efficiency and information aggregation in auctions the tension between allocative efficiency and information aggregation is explored in the context of an auction k identical objects of unknown quality are auctioned off to n bidders whose tastes affect their valuation of an object of given quality bidders receive a signal about the quality of the objects the k highest bidders get an object and pay a price equal to the k first highest bid we find conditions under which in the limit objects are allocated efficiently to those with the highest tastes and price converges in probability to the value of an object to the marginal taste type

prices and the winner s curse we usually assume that increases in supply allocation by rationing and exclusion of potential buyers reduce prices but all these activities raise the expected price in an important set of cases when common value assets are sold furthermore when we make the assumptions needed to rule out these anomalies for symmetric buyers small asymmetries among the buyers necessarily cause the anomalies to reappear our results help explain rationing in initial public offerings and outcomes of spectrum auctions we illustrate our results in the wallet game and in another new game we introduce the maximum game

petrol prices oil price rises and oil price falls some evidence for the uk since 1972 this paper examines the relationship between retail petrol prices excise duties and crude oil prices in the uk over the period 1973 1988 the existence of a stable relationship between the petrol price level of excise duty and spot oil price is confirmed through use of the cointegration approach although the speed of reaction of petrol prices to changes in the crude price depends on whether crude prices are rising or falling any asymmetry in the pricing response is virtually absent after an adjustment period of only four months

optimal selling strategies when buyers may have hard information abstract consider a revenue maximizing seller who can sell an object to one of n potential buyers each buyer either has hard information about his valuation i e evidence that cannot be forged or is ignorant the optimal mechanism is characterized it turns out that more ignorance can increase the expected total surplus even when the buyers are ex ante symmetric the object may be sold to a buyer who does not have the largest willingness to pay nevertheless an additional buyer increases the expected total surplus in the symmetric case whereas more competition can be harmful if there are ex ante asymmetries

the role of transaction costs for financial volatility evidence from the paris bourse this paper analyzes the causal linkage between transaction costs and financial volatility under two methodological improvements over the existing literature first we use panel data in which exogenous transaction cost differences in the french stock market are induced by price level dependent minimum price variation rules tick size rules unlike in previous studies based on one time regulatory tick size changes like the u s decimalization we can separately identify and control for marketwide volatility changes second we avoid the pitfalls of biased volatility measurement across regimes by using the range as a tick size robust volatility metric panel regressions controlling for marketwide volatility effects show at high levels of statistical significance that the hourly range volatility of individual stocks increases by more than 30 for a 20 exogenous increase in transaction costs due to tick size variations in the french trading system in the light of this evidence higher transaction costs in general and security transaction taxes in particular should be considered as volatility increasing jel f3 g1 g14

market structure and price adjustment in the u s wholesale gasoline markets abstract the issue of sticky prices in u s wholesale gasoline market is re examined allowing for the effect of market structure due to increased market concentration caused by mergers acquisitions and joint ventures which started in the late 1990s in the u s oil industry i investigate the effects of market structure on the pattern of price adjustment based on the notion that increased market concentration leads to downward price stickiness and asymmetric short run price adjustment in the transmission of crude price changes to wholesale gasoline price i find that market concentration has an insignificant asymmetric effect on the speed of price adjustment but a significant asymmetric effect on short run price adjustments in the response of wholesale gasoline prices to crude price shocks in three u s wholesale markets furthermore the signs on the coefficients of market concentration effects on price dynamics in the models support the assertion that increased market concentration leads to downward price stickiness in only one of the three markets examined overall the results indicate that market structure does not have a strong effect on the dynamics of price adjustment

testing for asymmetric pricing in the canadian retail gasoline market abstract this paper applies a threshold regression model to test for asymmetric pricing in the retail gasoline market in canada using weekly data for the period january 1990 to december 1996 we present results for 13 canadian cities for both premium and regular gasoline within the context of an error correction model we test for the presence of asymmetric price behaviour using average changes in crude prices as well as various lags for the change in crude as possible thresholds we are unable to find any evidence to support this view

trading volume and asset liquidity since the depth and liquidity of a market depend on the entry decisions of all potential participants each trader assesses them according to conjectures about entry by others if trade is equally costly across markets this externality leads to the concentration of trade on one market if not it can produce multiple conjectural equilibria some where trade concentrates on one market and others where large traders resort to a separate market or to search for a trading partner while fragmentation is welfare reducing in the two market case no such ranking is possible if it involves off exchange search

asymmetric error correction models for the oil gasoline price relationship abstract the existing literature on price asymmetries does not systematically investigate the sensitivity of the empirical results to the choice of a particular econometric specification this paper fills this gap by providing a detailed comparison of the three most popular models designed to describe asymmetric price behavior namely asymmetric ecm autoregressive threshold ecm and ecm with threshold cointegration each model is estimated on a common monthly data set for the gasoline markets of france germany italy spain and uk over the period 1985 2003 all models are able to capture the temporal delay in the reaction of retail prices to changes in spot gasoline and crude oil prices as well as some evidence of asymmetric behavior however the type of market and the number of countries which are characterized by asymmetric oil gasoline price relations vary across models the asymmetric ecm prescribes that long run price asymmetries are most likely to be found in the second stage of the transmission chain conversely the ecm with threshold cointegration suggests that long run price asymmetries vary across countries and markets short run price asymmetries are captured by the asymmetric ecm specification and the tar ecm the latter model suggests that all european countries are likely to be affected by asymmetries at the distribution stage while the results obtained with the asymmetric ecm are mixed

rockets and feathers the asymmetric speed of adjustment of uk retail gasoline prices to cost changes abstract the paper develops a quadratic quantity adjustment model to test the hypothesis put forward in the recent monopolies and mergers commission report that the speed of adjustment of uk retail gasoline prices to cost changes is more rapid when costs rise than when they fall and that the adjustment path is more concentrated around the mean value on the upswing using data from 1982 to 1989 evidence of faster and more concentrated responses to cost increases were found

path dependency and input substitution implications for energy policy modelling in most policy oriented energy models the effectiveness of energy policy instruments crucially depends both on the values of the substitution elasticities between the various inputs and on the rates of technological progress in this paper we argue that due to the fixed cost nature of adjustments to relative price changes these technological parameters are affected by past developments failing to account for the role of history will result in biased parameter estimates and hence the implication for energy policy modelling is that the estimation period should be carefully selected we provide an empirical illustration using data for the netherlands

momentum investment strategies portfolio performance and herding a study of mutual fund behavior this study analyzes the extent to which mutual funds purchase stocks based on their past returns as well as their tendency to exhibit herding behavior i e buying and selling the same stocks at the same time the authors find that 77 percent of the mutual funds were momentum investors buying stocks that were past winners however most did not systematically sell past losers on average funds that invested on momentum realized significantly better performance than other funds the authors also find relatively weak evidence that funds tended to buy and sell the same stocks at the same time copyright 1995 by american economic association

securities transaction taxes an overview of costs benefits and unresolved questions many major developed countries including germany japan and the united kingdom have some form of tax on securities transactions the clinton administration recently considered imposing fees of from 14 on transactions in futures contracts past budgets have considered fees of from 6 to 15 proponents of a securities transaction tax in the u s argue that it would tap into a significant source of revenues and would in addition act to reduce excess volatility in securities markets by discouraging speculative and noise trading some have argued that it would also increase investors expected holding periods hence encourage corporate managers to build for the long term opponents argue that any benefits from such a tax would be overwhelmed by its costs they point out that a tax on transactions would increase the cost of capital reduce market liquidity and bring down security values furthermore as the tax would change the relative costs of holding and issuing different classes of securities it might be expected to change capital structures and investment portfolios too at its worst a securities transaction tax could drive trading in some securities to overseas markets not burdened by taxation the economic and societal distortions resulting from taxation and avoidance would likely be large

financial transaction taxes market composition and liquidity we use the introduction of a financial transaction tax ftt in france in 2012 to test competing theories on its impact we find no support for the idea that an ftt improves market quality by affecting the composition of trading volume instead our results are in line with the hypothesis that a lower trading volume reduces liquidity and in turn market quality consistent with theories of asset pricing under transaction costs we document a shift in security holdings from short term to long term investors finally we find that moderate aggregate effects on market quality can mask large adjustments made by individual agents

on the value of competition in procurement auctions it is commonly stated that ascending price or second price auctions allocate goods e ciently to those who value them most this implies that the more bidders at the auction stage the more e cient the nal allocation we review this statement when bidders have private information both on a private element and a common element while the nal allocation need not be ex post e cient we show that when bidders are ex ante symmetric more competition at the auction yields higher e ciency on expectation when bidders are ex ante asymmetric in particular with respect to the information on the common element the statement need no longer be true

prices rise faster than they fall output prices tend to respond faster to input increases than to decreases this tendency is found in more than two of every three markets examined it is found as frequently in producer goods markets as in consumer goods markets in both kinds of markets the asymmetric response to cost shocks is substantial and durable on average the immediate response to a positive cost shock is at least twice the response to a negative shock and that difference is sustained for at least five to eight months unlike past studies which documented similar asymmetries in selected markets gasoline agricultural products etc this one uses large samples of diverse products 77 consumer and 165 producer goods accordingly the results suggest a gap in an essential part of economic theory as a start on filling this gap the study finds no asymmetry in the resonse of an individual decision maker a supermarket chain to its costs but it finds above average asymmetry where a cost shock is filtered through a fragmented w

sticky prices inventories and market power in wholesale gasoline markets a model with costly adjustment of production and costly inventories implies that wholesale gasoline prices will respond with a lag to crude oil cost shocks unlike explanations that rely upon menu costs imperfect information or long term buyer seller relationships this model predicts that futures prices for gasoline will adjust incompletely to crude oil price shocks that occur close to the expiration date of the futures contract we test and confirm this implication examining wholesale price responses in 188 gasoline markets we also find that firms with market power adjust prices more slowly than do competitive firms consistent with the model

anticipated and unanticipated effects of crude oil prices and gasoline inventory changes on gasoline prices abstract this paper examines the effect of anticipated and unanticipated changes in oil prices and gasoline inventory on us gasoline prices we estimate empirical responses to anticipated and unanticipated changes in oil prices and gasoline inventory and show that gasoline price adjustments are faster and stronger for anticipated changes in oil prices and inventory levels than for unanticipated changes furthermore this difference is statistically significant we use these findings to evaluate the cost of adjustment hypothesis suggested by borenstein and shephard 2002 we also find that there is an asymmetry in the effect of gasoline inventory on gasoline and oil prices this finding complements a well known result that positive and negative changes in oil prices have asymmetric effect on gasoline prices

symmetric or asymmetric oil prices a meta analysis approach 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

are disadvanteged bidders doomed in ascending auctions a bidder is said to be advantaged if she has a higher expected valuation of the auction prize than her competitor when the prize has a common value component a bidder competing in an ascending auction against an advantaged competitor bids especially cautiously and hence the advantaged bidder wins most of the time however contrary to what is often argued a disadvantaged bidder still wins with positive probability even if his competitor s advantage is very large and even if the disadvantaged bidder has the lowest actual valuation ex post therefore the disadvantaged bidder has an incentive to participate in the auction and the presence of a bidder with a small advantage does not have a dramatic effect on the seller s revenue

symmetric or asymmetric price adjustments in the oil market an empirical analysis of the relations between international and domestic prices in the federal republic of germany 1972 89 abstract this paper investigates how german consumer and wholesale prices for gasoline and light heating oil react to changes in the corresponding rotterdam prices monthly data from 1972 to 1989 are employed and the subperiods of the 1970s 1972 to 1979 and 1980s 1980 1989 are distinguished error correction models are estimated to seperate long run equilibrium relations and short run adjustment processes for the 1980s we find rapid symmetric and full adjustment of the german prices to the rotterdam prices whereas during the 1970s we find some asymmetries and at least for gasoline the adjustment processes took considerably more time

the impact of ethanol production on us and regional gasoline markets abstract this study quantifies the impact of increasing ethanol production on wholesale retail gasoline prices employing pooled regional time series data from january 1995 to march 2008 we find that the growth in ethanol production kept wholesale gasoline prices 0 14 gallon lower than would otherwise have been the case the negative impact of ethanol on retail gasoline prices is found to vary considerably across regions the midwest region has the biggest impact at 0 28 gallon while the rocky mountain region had the smallest impact at 0 07 gallon the results also indicate that the ethanol induced reduction in gasoline prices comes at the expense of refiners profits we find a net welfare loss of 0 5 billion from the ethanol support policies in multiple markets

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers

should speculators be taxed a number of economists have supported the taxation of speculation in financial markets we examine the welfare economics of such a tax in a model of a financial market where some agents have superior information and others have a hedging motive we show that a tax on speculators may actually increase speculative profits this occurs if the speculators benefit from less informative prices offsets the cost of the tax the effect on the welfare of other agents depends on how information revelation changes risk sharing opportunities it is possible for the introduction of a tax to cause a pareto improvement copyright 2000 by university of chicago press

transaction taxes and the behavior of the swedish stock market abstract this paper studies the effects of transaction taxes on the behavior of swedish equity returns during the 1980 1987 period sweden provides an excellent laboratory style setting for such a study as taxes were imposed for political purposes rather than to alter the behavior of the stock market volatility did not decline in response to the introduction of taxes although stock price levels and turnover did large proportions of trading activity migrated overseas to london when the tax rate was increased to 2 in 1986

piecewise procurement of a large scale project this paper studies the optimal piecewise procurement of a large scale project in the unique markov perfect equilibrium mpe of the dynamic procurement game it is found that 1 unlike the static setting the procurer s optimal strategy depends on the number of suppliers and more importantly it is nonmonotonic as one more supplier participates in the procurement auction the procurer softens competition in the initial stages by including more cost btypesq while increasing competition in the mature stages 2 this in turn implies that existing suppliers might favor participation of additional suppliers 3 absent scheduling and or resource constraints the procurer prefers to procure the project as one piece if the suppliers technology exhibits constant or increasing returns and no additional suppliers are enticed to bid and 4 the optimal dynamic mechanism can be easily implemented via a sequence of dominant strategy auctions of the vickrey type d 2004 elsevier b v all rights reserved

symmetric transmission of prices in the retail gasoline market in brazil abstract this study aimed to analyze the existence of asymmetric transmission of prices in the brazilian gasoline market following a regional approach using a disaggregated data set for the period between may 2004 and february 2011 the main result finds evidence of symmetric price transmission in retail gasoline market due to price shocks arising from the distributors it is important to highlight that the disaggregation of the data allowed the study to show that the asymmetry is not a national problem but specific to each city and different for each of the regions in brazil

from oil to consumer energy prices how much asymmetry along the way abstract a longstanding question in macroeconomics is whether fuel prices react more to increases than to decreases of the price of oil this paper analyzes the response of weekly gasoline and gasoil prices to oil prices in the u s the euro area and the four largest euro area countries germany france italy and spain using nonlinear impulse response functions and forecast accuracy tests while for the u s both approaches point to the presence of asymmetries in the adjustment of retail prices for the euro area the evidence is mixed

is there an asymmetry in the response of diesel and petrol prices to crude oil price changes evidence from new zealand 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

on the profitability of reducing competition in all pay auctions with risk averse bidders abstract in an all pay auction with risk averse bidders the seller s revenue is decreasing in the number of competitors if either the bidders are very risk averse or the distribution for the valuations attaches probability almost one to a single value

asymmetry in retail gasoline and crude oil price movements in the united states an application of hidden cointegration technique abstract 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

econometric models of asymmetric price transmission abstract in this paper we review the existing empirical literature on price asymmetries in commodities providing a way to classify and compare different studies that are highly heterogeneous in terms of econometric models type of asymmetries and empirical findings relative to the previous literature this paper is novel in several respects first it presents a detailed and updated survey of the existing empirical contributions on price asymmetries in the transmission mechanism linking input prices to output prices second this paper presents an extension of the traditional distinction between long run and short run asymmetries to new categories of asymmetries such as contemporaneous impact distributed lag effect cumulated impact reaction time equilibrium and momentum equilibrium adjustment path regime effect regime equilibrium adjustment path each empirical study is then critically discussed in the light of this new classification of asymmetries third this paper evaluates the relative merits of the most popular econometric models for price asymmetries namely autoregressive distributed lags partial adjustments error correction models regime switching and vector autoregressive models finally we use the meta regression analysis to investigate whether the results of asymmetry tests are not model invariant and find which additional factors systematically influence the rejection of the null hypothesis of symmetric price adjustment the main results of our survey can be summarized as follows i each econometric model is specialized to capture a subset of asymmetries ii each asymmetry is better investigated by a subset of econometric models iii the general significance of the f test for asymmetric price transmission depends mainly on characteristics of the data dynamic specification of the econometric model and market characteristics overall our empirical findings confirm that asymmetry in all its forms is very likely to occur in a wide range of markets and econometric models

testing for price response asymmetries in the spanish fuel market new evidence from daily data abstract in this work we use daily data to examine pattern asymmetries in the speed of transmission of international wholesale oil prices to spanish retail fuel prices results are robust to two alternative specifications of an asymmetric error correction model for which the presence of autoregressive conditional heteroskedasticity for disturbances is modeled by a garch 1 1 process evidence indicates that the short term transmission of wholesale prices to retail prices is quite symmetric for both gasoline and diesel fuel nevertheless in contrast to some of the results provided for an earlier period we did not find asymmetries in the speed of retail price responses toward long run equilibrium our evidence also suggests that the use of weekly or lower frequency data is one of the possible explanations for some of the seemingly contradictory results concerning this issue

lags in the response of gasoline prices to changes in crude oil prices the role of short term and long term shocks abstract using weekly data for the period march 1991 to august 2002 we estimate the response of retail gasoline prices to changes in crude oil and spot gasoline prices in the us allowing for a possibility of two types of cost shocks to the gasoline market long term and short term shocks our conclusion is that theoretical models should be developed that allow more than one type of input price changes and the different effect of input price changes on output prices the empirical results support the conjecture of two types of cost shocks as such we find that lags in the response of retail gasoline prices to changes in crude oil prices may be due to the fact that approximately 97 of changes in crude oil prices are viewed as short term by the market participants when two types of shocks are considered there is large difference between the cumulative response function of gasoline prices to long term and short term shocks to crude oil prices as such this paper adds to our understanding of the price stickiness of gasoline prices

do gasoline prices respond asymmetrically in the euro zone area evidence from cointegrated panel data analysis this paper uses the generalized method of moments gmm estimation to a panel data error correction model ecm in order to measure the asymmetries in the transmission of shocks to input prices and exchange rate onto the wholesale and retail gasoline price respectively for this purpose we use an updated data set of 6369 weekly observations january 2000 to february 2011 for 11 euro zone countries the results indicate the existence of asymmetric responses in the retail and wholesale segment due to possible reasons oligopolistic structure of the refining industry existence of consumers search costs regulatory and legal barriers

transaction costs and asset prices a dynamic equilibrium model in this article we study the effects of transaction costs on asset prices we assume an overlapping generations economy with a riskless liquid bond and many risky stocks carrying proportional transaction costs we obtain stock prices and turnover in closed form surprisingly a stock s price may increase in transaction costs and a more frequently traded stock may be less adversely affected by an increase in transaction costs calculations based on the marginal investor overestimate the effects of transaction costs for realistic parameter values transaction costs have very small effects on stock prices but large effects on turnover

asymmetric fuel price responses under heterogeneity we explore the effect of cross sectional aggregation of data on estimation and test of asymmetric retail fuel price responses to wholesale price shocks the analysis is performed on data collected daily from individual fuel stations in the spanish metropolitan areas of madrid and barcelona while the standard ols estimator is applied to an error correction model in the case of the aggregated time series we use the mean group approaches developed by pesaran and smith 1995 and pesaran 2006 to estimate the short and long run micro relations under heterogeneity we found remarkable differences between the results of estimations using aggregated and disaggregated data which are highly robust to both datasets considered our findings could help to explain many of the results in the literature on this research topic on the one hand they suggest that the typical estimation with aggregated data clearly tends to overestimate the persistence of shocks on the other hand we show that aggregation may generate a loss of efficiency in econometric estimates that is sufficiently large to hide the existence of the rockets and feathers phenomenon

rockets and feathers revisited an international comparison on european gasoline markets this paper re examines the issue of asymmetries in the transmission of shocks to crude oil prices onto the retail price of gasoline relative to the previous literature the distinguishing features of the present paper are i use of updated and comparable data to carry out an international comparison of gasoline markets ii two stage modeling of the transmission of oil price shocks to gasoline prices first refinery stage and second distribution stage in order to assess possible asymmetries at either one or both stages iii use of asymmetric error correction models to distinguish between asymmetries that arise from short run deviations in input prices and from the speed at which the gasoline price reverts to its long run level iv explicit possibly asymmetric role of the exchange rate as crude oil is paid for in dollars whereas gasoline sells for different sums of national currencies v bootstrapping of f tests of asymmetries in order to overcome the lowpower 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

auctions versus negotiations which is the more profitable way to sell a company an auction with no reserve price or an optimally structured negotiation with one less bidder we show under reasonable assumptions that the auction is always preferable when bidders signals are independent for affiliated signals the result holds under certain restrictions on the seller s choice of negotiating mechanism the result suggests that the value of negotiating skill is small relative to the value of additional competition the paper also shows how the analogies between monopoly theory and auction theory can help derive new results in auction theory jel d44 g34 there are close analogies between standard price theory and the theory of auctions in an absolute english auction in which the price rises continuously until only one bidder remains and the seller is required to accept the final bid the sale price equals the lowest competitive price at which supply equals demand in the theory of optimal auctions the seller is treated as a monopolist who can choose any

the economic significance of gasoline wholesale price volatility to retailers abstract we show that gasoline retailer profits heavily depend on the direction of wholesale cost movements using a unique firm level proprietary sample of 121 u s gasoline retailers collectively operating over 4500 stores we find that it tends to be only in months when wholesale prices are declining that retailers make meaningfully positive profits and that in spite of the low profits earned when wholesale prices are increasing over the entire wholesale price cycle volatility is preferred by retailers to relatively stable wholesale prices we are the first to our knowledge to link asymmetric price responses directly to firm profits and characterize the economic significance of asymmetric pricing in the retail gasoline industry our findings may have important implications for the scores of other industries where asymmetric retail to wholesale price responses are found

price asymmetry in the dutch retail gasoline market abstract this article analyses the retail price adjustments in the dutch gasoline market we estimate an asymmetric error correction model on weekly price changes for the years 1996 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 the prices are observed matters more than commonly believed in our view the insufficient robustness of the outcomes might explain the mixed conclusions found in the literature using these two approaches we also show that the effect of asymmetry on the dutch consumer costs is negligible
