price wars in price setting supergames this paper presents a method of generating price wars in price setting supergames the market is one where symmetric oligopolists produce a differentiated product and use price as a strategic variable prices are posted and can be observed by all there is thus little uncertainty or scope for secret price cutting nevertheless price wars occur they are precipitated by periodic but infrequent demand shocks firms use the wars to learn about changed conditions in the market so that they can calculate the new stationary nash equilibrium learning is modeled in a bayesian fashion via the kalman filter copyright 1989 by the london school of economics and political science

uncovering financial market expectations of inflation this paper seeks to uncover market expectations of inflation from the joint dynamics of nominal interest rates and observed inflation i postulate 1 the existence of a stable vector autoregression in unobserved variables and 2 efficient financial markets the estimation procedure requires no further structural assumptions the econometrician need not observe all the information used by agents in forming forecasts or all the variables that influence real interest rates i find no empirical evidence that economic recessions are correlated with inflation forecast errors however postwar recessions are associated with ex ante real interest rates that are twice the postwar average

a study of cartel stability the joint executive committee 1880 1886 this article employs weekly time series data on the joint executive committee railroad cartel from 1880 to 1886 to test empirically the proposition that observed prices reflected switches from collusive to noncooperative behavior an equilibrium model of dynamic oligopoly with asymmetric firms together with explicit functional form assumptions about costs and demand determines the estimating equations and stochastic structure of the econometric model the hypothesis that no switch took place so that price and quantity movements were solely attributable to exogenous shifts in the demand and cost functions is then tested against this alternative and rejected

empirical studies of gasoline retailing a guide to the literature abstract this paper surveys the empirical literature on gasoline retailing which has been growing rapidly over the last three decades possibly in response to antitrust and regulatory concerns and increased availability of pricing data studies of both pricing and non price decision variables are considered in general it is found that crude oil prices are the primary driver of national price movements over time however market structure has been identified as playing a role in price dynamics equilibrium selection and price differentials across markets and stations the economic literature emphasizes the importance of heterogeneity across stations and coordination problems faced by retailers several directions for future work are suggested including the development of theory and demand estimation using high frequency station level data

strategic pricing models and interpretation of price war data abstract price wars cartel breakdowns and other seemingly disequilibrium pricing phenomena are examined questions of interest include when do breakdowns occur how long do they last what determines their severity and are they characterized by increased cross sectional price dispersion and or temporal price volatility the first half of the paper explains how the choice of punishment strategy the specification of the stochastic shocks to the system and the assumptions regarding observability determine the pricing dynamics implicit in several theoretical price war models theories are classified into imperfect monitoring models in which players actions cannot be observed learning models in which structural parameters are unknown to the players and cyclical models in which observability is perfect but business cycles affect the difficulty of colluding the second half in contrast examines data on prices actually set by firms in industries which are subject to periodic wars when the models are confronted with the data we can see how well oligopoly theory explains the behavior of the firms in these industries the object of the exercise is not to pick a winner instead the role of industry characteristics in determining pricing dynamics is assessed and the reasons why simple models may fail to explain complex pricing patterns are examined finally directions for future research are suggested by the empirical regularities which are uncovered

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

vertical relationships an introduction this short essay introduces a special issue of the journal of industrial economics on vertical relationships including both vertical integration and vertical restraints in the last few years there has been a resurgence of theoretical and empirical work on vertical relationships and they are central to major current issues in industrial policy in this introduction the authors briefly describe the contribution by the papers that make up this special issue copyright 1991 by blackwell publishing ltd

when does a central bank s balance sheet require fiscal support abstract using a simple general equilibrium model we argue that it would be appropriate for a central bank with a large balance sheet composed of long duration nominal assets to have access to and be willing to ask for support for its balance sheet by the fiscal authority otherwise its ability to control inflation may be at risk this need for balance sheet support a within government transaction is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank s balance sheet is merged with that of the rest of the government

spatial differentiation and vertical mergers in retail markets for gasoline this paper studies an empirical model of spatial competition applied to gasoline markets the main feature is to specify commuting paths as the locations of consumers in a hotelling style model as a result spatial differentiation depends in an intuitive way on the structure of the road network and the direction of traffic flows the model is estimated using panel data on the quebec city gasoline market and used to evaluate the consequences of a recent vertical merger difference in difference and counterfactual simulation methods are compared and the results to a large extent validate the assumptions of the demand model jel g34 l13 l42 l81 q41 r41

vertical relationships and competition in retail gasoline markets empirical evidence from contract changes in southern california comment this study examines how much if any of the differences in retail gasoline prices between markets is attributable to differences in the composition of vertical contract types at gasoline stations in each market the purchase of the independent retail gasoline chain thrifty by arco provides a unique opportunity to examine the effects of changes in different vertical contract types on local retail prices this event caused sharp changes in the market share of i fully vertically integrated stations and ii independent stations differentially affecting local markets in the los angeles and san diego metropolitan areas using unique and detailed station level data this study examines how these sharp changes affected local retail prices the detailed data and the research design based on the thrifty station conversions allow for credible estimation of the effects of the market share of independent retailers and vertically integrated retailers on local market prices controlling for any omitted factors at the station level and the city level over time results for the los angeles and san diego metropolitan areas indicate that a decrease in the market share of independent stations has a significant positive impact on local retail price however a change in the market share of refiner owned and operated branded stations does not have a significant impact on local market price these results have important implications as policy makers consider the regulation of vertical contracts as a means to increase competition in gasoline markets the research design and detailed data also allow for inference on the underlying nature of retail gasoline competition

subgame perfect reaction function equilibria in discounted duopoly supergames are trivial abstract this paper is concerned with infinitely repeated duopoly games with discounting a question which has been open since friedman s rev econ stud 35 1968 257 272 reaction function article is settled for a general class of games the question is wheter nontrivial reaction function equilibria can be subgame perfect this question is answered in the negative such equilibria must be trivial in the sense of prescribing the stage game noncooperative equilibrium actions in every period independent of prior history

mergers coordinated effects and efficiency in the portuguese non life insurance industry we evaluate the impact on market power and efficiency of a series of mergers on three portuguese non life insurance markets we specify and estimate with a panel of firm level data a structural model which includes preferences technology and a market equilibrium condition firms demand curves are not very elastic firms technologies exhibit scale and scope economies and high cost efficiency scores we find that for the period following the mergers there is no evidence of i an increase in market power through coordinated behavior or ii changes in cost efficiency levels in addition social welfare increased

dynamic pricing in retail gasoline markets supergame models of tacit collusion show that supportable price cost margins increase with expected future collusive profits ceteris paribus as a result collusive margins will be larger when demand is expected to increase or marginal costs are expected to decline using panel data on sales volume and gasoline prices in 43 cities over 72 months we find behavior consistent with tacit collusion in retail gasoline markets controlling for current demand and cost current margins increase with expected next month demand and decrease with expected next month cost the results are not consistent with intertemporal l inkages due to inventory behavior or customer loyalty

a non standard monetary policy shock the ecb s 3 year ltros and the shift in credit supply abstract we study the macroeconomic effects of the 3 year long term refinancing operations ltros introduced by the ecb in december 2011 with the aim of reducing the obstacles to credit supply through the mitigation of liquidity and funding risks in the euro area banking system therefore we interpret the measure as a credit supply shock which is identified both recursively and with sign restriction methods using the euro area bank lending survey bls the size of the shock due to the ltros is computed using both the april 2012 bls and the special ad hoc questions on the ltros conducted in february 2012 the counterfactual exercises suggest that the 3 year ltros lifted prospects for real gdp and loan provision to non financial corporations and increased goods prices over the next two to three years thereby avoiding a major credit crunch

market reactions to ecb policy innovations a cross country analysis abstract regulators have been paying increasing attention to governing and steering market fluctuations with their role in shaping the economic cycle being ever more crucial the combined effect of the financial and sovereign debt crises as well as the approach to the zero lower bound has made actions even more pressing forcing the european central bank to resort to unconventional instruments to revive the economies and counter deflationary pressures by using a combined event study and panel regression methodology we investigate whether european monetary union equity markets react heterogeneously to standard and non standard european central bank policy innovations our results show that conventional policies unevenly affect financial indices in the eurozone and hence are bound to generate asymmetries that reflect on real economies while unconventional measures albeit with different intensities exercise a homogeneous pressure on all markets our evidence highlights the beneficial impact of unconventional measures and suggests that they can play a useful role even in non crisis times

inflation real returns and capital investment we find evidence for the hypothesis of mundell 1963 and tobin 1965 that the expected real return component of interest rates is negatively related to the expected inflation component in the mundell tobin model the variation in expected real returns is caused by the variation in expected inflation our evidence suggests however that the variation in expected real returns is more fundamentally an outcome of the capital expenditures process equilibrium expected real returns vary directly with capital expenditures in order to induce equilibrium allocations of resources between consumption and investment this positive relation between expected real returns and real activity which comes out of the real sector combines with a negative relation between expected inflation and real activity which is traced to the monetary sector thus inducing the negative relation between expected inflation and expected real returns predicted by mundell and tobin but explained in terms of a model much different from theirs

the competitive impact of hypermarket retailers on gasoline prices abstracthypermarkets are large retail suppliers of general merchandise or grocery items that also sell gasoline often at very low margins this paper estimates the impact of hypermarkets on average state level retail gasoline prices and margins the empirical results indicate an economically and statistically significant price decreasing effect of increased hypermarket competition the estimations also suggest that refiners lower the delivered wholesale prices charged to their affiliated lessee dealer and open dealer stations in response to increased hypermarket competition which in turn translates to lower retail street prices the adoption of sales below cost laws may lessen the price reducing effects from hypermarket competition

incidence of federal and state gasoline taxes the federal specific gasoline tax falls equally on consumers and wholesalers whereas state specific taxes fall almost entirely on consumers the consumer incidence of state taxes is greater in states that use relatively little gasoline

conjectures firm characteristics and market structure abstract this paper makes use of a unique data set to investigate how firms in the vancouver british columbia retail gasoline market view their rivals and how consumers in turn view these firms own and rival price elasticities of demand conjectural variations and lerner indices are estimated for thirteen service stations in a submarket of vancouver these variables are then related to firm characteristics such as type of ownership degree of horizontal and vertical integration and type of service in this way systematic patterns in seller behavior and in buyer attitudes are revealed

vancouver s gasoline price wars an empirical exercise in uncovering supergame strategies this paper uses a unique data set to determine which dynamic model of tacit collusion best describes behaviour in a particular industry the area investigated is a region of the vancouver british columbia retail gasoline market players are service station managers who compete daily firms choose price in each period using strategies that depend on prices chosen in the previous period periodically unanticipated demand shocks precipitate price wars when shocks occur the firms in the market must determine the new demand conditions and adjust their strategies from an econometric point of view slopes of intertemporal reaction functions are latent variables the resulting system of equations with time varying parameters is estimated via the kalman filter different repeated game oligopoly models correspond to different transition matrices for the latent variables the models can thus be assessed in terms of their power to explain firm behaviour in this market

the european sovereign debt crisis the origin and propagation of the european sovereign debt crisis can be attributed to the flawed original design of the euro in particular there was an incomplete understanding of the fragility of a monetary union under crisis conditions especially in the absence of banking union and other european level buffer mechanisms moreover the inherent messiness involved in proposing and implementing incremental multicountry crisis management responses on the fly has been an important destabilizing factor throughout the crisis after diagnosing the situation we consider reforms that might improve the resilience of the euro area to future fiscal shocks

the unconventional monetary policy of the european central bank effectiveness and transmission analysis since the beginning of the financial crisis in summer 2007 the european central bank ecb has redirected traditional monetary policy based on interest rates to an unconventional monetary policy focused on the quantitative expansion of its balance sheet in this context the present paper aims to assess the effectiveness of unconventional monetary policy instruments with regard to inflation and economic growth to this end the methodology is based on the estimation of a structural vector autoregressive model for the period 2007 q1 2018 q4 using four variables eonia the total amount of assets on the ecb s balance sheet the eurozone inflation rate and the eurozone economic growth rate the results show a slight impact of the different balance sheet policies on inflation and economic activity behaviour especially during the last year of the financial crisis the robustness of these results is supported by the estimation of the same model replacing eonia rates with shadow rates therefore the results support the existence of monetary transmission for the period during which the unconventional monetary policy was developed as well as the effectiveness of the monetary policy adopted by the ecb in its commitment to price stability

spatial price competition a semiparametric approach we investigate the nature of price competition among firms that produce differentiated products and compete in markets that are limited in extent we propose an instrumental variables series estimator for the matrix of cross price response coefficients demonstrate that our estimator is consistent and derive its asymptotic distribution our semiparametric approach allows us to discriminate among models of global competition in which all products compete with all others and local competition in which products compete only with their neighbors we apply our semiparametric estimator to data from u s wholesale gasoline markets and find that in this market competition is highly localized

the euro crisis the crisis in greece and other mainly southern eurozone countries has been discussed primarily as a fiscal issue current account deficits of the same countries have received less attention in spite of the relatedness of current account and fiscal deficits we argue that the failure of many countries within the eurozone to develop adequate internal adjustment mechanisms is also an important factor behind the crisis after reviewing the major perspectives that have been offered on the crisis we present data that support our argument by demonstrating the lack of price and cost convergence in the eurozone since 1999 ironically it seems that the surplus countries have carried out more of the adjustment pointed to by the endogenous optimum currency area oca theory than the deficit countries we recommend that the responsibility of a european debt surveillance authority should include surveillance of intra euro payment flows imbalances and adjustment in labour and goods markets and setting benchmarks for the eurozone guarantees of sovereign debt based on ability to adjust internally thereby a potential moral hazard problem of an implicit eurozone guarantee of countries sovereign debt could be avoided

do gasoline mergers affect consumer prices the marathon ashland petroleum and ultramar diamond shamrock transaction abstract in 1999 marathon ashland petroleum map acquired the michigan assets of ultramar diamond shamrock uds which increased map s share of terminal storage in michigan from about 16 percent to about 25 percent and increased the share of gasoline stations bearing a map brand from about 16 percent to about 24 percent in this paper we examine whether this acquisition affected the retail price of gasoline we use a difference in differences model to compare price movements in six michigan cities affected by the acquisition with price movements in two nearby cities unaffected by the acquisition using this model we find no evidence that this acquisition led to higher prices for consumers

the price and profit effects of horizontal merger a case study the economic rationale behind antitrust concern for horizontal mergers rests primarily on the familiar structure performance paradigm that links market concentration with supra competitive profits and implicitly with higher prices a vast empirical literature has demonstrated a positive statistical relationship between measures of industry structure such as entry barriers and concentration and average industry profit using cross section data a small number of cross section studies most dealing with banking services have claimed to find a positive relationship between concentrated market structure and price measures aspinwall 1970 bell and murphy i969 heggestak and mingo 1976 hester i979 lamm i98i landon i97i marion et al 1979 and marvel 1978 but we are unaware of any study that traces the effect of an actual change in market structure on prices or profits in this paper we exploit an unusual opportunity to test for price effects and estimate profit consequences of two acquisitions that resulted in substantial increases in the market share of the acquiring firm the evidence we examine arises from a recent federal trade commission antitrust suit against xidex corporation the world s largest producer of duplicating microfilm the xidex case is unusual in three respects i although the size of the market is small sales under ioo million the acquisitions involved greater changes in market shares than are usual in antitrust actions 2 the suit was brought five years after the first acquisition and two years after the second so a post acquisition record of price behavior exists for this example furthermore the price data used in this study are actual transaction prices 3 special characteristics of the products allow a relatively straightforward test for price effects of the acquisitions the next section provides background information concerning the firms and products involved following that we describe the data and methodology used to estimate the price effects of the acquisitions and present results which indicate significant price increases traceable to the acquisitions we then offer estimates of the incremental profits attributable to those price increases a final section provides a summary the analysis and conclusions set forth in this study are those of the authors and do not necessarily reflect the views of federal trade commission staff or the commission itself all data and other information used in the study are in the public domain this includes information obtained by the commission which has become part of the public record for helpful comments we thank allan fisher ron lafferty paul pautler and rich sciacca of the bureau of economics federal trade commission

market power vertical integration and the wholesale price of gasoline this paper examines empirically the relationship between vertical integration and wholesale gasoline prices we use discrete and differential changes in the extent of vertical integration generated by mergers in west coast gasoline refining and retailing markets to test for incentives to raise rivals costs the research design allows us to test for a relationship between vertical integration and wholesale prices controlling for horizontal market structure cost shocks and trends we find evidence consistent with the strategic incentive to raise competitors input costs this suggests that vertical integration can have a significant impact on wholesale prices

the effectiveness of the ecb s unconventional monetary policy comparative evidence from crisis and non crisis euro area countries abstract during the european financial crisis the european central bank implemented a series of unconventional monetary policy measures we argue that these programs lowered the bond yield spreads of euro area countries this hypothesis is tested using pooled ols estimations and two different datasets monetary policy event dummies and the purchase volumes of the securities markets programme smp overall we find significantly negative effects on bond yield spreads for both datasets leading us to accept the hypothesis while the omt reduces the spreads of both crisis and non crisis countries ltros and the lowering of the deposit rate to 0 percent are mainly effective in non crisis countries the smp lowers the spreads of crisis countries but it has the opposite effect on non crisis countries this converse effect is explained by the risk that increasingly accumulates on the ecb s balance sheet through the smp and that way constitutes a fiscal risk for non crisis countries the results are confirmed by pooled ols estimations that measure the effect of unconventional monetary policy on central government debt

price discrimination competition and regulation this paper analyzes some effects of price discrimination policy in a model where a dominant incumbent firm faces an endogenous degree of competition in one of its two markets banning price discrimination tends to encourage more entry which is desirable if the entrant is as efficient as the incumbent but has ambiguous welfare effects more generally prices in both markets might fall price discrimination policy under different forms of price regulation is also examined if the incumbent s average price level is regulated then allowing price discrimination can lead to pricing below marginal cost with possible anticompetitive consequences

turning points in the civil war views from the greenback market in early 1862 the united states government began issuing greenbacks a legal tender currency that was not convertible into gold the government promised to redeem the greenbacks in gold eventually but speculators understood that the probability of redemption depended on union army military fortunes and political developments that affected the total cost of the war to serve the speculative interest in gold a market emerged for the purpose of trading greenbacks for gold dollars because the market price of a greenback reflected the public s perceptions of future war costs the movement of these prices provides unique insights into how people at the time perceived various events we use daily quotations of the gold price of greenbacks to identify a set of dates during the civil war that market participants regarded as turning points in some cases these dates coincide with events familiar from conventional historical accounts of the war in other instances however market participants reacted strongly to events that historians have not viewed as very significant this abstract was borrowed from another version of this item

effectiveness and effects of attempts to regulate the uk petrol industry this paper evaluates the impact that investigation and regulation of the uk petrol industry has had on the profitability of the companies using a gross margin for petrol we estimate a series of variable parameter autoregressive processes the results demonstrate that the 1979 monopolies and mergers commission investigation into the industry caused a long term decline in profit margins in the industry despite the fact that no recommendations or undertakings were made this cannot however be said for subsequent investigations

efficiencies brewed pricing and consolidation in the u s beer industry merger efficiencies provide the primary justification for why mergers of competitors may benefit consumers surprisingly there is little evidence that efficiencies can offset incentives to raise prices following mergers we estimate the effects of increased concentration and efficiencies on pricing by using panel scanner data and geographic variation in how the merger of the brewers miller and coors was expected to increase concentration and reduce costs all else equal the average predicted increase in concentration led to price increases of 2 but at the mean this was offset by a nearly equal and opposite efficiency effect

the dampening of competition effect of exclusive dealing using the dampening of competition approach to understanding vertical relationships this paper shows that in the absence of intrabrand retailer competition firms earn greater profits using exclusive dealing the paper explains the frequent simultaneous appearance of exclusive dealing and exclusive territoriality the results are used to analyze the famous 1949 standard stations case the author concludes that the 1949 court did the right thing for a wrong reason copyright 1990 by blackwell publishing ltd

a treatment effect method for merger analysis with an application to parking prices in paris we propose a method of building control groups for retrospective merger evaluation the procedure involves two parameters a distance or radius and an order of exposure reflecting the notion that a merger can affect an outlet in a more or less direct way we implement the method of estimating the price effect of a merger in the paris parking market and illustrate the consequences of including indirectly exposed outlets in the control group the methodology applies to any industry with spatial competition and allows one to check the sensitivity of the results to the choice of the control group

announcements of ecb unconventional programs implications for the sovereign spreads of stressed euro area countries abstract this paper studies the effects of ecb communications about unconventional monetary policy operations on the sovereign spreads of greece ireland italy portugal and spain relative to germany between 2008 and 2012 more than fifty events concerning non standard operations are identified and classified with respect to the specific ecb program the empirical results suggest that the ecb announcements about unconventional monetary policies substantially reduced long term government bond yield spreads relative to german counterparts in all countries except greece particularly among the different types of measures news about the securities markets programme strongly affected the perceived sovereign risk of the five stressed euro area countries while the announcements of the outright monetary transactions seem to have a significant impact only in italy and spain

quantitative easing and unconventional monetary policy an introduction this article assesses the impact of quantitative easing and other unconventional monetary policies followed by central banks in the wake of the financial crisis that began in 2007 we consider the implications of theoretical models for the effectiveness of asset purchases and look at the evidence from a range of empirical studies we also provide an overview of the contributions of the other articles in this feature

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

the eurozone crisis how banks and sovereigns came to be joined at the hip the eurozone sovereign and banking crisis evolved in three phases following the onset of the subprime tremors in july 2007 the risk premia spreads on bonds issued by eurozone sovereigns rose from historically low levels but they rose largely in tandem across the eurozone membership along with global banking stresses the rescue of the us investment bank bear stearns in march 2008 oddly enough marked the start of a distinctively european banking crisis accompanied by increased differentiation of countries within the eurozone with the greater expectation of public support for distressed banks the spreads that a sovereign paid tended to rise following evidence of stress in its domestic financial sector this was especially so in countries with lower growth prospects and higher debt burdens but there was as yet no feedback from banks to sovereigns finally as the limits of fiscal support for domestic banks became clearer and coinciding with the nationalization of anglo irish in january 2009 but gathering steam with evidence of the greek sovereign s distress in may 2010 sovereign weaknesses also came to be quickly transmitted to a more pessimistic assessment of the financial sector s prospects creating the potential of mutual destabilization ashoka mody and damiano sandri
