the impact of market structure on wages fringe benefits and turnover this paper examines the relationship between labor compensation and the structure of the product market which is measured by the industry concentration ratio and by dummy variables for the existence and type of government regulation unlike previous studies that have estimated the impact of concentration and regulation on wages or earnings this study extends the analysis to include the effect of market structure on employer provided pensions and insurance and on voluntary labor turnover the hypothesis that product market power raises labor compensation is supported by empirical results indicating that concentration increases wages and fringes but lowers voluntary labor turnover regulations that set minimum prices and restrict entry raise labor compensation since wage premiums due to regulation are not offset by lower pensions and insurance or higher turnover other forms of regulation such as profit regulation in public utilities are found to reduce labor compensation as evidenced by higher turnover or lower wages and fringes or both

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

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

retail fuel price adjustment in germany a threshold cointegration approach abstract 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

environmental compliance by firms in the manufacturing sector in mexico abstract to date little empirical evidence exists to help regulators understand why some firms comply even when there is little financial incentive to do so and others continually violate environmental regulations this paper examines data on compliance with environmental regulations within the manufacturing sector in mexico the probability of complying depends among other factors on the kind of management practices of the firm and the level of environmental training some firms in the manufacturing sector over comply with regulations our results show that providing environmental training to employees in the firm increases the probability of over compliance local community has a positive impact on over compliance however the magnitude of its impact is not as strong as is often suggested in the literature

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

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

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

making economic policy in weak democratic post crisis states an indonesian case study summary economic crises in developing countries differ in their causes severity and recovery trajectories the literature on the causes and immediate management of these crises is well developed however it is more difficult to develop an a priori framework which facilitates an analytical interpretation of how crises affect economic policy and hence recovery this is especially so in the commonly occurring twin crises in which an economic crisis interacts with regime collapse country studies are needed to contribute to the development of such a framework this paper addresses these issues with reference to indonesia s deep economic and political crisis of 1997 98

oil and gas markets in the uk evidence from a cointegrating approach the paper examines the relationship between uk wholesale gas prices and the brent oil price over the period 1996 2003 in order to investigate whether oil and gas prices decoupled during this period as orthodox gas market liberalisation theory suggests tests for unit roots and cointegration are carried out and it is discovered that a long run equilibrium relationship between uk gas and oil prices exists moreover this relationship pre dates the opening of the uk mainland europe interconnector following a recursive methodology hansen h and johansen s 1999 some tests for parameter constancy in cointegrated var models econometrics journal 2 306 333 it was found that the cointegrating relationship is present throughout the sample period however the long run solutions seem to be more volatile evidence is provided that the short run relationship is linear and impulse response functions are used to examine the effects that a shock in oil would have on gas these findings do not support the assumption that gas prices and oil prices decouple

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

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

estimating wage discrimination in the labor market if labor supply curves are not perfectly inelastic wage discrimination induces some minority workers to leave the labor force studies of discrimination that focus only on wage differentials overlook these disincentive effects on minority employment

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

sex discrimination and competition in product and labour markets theoritical explanations for wage discrimination collapse in the long run because competition should drive discriminations firms out of the market in product markets with imperfect competition em

another perspective on gasoline price responses to crude oil price changes the effects of oil price volatility on the responses of gasoline prices to oil price shocks have received little attention in discussions on the relationship between the prices of crude oil and gasoline in this paper we consider such effects by using a bivariate structural vector autoregression which is modified to accommodate garch in mean errors our measure of oil price volatility is the conditional variance of the oil price change forecast error we isolate the effects of volatility in the price of oil on the price of gasoline and employ simulation methods to calculate nonlinear impulse response functions nirfs to trace any asymmetric effects of independent oil price shocks on the conditional means of gasoline prices we test whether the relationship between the prices of crude oil and gasoline is symmetric using tests of the null hypothesis of symmetric impulse responses based on monthly u s data over the period from 1978 1 to 2014 11 our empirical results show that gasoline prices respond asymmetrically to positive and negative oil price shocks we also find that oil price volatility has a positive effect on the price of gasoline and it contributes to the asymmetries in the transmission of oil price shocks

the asymmetric response of gasoline prices to oil price shocks and policy uncertainty abstract this study shows that the effect of oil price shocks on the real price of gasoline is interrelated with economic policy uncertainty economic policy shocks are linked with increased real price of gasoline and reduced consumption of gasoline there is evidence that the fluctuation of both real gasoline prices and of gasoline consumption is associated with uncertainty of tax legislation expiration expectation as well as other components of economic policy uncertainty positive shocks to economic policy uncertainty have relatively larger effects on gasoline prices than do negative shocks to economic policy uncertainty economic policy uncertainty responds asymmetrically to increases and decreases in real oil price shocks to economic policy uncertainty account for 16 1 of variation in real gasoline prices and for 4 9 of variation in gasoline consumption in the long run

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

discrete devaluations and multiple equilibria in a first generation model of currency crises the flrst generation models of currency crises have often been criticized because they predict that in the absence of very large triggering shocks currency attacks should be predictable and lead to small devaluations this paper shows that these features of flrst generation models are not robust to the inclusion of private information in particular this paper analyzes a generalization of the krugman flood garber kfg model which relaxes the assumption that all consumers are perfectly informed about the level of fundamentals in this environment the kfg equilibrium of zero devaluation is only one of many possible equilibria in all the other equilibria the lack of perfect information delays the attack on the currency past the point at which the shadow exchange rate equals the peg giving rise to unpredictable and discrete devaluations

concentration and the inter industry wage structure the israeli manufacturing sector the paper analysis the inter industry wage differentials in the israeli manufacturing sector in conjunction with differences in the degree of competition in the various industries unlike some other studies carried out with us date that did not produce conclusive results this study shows a clear cut positive relationship between wages and the degree of monopolization this result is found both for unskilled and highly skilled workers

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

financial crisis health outcomes and aging mexico in the 1980s and 1990s abstract we study the impact of economic crisis on health in mexico there have been four wide scale economic crises in mexico in the past two decades the most recent in 1995 96 we find that mortality rates for the very young and the elderly increase or decline less rapidly in crisis years as compared with non crisis years in the 1995 96 crisis mortality rates were about 5 to 7 percent higher in the crisis years compared to the years just prior to the crisis this translates into a 0 4 percent increase in mortality for the elderly and a 0 06 percent increase in mortality for the very young we find tentative evidence that economic crises affect mortality by reducing incomes and possibly by placing a greater burden on the medical sector but not by forcing less healthy members of the population to work or by forcing primary caregivers to go to work

oil and pump prices testing their asymmetric relationship in a robust way abstract the aim of this study is to provide a novel method to assess whether retail fuel prices respond asymmetrically to changes in the international crude oil prices to do so we consider the whole supply chain we use daily data and we depart from the current practice in the literature that focuses on prices rather we consider the mark ups of both the refineries and retailers hence we show that we first need to assess whether the refineries mark up responds asymmetrically to the international crude oil prices and subsequently whether the retailers mark up shows an asymmetric behaviour relatively to changes in the refined fuel prices focusing in greece as our case study our findings show that greek fuel retailers do not change their mark up behaviour based on changes of the refined fuel price by contrast the asymmetric behaviour is evident in the refineries mark up relatively to changes in the international crude oil prices which is then passed through to the retailers and consumers finally we provide evidence that weekly and monthly data mask any such asymmetric relationship thus we maintain that unless the appropriate data frequency fuel price transformations and the whole supply chain are considered misleading findings could be revealed

price rigidity in the downstream petroleum industry in new zealand where does it happen 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

whither the nonprofit wage differential estimates from the 1990 census this article provides new estimates of the nonprofit for profit wage differential in the u s economy using observations on 4 1 million private sector employees from the 1990 census i find either zero or slightly positive economy wide wage differences between nonprofit and for profit employees in a standard earnings equation format significant wage differentials are found at the disaggregated occupation and industry level and provide a basis for testing hypotheses explaining nonprofit for profit wage differences

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

another look on the relationships between oil prices and energy prices this paper employs the quantile autoregressive distributed lags qardl model developed recently by cho et al 2015 to investigate the pass through of oil prices to a set of energy prices this approach allows analyzing simultaneously short term connections and long run cointegrating relationships across a range of quantiles it also provides insights on the short run predictive power of oil prices in predicting energy prices while accounting for the cointegration between oil prices and each of the considered energy prices in low medium and high quantiles two key findings emerge from this paper first all considered energy prices are shown to be cointegrated with oil price across quantiles meaning that a stationaryequilibriumrelationship exists between single energy price and oil price second we find evidence that oil price is a significant predictor of individual petroleum products prices and natural gas in the short run this paper has important policy implications for forecasters energy policy makers and portfolio managers

asymmetric price adjustments in us gasoline markets impacts of spatial dependence on the rockets and feathers hypothesis gasoline retail prices show sometimes wild asymmetric fluctuations over time we explore the impact of spatial dependence on gasoline retail price formation by using for the first time an asymmetr

higher prices at canadian gas pumps international crude oil prices or local market concentration an empirical investigation there is little consensus on whether higher retail gasoline prices in canada are the result of international crude oil price fluctuations or local market power exercised by large vertically integrated firms i find that although both increasing local market concentration and higher average monthly wholesale prices are positively and significantly associated with higher retail prices wholesale prices are more important than local market concentration similarly crude oil prices are more important than the number of local wholesalers in determining wholesale prices these results suggest that movements in gasoline prices are largely the result of input price fluctuations rather than local market structure

asymmetric pass through of oil prices to gasoline prices evidence from a new country sample abstract this paper investigates the asymmetric pass through of oil prices to gasoline prices under the non linear autoregressive distributed lags nardl model the analysis adds to the unsettled discussion of whether retail gasoline prices respond asymmetrically to oil prices and it is carried out for the us the uk spain italy and greece spanning the period january 2009 to july 2016 these countries have been selected on the basis that fuel markets are differentiated by the structure of retail markets oligopolistic behavior production lags and market competition which depends on extraction refinery and distribution the analysis considers markets that differ in terms of their structure both short and long run non linearity are tested by deriving both the positive and negative partial sum decompositions of the dependent variable in addition it was feasible to quantify the responses to positive and negative oil price shocks from the asymmetric dynamic multipliers the findings indicate that oil and gasoline prices provide mixed evidence of an asymmetric behavior short run asymmetry is found in the italian market while in the spanish market there is evidence of both short and long run asymmetry the remaining cases greece u k u s illustrate a symmetric pass through scheme of oil to retail gasoline prices

do gasoline prices exhibit asymmetry not usually 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

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

reassessing the male female wage differential a fixed effects approach the vast literature on the subject of the male female wage differential has shown that despite dramatic structural and behavioral changes in the labor supply of women a sizeable wage differential exists 19 2 9 6 4 o neill 16 s92 finds that a sex differential of about 40 as measured by full time annual earnings has persisted in the u s for the last four decades but while few doubt the existence of the wage gap there is considerable controversy regarding the role of the factors explaining the gap the conventional approach of economists has been to estimate earnings as a function of various socio economic characteristics the observed wage gap is decomposed into a part explained by productivity related factors and an unexplained residual traditionally labelled as discrimination while it is possible that the unexplained variation in earnings is the result of discrimination it is also possibly the result of model misspecification 2 in this present paper we address the misspecification that could possibly arise from omitted variables endogeneity and sample selection while these issues have been considered in the context of women s labor supply functions they have largely been ignored in studies on the wage differential 12 13 we approach the problem of omitted variables by formulating a fixed effects model in this way productivity related factors that are difficult to measure or have unsuitable proxies are netted out from the earnings equation furthermore some of the variables that are used to explain wages are themselves the outcome of discrimination in particular the labor market experience of a woman is dependent on her wages earned here we address the endogeneity that such a cause and effect relationship may bring about a third difficulty arises because a typical sample of working women is a non random selection of the female labor force giving rise to the problem of sample selection bias heckman s 12 213 17 procedure is used to formulate a sample selection model of earnings the organization of this paper proceeds as follows section ii begins with the traditional model of earnings and then develops an extended model which consolidates the issues of omitted variables endogeneity and sample selection section iii contains the empirical results of the

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

new evidence on asymmetric gasoline price responses in a 1997 paper borenstein cameron and gilbert bcg claim that gasoline prices rise quickly following an increase in the price of crude oil but fall slowly following a decrease this note estimates an error correction model with daily spot gasoline and crude oil price data over the period 1985 1998 and finds no evidence of asymmetry in wholesale gasoline prices the sources of the difference in results are twofold first we use the standard engle granger two step estimation procedure whereas bcg used a nonstandard estimation methodology second even using bcg s nonstandard specification the use of daily rather than weekly data yields little evidence of price asymmetry

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

earnings differentials and market structure theoretical models suggest that market structure may influence the magnitude of earnings differentials and or discrimination observed in the marketplace empirical results with regard to wage differentials and labor force participation patterns have been mixed most wage differential studies have focused on males due to difficulty in obtaining reliable data for women and to the sample selection problem of women s labor force participation decisions this paper characterizes market structure by four categories regulated nonprofit government and nonregulated industries within these structural categories earnings differentials are examined for men and women adjusting for race occupational stratification and sample selection bias

the pass through of oil prices into euro area consumer liquid fuel prices in an environment of high and volatile oil prices abstract crude and refined oil prices have been relatively high and volatile on a sustained basis since 1999 this paper considers the pass through of oil prices into consumer liquid i e petrol diesel and heating fuel prices in such an environment the pass through of oil prices into consumer liquid fuel prices has already been addressed extensively in the literature nonetheless much of this literature has either focused on the united states or on a time period when oil prices were relatively stable or has used monthly data the main contribution of this paper is a comprehensive combination of many features that have been considered before but rarely jointly these features include 1 the analysis of the euro area as an aggregate and a large number of countries the initial 12 member states 2 the consideration of different time periods 3 the modelling of the data in raw levels rather than in log levels this turns out to have important implications for our findings 4 the use of high frequency weekly data which as results will suggest are the lowest frequency one should consider 5 the investigation of the different stages of the production chain from crude oil prices to retail distribution refining costs and margins distribution and retailing costs and margins 6 the examination of prices including and excluding taxes excise and value added 7 the modelling of prices for three fuel types passenger car petrol and diesel separately and home heating fuel oil 8 lastly we also address the issue of possible asymmetries allowing for the pass through to vary according to a whether price are increasing or decreasing and b whether price levels are above or below their equilibrium level the main findings are as follows first as distribution and retailing costs and margins have been broadly stable on average the modelling of the relationship between consumer prices excluding taxes and upstream prices in raw levels rather than in logarithms has important implications for the stability of estimates of pass through when oil price levels rise significantly second considering spot prices for refined prices improves significantly the fit of the estimated models relative to using crude oil prices it also results in more economically meaningful results concerning the extent of pass through third oil price pass through occurs quickly with 90 occurring within three to five weeks fourth using a relatively broad specification allowing for asymmetry in the pass through from upstream to downstream prices there is little evidence of statistically significant asymmetries furthermore even where asymmetry is found to be statistically significant it is generally not economically significant lastly these results generally hold across most euro area countries with few exceptions

compensation in the nonprofit sector we investigate the determinants of pay in the nonprofit sector using data for 25 55 year olds from the 1994 88 current population survey outgoing rotation groups our results are consistent with the hypothesis that compensation is primarily determined in competitive markets without labor donations to nonprofit employers one implication is that nonprofit workers receive virtually the same wages as observationally equivalent employees in similar positions with profit seeking enterprises we cannot rule out the possibility of nonprofit penalties or premiums for selected groups however the differentials are generally small and competition appears to play a dominant role in nonprofit wage setting

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

retail price asymmetries in local gasoline markets the experience of the salt lake city retail gasoline market during the 1989 to 1993 period suggests that there was asymmetric adjustment wholesale and retail price data unique to the salt lake market are used to test for the existence of three types of price asymmetry during this period with respect to the magnitude of the pass through of wholesale price changes evidence of price asymmetry during periods of average weekly wholesale price changes is found however during market shocks the evidence points in the direction of retail price symmetry evidence of asymmetry with respect to the timing and pattern of the retail price response is found for periods of both average and market shock changes since gasoline is purchased by the consumer in local markets conclusions reached by studies of market pricing behaviour that rely on national data may not be relevant for local policy decisions this appears to be the case for the salt lake city market

rockets and feathers meet joseph reinvestigating the oil gasoline asymmetry on the international markets abstract we reinvestigate the rockets and feathers effect between retail gasoline and crude oil prices in a new framework of fractional integration long term memory and borderline non stationarity the most frequently used error correction model is examined in detail and we find that the prices return to their equilibrium value much more slowly than would be typical for the error correction model such dynamics is usually referred to as the joseph effect the standard procedure is shown to be troublesome and we introduce two new tests to investigate possible asymmetry in the price adjustment to equilibrium under these complicated time series characteristics on the dataset of seven national gasoline prices we find no statistically significant asymmetry the proposed methodology is not limited to the gasoline and crude oil case but it can be utilized for any asymmetric adjustment analysis

competition small business financing and discrimination evidence from a new survey we analyze credit applications loan denials and interest rates paid by small businesses across owner gender race and ethnicity in addition we examine data from owners who said they did not apply for credit because they believed that their applications would have been turned down after controlling for a rich set of explanatory variables including personal and business credit histories substantial differences in denial rates between firms owned by african americans and white males remain moreover consistent with becker s classic theories 1957 we find evidence that increases in competition in the firm s local banking market reduces these differences

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
