price adjustment and market structure a reply1 winters comment essentially concerns the econometric methods used to estimate the adjustment concentration relationship in this reply it will be shown that the suggested estimation methods do not alter our earlier conclusions some new econometric estimates indicate that the original findings should stand without major qualification and consequently winters criticisms of our methodology are unjustified but first the broader question regarding the alleged link between concentration and inflation is examined anyone who reads the paper carefully cannot fail to realise that it is not about inflation what it does is to estimate the relationship between the speed of price adjustment and concentration as a test of the administered prices hypothesis 2 to suggest that the findings could have implications for inflation is entirely different from saying that they explain inflation these implications are twofold first bigger as associated with greater concentration lead to higher shortrun peaks in the rate of inflation following a shock which given the evidence on thresholds in the formation of inflationary expectations could have a significant influence on wage price dynamics 3 second constraints on the rate at which cost increases can be passed on could lead firms to absorb or resist these changes a factor stressed by the monopolies commission 1973 p 30 to which reference was made in the article

industry structure and the speed of price adjustment recent work has suggested that there is an association between the degree of concentration in an industry and the speed at which prices adjust to changes in prime costs cagan 8 domberger 12 13 scherer 21 p 356 and the references cited therein apart from its intrinsic interest to students of industrial economics there would seem to be three reasons for investigating this association first to see what light if any it throws upon the influence of industrial structure on the price level together with the rate and process of inflation secondly to test the assumption made in some influential studies e g godley and nordhaus 15 coutts godley and nordhaus 10 and haig and wood 18 that the size of the lag between cost and price changes is solely dependent upon the length of the fabrication production and delivery period in the various industries the third reason is a belief held by the author that distributed lag coefficients in econometric studies should be subject to analysis and not left hanging in the air as part of the development of a large scale econornetric model of the australian economy the imp model a team of researchers under the direction of dr brain at melbourne university have estimated price prime cost equations for 43 manufacturing sectors using annual data referring to the period 1948 49 1973 74 1 the estimating equation is of the form

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

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

macroeconomic features of the french revolution this paper describes aspects of the french revolution from the perspective of theories about money and government budget constraints we describe how unpleasant fiscal arithmetic gripped the old regime how the estates general responded to reorganize france s fiscal affairs and how fiscal exigencies impelled the revolution into a procession of monetary experiments ending in hyper inflation

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

the theory of sovering debt and spain under philip ii this paper examines lending by a genoese led cartel to philip ii of spain 1556 98 from the perspective of theory on sovereign debt models in this literature suggest that the genoese linked specie deliveries from spain to the low countries to lending in order to create a penalty to enforce their loans the king tried to renege the genoese applied the penalty and the king ultimately repaid when the episode is used to examine theory the crown s observed debt ceiling and estimates of its cost of enduring the penalty and its ability to repay are in line with predctions of bulow and rogoff the nature of the penalty has the flavor of gole and kehoe s model its observation on the path of play is suggestive of atkeson s model

retail price cycles and the presence of small firms abstract in many canadian cities retail gasoline prices remain unchanged for weeks at a time while in other cities retail prices cycle increasing sharply and declining slowly in maskin and tirole econometrica 56 1988 571 both price cycles and rigid prices can exist in equilibrium in this article i demonstrate that the existence of these equilibria is dependent on the number of retail outlets operated by the firms constant price equilibria are found to exist only when firms are of similar size however cycle equilibria can be constructed for a wide range of relative sizes

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

on the distinction between structure and conduct adjustment costs concentration and price behavior the effect of concentration on the speed of price adjustment is studied and shown to be ambiguous when adjustment costs are convex the result relies on making a distinction between the structure of an industry and the conduct of firms within it copyright 1989 by blackwell publishing ltd

market structure and the nature of price rigidity evidence from the market for consumer deposits panel data on consumer bank deposit interest rates reveal asymmetric impacts of market concentration on the dynamic adjustment of prices to shocks banks in concentrated markets are slower to raise interest rates on deposits in response to rising market interest rates but are faster to reduce them in response to declining market interest rates thus banks with market power skim off surplus on movements in both directions since deposit interest rates are inversely related to the price charged by banks for deposits the results suggest that downward price rigidity and upward price flexibility are a consequence of market concentration

the democratic advantage institutional foundations of financial power in international competition despite their presumed liabilities institutions associated with democracy serve as a source of power in prolonged international competition by increasing the financial resources that states can bring to bear the theory of sovereign debt suggests that a state s ability to raise money through public borrowing is enhanced when debtholders have mechanisms for sanctioning state leaders in the event of default institutions associated with liberal government provide such mechanisms all other things being equal states that possess these institutions enjoy superior access to credit and lower interest rates than do states in which the sovereign has more discretion to default unilaterally liberal states can not only raise more money from a given economic base but can also pursue tax smoothing policies that minimize economic distortions the ability to finance competition in a manner that is consistent with long term economic growth generates a significant advantage in prolonged rivalries these claims are explored by analyzing the anglo french rivalry 1688 1815 and the cold war

decentralized coercion and self restraint in provincial taxation the ottoman empire 15th 16th centuries abstract for technological reasons the central administration of a state may want to entrust to provincial delegates the dual tasks of extracting provincial resources and converting them into coercive force this article establishes that the coercive threat that the delegates pose may make the administration cap the amount they extract the cap will cause the state not to internalize the marginal benefits of provincial economic development it will also induce inefficient economic policies the identified institutional setup is consistent with the political regime economic policy and legislation of the ottoman empire during its classical age

channel coordination over time incentive equilibria and credibility abstract the paper studies a channel of distribution consisting of a manufacturer and a retailer in a dynamic game of pricing and advertising the carry over effects of channel member s advertising efforts are summarized in a stock of advertising goodwill each channel member has perfect information about the other channel member s price and advertising effort if each firm employs marketing strategies that are linear functions of the other member s actions and these strategies are jointly carried out a pareto optimal joint profit maximization outcome can be realized the paper also addresses the question of credibility of the incentive strategies

dhsy revisited the role of asymmetries davidson et al s data set is used to demonstrate the existence of a significant asymmetry in the adjustment of consumption towards equilibrium the granger lee and escribano pfann methods of partitioning the error correction term are compared and it is shown that the latter produces better results in this case it is concluded that adjustment is faster under conditions of recession than it is during boom periods

competing for ownership we study how the internal organization of firms specifically the allocation of ownership of assets and the distribution of profi ta mong the firm s managers is determined in a competitive market we ask how scarcity of assets skills or liquidity in the market translates into ownership and control allocations within organizations firms will be more integrated when the terms of trade are more favorable to the short side of the market when liquidity is unequally distributed among existing firms and when there is a positive uniform shock to productivity the model identifies a price like mechanism whereby local liquidity or productivity shocks propagate and lead to widespread organizational restructuring

price adjustments by a gasoline retail chain we use daily data to examine price responses in the swedish gasoline market to changes in the rotterdam spot price exchange rates and taxes the distribution of price adjustments by a leading retail chain for the period january 1980 to december 1996 is symmetric with no small adjustments an error correction model shows that in the short run prices gradually move towards the long run equilibrium in response to cost shocks there is some evidence that also in the short run prices are stickier downwards than upwards prices respond more rapidly to exchange rate movements than to the spot market price our analysis emphasizes that to fully understand price adjustments it is necessary to examine data sets where the sample frequency at least matches that of price adjustments

industrial structure concentration and the speed of price adjustment it is argued that the relationship between market structure and the speed of price adjustment involves two distinct forces with opposing directions t he leadership effect and the industry profitability effect the direction of the relationship will depend on the relative importance of these effects estimation of an equation explaining the speed of price adjustment in terms of industrial concentration and the length of the production period provided evidence of negative effects for bo th the above variables copyright 1988 by blackwell publishing ltd

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

optimal cartel equilibria with imperfect monitoring abstract there exist optimal symmetric equilibria in the green porter model 4 8 having an elementary intertemporal structure such an equilibrium is described entirely by two subsets of price space and two quantities the only production levels used by firms in any contingency the central technique employed in the analysis is the reduction of the repeated game to a family of static games

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

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

price adjustment and market structure abstract this paper shows how the extent of price inertia depends on the form of market competition we first establish that the speed of price adjustment depends on the curvature of the profit function in the region around the optimum price we then show how this depends on market structure we prove the following results 1 1 the speed of price adjustment depends positively on the price elasticity of demand 2 2 the speed of price adjustment depends positively on the number of firms in a market and 3 3 the speed of price adjustment depends negatively on the degree of collusion between firms

sustainable plans and debt abstract this paper presents a simple general equilibrium model of optimal fiscal policy similar to that of lucas and stokey j monet econ 12 1983 55 93 except that we let the government default on its debt we consider sustainable equilibria in which both government and private agent decision rules are required to be sequentially rational we concentrate on trigger mechanisms which specify reversion to the markov equilibrium after deviations by the government and show that such mechanisms cannot support equilibria with positive debt we go on to show by way of examples that there can be more complicated trigger mechanisms which support positive debt journal of economic literature classification numbers e61 e62

international lending with moral hazard and risk of repudiation in this paper i examine the constrained optimal pattern of capital flows between a lender and a borrower in an environment in which there are two impediments to forming contracts the first impediment to contracting arises from the assumption that lenders cannot observe whether borrowers invest or consume borrowed funds this assumption leads to a moral hazard problem in investment the second impediment arises from the assumption that the borrower as a sovereign nation may choose to repudiate his debts the optimal contract is shown to specify that the borrowing country experience a capital outflow when the worst realizations of national output occur this seemingly perverse capital outflow forms a necessary part of the optimal solution to the moral hazard problem in investment

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
