asymmetry in retail wholesale and shipping point pricing for fresh vegetables the linkage among retail wholesale and shipping point prices for a select group of fresh vegetables is measured using wolffram s asymmetry model procedures for dealing with discontinuous time series are shown and granger s causality test is used to show the direction of the price linkage wholesale prices are shown to lead both retail and shipping point prices asymmetry in the retail wholesale response indicates that wholesale price decreases are reflected at the retail more so than are wholesale price increases wholesale price decreases are more fully passed through to the shipping point relative to wholesale increases

rockets and feathers understanding asymmetric pricing prices rise like rockets but fall like feathers this stylized fact of most markets is con rmed by many empirical studies in this paper i develop a model with competitive rms and rational partially informed consumers where such asymmetric response to costs by rms emerges naturally in contrast to public opinion and past work collusion is not necessary to explain such result using a rich dataset of retail gasoline prices i nd the observed price dispersion pattern to be consistent with the model s prediction

the monetary approach to exchange rate determination under rational expectations the dollar deutschmark rate abstract this paper reformulates the monetary approach after ascertaining that a money demand function with a partial adjustment mechanism had more empirical support than a money demand function which assumed instantaneous stock adjustment the resulting exchange rate equation is estimated by two rational expectations techniques the parameter estimates are reasonable and are robust to the estimation technique used to different specifications of the driving processes and to changes in the estimation period the structural model outperforms the random walk model and its own unconstrained equivalent a pure time series equation in outof sample forecasts

nonlinear dynamics in deviations from the law of one price a broad based empirical study abstract in this paper we test empirically the validity of the law of one price using data for five major bilateral us dollar exchange rates and nine goods sectors during the recent floating exchange rate regime since the early 1970s using threshold autoregressive models we find strong evidence of nonlinear mean reversion in deviations from the law of one price with plausible convergence speeds consistent with theoretical arguments on international goods markets arbitrage under transactions costs and with an emerging strand of empirical literature these results contribute towards forming a consensus view in favor of discrete regime switching in deviations from the law of one price and the presence of differing nonzero transactions costs across a broad range of goods and countries

transactions costs and vehicle currencies abstract using a simple model of transactions costs in the interbank foreign exchange market and a model of vehicle currency use the interaction between transactions costs and vehicle currency use is explored the impact of volume on bid ask spreads is estimated from cross section time series data on seven currencies data on transactions costs and the currency denomination of trade and capital transactions are used to estimate changes in the attractiveness of using the us dollar as a vehicle between 1980 and 1987 the data suggest a modest reduction in the attractiveness and use of the dollar as a vehicle

search with learning understanding asymmetric price adjustments in many retail markets prices rise faster than they fall we develop a model of search with learning to explain this phenomenon of asymmetric price adjustments by extending our static game analysis to the dynamic setting we demonstrate that asymmetric price adjustments arise naturally when a positive cost shock occurs all the searchers immediately learn the true state the search intensity and hence the prices fully adjust in the next period when a negative cost shock occurs it takes longer for nonsearchers to learn the true state and the search intensity increases gradually leading to slow falling of prices

does money illusion matter reply the data in fehr and tyran ft 2001 and luba petersen and abel winn pw 2013 show that money illusion plays an important role in nominal price adjustment after a fully anticipated negative monetary shock money illusion affects subjects expectations and causes pronounced nominal inertia after a negative shock but much less inertia after a positive shock thus pw provide a misleading interpretation both of our and their own data

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

symmetric pass through of tariffs and exchange rates under imperfect competition an empirical test abstract this paper examines the effect of tariffs and exchange rates on u s prices of japanese cars trucks and motorcycles in particular we test whether the long run pass through of tariffs and exchange rates are identical the symmetry hypothesis we find that this hypothesis is easily accepted in our sample we also find that the pass through relation varies across products ranging from about 0 6 for trucks to unity for motorcycles these coefficients have very different implications for trade policy we explain the results based on demand cost and institutional conditions in each industry

what causes rockets and feathers an experimental investigation prices usually adjust much faster when costs increase than when costs decrease in spite of the many empirical studies confirming this rockets and feathers phenomenon for different industries the mechanism driving it is not well understood we use simple experimental markets with and without search frictions and either privately or publicly observed cost shocks to study how sensitive the rockets and feathers phenomenon is to changes in search costs and information conditions in contrast to standard theoretical predictions we observe price dispersion and spontaneous asymmetric price adjustments in all treatments neither search costs nor private information on cost shocks are indispensable for prices to adjust asymmetrically in the short term the initial asymmetry quickly disappears if the direction of the cost shocks are publicly known while it persists in both treatments with private information

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

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 hangover the lasting impact of early conflict on the duration of bargaining relationships although studies have shown that employer opposition negatively affects the likelihood of success at the certification and first contract stages there is little to no indication of what the long term impact of such opposition might be for relationships that successfully conclude a first agreement using survival analysis on nearly three decades of data from ontario this article investigates whether relationships that experience early conflict encounter a hangover a heightened likelihood of dissolution that extends into the representation phase of the process meaning beyond the settlement of the first agreement using unfair labor practice charges and first contract arbitration applications as proxies for conflict the author finds evidence of a hangover for relationships that exhibit a turbulent start further findings suggest that relationships that experience this early conflict also have a higher likelihood of dissolution throughout the entire relationship

learning in games abstract this essay discusses some recent work on learning in games we explore non equilibrium theories in which equilibrium emerges as the long run outcome of a dynamic process of adjustment or learning we focus on individual level models and more specifically on variants of fictitious play in two player games we discuss both the theoretical properties of the models and their relationship to regularities observed in game theory experiments

retail price cycles and response asymmetry weekly retail gasoline prices in windsor ontario from 1989 to 1994 appear to respond faster to wholesale price increases than to decreases but exhibit a cyclic pattern inconsistent with a common explanation of response asymmetry i reconcile these observations through a model of price cycles prices on the downward portion of the cycle appear insensitive to costs compared with price increases supporting the theory that price decreases result from battles over market share this pattern resembles a faster response to cost increases than to decreases and the conclusion that asymmetry indicates a role for competition policy may be inappropriate jel classification l13 l71 cycles des prix de detail et reponse asymetrique les prix de detail hebdomadaires de la gazoline a windsor ont entre 1989 et 1994 semblent reagir plus vite aux accroissements qu aux chutes des prix de gros mais suivent un pattern cyclique qui ne semble pas consistant avec l explication traditionnelle en termes de reponse asymetrique l auteur reconcilie ces observations a l aide d un modele de cycle de prix les prix dans la portion descendante du cycle semblent insensibles aux variations de couts par comparaison avec les accroissements de prix ce qui supporte la theorie que les chutes de prix resultent de luttes pour les parts de marche le pattern ressemble a celui declenche par une reponse plus rapide aux augmentations qu aux chutes de couts et la conclusion qui voudrait qu on puisse attribuer le tout a l asymetrie des reponses et que donc une intervention de la politique de la concurrence s impose peut etre inappropriee

monetary union a welfare based approach abstract this article attempts to shed light on the consequences of the transition to emu for individual welfare following specific shocks to this end we develop a two country intertemporal general equilibrium model that extends the obstfeld and rogoff journal of political economy 103 3 1995 624 specification to nominal rigidities through price adjustment costs and pricing to market behavior we show that when facing a positive asymmetric permanent shock to either technology or government expenditures occurring in one country implementing a monetary union is beneficial to the households living in this economy conversely it is detrimental to foreigners further a sensitivity analysis shows that if the gains losses to implementing monetary union are qualitatively robust when facing changes in the degree of nominal rigidities and the elasticity of substitution between foreign and domestic goods they are quite sensitive to the degree of pricing to market in the economy

what s different about banks abstract negotiable certificates of deposit cd s trade in the capital market in competition with other securities like commercial paper and bankers acceptances if cd s must pay lenders competitive monetary interest the reserve tax on cd s is borne by bank borrowers viability of the tax means there must be something special about bank loans that makes some borrowers willing to pay higher interest rates than those on other securities of equivalent risk moreover there must be something special about banks that prevents other intermediaries from competing to assure that it never pays to finance loans with cd s

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

purchasing power parity over two centuries abstract this paper re examines the purchasing power parity hypothesis for the dollar sterling exchange rate using the two centuries of data from lothian and taylor lt 1996 real exchange rate behavior the recent float from the perspective of the past two centuries journal of political economy 104 3 488 509 unlike lt we conclude that the dollar sterling rer is nonstationary implying a rejection of the long run ppp hypothesis the differences in our conclusions are explained by 1 sensitivity of adf unit root tests to the choice of lag length and or 2 the presence of significant time trends in the adf or phillips perron unit root test equations

international fish trade and exchange rates an application to the trade with salmon and fishmeal international fish trade is growing and fish exports represent an important source of foreign currency for many countries for a few countries the exports are also an essential part of the economy we revisit the seminal paper of richardson 1978 that addresses the issue of exchange rate pass through in commodity markets but in a multivariate cointegration framework the multivariate cointegration framework allows us to test common assumptions like exchange rate pass through leading price central markets and exogeneity of exchange rates this approach is particularly suited when studying markets for primary products we provide empirical examples using salmon imports to japan and fish meal exports from peru to germany

price dispersion in the lab and on the internet theory and evidence price dispersion is ubiquitous in settings that closely approximate textbook bertrand competition we show that only a little bounded rationality among sellers is needed to rationalize such dispersion a variety of statistical tests based on datasets from two independent laboratory experiments and structural estimates of the parameters of our models suggest that bounded rationality based theories of price dispersion organize the data remarkably well evidence is also presented to suggest that the models are consistent with data from a leading internet price comparison site

risk uncertainty and exchange rates this paper is motivated by two facts failure of log linear empirical exchange rate models of the 1970 s and the observed variability of risk premiums in the forward market rational maximizing models predict that changes in conditional variances of monetary policies government spendings and income growths affect risk premiums and induce conditional volatility of exchange rates i examine theoretically how changes in these exogenous conditional variances affect the level of the current exchange rate and attempt to quantify the extent that this channel explains exchange rate volatility using autoregressive conditional heteroscedastic models

the effects of industry structure on economic exposure abstract a firm is subject to economic exposure if changes in exchange rates affect the firm s value as measured by the present value of its future cash flows this paper shows that in many forms of competition including the most commonly studied case of monopoly the economic exposure of an exporting firm is simply proportional to the firm s net revenues based in foreign currency this simple result breaks down under some but not all forms of competition between the exporting firm and foreign firms in that case the exporting firm needs to know about the price elasticity of its product demand and its marginal cost in order to assess its exposure to exchange rates the key determinant of economic exposure therefore is the competitive structure of the industry in which a firm operates

the failure to negotiate first contracts determinants and policy implications this study examines why unions after winning certification rights fail to secure agreements in roughly one of every four first contract negotiations hypotheses are derived from chamberlain s theory that the relative power of the negotiating parties is a function of the costs of agreeing and disagreeing costs that are shaped by economic legal and organizational factors the author analyzes data through 1982 on 118 cases in which unions had won nlrb elections in indiana in the years 1979 and 1980 he finds that an employer s discrimination against union activists and his refusal to bargain measured by section 8 a 3 and 8 a 5 charges deemed meritorious by the regional office of the nlrb have substantial negative effects on the probability that a first contract will be reached similarly negative efffects result from lengthy delay in the nlrb s resolution of employer objections and challenges to lost elections on the other hand unions are also more likely to obtain first contracts when firms pa

logit estimates of strike incidence from canadian contract data logit estimates of strike incidence are made based on a unique and comprehensive data set of 2 437 collective agreements the appropriate level of aggregation since that is where bargaining occurs the results are interpreted through a theoretical framework emphasizing that strikes are more likely when the joint costs of using the strike mechanism are low relative to the cost of alternative mechanisms for achieving the same purposes such functions of strikes are to generate information elicit truth telling establish reputations provide catharsis and solve intraorganizational conflict

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

economic impacts of new unionization on private sector employers 1984 2001 economic impacts of unionization on employers are difficult to estimate in the absence of large representative data on establishments with union status information estimates are also confounded by selection bias because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages using multiple establishment level data sets that represent establishments that faced organizing drives in the united states during 1984 1999 this paper uses a regression discontinuity design to estimate the impact of unionization on business survival employment output productivity and wages essentially outcomes for employers where unions barely won the election e g by one vote are compared with those where the unions barely lost the analysis finds small impacts on all outcomes that we examine estimates for wages are close to zero the evidence suggests that at least in recent decades the legal mandate that requires the employer to bargain with a certified union has had little economic impact on employers because unions have been somewhat unsuccessful at securing significant wage gains

tailwinds from the east how has the rising share of imports from emerging markets affected import prices this paper quantifies the effect of the rising share of imports from emerging market economies emes on import price inflation in the uk using a panel regression approach that accounts for heterogeneity across industries we estimate that between 1999 and 2011 the rise in china s import share of manufactured goods lowered uk import price inflation by around 0 5 percentage points per year we call this the tailwind rising imports from other eme country groups are not found to have any significant impact our approach allows us to decompose this effect two thirds arises from the direct impact of switching to lower cost chinese goods the remaining third comes from other exporters lowering their prices in response to stronger competition from china we find no evidence that higher inflation rates in emes has so far reduced or reversed the sign of this tailwind

when do consumers search this paper provides empirical evidence relating search to price movements we measure consumer search directly from traffic statistics for web sites that report gasoline prices we show empirically that consumers search more as prices rise than they do when prices fall asymmetric search patterns have consequences for price behavior our findings indicate that retail margins are squeezed by increased search in addition we show that there is more price dispersion when prices are falling than when prices are either stable or rising our results provide a search based explanation for the rockets and feathers phenomenon of asymmetric price adjustment

pass through of exchange rates and purchasing power parity abstract in this paper we develop and test two hypotheses about purchasing power parity ppp the first is that changes in the price of traded goods relative to domestic substitutes will affect the ppp relation due to the partial pass through of exchange rates the second is that ppp should hold on forward rather than spot exchange rates due to hedging by firms which implies that the interest rate differential should enter the ppp relation for spot rates using quarterly data for several countries we find support for both these hypotheses though the magnitude of the interest rate effect is very small

pricing to market in european automobile exports to oecd countries a panel data approach this paper investigates pricing to market behaviour using data for european auto exports the empirical analysis uses forward instead of spot exchange rates cross country and cross product analyses reveal that pricing behaviour depends mainly on the class of product while the country of origin and destination appears as less important furthermore the data do not usually reject the hypothesis of a symmetric response of export prices to depreciations and appreciations of the exporter s currency finally although the point estimates confirm the combined influence of the business cycle and the direction of the exchange rate movements on pricing to market in most cases formal tests seldom provide statistical significance for this result

the deposits channel of monetary policy we propose and test a new channel for the transmission of monetary policy we show that when the fed funds rate increases banks widen the interest spreads they charge on deposits and deposits ow out of the banking system we present a model in which imperfect competition among banks gives rise to these relationships an increase in the nominal interest rate increases banks market power inducing them to increase deposit spreads and hence restrict deposit supply households respond to the increase in deposit prices by substituting from deposits into less liquid but higheryielding assets consequently changes in the nominal interest rate aect banks cost of capital and lending using branch level data on the universe of u s banks we show that following an increase in the fed funds rate deposit spreads increase by more and supply falls more in areas with less deposit competition we control for changes in banks lending opportunities by comparing branches of the same bank we control for changes in macroeconomic conditions by showing that deposit spreads widen immediately after a rate change and even if this change is fully anticipated our results imply that monetary policy has a signicant impact on how the nancial system is funded on the quantity of safe and liquid assets it produces and on its provision of loans to the real economy

cointegration tests of purchasing power parity the case of swiss exchange rates abstract this paper tests purchasing power parity ppp as a long run equilibrium condition by examining the long run relationshiop between exchange rates and wholesale price indices using cointegration tests this paper avoids some of the problems of previous cointegration tests of ppp by using more precise data pretests and by not imposing a priori restrictions upon the cointegrating vector of the nine combinations of swiss exchange rates and price indices examined cointegration is detected in seven cases thus supporting ppp as a long run equilibrium jel f31 c32

business as usual a consumer search theory of sticky prices and asymmetric price adjustment abstract empirical evidence suggests that prices are sticky with respect to cost changes moreover prices respond more rapidly to cost increases than to cost decreases we develop a search theoretic model which is consistent with this evidence and allows for additional testable predictions our results are based on the assumption that buyers do not observe the sellers costs but know that cost changes are positively correlated across sellers in equilibrium a change in price is likely to induce consumer search which explains sticky prices moreover the signal conveyed by a price decrease is different from the signal conveyed by a price increase which explains asymmetry in price adjustment

exchange rates and traded goods prices abstract this paper presents a partial equilibrium model of the determination of domestic and export prices by a monopolistic competitive firm the model stresses the role of exchange rate uncertainty and expectations the most important result of the analysis is that the stochastic properties of deviations from the law of one price are crucially affected by the currency of denomination of export prices using data on domestic and dollar export prices of japanese goods i find that deviations from the law of one price are due to exchange rate surprises but also to price staggering and ex ante price discrimination

fairly priced deposit insurance and bank charter policy the thrust of current deposit insurance reform risk based insurance premiums and capital requirements is an effort to price deposit insurance more fairly fairly pricing deposit insurance eliminates inequitable wealth transfers but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy results in an efflcient separating equilibrium this article analyzes the effect of alternative charter policies when deposit insurance is fairly priced the thrust of current deposit insurance reformrisk based capital requirements 1988 and risk based insurance premiums 1994 is an effort to price deposit insurance more fairly chan greenbaum and thakor s 1992 seminal paper dramatically illustrated that fairly pricing deposit insurance is not enough to solve the deposit insurance problem in their model when banks hold nontraded private information assets no equilibrium exists with fairly priced deposit insurance unless banks earn rent or are subsidized fairly pricing deposit insurance eliminates inequitable transfers of wealth but it does not lead to an efficient equilibrium this paper shows that an alternative charter policy gives an efficient separating equilibrium the separating equilibrium segregates the market for insured transactions deposits from private information financial intermediation the analysis in this article provides support for the deposit insurance reform proposal in the recent 1993 national commission on financial institution reform recovery and enforcement ncfirre report to the president and congress and for merton and bodie s 1993 proposal both proposals impose a separating equilibrium that isolates insured transactions accounts and the public information traded assets that secure them from private information assets in the bank s portfolio the formal model developed here is designed to demonstrate the effect of charter policy on the efficiency of market equilibrium in an uncomplicated setting but the main result that a separating equilibrium is more efficient is extremely robust with respect to the model specification the model has two types of financial intermediaries intermediaries that hold nontraded private

long run purchasing power parity during the recent float abstract this paper examines the relevance of long run purchasing power parity ppp which allows for measurement errors during the recent floating exchange rate period previous empirical studies generally fail to find support for long run ppp over this period in this paper in this paper the cointegration property of exchange rates and prices is examined using maximum likelihood procedure and we find significant evidence favorable to long run ppp further tests for symmetry and proportionality indicate that these two conditions are not generally with the data the results support the hypothesis of long run ppp with measurement errors in prices

contraction and expansion the divergence of private sector and public sector unionism in the united states the institutional structure of the american labor market changed remarkably from the 1950s and 1960s to the 1980s in the 50s and 60s trade unions seemed permanently established in the private sector of the economy a third of nonagricultur al wage and salary workers and over half of blue collar workers were union members hundreds of thousands of workers voted annually in national labor relations board nlrb representation elections to join unions most large firms sought stable collective bargaining relations with their unions by contrast in the public sector only 10 12 percent of workers were union members fewer were covered by collective bargaining contracts and most experts regarded public employees as intrinsically nonorganizable according to afl cio president george meany it was impossible to bargain collectively with the government kramer 1962 p 14 the massive contraction of unionism in the private sector and expansion in the public sector in the 1970s and 1980s see exhibit 1 has produced an utterly different situation today in the private sector the proportion of wage and salary workers in unions plummeted to 14 percent in 1986 a level comparable to that in the great depression only a minuscule number of workers joined unions through nlrb elections and national companies openly proclaimed their intent to establish a union free environment by contrast in the public sector over a third of the work force was unionized some 40 percent were covered by collective contracts 1 and 1 estimates of organization in the public sector differ somewhat among sources though all data show greater organization than in the private sector see freeman ichniowski and zax forthcoming for a detailed analysis of the various statistics

competition and pricing in the credit card market many credit card issuers charge fixed rates that remain the same for three to five years while the rest charge variable rates that are indexed to market rates the presence of these two distinct rate types forces prices at firms selling an otherwise identical product to move asynchronously variable rates move one for one with the index while fixed rates stay constant empirical and theoretical analysis shows that this pricing structure provides an explanation for the simultaneous yet seemingly contradictory existence of high rate cost margins and aggressive non price competition for new customers a phenomenon that existed in the credit card market in the early 1990s

the rigidity of prices this paper uses evidence on individual transaction prices to analyze price behavior the evidence shows that for many transactions pricesremain rigid for periods exceeding one year the rigidity of price ispositively correlated with industry concentration for several productsthe correlation of price changes across buyers is low the paper alsoinvestigates the relationship between price rigidity price change andthe length of time a buyer and seller have been doing business together the author interprets the evidence as emphasizing the importance of nonprice rationing and the inadequacy of models in whichprice movements alone clear markets copyright 1986 by american economic association

optimum pricing policy under stochastic inflation we describe aggregate inflation as a stochastic process in which the rate of change of the price level can be positive or zero where the times spent in each state are of random duration this class of processes includes two state markov chains and renewal processes as special cases it is shown that the optimal pricing policy of a monopolistic firm with non convex costs of price adjustment is s s in its real price i e its nominal price relative to the price level a basic certainty equivalence result is proved i e the firm behaves as if it faces a certain and fixed rate of inflation higher than the actual expected rate the difference between the two rates being a risk premium which depends on the real interest rate and the parameters of the stochastic process one can thus apply previous results from the case of certainty sheshinski and weiss review of economic studies 1977 to obtain comparative static results in particular one finds that an increase in the variance of expected inflation leads firms to choose a pricing policy with larger amplitude in real price the paper also addresses the question of consistency in firms expectations when the price level is determined by the firms actions in this paper we consider pricing policies of individual firms in an inflationary environment each firm expects the general price level to increase and must determine the rate of increase of its own price it is assumed that the firm incurs an adjustment cost when it changes its nominal price consequently firms choose to change prices occasionally rather than continuously

learning from inferred foregone payoffs abstract a player s knowledge of her own actions and the corresponding payoffs may enable her to infer or form beliefs about what the payoffs would have been if she had played differently for quantitative learning models employed in studies of low information environments players ex post inferences and beliefs have been largely ignored for games with large strategy spaces this omission can seriously weaken the predictive power of a learning model we propose a novel method of using players ex post inferences and assessments to impute foregone payoffs for unplayed strategies in low information environments we then use the resulting learning model to explain the pricing and learning behavior observed in a bertrand market experiment maximum likelihood estimation shows that the extended model organizes the data remarkably well at both the aggregate and individual levels

multimarket contact competition and pricing in banking abstract in this paper we assess the impact of multimarket contact of banks on their market power by means of a simultaneous equation model in which the divergence of price from marginal cost is a function of multimarket linkages the model is estimated using aggregate data from the italian regions for the years 1997 2009 our results show that multimarket contact is positively and significantly correlated to the market power index and is also connected to both home and non home market concentration the evidence is robust to changes in model specification and multimarket contact measures and supports the idea that firms which have a greater amount of contact are more likely to collude

in which currency should exporters set their prices this paper studies the choice of price setting currency for an exporter faced with the choice of setting price in his own in the importers or a third currency under exchange rate uncertainty we establish that sufficient conditions on demand and cost functions for exchange rate pass through to be less than unity under certainty are also sufficient conditions for price setting in the importer s currency to yield the highest expected profit under exchange rate uncertainty under the same conditions on demand and cost functions setting price in the importer s currency maximizes expected utility when risk aversion and forward currency markets are introduced

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

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

the effect of labour relations legislation on strike incidence the impact on strike incidence of nine labour relations policy variables representing legislation in eleven canadian jurisdictions is estimated using logit analysis of 3 347 individual collective agreements mandatory strike votes compulsory dues check off and compulsory conciliation boards are associated with significantly lower strike probabilities prohibition of replacement workers and employer initiated strike votes are associated with significantly higher strike probabilities no significant association was found between strike incidence and the length of cooling off period following conciliation and negotiated or automatic reopeners policy impacts are interpreted in a framework emphasizing the influence of asymmetric inforrnation and joint costs on strikes

determinants of the outcomes of union certification elections this study analyzes determinants of union election outcomes at the level of the work unit within a theoretical framework of utility maximization voting behavior is modeled as a function of the social psychology of groups the economic and sociopolitical environment nlrb procedures and the extent of union organization of the industry utilizing nlrb certification election records for 1979 the author finds a negative relationship between unit size and union victories in units of fewer than 65 workers but no relationship in larger units also negatively related to union victories are delays between petition and election dates elections held in southern states having right to work laws and elections involving the teamsters in contrast workers are more likely to vote for representation as unemployment levels and the proportion of consent elections rise and as the rate of unionization in their industry rises to 35 percent

the eyes of the needles a sequential model of union organizing drives 1999 2004 this paper models three stages of the union organizing drive using a new dataset covering more than 22 000 drives that took place between 1999 and 2004 the correlated sequential model tracks drives through all of their potential stages holding an election winning an election and reaching first contracts only one seventh of organizing drives that filed an election petition with the nlrb managed to reach a first contract within a year of certification the model which controls for the endogeneity of unfair labor practice ulp charges finds that a ulp charge was associated with a 0 smaller cumulative chance of reaching such a contract ulp charges had less effect on the votes cast than on the decision to hold an election and the ability to reach a first contract a sequential model such as this one could be extended to test between some competing theories about the determinants of union organizing

equivalence results for optimal pass through optimal indexing to exchange rates and optimal choice of currency for export pricing firms sometimes write price lists or catalogs for their exports so they set prices for a period of time and do not adjust prices during that interval in response to changes in their environment the firm sets the price either in its own currency or the importer s currency this paper draws a simple link between the choice of currency and the pricing decision of a firm that changes prices in response to all shocks specifically if the latter firm s price has a lower variance in terms of its own currency than the importer s currency then the firm with a price list will set the price in its own currency and otherwise it will set price in the foreign currency this relationship is established by consideration of the firm with a price list as a special case of a firm that indexes its export price to the exchange rate jel f4 f1

discriminating monopoly forward markets and international trade recent empirical studies see e g kravis and lipsev 1977 1978 isard 1977 aspe and giavazi 1982 demonstrate that there are notable divergencies between domestic and export prices this empirical evidence suggests that the law of one price is systematically violated kravis and lipsey 1977 p 155 argue that many firms involved in international trade particularly manufacturers are in the position of a discriminating monopolist faced with separate markets each characterized by a different demand elasticity a model which explicitly allows for price discrimination has been used by several authors see for example aspe and giavazi 1982 ethier 1982 katz paroush and kahana 1982 and tarr 1979 katz paroush and kahana 1982 hereafter kpk used a model of a price discriminating firm which operates under price uncertainty to investigate its optimal level of output and sales in the two markets the main assumption made in kpk 1982 is that the firm determines its level of output and the allocation of sales between the two markets before the resolution of uncertainty furthermore no forward markets were available to this firm in this paper we analyze a price discriminating firm which sells its produce both in the domestic and on world markets under either exchange rate uncertainty or foreign price uncertainty this firm is a monopoly in the domestic market but a price taker on the world market our model differs substantially from the kpk model and in some cases conforms better with reality due to the following two assumptions first the firm determines its level of output before the resolution of uncertainty but decides about the optimal allocation of sales only after it observes the foreign price denominated in domestic currency secondly forward markets to share the exchange rate risk or the uncertain foreign commodity price are available and their impact on the firm s policy is analyzed hence this work integrates two strands of literature it combines studies on price discriminating firms some were mentioned above and studies on firm behavior when forward markets are available danthine 1978 holthausen 1979 katz and paroush 1979 feder just and schmitz 1980 in this paper we are mainly concerned with a firm which always exports this includes large

the price concentration relationship in banking the commonly observed positive correlation between market concentration and profitability may be explained by noncompetitive pricing behavior as argued by the structure performance hypothesis or by the greater efficiency of firms with dominant market shares as argued by the efficient structure hypothesis by examining the price concentration relationship instead of the profit concentration relationship this paper tests the structure performance hypothesis in a manner that excludes the efficient structure hypothesis as an alternative explanation of the results the results strongly support the structure performance hypothesis and are robust with respect to model specification measurement of concentration and econometric technique copyright 1989 by mit press

the effects of public policy on strike duration hazard function estimates are utilized to analyze the effect of numerous public policy variables on strike duration based on 7 546 strikes in canada between 1967 and 1985 we find that only the mandatory strike vote substantially reduced conditional duration however the policy variables generally had a more favorable effect on reducing strike incidence so that on net they tended to reduce unconditional duration incidence times conditional duration specifically reduced unconditional duration was associated with the existence of conciliation and the requirement of a mandatory strike vote but the prohibition on replacement workers had a perverse effect

international comparisons of pricing to market behavior this paper measures the degree of price discrimination across export destinations that is associated with exchange rate changes using u s u k german and japanese industry level data given the industries sampled more price discrimination across destinations is observed in the u k german and japanese data for industries that match across source countries however behavior is very similar across source countries furthermore destination specific price adjustment on exports to the united states from germany and japan is similar to price adjustment observed on shipments to other destinations most variation in the data appears to be related to industry copyright 1993 by american economic association
