further reductions in size. As it currently stands for a microgrid that is an early adopter of PEV charging, current installation costs of PEV charging equipment lead to a system that is not competitive with established commercial charging networks or to gasoline prices for plug-in hybrid electric vehicles (PHEV).

    Rassenti, Stephen J; Smith, Vernon L; Wilson, Bart J

    2003-03-04

    In this article we report an experiment that examines how demand-side bidding can discipline generators in a market for electric power. First we develop a treatment without demand-side bidding; two large firms are allocated baseload and intermediate cost generators such that either firm might unilaterally withhold the capacity of its intermediate cost generators from the market to benefit from the supracompetitive prices that would result from only selling its baseload units. In a converse treatment, ownership of some of the intermediate cost generators is transferred from each of these firms to two other firms such that no one firm could unilaterally restrict output to spawn supracompetitive prices. Having established a well controlled data set with price spikes paralleling those observed in the naturally occurring economy, we also extend the design to include demand-side bidding. We find that demand-side bidding completely neutralizes the exercise of market power and eliminates price spikes even in the presence of structural market power.

    Full Text Available The Chinese retail industry is expected to grow dramatically over the next few years, owing to the rapid increase in purchasing power of Chinese consumers. Retail managers should analyze the market demands and avoid dull sales to promote the sustainable development of the retail industry. Economic sustainability in the retail industry, which refers to a suitable return of investment, requires the implementation of precise product allocation strategies in different regions. This study proposed a hybrid model to evaluate economic sustainability in the preparation of goods of retail shops on the basis of market demand evaluation. Through a grid-based convolutional neural network, a regression model was first established to model the relationship between consumer distribution and the potential market demand. Then, another model was proposed to evaluate the sustainability among regions based on their supply-demand analysis. An experiment was conducted based on the actual sales data of retail shops in Guiyang, China. Results showed an immense diversity of sustainability in the entire city and three classes of regions were distinguished, namely, high, moderate, and limited. Our model was proven to be effective in the sustainability evaluation of supply and demand in the retail industry after validation showed that its accuracy reached 92.8%.

    Based on the status that the green market began to develop (e.g. pharmaceutical industry) in Mainland China, the paper mainly discusses how members of the green supply chain (GSC) cooperate effectively in the process of the supply chain operations. For the uncertainties existing in the market demand of the green products, the GSC coordination strategy is put forward based on the Stackelberg game that the manufacturer is the leader and distributors are the followers. The relationship between the proposed coordination strategy and several factors including the distributor's amount, the distributor's risk aversion and the uncertainties of market demand are analyzed. It indicates that, when there are uncertainties existing in the market demand of the green product, the revenue of each enterprise, the overall revenue and the customer's welfare all decrease; while the increase in the number of distributors and low risk aversion of them are beneficial to the entire GSC and the customer. The conclusions have good guidance for the operational decisions of the green supply chain when the green market is in its initial formation.

    Full Text Available The article is aimed at analyzing the market for dental services in Ukraine in the implantology segment, studying the demand factors for these services and developing a system of measures to manage the demand for dental implantation services. It has been proven that the market for dental services according to a complex of its attributes is more in line with the type of market of monopolistic competition. One of the promising ways of developing the dental market is to transform producers of dental services into the vertically integrated holdings. As one of the specific features of the dental services market is allocated the asymmetry of information, which leads to a conflict between the medical and economic interests of dentists. The price and non-price factors of demand for dental implantation services were determined, the prime cost structure of a dental service was analyzed. The characteristic attributes of a medical service have been defined as consistently defined actions or a complex of actions by medical personnel aimed at prevention, diagnosis, treatment, and rehabilitation, which have a self-contained complete meaning and a certain price.

    2016-01-01

    Electricity sector has been transformed from state-owned monopolistic utilities to competitive markets with an aim to promote incentives for improving efficiency, reducing costs and increasing service quality to customers. One of the cardinal assumptions of the liberalized and competitive electricity markets is the rational actor, and decision-makers are assumed to make the best decisions that maximize their utility. However, a vast literature on behavioral economics has shown the weakness of economic theory in explaining and predicting individuals’ decision-making behavior. This issue is quite important for competition in electricity markets in which consumers’ preferences have a significant role. Despite its importance, this issue has almost been neglected in Turkey, which has taken major steps in electricity sector restructuring. Therefore, this paper aims to examine switching and demand response behavior in Turkish electricity market by using multiple correspondence and panel data analysis, and findings are discussed in light of the neoclassical and behavioral economics literature. Analyses’ results show that consumers’ switching and demand response behavior is consistent with the neoclassical literature to some extent; however, behavioral factors are also affecting consumers’ decisions. Furthermore, there are systemic problems that hinder effective functioning of the electricity market and restrict competition. - Highlights: • Behavioral economics can provide insights for consumer’ decisions. • Switching and demand response behavior is examined by econometric methods. • Results is consistent with the neoclassical literature to some extent • However, behavioral factors are also affecting consumers’ decisions.

    Full Text Available The state of health of the population is one of the most important indicators of the well-being of the nation. Important directions of health care reform are optimization of management, rational distribution of limited financial resources, efficient use of material resources, introduction of health insurance, restructuring of treatment and preventive care to the people. Marketing of medical services market is one of the most complex types of marketing. Because it is medical services that are connected with the protection and maintenance of the most important values ​​of a person - life and health. The market for medical services is a combination of socio-economic relations in the healthcare sector. The most important components of the analysis of any market, including the market of medical services, are marketing research, which is a systematic collection, processing, analysis of data and information in order to formulate proposals for effective activities on it. In the field of public health, marketing can be defined as a complex process of planning, economic substantiation and management of the process of provision of medical services, the formation of a pricing policy of the medical-preventive process, ensuring effective communication with patients. The purpose of the study is to identify the health of the population and determine the demand factors for paid health services and their demand. The main task set before market research on the health of the population is the formation and provision of benefits to consumers that meet their needs for qualified medical care and quality of life. The research methods used in the work are based on probabilistic, stratified, quota, representative samples for the entire population of Ivano-Frankivsk and Ivano-Frankivsk region.

    2017-05-01

    In this paper, we assess the U.S. demand for low-temperature thermal energy at the county resolution for four major end-use sectors: residential buildings, commercial buildings, manufacturing facilities, and agricultural facilities. Existing, publicly available data on the U.S. thermal demand market are characterized by coarse spatial resolution, with assessments typically at the state-level or larger. For many uses, these data are sufficient; however, our research was motivated by an interest in assessing the potential demand for direct use (DU) of low-temperature (30 degrees to 150 degrees C) geothermal heat. The availability and quality of geothermal resources for DU applications are highly spatially heterogeneous; therefore, to assess the potential market for these resources, it is necessary to understand the spatial variation in demand for low-temperature resources at a local resolution. This paper presents the datasets and methods we used to develop county-level estimates of the thermal demand for the residential, commercial, manufacturing, and agricultural sectors. Although this analysis was motivated by an interest in geothermal energy deployment, the results are likely to have broader applications throughout the energy industry. The county-resolution thermal demand data developed in this study for four major U.S. sectors may have far-reaching implications for building technologies, industrial processes, and various distributed renewable energy thermal resources (e.g. biomass, solar).

    2006-01-01

    Although electricity is theoretically an inelastic good in the short term, the steep slope of the supply stack implies that even modest response by demand could translate into reduced capacity requirements and significant price decreases. This article examined the effect of price-responsive demand strategies in an actual deregulated electricity industry. Auction data from the New York Independent System Operator (NYISO) day-ahead electricity market were used to form supply stacks for various zones. A simple linear demand function was used to determine the effect of price responsiveness on equilibrium spot market price and consumption. The aim was to quantify the benefits from the pricing protocol and to determine whether modest levels of price elasticity can significantly lower prices and consumption. Market-clearing prices and quantities were estimated using various supply curves in order to quantify the responsiveness necessary to achieve given price reductions. Price response was induced in the demand curve by varying its slope. Estimates were then used to estimate the average level of slope needed to reduce the average market-clearing price during the year by a certain percentage. Results showed that an average slope of -50.04 was necessary for prices to be reduced by 25 per cent. Results also showed that necessary price responses can be ascertained for any desired reduction in the market-clearing price or quantity. Although price responsiveness unambiguously reduces the spot market price and quantity, its effect on the forward price is not yet clear. It was concluded that a separate analysis of peak hours may reveal the effectiveness of enhanced price response. 8 refs., 1 tab., 8 figs

    Urban population growth, climate and land use change are expected to boost residential water demand in urban contexts in the next decades. In such a context, developing suitable demand-side management strategies is essential to meet future water demands, pursue water savings, and reduce the costs for water utilities. Yet, the effectiveness of water demand management strategies (WDMS) relies on our understanding of water consumers' behavior, their consumption habits, and the water use drivers. While low spatial and temporal resolution water consumption data, as traditionally gathered for billing purposes, hardly support this understanding, the advent of high-resolution, smart metering technologies allowed for quasi real-time monitoring water consumption at the single household level. This, in turn, is advancing our ability in characterizing consumers' behavior, modeling, and designing user-oriented residential water demand management strategies. Several water smart metering programs have been rolled-out in the last two decades worldwide, addressing one or more of the following water demand management phases: (i) data gathering, (ii) water end-uses characterization, (iii) user modeling, (iv) design and implementation of personalized WDMS. Moreover, the number of research studies in this domain is quickly increasing and big economic investments are currently being devoted worldwide to smart metering programs. With this work, we contribute the first comprehensive review of more than 100 experiences in the field of residential water demand modeling and management, and we propose a general framework for their classification. We revise consolidated practices, identify emerging trends and highlight the challenges and opportunities for future developments given by the use of smart meters advancing residential water demand management. Our analysis of the status quo of smart urban water demand management research and market constitutes a structured collection of information

  15. Market Power with Interdependent Demand. Sale of Emission Permits and Natural Gas from Russia

    With implementation of the Kyoto Protocol, Russia will most likely be able to exert market power in the emission permit market. But, as Russia is also a big exporter of fossil fuels, the incentives to boost the permit price may be weak. However, a significant share of Russia's fossil fuel exports is natural gas. If a high permit price boosts the demand for natural gas through substitution from more polluting fuels and thus increase gas profits, this may increase the incentives to exert monopoly power in the permit market. Moreover, a large fossil fuel exporter may use its market position to influence the effective demand for permits. Hence, the relationship between permit income and fossil fuels exports runs in both directions. In this article, we explore the interdependence between the revenues from permit and fossil fuel exports both theoretically and numerically. A computable general equilibrium model suggests the fact that Russia as a big gas exporter has small effect on the incentives to exert monopoly power in the permit market. Moreover, Russia's monopoly power in the permit market has a small, but non-negligible impact on the optimal level of Russian gas exports. (author)

    This paper presents a new multi-objective day-ahead market clearing (DAMC) mechanism with demand-side reserves/demand response (DR) offers, considering realistic voltage-dependent load modeling. The paper proposes objectives such as social welfare maximization (SWM) including demand-side reserves, and load served error (LSE) minimization. In this paper, energy and demand-side reserves are cleared simultaneously through co-optimization process. The paper clearly brings out the unsuitability of conventional SWM for DAMC in the presence of voltage-dependent loads, due to reduction of load served (LS). Under such circumstances multi-objective DAMC with DR offers is essential. Multi-objective Strength Pareto Evolutionary Algorithm 2+ (SPEA 2+) has been used to solve the optimization problem. The effectiveness of the proposed scheme is confirmed with results obtained from IEEE 30 bus system.

  17. The global nuclear fuel market - supply and demand 1995-2015

    The findings and main conclusions of the 1996 supply and demand report of the Uranium Institute are summarised. The previous report was published in June 1994. In 1994 and 1995, world uranium production remained at a relatively depressed level, accounting for just over half reactor requirements only. Since mid 1995, however, some increase in production has occurred alongside rises in uranium spot market prices. This may indicate that supply is becoming tighter and indicate the end of the perception that supply availability is unlimited. Answers are attempted to the questions about the future which arise from this development. Nuclear power is first set in the context of the market for energy and for electricity in particular. The report then identifies key issues for the longer term future for nuclear power and considers various aspects of nuclear fuel supply and demand over the next 20 years. Three demand scenarios are explored. Even in the lower requirements case, the overall conclusion is that supply will only meet demand from 2002 onwards when all the projected new mine capacity is in place. Adequate supply is heavily dependent on other supply sources in the higher case scenarios. The market will need the entry of blended down high enriched uranium from dismantled weapons and an increased contribution from the reprocessing of spent fuel. Additional primary production is only likely if financial incentives are available and the regulatory framework permits. Finally, there is the possibility of re-enriching depleted uranium.

    This paper presents a search algorithm based framework to calibrate origin-destination (O-D) market specific airline ticket demands and prices for the Air Transportation System (ATS). This framework is used for calibrating an agent based model of the air ticket buy-sell process - Airline Evolutionary Simulation (Airline EVOS) -that has fidelity of detail that accounts for airline and consumer behaviors and the interdependencies they share between themselves and the NAS. More specificially, this algorithm simultaneous calibrates demand and airfares for each O-D market, to within specified threshold of a pre-specified target value. The proposed algorithm is illustrated with market data targets provided by the Transportation System Analysis Model (TSAM) and Airline Origin and Destination Survey (DB1B). Although we specify these models and datasources for this calibration exercise, the methods described in this paper are applicable to calibrating any low-level model of the ATS to some other demand forecast model-based data. We argue that using a calibration algorithm such as the one we present here to synchronize ATS models with specialized forecast demand models, is a powerful tool for establishing credible baseline conditions in experiments analyzing the effects of proposed policy changes to the ATS.

    2011-09-10

    This scoping study focuses on the policy issues inherent in the claims made by some Smart Grid proponents that the demand response potential of mass market customers which is enabled by widespread implementation of Advanced Metering Infrastructure (AMI) through the Smart Grid could be the “silver bullet” for mitigating variable generation integration issues. In terms of approach, we will: identify key issues associated with integrating large amounts of variable generation into the bulk power system; identify demand response opportunities made more readily available to mass market customers through widespread deployment of AMI systems and how they can affect the bulk power system; assess the extent to which these mass market Demand Response (DR) opportunities can mitigate Variable Generation (VG) integration issues in the near-term and what electricity market structures and regulatory practices could be changed to further expand the ability for DR to mitigate VG integration issues over the long term; and provide a qualitative comparison of DR and other approaches to mitigate VG integration issues.

    The high penetration of both Distributed Energy Resources (DER) and Demand Response (DR) in modern power systems requires a sequence of advanced strategies and technologies for maintaining system reliability and flexibility. Real-time electricity markets (RTM) are the nondiscriminatory transaction...... platforms for providing necessary balancing services, where the market clearing (nodal or zonal prices depending on markets) is very close to real time operations of power systems. One of the primary functions of RTMs in modern power systems is establishing an efficient and effective mechanism for small DER...... and DR to participate in balancing market transactions, while handling their meteorological or intermittent characteristics, facilitating asset utilization, and stimulating their active responses. Consequently, RTMs are dedicated to maintaining the flexibility and reliability of power systems. This paper...

  3. A Methodology for Estimating Large-Customer Demand Response MarketPotential

    2007-08-01

    Demand response (DR) is increasingly recognized as an essential ingredient to well-functioning electricity markets. DR market potential studies can answer questions about the amount of DR available in a given area and from which market segments. Several recent DR market potential studies have been conducted, most adapting techniques used to estimate energy-efficiency (EE) potential. In this scoping study, we: reviewed and categorized seven recent DR market potential studies; recommended a methodology for estimating DR market potential for large, non-residential utility customers that uses price elasticities to account for behavior and prices; compiled participation rates and elasticity values from six DR options offered to large customers in recent years, and demonstrated our recommended methodology with large customer market potential scenarios at an illustrative Northeastern utility. We observe that EE and DR have several important differences that argue for an elasticity approach for large-customer DR options that rely on customer-initiated response to prices, rather than the engineering approaches typical of EE potential studies. Base-case estimates suggest that offering DR options to large, non-residential customers results in 1-3% reductions in their class peak demand in response to prices or incentive payments of $500/MWh. Participation rates (i.e., enrollment in voluntary DR programs or acceptance of default hourly pricing) have the greatest influence on DR impacts of all factors studied, yet are the least well understood. Elasticity refinements to reflect the impact of enabling technologies and response at high prices provide more accurate market potential estimates, particularly when arc elasticities (rather than substitution elasticities) are estimated.

    2009-01-01

    The National Energy Board regulates the construction and operation of interprovincial and international oil and gas pipelines and power lines as well as the tolls and tariffs for the pipelines under its jurisdictions. The import and export of natural gas is also regulated by the NEB. The NEB examined the possible energy futures that might unfold for Canadians up to the year 2020. The factors that affect the supply of crude oil, natural gas, liquefied natural gas, electricity and coal in the short term were examined to determine the outlook for deliverability through 2020. The growing demand for energy was reviewed along with the adequacy of future energy supplies, and related issues of emerging technologies, energy infrastructure and energy exports. This assessment provided separate production outlooks for hydrocarbons, electricity and coal and outlined the key uncertainties to the supply outlook. The likely impact of recent economic, energy and policy trends on energy demand and supply were considered. It was concluded that energy markets in Canada will continue to function well. Energy prices will provide appropriate market signals for the development of energy resources to meet Canadian and export demand. A significant portion of Canadian demand for energy will be met by fossil fuels. However, the demand to move towards greener energy fuels should result in fewer greenhouse gas emissions. 1 tab., 27 figs.

    2016-12-01

    Full Text Available This paper investigates the effect of increased demand-side flexibility (DSF on integration and market value of variable renewable energy sources (VRE. Using assumed potentials, system-optimal within-day shifts in demand are investigated for the Northern European power markets in 2030, applying a comprehensive partial equilibrium model with high temporal and spatial resolution. Increased DSF is found to cause only a minor (less than 3% reduction in consumers’ cost of electricity. VRE revenues are found to increase (up to 5% and 2% for wind and solar power, respectively, and total VRE curtailment decreases by up to 7.2 TWh. Increased DSF causes only limited reductions in GHG emissions. The emission reduction is, however, sensitive to underlying assumptions. We conclude that increased DSF is a promising measure for improving VRE integration. However, low consumers’ savings imply that policies stimulating DFS will be needed to fully use the potential benefits of DSF for VRE integration

    Full Text Available This article deals with an analysis of the world sugar market, and specifically focuses on the supply and demand of refined sugar and their main determinants. The article first identifies the main determinants of the world supply of and demand for sugar, and further, their effect on such variables is quantified. Further, the component correlations on the selected market are analyzed. This consists of the identification of the factors affecting the production of refined sugar, as one of the main elements of the supply of sugar, as well as an analysis of the world price of sugar, as one of the significant factors affecting the world sugar market. The said correlations are quantified with the utilization of regression analysis on the basis of time series of the individual variables within the years 1980–2010. On the basis of the conducted analysis, the main determinants of the sugar supply on the world market within the analyzed period, for which an effect has been established both from an economic viewpoint, as well as from a statistical viewpoint, can be considered to be sugar reserves, its price and the acreage of sugarcane. The main determinant of the demand for sugar is, according to the conducted analysis, the global GDP on a new value level, as well as converted to one inhabitant. Further, the analysis also established the effect of the price of sugar and its reserves on the world production of refined sugar, and, last but not least, also the long-term tendency in the development of the world price of sugar. The analysis has proven significant influence of refined sugar supply, reserves of refined sugar, its price and area of sugar cane on sugar supply. Then, the analysis detected GDP as the main determinant of the sugar demand and the long memory in sugar prices. Finally, the influence of delayed price, reserves and delayed reserves on production has been proven.

  12. Mackenzie Valley Pipeline market demand, supply, and infrastructure analysis : final report

    International Nuclear Information System (INIS)

    2004-01-01

    Mackenzie Valley Pipeline Co-Venturers is a consortium of petroleum companies proposing to construct a 1,400 km long, large-diameter, high-pressure natural gas transmission pipeline from the northwestern edge of the Northwest Territories to the Alberta-Northwest Territories border. The Mackenzie Valley Pipeline will bring natural gas from the Mackenzie Delta region to markets in Alberta, central and eastern Canada and the United States. Navigant Consulting Ltd. prepared this assessment of the long-term market need for natural gas produced from the Mackenzie Delta. It presents an analysis of gas demand, supply and infrastructure. Three sensitivity cases were examined, incorporating different assumptions about the initial capacity of the pipeline, potential expansion of its capacity and different levels of gas demand in Canada and the United States. The report indicates that gas markets in North America support construction of the proposed 34 million cubic metre per day pipeline in the 2009 timeframe, with possible expansion in 2015 and 2020. It also indicates that there will be enough capacity on the intra-Alberta gas transmission system to accommodate the projected deliveries of Mackenzie Delta gas. The increase in gas demand is due to an increase in residential and commercial gas consumption, electric power generation and the energy intensive bitumen extraction and processing activities in the Alberta oil sands industry. 36 tabs., 56 figs

    2016-01-01

    Highlights: • A new probabilistic methodology, integrating DR in a distribution energy market is proposed. • The method can alleviate distribution network congestions. • This method based on D-LMPs allows cost savings for end-user customers. • Innovative thermal and shiftable loads Real Time control algorithms are also presented. - Abstract: In the field of electricity distribution networks and with the advent of smart grids and microgrids, the use of Distribution Locational Marginal Price (D-LMPs) in a Real Time (RT) distribution market managed by a Distribution System Operator (DSO) is discussed in presence of empowered residential end-users that are able to bid for energy by a demand aggregator while following Demand Response (DR) initiatives. Each customer is provided by a transactive controller, which reads the locational market signals and answers with a bid taking into account the user preferences about some appliances involved in DR activities and controlled by smart plugs-in. In particular, Heating Ventilation and Air Conditioning (HVAC) appliances and shiftable loads are controlled so that their consumption profile can be modified according to the price of energy. In order to assess the effectiveness of the proposed method in terms of energy and cost saving, an innovative probabilistic methodology for evaluating the impact of residential DR choices considering uncertainties related to load demand, user preferences, environmental conditions, house thermal behavior and wholesale market trends has been proposed. The uncertainties related to the stochastic variations of the variables involved are modeled by using the Monte Carlo Simulation (MCS) method. The combination of MCS and RT distribution market simulation based on D-LMPs are used to assess the operation and impact of the DR method over one month. Simulations results on an 84-buses distribution network confirmed that the proposed method allows saving costs for residential end-users and making

    ANTÔNIO CORDEIRO DE SANTANA

    Full Text Available ABSTRACT The aim of this work was to estimate the parameters associated to the demand for açaí pulp in the retail market of Belém. Multiple regression analysis was applied to identify the key variables that impact on product consumption and to estimate the price and income elasticities and cross demand. The econometric estimation method applied was the least squares to correct heteroscedastic variance problems. Results have shown that the demand for açaí pulp is price and income inelastic. Fish and cassava flour were confirmed as complementary products of strong influence on the decisions of consumers. Product quality, with regard to its association to Chagas disease, also revealed a strong influence on product choice for household consumption. Finally, the socio-economic benefit of açaí pulp was R$ 762.78 million per year.

    Energy models play an increasing role in the ongoing energy transition processes either as tools for forecasting potential developments or for assessments of policy and market design options. In recent years, these models have increased in scope and scale and provide a reasonable representation of the energy supply side, technological aspects and general macroeconomic interactions. However, the representation of the demand side and consumer behavior has remained rather simplistic. The objective of this paper is twofold. First, we review existing large-scale energy model approaches, namely bottom-up and top-down models, with respect to their demand-side representation. Second, we identify gaps in existing approaches and draft potential pathways to account for a more detailed demand-side and behavior representation in energy modeling.

    2010-01-01

    Recently, a massive focus has been made on demand response (DR) programs, aimed to electricity price reduction, transmission lines congestion resolving, security enhancement and improvement of market liquidity. Basically, demand response programs are divided into two main categories namely, incentive-based programs and time-based programs. The focus of this paper is on Interruptible/Curtailable service (I/C) and capacity market programs (CAP), which are incentive-based demand response programs including penalties for customers in case of no responding to load reduction. First, by using the concept of price elasticity of demand and customer benefit function, economic model of above mentioned programs is developed. The proposed model helps the independent system operator (ISO) to identify and employ relevant DR program which both improves the characteristics of the load curve and also be welcome by customers. To evaluate the performance of the model, simulation study has been conducted using the load curve of the peak day of the Iranian power system grid in 2007. In the numerical study section, the impact of these programs on load shape and load level, and benefit of customers as well as reduction of energy consumption are shown. In addition, by using strategy success indices the results of simulation studies for different scenarios are analyzed and investigated for determination of the scenarios priority. (author)

    2016-01-01

    Conventionally the required instantaneous balance generation-load is achieved by adjusting production to fit variable consumer demand. Nowadays, a significant and increasing segment of generation is renewable. But renewable production cannot be scheduled on request since its generation is dependent on nature (wind, sun, …). In this context, demand-side management (DSM) would help since it would be advisable for part of the flexibility to be provided by the demand. The integration of renewable production and demand-side management (DSM), are compared in this work for Spain throughout 2008–2014. First a qualitative model, based on the linearization of the wholesale market, is employed to explore some hypotheses. A set of scenarios are then examined to quantify the main effects on the market. The results show that DSM exhibits the best performance in terms of economic efficiency and environmental sustainability, as well as for the reduction of load peaks and losses in the system, what suggests the convenience of promoting plans for the replacement of equipment with other more efficient as well as the implementation of real-time tariffs. - Highlights: •The impact of the integration of renewable production versus DSM has been compared. •Merit-order effect related to energy efficiency and to load-shifting is identified. •Large industries achieve energy efficiency with less CAPEX than renewable generation. •Load-shifting cycle yields a reduction of the traded energy and the economic volume.

    2008-01-01

    We analyze the economic properties of the economic demand-response (DR) program in the PJM electricity market in the United States using DR market data. PJM's program provided subsidies to customers who reduced load in response to price signals. The program incorporated a 'trigger point', at a locational marginal price of $75/MWh, at or beyond which payments for load reduction included a subsidy payment. Particularly during peak hours, such a program saves money for the system, but the subsidies involved introduce distortions into the market. We simulate demand-side bidding into the PJM market, and compare the social welfare gains with the subsidies paid to price-responsive load using load and price data for year 2006. The largest economic effect is wealth transfers from generators to non price-responsive loads. Based on the incentive payment structure that was in effect through the end of 2007, we estimate that the social welfare gains exceed the distortions introduced by the subsidies. Lowering the trigger point increases the transfer from generators to consumers, but may result in the subsidy outweighing the social welfare gains due to load curtailment. We estimate that the socially optimal range for the incentive trigger point would be $66-77/MWh

    Before restructuring in the electricity industry, the primary decision-makers of the electricity market were deemed to be power generation and transmission companies, market regulation boards, and power industry regulators. In this traditional structure, consumers were interested in receiving...... electricity at flat rates while paying no attention to the problems of this industry. This attitude was the source of many problems, sometimes leading to collapse of power systems and widespread blackouts. Restructuring of the electricity industry however provided a multitude of solutions to these problems....... The most important solution can be demand response (DR) programs. This paper proposes an economic DR model for residential consumers in liberalized electricity markets to change their consumption pattern from times of high energy prices to other times to maximize their utility functions. This economic...

    Many changes in health care delivery, health legislation, and the physician workforce that affect the supply and demand for endocrinology services have occurred since the first published workforce study of adult endocrinologists in 2003. The objective of the study was to assess the current adult endocrinology workforce data and provide the first analysis of the pediatric endocrinology workforce and to project the supply of and demand for endocrinologists through 2025. A workforce model was developed from an analysis of proprietary and publicly available databases, consultation with a technical expert panel, and the results of an online survey of board-certified endocrinologists. The Endocrine Society commissioned The Lewin Group to estimate current supply and to project gaps between supply and demand for endocrinologists. A technical expert panel of senior endocrinologists provided context, clinical information, and direction. The following were measured: 1) the current adult and pediatric endocrinology workforce and the supply of and demand for endocrinologists through 2025 and 2) the number of additional entrants into the endocrinology work pool that would be required to close the gap between supply and demand. Currently there is a shortage of approximately 1500 adult and 100 pediatric full-time equivalent endocrinologists. The gap for adult endocrinologists will expand to 2700 without an increase in the number of fellows trained. An increase in the prevalence of diabetes mellitus further expands the demand for adult endocrinologists. The gap can be closed in 5 and 10 years by increasing the number of fellowship positions by 14.4% and 5.5% per year, respectively. The gap between supply and demand for pediatric endocrinologists will close by 2016, and thereafter an excess supply over demand will develop at the current rate of new entrants into the work force. There are insufficient adult endocrinologists to satisfy current and future demand. A number of proactive

  9. The integration of Price Responsive Demand into Regional Transmission Organization (RTO) wholesale power markets and system operations

    2010-01-01

    A number of states and utilities are pursuing demand response based on dynamic and time-differentiated retail prices and utility investments in Advanced Metering Infrastructure (AMI), often as part of Smart Grid initiatives. These developments could produce large amounts of Price Responsive Demand, demand that predictably responds to changes in wholesale prices. Price Responsive Demand could provide significant reliability and economic benefits. However, existing RTO tariffs present potential barriers to the development of Price Responsive Demand. Effectively integrating Price Responsive Demand into RTO markets and operations will require changes in demand forecasting, scarcity pricing reform, synchronization of scarcity pricing with capacity markets, tracking voluntary hedging by price responsive loads, and a non-discriminatory approach in curtailments in capacity emergencies. The article describes changes in RTO policies and systems needed incorporate Price Responsive Demand. (author)

  10. Permanent demand excess as business strategy: an analysis of the Brazilian higher-education market

    2015-03-01

    Full Text Available Many Higher Education Institutions (HEIs establish tuition below the equilibrium price to generate permanent demand excess. This paper first adapts Becker’s (1991 theory to understand why the HEIs price in this way. The fact that students are both consumers and inputs on the education production process gives rise to a market equilibrium where some firms have excess demand and charge high prices, and others charge low prices and have empty seats.Second, the paper analyzes this equilibrium empirically. We estimated the demand for undergraduate courses in Business Administration in the State of São Paulo. The results show that tuition, quality of incoming students and percentage of lecturers holding doctorates degrees are the determining factors of students’ choice. Since the student quality determines the demand for a HEI, it is calculated what the value is for a HEI to get better students; that is the total revenue that each HEI gives up to guarantee excess demand. Regarding the “investment” in selectivity, 39 HEIs in São Paulo give up a combined R$ 5 million (or US$ 3.14 million in revenue per year per freshman class, which means 7.6% of the revenue coming from a freshman class.

    The complex production processes and long industrial chain in traditional Chinese medicine (TCM) market result in difficulty in Chinese market microstructure research. Based on the defining the logical relationships among different concepts. This paper divides TCM market into two stages as Chinese materia medica resource market and traditional Chinese Patent Medicines market. Under this foundation, we investigated the supply capacity, approaching rules and motivation system of suppliers in TCM market, analyzed the demand situation in the perspective of demand side, and evaluated the purchasing power in terms of population profile, income, and insurance. Furthermore we also analyzed the price formation mechanism in two stages of TCM market. We hope this study can make a positive and promotion effect on TCM market related research.

  12. Game design as marketing: How game mechanics create demand for virtual goods

    2010-01-01

    Full Text Available Selling virtual goods for real money is an increasingly popular revenue model for massively-multiplayer online games (MMOs, social networking sites (SNSs and other online hangouts. In this paper, we argue that the marketing of virtual goods currently falls short of what it could be. Game developers have long created compelling game designs, but having to market virtual goods to players is a relatively new situation to them. Professional marketers, on the other hand, tend to overlook the internal design of games and hangouts and focus on marketing the services as a whole. To begin bridging the gap, we propose that the design patterns and game mechanics commonly used in games and online hangouts should be viewed as a set of marketing techniques designed to sell virtual goods. Based on a review of a number of MMOs, we describe some of the most common patterns and game mechanics and show how their effects can be explained in terms of analogous techniques from marketing science. The results provide a new perspective to game design with interesting implications to developers. Moreover, they also suggest a radically new perspective to marketers of ordinary goods and services: viewing marketing as a form of game design.

    During the last decade, China has evolved into the largest consumer by far and one of the largest importers of coal. The main driver for the increase in coal demand in China has been economic growth. Future Chinese growth rates, and therefore coal consumption and coal imports, are highly uncertain, which may affect profitability of new investments of international mining companies. Furthermore, China has actively employed an array of instruments to control coal trade flows in the last years. In this paper, we analyse the potential impact of increased Chinese coal import volatility and of potential exertion of Chinese market power on global mining investment decisions. For this purpose, we develop a multi-stage stochastic equilibrium model which is able to simulate investments under uncertainty and a monopolistic player in addition to a competitive fringe. We find that accounting for Chinese demand uncertainty yields significant costs for investors and also leads to a delay in investments. Additionally, the exertion of Chinese market power further reduces overall investment activity.

    2010-12-01

    We show that the current economic crisis has led the market to exhibit a non-critical behavior. We do so by analyzing the quantitative parameters of time series from the main assets of the Brazilian Stock Market BOVESPA. By monitoring global persistence we show a deviation of power law behavior during the crisis in a strong analogy with spin systems (from where this concept was originally conceived). Such behavior is corroborated by an emergent heavy tail of absolute return distribution and also by the magnitude autocorrelation exponent. Comparisons with universal exponents obtained in the international stock markets are also performed. This suggests how a thorough analysis of suitable exponents can bring a possible way of forecasting market crises characterized by non-criticality.

    Health insurance companies curb price-insensitive behavior and the moral hazard of insureds by means of cost-sharing, such as tiered co-payments or reference pricing in drug markets. This paper evaluates the effect of price limits - below which drugs are exempt from co-payments - on prices and on demand. First, using a difference-in-differences estimation strategy, we find that the new policy decreases prices by 5 percent for generics and increases prices by 4 percent for brand-name drugs in the German reference price market. Second, estimating a nested-logit demand model, we show that consumers appreciate co-payment exempt drugs and calculate lower price elasticities for brand-name drugs than for generics. This explains the different price responses of brand-name and generic drugs and shows that price-related co-payment tiers are an effective tool to steer demand to low-priced drugs.

    How large is the potential demand for bio-heat in the UK? Whilst most research has focused on the supply of biomass for energy production, an understanding of the potential demand is crucial to the uptake of heat from bioenergy. We have designed a systematic framework utilising market segmentation techniques to assess the potential demand for biomass heat in the UK. First, the heat market is divided into relevant segments, characterised in terms of their final energy consumption, technological and fuel supply options. Second, the key technical, economic and organisational factors that affect the uptake of bioenergy in each heat segment are identified, classified and then analysed to reveal which could be strong barriers, which could be surmounted easily, and for which bioenergy heat represents an improvement compared to alternatives. The defined framework is applied to the UK residential sector. We identify provisionally the most promising market segments for bioenergy heat, and their current levels of energy demand. We find that, depending on the assumptions, the present potential demand for bio-heat in the UK residential sector ranges between 3% (conservative estimate) and 31% (optimistic estimate) of the total energy consumed in the heat market.

    An unceasing growth of gas consumption in domestic households, industry, and power plants has gradually turned natural gas into a major source of energy. Main drivers in this development are the technical and economic advantages of natural gas. It is a clean, versatile, and easily controllable fuel. On this basis, natural gas is often considered the form of energy that will be the 'bridging fuel' to a sustainable energy system, sometime after 2050. Unlike other main sources of energy, such as oil and coal, gas is not traded on an actual world market. This paper provides an overview on demand and supplies of natural gas (LNG) in the past as a function of gas prices, gas technology (gas sweetening, liquefaction, shipping and re-gasification), and gas market and how they have changed recently. It also discusses the likely developments in global LNG demand for the period to the year 2030. - Highlights: → This study provides an overview on demand and supplies of LNG in the past and future. → Outlook for LNG demand in Asia pacific region is very robust. → In past decade the shale gas production in USA has increased fivefold. → The future of European gas supply depends largely on the geopolitical environments. → Within the gas sector LNG is playing an ever increasing role in gas transportation.

    The Symposium was organized by the Energy Research Institute of the State Economic Commission of China, and the Lawrence Berkeley Laboratory and Johns Hopkins University from the United States. It was held at the Johns Hopkins University Nanjing Center in late June 1988. It was attended by about 15 Chinese and an equal number of US experts on various topics related to energy demand and supply. Each presenter is one of the best observers of the energy situation in their field. A Chinese and US speaker presented papers on each topic. In all, about 30 papers were presented over a period of two and one half days. Each paper was translated into English and Chinese. The Chinese papers provide an excellent overview of the emerging energy demand and supply situation in China and the obstacles the Chinese planners face in managing the expected increase in demand for energy. These are matched by papers that discuss the energy situation in the US and worldwide, and the implications of the changes in the world energy situation on both countries. The papers in Part 1 provide historical background and discuss future directions. The papers in Part 2 focus on the historical development of energy planning and policy in each country and the methodologies and tools used for projecting energy demand and supply. The papers in Part 3 examine the pattern of energy demand, the forces driving demand, and opportunities for energy conservation in each of the major sectors in China and the US. The papers in Part 4 deal with the outlook for global and Pacific region energy markets and the development of the oil and natural gas sector in China.

    Lewis, L.E.

    1990-01-01

    Studies have shown that the success of demand management programs, which have demonstrated economic benefits, depends on the level of customer participation. In order to have a better understanding of the decisionmaking process of commercial customers with respect to demand management programs, a study was undertaken to determine the preferences and the behavior of this class of clientele. This clientele, whose power consumption has been increasing at a faster rate than that of other sectors, represents a vast range of enterprises producing and supplying all kinds of products. Many of them operate from numerous geographic points on local, regional, national, and even world scales and are generally hierarchically organized. Because of these characteristics, their decisionmaking processes and their needs are equally complex, more so than in the residential sector. A multidimensional approach has been adopted to ensure that their needs are determined according to a quantitative and qualitative research method. The conclusions of the quantitative research have demonstrated that the frameworks representing different organizations respond differently to questions on their needs. It is also noted that certain commercial enterprises are of a cohesive nature (i.e. there is a consistency in understanding of corporate strategic and operational requirements at all hierarchical levels), while others are more diffuse. Those responsible for marketing demand management programs therefore must improve their understanding of the strategic and operational needs of their commercial customers in order to make their demand management programs productive in the view of the appropriate personnel at the hierarchical level applicable to the company concerned

    2001-01-01

    Tremendous political pressure is being exerted on the US government by different political parties to diversify its sources of foreign oil supplies by switching from the reliance on OPEC's oil to that originating from non-OPEC nations. Without a doubt, such a shift would adversely impact the market share of some OPEC members, particularly Saudi Arabia, Venezuela and Nigeria. These countries should therefore consider seriously the negative impact of this scenario and consequently formulate individual or joint production policies aiming at protecting their oil market share. To help OPEC achieve this objective, there is a need to estimate the demand function of US oil imports. This paper proffers an estimate of such a function, taking into account, among other variables, the impact of US Strategic Petroleum Reserve (SPR)

    The aim of this paper is to show the economic potential of demand response (DR) on household level at Central European market conditions. Thereby, required economic benefits for consumers' participation, the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed. The core of this paper builds a case-study applying spot market-oriented load shifting from the supplier's point of view by using Austrian electricity market data, household load profiles as well as a heat pump and e-car charging load profile. It is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level. Furthermore, upper cost limits for intelligent infrastructure in order to break-even are derived. Results suggest to take a critical look at European discussions on DR implementation on household level, showing that at Central European market conditions the potential for DR at household level is restricted to significant loads and hence, the applied load shifting strategy is only beneficial with application to heat pumps. In contrast, the frequently discussed shifting of conventional household devices' loads (such as washing machines) economically does not add up. - Highlights: • Calculation of economic potential of domestic DR at Central European market conditions. • Model and case-study of spot market-oriented load shifting from supplier's perspective. • Derivation of supplier's cost savings and upper cost limits for ICT infrastructure. • Results show economic potential of domestic DR to be restricted to significant loads. • Shifting of washing machines economically does not pay off in contrast to heat pumps

    This study seeks to minimize financial cost related to the price stabilization and the supply and demand stabilization. In order to accomplish this, it derives a theoretical model of supply hedging to minimize fluctuation risk of price and financial cost intended for crude oil and LNG. Through the positive analysis based on this, it analyzes quantitatively the economic effect of utilizing foreign futures market. It shows the decline of average and divergence of supply cost. Despite the economic effect of utilizing a futures market, the degree of utilizing energy futures market of related firms in Korea appeared to be insufficient. To raise the utilization of trading in futures, the followings were suggested. Firstly, cost reduction and sharing relating information can be designed through the joint participation among allied enterprises. Secondly, energy futures transaction center in Korea can be established or trading linkage based on the existing international trading system can be built. Thirdly, it is possible to subsidize related cost by making a loan from trading in futures. Lastly, the participating directly in a futures market at government level can be considered.

    1997-01-30

    This paper explains effects of market liberalization which will lead to introducing competition in electric power business on demand-side management (DSM), by quoting examples mainly in the United States. The paper also describes the future outlook thereon. The DSM program in the United States has expanded for the period between 1989 through 1994. However, during the last few years, the movements of electric power market liberalization have come to force electric power business entities to change their management strategies and reduction in expense. This situation has resulted in reduction in the DSM budget. Future DSM programs are thought to diversify into the following types: a program such as load management which has effect of reducing expenses and investments in investment time periods of 5 to 10 years, a program effective for users such as high-efficiency motors which have effects of reducing expenses and improving efficiency in investment time periods of 3 to 5 years, a program which will be effective enough if market barriers are removed after the market conversions, but requires subsidies and purchase guarantees, and a social program intended for environmental effects and low-income users. 4 refs., 1 tab.

    Full Text Available Introduction. Modern insurance companies provide the formation of effective market mechanisms for attracting investment resources to the national economy through the effective functioning of the insurance market with the use of modern market infrastructure and financial instruments. In Ukraine, the insurance market has a significant development potential, which requires, first of all, a detailed assessment of all available opportunities for balanced development in the context of European integration processes. Therefore, the identification and analysis of modern trends in the development of the insurance market are relevant today from theoretical and practical points of view. The purpose of the study is to analyze the current state of the insurance market in Ukraine and determine the factors affecting the effectiveness of its activities. Results. It was defined that the insurance market is the second largest in terms of capitalization among other non-bank financial markets in Ukraine. The tendencies of changes in the main indicators of the insurance market activity, in particular regarding the number of concluded insurance contracts, insurance premiums and insurance payments, reinsurance, insurance reserves, insurers’ assets and authorized capital, were investigated. It was found that the increase in gross insurance premiums was made for almost all types of insurance, and the increase of gross insurance premiums was mainly due to auto insurance, medical insurance and financial risk insurance. Nowadays, the level of insurance penetration in Ukraine is still low. However, according to the Comprehensive Program for the Development of the Financial Sector of Ukraine, a gradual increase of this indicator is planned. Conclusions. The conducted studies indicate that the insurance market of Ukraine is at the stage of formation, gradually adapting to the requirements of European and world markets. In order to improve the situation, domestic insurers

    This paper try to identify and examined the degree of market power on wheat international market by 2 major exporting countries comprising Canada and Australia by using the Pricing to Market (PTM) method and Residual Demand Elasticity (RDE) method. The PTM method found that Canada impose noncompetitive strategy by applying price discrimination and apply market power to their importing. Different results come from Australian exporter as they are not using their market power to the importing. Conflicting result arise from estimation using RDE and PTM method suggest that the need to extend the theoretical model of both model by expand its economic and econometric model to have consistent expected result theoretically and empirically.

    2016-09-01

    Full Text Available This paper investigates deregulation of electricity market focusing on electricity prices and drivers of demand for electrical energy in industry in Slovenia. The patterns in evolution of real electricity price developments and the three main components of the electricity price are calculated: liberalized market share for purchased electricity price, regulated infrastructure share for use of electricity network grids and mandatory state charges in the sale of electricity (duty, excise duty and value-added tax. To calculate the real value of electricity prices, producer price index of industrial commodities for electricity prices in industry is used as deflator and implicit deflator of gross domestic product for the size of the economy. In the empirical econometric part is used regression analysis for the amount electricity consumption in the industry depending on the real gross domestic product, direct and cross-price elasticity for natural gas prices in the industry. The results confirmed volatility in real electricity price developments with their increasing tendency and the increasing share of different taxes and state charges in the electricity prices for industry. Demand for electrical energy in industry is positively associated with gross domestic product and price of natural gas as substitute for electrical energy in industry use, and negatively associated with prices of electrical energy for industry.

  12. Impacts of demand response and renewable generation in electricity power market

    Science.gov (United States)

    Zhao, Zhechong

    This thesis presents the objective of the research which is to analyze the impacts of uncertain wind power and demand response on power systems operation and power market clearing. First, in order to effectively utilize available wind generation, it is usually given the highest priority by assigning zero or negative energy bidding prices when clearing the day-ahead electric power market. However, when congestion occurs, negative wind bidding prices would aggravate locational marginal prices (LMPs) to be negative in certain locations. A load shifting model is explored to alleviate possible congestions and enhance the utilization of wind generation, by shifting proper amount of load from peak hours to off peaks. The problem is to determine proper amount of load to be shifted, for enhancing the utilization of wind generation, alleviating transmission congestions, and making LMPs to be non-negative values. The second piece of work considered the price-based demand response (DR) program which is a mechanism for electricity consumers to dynamically manage their energy consumption in response to time-varying electricity prices. It encourages consumers to reduce their energy consumption when electricity prices are high, and thereby reduce the peak electricity demand and alleviate the pressure to power systems. However, it brings additional dynamics and new challenges on the real-time supply and demand balance. Specifically, price-sensitive DR load levels are constantly changing in response to dynamic real-time electricity prices, which will impact the economic dispatch (ED) schedule and in turn affect electricity market clearing prices. This thesis adopts two methods for examining the impacts of different DR price elasticity characteristics on the stability performance: a closed-loop iterative simulation method and a non-iterative method based on the contraction mapping theorem. This thesis also analyzes the financial stability of DR load consumers, by incorporating

    The renewable energy sources are promoted by their beneficial use, namely: - diversification of energy sources for producing electric power; - reduction of pollution produced by fossil fuel burning; - reduction of gas releases producing the greenhouse effects, etc. Currently, most of the renewable energy sources cannot concur on electric power free market because of the high costs of implied investments. To ensure an efficient use of renewable energy sources in electricity production and to maintain the installations implied on the electric power market, it is necessary to implement a system able to produce an output greater than that obtained from electric energy selling. The Romanian Government chose to promote the electric energy production by renewable energy sources by using the green certificate trading system. This system ensures the progress in developing the technologies employed in electric energy production from renewable energy sources and, at the same time the costs implied by their promotion can be adjusted by market mechanisms what will reduce the effects upon the electric energy consumers. The paper presents the legislation frame existing in Romania for promoting the electric energy produced from renewable energy sources, the green certificate trading system applied in Romania, as well as, the role shared by the entities implied in operation and development of the system.

  15. Uranium in the new world market: a statistical update of supply and demand 1991-2010

    International Nuclear Information System (INIS)

    1992-10-01

    The Uranium Institute first issued a statistical update to its biennial report on the uranium market in 1990. It was felt then that certain parameters in the supply-demand equation had changed significantly and that therefore the main data should be reviewed. Since publication of the 1991 report, Uranium in the New World Market, the changes have not been as far-reaching, nevertheless some trends have been confirmed, while others have been reversed. More information has also come to light from Eastern Europe, Commonwealth of Independent States (CIS) and China. Unforeseen developments since the 1991 report include the major revision of Ontario Hydro's plans which resulted in the deferral of additional power plants, the decision to complete the Philippine's mothballed reactor, the announcement of North Korea's nuclear programme and most recently the decision to suspend construction of Cuba's nuclear power plant and to put its nuclear programme on hold indefinitely. In order to evaluate the potential impact of these and other events on the uranium market, key statistical data have been reviewed. The data were collected in early 1992. The main changes since the 1991 report are summarized. The revisions have resulted in changes in the forecasts; the forecast nuclear generating capacity has been revised downwards, the forecast reactor requirements for western countries in 2000 have increased slightly whereas for 2000 there is almost no change.

  16. Maternity Leave Policies: Trade-Offs Between Labour Market Demands and Health Benefits for Children.

    Strang, Lucy; Broeks, Miriam

    2017-01-01

    Over recent years many European Union countries have made changes to the design of the maternity leave provision. These policy developments reflect calls for greater gender equality in the workforce and more equal share of childcare responsibilities. However, while research shows that long period of leave can have negative effects on women's labour market attachment and career advancements, early return to work can be seen as a factor preventing exclusive breastfeeding, and therefore, potentially having negative health impacts for babies. Indeed, the World Health Organisation recommends exclusive breastfeeding up to 6 months of age to provide babies with the nutrition for healthy growth and brain development, protection from life-threatening ailments, obesity and non-communicable diseases such as asthma and diabetes. Therefore, labour market demands on women may be at odds with the health benefits for children gained by longer periods of maternity leave. The aim of this article is to examine the relationship between leave provision and health benefits for children. We examine maternity and parental leave provision across European countries and its potential impact on the breastfeeding of very young babies (up to 6-months of age). We also consider economic factors of potential extension of maternity leave provision to 6 months, such as costs to businesses, effects on the female labour market attachment, and wider consequences (benefits and costs) for individuals, families, employers and the wider society.

    Full Text Available Stingless bees (kelulut keeping is now a trend in Malaysia. However, since demand for the source of colony in log is increasing, the log price is rapidly increasing. But, there is no data reported on the economic viability of meliponiculture in the current market price. Thus, the objective of this study is to clarify the economic viability of investment in meliponiculture in the current market price by engineering economic perspective. Investment in meliponiculture was analysed using Equivalent Annual Uniform Cost (EAUC, Internal Rate of Return (IRR and Breakeven Analysis. A small start-up with 30 units of logs or hives was considered in the analysis. All raw data was acquainted from current Malaysian market price, but only revenue from honey was considered. It was found that EAUC indicated that the annual worth of the log system is 23% better than the hive system. However, IRR calculation indicated that both the log and the hive systems offer margin exceeding 55% which is a very good return in general investment. In addition, it was also found that the log system had breakeven after 8th month, whereas the hive was 13th month. Better economic value could be obtained if revenue from by-products are considered. Thus, it can be concluded that meliponiculture is still very economically viable in Malaysia market trend, and the hive systems could be a better choice if splitting colony, maintenance, safety and aesthetics points of view are considered.

  2. Study on the complexity pricing game and coordination of the duopoly air conditioner market with disturbance demand

    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.

  3. Demand for natural gas: residential and commercial markets in Ontario and British Columbia. [Econometric-model analysis

    1977-02-01

    An econometric model is used to project natural gas demand in the residential and commercial market sectors. The model specification is a generalization of one developed by Balestra and Nerlove (Econometrica, 34: 585-612(1966)). Demand that is potentially variable because it is not committed to past investments (flexibe demand) is distinguished from demand that is inflexible because it is tied to existing equipment stocks (captive demand). Attention is focused on the effect of temperature variations on gas demand. The nonlinear equation system is estimated by a maximum-likelihood method, using annual data for British Columbia and Ontario during the period of 1959 to 1974. Results show that only in the long run does price have a significant impact on demand. The model is applicable for medium-term policy simulation, but is limited to natural gas fuel. 15 references.

  4. The future of the photovoltaic market (demand side/supply side)

    1998-01-01

    At present the main PV application market sectors are communications, leisure, boating, solar home systems, and water pumping. It is predicted that in the future, the largest photovoltaic market segments will be solar home photovoltaic systems, grid-connected small-scale photovoltaic systems, grid-connected medium-to-large scale photovoltaic systems, the communications sector and in the electrification of remote and isolated areas. The main factors favoring photovoltaic technology in remote and isolated areas result from: the high costs of conventional energy sources in remote locations; the loss of a scale-economy effect, which means specific costs of small photovoltaic systems are not much higher than those of larger photovoltaic systems; price of fuel, fuel transportation and spare part supplies. The major factors inhibiting the photovoltaic technology include high initial costs, lack of skilled man power, lack of good quality data and social acceptance. A roof top mounted photovoltaic system is one type of PV system which has attracted lots of interest among the people of north America and Europe. The generation of electricity by this system is attractive because: generation is on-site. This results in reduction of transmission costs and transmission losses; the cost of roofing tiles can be eliminated by using mounted PV systems instead; there is no need for additional land for power generation; visual impacts are limited. The objective of this paper is to review the development of the photovoltaic market in the recent 10 year period and discuss the future markets for this technology with respect to supply and demand

    Following the deregulation experience of retail electricity markets in most countries, the majority of the new entrants of the liberalized retail market were pure REP (retail electricity providers). These entities were subject to financial risks because of the unexpected price variations, price spikes, volatile loads and the potential for market power exertion by GENCO (generation companies). A REP can manage the market risks by employing the DR (demand response) programs and using its' generation and storage assets at the distribution network to serve the customers. The proposed model suggests how a REP with light physical assets, such as DG (distributed generation) units and ESS (energy storage systems), can survive in a competitive retail market. The paper discusses the effective risk management strategies for the REPs to deal with the uncertainties of the DAM (day-ahead market) and how to hedge the financial losses in the market. A two-stage stochastic programming problem is formulated. It aims to establish the financial incentive-based DR programs and the optimal dispatch of the DG units and ESSs. The uncertainty of the forecasted day-ahead load demand and electricity price is also taken into account with a scenario-based approach. The principal advantage of this model for REPs is reducing the risk of financial losses in DAMs, and the main benefit for the whole system is market power mitigation by virtually increasing the price elasticity of demand and reducing the peak demand. - Highlights: • Asset-light electricity retail providers subject to financial risks. • Incentive-based demand response program to manage the financial risks. • Maximizing the payoff of electricity retail providers in day-ahead market. • Mixed integer nonlinear programming to manage the risks

    This study estimates current and projects future neurologist supply and demand under alternative scenarios nationally and by state from 2012 through 2025. A microsimulation supply model simulates likely career choices of individual neurologists, taking into account the number of new neurologists trained each year and changing demographics of the neurology workforce. A microsimulation demand model simulates utilization of neurology services for each individual in a representative sample of the population in each state and for the United States as a whole. Demand projections reflect increased prevalence of neurologic conditions associated with population growth and aging, and expanded coverage under health care reform. The estimated active supply of 16,366 neurologists in 2012 is projected to increase to 18,060 by 2025. Long wait times for patients to see a neurologist, difficulty hiring new neurologists, and large numbers of neurologists who do not accept new Medicaid patients are consistent with a current national shortfall of neurologists. Demand for neurologists is projected to increase from ∼18,180 in 2012 (11% shortfall) to 21,440 by 2025 (19% shortfall). This includes an increased demand of 520 full-time equivalent neurologists starting in 2014 from expanded medical insurance coverage associated with the Patient Protection and Affordable Care Act. In the absence of efforts to increase the number of neurology professionals and retain the existing workforce, current national and geographic shortfalls of neurologists are likely to worsen, exacerbating long wait times and reducing access to care for Medicaid beneficiaries. Current geographic differences in adequacy of supply likely will persist into the future.

  12. Evaluating whether direct-to-consumer marketing can increase demand for evidence-based practice among parents of adolescents with substance use disorders: rationale and protocol.

    Science.gov (United States)

    Becker, Sara J

    2015-02-10

    Fewer than one in 10 adolescents with substance use disorders (ASUDs) will receive specialty treatment, and even fewer will receive treatment designated as evidence-based practice (EBP). Traditional efforts to increase the utilization of EBP by ASUDs typically focus on practitioners-either in substance use clinics or allied health settings. Direct-to-consumer (DTC) marketing that directly targets parents of ASUDs represents a potentially complementary paradigm that has yet to be evaluated. The current study is the first to evaluate the relevance of a well-established marketing framework (the Marketing Mix) and measurement approach (measurement of perceived service quality [PSQ]) with parents of ASUDs in need of treatment. A mixed-methods design is employed across three study phases, consistent with well-established methods used in the field of marketing science. Phase 1 consists of formative qualitative research with parents (and a supplementary sample of adolescents) in order to evaluate and potentially adapt a conceptual framework (Marketing Mix) and measure of PSQ. Phase 2 is a targeted survey of ASUD parents to elucidate their marketing preferences, using the adapted Marketing Mix framework, and to establish the psychometric properties of the PSQ measure. The survey will also gather data on parents' preferences for different targeted marketing messages. Phase 3 is a two-group randomized controlled trial comparing the effectiveness of targeted marketing messages versus standard clinical information. Key outcomes will include parents' ratings of PSQ (using the new measure), behavioral intentions to seek out information about EBP, and actual information-seeking behavior. The current study will inform the field whether a well-established marketing framework and measurement approach can be used to increase demand for EBP among parents of ASUDs. Results of this study will have the potential to immediately inform DTC marketing efforts by professional organizations

    Omagari, Yuko; Sugihara, Hideharu; Tsuji, Kiichiro

    This paper evaluates the economic impact of the introduction of customer-owned Thermal Storage Air-conditioning (TSA) systems, in an electricity market, from the viewpoint of the load service entity. We perform simulations on the condition that several thousand customers install TSA systems and shift peak demand in an electricity market by one percent. Our numerical results indicate that the purchase cost of the LSE was reduced through load management of customers with TSA systems. The introduction of TSA systems also reduced the volatility of market clearing price and reduced the whole-trade cost in an electricity market.

  15. Market modeling for assessment of demand side programs using the marginal cost

    International Nuclear Information System (INIS)

    Papastamatiou, Panagiotis; Psarras, John

    2000-01-01

    Demand side management is nowadays considered as a functional step in the energy planning process. The criteria proposed for the assessment of the demand side programs (DSPs) are usually based on the balance between the marginal supply cost and the mean DSP cost. These criteria could not support the allotting of the invested capital to incentives for the consumers and advertising. This paper presents a methodology to support the utility planning at this point with more reliability. It proposes the expansion of the assessment criteria with the use of the marginal cost of the DSP. For the calculation of the DSP marginal cost, a dynamic model is developed and it is used for the simulation of the penetration of a DS Program. Using the 'least-cost' criterion as the decision rule for the simulation, the planner has a distribution of the available investment capital throughout the whole planning period. The use of the 'most-value' criterion supports the separation of the invested capital between incentives for the consumers and supportive expenses, e.g. advertising, marketing cost, etc. (Author)

    Wang, Junping; Wang, Shengdong; Min, Jie

    2015-03-01

    In this paper, we study the optimal two-stage advertising and ordering policies and the channel coordination issues in a supply chain composed of one manufacturer and one retailer. The manufacturer sells a short-life-cycle product through the retailer facing stochastic demand in dynamic markets characterised by price declines and product obsolescence. Following a two-period newsvendor framework, we develop two members' optimal ordering and advertising models under both the centralised and decentralised settings, and present the closed-form solutions to the developed models as well. Moreover, we design a two-period revenue-sharing contract, and develop sufficient conditions such that the channel coordination can be achieved and a win-win outcome can be guaranteed. Our analysis suggests that the centralised decision creates an incentive for the retailer to increase the advertising investments in two periods and put the purchase forward, but the decentralised decision mechanism forces the retailer to decrease the advertising investments in two periods and postpone/reduce its purchase in the first period. This phenomenon becomes more evident when demand variability is high.

    Animals neither negotiate verbally nor conclude binding contracts, but nevertheless regularly exchange goods and services without overt coercion and manage to arrive at agreements over exchange rates. Biological market theory predicts that such exchange rates fluctuate according to the law of supply and demand. Previous studies showed that primates pay more when commodities become scarcer: subordinates groomed dominants longer before being tolerated at food sites in periods of shortage; females groomed mothers longer before obtaining permission to handle their infants when there were fewer newborns and males groomed fertile females longer before obtaining their compliance when fewer such females were present. We further substantiated these results by conducting a 2-step experiment in 2 groups of free-ranging vervet monkeys in the Loskop Dam Nature Reserve, South Africa. We first allowed a single low-ranking female to repeatedly provide food to her entire group by triggering the opening of a container and measured grooming bouts involving this female in the hour after she made the reward available. We then measured the shifts in grooming patterns after we added a second food container that could be opened by another low-ranking female, the second provider. All 4 providers received more grooming, relative to the amount of grooming they provided themselves. As biological market theory predicts, the initial gain of first providers was partially lost again after the introduction of a second provider in both groups. We conclude that grooming was fine-tuned to changes in the value of these females as social partners.

    2013-03-01

    Full Text Available Purpose: With the rapid development of economy and the support of government policy, the development of the logistics industry has become a new economic growth engine. As we all know, the reasonable price of logistics service is the most critical factor for logistics enterprises to win market share and make profit. At the same time, the service level is one of the most important factors which will influence the size of the market share. Therefore, this paper constructs a pricing model considering a situation that the logistics service level affects the market demand. This model helps the enterprises to make scientific decisions.Methodology: To achieve this objective, this paper constructs the TPL service and the pricing decision models based on the game theory.Findings: The conclusion shows that under the situation of independent decision-making, the enterprise which has strong ability of logistics service does not necessarily have a competitive advantage, while pricing equilibrium under the situation of joint decision-making, not only make both sides get more income, but also be conducive to improve the level of service.Research limitations: In this research, there are some assumptions that might affect the accuracy the model such as there are only two TPL enterprises to participate in, and considerations are taken under the condition of complete information environment. These assumptions can be relaxed in the future work.Originality: In this research, logistics service level is taken account into the areas of logistics service pricing, which makes the models more practical and more perfect. And this paper constructs game models based on game theory to make up the limitations of traditional pricing theories in logistics service pricing.

  20. A bilevel model for electricity retailers' participation in a demand response market environment

    2013-01-01

    Demand response programmes are seen as one of the contributing solutions to the challenges posed to power systems by the large-scale integration of renewable power sources, mostly due to their intermittent and stochastic nature. Among demand response programmes, real-time pricing schemes for small consumers are believed to have significant potential for peak-shaving and load-shifting, thus relieving the power system while reducing costs and risk for energy retailers. This paper proposes a game theoretical model accounting for the Stackelberg relationship between retailers (leaders) and consumers (followers) in a dynamic price environment. Both players in the game solve an economic optimisation problem subject to stochasticity in prices, weather-related variables and must-serve load. The model allows the determination of the dynamic price-signal delivering maximum retailer profit, and the optimal load pattern for consumers under this pricing. The bilevel programme is reformulated as a single-level MILP, which can be solved using commercial off-the-shelf optimisation software. In an illustrative example, we simulate and compare the dynamic pricing scheme with fixed and time-of-use pricing. We find that the dynamic pricing scheme is the most effective in achieving load-shifting, thus reducing retailer costs for energy procurement and regulation in the wholesale market. Additionally, the redistribution of the saved costs between retailers and consumers is investigated, showing that real-time pricing is less convenient than fixed and time-of-use price for consumers. This implies that careful design of the retail market is needed. Finally, we carry out a sensitivity analysis to analyse the effect of different levels of consumer flexibility. - Highlights: ► We model the game between electricity retailers and consumers under dynamic pricing. ► The retailer cuts procurement costs by shifting demand in time via price-incentive. ► Imbalance costs for the retailer taper

  1. Strategic and Tactical Design of Competing Decentralized Supply Chain Networks with Risk-Averse Participants for Markets with Uncertain Demand

    Directory of Open Access Journals (Sweden)

    Ashkan Hafezalkotob

    2011-01-01

    Full Text Available An integrated equilibrium model for tactical decisions in network design is developed. We consider a decentralized supply chain network operating in markets under uncertain demands when there is a rival decentralized chain. The primary assumption is that two chains provide partial substitutable products to the markets, and markets' demands are affected by tactical decisions such as price, service level, and advertising expenditure. Each chain consists of one risk-averse manufacturer and a set of risk-averse retailers. The strategic decisions are frequently taking precedence over tactical ones. Therefore, we first find equilibrium of tactical decisions for each possible scenario of supply chain network. Afterwards, we find optimal distribution network of the new supply chain by the scenario evaluation method. Numerical example, including sensitivity analysis will illustrate how the conservative behaviors of chains' members affect expected demand, profit, and utility of each distribution scenario.

    World hunger and the latest increases in global food prices are mainly dealt with by measures aimed at boosting supply and allowing markets to function more effectively. Motivated by the persistence of world hunger, we do not intend to contribute to either theory or empirical analysis in economics; we rather aim to show that current research and policies are locked in a sort of scientific paradigm which takes as given our dietary preferences, which are in fact fundamental in creating resource...

  6. Effect of policy-based bioenergy demand on southern timber markets: A case study of North Carolina

    Abt, Robert C.; Abt, Karen L.; Cubbage, Frederick W.; Henderson, Jesse D.

    2010-01-01

    Key factors driving renewable energy demand are state and federal policies requiring the use of renewable feedstocks to produce energy (renewable portfolio standards) and liquid fuels (renewable fuel standards). However, over the next decade, the infrastructure for renewable energy supplies is unlikely to develop as fast as both policy- and market-motivated renewable energy demands. This will favor the use of existing wood as a feedstock in the first wave of bioenergy production. The ability to supply wood over the next decade is a function of the residual utilization, age class structure, and competition from traditional wood users. Using the North Carolina Renewable Portfolio Standard as a case study, combined with assumptions regarding energy efficiency, logging residual utilization, and traditional wood demands over time, we simulate the impacts of increased woody biomass demand on timber markets. We focus on the dynamics resulting from the interaction of short-run demand changes and long-term supply responses. We conclude that logging residuals alone may be unable to meet bioenergy demands from North Carolina's Renewable Portfolio Standard. Thus, small roundwood (pulpwood) may be used to meet remaining bioenergy demands, resulting in increased timber prices and removals; displacement of traditional products; higher forest landowner incomes; and changes in the structure of the forest resource.

    Marketing-stimulated word-of-mouth (WOM) marketing has been poorly understood in health care, leading to it being underappreciated and underutilized by marketers. A study of new patients to a new runner's clinic was conducted to understand how they chose the program. The importance of marketing-stimulated WOM, both individual and organizational, is documented. Marketing-stimulated WOM is an often overlooked and rarely measured channel for increasing the impact of marketing programs.

    The German energy policy debate is currently focusing on different design options for a capacity mechanism. With VKU and BDEW, two leading associations in which almost all German energy market actors are represented, have positioned themselves in favor of a decidedly market-based capacity mechanism. The position of the VKU is based on the study ''A sustainable energy market design for Germany'', which was presented in March 2013. The following article describes the state of the energy market design debate in Germany and summarizes the proposed market design resulting from the VKU study. (orig.)

    Full Text Available Today, nanotechnology has become one of the strategic directions of economic development of the leading countries. According to literary sources, it is established that more than 50 countries of the world are adopting national programs in this field of new knowledge, and various methods of nanotechnology have received the greatest development and application in microelectronics, aerospace, chemical, medical, pharmaceutical and cosmetic industries. It should be noted, that beauty is the most represented products with the use of nanotechnologies in the world. On the evaluation of the European Commission in 2009, the specific weight of cosmetics with nanoparticles amounted to 5%. The aim of the work was to assess the current trends of the market nanocosmetic photoprotectors development. In the last years in Ukraine the market of cosmetics is developing dynamically. Manufacturers of medical cosmetics invest heavily in scientific researches, patents, improvement of existing technologies. To determine the status of the security of the pharmaceutical market of Ukraine, we have analyzed the volume of sales and range of medical cosmetics, presented at the domestic market. In terms of sales volume in money terms of therapeutic cosmetics every year loses its position. Thus, the volume of sales in 2011, has decreased on 1,1 % in comparison with 2009. In Ukraine cosmetics of native production occupies 8% of the total volume of sales, cosmetics of foreign production - 92%. At the next stage of the research we have analyzed the medical cosmetic means, which are used for the prevention of photo-aging of the skin. In General, the Ukrainian market of medicinal cosmetics contains 125 trademarks of foreign and native manufacture. The largest share in the market of Ukraine belongs to the French medical cosmetics - 48,6 % of the total number of medical cosmetic means. It is represented by the various lines of medical cosmetics brands such: Vichy, Avene, RoC, Uriage

    Lee, Sungkyu; Lee, Kelley; Holden, Chris

    2014-05-01

    To analyse the tactics transnational tobacco companies (TTCs) used to increase market share in South Korea after market liberalisation in 1988, and the subsequent impact of TTCs' activities on the domestic industry and ultimately public health. Internal tobacco industry documents were searched iteratively and analysed by keyword related to strategies for increasing market share in Korea since liberalisation. Following market liberalisation, TTCs faced entrenched cultural and institutional barriers in Korea which hindered increased sales of cigarette imports. TTCs identified population groups more favourably inclined towards imported brands, developed new distribution channels and used promotional activities targeting these groups. The growth in market share by TTCs suggests that these activities were successful at challenging the Korea Tobacco & Ginseng Corporation (KTGC) monopoly. In response, KTGC shifted to a proactive marketing approach and adopted strategies similar to TTCs. This, in turn, made the Korean market highly competitive. Findings show that, after market liberalisation, there was an upward trend in cigarette consumption and smoking prevalence among the targeted population groups, notably youth and young women. Governments engaging in trade negotiations that may lead to the opening of domestic tobacco markets need a fuller understanding of previous industry activities for expanding into emerging markets as well as how the domestic industry can change accordingly. To protect public health, the adoption of comprehensive tobacco control measures, guided by WHO Framework Convention on Tobacco Control, are needed as part of such negotiations.

    2016-01-01

    This paper proposes a methodology to optimize the trading strategies of a proactive distribution company (PDISCO) in the real-time market by mobilizing the demand response. Each distribution-level demand is considered as an elastic one. To capture the interrelation between the PDISCO and the real......-time market, a bi-level model is presented for the PDISCO to render continuous offers and bids strategically. The upper level problem expresses the PDISCO's profit maximization, while the lower-level problem minimizes the operation cost of the transmission-level real-time market. To solve the proposed model......, a primal-dual approach is used to translate this bi-level model into a single-level mathematical program with equilibrium constraints. Results of case studies are reported to show the effectiveness of the proposed model. (C) 2016 Elsevier Ltd. All rights reserved....

  15. Generation of predictive price and trading volume patterns in a model of dynamically evolving free market supply and demand

    Directory of Open Access Journals (Sweden)

    J. K. Wang

    2001-01-01

    Full Text Available I present a model of stock market price fluctuations incorporating effects of share supply as a history-dependent function of previous purchases and share demand as a function of price deviation from moving averages. Price charts generated show intervals of oscillations switching amplitude and frequency suddenly in time, forming price and trading volume patterns well-known in market technical analysis. Ultimate price trends agree with traditional predictions for specific patterns. The consideration of dynamically evolving supply and demand in this model resolves the apparent contradiction with the Efficient Market Hypothesis: perceptions of imprecise equity values by a world of investors evolve over non-negligible periods of time, with dependence on price history.

    Prince, D.

    2006-01-01

    Alberta-based Altex Energy Ltd. is pursuing the development of an innovative heavy oil/bitumen pipeline from Alberta to the United States Gulf Coast (USGC). This energy infrastructure development company is led by a proven management team that developed and constructed the 3,700 km long Alliance Pipeline system. This presentation included a map of the $3.7 billion dollar Alliance Pipeline that identified the mainline compressor stations, lateral compressor stations, area offices and head offices. It was noted that oilsands will represent the most significant resource plays for many years. A graph indicating bitumen supply forecasts from 2005 to 2020 suggests that bitumen production will have exponential growth over the foreseeable future. Labor, materials and infrastructure limitations will create barriers to oilsands growth, as will uncertain market access. For that reason, assured pipeline capacity is needed along with an infrastructure to refineries and a favourable competitive balance for Canadian producers. The presentation addressed issues regarding marketing choices and the challenges of upgrading in Alberta. The economics of diluting heavy oil was also discussed along with industry response to the diluent challenge. Altex's proposed solution of a new direct greenfield pipeline from Alberta to the USGC would reach the largest refinery market in North America as well as the largest heavy oil/bitumen consuming regions. The Altex solution would be complementary to heavy oil/bitumen in Alberta. The proprietary pipeline technology permits alternative diluents, eliminating much of the diluent penalty. It mitigates the risks of upgrading in Alberta and competes on a cost basis with other expansion alternatives. The Altex pipeline system eliminates the need for costly condensate diluent, but accepts all current diluents. It transports up to 90 per cent more bitumen than clean diluted bitumen in a conventional pipeline. It can also transport as much as 175 per cent

    2017-08-07

    This paper presents the first publicly available comprehensive survey of the magnitude of demand charges for commercial customers across the United States -- a key predictor of the financial performance of behind-the-meter battery storage systems. Notably, the analysis estimates that there are nearly 5 million commercial customers in the United States who can subscribe to retail electricity tariffs that have demand charges in excess of $15 per kilowatt (kW), over a quarter of the 18 million commercial customers in total in the United States. While the economic viability of installing battery energy storage must be determined on a case-by-case basis, high demand charges are often cited as a critical factor in battery project economics. Increasing use of demand charges in utility tariffs and anticipated future declines in storage costs will only serve to unlock additional markets and strengthen existing ones.

  1. Current status and outlook for the methanol market in the United States

    International Nuclear Information System (INIS)

    Grigsby, B.J.

    1995-01-01

    During the past year, announcements regarding new methanol capacity have been too numerous to mention. Current producers are looking to increase capacity by debottlenecking or by adding additional capacity. Methanol consumers have announced plans to build new methanol plants or re-open older plants that had been shut down. While these new announcements would certainly seem adequate to supply any new demand that may be coming on-line, still other companies without prior methanol producing experience are looking to invest in new plants. This is not a situation occurring just in the US. All over the world new methanol capacity is being discussed. However, the topic of this paper involves only the US methanol market. If all the new capacity that has been announced does come on-line in the next two to three years, the methanol industry could be in for some very lean times. The demand picture for methanol looks to be strong with a healthy growth rate forecast. However, a growth in demand like that of the past three years should not be expected. Most of that growth came from the dramatic increases in MTBE capacity since the CAAA were announced

    The HyFrance3 project has provided a national framework for reflection, debate and strategic exchange between major public and industrial research players, namely for their hydrogen technology arms in France (Air Liquide, Total Refining and Marketing, EDF R and D, GDF SUEZ, CNRS-LEPII Energies Nouvelles, AFH2, ALPHEA, ADEME (co-financing and partner) and the CEA (coordinator). This project focuses on studying the landscape, trends and economic competitiveness of some links in the hydrogen chain, for industrial and energy applications, over a period referred to as 'short term' (2020-2030). Four study subjects were tackled: the prospective demand for hydrogen in industry (analysis of the current situation and outlook for 2030, in particular for refining based on two scenarios on mobility), production of hydrogen for transport uses from wind-produced electricity, mass storage that would have to be set up in the Rhone Alpes and PACA regions, to balance supply that is subject to deliberate (maintenance) or involuntary interruptions, and the distribution of hydrogen in the region, for automobile use (gas station network in the Rhone Alpes and PACA regions) by 2050 (with end period all-in costs between 0.4 eur/kg and 0.6 eur/kg, as a function of the price of energy and the distance from the storage site).

  3. An Economic Evalution of Demand-side Energy Storage Systems by using a Multi-agent based Electricity Market

    Science.gov (United States)

    Furusawa, Ken; Sugihara, Hideharu; Tsuji, Kiichiro

    Opened wholesale electric power market in April 2005, deregulation of electric power industry in Japan has faced a new competitive environment. In the new environment, Independent Power Producer (: IPP), Power Producer and Supplier (: PPS), Load Service Entity (: LSE) and electric utility can trade electric energy through both bilateral contracts and single-price auction at the electricity market. In general, the market clearing price (: MCP) is largely changed by amount of total load demand in the market. The influence may cause price spike, and consequently the volatility of MCP will make LSEs and their customers to face a risk of revenue and cost. DSM is attracted as a means of load leveling, and has effect on decreasing MCP at peak load period. Introducing Energy Storage systems (: ES) is one of DSM in order to change demand profile at customer-side. In case that customers decrease their own demand at jumped MCP, a bidding strategy of generating companies may be changed their strategy. As a result, MCP is changed through such complex mechanism. In this paper the authors evaluate MCP by multi-agent. It is considered that customer-side ES has an effect on MCP fluctuation. Through numerical examples, this paper evaluates the influence on MCP by controlling customer-side ES corresponding to variation of MCP.

    Marketing is widely recognized as an essential business function across all industries, including healthcare. While many long-term care facilities adopted basic healthcare marketing practices and hired marketing staff by the early 1990s, a paucity of research on nursing home marketing exists in the literature. This study examines the extent to which nursing homes have developed more formulated marketing and related communication and promotional strategies as market competition has increased in this sector during the past two decades. In addition, we explored managers' perceptions of their control over marketing decision making, the impact of competition on the use of marketing practices, and areas for enhanced competitive positioning. Administrators from 230 nursing homes in 18 Southeastern Michigan counties were surveyed regarding (1) the adoption level of approximately 40 literature-based, best-practice marketing strategies; (2) the types of staff involved with the marketing function; and (3) their perception of their level of control over marketing functions and of local competition. Results from 101 (44 percent) survey participants revealed that although respondents viewed their markets as highly competitive, their marketing practices remained focused on traditional and relatively constrained practices. In relation to the importance of customer relationship management, the majority of the administrators reported intensive efforts being focused on residents and their families, referrers, and staff, with minimal efforts being extended to insurers and other types of payers. A significant positive relation was found between the intensity of marketing initiatives and the size of the facility (number of beds), whereas significant negative correlations were revealed in relation to occupancy and the perceived level of control over the function.

    2015-01-01

    This paper presents a methodology for the identification, analysis and comparative assessment of the handicaps which nowadays prevent the higher implementation of Demand Response (DR) in the electricity market. Its application provides a hierarchical organization of handicaps from the most critical to the less critical and then, from the easiest to the most difficult to overcome. This makes possible to determine which barriers would be a priority, which may indicate the direction of regulatory changes to properly address these handicaps and so, stimulating a higher participation of the demand side in electricity markets. After applying the methodology to three European countries, 34 handicaps have been identified, analyzing which of these handicaps affect such stakeholders as grid operators, retailers and customers and how these stakeholders are affected. For each handicap, the criticality and difficulty to overcome the different handicaps have been studied, based on detailed information coming from personal interviews to experts representing the different stakeholders in the electricity trading chain. Regulatory barriers have been identified as the most critical and difficult to overcome. Together with regulatory changes, the promotion of aggregators and the training of customers on DR applications are some of the most significant initiatives. - Highlights: • Market handicaps prevent the application of Demand Response in electricity markets. • A methodology to identify and organize such market handicaps has been developed. • The evaluation and quantification of criticality and difficulty to overcome is done. • A hierarchical list prioritizing handicaps to be addressed is obtained. • Market handicaps of three European countries were evaluated through this methodology.

    Power Market players of developing countries with supply deficit are exposed to a unique combination of price risk and quantity risk which is not the case with developed nations that have taken path of liberalization to open up their power markets. India has one of the largest generation capacities in the world, yet till recently the Indian Power sector was highly regulated. However, the last decade has witnessed many initiatives so as to make the sector market oriented. This paper provides opportunity for developing countries to learn from Indian experience of introducing competition in the power sector.

    1988-03-01

    Applicable uses and the market size for photovoltaic (PV) systems were investigated taking into consideration the features and economics of such systems. As a result of computing representative usage examples together with the extent of potential demand for PV, 238 GW for the power source in private homes, 76 GW for green houses, 126 GW for sewage water treatment plants, 4 GW for schools and universities and others were estimated. For the greater number of PV systems already in actual use, non-cost factors acted as major determining factors when deciding on implementation. Promising uses (applicable ideas) seen from the standpoint of non-cost factors were studied in order to develop the PV system market and gain breakthrough for lowering future costs and increasing proliferation for such systems. When it comes to simultaneously decreasing costs and increasing demand for solar batteries in the coming days, it will be impossible to make an immediate transition from the present state of demand for public use and for special use to the final goal of demand as a power source in the home. There is a need for an intermediate demand that can bridge this gap. (13 figs, 9 tabs)

  8. Integration of Methodologies for the Evaluation of Offer Curves in Energy and Capacity Markets through Energy Efficiency and Demand Response

    2018-02-01

    Full Text Available The objectives of improving the efficiency, and integration, of renewable sources by 2030–2050 are complex in practice and should be linked to an increase of demand-side flexibility. The main challenges to achieving this flexibility are the lack of incentives and an adequate framework. For instance, customers’ revenue is usually low, the volatility of prices is high and there is not any practical feedback to customers from smart meters. The possibility of increasing customer revenue could reduce the uncertainty with respect to economic concerns, improving investments in efficiency, enabling technology and thus, engaging more customers in these policies. This objective could be achieved by the participation of customers in several markets. Moreover, Demand Response and Energy Efficiency can share ICT technologies but this participation needs to perform an aggregation of demand. The idea of this paper is to present some methodologies for facilitating the definition and evaluation of energy versus cost curves; and subsequently to estimate potential revenues due to Demand Response. This can be accomplished by models that estimate: demand and energy aggregation; economic opportunities and benefits; impacts on customer convenience; customer feedback and price analysis. By doing so, we would have comprehensive information that can help customers and aggregators to define energy packages and their monetary value with the objective of fostering their market participation.

  9. The long-term supply/demand trend of world energy and the current oil situation in the Asia

    International Nuclear Information System (INIS)

    1996-01-01

    Total world primary energy consumption excluding the FSU increased by 2.9% in 1995, which is somewhat above the 10 year average rate of 2.4%. This reflected strong economic growth in most parts of the world. The increase in demand confirmed the recovery of the link between the economic growth and consumption of primary energy, which broke down in the period of oil crises. Oil demand in the Asian Emerging Market Economies has continued to be very strong. Oil demand has doubled in a decade in this region and is now one sixth of world consumption. Malaysia was the fastest growing oil market in the world in 1995 at 15.5%. In volume terms, S. Korea grew the most in the world by 170,000 b/d, closely followed by China and India. Because of the fast growing oil demand, many energy economists expect a tight supply situation in the Asian oil market in the early 21st Century. However, recent technological developments would be able to supply crude oil appropriate for an increase in oil demand. (author)

    1991-01-01

    Under the series of Korean Government 5 year economic development plans since 1962, energy consumption in Korea has increased at a rapid pace and industrialization in Korea has been accelerated. As far as coal imports are concerned, coking coal was first imported to Korea in the early 1970s for the first steelworks. Little interest was shown in steaming coal until the early 1970s owing to the cheaper imported oil. People became interested in steaming coal after the first oil crisis in 1973 and import began in 1980 for cement and other industrial uses. In general, electricity demand is increasing far more rapidly than energy consumption. The initial construction of two 560 megawatt power plants using bituminous coal began in 1978 and was completed in 1982. The maiden cargo of bituminous coal for power generation arrived in Korea that year and coal import has been increasing at a rapid rate since then to keep pace with increased consumption. As there are no indigenous bituminous coal resources in Korea and we must depend entirely on overseas coal for our needs to fuel power plants, stable securing of coal is very important. This paper explains the current status and prospects for KEPCOs (Korean Electric Power Corporation) coal demand and supply

    Radioisotope and pharmaceutical kits play an important role in nuclear medicine for non-invasive diagnosis and treatment of various cancers and cardiovascular disease. Our aim was to survey the current utilization and future demand of radiopharmaceuticals and radioisotopes in Malaysia. The survey methodology technique was done using questionnaire administration modes. The survey was done for four month duration from government hospitals that have nuclear medicine department. The most frequent pharmaceutical kits used in hospitals were Methylene Diphosphonic acid (MDP) for bone imaging and Diethylene Triamine Pantacetic acid (DTPA). Similarly radioisotopes widely used were Tc-99m and Iodine 131.Therefore if produced of Tc-99m by Nuclear Malaysia can improved in term of high quality products, Nuclear Malaysia could be the sole supplier of this product to hospitals in Malaysia. Similarly pharmaceutical kits especially MDP and DTPA, Nuclear Malaysia has the expertise and knowledge to supply these kits to the hospital. (author)

  17. Electric Vehicles in Colorado: Anticipating Consumer Demand for Direct Current Fast Charging

    Energy Technology Data Exchange (ETDEWEB)

    Wood, Eric W. [National Renewable Energy Laboratory (NREL), Golden, CO (United States); Rames, Clement L. [National Renewable Energy Laboratory (NREL), Golden, CO (United States)

    2017-07-01

    To support the State of Colorado in planning for growth in direct current fast charging (DCFC) for electric vehicles, the National Renewable Energy Laboratory (NREL) has partnered with the Regional Air Quality Council (RAQC) and the Colorado Department of Transportation (CDOT) to analyze a number of DCFC investment scenarios. NREL analyzed existing electric vehicle registration data from IHS Markit (IHS) to highlight early trends in the electric vehicle market, which were compared with sales forecasts predicting large growth in the Colorado electric vehicle market. Electric vehicle forecasts were then used to develop future DCFC scenarios to be evaluated in a simulation environment to estimate consumer benefits of the hypothetical DCFC networks in terms of increased driving range and electric vehicle miles traveled (eVMT). Simulated utilization of the hypothetical DCFC networks was analyzed for geographic trends, particularly for correlations with vehicle electric range. Finally, a subset of simulations is presented for consumers with potentially inconsistent access to charging at their home location and presumably greater reliance on public DCFC infrastructure.

  19. Social Welfare implications of demand response programs in competitive electricity markets

    Energy Technology Data Exchange (ETDEWEB)

    Boisvert, Richard N.; Neenan, Bernard F.

    2003-08-01

    The price volatility exhibited by wholesale electricity markets has stymied the movement to restructure the industry, and may derail it altogether. Market designers argue that prices are superior to regulation for directing long-term investments to the proper location and function, and that price volatility is a natural manifestation of a robustly competitive market. However, episodes of prices that soar to previously unimaginable heights try customers' patience and cause policy makers to reconsider if the prize is worth the consequences.

    2004-01-01

    Natural Gas Liquids (NGL) price influences were reviewed in this presentation, as well as issues concerning North American propane demand and waterborne imports. A review of U.S. propane stocks was provided as well as regional temperature outlooks for 2004-2005. A cracking feedstock parity forecast was presented, as well as United States gross gas plant margins and propane prices to July 2005. Canadian propane inventories and prices were reviewed. A propane supply and demand forecast to 2020 was presented. Alberta's natural gas supply and intra-Alberta oil sand gas demand growth were discussed. Various market uncertainties include higher levels of activity; the potential of petroleum prices falling due to a reduction of geopolitical risk; the possibility of a U.S. recession; and the growth of Alberta's oil sands industry, with resulting demand for natural gas. It was concluded that the NGL market in North America will continue to be balanced, with waterborne imports becoming more critical. It was suggested that inventories are adequate for the expected winter season. It was also suggested that Canadian NGL supplies are expected to decline, and that prices are expected to soften in the spring of 2005, with falling natural gas and crude oil prices. refs., tabs., figs

  6. Demand Response in Europe's Electricity Sector: Market barriers and outstanding issues

    International Nuclear Information System (INIS)

    Eid, Cherrelle

    2015-01-01

    In October 2014, Europe's drive for sustainability has been further continued with the set objectives for 2030, aiming for 40% emission reduction compared to 1990 levels and at least a 27% share of renewable energy sources. For the longer term, the European Commission (EC) targets a zero CO_2 emitting electricity sector in 2050. Those objectives for the electricity sector have a large impact on the expected development of electricity generation, but also on the evolution of demand. To meet those objectives, a larger share of electricity supply will come from intermittent sources like wind turbines and solar panels. In an electric system that is largely based on renewable electricity sources, it is desired to have higher electricity consumption in moments when more renewable electricity is being produced, and a lower consumption in times of lower renewable production. Demand response is related to the adaptability of the electricity demand to the availability of supply. The development of demand response is rooted in the need for carbon emission reductions and for efficient use of installed generation capacities with the growth of power consumption. In addition to providing flexibility to the electric system, demand response could be a direct source of revenue to households and businesses. In 2013, in the United States, businesses and homeowners earned over $2.2 billion in revenues from demand response together with other avoided investment in grid infrastructure and power plants. This source of direct revenue could also be made available in Europe and would release financial benefits to local economies (SEDC, 2014). The reliability improvements as well as the economic and sustainability potential coming from a more responsive electricity demand are fully acknowledged. However, demand response is still immaturely developed in Europe. If Europe wants to make a step forward to a more sustainable electricity sector, the development of demand response is an inevitable

  8. Optimal Operation and Value Evaluation of Pumped Storage Power Plants Considering Spot Market Trading and Uncertainty of Bilateral Demand

    Science.gov (United States)

    Takahashi, Kenta; Hara, Ryoichi; Kita, Hiroyuki; Hasegawa, Jun

    In recent years, as the deregulation in electric power industry has advanced in many countries, a spot market trading of electricity has been done. Generation companies are allowed to purchase the electricity through the electric power market and supply electric power for their bilateral customers. Under this circumstance, it is important for the generation companies to procure the required electricity with cheaper cost to increase their profit. The market price is volatile since it is determined by bidding between buyer and seller. The pumped storage power plant, one of the storage facilities is promising against such volatile market price since it can produce a profit by purchasing electricity with lower-price and selling it with higher-price. This paper discusses the optimal operation of the pumped storage power plants considering bidding strategy to an uncertain spot market. The volatilities in market price and demand are represented by the Vasicek model in our estimation. This paper also discusses the allocation of operational reserve to the pumped storage power plant.

    Fries, M. D.; Allen, C. C.; Calaway, M. J.; Evans, C. A.; Stansbery, E. K.

    2015-01-01

    Curation of NASA's astromaterials sample collections is a demanding and evolving activity that supports valuable science from NASA missions for generations, long after the samples are returned to Earth. For example, NASA continues to loan hundreds of Apollo program samples to investigators every year and those samples are often analyzed using instruments that did not exist at the time of the Apollo missions themselves. The samples are curated in a manner that minimizes overall contamination, enabling clean, new high-sensitivity measurements and new science results over 40 years after their return to Earth. As our exploration of the Solar System progresses, upcoming and future NASA sample return missions will return new samples with stringent contamination control, sample environmental control, and Planetary Protection requirements. Therefore, an essential element of a healthy astromaterials curation program is a research and development (R&D) effort that characterizes and employs new technologies to maintain current collections and enable new missions - an Advanced Curation effort. JSC's Astromaterials Acquisition & Curation Office is continually performing Advanced Curation research, identifying and defining knowledge gaps about research, development, and validation/verification topics that are critical to support current and future NASA astromaterials sample collections. The following are highlighted knowledge gaps and research opportunities.

    2013-01-01

    Past and recent factors point to a remarkable growth of the Asian market in the medium and long term. This growth will depend on structural and institutional evolutions on the Asian market. Some regulatory and liberalization reforms have already been initiated to support the development of gas but this will require a long process. Oil-indexing will prevail for a long time (but which slope?) Supply flexibility must be improved (relaxation of destination clauses, quantity tolerances) to create a competitive gas market. Marketing innovations expected in new long-term contracts to enhance flexibility whilst preserving investment security. A growing portfolio approach (LNG portfolio, pipeline imports, unconventional gas) is implemented. In conclusion, regional cooperation among Asian buyers is very important

  12. Estimating deficit probabilities with price-responsive demand in contract-based electricity markets

    International Nuclear Information System (INIS)

    Galetovic, Alexander; Munoz, Cristian M.

    2009-01-01

    Studies that estimate deficit probabilities in hydrothermal systems have generally ignored the response of demand to changing prices, in the belief that such response is largely irrelevant. We show that ignoring the response of demand to prices can lead to substantial over or under estimation of the probability of an energy deficit. To make our point we present an estimation of deficit probabilities in Chile's Central Interconnected System between 2006 and 2010. This period is characterized by tight supply, fast consumption growth and rising electricity prices. When the response of demand to rising prices is acknowledged, forecasted deficit probabilities and marginal costs are shown to be substantially lower

    2012-01-01

    Full Text Available The global meat market and primarily the chicken meat market represents a very dynamically developing area. The objective of the present article is the analysis of the chicken meat market in the world in order to identify the basic development trends associated with the development of production of and trade in chicken meat, and also in order to identify the individual entities controlling the global chicken meat market. In methodological terms, the article analyzes the development of production of, consumption of and trade (export and import in chicken meat in the years 1961–2009. The main sources of data necessary for the processing of the individual analyses are the FAOSTAT and UN COMTRADE databases. The results of the conducted analysis show the following findings. World production of poultry meat increased from 7.5 million tons to more than 86 million tons. The global market reacted in a flexible manner, in which there was an increase in volumes of executed trade from 271 thousand tons/year in the year 1961 to more than 10.7 million tons/year in the year 2010. Further, the value of world trade in chicken meat within the analyzed period increased from approximately USD 169 million to approximately USD 16 billion. If we analyze the global chicken meat market, it may be stated that it is very concentrated. The analysis of the global market further shows that Brazil, the USA and China represent, in terms of global production, consumption and trade, the main driving force on the chicken meat market. These three countries have a share in global production of approximately 46%, their share in global consumption ranges at a level of over 40%. The share of these countries in global export ranges at a level exceeding 50%.

  16. Feasibility and potential of thermal demand side management in residential buildings considering different developments in the German energy market

    International Nuclear Information System (INIS)

    2016-01-01

    Highlights: • A scenario analysis for the German energy market in the year 2030 is performed. • Growing demand for flexible electric capacities is identified in all scenarios. • Significant potential for domestic demand side management is identified. • A distinct potential for dynamic operation of domestic supply systems is found. • The necessity for a quick introduction of smart metering and control is found. - Abstract: A transition in the electricity market is required to manage the volatility of increasing renewable energy generation. These fluctuations can be faced with flexible consumption through Demand Side Management (DSM), establishment of further centralized storage capacities and provisioning of dynamic back up generation capacities. At least the latter two options can impose large establishment and operation costs upon the electricity market. Therefore, the feasibility and the resulting potential of coupling the electricity grid with the thermal supply of residential buildings is analysed in this paper. Thereby, inexpensive and widespread thermal storage capacities could be used to improve the integration of dynamic renewable electricity generation. In this paper the technical and economical key impact factors for such thermal DSM approach are elaborated. Based on a literature review, the identified key factors are aggregated to form consistent scenarios of the German “Energiewende” (turnaround in energy policy). The practicability and possible magnitude of the intended DSM is then analysed based on the identified scenarios. All resulting scenarios highlight the growing demand for a flexible electricity market. Especially in scenarios with strong growth of renewable electricity generation, up to 45 GW of flexible electric capacities would be required in Germany by the year 2030. Furthermore, the analysis demonstrates that independently of the energy market development, it is very likely that electricity coupled supply systems will

    Nicholls, James

    2012-01-01

    To provide a snapshot content analysis of social media marketing among leading alcohol brands in the UK, and to outline the implications for both regulatory policies and further research. Using screengrab technology, the complete Facebook walls and Twitter timelines for 12 leading UK alcohol brands in November 2011 were captured and archived. A total of 701 brand-authored posts were identified and categorized using a thematic coding frame. Key strategic trends were identified and analysed in the light of contextual research into recent developments in marketing practice within the alcohol industry. A number of dominating trends were identified. These included the use of real-world tie-ins, interactive games, competitions and time-specific suggestions to drink. These methods reflect a strategy of branded conversation-stimulus which is favoured by social media marketing agencies. A number of distinct marketing methods are deployed by alcohol brands when using social media. These may undermine policies which seek to change social norms around drinking, especially the normalization of daily consumption. Social media marketing also raises questions regarding the efficacy of reactive regulatory frameworks. Further research into both the nature and impact of alcohol marketing on social media is needed.

    Consumer choice theory is a branch of microeconomics. This theory relates to adjusting consumption expenditures and consumer demand curve. Consumer choice science is trying to realize the buyer's decision-making process. This science studies customer characteristics, such as behavioral criteria......, to understand the consumer’s need. The concept of price elasticity of demand (PED) has also been derived from this theory. In fact, the PED is the percentage of changes in the amount of demand relative to the price changes. In consumer choice theory, for each consumer according to behavioral criteria, a unique...... demand response (DR) models have been developed based on this concept, this will also be deemed as a disadvantage for them.

  2. Two African woodfuel markets: urban demand, resource depletion, and environmental degradation

    International Nuclear Information System (INIS)

    Hosier, R.H.; Milukas, M.V.

    1992-01-01

    This paper examines charcoal markets in two African cities: Mogadishu, Somalia and Kigali, Rwanda. Economic theory dictates that if woodfuel resources become scarce, their real price will increase commensurately with the interest rate. Although Rwanda and Somalia represent drastically different physical environments, both are considered to be wood-scarce. But neither market has demonstrated straightforward depletion effects. In Mogadishu, the price first rose and then fell in reaction to shifts in the structure of the charcoal market, relaxed regulations, and economic contraction. In Rwanda, the price began rising only after the closing of the Bugasera Region to charcoal producers. Charcoal must be increasingly produced from private farmland. These two case studies highlight the importance of agricultural land clearance, conflicting government regulations, and shifts in market structure in determining whether or not charcoal prices will demonstrate depletion effects, and whether or not charcoal production will lead to local environmental degradation.

  3. The current state of the market for corporate acquisitions

    International Nuclear Information System (INIS)

    Korpach, A.N.

    1998-01-01

    The main factors which determine when the oil and gas industry is in a seller's market or a buyer's market mode were discussed. In a seller's market, the number of potential buyers for assets exceeds the number of sellers. Therefore, sellers could obtain good prices for their assets. Such was the case from 1995 to 1997. For 1998, the level of merger and acquisition activity was high and is expected to remain strong for 1999, but the market appears to be firmly a buyer's market (more sellers than potential buyers). The reasons for this are as follows: (1) restricted access to capital, (2) declining stock prices/values, (3) significant supply of assets, and (4) acquisition costs now in line with finding and development costs. The question of whether or not acquisitions add value was also discussed. It was noted that share price performance of those companies making acquisitions during the period was comparable to that of the TSE oil and gas producers index. A list of some Canadian and U.S. companies which completed significant acquisitions in 1997 and 1998 was included. 10 figs

  10. Demand Side Management in an Integrated Electricity Market: What are the Impacts on Generation and Environmental Concerns?

    International Nuclear Information System (INIS)

    Bergaentzle, Claire; Clastres, Cedric

    2013-05-01

    Smart Grid technology appears necessary to succeed in activating the demand through demand side management (DSM) programs. This would in turn improve energy efficiency and achieve environmental targets through controlled consumption. The many pilot projects led worldwide involving smart grids technology, brought quantitative evaluations of DSM measures on electricity load. Efficient DSM instruments must be fine-tuned to respond to very specific issues arising from the generation mix, the integration of intermittent energies or the level of outage risks faced during peak period. Efficient DSM strategies are illustrated through a model involving five countries that carry these different features and under the assumptions of isolated and fully interconnected markets. This paper aims at bringing recommendations regarding the instruments that should be implemented to maximize the benefits of smart grids technology and demand response. Finally, it tends to emphasis the issue of homogenized energy efficiency policies, critical in the building of internal energy markets such as the one the European Union is envisioning. (authors)

    Full Text Available The impact of inaccurate demand beliefs on dynamics of a Triopoly game is studied. We suppose that all the players make their own estimations on possible demand with errors. A dynamic Triopoly game with such demand belief is set up. Based on this model, existence and local stable region of the equilibriums are investigated by 3D stable regions of Nash equilibrium point. The complex dynamics, such as bifurcation scenarios and route to chaos, are displayed in 2D bifurcation diagrams, in which e1 and α are negatively related to each other. Basins of attraction are investigated and we found that the attraction domain becomes smaller with the increase in price modification speed, which indicates that all the players’ output must be kept within a certain range so as to keep the system stable. Feedback control method is used to keep the system at an equilibrium state.

    Demand management tools are population-based strategies used to control costs and improve utilization of services by assisting health consumers in maintaining their health and seeking appropriate health care. These tools are increasingly used by health care delivery systems and, in the US, by fiscal intermediaries, such as insurance companies. If these tools are not properly applied, there is a clear possibility that their use may lead a reduction of health care services with no improvement in clinical, humanistic, or economic outcomes. Demand management effectiveness has not been rigorously examined by the medical industry or academia. Before adopting or purchasing demand management technologies, health care systems should examine them carefully to determine how the tools were developed and who they were intended to serve. Once implemented, careful tracking of population outcomes is as necessary with these technologies as with any other technologies that can affect health care.

    Energy demand forecasts are often based on assumptions which are uncertain and dependent upon both political and economic factors. However, there is a need for long-term energy forecasting for the benefit of industry and commerce. CIRS (Cambridge Information and Research Services Limited) have tried to fulfill this need, based on forecasts of useful heat demand sector by sector which are then converted to heat energy supply and primary requirements. The first such forecast was produced in 1975. This 1983 updated projection examines coal, oil and gas supplies in the UK to the year 1995.

    1995-09-01

    International Energy Agency (IEA) experts met in Zurich in order to further develop international projects for the coordinated procurement of energy-saving technologies. On the occasion of this meeting, Swiss specialists from business and administrative circles presented examples of how the market can be purposefully influenced by implementing measures on the demand side. In order to ensure success, it is vital that all parties concerned - from the manufacturers to the consumers - are taken into account, and that tools are applied that have been adapted to each individual market. An international coordination of activities that are aimed at bringing about a change in procurement behaviour contributes considerably to an acceleration of the various processes. For the manufacturers, most of whom are active on an international level, it becomes simpler and more worthwhile to react. This applies in particular when instruments such as quality seals (labels) and target values are applied. (author) figs., tabs

  17. The Spanish Gas Market: Demand Trends Post Recession and Consequences for the Industry

    OpenAIRE

    2011-01-01

    In parallel with a flourishing economy, the natural gas industry in Spain was characterised by rapid consumption growth in the late 1990s and 2000s. Infrastructure and supplies were designed to meet the needs of a gas market growing at double digit rates each year. This high growth rate – for a European gas market – was expected to continue until at least the mid-2010s. By 2011, this outlook was replaced by a more pessimistic one. Firstly, the country’s economy was hit hard by the global rece...

  18. A deterministic model for deteriorating items with displayed inventory level dependent demand rate incorporating marketing decisions with transportation cost

    A. K. Bhunia

    2011-01-01

    Full Text Available This paper deals with an inventory model, which considers the impact of marketing strategies such as pricing and advertising as well as the displayed inventory level on the demand rate of the system. In addition, the demand rate during the stock-out period differs from that during the stock-in period by a function varied on the waiting time up to the beginning of the next cycle. Shortage are allowed and partially backlogged. Here, the deterioration rate is assumed to follow the Weibull distribution. Considering all these factors with others, different scenarios of the system are investigated. To obtain the solutions of these cases and to illustrate the model, an example is considered. Finally, to study the effects of changes of different parameters of the system, sensitivity analyses have been carried out with respect to the different parameters of the system.

  1. MARKET SUPPLY RESPONSE AND DEMAND FOR LOCAL RICE IN NIGERIA: IMPLICATIONS FOR SELF-SUFFICIENCY POLICY

    Directory of Open Access Journals (Sweden)

    M RAHJI

    2009-03-01

    Full Text Available This study examined the supply response and demand for local rice in Nigeria between 1960 and 2004. A system of equations using secondary data was estimated by OLS and 2SLS techniques. Area planted with local rice is mainly affected by expected price of output, agriculture wage rate and by the partial adjustment coefficient. The short-run response elasticity is 0.077. The implied long-run response elasticity is 1.578. The partial adjustment measure is 0.049. This, points to the difficulty of supply response to changing economic conditions. The price elasticity of demand obtained is 0.841. The demand for local rice is thus price inelastic. Rice income elasticity is 0.3378. It is also inelastic. The ban on rice importation in Nigeria could be said to be a step in the right direction. This policy should be continued and policed. However, price, output and non-price incentives that can exert significant influence on rice supply response and demand are required if the self-sufficiency goal is to be achieved.

    2000-01-01

    This first part of a series on developments in the European gas market features the growth in gas supply. 35% of the gas demand must be covered from sources outside Europe. For the future additional imports are required from countries such as the Russian Federation, Algeria and Nigeria. Over the next few years the artificial link between ga and oil prices will disappear, bringing the gas price to a structurally lower level. It will be of crucial importance that gas suppliers will not be able to form cartels to keep prices high. All competing projects will curb price increases on the European market, but will definitely result in more freedom of choice for European natural gas consumers

  7. Reducing domestic heating demand: Managing the impact of behavior-changing feedback devices via marketing.

    Science.gov (United States)

    Jensen, Thorben; Chappin, Émile J L

    2017-07-15

    Feedback devices can be used to inform households about their energy-consumption behavior. This may persuade them to practice energy conservation. The use of feedback devices can also-via word of mouth-spread among households and thereby support the spread of the incentivized behavior, e.g. energy-efficient heating behavior. This study investigates how to manage the impact of these environmental innovations via marketing. Marketing activities can support the diffusion of devices. This study aims to identify the most effective strategies of marketing feedback devices. We did this by adapting an agent-based model to simulate the roll-out of a novel feedback technology and heating behavior within households in a virtual city. The most promising marketing strategies were simulated and their impacts were analyzed. We found it particularly effective to lend out feedback devices to consumers, followed by leveraging the social influence of well-connected individuals, and giving away the first few feedback devices for free. Making households aware of the possibility of purchasing feedback devices was found to be least effective. However, making households aware proved to be most cost-efficient. This study shows that actively managing the roll-out of feedback devices can increase their impacts on energy-conservation both effectively and cost-efficiently. Copyright © 2017 Elsevier Ltd.

    To identify effective strategies for marketing pharmacist-provided medication therapy management (MTM) services to patients in a self-insured employer setting. Qualitative study. University of Pittsburgh during March through May 2008. 26 university employees taking at least one chronic medication. Three focus group sessions were conducted using a semistructured topic guide to facilitate the discussion. Employees' perceived medication-related needs, perceived benefits of pharmacist-provided MTM, potential barriers for employee participation in MTM, and effective strategies for marketing MTM. Participants reported concerns with timing of doses, medication costs, access, and ensuring adherence. Participants generally felt positively toward pharmacists; however, the level of reported patient contact with pharmacists varied among participants. Some participants questioned pharmacists' education and qualifications for this enhanced role in patient care. Perceived benefits of MTM noted by participants included the opportunity to obtain personalized information about their medications and the potential for improved communication among their health providers. Barriers to patient participation were out-of-pocket costs and lack of time for MTM visits. Participants suggested use of alternative words to describe MTM and marketing approaches that involve personal contact. Pharmacists should emphasize parts of MTM that patients feel are most beneficial (i.e., provision of a personal medication record) and use patient-friendly language to describe MTM when marketing their practice. Patients will need greater exposure to the concept of MTM and the pharmacists' role in order to correctly describe and assign value to this type of pharmacist patient care practice.

  16. An Agent-Based Labor Market Simulation with Endogenous Skill-Demand

    Science.gov (United States)

    Gemkow, S.

    This paper considers an agent-based labor market simulation to examine the influence of skills on wages and unemployment rates. Therefore less and highly skilled workers as well as less and highly productive vacancies are implemented. The skill distribution is exogenous whereas the distribution of the less and highly productive vacancies is endogenous. The different opportunities of the skill groups on the labor market are established by skill requirements. This means that a highly productive vacancy can only be filled by a highly skilled unemployed. Different skill distributions, which can also be interpreted as skill-biased technological change, are simulated by incrementing the skill level of highly skilled persons exogenously. This simulation also provides a microeconomic foundation of the matching function often used in theoretical approaches.

    Full Text Available The purpose of the research is to discover which employability skills may be developed by students from technical universities in order to meet market demands. Since graduates from technical universities face unemployment or over qualification for vacant jobs, we presumed that there is a misalignment between employers’ expectations concerning graduates’ skills and what they really get from school. Therefore, we conceived a questionnaire to see the demands of the business environment regarding graduates’ technical and professional skills. After analyzing the data, we proposed an interdisciplinary module system, where the mentors coming from the companies involved in the study teach voluntary or optional courses and applications in the domains where they have expertise. We used the employability skills model to find that mix of competencies that may help graduates find jobs in their field of knowledge. This innovative method serves universities, students and companies as well: the prestige of a university is quantified by the experts delivered into the labor market; companies will have well prepared employees in their specific area, with less costs; students will find jobs which will match their expectations, giving them motivation to perform. The limitation of the present research is that the study refers only to the Civil Engineering specialization of the Technical University Cluj-Napoca Romania.

    Highlights: • We compare two demand side management in a day-ahead electricity wholesale market. • We develop and reconcile social welfare & industrial DSM mathematical models. • We show the industrial netload has an additional forecast quantity of baseline. • We analytically and numerically show the model equivalence with accurate baseline. • We numerically demonstrate the baseline errors lead to higher and costlier dispatch. - Abstract: The intermittent nature of renewable energy has been discussed in the context of the operational challenges that it brings to electrical grid reliability. Demand side management (DSM) with its ability to allow customers to adjust electricity consumption in response to market signals has often been recognized as an efficient way to mitigate the variable effects of renewable energy as well as to increase system efficiency and reduce system costs. However, the academic & industrial literature have taken divergent approaches to DSM implementation. While the popular approach among academia adopts a social welfare maximization formulation, the industrial practice compensates customers according to their load reduction from a predefined electricity consumption baseline that would have occurred without DSM. This paper rigorously compares these two different approaches in a day-ahead wholesale market context analytically and in a test case using the same system configuration and mathematical formalism. The comparison of the two models showed that a proper reconciliation of the two models might make them mitigate the stochastic netload in fundamentally the same way, but only under very specific conditions which are rarely met in practice. While the social welfare model uses a stochastic net load composed of two terms, the industrial DSM model uses a stochastic net load composed of three terms including the additional baseline term. DSM participants are likely to manipulate the baseline in order to receive greater financial

  6. Meeting the near-term demand for hydrogen using nuclear energy in competitive power markets

    Miller, A.I.; Duffey, R.B.

    2004-01-01

    Hydrogen is becoming the reference fuel for future transportation and the timetable for its adoption is shortening. However, to deploy its full potential, hydrogen production either directly or indirectly needs to satisfy three criteria: no associated emissions, including CO 2 ; wide availability; and affordability. This creates a window of great opportunity within the next 15 years for nuclear energy to provide the backbone of hydrogen-based energy systems. But nuclear must establish its hydrogen generating role long before the widespread deployment of Gen IV high-temperature reactors, with their possibility of producing hydrogen directly by heat rather than electricity. For Gen IV the major factors will be efficiency and economic cost, particularly if centralized storage is needed and/or credits for avoided emissions and/or oxygen sales. In the interim, despite its apparently lower overall efficiency, water electrolysis is the only available technology today able to meet the first and second criteria. The third criterion includes costs of electrolysis and electricity. The primary requirements for affordable electrolysis are low capital cost and high utilisation. Consequently, the electricity supply must enable high utilisation as well as being itself low-cost and emissions-free. Evolved Gen III+ nuclear technologies can produce electricity on large scales and at rates competitive with today's CO 2 -emitting, fossil-fuelled technologies. As an example of electrolytic hydrogen's potential, we show competitive deployment in a typical competitive power market. Among the attractions of this approach are reactors supplying a base-loaded market - though permitting occasional, opportunistic diversion of electricity during price spikes on the power grid - and easy delivery of hydrogen to widely distributed users. Gen IV systems with multiple product streams and higher efficiency (e.g., the SCWR) can also be envisaged which can use competitive energy markets to advantage

    2013-06-01

    The size of the illicit drug market is an important indicator to assess the impact on society of an important part of the illegal economy and to evaluate drug policy and law enforcement interventions. The extent of illicit drug use and of the drug market can essentially only be estimated by indirect methods based on indirect measures and on data from various sources, as administrative data sets and surveys. The combined use of several methodologies and data sets allows to reduce biases and inaccuracies of estimates obtained on the basis of each of them separately. This approach has been applied to Italian data. The estimation methods applied are capture-recapture methods with latent heterogeneity and multiplier methods. Several data sets have been used, both administrative and survey data sets. First, the retail dealer prevalence has been estimated on the basis of administrative data, then the user prevalence by multiplier methods. Using information about behaviour of dealers and consumers from survey data, the average amount of a substance used or sold and the average unit cost have been estimated and allow estimating the size of the drug market. The estimates have been obtained using a supply-side approach and a demand-side approach and have been compared. These results are in turn used for estimating the interception rate for the different substances in term of the value of the substance seized with respect to the total value of the substance to be sold at retail prices.

In the first step, we used unstructured focus group interviews combined with a series of multiple-choice and open-ended questions for identifying product attributes and attribute levels that are relevant to consumers’ preferences. After the main attributes and the levels of attributes had been selected, they were combined to form different hypothetical product profiles. Obtained data were analyzed with the help of the conjoint analysis software. Findings: The results show that MP3 player manufacturers and sellers should focus their marketing strategies on the brand when targeting young people, as the most significant market segment for such products. The findings of the demand and price sensitivity analysis imply that the buyers of this product category are generally price-sensitive and therefore willing to switch brands. Limitations: While the study covered the most important attributes regarding MP3 players, it might be desirable to include design as an additional attribute as well as more brands. Also, a sample size could be increased to allow market segmentation based on the obtained part-worths.

  10. Russian Youth on Labour Market: ‘Portfolioability’ as New Desire and Demand

    Full Text Available This article contributes to the debate about portfolio and organizational careers and presents the results of qualitative research of Russian young employees. During perestroika, Soviet career structures were almost completely destroyed. This led to the fact that working population of post-Soviet Russia had to adapt to new structures and/or create new conditions to be able to work and to ensure security. Such local uncertainty and instability coincided with intensive globalisation of the national economy and society, which had an even stronger effect: local instability combined with global instability.The analysis of biographical interviews demonstrated that a lot of young Russians on contemporary labour market can be characterised by portfolioability—a property that unites young professionals with different type of employment. We mean by this term a kind of attitude towards work typical for Russian youth, which reflects inner flexibility, experience, transferable skills and multiple employment practices. Moreover, it is portfolioability that in some cases becomes a resource to improve security/confidence concerning the labour market, as well as to develop agency. Besides, the lack of portfolioability results in a more vulnerable position and dependence on conditions.

    This final report for the Swiss Federal Office of Energy describes the two concepts - 'resistive' and 'inductive' - used for Superconducting Fault Current Limiters (SCFCL) that utilise the transition from zero to finite resistance to limit short-circuit currents. The main advantages of SCFCL are compared to other current-limiting technologies: They can limit any type of prospective fault current, operate fail-safe, be self-triggered and self-restoring. Their main disadvantage - the cooling effort necessary - is also discussed. The application possibilities of SCFCL were investigated by simulating the impact on utility and industrial grids. Applications of SCFCL such as the coupling of medium-voltage grids and their use in series with a circuit-breaker on the secondary side of a substation transformer are discussed. It is also shown that, by using fault current limiters, considerable cost savings can be made, especially in connection with new installations or the extension of existing plants.

    Currently, the petroleum products market is totally regulated. The operations and pricing mechanism must be conducted under prevailing Government rules and regulations. Indeed, in Nigeria today, no industry is as regulated as the Oil Industry (downstream emphasised) - which constitute the totality of petroleum products market. This situation has arisen as a result of the seeming classification of the oil industry as being strategic. Due to the regulations of the market, it can no longer adapt to the changing economic trend of liberalization and interplay of market forces, even when under serious pressure to yield to the dynamics of free market enterprise. As a result of the resistance to change, the market becomes stressed and over-burdened by the shackles of regulation which leads to a breakdown of the system and the impact becomes noticeable almost immediately. Needless to emphasize that, for the petroleum products market to survive and thrive, a cursory look at what obtains currently would afford us the opportunity to access the strength and weaknesses of such system, with a view to ascertaining the survival strategy to be applied for sustainable growth. In addition, a serious examination of the roles being played by the key operators in the petroleum products market otherwise called down stream operators (refineries, pipelines and marketers) is imperative. Since it requires the co-operation of the operators to achieve synergy in the market, any bottleneck arising from any of the sub-sectors has the capacity to disrupt the system

    Biomass, organic wastes, hydroelectric power, wind power and solar energy contribute to approximately 6% of the current energy demand in the European Union (EU). Goals are set by the EU to double this share in the energy production in the next decade. The EU Altener Programme aims to increase the use of renewables as source of energy, the trade in renewable energy products and related equipment and services, supporting a wide variety of projects, sector and market studies, events and technical standards. The Agricultural and Forestrial Biomass Network (AFB-Nett) promotes and stimulates, as part of the Altener Programme, the implementation and commercial exploitation of energy from biomass by the initiation of among other things business opportunities and information exchange. The AFB-Nett National Coordinator for the Netherlands, Novem, organised in this respect the title seminar. 85 participants from several European countries attended presentations covering the whole bio-energy chain: from information on biomass supply, through trade, logistics and pretreatment issues up to discussion on conversion technologies. It became clear to the audience that it is a necessary condition to take into account the total chain when developing projects in a specific field of this chain. However, non-technical aspects must be considered as well. Therefore, in developing business opportunities the challenge remains to connect all good project initiatives covering parts of the chain into a few 'whole-chain'-projects

  15. Direct-to-consumer marketing of prescription drugs: a current perspective for neurologists and psychiatrists.

    2004-01-01

    In the US and New Zealand, the past decade has seen tremendous growth in the marketing of prescription drugs directly to patients. The pharmaceutical industry has applied pressure in other countries to relax regulations governing such marketing although this has not yet been successful. While we still have much to learn about the potential impact on the public's health of direct-to-consumer (DTC) marketing, some data are available. This article summarises the current literature on the benefits and risks of DTC marketing. This marketing strategy has grown substantially in the US, but only select drugs are advertised. Whether there is net benefit or harm to the public's health as a result of DTC marketing depends critically on which drugs are advertised and the quality of the information provided in promotional material. Critical reviews of this promotional material suggest the information is of poor quality. Notably, 18% of the 50 drugs advertised most intensively in the US were medications used to treat psychiatric and neurological disorders. The impairments in decisional capacity often seen in psychiatric and neurological illness leave patients vunerable to the controlling influence of DTC marketing and, thus, undermine the patient autonomy that is said to be promoted by this marketing strategy. If there is any benefit from DTC marketing it is for significantly undertreated conditions. International restrictions on DTC marketing should remain in place until further evidence of net benefit or harm emerges from the DTC marketing experiment that is taking place in the US and New Zealand.

    A recent pilot test to enable an Automatic Demand Response system in California has revealed several lessons that are important to consider for a wider application of a regional or statewide Demand Response Program. The six facilities involved in the site testing were from diverse areas of our economy. The test subjects included a major retail food marketer and one of their retail grocery stores, financial services buildings for a major bank, a postal services facility, a federal government office building, a state university site, and ancillary buildings to a pharmaceutical research company. Although these organizations are all serving diverse purposes and customers, they share some underlying common characteristics that make their simultaneous study worthwhile from a market transformation perspective. These are large organizations. Energy efficiency is neither their core business nor are the decision makers who will enable this technology powerful players in their organizations. The management of buildings is perceived to be a small issue for top management and unless something goes wrong, little attention is paid to the building manager's problems. All of these organizations contract out a major part of their technical building operating systems. Control systems and energy management systems are proprietary. Their systems do not easily interact with one another. Management is, with the exception of one site, not electronically or computer literate enough to understand the full dimensions of the technology they have purchased. Despite the research team's development of a simple, straightforward method of informing them about the features of the demand response program, they had significant difficulty enabling their systems to meet the needs of the research. The research team had to step in and work directly with their vendors and contractors at all but one location. All of the participants have volunteered to participate in the study for altruistic

  17. Demand response and energy efficiency in the capacity resource procurement: Case studies of forward capacity markets in ISO New England, PJM and Great Britain

    Demand-side resources like demand response (DR) and energy efficiency (EE) can contribute to the capacity adequacy underpinning power system reliability. Forward capacity markets are established in many liberalised markets to procure capacity, with a strong interest in procuring DR and EE. With case studies of ISO New England, PJM and Great Britain, this paper examines the process and trends of procuring DR and EE in forward capacity markets, and the design for integration mechanisms. It finds that the contribution of DR and EE varies wildly across these three capacity markets, due to a set of factors regarding mechanism design, market conditions and regulatory provisions, and the offering of EE is more heavily influenced by regulatory utility EE obligation. DR and EE are complementary in targeting end-uses and customers for capacity resources, thus highlighting the value of procuring them both. System needs and resources’ market potential need to be considered in defining capacity products. Over the long-term, it is important to ensure the removal of barriers for these demand-side resources and the capability of providers in addressing risks of unstable funding and forward planning. For the EDR Pilot in the UK, better coordination with forward capacity auction needs to be achieved. - Highlights: • Trends of demand response and energy efficiency in capacity markets are analysed. • Integration mechanisms, market conditions and regulatory provisions are key factors. • Participation of energy efficiency is influenced by regulatory utility obligations. • Procuring both demand response and energy efficiency in capacity market is valuable. • Critical analysis of the design of capacity products and integration mechanisms.

Thus, in 2014, only 16.7% of those who used the computer in the range of 16-74 years and 10% of the total population of the same age had made online purchases, compared with 63.3% and 50% respectively - the same indicators at EU level. Still, in Romania there was a rapid increase in the share of those who make online purchases, so in 8 years (2007-2014 this indicator increased by 3 times. Regarding the categories of the population by various characteristics, greater orientation towards online purchases is recorded among individuals with high formal education, youth (under 35, with above-average incomes. In terms of product categories purchased online, the most favorite categories are: clothes, sports goods. This analysis is based mostly on official statistics provided by Eurostat.

    Full Text Available Retail in large store-chains extended in well-developed countries. 465 millions inhabitants express their supply on their markets; between 2000 and 2005 sales values were increasing; the increase-sources were the promotional prices, as well as the European buyers' availability to respond to the supply's diversity. After the political events that happened after 1989, in Romania appeared large hypermarket-chains and supermarket-chains, most of them being transnational companies that developed their own business in our country. Due to these commercial-units, the retail-value in Romania grew in a spectacular way, with more than 85% during 2000-2005 period, although from the retail-value per inhabitant point of view, we are far behind other European countries' level. The number of retail-commercial units, as well as the sales-purchasing value in these units characterizes the commercial sector situation in a country. For a comparative analysis at territorial level, for different European Union's countries, we will realize a multicriterial hierarchy, based on the two statistical indicators previously mentioned, and on other two general macroeconomic indicators: Gross Domestic Product (GDP per inhabitant and unemployment-rate. The main European Union's countries hierarchy based on the four criteria was realized by two statistical methods: the ranks' method and the relative-distance method from the maximum performance unit.

  2. Meeting the near-term demand for hydrogen using nuclear energy in competitive power markets

    International Nuclear Information System (INIS)

    Miller, Alistair I.; Duffey, Romney B.

    2004-01-01

    Hydrogen is becoming the reference fuel for future transportation and, in the USA in particular, a vision for its production from advanced nuclear reactors has been formulated. Fulfillment of this vision depend on its economics in 2020 or later. Prior to 2020, hydrogen needs to gain a substantial foothold without incurring excessive costs for the establishment of the distribution network for the new fuel. Water electrolysis and steam-methane reforming (SMR) are the existing hydrogen-production technologies, used for small-scale and large-scale production, respectively. Provided electricity is produced at costs expected for nuclear reactors of near-term design, electrolysis appears to offer superior economics when the SMR-related costs of distribution and sequestration (or an equivalent emission levy) are included. This is shown to hold at least until several percentage points of road transport have been converted to hydrogen. Electrolysis has large advantages over SMRs in being almost scale-independent and allowing local production. The key requirements for affordable electrolysis are low capital cost and relatively high utilization, although the paper shows that it should be advantageous to avoid the peaks of electricity demand and cost. The electricity source must enable high utilization as well as being itself low-cost and emissions-free. By using off-peak electricity, no extra costs for enhanced electricity distribution should occur. The longer-term supply of hydrogen may ultimately evolve away from low-temperature water electrolysis but it appears to be an excellent technology for early deployment and capable of supplying hydrogen at prices not dissimilar from today's costs for gasoline and diesel provided the vehicle's power unit is a fuel cell.

  3. Considering supply and demand of electric energy in life cycle assessments - a review of current methodologies

    International Nuclear Information System (INIS)

    Rehberger, M.; Hiete, M.

    2015-01-01

    A stable power grid requires a balance between electricity supply and demand. To compensate for changes in the demand the network operator puts on or takes off power plants from the net. Peak load plants operate only at times of high electricity demand. As levels for air pollutants emissions are typically lower for peak load plants for reasons of cost-effectiveness, one could argue that a unit of electric energy consumed during peak load has always been associated with a higher environmental impact than at other times. Furthermore, renewable energy technologies, smart approaches for improving the matching between electricity consumption and supply and new products such as electric vehicles or net zero emission buildings gain in importance. In life cycle assessment (LCA) environmental impacts associated with the production and possibly transmission of electricity are most often assessed based on temporally averaged national electricity mixes as electricity flows cannot be traced back to their origin. Neither fluctuations in the supply structure nor the composition of energy supply at a certain moment or regional differences are accounted for. A literature review of approaches for handling electricity in LCA is carried out to compare strengths and weaknesses of the approaches. A better understanding and knowledge about the source of electricity at a given time and place might be valuable information for further reducing environmental impacts, e.g. by shifting electricity consumption to times with ample supply of renewables. Integrating such information into LCA will allow a fairer assessment of a variety of new products which accept a lower energy efficiency to achieve a better integration of renewables into the grid.

    In Sub-Saharan Africa, policy changes have begun to pave the way for community distribution of injectable contraceptives but sustaining such efforts remains challenging. Combining social marketing with community-based distribution provides an opportunity to recover some program costs and compensate workers with proceeds from contraceptive sales. This paper proposes a model for increasing access to injectable contraceptives in rural settings by using community-based distributers as social marketing agents and incorporating financing systems to improve sustainability. This intervention was implemented in three districts of the Central Zone of Tigray, Ethiopia and program data has been collected from November 2011 through October 2012. A total of 137 Community Based Reproductive Health Agents (CBRHAs) were trained to provide injectable contraceptives and were provided with a loan of 25 injectable contraceptives from a drug revolving fund, created with project funds. The price of a single dose credited to a CBRHA was 3 birr ($0.17) and they provide injections to women for 5 birr ($0.29), determined with willingness-to-pay data. Social marketing was used to create awareness and generate demand. Both quantitative and qualitative methods were used to examine important feasibility aspects of the intervention. Forty-four percent of CBRHAs were providing family planning methods at the time of the training and 96% believed providing injectable contraceptives would improve their services. By October 2012, 137 CBRHAs had successfully completed training and provided 2541 injections. Of total injections, 47% were provided to new users of injectable contraceptives. Approximately 31% of injections were given for free to the poorest women, including adolescents. Insights gained from the first year of implementation of the model provide a framework for further expansion in Tigray, Ethiopia. Our experience highlights how program planners can tailor interventions to match family

    The study investigates the promotion of direct marketing and supply on demand of electric power from renewable energy sources in Germany. the study shows that renewable energy sources are a good option for facing the challenges of the future. However, the potential is often left unused because of a lack of incentives in the current pricing system. To solve this problem, the Federal Ministry of the Environment, Nature Conservation and Nuclear Safety authorized two studies that are to enable or improve the utilization of the integration potentials of the renewable energy sources. Two model proposals based on these studies are presented here. The model proposing a bonus for combined-cycle power plants is to ensure supply on demand of electric power from renewables with the aid of integrated power storage systems. However, it is found that this model will not generate significant effects for power supply on demand. The second model proposes financial incentives; it will work well for renewable power supply systems that can be controlled, e.g. bioenergy, run-of-river power plants with power storage, and biogas plants. On the other hand, supply-dependent technologies like wind power, photovoltaic power, run-of-river power plants without power storage, and geothermal power plants with very low variable cost, the goal is not fully reached. In contrast to the first model, the market incentives model will enhance the integration of renewable energy sources in the competitive market by largely eliminating market risks. (orig./RHM)

  6. DEVELOPMENT OF THE E-GOVERNMENT MARKET IN THE EUROPEAN UNION: AN ANALYSIS OF THE SUPPLY VERSUS DEMAND SIDES

    Full Text Available E-government represents one of the most palpable results of the dynamic development of the information and communication technology. Defined mostly as an intensive use of information technologies to provide public services, e-government has been approached in the literature rather from a technological perspective, with a significant importance given to the supply and a lower attention paid to the demand side. The increasing interest in taking into consideration the demand side in the development of the e-government initiatives and projects has created the foundation for a shift in the way the conceptual framework for e-government planning and implementation is defined, from the technology infrastructure and costs to the customer-centric character of all the efforts done. The European Union put e-government on its agenda aiming to improve access to the public information and services, increase transparency of public administration, exploit effectively the information technology within public administration, and establishing e-procurement. The development of the e-government services in the Member States, as it is expressed by the data regarding the supply and demand side, has been conducted in a more or less different manner that led, at the Unions level, to a relatively high availability but a rather low usage of the specific services. The paper explores the relationship between the e-government supply and demand based on the secondary data referring to the public services available to the citizens (as these are defined by the Eurostat methodology and the usage of these services by the individuals, integrating them through an analytical matrix inspired by the BCG model. Probably the most important conclusion of this analysis states that development of the e-government services has not been accompanied by measures meant to stimulate their usage in the most of the European Union Member States. The analytical matrix allowed also the identification

    The penetration of wind and solar generating resources is expected to dramatically increase in the United States over the coming years. It is widely understood that large scale deployment of these types of renewable energy sources (e.g., wind, solar) that have variable and less predictable production characteristics than traditional thermal resources poses integration challenges for bulk power system operators. At present, bulk power system operators primarily utilize strategies that rely on existing thermal generation resources and improved wind and solar energy production forecasts to manage this uncertainty; a host of additional options are also envisioned for the near future including demand response (DR). There are well-established bodies of research that examine variable generation integration issues as well as demand response potential; but, the existing literature that provides a comparative assessment of the two neither treats this topic comprehensively nor in a highly integrated fashion. Thus, this paper seeks to address these missing pieces by considering the full range of opportunities and challenges for mass market DR rates and programs to support integration of variable renewable generation. - Highlights: ► Mass market demand response can help manage the integration of renewable resources. ► To be more effective, retail electricity rates must apply contemporaneous prices. ► Demand response programs will require shorter duration and more frequent events. ► Mass market customers will likely need to accept control technology. ► Market rules and regulatory policies must change to expand demand response's role.

    The objective of this dissertation is to identify and discuss the main tools in implementing flexibility in supply and demand in the natural gas market, as well as highlight those which are the most appropriate for the Brazilian market. Flexibility, in this context, means the ability to guarantee a balance of supply versus demand without deficits, considering, mainly, the seasonal variations (winter-summer). From there, the study analyzes these flexibility tools in detail. Next, it discusses which of these flexibility tools are currently being used in more mature foreign markets and which tools could be feasibly applied to the Brazilian market. This dissertation also addresses how the natural gas thermoelectric market in Brazil shows a wide range of seasonality due to this segment's nature of complementing the Brazilian hydroelectric complex. This occurs because the capacity to generate hydroelectricity depends on rainfall for supplying reservoirs. Because of this interdependence, it examines how each the natural gas industry and the power industry operate, and their convergence. The flexibility tools which are already implemented here in Brazil are then presented. Finally, additional relevant new concepts and information are discussed to support the conclusions and final comments about the flexibility tools evolution and new applications. (author)

    To review research literature and available information on the extent and impacts of marketing, current policy response and the interests engaged in the policy debate in order to inform recommendations for policy change on alcohol marketing. Relevant literature, including systematic reviews and publicly available information (websites and participant observation) is reviewed and synthesized. Alcohol marketing has expanded markedly in the past 50 years and, while there remains uncertainty about the impact across the population, there is now clear evidence of its impact on the consumption of young people. Few countries have effective policy in place restricting alcohol marketing, and there is a lack of an international response to alcohol marketing which crosses national boundaries. The protection of alcohol marketing has been a major focus for vested interest groups and this has affected governmental response at national and international levels. There has been a lack of non-governmental organization engagement. The policy response to tobacco marketing provides a clear contrast to that of alcohol marketing policy and provides a model for alcohol marketing policy. The global exposure of young people to alcohol marketing requires an urgent policy response. The Framework Convention on Tobacco Control provides an appropriate model for global governance to control alcohol marketing. There are extant examples of national level legislation achieving comprehensive bans with France's Loi Evin providing a feasible model. Resources from philanthropic organizations to allow non-governmental organization engagement are urgently required, as is engagement by the governmental sector independent of commercial influence. © 2012 The Author, Addiction © 2012 Society for the Study of Addiction.

  14. Consequences of EU enlargement for supply and demand in the electricity market with special emphasis on nuclear power

    International Nuclear Information System (INIS)

    Jaeger, G.

    2004-01-01

    After the enlargement of the European Union, Europe has acquired a new dimension which is reflected also on the electricity market. The aggregate European electricity requirement of 3 000 TWh in Europe constitutes approximately one quarter of the world electricity generation. Nuclear power contributes a major share of 966 TWh. In electricity generation from nuclear power, EU-25 is No. 1 in the world. The rising demand for electricity cannot be met by the existing power plant park in the next few decades. Insufficient possibilities of exchange among countries and, especially, the enormous requirement to replace more than 200,000 MW of electricity generating capacity in Europe by 2020, plus another 100,000 MW arising from growing demand, make a comprehensive renewal of the European power plant park indispensable. After the EU enlargement, the standards of the ''old'' European Union are the yardstick for the entire ''new'' Union. This gives rise to enormous efforts, especially in the accession countries, to curb emissions and increase safety. The need for modern power plant technology is becoming particularly apparent in these cases. The example of the ten new member countries clearly shows the options realistically available for electricity generation in the future and indispensable for a favorable infrastructure. The conventional energy resources, i. e. coal, gas, and nuclear power, will be the main sources of electricity generation in Europe over the next few decades. This finding does not meet the expectations of many members of the public who feel that renewables would make the largest contribution to power supply in twenty years' time. This makes it imperative to regain popular acceptance in order to ensure electricity generation at favorable conditions and at a high level of environmental protection in the whole of Europe, with enough leeway to further advance the expansion of renewables and support a positive economic development of Europe.

  15. The making of a market. Supply- and demand-side perspectives on institutional innovation in Sweden's wood fuel use

    International Nuclear Information System (INIS)

    2001-01-01

    This thesis documents and analyses the rapidly increasing wood fuel use in Sweden in five separate studies of prominent actors in the making of the wood fuel market. These studies report government policy, forest owners' incentives, and district heating companies' experiences. The development of wood fuel use is examined as a story of technological and institutional change initially prompted by government policy. The change has involved dedicated action among all of the actors, with the Swedish government initiating new policies, legislation, and information activities, with district heating companies investing in new technology and trading, and with forest owners making new decisions on forest management practices. Institutional change in the wood fuel sector, in other words, is the result of innovation on the part of the actors involved. The papers included in the study identify and analyse concerns of the actors involved in making the wood fuel market. Within the district heating sector, transaction costs, as measured by problems to trade perceived by managements, have decreased with learning. Transformation costs, due to technical problems, are not perceived to have followed this trend. Technical investments in heat production have a long technical life time and demand large investment costs. This in turn means long planning and decision periods. Investments are made for a number of company-specific reasons, perhaps most importantly simply to increase heat and/or electricity generation capacity. Policy instruments may tip a decision in favor of wood fuels, but they could not be the single parameter determining company investments. Two kinds of forest owners selling wood fuels were identified, a forest manager type who acts more on his/her own initiative, and another kind, who relies more on the advice of the traditional timber buyer. Forest owners selling wood fuels contemplating whether to sell wood fuels or not are strongly influenced by soil fertility

  16. How to fit demand side management (DSM) into current Chinese electricity system reform?

    DSM is one of the best and most practical policy tools available to China for balancing environmental protection and economic growth. The new round of electricity system reform provides a good opportunity to consolidate and integrate DSM policy and expedite its development and implementation. DSM policy can be upgraded by incorporating it into the current electricity system reform. Comparing the potential acceleration of electricity price reform with the possibility of imposing a System Benefit Charge (SBC), the author argues that support for a SBC would be much easier to gather among policymakers and stakeholders in a short time and would have a much better policy effect in the current situation. The author discusses three kinds of price discrimination related to the DSM development in China: time-based electricity pricing, electricity price discrimination for industrial structure adjustment in China (Fujian Province as a case), and direct power purchases by large customers and preferential tariff policy. These can be well designed to be combined with DSM and energy efficiency policy. - Highlights: ► Elements of DSM have been in place since 1993, but without even and reinforced policy. ► DSM can be upgraded by fitting it into current Chinese electricity system reform. ► Both electricity price reform and SBC would mean increases in electricity payment. ►Imposing SBC is much easier and better than speeding up electricity price reform. ► Three kinds of price discrimination can be well designed to be combined with DSM.

    2005-01-01

    When examining the healthcare industry, the need for continuing education in internal functions (i.e., HR management) has been documented. However, equally important to success in the healthcare industry are external functions such as marketing. In an expansion of research on internally focused functions, we report findings from an exploratory study designed to examine the perceptions of executives about managerial skill needs in the externally focused area of marketing. Specifically, we examine eight key tasks in marketing and ask executives to rate the level of knowledge required for each and then to assess current, or actual, levels of knowledge in the field. Findings suggest that pricing strategy, product strategy, and segmentation and targeting were the tasks that require the most knowledge for healthcare marketers, and that they do, in fact, perceive various gaps in all of the areas examined. Implications and suggestions for future research are provided.

  1. Simulation of current pricing-tendencies in the German electricity market for private consumption

    International Nuclear Information System (INIS)

    Mueller, Moritz; Sensfuss, Frank; Wietschel, Martin

    2007-01-01

    The German electricity market for private consumption is characterized by increasing prices and low participation of the consumers. This prompts us to investigate the interdependencies between the customers' engagement in the market and the suppliers' pricing strategies. Based on an analysis of the German retail market, an agent-based simulation model is developed. Whereas the behaviour of private customers is calibrated on field data, the suppliers learn to maximize profits with a feedback-learning heuristic. The simulation results show a tendency of rising prices, which are created without the assumption of tacit collusion among suppliers. We conclude that in Germany the current market pressure of private customers may not be a sufficient incentive for suppliers to lower electricity prices. (author)

    Objectives To take inventory of the current state of affairs of Market Access Launch Excellence in the life sciences industry. To identify key gaps and challenges for Market Access (MA) and discuss how they can be addressed. To generate a baseline for benchmarking MA launch excellence. Methodology An online survey was conducted with pharmaceutical executives primarily working in MA, marketing, or general management. The survey aimed to evaluate MA excellence prerequisites across the product life cycle (rated by importance and level of implementation) and to describe MA activity models in the respective companies. Composite scores were calculated from respondents’ ratings and answers. Results Implementation levels of MA excellence prerequisites generally lagged behind their perceived importance. Item importance and the respective level of implementation correlated well, which can be interpreted as proof of the validity of the questionnaire. The following areas were shown to be particularly underimplemented: 1) early integration of MA and health economic considerations in research and development decision making, 2) developing true partnerships with payers, including the development of services ‘beyond the pill’, and 3) consideration of human resource and talent management. The concept of importance-adjusted implementation levels as a hybrid parameter was introduced and shown to be a viable tool for benchmarking purposes. More than 70% of respondents indicated that their companies will invest broadly in MA in terms of capital and headcount within the next 3 years. Conclusions MA (launch) excellence needs to be further developed in order to close implementation gaps across the entire product life cycle. As MA is a comparatively young pharmaceutical discipline in a complex and dynamic environment, this effort will require strategic focus and dedication.

    The article presents an overview of global demand and trade in hard coal (steam and coking). Coal demand has grown steadily over the past thirty years but coal trade has and will continue to grow at a faster rate. Transport contributes a relatively high proportion to the final price. Demand growth is strongest in countries with limited resources while production is declining in some countries with mature mining industries. There is a shift to demand in Asian markets. Spot contracts and tender transactions are replacing long-term contracts and e-commerce is developing. Prices are expected to remain stable, relative to those of oil and gas. China is expected to remain the world's second longest supplier of coal. 9 refs., 13 figs.

    2017-08-01

    Medical devices play a central role in the diagnosis and treatment of diseases but also bring the potential for adverse events, hazards or malfunction with serious consequences for patients and users. Medical device manufacturers are therefore required by law to monitor the performance of medical devices that have been approved by the competent authorities (post market surveillance). Conducting a nationwide online-survey in the German medical device sector in Q2/2014 in order to explore the current status of the use of post market instruments we obtained a total of 118 complete data sets, for a return rate of 36%. The survey included manufacturers of different sizes, producing medical devices of all risk classes. The post market instruments most frequently reported covered the fields of production monitoring and quality management as well as literature observation, regulatory vigilance systems, customer knowledge management and market observation while Post Market Clinical Follow-up and health services research were being used less for product monitoring. We found significant differences between the different risk classes of medical devices produced and the intensity of use of post market instruments. Differences between company size and the intensity of instruments used were hardly detected. Results may well contribute to the development of device monitoring which is a crucial element of the policy and regulatory system to identify device-related safety issues.

    The greatest challenge in integrating renewable energies into the German and European power supply system lies in levelling out the imbalances between the fluctuating supply of energy from the wind and sun on the one side and the steady demand of the consumers on the other. Aside from the expansion of supra-regional transmission systems and storage power plants one instrument that has raised great hopes is the possibility of adapting demand to supply. These methods are known by the names of demand response (DR) or demand side management (DSM) and are at the core of the ''smart grid'' concept.

    2011-04-01

    Social marketing uses marketing principles and techniques to induce a target audience to voluntary accept, reject, change or abandon a behaviour for the benefit of individuals, groups, or society as a whole. Thus, individual or societal gain is the primary goal of social marketing. This kind of marketing is frequently used in the United States or in Canada in several fields such as healthcare, social work, or the environment. In 2008, we introduced these strategies and techniques in the field of blood donation in France. This article describes what has been achieved in the last three years and outlines the main steps in the social marketing planning process: analyzing the social marketing environment, defining target audiences and objectives, building and implementing strategies and action plans, evaluating and monitoring. On the way to self-sufficiency, while respecting donors, social marketing is additional to the work done by the blood collection staffs, communication teams, and volunteers. Social marketing is a complementary tool to the work done by the blood collection staff, communication teams and blood donation organizations and can help to meet the challenge of self-sufficiency while still allowing for the privacy and rights of donors.

    Full Text Available Acute myeloid leukemia (AML is an aggressive, fast-growing cancer beginning inside bone marrow and spreading into the blood system, most often occurring in immature white blood cells. It has the lowest five-year survival rate among other types of leukemia and if left untreated, it can be fatal. Even though there have been significant improvements in the treatment of other related subtypes, AMLtargeted therapy development have been limited. The current market for AML drugs cannot fill the high unmet needs in terms of drug safety and efficacy, and the growing aging population presents increased opportunities for new drugs. Considering these driving forces, it is believed that promising opportunities exist for new entrants to capture value from underserved segments of the market. It is estimated that the market size for AML drugs in 2020 will reach US$1.67 billion with an average annual growth of nearly 23%. Therefore, it is highly recommended for pharmaceutical companies to invest in this area of drug development as soon as possible in order to maximize gains from their investments as novel therapeutics enter the AML market at a rapid pace.

    This handbook on biofuels provides a comprehensive overview of different types of biofuels, and the technical options that exist to market the biofuels volumes expected to be consumed in the EU Member States in 2020. The study concludes that by fully utilizing the current blending limits of biodiesel (FAME) in diesel (B7) and bioethanol in petrol (E10) up to 7.9% share of biofuels in the EU transport sector can be technically reached by 2020. Increasing use of advanced biofuels, particularly blending of fungible fuels into diesel (eg. HVO and BTL) and the use of higher ethanol blends in compatible vehicles (e.g. E20), can play an important role. Also, the increased use of biomethane (in particular bio-CNG) and higher blends of biodiesel (FAME) can contribute. However, it is essential for both governments and industry to decide within 1 or 2 years on the way ahead and take necessary actions covering both, the fuels and the vehicles, to ensure their effective and timely implementation. Even though a range of technical options exist, many of these require considerable time and effort to implement and reach their potential. Large scale implementation of the options beyond current blending limits requires new, targeted policy measures, in many cases complemented by new fuel and vehicle standards, adaptation of engines and fuel distribution, etc. Marketing policies for these vehicles, fuels and blends are also likely to become much more important than in the current situation. Each Member State may develop its own strategy tailored to its market and policy objectives, but the EU should play a crucial facilitating role in these developments.

    The natural gas industry is currently enjoying healthy growth prospects. Not only is the demand for natural gas steadily growing; the outlook for increasing gas reserves is promising as well. The success of natural gas in the marketplace reflects, on one hand, continuous attention paid to public and customer requirements and, on the other hand, the ability of the gas industry to direct technological developments toward the increasing public demand for gas at competitive market prices supplied in a reliable, safe and environmentally friendly manner. In the past, the gas industry has been involved in the development of technologies for everything from gas production to the end user and from borehole to burner tip, and the author believes that the industry must continue or even increase its emphasis on technology in the future in order to capture new market opportunities. He explains this by looking at the supply side, the demand side and the structural side of the business

    Analysis of the energy consumption in 2011 of major countries by Enerdata, based on our global energy database. The energy consumption growth in the G20 slowed down to 2% in 2011, after the strong increase of 2010. The economic crisis is largely responsible for this slow growth. For several years now, the world energy demand is characterized by the bullish Chinese and Indian markets, while developed countries struggle with stagnant economies, high oil prices, resulting in stable or decreasing energy consumption.

    A total of 105 countries have introduced IPV as of September 2016 of which 85 have procured the vaccine through UNICEF. The Global Eradication and Endgame Strategic Plan 2013-2018 called for the rapid introduction of at least one dose of IPV into routine immunization schedules in 126 all OPV-using countries by the end of 2015. At the time of initiating the procurement process, demand was estimated based on global modeling rather than individual country indications. In its capacity as procurement agency for the Global Polio Eradication Initiative and Gavi, the Vaccine Alliance, UNICEF set out to secure access to IPV supply for around 100 countries. Based on offers received, sufficient supply was awarded to two manufacturers to meet projected routine requirements. However, due to technical issues scaling up vaccine production and an unforecasted demand for IPV use in campaigns to interrupt wild polio virus and to control type 2 vaccine derived polio virus outbreaks, IPV supplies are severely constrained. Activities to stretch supplies and to suppress demand have been ongoing since 2014, including delaying IPV introduction in countries where risks of type 2 reintroduction are lower, implementing the multi-dose vial policy, and encouraging the use of fractional dose delivered intradermally. Despite these efforts, there is still insufficient IPV supply to meet demand. The impact of the supply situation on IPV introduction timelines in countries are the focus of this article, and based on lessons learned with the IPV introductions, it is recommended for future health programs with accelerated scale up of programs, to take a cautious approach on supply commitments, putting in place clear allocation criteria in case of shortages or delays and establishing a communication strategy vis a vis beneficiaries. © The Author 2017.

    Recent increases in basic food prices are severely affecting vulnerable populations worldwide. Proposed causes such as shortages of grain due to adverse weather, increasing meat consumption in China and India, conversion of corn to ethanol in the United States, and investor speculation on commodity markets lead to widely differing implications for policy. A lack of clarity about which factors are responsible reinforces policy inaction. Here, for the first time to our knowledge, we construct a dynamic model that quantitatively agrees with food prices. The results show that the dominant causes of price increases are investor speculation and ethanol conversion. Models that just treat supply and demand are not consistent with the actual price dynamics. The two sharp peaks in 2007/2008 and 2010/2011 are specifically due to investor speculation, whereas an underlying upward trend is due to increasing demand from ethanol conversion. The model includes investor trend following as well as shifting between commodities, equities, and bonds to take advantage of increased expected returns. Claims that speculators cannot influence grain prices are shown to be invalid by direct analysis of price-setting practices of granaries. Both causes of price increase, speculative investment and ethanol conversion, are promoted by recent regulatory changes-deregulation of the commodity markets, and policies promoting the conversion of corn to ethanol. Rapid action is needed to reduce the impacts of the price increases on global hunger.

    Bio-based plastics are used as raw materials in a wide range of applications and provide potential for mitigating climate change by lowering CO2 emissions. However, because of the high production costs compared to fossil-based alternative products, they are currently not cost competitive on the market. Moreover, the decrease of oil price as main antecedent of fossil-based plastics has even been diminishing their competiveness. Thus, the future of bio-based plastics on the market depends on th...

    2008-03-13

    Norwegian cancer patients frequently use Noni. The objective of this study was to find out whether the way noni is marketed in Norway and the health claims made about the product harmonize with current scientific knowledge of its benefits/adverse effects. An overview of medical research on noni was obtained from three databases. Web sites for private persons and for companies that sell noni in Norway were examined. Books, pamphlets etc. from a company specializing in selling information material about noni, were also examined. 48 scientific articles were included in the study, but none of these were clinical studies of humans. Several pharmacological effects of noni have been shown in vitro and in animal models (e.g., increased survival for animals with cancer). Information material describes noni as a health-promoting product that patients with most diseases will benefit from. Noni is to a great extent sold by multi-level marketing, but is also commonly sold by health food stores. There is no scientific basis for claiming that patients will benefit from using noni for any diseases. The way this product is sold has several worrying aspects.

    It is critical to have pediatric post-marketing safety systems that contain enough clinical and epidemiological detail to draw regulatory, public health, and clinical conclusions. The pediatric safety surveillance workshop (PSSW), coordinated by the Food and Drug Administration (FDA), identified these pediatric systems as of 2010. This manuscript aims to update the information from the PSSW and look critically at the systems currently in use. We reviewed North American pediatric post-marketing safety systems such as databases, networks, and research consortiums found in peer-reviewed journals and other online sources. We detail clinical examples from three systems that FDA used to assess pediatric medical product safety. Of the 59 systems reviewed for pediatric content, only nine were pediatric-focused and met the inclusion criteria. Brief descriptions are provided for these nine. The strengths and weaknesses of three systems (two of the nine pediatric-focused and one including both children and adults) are illustrated with clinical examples. Systems reviewed in this manuscript have strengths such as clinical detail, a large enough sample size to capture rare adverse events, and/or a patient denominator internal to the database. Few systems include all of these attributes. Pediatric drug safety would be better informed by utilizing multiple systems to take advantage of their individual characteristics.

    Full Text Available In the context of globalization and due to the accelerated progress made in information and communication technology, more and more companies offer their employees the option of telecommuting. For the past twenty years, telecommuting has been on an asceding trend, an incresing number of people embracing the ability to work from home, using a computer and internet connection to communicate for their jobs. The goal of the paper is to explain the overall notion of telecommuting and to analyze the current trends in the United States and European Union markets. Another objective is to assess the advantages and disadvantages of telecommuting and the important role played by this concept within the striving purpose of corporations to achieve their strategic targets. The study is based upon specialized literature reviews regarding the emergence of telecommuting and the role it plays in organizations. A comparative analysis was conducted by the authors on two regional markets, United States and the European Union, in order to assess the trend in telecommuting and the factors that influence it. The outcome of the research shows that although the benefits of telecommuting are numerous, it does not come without challenges, both being applicable for both the employer, as well as for the employee. The research results of this study can be used by organizations when considering to offer their employees flexible work opportunities which can positively influence the long term business performance.

    Since the amendment of the EEG in January 2012, enormous amounts of electric power from renewable energy sources are marketed directly, i.e. outside the control of power supply grid owners and operators that formerly sold the electric power in the stock exchange. Inaccurate prognoses made by the direct marketers as well as their marketing strategies have increased the demand for balancing power and made critical situations in the power grid even more difficult.

    Decarbonising transport is proving to be one of today's major challenges for the global automotive industry due to many factors such as the increase in greenhouse gas and particulate emissions affecting not only the climate but also humans, the increase in pollution, rapid oil depletion, issues with energy security and dependency from foreign sources and population growth. For more than a century, our society has been dependent upon oil, and major breakthroughs in low- and ultra-low carbon technologies and vehicles are urgently required. This review paper highlights the current status of hybrid, battery and fuel cell electric vehicles from an electrochemical and market point of view. The review paper also discusses the advantages and disadvantages of using each technology in the automotive industry and the impact of these technologies on consumers.

  5. Housing demand or money supply? A new Keynesian dynamic stochastic general equilibrium model on China's housing market fluctuations

    There is a bitter controversy over what drives the housing price in China in the existing literature. In this paper, we investigate the underlying driving force behind housing price fluctuations in China, especially focusing on the role of housing demand shock with that of money supply shock in explaining housing price movements, by a new Keynesian dynamic stochastic general equilibrium model. Empirical results suggest that it is housing demand, instead of money supply, that mainly drives China's housing price movements. Relevant policy implication is further discussed, namely, whether to consider the housing price fluctuations in the conduct of monetary policy. By means of the policy simulations, we find that a real house price-augmented money supply rule is a better monetary policy for China's economy stabilization. 1. Investment refers to fixed capital investment. 2. Housing price refers to national average housing price. Quarterly data on housing price during the period of our work are not directly available. However, monthly data of the value of sales on housing and sale volume on housing can be directly obtained from National Bureau of Statistics of China. We add up the monthly data and calculate one quarter's housing price by dividing the value of housing sales by its sale volume in one quarter. 3. M2 means the broad money supply in China.

    This lecture investigates the effects of the societal framework on operators of biogas plants in the further development of biogas and its contribution to the German Energiewende. Influences are not only from politics and economy but stakeholders also shape the development to come. A visible part of the existing plants have quickly to be transformed to a demand driven supply. If not, it is most likely that biogas will disappear from the stage within some 15 years - except for waste treatment. In a future of growing wind and solar energy supply we will experience a.. of shortage and surplus within a day, and through the.seasons. Prices will fluctuate increasingly. Controllable energy generators will run for a decreasing number of hours daily. Biogas should contribute to one or two high-price periods a day, when it is dark, low wind, or high demand, but at a higher capacity than today. This pattern, in combination with a valuable use of its thermal energy production, can furthermore offer an economic feasible prospect for biogas plants after their period of subsidized EEG feed-in tariff By now, only few biogas plants are designed accordingly. Most of them produce their power continuously. Only if biogas plants will change towards peak load operation, its unique combination of renewable and controllable energy supply will be recognized, and biogas can contribute a valuable share to a sustainable energy system. Stakeholders can and should support this change.

    There is not enough marketing of dentistry; but there certainly is too much selling of poor quality service that is being passed off as dentistry. The marketing concept makes the patient and the patients' needs the ultimate criteria of marketing efforts. Myths and good practices for effective marketing that will promote oral health are described under the traditional four "Ps" categories of "product" (best dental care), "place" (availability), "promotion" (advertising and other forms of making patients aware of available services and how to use them), and "price" (the total cost to patients of receiving care).

    This article presents a dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major players along the gas chain are depicted including: producers, consumers, storage and pipeline operators, as well as intermediate local traders. Our economic structure description takes into account market power and the demand representation tries to capture the possible fuel substitution that can be made between the consumption of oil, coal, and natural gas in the overall fossil energy consumption. We also take into account long-term contracts in an endogenous way, which makes the model a Generalized Nash Equilibrium problem. We discuss some means to solve such problems. Our model has been applied to represent the European natural gas market and forecast, until 2030, after a calibration process, consumption, prices, production, and natural gas dependence. A comparison between our model, a more standard one that does not take into account energy substitution, and the European Commission natural gas forecasts is carried out to analyze our results. Finally, in order to illustrate the possible use of fuel substitution, we studied the evolution of the natural gas price as compared to the coal and oil prices. (authors)

    Polynomials and Spline regression are the numeric model where they used to obtain the performance of methods, distance relationship models for cement retailers in Banda Aceh, predicts the market area for retailers and the economic order quantity (EOQ). These numeric models have their difference accuracy for measuring the mean square error (MSE). The distance relationships between retailers are to identify the density of retailers in the town. The dataset is collected from the sales of cement retailer with a global positioning system (GPS). The sales dataset is plotted of its characteristic to obtain the goodness of fitted quadratic, cubic, and fourth polynomial methods. On the real sales dataset, polynomials are used the behavior relationship x-abscissa and y-ordinate to obtain the models. This research obtains some advantages such as; the four models from the methods are useful for predicting the market area for the retailer in the competitiveness, the comparison of the performance of the methods, the distance of the relationship between retailers, and at last the inventory policy based on economic order quantity. The results, the high-density retail relationship areas indicate that the growing population with the construction project. The spline is better than quadratic, cubic, and four polynomials in predicting the points indicating of small MSE. The inventory policy usages the periodic review policy type.

    Full Text Available Althougt at first sight the crisis appears as a disturbance of the regular course of economic, social and organizational, this is a necessary step that turns old structures and relations to some superior functional. Under these conditions, hawever, it is absolutely necessary that the situation be properly evaluated by an analysis of developments and labour market structures and be taken right decision for the purposes of proper management of existing and potential recovery so far underused resources: people, values and strategies. The impact of the economic crisis on labour markets displays significant variation from one country to another. Employment rates and unemployment rates will be compared between European countries and for different groups of workers. Some countries have succeeded in keeping employment levels up and unemployment levels down through recourse to employmentpreservation and employment-creation measures combined with an expansion of active labour market policies. Moreover, certain labour market groups or categories have been particularly hard hit by the crisis. These include men, temporary workers, youth and migrant workers. In the EU Member States, crossing the crisis period was marked by changes in the sense orientation flexibleworking time and conservation work, a strategy that ensures rapid and reversible adaptation to the needs ofproduction entities present.

  12. LPG world supply and demand

    Holmes, Ch.

    2008-01-01

    Over the course of this decade, the global LPG market has moved from being tight, where supply barely exceeded non-price sensitive demand, to the current market situation where supply growth has outstripped demand growth to such an extent that current fundamentals suggest that considerable length will prevail in the market over the near term. As is the case for many other energy commodity markets, the LPG industry has experienced a considerable transformation over the last five years with many new LPG supply projects coming on-stream and demand growth in many developing markets slowing in response to higher energy prices. The near term challenge for LPG producers will be securing outlets for output as the market becomes increasingly oversupplied. With expanding LPG supply and a worldwide tightness in the naphtha market, it is expected that petrochemical consumers will favor relatively low priced LPG over naphtha and the resulting increase in LPG cracking rates will go some way to reducing the expected supply surplus. However, the timing of several new LPG supply projects and the start-up of LPG-based petrochemical plants in the Middle-East are expected to impact global LPG trade and pricing over the next few years. Thus, at this point in time, the global LPG market has a high degree of uncertainty with questions remaining over the impact of high energy (and LPG) prices on traditional and developing market demand, the timing of new supply projects and the combined effect of these two factors on international LPG prices. World LPG production has been rising in nearly every region of the world over the last few years and totaled about 229 million tons in 2007, which is some 30 million tons per year higher than in 2000. The exception is North America which accounts for the largest share of global LPG supply at about 24% but production there has remained relatively flat in recent years. Strong LPG production growth in the Middle-East which contributed to about 19% of

    This report serves as discussion document for the workshop 'Technologies for fuel cells and hydrogen in road transport' in Paris, France, March 2009. The workshop is part of the Efonet (Energy Foresight Network, www.efonet.org ) program initiated by the European Commission. As a starting point, the status quo of fuel cell technology is analyzed from an innovation perspective, compared with the current vehicle deployment in demonstration projects worldwide. Then, cost reductions of fuel cell and drive train components that can be achieved as function over time are modelled in a learning curve approach. This provides a forecast on the expected vehicle cost by cumulative production, enabling discussion on the connection between necessary vehicle deployment and current demonstration projects, also in respect to project finance. Within the EU HyWays project, four scenarios have been developed to model the penetration rates for hydrogen vehicles in transport. All scenarios are determined by two influencing factors, policy support and level of technological learning. Depending on the scenario, it is assumed that mass production of vehicles starts either by 2013 (2016) with a group of 5 (4) first movers that achieve up to 90% plant utilization in different time frames. Given the bandwidth of scenario results, it is possible to redefine cost targets and provide recommendations for the necessary policy support. The report also provides an assessment of current hydrogen vehicle RD and D activities by different OEMs and gives an indication on the expected market entry strategies and time frame. To conclude, cost of conventional and hydrogen vehicles are compared on a euro/km level, testing several policy measures for their suitability to lower the expected high vehicle cost for the end-consumer.

  16. Consequences of the Budget Deficit in the Current Crisis in Romania. Implications on the Labor Market

    influence on the mechanisms that generate economic stability and economic development effort. For example, on the short-term, the budget deficit reduces the national saving, leads to decreased supply of market funds, which increases the interest rates. In this context, the volume of investment decreases, the consumption is reduced, affecting the volume of economic activities and employment. The psychological influences combined with the economic boost caused by budget deficits act directly on financial markets, leading to falling down the values of capital markets and the depreciation of the currencies sometimes sudden for the national currency. Even if the depreciation of the exchange rate is often a method used to equilibrate the commercial balance, an uncontrolled amplification of budgetary deficits can sometimes lead to monetary depreciation. These, over a certain level, can neutralize the benefits obtained in the external plan by strong worsening of the internal imbalances, mainly through the increased inflationary pressures in the economy. So, in current circumstances, when you want to identify and encourage those branches and sub-branches of national economy which can be developed in the global economy, one of the basic decisions regarding the interpretation of economic processes is the adoption of a dynamic and creative concept which considers both requirements to use the fiscal levers in economic development policy and the possibility of modifying the structure of budgetary revenues and expenses.

  17. An Agent-Based Optimization Framework for Engineered Complex Adaptive Systems with Application to Demand Response in Electricity Markets

    Haghnevis, Moeed

    The main objective of this research is to develop an integrated method to study emergent behavior and consequences of evolution and adaptation in engineered complex adaptive systems (ECASs). A multi-layer conceptual framework and modeling approach including behavioral and structural aspects is provided to describe the structure of a class of engineered complex systems and predict their future adaptive patterns. The approach allows the examination of complexity in the structure and the behavior of components as a result of their connections and in relation to their environment. This research describes and uses the major differences of natural complex adaptive systems (CASs) with artificial/engineered CASs to build a framework and platform for ECAS. While this framework focuses on the critical factors of an engineered system, it also enables one to synthetically employ engineering and mathematical models to analyze and measure complexity in such systems. In this way concepts of complex systems science are adapted to management science and system of systems engineering. In particular an integrated consumer-based optimization and agent-based modeling (ABM) platform is presented that enables managers to predict and partially control patterns of behaviors in ECASs. Demonstrated on the U.S. electricity markets, ABM is integrated with normative and subjective decision behavior recommended by the U.S. Department of Energy (DOE) and Federal Energy Regulatory Commission (FERC). The approach integrates social networks, social science, complexity theory, and diffusion theory. Furthermore, it has unique and significant contribution in exploring and representing concrete managerial insights for ECASs and offering new optimized actions and modeling paradigms in agent-based simulation.

  18. MARKET TOURS, PEDDLER RECEIPTS AND THE SHOPKEEPER GRAPE VINE: AN IMPORT WHOLESALER’S ATTEMPTS TO GAUGE RURAL, AFRICAN CONSUMER DEMAND IN EARLY COLONIAL NORTHWESTERN TANZANIA

    Directory of Open Access Journals (Sweden)

    Laird Jones

    1999-01-01

    Full Text Available This paper examines how early colonial, town-based wholesalers discerned rural African consumer tastes and measured demand for imported goods by focusing on the experience of the O’Swald Mwanza branch from 1906 through 1916. Like many metropolitan firms, O’Swald had extensive experience in the earlier caravan trade. Thus, several decades later, its representatives arrived in Mwanza expecting that import sales would still conform to the tastes of elite caravan era consumers. With the extension of steam transport into the interior and the onset of an early colonial “Cash Crop Revolution,” however, many more rural cultivators and herdspeople than ever before had the means to acquire imports, and these new consumers proved far more fickle with regard to brand, style and novelty than firms like O’Swald had anticipated. They no longer accepted some caravan era favorites, and desired others in increasing variety. Thus, in order to stay on top of what the firm only slowly came to understand as an emerging mass market, the O’Swald men spied on their competition, engaged in brand name advertising, interrogated shopkeepers and peddlers, and increasingly market-tested new products.

    This study intended to estimate the spatial and temporal variation of current and projected water demand and water availability under climate change scenarios in Weyib River basin, Bale mountainous area of Southeastern Ethiopia. Future downscaled climate variables from three Earth System Models under the three RCP emission scenarios were inputted into ArcSWAT hydrological model to simulate different components of water resources of a basin whereas current and projected human and livestock population of the basin is considered to estimate the total annual water demand for various purposes. Results revealed that the current total annual water demand of the basin is found to be about 289 Mm3, and this has to increase by 83.47% after 15 years, 200.67% after 45 years, and 328.78% after 75 years by the 2020s, 2050s, and 2080s, respectively, from base period water demand mainly due to very rapid increasing population (40.81, 130.80, and 229.12% by the 2020s, 2050s, and 2080s, respectively) and climatic variability. The future average annual total water availability in the basin is observed to be increased by ranging from 15.04 to 21.61, 20.08 to 23.34, and 16.21 to 39.53% by the 2020s, 2050s, and 2080s time slice, respectively, from base period available water resources (2333.39 Mm3). The current water availability per capita per year of the basin is about 3112.23 m3 and tends to decline ranging from 11.78 to 17.49, 46.02 to 47.45, and 57.18 to 64.34% by the 2020s, 2050s, and 2080s, respectively, from base period per capita per year water availability. This indicated that there might be possibility to fall the basin under water stress condition in the long term.

  20. Optimal Fare, Vacancy Rate, and Subsidies under Log-Linear Demand with the Consideration of Externalities for a Cruising Taxi Market

    2017-01-01

    Full Text Available Externality is an important issue for formulating the regulation policy of a taxi market. However, this issue is rarely taken into account in the current policy-making process, and it has not been adequately explored in prior research. This study extends the model proposed by Chang and Chu in 2009 with the aim of exploring the effect of externality on the optimization of the regulation policy of a cruising taxi market. A closed-form solution for optimizing the fare, vacancy rate, and subsidy of the market is derived. The results show that when the externality of taxi trips is taken into consideration, the optimal vacancy rate should be lower and the subsidy should be higher than they are under current conditions where externality is not considered. The results of the sensitivity analysis on the occupied and vacant distance indicate that the relation of the vacant distance to the marginal external cost is more sensitive than the occupied distance. The result of the sensitivity analysis on the subsidy shows the existence of a negative relationship between the marginal external cost and the optimal subsidy.

    Full Text Available In an increasingly globalized world, where the effects of technology have an overwhelming impact on people's lives, meaning an increase in appetite for consumption of luxury goods, of lifestyle, it seems that conventional resources are becoming fewer and their use in industrial processes lead to environmental harm, at least from pollution. Essentially, oil prices influence governments, companies, and markets of raw materials markets of finite economic goods, markets of conventional and unconventional energy and an assumed oil crisis would lead to stronger inflections on the market, with repercussions on the overall level of prices, the oil price being generally regarded as decisive for the other prices in the economy.

    The dawning of this millennium broke new ground in life science and technology, presented us genomic and proteomic revolution, nanotechnology innovation, and high performance liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) used for separating and identifying new chemical entities at pico-, or even femto-concentrations. Applications of these high technologies to the traditional Chinese medicine (TCM) opened a new chapter in the ancient medicine, and prompted us to re-evaluate the thousand-year-old phytomedicine–ginseng from current perspectives. We, therefore, collected the latest information (mostly within 10 years) on ginseng, and condensed the information into two parts of this review serial. The present part covers etymology of ginseng, its pharmacognosy (natural origin, physical appearance, chemical properties, and specie identification), its cultivation and processing-related metabolic changes in active ingredients, standardized analytical methods used for quality control of various ginseng products, modern analytical methods used to identify and classify more than 100 chemical entities (many were recently unfolded) derived from ginseng species and their metabolites. The global markets and production of ginseng and relevant government regulations are herein updated to exchange information and understandings about current people’s uses and cultivation of ginseng. The second part of the review serial will classify all these 100 chemical entities separated from various ginseng species into different groups based on their structural similarities, and summarize bioactivities of these entities. The second part of the review serial will also focus on recent findings of ginseng pharmacology and its clinical trials for various diseases, and brief side effects of ginseng. PMID:19601793

    2018-03-24

    The purpose of the study is to characterize current practice patterns of abdominal radiologists based on work descriptions within job postings on numerous national radiology specialty websites. Job postings for either "abdominal" or "body" radiologists were searched weekly on five society websites (SAR, SCBT-MR, ARRS, ACR, RSNA) over a 1-year period. Postings were reviewed for various characteristics. Nine hundred and sixteen total ads for 341 unique abdominal radiologist positions were reviewed (34.6% academic, 64.2% private practice, 1.2% other). Postings occurred most commonly in March (12.3%) and least commonly in November (4.8%). States with most positions were Florida (27), California (26), and New York (24). Of postings delineating expectations of specific abdominal modalities, 67.4% mentioned MRI, 58.5% ultrasound, 41.1% fluoroscopy, 14.3% PET, and 54.0% interventions. Additional non-abdominal expectations included general radiology (28.7%), breast imaging (21.1%), and general nuclear medicine (9.7%). Additional skills included prostate MRI (7.0%), OBGYN ultrasound (5.0%), and CT colonoscopy (2.6%). 79.2% required an abdominal imaging fellowship (specifically a body MRI fellowship in 4.1%). By using job postings for abdominal radiologists, we have taken a practical approach to characterizing the current status of this subspecialty, reflecting recent job expectations and requirements. The large majority of positions required a body fellowship, and the positions commonly entailed a variety of skills beyond non-invasive diagnostic abdominal imaging. Of note, expectations of considerable minorities of positions included abdominal interventions, general radiology, and breast imaging. These insights may guide the development of abdominal radiology fellowships and mini-fellowships, as well as assist radiologists entering or returning to the job market.

    New risks in nosocomial infections and the dramatic increase in antibiotic-resistant pathogens in healthcare facilities have pointed to the urgent need for a good education of students and practitioners in the basics of hospital hygiene and infection prevention. On the other hand in the last 10 years a large number of institutes of hygiene in universities were closed with remarkable consequences concerning the decreased education in modern hygiene and public health. A broad historical overview over the last 200 years of teaching hygiene and public health at German universities is given which was integrated into the education of medical students. Nowadays many universities do not teach modern hygiene and public health. The demand of re-establishing new institutes of hygiene by the German Medical Council is discussed. The curriculum for the formation of hospital hygienists is presented.

    Full Text Available The current state of the insurance market of Ukraine in the post-crisis period, by comparison with the pre-crisis was investigated in the paper. The insurance market in the pre-crisis period grew rapidly, but was unable to withstand the economic crisis and suffered a crushing blow. The economic crisis of 2008-2009 led to a decrease of the demand for financial services in general and insurance services in particular. The lack of development of the insurance market created high barriers for responding and adapting to changes that occurred during the crisis.

    2001-06-01

    Full Text Available This paper investigates the effect of the exchange market interventions of the Bank of Korea on the exchange rate of Korean won vis-a-vis US dollar during the 1997 currency crisis. In particular, this paper tests the effects of spot and forward market interventions, using daily intervention data of the Bank of Korea. During the 1997 period, Korea faced two series of crisis in January-March and September-November. It turns out that the spot market intervention was effective in stabilizing the spot market exchange rate at least during the first crisis period. In contrast, there seemed no effect of the forward market intervention. Forward market intervention was rather destabilizing through forward exchange rate during the second crisis period. This implies that even though the forward and sterilized spot market interventions are equivalent in their effect on exchange rate, these two instruments can widely diverge from each other under the circumstances of exchange rate volatility and speculation.

    Full Text Available Pakistan is currently facing physical and economic water scarcity issues that are further complicated by the rapid increase in its population and by climate change. Many studies have focused on the physical water scarcity using hydrological modeling and the measurement of the impact of climate change on water resources in the Upper Indus Basin (UIB. However, few studies have concentrated on the importance of the economic water scarcity, that is, the water management issue under the looming impacts of climate change and the population explosion of Pakistan. The purpose of this study is to develop a management strategy which helps to achieve water security and sustainability in the Upper Indus Basin (UIB with the help of different socio-economic and climate change scenarios using WEAP (Water Evaluation and Planning modeling. The streamflow data of five sub-basins (Gilgit, Hunza, Shigar, Shyok, and Astore and the entire Upper Indus Basin (UIB were calibrated (2006–2010 and validated (2011–2014 in the WEAP model. The coefficient of determination and Nash Sutcliffe values for the calibration period ranged from 0.81–0.96. The coefficient of determination and the Nash Sutcliffe values for the validation period ranged from 0.85–0.94. After the development of the WEAP model, the analysis of the unmet water demand and percent coverage of the water demand for the period of 2006–2050 was computed. Different scenarios were generated for external driving factors (population growth, urbanization, and living standards and the impact of climate change to evaluate their effect on the current water supply system. The results indicated that the future unmet water demand is likely to reach 134 million cubic meters (mcm by the year 2050 and that the external driving factors are putting more pressure on the supply service. This study further explores the importance of proposed dams (likely to be built until 2025 by WAPDA (Water and Power Development

    Scanlon, Dennis P; Chernew, Michael; Swaminathan, Shailender; Lee, Woolton

    2006-12-01

    Health care reform proposals often rely on increased competition in health insurance markets to drive improved performance in health care costs, access, and quality. We examine a range of data issues related to the measures of health insurance competition used in empirical studies published from 1994-2004. The literature relies exclusively on market structure and penetration variables to measure competition. While these measures are correlated, the degree of correlation is modest, suggesting that choice of measure could influence empirical results. Moreover, certain measurement issues such as the lack of data on PPO enrollment, the treatment of small firms, and omitted market characteristics also could affect the conclusions in empirical studies. Importantly, other types of measures related to competition (e.g., the availability of information on price and outcomes, degree of entry barriers, etc.) are important from both a theoretical and policy perspective, but their impact on market outcomes has not been widely studied.

    Full Text Available Market crises are interpreted in much the same way. Hence action is also always of a similar type, regardless of the market crisis that may have occurred. It is a similar set of tools that are applied to all crises, and usually this has to do with managing the money supply, interest rates, and slapping on austerity measures. But this is a myopic view. Crises are never the same. Presented here is a holistic model that draws inspiration form the journey a seed makes in becoming a flower in more fully understanding the nature of the crisis we may be facing. Action will be different depending on what phase in the journey the economy is assessed at being. In this paper we look at market crises scanning four decades, from the Bear Market of the early 1970s to recent European Union Sovereign Debt Crises.
