bilateral bargaining with externalities this paper provides an analysis of a non cooperative pairwise bargaining game between agents in a network we establish that there exists an equilibrium that generates a coalitional bargaining division of the reduced surplus that arises as a result of externalities between agents that is we provide a non cooperative justification for a cooperative division of a non cooperative surplus the resulting division is related to the myerson shapley value with properties that are particularly useful and tractable in applications we demonstrate this by examining buyer seller networks and vertical foreclosure

the role of firm size in bilateral bargaining a study of the cable television industry we examine the effect of buyer merger on bilateral negotiations between a supplier and n buyers merger may have bargaining effects in addition to the usual efficiency effects the effect of merger on the buyers bargaining position depends on the curvature of the supplier s gross surplus function merger enhances worsens the buyers bargaining position if the function is concave convex based on a panel of advertising revenue in the cable television industry our estimates indicate that the gross surplus function for suppliers of program services is convex this result suggests that cable operators integrate horizontally to realize efficiency gains rather than to enhance their bargaining position vis a vis program suppliers

an evolutionary approach to norms iorms provide a powerful mechanism for regulating conflict in groups even when there are more than two people and no central authority this paper investigates the emergence and stability of behavioral norms in the context of a game played by people of limited rationality the dynamics of this new norms game are analyzed with a computer simulation based upon the evolutionary principle that strategies shown to be relatively effective will be used more in the future than less effective strategies the results show the conditions under which norms can evolve and prove stable one interesting possibility is the employment of metanorms the willingness to punish someone who did not enforce a norm many historical examples of domestic and international norms are used to illustrate the wide variety of mechanisms that can support norms including metanorms dominance internalization deterrence social proof membership in groups law and reputation

pricing exports a cross country study abstract this paper applies cointegration and error correction analysis to estimate the long run steady state and short run dynamic relationships between the exchange rate and export prices in industrial and newly industrializing economies the data coherent analysis allowing the endogeneity of domestic cost and the exchange rate shows that the exchange rate has smaller effects on the export price than previous studies would indicate it contradicts some widely accepted relationships e g smaller more open countries have greater coefficients of pass through the results also exhibit important differences among the usa japan and germany in their export pricing behavior jel f30 f31

determinants of pro environmental consumption the role of reference groups and routine behavior abstract this paper investigates the determinants of pro environmental consumption focusing on the role of reference groups and routine behavior we study the factors that explain whether or not people have installed residential solar energy equipment or have subscribed to green electricity programs and the factors that influence the intensity of buying organic food in addition to demographic characteristics and environmental attitudes we consider the following categories of determinants economic and cognitive factors income estimated price premium level of information on environmentally friendly goods consumption patterns of reference persons own consumption patterns in the past using a unique data set from a survey conducted in the region of hanover germany we find the following 1 economic and cognitive factors are significant covariates of all three kinds of pro environmental consumption their influence is greatest in the case of green electricity 2 consumption patterns of reference persons are significant covariates of all three kinds of pro environmental consumption their influence is greatest in the case of organic food 3 the intensity of buying organic food is greater the longer people have been consumers of these goods

the dynamics of willingness to consume abstract it is increasingly acknowledged that the growing consumption in the north constitutes an important part of global environmental problems to improve the possibilities of dealing with this aspect of the problems this paper explores some of the driving forces behind the growth in consumption the first section introduces the environmental debate on consumption including the relationship between final consumption and the consumption of resources the recent political acceptance of dealing with consumption and the fundamental conditions for consumption growth in the north in the following sections a cross disciplinary approach is applied in a broad search for the driving forces behind the willingness to consume throughout the exposition two questions are explored 1 why are productivity increases largely transformed into income increases instead of more leisure 2 why is such a large part of these income increases used for the consumption of goods and services with a relatively high materials intensity instead of less material intensive alternatives the explanations are divided into three groups first the economic explanations including socio economic aspects related to the institutional set up of the economy second socio psychological explanations focusing on consumption from the perspective of the human being embedded in specific social relations third historical and socio technological explanations focusing on different aspects of everyday life the paper concludes with some reflections on the political implications of the analysis

hyteresis in import prices the beachhead effect this paper shows that temporary real exchange rate fluctuations can have persistent hysteretic effects on trade specifically when market entry costs are sunk sufficiently large exchange rate shocks alter domestic market structure and thereby induce hysteresis this simple result has strong implications for exchange rate theory t rade policy and estimation of trade equations empirical evidence su ggests that the recent dollar overvaluation induced hysteresis in u s import prices namely the aggregate pass through equation of exchange rates to import prices shifted in the 1980s the shift s nature and timing is broadly consistent with the hysteresis hypothesis copyright 1988 by american economic association

inflation targeting and exchange rate pass through this paper analyzes how endogenous imperfect exchange rate pass through affects inflation targeting optimal monetary policies in a new keynesian small open economy the paper shows that an inverse relation exists between the pass through and the insulation of the economy from foreign and monetary policy shocks and that imperfect pass through tends to decrease the variability of the terms of trade furthermore with cpi inflation targeting in the short run delayed pass through constrains monetary policy more than incomplete pass through and interest rate smoothing amplifies this effect when the pass through decreases the variability in economic activity tends to rise and the trade off between the stabilization of cpi inflation and output worsens in direct relation to how strictly the central bank is targeting cpi inflation in contrast with domestic inflation targeting optimal monetary policy is not constrained and opposite results occur consequently imperfect pass through favors the choice of domestic to cpi inflation targeting

not irrational but habitual the importance of behavioural lock in in energy consumption abstract a substantial body of literature has shown that our behaviour is often guided by habits the existence of habits not fully conscious forms of behaviour is important as it contradicts rational choice theory their presence thus calls for the setting of new instruments as they make it unlikely that consumers be capable of exercising control over their energy consumption in reaction to given incentives this is further increased in the evolutionary perspective where the current carbon based socio technical system constrains and shapes consumers choices through structural forces habits being potentially counterintentional they may explain the efficiency paradox in energy as well as the continued increase of energy consumption despite the rising environmental awareness among the population policies aiming at reducing energy consumption should thus specifically address the performance context of habits for instance targeting new residents has proven to be more effective given that their preceding habits have been disturbed the results of our empirical analysis confirm this idea by showing how a change of context makes people more receptive to a proposed measure our analysis of the role played by habits also suggests that individuals do not consider the need to change existing habits as an obstacle even though this is contradicted implicitly in the answers they provided to open questions this unconsciousness is one of the most delicate features of habits and it should thus be accounted for when designing measures given the other characteristics of habits the joint use of feedbacks and commitment strategies appears promising

beyond the economics of more the place of consumption in ecological economics abstract the relation between consumption and welfare generally assumed by orthodox economists must be re examined by ecological economists present attitudes towards consumption among the latter are often ambiguous resulting in a modified form of consumerism yet questioning the often dubious benefits of consumption is as important for the environmental debate as emphasising its neglected costs beyond basic needs satisfaction it is at most one s consumption level relative to others which counts for welfare so that benefits from consumption cannot be increased in the aggregate thus there is much scope for reducing consumption and thus environmental costs while increasing or maintaining welfare identifying those goods the consumption of which adds little or nothing to welfare and assessing the effect of reducing their consumption on resource use natural and human should be a major concern of an ecological economics aimed at promoting sustainable welfare

look at me saving the planet the imitation of visible green behavior and its impact on the climate value action gap abstract examining the regional distribution of 15 different greenhouse gas mitigation practices mps across australia we study the tendency for consumers to imitate visible pro environmental behavior in their local region while there is a great deal of variation in the specific type of mps adopted by consumers located in the same region anova results suggest that they tend to adopt a similar number of mps as their neighbours using discrete choice modelling our results suggest that this is due to the peer adoption of certain visible mps such as using public transport or car pooling encouraging agents to adopt other types of visible mps however the character of this spillover is limited in that visible pro environmental behavior does not appear to influence the adoption of non visible mps we also find that social imitation patterns help individuals overcome the observed gap between their stated concern about climate change and their propensity to act on this concern known as the climate value action gap policy implications for designing effective green nudges are discussed

price discrimination in the context of vertical differentiation an application to canadian wheat exports this study examines the ability of the canadian wheat board cwb to price discriminate in bread wheat exports this study models wheat as a vertically differentiated intermediate good and modifies the model of vertical differentiation by mussa and rosen to the realities of wheat import demand the conceptual model isolates the bases of price discrimination and demonstrates that the cwb s ability to exploit cost differences in pricing depends on the extent of the differentiation between canadian and u s wheat this model is implemented using monthly confidential price data provided by the cwb for exports to japan the united kingdom and two markets aggregating remaining exports through canada s west and east coasts for 1982 1994 the data indicate that the cwb charges different prices to different countries for wheat of the same grade and protein content results from the model indicate that the price difference between any two markets is not completely explained by elements of perfect competition however the evidence is mixed regarding the ability of the cwb to utilize all the instruments available to price discriminate thus the cwb s pricing strategy may be more complex and dynamic than the prescription for static producer surplus maximization derived in this study

on the irrelevance of input prices for make or buy decisions this paper demonstrates that input prices need not reflect the costs of an efficient incumbent supplier in order to induce entrants to implement efficient make or buy decisions because of strategic downstream considerations entrants may always undertake efficient make or buy decisions regardless of the prices at which they are authorized to buy key inputs from incumbent suppliers

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

incomplete pass through and the welfare effects of exchange rate variability abstract this paper considers the implications of incomplete exchange rate pass through for optimal monetary and exchange rate policy a two country model is presented which allows an explicit derivation of welfare functions in terms of a weighted sum of the second moments of producer prices and the nominal exchange rate from a single country perspective the optimal exchange rate variance depends on the degree of pass through the size and openness of the economy the elasticity of labour supply and the volatility of foreign producer prices welfare may be decreasing or increasing in the volatility of the exchange rate

conspicuous conservation the prius halo and willingness to pay for environmental bona fides abstract this paper develops a theory of conspicuous conservation a phenomenon related to conspicuous consumption in which individuals seek status through displays of austerity amid growing concern about environmental protection we identify a statistically and economically significant conspicuous conservation effect in vehicle purchase decisions and estimate a mean willingness to pay for the green signal provided by the distinctively designed toyota prius in the range of 430 4200 depending upon the owner s location results are related to the growing literature on green markets and suggest that policy should target less conspicuous conservation investments that will be under provided relative to those that confer a status benefit

pricing to market behaviour of india s high value agri food exporters an empirical analysis of major destination markets the pricing behaviour of india s high value agricultural and food exporters in their major destination markets is examined using a pricing to market ptm model for noncompetitive and exchange rate related pricing behaviour the analysis was undertaken in a context where india is showing high commodity concentration in agricultural trade the econometric analysis employed is panel corrected standard errors pcse estimation technique the results indicated evidence of a greater degree of imperfect competition either through price discrimination across destinations or through imperfect exchange rate pass through the analysis of exchange rate effects showed that the local currency price stabilization by the indian exporters were more prominent than the amplification of exchange rates the analysis of the asymmetric effects of exchange rates on export prices showed that in most cases the depreciation of indian rupee had a greater impact than the appreciation moreover the results showed that the exchange rate pass through is sensitive to the kind of exchange rate index utilised in our analysis we found that the commodity specific exchange rate better predicts the pricing to market behaviour in most cases

emerging differences in state grain trading australia and canada the australian wheat board awb and canadian wheat board cwb have attracted attention recently because they are two of the largest state trading enterprises stes engaged in agricultural trade they have traditionally been viewed as nearly sister agencies among major stes in the world market these two agencies historically had similar characteristics including price pooling cost pooling export sales monopolies monopoly powers within domestic markets grain quality control and government underwriting of initial producer prices and export credit however during the past 6 years similarities between the awb and cwb have begun to diverge and the importance of their differences is becoming increasingly apparent this paper identifies major emerging differences between the awb and cwb and explores potential explanations hypotheses for these dissimilarities a major point is that reforms in institutional design and legislative changes have given rise to emerging differences in key aspects of the marketing systems and performance

socio technical inertia understanding the barriers to electric vehicles it is widely accepted that electrification of the transport sector is one of several technological trajectories that could redress some of the environmental issues associated with the growth in travel demand including climate change and oil demand at a global scale and air quality and noise pollution at the urban scale electric vehicles have been considered a promising technology at repeated intervals over the last century but this promise has not been realised this paper is a contribution to understanding the key tools and strategies that might enable the successful introduction of new technologies and innovations by exploring the key barriers to electric vehicles encountered in two countries uk and germany where the automobile industry has been historically significant the study evaluates stakeholders opinions on relevant regulation infrastructure investment r d incentives and consumer incentives the key findings of the research are that the introduction and penetration of evs is confronted by several barriers that inhibit a larger market penetration under current conditions which in turn casts doubt on the assumptions of strategic niche management and transitions theory

macroeconomic aspects of exchange rate pass through abstract this paper addresses the cause of the variability in exchange rate pass through we develop a model in which foreign exporters setting prices under uncertainty infer the value of domestic income and prices based upon their observation of the exchange rate and their knowledge of the stochastic structure of the economy this inference problem links pass through to the underlying stochastic macroeconomic structure of the economy rather than the source direction or size of the endogenous exchange rate movement that period the predictions of the model are consistent with pass through experience in the united states during the past decade

exchange rate shocks and the speed of trade price adjustment 1 introduction theoretical and empirical work in the international trade literature dealing with the relationship between exchange rate and trade prices has been dominated and guided by the static pass through and profit markup model see e g feinberg 1986 mann 1986 fisher 1989 hooper and mann 1989 knetter 1989 gagnon and knetter 1995 feenstra gagnon and knetter 1996 and lee 1997 the shortcoming of such models is well captured by william branson 1989 p 333 difference in adjustment response signals to me the need for a reconsideration of the theoretical framework for the analysis of the pass through question by now we should be thinking about optimizing price policy for investors and exporters who know that they face an exchange rate that follows some sort of stochastic process over time these differences call for a revision of pass through theory along the lines of time series analysis our explicit incorporation of profit maximizing firms facing adjustment costs develops the model introduced by krugman 1987 it transforms the traditional markup and pass through model to explain from first principles a dynamic markup and a price adjustment speed both depending on fundamental characteristics of the firms involved krugman 1989 concludes his paper on pricing to market by calling for further research on the adjustment cost model regarding the adjustment cost approach he states krugman 1989 p 44 it is still a speculative idea not grounded in solid empirical tests but it is a good story and if it is correct it has extremely important implications for economic policy the present paper provides the quantity adjustment cost approach that krugman calls for as such it complements the work of gagnon 1989 and kasa 1992 while gagnon and kasa employ quantity adjustment cost models with many of the same features as the model developed here they provide only approximate solutions and focus on a quite different set of issues gagnon examines the effect of exchange rate variability on trade volume kasa investigates the importance of mean reversion in exchange rates as an explanation for the pricing to market hypothesis in contrast our focus is on the relation between adjustment speeds and pass through thus our contribution relative to gagnon 1989 and kasa 1992 is that we provide the passthrough issue in a dynamic context with exact analytical solutions that relate the degree of passthrough to adjustment speeds and identify the determinants of commodity specific adjustment speeds in response to exchange rate shocks the remainder of the paper is organized as follows in section 2 we develop a partial equilibrium model taking exchange rates as given of the pricing policies of a profit maximizing firm competing in foreign markets and subject to a convex quantity adjustment cost section 3 develops testable implications directly from the model section 4 discusses the data and empirical methodology for preliminary two stage time series and cross sectional tests section 5 provides the tentative estimation and section 6 concludes 2 a simple partial equilibrium model consider a representative firm producing fox export that maximizes the expected discounted value of infinite horizon real profits the firm generates its revenue abroad in foreign currency it has no influence on the exchange rate may adjust its price at any point in time but is subject to a convex cost of quantity adjustment the firm maximizes where x is the exogenously given real exchange rate at time t we define x as the units of domestic currency per unit of foreign currency multiplied by the export destination country s price index and divided by the home country s price index instantaneous profits are discounted at a rate r which is specific to the firm this rate accounts for a standard risk premium inherent in the riskiness of the firm s activities

measurement of monopoly behavior an application to the cigarette industry a simple scheme is proposed to measure monopoly pricing behavior the coefficient of the tax rate term in a price equation identifies the ratio of price to marginal cost no direct measurement of costs is required so a major problem for other empirical studies of monopoly is avoided empirical results for cross section time series data support rejection of atomistic competition but also provide evidence against the operation of an effective cartel in the cigarette industry the model represents an alternative interpretation of related results in a recent paper by barzel application of the methodology to other markets is feasible

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

for better or for worse empirical evidence of moral licensing in a behavioral energy conservation campaign isolated environmental campaigns focusing on defined target behaviors are rolled out to millions of households every year yet it is still unclear whether these programs trigger cross domain adoption of additional environment friendly behaviors positive spillover or reduced engagement elsewhere a thorough evaluation of the real net performance of these programs is lacking this paper investigates whether positive or perverse side effects dominate by exemplifying the impact of a water conservation campaign on electricity consumption the study draws on daily water 10 780 data points and weekly electricity 1386 data points consumption data of 154 apartments in a controlled field experiment at a multifamily residence the results show that residents who received weekly feedback on their water consumption lowered their water use 6 0 on average but at the same time increased their electricity consumption by 5 6 compared with control subjects income effects can be excluded while follow up research is needed on the precise mechanism of the psychological process at work the findings are consistent with the concept of moral licensing which can more than offset the benefits of focused energy efficiency campaigns at least in the short term we advocate the adoption of a more comprehensive view in environmental program design evaluation in order to quantify and mitigate these unintended effects

willing consumers or locked in policies for a sustainable consumption postmodern explanations of consumer behaviour stress social and psychological factors to the neglect of explanations based on structural issues such as the working life conditions which favour a work and spend lifestyle the conditions of urban living or the effects of pervasive marketing this paper argues that consumers may not be so keen and willing but are rather locked in by circumstances some of these circumstances are deliberately created by other interests and a policy to limit consumption must look for adequate means over a large and varied field in the end shorter working hours may be an important key to a more sustainable future 2002 elsevier science b v all rights reserved

terms of trade and real exchange rates the canadian evidence abstract this paper presents empirical evidence linking the canada us real exchange rate with the terms of trade using recently developed econometric methods for nondashstationary data we find that the real exchange rate is cointegrated with terms of trade variables and that causality runs from the terms of trade to the exchange rate we then construct a simple exchange rate equation that satisfies several specification tests and performs better than a random walk in post sample forecasting experiments the results suggest that much of the variation in the real exchange rate is attributable to movements in the terms of trade and that the influence of monetary factors is secondary

exchange rate expectations and market shares abstract we consider an asymmetric duopoly comprised of a domestic and a foreign firm we derive optimal collusion equilibria and examine how market shares vary in response to changes in the exchange rate our analysis implies some surprising results first a temporary depreciation has a greater impact on market shares than a permanent depreciation second if the change in the expected future rates is of sufficient magnitude then the domestic firm s market share may decrease following a depreciation of the home currency a seemingly perverse effect 1997 elsevier science s a

the response of the us export prices to changes in the dollar s effective exchange rate further evidence from industry level data the relationship between the dollar s effective exchange rate and the export price indexes for 13 two digit us manufacturing industries is analysed to determine i which industry adjusts its dollar export price to dampen or amplify the effect of the exchange rate fluctuations on the foreign currency price of its exports and ii whether the response of the export price index to appreciation and depreciation of the exchange rate is asymmetric for several industries evidence consistent with dampening the foreign currency price of exports in an asymmetric fashion is found the implications of the results for the price competitiveness of the industries studied is discussed

the information content of the interest rate and optimal monetary policy optimal monetary policy rules are derived in a rational expectations cum contracting framework monetary policy is redundant if wage setters exploit the incomplete current information embodied in today s nominal interest rate however the monetary authorities can save wage setters the costs of indexing to the interest rate a contemporaneous money supply feedback rule is as effective as wage indexation a lagged rule relevant under a regime of money supply targeting is also as effective if investors use the interest rate both rules have the same implications for the real interest rate as poole s combination policy however the two rules have strikingly different implications for the nominal interest rate

do vertical mergers facilitate upstream collusion we investigate the impact of vertical mergers on upstream firms ability to collude when selling to downstream firms in a repeated game we show that vertical mergers give rise to an outlets effect the deviation profits of cheating unintegrated firms are reduced as these firms can no longer profitably sell to the downstream affiliates of their integrated rivals vertical mergers also result in an opposing punishment effect integrated firms typically make more profit in the punishment phase than unintegrated upstream firms the net result of these effects in an unintegrated industry is to facilitate upstream collusion we provide conditions under which further vertical integration also facilitates collusion

optimal price and inventory adjustment in an open economy model of the business cycle this paper presents a macroeconomic model containing optimizing inventory holding firms that is consistent with a number of prominent empirical regularities concerning fluctuations in output exchange rates relative prices and money prices are sticky but they are not predetermined still our model is consistent with exchange rate overshooting in the sense of dornbusch typical sticky price models allow a divergence between current production and current demand but this divergence is never allowed to feed back into the model our optimal inventory adjustments reconcile divergences between current demand and production and the inventory stock movements provide expected future dynamics

sufficiency and consumer behaviour from theory to policy abstract it is increasingly obvious that for safeguarding environmental sustainability eco efficiency measures will need to be complemented by sufficiency in particular by strong sustainable consumption the theory of planned behaviour tpb and social practice theory spt offer different views on consumer behaviour and on ways to change it this paper briefly describes the challenges discusses the applicability of both theories and their meaningfulness for policy recommendations we suggest an approach combining results of both bodies of theory complemented by ideas from political economy to substantiate the prism of sustainable consumption we introduce as a heuristic sufficiency policy tool it is useful to identify affordability criteria for change in each dimension as the basis for deriving suggestions for effective policy interventions we conclude that i effective interventions are possible ii they have to address several dimensions of affordability simultaneously and iii the sufficiency policy space prism can be a useful tool in structuring planned interventions

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

aggregate information and the role of monetary policy in an open economy a model of a small open economy in which agents trade in local goods markets and an economy wide asset market is developed purchasing power parity is assumed to hold at the aggregate level however because of local deviations from purchasing power parity agents possess differential information using this framework it is shown that when the exchange rate is flexible monetary policy can influence the distribution of real output by altering the information content of the exchange rate however when monetary policy is committed to fixing the exchange rate by a feedback rule the distribution of real output is independent of the particular exchange rate rule chosen the stability of real output under the two regimes is compared and it is demonstrated that regardless of the stability of domestic monetary policy a flexible exchange rate regime is superior in this respect possible qualifications and extensions of these results are also discussed

does work life balance affect pro environmental behaviour evidence for the uk using longitudinal microdata abstract the environmental challenges we face today have made the need to behave pro environmentally increasingly salient many believe that the modern day busyness of life and lack of spare time have kept people from acting according to their values and behaving more pro environmentally this study uses microdata from the uk household longitudinal study ukhls to investigate the relation between pro environmental behaviour environmental self perception and work life balance pro environmental behaviour covers 21 behaviours relating to home energy personal transport recycling and shopping work life balance is defined with relation to the availability of discretionary time using both objective and subjective measures the results from the regression models of overall pro environmental behaviour suggest that work life imbalance does not appear to affect neither directly nor indirectly through environmental values and attitudes pro environmental behaviour the main factors determining the extent of pro environmental behaviour relate to individual s attitudes towards the environment age educational attainment household income and the presence of young children the sensitivity analysis looking at differing time demanding behaviours reveals that actual availability of discretionary time does not seem to affect pro environmental behaviour while the subjective experience of work life imbalance can have a negative direct effect particularly for more time demanding pro environmental behaviours

a test of conspicuous consumption visibility and income elasticities abstract this paper shows that consistent with a signaling by consuming model a la veblen income elasticities can be predicted from the visibility of consumer expenditures we outline a stylized conspicuous consumption model where income elasticity is endogenously predicted to be higher if a good is visible and lower if it is not we then develop a survey based measure of expenditure visibility ranking different expenditures by how noticeable they are to others finally we show that our visibility measure predicts up to one third of the observed variation in elasticities across consumption categories in u s data

exchange rate hysteresis large versus small policy misalignments abstract using a monetary model in the spirit of dornbusch 1976 and a sunk cost model of trade hysteresis we show that a sufficiently large policy misalignment can induce hysteresis in the trade balance and thereby alter the steady state real exchange rate hence exchange rate dynamics are path dependent since hysteresis in our model can entail industrial dislocation and the scrapping of sunk assets we suggest that these factors constitute a welfare cost of large policy misalignments that have not been considered formally additionally since the long run exchange rate is path dependent standard empirical tests of exchange rate models may involve a misspecification

can sustainable consumption be learned a model of cultural evolution abstract this paper shows how sustainable consumption patterns can spread within a population via processes of social learning even though a strong individual learning bias may favor environmentally harmful products we present a model depicting how the biased transmission of different behaviors via individual and social learning influences agents consumption behavior the underlying learning biases can be traced back to evolved cognitive dispositions challenging the vision of a permanent transition toward sustainability we argue that green consumption patterns are not self reinforcing and cannot be locked in permanently

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

cost raising strategies advantage rivals by raising their costs in this paper we show that strategies designed to raise rivals costs have a number of advantages over predatory pricing they are credible do not necessarily require the victim to exit and do not necessarily require the existence of classical market power the paper sets up a general model proves a number of general results and then applies the model to specific strategies involving overbuying inputs and vertical integration

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

declining exchange rate pass through to u s import prices the potential role of global factors this paper documents a robust and sustained decline in exchange rate pass through to u s import prices from well above 0 5 during the 1970s and 1980s to around 0 2 over the last decade we attribute this decline to the rising prominence of competition from china a shift in import pricing behavior since the asian financial crisis and the reduced share of material intensive goods in u s imports we also find evidence that foreign exporters are increasingly setting their prices with an eye on u s prices these results in turn suggest a new and more general hypothesis linking the decline in pass through to the evolving nature of competition in global markets and structural changes in international production patterns

a larger slice or a larger pie an empirical investigation of bargaining power in the distribution channel this research aims to provide insights into the determinants of channel profitability and the relative power in the channel by considering consumer demand and the interactions between manufacturers and retailers in an equilibrium model we use the nash bargaining solution to determine wholesale prices and thus how margins are split in the channel equilibrium margins are a function of demand primitives and of retailer and manufacturer bargaining power bargaining power is itself a function of exogenous retail and manufacturer characteristics the parties bargaining positions are determined endogenously from the estimated substitution patterns on the demand side the more they have to lose in a negotiation relative to an outside option the weaker the bargaining position we use the proposed bargaining model to investigate the role of the three main factors that have been blamed for the power shift from manufacturers to retailers in recent years firm size increases store brand introductions and service level differentiation in our empirical analysis of the german market for coffee we find that bargaining power varies among the different manufacturer retailer pairs this result suggests that bargaining power is not an inherent characteristic of a firm but rather depends on the negotiation partner we are able to confirm empirically previous theoretical findings that there can be cases where the slice of the pie that goes to one of the channel members may decrease but the overall pie increases and compensates for the smaller share of profits

currency areas and monetary coordination we integrate a monetary search model into open economy macro to analyze the gains from coordinating on inflation search frictions and local congestion lead to a determinate exchange rate between two currencies relative prices deviate from the law of one price because the deviations depend on the cross country differential in money growth each country is tempted to inflate to exploit the deviations policy coordination reduces inflation and improves welfare for all countries in contrast to traditional models the gains from coordination continue to exist even after each country optimally sets a direct tax on the foreign use of the country s currency

mergers when prices are negotiated evidence from the hospital industry in recent years many hospitals have merged in part to gain bargaining leverage with managed care organizations mcos we investigate the price impact of hospital mergers by formulating and estimating an equilibrium bargaining model between hospital systems and managed care health insurers over prices for inpatient services we estimate the parameters of the model using claims and discharge data from northern virginia in 2006 inova health system proposed to acquire prince william hospital we nd that this merger would have raised prices signicantly and that the remedy of separate bargaining imposed by the ftc in a separate hospital case would have resulted in a larger price increase

exchange rates and market power evidence from the petrochemical industry abstract this paper takes a microeconometric approach to the study of exchange rate pass through in imperfectly competitive markets we provide evidence for the hypothesis that incomplete exchange rate pass through can be attributed to non competitive conduct by foreign firms a unique feature of our approach is the use of highly disaggregated industry data which is compatible with the behavioral assumptions of a homogeneous product oligopoly model we employ a panel data set consisting of location and product specific price and cost data for 29 traded petrochemicals for the us germany and japan during 1982 to 1993 our empirical estimates indicate that german and japanese firms exercised statistically significant market power in the us petrochemical market during our sample period

did the strong dollar increase competition in u s product markets sunk cost models of new trade theory have demonstrated that large unanticipated swings in currency values can have permanent effects on trade flows by altering market structure in imperfectly competitive markets the author tests an implication of these models using panel data on export unit values from germany and japan to a number of foreign markets including the united states he finds weak evidence in support of the thesis that u s product markets became more competitive as a result of the large dollar appreciation of the 1980s although the results vary by industry and comparison country copyright 1994 by mit press

the value of environmental status signaling how much are consumers willing to pay to signal their environmental consciousness we identify the signaling value of an environmental public good by focusing on hybrid cars and exploiting the physical uniqueness of the toyota prius relative to hybrids that look identical to their non hybrid counterparts we deploy a quasi experimental hedonic model to estimate this willingness to pay we find that controlling for observable and unobservable factors the prius commands an environmental signaling value of 587 or 4 5 of its value our research provides lessons for economists and policymakers and contributes to the literature on identifying signaling values

the market for preferences learning processes are widely held to be the mechanism by which boundedly rational agents adapt to environmental changes we argue that this same outcome might also be achieved by a different mechanism namely specialisation and the division of knowledge which we here extend to the consumer side of the economy we distinguish between high level preferences and low level preferences as nested systems of rules used to solve particular choice problems we argue that agents while sovereign in high level preferences may often find it expedient to acquire in a pseudo market the low level preferences in order to make good choices when purchasing complex commodities about which they have little or no experience a market for preferences arises when environmental complexity overwhelms learning possibilities and leads agents to make use of other people s specialised knowledge and decision rules

nash in nash bargaining a microfoundation for applied work a nash equilibrium in nash bargains has become the workhorse bargaining model in applied analyses of bilateral oligopoly this paper proposes a non cooperative foundation for nash in nash bargaining that extends the rubinstein 1982 model to multiple upstream and downstream rms assuming there exists gains from trade for each rm pair we prove that there exists an equilibrium with immediate agreement and negotiated prices that correspond to rubinstein prices if and only if the marginal contribution of a set of agreements is weakly greater than the sum of the agreements marginal contributions we provide stronger conditions under which equilibrium prices are unique

a new look at pass through abstract this paper examines the relationship between exchange rates and prices rather than assuming exchange rate changes are exogenous shocks that affect prices i use a long run restrictions var to identify shocks and explore the way domestic prices import prices and exchange rates react to a variety of shocks consumer price pass through is nearly complete in response to some shocks but low in response to others alternatively import prices and exchange rates typically respond in the same direction and pass through seems quick this supports the idea that import prices are set in the producer s currency and that lower cpi pass through is a result of changes in quantities or margins further down the supply chain

the effects of neighbour influence and cultural consumption on separate waste collection theoretical framework and empirical investigation abstract separate waste collection swc is a policy priority for eu countries this work investigates the effect of neighbour influence and cultural consumption on municipal swc with a twofold focus first it outlines a simple theoretical framework where the motivations underlying pro environmental behaviours are influence by neighbour effects and cultural consumption second it tests the theoretical results implementing a quantile regression on italian municipal data for 2012 the results confirm that neighbours influence each other while different cultural goods produce different effects these findings indicate that the cultural policy may play a relevant role in tackling environmental issues

linear and nonlinear exchange rate exposure abstract this paper presents a new methodological approach to examine exchange rate exposure which takes account of the role of the market portfolio and macroeconomic variables in exposure regressions exchange rate regimes based on periods of depreciation and appreciation and nonlinear exposure within each regime we show that the stock market s own exposure to exchange rates should be taken into account before considering industry exposure in addition we adjust the exchange rate and the stock market for common economy wide factors that are unrelated to exchange rates within this framework we show that exposure to bilateral exchange rates is statistically and economically important and that industries with extensive international trade are more often exposed than industries with low levels of international trade the signs of exposure coefficients in each regime are consistent with the extent to which an industry exports we also show that nonlinear exposure is often statistically and economically significant interestingly there is little evidence that industries are exposed to a currency basket

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

incidents of gray market activity among u s exporters occurrences characteristics and consequences each year the value of gray market products sold throughout the world runs into the billions of dollars past research has stated that exporters of manufactured goods can hardly afford to ignore the possibility of this phenomenon due to the often severe effects on their sales volume margins and relationships with distributors and end users through a survey of export managers of manufacturing firms coupled with a series of qualitative interviews this study investigates how organizational specific control specific and market specific factors drive gray market activity and in turn explores the effects of unauthorized distribution on export performance several factors are shown to evaluate the potential of unauthorized distribution in their export markets namely the centralization of decision making the degree to which the product is standardized channel integration and channel control international experience market volatility and the number of markets served were found to have no effect on gray market activity this contrary to traditional thinking furthermore the effects of gray market activity on strategic versus economic performance is shown to be significantly different each of these issues is discussed in detail along with the implications for export managers

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

the short run and long run effects of behavioral interventions experimental evidence from energy conservation we document three remarkable features of the opower program in which social comparison based home energy reports are repeatedly mailed to more than six million households nationwide first initial reports cause high frequency action and backsliding but these cycles attenuate over time second if reports are discontinued after two years effects are relatively persistent decaying at 10 20 percent per year third consumers are slow to habituate they continue to respond to repeated treatment even after two years we show that the previous conservative assumptions about post intervention persistence had dramatically understated cost effectiveness and illustrate how empirical estimates can optimize program design jel d12 d83 l94 q41

ppp strikes back aggregation and the real exchange rate we show the importance of a dynamic aggregation bias in accounting for the ppp puzzle we prove that the aggregate real exchange rate is persistent because its components have heterogeneous dynamics established time series and panel methods fail to control for this using eurostat data we find that when heterogeneity is taken into account the estimated persistence of real exchange rates falls dramatically its half life for instance may fall to as low as eleven months significantly below the consensus view of three to five years

import pricing and the trade balance in a popular model of exchange rate determination abstract this paper extends a popular model of exchange rate determination to include an import pricing relationship that is consistenc with imperfect competition in the importable sector the analysis highlights how import pricing behavior and aggregate macroeconomic relationships interact in determining the dynamics of the exchange rate the price of imports and the trade balance a basic prediction of the analysis is that an increase in the substitutability of imported product varieties in the domestic market will raise the responsiveness of the exchange rate and dampen the responsiveness of the trade account to monetary shocks

an empirical model of mark ups in a quality differentiated export market abstract this paper develops an empirical model to allow for imperfect competition in the market for traded goods a simultaneous equation model incorporating the demand for and supply of taiwanese footwear exports to the united states is specified and estimated the model allows the identification of two separate sources of mark ups in export prices the first comes from the u s imposed quantitative restriction on these exports the second comes from imperfect competition in the international market for these exports the results suggest competitive behavior by taiwanese footwear exporters the quantitative restriction resulted in a 16 9 percent mark up of prices over marginal cost

the growth of network computing quality adjusted price changes for network servers in this paper we investigate the evolution of quality adjusted prices for servers motivated by two facts first the productivity acceleration in the us economy since the mid 1990s is closely linked to spread of information technology of which networked computing is a large component second the growth of network computing itself has been fostered by the rapid growth in the quality and quantity of the network server market like pakes 2003 analysis of the pc market we show that our preferred version of the hedonic price index complete hybrid fell much more rapidly than the standard matched model price index the hedonic index fell on average by about 30 per annum compared to 17 p a for the matched model this difference is mainly due to the selection bias in the standard matched model price index due to the exit of obsolete models which would have had the fastest price falls

measuring the intensity of competition in export markets abstract this paper develops an approach to measuring the intensity of competition in international markets using readily available data on destination specific values and quantities of exports at the seven digit industry level the intensity of competition a group of exporters faces in a particular export market is measured by the residual demand elasticity the group faces this elasticity is identified by exchange rate shocks which rotate the supply relation of the source country export group relative to competitors located in other countries we apply this method to german exports of beer and us exports of linerboard paper the resulting estimates of market power appear to be plausible and consistent with other indicators of competition e g market shares the number of competitors providing support for the applicability of our framework in measuring competition in international markets

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

a note on the effect of cost changes on prices in a recent article in this journal sumner 1981 took an ingenious approach to estimating the level of monopoly power in the cigarette industry he noted that differences in marginal costs exist in the industry due to varying levels of state taxes the sales prices established will satisfy the equation p i liq l mr mc where p price and q the elasticity of demand for the product in question if elasticity is a constant observing the change in marginal cost and the change in price enables one to infer the elasticity of demand perceived by the firm elasticity could then be used as a proxy for the firm s market power this technique turns out to be of very limited applicability however because it is extremely sensitive to the functional form assumed for the demand curve consider the general problem of a firm facing constant marginal costs of c in maximizing profits the firm solves

technological diffusion and preference learning in the world of homo sustinens the challenges for politics abstract this article relates agents learning of a preference for a technology competition of technologies and their relative diffusion among potential adopters competitive interactions between two technologies are captured by an extended lotka volterra model to also incorporate preference learning on the part of potential adopters of these technologies we combine it with a model of cultural learning based on role model conformist and hedonistic learning our theoretical analysis is illustrated by a concrete example the competition between electric mobility and conventional forms of individual mobility the model enables an evaluation of specific policy instruments as to the promotion of sustainable technology

cost pass through in the u s automobile market we study cost pass through in the u s automobile market using a framework that incorporates the effects of cost changes on input decisions we find that accounting for firms factor market decisions significantly increases measured cost pass through although we reject the hypothesis of full cost pass through and constant markups in addition our evidence suggests that cost shocks common to all manufacturers have a greater effect on prices than do model specific cost shocks finally we examine how pass through varies with manufacturer nationality finding that u s firm cost pass through exceeds that of european and asian firms

international deviations from the law of one price the role of search frictions and market share this article examines the size and persistence of international deviations from the law of one price in an industry with search frictions cost differences lead foreign and domestic firms to price differently within countries when local firms are more common in each country there are large and persistent price differences across countries large and persistent changes in international relative costs lead to large and persistent changes in international relative prices dynamic considerations imply that the amount of a cost shock firms pass through to prices is u shaped in the market share of firms receiving the shock

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

the competitive structure of u s agricultural exports the competitive structure of u s agricultural exports is examined using a model of exporter behavior based on pricing decisions across destination markets market power is revealed in the adjustment patterns of export prices in response to exchange rate movements the results reject the hypothesis that the export pricing decisions by u s firms are consistent with price discrimination across destination markets for cotton corn and soybeans the strongest evidence against the competitive market structure is obtained for international trade in wheat where results indicate that the two largest importers soviet union and prc may exert market power to obtain lower prices

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

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

on the economics of sustainability abstract the purpose of this paper is to work toward reconciliation of the neoclassical consumer choice axiom that more is better and the ecological concern that more is not sustainable the key is to divide the desired more into its rival and nonrival components for it is the consumption of rival goods such as plastic that strains the ecosystem in contrast the consumption of nonrival goods such as bird watching leaves little to no footprint while sustainability can be enhanced through changing preferences a menu of taxes subsidies and or vouchers can also motivate greater nonrival consumption and therefore sustainability without reducing consumer welfare

vertical bargaining and retail competition what drives countervailing power this article investigates the effects of changes in market concentration on the equilibrium prices in a supply chain results are derived from a theoretical model of bilateral bargaining between upstream and downstream firms which allows for general forms of demand and retail competition whether countervailing buyer power arises in the form of lower input prices following greater concentration downstream depends on the pass through rate of input prices to retail prices countervailing buyer power generally does not translate into lower retail prices because of heightened market power at the retail level
