Full Text Available This paper examines the long-run and short-run determinants of unleaded petrol price in Australia’s capitalcities using monthly data to find out whether prices respond asymmetrically to external shocks. Based on thecointegration test results and the estimated asymmetric short-run dynamic models, it is found that: (1 in thelong-run petrol prices are mainly determined by Tapis crude oil and Singapore petrol prices; (2 there issome evidence of asymmetric price adjustments in the short-run since petrol price increases have been mostlypassed on to the consumer faster than price decreases in four capital cities. More specifically, this paperprovides convincing evidence in support of asymmetric price adjustments and the “rockets-and-feathershypothesis” in Adelaide, Brisbane, Melbourne and Sydney. One can thus argue that there are a significantdegree of market inefficiency and/or collusion, requiring a closer government price monitoring and scrutiny.

A Simple Measure of Price Adjustment Coefficients.

OpenAIRE

Damodaran, Aswath

1993-01-01

One measure of market efficiency is the speed with which prices adjust to new information. The author develops a simple approach to estimating these price adjustment coefficients by using the information in return processes. This approach is used to estimate t he price adjustment coefficients for firms listed on the NYSE and the A MEX as well as for over-the-counter stocks. The author finds evidence of a lagged adjustment to new information in shorter return intervals for firms in all market ...

The optimal strategies in closed form are given under the decision scenarios with symmetric information; moreover, the first order conditions that the optimal retail price, optimal wholesale price, and optimal collection rate satisfy are given under the decision scenarios with asymmetric information......The optimal decision problem of a closed-loop supply chain with symmetric and asymmetric information structures is considered using game theory in this paper. The paper aims to explore how the manufacturer and the retailer make their own decisions about wholesale price, retail price, and collection...... rate under symmetric and asymmetric information conditions. Four game models are established, which allow one to examine the strategies of each firm and explore the role of the manufacturer and the retailer in four different game scenarios under symmetric and asymmetric information structures...

The asymmetric effect of coal price on the China's macro economy using NARDL model

Science.gov (United States)

Hou, J. C.; Yang, M. C.

2016-08-01

The present work endeavors to explore the asymmetric effect of coal price on the China's macro economy by applying nonlinear autoregressive distributed lag (NARDL) model for the period of January 2005 to June 2015. The obtained results indicate that the coal price has a strong asymmetric effect on China's macro economy in the long-run. Namely one percent increase in coal price leads to 0.6194 percent of the China's macro economy increase; and while the coal price is reduces by 1 percent, the China's macro economy will decrease by 0.008 percent. These data indicate that when coal price rises, the effect on China's macro economy is far greater than the price decline. In the short-run, coal price fluctuation has a positive effect on the China's macro economy.

The Asymmetric Effects of Oil Price Changes on the Economic Activities in Indonesia

Directory of Open Access Journals (Sweden)

Rina Juliet Artami

2018-01-01

Full Text Available This paper analyzes the asymmetric impact of oil price changes on the economic growth of and inflation in Indonesia by using the vector autoregression (VAR model for the period from 1990Q1 to 2016Q4. The results show that the impact of oil price changes on the gross domestic product (GDP is asymmetric, as a drop in oil prices decreases the GDP, whereas an increase in oil prices does not significantly affect GDP. It is crucial for Indonesia to reduce its dependency on oil, mainly as its primary source of revenue, and also consider utilizing more sources of renewable energy. At the same time, the effects of both the positive and negative changes in oil prices are found to be not statistically significant to inflation. The lack of impact of oil price changes on inflation can explain by the implementation of the fuel price subsidy in Indonesia.DOI: 10.15408/sjie.v7i1.6052

Exploring asymmetric behavior pattern from Indian oil products prices using NARDL and GHSOM approaches

International Nuclear Information System (INIS)

Chattopadhyay, Manojit; Kumar Mitra, Subrata

2015-01-01

The present work endeavors to explore the potential asymmetries in the pricing of oil products in India where prices are not only affected by the crude oil price changes in the international markets but are also subject to government interventions. In order to protect domestic consumers from this volatility, historically the government of India tried to control the domestic price of petroleum products by cross subsidization and giving subsidies. In this paper, we analyze the impact of crude oil price on domestic oil prices by applying nonlinear autoregressive distributed lag (NARDL) and Growing Hierarchical Self-Organizing Map (GHSOM) approaches for the period of April, 2005–July, 2014. The GHSOM has been explored through pattern analysis on the asymmetric behavior using similarity measures. From the study it can be interpreted that the prices of products left to be determined by the market exhibit a strong asymmetry. However, pricing of the products that are monitored and controlled by the government do not exhibit any such asymmetry. Hence, the question still remains – should the government intervene in pricing petroleum products when monopolistic attitudes of large oil companies are detrimental to the interest of retail consumers? - Highlights: • We explored the potential asymmetries in the pricing of oil products in India. • Analyze cointegration and asymmetric behavior of oil products by NARDL approach. • GHSOM method has been explored for pattern analysis on the asymmetric behavior. • The analysis reveals that the market determined prices exhibits a strong asymmetry. • Oil product pricing controlled by the government do not exhibit such asymmetry.

Economic analysis of coal price-electricity price adjustment in China based on the CGE model

International Nuclear Information System (INIS)

He, Y.X.; Zhang, S.L.; Yang, L.Y.; Wang, Y.J.; Wang, J.

2010-01-01

In recent years, coal price has risen rapidly, which has also brought a sharp increase in the expenditures of thermal power plants in China. Meantime, the power production price and power retail price have not been adjusted accordingly and a large number of thermal power plants have incurred losses. The power industry is a key industry in the national economy. As such, a thorough analysis and evaluation of the economic influence of the electricity price should be conducted before electricity price adjustment is carried out. This paper analyses the influence of coal price adjustment on the electric power industry, and the influence of electricity price adjustment on the macroeconomy in China based on computable general equilibrium models. The conclusions are as follows: (1) a coal price increase causes a rise in the cost of the electric power industry, but the influence gradually descends with increase in coal price; and (2) an electricity price increase has an adverse influence on the total output, Gross Domestic Product (GDP), and the Consumer Price Index (CPI). Electricity price increases have a contractionary effect on economic development and, consequently, electricity price policy making must consequently consider all factors to minimize their adverse influence.

Causes for an asymmetric relation between the price of crude oil and refined petroleum products

International Nuclear Information System (INIS)

Kaufmann, R.K.; Laskowski, C.

2005-01-01

We revisit the issue of asymmetries in the relation between the price of crude oil and refined petroleum products in the United States. An econometric analysis of monthly data indicates that the asymmetric relationship between the price of crude oil and motor gasoline is generated by refinery utilization rates and inventory behavior. The asymmetric relation between the price of crude oil and home heating oil probably is generated by contractual arrangements between retailers and consumers. Together, these results imply that price asymmetries may be generated by efficient markets. Under these conditions, there is little justification for policy interventions to reduce or eliminate price asymmetries in motor gasoline and home heating oil markets. (author)

A uniform price auction with locational price adjustments for competitive electricity markets

International Nuclear Information System (INIS)

Ethier, R.; Mount, T.; Schulze, W.; Zimmerman, R.; Thomas, R.

1999-01-01

Competitive electricity markets which rely on centralized dispatch require a mechanism to solicit offers from competing generators. Ideally, such an auction mechanism, provides incentives to submit offers equal to the marginal cost of generation for each generator. Economic theory suggests that the Uniform Price auction is an appropriate institution. However, an efficient implementation of this auction in an electricity context requires that the offers used in the auction reflect the appropriate locational price adjustments for transmission losses and congestion. This paper describes a uniform price auction that incorporates locational price adjustments on a Web-based platform suitable for experimentation. Preliminary results show dramatically different price and revenue results when compared with a simple continuous Discriminative auction. (author)

The asymmetric effects of oil price and monetary policy shocks. A nonlinear VAR approach

International Nuclear Information System (INIS)

Rahman, Sajjadur; Serletis, Apostolos

2010-01-01

In this paper we investigate the asymmetric effects of oil price shocks and monetary policy on macroeconomic activity, using monthly data for the United States, over the period from 1983:1 to 2008:12. In doing so, we use a logistic smooth transition vector autoregression (VAR), as detailed in Terasvirta and Anderson (1992) and Weise (1999), and make a distinction between two oil price volatility regimes (high and low), using the realized oil price volatility as a switching variable. We isolate the effects of oil price and monetary policy shocks and their asymmetry on output growth and, following Koop et al. (1996) and Weise (1999), we employ simulation methods to calculate Generalized Impulse Response Functions (GIRFs) to trace the effects of independent shocks on the conditional means of the variables. Our results suggest that in addition to the price of oil, oil price volatility has an impact on macroeconomic activity and that monetary policy is not only reinforcing the effects of oil price shocks on output, it is also contributing to the asymmetric response of output to oil price shocks.

ASYMMETRIC PRICE TRANSMISSION MODELING: THE IMPORTANCE OF MODEL COMPLEXITY AND THE PERFORMANCE OF THE SELECTION CRITERIA

Directory of Open Access Journals (Sweden)

Henry de-Graft Acquah

2013-01-01

Full Text Available Information Criteria provides an attractive basis for selecting the best model from a set of competing asymmetric price transmission models or theories. However, little is understood about the sensitivity of the model selection methods to model complexity. This study therefore fits competing asymmetric price transmission models that differ in complexity to simulated data and evaluates the ability of the model selection methods to recover the true model. The results of Monte Carlo experimentation suggest that in general BIC, CAIC and DIC were superior to AIC when the true data generating process was the standard error correction model, whereas AIC was more successful when the true model was the complex error correction model. It is also shown that the model selection methods performed better in large samples for a complex asymmetric data generating process than with a standard asymmetric data generating process. Except for complex models, AIC's performance did not make substantial gains in recovery rates as sample size increased. The research findings demonstrate the influence of model complexity in asymmetric price transmission model comparison and selection.

Retail fuel price adjustment in Germany: A threshold cointegration approach

International Nuclear Information System (INIS)

Asane-Otoo, Emmanuel; Schneider, Jan

2015-01-01

Consumers in Germany often complain that retail fuel prices usually adjust quickly to crude oil price increases than decreases and characterize this pricing pattern as market power exploitation. In this paper, we use both weekly national and daily city-specific (Berlin, Hamburg, Munich and Cologne) data to investigate the extent to which retail fuel prices in Germany adjust to changes in the international crude oil price. At the national level with weekly prices, we find positive asymmetries for both gasoline and diesel within the period 2003–2007, reflecting that retail prices react more swiftly to crude oil price increases than decreases. In contrast, for 2009–2013, we observe symmetric adjustment and negative asymmetry for retail diesel and gasoline prices, respectively. The city level analysis supports our findings in the latter time period. Thus, regulatory measures aimed at the retail fuel market over recent years seem to have been effective, and, contrary to consumers' perception, we find no evidence for excessive market power or collusion. - Highlights: • The paper examines the adjustment of German retail fuel (gasoline and diesel) prices to international crude oil price changes. • An error correction model with threshold cointegration is used to investigate the price dynamics. • The findings generally point to a competitive retail fuel pricing, notwithstanding the oligopolistic market structure

Price Changes, Resource Adjustments and Rational Expectations

Hoffmann, Kira

This study investigates the relationship between the accuracy of managerial demand expectations, resource adjustment decisions and selling price changes. In line with rational expectation theory, it is argued that managers adjust resources and selling prices differently in response to expected...... that cost elasticity is higher when a demand decrease is expected among companies with similar exposure to demand uncertainty. Overall, this implies that managerial competences in predicting future demand significantly determines firms’ profitability; especially when demand uncertainty is high...

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

Directory of Open Access Journals (Sweden)

Aghassi Mkrtchyan

2005-06-01

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

Price asymmetry in the Dutch retail gasoline market

International Nuclear Information System (INIS)

Bettendorf, L.; Van der Geest, S.A.; Varkevisser, M.

2002-01-01

This paper analyses retail price adjustments in the Dutch gasoline market. We estimate an asymmetric error correction model on weekly price changes for the years 1996 to 2001. We construct five datasets, one for each working day. The conclusions on asymmetric pricing are shown to differ over these datasets, suggesting that the choice of the day for which prices are observed matters more than commonly believed. In our view, the insufficient robustness of outcomes might explain the mixed conclusions found in the literature. Using two approaches, we also show that the effect of asymmetry on Dutch consumer costs is negligible

Oil production, oil prices, and macroeconomic adjustment under different wage assumptions

International Nuclear Information System (INIS)

Harvie, C.; Maleka, P.T.

1992-01-01

In a previous paper one of the authors developed a simple model to try to identify the possible macroeconomic adjustment processes arising in an economy experiencing a temporary period of oil production, under alternative wage adjustment assumptions, namely nominal and real wage rigidity. Certain assumptions were made regarding the characteristics of actual production, the permanent revenues generated from that oil production, and the net exports/imports of oil. The role of the price of oil, and possible changes in that price was essentially ignored. Here we attempt to incorporate the price of oil, as well as changes in that price, in conjunction with the production of oil, the objective being to identify the contribution which the price of oil, and changes in it, make to the adjustment process itself. The emphasis in this paper is not given to a mathematical derivation and analysis of the model's dynamics of adjustment or its comparative statics, but rather to the derivation of simulation results from the model, for a specific assumed case, using a numerical algorithm program, conducive to the type of theoretical framework utilized here. The results presented suggest that although the adjustment profiles of the macroeconomic variables of interest, for either wage adjustment assumption, remain fundamentally the same, the magnitude of these adjustments is increased. Hence to derive a more accurate picture of the dimensions of adjustment of these macroeconomic variables, it is essential to include the price of oil as well as changes in that price. (Author)

Is there an asymmetry in the response of diesel and petrol prices to crude oil price changes? Evidence from New Zealand

International Nuclear Information System (INIS)

Liu, Ming-Hua; Margaritis, Dimitris; Tourani-Rad, Alireza

2010-01-01

This paper examines how pre-tax petrol and diesel prices in New Zealand respond to changes in crude oil prices using an asymmetric error correction model. Our results show that oil companies adjust diesel prices upwards faster than they adjust them downwards, and the difference is statistically significant. However we find no statistical evidence for an asymmetry in the adjustment of petrol prices even though the magnitude of estimated coefficients suggests a faster response to rising prices. As diesel pricing is not as competitive as petrol pricing, calls for further government actions and monitoring of the oil market may be justified. Our findings also have important implications for the conduct of monetary policy as the pass-through of crude oil price changes can affect cost-push inflation. (author)

Deception and price in a market with asymmetric information

Directory of Open Access Journals (Sweden)

Kimmo Eriksson

2007-02-01

Full Text Available In markets with asymmetric information, only sellers have knowledge about the quality of goods. Sellers may of course make a declaration of the quality, but unless there are sanctions imposed on false declarations or reputations are at stake, such declarations are tantamount to cheap talk. Nonetheless, in an experimental study we find that most people make honest declarations, which is in line with recent findings that lies damaging another party are costly in terms of the liar's utility. Moreover, we find in this experimental market that deceptive sellers offer lower prices than honest sellers, which could possibly be explained by the same wish to limit the damage to the other party. However, when the recipient of the offer is a social tie we find no evidence for lower prices of deceptive offers, which seems to indicate that the rationale for the lower price in deceptive offers to strangers is in fact profit-seeking (by making the deal more attractive rather than moral.

2009-01-01

This paper analyses horizontal and vertical price dynamics in the EU petroleum markets. The results indicate that the cross-country price differentials have significant impact on the local price adjustments. We investigate the cross-national price spill-overs and find that the extent of the welfare transfer due to asymmetric price transmission, when analysed in a cross-country setting, is less pronounced than claimed in previous contributions in this area. We also find empirical evidence, although indirect, for the politically charged concept of 'fuel tourism', using a pan-European cross-product time series dataset. (author)

The Pricing Strategy of Oligopolistic Competition Food Firms with the Asymmetric Information and Scientific Uncertainty

Directory of Open Access Journals (Sweden)

Li Zhao

2017-01-01

Full Text Available The arguments for and against genetically modified (GM food focus on the characteristics of the scientific uncertainty and asymmetric information for the GM food. How do these two factors affect the competition and pricing strategy of food firms that separate GM food and conventional food conforming to consumer’s right to know? We explore the issue of pricing strategies between two firms producing horizontally and vertically differentiated foods in the context of asymmetric information and scientific uncertainty. The theoretical results show that there are two separating perfect Bayesian equilibria in which the prices of the conventional food and GM food are strategic complements and the profits of two types of firms are both increasing in the price of GM food. The numerical example shows that a decrease of the expected potential net damage as the most sensitive parameter leads to an increase of the profits of the two firms. Additionally, an increase in product differentiation helps to increase the two firms’ profits. Finally, the decrease in risk aversion as the second sensitive parameter helps to increase both products’ prices and quantities and both firms’ profits. This paper contributes by combining food safety regulation with market mechanisms and competition.

Asymmetric price responses, market integration and market power: A study of the U.S. natural gas market

International Nuclear Information System (INIS)

Murry, Donald; Zhu, Zhen

2008-01-01

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

On the Output-Inflation Relationship When Price and Quantity Adjustments are Costly

DEFF Research Database (Denmark)

Danziger, Leif; Kreiner, Claus Thustrup

A vast literature analyzes the real effects of price-adjustment costs assuming that quantity adjustments are costless. In this paper, we analyze whether the presence of quantity-adjustments costs, which presumably are significant, change the traditional results on the impact of inflation....... In particular, recent findings suggest that quantity-adjustment costs may remove the linkage between output and inflation. We show that this is not the case when inflation is anticipated. On the contrary, quantity-adjustment costs may significantly amplify the consequences of price-adjustment costs...

The Asymmetric Effects of Oil Price Shocks on the Chinese Stock Market: Evidence from a Quantile Impulse Response Perspective

Directory of Open Access Journals (Sweden)

Huiming Zhu

2016-08-01

Full Text Available This paper uses a quantile impulse response approach to investigate the impact of oil price shocks on Chinese stock returns. This process allows us to uncover asymmetric effects of oil price shocks on stock market returns by taking into account the different quantiles of oil price shocks. Our results show that the responses of Chinese stock market returns to oil price shocks differ greatly, depending on whether the oil and stock market is in a bust or boom state and whether the shock is driven by demand or supply. The impacts of oil price shocks on Chinese stock returns present asymmetric features. In particular during a bust phase, oil supply and demand shocks significantly depress stock market returns, while during a boom period, the aggregate demand shock enhances stock market returns. These results suggest some important implications for investors and decision makers.

Effects of asymmetric medical insurance subsidy on hospitals competition under non-price regulation.

Science.gov (United States)

Wang, Chan; Nie, Pu-Yan

2016-11-15

Poor medical care and high fees are two major problems in the world health care system. As a result, health care insurance system reform is a major issue in developing countries, such as China. Governments should take the effect of health care insurance system reform on the competition of hospitals into account when they practice a reform. This article aims to capture the influences of asymmetric medical insurance subsidy and the importance of medical quality to patients on hospitals competition under non-price regulation. We establish a three-stage duopoly model with quantity and quality competition. In the model, qualitative difference and asymmetric medical insurance subsidy among hospitals are considered. The government decides subsidy (or reimbursement) ratios in the first stage. Hospitals choose the quality in the second stage and then support the quantity in the third stage. We obtain our conclusions by mathematical model analyses and all the results are achieved by backward induction. The importance of medical quality to patients has stronger influence on the small hospital, while subsidy has greater effect on the large hospital. Meanwhile, the importance of medical quality to patients strengthens competition, but subsidy effect weakens it. Besides, subsidy ratios difference affects the relationship between subsidy and hospital competition. Furthermore, we capture the optimal reimbursement ratio based on social welfare maximization. More importantly, this paper finds that the higher management efficiency of the medical insurance investment funds is, the higher the best subsidy ratio is. This paper states that subsidy is a two-edged sword. On one hand, subsidy stimulates medical demand. On the other hand, subsidy raises price and inhibits hospital competition. Therefore, government must set an appropriate subsidy ratio difference between large and small hospitals to maximize the total social welfare. For a developing country with limited medical resources

Speed of adjustment and market structure

International Nuclear Information System (INIS)

Lanza, A.

1991-01-01

This paper studies the relationship between changes in costs and prices in the gasoline market in the Federal Republic of Germany for the period 1980-90. We shall use an econometric model, and distinguish two stages in the transmission of cost changes to prices. The first is the adjustment of gasoline prices ex-refinery to changes in the price of crude oil, and the second is the adjustment of gasoline price (net of taxes) at the pump to ex-refinery prices. The study of price adjustments to cost changes involves the analysis of two inter-related but different phenomena. The first is the speed of adjustment, defined here as the mean of the length of the time periods required for the transmission of the full effect of an exogenous shock from the independent to the dependent variable of the econometric model used in the analysis. The second relates to possible asymmetries in the response of prices to increases and decreases in costs. Both phenomena are closely related to the structure of the market. The common assumption is that the first is negatively correlated to the degree of competition, and that the second is an indication of the prevailing market structure. The main findings of this paper are as follows: (a) at the refinery level there is only weak evidence of asymmetrical reaction; the average lag in case of crude price increases or decreases is about three months; (b) at the consumers' level, the speed of adjustment was lower when the ex-refinery price was declining than when it was rising; the adjustment lag was about 6.07 months when ex-refinery prices were declining and 5.37 months when they were rising.

2017-11-20

Traditional Chinese medicine (TCM) is an important part of China's medical system. Due to the prolonged low price of TCM procedures and the lack of an effective mechanism for dynamic price adjustment, the development of TCM has markedly lagged behind Western medicine. The World Health Organization (WHO) has emphasized the need to enhance the development of alternative and traditional medicine when creating national health care systems. The establishment of scientific and appropriate mechanisms to adjust the price of medical procedures in TCM is crucial to promoting the development of TCM. This study has examined incorporating value indicators and data on basic manpower expended, time spent, technical difficulty, and the degree of risk in the latest standards for the price of medical procedures in China, and this study also offers a price adjustment model with the relative price ratio as a key index. This study examined 144 TCM procedures and found that prices of TCM procedures were mainly based on the value of medical care provided; on average, medical care provided accounted for 89% of the price. Current price levels were generally low and the current price accounted for 56% of the standardized value of a procedure, on average. Current price levels accounted for a markedly lower standardized value of acupuncture, moxibustion, special treatment with TCM, and comprehensive TCM procedures. This study selected a total of 79 procedures and adjusted them by priority. The relationship between the price of TCM procedures and the suggested price was significantly optimized (p based on a standardized value parity model is a scientific and suitable method of price adjustment that can serve as a reference for other provinces and municipalities in China and other countries and regions that mainly have fee-for-service (FFS) medical care.

Evidence of asymmetric behavioral responses to changes in gasoline prices and taxes for different fuel types

International Nuclear Information System (INIS)

Bajo-Buenestado, Raúl

2016-01-01

Using monthly data from the Spanish gasoline retail market we explore asymmetries in consumers’ behavioral responses to changes in gasoline prices and taxes. In particular, we are interested in investigating whether an increase in gasoline taxes has a more negative impact on the demand than a –similar in magnitude– increase in the “pre-tax” price of gasoline for different fuel types. We estimate fuel consumers’ responses using a rich set of robust panel data models considering potential dynamic effects and endogeneity problems. We find evidence to confirm the existence of asymmetric responses for the demand of unleaded fuels and agricultural diesel fuel. However we cannot support this statement for the regular diesel case: for this fuel both the tax-exclusive price and the tax elasticities are roughly the same. This result agrees with the fact that “diesel drivers” tend to be better informed about changes in both fuel prices and taxes. Some implications in terms of fiscal policy and pollution and climate change policy are also discussed. - Highlights: •Provide evidence of asymmetric responses of gasoline demand due to changes in prices and taxes. •Identify differences in the elasticity of the demand of diesel fuel and unleaded gasoline. •Perform robustness checks considering dynamic effects and IV regression. •Provide some policy recommendations for future gasoline tax changes.

Accounting for asymmetric price responses and underlying energy demand trends in OECD industrial energy demand

International Nuclear Information System (INIS)

Adeyemi, Olutomi I.; Hunt, Lester C.

2014-01-01

This paper explores the way technical progress and improvements in energy efficiency are captured when modelling OECD industrial energy demand. The industrial sectors of the developed world involve a number of different practices and processes utilising a range of different technologies. Consequently, given the derived demand nature of energy, it is vital when modelling industrial energy demand that the impact of technical progress is appropriately captured. However, the energy economics literature does not give a clear guide on how this can be achieved; one strand suggests that technical progress is ‘endogenous’ via asymmetric price responses whereas another strand suggests that it is ‘exogenous’. More recently, it has been suggested that potentially there is a role for both ‘endogenous’ technical progress and ‘exogenous’ technical progress and consequently the general model should be specified accordingly. This paper therefore attempts to model OECD industrial energy demand using annual time series data over the period 1962–2010 for 15 OECD countries. Using the Structural Time Series Model framework, the general specifications allow for both asymmetric price responses (for technical progress to impact endogenously) and an underlying energy demand trend (for technical progress and other factors to impact exogenously, but in a non-linear way). The results show that almost all of the preferred models for OECD industrial energy demand incorporate both a stochastic underlying energy demand trend and asymmetric price responses. This gives estimated long-run income elasticities in the range of 0.34 to 0.96; estimated long-run price-maximum elasticities in the range of − 0.06 to − 1.22; estimated long-run price-recovery elasticities in the range of 0.00 to − 0.27; and estimated long-run price-cut elasticities in the range of 0.00 to − 0.18. Furthermore, the analysis suggests that when modelling industrial energy demand there is a place for �

Do gasoline prices exhibit asymmetry? Not usually

International Nuclear Information System (INIS)

Douglas, Christopher C.

2010-01-01

Previous studies have found evidence of asymmetric price adjustment in U.S. retail gasoline prices in that gasoline prices rise more rapidly in response to a cost increase than fall in response to a cost decrease. By estimating a threshold cointegration model that allows for multiple regimes, I am able to test how sensitive this result is to outlying observations. In contrast to previous studies, I find little evidence of asymmetry for the vast majority of observations and that the asymmetry is being driven by a small number of outlying observations. (author)

Symmetric or asymmetric oil prices? A meta-analysis approach

International Nuclear Information System (INIS)

Perdiguero-García, Jordi

2013-01-01

The analysis of price asymmetries in the gasoline market is one of the most widely studied in energy economics. However, the great variation in the outcomes reported makes the drawing of any definitive conclusions difficult. Given this situation, a meta-analysis serves as an excellent tool to discover which characteristics of the various markets analyzed, and which specific features of these studies, might account for these differences. In adopting such an approach, this paper shows how the particular segment of the industry analyzed, the characteristics of the data, the years under review, the type of publication and the introduction of control variables might explain this heterogeneity in results. The paper concludes on these grounds that increased competition may significantly reduce the possibility of occurrence of asymmetric behavior. These results should be taken into consideration therefore in future studies of asymmetries in the oil industry. - Highlights: ► I study asymmetries in the price gasoline industry through a meta-analysis regression. ► The asymmetries are produced mainly in the retail market. ► The asymmetries are less frequent when we analyze recent cases. ► There may be some degree of publication bias. ► The level of competition may explain the patterns of asymmetry

A Note on Forecasting the Rate of Change of the Price of Oil: Asymmetric Loss and Forecast Rationality

Directory of Open Access Journals (Sweden)

Christian Pierdzioch

2013-03-01

Full Text Available We study whether forecasts of the rate of change of the price of oil are rational. To this end, we consider a model that allows the shape of forecasters’ loss function to be studied. The shape of forecasters’ loss function may be consistent with a symmetric or an asymmetric loss function. We find that an asymmetric loss function often (but not always makes forecasts look rational, and we also report that forecast rationality may have changed over time.

Financial Knudsen number: Breakdown of continuous price dynamics and asymmetric buy-and-sell structures confirmed by high-precision order-book information.

We generalize the description of the dynamics of the order book of financial markets in terms of a Brownian particle embedded in a fluid of incoming, exiting, and annihilating particles by presenting a model of the velocity on each side (buy and sell) independently. The improved model builds on the time-averaged number of particles in the inner layer and its change per unit time, where the inner layer is revealed by the correlations between price velocity and change in the number of particles (limit orders). This allows us to introduce the Knudsen number of the financial Brownian particle motion and its asymmetric version (on the buy and sell sides). Not being considered previously, the asymmetric Knudsen numbers are crucial in finance in order to detect asymmetric price changes. The Knudsen numbers allows us to characterize the conditions for the market dynamics to be correctly described by a continuous stochastic process. Not questioned until now for large liquid markets such as the USD-JPY and EUR-USD exchange rates, we show that there are regimes when the Knudsen numbers are so high that discrete particle effects dominate, such as during market stresses and crashes. We document the presence of imbalances of particles depletion rates on the buy and sell sides that are associated with high Knudsen numbers and violent directional price changes. This indicator can detect the direction of the price motion at the early stage while the usual volatility risk measure is blind to the price direction.

Asymmetry in retail gasoline and crude oil price movements in the United States. An application of hidden cointegration technique

International Nuclear Information System (INIS)

Honarvar, Afshin

2009-01-01

There is a common belief that gasoline prices respond more quickly to crude oil price increases than decreases. Some economists and politicians believe that asymmetry in oil and gasoline price movements is the outcome of a non-competitive gasoline market requiring that governments take policy action to address 'unfair pricing'. There is no consensus as to the existence, or nature, of the asymmetric relationship between prices of gasoline and crude oil. Much of this literature specifies asymmetry in the speed of adjustment and short-run adjustment coefficients. In contrast, Granger and Yoon's [Granger, C.W. and Yoon, G. 'Hidden Cointegration', University of California, San Diego, Department of Economics Working Paper, (2002).] Crouching Error Correction Model (CECM) identifies asymmetry of the cointegrating vectors between components (cumulative positive and negative changes) of the series. Applying the CECM to retail gasoline and crude oil prices for the U.S., we find that there is only evidence of cointegration between positive components of crude oil prices and negative components of gasoline prices. In contrast to the literature which attributes asymmetric price movements to market power of refiners, these findings suggest that gasoline prices -in the long run- are more influenced by the technological changes on the demand side than crude oil price movements on the supply side.

News impact for Turkish food prices

Directory of Open Access Journals (Sweden)

Meltem Chadwick

2017-06-01

Full Text Available Asymmetric volatility is a widely encountered concept particularly in financial series. It refers to the case that “bad news” generates more volatility than “good news” of equal magnitude. In an inflationary environment “bad news” is disclosed as increasing inflation that is expected to generate higher volatility. The present article examines whether unexpected price changes affect the volatility of prices asymmetrically for 90 retail food items of the Turkish consumer price index. These 90 food items have a weight of approximately 20 percent in headline consumer price index (CPI. We employ exponential generalized autoregressive conditional heteroscedastic (EGARCH model to extract asymmetric volatility, using monthly data between January 2003 and January 2017. Our results reveal that volatility of food prices respond asymmetrically to unexpected price shocks for 62 percent of the retail food items.

Asymmetric Effects of Global Liquidity Expansion on Foreign Portfolio Inflows, Exchange Rates, and Stock Prices

Directory of Open Access Journals (Sweden)

Dong-Eun Rhee

2014-06-01

Full Text Available This paper examines the effects of global liquidity expansion on advanced and emerging economies by using panel VAR methodology. The results show that global liquidity expansion tends to boost economy by increasing GDP growth and stock prices. However, we find that the effects are asymmetric. The effects of global liquidity on GDP and stock prices are greater and more persistent in emerging economies than in liquidity recipient advanced economies. Moreover, global liquidity appreciates emerging economies' exchange rates more persistently than those of advanced economies. Lastly, while global liquidity expansion increases foreign portfolio investment inflows to Asian countries and liquidity recipient advanced economies, there is no evidence for Latin American countries.

Actually, district heating suppliers see themselves to be exposed to the general suspicion of the claim of increased prices from their customers. Partly, the existing price adjustment clauses really do not correspond to the legal requirements. This often was complaint by the customers, and resulted in legal disputes. Under this aspect, the BET bureau for energy industry and technical planning GmbH (Aachen, Federal Republic of Germany) and FPS Attorney/Notaries (Berlin, Federal Republic of Germany) analyse and develop price models with price adjustment clauses in order to meet the resulting, often considerable risks.

Pricing a Collateralized Derivative Trade with a Funding Value Adjustment

Directory of Open Access Journals (Sweden)

Chadd B. Hunzinger

2015-01-01

Full Text Available The 2008 credit crisis changed the manner in which derivative trades are conducted. One of these changes is the posting of collateral in a trade to mitigate the counterparty credit risk. Another is the realization that banks are not risk-free and, as a result, cannot borrow at the risk-free rate any longer. The latter led banks to introduced the controversial adjustment to derivative prices, known as a funding value adjustment (FVA, which is interlinked with the posting of collateral. In this paper, we extend the Cox, Ross and Rubinstein (CRR discrete-time model to include collateral and FVA. We prove that this derived model is a discrete analogue of Piterbarg’s partial differential equation (PDE, which describes the price of a collateralized derivative. The fact that the two models coincide is also verified by numerical implementation of the results that we obtain.

How fast do stock prices adjust to market efficiency? Evidence from a detrended fluctuation analysis

Science.gov (United States)

Reboredo, Juan C.; Rivera-Castro, Miguel A.; Miranda, José G. V.; García-Rubio, Raquel

2013-04-01

In this paper we analyse price fluctuations with the aim of measuring how long the market takes to adjust prices to weak-form efficiency, i.e., how long it takes for prices to adjust to a fractional Brownian motion with a Hurst exponent of 0.5. The Hurst exponent is estimated for different time horizons using detrended fluctuation analysis-a method suitable for non-stationary series with trends-in order to identify at which time scale the Hurst exponent is consistent with the efficient market hypothesis. Using high-frequency share price, exchange rate and stock data, we show how price dynamics exhibited important deviations from efficiency for time periods of up to 15 min; thereafter, price dynamics was consistent with a geometric Brownian motion. The intraday behaviour of the series also indicated that price dynamics at trade opening and close was hardly consistent with efficiency, which would enable investors to exploit price deviations from fundamental values. This result is consistent with intraday volume, volatility and transaction time duration patterns.

Elaad, Eitan; Sayag, Neta; Ezer, Aliya

2010-08-01

Anchoring and adjustment comprise a heuristic that creates expectations. Two types of anchors were applied on participants' evaluation of products: the price reference of the product (maximum, minimum, or no price reference) and the context in which the products were evaluated (the prestige of the shopping center). Results showed that both factors anchored evaluations of products' value. Context effects were explained by the different expectations of visitors in prestigious (looking for quality) and less prestigious (seeking a bargain) centers.

Exploration of approaches to adjusting brand-name drug prices in Mainland of China: based on comparison and analysis of some brand-name drug prices of Mainland and Taiwan, China.

2014-01-01

Under the circumstance of the New Medical Reform in Mainland of China, lowering drug prices has become an approach to relieving increase of medical expenses, and lowering brand-name medication price is a key strategy. This study, by comparing and analyzing brand-name medication prices between Mainland of China and Taiwan, explores how to adjust brand-name medication prices in Mainland of China in the consideration of the drug administrative strategies in Taiwan. By selecting brand-name drug with generic name and dose types matched in Mainland and Taiwan, calculate the average unit price and standard deviation and test it with the paired t-test. In the mean time, drug administrative strategies between Mainland and Taiwan are also compared systematically. Among the 70 brand-name medications with generic names and matched dose types, 54 are at higher prices in Mainland of China than Taiwan, which is statistically significant in t-test. Also, among the 47 medications with all of matched generic names, dose types, and manufacturing enterprises, 38 are at higher prices in Mainland than Taiwan, and the gap is also statistically significant in t-test. In Mainland of China, brand-name medication took cost-plus pricing and price-based price adjustment, while in Taiwan, brand-name medication took internal and external reference pricing and market-based price adjustment. Brand-name drug prices were higher in Mainland of China than in Taiwan. The adjustment strategies of drug prices are scientific in Taiwan and are worth reference by Mainland of China.

Nonlinear joint dynamics between prices of crude oil and refined products

Science.gov (United States)

Zhang, Tao; Ma, Guofeng; Liu, Guangsheng

2015-02-01

In this paper, we investigate the relationships between crude oil and refined product prices. We find that nonlinear correlations are stronger in the long-term than in the short-term. Crude oil and product prices are cointegrated and financial crisis in 2007-2008 caused a structural break of the cointegrating relationship. Moreover, different from the findings in most studies, we reveal that the relationships are almost symmetric based on a threshold error correction model. The so-called 'asymmetric relationships' are caused by some outliers and financial crisis. Most of the time, crude oil prices play the major role in the adjustment process of the long-term equilibrium. However, refined product prices dominated crude oil prices during the period of financial crisis. Important policy and risk management implications can be learned from the empirical findings.

Testing the rationality of DOE's energy price forecasts under asymmetric loss preferences

International Nuclear Information System (INIS)

Mamatzakis, E.; Koutsomanoli-Filippaki, A.

2014-01-01

This paper examines the rationality of the price forecasts for energy commodities of the United States Department of Energy's (DOE), departing from the common assumption in the literature that DOE's forecasts are based on a symmetric underlying loss function with respect to positive vs. negative forecast errors. Instead, we opt for the methodology of Elliott et al. (2005) that allows testing the joint hypothesis of an asymmetric loss function and rationality and reveals the underlying preferences of the forecaster. Results indicate the existence of asymmetries in the shape of the loss function for most energy categories with preferences leaning towards optimism. Moreover, we also examine whether there is a structural break in those preferences over the examined period, 1997–2012. - Highlights: • Examine the rationality of DOE energy forecasts. • Departing from a symmetric underlying loss function. • Asymmetries exist in most energy prices. • Preferences lean towards optimism. • Examine structural breaks in those preferences

What policy adjustments in the EU ETS truly affected the carbon prices?

International Nuclear Information System (INIS)

Fan, Ying; Jia, Jun-Jun; Wang, Xin; Xu, Jin-Hua

2017-01-01

Carbon market becomes increasingly popular as a cost-effective instrument to mitigate CO_2 emissions. However, its construction is a learning-by-doing process, and needs consistent regulatory updates in order to deliver optimal effects. This paper uses the event study method to assess the impacts of different policy adjustments on the EUA returns in the European Union Emissions Trading Scheme (EU ETS) since 2005. Comparing to existing studies that focus on the impact of a single policy, this paper provides a complementary reference on if and to what extent policy adjustments can impact the carbon prices by classifying all regulatory update events into six categories. Its key findings are as follows. First, aggregate impacts of total 50 events studied are low while impacts of events having underlying negative impacts are higher than those having underlying positive impacts. Second, 24 events have significant impacts on EUA returns and are coherent to their theoretical impacts (except one event). Third, events having negligible impact on EUA returns are those that are announced not for the first time or those having no impact on CO_2 quotas supply and demand. Finally, there are different impact patterns: some events have different impacts on short-end and long-end carbon prices. - Highlights: • Impacts of policy adjustments in the EU ETS on carbon price are investigated. • Aggregate impacts of total 50 events studied are low. • Policy adjustments having underlying negative impacts have a higher impact. • Events that are announced for the first time are apt to have significant impact. • There are different impact patterns of events on EUA spot and futures returns.

The asymmetric, cointegrating relationship between the return on equity market and the narrowly defined money supply is documented. In fact, equity return and the monthly percentage change in the Colombian money supply M1 spread adjusts to the threshold value slower when a contractionary countercyclical policy action or an economic shock causes the money supply M1 to fall relative to the share price index, widening their spread, than when an expansionary countercyclical monetary policy action...

Implied adjusted volatility functions: Empirical evidence from Australian index option market

Science.gov (United States)

Harun, Hanani Farhah; Hafizah, Mimi

2015-02-01

This study aims to investigate the implied adjusted volatility functions using the different Leland option pricing models and to assess whether the use of the specified implied adjusted volatility function can lead to an improvement in option valuation accuracy. The implied adjusted volatility is investigated in the context of Standard and Poor/Australian Stock Exchange (S&P/ASX) 200 index options over the course of 2001-2010, which covers the global financial crisis in the mid-2007 until the end of 2008. Both in- and out-of-sample resulted in approximately similar pricing error along the different Leland models. Results indicate that symmetric and asymmetric models of both moneyness ratio and logarithmic transformation of moneyness provide the overall best result in both during and post-crisis periods. We find that in the different period of interval (pre-, during and post-crisis) is subject to a different implied adjusted volatility function which best explains the index options. Hence, it is tremendously important to identify the intervals beforehand in investigating the implied adjusted volatility function.

Oil price shocks: Sectoral and dynamic adjustments in a small-open developed and oil-exporting economy

International Nuclear Information System (INIS)

Dissou, Yazid

2010-01-01

The recent uptrend in oil prices represents both an opportunity and a challenge for small-open developed and oil-exporting countries. Using Canada as a study case and in contrast to most studies that use aggregate models, this paper employs a multi-sector, intertemporal general equilibrium model to provide perspectives on the sectoral, aggregate and dynamic adjustments of a sustained increase in oil prices. It highlights the transmission channels through which the rise in oil prices affects the domestic economy. The simulation results suggest that the shock would have positive aggregate impacts, but would also spur the reallocation of resources and would therefore induce disparities in sectoral adjustments. The suggested contraction in some industries could not however be attributed to a pure Dutch disease phenomenon because of, among other factors, the cost-push effect induced by the increase in oil prices.

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.

Does asymmetric correlation affect portfolio optimization?

Science.gov (United States)

Fryd, Lukas

2017-07-01

The classical portfolio optimization problem does not assume asymmetric behavior of relationship among asset returns. The existence of asymmetric response in correlation on the bad news could be important information in portfolio optimization. The paper applies Dynamic conditional correlation model (DCC) and his asymmetric version (ADCC) to propose asymmetric behavior of conditional correlation. We analyse asymmetric correlation among S&P index, bonds index and spot gold price before mortgage crisis in 2008. We evaluate forecast ability of the models during and after mortgage crisis and demonstrate the impact of asymmetric correlation on the reduction of portfolio variance.

The impacts of energy prices on energy intensity: Evidence from China

International Nuclear Information System (INIS)

Hang, Leiming; Tu, Meizeng

2007-01-01

In this paper, we present a review of the deregulation of energy prices in China between 1985 and 2004 and assess the impacts of changes in energy prices on aggregate energy intensity and coal/oil/electricity intensity. We used time series data to provide estimates of energy price elasticities. Empirical results showed that: (1) The own-price elasticities of coal, oil, and aggregate energy were negative in periods both before and after 1995, implying that higher relative prices of different energy types lead to the decrease in coal, oil, and aggregate energy intensities. However, the positive own-price elasticity of electricity after 1995 probably indicates that the price effect was weaker than other factors such as income effect and population effect. (2) The impacts of energy prices were asymmetric over time. (3) Sectoral adjustment also drove the decrease in aggregate energy intensity. Although raising energy prices to boost efficiency of energy use seems to be an effective policy tool, other policy implications concerned with energy prices, such as energy supply security and fuel poverty, must also be considered

Imperfect price-reversibility of US gasoline demand: Asymmetric responses to price increases and declines

International Nuclear Information System (INIS)

Gately, D.

1992-01-01

This paper describes a framework for analyzing the imperfect price-reversibility (hysteresis) of oil demand. The oil demand reductions following the oil price increases of the 1970s will not be completely reversed by the price cuts of the 1980s, nor is it necessarily true that these partial demand reversals themselves will be reversed exactly by future price increases. The author decomposes price into three monotonic series: price increases to maximum historic levels, price cuts, and price recoveries (increases below historic highs). He would expect that the response to price cuts would be no greater than to price recoveries, which in turn would be no greater than for increases in maximum historic price. For evidence of imperfect price-reversibility, he tests econometrically the following US data: vehicle miles per driver, the fuel efficiency of the automobile fleet, and gasoline demand per driver. In each case, the econometric results allow him to reject the hypothesis of perfect price-reversibility. The data show smaller response to price cuts than to price increases. This has dramatic implications for projections of gasoline and oil demand, especially under low-price assumptions. 26 refs., 13 figs., 3 tabs

Buedenbender, Ulrich; Gromm, Marcel [TU Dresden (Germany). Lehrstuhl fuer Buergerliches Recht, Energiewirtschaftsrecht und Arbeitsrecht

2011-07-01

In 2011, the BGH had to decide for the first time on price adjustment clauses. There were four court rulings on price adjustment clauses in district heat supply contracts, and price adjustment clauses were considered to be ineffective in all cases. This is a trend similar to the rulings on gas supply contracts since 2005. This contribution discusses the consequences of the 2011 BGH rulings for future price adjustment clauses in district heat supply contracts. The contract partners, especially the customers of district heating utilities, must be sure whether a raised supply price will be based on an effective price adjustment clause, or whether it will enable the customer to refuse payment.

Social Security cost-of-living adjustments and the Consumer Price Index.

Science.gov (United States)

Burdick, Clark; Fisher, Lynn

2007-01-01

OASDI benefits are indexed for inflation to protect beneficiaries from the loss of purchasing power implied by inflation. In the absence of such indexing, the purchasing power of Social Security benefits would be eroded as rising prices raise the cost of living. By statute, cost-of-living adjustments (COLAs) for Social Security benefits are calculated using the Bureau of Labor Statistics (BLS) Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Some argue that this index does not accurately reflect the inflation experienced by the elderly population and should be changed to an elderly-specific price index such as the Experimental Consumer Price Index for Americans 62 Years of Age and Older, often referred to as the Consumer Price Index for the Elderly (CPI-E). Others argue that the measure of inflation underlying the COLA is technically biased, causing it to overestimate changes in the cost of living. This argument implies that current COLAs tend to increase, rather than merely maintain, the purchasing power of benefits over time. Potential bias in the CPI as a cost-of-living index arises from a number of sources, including incomplete accounting for the ability of consumers to substitute goods or change purchasing outlets in response to relative price changes. The BLS has constructed a new index called the Chained Consumer Price Index for All Urban Consumers (C-CPI-U) that better accounts for those consumer adjustments. Price indexes are not true cost-of-living indexes, but approximations of cost-of-living indexes (COLI). The Bureau of Labor Statistics (2006a) explains the difference between the two: As it pertains to the CPI, the COLI for the current month is based on the answer to the following question: "What is the cost, at this month ' market prices, of achieving the standard of living actually attained in the base period?" This cost is a hypothetical expenditure-the lowest expenditure level necessary at this month's prices to achieve the

CASE STUDY ON RE-ADJUSTMENTS DEPENDING ON PRICE MODIFICATION

Directory of Open Access Journals (Sweden)

Cozma Ighian Diana

2011-01-01

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

Essays on microgrids, asymmetric pricing and market power in electricity markets

Science.gov (United States)

Lo Prete, Chiara

. Chapter 4 examines the possibility of asymmetric transmission of CO 2 and fuel prices to electricity futures prices in the second phase of the European Emission Trading Scheme. The goal is to assess whether output prices tend to respond more quickly to input price increases than decreases: this phenomenon is known as "rockets and feathers" in the literature. Results do not provide empirical evidence of statistically significant differences in the response of power prices to positive and negative shocks in CO 2 allowance and fuel markets. Chapter 5 re-examines the issue of the potential exercise of market power in California after liberalization, with a focus on its day-ahead energy market (the former PX) and its five largest thermal generators. The analysis focuses on a peak hour of operation (hour 18) and disregards hours in which congestion occurred. First, I define a direct measure of unilateral market power for each firm, equal to the hourly inverse elasticity of its residual demand function. The second part of the analysis aims at assessing whether the necessary conditions for the unilateral exercise of market power were satisfied in practice, based on a comparison of PX market-clearing prices, estimated marginal revenues and estimated bounds for the marginal costs of generation of each supplier. By conservatively assuming that the estimated upper bound is close to each firm's actual marginal cost of generation, the analysis suggests that in a large fraction of hours the thermal generators were acting less competitively that what implied by unilateral profit maximization. If instead I explicitly account for uncertainty in the marginal cost estimates with the introduction of a +/-10% margin on the estimated bounds, thermal generators are equally likely to bid close to their marginal costs or above them. Among the hours characterized by market-clearing prices above marginal costs, 64% present, on average, evidence of less competitive than Nash behavior. Two possible

Asymmetric impacts of international energy shocks on macroeconomic activities

2012-01-01

While limited by its scarcity of natural resources, the impacts of energy price changes on Taiwan's economic activities have been an important issue for social public and government authorities. This study applies the multivariate threshold model to investigate the effects of various international energy price shocks on Taiwan's macroeconomic activity. By separating energy price changes into the so-called decrease and increase regimes, we can realize different impacts of energy price changes and their shocks on economic output. The results confirm that there is an asymmetric threshold effect for the energy-output nexus. The optimal threshold levels are exactly where the oil price change is at 2.48%, the natural gas price change is at 0.66%, and the coal price change is at 0.25%. The impulse response analysis suggests that oil price and natural gas shocks have a delayed negative impact on macroeconomic activities. - Highlights: ► This study applies multivariate threshold model to investigate the effects of various international energy price shocks on Taiwan's macroeconomic activity. ► The results confirm that there is an asymmetric threshold effect for energy-output nexus. ► The optimal threshold levels are exactly found where oil price change is at 2.48%, natural gas price change is at 0.66%, and coal price change is at 0.25%.

Exchange rate pass-through and the frequency of price adjustment across different inflation regimes

Directory of Open Access Journals (Sweden)

Petrović Pavle

2015-01-01

Full Text Available The paper explores the link between the inflationary environment and the size of the exchange rate pass-through (ERPT into domestic prices, as inflation descends from an extreme, second highest and second longest hyperinflation in the 20th century, to high and then moderate inflation in Serbia. We found that ERPT decreases with a decline in the inflation level, variability and persistence, thus supplementing findings previously acquired in panel studies across countries. Our findings can be explained by surging empirical evidence on state contingent behavior of pricing, which indicates a sharp increase in the frequency of price adjustment as one moves from moderate, via high to hyperinflation, suggesting that the degree of price rigidities is a key determinant of the size and speed of ERPT. ERPT estimates are embedded in careful analysis of inflation episodes in Serbia, showing that hyper and high inflation episodes subscribe to the same, fiscal explanation, as opposed to the moderate inflation ones, where supply and demand shocks have been the main inflation drivers.

Effect of price elasticity of demand in monopolies with gradient adjustment

International Nuclear Information System (INIS)

Cavalli, Fausto; Naimzada, Ahmad

2015-01-01

Highlights: •A monopoly with isoelastic demand function is studied. •Reduced rationality monopolist uses gradient adjustment. •If marginal cost is small, increasing elasticity leads to stable dynamics. •For large marginal cost, dynamic can be unstable for both small and large elasticity. -- Abstract: We study a monopolistic market characterized by a constant elasticity demand function, in which the firm technology is described by a linear total cost function. The firm is assumed to be boundedly rational and to follow a gradient rule to adjust the production level in order to optimize its profit. We focus on what happens on varying the price elasticity of demand, studying the effect on the equilibrium stability. We prove that, depending on the relation between the market size and the marginal cost, two different scenarios are possible, in which elasticity has either a stabilizing or a mixed stabilizing/destabilizing effect

Ewing, Bradley T.; Thompson, Mark A.

2007-01-01

This paper examines the empirical relationship between oil prices and several key macroeconomic variables. In particular, we investigate the cyclical comovements of crude oil prices with output, consumer prices, unemployment, and stock prices. The methodology involves the use of the Hodrick-Prescott [Hodrick, R.J., Prescott, E.C., 1980. Post-War US Business Cycles: An Empirical Investigation. Working Paper, Carnegie Mellon University] and Baxter-King [Baxter, M., King, R.G., 1999. Measuring business cycles: approximate band-pass filters for economic time series. Review of Economics and Statistics 81, 575-593] filters, as well as the recently developed full-sample asymmetric Christiano-Fitzgerald [Christiano, L.J., Fitzgerald, T.J., 2003. The band pass filter. International Economic Review 44, 435-465] band-pass filter. Contemporaneous and cross-correlation estimates are made using the stationary cyclical components of the time series to make inference about the degree to which oil prices move with the cycle. Besides documenting a number of important cyclical relationships using three different time series filtering methods, the results suggest that crude oil prices are procyclical and lag industrial production. Additionally, we find that oil prices lead consumer prices. (author)

Evaluating a novel tiered scarcity adjusted water budget and pricing structure using a holistic systems modelling approach.

Science.gov (United States)

Sahin, Oz; Bertone, Edoardo; Beal, Cara; Stewart, Rodney A

2018-06-01

Population growth, coupled with declining water availability and changes in climatic conditions underline the need for sustainable and responsive water management instruments. Supply augmentation and demand management are the two main strategies used by water utilities. Water demand management has long been acknowledged as a least-cost strategy to maintain water security. This can be achieved in a variety of ways, including: i) educating consumers to limit their water use; ii) imposing restrictions/penalties; iii) using smart and/or efficient technologies; and iv) pricing mechanisms. Changing water consumption behaviours through pricing or restrictions is challenging as it introduces more social and political issues into the already complex water resources management process. This paper employs a participatory systems modelling approach for: (1) evaluating various forms of a proposed tiered scarcity adjusted water budget and pricing structure, and (2) comparing scenario outcomes against the traditional restriction policy regime. System dynamics modelling was applied since it can explicitly account for the feedbacks, interdependencies, and non-linear relations that inherently characterise the water tariff (price)-demand-revenue system. A combination of empirical water use data, billing data and customer feedback on future projected water bills facilitated the assessment of the suitability and likelihood of the adoption of scarcity-driven tariff options for a medium-sized city within Queensland, Australia. Results showed that the tiered scarcity adjusted water budget and pricing structure presented was preferable to restrictions since it could maintain water security more equitably with the lowest overall long-run marginal cost.

Asymmetric cell division requires specific mechanisms for adjusting global transcription.

Most cells divide symmetrically into two approximately identical cells. There are many examples, however, of asymmetric cell division that can generate sibling cell size differences. Whereas physical asymmetric division mechanisms and cell fate consequences have been investigated, the specific problem caused by asymmetric division at the transcription level has not yet been addressed. In symmetrically dividing cells the nascent transcription rate increases in parallel to cell volume to compensate it by keeping the actual mRNA synthesis rate constant. This cannot apply to the yeast Saccharomyces cerevisiae, where this mechanism would provoke a never-ending increasing mRNA synthesis rate in smaller daughter cells. We show here that, contrarily to other eukaryotes with symmetric division, budding yeast keeps the nascent transcription rates of its RNA polymerases constant and increases mRNA stability. This control on RNA pol II-dependent transcription rate is obtained by controlling the cellular concentration of this enzyme. © The Author(s) 2017.

Measuring core inflation in India: An asymmetric trimmed mean approach

Directory of Open Access Journals (Sweden)

Naresh Kumar Sharma

2015-12-01

Full Text Available The paper seeks to obtain an optimal asymmetric trimmed mean-based core inflation measure in the class of trimmed mean measures when the distribution of price changes is leptokurtic and skewed to the right for any given period. Several estimators based on asymmetric trimmed mean approach are constructed and estimates generated by use of these estimators are evaluated on the basis of certain established empirical criteria. The paper also provides the method of trimmed mean expression “in terms of percentile score.” This study uses 69 monthly price indices which are constituent components of Wholesale Price Index for the period, April 1994 to April 2009, with 1993–1994 as the base year. Results of the study indicate that an optimally trimmed estimator is found when we trim 29.5% from the left-hand tail and 20.5% from the right-hand tail of the distribution of price changes.

In this paper, we provide two main innovations: (i) we analyze oil prices of two prominent markets namely West Texas Intermediate (WTI) and Brent using the two recently developed tests by Narayan and Popp (2010) and Liu and Narayan, 2010 both of which allow for two structural breaks in the data series; and (ii) the latter method is modified to include both symmetric and asymmetric volatility models. We identify two structural breaks that occur in 1990 and 2008 which coincidentally correspond to the Iraqi/Kuwait conflict and the global financial crisis, respectively. We find evidence of persistence and leverage effects in the oil price volatility. While further extensions can be pursued, the consideration of asymmetric effects as well as structural breaks should not be jettisoned when modelling oil price volatility. - Highlights: ► We analyze oil price volatility using NP (2010) and LN (2010) tests. ► We modify the LN (2010) to account for leverage effects in oil price. ► We find two structural breaks that reflect major global crisis in the oil market. ► We find evidence of persistence and leverage effects in oil price volatility. ► Leverage effects and structural breaks are fundamental in oil price modelling.

Adjusting the CO2 cap to subsidised RES generation: Can CO2 prices be decoupled from renewable policy?

Highlights: • Strong renewable policy can cause price drops in an emission trading system (ETS). • Cap reduction based on exceedance of original policy goals could prevent price drops. • Dynamic cap reduction makes renewable policy climate effective in an ETS. • Dynamic cap reduction is not useful for reaching carbon price or volatility goals. • Dynamic cap reduction could undo the “green promotes the dirtiest” effect. - Abstract: The low prices in the European Emission Trading System (EU ETS) have triggered discussions of various possible reforms. One option is to decouple the CO 2 prices from renewable energy policy by adjusting the emission cap to renewable energy investment overshoots. We introduce two ways of reducing the CO 2 cap in response to overshoots of renewable policy investment over previously announced targets. We investigate these options with the agent-based model EMLab-generation. We find that both policy implementations are successful in restoring prices. They also ensure that making public investments that exceed policy targets contribute to carbon emission reduction, and that renewable policy does not benefit the most emission-intensive power plants. However, neither policy is suitable for achieving specifc levels of prices or price volatility

Analyzing the statistical features of fluctuation is remarkably significant for financial risk identification and measurement. In this study, the asymmetric detrended fluctuation analysis (A-DFA) method was applied to evaluate asymmetric multifractal scaling behaviors in the Shanghai and New York gold markets. Our findings showed that the multifractal features of the Chinese and international gold spot markets were asymmetric. The gold return series persisted longer in an increasing trend than in a decreasing trend. Moreover, the asymmetric degree of multifractals in the Chinese and international gold markets decreased with the increase in fluctuation range. In addition, the empirical analysis using sliding window technology indicated that multifractal asymmetry in the Chinese and international gold markets was characterized by its time-varying feature. However, the Shanghai and international gold markets basically shared a similar asymmetric degree evolution pattern. The American subprime mortgage crisis (2008) and the European debt crisis (2010) enhanced the asymmetric degree of the multifractal features of the Chinese and international gold markets. Furthermore, we also make statistical tests for the results of multifractatity and asymmetry, and discuss the origin of them. Finally, results of the empirical analysis using the threshold autoregressive conditional heteroskedasticity (TARCH) and exponential generalized autoregressive conditional heteroskedasticity (EGARCH) models exhibited that good news had a more significant effect on the cyclical fluctuation of the gold market than bad news. Moreover, good news exerted a more significant effect on the Chinese gold market than on the international gold market.

Essays on pricing dynamics, price dispersion, and nested logit modelling

Science.gov (United States)

Verlinda, Jeremy Alan

The body of this dissertation comprises three standalone essays, presented in three respective chapters. Chapter One explores the possibility that local market power contributes to the asymmetric relationship observed between wholesale costs and retail prices in gasoline markets. I exploit an original data set of weekly gas station prices in Southern California from September 2002 to May 2003, and take advantage of highly detailed station and local market-level characteristics to determine the extent to which spatial differentiation influences price-response asymmetry. I find that brand identity, proximity to rival stations, bundling and advertising, operation type, and local market features and demographics each influence a station's predicted asymmetric relationship between prices and wholesale costs. Chapter Two extends the existing literature on the effect of market structure on price dispersion in airline fares by modeling the effect at the disaggregate ticket level. Whereas past studies rely on aggregate measures of price dispersion such as the Gini coefficient or the standard deviation of fares, this paper estimates the entire empirical distribution of airline fares and documents how the shape of the distribution is determined by market structure. Specifically, I find that monopoly markets favor a wider distribution of fares with more mass in the tails while duopoly and competitive markets exhibit a tighter fare distribution. These findings indicate that the dispersion of airline fares may result from the efforts of airlines to practice second-degree price discrimination. Chapter Three adopts a Bayesian approach to the problem of tree structure specification in nested logit modelling, which requires a heavy computational burden in calculating marginal likelihoods. I compare two different techniques for estimating marginal likelihoods: (1) the Laplace approximation, and (2) reversible jump MCMC. I apply the techniques to both a simulated and a travel mode

Coupled effects of market impact and asymmetric sensitivity in financial markets

Science.gov (United States)

Zhong, Li-Xin; Xu, Wen-Juan; Ren, Fei; Shi, Yong-Dong

2013-05-01

By incorporating market impact and asymmetric sensitivity into the evolutionary minority game, we study the coevolutionary dynamics of stock prices and investment strategies in financial markets. Both the stock price movement and the investors’ global behavior are found to be closely related to the phase region they fall into. Within the region where the market impact is small, investors’ asymmetric response to gains and losses leads to the occurrence of herd behavior, when all the investors are prone to behave similarly in an extreme way and large price fluctuations occur. A linear relation between the standard deviation of stock price changes and the mean value of strategies is found. With full market impact, the investors tend to self-segregate into opposing groups and the introduction of asymmetric sensitivity leads to the disappearance of dominant strategies. Compared with the situations in the stock market with little market impact, the stock price fluctuations are suppressed and an efficient market occurs. Theoretical analyses indicate that the mechanism of phase transition from clustering to self-segregation in the present model is similar to that in the majority-minority game and the occurrence and disappearance of efficient markets are related to the competition between the trend-following and the trend-aversion forces. The clustering of the strategies in the present model results from the majority-wins effect and the wealth-driven mechanism makes the market become predictable.

Separated influence of crude oil prices on regional natural gas import prices

International Nuclear Information System (INIS)

Ji, Qiang; Geng, Jiang-Bo; Fan, Ying

2014-01-01

This paper analyses the impact of global economic activity and international crude oil prices on natural gas import prices in three major natural gas markets using the panel cointegration model. It also investigates the shock impacts of the volatility and the increase and decrease of oil prices on regional natural gas import prices. The results show that both global economic activity and international crude oil prices have significant long-term positive effects on regional natural gas import prices. The volatility of international crude oil prices has a negative impact on regional natural gas import prices. The shock impact is weak in North America, lags in Europe and is most significant in Asia, which is mainly determined by different regional policies for price formation. In addition, the response of natural gas import prices to increases and decreases in international crude oil prices shows an asymmetrical mechanism, of which the decrease impact is relatively stronger. - Highlights: • Impacts of world economy and oil prices on regional natural gas prices are analysed • North American natural gas prices are mainly affected by world economy • Asian and European natural gas prices are mainly affected by oil prices • The volatility of oil prices has a negative impact on regional natural gas prices • The response of natural gas import prices to oil prices up and down shows asymmetry

Essays on the behavior of the oil market and OPEC

Science.gov (United States)

Algudhea, Salim

This dissertation consists of three essays. The first essay is mainly concerned with investigating the risk-responsive behavior of OPEC members. Economic theory suggests that producers respond to the risk of volatile price by lowering production level. In the case of OPEC, the risk of the volatility in the price of crude oil does not seem to be a key determinant in the production decision-making process. Engineering constraints, data frequency, and political consideration may be the main causes of such a result. In the second essay, we tested the presence of the asymmetric adjustment in the cheating behavior as a result of crude oil price shocks. We utilize a set of cointegration and error correction methods that do not assume a linear adjustment to test whether cheaters within OPEC respond more to positive or negative crude oil price shocks. We conclude that cheaters respond more to negative shocks than positive shocks in oil price. The inelastic nature of demand for oil seems to play a crucial role in such asymmetric behavior. When there is a negative price shock, OPEC producers compensate for the loss in revenue by overproducing (i.e. cheat). Yet, if there is a positive shock in the price of crude oil, OPEC producers have less incentive to overproduce because of the inelastic demand for oil. The third essay is concerned with testing for the asymmetric adjustment in gasoline prices in the U.S. We consider a Momentum Threshold Autoregressive (MTAR) process to test for the asymmetric adjustment in all of the possible stages that a gallon of gasoline goes through in order to find the source of asymmetry. Then, we examine the dynamics of gasoline prices using asymmetric error correction models based on the MTAR specifications. We find the asymmetric adjustment present in all stages. The asymmetry in the retail stage seems to be the result of insufficient demand faced by retailers.

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

Bagnai, Alberto; Mongeau Ospina, Christian Alexander

2015-01-01

Using monthly data from 1994 to 2013 we study the long-run relation of the pre-tax retail prices of gasoline with crude price and the nominal exchange rate. We find a strongly significant long-run relation. We then use the nonlinear ARDL (NARDL) model to assess the asymmetries on both the short- and long-run elasticities, as well as the presence of hysteresis in the pricing behaviour. The estimation results confirm the presence of asymmetry in the long-run elasticities, with significant differences between the crude price and the exchange rate, as well as the presence of hysteresis in the relation between the retail price of gasoline and crude oil price. - Highlights: • The pass-through of crude oil prices and exchange rate into gasoline prices is examined. •We use an extended NARDL model to test for asymmetric reactions and hysteresis. • Asymmetric pricing behaviour features only in the long run. • The sign of the asymmetry differs between exchange rate and crude price changes. • The results are robust to the inclusion of several variables usually related to asymmetry

Montes, A; Villalbí, J R

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.

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

International Nuclear Information System (INIS)

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.

This paper chose the wholesale price of litchi as research object based on the daily data of 11 main sales markets in China -- Beijing, Chengdu, Guangzhou, Hefei, Jiaxing, Nanjing, Shanghai, Shenyang, Changsha, Zhengzhou and Chongqing from April 1, 2012 to September 30, 2016. After analyzing the fluctuation characteristics with BP filter method and H-P filter method, and the fluctuation trends of litchi wholesale price in China obtained by BP filter are roughly consistent with the trends obtained by H-P filter. The main conclusions are as follows: there is strong cyclicality in the fluctuation of litchi wholesale price; the period of fluctuations of litchi wholesale prices are not repeatable; litchi wholesale price fluctuates asymmetrically in one fluctuation cycle.

How does market concern derived from the Internet affect oil prices?

2013-01-01

Highlights: • The impact of market concern derived from the Web on oil volatility is analysed. • It has an equilibrium relationship between oil prices and long-run market concern. • The short-run market concerns have an asymmetric influence on oil price volatility. • The Internet can exaggerate the impact of information shocks on oil price. - Abstract: With the acceleration of oil marketisation and the rapid development of electronic information carriers, external information shocks can be easily and quickly transmitted to the oil market through the Internet. This paper analyses the impact of short- and long-run market concerns, derived from search query volumes in Google for different domains around the oil market on oil volatility using co-integration and the modified EGARCH model. Empirical results suggest there is a long-term equilibrium relationship between oil prices and long-run market concern for oil prices and oil demand. The short-run market concerns for the 2008 financial crisis and the Libyan war convulsion have a significant and asymmetric influence on oil price volatility. This indicates that market concern transmitted through the Internet can strengthen the linkage between oil price changes and external events by influencing the expectation of market traders, and to some extent it can exaggerate the impact of nonfundamental information shocks

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.

The objective of this paper is to assess the degree and the structure of price dependence in the principal EU olive oil markets (Spain, Italy and Greece). To this end, it utilizes monthly olive oil price data and the statistical tool of copulas. The empirical results suggest that prices are likely to boom together but not to crash together; this is especially true for the prices of the two most important players, Italy (importer) and Spain (exporter). The finding of asymmetric price co-movements implies that the three principal spatial olive oil markets in the EU cannot be thought of as one great pool. (Author)

We generally consider that the price elasticity of the energy demand is quite small. But it appears that strong increases in gasoline price lead to modifications in consumer behaviours. The high volatility of petroleum prices and thus gasoline prices and the strong increases since the beginning of 2000 justify an analysis of price effects on gasoline consumption. Thus, in this paper, we estimate the effects of price variations on gasoline consumption, in the short and the long-term, in two countries: the United States and India. We use a co-integration modelling to test for long-run relationship between gasoline consumption, income, price and vehicle ownership in the two countries. We use an error correction model to test for short-run prices effects and more precisely for asymmetric effects on demand of increases and decreases in gasoline prices.

Full Text Available This paper examines the impact of oil prices on real stock returns for Brazil, China, India and Russia over 1999:1-2009:9 using VAR models. The results suggest that whereas real stock returns positively respond to some of the oil price indicators with statistical significance for China, India and Russia, those of Brazil do not show any significant responses. In addition, statistically significant asymmetric effects of oil price increases and decreases are observed in India. The analysis of variance decomposition shows that the contribution of oil price shocks to volatility in real stock returns is relatively large and statistically significant for China and Russia.

This purpose of this paper is to investigate price transmission patterns through selected Danish food chains – from primary production to processing, from processing to wholesale and from wholesale to retail prices. Specifically, the study addresses the following research questions: To what extent...... are commodity prices transmitted from one stage to another in the food chain? What is the time horizon in the price transmission? Is price transmission symmetric – in the short run and in the long run? Is the degree of price transmission affected by the degree of concentration in the supply and demand stage...... considered? These questions are analysed theoretically and empirically using econometric analysis. 6 food chains are investigated: pork, chicken, eggs, milk, sugar and apples. Preliminary empirical results suggest that for most commodities, price transmission tends to be upward asymmetric, i.e. stronger...

The Earnings/Price Risk Factor in Capital Asset Pricing Models

Directory of Open Access Journals (Sweden)

Rafael Falcão Noda

2015-01-01

Full Text Available This article integrates the ideas from two major lines of research on cost of equity and asset pricing: multi-factor models and ex ante accounting models. The earnings/price ratio is used as a proxy for the ex ante cost of equity, in order to explain realized returns of Brazilian companies within the period from 1995 to 2013. The initial finding was that stocks with high (low earnings/price ratios have higher (lower risk-adjusted realized returns, already controlled by the capital asset pricing model's beta. The results show that selecting stocks based on high earnings/price ratios has led to significantly higher risk-adjusted returns in the Brazilian market, with average abnormal returns close to 1.3% per month. We design asset pricing models including an earnings/price risk factor, i.e. high earnings minus low earnings, based on the Fama and French three-factor model. We conclude that such a risk factor is significant to explain returns on portfolios, even when controlled by size and market/book ratios. Models including the high earnings minus low earnings risk factor were better to explain stock returns in Brazil when compared to the capital asset pricing model and to the Fama and French three-factor model, having the lowest number of significant intercepts. These findings may be due to the impact of historically high inflation rates, which reduce the information content of book values, thus making the models based on earnings/price ratios better than those based on market/book ratios. Such results are different from those obtained in more developed markets and the superiority of the earnings/price ratio for asset pricing may also exist in other emerging markets.

Service quality and asymmetric information in the regulation of monopolies: The Chilean electricity distribution industry

Science.gov (United States)

Melo, Oscar Alfredo

This study is an enquiry about the role that service quality, asymmetric information, scope of regulation and regulator's preferences play in the regulation of monopolies, with an application to the case of the Chilean electricity distribution industry. In Chapter 1, I present the problem of regulating a monopolist and introduce the special conditions that the electricity sector has. Later I discuss the main characteristics of the electricity system that operates in Chile. The literature on regulation is reviewed in Chapter 2. A special emphasis is given to the problems of quality and information, and the lack of its proper joint treatment. In Chapter 3, I develop four theoretical models of regulation that explicitly consider the regulation of price and quality versus price-only regulation, and a symmetric versus asymmetric information structure where only the regulator knows its true costs. In these models, I also consider the effect of a regulator that may have a preference between consumers and the regulated monopolistic firms. I conclude that with symmetric information and independent of the scope of regulation, having a regulator that prefers consumers or producers does not affect the efficiency of the outcome. I also show that the regulator's inability to set quality, thus regulating only price, leads to an inefficient outcome, away from the first best solution that can be achieved by regulating both price and quality, even with asymmetric information, as long as the regulator does not have a "biased" preference for consumers or the monopolistic producers. If the regulator has a "bias," then the equilibrium will be inefficient with asymmetric information. But the effect on equilibrium price and quality depends on the direction of the effect of quality on the marginal effect of price in demand. More importantly, no closed-form solution can be derived unless drastic simplifications are made. To further investigate the outcome of the models, I use numerical

A measure of marketing price transmission in the rice market of Taiwan

Directory of Open Access Journals (Sweden)

Yuan-Ming Lee

2009-12-01

Full Text Available The goal of this paper is to test whether changes in the marketing margin betweenthe farm and the retail prices can result in an asymmetric relationship between the farm and the retail prices in the rice market of Taiwan. By separating the transaction cost variation into two regimes, this paper utilizes a two-regime TVECM with the error correction term serving as the threshold variable to create a non-linear threshold model. The empirical results show that when the marketing margin is lower than the threshold value, the market system operates freely and there is feedback between the farm and retail prices. However, when the marketing margin is higher than the threshold value, the government intervenes in the market and the causality between the farm and retail prices no longer exists. The conclusions are as follows. Changes in the marketing margin can cause the asymmetric price transmission between the farm and retail prices in Taiwan’s rice markets; therefore, ignoring the effect of the marketing margin could lead to errors in the models. When the marketing margin is higher than the threshold value, the government intervenes in the market and the causality between the two prices is broken.

The impacts of global oil price shocks on China's fundamental industries

International Nuclear Information System (INIS)

Wang, Xiao; Zhang, Chuanguo

2014-01-01

This paper investigated the impacts of oil price shocks on China's fundamental industries. In order to analyze the reactions of different industries to oil price shocks, we focused on four fundamental industries: grains, metals, petrochemicals and oil fats. We separated the oil price shocks into two parts, positive and negative parts, to investigate how commodity markets react when oil prices go up and down. We further studied the extreme price movements, called jumps, existing in the oil markets and how jump behavior has affected China's commodity markets. Our results suggest that asymmetric effects of oil price shocks did exist in the four markets and the negative oil price shocks had stronger influences on the four markets in China. The petrochemicals market suffered most from the oil price shocks, and the grains market was least sensitive to the shocks. When jumps occurred in the crude oil market, the four commodity markets would be affected differently. The oil fats market and petrochemicals market tended to “overreact” to jumps. - Highlights: • We investigate the impacts of oil price shocks on China's fundamental industries. • Jump behavior does exist in the crude oil market. • The impacts of oil price shocks are asymmetric. • China's four commodity markets are affected by the jump behavior

Pricing Unmetered Irrigation Water under Asymmetric Information and Full Cost Recovery

Directory of Open Access Journals (Sweden)

Alban Lika

2016-12-01

Full Text Available The objective of this study is to define an efficient pricing scheme for irrigation water in conditions of unmetered water use. The study is based on a principal-agent model and identifies a menu of contracts, defined as a set of payments and share of irrigated area, able to provide incentives for an efficient use of the resource by maximizing social welfare. The model is applied in the case study of the Çukas region (Albania where irrigation water is not metered. The results demonstrate that using a menu of contracts makes it possible to define a second best solution that may improve the overall social welfare derived from irrigation water use compared with the existing pricing structure, though, in the specific case study, the improvement is small. Furthermore, the results also suggest that irrigation water pricing policy needs to take into account different farm types, and that appropriate contract-type pricing schemes have a potential role in providing incentives to farmers to make irrigation choices to the social optimum.

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.

New evidence on the asymmetry in gasoline price: volatility versus margin?

International Nuclear Information System (INIS)

Abosedra, S.; Radchenko, S.

2006-01-01

This paper examines recent evidence on the role that gasoline margins and volatility play in the asymmetric response of gasoline prices to changes in oil prices at different stages of distribution process. In a regression model with margins, we find that margins are statistically significant in explaining asymmetry between crude oil and spot gasoline prices, spot gasoline prices and wholesale gasoline prices, and wholesale gasoline prices and retail prices. In a regression model with input volatility, we find evidence that volatility is responsible for asymmetry between wholesale gasoline prices and retail gasoline prices. When both, gasoline margins and gasoline volatility are included in the regression, we find evidence supporting margins, the search theory, volatility, the oligopolistic coordination theory and an explanation of asymmetry.

Price smarter on the Net.

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.

Short- and long-run adjustments in U.S. petroleum consumption

International Nuclear Information System (INIS)

Huntington, Hillard G.

2010-01-01

Long-run adjustments in petroleum consumption are not only larger than short-run adjustments. They may also be motivated by entirely different price events. This analysis shows that new price peaks have both short-run and long-run consumption responses, a result that is starkly different than price changes that track previous price paths. It also establishes significant trend effects where gasoline and residual fuel oil consumption decline over time. The analysis explores these adjustments by establishing long-run cointegrating relationships for different petroleum product groupings. An important implication is that price increases above historical levels may be providing substantially greater incentives for significant long-run demand adjustments than would be the case otherwise.

Exporter Price Premia?

DEFF Research Database (Denmark)

Jäkel, Ina Charlotte; Sørensen, Allan

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

Utilizing TOPSIS intensified with adjustment similarity factor to determine price of technology

Seyed Mohammad Seyedhosseini

2012-08-01

Full Text Available Technology transfer has been a very frequent activity in the industrial world nowadays. Technology valuation, and in particular technology pricing, has played a considerable role in these transactions, in spite of a huge amount of limitations in the pricing methodologies applied. Making a sound, traceable and reliable means for applying the price evaluation procedure, seems as a technological requirement to be traced for. The objective of delivering this paper is to introduce a new numerical technology pricing method to provide the two transacting parties a unique compromised price. A three-dimensional model for technology pricing is proposed and The TOPSPS algorithm has been utilized to select the most similar technologies to the intended one and the constructed scoring system is applied to calculate the final technology price accordingly.

This paper investigates how financial market imperfections and the frequency of price adjustment interact. Based on new firm-level evidence for Germany, we document that financially constrained firms adjust prices more often than their unconstrained counterparts, both upwards and downwards. We show...... that these empirical patterns are consistent with a partial equilibrium menu-cost model with a working capital constraint. We then use the model to show how the presence of financial frictions changes profits and the price distribution of firms compared to a model without financial frictions.

Moreover, in response to aggregate shocks, aggregate price rigidity moves substantially, the response of inflation is dampened, while output reacts more in the presence of financial frictions...

Asymmetric conditional volatility in international stock markets

Science.gov (United States)

Ferreira, Nuno B.; Menezes, Rui; Mendes, Diana A.

2007-08-01

Recent studies show that a negative shock in stock prices will generate more volatility than a positive shock of similar magnitude. The aim of this paper is to appraise the hypothesis under which the conditional mean and the conditional variance of stock returns are asymmetric functions of past information. We compare the results for the Portuguese Stock Market Index PSI 20 with six other Stock Market Indices, namely the SP 500, FTSE 100, DAX 30, CAC 40, ASE 20, and IBEX 35. In order to assess asymmetric volatility we use autoregressive conditional heteroskedasticity specifications known as TARCH and EGARCH. We also test for asymmetry after controlling for the effect of macroeconomic factors on stock market returns using TAR and M-TAR specifications within a VAR framework. Our results show that the conditional variance is an asymmetric function of past innovations raising proportionately more during market declines, a phenomenon known as the leverage effect. However, when we control for the effect of changes in macroeconomic variables, we find no significant evidence of asymmetric behaviour of the stock market returns. There are some signs that the Portuguese Stock Market tends to show somewhat less market efficiency than other markets since the effect of the shocks appear to take a longer time to dissipate.

Have oil and gas prices got separated?

International Nuclear Information System (INIS)

Erdős, Péter

2012-01-01

This paper applies vector error correction models that show that oil and natural gas prices decoupled around 2009. Before 2009, US and UK gas prices had a long-term equilibrium with crude prices to which gas prices always reverted after exogenous shocks. Both US and UK gas prices adjusted to the crude oil price individually, and departure from the equilibrium gas price on one continent resulted in a similar departure on the other. After an exogenous shock, the adjustment between US and UK gas prices took approximately 20 weeks on average, and the convergence was mediated mainly by crude oil with a necessary condition that arbitrage across the Atlantic was possible. After 2009, however, the UK gas price has remained integrated with oil price, but the US gas price decoupled from crude oil price and the European gas price, as the Atlantic arbitrage has halted. The oversupply from shale gas production has not been mitigated by North American export, as there has been no liquefying and export capacity. - Highlights: ► VEC models are applied to investigate the relationship between oil and natural gas prices. ► While natural gas prices in Europe and Asia react to oil price, US gas price decoupled from oil in 2009. ► Since 2009, the US gas price has decoupled from the European and Asian gas prices.

Do oil price shocks matter? Evidence for some European countries

2003-01-01

This paper analyzes the oil price-macro economy relationship by means of analyzing the impact of oil prices on inflation and industrial production indexes for many European countries using quarterly data for the period 1960-1999. First, we test for cointegration allowing for structural breaks among the variables. Second, and in order to account for the possible non-linear relationships, we use different transformation of oil price data. The main results suggest that oil prices have permanent effects on inflation and short run but asymmetric effects on production growth rates. Furthermore, significant differences are found among the responses of the countries to these shocks. (Author)

2016-01-01

In financial markets, the relation between fluctuations of stock prices and trading behaviors is complex. It is intriguing to quantify this kind of meta-correlation between market fluctuations and the synchronous behaviors. We refine the theoretical index leverage model proposed by Reigneron et al. , to exactly quantify the meta-correlation under various levels of price fluctuations [Reigneron P A, Allez R and Bouchaud J P 2011 Physica A 390 3026]. The characteristics of meta-correlations in times of market losses, are found to be significantly different in Chinese and American financial markets. In addition, unlike the asymmetric results at the daily scale, the correlation behaviors are found to be symmetric at the high-frequency scale. (paper)

Full Text Available The article is focused on analysis of price transmission along the wheat commodity chain in the Czech Republic, with the distinction on wheat products with low value added (wheat flour, respectively high value added (wheat rolls. The degree of vertical price transmission is measured to identify potential market failures, because asymmetric price transmission can be the result of existence of market power within the food commodity chain. The data basis is made up from monthly prices on partial markets of the analyzed commodity chain published by Czech Statistical Office and Ministry of Agriculture of the Czech Republic. The monitored time period is from January 2000 till October 2009. The analysis is based on calculation of the price transmission elasticity coefficient (evaluation of price transmission along the chain and the intensity of dependency of positive and negative inter-market price differences (evaluation whether positive or negative price changes are better transmitted among particular vertical markets. Time lag is tested as well. The assessment of price transmission along the wheat commodity chain confirmed the existence of market power especially on the retail stage and low impact of price changes of farm prices on final consumer food prices.

How German Online Retailers Price Foods: An Empirical Analysis for Chocolate Products

Directory of Open Access Journals (Sweden)

Svetlana Fedoseeva

2017-01-01

Full Text Available Despite the increasing importance of online grocery retailing, little is known about price dispersion across online providers, the relation between online and offline prices as well as the frequency of price adjustments. We employ means of descriptive and inductive statistics as well as panel econometrics to address these issues for German online food retailers. Daily online prices for twelve chocolate products charged by eight pure online and multichannel retailers and collected over three months are investigated. Information economics suggests that a maturing online market will call forth more price homogeneity online due to lower search costs by consumers as well as more flexible prices due to lower costs of price adjustments by retailers. Our results suggest, however, that neither homogenous prices nor frequent price adjustments do occur on the German online chocolate market.

Oil Price and Economic Resilience. Romania’s Case

Directory of Open Access Journals (Sweden)

Monica Dudian

2017-02-01

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

Estimating the Efficiency and Impacts of Petroleum Product Pricing Reforms in China

Directory of Open Access Journals (Sweden)

Chuxiong Deng

2018-04-01

Full Text Available The efficiency and effects analysis of a new pricing mechanism would have significant policy implications for the further design of a pricing mechanism in an emerging market. Unlike most of the existing literature, which focuses on the impacts to the macro-economy, this paper firstly uses an econometrics model to discuss the efficiency of the new pricing mechanism, and then establishes an augmented Phillips curve to estimate the impact of pricing reform on inflation in China. The results show that: (1 the new pricing mechanism would strengthen the linkage between Chinese oil prices and international oil prices; (2 oil price adjustments are still inadequate in China. (3 The lag in inflation is the most important factor that affects inflation, while the impact of the Chinese government’s price adjustments on inflation is limited and insignificant. In order to improve the efficiency of the petroleum products pricing mechanism and shorten lags, government should shorten the adjustment period and diminish the fluctuation threshold.

Dynamics of oil price, precious metal prices, and exchange rate

International Nuclear Information System (INIS)

Sari, Ramazan; Soytas, Ugur; Hammoudeh, Shawkat

2010-01-01

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

A study of Canadian retail gasoline prices

International Nuclear Information System (INIS)

Eckert, A.L.

1999-05-01

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

The transitory and permanent volatility of oil prices: What implications are there for the US industrial production?

2012-01-01

Highlights: ► This study examines the impact of oil price uncertainty on the US industrial production (IPI). ► The transitory component of the oil price volatility has an adverse impact on the US IPI. ► The transitory oil price volatility induces higher volatility in CPI, commodity prices and IPI. -- Abstract: This study examines the impact of oil price uncertainty on the US industrial production by decomposing oil price volatility into permanent and transitory components. The decompositions provide important evidence on sources and asymmetric effects of oil price volatility. To estimate the component structure of volatility and to analyse the dynamic impacts of the volatility components, the study uses a threshold based CGARCH and VAR modelling over a period from 1980 to 2010 for the US economy. The CGARCH model estimates show significant asymmetric effect of oil price shock on the transitory oil price volatility. Dynamic impulse response functions obtained from the estimated VAR models reveal that there is a significant and prolonged dampening impact of increased transitory oil price volatility on industrial production. The results also suggest that shocks to transitory component induce increased volatility in the general price level and non-fuel commodity prices in the US. Variance decomposition analysis reconfirms that the transitory volatility is the second most important factor to explain the variance of industrial production. These results provide additional insights on the sources of oil price uncertainty and point to the need to direct US energy policies towards stabilising short-term uncertainties in oil prices.

Controllable asymmetric transmission via gap-tunable acoustic metasurface

Science.gov (United States)

Liu, Bingyi; Jiang, Yongyuan

2018-04-01

In this work, we utilize the acoustic gradient metasurface (AGM) of a bilayer configuration to realize the controllable asymmetric transmission. Relying on the adjustable gap between the two composing layers, the metasurface could switch from symmetric transmission to asymmetric transmission at a certain gap value. The underlying mechanism is attributed to the interference between the forward diffracted waves scattered by the surface bound waves at two air-AGM interfaces, which is apparently influenced by the interlayer distance. We further utilize the hybrid acoustic elements to construct the desired gradient metasurface with a tunable gap and validate the controllable asymmetric transmission with full-wave simulations. Our work provides the solution for actively controlling the transmission property of an acoustic element, which shows potential application in acoustic communication as a dynamic tunable acoustic diode.

Three components of postural control associated with pushing in symmetrical and asymmetrical stance.

A number of occupational and leisure activities that involve pushing are performed in symmetrical or asymmetrical stance. The goal of this study was to investigate early postural adjustments (EPAs), anticipatory postural adjustments (APAs), and compensatory postural adjustments (CPAs) during pushing performed while standing. Ten healthy volunteers stood in symmetrical stance (with feet parallel) or in asymmetrical stance (staggered stance with one foot forward) and were instructed to use both hands to push forward the handle of a pendulum attached to the ceiling. Bilateral EMG activity of the trunk and leg muscles and the center of pressure (COP) displacements in the anterior-posterior (AP) and medial-lateral (ML) directions were recorded and analyzed during the EPAs, APAs, and CPAs. The EMG activity and the COP displacement were different between the symmetrical and asymmetrical stance conditions. The COP displacements in the ML direction were significantly larger in staggered stance than in symmetrical stance. In staggered stance, the EPAs and APAs in the thigh muscles of the backward leg were significantly larger, and the CPAs were smaller than in the forward leg. There was no difference in the EMG activity of the trunk muscles between the stance conditions. The study outcome confirmed the existence of the three components of postural control (EPAs, APAs, and CPAs) in pushing. Moreover, standing asymmetrically was associated with asymmetrical patterns of EMG activity in the lower extremities reflecting the stance-related postural control during pushing. The study outcome provides a basis for studying postural control during other daily activities involving pushing.

Airport Pricing Strategies

Science.gov (United States)

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).

Liu, Chang; Sun, Xiaolei; Chen, Jianming; Li, Jianping

2016-01-01

This paper focuses on the application of panel models for identification and analysis of influence of oil price volatility on statistical properties of country risk ratings which stem from uncertainty of macroeconomic fluctuations. Firstly, two statistical properties of country risk ratings, volatility clustering and asymmetrical revision were identified in a theoretical framework based on Cruces (2006). Secondly, considering the oil price volatility, numerical experiments were conducted based on extended models to test and verify specific properties of country risk ratings in selected oil-exporting countries. Empirical results suggest that properties of country risk remain comparatively steady despite oil price volatility. It is also found that the oil price volatility can obviously exaggerate the country risk volatility, as it happened during 2007–2009. Country clustering based on the properties of country risk ratings shows that the selected countries maintain a significant clustering tendency. These features are of great importance for estimating risk exposure of international trade and investments in oil export during extreme situations. - Highlights: •Relationship between oil price volatility and country risk is the focus. •An extended model based on Cruces (2006) is proposed. •Volatility clustering and asymmetrical revision of country risk ratings is explored. •Oil price volatility can obviously exaggerate properties of country risk volatility.

Symmetrization of the beam-beam interaction in an asymmetric collider

International Nuclear Information System (INIS)

Chin, Y.H.

1990-07-01

This paper studies the idea of symmetrizing both the lattice and the beams of an asymmetric collider, and discusses why this regime should be within the parametric reach of the design in order to credibly ensure its performance. Also examined is the effectiveness of a simple compensation method using the emittance as a free parameter and that it does not work in all cases. At present, when there are no existing asymmetric colliders, it seems prudent to design an asymmetric collider so as to be similar to a symmetric one (without relying on a particular theory of the asymmetric beam-beam interaction that has not passed tests of fidelity). Nevertheless, one must allow for the maximum possible flexibility and freedom in adjusting those parameters that affect luminosity. Such a parameter flexibility will be essential in tuning the collider to the highest luminosity

How firms set prices for medical materials: a multi-country study.

Ide, Hiroo; Mollahaliloglu, Salih

2009-09-01

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

Alaska North Slope crude oil price and the behavior of diesel prices in California

International Nuclear Information System (INIS)

Adrangi, B.; Chatrath, A.; Raffiee, K.; Ripple, R.

2001-01-01

In this paper we analyze the price dynamics of Alaska North Slope crude oil and L.A. diesel fuel prices. We employ VAR methodology and bivariate GARCH model to show that there is a strong evidence of a uni-directional causal relationship between the two prices. The L.A. diesel market is found to bear the majority of the burden of convergence when there is a price spread. This finding may be seen as being consistent with the general consensus that price discovery emanates from the larger, more liquid market where trading volume is concentrated. The contestability of the West Coast crude oil market tends to cause it to react relatively competitively, while the lack of contestability for the West Coast diesel market tends to limit its competitiveness, causing price adjustment to be slow but to follow the price signals of crude oil. Our findings also suggest that the derived demand theory of input pricing may not hold in this case. The Alaska North Slope crude oil price is the driving force in changes of L.A. diesel price

Price setting in turbulent times

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...

Much of the literature on optimal monetary policy uses models in which the degree of nominal price flexibility is exogenous. There are, however, good reasons to suppose that the degree of price flexibility adjusts endogenously to changes in monetary conditions. This article extends the standard new Keynesian model to incorporate an endogenous degree of price flexibility. The model shows that endogenizing the degree of price flexibility tends to shift optimal monetary policy towards complete i...

Firm-specific impacts of CO_2 prices on the stock market value of the Spanish power industry

Pereira da Silva, Patricia; Moreno, Blanca; Figueiredo, Nuno Carvalho

2016-01-01

European Union carbon emissions allowances (EUA) price fluctuations can affect electricity companies' stock market values as these oscillations may change firms' profitability and thus investors' decisions. This outcome can differ not only contingent on the EU ETS Phase, but also on firms' generation mix. Moreover, stock markets may react differently to EUA increases in comparison to decreases, thus asymmetrically. By using daily data from January 2008 to July 2014, this article analyses long-run equilibrium relations and short-run interactions between the aggregated electricity industry stock market returns and EUA price changes. Moreover, we test if the relationship between EUA price variations and electricity stock returns is asymmetric and if the carbon price effect and the asymmetry are power firm-specific. Adding to earlier studies, we initially provide an inspection of the individual impact of EU ETS Phase II and on-going Phase III; followed by a comparative analysis between power firms which core activity relies on renewable energy sources and those whose sources are fundamentally non-renewable ones. A statistically significant positive long-run impact of EU ETS on the aggregated power sector stock market return is found concerning Phase II and works asymmetrically. Moreover, evidence is provided demonstrating that asymmetry and EUA effects are power firm-specific. - Highlights: •EU ETS impacts on stock market returns of Spanish power sector. •Long-run positive effect of EU ETS on market returns is found only in Phase II. •No short-run effects were found. •EUA price effect is company-specific.

Highlights: • ‘Index-based A-MFDFA’ model is proposed to assess the asymmetric multi-fractality. • The asymmetric multi-fractality in the U.S. stock indices are investigated using ‘Index-based’ and ‘Return-based’ A-MFDFA. • The asymmetric feature is more significantly identified by ‘Index-based’ model than ‘return-based’ model. • Source of multi-fractality and time-varying features are analyzed. - Abstract: We detect the asymmetric multi-fractality in the U.S. stock indices based on the asymmetric multi-fractal detrended fluctuation analysis (A-MFDFA). Instead using the conventional return-based approach, we propose the index-based model of A-MFDFA where the trend based on the evolution of stock index rather than stock price return plays a role for evaluating the asymmetric scaling behaviors. The results show that the multi-fractal behaviors of the U.S. stock indices are asymmetric and the index-based model detects the asymmetric multi-fractality better than return-based model. We also discuss the source of multi-fractality and its asymmetry and observe that the multi-fractal asymmetry in the U.S. stock indices has a time-varying feature where the degree of multi-fractality and asymmetry increase during the financial crisis.

Do Canadian electricity prices reflect costs?

International Nuclear Information System (INIS)

Jaccard, M.

1993-01-01

In an article by Cairns and Heyes (1993), it is argued that electricity pricing in Canada diverges from cost due to inter-class rate design that results in cross-subsidies, subsidized cost of capital, intra-class rate design that lacks time-of-use pricing, and failure to collect differential rent. Some problems with the key components of the initial assumption that prices diverge from cost are examined. The premise that inter-class rate design results in cross-subsidies may be correct, but is difficult to test since unregulated crown utilities are not required to make the necessary information public. Cairns and Heyes are on firmer ground in their assertion that provincial government backing of utility debts leads to lower costs of capital than would otherwise occur. Quebec and British Columbia governments have recently undertaken revenue collection initiatives justified under the rationale of addressing this situation. However, there are problems with the assumption that lack of time-of-use pricing indicates cost/price divergence, since such pricing is especially relevant in capacity-critical systems. Most hydroelectric systems are energy-critical and time-of-use differentials are not appropriate. Finally, recent evidence suggests reassessing the differential rent assumptions of the 1980s. The economic rents estimated in that period may be more accurately described as windfall rents existing in the short term while markets adjust to erratic fuel prices and cost changes in nuclear and hydro energy. There may be good economic efficiency arguments against short-term rent collection strategies involving erratic price adjustments. 1 ref

This paper examines the pricing behaviour of the downstream petroleum product market in New Zealand using multivariate error correction models. The unique feature of these models is the use of actual weekly wholesale and retail prices of diesel and unleaded petrol to measure the relative rigidity of domestic prices. The results suggest that price adjustments in domestic markets in response to price changes in world crude oil markets and refined product markets are very weak. Domestic wholesale prices appear to be the key variable in determining retail prices. Lack of competition in the wholesale sector is found to be the main reason for weak price adjustments. (author)

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.

Colombian equity return and narrow money supply: an asymmetric cointegration analysis

Directory of Open Access Journals (Sweden)

Chu V. Nguyen

2012-12-01

Full Text Available The asymmetric, cointegrating relationship between the return on equity market and the narrowly defined money supply is documented. In fact, equity return and the monthly percentage change in the Colombian money supply M1 spread adjusts to the threshold value slower when a contractionary countercyclical policy action or an economic shock causes the money supply M1 to fall relative to the share price index, widening their spread, than when an expansionary countercyclical monetary policy action or a shock causes money supply M1 to move in the opposite direction, narrowing their spread. The empirical findings further indicate the impact lag on the Colombian monetary policy in the equity market is two years. These empirical findings should be of interest to both domestic and international investors who are interested in the Colombian equity market. The results also reveal the presence of both the neoclassical and the post-Keynesian positions on the relationship between equity return and money supply M1 in the Colombian financial market. In the age of globalization, these findings may provide a better understanding of the impact of the countercyclical monetary policy on the equity market in Latin American economies.

The pricing of natural gas in US markets

International Nuclear Information System (INIS)

Brown, S.P.A.; Yucel, M.K.

1993-01-01

Our econometric evidence indicates that changes in natural gas prices are unequal in the long run. Nonetheless, all downstream prices change by at least as much as the average well-head price. Statistically, residential and commercial prices change as much as the city gate price. In the face of persistent shocks, however, market institutions and market dynamics can lead to lengthy periods in which the residential and commercial prices of natural gas adjust less than the wellhead or city gate prices. Electrical and industrial users of natural gas rely heavily on spot supplies and can switch fuels easily. Their ability to switch fuels may be related to the development of a spot market to serve them. Reliance on the spot market may explain why these end users have seen a greater reduction in natural gas prices than have the LDCs over the past seven years. The ability to switch fuels may account for electrical and industrial prices being the source of shocks in their relationships with the wellhead price. It also may explain why prices in these end-sue markets are quick to adjust. Commercial and residential customers cannot switch fuels easily and rely heavily on LDCs for their natural gas. The inability of these end users to switch fuels probably contributes to the reluctance of LDCs to purchase spot supplies of gas. Reliance on contract supplies may explain why the city gate price has not declined as much as electrical and industrial prices of natural gas over the past seven years. Furthermore, the LDCs administer prices in the commercial and residential markets under state regulation

The dynamics of crude oil price differentials

International Nuclear Information System (INIS)

Fattouh, Bassam

2010-01-01

Crude oil price differentials are modelled as a two-regime threshold autoregressive (TAR) process using the method proposed by Caner and Hansen [Caner, M., Hansen, B.E. Threshold autoregression with a unit root. Econometrica 2001; 69; 1555-1596.]. While standard unit root tests suggest that the prices of crude oil of different varieties move closely together such that their price differential is stationary, the TAR results indicate strong evidence of threshold effects in the adjustment process to the long-run equilibrium. These findings suggest that crude oil prices are linked and thus at the very general level, the oil market is 'one great pool' (Adelman, M.A. International oil agreements. The Energy Journal 1984; 5; 1-9.). However, differences in the dynamics of adjustment suggest that within this one pool, oil markets are not necessarily integrated in every time period and hence the dynamics of crude oil price differentials may not follow a stationary process at all times. Although the development of a liquid futures market around the crude oil benchmarks has helped make some distant markets more unified, arbitrage is not costless or risk-free and temporary breakdowns in the benchmarks can lead to decoupling of crude oil prices.

Continuous control of asymmetric forebody vortices in a bi-stable state

Science.gov (United States)

Wang, Qi-te; Cheng, Ke-ming; Gu, Yun-song; Li, Zhuo-qi

2018-02-01

Aiming at the problem of continuous control of asymmetric forebody vortices at a high angle of attack in a bi-stable regime, a dual synthetic jet actuator embedded in an ogive forebody was designed. Alternating unsteady disturbance with varying degree asymmetrical flow fields near the nozzles is generated by adjusting the duty cycle of the drive signal of the actuator, specifically embodying the asymmetric time-averaged pattern of jet velocity, vorticity, and turbulent kinetic energy. Experimental results show that within the range of relatively high angles of attack, including the angle-of-attack region in a bi-stable state, the lateral force of the ogive forebody is continuously controlled by adjusting the duty cycle of the drive signal; the position of the forebody vortices in space, the vorticity magnitude, the total pressure coefficient near the vortex core, and the vortex breakdown location are continuously changed with the duty cycle increased observed from the time-averaged flow field. Instantaneous flow field results indicate that although the forebody vortices are in an unsteady oscillation state, a continuous change in the forebody vortices' oscillation balance position as the duty cycle increases leads to a continuous change in the model's surface pressure distribution and time-averaged lateral force. Different from the traditional control principle, in this study, other different degree asymmetrical states of the forebody vortices except the bi-stable state are obtained using the dual synthetic jet control technology.

The oil price

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.

Cross hedging and forward-contract pricing of electricity

International Nuclear Information System (INIS)

Woo, C.-K.; Hoang, K.; Horowitz, I.

2001-01-01

We consider the problem of an electric-power marketer offering a fixed-price forward contract to provide electricity that it purchases from a potentially volatile and unpredictable fledgling spot energy market. One option for the risk-averse marketer who wants to hedge against the spot-price volatility is to engage in cross hedging to reduce the contract's profit variance, and to determine the forward-contract price as a risk-adjusted price - the sum of a baseline price and a risk premium. We show how the marketer can estimate the spot-price relationship between two wholesale energy markets for the purpose of cross hedging, as well as the optimal hedge and the forward contract's baseline price and risk premium

Appliance Efficiency Standards and Price Discrimination

Spurlock, Cecily Anna [Univ. of California, Berkeley, CA (United States)

2013-05-08

I explore the effects of two simultaneous changes in minimum energy efficiency and ENERGY STAR standards for clothes washers. Adapting the Mussa and Rosen (1978) and Ronnen (1991) second-degree price discrimination model, I demonstrate that clothes washer prices and menus adjusted to the new standards in patterns consistent with a market in which firms had been price discriminating. In particular, I show evidence of discontinuous price drops at the time the standards were imposed, driven largely by mid-low efficiency segments of the market. The price discrimination model predicts this result. On the other hand, in a perfectly competition market, prices should increase for these market segments. Additionally, new models proliferated in the highest efficiency market segment following the standard changes. Finally, I show that firms appeared to use different adaptation strategies at the two instances of the standards changing.

While the literature on price discovery process and information flow between dominant and satellite market is exhaustive, most studies have applied an approach that can be traced back to Hasbrouck (1995) or Gonzalo and Granger (1995). In this paper, however, we propose a Generalized Langevin process with asymmetric double-well potential function, with co-integrated time series and interconnected diffusion processes to model the information flow and price discovery process in two, a dominant and a satellite, interconnected markets. A simulated illustration of the model is also provided.

Oil price and the dollar

Oil prices and the United States (US) dollar exchange rate are driving the evolution of the world economy. This paper investigated long-term relationships between oil prices and the US effective exchange rate. An empirical study was performed on oil prices and the dollar real effective exchange rate between 1974 to 2004. The impact of the dollar exchange rate was also explored, and the effects of oil prices on supply and demand were considered. A dynamic partial equilibrium framework study was evaluated in order to compare how other countries used revenues from oil exports in dollars. The study showed that both variables had similar evolutions when price fluctuations were low. Strong increases in the dollar were associated with lower oil prices. However, adjustment speeds of the dollar real effective exchange rate was slow. Co-integration and causality tests showed that oil prices influenced the exchange rate, and that the link between the 2 variables was transmitted through the country's net foreign asset position. It was concluded that higher oil prices improved US net foreign asset position in relation to other countries, and had a positive impact on dollar appreciation. 24 refs., 6 tabs., 1 fig

Seaweed cultivation has a better advantage over other fisheries activity in terms of easiness on conducting the production and multiplier effect on coastal community welfare. The effect of seaweed farming on the prosperity of coastal community in Southeast Maluku started to take place in 2008, although in 2012 either number of production and workforce is declining rapidly. By solving this problem, this article also provided with identifying and analyzing the supply chain of seaweed cultivation in Southeast Maluku. Based on this analysis we have found that one of the main reasons of declining seaweed production and the number seaweed farmers was asymmetric information that occurred on seaweed supply chain in Southeast Maluku. The component of asymmetric risk was the quality of the seeds, price, information and technology and the knowledge of actual market of seaweed, especially by seaweed farmers. Therefore, it is essential to make a conceptual model on mitigation of asymmetric information on the supply chain of seaweed production. We proposed a conceptual model based on four perspectives, first was goal, criteria and sub-criteria, actor and the solution to mitigate asymmetric information supply chain on seaweed cultivation.

To consume or not. How oil prices affect the comovement of consumption and aggregate wealth

International Nuclear Information System (INIS)

Odusami, Babatunde Olatunji

2010-01-01

This paper provides insight into how oil price movements affect the consumption choices of U.S. households through the wealth channel. Lettau and Ludvigson (2001) show that while consumption, asset wealth, and labor income share a common long-term trend; they substantially deviate from one another in the short run. In this paper, I show that these transitory deviations can be explained by fluctuations in the price of crude oil. Linear and threshold multivariate autoregressive models are used to measure the oil price effect. Oil price effect on the consumption to aggregate wealth ratio is robust to monetary policy effect, sub-period effect, and econometric specifications of oil price effect. Generally speaking, higher (lower) oil price will lead to a decrease (increase) in the proportion of aggregate wealth consumed. In addition, the magnitude of the oil price effect is asymmetric and sub-period dependent. Oil price effect was higher before the 1980's than in succeeding periods. (author)

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.

Cross hedging and forward-contract pricing of electricity

Energy Technology Data Exchange (ETDEWEB)

Woo, C.-K.; Hoang, K. [Energy and Environmental Economics, Inc., 353 Sacramento Street, Suite 1700, 94111 San Francisco, CA (United States); Horowitz, I. [Decision and Information Sciences, Warrington College of Business Administration, University of Florida, 32611 Gainesville, FL (United States)

2001-01-01

We consider the problem of an electric-power marketer offering a fixed-price forward contract to provide electricity that it purchases from a potentially volatile and unpredictable fledgling spot energy market. One option for the risk-averse marketer who wants to hedge against the spot-price volatility is to engage in cross hedging to reduce the contract's profit variance, and to determine the forward-contract price as a risk-adjusted price - the sum of a baseline price and a risk premium. We show how the marketer can estimate the spot-price relationship between two wholesale energy markets for the purpose of cross hedging, as well as the optimal hedge and the forward contract's baseline price and risk premium.

Essays in the Application of Linear and Non-linear Bayesian VAR Models to the Macroeconomic Impacts of Energy Price Shocks

Science.gov (United States)

Nguyen, Bao H.

This thesis is a collection of five self contained empirical macroeconomic papers on the asymmetric effects of energy price shocks on various economies. Chapter 1 formally determines the number of regime changes in the US natural gas market by employing a MS-VAR model. Estimated using Bayesian methods, three regimes are identified for the period 1980 - 2016, namely, before the Decontrol Act, after the Decontrol Act and the Recession. The results show that the natural gas market tends to be much more sensitive to market fundamental shocks occurring in a Recession regime than in the other regimes. Augmenting the model by incorporating the price of crude oil, the results reveal that the impacts of oil price shocks on natural gas prices are relatively small. Chapter 2 provides new empirical evidence on the asymmetric reactions of the U.S. natural gas market and the U.S. economy to its market fundamental shocks in different phases of the business cycle. To this end, we employ a ST-VAR model to capture the asymmetric responses depending on economic conditions. Our results indicate that in contrast to the prediction made by a linear VAR model, the STVAR model provides a plausible explanation to the behavior of the U.S. natural gas market, which asymmetrically reacts in bad times and good times. Chapter 3 examines the relationship between China's economic growth and global oil market fluctuations between 1992Q1 and 2015Q3. We find that: (1) the time varying parameter VAR with stochastic volatility provides a better fit as compared to it's constant counterparts; (2) the impacts of intertemporal global oil price shocks on China's output are often small and temporary in nature; (3) oil supply and specific oil demand shocks generally produce negative movements in China's GDP growth whilst oil demand shocks tend to have positive effects; (4) domestic output shocks have no significant impact on price or quantity movements within the global oil market. Chapter 4 examines the

Price Elasticity of Alcohol Demand in India.

Kumar, Santosh

2017-05-01

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

Investors’ risk attitudes and stock price fluctuation asymmetry

Science.gov (United States)

Zhang, Yu; Li, Honggang

2011-05-01

Price rise/fall asymmetry, which indicates enduring but modest rises and sudden short-term falls, is a ubiquitous phenomenon in stock markets throughout the world. Instead of the widely used time series method, we adopt inverse statistics from turbulence to analyze this asymmetry. To explore its underlying mechanism, we build a multi-agent model with two kinds of investors, which are specifically referred to as fundamentalists and chartists. Inspired by Kahneman and Tversky’s claim regarding peoples’ asymmetric psychological responses to the equivalent levels of gains and losses, we assume that investors take different risk attitudes to gains and losses and adopt different trading strategies. The simulation results of the model developed herein are consistent with empirical work, which may support our conjecture that investors’ asymmetric risk attitudes might be one origin of rise/fall asymmetry.

2010-07-01

Full Text Available This paper studies inventory and pricing policies in a non-cooperative supply chain with onesupplier and several retailers who are involved in producing, delivering and selling a singleproduct. We consider inventory policies in an information-asymmetric vendor managedinventory. The study consists of different scenarios where a supplier produces the product at thewholesale price to multiple retailers. The retailers also distribute the product in dispersed andindependent markets at retail selling prices. The demand rate for each market is a nondecreasingconcave function of the marketing expenditures of both local retailers and themanufacturer, but a non-increasing and convex function of the retail selling prices. The primarypurpose is to determine wholesale price, marketing expenditure for supplier and retailers,replenishment cycles for the product, and backorder quantity to maximize the total profit forboth groups of supplier and retailers. All scenarios are modeled as a Stackelberg game wherethe manufacturer is the leader and the retailers are the followers. A numerical study arepresented to demonstrate the influences of decision variables and/or parameters in variousscenarios.

Thompson, Kara; Stockwell, Tim; Wettlaufer, Ashley; Giesbrecht, Norman; Thomas, Gerald

2017-02-01

There is an interest globally in using Minimum Unit Pricing (MUP) of alcohol to promote public health. Canada is the only country to have both implemented and evaluated some forms of minimum alcohol prices, albeit in ways that fall short of MUP. To inform these international debates, we describe the degree to which minimum alcohol prices in Canada meet recommended criteria for being an effective public health policy. We collected data on the implementation of minimum pricing with respect to (1) breadth of application, (2) indexation to inflation and (3) adjustments for alcohol content. Some jurisdictions have implemented recommended practices with respect to minimum prices; however, the full harm reduction potential of minimum pricing is not fully realised due to incomplete implementation. Key concerns include the following: (1) the exclusion of minimum prices for several beverage categories, (2) minimum prices below the recommended minima and (3) prices are not regularly adjusted for inflation or alcohol content. We provide recommendations for best practices when implementing minimum pricing policy.

The Economic Impact of Government Policy on Market Prices of Low-Fat Pork in South Korea: A Quasi-Experimental Hedonic Price Approach

Directory of Open Access Journals (Sweden)

Hyun No Kim

2018-03-01

Full Text Available The implementation of government policy can have an influence on market environment and market prices of pork in consequence. In South Korea, consumers prefer high-fat pork cuts due to the prevalence of roosting pork over a hot grill. This paper examines the impact of the government policy which aims to increase the consumption of low-fat pork cuts because of the concerns regarding asymmetric consumption between high-fat and low-fat pork cuts. Using hedonic price methods combined with quasi-experimental approaches we estimate the subsequent impact of food policy on the price of low-fat pork cuts using a time series of sales data. This study utilized an effective approach which has been widely employed for policy evaluation to produce plausible estimates of the economic values generated by the government policy. We find the existence of market segmentation and different impacts of the policy between markets. While the market price for high-fat pork cuts has remained stable, the price for low-fat pork cuts has slightly increased since the policy has been implemented. This paper illustrates that government’s policy can be a good strategy to maintain sustainability of the food industry by improving the balance in pork consumption and the management of stocks.

2017-03-20

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. 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.

Canadian natural gas market dynamics and pricing : an update

International Nuclear Information System (INIS)

2002-10-01

This energy market assessment (EMA) report discusses natural gas price formation and describes the current functioning of regional gas markets in Canada. This EMA also describes the factors affecting the price of natural gas in Canada and examines natural gas markets on a region-by region basis. It is shown that as part of an integrated North American market, prices of natural gas in Canada reflect supply and demand factors in both Canada and the United States. During the low oil price period of 1997/1998, high demand for natural gas outpaced the supply because of low drilling and production activity by producers. In response to the increased demand and lower levels of supply, the price of natural gas increased significantly in 1999 and 2000. This was followed by a period of market adjustment. The importance of electronic trading systems for enhancing price discovery was also discussed with reference to how spot and futures markets allow market participants to manage price volatility. It was determined that Canadians have had access to natural gas on terms and conditions equal to export customers, and at equal pricing. In early November 2000, natural gas prices in North American began to rise due to low levels of natural gas in storage. The price shocks were felt unevenly across the North American market. In response to the high prices, consumers conserved energy use, and many industrial users switched to cheaper fuels. By the spring 2001, demand continued to decrease at a time when production was high. These factors contributed to the downward pressure on gas prices. This EMA discusses the structure of market transactions and market adjustment mechanisms. It is presented in the context of the approaching 2002/2003 winter season where the tightening between natural gas supply and demand is expected to result in price volatility. 28 figs

Rationales for capacity remuneration mechanisms: Security of supply externalities and asymmetric investment incentives

International Nuclear Information System (INIS)

Keppler, Jan Horst

2017-01-01

Economics so far provides little conceptual guidance on capacity remuneration mechanisms (CRM) in deregulated electricity markets. Ubiquitous in real-world electricity markets, CRMs are introduced country by country in an ad hoc manner, lacking the theoretical legitimacy and the conceptual coherence enabling comparability and coordination. They are eyed with suspicion by a profession wedded to a theoretical benchmark model that argues that competitive energy-only markets with VOLL pricing provide adequate levels of capacity. While the benchmark model is a consistent starting point for discussions about electricity market design, it ignores the two market failures that make CRMs the practically appropriate and theoretically justified policy response to capacity issues. First, energy-only markets fail to internalize security-of-supply externalities as involuntary curbs on demand under scarcity pricing generate social costs beyond the private non-consumption of electricity. Second, when demand is inelastic and the potential capacity additions are discretely sized, investors face asymmetric incentives and will underinvest at the margin rather than overinvest. After presenting the key features of the theoretical benchmark model, this paper conceptualizes security of supply externalities and asymmetric investment incentives and concludes with some consideration regarding design of CRMs. - Highlights: • Capacity remuneration mechanisms are ubiquitous in real-world electricity markets. • Theory claims that energy-only markets can provide optimal capacity on their own. • However theory fails to account for two types of market failures. • Involuntary demand curbs under VOLL-pricing create security-of-supply externalities. • With inelastic demand, discretely sized capacity options lead to underinvestment.

Dynamic Pricing in Electronic Commerce Using Neural Network

Science.gov (United States)

Ghose, Tapu Kumar; Tran, Thomas T.

In this paper, we propose an approach where feed-forward neural network is used for dynamically calculating a competitive price of a product in order to maximize sellers’ revenue. In the approach we considered that along with product price other attributes such as product quality, delivery time, after sales service and seller’s reputation contribute in consumers purchase decision. We showed that once the sellers, by using their limited prior knowledge, set an initial price of a product our model adjusts the price automatically with the help of neural network so that sellers’ revenue is maximized.

Heterogeneous Investors, Negotiation Strength & Asset Prices in Private Markets: Evidence from Commercial Real Estate

Directory of Open Access Journals (Sweden)

2013-08-01

Full Text Available We examine the impact of heterogeneous investors with asymmetric bargaining positions on transaction prices in private commercial real estate markets. Using a dataset that contains nearly 100,000 commercial real estate transactions during 1997-2009, we examine the extent to which common conditions of sale and buyer characteristics affect bargaining power and negotiated prices. We find that tax-motivated buyers seeking to complete a delayed Section 1031 exchange pay an average price premium of 12.5% when purchasing smaller properties. However, these price premiums for exchange motivated buyers are not observed among more expensive properties. We find strong evidence that out-of-state buyers pay significantly more (8 - 11% premium for commercial properties than in-state buyers. Consistent with our expectations, we find that sellers of distressed properties negotiate significantly lower transaction prices (13 - 15% discount than sellers of non-distressed properties, all else equal. Finally, we find evidence that REITs pay price premiums between 14 - 16% for office and industrial and retail properties. Our results strongly support the notion that relative bargaining power influences negotiated transaction prices.

Endogenous Market-Clearing Prices and Reference Point Adaptation

Science.gov (United States)

Dragicevic, Arnaud Z.

When prices depend on the submitted bids, i.e. with endogenous market-clearing prices in repeated-round auction mechanisms, the assumption of independent private values that underlines the property of incentive-compatibility is to be brought into question; even if these mechanisms provide active involvement and market learning. In its orthodox view, adaptive bidding behavior imperils incentive-compatibility. We relax the assumption of private values' independence in the repeated-round auctions, when the market-clearing prices are made public at the end of each round. Instead of using game-theory learning models, we introduce a behavioral model that shows that bidders bid according to the anchoring-and-adjustment heuristic, which neither ignores the rationality and incentive-compatibility constraints, nor rejects the posted prices issued from others' bids. Bidders simply weight information at their disposal and adjust their discovered value using reference points encoded in the sequential price weighting function. Our model says that bidders and offerers are sincere boundedly rational utility maximizers. It lies between evolutionary dynamics and adaptive heuristics and we model the concept of inertia as high weighting of the anchor, which stands for truthful bidding and high regard to freshly discovered preferences. Adjustment means adaptive rule based on adaptation of the reference point in the direction of the posted price. It helps a bidder to maximize her expected payoff, which is after all the only purpose that matters to rationality. The two components simply suggest that sincere bidders are boundedly rational. Furthermore, by deviating from their anchor in the direction of the public signal, bidders operate in a correlated equilibrium. The correlation between bids comes from the commonly observed history of play and each bidder's actions are determined by the history. Bidders are sincere if they have limited memory and confine their reference point adaptation

On the Impact of Policy Uncertainty on Oil Prices: An Asymmetry Analysis

Directory of Open Access Journals (Sweden)

Mohsen Bahmani-Oskooee

2018-01-01

Full Text Available Previous research has assessed the impact of policy uncertainty on a few macro variables. In this paper, we consider its impact on oil prices. Oil prices are usually determined in global markets by the law of demand and supply. Our concern in this paper is to determine which country’s policy uncertainty measure has an impact on oil prices. Using both the linear and the nonlinear Autoregressive Distributed Lag (ARDL methods, we find that while policy uncertainty measures of Canada, China, Europe, Japan, Russia, South Korea, and the U.S. have short-run effects, short-run effects last into the long-run asymmetric effects only in the case of China. This may reflect the importance and recent surge in China’s engagement in world trade.

Mattingly, T Joseph; Levy, Joseph F; Slejko, Julia F; Onwudiwe, Nneka C; Perfetto, Eleanor M

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.

THE RELATIONSHIP BETWEEN SCARCITY OF NATURAL RESOURCES AND THEIR REAL PRICES

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

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

2013-01-01

The paper explores the extent to which products follow systematic pricing patterns over their life cycle and the impact this has on the measurement of inflation. Using a large US scanner data set on supermarket products and applying exible regression methods, we find that on average prices decline as items age. This life cycle price change is often attributed to quality difference in the construction of CPI as items are replaced due to disappearance and at sample rotations. This introduces a ...

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.

Flex cars and the alcohol price

International Nuclear Information System (INIS)

Ferreira, Alex Luiz; Da Silveira, Jaylson Jair; De Almeida Prado, Fernando Pigeard

2009-01-01

We build a model that incorporates the effect of the innovative 'flex' car, an automobile that is able to run with either gasoline or alcohol, on the dynamics of fuel prices in Brazil. Our model shows that differences regarding fuel prices will now depend on the proportions of alcohol, gasoline and flex cars in the total stock. Conversely, the demand for each type of car will also depend on the expected future prices of alcohol and gasoline (in addition to the car prices). The model reflects our findings that energy prices are tied in the long run and that causality runs stronger from gasoline to alcohol. The estimated error correction parameter is stable, implying that the speed of adjustment towards equilibrium remains unchanged. The latter result is probably due to a still small fraction of flex cars in the total stock (approx. 5%), despite the fact that its sales nearly reached 100% in 2006. (author)

Dynamics of heating oil market prices in Europe

International Nuclear Information System (INIS)

Indjehagopian, J.P.; Lantz, F.; Simon, V.

2000-01-01

This paper concerns the German and French heating oil market and attempts to establish long- and short-term relationships between German and French monthly heating oil prices in dollars, the Rotterdam spot price for the same product and the DM/US$ and FF/US$ exchange rates during the period from January 1987 to December 1997. To model the market over the period under consideration, incorporating the Gulf War, we have used conventional unit root tests and sequential tests allowing structural changes. Long-term relationships, with shifts in regime detected by cointegration tests taking structural breaks into consideration, are estimated. The short-term dynamics defined by a vector error correction (VEC) mechanism is derived in a classic manner when in presence of a cointegrated VAR system. The econometric results obtained are commented on from an economic point of view. Weak exogeneity tests are performed and the conditional VEC model is deduced, enabling measurement of the instantaneous impact of variations in weakly exogenous exchange rates on variations in heating oil prices in Germany and France. Lastly, a study is made of the asymmetric reaction of domestic prices to positive and negative variations in exchange rates and the Rotterdam spot quotation. 25 refs

Energy price uncertainty, energy intensity and firm investment

International Nuclear Information System (INIS)

Yoon, Kyung Hwan; Ratti, Ronald A.

2011-01-01

This paper examines the effect of energy price uncertainty on firm-level investment. An error correction model of capital stock adjustment is estimated with data on U.S. manufacturing firms. Higher energy price uncertainty is found to make firms more cautious by reducing the responsiveness of investment to sales growth. The result is robust to consideration of energy intensity by industry. The effect is greater for high growth firms. It must be emphasized that the direct effect of uncertainty is not estimated. Conditional variance of energy price is obtained from a GARCH model. Findings suggest that stability in energy prices would be conducive to greater stability in firm-level investment. (author)

Brazilian Alcohol Program (Proalcool): economic re-evaluation and demand adjustments

Motta, R.S. da; Rocha Ferreira, L. da

1987-01-01

The aim of this paper is to discuss the economic impact on the Brazilian National Alcohol Programme caused by changes in the energy scenery, in view of recent oil price fall in the international market, and evaluate the necessary adjustments of the Programme according to the new Brazilian economic reality. The economic analysis concludes that the alcohol production, considering current production capacity and its investments, could be economically feasible at international oil prices near US$ 30.00. Excluding investments, its feasibility would be between US$ 18.00 and US$ 20.00 per equivalent oil barrel. Based on these conclusions, proposals for adjusting the PROALCOOL are discussed, including alternative pricing, fiscal and credit policies to control the alcohol-fuel demand. (author)

Implications for Firms with Limited Information to Take Advantage of Reference Price Effect in Competitive Settings

Directory of Open Access Journals (Sweden)

Junhai Ma

2017-01-01

Full Text Available This paper studies internal reference price effects when competitive firms face reference price effects and make decisions based on partial information, where their decision-making mechanism is modeled by a dynamic adjustment process. It is shown that the evolution of this dynamic adjustment goes to stabilization if both adjustment speeds are small and the complexity of this evolution increases in adjustment speeds. It is proved that the necessary condition for flip bifurcation or Neimark-Sacker bifurcation will occur with the increase of adjustment speed in two special cases. What is more, numerical simulations show that these bifurcations do occur. Then, the impacts of parameters on stability and profits are investigated and some management insights for firms with limited information to take advantage of reference price effects are provided.

The taxation effect on gasoline price asymmetry nexus: Evidence from both sides of the Atlantic

International Nuclear Information System (INIS)

Polemis, Michael L.; Fotis, Panagiotis N.

2014-01-01

This paper explores the degree of competition in various gasoline markets and infers possible causes of price asymmetry across the globe. For this purpose we use the Dynamic Ordinary Least Square method in order to estimate price asymmetry in twelve European countries and the United States for a sample of weekly observations which spans the period from June 1996 to August 2011. The results indicate the common perception that less competitive gasoline markets exhibit price asymmetry, while highly competitive gasoline markets follow a symmetric price adjustment path. Finally, the inclusion of taxes (VAT and excise tax) into retail gasoline prices, supports the existence of price asymmetry in many European countries. - Highlights: • We examine the possible causes of gasoline price asymmetry across the globe. • We investigate the effect of taxation on the retail gasoline price adjustments. • There is a symmetric gasoline price response in the EU wholesale level. • Less competitive gasoline markets exhibit price asymmetry. • The oligopolistic structure of the gasoline markets inflates price asymmetry

Adjusting Health Expenditures for Inflation: A Review of Measures for Health Services Research in the United States.

Dunn, Abe; Grosse, Scott D; Zuvekas, Samuel H

2018-02-01

To provide guidance on selecting the most appropriate price index for adjusting health expenditures or costs for inflation. Major price index series produced by federal statistical agencies. We compare the key characteristics of each index and develop suggestions on specific indexes to use in many common situations and general guidance in others. Price series and methodological documentation were downloaded from federal websites and supplemented with literature scans. The gross domestic product implicit price deflator or the overall Personal Consumption Expenditures (PCE) index is preferable to the Consumer Price Index (CPI-U) to adjust for general inflation, in most cases. The Personal Health Care (PHC) index or the PCE health-by-function index is generally preferred to adjust total medical expenditures for inflation. The CPI medical care index is preferred for the adjustment of consumer out-of-pocket expenditures for inflation. A new, experimental disease-specific Medical Care Expenditure Index is now available to adjust payments for disease treatment episodes. There is no single gold standard for adjusting health expenditures for inflation. Our discussion of best practices can help researchers select the index best suited to their study. © Published 2016.

Impact of oil price shocks on selected macroeconomic variables in Nigeria

International Nuclear Information System (INIS)

Iwayemi, Akin; Fowowe, Babajide

2011-01-01

The impact of oil price shocks on the macroeconomy has received a great deal of attention since the 1970 s. Initially, many empirical studies found a significant negative effect between oil price shocks and GDP but more recently, empirical studies have reported an insignificant relationship between oil shocks and the macroeconomy. A key feature of existing research is that it applies predominantly to advanced, oil-importing countries. For oil-exporting countries, different conclusions are expected but this can only be ascertained empirically. This study conducts an empirical analysis of the effects of oil price shocks on a developing country oil-exporter - Nigeria. Our findings showed that oil price shocks do not have a major impact on most macroeconomic variables in Nigeria. The results of the Granger-causality tests, impulse response functions, and variance decomposition analysis all showed that different measures of linear and positive oil shocks have not caused output, government expenditure, inflation, and the real exchange rate. The tests support the existence of asymmetric effects of oil price shocks because we find that negative oil shocks significantly cause output and the real exchange rate. (author)

Petroleum products price regulation in Nov Scotia : a six-month review

International Nuclear Information System (INIS)

2007-03-01

Gasoline pricing regulation was introduced in July 2006 in order to achieve the following 3 main objectives: (1) stabilize prices by reducing the frequency of price changes and creating more uniform pricing across the province, (2) maintain industry infrastructure by slowing or halting the decline in the dealer network, particularly in rural areas, by improving viability through regulated margins, and (3) minimize the cost to consumers since higher prices are expected to result from the actions needed to maintain price stability and the higher margins needed to maintain industry infrastructure. This report examined the extent to which these objectives were achieved and contained the findings and recommendations of a review of the first six months of gasoline price regulation in Nova Scotia. The report discussed the rationale for regulation, study objectives, approach, and warning signs. It also discussed gasoline regulation in Nova Scotia including how regulation works and implementing regulation. The Nova Scotia gasoline market was presented with reference to industry structure; pre-regulation competition and pricing; and how regulation may affect structure and competition. Last, the report discussed whether regulation was meeting the objectives and perspectives on regulation. Several recommendations were presented, such as reducing the benchmark price adjustment period from two weeks to one week; removing the price cap on full-serve gasoline; adopting a fixed and transparent formula for forward averaging and applying it at each adjustment; and considering a framework for regulatory review. 12 refs., 15 figs

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.

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.

Natural gas pricing policies in Southeast Asia

International Nuclear Information System (INIS)

Pacudan, R.B.

1998-01-01

The very dynamic economies of Southeast Asia have recently been experiencing a rapid increase in energy demand. Parallel to this development, there has been an increase in the utilization of indigenous natural gas resources. This article reviews gas-pricing policies in the region, which partly explain the rise in gas utilization. Although diverse, energy pricing policies in Southeast Asia address the common objective of enhancing domestic gas production and utilization. The article concludes that a more rational gas-pricing policy framework is emerging in the region. In global terms, gas pricing in the region tends to converge in a market-related framework, despite the many different pricing objectives of individual countries, and the predominance of non-economic pricing objectives in certain countries (especially gas-rich nations). Specifically, governments have been flexible enough to follow global trends and initiate changes in contractual agreements (pricing and profit-sharing), giving oil companies more favourable terms, and encouraging continued private investment in gas development. At the same time, promotional pricing has also been used to increase utilization of gas, through set prices and adjusted taxes achieving a lower price level compared to substitute fuels. For an efficient gas-pricing mechanism, refinements in the pricing framework should be undertaken, as demand for gas approaches existing and/or forecast production capacities. (author)

2016-12-01

Full Text Available In this paper, we constructed a theoretical model of strategic pricing behavior of the players in a Polish wholesale fuel market. This model is consistent with the characteristics of the industry, the wholesale market, and the players. The model is based on the standard methodology of repeated games with a built-in adjustment to a focal price, which resembles the Import Parity Pricing (IPP mechanism. From the equilibrium of the game, we conclude that the focal price policy implies a parallel pricing strategic behavior on the market.

This paper analyses the distribution of benefits between firms and consumers due to the price regulation of the Spanish energy sectors (electricity, oil fuels and gas) during the decade 1987-1997. To that effect, we compare the actual evolution of energy prices with alternate benchmarks in order to assess the potential existence of a pro-industry or a pro-consumer bias in the pricing policies followed by the regulator. Our results show a pro-industry-biased regulatory context, where consumers benefited very little from price control. The successive price adjustments over time allowed the companies to keep all the productivity gains and cost reductions and to increase their profitability rates relative to those achieved in the manufacturing sector.

Crude oil pricing in Asia and future problems; Asia no gen`yu pricing to kongo no kadai

Energy Technology Data Exchange (ETDEWEB)

Kato, T. [The Institute of Energy Economics, Tokyo (Japan)

1997-01-30

This paper describes pricing factors of crude oil for Asia and future problems. Price of the Middle East crude oil for Asia is determined by linking the spot price of Dubayy crude oil using as a marker. Factors affecting the pricing of marker crude oil include the information dispatching functions for prices of spot market and paper market of marker crude oil, the presence of competitive crude oil, and the correlation between market of oil products and price of crude oil. The paper market of Dubayy crude oil with a small scale of trading provides poor impact and transparency. In Asia, there is no strong competitive crude oil except the Middle East crude oil. There is only a weak price linking between crude oil and products. These are the background that the price of Middle East crude oil stays at the high level and the price adjusting functions are hard to work. The marker crude oil should be changed to another except Dubayy crude oil, and information should be dispatched from purchasers based on the stable standard crude oil. The real paper market should be created, and the force of speaking to oil producing countries should be enhanced by concentrating forces of major oil consuming countries in Asia. It is necessary to find out competitive crude oils. 5 figs., 6 tabs.

Oil price shocks and stock markets in the U.S. and 13 European countries

International Nuclear Information System (INIS)

Park, Jungwook; Ratti, Ronald A.

2008-01-01

Oil price shocks have a statistically significant impact on real stock returns contemporaneously and/or within the following month in the U.S. and 13 European countries over 1986:1-2005:12. Norway as an oil exporter shows a statistically significantly positive response of real stock returns to an oil price increase. The median result from variance decomposition analysis is that oil price shocks account for a statistically significant 6% of the volatility in real stock returns. For many European countries, but not for the U.S., increased volatility of oil prices significantly depresses real stock returns. The contribution of oil price shocks to variability in real stock returns in the U.S. and most other countries is greater than that of interest rate. An increase in real oil price is associated with a significant increase in the short-term interest rate in the U.S. and eight out of 13 European countries within one or two months. Counter to findings for the U.S. and for Norway, there is little evidence of asymmetric effects on real stock returns of positive and negative oil price shocks for oil importing European countries.

Extended dynamic oligopolies with flexible workforce and isoelastic price function

Directory of Open Access Journals (Sweden)

Akio Matsumoto

2016-11-01

Full Text Available Single-product oligopolies without product differentiation are examined with linear production, production adjustment, flexible workforce and investment costs. The price function is assumed to be hyperbolic which makes the nonlinearity of the model much stronger than in the case of linear price function examined earlier in the literature. The best responses of the firms are determined which are not monotonic in contrast to the linear case. The set of all steady states is then characterized and in the case of a duopoly it is illustrated. The asymptotical behavior of the steady states is examined by using simulation. We analyze the effects of such costs on the industry dynamics and compare them to the prediction by the well known model with hyperbolic price function and no product adjustment and investments costs.

Full Text Available The article is focused on price transmission within milk commodity chain in the Czech Republic. The article distinct on milk products with low value added – cow milk/paper box milk and products with higher value added – cow milk/butter. Price transmission is measured by the coefficient of elasticity of the price transmission (EPT; price transfer is examined in demand as well as supply direction. Next part of the analysis measures price differences (by coefficient determination – R2 in supply direction. Last step in this analysis is the impact of time delay at the price transmission process (measured by R2. The price transmission is asymmetric in the supply direction on both parts of commodity chain (EPT = 0.29 and 0.62, in the demand direction is more symmetric (EPT = 0.31 and 1.02. The assumption of better transfer of positive price changes was confirmed. At the commodity chain of milk/dairy products the time delay is not so much important. With both tested commodity chains there was found higher power of downstream markets, proving demand driven behaviour of these commodity chains, and there was detected oligopsony market structure as well. The data represent monthly prices on both chosen vertical levels in the period of 1/2000–8/2013.

Davidson, C.; James, T. L.; Margolis, R.; Fu, R.; Feldman, D.

2014-10-01

The price of photovoltaic (PV) systems in the United States (i.e., the cost to the system owner) has dropped precipitously in recent years, led by substantial reductions in global PV module prices. This report provides a Q4 2013 update for residential PV systems, based on an objective methodology that closely approximates the book value of a PV system. Several cases are benchmarked to represent common variation in business models, labor rates, and module choice. We estimate a weighted-average cash purchase price of $3.29/W for modeled standard-efficiency, polycrystalline-silicon residential PV systems installed in the United States. This is a 46% decline from the 2013-dollar-adjusted price reported in the Q4 2010 benchmark report. In addition, this report frames the cash purchase price in the context of key price metrics relevant to the continually evolving landscape of third-party-owned PV systems by benchmarking the minimum sustainable lease price and the fair market value of residential PV systems.

Chen, Cong; Xu, Zhi-wei; Wang, Meng; Chen, Hai-yan

2014-11-01

A novel dual-wavelength fiber laser with asymmetric fiber Bragg grating (FBG) Fabry-Perot (FP) cavity is proposed and experimentally demonstrated. A couple of uniform FBGs are used as the cavity mirrors, and the third FBG is used as intracavity wavelength selector by changing its operation temperature. Experimental results show that by adjusting the operation temperature of the intracavity wavelength selector, a tunable dual-wavelength laser emission can be achieved. The results demonstrate the new concept of dual-wavelength lasing with asymmetric FBG FP resonator and its technical feasibility.

This paper looks into natural gas pricing in the post-financial crisis market and, in particular, examines the question whether the oil-linked gas pricing system has outlived its utility as global gas markets mature and converge more rapidly than expected and as large new resources of unconventional gas shift the gas terms-of-trade. Two opposing natural gas pricing systems have coexisted for the last two decades. On the one hand, there is traditional oil-linked pricing, used in pipeline gas imports by Continental European countries and in LNG imports by the countries in Far East. The other is the system led by futures exchanges in deregulated, competitive markets largely in the UK and the US. World gas markets are changing and the basis and mechanisms of price formation are changing with them. There is no reason to expect a revolution in gas pricing, but formulas designed to address the challenges of the 1970's will need to adjust to the realities of the present and expectations for the 21. century. Because such changes will imply a redistribution of costs and benefits, vested shareholders will defend the status quo. But hopefully and ultimately, appropriately regulated markets will assert themselves and shareholders along the entire value chain will have their interests served

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

Directory of Open Access Journals (Sweden)

2015-10-01

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

Cuba's transition to market-based energy prices

International Nuclear Information System (INIS)

Perez-Lopez, J.F.

1992-01-01

Since 1960 the Soviet Union has been, for all practical purposes, Cuba's exclusive supplier of energy products. For certain time periods, Soviet sales of oil and oil products to Cuba were made at concessional prices; prior to 1991, they were priced using transferable rubles and were essentially bartered for Cuban goods, especially sugar. Effective January 1, 1991, the Soviet Union shifted to world market prices and convertible currency payments for all traded commodities, including energy products. The shift to market prices and convertible currencies in Cuban-Soviet energy trade has already brought - or is likely to bring - a number of adjustments in four areas: (1) the trade balance; (2) the ability to reexport oil and oil products; (3) energy consumption patterns; (4) and the structure of energy supplies. 33 refs., 8 tabs

Strategies for OPEC's pricing decisions. [Using model of world energy market

Energy Technology Data Exchange (ETDEWEB)

Gately, D; Kyle, J F; Fischer, D

1977-11-01

A model of the world energy market that incorporates price expectations and lagged adjustments of demand and supply is used to examine implications of various price-paths that could be selected by OPEC. After demonstrating the sensitivity of the results to changes in functional specifications and certain parameter values, the authors discuss a variety of rule-of-thumb pricing strategies under which OPEC sets prices in response to available market signals. A strategy that is relatively cautious about further major price increases serves OPEC relatively well in comparison with other stategies, but there exists a real possibility of major, abrupt price increases within the next ten years.

An EV Charging Scheduling Mechanism Based on Price Negotiation

Directory of Open Access Journals (Sweden)

Baocheng Wang

2018-05-01

Full Text Available Scheduling EV user’s charging behavior based on charging price and applying renewable energy resources are the effective methods to release the load pressure of power grids brought about by the large-scale popularity of electric vehicles (EVs. This paper presents a novel approach for EV charging scheduling based on price negotiation. Firstly, the EV charging system framework based on price negotiation and renewable energy resources is discussed. Secondly, the price negotiation model is presented, including the initial price models and the conditions of transactions. Finally, an EV charging scheduling mechanism based on price negotiation (CSM-PN, including the price adjustment strategies of both the operator and EV users is proposed to seek a final transaction during multi-round price negotiation. Simulation results show that this novel approach can effectively improve the charging station operator’s income, reduce the EV users’ costs, and balance the load of the power grid while improving the efficiency of the EV charging system.

This study models the bid-ask spread in financial markets as a function of asset price variability and order flow. The market-maker is characterized as passively accepting orders to buy and to sell a security at the market's prevailing price (plus or minus half the bid-ask spread). The bid-ask spread adjusts to cover market-makers' average costs. The bid-ask spread then varies positively with: the security's price volatility, the volatility of order flow, and the absolute value of the market-...

Transfer Pricing Documentation - A Current Issue

Directory of Open Access Journals (Sweden)

Violeta Isai

2016-07-01

Full Text Available Rather quick development of the business environment has led to the implementation of legislative measures to meet the requirements and amendments thereto. With the adoption of the Fiscal Procedure Code and Order no. 442/2016 were founded transfer pricing procedures, denoting a means of making taxable transfer of a high tax country to a low tax country. These laws have laid down conditions that must be met and materiality thresholds that must take into account the taxpayer to draft transfer pricing documentation file. The aim of these measures is to reduce the differences between the prices charged by the related parts and the market value and also to actual results of company taxation. The tax authorities are entitled to apply price adjustments when it is not the principle of market value, which entail economic double taxation. Application and dossier preparation of transfer pricing contribute to a collective vision on the market in which the company operates, understanding how business development and, not least, the creation of an appropriate fiscal planning.

Achieving high value care for all and the perverse incentives of 340B price agreements.

Science.gov (United States)

Whittington, Melanie D; Campbell, Jonathan D; McQueen, R Brett

2018-04-01

Section 340B of the Public Health Service Act requires drug manufacturers to enter into price agreements with the Department of Health and Human Services. These agreements result in variation in the price paid to acquire a drug by sector, which complicates the price used in cost-effectiveness analyses. We describe the transactions and sectors in a 340B agreement using a multiple sclerosis drug. Cost-effectiveness estimates were calculated for the drug using drug prices from the manufacturer and payer perspective. We found the amount paid to the manufacturer (340B price) was a good value ($118,256 per quality-adjusted life-year); however, from the payer drug cost perspective, good value ($196,683 per quality-adjusted life-year) was not achieved. Given that emerging value frameworks incorporate cost-effectiveness, these price variations may have downstream negative consequences, including inaccurate coverage and reimbursement policy recommendations. Upcoming policy changes to the 340B program should incentivize pricing schemes hinged on transparency and value.

Electricity prices and fuel costs. Long-run relations and short-run dynamics

2009-01-01

The paper examines the long-run relation and short-run dynamics between electricity prices and three fossil fuel prices - coal, natural gas and crude oil - using annual data for the U.S. for 1960-2007. The results suggest (1) a stable long-run relation between real prices for electricity and coal (2) Bi-directional long-run causality between coal and electricity prices. (3) Insignificant long-run relations between electricity and crude oil and/or natural gas prices. And (4) no evidence of asymmetries in the adjustment of electricity prices to deviations from equilibrium. A number of implications are addressed. (author)

The Connection Between House Price Appreciation and Property Tax Revenues*

OpenAIRE

Lutz, Byron F.

2008-01-01

This paper explores two aspects of the connection between property tax revenues and house prices. First, I estimate the elasticity of property tax revenues with respect to house prices. This elasticity does not necessarily equal one as governments may adjust effective tax rates to offset changes in property values. Second, I examine the timing of the relationship. Institutional features of the property tax make it unlikely that changes in house prices will immediately influence tax revenues. ...

Stochastic resonance and MFPT in an asymmetric bistable system driven by correlated multiplicative colored noise and additive white noise

Science.gov (United States)

Shi, Pei-Ming; Li, Qun; Han, Dong-Ying

2017-06-01

This paper investigates a new asymmetric bistable model driven by correlated multiplicative colored noise and additive white noise. The mean first-passage time (MFPT) and the signal-to-noise ratio (SNR) as the indexes of evaluating the model are researched. Based on the two-state theory and the adiabatic approximation theory, the expressions of MFPT and SNR have been obtained for the asymmetric bistable system driven by a periodic signal, correlated multiplicative colored noise and additive noise. Simulation results show that it is easier to generate stochastic resonance (SR) to adjust the intensity of correlation strength λ. Meanwhile, the decrease of asymmetric coefficient r2 and the increase of noise intensity are beneficial to realize the transition between the two steady states in the system. At the same time, the twice SR phenomena can be observed by adjusting additive white noise and correlation strength. The influence of asymmetry of potential function on the MFPTs in two different directions is different.

Taking the mystery out of gasoline prices

International Nuclear Information System (INIS)

Anon.

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

State energy price and expenditure report, 1995

Energy Technology Data Exchange (ETDEWEB)

NONE

1998-08-01

The State Energy Price and Expenditure Report (SEPER) presents energy price and expenditure estimates individually for the 50 States and the District of Columbia and in aggregate for the US. The estimates developed in the State Energy Price and Expenditure Data System (SEPEDS) are provided by energy source and economic sector and are published for the years 1970 through 1995. Data for all years are available on a CD-ROM and via Internet. Consumption estimates used to calculate expenditures and the documentation for those estimates are taken from the State Energy Data Report 1995, Consumption Estimates (SEDR), published in December 1997. Expenditures are calculated by multiplying the price estimates by the consumption estimates, which are adjusted to remove process fuel; intermediate petroleum products; and other consumption that has no direct fuel costs, i.e., hydroelectric, geothermal, wind, solar, and photovoltaic energy sources.

Obesity and supermarket access: proximity or price?

Science.gov (United States)

Drewnowski, Adam; Aggarwal, Anju; Hurvitz, Philip M; Monsivais, Pablo; Moudon, Anne V

2012-08-01

We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk=0.34; 95% confidence interval=0.19, 0.63) Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.

In individual companies, price is one significant factor in achieving marketing success. In many purchase situations, price can be of great importance to customers. Marketers must establish pricing strategies that are compatible with the rest of the marketing mix.

Gold is a popular precious metal where the demand is driven not only for practical use but also as a popular investments commodity. While stock market represents a country growth, thus gold price effect on stock market behavior as interest in the study. Markov Switching Vector Error Correction Models are applied to analysis the relationship between gold price and stock market changes since real financial data always exhibit regime switching, jumps or missing data through time. Besides, there are numerous specifications of Markov Switching Vector Error Correction Models and this paper will compare the intercept adjusted Markov Switching Vector Error Correction Model and intercept adjusted heteroskedasticity Markov Switching Vector Error Correction Model to determine the best model representation in capturing the transition of the time series. Results have shown that gold price has a positive relationship with Malaysia, Thailand and Indonesia stock market and a two regime intercept adjusted heteroskedasticity Markov Switching Vector Error Correction Model is able to provide the more significance and reliable result compare to intercept adjusted Markov Switching Vector Error Correction Models.

Oil prices in a new light

International Nuclear Information System (INIS)

Fesharaki, F.

1994-01-01

For a clear picture of how oil prices develop, the author steps away from the price levels to which the world is accustomed, and evaluates scientifically. What makes prices jump from one notch to another? The move results from a political or economic shock or the perception of a particular position by the futures market and the media. The shock could range from a war or an assassination to a promise of cooperation among OPEC members (when believed by the market) or to speculation about another failure at an OPEC meeting. In the oil market, only a couple of factual figures can provide a floor to the price of oil. The cost of production of oil in the Gulf is around $2 to $3/bbl, and the cost of production of oil (capital and operating costs) in key non-OPEC areas is well under $10/bbl. With some adjustments for transport and quality, a price range of $13/bbl to $16/bbl would correspond to a reasonable sustainable floor price. The reason for prices above the floor price has been a continuous fear of oil supply interruptions. That fear kept prices above the floor price for many years. The fear factor has now almost fully disappeared. The market has gone through the drama of the Iranian Revolution, the Iran-Iraq war, the tanker war, the invasion of Kuwait, and the expulsions of the Iraqis. And still the oil flowed -- all the time. It has become abundantly clear that fears above the oil market were unjustified. Everyone needs to export oil, and oil will flow under the worst circumstances. The demise of the fear factor means that oil prices tend toward the floor price for a prolonged period

The Impact of the Malaysian Minimum Cigarette Price Law: Findings from the ITC Malaysia Survey

Science.gov (United States)

Liber, Alex C.; Ross, Hana; Omar, Maizurah; Chaloupka, Frank J.

2015-01-01

Objectives Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects. Methods The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7,520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of proportions tests and adjusted Wald tests were used to evaluate changes over time in violation rates of the inflation-adjusted MPL, the proportion of illicit cigarette purchases, and mean prices. Results After the passage of the MPL, the proportion of licit brand cigarette purchases that were below the inflation-adjusted 2011 minimum price level fell substantially (before 3.9%, after 1.8%, p=0.002), while violation of the MPL for illicit brand cigarette purchases was unchanged (before 89.8%, after 91.9%, p=0.496). At the same time, the mean real price of licit cigarettes rose (p=0.006) while the mean real price of illicit cigarettes remained unchanged (p=0.134). The proportion of illicit cigarette purchases rose as well (before 13.4%, after 16.5%, p=0.041). Discussion The MPL appears not to have meaningfully changed cigarette prices in Malaysia, as licit brand prices remained well above and illicit brand prices remained well below the minimum price level before and after MPL's implementation. The increasing proportion of illicit cigarettes on the market may have undermined any positive health effects of the Malaysian MPL. The illicit cigarette trade must be addressed before a full evaluation of the Malaysian MPL's impact on public health can take place. The authors encourage the continued use of specific excise tax increases to reliably increase the price and decrease the consumption of cigarettes in Malaysia and elsewhere. PMID:25808666

Cruise tourism: a hedonic pricing approach

Directory of Open Access Journals (Sweden)

Josep Maria Espinet-Rius

2018-03-01

Full Text Available Purpose - The purpose of this paper is to examine the effect on price of different cruise industry characteristics from the point of view of actual prices. The analysis is carried out from the supply side but taking into account the real prices paid by customers. Design/methodology/approach - This paper uses the hedonic price methodology. To develop this research, a database of more than 36,000 prices paid by cruise passengers and different characteristics of ships in 2013 was built. To obtain the results, ten models have been developed with significant adjusted R2 of between 0.85 and 0.93 making the models and results robust. Findings - The results show that the main attributes affecting prices are the number of nights of the itinerary, the departure date, the number of days before departure the booking is made, the accommodation type and some facilities, such as casinos, cinemas and swimming pools. The results also yield a ranking of ship companies based on price and quality dimensions. Finally, the authors suggest some implications for management and new research. Originality/value - This paper offers a new approach in the academic literature of the cruise industry in two respects. First, in its use of a broad database of actual prices paid by passengers – more than 36,000 observations. Second, in the application of the hedonic pricing methodology, widely used in the tourism sector (see the Methodology and Database section but until now not in the cruising segment.

Pricing emission permits in the absence of abatement

International Nuclear Information System (INIS)

Hintermann, Beat

2012-01-01

If emissions are stochastic and firms are unable to control them through abatement, the cap in a permit market may be exceeded, or not be reached. I derive a binary options pricing formula that expresses the permit price as a function of the penalty for noncompliance and the probability of an exceeded cap under the assumption of no abatement. I apply my model to the EU ETS, where the rapid introduction of the market made it difficult for firms to adjust their production technology in time for the first phase. The model fits the data well, implying that the permit price may have been driven by firms hedging against stochastic emissions.

An analysis of strategic price setting in retail gasoline markets

Science.gov (United States)

Jaureguiberry, Florencia

This dissertation studies price-setting behavior in the retail gasoline industry. The main questions addressed are: How important is a retail station's brand and proximity to competitors when retail stations set price? How do retailers adjust their pricing when they cater to consumers who are less aware of competing options or have less discretion over where they purchase gasoline? These questions are explored in two separate analyses using a unique datasets containing retail pricing behavior of stations in California and in 24 different metropolitan areas. The evidence suggests that brand and location generate local market power for gasoline stations. After controlling for market and station characteristics, the analysis finds a spread of 11 cents per gallon between the highest and the lowest priced retail gasoline brands. The analysis also indicates that when the nearest competitor is located over 2 miles away as opposed to next door, consumers will pay an additional 1 cent per gallon of gasoline. In order to quantify the significance of local market power, data for stations located near major airport rental car locations are utilized. The presumption here is that rental car users are less aware or less sensitive to fueling options near the rental car return location and are to some extent "captured consumers". Retailers located near rental car locations have incentives to adjust their pricing strategies to exploit this. The analysis of pricing near rental car locations indicates that retailers charge prices that are 4 cent per gallon higher than other stations in the same metropolitan area. This analysis is of interest to regulators who are concerned with issues of consolidation, market power, and pricing in the retail gasoline industry. This dissertation concludes with a discussion of the policy implications of the empirical analysis.

Labor demand effects of rising electricity prices: Evidence for Germany

International Nuclear Information System (INIS)

Cox, Michael; Peichl, Andreas; Pestel, Nico; Siegloch, Sebastian

2014-01-01

Germany continues to play a pioneering role in replacing conventional power plants with renewable energy sources. While this might be beneficial with respect to environmental quality, it also implies increasing electricity prices. The extent to which this is associated with negative impacts on employment depends on the interrelationship between labor and electricity as input factors in the production process. In this paper, we estimate cross-price elasticities between electricity and heterogeneous labor for the German manufacturing sector. We use administrative linked employer–employee micro-data combined with information on sector-level electricity prices and usage over the period 2003–2007. We find positive, but small conditional cross-price elasticities of labor demand with respect to electricity prices, which means that electricity as an input factor can be replaced by labor to a limited extent when the production level is held constant. In the case of adjustable output, we find negative unconditional cross-price elasticities, implying that higher electricity prices lead to output reductions and to lower labor demand, with low- and high-skilled workers being affected more than medium-skilled. Resulting adverse distributional effects and potential overall job losses may pose challenges for policy-makers in securing public support for the German energy turnaround. - Highlights: • We estimate cross-price elasticities for electricity and labor in manufacturing. • We use linked employer–employee micro-data from Germany for 2003 to 2007. • We find a weak substitutability between electricity and labor for constant output. • We find complementarity between electricity and labor for adjustable output. • Low- and high-skilled workers are more affected than medium-skilled

The Effects of Oil Price Shocks on Turkish Business Cycle: A Markov Switching Approach

Directory of Open Access Journals (Sweden)

Vasif Abiyev

2015-10-01

Full Text Available Purpose - The purpose of this study is to investigate the relationship between oil price changes and the output growth in Turkey. Design/methodology/approach - The data were taken from International Financial Statistics databases, consisting of monthly data for the period 1986:01-2014:09. Different univariate Markov - switching regime autoregressive models are specified and estimated. Among them we selected univariate MSIH(3 - AR(2 model for output and extended it to verify if the inclusion of various asymmetric oil price shocks as an exogenous variable improves the ability of the Markov switching model. Four different oil price shocks are considered. Findings - We find that among various oil price shocks, only net oil price increases have negative effects on output growth and mitigate the magnitude of some recessionary periods in Turkey. However, it doesn’t strongly explain the behavior of business cycle in Turkey. Research limitations/implications - Our results suggest that the inclusion of other fundamental financial factors in the bivariate Markov switching model of aggregate economic activity and oil price changes becomes important to explicitly detect the negative impact of oil price shocks on output in Turkey. Originality/value - Our results support the existence of a negative relationship between oil price increases and output growth mentioned in the literature and empirical studies on Turkey.

As a result of the stability of the Geneva consumer price index, the following elements do not increase: a)\tFamily Allowance, Child Allowance and Infant Allowance (Annex R A 3); b)\tReimbursement of education fees: maximum amounts of reimbursement (Annex R A 4.01) for the academic year 2007/2008. Related adjustments will be applied, wherever applicable, to Paid Associates and Students. As in the past, the actual percentage increase of each salary position may vary, due to the application of a constant step value and rounding effects. Human Resources Department Tel. 73566

Price synchronization in retailing: some empirical evidence

Directory of Open Access Journals (Sweden)

Marcelo Resende

2014-06-01

Full Text Available The paper investigates the synchronization of price changes in the context of retail tire dealers in São Paulo-Brazil and selected items in supermarkets for cleaning supplies and food in Rio de Janeiro-Brazil. Results indicate similar and non-negligible synchronization for different brands, although magnitudes are distant from a perfect synchronization pattern. We find interesting patterns in inter-firm competition, with similar magnitudes across different tire types. Intra-chain synchronization is substantial, indicating that a common price adjustment policy tends to be sustained for each chain across different products.

Alcohol Prices and Mortality Due to Liver Cirrhosis

Directory of Open Access Journals (Sweden)

Jon P. Nelson

2015-06-01

Full Text Available This study estimates a reduced-form regression model for mortality rates due to alcoholic liver diseases, with alcohol prices and income as explanatory variables. Panel data cover the years 2000-2010 for 21 member countries of the European Union. In the reduced form, prices affect mortality rates indirectly through the demand for alcohol, while income has potential direct and indirect effects. Country and time fixed effects are used to control for other factors that influence alcohol consumption and mortality. Special attention is paid to outliers in the data, and final results are based on the MS-estimator for robust regressions. Regression results for alcohol prices and income are sensitive to adjustments for stationary data and down-weighting of outliers and other influential data points. Final results indicate that alcohol prices do not affect mortality rates due to chronic liver diseases. Empirical results in the study do not lend support to broad price-based approaches to alcohol policy.

This article discusses alternative methods for establishing a fairer pricing mechanism for Medicare recipients who enroll in health maintenance organizations and other competitive medical plans. The current method, based upon the adjusted average per capita cost, is inadequate because it fails to adjust premium levels for differences in health status; it establishes undesirable incentives that may lead to underservice, and it is tied to costs in the fee-for-service system. Alternative methods would incorporate health status, have Medicare share the risk with HMO's, and base payment on HMO experience. PMID:10311925

Exchange rates and individual good's price misalignment: Some preliminary evidence of long-horizon predictability

OpenAIRE

Dong, Wei; Nam, Deokwoo

2011-01-01

When prices are sticky, movements in the nominal exchange rate have a direct impact on international relative prices. A relative price misalignment would trigger an adjustment in consumption and employment, and may help to predict future movements in the exchange rate. Although purchasing-power-parity fundamentals, in general, have only weak predictability, currency misalignment may be indicated by price differentials for some goods, which could then have predictive power for subsequent re-ev...

ARCH Models Efficiency Evaluation in Prediction and Poultry Price Process Formation

2016-09-01

. This study shows that the heterogeneous variance exists in error term and indicated by LM-test. Results and Discussion: Results showed that stationary test of the poultry price has a unit root and is stationary with one lag difference, and thus the price of poultry was used in the study by one lag difference. Main results showed that ARCH is the best model for fluctuation prediction. Moreover, news has asymmetric effect on poultry price fluctuation and good news has a stronger effect on poultry price fluctuation than bad news and leverage effect doesnot existin poultry price. Moreover current fluctuation does not transmit to future. One of the main assumptions of time series models is constant variance in estimated coefficients. If this assumption has not been, the estimated coefficients for the correlation between the serial data would be biased and results in wrong interpretation. The results showed that ARCH effects existed in error terms of poultry price and so the ARCH family with student t distribution should be used. Normality test of error term and exam of heterogeneous variance needed and lack of attention to its cause false conclusion. Result showed that ARCH models have good predictive power and ARMA models are less efficient than ARCH models. It shows that non-linear predictions are better than linear prediction. According to the results that student distribution should be used as target distribution in estimated patterns. Conclusion: Huge need for poultry, require the creation of infrastructure to response to demands. Results showed that change in poultry price volatility over time, may intensifies at anytime. The asymmetric effect of good and bad news in poultry price leading to consumer's reaction. The good news had significant effects on the poultry market and created positive change in the poultry price, but the bad news did not result insignificant effects. In fact, because the poultry product in the household portfolio is essential, it should not

Forward and Spot Prices in Multi-Settlement Wholesale Electricity Markets

Science.gov (United States)

Larrieu, Jeremy

In organized wholesale electricity markets, power is sold competitively in a multi-unit multi-settlement single-price auction comprised of a forward and a spot market. This dissertation attempts to understand the structure of the forward premium in these markets, and to identify the factors that may lead forward and spot prices to converge or diverge. These markets are unique in that the forward demand is price-sensitive, while spot residual demand is perfectly inelastic and must be met in full, a crucial design feature the literature often glosses over. An important contribution of this dissertation is the explicit modeling of each market separately in order to understand how generation and load choose to act in each one, and the consequences of these actions on equilibrium prices and quantities given that firms maximize joint profits over both markets. In the first essay, I construct a two-settlement model of electricity prices in which firms that own asymmetric capacity-constrained units facing convex costs compete to meet demand from consumers, first in quantities, then in prices. I show that the forward premium depends on the costliness of spot production relative to firms' ability to exercise market power by setting quantities in the forward market. In the second essay, I test the model from the first essay with unit-level capacity and marginal cost data from the California Independent System Operator (CAISO). I show that the model closely replicates observed price formation in the CAISO. In the third essay, I estimate a time series model of the CAISO forward premium in order to measure the impact that virtual bidding has had on forward and spot price convergence in California between April 2009 and March 2014. I find virtual bidding to have caused forward and spot prices to diverge due to the large number of market participants looking to hedge against - or speculate on - the occurrence of infrequent but large spot price spikes by placing virtual demand bids.

Effect of External Economic-Field Cycle and Market Temperature on Stock-Price Hysteresis: Monte Carlo Simulation on the Ising Spin Model

Science.gov (United States)

Punya Jaroenjittichai, Atchara; Laosiritaworn, Yongyut

2017-09-01

In this work, the stock-price versus economic-field hysteresis was investigated. The Ising spin Hamiltonian was utilized as the level of ‘disagreement’ in describing investors’ behaviour. The Ising spin directions were referred to an investor’s intention to perform his action on trading his stock. The periodic economic variation was also considered via the external economic-field in the Ising model. The stochastic Monte Carlo simulation was performed on Ising spins, where the steady-state excess demand and supply as well as the stock-price were extracted via the magnetization. From the results, the economic-field parameters and market temperature were found to have significant effect on the dynamic magnetization and stock-price behaviour. Specifically, the hysteresis changes from asymmetric to symmetric loops with increasing market temperature and economic-field strength. However, the hysteresis changes from symmetric to asymmetric loops with increasing the economic-field frequency, when either temperature or economic-field strength is large enough, and returns to symmetric shape at very high frequencies. This suggests competitive effects among field and temperature factors on the hysteresis characteristic, implying multi-dimensional complicated non-trivial relationship among inputs-outputs. As is seen, the results reported (over extensive range) can be used as basis/guideline for further analysis/quantifying how economic-field and market-temperature affect the stock-price distribution on the course of economic cycle.

This article discussed the role that the federal government should play in introducing a carbon price policy in Canada whereby a carbon tax would be instituted to send a price signal to those considering future investment in carbon-intensive energy projects. It focused on bridging the gap between federal and provincial jurisdictions and assessed how various carbon pricing models can play a role in environmental federalism while allowing provinces to remain involved in policy making. Policy commitments related to emissions and cap-and-trade systems were discussed along with carbon import tariffs and domestic carbon taxes. In a market-based policy on climate change, proceeds of carbon taxes will serve to reduce greenhouse gas emissions. This article also reviewed tax incentives as well as price signal systems designed to ensure successful climate change adjustments for Canadian enterprises. 1 fig.

The model has an adjusted coefficient of determination R2 of 0.90, and was validated by comparing its predictions vs. known values of 2014.

Multinational Corporations and Stock Price Crash Risk

Directory of Open Access Journals (Sweden)

Anthony May

2016-10-01

Full Text Available A nascent literature in finance and accounting on tail risk in individual stock returns concludes that bad news hoarding by corporate managers engenders sudden, extreme crashes in a firm’s stock price when the bad news is eventually made public. This literature finds that firm-specific crash risk is higher among firms with more severe asymmetric information and agency problems. A hitherto disjointed literature spanning the fields of international business, finance, and accounting suggests that geographic dispersion in a firm’s operations, and especially dispersion across different countries, gives rise to organizational complexities and greater costs of monitoring that can exacerbate asymmetric information and agency problems. Motivated by the confluence of arguments and findings from these two strands of literature, this paper examines whether stock price crash risk is higher among multinational firms than domestic firms. Using a large sample of U.S. headquartered firms during 1987-2011, we find robust evidence that multinational firms are significantly more likely to crash than domestic firms. Moreover, we show that the difference in crash risk between multinational and domestic firms is most acute among firms with weaker corporate governance mechanisms, including weaker shareholder rights, less independent boards, and less stable institutional ownership. Our analysis indicates that stronger monitoring from each of these three governance mechanisms significantly attenuates the positive relation between crash risk and multinationality. Our findings are robust to the use of alternative measures of crash risk and to controlling for known determinants of crash risk identified in prior studies. Our study offers new insights that should hold value for scholars and market participants interested in understanding the implications of heighted agency problems that multinational firms are likely to encounter and scholars and market participants

Historically, none of these methods has performed very well, but a well-thought-out model is still useful as a basis from which to adjust to new circumstances and try again

Revisiting short-term price and volatility dynamics in day-ahead electricity markets with rising wind power

International Nuclear Information System (INIS)

Li, Yuanjing

2015-01-01

This paper revisits the short-term price and volatility dynamics in day-ahead electricity markets in consideration of an increasing share of wind power, using an example of the Nord Pool day-ahead market and the Danish wind generation. To do so, a GARCH process is applied, and market coupling and the counterbalance effect of hydropower in the Scandinavian countries are additionally accounted for. As results, we found that wind generation weakly dampens spot prices with an elasticity of 0.008 and also reduces price volatility with an elasticity of 0.02 in the Nordic day-ahead market. The results shed lights on the importance of market coupling and interactions between wind power and hydropower in the Nordic system through cross-border exchanges, which play an essential role in price stabilization. Additionally, an EGARCH specification confirms an asymmetric influence of the price innovations, whereby negative shocks produce larger volatility in the Nordic spot market. While considering heavy tails in error distributions can improve model fits significantly, the EGARCH model outperforms the GARCH model on forecast evaluations. (author)

Chevallier, Julien

2010-01-01

This article investigates the impact of news concerning the development of emissions trading in Australia (such as the Carbon Pollution Reduction Scheme (CPRS)) on wholesale electricity spot prices, by using a database of 117 news announcements from December 1, 1998 to July 1, 2009. As power producers constitute the bulk of the participants of the proposed Australian emissions trading scheme, regulatory changes (about allocation, banking, coverage, targets) are indeed likely to affect the five interconnected electricity markets in New South Wales, Queensland, South Australia, Victoria, and Tasmania. We assess these effects with an ARMA(1,1)-GARCH(1,1) model, where daily electricity spot prices are regressed against exogenous variables in the mean and variance equations. This article constitutes the first empirical analysis of Australian ETS news effects on electricity wholesale spot prices. Our results show two asymmetric types of news effects, depending on their information content. (author)

2015-08-01

In Thailand, total drug expenditure has grown rapidly. Recently, the Thai government has addressed the issue of drug pricing, but the prices of single-source drugs remain a major challenge. To examine equitable prices of single-source drugs in Thailand. A total of 98 single-source and high-expenditure drugs were examined. Unit prices from the Drug and Medical Supplies Information Center (DMSIC) and National Average Drug Acquisition Cost (NADAC) were used to represent drug prices at the provider level in Thailand and the U.S., respectively. Data for measuring drug affordability, e.g., dose and poverty line, were obtained from Micromedex online and the National Statistical Office (NSO). The U.S. drug prices were adjusted by the Human Development Index (HDI) to be equitable prices for Thailand. Purchasing Power Parity (PPP) was used to convert US currency into Thai baht. All prices in this study were based on the year 2012. Catastrophic, Impoverishment, and WHO/Health Action International (HAI) approaches were used to determine Thai citizens' ability to afford the study drugs. Finally, uncertainty analyses were conducted. From all study drugs, 55 single-source drugs were priced higher than their equitable prices, ranging from 0.38 to 422.36% higher. Among these, 28 items were antineoplastic drugs. The prices of drugs outside the National List of Essential Medicines (NLEM), as well as the country's newer drugs, tended to be higher than their calculated equitable prices. The majority of drugs in Thailand priced higher than equitable prices were unaffordable for most Thai citizens. The uncertainty analyses revealed that almost all results were relatively robust. Most single-source drug prices in Thailand were higher than their equitable prices, and were likely to be unaffordable to Thai citizens.

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

Energy Technology Data Exchange (ETDEWEB)

Zandi, F R

1982-01-01

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

The impact of the Malaysian minimum cigarette price law: findings from the ITC Malaysia Survey.

Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects. The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of proportions tests and adjusted Wald tests were used to evaluate changes over time in violation rates of the inflation-adjusted MPL, the proportion of illicit cigarette purchases and mean prices. After the passage of the MPL, the proportion of licit brand cigarette purchases that were below the inflation-adjusted 2011 minimum price level fell substantially (before 3.9%, after 1.8%, p=0.002), while violation of the MPL for illicit brand cigarette purchases was unchanged (before 89.8%, after 91.9%, p=0.496). At the same time, the mean real price of licit cigarettes rose (p=0.006), while the mean real price of illicit cigarettes remained unchanged (p=0.134). The proportion of illicit cigarette purchases rose as well (before 13.4%, after 16.5%, p=0.041). The MPL appears not to have meaningfully changed cigarette prices in Malaysia, as licit brand prices remained well above and illicit brand prices remained well below the minimum price level before and after MPL's implementation. The increasing proportion of illicit cigarettes on the market may have undermined any positive health effects of the Malaysian MPL. The illicit cigarette trade must be addressed before a full evaluation of the Malaysian MPL's impact on public health can take place. The authors encourage the continued use of specific excise tax increases to reliably increase the price and decrease the consumption of cigarettes in Malaysia and elsewhere.

2006-01-01

This paper presents evidence of the effects of OPEC policy decisions on the US and UK stock markets, as well as on oil prices, during periods of conflict and non-conflict from 1986 to 2004. The outcomes of this study are potentially valuable in assessing future strategies for OPEC policy decisions on oil production targets for its Members. This paper also adds to the strong body of evidence supporting the hypothesis that market returns are influenced by factors that affect business conditions, such as oil price shocks. The key findings are that there are asymmetric reactions to OPEC policy decisions during conflict periods for the US and UK stock markets. During conflict periods, oil markets require time to incorporate OPEC decisions. Conversely, in non-conflict periods the evidence suggests that the oil markets incorporate OPEC decisions efficiently.

2003-01-01

This paper re-examines the issue of asymmetries in the transmission of shocks to crude oil prices onto the retail price of gasoline. The distinguishing features are: (i) use of updated and comparable data to carry out an international comparison of gasoline markets; (ii) two-stage modeling of the transmission mechanism, in order to assess possible asymmetries at either the refinery stage, the distribution stage or both; (iii) use of asymmetric error correction models to distinguish between short-run and long-run asymmetries; (iv) explicit, possibly asymmetric, role of the exchange rate; (v) bootstrapping of F-tests of asymmetries, in order to overcome the low-power problem of conventional testing procedures. In contrast to several previous findings, the results generally point to widespread differences in both adjustment speeds and short-run responses when input prices rise or fall. (Author)

Product differentiation, competition and prices in the retail gasoline industry

Science.gov (United States)

Manuszak, Mark David

This thesis presents a series of studies of the retail gasoline industry using data from Hawaii. This first chapter examines a number of pricing patterns in the data and finds evidence that gasoline stations set prices which are consistent with a number of forms of price discrimination. The second chapter analyzes various patterns of cross-sectional, cross-market and intertemporal variation in the data to investigate their suitability for use in structural econometric estimation. The remainder of the dissertation consists of specification and estimation of a structural model of supply and demand for retail gasoline products sold at individual gasoline stations. This detailed micro-level analysis permits examination of a number of important issues in the industry, most notably the importance of spatial differentiation in the industry. The third chapter estimates the model and computes new equilibria under a number of asymmetric taxation regimes in order to examine the impact of such tax policies on producer and consumer welfare as well as tax revenue. The fourth chapter examines whether there is any evidence of tacitly collusive behavior in the Hawaiian retail gasoline industry and concludes that, in fact, conduct is fairly competitive in this industry and market.

Raising the price of cigarettes by increasing taxation has been associated with improved perinatal and child health outcomes. Transnational tobacco companies have sought to undermine tobacco tax policy by adopting pricing strategies that maintain the availability of budget cigarettes. To assess associations between median cigarette prices, cigarette price differentials, and infant mortality across the European Union. A longitudinal, ecological study was conducted from January 1, 2004, to December 31, 2014, of infant populations in 23 countries (comprising 276 subnational regions) within the European Union. Median cigarette prices and the differential between these and minimum cigarette prices were obtained from Euromonitor International. Pricing differentials were calculated as the proportions (%) obtained by dividing the difference between median and minimum cigarette price by median price. Prices were adjusted for inflation. Annual infant mortality rates. Associations were assessed using linear fixed-effect panel regression models adjusted for smoke-free policies, gross domestic product, unemployment rate, education, maternal age, and underlining temporal trends. Among the 53 704 641 live births during the study period, an increase of €1 (US $1.18) per pack in the median cigarette price was associated with a decline of 0.23 deaths per 1000 live births in the same year (95% CI, -0.37 to -0.09) and a decline of 0.16 deaths per 1000 live births the following year (95% CI, -0.30 to -0.03). An increase of 10% in the price differential between median-priced and minimum-priced cigarettes was associated with an increase of 0.07 deaths per 1000 live births (95% CI, 0.01-0.13) the following year. Cigarette price increases across 23 European countries between 2004 and 2014 were associated with 9208 (95% CI, 8601-9814) fewer infant deaths; 3195 (95% CI, 3017-3372) infant deaths could have been avoided had there been no cost differential between the median-priced and

Convergence of decision rules for value-based pricing of new innovative drugs.

Science.gov (United States)

Gandjour, Afschin

2015-04-01

Given the high costs of innovative new drugs, most European countries have introduced policies for price control, in particular value-based pricing (VBP) and international reference pricing. The purpose of this study is to describe how profit-maximizing manufacturers would optimally adjust their launch sequence to these policies and how VBP countries may best respond. To decide about the launching sequence, a manufacturer must consider a tradeoff between price and sales volume in any given country as well as the effect of price in a VBP country on the price in international reference pricing countries. Based on the manufacturer's rationale, it is best for VBP countries in Europe to implicitly collude in the long term and set cost-effectiveness thresholds at the level of the lowest acceptable VBP country. This way, international reference pricing countries would also converge towards the lowest acceptable threshold in Europe.

The oil price; Le prix du petrole

Energy Technology Data Exchange (ETDEWEB)

Alba, P. [Institut Francais du Petrole (IFP), 92 - Rueil-Malmaison (France)

2000-05-01

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.

The Effects Of Asymmetric Transmission Of Exchange Rate On Inflation In Iran: Application Of Threshold Models

Directory of Open Access Journals (Sweden)

Naghdi Yazdan

2015-08-01

Full Text Available Given the recent fluctuation in the exchange rate and the presence of several factors such as the various economy-political sanctions (mainly embargos on oil and banking, extreme volatility in different economic fields, and consequently the devaluation of national and public procurement -A landmark that is emanating from exchange rate fluctuation - two points should be noted: First, it is essential to review the effect of exchange rate fluctuation on macro economic variables such as inflation and to provide appropriate policies. Second, the existence of this condition provides the chance to study the relation between exchange rate and inflation in a non-linear and asymmetric method. Hence, the present study seeks to use TAR model and, on the basis of monthly time series data over the period March 2002 to March 2014, to analyze the cross-asymmetric and non-linear exchange rate on consumer price index (CPI in Iran. The results also show the presence of an asymmetric long-term relationship between these variables (exchange rate and CPI. Also, in the Iranian economy, the effect of negative shocks of exchange rate on inflation is more sustainable than the one from positive shocks.

Oil price assumptions in macroeconomic forecasts: should we follow future market expectations?

International Nuclear Information System (INIS)

Coimbra, C.; Esteves, P.S.

2004-01-01

In macroeconomic forecasting, in spite of its important role in price and activity developments, oil prices are usually taken as an exogenous variable, for which assumptions have to be made. This paper evaluates the forecasting performance of futures market prices against the other popular technical procedure, the carry-over assumption. The results suggest that there is almost no difference between opting for futures market prices or using the carry-over assumption for short-term forecasting horizons (up to 12 months), while, for longer-term horizons, they favour the use of futures market prices. However, as futures market prices reflect market expectations for world economic activity, futures oil prices should be adjusted whenever market expectations for world economic growth are different to the values underlying the macroeconomic scenarios, in order to fully ensure the internal consistency of those scenarios.

Oil price, government policies fuel industry's shift from U.S

International Nuclear Information System (INIS)

Silas, C.J.

1991-01-01

The world exploration outlook starts with the outlook for the price of oil. This paper reports that oil prices and government policies for fuel industries shift from the U.S. If we've learned anything in the past decade it's that we're not very good at predicting oil prices. We can build economic models of supply and demand but we can't build models for political events in the Middle East or the actions of someone like Saddam Hussein. As we look to 2000 our best estimate is that oil will remain at about $20 for the near term and move upward very gradually during the rest of the decade. Of course, rising demand eventually should cause oil prices to break out and show some strength. But not soon. We don't see oil prices overcoming inflation until the latter part of the decade. And we aren't expecting oil prices much above $25 in inflation adjusted terms until the next century

Differential pricing of new pharmaceuticals in lower income European countries.

Kaló, Zoltán; Annemans, Lieven; Garrison, Louis P

2013-12-01

Pharmaceutical companies adjust the pricing strategy of innovative medicines to the imperatives of their major markets. The ability of payers to influence the ex-factory price of new drugs depends on country population size and income per capita, among other factors. Differential pricing based on Ramsey principles is a 'second-best' solution to correct the imperfections of the global market for innovative pharmaceuticals, and it is also consistent with standard norms of equity. This analysis summarizes the boundaries of differential pharmaceutical pricing for policymakers, payers and other stakeholders in lower-income countries, with special focus on Central-Eastern Europe, and describes the feasibility and implications of potential solutions to ensure lower pharmaceutical prices as compared to higher-income countries. European stakeholders, especially in Central-Eastern Europe and at the EU level, should understand the implications of increased transparency of pricing and should develop solutions to prevent the limited accessibility of new medicines in lower-income countries.

Energy Prices and Internal Costs in Croatian Energy System Restructuring

International Nuclear Information System (INIS)

Potocnik, V. , Magdic, M.

1995-01-01

After social and political changes in 1990, energy prices in Croatia have been getting closer to the West European averages, faster than in the most European countries in transition. The energy prices for industry are almost at the West European level, while the energy prices of electricity and natural gas for households and those of the gasoline are well behind. If the population purchasing power parity (PPP) is taken into account, these relations change. While the internalization of external energy costs is under way in the developed world, it has not practically started yet in Croatia. The Croatian energy system restructuring shall require gradual adjustment of energy prices, together with multistage internalization of external energy costs. (author). 6 refs., 3 tabs., 2 figs

Role of oil price shocks on macroeconomic activities: An SVAR approach to the Malaysian economy and monetary responses

International Nuclear Information System (INIS)

Ali Ahmed, Huson Joher; Wadud, I.K.M. Mokhtarul

2011-01-01

This study examines the impact of oil price uncertainty on Malaysian macroeconomic activities and monetary responses. We use a structural VAR (SVAR) model based on monthly data over the period 1986−2009. The EGARCH model estimates show an important asymmetric effect of oil price shocks on the conditional oil price volatility. Dynamic impulse response functions obtained from the SVAR model show a prolonged dampening effect of oil price volatility shock on Malaysian industrial production. We also find that levels of Consumer Price Index (CPI) decline with a positive shock to oil price uncertainty. This is the result of negative demand shock due to the postponement of consumption of big ticket items by individuals, households and other sectors of the economy. We also found that the Malaysian central bank adopts an expansionary monetary policy in response to oil price uncertainty. Variance decomposition analysis reconfirms that volatility in the oil price is the second most important factor to explain the variance of industrial production after its own shocks. These results shed some light on how the central bank of Malaysia can use controlling mechanisms to stabilize aggregate output and price level. - Highlights: ► Conditional volatility of the oil price causes a significant decline in aggregate output. ► Price level falls significantly to one standard deviation shock to oil price uncertainty. ► Malaysian central bank adopts an expansionary monetary policy in response to oil price shocks.

Jump Testing and the Speed of Market Adjustment

Asymmetric peer effects in the analysis of cigarette smoking among young people in the United States, 1992-1999.

Science.gov (United States)

Harris, Jeffrey E; González López-Valcárcel, Beatriz

2008-03-01

We extend the recent literature on peer effects to test the possible role of asymmetric social influences in the determination of youth smoking. We analyzed cigarette smoking among people aged 15-24 in approximately 90,000 households in the 1992-1999 U.S. Current Population Surveys. The presence of additional smoking sibling in a household, we estimated, raised a young person's probability of smoking by 7.6%, while each non-smoking sibling lowered the probability by an estimated 3.5%. Moreover, the overall deterrent effect of an increase in cigarette price on the probability of smoking was approximately 60% greater than the estimated effect when peer influences were held constant. The concept of asymmetric social influence may have applications in other fields, including labor economics, education, crime prevention, and group dynamics.

Water Authorities’ Pricing Strategies to Recover Supply Costs in the Absence of Water Metering for Irrigated Agriculture

Directory of Open Access Journals (Sweden)

Alban Lika

2017-11-01

Full Text Available Most of the irrigated agricultural regions in Europe are supplied by surface irrigation networks managed by local water authorities (WAs. Under such conditions, WAs are not able to fully monitor water usage and farmers have an information advantage vis-a-vis the WA. This results in the water authority suffering ‘pricing failure’ if it decides to apply an incentive pricing strategy (tariffs proportional to the alleged water uses. Indeed, farmers could exploit their information advantage by behaving in an opportunistic manner, withdrawing more water than declared, and ultimately paying less than they should. This situation could also undermine the efficacy and the efficiency of the WA incentive pricing strategies. This paper analyses incentive water pricing schemes under asymmetric information by the means of a Principal-Agent model. The Agency problem between the WA and farmers is addressed by introducing a monitoring strategy that would enable the WA to detect farms action. In doing so, we compare incentive strategies with flat rate water pricing and investigate under what conditions the WA might provide/not provide incentive water pricing in the absence of water metering.

Pricing of surgeries for colon cancer: patient severity and market factors.

Science.gov (United States)

Dor, Avi; Koroukian, Siran; Xu, Fang; Stulberg, Jonah; Delaney, Conor; Cooper, Gregory

2012-12-01

This study examined effects of health maintenance organization (HMO) penetration, hospital competition, and patient severity on the uptake of laparoscopic colectomy and its price relative to open surgery for colon cancer. The MarketScan Database (data from 2002-2007) was used to identify admissions for privately insured colorectal cancer patients undergoing laparoscopic or open partial colectomy (n = 1035 and n = 6389, respectively). Patient and health plan characteristics were retrieved from these data; HMO market penetration rates and an index of hospital market concentration, the Herfindahl-Hirschman index (HHI), were derived from national databases. Logistic and logarithmic regressions were used to examine the odds of having laparoscopic colectomy, effect of covariates on colectomy prices, and the differential price of laparoscopy. Adoption of laparoscopy was highly sensitive to market forces, with a 10% increase in HMO penetration leading to a 10.9% increase in the likelihood of undergoing laparoscopic colectomy (adjusted odds ratio = 1.109; 95% confidence interval [CI] = 1.062, 1.158) and a 10% increase in HHI resulting in 6.6% lower likelihood (adjusted odds ratio = 0.936; 95% CI = 0.880, 0.996). Price models indicated that the price of laparoscopy was 7.6% lower than that of open surgery (transformed coefficient = 0.927; 95% CI = 0.895, 0.960). A 10% increase in HMO penetration was associated with 1.6% lower price (transformed coefficient = 0.985; 95% CI = 0.977, 0.992), whereas a 10% increase in HHI was associated with 1.6% higher price (transformed coefficient = 1.016; 95% CI = 1.006, 1.027; P prices. Moreover, laparoscopic surgery may result in cost savings, while market pressures contribute to its adoption. Copyright © 2012 American Cancer Society.

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

Asymmetric cation-binding catalysis

DEFF Research Database (Denmark)

Oliveira, Maria Teresa; Lee, Jiwoong

2017-01-01

The employment of metal salts is quite limited in asymmetric catalysis, although it would provide an additional arsenal of safe and inexpensive reagents to create molecular functions with high optical purity. Cation chelation by polyethers increases the salts' solubility in conventional organic...... solvents, thus increasing their applicability in synthesis. The expansion of this concept to chiral polyethers led to the emergence of asymmetric cation-binding catalysis, where chiral counter anions are generated from metal salts, particularly using BINOL-based polyethers. Alkali metal salts, namely KF...... highly enantioselective silylation reactions in polyether-generated chiral environments, and leading to a record-high turnover in asymmetric organocatalysis. This can lead to further applications by the asymmetric use of other inorganic salts in various organic transformations....

The price level and monetary policy

Directory of Open Access Journals (Sweden)

Charles P. Kindleberger

2002-03-01

Full Text Available Most central banks are required to or choose to stabilize a price index, largely by manipulating short term interest rates. A serious problem is which index to choose among the national income deflator, wholesale prices, the cost of living, with or eliminating highly volatile commodities such as food and energy, to produce a core index, plus others such as housing, including or without imputed rent of owner-occupied houses, or assets, whether equities or houses. No obvious and widely agreed index exists. Even if there were a clear choice, there remains a question whether a central bank should carefully consider action in order to achieve other goals: full employment, adjustment of the balance of payments, of the exchange rate, prevention of bubbles in asset prices, or recovery from financial crises. If so, the question of central bank weapons remains: monetary expansion or contraction, credit controls, for overall or for particular purposes, and moral suasion.

Chaos in oil prices? Evidence from futures markets

International Nuclear Information System (INIS)

Adrangi, B.; Chatrath, A.; Dhanda, K.K.; Raffiee, K.

2001-01-01

We test for the presence of low-dimensional chaotic structure in crude oil, heating oil, and unleaded gasoline futures prices from the early 1980s. Evidence on chaos will have important implications for regulators and short-term trading strategies. While we find strong evidence of non-linear dependencies, the evidence is not consistent with chaos. Our test results indicate that ARCH-type processes, with controls for seasonal variation in prices, generally explain the non-linearities in the data. We also demonstrate that employing seasonally adjusted price series contributes to obtaining robust results via the existing tests for chaotic structure. Maximum likelihood methodologies, that are robust to the non-linear dynamics, lend support for Samuelson's hypothesis on contract-maturity effects in futures price-changes. However, the tests for chaos are not found to be sensitive to the maturity effects in the futures contracts. The results are robust to controls for the oil shocks of 1986 and 1991

Quantifying Correlation Uncertainty Risk in Credit Derivatives Pricing

Directory of Open Access Journals (Sweden)

Colin Turfus

2018-04-01

Full Text Available We propose a simple but practical methodology for the quantification of correlation risk in the context of credit derivatives pricing and credit valuation adjustment (CVA, where the correlation between rates and credit is often uncertain or unmodelled. We take the rates model to be Hull–White (normal and the credit model to be Black–Karasinski (lognormal. We summarise recent work furnishing highly accurate analytic pricing formulae for credit default swaps (CDS including with defaultable Libor flows, extending this to the situation where they are capped and/or floored. We also consider the pricing of contingent CDS with an interest rate swap underlying. We derive therefrom explicit expressions showing how the dependence of model prices on the uncertain parameter(s can be captured in analytic formulae that are readily amenable to computation without recourse to Monte Carlo or lattice-based computation. In so doing, we crucially take into account the impact on model calibration of the uncertain (or unmodelled parameters.

LABOUR MOBILITY AS AN ADJUSTMENT MECHANISM IN THE EURO AREA

Directory of Open Access Journals (Sweden)

Cristina Puiu

2011-12-01

Full Text Available The aim of this paper is to assess the capacity of labour mobility in the euro area to act as an adjustment mechanism in the event of an asymmetric shock. According to the optimum currency area theory, labour mobility has been emphasized as one of the main adjustment mechanism. Given the present situation, where there are major concerns about the future of the euro area, it is necessary to study if the mechanism for stability works and if it can be improved. Considering the difficulty of quantifying the labour mobility, we have analyzed the net migration and the regulations regarding labour market. The empirical evidence shows that labour mobility does not act as a sufficient adjustment mechanism.

The Analysis of the Potential Environmental Benefits by Investigating the Hedonistic Price

Directory of Open Access Journals (Sweden)

Giani Gradinaru

2008-07-01

Full Text Available Consumers get some usefulness from the attributes of heterogeneous products and they adjust their acquisitions as a response to the existing differences. Producers or vendors confront with varying prices depending on the scale of attributes provided. A plan for balancing the prices is developed as a consequence of the market interaction between the consumers and suppliers (by analogy it happens in the case of the interaction between employees and employers on the labour market. Taking into consideration the late concepts regarding hedonistic price, the article presents a way of analysis of potential benefits that environment may offer to human communities by hedonistic price investigation, using regression as instrument.

Oil price shocks and economy: an open question

International Nuclear Information System (INIS)

Di Marzio, G.

2006-01-01

During the 1970s and 1980s advanced oil importing economies faced the adverse effects of oil supply disruptions with abrupt energy price rise, followed by sensible business cycle inversions and stagflation. The negative effects of the sharp energy price increase were amplified by factors such the induced costly resources reallocation between labour and capital, and between sectors of activity; rising uncertainty discouraging investments, and income redistribution consequences on aggregate demands After a shock the economic system generally adjusts in favour of less energy intensive industries; this leads pauses in production as part of the existing capital stock become obsolete, and causes resources under utilization. Since the 1970s a number of economists have been sceptical about why even large price shocks in a resource that accounts for less than 3-4 pct. of global GDP could cause losses of magnitude as those experienced in most advanced economies. They believe that monetary policy has played a role in generating the observed negative correlation between oil prices and economic activity, and question whether the post-oil-shock recessions were attributable to the oil price shocks themselves or to the monetary policy responding to these shocks. Empirical research largely shows a primary responsibility of large price shocks and major oil-supply disruptions on recessionary movements of GDP. Energy prices have risen sharply since 2003, driven by strengthening global demand; market fundamentals suggest that a considerable fraction of recent hikes will be permanent and current price levels remain credible. With limited spare capacity, the medium term oil supply-demand balance is expected to remain tight, and the price probably near current levels. Today' s high oil prices reflect the effects of sustained energy demand trends and, jointly, oil industry under investment during and after the low price era of the 1990s. The apparent moderate macro economic effects of the

Charge Asymmetric Cosmic Rays as a probe of Flavor Violating Asymmetric Dark Matter

DEFF Research Database (Denmark)

Masina, Isabella; Sannino, Francesco

2011-01-01

The recently introduced cosmic sum rules combine the data from PAMELA and Fermi-LAT cosmic ray experiments in a way that permits to neatly investigate whether the experimentally observed lepton excesses violate charge symmetry. One can in a simple way determine universal properties of the unknown...... component of the cosmic rays. Here we attribute a potential charge asymmetry to the dark sector. In particular we provide models of asymmetric dark matter able to produce charge asymmetric cosmic rays. We consider spin zero, spin one and spin one-half decaying dark matter candidates. We show that lepton...... flavor violation and asymmetric dark matter are both required to have a charge asymmetry in the cosmic ray lepton excesses. Therefore, an experimental evidence of charge asymmetry in the cosmic ray lepton excesses implies that dark matter is asymmetric....

Prices, Costs, and Affordability of New Medicines for Hepatitis C in 30 Countries: An Economic Analysis.

2016-05-01

New hepatitis C virus (HCV) medicines have markedly improved treatment efficacy and regimen tolerability. However, their high prices have limited access, prompting wide debate about fair and affordable prices. This study systematically compared the price and affordability of sofosbuvir and ledipasvir/sofosbuvir across 30 countries to assess affordability to health systems and patients. Published 2015 ex-factory prices for a 12-wk course of treatment were provided by the Pharma Price Information (PPI) service of the Austrian public health institute Gesundheit Österreich GmbH or were obtained from national government or drug reimbursement authorities and recent press releases, where necessary. Prices in Organisation for Economic Co-operation and Development (OECD) member countries and select low- and middle-income countries were converted to US dollars using period average exchange rates and were adjusted for purchasing power parity (PPP). We analysed prices compared to national economic performance and estimated market size and the cost of these drugs in terms of countries' annual total pharmaceutical expenditure (TPE) and in terms of the duration of time an individual would need to work to pay for treatment out of pocket.

Introduction New hepatitis C virus (HCV) medicines have markedly improved treatment efficacy and regimen tolerability. However, their high prices have limited access, prompting wide debate about fair and affordable prices. This study systematically compared the price and affordability of sofosbuvir and ledipasvir/sofosbuvir across 30 countries to assess affordability to health systems and patients. Methods and Findings Published 2015 ex-factory prices for a 12-wk course of treatment were provided by the Pharma Price Information (PPI) service of the Austrian public health institute Gesundheit Österreich GmbH or were obtained from national government or drug reimbursement authorities and recent press releases, where necessary. Prices in Organisation for Economic Co-operation and Development (OECD) member countries and select low- and middle-income countries were converted to US dollars using period average exchange rates and were adjusted for purchasing power parity (PPP). We analysed prices compared to national economic performance and estimated market size and the cost of these drugs in terms of countries’ annual total pharmaceutical expenditure (TPE) and in terms of the duration of time an individual would need to work to pay for treatment out of pocket.

Beta measured from the capital asset pricing model (CAPM) is the most widely used risk to estimate expected return. In this paper factors that influence Shanghai A-share stock return based on CAPM are explored and investigated. Price data of 312 companies listed on Shanghai Stock Exchange (SSE) from the year 2000 to 2011 are investigated. This study employed the Fama-MacBeth cross-sectional method to avoid weakness of traditional CAPM. In addition, this study improves the model by adjusting missing data. Findings of this study justifies that systematic risk can explain the portfolios' returns of China SSE stock market.

Relative Price Levels and Current Accounts: An Exploration

Full Text Available This paper studies the links between current accounts and relative price levels, finding that current account changes are associated with sizable future relative price levels effects. This is done in panel regressions of the Penn effect, adding a lagged current account/GDP and other explanatory variables. Higher GDP/ capita and a greater export share of manufacturing tend to mitigate the real exchange rate impact of lagged current accounts. Active management of current accounts may provide a powerful adjustment channel, mitigating the real exchange rate effects of volatile terms of trade, and may explain the growing proliferation of Sovereign Wealth Funds.

Gas prices and price process

International Nuclear Information System (INIS)

Groenewegen, G.G.

1992-01-01

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