electricity liberalisation in europe how competitive will it be all the countries of western europe have taken steps to liberalise their electricity industries large consumers in every country can choose their electricity supplier and in some countries this choice has been extended to every consumer the european union has decided that from 2007 at the latest all customers will be able to choose their electricity supplier a number of large european electricity companies have been responding to this changing environment by merging with electricity companies in other countries this means that while some national markets may not look unduly concentrated concentration at the european level has been growing this paper addresses the reasons for this and asks whether the resulting industry structure will be sufficiently competitive to deliver gains from liberalisation

behavioural development economics lessons from field labs in the developing world abstract explanations of poverty growth and development depend on the assumptions made about individual preferences and the willingness to engage in strategic behaviour economic experiments especially those conducted in the field have begun to paint a picture of economic agents in developing communities that is at variance with the traditional portrait we review this growing literature with an eye towards preference related experiments conducted in the field we also offer lessons on what development economists might learn from experiments we conclude by sharing our thoughts on how to conduct experiments in the field and then offer a few ideas for future research

economics health and health economics hyes healthy years equivalent versus qalys quality adjusted live year this paper responds to culyer and wagstaff s cw and buckingham s b arguments we refute their claim about the equivalence of hyes and qalys they fail to distinguish between choice under uncertainty and under certainty cw assume that all individuals have a specific form of utility function which yields their conclusion of equivalence b s arguments confuse the measurement technique and the utility theory from which it stems his argument about the normative superiority of the qaly construct is inconsistent with economic thinking the hye by being compatible with the principles of economics is superior to the qaly for economic evaluations of health care interventions

qalys and hyes under what conditions are they equivalent the paper examines what restrictions have to be imposed on the individual s preference structure for qalys and hyes to yield identical results it is shown that using qalys involves imposing three additional restrictions empirical evidence suggests that these restrictions cannot be expected to hold in all applications the main problem in using hyes appears to be practical an alternative index is proposed that may help to bridge the gap between qalys and hyes by combining to some extent the advantages of the two measures

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

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

cooperation among strangers with limited information about reputation abstract the amount of institutional intervention necessary to secure efficiency enhancing cooperation in markets and organizations in circumstances where interactions take place among essentially strangers depends critically on the amount of information informal reputation mechanisms need transmit models based on subgame perfection find that the information necessary to support cooperation is recursive in nature and thus information generating and processing requirements are quite demanding models that do not rely on subgame perfection on the other hand suggest that the information demands may be quite modest the experiment we present indicates that even without any reputation information there is a non negligible amount of cooperation that is however quite sensitive to the cooperation costs for high costs providing information about a partner s immediate past action increases cooperation recursive information about the partners previous partners reputation further promotes cooperation regardless of the cooperation costs

integration of multiple national markets for electricity the case of norway and sweden during the second part of the 1990s the nordic denmark finland norway and sweden countries have created a unique multinational market for electricity this paper aims to analyse the degree of integration of the different national markets that constitute the nordic electricity market in particular the norwegian and swedish wholesale and retail electricity markets are analysed the results suggest that the wholesale markets are well integrated thus prices differ significantly only during periods with unusually high or low supply of hydropower however the retail markets are not integrated to the same degree thus retail prices and trade margins differ significantly differences in the national electricity market legislation seem to be a key factor behind these differences

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

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

why do the free trade gain numbers differ so much the role of industrial organization in general equilibrium a small general equilibrium model calibrated approximately to match the canadian tradeable goods sector is used to examine the implications of a range of assumptions about pricing behaviour and entry barriers for the impact of free trade with the united states it turns out that only a model with an extreme combination of non competitive product market and free entry as well as unexploited scale economies can generate substantial gains from free trade other assumptions modelled include monopolistic competition market share pricing an economist s model and a mainstream industrial organization approach the predicted welfare gains range from zero to more than 7 per cent of gnp pourquoi est ce que les evaluations numeriques des gains derives de l accord de libre echange different tellement le role de l organisation industrielle dans l analyse d equilibre g6neral l auteur utilise un petit modele d equilibre general calibre pour approximer le secteur canadien des biens echangeables avec l exterieur dans son analyse des implications d un ensemble de postulats quant a la tarification et aux barrieres a l entree sur l impact du libre echange avec les etats unis il appert que seul un modele impliquant une combinaison extreme de marches de produit non concurrentiels et d entree libre ainsi que d economies d echelle non exploitees peut engendrer des gains substantiels comme resultat du libre echange on examine aussi d autres postulats concurrence monopolistique tarification pour maintenir une part du marche un modele a saveur economiste et 1 approche standard d organisation industrielle les gains de bien etre qu on predit selon les postulats de base couvrent un eventail de zero a 7 pour cent du pnb

revisiting long run relations in power markets with high res penetration abstract electricity generation from renewable energy resources res has become increasingly significant to reach eu and emissions reduction targets at the same time one of the main eu policy goals has been the creation of a common internal energy market for europe in this paper we focus on these two issues previously studied separately considering their possible interactions we first analyze the long run relationship between day ahead electricity prices and fuel prices natural gas and coal looking at two samples of years characterized by low and high res penetration then we explore the integration of eu markets we show that the electricity fuel nexus found over 2006 2008 changed dramatically over 2010 2014 for the majority of countries considered in particular the long run dependence of electricity from gas and coal prices is much lower in recent years furthermore our results confirm that the considered eu countries are becoming less integrated as res e increases our findings suggest that nationally implemented policies to support renewables are successful in increasing res penetration but they have lessened the linkage among eu markets then making integration more difficult to obtain

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

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

hye and tto what is the difference this paper demonstrates that the hye healthy years equivalent procedure not only has nothing more to offer than the tto time trade off method but that it introduces a systematic bias that is not present using tto diagrams are used to illustrate that the hye yields health status values not utilities as its creators suggest and to show that the hye and tto techniques are theoretically identical then empirical evidence concerning the standard gamble certainty equivalence disparity noted elsewhere in the literature is shown to indicate that hye responses are likely to contain systematic biases that will lead to hye estimates exceeding tto values

reassessing the integration of european electricity markets a fractional cointegration analysis this study extends existing literature on the assessment of electricity market integration in europe by developing and testing hypotheses on the convergence of electricity wholesale prices and adopting a time varying fractional cointegration analysis in addition the potential impacts of some special events that may affect system capacity new interconnection market coupling increase in share of intermittent generation on spot and forward markets are considered and evaluated daily spot prices from february 2000 to march 2013 of nine european electricity spot markets apx uk apx nl belpex epex fr epex de ipex nordpool omel and ote and month ahead prices in four markets french british german and dutch from november 2007 to december 2012 are investigated results show that unit root tests which are generally used in the literature to test market integration are inadequate for assessing electricity spot market convergence because spot prices are found to be fractionally integrated and mean reverting time series furthermore spot price behaviour and their association with different markets change over time reflecting changes in the eu electrical system one month ahead prices by contrast were found to have become more resilient to shocks and to follow more stable trends

modeling extreme dependence between european electricity markets electricity spot prices are characterized by sudden large movements followed a few days later by an equally large movement in the opposite direction these phenomena are called spikes upward movements and drops downward movements recent research has suggested that the dynamics of the electricity spot prices can be accurately described by hidden markov regime switching mrs models regime switch models separate the ordinary dependence and the extreme spike or drop dependence this is a crucial point since it is the extreme dependence that is of interest when computing risks we fit a large number of mrs models to six european electricity markets eex powernext apx power uk nl nord pool system sweden in order to analyze the nature of the prices the estimated regimes are then used to analyze the probability of an extreme event and the conditional probability for one market to experience an extreme event conditional that another market is experiencing the same event we find that the frequency of extreme events is positively related to the amount of renewable energy sources in the power system it can be argued that the dependence results in this paper give an indication of what future dependence for even more integrated markets with more renewable energy will be the integration of markets will lead to efficient sharing of reserves while the additional renewable energy will increase the need for reserves the results are of interest when computing financial risks e g var or expected shortfall when designing reserves but also as an indication of the degree of integration between markets

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

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

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

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

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

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

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

endogenous reputation formation under the shadow of the future recent research has shown that making people s decisions known to others may enhance cooperation in infinitely repeated prisoner s dilemma games with random matching this paper experimentally studies whether people can cooperate with each other by endogenously showing their identities and building cooperative reputations when there is an option to hide the identities our experiment shows that a non negligible fraction of subjects choose to conceal their identities and accordingly subjects fail to cooperate with each other in communities if hiding is cost free however almost all subjects disclose their identities and successfully achieve cooperation if a cost is charged for the act of hiding this finding has a broad methodological implication for the study of reputation mechanisms when infinitely repeated games are used in an experiment as people s behavior may be determined by their ability to hide identities

conditional cooperation and voluntary contributions to public goods we compare a partners condition where the same small group of subjects plays a repeated publi c good game to a strangers condition where subjects play this game in changing group formations subjects in the partners conditi on contribute from t he first period on significantly more to the publi c good than subjects in the strangers conditi on in the strangers conditi on contributions show a continual decay whil e in the partners conditi on contributions fluctuate on a high level until t hey decrease in the final periods we interpret subjects behavior in terms of conditional cooperation which is characterized by both future oriented and reactive behavior

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

in search of homo economicus behavioral experiments in 15 small scale societies we can summarize our results as follows first the canonical model is not supported in any society studied second there is considerably more behavioral variability across groups than had been found in previous cross cultural research and the canonical model fails in a wider variety of ways than in previous experiments third group level differences in economic organization and the degree of market integration explain a substantial portion of the behavioral variation across societies the higher the degree of market integration and the higher the payoffs to cooperation the greater the level of cooperation in experimental games fourth individual level economic and demographic variables do not explain behavior either within or across groups fifth behavior in the experiments is generally consistent with economic patterns of everyday life in these societies

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

play it again partner choice reputation building and learning from finitely repeated dilemma games often the fuller the reputational record people s actions generate the greater their incentive to earn a reputation for cooperation however inability to wipe clean one s past record might trap some agents who initially underappreciate reputation s value in a cycle of bad behaviour whereas a clean slate could have been followed by their reforming themselves in a laboratory experiment we investigate what subjects learn from playing a finitely repeated dilemma game with endogenous symmetric partner choice we find that with a high cooperation premium and good information investment in cooperative reputation grows following exogenous restarts although earlier end game behaviours are observed

qalys versus hyes this paper explores the claim that qalys are liable to misrepresent consumer preferences and hence lead to decision makers choosing options which are not those preferred by the public it also considers the claim that hyes do not suffer from this defect we argue that none of the examples offered to date demonstrate the alleged tendency of qalys to misrepresent preferences we also show that hyes are identical to qaly scores obtained from a time tradeoff experiment and therefore that the assumptions about preferences underlying hyes are just as restrictive as those underlying tto based qalys

social learning and voluntary cooperation among like minded people many people contribute to public goods but stop doing so once they experience free riding we test the hypothesis that groups whose members know that they are composed only of likeminded cooperators are able to maintain a higher cooperation level than the most cooperative randomly composed groups our experiments confirm this hypothesis we also predict that groups of like minded free riders do not cooperate yet we find a high level of strategic cooperation that eventually col lapses our results underscore the importance of group composition and social learning by heterogeneously motivated agents to understand the dynamics of cooperation and free riding

measuring market integration and estimating policy impacts on the swiss electricity market abstract we investigate market integration in central western european electricity markets with a focus on switzerland we propose a structural microeconometric approach to measuring the degree of market integration taking advantage of unilateral demand and supply shocks such as the generation from volatile renewable resources the unavailability of generation units and national holidays these exogenous events affect electricity prices in switzerland and allow estimating the level of market integration by disentangling their effects in congested and non congested situations exploiting information on congested and non congested situations in parametric instrumental variable estimation permits simulating hypothetical non congested swiss electricity prices in historically congested situations our approach allows considering the non linear nature of level shifts of congestion and disentangling it from the structurally different interplay of demand and supply in respective situations using data on hourly electricity prices and its determinants regarding switzerland and neighboring countries from 2015 and 2016 we find that an expansion of interconnector capacity at the german austrian swiss border could decrease swiss electricity prices substantially in a more attenuated way the same holds true for the french swiss and the italian swiss border for switzerland as a whole prices in congested situations are about 17 higher than hypothetical non congested prices

goods prices and exchange rates what have we learned import prices typically change by a smaller proportion than the exchange rate between the exporting and importing country recent research indicates that common currency relative prices for similar goods exported to different markets are highly correlated with exchange rates between those markets this evidence suggests that incomplete pass through is a consequence of third degree price discrimination while distance matters for market segmentation borders have independent effects the source of the border effect has not been clearly identified furthermore there is little evidence yet to suggest substantial market power is implied by the observed price discrimination

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

cooperation in the finitely repeated prisoner s dilemma more than half a century after the first experiment on the finitely repeated prisoner s dilemma evidence on whether cooperation decreases with experience as suggested by backward induction remains inconclusive this paper provides a meta analysis of prior experimental research and reports the results of a new experiment to elucidate how cooperation varies with the environment in this canonical game we describe forces that affect initial play formation of cooperation and unraveling breakdown of cooperation first contrary to the backward induction prediction the parameters of the repeated game have a significant effect on initial cooperation we identify how these parameters impact the value of cooperation as captured by the size of the basin of attraction of always defect to account for an important part of this effect second despite these initial differences the evolution of behavior is consistent with the unraveling logic of backward induction for all parameter combinations importantly despite the seemingly contradictory results across studies this paper establishes a systematic pattern of behavior subjects converge to use threshold strategies that conditionally cooperate until a threshold round and conditional on establishing cooperation the first defection round moves earlier with experience simulation results generated from a learning model estimated at the subject level provide insights into the long term dynamics and the forces that slow down the unraveling of cooperation

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

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

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

electricity wholesale market prices in europe convergence abstract this paper tests the hypothesis that the ongoing restructuring process in the european electricity sector has led to a common european market for electricity based on a principal component analysis pca of wholesale electricity prices in 2002 2006 we reject the assumption of full market integration for several pairs of countries the weaker hypothesis of bilateral convergence is accepted based on unit root tests kpss and adf and a convergence test based on filtered pairwise price relations this indicates that the efforts to develop a single european market for electricity were so far only partially successful we show that the daily auction prices of scarce cross border transmission capacities are insufficient to explain the persistence of international price differentials empirically our findings confirm the insufficiency of explicit capacity auctions as stated in the theoretical literature

rational cooperation in the finitely repeated prisoner s dilemma experimental evidence this paper presents experiments designed to examine the sequential equilibrium reputation hypothesis in the finitely repeated prisoner s dilemma the authors test the hypothesis by controlling the subjects ability to build reputations and by manipulating their beliefs that their opponent is irrational or altruistic the responses of subjects strongly support the sequential equilibrium prediction the results also suggest an important role for homemade altruism that is a natural tendency to cooperate that subjects bring to the experiment from the outside the authors find that there may be no difference between the beliefs that an opponent is altruistic and the actual chance it is so copyright 1993 by royal economic society

integration and shock transmissions across european electricity forward markets abstract new results are presented relating to the integration of the french german british dutch and spanish power markets at day ahead week ahead one month ahead and two month ahead lead times overall there is evidence of market integration increasing over time despite an underlying inefficiency in each market with respect to the forward and spot price convergence the spatial analysis on a financial dimension is undertaken using causality tests cointegration and impulse response techniques for both price levels and volatilities in general we find less influence of the size and proximity of neighbouring markets than other studies more integration at baseload than peak and surprisingly less integration in forwards than spot prices

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

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

presidential address institutions and culture how and why does distant political and economic history shape the functioning of current institutions this paper argues that individual values and convictions about the scope of application of norms of good conduct provide the missing link evidence from a variety of sources points to two main findings first individual values consistent with generalized as opposed to limited morality are widespread in societies that were ruled by non despotic political institutions in the distant past second well functioning institutions are often observed in countries or regions where individual values are consistent with generalized morality and under different identifying assumptions this suggests a causal effect from values to institutional outcomes the paper ends with a discussion of the implications for future research jel a10 d7 e00

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

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

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