adjustment costs and pricing to market theory and evidence abstract this paper develops an adjustment cost model of pricing to market the model consists of a monopolist who supplies an identical nondurable good to two foreign markets it is shown that the degree of pricing to market increases with the relative importance of the transitory component in exchange rates customs data from 1978 through 1987 on u s and canadian imports of seven german commodities are used to estimate the model s parameters and test its over identifying restrictions

price regulation and parallel imports of pharmaceuticals abstract this paper studies the effects of price regulation and parallel imports in the on patent pharmaceutical market in a theory model where the producer price is subject to bargaining between the brand name producer and a distributor we show that the effects of stricter price regulation crucially depend on whether the producer faces competition from parallel imports while parallel imports improve the bargaining position of the distributor price regulation counteracts this effect and may even be profitable for the producer we test the implications of our model on a unique dataset with information on sales and prices at both producer and retail level for 165 substances over 4 years 2004 2007 we show that stricter price regulation reduces competition from parallel imports and has no strictly negative effect on producer profits in the presence absence of parallel imports our results suggest that price regulation might improve static efficiency without being harmful for dynamic efficiency in the presence of parallel imports

pareto price discrimination abstract as the collection of consumer data becomes more common online merchants are better equipped to price discriminate now more than ever before while standard first degree price discrimination benefits merchants and harms consumers relative to uniform pricing i derive an alternative first degree pricing strategy that achieves efficiency and pareto improves upon the uniform pricing equilibrium furthermore i show that price ceilings can enforce these pareto price discrimination strategies making pareto price discrimination a viable option for merchants and policy makers

the evolution of price dispersion in the european car market car prices in europe are characterized by large and persistent differences across countries the purpose of this paper is to document and explain this price dispersion using a panel data set extending from 1980 to 1993 we first demonstrate two main facts concerning car prices in europe i the existence of significant differences in quality adjusted prices across countries with italy and the u k systematically representing the most expensive markets 2 substantial year to year volatility that is to a large extent accounted for by exchange rate fluctuations and the incomplete response of local currency prices to these fluctuations these facts are analysed within the framework of a multiproduct oligopoly model with product differentiation the model identifies three potential sources for the international price differences price elasticities generating differences in markups costs and import quota constraints local currency price stability can be attributed either to the presence of a local component in marginal costs or to markup adjustment that is correlated with exchange rate volatility the latter requires that the perceived elasticity of demand is increasing in price we find that the primary reason for the higher prices in italy is the existence of a strong bias for domestic brancs that generates high markups for the domestic firm fiat in the u k higher prices are mainly attributed to better equipped cars and or differences in the dealer discount practices the import quota constraints are found to have a significant impact on japanese car prices in italy france and the u k with respect to local currency price stability a large percentage of the documented price inertia can be attributed to local costs and a smaller fraction to markup adjustment that is indicative of price discrimination based on these results we conjecture that the emu will substantially reduce the year to year volatility observed in the car price data but without further measures to increase european integration it will not completely eliminate existing cross country price differences

parallel imports demand dispersion and international price discrimination parallel imports goods imported by unauthorized resellers are advocated worldwide for undermining international price discrimination for a continuum of markets we find that uniform pricing by a monopolist yields lower global welfare than third degree discrimination if demand dispersion across markets is large though uniform pricing avoids output misallocation too many markets go unserved mixed systems permitting discrimination across but not within designated groups of markets yield significantly higher welfare than uniform pricing or unrestricted multimarket discrimination and can pareto dominate uniform pricing thus while parallel imports might benefit some countries our results weaken the multilateral case for allowing them

the effects of third degree price discrimination in oligopoly retail firms and restaurants commonly offer senior citizen discounts i suspect this practice is not motivated by altruism rather the behavior can be better explained as profit maximizing price discrimination these firms are setting a low price in a market which probably has high elasticity of demand but why should the demand of senior citizens be more elastic than average one possibility is that elderly people have below average income and they would not eat out if restaurant prices were high perhaps a more plausible explanation is that retired people simply have more time on their hands to spend commuting across town to take advantage of discounts the purpose of these discounts may then be to lure senior citizens away from other restaurants rather than to get them out of the house the analysis of third degree price discrimination has a long history a c pigou 1920 joan robinson 1933 and two articles on the subject have recently appeared in this review richard schmalensee 1981 hal varian 1985 the industry structure in these analyses is monopoly but an explicit model of some form of competition is obviously needed to study discriminatory discounts meant to attract customers from rival firms and even discounts meant to get people out of the house may have an oligopoly analysis which is qualitatively different from their monopoly anlysis in this paper i present a simple duopoly model of a differentiated products industry i show that a firm s price elasticity of demand in a market can be expressed as the sum of two parts the industry demand elasticity and the cross price elasticity the first measures the tendency of consumers in a market to stay home when the price goes up the second the tendency to switch suppliers in the monopoly case in which the crossprice elasticity is zero and the collusive case in which the cross price elasticity is irrelevant discrimination between markets is due to differences in industry demand elasticity in the noncooperative oligopoly case equilibrium price differentials can be accounted for both by differences in cross price elasticity as well as differences in industry demand elasticity total industry output when the firms can discriminate between two markets is compared to what it would be if discrimination were impossible which regime has larger output depends on the sum of the adjustedconcavity condition and the elasticity ratio condition the first predominates when the rival products are poor substitutes and the firms have approximate monopoly power while the second predominates at the other extreme where the products are close substitutes and the firms have almost no market power the adjusted concavity condition compares the relative curvature of demands in the two markets and was originally discovered by robinson 1933 in her analysis of monopoly price discrimination the elasticity ratio condition compares the relative difference in industry demand elasticity between the two markets with the relative difference in cross price elasticity according to the elasticity ratio condition a discriminatory discount due to high industry elasticity of demand would be more likely to increase total output than one due to high cross price elasticity the effect of discrimination on profit is also discussed the distinction made here department of economics university of wisconsin madison madison wi 53706 this paper is a revision of part of my doctoral dissertation i am grateful to steve matthews ken judd and john panzar for guidance in this research i also thank seminar participants at wisconsin the justice department and the 1986 econometric society meetings in new orleans and the discussant martin perry the excellent comments of the referees improved the exposition of the paper

price discrimination and patent policy patent and antitrust policy are often presumed to be in conflict as an important example there is ongoing controversy about whether price discrimination by a patent holder is an illegal or socially undesirable exploitation of monopoly power in this article we show that no conflict exists in many price discrimination cases even ignoring the dynamic effects on incentives for innovation third degree price discrimination by patent holders can raise static social welfare in fact pareto improvements may well occur welfare gains occur because price discrimination allows patent holders to open new markets and to achieve economies of scale or learning further even in cases where discrimination incurs static welfare losses it may be efficient relative to other mechanisms such as length of patent life for rewarding innovators with profits

the tragedy of the grabbed commons coercion and dispossession in the global land rush rural populations around the world rely on small scale farming and other uses of land and natural resources which are often governed by customary traditional and indigenous systems of common property in recent years large scale land acquisitions have drastically expanded it is unclear whether the commons are a preferential target of these acquisitions here we argue that the contemporary global land rush could be happening at the expense of common property systems around the world while there is evidence that common property systems have developed traditional institutions of resource governance that make them robust with respect to endogenous forces e g uses by community members it is less clear how vulnerable these arrangements are to exogenous drivers of globalization and expansion of transnational land investments in common property systems farmers and local users may be unable to defend their customary rights and successfully compete with external actors we define the notion of commons grabbing and report on an exploratory study that applied meta analytical methods drawing from the recent literature on large scale land acquisitions and land grabbing informed by political economy and political ecology approaches we coded selected cases on the basis of acquisition mechanisms claims and property rights changes in production system and coercive dynamics and explored the interactions between the different variables using association tests and qualitative comparative analysis we found that the majority of the cases included in this analysis 44 of 56 could be examples of commons grabbing

international price discrimination the pharmaceutical industry abstract it is generally asserted that price discrimination is a common feature of the international pharmaceutical market resulting in unnecessarily high medical costs to developing countries since it is pharmaceuticals that are the largest component of their health care expenditures however little comprehensive empirical research has been carried out to test this hypothesis this article compares the prices of identical packages of pharmaceutical products for 32 countries for the year 1975 and examines which factors contribute to thehuge price differences a strong positive relationship between price level and per capita gdp is found a 10 increase in per capita income being associated with on average 8 higher drug prices the implementation of direct price control measures by the government results on average in a 20 price reduction while government policies such as bulk purchasing through a centralized government agency promotion of the use of generics and to a lesser extent excluding patent protection seem to be sucessful in lowering the general price level of pharmaceuticals these results suggest that the pharmaceutical industry charges what the market will bear

the impact of parallel imports on investments in cost reducing research and development abstract we develop a two country model of endogenous investment in process innovation by a manufacturer facing competition from parallel imports pi we find that the distortions associated with pi inhibit innovation however the difference between the manufacturer s expected profits under successful and failed innovation is u shaped in the cost of engaging in pi thus the reduction in r d investment depends on both legality of pi and transport costs the reduction in innovation could harm global welfare depending on whether the manufacturer was deterring pi with a high wholesale price if so banning such trade would raise expected welfare

international effects of national regulations external reference pricing and price controls under external reference pricing erp the price that a government permits a firm to charge in its market depends upon the firm s prices in other countries in a two country home and foreign model where demand is asymmetric across countries we show that home s unilaterally optimal erp policy permits the home firm to engage in a threshold level of international price discrimination above which it is just willing to export if the firm faces a price control abroad or bargains over price with the foreign government an erp policy can even yield higher home welfare than a direct price control

parallel imports and repair services abstract this study explores the welfare effects of parallel imports when the producer may refuse to provide repair services for parallel imported units which reduces the degree of price convergence between countries if the probability of the product s breakdown is endogenously determined by the producer permitting parallel imports could increase the probability because a higher probability leads to a larger price gap as a result it is possible that prices increase and welfare deteriorates in both countries this negative welfare effect is more likely to emerge as the liberalization of trade in goods proceeds the prohibition of service discrimination recovers the positive welfare effect

effects of transitory consumption and temporal aggregation on the permanent income hypothesis this paper shows that u s monthly consumption data are consistent with the permanent income hypothesis when transitory consumption and temporal aggregation effects are jointly incorporated into the model in this case a more appropriate representation for the permanent income hypothesis is the integrated moving average ima 1 1 process with a negative ma coefficient rather than the repeatedly rejected random walk process restrictions on the relative importance of transitory and permanent consumption are also discussed with and without measurement errors copyright 1993 by mit press

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

exchange rate pass through when market share matters the authors investigate the pass through from exchange rates to import prices when firms future demands depend on their current market shares they show that profit maximizing foreign firms may either raise or lower their dollar export prices when the dollar appreciates temporarily i e the pass through may be perverse and that current import prices may be more sensitive to expected future exchange rates than to current exchange rates they present evidence that suggests the behavior of expected future exchange rates may provide a clue to the puzzling recent behavior of u s import prices copyright 1989 by american economic association

exchange rates and prices the adjustment of relative prices to exchange rate movements is explained in an industrial organization approach given labor costs in the respective currencies exchange rate movements change costs for firms selling in the home market and thus disturb the industry equilibrium the extent of absolute and relative price adjustment is shown to depend on market integration product substitutability the relative number of domestic and foreign firms and the market structure the impact of exchange rates on prices is illustrated in a variety of approaches including the cournot a dixit and j stiglitz 1977 and s salop 1979 models some empirical evidence is offered in support of the theory copyright 1987 by american economic association

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
