  4. Locational Prices in Capacity Subscription Market Considering Transmission Limitations

    Directory of Open Access Journals (Sweden)

    S. Babaeinejad Sarookolaee

    2013-06-01

    Full Text Available This study focuses on one of the most effective type of capacity markets named Capacity Subscription (CS market which is predicted to be widely used in the upcoming smart grids. Despite variant researches done about the mechanism and structure of capacity markets, their performances have been rarely tested in the presence of network constraints. Considering this deficiency, we tried to propose a new method to determine capacity prices in the network considering the transmission line flow limitations named Local capacity Prices (LP. This method is quite new and has not been tried before in any other similar researches. The philosophy of the proposed method is to determine capacity prices considering each consumer share of total peak demand. The first advantage of LP is that the consumers who benefit from the transmission facilities and are the responsible for transmission congestions, pay higher capacity prices than those whom their needed electricity is prepared locally. The second advantage of LP is that consumers connected to the same bus do not have to pay same capacity price due to their different shares of total peak demand. For more clarification, two other different methods named Branches Flow limit as a Global Limit (BFGL and Locational Capacity Prices (LCP are proposed and compared to the LP method in order to show LP method efficiency. The numerical results obtained from case studies show that the LP method follows more justice market procedure which results in more efficient capacity prices in comparison to BFGL and LCP methods.

  10. Cigarette price level and variation in five Southeast Asian countries.

    Science.gov (United States)

    Liber, Alex C; Ross, Hana; Ratanachena, Sophapan; Dorotheo, E Ulysses; Foong, Kin

    2015-06-01

    To monitor and analyse impacts of the interaction between tobacco excise tax policy and industry price strategy, on the price level and variation of cigarettes sold in five Southeast Asian countries (Indonesia, Cambodia, Lao PDR, the Philippines and Vietnam). Prices of cigarette sold by sticks and packs were collected through an in-person survey of retailers during 2011. Mean cigarette prices and price variation were calculated in each study country for single cigarettes, whole packs and brand groups. Price variation of whole packs was greater in countries with ad-valorem excise tax structures (Cambodia, Lao PDR and Vietnam) than in countries with multitiered specific excise taxes (Indonesia and the Philippines). The price variation for single sticks appeared to be driven by local currency denomination. Cigarettes sold individually cost more per stick than cigarettes sold in whole packs in every brand group except for Indonesia's domestic brands. Tobacco industry strategy and excise tax structure drove the price level and variation of cigarettes sold in packs, while currency denominations influence the selling price of single sticks. To maximise the effectiveness of tobacco tax policies, countries should adopt specific excise tax structures to decrease cigarette price variation, which would minimise opportunities for smokers to 'trade down' to a cheaper brand to avoid a tax-driven price increase.

    Freed, Gary L; Cowan, Anne E; Gregory, Sashi; Clark, Sarah J

    2009-12-01

    The purpose of this work was to collect data regarding vaccine prices and reimbursements in private practices. Amid reports of physicians losing money on vaccines, there are limited supporting data to show how much private practices are paying for vaccines and how much they are being reimbursed by third-party payers. We conducted a cross-sectional survey of a convenience sample of private practices in 5 states (California, Georgia, Michigan, New York, and Texas) that purchase vaccines for administration to privately insured children/adolescents. Main outcome measures included prices paid to purchase vaccines recommended for children and adolescents and reimbursement from the 3 most common, non-Medicaid payers for vaccine purchase and administration. Detailed price and reimbursement data were provided by 76 practices. There was a considerable difference between the maximum and minimum prices paid by practices, ranging from $4 to more than $30 for specific vaccines. There was also significant variation in insurance reimbursement for vaccine purchase, with maximum and minimum reimbursements for a single vaccine differing from $8 to more than $80. Mean net yield per dose (reimbursement for vaccine purchase minus price paid per dose) varied across vaccines from a low of approximately $3 to more than $24. Reimbursement for the first dose of vaccine administered ranged from $0 to more than $26, with a mean of $16.62. There is a wide range of prices paid by practices for the same vaccine product and in the reimbursement for vaccines and administration fees by payers. This variation highlights the need for individual practices to understand their own costs and reimbursements and to seek opportunities to reduce costs and increase reimbursements.

  16. Power Subscription Strategy

    1998-12-21

    This document lays out the Bonneville Power Administration`s Power Subscription Strategy, a process that will enable the people of the Pacific Northwest to share the benefits of the Federal Columbia river Power System after 2001 while retaining those benefits within the region for future generations. The strategy also addresses how those who receive the benefits of the region`s low-cost federal power should share a corresponding measure of the risks. This strategy seeks to implement the subscription concept created by the Comprehensive Review in 1996 through contracts for the sale of power and the distribution of federal power benefits in the deregulated wholesale electricity market. The success of the subscription process is fundamental to BPA`s overall business purpose to provide public benefits to the Northwest through commercially successful businesses.

    This study examines lowest cigarette prices in all tobacco retail outlets in Washington D.C. (n=750) in relation to the type and number of high schools nearby, controlling for confounders. The lowest overall and Newport menthol prices were significantly lower at outlets near public non-charter and charter schools compared with outlets near private schools. Given higher smoking prevalence and more price-sensitive youth subgroups in U.S. public schools, exposure to low prices may contribute to tobacco-related health disparities in minority and low-income populations. Tobacco taxes combined with policies to minimize the increasing use of price as a marketing tool are critical. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2010-01-01

    The aim of this study was to assess the seasonal price of sugar cane, fuel alcohol (hydrated and anhydrous) and electricity tariffs as a way of aiding tool for optimization of energy generation, using biomass originating from cane sugar. Using the method of moving average centered was concluded that cane and electricity rates were close to seasonal average, with low range of prices, suggesting the non-occurrence of seasonal variation in prices. Unlike the seasonal indices of ethanol showed seasonal variation of prices with greater amplitude of seasonal index. Thus, the results suggest that the utilization of by-products of sugar cane to produce electrical power points to the prospect of reducing risks associated with variations in the price of ethanol, thereby contributing to greater stability and possibility to those involved in planning alcohol sector.

  3. Crude oil price analysis and forecasting based on variational mode decomposition and independent component analysis

    Science.gov (United States)

    E, Jianwei; Bao, Yanling; Ye, Jimin

    2017-10-01

    As one of the most vital energy resources in the world, crude oil plays a significant role in international economic market. The fluctuation of crude oil price has attracted academic and commercial attention. There exist many methods in forecasting the trend of crude oil price. However, traditional models failed in predicting accurately. Based on this, a hybrid method will be proposed in this paper, which combines variational mode decomposition (VMD), independent component analysis (ICA) and autoregressive integrated moving average (ARIMA), called VMD-ICA-ARIMA. The purpose of this study is to analyze the influence factors of crude oil price and predict the future crude oil price. Major steps can be concluded as follows: Firstly, applying the VMD model on the original signal (crude oil price), the modes function can be decomposed adaptively. Secondly, independent components are separated by the ICA, and how the independent components affect the crude oil price is analyzed. Finally, forecasting the price of crude oil price by the ARIMA model, the forecasting trend demonstrates that crude oil price declines periodically. Comparing with benchmark ARIMA and EEMD-ICA-ARIMA, VMD-ICA-ARIMA can forecast the crude oil price more accurately.

    2017-08-24

    Accessibility to essential cancer medications in low- and middle-income countries is threatened by insufficient availability and affordability. The objective of this study is to characterize variation in transactional prices for essential cancer medications across geographies, medication type, and time. Drug purchase prices for 19 national and international buyers (representing 29 total countries) between 2010 and 2014 were obtained from Management Sciences for Health. Median values for drug pricing were computed, to address outliers in the data. For comparing purchase prices across geographic units, medications, and over time; Mann-Whitney U tests were used to compare two groups, Kruskal Wallis H tests were used to compare more than two groups, and linear regression was used to compare across continuous independent variables. During the five-year data period examined, the median price paid for a package of essential cancer medication was $12.63. No significant differences in prices were found based on country-level wealth, country-level disease burden, drug formulation, or year when medication was purchased. Statistical tests found significant differences in prices paid across countries, regions, individual medications, and medication categories. Specifically, countries in the Africa region appeared to pay more for a package of essential cancer medication than countries in the Latin America region, and cancer medications tended to be more expensive than anti-infective medications and cardiovascular medications. Though preliminary, our study found evidence of variation in prices paid by health systems to acquire essential cancer medications. Primarily, variations in pricing based on geographic location and cancer medication type (including when comparing to essential medicines that treat cardiovascular and infectious diseases) indicate that these factors may impact availability, affordability and access to essential cancer drugs. These factors should be taken into

  8. Probabilistic electricity price forecasting with variational heteroscedastic Gaussian process and active learning

    International Nuclear Information System (INIS)

    Kou, Peng; Liang, Deliang; Gao, Lin; Lou, Jianyong

    2015-01-01

    Highlights: • A novel active learning model for the probabilistic electricity price forecasting. • Heteroscedastic Gaussian process that captures the local volatility of the electricity price. • Variational Bayesian learning that avoids over-fitting. • Active learning algorithm that reduces the computational efforts. - Abstract: Electricity price forecasting is essential for the market participants in their decision making. Nevertheless, the accuracy of such forecasting cannot be guaranteed due to the high variability of the price data. For this reason, in many cases, rather than merely point forecasting results, market participants are more interested in the probabilistic price forecasting results, i.e., the prediction intervals of the electricity price. Focusing on this issue, this paper proposes a new model for the probabilistic electricity price forecasting. This model is based on the active learning technique and the variational heteroscedastic Gaussian process (VHGP). It provides the heteroscedastic Gaussian prediction intervals, which effectively quantify the heteroscedastic uncertainties associated with the price data. Because the high computational effort of VHGP hinders its application to the large-scale electricity price forecasting tasks, we design an active learning algorithm to select a most informative training subset from the whole available training set. By constructing the forecasting model on this smaller subset, the computational efforts can be significantly reduced. In this way, the practical applicability of the proposed model is enhanced. The forecasting performance and the computational time of the proposed model are evaluated using the real-world electricity price data, which is obtained from the ANEM, PJM, and New England ISO

    United States. Bonneville Power Administration

    1998-12-01

    The Bonneville Power Administration (BPA) has decided to adopt a Power Subscription Strategy for entering into new power sales contracts with its Pacific Northwest customers. The Strategy equitably distributes the electric power generated by the Federal Columbia River Power System (FCRPS) within the framework of existing law. The Power Subscription Strategy addresses the availability of power; describes power products; lays out strategies for pricing, including risk management; and discusses contract elements. In proceeding with this Subscription Strategy, BPA is guided by and committed to the Fish and Wildlife funding Principles for the BPA announced by the Vice President of the US in September 1998. This Record of Decision (ROD) addresses the issues raised by commenters who responded to BPA`s Power Subscription Strategy Proposal during and after the comment period that began with the release of the Proposal on September 18, 1998. The ROD is organized in approximately the same way as the Proposal and the Power Subscription Strategy that BPA developed based on the comments received. Abbreviations of party names used in citations appear in the section just preceding this introduction; a list of all the commenters follows the text of the ROD.

  10. New pricing approaches for bundled payments: Leveraging clinical standards and regional variations to target avoidable utilization.

    Develop pricing models for bundled payments that draw inputs from clinician-defined best practice standards and benchmarks set from regional variations in utilization. Health care utilization and claims data for a cohort of incident Ontario ischemic and hemorrhagic stroke episodes. Episodes of care are created by linking incident stroke hospitalizations with subsequent health service utilization across multiple datasets. Costs are estimated for episodes of care and constituent service components using setting-specific case mix methodologies and provincial fee schedules. Costs are estimated for five areas of potentially avoidable utilization, derived from best practice standards set by an expert panel of stroke clinicians. Alternative approaches for setting normative prices for stroke episodes are developed using measures of potentially avoidable utilization and benchmarks established by the best performing regions. There are wide regional variations in the utilization of different health services within episodes of stroke care. Reconciling the best practice standards with regional utilization identifies significant amounts of potentially avoidable utilization. Normative pricing models for stroke episodes result in increasingly aggressive redistributions of funding. Bundled payment pilots to date have been based on the costs of historical service patterns, which effectively 'bake in' unwarranted and inefficient variations in utilization. This study demonstrates the feasibility of novel clinically informed episode pricing approaches that leverage these variations to target reductions in potentially avoidable utilization.

    Hybrid journals contains articles behind a pay-wall to be subscribed, as well as papers made open access when author pays article processing charge (APC). In such cases, an Institution will end up paying twice and Publishers tend to double-dip. Discussions and pilot models are emerging on pricing options, such as “offset pricing,” [where APCs are adjusted or discounted with subscription costs as vouchers or reductions in next year subscriptions, APCs beyond the subscription costs are modestly capped etc] and thus reduce Institutions’ cost. This presentation will explain different models available and how can we attain a transparent costing structure, where the scholarly community can feel the fairness in Publishers’ pricing mechanisms. Though most of the offset systems are developed through national level or consortium level negotiations, experience of individual institutions, like KAUST that subscribe to large e-journals collections, is important in making right decisions on saving Institutes costs and support openness in scholarly communications.

  14. Time variation in European carbon pass-through rates in electricity futures prices

    International Nuclear Information System (INIS)

    Huisman, Ronald; Kiliç, Mehtap

    2015-01-01

    The European Union Emissions Trading Scheme is a means to price emission allowances. Electricity market prices should reflect these market prices of emission allowances as they are a cost factor for power producers. The pass-through rate is the fraction of the emission allowance price that is passed through to electricity market prices. It is often measured and presented as an average or a fixed estimate over some time period. However, we expect that the pass-through rates should actually vary over time as electricity supply curves reflect the marginal costs of different producers that differ in emission intensity. We apply a Kalman Filter approach to observe pass-through rates in Germany and U.K. and find strong support for time varying instead of fixed pass-through rates. Although policy makers are interested in the impact of a policy on average, our results indicate that one needs to be careful with the time-frame over which pass-through rates are measured for policy evaluation, as an incorrect chosen evaluation period could cause an under- or overestimation of the pass-through rate. In addition, our model helps to provide policy makers with insight in the development of pass-through rates when market circumstances change with respect to power production. - Highlights: • We analyse the time-variation of the emission pass-through rate in power prices. • We examine historical futures prices for Germany and the U.K. • We test the hypothesis by using the Kalman Filter methodology. • Strong support is found that pass-through rates vary over time. • The chosen time-frame for pass-through rates is important for policy evaluation.

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

    The UK dairy sector has undergone considerable structural change in recent years, with a decrease in the number of producers accompanied by an increased average herd size and increased concentrate use and milk yields. One of the key drivers to producers remaining in the industry is the profitability of their herds. The current paper adopts a holistic approach to decomposing the variation in dairy profitability through an analysis of net margin data explained by physical input-output measures, milk price variation, labour utilization and managerial behaviours and characteristics. Data are drawn from the Farm Business Survey (FBS) for England in 2007/08 for 228 dairy enterprises. Average yields are 7100 litres/cow/yr, from a herd size of 110 cows that use 0·56 forage ha/cow/yr and 43·2 labour h/cow/yr. An average milk price of 22·57 pence per litre (ppl) produced milk output of £1602/cow/yr, which after accounting for calf sales, herd replacements and quota leasing costs, gave an average dairy output of £1516/cow/yr. After total costs of £1464/cow/yr this left an economic return of £52/cow/yr (0·73 ppl) net margin profit. There is wide variation in performance, with the most profitable (as measured by net margin per cow) quartile of producers achieving 2000 litres/cow/yr more than the least profitable quartile, returning a net margin of £335/cow/yr compared to a loss of £361/cow/yr for the least profitable. The most profitable producers operate larger, higher yielding herds and achieve a greater milk price for their output. In addition, a significantly greater number of the most profitable producers undertake financial benchmarking within their businesses and operate specialist dairy farms. When examining the full data set, the most profitable enterprises included significantly greater numbers of organic producers. The most profitable tend to have a greater reliance on independent technical advice, but this finding is not statistically significant

    We describe an event-based, publish-and-subscribe mechanism based on using 'smart subscriptions' to recognize weakly-structured events. We present a hierarchy of subscription languages (propositional, predicate, temporal and agent) and algorithms for efficiently recognizing event matches. This mechanism has been applied to the management of distributed applications.

    The United States has the highest drug costs in the world. Consumers complain about large price differences at pharmacies on generic drugs. To evaluate variation in cash prices of generic medications most prescribed in dermatology across different drugstores and states in United States. The 11 generic drugs most prescribed by dermatologists according to National Ambulatory Medical Care Survey were assessed. By using Google, the most common used pharmacies in United States were listed, which are located at a random selection of six states. By calling the first available number of each pharmacy in the six states and asking about the generic cash price of the smallest stock size and the most prescribed type, the data were collected. Drug prices varied; the median cumulative price of the 11 medications was highest at Rite Aid ($1226) and lowest at Walmart ($795.34) with 35% difference. The prices at CVS differed by 20% across different states; however, the prices at Walmart, Rite Aid and Walgreens were consistent. New York has the highest and Iowa the lowest prices, especially at CVS, ($1160.79) versus ($931.32). There are varieties in the prices for the generic medications in different pharmacies and States.

    In the future, district heating companies in Sweden must adapt to energy efficiency measures in buildings and variable fuel and electricity prices. Swedish district heating demands are expected to decrease by 1–2% per year and electricity price variations seem to be more unpredictable in the future. A cost-optimisation model of a Swedish local district heating system is constructed using the optimisation modelling tool MODEST. A scenario for heat demand changes due to increased energy efficiency in buildings, combined with the addition of new buildings, is studied along with a sensitivity analysis for electricity price variations. Despite fears that heat demand reductions will decrease co-generation of clean electricity and cause increased global emissions, the results show that anticipated heat demand changes do not increase the studied system's primary energy use or global CO 2 emissions. The results further indicate that the heat production plants and the fuels used within the system have crucial importance for the environmental impact of district heat use. Results also show that low seasonal variations in electricity price levels with relatively low winter prices promote the use of electric heat pumps. High winter prices on the other hand promote co-generation of heat and electricity in CHP plants. -- Highlights: ► A MODEST optimisation model of the Uppsala district heating system is built. ► The impact of heat demand change on heat and electricity production is examined. ► An electricity price level sensitivity analysis for district heating is performed. ► Heat demand changes do not increase the primary energy use or global CO 2 emissions. ► Low winter prices promote use of electric heat pumps for district heating production.

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

    Full Text Available Purpose: With the rapid progress of Internet of Things technology, the information service of IoT has got unprecedented development, and plays an increasingly important role in real life. For the increasing demand of information service, the pricing of information service becomes more important. This paper aims to analyze the strategic options and payoff function between information provider and intermediaries based on Stackelberg game. Firstly, we describe information service delivery method based on the Internet of Things specific function. Secondly, we calculate the consumer demand for the information service. Finally, we explain two kinds of strategic options by the game theory, and then discuss the optimal pricing method of information services based on profit maximization.Design/methodology/approach: To achieve this objective, Considering the consumer perceived value of Internet of Things Service changing, we establish a Stackelberg model in which the supplier is the leader followed by the middleman. Then, we compare the advantages of using individual pricing with that of bundling pricing.Findings: The results show that whether information providers adopt bundling pricing strategy or individual pricing strategy depends on the cost of perception equipment, if information providers want to adopt individual pricing strategy, the variation of consumers’ perception value of information services must meet certain conditions.Research limitations/implications: the providers make price for the information service, in addition to continuously improve the quality of information service, it also devotes resources to tapping and understanding market information, such as the sensor device price, the variation of perception value of information services and so on, so as to create competitive advantage. This paper is just a preliminary model, it does not take into account the effect of mixed bundling.Originality/value: In this research, a new model for

    THIS ARTICLE DEVELOPS A FORMAL MODEL FOR COMPARING THE COST STRUCTURE OF THE TWO MAIN TRANSPORT OPTIONS FOR NATURAL GAS: liquefied natural gas (LNG) and pipelines. In particular, it evaluates how variations in the prices of natural gas and greenhouse gas emissions affect the relative cost-efficiency of these two options. Natural gas is often promoted as the most environmentally friendly of all fossil fuels, and LNG as a modern and efficient way of transporting it. Some research has been carried out into the local environmental impact of LNG facilities, but almost none into aspects related to climate change. This paper concludes that at current price levels for natural gas and CO 2 emissions the distance from field to consumer and the volume of natural gas transported are the main determinants of transport costs. The pricing of natural gas and greenhouse emissions influence the relative cost-efficiency of LNG and pipeline transport, but only to a limited degree at current price levels. Because more energy is required for the LNG process (especially for fuelling the liquefaction process) than for pipelines at distances below 9100 km, LNG is more exposed to variability in the price of natural gas and greenhouse gas emissions up to this distance. If the prices of natural gas and/or greenhouse gas emission rise dramatically in the future, this will affect the choice between pipelines and LNG. Such a price increase will be favourable for pipelines relative to LNG.

    Full Text Available This study develops a new return model with respect to accounting fundamentals. The new return model is based on Chen and Zhang (2007. This study takes into account theinvestment scalability information. Specifically, this study splitsthe scale of firm’s operations into short-run and long-runinvestment scalabilities. We document that five accounting fun-damentals explain the variation of annual stock return. Thefactors, comprised book value, earnings yield, short-run andlong-run investment scalabilities, and growth opportunities, co associate positively with stock price. The remaining factor,which is the pure interest rate, is negatively related to annualstock return. This study finds that inducing short-run and long-run investment scalabilities into the model could improve the degree of association. In other words, they have value rel-evance.

    Retail marketing surveillance research highlights concerns about lower priced cigarettes in neighborhoods with a higher proportion of racial/ethnic minorities but focuses almost exclusively on premium brands. To remedy this gap in the literature, the current study examines neighborhood variation in prices for the cheapest cigarettes and a popular brand of cigarillos in a large statewide sample of licensed tobacco retailers in a low-tax state. All 61 local health departments in California trained data collectors to conduct observations in a census of eligible licensed tobacco retailers in randomly selected zip codes (n = 7393 stores, completion rate=91%). Data were collected in 2013, when California had a low and stagnant tobacco tax. Two prices were requested: the cheapest cigarette pack regardless of brand and a single, flavored Swisher Sweets cigarillo. Multilevel models (stores clustered in tracts) examined prices (before sales tax) as a function of neighborhood race/ethnicity and proportion of school-age youth (aged 5-17). Models adjusted for store type and median household income. Approximately 84% of stores sold cigarettes for less than $5 and a Swisher Sweets cigarillo was available for less than $1 in 74% of stores that sold the brand. The cheapest cigarettes cost even less in neighborhoods with a higher proportion of school-age residents and Asian/Pacific Islanders. Neighborhood disparities in the price of the cheapest combustible tobacco products are a public health threat. Policy changes that make all tobacco products, especially combustible products, less available and more costly may reduce disparities in their use and protect public health. Much of what is known about neighborhood variation in the price of combustible tobacco products focuses on premium brand cigarettes. The current study extends this literature in two ways, by studying prices for the cheapest cigarette pack regardless of brand and a popular brand of flavored cigarillos and by

    To (1) assess trends and variation in the market share of product types and potency sold in a legal cannabis retail market and (2) estimate how potency and purchase quantity influence price variation for cannabis flower. Secondary analysis of publicly available data from Washington State's cannabis traceability system spanning 7 July 2014 to 30 September 2016. Descriptive statistics and linear regressions assessed variation and trends in cannabis product variety and potency. Hedonic regressions estimated how purchase quantity and potency influence cannabis flower price variation. Washington State, USA. (1) A total of 44 482 176 million cannabis purchases, including (2) 31 052 123 cannabis flower purchases after trimming price and quantity outliers. Primary outcome measures were (1) monthly expenditures on cannabis, total delta-9-tetrahydrocannabinol (THC) concentration and cannabidiol (CBD) concentration by product type and (2) excise tax-inclusive price per gram of cannabis flower. Key covariates for the hedonic price regressions included quantity purchased, THC and CBD. Traditional cannabis flowers still account for the majority of spending (66.6%), but the market share of extracts for inhalation increased by 145.8% between October 2014 and September 2016, now comprising 21.2% of sales. The average THC-level for cannabis extracts is more than triple that for cannabis flowers (68.7% compared to 20.6%). For flower products, there is a statistically significant relationship between price per gram and both THC [coefficient = 0.012; 95% confidence interval (CI) = 0.011-0.013] and CBD (coefficient = 0.017; CI = 0.015-0.019). The estimated discount elasticity is -0.06 (CI = -0.07 to -0.05). In the state of Washington, USA, the legal cannabis market is currently dominated by high-THC cannabis flower, and features growing expenditures on extracts. For cannabis flower, both THC and CBD are associated with higher per-gram prices, and there are small but

  16. A cross-sectional analysis of variation in charges and prices across California for percutaneous coronary intervention.

    Directory of Open Access Journals (Sweden)

    Renee Y Hsia

    Full Text Available Though past studies have shown wide variation in aggregate hospital price indices and specific procedures, few have documented or explained such variation for distinct and common episodes of care.We sought to examine the variability in charges for percutaneous coronary intervention (PCI with a drug-eluting stent and without major complications (MS-DRG-247, and determine whether hospital and market characteristics influenced these charges.We conducted a cross-sectional analysis of adults admitted to California hospitals in 2011 for MS-DRG-247 using patient discharge data from the California Office of Statewide Health Planning and Development. We used a two-part linear regression model to first estimate hospital-specific charges adjusted for patient characteristics, and then examine whether the between-hospital variation in those estimated charges was explained by hospital and market characteristics.Adjusted charges for the average California patient admitted for uncomplicated PCI ranged from $22,047 to $165,386 (median: $88,350 depending on which hospital the patient visited. Hospitals in areas with the highest cost of living, those in rural areas, and those with more Medicare patients had higher charges, while government-owned hospitals charged less. Overall, our model explained 43% of the variation in adjusted charges. Estimated discounted prices paid by private insurers ranged from $3,421 to $80,903 (median: $28,571.Charges and estimated discounted prices vary widely between hospitals for the average California patient undergoing PCI without major complications, a common and relatively homogeneous episode of care. Though observable hospital characteristics account for some of this variation, the majority remains unexplained.

    The aim of this study was to assess the seasonal price of sugar cane, fuel alcohol (hydrated and anhydrous) and electricity tariffs as a way of aiding tool for optimization of energy generation, using biomass originating from cane sugar. Using the method of moving average centered was concluded that cane and electricity rates were close to seasonal average, with low range of prices, suggesting the non-occurrence of seasonal variation in prices. Unlike the seasonal indices of ethanol showed seasonal variation of prices with greater amplitude of seasonal index. Thus, the results suggest that the utilization of by-products of sugar cane to produce electrical power points to the prospect of reducing risks associated with variations in the price of ethanol, thereby contributing to greater stability and possibility to those involved in planning alcohol sector.

    We present the design, security proof, and implementation of an anonymous subscription service. Users register for the service by providing some form of identity, which might or might not be linked to a real-world identity such as a credit card, a web login, or a public key. A user logs on to the system by presenting a credential derived from information received at registration. Each credential allows only a single login in any authentication window, or epoch . Logins are anonymous in the sense that the service cannot distinguish which user is logging in any better than random guessing. This implies unlinkability of a user across different logins. We find that a central tension in an anonymous subscription service is the service provider's desire for a long epoch (to reduce server-side computation) versus users' desire for a short epoch (so they can repeatedly "re-anonymize" their sessions). We balance this tension by having short epochs, but adding an efficient operation for clients who do not need unlinkability to cheaply re-authenticate themselves for the next time period. We measure performance of a research prototype of our protocol that allows an independent service to offer anonymous access to existing services. We implement a music service, an Android-based subway-pass application, and a web proxy, and show that adding anonymity adds minimal client latency and only requires 33 KB of server memory per active user.

  10. Role of library's subscription licenses in promoting open access to scientific research

    KAUST Repository

    Buck, Stephen

    2018-04-30

    This presentation, based on KAUST’’s experience to date, will attempt to explain the different ways of bringing Open Access models to scientific Publisher’s licenses. Our dual approach with offset pricing is to redirect subscription money to publishing money and embed green open access deposition terms in understandable language in our license agreements. Resolving the inherent complexities in open access publishing, repository depositions and offsetting models will save libraries money and also time wasted on tedious and unnecessary administration work. Researchers will also save their time with overall clarity and transparency.

  11. Role of library's subscription licenses in promoting open access to scientific research

    KAUST Repository

    Buck, Stephen

    2018-01-01

    This presentation, based on KAUST’’s experience to date, will attempt to explain the different ways of bringing Open Access models to scientific Publisher’s licenses. Our dual approach with offset pricing is to redirect subscription money to publishing money and embed green open access deposition terms in understandable language in our license agreements. Resolving the inherent complexities in open access publishing, repository depositions and offsetting models will save libraries money and also time wasted on tedious and unnecessary administration work. Researchers will also save their time with overall clarity and transparency. This will enable trust and, where mistakes are made, and there inevitably will be with untried models, we can learn from these mistakes and make better, more robust services with auto deposition of our articles to our repository fed by Publishers’ themselves. The plan is to cover all Publishers with OA license terms for KAUST author’s right while continuing our subscription to them. There are marketing campaigns, awareness sessions are planned, in addition to establishing Libguides to help researchers, in addition to manage offset pricing models.

  15. Freemium Pricing

    DEFF Research Database (Denmark)

    Runge, Julian; Wagner, Stefan; Claussen, Jörg

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

    In this work, we use residual values obtained from an estimated hedonic pricing model to assess the role of district-level neighbourhood effects for the spatial variation in quality-adjusted rental prices in Berlin between 2008 and 2013. By doing so, we also aim at identifying hot and cold spots ...... analysis (ESDA) toolbox, we finally pinpoint particular hot spots of the city’s residential property market associated with a significant spatial clustering of similar rental price values around individual observations....... proximity to the city centre compared to similar properties in Berlin’s periphery once we control for the properties’ physical characteristics. The observed temporal evolution of the rental price distribution between 2008 and 2013 thereby hints at an ongoing gentrification process in Germany’s capital...... associated with the current housing market boom. This visual impression is also confirmed by the application of quantile regressions for a correlation analysis between quality-adjusted rental price values and Berlin district-level characteristics obtained from the last census in 2011.

  17. Capacity subscription and its market design impact

    International Nuclear Information System (INIS)

    Doorman, Gerard; Solem, Gerd

    2005-04-01

    Capacity Subscription (CS) implies that consumers buy (subscribe to) a certain amount of capacity. Their demand is limited to this capacity when the total power system is short of capacity and the System Operator activates controllable Load Limiting Devices (LLDs). The objective is to maintain system security by avoiding involuntary load shedding. The report describes a market design with CS. As a case study, an analysis is made of the changes in the market design of the Nordic system that would be necessary to implement CS. First the present Nordic market design is described. Focus is on the various market participants, their roles within various time horizons and their interactions. So it is described how CS works, why it works and what is necessary to make it work. Subsequently the necessary changes in the Nordic market structure are described. The major changes are the installation of the LLDs, the establishment of the necessary infrastructure to control the LLDs and the rules governing their control and the establishment of a capacity market. The major rule is that the System Operator announces LLD activation when a shortage situation is expected. In the capacity market generators offer available capacity during system peak conditions, while consumers bid their need for capacity. Market participants are the same as on the spot market, while small consumers buy through retailer. Generators are obliged to offer the capacity sold on the capacity market on the spot market during LLD activation. Failure to do so results in a penalty payment. The report further discusses issues like the need for verification procedures, import and export, generation pooling, the handling of small consumers, reserves and a possible implementation path of CS. With respect to transmission constraints it is argued that market splitting can be a viable option. It is concluded that CS can be a possible solution to maintain generation adequacy, but there are some serious challenges. The

  18. Food advertising on children's popular subscription television channels in Australia.

    Science.gov (United States)

    Hebden, Lana; King, Lesley; Chau, Josephine; Kelly, Bridget

    2011-04-01

    Trends on Australian free-to-air television show children continue to be exposed to a disproportionate amount of unhealthy food advertising. This study describes the nature and extent of food marketing on the Australian subscription television channels most popular with children. Advertisements broadcast on the six subscription television channels most popular with children were recorded over four days in February 2009. Advertised foods were coded as core/healthy, non-core/unhealthy or miscellaneous/other, and for persuasive marketing techniques (promotional characters, premium offers and nutrition claims). The majority of foods advertised were non-core (72%), with a mean rate of 0.7 non-core food advertisements broadcast per hour, per channel. The frequency of non-core food advertisements differed significantly across channels. Persuasive techniques were used to advertise non-core foods less frequently than core and miscellaneous foods. Non-core foods make up the majority of foods advertised on children's popular subscription channels. However, Australian children currently view less non-core food advertising on subscription television compared with free-to-air. Unlike free-to-air television, subscription services have the unique opportunity to limit inappropriate food marketing to children, given they are less reliant on advertising revenue. © 2011 The Authors.

  19. The minimum price required by investors in IPOs

    Directory of Open Access Journals (Sweden)

    Ahmed Jeribi

    2015-01-01

    Full Text Available With regard to purchasing Tunisian IPOs shares, the current paper aims at considering two types of investors: a non-institutional investor and an institutional one. Each is concerned with placing a purchase order at the offer price during the subscription period. In line with the literature on IPOs, we attempted to determine the minimum price required by an investor allowing for recovering the initial investment, information costs, transaction costs, and the offsetting of shortfall. We expect that the initial return of an IPO share in the Tunisian market is positively related to the following factors: the number of non-institutional investors participating during the subscription period, the subscription ratio of institutional investors, the expected rate of return by investors, the gap between the closing date of the subscription period and the day following the announcement of the subscription result, the gap between the announcement of the subscription result and the first listing day, the number of trading days, the cost of information and the transaction costs. However, it is negatively related to other determinants, such as the discount level, the number of shares allocated for a non-institutional investor and the number of offered shares, which are allocated to non-institutional investors.

    This paper examines how socio-economic status (SES) modifies how smokers adjust to changes in the price of tobacco products through utilization of multiple price minimizing techniques. Data come from the International Tobacco Control Policy Evaluation (ITC) Four Country Survey, nationally representative samples of adult smokers and includes respondents from Canada, the United States, the United Kingdom and Australia. Cross-sectional analyses were completed among 8,243 respondents (7,038 current smokers) from the survey wave conducted between October 2006 and February 2007. Analyses examined predictors of purchasing from low/untaxed sources, using discount cigarettes or roll-your-own (RYO) tobacco, purchasing cigarettes in cartons, and engaging in high levels of price and tax avoidance at last purchase. All analyses tested for interactions with SES and were weighted to account for changing and under-represented demographics. Relatively high levels of price and tax avoidance behaviors were present; 8% reported buying from low or untaxed source; 36% used discount or generic brands, 13.5% used RYO tobacco, 29% reported purchasing cartons, and 63% reported using at least one of these high price avoidance behaviors. Respondents categorized as having low SES were approximately 26% less likely to report using low or untaxed sources and 43% less likely to purchase tobacco by the carton. However, respondents with low SES were 85% more likely to report using discount brands/RYO compared to participants with higher SES. Overall, lower SES smokers were 25% more likely to engage in at least one or more tax avoidance behaviors compared to their higher SES counterparts. Price and tax avoidance behaviors are relatively common among smokers of all SES strata, but strategies differed with higher SES groups more likely to report traveling to a low-tax location to avoid paying higher prices, purchase duty free tobacco, and purchase by cartons instead of packs all of which were less

  9. Open access versus subscription journals: a comparison of scientific impact.

    Science.gov (United States)

    Björk, Bo-Christer; Solomon, David

    2012-07-17

    In the past few years there has been an ongoing debate as to whether the proliferation of open access (OA) publishing would damage the peer review system and put the quality of scientific journal publishing at risk. Our aim was to inform this debate by comparing the scientific impact of OA journals with subscription journals, controlling for journal age, the country of the publisher, discipline and (for OA publishers) their business model. The 2-year impact factors (the average number of citations to the articles in a journal) were used as a proxy for scientific impact. The Directory of Open Access Journals (DOAJ) was used to identify OA journals as well as their business model. Journal age and discipline were obtained from the Ulrich's periodicals directory. Comparisons were performed on the journal level as well as on the article level where the results were weighted by the number of articles published in a journal. A total of 610 OA journals were compared with 7,609 subscription journals using Web of Science citation data while an overlapping set of 1,327 OA journals were compared with 11,124 subscription journals using Scopus data. Overall, average citation rates, both unweighted and weighted for the number of articles per journal, were about 30% higher for subscription journals. However, after controlling for discipline (medicine and health versus other), age of the journal (three time periods) and the location of the publisher (four largest publishing countries versus other countries) the differences largely disappeared in most subcategories except for journals that had been launched prior to 1996. OA journals that fund publishing with article processing charges (APCs) are on average cited more than other OA journals. In medicine and health, OA journals founded in the last 10 years are receiving about as many citations as subscription journals launched during the same period. Our results indicate that OA journals indexed in Web of Science and/or Scopus are

  20. CERN Library - Reduction of subscriptions to scientific journals

    CERN Multimedia

    2005-01-01

    The Library Working Group for Acquisitions has identified some scientific journal subscriptions as candidates for cancellation. Although the 2005 budget is unchanged with respect to 2004 thanks to the efforts of the Management, it does not take account of inflation, which for many years has been much higher for scientific literature than the normal cost-of-living index. For 2006, the inflation rate is estimated to be 7-8%. Moreover, the Library does not only intend to compensate for the loss of purchasing power but also to make available some funds to promote new Open Access publishing models. (See Bulletin No.15/2005) The list of candidates can be found on the Library homepage (http://library.cern.ch/). In addition, some subscriptions will be converted to online-only, i.e. CERN will no longer order the print version of certain journals. We invite users to carefully check the list (http://library.cern.ch/). Comments on this proposal should be sent to the WGA Chairman, Rudiger Voss, with a copy to the Hea...

    2017-11-01

    Full Text Available In October 2015 Stockholm University Library (SUB decided to no longer use the services of a subscription agent for managing individual journal subscriptions. Instead, SUB has taken a do-it-yourself (DIY approach to subscriptions management and now renews and orders new journals directly from each publisher. In the light of two years of experience, this article discusses the key findings of this new way of working with subscriptions, the differences between the first and second year of renewing directly with publishers and the pros and cons of not using an agent. The article ends with a few recommendations and things for other libraries to consider before making the decision to do without a subscription agent and explains why SUB has decided to continue with the DIY approach.

  7. The relationship between innovation and price variation process innovations and product; La Relacion entre innovacion y variacion de los precios innovaciones de proceso y de producto

    Energy Technology Data Exchange (ETDEWEB)

    Gonzalez, X.; Miles-Touya, D.; Pazo, C.

    2012-07-01

    The aim of this study is to analyze the relationship between innovation and price changes, distinguishing between process and product innovations. The former directly affects production costs, the changes of which could be transferred to prices. The latter enables companies to differentiate their products vertically or horizontally and increases the consumers willingness to pay, which may lead companies to raise prices. The results show that firms that introduce product innovations are more likely to raise prices and firms that introduce process innovations are more likely to reduce them. The magnitudes of the effects are different. (Author)

    Reference price research suggest that consumers memorize and recall price information when selecting brands for frequently purchased products. In this study, we show that previous price-knowledge surveys provided imperfect estimates of reference price. Further, we propose to use a combination of price recall, price recognition, and deal recognition to measure representations to memorize prices. In addition we identify consumer and product characteristics that explain the variations in price k...

    The typical model of retail pricing for produce products assumes retailers set price equal to the farm price plus a certain markup. However, observations from scanner data indicate a large degree of price dispersion in the grocery retailing market. In addition to markup pricing behavior, we document three alternative leading pricing patterns: fixed (constant) pricing, periodic sale, and high-low pricing. Retail price variations under these alternative pricing regimes in general have little co...

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

  4. Spatial price dynamics: From complex network perspective

    Science.gov (United States)

    Li, Y. L.; Bi, J. T.; Sun, H. J.

    2008-10-01

    The spatial price problem means that if the supply price plus the transportation cost is less than the demand price, there exists a trade. Thus, after an amount of exchange, the demand price will decrease. This process is continuous until an equilibrium state is obtained. However, how the trade network structure affects this process has received little attention. In this paper, we give a evolving model to describe the levels of spatial price on different complex network structures. The simulation results show that the network with shorter path length is sensitive to the variation of prices.

  5. Marketplace pricing

    International Nuclear Information System (INIS)

    Anon.

    1991-01-01

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

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

  9. Pricing of temperature index insurance

    Che Mohd Imran Che Taib

    2012-01-01

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

In this study the authors use normative legal research. The data obtained in this study will be analyzed using qualitative normative method with inductive logic. Results from the study indicate that state shares subscription in the establishment of SOE or limited company with funds derived from State Budget are separated. Thus the government no longer has any authority in the field of civil law as a business entity. A clear separation of the status of country as business and as government organizer carries consequences. With the separation then there is clarity about the concept of the state financial losses. SOE as one form of business entity that aim to make a profit is a separate legal entity and has responsibilities that are separately anyway though formed and capital originating from the state finances and the loss of one transaction or in legal entity cannot be categorized as a state finance loss because the state has functioned as a private legal entity.

    Full Text Available The transition process from the subscription model to the open access model in the world of scholarly publishing brings a variety of challenges to libraries. Within this evolving landscape, the present article takes a focus on budget control for both subscription and publication expenditure with the opportunity to enable the shift from one to the other. To reach informed decisions with a solid base of data to be used in negotiations with publishers, the diverse already-existing systems for managing publications costs and for managing journal subscriptions have to be adapted to allow comprehensive reporting on publication expenditure and subscription expenditure. In the case presented here, two separate systems are described and the establishment of joint reporting covering both these systems is introduced. Some of the results of joint reporting are presented as an example of how such a comprehensive monitoring can support management decisions and negotiations. On a larger scale, the establishment of the National Open Access Monitor in Germany is introduced, bringing together a diverse range of data from several already-existing systems, including, among others, holdings information, usage data, and data on publication fees. This system will enable libraries to access all relevant data with a single user interface.

  1. Market, trading and coal price

    International Nuclear Information System (INIS)

    Muller, J.C.; Cornot-Gandolphe, S.; Labrunie, L.; Lemoine, St.; Vandijck, M.

    2006-01-01

    The coal world experienced a true upheaval in the past five years World coal consumption went up 28 % between 2000 and 2005, as a result of the strong growth in Chinese demand. The growth should continue in the coming years: electrical plant builders' orders are mainly for coal. The regained interest in coal is based on the constraints experienced by competing energies (increase in oil and natural gas prices, geopolitical uncertainties, supply difficulties) and by the abundant reserves of coal in the world and the competitiveness of its price. The strong growth in world coal demand comes with a change in rules governing steam coal trading. While long term bilateral agreements were most common until the late nineties, there has been a true revolution in coal marketing since 2000: spot contracts, stock exchange emergence and futures contracts, price indexes. In a few years, the steam coal market has become a true commodities market, overtaking many more goods. The price of coal has also gone through strong variations since 2003. Whereas the price had been stable for decades, in 2004 the strong increase in China' s demand for coal and iron ore resulting in transport shortage, caused a strong increase in CAF coal prices. Since then, prices have gone down, but remain higher than the Eighties and Nineties levels. In spite of the increase, coal remains available at more competitive prices than its competing energies.

    2014-10-01

    Higher prices reduce consumption and initiation of tobacco products. A minimum price law that establishes a high statutory minimum price and prohibits the industry's discounting tactics for tobacco products is a promising pricing strategy as an alternative to excise tax increases. Although some states have adopted minimum price laws on the basis of statutorily defined price "markups" over the invoice price, existing state laws have been largely ineffective at increasing the retail price. We analyzed 3 new variations of minimum price laws that hold great potential for raising tobacco prices and reducing consumption: (1) a flat rate minimum price law similar to a recent enactment in New York City, (2) an enhanced markup law, and (3) a law that incorporates both elements.

  6. Co-generation of hydrogen from nuclear and wind: the effect on costs of realistic variations in wind capacity and power prices

    International Nuclear Information System (INIS)

    Miller, A.I.; Duffey, R.

    2005-01-01

    Can electricity from high-capacity nuclear reactors be blended with the variable output of wind turbines to produce electrolytic hydrogen competitively? Future energy hopes and emissions reduction scenarios place significant reliance on renewables, actually meaning largely new wind power both onshore and offshore. The opportunity exists for a synergy between high capacity factor nuclear plants and wind power using hydrogen by both as a 'currency' for use in transportation and industrial processing. But this use of hydrogen needs to be introduced soon. To be competitive with alternative sources, hydrogen produced by conventional electrolysis requires low-cost electricity (likely <2.5 Cent US/kW.h). One approach is to operate interruptibly allowing an installation to sell electricity when the grid price is high and to make hydrogen when it is low. Our previous studies have shown that this could be a cost-competitive approach with a nuclear power generator producing electricity around 3 Cent US/kW.h. Although similar unit costs are projected for wind-generated electricity, idleness of the hydrogen production (electrolysis) facility due to the variability of wind generated electricity imposes a serious cost penalty. This paper reports our latest results on the potential economics of blending electricity from nuclear and wind sources by using wind-generated power, when available, to augment the current through electrolysis equipment that is primarily nuclear-powered. A voltage penalty accompanies the higher current. A 10% increase in capital cost for electrolysis equipment enables it to accommodate the higher rate of hydrogen generation, while still being substantially cheaper than the capital cost of wind-dedicated electrolysis. Real-time data for electricity costs have been combined with real-time wind variability in our NuWind model. The variability in wind fields between sites was accommodated by assuming an average wind speed that produced an average electricity

Considering that only about one third of the territory has been prospected to date, fuel supply for those nuclear plants, as far as uranium ore reserves are concerned, is already assured. Fuel cycle technology dominance also guarantees to the country a position in an exclusive group of nations. The BNP outlooks the expansion of the nuclear fuel cycle looking for independence of foreign sources of supply. Estimating the nuclear fuel cost from national fuel cycle cost is still difficult due to lack of real cost data. Based on these facts it is presented a sensibility analysis of the nuclear fuel cost, taking into consideration exchange rate variation and the investment in internal rate of return. (author)

  16. Taking the mystery out of gasoline prices

    2000-01-01

    Gasoline price variations in different markets of Canada are primarily driven by market forces, not necessarily by costs, according to a petroleum valuation consultant of the Newfoundland Department of Mines and Energy. Market forces include wholesale prices, the number and efficiency of stations in an area, companies' marketing strategies and customer buying preferences. Prices can be affected by any one of these forces at any time. The prediction is that wholesale prices will continue to be volatile in the next few months as the market adjusts to the changes in crude oil prices determined by OPEC as well as the summer season for gasoline. Changes in crude oil prices are usually reflected in the price of gasoline at the pump, although they do not necessarily move together. Demand which is an important factor in price, is cyclical in both the US and Canada, being lowest in the first quarter of the year, picking up during the second and third quarters with increased driving during good weather, and usually declining again in the fourth quarter with the onset of colder weather. Taxes are also a very significant component of the retail price of gasoline; in July 1998 the combined federal and provincial taxes accounted for 54 per cent of the average retail price of regular unleaded gasoline in Canada. Refining and marketing costs, the distance gasoline has to be transported to market, also influence prices at the pump

  17. ECONOMICAL PLANS EFFECTS ON CHARCOAL PRICES

    2007-06-01

    Full Text Available Energy is essential for human needs satisfaction. With the evolution of machinery, man becomes more and more dependent on the energy stocked in fossil fuels, comparatively to the primitive economy. Wood charcoal is a thermal-reducer used in Brazilian pig iron and steel industries, and its price is formed in an oligopsonic market. Over time, the charcoal prices have varied in function of endogenous and exogenous factors, needing, therefore, to be deflated so that they can be compared in two or more points in time. This work analyzed the variations of charcoal real prices, in national currency; compared and analyzed the real charcoal price in nominal and in real US Dollar and; analyzed the real prices of charcoal, comparatively to the real oil prices. The analyses were accomplished in the period from January 1975 to December 2002. The time series of charcoal prices, in domestic currency were deflated using IGP-DI, considering august, 1994=100, and charcoal prices were also converted to American dollar and deflated using CPI, considering the period 1982-84=100. It was compared, then, the real and nominal charcoal prices. It concluded that the real charcoal prices in Brazilian domestic currency, or in American dollar, presented a decreasing tendency along time. The inflationary disarray, in the 80´s and the first half of the 90 ´s, provoked a big price variation in the period; from the beginning the XXI century, charcoal prices were more influenced by the exchange rate; in the energy crisis period, charcoal prices suffered big changes that, however, did not persist along time.

    1996-01-01

    The article investigates gas pricing in the European procurement market and the wholesale markets of the most important EU consumer markets. It demonstrates that value-oriented pricing principles override cost-oriented pricing principles. For one thing, and independently of pricing principles, two- or three-part demand price systems or basic price systems are common. For another, the frequently encountered opportunities for the differentiation of prices show that as long as there is merely substitution competition instead of direct competition, gas suppliers have a certain degree of freedom in fixing their prices. By contrast, the introduction of direct competition in Great Britain has reduced suppliers' individual price fixing margins, because short-term supply and demand variations in the now created spot market are decisive for gas pricing.

    Full Text Available In music streaming services like Spotify, discrete pieces of music no longer has a price, as has traditionally been the case in music retailing, both analog and digital. This article discusses the theoretical and practical implications of this shift towards subscriptions, starting from a critical review of recent literature dealing with the commodification of music. The findings have a relevance that is not limited to music or digital media, but also apply more broadly on the study of commodification. At the theoretical level, the article compares two ways of defining the commodity, one structural (Marx, one situational (Appadurai, Kopytoff, arguing for the necessity of a theory that can distinguish commodities from all that which is not (yet commodified. This is demonstrated by taking Spotify as a case, arguing that it does not sell millions of different commodities to its users, but only one: the subscription itself. This has broad economic and cultural implications, of which four are highlighted: (1 The user of Spotify has no economic incentive to limit music listening, because the price of a subscription is the same regardless of the quantity of music consumed. (2 For the same reason, Spotify as a company cannot raise its revenues by making existing customers consume more of the product, but only by raising the number of subscribers, or by raising the price of a subscription. (3 Within platforms like Spotify, it is not possible to use differential pricing of musical recordings, as has traditionally been the case in music retail. Accordingly, record companies or independent artists hence can no longer compete for listeners by offering their music at a discount. (4 Within the circuit of capital. Spotify may actually be better understood as a commodity producer than as a distributor, implying a less symbiotic relationship to the recorded music industry.

    The aims of this study were to (i) assess the expectations of general practice departments regarding health sciences libraries' subscriptions to journals and (ii) describe the current general practice journal collections of health sciences libraries. A cross-sectional survey was distributed electronically to the thirty-five university general practice departments in France. General practice departments were asked to list ten journals to which they expected access via the subscriptions of their health sciences libraries. A ranked reference list of journals was then developed. Access to these journals was assessed through a survey sent to all health sciences libraries in France. Adequacy ratios (access/need) were calculated for each journal. All general practice departments completed the survey. The total reference list included 44 journals. This list was heterogeneous in terms of indexation/impact factor, language of publication, and scope (e.g., patient care, research, or medical education). Among the first 10 journals listed, La Revue Prescrire (96.6%), La Revue du Praticien-Médecine Générale (90.9%), the British Medical Journal (85.0%), Pédagogie Médicale (70.0%), Exercer (69.7%), and the Cochrane Database of Systematic Reviews (62.5%) had the highest adequacy ratios, whereas Family Practice (4.2%), the British Journal of General Practice (16.7%), Médecine (29.4%), and the European Journal of General Practice (33.3%) had the lowest adequacy ratios. General practice departments have heterogeneous expectations in terms of health sciences libraries' subscriptions to journals. It is important for librarians to understand the heterogeneity of these expectations, as well as local priorities, so that journal access meets users' needs.

    Pozen, Alexis

    2015-01-01

    The objective was to evaluate the magnitude of various contributors to outpatient commercial colonoscopy prices, including market- and provider-level factors, especially market share. We used adjudicated fee-for-service facility claims from a large commercial insurer for colonoscopies occurring in hospital outpatient department or ambulatory surgery center from October 2005 to December 2012. Claims were matched to provider- and market-level data. Linear fixed effects regressions of negotiated colonoscopy price were run on provider, system, and market characteristics. Markets were defined as counties. There were 178,433 claims from 169 providers (104 systems). The mean system market share was 76% (SD = 0.34) and the mean real (deflated) price was US$1363 (SD = 374), ranging from US$169 to US$2748. For every percentage point increase in a system or individual facility's bed share, relative price increased by 2 to 4 percentage points; this result was stable across a number of specifications. Market population and price were also consistently positively related, though this relation was small in magnitude. No other factor explained price as strongly as market share. Price variation for colonoscopy was driven primarily by market share, of particular concern as the number of mergers increases in wake of the recession and the Affordable Care Act. Whether variation is justified by better quality care requires further research to determine whether quality is subsumed in prices. © The Author(s) 2015.

    Williamson, Nicholas A.

    2018-03-01

    This paper discusses the successful adoption of a subscription-based, open-access model of service delivery for a mass spectrometry and proteomics facility. In 2009, the Mass Spectrometry and Proteomics Facility at the University of Melbourne (Australia) moved away from the standard fee for service model of service provision. Instead, the facility adopted a subscription- or membership-based, open-access model of service delivery. For a low fixed yearly cost, users could directly operate the instrumentation but, more importantly, there were no limits on usage other than the necessity to share available instrument time with all other users. All necessary training from platform staff and many of the base reagents were also provided as part of the membership cost. These changes proved to be very successful in terms of financial outcomes for the facility, instrument access and usage, and overall research output. This article describes the systems put in place as well as the overall successes and challenges associated with the operation of a mass spectrometry/proteomics core in this manner.

  5. Nonlinear Pricing in Energy and Environmental Markets

    Science.gov (United States)

    Ito, Koichiro

    This dissertation consists of three empirical studies on nonlinear pricing in energy and environmental markets. The first investigates how consumers respond to multi-tier nonlinear price schedules for residential electricity. Chapter 2 asks a similar research question for residential water pricing. Finally, I examine the effect of nonlinear financial rewards for energy conservation by applying a regression discontinuity design to a large-scale electricity rebate program that was implemented in California. Economic theory generally assumes that consumers respond to marginal prices when making economic decisions, but this assumption may not hold for complex price schedules. The chapter "Do Consumers Respond to Marginal or Average Price? Evidence from Nonlinear Electricity Pricing" provides empirical evidence that consumers respond to average price rather than marginal price when faced with nonlinear electricity price schedules. Nonlinear price schedules, such as progressive income tax rates and multi-tier electricity prices, complicate economic decisions by creating multiple marginal prices for the same good. Evidence from laboratory experiments suggests that consumers facing such price schedules may respond to average price as a heuristic. I empirically test this prediction using field data by exploiting price variation across a spatial discontinuity in electric utility service areas. The territory border of two electric utilities lies within several city boundaries in southern California. As a result, nearly identical households experience substantially different nonlinear electricity price schedules. Using monthly household-level panel data from 1999 to 2008, I find strong evidence that consumers respond to average price rather than marginal or expected marginal price. I show that even though this sub-optimizing behavior has a minimal impact on individual welfare, it can critically alter the policy implications of nonlinear pricing. The second chapter " How Do

    In electricity markets, not only does the risk of substantial price variations over time exist, but so does the risk of price variations over space, as prices between locations can differ due to transmission congestion. To manage this risk, Contracts for Difference (CfDs), i.e., forwards on the spread between a particular area price and the (unconstrained) system price, were introduced at the Scandinavian electricity exchange Nord Pool at the end of 2000. We empirically investigate the pricing of these CfDs over the period 2001 through 2006 and find that CfD prices contain significant risk premia. Their sign and magnitude, however, differ substantially between areas and delivery periods, because areas are subject to transmission congestion to a varying extent. While the relation between risk premia and time-to-maturity is not uniform for CfDs, there is a negative relation for implied area and system forwards, which can be explained by the relative hedging demand of market participants. In addition, we find that risk premia of CfDs and implied area forwards vary systematically with the variance and skewness of the underlying spot prices. This confirms both implications of the Bessembinder and Lemmon [Bessembinder, H., Lemmon, M.L., 2002. Equilibrium pricing and optimal hedging in electricity forward markets. Journal of Finance, 57, 1347-1382] model. (author)

    A major factor influencing tobacco use is its price. Fiscal policies on tobacco are a key ingredient of any comprehensive control strategy, as they can be used to raise prices. The European Union (EU) developed directives to ensure some harmonisation of the fiscal pressure on tobacco across its member states. To provide a simple comparison of tobacco prices in the EU, adjusting for the purchasing power of each currency. For price comparisons, a 20 units pack of Marlboro was the reference product, and data refer to April 2000. Purchasing power parities (PPP) for each member state currency have been compiled. These are currency conversion rates, which convert to a common currency and equalise the purchasing power of different currencies. Nominal prices of a Marlboro pack for each member state, and a price index, estimated taking as reference the EU mean. Adjusted prices and an adjusted price index have been estimated using PPP. Nominal prices show wide variation, with the cheapest pack in Portugal (59) and the most expensive in the UK (196); the range of variation is three-fold. However, PPP adjusted prices reveal a different distribution. In three countries adjusted prices are outliers, but all other countries make two clusters, one around the average EU index of 100, the other around a lower value of 85. These results suggest that fiscal harmonisation policies in the EU do not have an even effect at reducing availability by its impact in price.

Orientation prices to competition (competitive pricing is the strategy most frequently used in countries with market economies and especially for exports. Moreover, in an economy dominated by market competition it cannot be ignored without certain risks the prices resulting from competition between products bidders. Companies that use this type of strategy seek to maintain a level of prices linked to that charged by other competitors (or exporting producers generally no longer covering production costs or demand, relying on the assumption that the average market price is a reasonable basis of costs. But the way how practical guidance and reporting to the competition in every price strategy, will be determined by the company's market position, by the available power and enjoyed prestige, objectives and prospects of its market share etc. according to these elements, there may be several versions of pricing strategies oriented to competitors.

    Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

  18. The market equilibrium of OPEC's pricing mechanism

    International Nuclear Information System (INIS)

    Hammoudeh, S.; Madan, V.

    1990-01-01

    At least twice a year, oil ministers of the Organization of the Petroleum Exporting Countries (OPEC) meet in Vienna or Geneva to adjust the group's output ceiling to eliminate discrepancies between the market price and the target price. If the market imbalances are persistent, then the target price is also adjusted. Often, OPEC's members differ in their assessment of future market demand for their oil and, thus, present different views on the need to adjust the output celing and the target price. During periods of downward pressures on oil prices, the high absorbers of capital (i.e., oil revenues) prefer a speedy downward adjustment to the celing, while the low absorbers are slow to react. However, in the event of tightening markets, the low absorbers usually respond by exceeding their quotas before agreeing on a ceiling adjustment. Therefore, OPEC nations have different desirable speeds of adjustment. This paper specifies and examines the stability of OPEC's pricing mechanism. It presents a strategy which would enable the organization to achieve a target price-based market equilibrium with increased rapidity through the appropriate manipulation of the speed of output ceiling adjustment. This strategy is applied using data on market and target prices, actual output, and output ceilings for the first quarter of 1991. The main finding is that, given the target price, OPEC's equilibrium market demand is significantly lower than the assigned output ceiling. Production should have been reduced by at least 3 million barrels a day for OPEC to realize the $21 per barrel target price in the first quarter of 1991. Seasonal factors can cause slight variations in this output but would not bring out compatibility between the target price and the output ceiling within a reasonable period of time unless OPEC follows an activist policy of output adjustment. 3 figs., 1 tab

    We examine electrical power price, and in particular its daily and average weekday vs. weekend pattern of change, for 14 deregulated markets. Power price in deregulated markets shows fundamentally different patterns. North American markets show a monotonic diurnal weekday price pattern, while all other markets studied show more than one price peak. Deregulated power markets differ in maximum vs. minimum daily average price and in average weekday to weekend price, in turn creating a different incentive for a consumer to time shift power consuming activities. Markets differ in the extent to which a small fraction of the days shapes the average diurnal pattern and value of price. Deregulated markets show a wide variation in the correlation between load and price. Some deregulated markets, most notably Britain and Spain, show patterns that are predictable and consistent, and hence that can encourage a customer to shape consumption behaviors. Other markets, for example South Australia, have patterns that are inconsistent and irregular, and hence are hard for a customer to interpret; a customer in such a market will have a higher incentive to escape risk through hedging mechanisms.

    Full Text Available Price control at macro level is part of integral macro marketing strategic control system, or more precisely, part of social marketing mix control. Price impact is direct, if it is regarded in the context of needs satisfaction, and indirect, within the context of resource allocation. These two patterns of price impact define control mechanism structuring. Price control in sense of its direct impact at process of need satisfaction should comprise qualitative and quantitative level of needs satisfaction at a given price level and its structure, informational dimension of price and different disputable forms of corporate pricing policies. Control of price allocation function is based at objectives of macro marketing system management in the area of resource allocation and the role of price as allocator in contemporary market economies. Control process is founded, on one hand, at theoretical models of correlation between price and demand in different market structures, and on the other hand, at complex limits that price as allocator has, and which make whole control process even more complex because of reduction of the degree of determinism in functioning of contemporary economic systems. Control of price allocation function must be continuous and dynamic process if it is to provide for convergence with environmental changes and if it is to provide for placing control systems at micro marketing levels in the function of socially valid objectives.

    Full Text Available Why are product prices in online markets dispersed in spite of very small search costs? To address this question, we construct a unique dataset from a Japanese price comparison site, which records price quotes offered by e-retailers as well as customers' clicks on products, which occur when they proceed to purchase the product. The novelty of our approach is that we seek to extract useful information on the source of price dispersion from the shape of price distributions rather than focusing merely on the standard deviation or the coefficient of variation of prices, as previous studies have done. We find that the distribution of prices retailers quote for a particular product at a particular point in time (divided by the lowest price follows an exponential distribution, showing the presence of substantial price dispersion. For example, 20 percent of all retailers quote prices that are more than 50 percent higher than the lowest price. Next, comparing the probability that customers click on a retailer with a particular rank and the probability that retailers post prices at a particular rank, we show that both decline exponentially with price rank and that the exponents associated with the probabilities are quite close. This suggests that the reason why some retailers set prices at a level substantially higher than the lowest price is that they know that some customers will choose them even at that high price. Based on these findings, we hypothesize that price dispersion in online markets stems from heterogeneity in customers' preferences over retailers; that is, customers choose a set of candidate retailers based on their preferences, which are heterogeneous across customers, and then pick a particular retailer among the candidates based on the price ranking.

    In light of proposals to improve diets by shifting food prices, it is important to understand how price changes affect demand for various foods. We reviewed 160 studies on the price elasticity of demand for major food categories to assess mean elasticities by food category and variations in estimates by study design. Price elasticities for foods and nonalcoholic beverages ranged from 0.27 to 0.81 (absolute values), with food away from home, soft drinks, juice, and meats being most responsive to price changes (0.7-0.8). As an example, a 10% increase in soft drink prices should reduce consumption by 8% to 10%. Studies estimating price effects on substitutions from unhealthy to healthy food and price responsiveness among at-risk populations are particularly needed.

    Antiretroviral medicines (ARVs) are one of the most costly parts of HIV/AIDS treatment. Many countries are struggling to provide universal access to ARVs for all people living with HIV and AIDS. Although substantial price reductions of ARVs have occurred, especially between 2002 and 2008, achieving sustainable access for the next several decades remains a major challenge for most low- and middle-income countries. The objectives of the present study were twofold: first, to analyze global ARV prices between 2005 and 2008 and associated factors, particularly procurement methods and key donor policies on ARV procurement efficiency; second, to discuss the options of procurement processes and policies that should be considered when implementing or reforming access to ARV programs. An ARV-medicines price-analysis was carried out using the Global Price Reporting Mechanism from the World Health Organization. For a selection of 12 ARVs, global median prices and price variation were calculated. Linear regression models for each ARV were used to identify factors that were associated with lower procurement prices. Logistic regression models were used to identify the characteristics of those countries which procure below the highest and lowest direct manufactured costs. Three key factors appear to have an influence on a country's ARV prices: (a) whether the product is generic or not; (b) the socioeconomic status of the country; (c) whether the country is a member of the Clinton HIV/AIDS Initiative. Factors which did not influence procurement below the highest direct manufactured costs were HIV prevalence, procurement volume, whether the country belongs to the least developed countries or a focus country of the United States President's Emergency Plan For AIDS Relief. One of the principal mechanisms that can help to lower prices for ARV over the next several decades is increasing procurement efficiency. Benchmarking prices could be one useful tool to achieve this.

  20. Food Prices and Climate Extremes: A Model of Global Grain Price Variability with Storage

    Science.gov (United States)

    Otto, C.; Schewe, J.; Frieler, K.

    2015-12-01

    Extreme climate events such as droughts, floods, or heat waves affect agricultural production in major cropping regions and therefore impact the world market prices of staple crops. In the last decade, crop prices exhibited two very prominent price peaks in 2007-2008 and 2010-2011, threatening food security especially for poorer countries that are net importers of grain. There is evidence that these spikes in grain prices were at least partly triggered by actual supply shortages and the expectation of bad harvests. However, the response of the market to supply shocks is nonlinear and depends on complex and interlinked processes such as warehousing, speculation, and trade policies. Quantifying the contributions of such different factors to short-term price variability remains difficult, not least because many existing models ignore the role of storage which becomes important on short timescales. This in turn impedes the assessment of future climate change impacts on food prices. Here, we present a simple model of annual world grain prices that integrates grain stocks into the supply and demand functions. This firstly allows us to model explicitly the effect of storage strategies on world market price, and thus, for the first time, to quantify the potential contribution of trade policies to price variability in a simple global framework. Driven only by reported production and by long--term demand trends of the past ca. 40 years, the model reproduces observed variations in both the global storage volume and price of wheat. We demonstrate how recent price peaks can be reproduced by accounting for documented changes in storage strategies and trade policies, contrasting and complementing previous explanations based on different mechanisms such as speculation. Secondly, we show how the integration of storage allows long-term projections of grain price variability under climate change, based on existing crop yield scenarios.

  12. When the weather governs the price

    International Nuclear Information System (INIS)

    Braaten, Jan

    2003-01-01

    In the winter 2002-2003 the Nordic power market experienced a price shock: prices rose by a factor of eight during the autumn of 2002. This was caused above all by a record failure of the water influx to the entire Nordic hydropower system. But extreme cold and technical problems with import from the Continent aggravated the problem. The probability of so small influx in autumn is less than 0.5 per cent. The large variation in influx, in particular from one year to the next, create large price fluctuations which can be unpleasant for the consumers. At the same time the price mechanism is important for the proper balance between demand and supply. It was the high prices that last winter raised the import to Norway and Sweden and that caused idle fossil power stations to be restarted and the consumption to go down. A better energy balance in Norway and Sweden will increase the supply security, but in order to exploit the unstable hydropower resources well and to achieve an acceptable supply security in dry years flexibility is needed in production, consumption, and trade with the surrounding world. Most measures to increase the flexibility cost money, and it is probably impossible and economically undesirable to protect the consumers from all price shocks. It should be possible, however, for those who want stable expenses, to choose contracts with firm prices for the whole consumption or for part of it.

    The concerns that have been raised about gasoline prices in Newfoundland were addressed and the reasons why they differ significantly from one part of Newfoundland to another were examined. A research and investigation program was established to identify the factors contributing to the price of, and price variation in gasoline sold in the province. Companies directly involved in the gasoline retail business in the province were invited to answer an extensive questionnaire which asked detailed, confidential information concerning the company's operations. This report contains the results of the analysis of the responses, and provides a comprehensive picture of the operation of the petroleum industry. It also contains a series of recommendations for the government with respect to monitoring price fluctuations, gathering data about the industry, and constructing an independently owned and operated terminal storage facility. The report recommends against direct regulation. tabs., figs

  14. Capital Gains Taxation and House Price Fluctuations

    Recent years have seen large swings in house prices in many countries. Motivated by housing price variations, proposals for taxing capital gains on housing have repeatedly been put forth. The idea seems to be that such taxes would curb the redistribution occurring between those owning houses...... and those trying to get into the market for owner-occupied housing. Our paper shows that at least in simple settings, a tax on real capital gains on housing will only lead to even bigger price swings and will not be able to redistribute between people appearing on either side of the housing market.......Keywords: capital gains tax, housing market, price fluctuationsJEL-Classification: H23, H24, R 31.Addresses:...

  15. Price-elastic demand in deregulated electricity markets

    Energy Technology Data Exchange (ETDEWEB)

    Siddiqui, Afzal S.

    2003-05-01

    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.

    A new asset pricing model, the arbitrage pricing theory, has been developed as an alternative to the capital asset pricing model. The arbitrage pricing theory model is used to analyze the relationship between risk and return for agricultural assets. The major conclusion is that the arbitrage pricing theory results support previous capital asset pricing model findings that the estimated risk associated with agricultural assets is low. This conclusion is more robust for the arbitrage pricing th...

    In 1977 NASA published Shuttle Reimbursement Policies for Civil U.S. Government, DOD and Commercial and Foreign Users. These policies were based on the principle of total cost recovery over a period of time with a fixed flat price for initial period to time to enhance transition. This fixed period was to be followed with annual adjustments thereafter, NASA is establishing a new price for 1986 and beyond. In order to recover costs, that price must be higher than the initial fixed price through FY 1985. NASA intends to remain competitive. Competitive posture includes not only price, but other factors such as assured launch, reliability, and unique services. NASA's pricing policy considers all these factors.

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

    1988-12-01

    In the negotiation on raw coal price for 1988, which began at the end of 1987, Australia requested price rise of 4 - 5 dollars for the reason of rise of Australian dollars, conditions of mines, price drop in the past five years, and world supply/demand of coal. Japan insisted to maintain the price of preceding year. The talk ended in a dead lock which could last a long time. Negotiation on the Canadian coal price also encountered difficulties but an agreement was obtained in March as Japan accepted the increased price. After which, Japan and Australia agreed to raise the price by 2.90 dollars and an increase over last year. Producing countries also requested a wide price rise as 7.50 dollars for general coal, making in this area very difficult to progress. Finally, they agreed to raise the price by 6.30 dollars and the electric power utility in Japan responded by importing of U.S. coal, which has a lower heat output but is also cheaper. It depends on Australia for 70% of coal supply but started to diversify the source. 3 tabs.

    2018-05-12

    Drug costs are frequently estimated in economic analyses using wholesale acquisition cost (WAC), but what is the best approach to develop these estimates? Pharmaceutical manufacturers recently released transparency reports disclosing net price increases after accounting for rebates and other discounts. Our objective was to determine whether manufacturer net prices (MNPs) could approximate the discounted prices observed by the U.S. Department of Veterans Affairs (VA). We compared the annual, average price discounts voluntarily reported by three pharmaceutical manufacturers with the VA price for specific products from each company. The top 10 drugs by total sales reported from company tax filings for 2016 were included. The discount observed by the VA was determined from each drug's list price, reported as WAC, in 2016. Descriptive statistics were calculated for the VA discount observed and a weighted price index was calculated using the lowest price to the VA (Weighted VA Index), which was compared with the manufacturer index. The discounted price as a percentage of the WAC ranged from 9 to 74%. All three indexes estimated by the average discount to the VA were at or below the manufacturer indexes (42 vs. 50% for Eli Lilly, 56 vs. 65% for Johnson & Johnson, and 59 vs. 59% for Merck). Manufacturer-reported average net prices may provide a close approximation of the average discounted price granted to the VA, suggesting they may be a useful proxy for the true pharmacy benefits manager (PBM) or payer cost. However, individual discounts for products have wide variation, making a standard discount adjustment across multiple products less acceptable.

    2013-06-17

    This study compares ownership of health insurance among Ghanaian women with respect to wealth status and spatial location. We explore the overarching research question by employing geographic and proxy means targeting through interactive analysis of wealth status and spatial issues. The paper draws on the 2008 Ghana Demographic and Health Survey. Bivariate descriptive analysis coupled with binary logistic regression estimation technique was used to analyse the data. By wealth status, the likelihood of purchasing insurance was significantly higher among respondents from the middle, richer and richest households compared to the poorest (reference category) and these differences widened more profoundly in the Northern areas after interacting wealth with zone of residence. Among women at the bottom of household wealth (poorest and poorer), there were no statistically significant differences in insurance subscription in all the areas. The results underscore the relevance of geographic and proxy means targeting in identifying populations who may be need of special interventions as part of the efforts to increase enrolment as well as means of social protection against the vulnerable.

    Databases and data repositories provide essential functions for the research community by integrating, curating, archiving and otherwise packaging data to facilitate discovery and reuse. Despite their importance, funding for maintenance of these resources is increasingly hard to obtain. Fueled by a desire to find long term, sustainable solutions to database funding, staff from the Arabidopsis Information Resource (TAIR), founded the nonprofit organization, Phoenix Bioinformatics, using TAIR as a test case for user-based funding. Subscription-based funding has been proposed as an alternative to grant funding but its application has been very limited within the nonprofit sector. Our testing of this model indicates that it is a viable option, at least for some databases, and that it is possible to strike a balance that maximizes access while still incentivizing subscriptions. One year after transitioning to subscription support, TAIR is self-sustaining and Phoenix is poised to expand and support additional resources that wish to incorporate user-based funding strategies.

    The purpose of surgical literature is to publish the latest study results and to provide continuing medical education to readers. For optimal allocation of resources, institutional subscribers, professional societies and scientific publishers require structured data on reading and subscription preferences of potential readers of surgical literature. To obtain representative data on the preferences of German general and visceral surgeons regarding reading of and subscription to scientific journals. All members of the German Society for General and Visceral Surgery (DGAV) were invited to participate in a web-based survey. Questions were asked on the affiliation and position of the member, individual journal subscriptions, institutional access to scientific journals, preferences regarding electronic or print articles and special subscriptions for society members. Answers were descriptively analyzed. A total of 630 out of 4091 (15 %) members participated in the survey and 73 % of the respondents had at least 1 individual subscription to a scientific journal. The most frequently subscribed journal was Der Chirurg (47 % of respondents). The institutional access to journals was deemed insufficient by 48 % of respondents, predominantly in primary care hospitals and outpatient clinics. Almost half of the respondents gave sufficient importance to reading printed versions of articles for which they would pay extra fees. A group subscription for society members was perceived as advantageous as long as no relevant extra costs were incurred. This structured survey among members of the DGAV provides data on preferences regarding reading of and subscription to scientific journals.

  7. Animal health and price transmission along livestock supply chains.

    Science.gov (United States)

    Aragrande, M; Canali, M

    2017-04-01

    Animal health diseases can severely affect the food supply chain by causing variations in prices and market demand. Price transmission analysis reveals in what ways price variations are transmitted along the supply chain, and how supply chains of substitute products and different regional markets are also affected. In perfect markets, a price variation would be completely and instantaneously transmitted across the different levels of the supply chain: producers, the processing industry, retailers and consumers. However, empirical studies show that food markets are often imperfect, with anomalies or asymmetries in price transmission and distortions in the distribution of market benefits. This means, for instance, that a price increase at the consumer level may not be transmitted from retailers to processors and producers; yet, on the other hand, price falls may rapidly affect the upstream supply chain. Market concentration and the consequent exertion of market power in key segments of the supply chain can explain price transmission asymmetries and their distributional effects, but other factors may also be involved, such as transaction costs, scale economies, and imperfect information. During the bovine spongiform encephalopathy (BSE) crisis, asymmetric price transmission in the beef supply chain and related meat markets determined distributional effects among sectors. After the spread of the BSE food scare, the fall in demand marginally affected the price paid to retailers, but producers and wholesalers suffered much more, in both price reductions and the time needed to recover to precrisis demand. Price transmission analysis investigates how animal health crises create different economic burdens for various types of stakeholder, and provides useful socioeconomic insights when used with other tools.

    Values of current energy technology costs and prices, available from a variety of sources, can sometimes vary. While some of this variation can be due to differences in the specific materials or configurations assumed, it can also reflect differences in the definition and context of the terms "cost" and "price." This fact sheet illustrates and explains this latter source of variation in a case study of automotive lithium-ion batteries.

  12. Regional prices in the Swedish wood-fuel market

    International Nuclear Information System (INIS)

    Hillring, Bengt

    1999-01-01

    This paper analyses, through a statistical survey, the regional distribution of prices on the commercial wood-fuel market for district heating plants and the pellets market for single family houses. The existing market watch of the national Swedish wood-fuel market has been developed for both refined and unrefined wood-fuels. The last five years the trend for wood-fuel prices on the district heating market has been stable, with a slight increase in the price of refined wood-fuels. However, on the young and fast-growing household market for pellets, prices have increased 12% during the last three years. The distribution of prices for northern, middle and southern Sweden indicates differences within 5% between the regions. The limited price difference between Swedish regions are a product of a large domestic supply and an increasing trade among regions in Europe, putting pressure on prices. Regional differences, mirrored as transportation distances and local production costs are key factors that could explain this regional price variation. However, the development of a commercial market with less regulation tends to level out prices. Consumers on the household market purchase small quantities and do not have the same possibility as district heating companies to take advantage of the oversupply opportunity and thus face a faster price development. The weaker market position of the consumers also tends to give homogeneous prices between regions of the residential sector. (Author)

  13. Policy on energy pricing

    Energy Technology Data Exchange (ETDEWEB)

    Webb, M. G.

    1977-10-15

    Some economic principles of energy pricing in a market type economy in which there is consumer sovereignty are discussed. Thus resources will be allocated via the production processes in line with the preferences of consumers as revealed by their purchases of goods and services. Prices play the crucial role of coordinating instruments in this allocative process. It is assumed that all the energy industries are in the public sector. The following topics are discussed: the specification of objectives for the energy sector; marginal cost pricing; problems associated with the measurement of marginal costs; some aspects of the environmental costs associated with energy production and use, and some issues related to time differentiated tariffs; the modification of prices to achieve financial targets; and the use of energy prices to achieve income distribution objectives.

  14. Oil prices and the stock prices of alternative energy companies

    International Nuclear Information System (INIS)

    Henriques, Irene; Sadorsky, Perry

    2008-01-01

    Energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements. While it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies, there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices. In this paper, a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices, technology stock prices, oil prices, and interest rates. Our results show technology stock prices and oil prices each individually Granger cause the stock prices of alternative energy companies. Simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices. These results should be of use to investors, managers and policy makers. (author)

  15. Mind your pricing cues.

    Science.gov (United States)

    Anderson, Eric; Simester, Duncan

    2003-09-01

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

  1. Analysis of commodity prices with the particle filter

    Aiube, Fernando Antonio Lucena; Baidya, Tara Keshar Nanda; Tito, Edison Americo Huarsaya

    2008-01-01

    The behavior of commodities prices is fundamental to real-asset investment decisions, hedging, and pricing financial derivatives. Schwartz and Smith [Schwartz, E.S., Smith, J.E. (2000). Short term-variations and long-term dynamics in commodity prices. Management Science, 46, 893-911.] proposed a two-factor model for describing the stochastic processes of commodity prices, in which the two factors are short-term variations and equilibrium prices. These are both unobserved state variables that are estimated using the Kalman filter. The estimation is based on the observation of future prices for different maturities. The authors have carried out this process without incorporating jumps in the short-term variation of prices. Here we aim to demonstrate that the inclusion of jumps better explains the behavior of oil prices, and in fact creates difficulties in the estimation of state variables. This is because the variables become non-Gaussian so the Kalman filter is not recommended. Another methodology, called the particle filter, is more suitable in this case, and we describe its application in this article

    2016-01-01

    Price elasticity estimates of residential electricity demand vary widely across the energy economics and policy literature. In this paper, we seek to explain these findings using three nationwide datasets from the U.S. – the American Housing Survey, Forms EIA-861, and the Residential Energy Consumption Survey. We examine the role of the sample period, level of aggregation, use of panel data, use of instrumental variables, and inclusion of housing characteristics and capital stock. Our findings suggest that price elasticities have remained relatively constant over time. Upon splitting our panel datasets into annual cross sections, we do observe a negative relationship between price elasticities and the average price. Whether prices are rising or falling appears to have little effect on our estimates. We also find that aggregating our data can result in both higher and lower price elasticity estimates, depending on the dataset used, and that controlling for unit-level fixed effects with panel data generally results in more inelastic demand functions. Addressing the endogeneity of price and/or measurement error in price with instrumental variables has a small but noticeable effect on the price elasticities. Finally, controlling for housing characteristics and capital stock produces a lower price elasticity. - Highlights: • The price elasticity of residential electricity demand varies widely across studies. • We use three large datasets from the US to examine reasons for such wide variation. • Some assessed effects include aggregation, unobserved heterogeneity, and price trends. • Correcting for such issues can change the estimated price elasticity by 50–100%.

  3. Pricing of new vaccines.

    Lee, Bruce Y; McGlone, Sarah M

    2010-08-01

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

  4. Prospects for oil prices

    International Nuclear Information System (INIS)

    Stevens, P.

    1992-01-01

    The basic argument presented is that the oil price is set in an administrated market. The administration is undertaken by the controllers of excess capacity to produce crude oil. The extent to which the administrated price matches the market price is a function, first, of the strength and effectiveness of the market controller and, secondly, of the state of supply and demand and expectations in the market. Currently, the market is operating close to capacity, what limited excess capacity exists is located mainly in Saudi Arabia and the Saudi Arabians appear to be following a low price objective. While the Saudi Arabians pursue volume, the short term project, in the balance of a political upheaval, is that oil prices will remain below the $21 per barrel agreed in July 1990. There is a view that Saudi Arabia would take quick action to reverse a price collapse, but attention is drawn to previous miscalculations with respect to price collapse. Should political circumstances allow the return of Iraq to the oil market, then excess capacity within the Gulf members of OPEC will return and control will be much more difficult. (UK)

  6. Prospects for oil prices

    International Nuclear Information System (INIS)

    Caddy, P.

    1992-01-01

    It is argued that the wave in oil prices which occurred in 1991, although appearing to suggest price instability, in fact shows the opposite. Steady oscillation between a low price level that leads to new customers and a high price that encourages customers to switch to alternatives is a sign of a stable market. This relative stability was achieved against the background of the political upheaval in the USSR and Eastern Europe and its unpredictable consequences. Such political uncertainties to one side, the difficulties of assessing demand trends in the light of the imponderables of the state of the world economy and the weather are stressed. Despite these problems, the view is expressed that correct reading of signals up the supply chain by producers should ensure continued relative price stability. This is not to say that prices will stay exactly the same, just that they will be bound within a trading range set by anticipated consumer and producer responses to the fluctuating prices. (UK)

  7. Faculty Decisions on Serials Subscriptions Differ Significantly from Decisions Predicted by a Bibliometric Tool.

    Full Text Available Objective – To compare faculty choices of serials subscription cancellations to the scores of a bibliometric tool. Design – Natural experiment. Data was collected about faculty valuations of serials. The California Digital Library Weighted Value Algorithm (CDL-WVA was used to measure the value of journals to a particular library. These two sets of scores were then compared. Setting – A public research university in the United States of America. Subjects – Teaching and research faculty, as well as serials data. Methods – Experimental methodology was used to compare faculty valuations of serials (based on their journal cancellation choices to bibliometric valuations of the same journal titles (determined by CDL-WVA scores to identify the match rate between the faculty choices and the bibliographic data. Faculty were asked to select titles to cancel that totaled approximately 30% of the budget for their disciplinary fund code. This “keep” or “cancel” choice was the binary variable for the study. Usage data was gathered for articles downloaded through the link resolver for titles in each disciplinary dataset, and the CDL-WVA scores were determined for each journal title based on utility, quality, and cost effectiveness. Titles within each dataset were ranked highest to lowest using the CDL-WVA scores within each fund code, and then by subscription cost for titles with the same CDL-WVA score. The journal titles selected for comparison were those that ranked above the approximate 30% of titles chosen for cancellation by faculty and CDL-WVA scores. Researchers estimated an odds ratio of faculty choosing to keep a title and a CDL-WVA score that indicated the title should be kept. The p-value for that result was less than 0.0001, indicating that there was a negligible probability that the results were by chance. They also applied logistic regression to quantify the association between the numeric score of CDL-WVA and the binary variable

    Full Text Available The coupled additive and multiplicative (CAM noises model is a stochastic volatility model for derivative pricing. Unlike the other stochastic volatility models in the literature, the CAM model uses two Brownian motions, one multiplicative and one additive, to model the volatility process. We provide empirical evidence that suggests a nontrivial relationship between the kurtosis and skewness of asset prices and that the CAM model is able to capture this relationship, whereas the traditional stochastic volatility models cannot. We introduce a control variate method and Monte Carlo estimators for some of the sensitivities (Greeks of the model. We also derive an approximation for the characteristic function of the model.

  9. Fast food prices, obesity, and the minimum wage.

    Science.gov (United States)

    Cotti, Chad; Tefft, Nathan

    2013-03-01

    Recent proposals argue that a fast food tax may be an effective policy lever for reducing population weight. Although there is growing evidence for a negative association between fast food prices and weight among adolescents, less is known about adults. That any measured relationship to date is causal is unclear because there has been no attempt to separate variation in prices on the demand side from that on the supply side. We argue that the minimum wage is an exogenous source of variation in fast food prices, conditional on income and employment. In two-stage least-squares analyses, we find little evidence that fast food price changes affect adult BMI or obesity prevalence. Results are robust to including controls for area and time fixed effects, area time trends, demographic characteristics, substitute prices, numbers of establishments and employment in related industries, and other potentially related factors.

  10. Food Price Volatility and Decadal Climate Variability

    Science.gov (United States)

    Brown, M. E.

    2013-12-01

    The agriculture system is under pressure to increase production every year as global population expands and more people move from a diet mostly made up of grains, to one with more meat, dairy and processed foods. Weather shocks and large changes in international commodity prices in the last decade have increased pressure on local food prices. This paper will review several studies that link climate variability as measured with satellite remote sensing to food price dynamics in 36 developing countries where local monthly food price data is available. The focus of the research is to understand how weather and climate, as measured by variations in the growing season using satellite remote sensing, has affected agricultural production, food prices and access to food in agricultural societies. Economies are vulnerable to extreme weather at multiple levels. Subsistence small holders who hold livestock and consume much of the food they produce are vulnerable to food production variability. The broader society, however, is also vulnerable to extreme weather because of the secondary effects on market functioning, resource availability, and large-scale impacts on employment in trading, trucking and wage labor that are caused by weather-related shocks. Food price variability captures many of these broad impacts and can be used to diagnose weather-related vulnerability across multiple sectors. The paper will trace these connections using market-level data and analysis. The context of the analysis is the humanitarian aid community, using the guidance of the USAID Famine Early Warning Systems Network and the United Nation's World Food Program in their response to food security crises. These organizations have worked over the past three decades to provide baseline information on food production through satellite remote sensing data and agricultural yield models, as well as assessments of food access through a food price database. Econometric models and spatial analysis are used

    National health insurance schemes (NHIS) in developing countries and perhaps in developed countries as well is a considered a pro-poor intervention by helping to bridge the financial burden of access to quality health care. Perceptions of quality of health service could have immense impacts on enrolment. This paper shows how perception of service quality under Ghana's insurance programme contributes to health insurance subscription. The study used the 2014 Ghana Demographic and Health Survey (GDHS) dataset. Both descriptive proportions and binary logistic regression techniques were applied to generate results that informed the discussion. Our results show that a high proportion of females (33 %) and males (35 %) felt that the quality of health provided to holders of the NHIS card was worse. As a result, approximately 30 % of females and 22%who perceived health care as worse by holding an insurance card did not own an insurance policy. While perceptions of differences in quality among females were significantly different (AOR = 0.453 [95 % CI = 0.375, 0.555], among males, the differences in perceptions of quality of health services under the NHIS were independent in the multivariable analysis. Beyond perceptions of quality, being resident in the Upper West region was an important predictor of health insurance ownership for both males and females. For such a social and pro-poor intervention, investing in quality of services to subscribers, especially women who experience enormous health risks in the reproductive period can offer important gains to sustaining the scheme as well as offering affordable health services.

    This report describes the systems for uranium price reporting currently available to the uranium industry. The report restricts itself to prices for U 3 O 8 natural uranium concentrates. Most purchases of natural uranium by utilities, and sales by producers, are conducted in this form. The bulk of uranium in electricity generation is enriched before use, and is converted to uranium hexafluoride, UF 6 , prior to enrichment. Some uranium is traded as UF 6 or as enriched uranium, particularly in the 'secondary' market. Prices for UF 6 and enriched uranium are not considered directly in this report. However, where transactions in UF 6 influence the reported price of U 3 O 8 this influence is taken into account. Unless otherwise indicated, the terms uranium and natural uranium used here refer exclusively to U 3 O 8 . (author)

    International Nuclear Information System (INIS)

    1998-06-01

    The market does not create a price for environmental pollution for the simple reason that there is no market for the environment. What can be done is to calculate shadow prices for environmental pollution, which is achieved by calculating the price that would arise if there would be a market for the environment. In applying this method, it generally proves to be necessary to base calculations on government environmental targets. Using available research data, the method is used to calculate shadow prices for a number of key pollutants. The present report is based on the CE studies 'Schaduwprijzen Prioriterings Methodiek (SPM)' (1997), commissioned by ICI Holland BV, and 'De prijs van Milieuvervuiling' (1997), commissioned by KNP BT Packaging

    . With the existence of a liquid market for derivatives with variance as underlying, such as VIX options, VIX futures and a well-developed over-the-counter market for options on variance swaps, it is important to consider models that are able to fit these markets while consistently pricing vanilla options...... financial models, and most importantly, to be aware of their limitations. Following that belief, this thesis consists of three independent and self-contained papers, all dealing with topics in derivatives pricing. The first paper considers the pricing of traffic light options, which are appropriate...... the market for multivariate credit instruments, we take a step back and focus on single-name default modeling and introduce two new model classes for modeling of the default time of a company.

  5. Analysis of transmission elasticity of international prices for sugar prices in Brazil: an application of the Structural Model

    Directory of Open Access Journals (Sweden)

    Mario Antonio Margarido

    2018-01-01

    Full Text Available This study aims to determine and analyze the spatial elasticity (or horizontal of price transmission between international sugar prices and the average price received by the Brazilian exporter of sugar, using the Structural Model. The data used are from January/2004 to November/2015. As a result, variations of 1% in the international sugar price are transmitted to the average price received by Brazilian sugar exporters with a magnitude of 0.3% on average, setting inelastic relationship between the two variables and, consequently, the non-occurrence of the law of one price. So, there are mechanisms in this market that are hindering the full functioning of the arbitration. This situation is not unusual, because the sugar is one of the most commercially protected product and suffer much interference.

  6. Higher prices, higher quality? Evidence from German nursing homes.

    Science.gov (United States)

    Herr, Annika; Hottenrott, Hanna

    2016-02-01

    This study investigates the relationship between prices and quality of 7400 German nursing homes. We use a cross section of public quality reports for all German nursing homes, which had been evaluated between 2010 and 2013 by external institutions. Our analysis is based on multivariate regressions in a two stage least squares framework, where we instrument prices to explain their effect on quality controlling for income, nursing home density, demographics, labour market characteristics, and infrastructure at the regional level. Descriptive analysis shows that prices and quality do not only vary across nursing homes, but also across counties and federal states and that quality and prices correlate positively. Second, the econometric analysis, which accounts for the endogenous relation between negotiated price and reported quality, shows that quality indeed positively depends on prices. In addition, more places in nursing homes per people in need are correlated with both lower prices and higher quality. Finally, unobserved factors at the federal state level capture some of the variation of reported quality across nursing homes. Our results suggest that higher prices increase quality. Furthermore, since reported quality and prices vary substantially across federal states, we conclude that the quality and prices of long-term care facilities may well be compared within federal states but not across.

    Fan Shu; Hyndman, Rob J.

    2011-01-01

    In this paper, the price elasticity of electricity demand, representing the sensitivity of customer demand to the price of electricity, has been estimated for South Australia. We first undertake a review of the scholarly literature regarding electricity price elasticity for different regions and systems. Then we perform an empirical evaluation of the historic South Australian price elasticity, focussing on the relationship between price and demand quantiles at each half-hour of the day. This work attempts to determine whether there is any variation in price sensitivity with the time of day or quantile, and to estimate the form of any relationships that might exist in South Australia. - Highlights: → We review the scholarly literature on electricity own-price elasticity for different regions and systems. → We use annual log-linear econometric models of the electricity demand to estimate the historic South Australian price elasticity. → We focus on the relationship between price and demand quantiles at each half-hour of the day. → The overall price elasticity in South Australia ranges from -0.363 to -0.428.

  12. Oil price volatility and the asymmetric response of gasoline prices to oil price increases and decreases

    International Nuclear Information System (INIS)

    Radchenko, S.

    2005-01-01

    This paper analyzes the effect of volatility in oil prices on the degree of asymmetry in the response of gasoline prices to oil price increases and decreases. Several time series measures of the asymmetry between the responses of gasoline prices to oil price increases and decreases and several measures of the oil price volatility are constructed. In all models, the degree of asymmetry in gasoline prices declines with an increase in oil price volatility. The results support the oligopolistic coordination theory as a likely explanation of the observed asymmetry and are not consistent with the standard search theory and the search theory with Bayesian updating.

  13. Is the price effect on fuel consumption symmetric? some evidence from an empirical study

    International Nuclear Information System (INIS)

    Sentenac Chemin, E.

    2009-04-01

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

    Eide, V; Gaivoronski, Alexei; Huuse, H; Streit-Bianchi, M; Le Goff, J M

    2006-01-01

    This Master thesis develops a framework for the pricing of licenses on technology, suitable for a Technology Transfer (TT) context that is characterized by a goal of dissemination, early-stage technologies, limited market information, and great variations between technologies. The chosen context is defined by comparing the policy and the specificity of the initial recipient, CERN, to other public research institutions, thereby aiming at the development of a general framework. A conceptual model of the framework is thereafter developed to accommodate considerations of all the indicated characteristics through three main subparts: 1)~the target price, 2)~the walk-away point, and 3)~the royalty structure. For estimation of a suitable target price, valuation methodologies from academic and business literature are reviewed and discussed with regard to their suitability for the chosen TT context, thus selecting six methods of different approaches and varying information dependency. A method for quantifying the appr...

  20. Estimating the commodity market price of risk for energy prices

    International Nuclear Information System (INIS)

    Kolos, Sergey P.; Ronn, Ehud I.

    2008-01-01

    The purpose of this paper is to estimate the ''market price of risk'' (MPR) for energy commodities, the ratio of expected return to standard deviation. The MPR sign determines whether energy forward prices are upward- or downward-biased predictors of expected spot prices. We estimate MPRs using spot and futures prices, while accounting for the Samuelson effect. We find long-term MPRs generally positive and short-term negative, consistent with positive energy betas and hedging, respectively. In spot electricity markets, MPRs in Day-Ahead Prices agree with short-dated futures. Our results relate risk premia to informed hedging decisions, and futures prices to forecast/expected prices.

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

    Directory of Open Access Journals (Sweden)

    David Bouras

    2017-07-01

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

Delivered pricing systems emerge in equilibrium in highly monopolistic and highly competitive industries, while FOB is used in intermediate market structures. The fact driving this result is that delivered pricing policies allow spatial price discrimination...

    Along with the proliferation of Open Access (OA) publishing, the interest for comparing the scientific quality of studies published in OA journals versus subscription journals has also increased. With our study we aimed to compare the methodological quality and the quality of reporting of primary epidemiological studies and systematic reviews and meta-analyses published in OA and non-OA journals. In order to identify the studies to appraise, we listed all OA and non-OA journals which published in 2013 at least one primary epidemiologic study (case-control or cohort study design), and at least one systematic review or meta-analysis in the field of oncology. For the appraisal, we picked up the first studies published in 2013 with case-control or cohort study design from OA journals (Group A; n = 12), and in the same time period from non-OA journals (Group B; n = 26); the first systematic reviews and meta-analyses published in 2013 from OA journals (Group C; n = 15), and in the same time period from non-OA journals (Group D; n = 32). We evaluated the methodological quality of studies by assessing the compliance of case-control and cohort studies to Newcastle and Ottawa Scale (NOS) scale, and the compliance of systematic reviews and meta-analyses to Assessment of Multiple Systematic Reviews (AMSTAR) scale. The quality of reporting was assessed considering the adherence of case-control and cohort studies to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) checklist, and the adherence of systematic reviews and meta-analyses to Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. Among case-control and cohort studies published in OA and non-OA journals, we did not observe significant differences in the median value of NOS score (Group A: 7 (IQR 7-8) versus Group B: 8 (7-9); p = 0.5) and in the adherence to STROBE checklist (Group A, 75% versus Group B, 80%; p = 0.1).

    Using a household survey conducted in 2014, this study estimates price elasticity of demand (PED) for beer, country liquor and spirits in India. Ordinary least-square models were used to estimate the responsiveness in alcohol demand due to price change. A large number of control variables were included to adjust for potential confounding in the model. Inter-district variation in alcohol consumption is adjusted for by including district fixed effects. Alcohol prices are negatively associated with demand for alcoholic beverages. The PED ranged from -0.14 for spirits to -0.46 for country liquor. Low level of education was positively associated with spirits consumption. The magnitude of elasticity varied by rural-urban, education and gender. Results indicate that a policy mix of price controls and awareness campaigns would be most effective in tackling the adverse effects of harmful drinking in India. The demand for beer, country liquor and spirits is negatively associated with its own price. The elasticity estimates ranged from -0.14 for spirits to -0.44 for country liquor. The elasticity estimates varied by rural-urban, gender and by education levels of the drinkers. © The Author 2017. Medical Council on Alcohol and Oxford University Press. All rights reserved

    This paper examines the impact of local (county-level) house prices on individual self-reported mental health using individual level data from the United States Behavioral Risk Factor Surveillance System between 2005 and 2011. Exploiting a fixed-effects model that relies on within-county variations, relative to the corresponding changes in other counties, I find that while individuals are likely to experience worse self-reported mental health when local house prices decline, this association is most pronounced for individuals who are least likely to be homeowners. This finding is not consistent with a prediction from a pure wealth mechanism but rather with the hypothesis that house prices act as an economic barometer. I also demonstrate that the association between self-reported mental health and local house prices is not driven by unemployment or foreclosure. The primary result-that lower local house prices have adverse impact on self-reported mental health of homeowners and renters-is consistent with studies using data from the United Kingdom.

  10. Quantity precommitment and price matching

    DEFF Research Database (Denmark)

    Tumennasan, Norovsambuu

    We revisit the question of whether price matching is anti-competitive in a capacity constrained duopoly setting. We show that the effect of price matching depends on capacity. Specifically, price matching has no effect when capacity is relatively low, but it benefits the firms when capacity...... is relatively high. Interestingly, when capacity is in an intermediate range, price matching benefits only the small firm but does not affect the large firm in any way. Therefore, one has to consider capacity seriously when evaluating if price matching is anti-competitive. If the firms choose their capacities...... simultaneously before pricing decisions, then the effect of price matching is either pro-competitive or ambiguous. We show that if the cost of capacity is high, then price matching can only (weakly) decrease the market price. On the other hand, if the cost of capacity is low, then the effect of price matching...

    The liberation of prices for the standard gasoline and ACPM, that was given starting from January of 1.999, it outlines uncertainties on the possible prices evolution, along the supply chain until the final user, in comparison with the system previous of control and adjustment. This article presents an approach to the possible evolution of the gasoline motor prices during 1.999, in their different components. It makes it from the entrance to the producer until when one sells the public to a maximum price that includes the super tax. Additionally, it makes a preliminary calculation of the impact of the prices prospective month to month on the cost of transport of ECOPETROL revenues and the Nation revenues. The prospective annual percentage variation is presented from the entrance to the producer and of the other components of the price of the standard gasoline motor in different scenarios of the rate variation. In the most probable scenario, a variation is expected from the entrance to the producing of 1,9% and an increment in the sale price to the public, without including the super tax, of 12,6%

    Food prices may affect diet and weight gain among youth and lead to geographic disparities in obesity. This paper examines the association between regional prices and consumption frequency of fruit/vegetables and snack items among elementary school children in the USA. Observational study using individual-level survey data of fifth-grade children (average age 11 years) and regional food prices based on store visits in 2004. Dependent variables are self-reported consumption frequency in fifth grade; primary explanatory variables are metropolitan area food prices relative to cost of living. Multivariate regression analysis. Price variation across metropolitan areas exists, and lower real prices for vegetables and fruits predict significantly higher intake frequency. Higher dairy prices predict lower frequency of milk consumption, while higher meat prices predict increased milk consumption. Similar price effects were not found for fast food or soft drink consumption. The geographic variation in food prices across the USA is sufficiently large to affect dietary patterns among youth for fruit, vegetables and milk. The price variation is either too small to affect children's consumption frequency of fast food or soft drinks, or the consumption of these foods is less price sensitive.

    that the expected return to the distant-future cash flows increases by more in bad times than the expected return to near-future cash flows does. This new stylized fact is important for understanding why the expected return on the market portfolio as a whole varies over time. In addition, it has strong implications...... for which economic model that drives the return to stocks. Indeed, I find that none of the canonical asset pricing models can explain this new stylized fact while also explaining the previously documented facts about stock returns. The second chapter, called Conditional Risk, studies how the expected return...... on individual stocks is influenced by the fact that their riskiness varies over time. We introduce a new ”conditional-risk factor”, which is a simple method for determining how much of the expected return to individual stocks that can be explained by time variation in their market risk, i.e. market betas.

    Price bubble arises when the price of an asset exceeds the asset's fundamental value, that is, the present value of future dividend payments. The important result of Santos and Woodford (1997) says that price bubbles cannot exist in equilibrium in the standard dynamic asset pricing model with rational agents as long as assets are in strictly positive supply and the present value of total future resources is finite. This paper explores the possibility of asset price bubbles when either one of ...

    International Nuclear Information System (INIS)

    Alba, P.

    2000-01-01

    Statistical analysis cannot, alone, provide an oil price forecast. So, one needs to understand the fundamental phenomena which control the past trends since the end of world war II After a first period during which oil, thanks to its abundance, was able to increase its market share at the expense of other energies, the first oil shock reflects the rarefaction of oil resource with the tilting of the US production curve from growth to decline. Since then, the new situation is that of a ''cohabitation'' between oil and the other energies with the oil price, extremely volatile, reflecting the trial and error adjustment of the market share left to the other energies. Such a context may explain the recent oil price surge but the analogy between the US oil situation at the time of the first shock and that existing today for the world outside Middle East suggest another possibility, that of a structural change with higher future oil prices. The authors examine these two possibilities, think that the oil price will reflect both as long as one or the other will not become proven, and conclude with a series of political recommendations.

    Science.gov (United States)

    Baker, W; Marn, M; Zawada, C

    2001-02-01

    Companies generally have set prices on the Internet in two ways. Many start-ups have offered untenably low prices in a rush to capture first-mover advantage. Many incumbents have simply charged the same prices on-line as they do off-line. Either way, companies are missing a big opportunity. The fundamental value of the Internet lies not in lowering prices or making them consistent but in optimizing them. After all, if it's easy for customers to compare prices on the Internet, it's also easy for companies to track customers' behavior and adjust prices accordingly. The Net lets companies optimize prices in three ways. First, it lets them set and announce prices with greater precision. Different prices can be tested easily, and customers' responses can be collected instantly. Companies can set the most profitable prices, and they can tap into previously hidden customer demand. Second, because it's so easy to change prices on the Internet, companies can adjust prices in response to even small fluctuations in market conditions, customer demand, or competitors' behavior. Third, companies can use the clickstream data and purchase histories that it collects through the Internet to segment customers quickly. Then it can offer segment-specific prices or promotions immediately. By taking full advantage of the unique possibilities afforded by the Internet to set prices with precision, adapt to changing circumstances quickly, and segment customers accurately, companies can get their pricing right. It's one of the ultimate drivers of e-business success.

  7. Comparative analysis of features of Polish and Lithuanian Day-ahead electricity market prices

    International Nuclear Information System (INIS)

    Bobinaite, Viktorija; Juozapaviciene, Aldona; Staniewski, Marcin; Szczepankowski, Piotr

    2013-01-01

    The goal of this article is to better understand the processes of electricity market price formation in Poland and Lithuania through an analysis of the features (volatility and spikes) of Lithuanian and Polish day-ahead electricity market prices and to assess how acquired electricity price features could affect the achievement of the main goals of the national energy policy. The following indicators have been calculated to determine electricity market price volatility: the oscillation coefficient, the coefficient of variation, an adjusted coefficient of variation, the standard deviation indicator, the daily velocity indicator (based on the overall average price) and the daily velocity indicator (based on the daily average price). Critical values for electricity market price have been calculated to evaluate price spikes. This analysis reveals that electricity market-price volatility is moderate in Poland and high in Lithuania. Electricity price spikes have been an observable phenomenon both in Lithuanian and in Polish day-ahead electricity markets, but they are more common in Lithuania, encompassing 3.15% of the time period analysed in Poland and 4.68% of the time period analysed in Lithuania. Volatile, spiking and increasing electricity prices in day-ahead electricity markets in Lithuania and Poland create preconditions and substantiate the relevance of implementation of the national energy policies and measures. - Highlights: • Moderate and seasonal volatility. • spiking market price and. • stable average price

  8. Is the price effect on fuel consumption symmetric? Some evidence from an empirical study

    Sentenac-Chemin, Elodie

    2012-01-01

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

    2006-12-01

    Full Text Available Volatility swaps are contingent claims on future realized volatility. Variance swaps are similar instruments on future realized variance, the square of future realized volatility. Unlike a plain vanilla option, whose volatility exposure is contaminated by its asset price dependence, volatility and variance swaps provide a pure exposure to volatility alone. This article discusses the risk-neutral valuation of volatility and variance swaps based on the framework outlined in the Heston (1993 stochastic volatility model. Additionally, the Heston (1993 model is calibrated for foreign currency options traded at BMF and its parameters are used to price swaps on volatility and variance of the BRL / USD exchange rate.

  14. IS THE PRICE RIGHT? PRICING FOR LONG TERM PROFITABILITY

    Directory of Open Access Journals (Sweden)

    Andrea Erika NYÁRÁDI

    2007-01-01

    Full Text Available The way how we choose our pricing strategy has a significant impact on company’s success. Nowadays companies more and more adopt a new way of thinking in pricing, namely pricing for a long term period in order to bring higher profitability, to build an efficient pricing strategy. Marketers have only recently begun to focus seriously on effective pricing. These companies are the so called progressive companies. They have begun doing more than just worrying about pricing. To increase profitability many are abandoning traditional reactive pricing procedures in favor of proactive pricing, making explicit corporate decisions to change their focus to growth in top-line sales to growth in profitability. The long-term implications of price strategies are still under-researched, and managers should be aware of shifts in customer reactions that may result from frequent adoption of certain strategies. The company pricing strategy should be seen in relation to developments in the company variables, internal ones (capital strength, competencies, organizational conditions, efficiency of the work force etc. as well as external ones (customers, competitors, the technological development etc., adopting strategic pricing. In this paper I will present the most effective pricing strategies leading to long term profitability, and also suggest practical conditions for pricing strategies to maximize profit in the long run.

  15. The price of electricity from private power producers

    Energy Technology Data Exchange (ETDEWEB)

    Kahn, E.; Milne, A.; Kito, S.

    1993-10-01

    The long-term wholesale electricity market is becoming increasingly competitive. Bidding for power contracts has become a dominant form of competition in this sector. The prices which emerge from this process have not been documented and compared in a systematic framework. This paper introduces a method to make such comparisons and illustrates it on a small sample of projects. This results show a wide range of prices for what is essentially the same technology, gas-fired combined cycle generation. The price range seems greater than what could be explained by transmission cost differences between high and low cost regions. For the smaller sample of coal-fired projects, price variation is substantially less. Further data collection and analysis should be able to help isolate more clearly what market or cost factors are responsible for the observed variation.

  16. Electricity Price Forecasting Based on AOSVR and Outlier Detection

    2005-01-01

    Electricity price is of the first consideration for all the participants in electric power market and its characteristics are related to both market mechanism and variation in the behaviors of market participants. It is necessary to build a real-time price forecasting model with adaptive capability; and because there are outliers in the price data, they should be detected and filtrated in training the forecasting model by regression method. In view of these points, this paper presents an electricity price forecasting method based on accurate on-line support vector regression (AOSVR) and outlier detection. Numerical testing results show that the method is effective in forecasting the electricity prices in electric power market.

  17. Divisia amount and price index for energy consumption

    International Nuclear Information System (INIS)

    Bentzen, J.

    1993-01-01

    In connection with the calculation of total energy consumption related to aggregation of the individual fuel's combustion values, an alternative to Btu aggregation (combustion value measurement), designated the ''Divisia index'', is presented. This represents an economic measure for energy consumption. The Divisia index is demonstrated in relation to total national energy consumption and total energy consumption within the Danish housing sector and also with regard to the estimation of price and income elasticity within energy demand. It is only possible to utilize the Divisia index in relation to the last 20 years, which is the period where energy consumption has stagnated. The question of possible irreversible effects on energy consumption caused by large variations in energy prices is discussed. It is suggested that the reaction to a fall in prices is different and less significant than is the case with price rises. In the long term, results point at a reasonably high price elasticity within energy demand. (AB) (22 refs.)

  18. Financial barriers and pricing strategies related to participation in sports activities: the perceptions of people of low income.

    Steenhuis, Ingrid H M; Nooy, Steffie B C; Moes, Machiel J G; Schuit, Albertine J

    2009-11-01

    Physical activity levels in most affluent countries are low and many people do not meet the current recommendations. Particularly for people with a low income, economic strategies seem promising to stimulate taking part in sports activities. This study investigated the importance of economic restraints for taking part in sports activities as well as perceptions of low-income people toward different pricing interventions. A qualitative study was conducted, using semistructured, individual interviews with 27 low-income men and women. The framework approach was used to analyze the transcripts of the interviews. The respondents considered finances to be an important barrier for participating in sports activities, together with some individual barriers. Promising pricing strategies are a discount on the subscription to the fitness or sports club, a 1 month free trial, and free entrance to the swimming pool once a week. Pricing strategies may be a promising intervention to increase physical activity levels of low-income people. However, this study indicates that this should be coupled with an intervention directed at individual barriers. Some pricing strategies will be used and appreciated more by low-income people than other pricing strategies. In addition, pricing strategies should be tailored to individual needs and preferences.

    Low energy prices in Iran do not reflect economic costs. Further distortions exist in the tariff structures of most energy sources and in their relative prices. Price reform is a key policy element for achieving increased energy conservation and economic substitution. Subsidies should be made transparent and explained by the Government, and, when eliminated, they could be compensated by target measures or direct subsidies for low income households. Price reforms are under way, with some caution though, because of possible political and inflationary consequences. In order to better understand the need for price reforms a brief analysis of the current energy pricing policy is provided there. (author)

    2011-01-01

    Offshore wind offers a very large clean power resource, but electricity from the first US offshore wind contracts is costlier than current regional wholesale electricity prices. To better understand the factors that drive these costs, we develop a pro-forma cash flow model to calculate two results: the levelized cost of energy, and the breakeven price required for financial viability. We then determine input values based on our analysis of capital markets and of 35 operating and planned projects in Europe, China, and the United States. The model is run for a range of inputs appropriate to US policies, electricity markets, and capital markets to assess how changes in policy incentives, project inputs, and financial structure affect the breakeven price of offshore wind power. The model and documentation are made publicly available. - Highlights: → We calculate the Breakeven Price (BP) required to deploy offshore wind plants. → We determine values for cost drivers and review incentives structures in the US. → We develop 3 scenarios using today's technology but varying in industry experience. → BP differs widely by Cost Scenario; relative policy effectiveness varies by stage. → The low-range BP is below regional market values in the Northeast United States.

  8. Coal prices rise

    2001-01-01

    Coking and semi hard coking coal price agreements had been reached, but, strangely enough, the reaching of common ground on semi soft coking coal, ultra low volatile coal and thermal coal seemed some way off. More of this phenomenon later, but suffice to say that, traditionally, the semi soft and thermal coal prices have fallen into place as soon as the hard, or prime, coking coal prices have been determined. The rise and rise of the popularity of the ultra low volatile coals has seen demand for this type of coal grow almost exponentially. Perhaps one of the most interesting facets of the coking coal settlements announced to date is that the deals appear almost to have been preordained. The extraordinary thing is that the preordination has been at the prescience of the sellers. Traditionally, coking coal price fixing has been the prerogative of the Japanese Steel Mills (JSM) cartel (Nippon, NKK, Kawasaki, Kobe and Sumitomo) who presented a united front to a somewhat disorganised force of predominantly Australian and Canadian sellers. However, by the time JFY 2001 had come round, the rules of the game had changed

  14. Pricing Mining Concessions Based on Combined Multinomial Pricing Model

    Directory of Open Access Journals (Sweden)

    Chang Xiao

    2017-01-01

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

  18. Oil price prospects

    International Nuclear Information System (INIS)

    Toalster, J.

    1992-01-01

    In this paper, four different, popular approaches to the analysis of oil price movements will be considered and an alternative method will be proposed. Whilst we await the development of a rigorous theoretical framework within which to evaluate the phenomenon of oil price movements some progress may be effected by an amalgam of approaches, with the traditional supply and demand model being supplemented by observations regarding political and social developments in particular countries or regions, together with an assessment of emerging and prospective technological achievements. In this way it should be possible to identify the critical influences at work, from which it should also be possible to select either the single most important variable or combination of variables, affecting the oil price. Moreover, it is my belief that the crucial variables influencing the oil price almost certainly, are more likely to be political and social, rather than economic. In this context and notwithstanding the fact that there is only a minimal level of surplus productive capacity in the world oil industry at present (perhaps 1-2 million b/d albeit rising rapidly), it is reasonable to conclude that oil prices will average around $18-19 a barrel for North Sea Brent in 1992 and 1993, with oscillations of $2-4 a barrel either side, rising slightly in 1994 to $19-20 a barrel and to $20-21 a barrel in 1995. Thereafter, the most likely outcome is for a rise in line with inflation (say $ a barrel/annum) with no prospect of an upward spike, because demand will be weaker than most commentators expect up to the year 2000, whilst OPEC oil supplies will be substantially higher than the consensus forecast.

It is interesting to make clear the function of the price limits after IPOs. We firstly make a statistical analysis based on all the IPO stocks listed from 1990 to 2015. A high dependency exists between the activities in stock's IPO and various market environment. We also focus on the price dynamics in the first 40 trading days after the stock listed. We find that price limit system will delay the price movement, especially for the up-trend movements, which may lead to longer continuous price limit hits. Similar to our previous work, many results such as ;W; shape can be also observed in the future daily return after the price limit open. At last, we find most IPO measures show evident correlations with the following price limit hits. IPO stocks with lower first-day turnover and earning per share will be followed with a longer continuous price limit hits and lower future daily return under the newest trading rules, which give us a good way to estimate the occurrence of price limit hits and the following price dynamics. Our analysis provides a better understanding of the price dynamics after IPO events and offers potential practical values for investors.

    The industry standard Black-Scholes option pricing formula is based on the current value of the underlying security and other fixed parameters of the model. The Black-Scholes formula, with a fixed volatility, cannot match the market's option price; instead, it has come to be used as a formula for generating the option price, once the so called implied volatility of the option is provided as additional input. The implied volatility not only is an entire surface, depending on the strike price and maturity of the option, but also depends on calendar time, changing from day to day. The point of view adopted in this paper is that the instantaneous rate of return of the security carries part of the information that is provided by implied volatility, and with a few (time-independent) parameters required for a complete pricing formula. An option pricing formula is developed that is based on knowing the value of both the current price and rate of return of the underlying security which in physics is called velocity. Using an acceleration Lagrangian model based on the formalism of quantum mathematics, we derive the pricing formula for European call options. The implied volatility of the market can be generated by our pricing formula. Our option price is applied to foreign exchange rates and equities and the accuracy is compared with Black-Scholes pricing formula and with the market price.

  7. Declining subscriptions to the Maliando Mutual Health Organisation in Guinea-Conakry (West Africa): what is going wrong?

    Mutual Health Organisations (MHOs) are a type of community health insurance scheme that are being developed and promoted in sub-Saharan Africa. In 1998, an MHO was organised in a rural district of Guinea to improve access to quality health care. Households paid an annual insurance fee of about US$2 per individual. Contributions were voluntary. The benefit package included free access to all first line health care services (except for a small co-payment), free paediatric care, free emergency surgical care and free obstetric care at the district hospital. Also included were part of the cost of emergency transport to the hospital. In 1998, the MHO covered 8% of the target population, but, by 1999, the subscription rate had dropped to about 6%. In March 2000, focus groups were held with members and non-members of the scheme to find out why subscription rates were so low. The research indicated that a failure to understand the scheme does not explain these low rates. On the contrary, the great majority of research subjects, members and non-members alike, acquired a very accurate understanding of the concepts and principles underlying health insurance. They value the system's re-distributive effects, which goes beyond household, next of kin or village. The participants accurately point out the sharp differences that exist between traditional financial mechanisms and the principle of health insurance, as well as the advantages and disadvantages of both. The ease with which risk-pooling is accepted as a financial mechanism which addresses specific needs demonstrates that it is not, per se, necessary to build health insurance schemes on existing or traditional systems of mutual aid. The majority of the participants consider the individual premium of 2 US dollars to be fair. There is, however, a problem of affordability for many poor and/or large families who cannot raise enough money to pay the subscription for all household members in one go. However, the main reason for

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

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

    2017-06-01

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

  1. Exploring off-set pricing models and article deposit terms at King Abdullah University of Science & Technology (KAUST)

    KAUST Repository

    2018-04-09

    In the ‘normal’ world of retail and commerce you pay for an item and receive the item. In the world of academic journals you prepay for the item and you might receive the item and you might get some money back depending on what journals you did or didn’t receive. In the world of offset pricing you prepay, then you pay again, you sometimes use vouchers, you might get a discount (the following year) then you might get money back, or you might not. Are publishers knowingly placing barriers to off-set models, and not transparently offsetting the APCs to the subscription cost, in order to raise more income? Whether by design or accident it is a complex world which needs a time commitment, which not all librarians can give, to understand fully. The new model of scholarly communication, which leading universities (including KAUST) want to introduce, is based on shifting the subscription costs to publishing costs, not to double the payment channels to the publishers. Can we get to a mutually beneficial position where the author can deposit the accepted version of the article into the Institutional Repository without any embargo period as the institute is agreeing to pay the subscription fee on an ongoing basis? The required model does not adversely affect the vendors’ revenue. This presentation, based on KAUST’’s experience to date, will attempt to explain the different models of offset pricing while outlining KAUST’s dual approach, redirecting subscription money to publishing money and embedding open access terms in understandable language in our license agreements, to the problem. Why we have accepted IoP’s offset offer and not Springer’s, though we were considered among the first timers and important Institutions? Why is this important? Resolving the inherent complexities in offsetting models will save libraries money and also time wasted on tedious and unnecessary administration work. Researchers do not want to know about offsetting agreements nor

    Full Text Available In the first decades of the XX century the possibility of a particular newspaper having a high number of subscribers was, from the point of view of the newspaper publishers, the best guarantee of its stability. However it was not all advantages in a system which gave rise to numerous complaints and created a peculiar relationship with the subscriber. By various means —delivery men, the post and public establishments, principally— the subscription service continually generated situations illustrative of the level of development of the Spanish press in years in which progress accelerates and deficiencies and limitations also become apparent. Limitations which, particularly in an outlying region with mostly inadequate means of communication such as Asturias, could become one of the main factors delaying the establishment of a large press with mass-readership.

We have inherited from the communist system a very poor market of housing. The number of dwellings in 1990 in Albania was 219 dwellings per 1000 inhabitants and the useful floor space was 5 m² per person, but in Bulgaria number of dwellings per 1,000 people varies 465 and in Romania average useful floor space per person was 37 sq. The data used in this study are derived from the database of the World Bank, the Institute of Statistics, reports of Bank of Albania also from information provided individually on the ground and different sources. In this study is analyzed the relationship that exists between economic growth, remittances and the price of dwellings in Albania. The dependent variable is the average price of housing in major cities of Albania. Independent variables in the model are GDP per capita and the remittances. The Econometric model is a Linear Regress equation and the period are the years from 1998 to 2013. The model used is the statistical program EViews 6.0. Unfortunately the information let the desired, so we do not have an official detailed information on prices of Albanian real estate market.

    Crude oil prices climbed to new record levels on fears of a future loss of supplies from Iran as Washington stepped up its efforts to persuade Tehran to abandon its programme to produce nuclear fuel. IPE's December Brent contract set a new record for the exchange by trading at $75.80/bbl on 21st April. On the same day October WTI reached an all-time high of $77.30/bbl on Nymex. US product prices gained as refiners struggled to produce sufficient middle distillate. Alarmed by the rising retail price of gasoline, the US Senate debated a reduction in the already low US tax rate on motor spirit. The House of Representatives passed a measure to prohibit overcharging for petrol, diesel and heating oil, but Democrats rejected a Republican proposal to speed-up the process for approving new refineries. President George W Bush announced a temporary easing of new gasoline and diesel specifications (see 'Focus', March 2006) to allow more fuel to be produced. He also agreed to delay the repayment of some 2.1 mn bbl of crude oil lent to companies after last year's hurricanes from the Strategic Petroleum Reserve. California announced an inquiry into alleged overcharging for fuel by oil companies operating in the state. (author)

Qualsiasi analisi fruttuosa deve distinguere tra i vari tipi di mercati e merci in quanto, nel breve e lungo termine, i meccanismi di formazione dei prezzi e variazione dipendono dagli stessi. In questo lavoro , l'autore dedica particolare attenzione alla dicotomia tra materie prime e merci . Un'altra dicotomia è introdotta con riferimento al mercato del lavoro . La base logica per la doppia dicotomia è data dal grado di flessibilità , rispetto alla domanda , di prezzi e redditi .Although the concept of a general price level is of some limited use in purely statistical and descriptive studies, it is dangerous and deceptive in the field of theoretical analyses which aim at explaining price variations. Any fruitful analysis must distinguish between various types of markets and goods since, in the short and long run, the mechanisms of price formation and variation are dependent on such. In this work, the author devotes special attention to the dichotomy of raw materials and manufactures, a regards goods. Another dichotomy is introduced with reference to the labour market.

  14. Peer Review Quality and Transparency of the Peer-Review Process in Open Access and Subscription Journals.

    Science.gov (United States)

    Wicherts, Jelte M

    2016-01-01

    Recent controversies highlighting substandard peer review in Open Access (OA) and traditional (subscription) journals have increased the need for authors, funders, publishers, and institutions to assure quality of peer-review in academic journals. I propose that transparency of the peer-review process may be seen as an indicator of the quality of peer-review, and develop and validate a tool enabling different stakeholders to assess transparency of the peer-review process. Based on editorial guidelines and best practices, I developed a 14-item tool to rate transparency of the peer-review process on the basis of journals' websites. In Study 1, a random sample of 231 authors of papers in 92 subscription journals in different fields rated transparency of the journals that published their work. Authors' ratings of the transparency were positively associated with quality of the peer-review process but unrelated to journal's impact factors. In Study 2, 20 experts on OA publishing assessed the transparency of established (non-OA) journals, OA journals categorized as being published by potential predatory publishers, and journals from the Directory of Open Access Journals (DOAJ). Results show high reliability across items (α = .91) and sufficient reliability across raters. Ratings differentiated the three types of journals well. In Study 3, academic librarians rated a random sample of 140 DOAJ journals and another 54 journals that had received a hoax paper written by Bohannon to test peer-review quality. Journals with higher transparency ratings were less likely to accept the flawed paper and showed higher impact as measured by the h5 index from Google Scholar. The tool to assess transparency of the peer-review process at academic journals shows promising reliability and validity. The transparency of the peer-review process can be seen as an indicator of peer-review quality allowing the tool to be used to predict academic quality in new journals.

Excise taxes were only partially passed onto consumers (after adjustment, $1 tax associated with $0.90 increase in price, p < 0.0001) and the pass-through was slightly higher in areas that had bans but did not differ by area-level socio-demographics. Bans were associated with a slight increase in cigarette price (after adjustment, $0.09 per-pack, p < 0.0001). Taxes and bans were associated with reduction in smoking prevalence and taxes had a stronger association when combined with bans, suggesting a synergistic effect. Given wide variation in store-level prices, and uneven state/county implementation of taxes and bans, more federal policies should be considered.

    In the USA, little is known about local variation in retail cigarette prices; price variation explained by taxes, bans, and area-level socio-demographics, and whether taxes and hospitality bans have synergistic effects on smoking prevalence. Cigarette prices 2001–2011 from chain supermarkets and drug stores (n = 2973) were linked to state taxes (n = 41), state and county bar/restaurant smoking bans, and census block group socio-demographics. Hierarchical models explored effects of taxes and bans on retail cigarette prices as well as county smoking prevalence (daily, non-daily). There was wide variation in store-level cigarette prices in part due to differences in state excise taxes. Excise taxes were only partially passed onto consumers (after adjustment, $1 tax associated with $0.90 increase in price, p < 0.0001) and the pass-through was slightly higher in areas that had bans but did not differ by area-level socio-demographics.

    2012-01-01

    Every now and then, we observe a fierce price war in a real world market, through which competing firms end up with a Bertrand-like price competition equilibrium. Despite this, very little has been known in the existing literature as to why a price competition market is formed. We address this question in the context of a choice between engaging in price competition and holding a price leader. Focusing on a duopoly market, we demonstrate that if supply is tight relative to demand, and if the ...

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

  20. International price comparisons for pharmaceuticals. Measurement and policy issues.

    1998-01-01

    Cross-national price comparisons for pharmaceuticals are commonly used for two purposes. Comparisons based on a sample of products are used to draw conclusions about differences in average price levels. Cross-national comparisons applied to individual products are also used by governments to set domestic prices. This paper examines the major methodological issues raised by international price comparisons, focusing on measurement of differences in average price levels and the validity of policy conclusions drawn from such price comparison studies. It argues that valid measures of average price levels can only be obtained from comparisons based on a comprehensive or representative sample of products, appropriately weighted, following standard index number methods. Comparisons of individual product prices should take into account the manufacturer's entire product portfolio over time rather than focus narrowly on a single product at a point in time. Because of the great variation across countries in both the range of drug compounds available and the dosage forms, strengths and pack sizes for each compound, obtaining a broadly comprehensive or representative sample is problematical. If products are required to match on all dimensions, including molecule, manufacturer, strength and pack, as is common in most international price comparisons, then only a very small and unrepresentative sample of the drugs available in each country can be included in the analysis. A trade-off between the desire to compare only identical products and the need to compare a truly representative sample of a country's pharmaceutical market is therefore necessary. A valid comparison of average drug prices should include generics and over-the-counter products that are good substitutes for branded prescription drugs, with all forms, strengths and packs. To achieve this broad representation, however, the requirements of same manufacturer, same brand, dosage form, strength and pack size must be

    Full Text Available The literature on agricultural commodity price volatility in Nigeria has constantly reflected that an excessive price movement is harmful for both producers and consumers, particularly for those who are not able to cope with that new source of economic uncertainty. It has also raised an extensive debate on the main determinants behind the large agricultural commodity price swings observed in the last years without recourse for the price generating process. To narrow this gap, the study examined the price generating process and volatility in the Nigerian agricultural commodities market using secondary data for price series on meat, cereals, sugar, dairy and aggregate food for the period of January 1990 to February 2014. The data were analysed using the linear Gaussian State-Space (SS model. The results of the descriptive statistics showed that the coefficients of variation for cereals (39.88%, food (32.65% and dairy price (43.08% were respectively higher during the overall time period (January 1990 to February 2014 than during the first (January 1990 to January 2002 and second (February 2002 to February 2014 sub-time periods. The results of the inferential statistics showed that authoregressive moving average (ARMA model is the most selected Nigeria agricultural commodity price generating model for the time periods, that a unit increase in the past price state of cereals, dairy, sugar, meat and aggregate food would increase the future price of sugar, meat and aggregate food by N0.14, N0.28 and N0.15 respectively but decrease future price of cereals and dairy by about N1.00 and N0.21 respectively, and that the one-step ahead predicted value for the first out-ofsample period for cereals, meat, dairy and sugar price were 6317.86, 10.24 and 2.06 respectively. The Nigerian agricultural commodity prices have experienced high variability over the period, and such volatility, price-generating process and the determinants of the Nigerian food commodities

    External reference pricing (ERP) is a price regulation tool widely used by policy makers in the European Union (EU) Member States (MS) to contain drug cost, although in theory, it may contribute to modulate prices up and down. The objective of this article was to summarise and discuss the main findings of part of a large project conducted for the European Commission ('External reference pricing of medicinal products: simulation-based considerations for cross-country coordination'; see www.ec.europa.eu/health/healthcare/docs/erp_reimbursement_medicinal_products_en.pdf) that aimed to provide an overview of ERP systems, both on processes and potential issues in 31 European countries (28 EU MS, Iceland, Norway, and Switzerland). A systematic structured literature review was conducted to identify and characterise the use of ERP in the selected countries, to describe its impact on the prices of pharmaceuticals, and to discuss the possible cross-country coordination issues in EU MS. This research was complemented with a consultation of competent authorities' and international organisations' representatives to address the main issues or uncertainties identified through the literature review. All selected countries applied ERP, except the United Kingdom and Sweden. Twenty-three countries used ERP as the main systematic criterion for pricing. In the majority of European countries, ERP was based on legislated pricing rules with different levels of accuracy. ERP was applied either for all marketed drugs or for specific categories of medicines; it was mainly used for publicly reimbursed medicines. The number of reference countries included in the basket varied from 1 to 31. There was a great variation in the calculation methods used to compute the price; 15 countries used the average price, 7 countries used the lowest price, and 7 countries used other calculation methods. Reported limitations of ERP application included the lack of reliable sources of price information, price

    The recent surge in oil prices rakes up old fears and the spectre of stagflation hangs over worldwide economic growth's forecasts. After 30 years of research however analysts still disagree about the influence of oil prices on macro-economic variations and the estimations of the consequences of a costlier barrel differ. As to the United States for example, elasticities between real GDP and oil price form a wide spectrum stretching from a value close to -1% to -11,6%. In this context, we try to identify the potential sources of instability in the oil price-macro-economy relationship in order to explain the width of this range. First we draw attention to the distinction between the effects of an upward disequilibrium and of an upturn in the equilibrium in the oil price series. This distinction lets us share the range of published results in two parts: the elasticities of real American GDP with respect to an upward imbalance and with respect to a rise in the equilibrium price would lie approximately in the ranges extending, respectively, from -1% to -5,5% and from -5% to -11,6%. We direct our work towards the analysis of the consequences of short-run variations in the oil prices on the U.S. business cycle. We identify a set of influences which condition the vulnerability of an economy and then construct an econometric sectoral and non-linear model inspired from Marshall's theory. The simulations conducted let us explain the long-run weakening in the oil price-macro-economy relationship and highlight the prominent part played by imported inflation and monetary policy in the crisis of the 70's and 80's. According to the values of the structural factors in the model and to the shape of the oil price short-run disequilibrium, the elasticities evaluated cover the whole range of published elasticities.

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

  5. Price floors for emissions trading

    2011-01-01

    Price floors in greenhouse gas emissions trading schemes can guarantee minimum abatement efforts if prices are lower than expected, and they can help manage cost uncertainty, possibly as complements to price ceilings. Provisions for price floors are found in several recent legislative proposals for emissions trading. Implementation however has potential pitfalls. Possible mechanisms are government commitments to buy back permits, a reserve price at auction, or an extra fee or tax on acquittal of emissions permits. Our analysis of these alternatives shows that the fee approach has budgetary advantages and is more compatible with international permit trading than the alternatives. It can also be used to implement more general hybrid approaches to emissions pricing. - Research highlights: → Price floors for emissions trading schemes guarantee a minimum carbon price. → Price floors mean that emissions can be less than specified by the ETS cap. → We examine how price floors can relate to different policy objectives. → We compare different mechanisms for implementing a price floor. → We find that a mechanism where there is an extra tax or fee has advantages.

  6. Trading network predicts stock price.

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

    Ólafsson, Tjörvi; Pétursdóttir, Ásgerdur; Vignisdóttir, Karen Á.

    This price setting survey among Icelandic firms aims to make two contributions to the literature. First, it studies price setting in an advanced economy within a more turbulent macroeconomic environment than has previously been done. The results indicate that price adjustments are to a larger...... extent driven by exchange rate fluctuations than in most other advanced countries. The median Icelandic firm reviews its prices every four months and changes them every six months. The main sources of price rigidity and the most commonly used price setting methods are the same as in most other countries....... A second contribution to the literature is our analysis of the nexus between price setting and exchange rate movements, a topic that has attracted surprisingly limited attention in this survey-based literature. A novel aspect of our approach is to base our analysis on a categorisation of firms...

    2009-11-15

    Bernanke [Bernanke, Ben S. Irreversibility, uncertainty, and cyclical investment. Quarterly Journal of Economics 98 (1983), 85-106.] shows how uncertainty about energy prices may induce optimizing firms to postpone investment decisions, thereby leading to a decline in aggregate output. Elder and Serletis [Elder, John and Serletis, Apostolos. Oil price uncertainty.] find empirical evidence that uncertainty about oil prices has tended to depress investment in the United States. In this paper we assess the robustness of these results by investigating the effects of oil price uncertainty in Canada. Our results are remarkably similar to existing results for the United States, providing additional evidence that uncertainty about oil prices may provide another explanation for why the sharp oil price declines of 1985 failed to produce rapid output growth. Impulse-response analysis suggests that uncertainty about oil prices may tend to reinforce the negative response of output to positive oil shocks. (author)

    2013-01-01

    In this paper we study an optimal portfolio selection problem under instantaneous price impact. Based on some empirical analysis in the literature, we model such impact as a concave function of the trading size when the trading size is small. The price impact can be thought of as either a liquidity cost or a transaction cost, but the concavity nature of the cost leads to some fundamental difference from those in the existing literature. We show that the problem can be reduced to an impulse control problem, but without fixed cost, and that the value function is a viscosity solution to a special type of Quasi-Variational Inequality (QVI). We also prove directly (without using the solution to the QVI) that the optimal strategy exists and more importantly, despite the absence of a fixed cost, it is still in a “piecewise constant” form, reflecting a more practical perspective.

    2012-06-01

    An empirical research on Chinese stock markets is conducted using statistical tools. First, the multifractality of stock price return series, ri(ri=ln(Pt+1)-ln(Pt)) and trading volume variation series, vi(vi=ln(Vt+1)-ln(Vt)) is confirmed using multifractal detrended fluctuation analysis. Furthermore, a multifractal detrended cross-correlation analysis between stock price return and trading volume variation in Chinese stock markets is also conducted. It is shown that the cross relationship between them is also found to be multifractal. Second, the cross-correlation between stock price Pi and trading volume Vi is empirically studied using cross-correlation function and detrended cross-correlation analysis. It is found that both Shanghai stock market and Shenzhen stock market show pronounced long-range cross-correlations between stock price and trading volume. Third, a composite index R based on price and trading volume is introduced. Compared with stock price return series ri and trading volume variation series vi, R variation series not only remain the characteristics of original series but also demonstrate the relative correlation between stock price and trading volume. Finally, we analyze the multifractal characteristics of R variation series before and after three financial events in China (namely, Price Limits, Reform of Non-tradable Shares and financial crisis in 2008) in the whole period of sample to study the changes of stock market fluctuation and financial risk. It is found that the empirical results verified the validity of R.

    Medicine price information mechanisms provide an essential tool to countries that seek a better understanding of product availability, market prices and price compositions of individual medicines. To be effective and contribute to cost savings, these mechanisms need to consider prices in their particular contexts when comparing between countries. This article discusses in what ways medicine price information mechanisms can contribute to increased price transparency and how this may affect access to medicines for developing countries. We used data collected during the course of a WHO project focusing on the development of a vaccine price and procurement information mechanism. The project collected information from six medicine price information mechanisms and interviewed data managers and technical experts on key aspects as well as observed market effects of these mechanisms.The reviewed mechanisms were broken down into categories including objective and target audience, as well as the sources, types and volumes of data included. Information provided by the mechanisms was reviewed according to data available on medicine prices, product characteristics, and procurement modalities. We found indications of positive effects on access to medicines resulting from the utilization of the reviewed mechanisms. These include the uptake of higher quality medicines, more favorable results from contract negotiations, changes in national pricing policies, and the decrease of prices in certain segments for countries participating in or deriving data from the various mechanisms. The reviewed mechanisms avoid the methodological challenges observed for medicine price comparisons that only use national price databases. They work with high quality data and display prices in the appropriate context of procurement modalities as well as the peculiarities of purchasing countries. Medicine price information mechanisms respond to the need for increased medicine price transparency and have the

    2017-11-01

    Full Text Available Ex-vessel fish prices are essential for comprehensive fisheries management and socioeconomic analyses for fisheries science. In this paper, we reconstructed a global ex-vessel price database with the following areas of improvement: (1 compiling reported prices explicitly listed as “for reduction to fishmeal and fish oil” to estimate prices separately for catches destined for fishmeal and fish oil production, and other non-direct human consumption purposes; (2 including 95% confidence limit estimates for each price estimation; and (3 increasing the number of input data and the number of price estimates to match the reconstructed Sea Around Us catch database. Our primary focus was to address this first area of improvement as ex-vessel prices for catches destined for non-direct human consumption purposes were substantially overestimated, notably in countries with large reduction fisheries. For example in Peru, 2010 landed values were estimated as 3.8 billion real 2010 USD when using separate prices for reduction fisheries, compared with 5.8 billion using previous methods with only one price for all end-products. This update of the price database has significant global and country-specific impacts on fisheries price and landed value trends over time.

  16. Pricing and tariffs

    International Nuclear Information System (INIS)

    Dyrelund, A.

    1993-01-01

    Danish suppliers of electricity and district heating are with a few exceptions either public utilities or cooperatives owned by consumers. The basic tariff regulations for electricity and heat in Denmark state that the tariff has to cover all costs and that only a reasonable interest of invested capital may be included in the tariff. Consequently, all profit has to be used to lower prices. For municipality-owned utilities the consumer prices would be the same if the consumers were the owners. It is typical for the district heating and electricity sector that the technical system, the organizations involved and the tariff levels show the same structure: Plants - transmission - distribution - consumer. E.g. the price of energy from the transmission system includes costs of plants and transmission, but not costs of distribution. Concerning energy saving measures in buildings it is important to note that energy saving measures should not be evaluated on the basis of saved GJ (Giga Joule) thermal energy and GJ electricity because the fuel energy consumption and the share of variable costs depend on the supply system. To find least-cost solutions to satisfy the basic demand for energy services, it is necessary to be aware of the whole chain of elements from fuel to services: fuel - plant - network - consumer installations - building envelope - services. The consumer tariff is the most important link between the supply systems and the buildings. A reasonably designed incentive tariff may work for least-cost solutions, whereas other tariffs may encourage a waste of resources, either waste of fuel energy or waste of investments. (AB)

    In this paper author deals with the regulation of electricity prices in the Slovak Republic. Author contests the social policy of the government through doped prices of electricity. Two thirds of electricity is generated in nuclear power plants in Slovakia. Hence, it is necessary to focus on the solution of problem of nuclear waste. In 2004 Ministry of Economy stated, that the deficit in nuclear fund, from which the country have to fully cover the costs of liquidation and final disposal of nuclear waste, is estimated in the amount of around 89 billion Slovak crowns (≅ 3.7 billion $). From it, so called historical deficit, which originated because of late foundation of fund, represents officially 15 billion Slovak crowns (≅ 0.62 billion $). In Slovakia exists the real risk, that by maintenance of present state by creation and draw of the fund, it will be possible to ensure only 39 per cent of financial sources necessary for full financial handling of the back part of nuclear energetic. Even though the Ministry of Economy in connection with privatisation of Slovenske elektrarne designed to decrease the transfers of operators of nuclear power plants into nuclear fund. In 2006 the Parliament decreased by the law the level of gains of the fund from sale of nuclear electricity (the second from two components of the gains of the fund) from 6.8 to 5.95 per cent from annual revenues. So the tax of forced reduction of the price of nuclear electricity will be represented by loading of the further generations

    2017-09-01

    Little is known about the price sensitivity of demand for home care of the disabled elderly. We partially fill this knowledge gap by using administrative data on the beneficiaries of the main French home care subsidy program in a department and exploiting interindividual variation in provider prices. We address the potential endogeneity of prices by taking advantage of the unequal spatial coverage of providers and instrumenting price by the number of municipalities served by a provider. We estimate a price elasticity of around -0.4 that is significantly different from both 0 and -1. This less than proportionate response of consumption to price has implications for the efficiency and redistributive impact of variation in the level of copayments in home care subsidy schemes.

    This paper reports estimates of the price elasticity of demand for heroin based on a newly constructed dataset. The dataset has two matched components concerning the same sample of regular heroin users: longitudinal information about real-world heroin demand (actual price and actual quantity at daily intervals for each heroin user in the sample) and experimental information about laboratory heroin demand (elicited by presenting the same heroin users with scenarios in a laboratory setting). Two empirical strategies are used to estimate the price elasticity of demand for heroin. The first strategy exploits the idiosyncratic variation in the price experienced by a heroin user over time that occurs in markets for illegal drugs. The second strategy exploits the experimentally induced variation in price experienced by a heroin user across experimental scenarios. Both empirical strategies result in the estimate that the conditional price elasticity of demand for heroin is approximately -0.80. Copyright © 2015 Elsevier B.V. All rights reserved.

    1990-01-01

    A fundamental premise of negotiated pricing as a demand-side management (DSM) tool is that price determines cost. As the ultimate objective of energy efficiency is to increase electromotive work while conserving resources, negotiated prices can have a significant impact as a DSM tool to force costs down. Three examples are offered of the effect of negotiated pricing as a DSM tool. The examples are a small hydroelectric company and an electric utility authority owned, a utility-to-customer example of negotiated pricing with the Public Service Company of Oklahoma's (PSO) system, and a large paper mill on PSO's system. Some of the major problems associated with negotiated pricing, outside of the human effort of finding and training knowledgeable and skilled negotiators, are: obtaining enough information about the customer or potential customer to be able to determine that in negotiating prices the utility is not giving away more benefits than the utility will gain; developing a pricing plan that fits both the customer's and utility's existing and potential future mode of operation; assuring that other customers who cannot negotiate on their own behalf are not adversely affected by utility revenue shortfalls; making such negotiated prices available to all similarly situated customers, so as not to inadvertently create unfair competitive advantages among them; and defining the shared benefits before and after the fact as a result of having negotiated prices in the first place

  2. Understanding gasoline pricing in Canada

    International Nuclear Information System (INIS)

    2001-04-01

    This brochure is designed to help consumers understand how gasoline is priced and explained why prices increase, fluctuate and vary by location, city or region. The price of a litre of gasoline reflects the costs of crude oil, refining, retailing and taxes. Taxes are usually the largest single component of gasoline prices, averaging 40 to 50 per cent of the pump price. The cost of crude oil makes up another 35 to 45 per cent of the price. Refining costs make up 10 to 15 per cent while the remaining 5 to 10 per cent represents retail costs. Gasoline retailers make a profit of about 1 cent per litre. The latest network technology allows national and regional retail chains to constantly monitor price fluctuations to change their prices at gasoline stations at a moments notice to keep up with the competition and to protect their market shares. Several government studies, plus the Conference Board of Canada, have reported that competition is working in favour of Canadian motorists. This brochure also explained the drawbacks of regulating crude and pump prices with the reminder that crude prices were regulated in the 1970s with many negative consequences. 2 tabs., 1 fig

  3. Transfer Pricing - An Innovative Approach

    Directory of Open Access Journals (Sweden)

    Ramona MAXIM

    2017-06-01

    Full Text Available This paper presents transfer pricing and elements of drafting the transfer pricing file by the big companies. The transfer pricing procedure was founded based upon Order no. 442/2016 and the Fiscal Procedure Code and it represents a method upon which the tax base is transferred from a high tax country to a country with low taxation. This legislation outlines the conditions which companies must observe in order to draft the transfer pricing documentation and the significance thresholds. The purpose to draft a transfer pricing file is to reduce the differences between prices and market value and the actual results of company taxation. Economic double taxation occurs when tax authorities apply price adjustments because the company did not respect the principle of market value. Keeping records of transfer pricing and practicing a price aligned to market requirements contribute to an understanding of business development and the creation of appropriate tax planning. Taking into account all these aspects and the fact that any taxpayer is tempted to pay the lowest possible fees, tax havens become an option. In this context we can speak of a tax haven as a loophole in the use of the market price.

    This chapter with 58 references reviews the modelling and empirical behaviour of volatility in energy prices. Constant volatility and stochastic volatility are discussed. Markovian models of stochastic volatility are described and the different classes of Markovian stochastic volatility model are examined including auto-regressive volatility, option implied and forecasted volatility, Garch volatility, Egarch volatility, multivariate Garch volatility, and stochastic volatility and dynamic hedging policies. Other volatility models and option hedging are considered. The performance of several stochastic volatility models as applied to heating oil, light oil, natural gas, electricity and light crude oil are compared

  7. PRICING STRATEGY FOR DIGITAL PRODUCTS

    Directory of Open Access Journals (Sweden)

    MARIA MAGDALENA CRIVEANU

    2018-02-01

    Full Text Available The current society imposes an alert pace on companies that need to adapt to change, become more flexible and adopt new strategies to maintain market share. Digital marketing is a useful tool for promoting products, as customers can access a range of product information at any time and from anywhere. At the same time, another advantage on the part of companies is the lower promotion costs as compared to traditional promotional methods, as well as the establishment of a connection and a communication bridge with each client. The most important component in the process of purchasing a product is inevitably the price. It communicates a series of information about the product and the customer so that the price can be an important element of persuasion in relation to other marketing strategies. Most of the time, the smallest price is the most important factor in making a decision about buying a product, and digital marketing offers the posibility to compare prices. In this sense, digital marketing can provide both an advantage and a disadvantage for traders, as the small price may invalidate other marketing strategies or product features. In this sense, pricing is a challenge for marketing departments because the pricing strategy is deferring from the sterile formula of pricing which meant covering costs and making profit. This paper aims to analyze the extent to which price is an important element in purchasing a product, as well as highlighting a variety of methods and techniques used in pricing. Quantitative research is based on a questionnaire applied to 100 respondents in order to identify the correct pricing strategy. Research results communicate an important message to merchants who have to adjust the price of each buyer individually, so that the buyer profile is particularly important in setting the price.

  8. Price sensitive demand with random sales price - a newsboy problem

    Science.gov (United States)

    Sankar Sana, Shib

    2012-03-01

    Up to now, many newsboy problems have been considered in the stochastic inventory literature. Some assume that stochastic demand is independent of selling price (p) and others consider the demand as a function of stochastic shock factor and deterministic sales price. This article introduces a price-dependent demand with stochastic selling price into the classical Newsboy problem. The proposed model analyses the expected average profit for a general distribution function of p and obtains an optimal order size. Finally, the model is discussed for various appropriate distribution functions of p and illustrated with numerical examples.

  9. Modelling the impact of oil prices on Vietnam's stock prices

    Narayan, Paresh Kumar; Narayan, Seema

    2010-01-01

    The goal of this paper is to model the impact of oil prices on Vietnam's stock prices. We use daily data for the period 2000-2008 and include the nominal exchange rate as an additional determinant of stock prices. We find that stock prices, oil prices and nominal exchange rates are cointegrated, and oil prices have a positive and statistically significant impact on stock prices. This result is inconsistent with theoretical expectations. The growth of the Vietnamese stock market was accompanied by rising oil prices. However, the boom of the stock market was marked by increasing foreign portfolio investment inflows which are estimated to have doubled from US$0.9 billion in 2005 to US$1.9 billion in 2006. There was also a change in preferences from holding foreign currencies and domestic bank deposits to stocks local market participants, and there was a rise in leveraged investment in stock as well as investments on behalf of relatives living abroad. It seems that the impact of these internal and domestic factors were more dominant than the oil price rise on the Vietnamese stock market. (author)

  10. The outlook for oil prices in 1992 - results of a survey

    International Nuclear Information System (INIS)

    Hawdon, D.

    1992-01-01

    The eighth in a series of oil price expectation studies took place on 18th March 1992 at the Prospects for Oil Prices conference held at the University of Surrey. Thirty-one participants returned a questionnaire designed to elicit 12 month ahead and 5 year ahead price expectations. Respondents were asked to indicate their view of the likely price of oil in certain broad price ranges. These were selected to cover the wide variation of prices experienced since the early 1970s. The results show the 12 month's ahead expectations all clustered in the range $10 to $25 per barrel and $16-$20 as the median predicted price. In comparison with the 1991 expectations, a much higher proportion of respondents (77.4 as compared to 50% in 1991) gave $16-20 as their expected price range, whilst fewer expected prices to rise (19% compared with 46% in 1991). The stability of the 12 month ahead price expectations is a remarkable feature of a period which has witnessed much tension in the Middle East and in the former Soviet Union. This stability extends to the 5 year ahead forecasts as well. Here the median expectation is for prices to rise to the $21-25 per barrel range in money of the day terms though there is evidence of a growing scepticism about the oil market's ability to sustain higher prices in the long run.

  11. Pricing hazardous substance emissions

    Staring, Knut; Vennemo, Haakon

    1998-12-31

    This report discusses pricing of emissions to air of several harmful substances. It combines ranking indices for environmentally harmful substances with economic valuation data to yield price estimates. The ranking methods are discussed and a relative index established. Given the relative ranking of the substances, they all become valued by assigning a value to one of them, the `anchor` substance, for which lead is selected. Valuations are provided for 19 hazardous substances that are often subject to environmental regulations. They include dioxins, TBT, etc. The study concludes with a discussion of other categories of substances as well as uncertainties and possible refinements. When the valuations are related to CO, NOx, SOx and PM 10, the index system undervalues these pollutants as compared to other studies. The scope is limited to the outdoor environment and does not include global warming and eutrophication. The indices are based on toxicity and so do not apply to CO{sub 2} or other substances that are biologically harmless. The index values are not necessarily valid for all countries and should be considered as preliminary. 18 refs., 6 tabs.

    It looks like that all over the World things are changing. Many countries, Spain among them, where electricity regulations were usual, are changing their regulatory mainframe. Since January 1, 1998, electricity production is a deregulated activity in Spain. There has to be open market competition. Prices that are very important for the time coming, have to cover the production cost plus some profits in order to maintain the company profitability. This cultural change applies to all our production facilities, including nuclear power plants. Taking into account this new situation and the nuclear competitiveness, it is important for all of us to understand this issue. As it is well known, nuclear energy is capital intensive, that means it has to compete as base load units due to their low operating costs and their large capital ones. For that reason it is important to reduce as much as possible the operating and maintenance cost as well as the fuel one, which will allow nuclear plants to compete in marginal costs with others units. Nuclear energy, in Spain, is not going to fix the pool price but it has to recover some depreciation through it, the remaining being recovered by the recognition of an important part of the stranded cost.

    Palm oil price fluctuated without any clear trend or cyclical pattern in the last few decades. The instability of food commodities price causes it to change rapidly over time. This paper attempts to develop Autoregressive Distributed Lag (ARDL) model in modeling and forecasting the price of palm oil. In order to use ARDL as a forecasting model, this paper modifies the data structure where we only consider lagged explanatory variables to explain the variation in palm oil price. We then compare the performance of this ARDL model with a benchmark model namely ARIMA in term of their comparative forecasting accuracy. This paper also utilize ARDL bound testing approach to co-integration in examining the short run and long run relationship between palm oil price and its determinant; production, stock, and price of soybean as the substitute of palm oil and price of crude oil. The comparative forecasting accuracy suggests that ARDL model has a better forecasting accuracy compared to ARIMA.

  17. A Multiperiod Equilibrium Pricing Model

    Directory of Open Access Journals (Sweden)

    Minsuk Kwak

    2014-01-01

    Full Text Available We propose an equilibrium pricing model in a dynamic multiperiod stochastic framework with uncertain income. There are one tradable risky asset (stock/commodity, one nontradable underlying (temperature, and also a contingent claim (weather derivative written on the tradable risky asset and the nontradable underlying in the market. The price of the contingent claim is priced in equilibrium by optimal strategies of representative agent and market clearing condition. The risk preferences are of exponential type with a stochastic coefficient of risk aversion. Both subgame perfect strategy and naive strategy are considered and the corresponding equilibrium prices are derived. From the numerical result we examine how the equilibrium prices vary in response to changes in model parameters and highlight the importance of our equilibrium pricing principle.

  18. The price of crude oil

    International Nuclear Information System (INIS)

    Bakhtiari, A.M.S.

    1999-01-01

    The price of crude oil is among the most important prices quoted daily across the world - which is not surprising, since crude oil is the most widely used source of energy worldwide, as well as being a unique commodity. When petroleum burst onto the world stage in 1859, its price first went through some initial gyrations (1860-70), before settling in the $1.00 - 2.00 per barrel range (barring a few exceptions) for a full century. Then, the price underwent two 'shocks' (1973 and 1980), followed by the 'counter-shock' of 1986. Thereafter, the price entered the relative stability of the $15 - 20 /b consensus, where it lingered until recently. Some day, there is bound to be a fresh paradigm of 'insufficient oil reserves', thus ushering in a new era for oil prices. Taking into consideration available data on reserves and expert analysis, it would seem that that day may be years rather than decades away

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

    Since price is both a key determinant of smoking and one of the few remaining marketing strategies available in countries without point-of-sale tobacco display, this study examines cigarette price variations in the Australian market and assesses whether those variations are consistent with price being used to increase or maintain smoking among price-sensitive groups. An audit of 1739 tobacco retailers was used to collect variations in the price of the best-selling Australian cigarette brand, as well as record retailer compliance with tobacco retailing legislation. We examined variation in pricing across outlet type, demographic variations (socioeconomic level, % in the area under 18 and % born in Australia), remoteness and retailer compliance with tobacco retailing legislation. Multipacks were offered by 27.8% of retailers, with the average pack price in a twin pack $1.32 (or 7.3%) cheaper than a single pack. Prices were significantly lower in some outlet types, in lower socioeconomic postcodes and in those with a higher percentage of people under 18. In contrast with other consumer goods, prices were lower (although not significantly so) outside major cities. The provision of substantial multi-pack discounts and lower prices in postcodes with a higher proportion of price-sensitive smokers (young people and those from lower socioeconomic groups) is consistent with targeted discounts being used as a tobacco marketing strategy. The results support policy interventions to counter selective discounts and to require disclosure of trade-based discounts. Published by the BMJ Publishing Group Limited.

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

    Is there a link between the stock market and business investment? Empirical evidence indicates that there is. A firm tends to invest more when its stock price increases, and it tends to invest less when the price falls. In “Stock Prices and Business Investment,” Yaron Leitner discusses existing research that explains this relationship. One question under consideration is whether the stock market actually improves investment decisions.

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

    Price stabilization is an important policy goal of government intervention in competitive markets. These policies are primarily directed at raising producer income and stabilizing market prices at levels acceptable to consumers and producers (Fox 1956, Turnovsky 1978, Newbery and Stiglitz 1979). Many of the stabilization policy results have been developed from the study of agricultural commodity markets. In these markets, prices tend to be highly variable due to uncertain and inelastic supply...

    We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but often lower consumer surplus, than linear pricing. By contrast, in a unit-demand model where consumers may buy one product from one firm and another product from another firm, bundling generally acts to reduce profit and welfare and to boost cons...

I show that pricing at pricing points in different currencies may contribute to explaining deviations from the law of one price. Observing strictly equal prices is more probable if prices are set at psychological and fractional pricing points in a common currency. The latter is also found to reduce the size of price deviations. Additionally, price differences increase as transaction c...

    2001-01-01

    This PowerPoint presentation included 36 slides that described the state of oil prices and how to predict them. Prices are random, stochastic, chaotic, mean-reverting and driven by speculators, oil companies and OPEC. The many factors that enable price forecasting are economic growth, weather, industry behaviour, speculators, OPEC policy choices, Mexico/Russia production policy, non-OPEC supply and the interpretation of the above factors by OPEC, speculators, traders and the petroleum industry. Several graphs were included depicting such things as WTI price forecasts, differentials, oil market change in 2001, inventory levels, and WTI backwardation. The presentation provided some explanations for price uncertainties, price surges and collapses. U.S. GDP growth and the volatility of Iraq's production was also depicted. The author predicted that economic growth will occur and that oil demand will go up. Oil prices will fluctuate as the Middle East will be politically unstable and weather will be a major factor that will influence oil prices. The prices are likely to be more volatile than in the 1986 to 1995 period. 2 tabs., 22 figs

    Full Text Available We analyze a novel alpha momentum strategy that invests in stocks based on three-factor alphas which we estimate using daily returns. The empirical analysis for the U.S. and for Europe shows that (i past alpha has power in predicting the cross-section of stock returns; (ii alpha momentum exhibits less dynamic factor exposures than price momentum and (iii alpha momentum dominates price momentum only in the U.S. Connecting both strategies to behavioral explanations, alpha momentum is more related to an underreaction to firm-specific news while price momentum is primarily driven by price overshooting due to momentum trading.

    1997-01-01

    This paper introduces a new pricing system - based on the Chilean tariff regulations - to deal with an uncertain energy supply. It consists of a basic rate for each unit actually consumed and a compensation that the utilities pay their customers for each unit of energy that they voluntarily reduce below their normal consumption during an energy shortage. Within the framework of a model that portrays the stylized facts of the Chilean electric system, and assumes risk-neutral agents, this paper shows the equivalency of the new pricing system with both contingent pricing and priority pricing.

    Uranium producers came alive in August, helping spot prices crack the $8.00 barrier for the first time since March. The upper end of NUKEM's price range actually finished the month at $8.20. Scrambling to fulfill their long-term delivery contracts, producers dominate the market. In the span of three weeks, five producers came out for 2 million lbs U3O8, ultimately buying nearly 1.5 million lbs. One producer accounted for over half this volume. The major factor behind rising prices was that producers required specific origins to meet contract obligations. Buyers willing to accept open origins created the lower end of NUKEM's price range

Furthermore, I document that the aggregate house price loss of 2.1 billion DKK greatly exceeds the increase in public debt of 1 billion DKK. I find that the drop in house prices is sustained 1 year, indicating that the housing market initially overreacts...

  15. The determinants of oil prices

    Angelier, J-P.

    1991-01-01

    In recent years, swings in oil prices have been of unprecendented severity and frequency. Three factors work together to determine the price of oil: in the short term, the balance between supply and demand; in the medium term, the structure of the oil industry; and in the long term, the marginal production cost consistent with world oil demand. An oil price forecast is presented based on these considerations, and it is predicted that in the year 2000, oil prices will not be significantly different from those of today. 28 refs

  16. Price Strategies in Banking Marketing

    Full Text Available All organizations must settle a price for the services they offer. The price for services is an important element of the marketing mix, being an important income source for the organization. The settlement of a correct price, both for the market and the competition, is a significant element for the sector of financial - banking services. Another important factor to take into consideration is the fact that the banks do not settle only the prices for individual services, but also coordinate their prices for service packages. As the competition in the financial - banking services has intensified, the settlement of correct prices has become an essential element for the marketing strategy. Nevertheless it is important to remind that the price is not a central element. There are other significant grounds, the price being only one of the elements of the marketing mix. Although in Romania many customers may be sensitive in present to the price, as the competition will increase, the quality of the services will become more important to the customers, and the demand will be complex.

  17. Is Swedish district heating operating on an integrated market? – Differences in pricing, price convergence, and marketing strategy between public and private district heating companies

    International Nuclear Information System (INIS)

    Åberg, M.; Fälting, L.; Forssell, A.

    2016-01-01

    The deregulation of the Swedish electricity market in 1996 made it possible to operate municipal district heating commercially. Until that time district heating had been organized mainly as municipal utilities. After 1996 district heating is instead expected to function on a market. In competitive and integrated markets, prices are expected to be equal, or converging. To find out if district heating operates on an integrated market the differences in price levels, price convergence, price strategy, and business goals, among municipal, private and state owned district heating companies are investigated. Price statistics was used along with results from a questionnaire that was answered by representatives for 109 Swedish district heating companies. The results show that prices among district heating systems do not converge significantly and that variations in prices among municipal systems are larger than among private and state owned systems. Furthermore, despite the fact that district heating is supposed to be commercial, a vast majority of district heating companies apply cost-based pricing and not market pricing. The municipal companies give priority to political goals before financial goals. The conclusion is that a Swedish integrated market for heat has not yet evolved, and some district heating price-controlling mechanism is necessary. - Highlights: • Price statistics and owner type data were used along with results from a questionnaire. • Results show that prices among district heating systems do not converge. • Municipal district heating companies still apply cost-based pricing to a large extent. • District heating companies are not operating on an integrated market for heat. • Some price-controlling mechanism for district heating is necessary.

    Price level and price transparency are input to shippers’ choice of supply chain and transport mode. In this paper, we analyse current port pricing structures in the light of the pricing literature and consider opportunities for improvement. We present a detailed overview of pricing criteria, who sets prices and who ultimately foots the bill for port-of-call charges, cargo-handling fees and congestion charges. Current port pricing practice is based on a rather linear structure and fails to in...

    2011-12-01

    To study differences in the role of price and value in food choice between low-income and higher-income consumers and to study the perception of consumers about pricing strategies that are of relevance during grocery shopping. A cross-sectional study was conducted using structured, written questionnaires. Food choice motives as well as price perceptions and opinion on pricing strategies were measured. The study was carried out in point-of-purchase settings, i.e. supermarkets, fast-food restaurants and sports canteens. Adults (n 159) visiting a point-of-purchase setting were included. Price is an important factor in food choice, especially for low-income consumers. Low-income consumers were significantly more conscious of value and price than higher-income consumers. The most attractive strategies, according to the consumers, were discounting healthy food more often and applying a lower VAT (Value Added Tax) rate on healthy food. Low-income consumers differ in their preferences for pricing strategies. Since price is more important for low-income consumers we recommend mainly focusing on their preferences and needs.

    The high price for oil and the decreased value of the Euro increase the risks for the stability of prices. Still, the prospects for inflation are favorable for the Euro zone. Less favorable are the consequences for the Netherlands, while the inflation difference with the Euro zone appears to become bigger, in particular as a result of the new Tax regulations in the Netherlands

    2009-01-01

    This paper proposes an overview and a prospective glance on the oil barrel price. It indicates the relevant indicators: Brent quotation, euro/dollar parity, economic activity indicators, world oil consumption distribution, crude oil production, refining capacity. It briefly presents the involved stake holders: crude oil producers, oil refiners, refined product dealers, and the OPEC. It discusses the major retrospective trends: evolution in relationship with geopolitical events and energy policies, strong correlation between oil demand and economic growth, prevalence of OPEC, growing importance of national oil companies. An emerging trend is noticed: growing role of emerging countries on the crude market. Some prospective issues are discussed: duration and intensity of economic recession, separation between economic growth and energy consumption, pace and ambition level of policies of struggle against climate change, exploitable resources, and geopolitical hazards. Four evolution hypotheses are discussed

  9. Airport Pricing Strategies

    Pels, Eric; Verhoef, Erik T.

    2003-01-01

    Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive congestion prices equal to the value of marginal travel delays a non-optimal response. This paper has developed a model of airport pricing that captures a number of these features. The model in particular reflects that airlines typically have market power and are engaged in oligopolistic competition at different sub-markets; that part of external travel delays that aircraft impose are internal to an operator and hence should not be accounted for in congestion tolls. We presented an analytical treatment for a simple bi-nodal symmetric network, which through the use of 'hyper-networks' would be readily applicable to dynamic problems (in discrete time) such as peak - off-peak differences, and some numerical exercises for the same symmetric network, which was only designed to illustrate the possible comparative static impacts of tolling, in addition to marginal equilibrium conditions as could be derived for the general model specification. Some main conclusions are that second-best optimal tolls are typically lower than what would be suggested by congestion costs alone and may even be negative, and that the toll as derived by Brueckner (2002) may not lead to an increase in total welfare. While Brueckner (2002) has made clear that congestion tolls on airports may be smaller than expected when congestion costs among aircraft are internal for a firm, our analysis adds to this that a further downward adjustment may be in order due to market power. The presence of market power (which causes prices to exceed marginal costs) may cause the pure congestion toll to be suboptimal, because the resulting decrease in demand is too high (the pure congestion tall does not take into account the decrease in consumer surplus). The various

  11. Transfer Pricing and FDI

    Patricia-Sabina Macelaru

    2013-08-01

    Full Text Available FDI analysis is usually performed within the frame of the win-win hypothesis. However, we believe that certain circumstances (MNEs following their own business objectives, lack of appropriate regulations, non-observance of the arm’s length principle may generate disproportionate advantages at the level of FDI stakeholders. The disequilibrium between reinvested profits and repatriated profits may be viewed as a proof of such disproportionate advantages of stakeholders involved in FDI. In addition to figures showing the comparison between reinvested and repatriated profits, as well as the way in which such indicators vary e.g. in case of abnormal business conditions (global economy collapse, we try to show that lack/misuse of transfer pricing regulations may generate even more disequilibrium, the MNEs using intra-group transactions as an additional way of repatriating non-taxable/low tax profits.

    The rationale for congestion charges is that by internalising the marginal external congestion cost, they restore efficiency in the transport market. In the canonical model underlying this view, congestion is a static phenomenon, users are taken to be homogenous, there is no travel time risk......, and a highly stylised model of congestion is used. The simple analysis also ignores that real pricing schemes are only rough approximations to ideal systems and that inefficiencies in related markets potentially affect the case for congestion charges. The canonical model tends to understate the marginal...... external congestion cost because it ignores user heterogeneity and trip timing inefficiencies. With respect to the relevance of interactions between congestion and congestion charges and tax distortions and distributional concerns, recent insights point out that there is no general case for modifying...

  13. Why fuel prices differ

    International Nuclear Information System (INIS)

    Rietveld, P.; Woudenberg, S. van

    2005-01-01

    Fuel taxes differ largely between countries. This paper reviews a number of considerations from the theory of public finance that may explain these differences. Based on a multiple regression model, we find for tax competition in Europe that small countries tend to be more aggressive than large countries by charging lower fuel taxes to attract customers from neighbouring countries. There is strong evidence that fuel is just considered as one of the many sources for government expenditure: as the share of government expenditure in GDP is higher, the fuel tax tends to be higher. No support is found for the hypothesis that fuel taxes are higher in countries where externality problems are more severe (proxied by car density of the country). In this respect, the normative literature on pricing externalities has found little support in the realities of transport policy. (author)

  14. The Pricing of natural gas

    International Nuclear Information System (INIS)

    Nese, Gjermund

    2004-11-01

    The report focuses on the pricing of natural gas. The motivation has been the wish of the Norwegian authorities to increase the use of natural gas and that this should follow market conditions. The pricing of gas occurs at present in various ways in the different markets. The report identifies to main factors behind the pricing. 1) The type of market i.e. how far the liberalization of the gas markets has gone in the various countries. 2) The development within the regulation, climate and tax policies. The gas markets are undergoing as the energy markets in general, a liberalization process where the traditional monopoly based market structures are replaced by markets based on competition. There are great differences in the liberalization development of the various countries, which is reflected in the various pricing principles applied for the trade of gas in the countries. The analysis shows that the net-back-pricing is predominant in some countries i.e. that the price is in various ways indexed towards and follow the development of the price of alternative energy carriers so that the gas may be able to compete. The development towards trade places for gas where the pricing is based on offer and demand is already underway. As the liberalization of the European gas markets progresses it is expected that the gas price will be determined increasingly at spot markets instead of through bilateral agreements between monopolistic corporations. The development within the regulation, climate and tax policies and to what extent this may influence the gas prices in the future, are also studied. There seem to be effects that may pull in both directions but it is evident that these political variables will influence the gas pricing in the international market to a large extent and thereby also the future internal natural gas market

  15. Pricing effects on food choices.

    Individual dietary choices are primarily influenced by such considerations as taste, cost, convenience and nutritional value of foods. The current obesity epidemic has been linked to excessive consumption of added sugars and fat, as well as to sedentary lifestyles. Fat and sugar provide dietary energy at very low cost. Food pricing and marketing practices are therefore an essential component of the eating environment. Recent studies have applied economic theories to changing dietary behavior. Price reduction strategies promote the choice of targeted foods by lowering their cost relative to alternative food choices. Two community-based intervention studies used price reductions to promote the increased purchase of targeted foods. The first study examined lower prices and point-of-purchase promotion on sales of lower fat vending machine snacks in 12 work sites and 12 secondary schools. Price reductions of 10%, 25% and 50% on lower fat snacks resulted in an increase in sales of 9%, 39% and 93%, respectively, compared with usual price conditions. The second study examined the impact of a 50% price reduction on fresh fruit and baby carrots in two secondary school cafeterias. Compared with usual price conditions, price reductions resulted in a four-fold increase in fresh fruit sales and a two-fold increase in baby carrot sales. Both studies demonstrate that price reductions are an effective strategy to increase the purchase of more healthful foods in community-based settings such as work sites and schools. Results were generalizable across various food types and populations. Reducing prices on healthful foods is a public health strategy that should be implemented through policy initiatives and industry collaborations.

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