explaining the border effect the role of exchange rate variability shipping costs and geography this paper exploits a three dimensional panel data set of prices on 27 traded goods over 88 quarters across 96 cities in the us and japan we show that a simple average of good level real exchange rates tracks the nominal exchange rate well suggesting strong evidence of sticky prices focusing on dispersion in prices between city pairs we find that crossing the us japan border is equivalent to adding as much as 43 000 trillion miles to the cross country volatility of relative prices we turn next to economic explanations for this so called border effect and to its dynamics distance unit shipping costs and exchange rate variability collectively explain a substantial portion of the observed international market segmentation relative wage variability on the other hand has little independent impact on segmentation 2001 elsevier science b v all rights reserved

institutional determinants of labor reallocation in transition the transition process differed in the countries of the former soviet union fsu and those of central and eastern europe cee in terms of reallocation of labor real wage employment and output adjustment we sift through the theoretical and empirical literature to find an explanation for these diverging adjustment trajectories and conclude that they can be explained by the fact that the cee countries adopted social policies that upheld wages at the bottom of the distribution forcing the old sector to restructure or collapse while the fsu countries allowed wages to free fall not forcing the hand of the old sector

real exchange rates and relative prices an empirical investigation abstract this paper uncovers a striking empirical regularity the consumer price of a good relative to a different good within a country tends to be much less variable than the price of that good relative to a similar good in another country this fact seems to hold for all goods except very simple homogeneous products models of real exchange rates are likely to have predictions regarding this relation so this fact may provide a useful gauge for discriminating among models

the use and impact of business advice by smes in britain an empirical assessment using logit and ordered logit models this study assesses the effect of differences in types of client on the use and impact of business advice by smes in britain using new survey evidence from the cambridge esrc centre for business research survey of 1997 the survey covering over 2500 respondents is the largest and most definitive assessment available in britain moreover the survey allows an assessment of the full range of providers of external advice the private sector business associations and various public sector bodies as well as the fields of advice using multivariate logit models it is found that size of firm rate of growth and innovation appear to be the main variables influencing the likelihood of firms seeking external advice both from different sources and from different fields other variables which are investigated include age profitability skill levels manufacturer services and exporter nonexporter ordered logit models of the impact of the advice demonstrate that there are significant differences between client

durable goods monopolists durable goods monopolists face special problems because the sale of their products creates a secondhand market not controlled by the monopolist to the extent the monopolist is able to rent his product rather than sell it or to make binding promises about his future production such problems are ameliorated given the inability to do the above the monopolist is led to producing goods less durable than those produced by either competitive firms or monopolist returns a reverse averch johnson result that monopolist sellers may invest less in fixed costs including plant modernization and research and development than would the renters is shown it is also shown that even though sellers have less monopoly power than renters and nondurable goods monopolists it is possible that the seller will cause a greater deadweight loss than the other types of monopolies

does information undermine brand information intermediary use and preference for branded web retailers abstract investments in advertising to create brands provide one method for vendors to convince potential customers that vendors will deliver as promised alternatively third party information on whether retailers tend to keep their commitments can serve a similar function and may undermine investments in brand this study uses a 13 month panel dataset on 1998 99 internet shopping behavior and use of information intermediaries by over 30 000 households to examine whether information use undermines brand we find that individuals using price comparison sites such as dealtime and mysimon reduce their amazon shopping by about a tenth while individuals using bizrate which provides both price comparison and vendor reliability information reduce their amazon shopping by a quarter the results have possible implications for both firm strategy and the evolution of market structure if information weakens the pull of brand then internet retailing may grow less concentrated over time we are grateful to the wharton e business initiative webi for financial support

prices and price dispersion on the web evidence from the online book industry using data collected between august 1999 and january 2000 covering 399 books we examine pricing by thirty two online united states based bookstores at the aggregate level we find that both advertising and competitive structure had the predicted effects more competition led to lower prices and to lower price dispersion holding competitive structure constant more widely advertised items also had lower prices at the firm level we observe considerable heterogeneity in behavior firms had differentiated or attempted to differentiate on dimensions such as brand price and selection

sme growth the relationship with business advice and external collaboration the paper presents multivariate analysis of the relationship of sme growth with the acquisition of external business advice whilst controlling for the influence of sme characteristics of age manufacturing services high technology innovator level of skill of the workforce exporter and number of competitors the relationship of external business advice with sme performance is statistically significant for only a small number of sources and fields obtaining external advice in fields such as business strategy and staff recruitment is associated with positive firm performance the main positive relationships of advice and performance are dominated by private sector sources such as lawyers suppliers customers and business friends relatives collaborative arrangements with suppliers nationally internationally have a strong positive relationship with employment and turnover growth collaboration with local suppliers has a strong positive relationship with growth in profitability there is little evidence of statistically significant relationships between government backed providers of business advice such as business link and firm performance

retail strategies on the web price and non price competition in the online book industry two conflicting predictions have emerged regarding the effect of low cost information on price the first states that all internet retailers will charge the same low price for mass produced goods the second states that internet retailers will differentiate to avoid intense price competition using data collected in april 1999 on the prices of 107 books in thirteen online and two physical bookstores we find similar average prices online and in physical stores and substantial price dispersion online analysis of product differentiation yields no clear results the substantial premium charged by amazon provides indirect evidence of product differentiation

unemployment dynamics and the restructuring of the slovak unemployment benefit system abstract this paper is about the effects on unemployment dynamics of the restructuring of the slovak system of unemployment benefits using data collected by the public employment offices we investigate the effects of the strengthening of the system which occurred january 1 1992 and the loosening of the system for some age groups introduced january 1 1995 we find evidence that the strengthening of the system reduced unemployment duration whereas the loosening increased unemployment duration however none of the changes did significantly affect the flow from unemployment to regular jobs

price dispersion and loss leader pricing evidence from the online book industry in this paper we develop a theoretical model to analyze the pricing strategies of competing retailers with asymmetric cross selling capabilities when product demand changes our results suggest that retailers with better opportunities for cross selling have higher incentives to adopt loss leader pricing on high demand products than retailers with low cross selling capabilities as a result price dispersion of a product across retailers rises when its demand increases the predictions of our model are consistent with the empirical evidence from the online book retailing industry using product breadth as a proxy for cross selling capability we find that retailers with high cross selling capabilities reduce prices on best sellers more aggressively than retailers with low cross selling capabilities as a result price dispersion increases when a book makes it to the best seller list and the increase is mainly driven by the difference in pricing behavior between retailers with different cross selling capabilities our empirical results are robust against a number of alternative explanations

search and collusion in electronic markets we examine the impact of reduced search costs on prices of commodity products in electronic marketplaces conventionally reduced consumer search costs may be expected to engender stronger price competition between firms resulting in lower prices and improved consumer welfare this notion was formalized in stahl 1989 oligopolistic pricing with sequential consumer search american economic review vol 79 no 4 pp 700 712 in a model of static firm competition in this paper we show that these standard welfare conclusions may be neutralized or reversed in a dynamic environment we focus on self enforcing collusion by firms and characterize the conditions under which collusive equilibria exist we show that less costly consumer search can facilitate firms abilities to collude resulting in higher prices and reduced consumer welfare even with imperfect or no monitoring by sellers of each other s prices if the same technology that eases consumer search also allows firms to monitor each other s prices more easily then firms can more easily detect cheating on a collusive price arrangement allowing an even greater scope for collusion this raises antitrust concerns with respect to the electronic marketplace and suggests that at least some of the anticipated competitive gains from electronic market systems may be difficult to realize

an econometric analysis of price differentials in the eec automobile market the paper investigates the sources of the observed price disparities in the eec automobile market on the basis of an oligopoly model with product differentiation this paper tests and fails to reject the hypothesis that automobile firms segregate national markets in the eec it is found that value added tax differentials and the existence of different import restraints quotas and vers are important contributing factors to price disparities on the contrary transportation cost differentials are not a significant explanatory variable finally the preference for domestic products or national brands is found as an important contributing factor in britain and itlay

theory and evidence on pricing by asymmetric oligopolies we present an analysis of markets with many asymmetrically positioned retailers that compete for the business of both informed and uninformed customers for a homogenous good such as software music book or a brand name appliance we show that two forms of asymmetry one related to loyal segment sizes of retailers and one related to the positioning of firms completely explain the observed price dispersion in such markets and the multitude of asymmetrical strategies adopted by retailers the stochastic dominance of empirical mixed strategy measures is used to test the theory with data on 968 books from 10 online retailers

price discrimination and retail configuration the hypothesis that price discrimination based on willingness to pay for quality can occur in multifirm markets is confirmed using microdata on gasoline retailing a test that discriminates between price structures associated with discrimination and with cost driven competitive differentials is developed and implemented with controls for variation in outlet and market characteristics a second test based on profitability variation rejects a competitive peak load pricing explanation for the observed price dispersion the data suggest that price discrimination at the retail level adds at least 9 a gallon to the average price of full service gasoline

ntbfs the french case abstract new technology based firms ntbfs represent only a small proportion of the firms established in france each year they attract very little specific attention from the national statistical apparatus and are considered to be of marginal significance by both the public authorities and financial institutions although the definition of ntbfs is problematic the available evidence suggests that the survival rate of technology based firms is higher than that of other start ups the most successful in terms of growth belong to dense and convergent networks through which they interact with larger firms and research organisations there is very little public policy specifically targeted on ntbfs in france instead public financing has been devoted mainly to the development of smes in general in support of their role in the creation of new employment and to supporting technology based firms both large and small to strengthen the international competitiveness of the french industry

foundations of dynamic monopoly and the coase conjecture subgame perfect equilibria are characterized for a market in which the seller quotes a price each period assume zero costs positive interest rate continuum of buyers and some technical conditions if buyers valuations are positive then equilibrium is unique buyers strategies are stationary and the price sequence is determinant along the equilibrium path but possibly randomized elsewhere otherwise a continuum of stationary equilibria can exist but at most one with analytic strategies coase s conjecture is verified for stationary strategies reducing the period length drives all prices to zero or the least valuation connections to bargaining models are described journal qf economic literature classification

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

cross national price differences for pharmaceuticals how large and why bilateral drug price and quantity indexes based on comprehensive data for seven countries us canada france germany italy japan and the uk refute the conventional wisdom that us drug prices are much higher than elsewhere for laspeyres us weighted indexes previous drug price comparisons are biased by unrepresentative samples and unweighted indexes quasi hedonic regression shows that cross national price differences reflect differences in product characteristics and in their implicit prices which reflect the regulatory regime strict price regulation systematically lowers prices for older molecules and globally diffused molecules generic competition lowers prices in less regulated regimes which also have more price elastic demand

can price dispersion be persistent in the internet markets we investigate pricing behaviour and market dynamics for both online branches of multi channel retailers mcrs and online only retailers dotcoms based on a set of panel data collected for 2 years in the online dvd market we find that prices of mcrs and dotcoms both go down with time but prices of mcrs decrease in a significantly faster speed implying that difference in the average prices between the two types of retailers is getting smaller with time we also compare the price dispersion and its dynamics between mcrs and dotcoms we find that the price dispersion among mcrs is much bigger than that among dotcoms at the beginning but such a difference gets smaller with time as the price dispersion among dotcoms becomes bigger our results suggest that the two types of retailers will not only charge similar average prices in long term but also have similar price dispersions but our findings show that price dispersion among all retailers goes up with time indicating that prices do not converge in

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

oligopolies and product durability abstract we analyze a simple two period quantity setting model where firms rent all of their output we compare the durability chosen by an oligopolist to the competitive socially optimal durability the model shows in subgame perfect equilibria the durability chosen by oligopolists will be cost minimizing independent of their output levels thus swan s independence result can be extended to oligopoly markets if the firms rent their output we also demonstrate the independence result can be extended to certain corner solutions

testing the market integration process in the european car sector evidence from pricing to market behaviour in this study we investigate the process of the european car market integration by analysing the evolution of cross country differences in the degree of pricing to market behaviour of united kingdom exporters we estimate these country differences by exploiting statistical information for pre tax retail prices and for export unit values conclusions from both independent data sets are in general quite consistent results support the claim that in the period before the block exemption regulation 1400 2002 came fully into force international price discrimination was an important source of car price dispersion within the euro area for a more recent period we found that estimated deviations in pricing to market behaviour across destinations have become lower this convergence suggests that car market integration was progressively improved at the end of the last decade

book value intertemporal pricing and quality discrimination in the us market for books abstract publishers produce books in hardcover and paperback versions with different prices and time of market introduction analysis of detailed book level data reveals that i price cost differentials cannot be explained by cost differences making this an example of quality discrimination ii market introduction time strongly affects sales suggesting that time is the crucial dimension of discrimination and iii there is substantial price rigidity across books and over time prices depend on cost shifters but not on demand shifters i discuss an explanation for this last finding in terms of the nature of demand in this market

modeling the search for the least costly opportunity abstract with the continuing growth in the number of opportunities available at virtual stores over the internet there is also a growing demand for the services of computer programs capable of scanning a large number of stores in a very short time we assume that the cost associated with each scan is linear in the number of stores scanned and that the resulting list of price quotes is not always satisfactory to the customer in which case an additional scan is performed and so on in such a reality the customer wishing to minimize her expected cost must specify the requested sample size and a rule control limit to stop the search in the context of search theory the above search model can be categorized as fixed sample size sequential with infinite horizon according to this model the expected search cost is a function of two decision variables the sample size and the control limit we prove that for arbitrary sample size the expected search cost is either quasi convex or strictly decreasing in the control limit and that the optimal expected search cost is quasi convex in the sample size these properties allow an efficient calculation of the optimal policy we also develop analytic formulas to calculate the cost s variance allowing customers to choose a slightly higher expected cost if there is a considerable decrease in the variance finally we present detailed examples for price quotes that are distributed uniformly or exponentially

exchange rate pass through at the product level we use a detailed database to investigate exchange rate pass through at the product level for a large number of countries the empirical analysis suggests that pricing behaviours are dichotomous with complete pass through in around 25 of sectors and significant pricing to market in the remaining ones average long run pass through coef ficient is close to 80 this result hides a strong heterogeneity of pass through behaviours across sectors even when composition effects are controlled for average pass through varies across importing countries the econometric analysis shows that pass through tends to be higher in volatile environments in less developed countries in weakly integrated markets jel classification f12 f31 f41

an economic theory of planned obsolescence planned obsolescence is the production of goods with uneconomically short useful lives so that customers will have to make repeat purchases however rational customers will pay for only the present value of the future services of a product therefore profit maximization seemingly implies producing any given flow of services as cheaply as possible with production involving efficient useful lives this paper shows why this analysis is incomplete and therefore incorrect monopolists are shown to desire uneconomically short useful lives for their goods oligopolists have the monopolist s incentive for short lives as well as a second incentive that may either increase or decrease their chosen durability however oligopolists can generally gain by colluding to reduce durability and increase rentals relative to sales some evidence is presented that appears to be generally consistent with the predictions of the theory

low cost airlines and online price dispersion abstract this paper presents a new form of online pricing tactic where airlines post at the same time and for the same flight fares in different currencies that violate the law of one price unexpectedly for an online market price dispersion may be accompanied by a hidden discount that tends to persist in the period preceding a flight s departure the econometric analysis reveals that airlines post dispersive fares in less competitive routes with more heterogeneous demand furthermore temporal persistence of intra firm fare dispersion suggests that it is an equilibrium phenomenon engendered by the airlines need to manage stochastic demand conditions for a specific flight

changing use of external business advice and government supports by smes in the 1990s bennett r j and robson p j a 2003 changing use of external business advice and government supports by smes in the 1990s reg studies 37 795 811 this paper uses cross sectional surveys of 1991 and 1997 a panel survey of firms surviving between 1991 and 1997 and comparison with a further cross sectional survey in 1999 to compare the levels of use by smes of external business advice the resource based theory of the firm indicates that smes seek advice in order to increase their competitive capacity over time increasing competition between smes is expected to lead to increasing use of advice however the paper demonstrates that only modest changes over time have occurred in aggregate use of external advice by smes and these are not statistically significant this suggests that earlier growth in external business advice services may now have plateaued there are some significant changes of use by source increasing for advertising personnel and recruitment new technology and computer servic

markup adjustment and exchange rate fluctuations evidence from panel data on automobile exports abstract this paper uses data on bilateral automobile export prices from the usa germany and japan to gauge the importance of markup adjustment driven by exchange rate movements across several destination markets we find that japanese exports are characterized by a high degree of markup adjustment designed to stabilize the price measured in the buyer s currency there is weak evidence for such behavior on the part of german exporters and no evidence of markup adjustment by us exporters where it exists markup adjustment tends to be highly persistent the dynamic pattern of markup adjustment is consistent with invoicing in the exporter s currency except for exports to the usa and canada

cross border integration in the european electricity market evidence from the pricing behavior of norwegian and swiss exporters abstract this paper examines the electricity market integration process in two european areas based on the pricing behavior of norwegian and swiss exporters the aim is to gain evidence for the period after the adoption of the second legislative package 2003 the pricing behavior of norwegian exporters indicates that the wholesale markets for denmark and sweden are highly integrated moreover results are fully compatible with the existence of a very competitive marketplace for electricity this clearly contrasts with the evidence provided by swiss exporters in this last case analysis revealed differences in pricing to market behavior between italy france and germany which indicates that exporters take advantage of international market segmentation and divergences between market structures this outcome provides a reasonable explanation as to why price differences between countries cannot be fully attributed to transmission costs as has been claimed in previous research we also found cross country convergence in levels of markups and in pricing to market behavior of the swiss exporters for the first part of the period that was analyzed the evidence is fully consistent with an initial impulse toward market integration originated by reforms implemented at the beginning of the last decade

sunk costs and regulation in the u s pesticide industry abstract this paper examines the impact of sunk costs and market demand on the number of innovative companies the u s market share of foreign based firms and merger choice in the u s pesticide industry results are consistent with sutton s 1991 view of sunk costs and market structure in that rising endogenous sunk research costs and exogenous sunk pesticide product regulation costs and declining demand negatively affect the number of firms in the industry have a stronger negative impact on the number of smaller firms and encourage foreign based firm expansion

durable goods monopoly with incomplete information this article reconsiders the durable goods monopoly problem when the monopolist s marginal cost is private information we show that the coase conjecture implies the no trade theorem in any equilibrium in which the lowest cost seller s initial offer approaches her marginal cost the aggregate probability of trade must vanish however we also construct non coasean equilibria which approximate the unique outcome of the rental version of the same model these stationary equilibria are comparatively efficient the results are equally applicable to the mathematically equivalent problem of sequential bargaining with two sided incomplete information where one party makes all the offers what are the consequences of monopoly in a market for a durable good present day understanding of this question divides into two strands of thought first the monopolist may effectively lack any ability to credibly precommit on her future output under this scenario the price will drop almost instantaneously to marginal cost apparently yielding the efficient outcome normally associated with perfect competition 1 second the monopolist may possess an explicit e g leasing the good rather than selling2 or implicit e g the maintenance of reputation3 device enabling her to adhere to an output restriction under such circumstances price will be maintained at a non competitively high level suggesting an outcome fraught with all the inefficiency of classical monopoly the conclusions of the first paragraph rest on analysis of a standard model in which the monopolist s payoff function is taken to be common knowledge a single firm with known constant marginal cost sells an infinitely durable good to consumers with a known distribution of valuations for the good 4 the firm has the ability to revise its posted price

a textbook example of international price discrimination we show that books for general audiences are similarly priced internationally but textbooks are substantially more expensive in the united states we argue that cost factors cannot explain this phenomenon and discuss several demand side explanations

arbitrage across borders why itunes gift cards sell above face value on ebay i introduction firms that operate internationally often charge different prices for the same product in different countries these price differences may be due to cost differences exchange rate fluctuations and or price discrimination where firms set prices based on consumers willingness to pay for the product there is an extensive literature on international price differences but nearly all of this research has focused on physical goods where arbitrage the situation where someone buys the product from a low price country and resells it to someone in a high price country tends to be relatively costly because of transaction costs including search costs and transportation costs there have been no empirical papers in the economics literature thus far on the arbitrage of downloadable goods this paper looks at the case of itunes which sells downloadable music videos books ipad and iphone applications and other content worldwide and shows how the sale of itunes gift cards above face value on the auction website ebay is linked to the arbitrage of itunes products itunes which is operated by apple first started selling music downloads in 2003 and by 2008 it was the largest music retailer in the united states and the world 1 people typically purchase products from their own country specific itunes stores but not all content is available in all countries due in part to licensing restrictions and consumer preferences e g itunes does not sell music movies and tv shows in many countries prices also vary across countries as detailed in section iii of this paper one can easily switch to any other country s itunes store with just a few mouse clicks in particular the u s store would seem to be a natural focal point and it tends to have lower prices and a wider selection however in order to actually purchase something from the u s store one needs to have either a u s credit card or a u s itunes gift card available in denominations ranging from 10 to 100 in the primary market through apple and its authorized sellers such as wal mart and best buy as such it can be surmised that some individuals outside the united states may be willing to purchase itunes gift cards on ebay in order to gain access to the u s store it should be noted that itunes terms and conditions specify that the u s store s products are available only to buyers in the united states we can see the evidence for this through the sale of itunes gift cards on ebay nearly 200 itunes gift cards are sold daily on ebay about 10 of all gift cards and more than half of these itunes gift cards sell above face value a phenomenon that is unusual among gift cards after discussing some background information and related literature this paper examines more than 1 300 ebay transactions in february 2011 and finds that itunes gift cards targeted to international buyers which are often sent electronically are more likely to have higher prices controlling for seller reputation shipping charges and other variables this indicates that non u s buyers are willing to pay a premium for the gift cards because they are unable to obtain them otherwise information about the buyers countries allows us to see whether it is the u s store s greater product availability or its lower prices that buyers are interested in this paper addresses an important issue because of the rising popularity of the sales of downloadable content worldwide this market includes music videos books video games and applications the internet has also made it easier for buyers and sellers in different countries to find one another and in the case of digital products exchange goods if arbitrage is widespread firms may decide to either minimize price differences between countries stop selling in low price countries altogether or use the legal system or other methods to prevent arbitrage in terms of the big picture this issue has implications for social welfare copyright enforcement and international trade policies and governments in some countries may also be concerned if their citizens have access to goods that are banned

incomplete exchange rate pass through and imperfect competition the effect of local production extent to which product prices respond to exchange rate induced changes in costs this research has revealed that the percentage change in the prices of imported goods is smaller than the percentage change in exchange rates of the exporting country and that price responses differ across destinations a phenomenon termed pricing to market this finding may indicate market imperfections in international trade for example those that may arise in the case of segmented markets alternatively these empirical facts may reflect the sale of products whose production occurs in multiple locations when firms are able to shift their production across borders or alter their location of sourcing their costs will not change one for one with home country exchange rate movements and therefore their prices are unlikely to change one for one with exchange rate movements however this possibility has not been addressed empirically in the literature on pricing to market this study contributes to the literature by estimating exchangerate pass through while controlling for local production in the destination market we focus on the u s automobile market and the pricing of u s and japanese firms in particular for several reasons first we have product level information on pricing and content and there is substantial variation in destination country production across products and over time second existing studies have found evidence of pricing to market and incomplete exchange rate passthrough in automobile markets providing a useful comparison for our results and making this an appropriate market in which to study the effect of local production on exchange rate passthrough consistent with other studies we find that japanese firms partially pass through japanese cost changes to their u s customers in addition we find that this partial pass through characterizes not only japanese cost shocks but cost shocks that these japanese firms experience in their u s production this finding persists in a sample that includes both u s and japanese firms automobile firms generally do not pass through cost shocks in their entirety our data also show that those japanese auto

price convergence in the european car market this article examines price convergence in the european union eu car market over the period 1995 to 2005 we find that there is a clear evidence of price convergence among the eu15 countries but not before 1999 moreover countries of the economic and monetary union emu started convergence previously to the eu15 as a whole finally exchange rate changes have significantly contributed to price dispersion over time across countries the results provide significant evidence that trade liberalization and the emu have enhanced the process of regional integration in the european automobile industry even though there is room for further measures to promote integration

beating irrationality does delegating to it alleviate the sunk cost effect we investigate the impact of delegating decision making to information technology it on an important human decision bias the sunk cost effect to address our research question we use a unique data set containing actual market transaction data for approximately 7 000 pay per bid auctions in contrast with the laboratory experiments of previous related studies our research presents the unique advantage of investigating the effects of it enabled automated bidding agents on the occurrence of a decision bias in real market transactions we identify normatively irrational decision scenarios and analyze consumer behavior in these situations our findings show that participants with a higher behavioral investment are more likely to violate the assumption of normative economic rationality because of the sunk cost effect more importantly we observe that the delegation of auction participation i e actual bidding to it significantly reduces the occurrence of the sunk cost effect in subsequent decisions made by the same individual we can attribute this reduction to the comparably lower behavioral investments incurred by auction participants who delegate their bidding to it in particular by mitigating different contributors of behavioral investments delegating to it reduces the likelihood of the occurrence of the sunk cost effect by more than 50 this paper was accepted by sandra slaughter information systems

a study in structural change relative earnings in wales since the 1970s the welsh economy has undergone rapid structural change in recent years this paper uses data from the new earnings survey to examine how earnings in wales changed relative to those of great britain between 1975 and 1994 there are five main findings first earnings of workers in wales have declined relative to those in great britain second the shift away from full time men has been an important factor in the fall in average relative earnings third the decline in the relative earnings of full time men is mostly explained by falling relative earnings in construction distribution and transport as well as the failure of workers in banking and financial services in wales to keep up with their counterparts in great britain fourth the shift in full time employment to health education and other services has tended to support relative earnings fifth the decline in full time men s earnings relative to great britain seems to have been caused by long run factors that are unlikely to naturally reverse the

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 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

calculating the real return on a sovereign wealth fund we present a new methodology for calculating the real return on sovereign wealth funds swf that share the investment objective of maximizing international purchasing power in terms of goods and services specifically we modify the traditional approach for deflating the nominal return along three dimensions the aggregator formula the measure of international prices and the weighting scheme we argue that a geometric average of price levels is an appropriate aggregator formula for capturing the deflationary effects of imports increasingly originating from low cost countries and that import prices paid by the swf owner and weights reflecting the owner s import pattern are consistent with the investment objective our proposed approach using the norwegian government pension fund global as an illustration raises the estimated average annual real rate of return over the sample period of 1998 2012 from 3 1 to 4 9

heterogeneous workers economic transformation and the stagnancy of transitional unemployment abstract in an environment of intense structural change being unemployed conveys a bad signal a simple model is developed which accounts for the stagnancy of the unemployment pool in transitional economies in spite of major worker reallocation occurring in these countries the model predicts that the tightening of unemployment benefits can hardly boost outflows to jobs once mass unemployment has built up as there are at this stage too many low productivity workers in the pool the implications of the model are consistent with evidence on gross job flows wage differentials and the effects of the tightening of unemployment benefit systems in eastern europe

do panels help solve the purchasing power parity puzzle although rogoff described the remarkable consensus of 3 to 5 year half lives of purchasing power parity ppp deviations among studies using long horizon data recent works using panel methods with post 1973 data report shorter half lives of 2 to 2 5 years but these studies do not use appropriate techniques to measure persistence we extend median unbiased estimation methods to the panel context calculate both point estimates and confidence intervals and provide strong evidence confirming rogoff s original claim although panel regressions provide more information on the persistence of real exchange rate shocks than univariate regressions they do not help solve the ppp puzzle

government advice networks for smes an assessment of the influence of local context on business link use impact and satisfaction business link in britain is one of the main recent government initiatives to support smes in the eu the paper uses a 1997 survey of smes to determine how business link use impact and satisfaction are influenced by firm characteristics local partnership characteristics local geographical context service intensity and other explanatory variables the paper presents econometric estimates based on logit and ordered logit models a key finding of the paper is to demonstrate that local context is not very significant to service use impact or satisfaction but local business link management and adviser performance are important influences on the impact and satisfaction major differences in the way smes use government backed services are also found there are high volumes of use of gateway information services producing only low impact and low volumes but high impacts and satisfaction with intensive advice services governed by contracts between the clients and the adviser implications for the small bus

third degree price discrimination in a short stay accommodation industry this article analyses the pricing in the short stay accommodation industry in tasmania it utilizes a novel 2008 survey of tasmanian short stay accommodation firms in which business managers were asked about their perception of the elasticity of their firm s demand in each of the market segments that their firm supplied this direct observation of elasticity allows us to demonstrate that firms price across market segments act in a manner consistent with the lerner index and the theory of third degree price discrimination further we show in line with expectations based on the literature that increased quality of the accommodation lowers the elasticity of demand while the elasticity of demand is higher in winter surprisingly internet sales channels do not exhibit a different elasticity of demand to other sales channels

the firm as a communication network this paper analyzes how organizations can minimize costs of processing and communicating information communication is costly because it takes time for an agent to absorb new information sent by others agents can reduce this time by specializing in the processing of particular types of information when these returns to specialization outweigh costs of communication it is efficient for several agents to collaborate within a firm it is shown that efficient networks involve centralization that individuals delegate tasks to subordinates only if they are overloaded and that the number of transits to the top tends to be equalized across individual information items

price discrimination with differentiated products definition and identification i introduction price discrimination is said to exist when the same product is sold to different consumers at different prices most economists also agree that price discrimination is at work when similar but not identical products are sold at prices that do not reflect differences in costs economics textbooks are rife with examples such as student or senior citizen discounts hardcover and paperback versions of books dinner versus lunch prices at restaurants airfares with various restrictions and price spreads of retail gasoline products on the other hand some economists have criticized the identification of such apparent price anomalies as price discrimination for example lott and roberts 1991 argue that there are usually cost based explanations for these phenomena and propose such explanations for the cases of airfare gasoline and restaurant prices nevertheless the authors do not challenge the conventional wisdom that price differences that cannot be explained by cost differences are discriminatory in recent years a number of papers have set out to empirically assess instances of alleged price discrimination the literature goes to great lengths to control for potential sources of cost variation among different products and thus to the extent that it is successful is not subject to the lott roberts critique almost all studies conclude that price discrimination is practiced in the particular market they analyze a skeptic of course could always argue that some sources of cost variation have not been accounted for and thus dismiss the results as erroneous despite the mild controversy over the methodology and its effectiveness the basic premise seems universally accepted the existence of price variation that cannot be explained by cost differences constitutes price discrimination this is not however a formal definition in fact there is no single widely accepted definition of price discrimination when products are not homogeneous some authors define price discrimination to exist when price cost margins absolute differences between differentiated products are unequal whereas others prefer to compare price cost markups percentage differences few authors have discussed the relative merits of one measure over the other 1 the relationship between the two has never been spelled out and the choice among them remains arbitrary in this article i aim to shed some light on this issue and provide some guidelines to empirical researchers interested in price discrimination i start by providing an overview of the current state of the literature in section ii i introduce the two competing definitions of price discrimination and briefly discuss the justification that has been provided for each i then review the empirical literature that uses one or the other definition as the basis of testing for price discrimination i present the basic methodology and discuss the definitional choices made by researchers investigating different market environments the picture that emerges from this overview is murky and provides little guidance to the empirical practitioner the absence of controversy on the choice of definition might simply reflect the fact that the two commonly used definitions are equivalent in section iii i show that this is not the case specifically it is possible for one definition to indicate the presence of price discrimination and for the other one to reject it it is also possible for the two measures to take opposite signs that is one product may have a higher markup and a lower margin than the other i also show that in general the margin criterion is more likely to indicate the presence of price discrimination i conclude that the choice of definition has important implications and should be given careful consideration the challenge is to come up with a consistent way of thinking about price discrimination that can easily be applied in a variety of settings

a panel study of firm growth among smes in networks an underlying assumption in sme literature as well as among policymakers is that networks are good per se especially for smes through accessing and utilising external resources in the network the sme can overcome some of the assumed disadvantages of limited size thus networking is assumed to enhance small firm performance and thereby small firm growth this article investigates this assumption analysis of panel data ascertains that a substantial number of smes are actively networking and that the level of networking has been maintained over a five year period in spite of this there is no evidence of associated short term benefits such as growth in employment or growth in total sales resulting from the networking activities the analyses suggest however that networking is associated with high growth in the geographic extension of markets which suggests that networking sustains long term objectives of the firms

a panel project on purchasing power parity mean reversion within and between countries abstract previous time series studies have shown evidence of mean reversion in real exchange rates deviations from purchasing power parity ppp appear to have half lives of approximately four years however the long samples required for statistical significance are unavailable for most currencies and are potentially inappropriate because of regime changes in this study we re examine deviations from ppp using a panel of 150 countries and 45 annual post wwii observations our panel shows strong evidence of mean reversion that is similar to that from long time series ppp deviations are eroded at a rate of approximately 15 annually i e their half life is around four years such findings can be masked in time series data but are relatively easy to find in cross sections

the timing of sales this paper presents a model of intertemporal price discrimination a fixed number of sellers produce a homogeneous good consumers with different preferences enter the market in each period and leave when they make a purchase the sellers typically vary their prices over time charging a high price in most periods but occasionally cutting the price to sell to a large group of customers with a low reservation price in some equilibria all stores lower their price at the same time and to the same level

regulated and unregulated substitutes aversion effects of an ethanol mandate i introduction regulation is a tool policymakers can use to steer markets away from private outcomes deemed to be socially suboptimal or inefficient regulations work either by altering market incentives or changing consumers choice sets as they attempt to reshape or restrict private market equilibria they can sometimes lead to unexpected consumer reactions and unanticipated consequences such as higher consumer costs or reduced effectiveness in meeting goals the extent to which a regulation can have adverse and unanticipated consequences depends on the nature and design of the regulation in this article we highlight a case where the design of an unpopular and hurried regulation led to especially adverse consequences the case is that of the recent ethanol mandate in the state of new south wales nsw australia ethanol mandates have become popular with legislators over the past decade and currently 62 countries have some form of one grfa 2014 a typical mandate requires producers to blend a certain percentage or certain volume of ethanol into the overall supply of gasoline the u s mandate for example requires 18 2 billion gallons of renewable fuels primarily ethanol be blended into the gasoline supply in 2014 up from 16 6 billion in 2013 epa 2013 the european union mandate requires 5 75 renewable fuels in gasoline by 2010 and 10 by 2020 eu 2003 2009 ethanol mandates have been controversial however griffin 2013 grafton kompas and van long 2012 rodriguez et al 2009 serra and zilberman 2013 westbrook et al 2014 and others proponents argue they help slow greenhouse gas accumulation promote renewable energy and reduce dependence on foreign oil they also point out benefits to the domestic farming and ethanol production industries which is sometimes a goal in itself critics on the other hand question their environmental value the need for fossil fuel replacement the lower energy yield and potential for food price inflation when crops grown for food are converted to ethanol use carter rausser and smith 2013 1 they also point out that ethanol blends tend to be more expensive for consumers on an energy adjusted basis than unblended gasoline mandates tend to be on net unpopular with consumers 2 an important consideration when transitioning to a new ethanol mandate or a higher ethanol blend under an existing mandate is ensuring compatibility with the vehicle fleet ethanol is an alcohol and in higher concentrations can be corrosive to engine valves seals and gaskets in older vehicles not designed with ethanol s properties in mind an option many jurisdictions have used in implementing ethanol mandates is to limit the ethanol blend to a level tested and widely believed to be compatible with the vast majority of vehicles on the road in the united states and canada for example a 10 blend has been implemented almost universally while a 5 blend has been used universally in many european countries if regulators instead deem that higher blends are desirable another option is to mandate that newly built vehicles be compatible with the new higher blend and then implement the fuel mandate once the vehicle fleet has largely turned over however vehicle turnover can take decades and this approach has not been as popular with regulators a third option that has found some favor is to introduce a higher ethanol blend that a majority of vehicles can use while still making the previous possibly ethanol free blend available as long as there are those who still need it in principle this dual blend approach promises to accommodate more aggressive ethanol mandates and lead to more ethanol in the fuel supply more quickly however we show that this kind of dual blend or selective mandate in its efforts to hurry ethanol blending beyond the capabilities of the vehicle fleet as a whole or beyond the confidence of consumers in its safety can have severe negative consequences

the impact of shopbot use on prices and price dispersion evidence from online book retailing abstract internet price search tools notably shopbots have reduced consumers search costs for price and product characteristics while a variety of analytic models predict that increased consumer search will lower price levels among competing retailers there is no consensus in the literature as to how price dispersion will change with increased consumer search moreover there are no papers that have empirically tested these predictions using direct observation of variation in shopbot use over time this paper examines the impact of changes in shopbot use over time on pricing behavior in the internet book market we do this by combining price and clickstream data collected from august 1999 to july 2001 a period of rapid expansion in shopbot use we find that a 1 increase in shopbot use is correlated with a 0 41 decrease in price levels and a 1 1 decrease in price dispersion

pricing to market behaviour in european car markets abstract this paper investigates ptm behaviour in european car markets for a period of great interest 1993 98 taking into account the role of invoicing currency the results indicate that local currency price stability is a strong and pervasive phenomenon across products independently of the invoicing currency the paper offers robustness checks tests and arguments that justify the interpretation of this finding at least in part as evidence of ptm it implies the existence of market segmentation and price discrimination despite the completion of the single market programme on 1 january 1993

pricing to market price discrimination or product differentiation we employ a vertical differentiation model to examine the potential bias in pricing to market results when using export unit values aggregating differentiated products our results show that i false evidence of pricing to market is always found when using unit values whether the law of one price holds or not and ii the size of the bias increases with the level of product differentiation our simulation results support those conceptual findings thus some of the positive pricing to market results in the literature could be an artifact of the product heterogeneity embodied in unit values rather than evidence of imperfect competition

small enterprise affiliations to business associations and the collective action problem revisited the objective of this study is to determine whether there is a consistent case for encouraging business representation through encompassing sector wide associations rather than narrowly constituted trade associations the study draws on evidence from a large scale survey of smes in new zealand to examine whether trade and sector associations attract different types of enterprise the motivations for membership the benefits obtained and how association membership can be made more attractive results suggest that each type of association appeals to a particular range of enterprises and that trade associations play a more diverse role than simply lobbying for a narrow constituency

list pricing and discounting in a bertrand edgeworth duopoly list or retail pricing is a widely used trading institution where firms announce a price that may be discounted at a later stage competition authorities view list pricing and discounting as a procompetitive practice we modify the standard bertrand edgeworth duopoly model to include list pricing and a subsequent discounting stage both firms first simultaneously choose a maximum list price and then decide whether to discount or not in a subsequent stage we show that list pricing works as a credible commitment device that induces a pure strategy outcome this is true for a general class of rationing rules further unlike the dominant firm interpretation of a price leader the low capacity firm may have incentives to commit to a low price and in this sense assume the role of a leader
