optimal incentive schemes with many agents the grossman hart principal agent model of moral hazard is extended to the multiple agent case to explore the use of relative performance in optimal incentive contracting under the assumption that the principal chooses incentive schemes to implement agent actions as nash equilibria necessary and sufficient conditions are derived for the optimality of independent contracts of rank order tournaments and for attainability of the first best in this context the relation of the principal s welfare to the correlation between the underlying randomness in outputs of different agents is also investigated finally some problems with the nash equilibrium implementation assumption are discussed in this paper we extend the grossman hart analysis of the principal agent problem to a multiple agent setting in this version of the problem a risk neutral principal is assumed to observe the output or a performance index for each risk averse agent the output of any agent depends on a privately observable action chosen by the agent and an exogenous random variable the realization of which is not observed either by the principal or by the agent before choosing its action we especially focus attention on the role of relative performance evaluation in optimal incentive contracts and the way this depends on properties of the underlying production technology and the joint distribution of the random variables affecting the outputs of different agents in section 2 of the paper we consider the principal s problem of finding an optimal incentive scheme and an action tuple for agents subject to the constraint that the latter be implemented as a nash equilibrium between agents by the chosen incentive scheme where agents must attain at least their reservation utilities a characterization of optimal incentive schemes is derived analogous to the grossman hart characterization for the single agent problem this characterization is then utilized to find sufficient and generically necessary conditions for a optimal contracts for any agent to be independent of the performance of other agents and b optimality of rank order tournaments where payments depend solely on ordinal comparisons of output across agents we then describe a necessary and sufficient condition for the principal to extract maximum advantage from relative performance clauses i e achieve the first best level of expected utility in the multiagent situation an implication of this result is that under fairly weak conditions perfect correlation in the underlying production uncertainties for different agents enables the principal to attain the first best if and only if sufficiently heavy penalties can be inflicted on agents we then enquire what happens in intermediate cases of non perfect correlation it turns out that while in general the principal s welfare is a continuous function of the correlation coefficient it is not always nondecreasing in the latter because the correlation coefficient is not a general measure of association between two random variables but rather a measure of linear association between them

estimating the foreclosure effect of exclusive dealing evidence from the entry of specialty beer producers this paper estimates an entry model to study the effect of exclusive dealing between anheuser busch and its distributors on rival brewers entry decisions and consumer surplus the entry model accounts for post entry demand conditions and strategic spillover effects i recover a brewer s fixed costs using a two step estimator and find spillover effects on brewers entry decisions i find that a brewer has higher fixed costs at locations where anheuser busch employ exclusive distributors but the effect is only statistically significant in certain local areas the estimates also show that a brewer is less likely to enter a location that is farther from its brewery has lower expected demand or is smaller in store size i implement counterfactual experiments to study the effect of banning exclusive contracts between anheuser busch and its distributors the results show that the welfare improvement associated with banning such contracts is very small

exchange rate pass through and the welfare effects of the euro this article explores the implications of the european single currency within a simple sticky price intertemporal model we focus on the question of how the euro may change the sensitivity of consumer prices in europe to exchangerate changes our central conjecture is that the acceptance of the euro will lead european prices to become more insulated from exchange rate volatility we find that this affects both the volatility and levels of macroeconomic aggregates in both the u s and europe we find that european welfare is enhanced and the u s shares in europe s good fortune

the politics of financial development evidence from trade liberalization incumbents in various industries have different incentives to promote or oppose financial development changes in the relative strength of promoter and opponent industries thus result in changes in the political equilibrium level of financial development we conduct an event study using a sample of 41 countries that liberalized trade during 1970 to 2000 and show that the strengthening of promoter relative to opponent industries resulting from liberalization is a good predictor of subsequent financial development the benefits of developing the financial system are insufficient for financial development and rents in particular hands appear to be necessary to achieve it copyright c 2008 by the american finance association

impact of cost shocks on consumer prices in vertically related markets the case of the french soft drink market we develop a structural econometric model of the vertical contracts between soft drink manufacturers and retailers to assess the impact of taxes or changes in production costs on consumer prices using individual data on food purchases from a representative survey of 19 000 french households in 2005 we estimate consumer demand using a random utility approach among a set of possible vertical relationships we select the model that best fits the data we evaluate the pass through rate of changes in input costs sugar or of taxes and show that the industry over shifts cost changes or excise taxes to the consumers this result challenges the belief that firms do not pass on the full extent of cost changes or excise taxes to consumers

exchange rate pass through in developing and emerging markets a survey of conceptual methodological and policy issues and selected empirical findings abstractglobal integration has increased the international linkages of financial markets for emerging market countries a key channel for the international transmission of inflation and economic cycles is from exchange rate movements to domestic prices known as exchange rate pass through erpt this article reviews the conceptual methodological and policy issues connected with erpt in emerging market and developing countries and critically surveys selected empirical studies a key contribution is to categorise and compare the heterogeneous methodologies used to extract erpt measures in the empirical literature single equation models and systems methods are contrasted frequent misspecifications that produce unreliable erpt estimates are highlighted the discerning policy maker needs to ascertain by which methods erpt measures were calculated the controls and restrictions applied and the time frame and stability of the estimates

the political economy of mass privatisation and imperfect taxation winners and loosers this article investigates the connection between the apparently uncorrelated issues of tax evasion and privatisation in a political economy framework we first consider how the political process given a country s level of development and income distribution will affect the efficiency of the tax system we then discuss the impact of the efficiency of the taxation system on the outcomes of privatisation we consider under which condition privatisation will proceed and who will be the political supporters as well as the main winners of the privatisation process moreover we investigate the impact of different forms of corruption both on the initial public support for privatisation as well as on its long term political sustainability

too many to fail evidence of regulatory forbearance when the banking sector is weak this paper studies bank failures in 21 emerging market countries in the 1990s by using a competing risk hazard model for bank survival we show that a government is less likely to take over or close a failing bank if the banking system is weak this too many to fail effect is robust to controlling for macroeconomic factors financial crises the too big to fail effect domestic financial development and concerns due to systemic risk and information spillovers the paper also shows that the too many to fail effect is stronger for larger banks and when there is a large government budget deficit

the effects of piracy on competition evidence from subscription tv abstract competition studies that focus on antitrust issues e g market definition market power are typically conducted in markets where all firms are assumed to operate legally competitors are tax abiding entities pay for all inputs used in their production process have paid the proper government licenses to do so etc we investigate competition issues in a market characterized by widespread piracy subscription tv in peru estimates suggest that 50 of subscription tv users in peru 30 in latin america use an illegal provider we make use of a unique dataset in which households provided crucial information regarding the il legality of their paid tv supplier using quantitative antitrust tools based on demand estimation techniques we study the impact that the presence of the informal sector has on competition our estimates suggest that the illegal operators constitute a close substitute for and henceforth significantly constrain the pricing power of legal operators this finding can have important antitrust implications the failure to account for piracy could lead to erroneous conclusions regarding market power measurement and the delineation of the relevant antitrust market this may be particularly important in several industries especially in the developing world where the leading operator may be cataloged as dominant only in the absence of illegal providers

a dynamic econometric model of thailand manufacturing energy demand the purpose of this article is to employ the dynamic translog framework to model inter factor and inter fuel energy demand for the thai manufacturing sector the denny et al 1981 and lynk 1989 framework which proposes a dynamic adjustment for capital stock is employed to motivate the estimated of factor demand and fuel share equations three factors energy labour and capital and five fuel types fuel oil diesel oil liquified petroleum gas lpg electricity and coal and lignite are examined regression diagnostics support the empirical specification numerous factor and fuel substitution possibilities are identified with some policy implications described

economic growth and interfactor interfuel substitution in korea this paper investigates the impact of increases in oil consumption and changes in wage rates on the interfactor interfuel substitution in korea a two stage translog cost function is estimated to incorporate the feedback effect between the interfactor and interfuel substitution empirical results show that the substitutability complementarity relationships among factors and fuels exhibit substantially different patterns before and after 1989

a structural time series approach to modelling multiple and resurgent meat scares in italy this paper exploits a structural time series approach to model the time pattern of multiple and resurgent food scares and their direct and cross product impacts on consumer response a structural time series almost ideal demand system sts aids is embedded in a vector error correction framework to allow for dynamic effects vec sts aids italian aggregate household data on meat demand is used to assess the time varying impact of a resurgent bse crisis 1996 and 2000 and the 1999 dioxin crisis the vec sts aids model monitors the short run impacts and performs satisfactorily in terms of residuals diagnostics overcoming the major problems encountered by the customary vector error correction approach

bank lending in transition economies bank privatization and tighter credit enforcement are believed indispensable to facilitate the eastern european transition process we analyze lending by value maximizing banks the only source of capital in the transition faced by non performing loans to the state owned sector we show that banks have a perverse incentive to fund former debtors although less efficient and more risky than private firms because they gain the potential repayment of previous debts this leads to a lower productivity of investment and a greater concentration of risk the expansion of more efficient private firms is delayed leading to a slower recovery and a greater risk of financial crisis

demand estimation in the presence of stochastic trend and seasonality the case of meat demand in the united kingdom if budget shares have stochastic trend or seasonality or both then demand equations based on the assumption of deterministic trend and deterministic seasonality will be mis specified we test this proposition by estimating a linearized almost ideal lai demand system for meat demand in the united kingdom using harvey s structural time series methodology we demonstrate that the model specification allowing for stochastic trend and deterministic seasonality performs best in terms of diagnostic tests and goodness of fit measures it is also shown that the model with stochastic trend is better at out of sample forecasting

privatization in eastern europe irreversibility and critical mass effects abstract this paper proposes a model to shed light on two important policy features of privatization in central and eastern europe the idea of a necessary critical mass of privatization on one hand and the great difficulties encountered in the actual privatization process on the other the model incorporates a positive externality related to the size of the private sector multiple equilibria may arise for political and economic reasons policies of free distribution are analysed with the model they may eliminate the danger of policy reversals due to excess unemployment but may at the same time increase the relative cost of restructuring leading in some cases to pareto inferior outcomes

price elasticities and demand side real rigidities in micro data and in macro models abstract high degrees of demand side real rigidities are able to generate the large monetary non neutrality found in aggregate data this paper provides micro based evidence on the key parameters governing this rigidity using european homescan data we find strong evidence for demand side real rigidity which is however significantly lower than that normally assumed in macro models in a menu cost model calibrated to our estimates we show that these estimates are associated with reasonable values for production side parameters but they are not able to generate the degree of monetary non neutrality observed in macro data

modelling the trend and seasonals within an aids model of the demand for alcoholic beverages in the united kingdom the argument that is put forward in this paper is that failure to represent stochastic trend and stochastic seasonality in an aids model leads to a misspecified and possibly structurally unstable model this proposition is verified by estimating an aids model of the demand for alcoholic beverages in the united kingdom three versions of the model are estimated and it is demonstrated that the version allowing for stochastic trend and stochastic seasonality performs better than the other two versions of the model in terms of the diagnostics tests and goodness of fit measures the best estimated model turns out to possess the properties of having common components and being homogenous further empirical testing reveals the presence of stochastic trends and cointegration between the budget shares of beer and wine the results clearly indicate that there has been a shift away from the consumption of beer towards wine copyright 2002 john wiley sons ltd

interfuel substitution a meta analysis interfuel substitutability has been of longstanding interest to the energy economics and policy community however no quantitative meta analysis has yet been carried out of this literature this paper fills this gap by analyzing a broad sample of studies of interfuel substitution in the industrial sector manufacturing industry or subindustries or macro economy of a variety of developed and developing economies publication bias is controlled for by including the primary study sample size in the meta regression results for the shadow elasticities of substitution between coal oil gas and electricity for forty six primary studies show that at the level of the industrial sector there are easy substitution possibilities between all the fuel pairs with the exception of gas electricity and coal electricity substitution possibilities seem more constrained at the macro level and less constrained in sub industries estimates also vary across countries publication bias does not seem to be present but model and data specification issues very significantly affect the estimates derived by each individual study estimates from cross section regressions are generally largest fixed effects panel estimates intermediate in magnitude and time series estimates are mostly much smaller econometric research suggests that the fixed effects estimates are likely the best among the existing studies though biased downwards

who bears the cost of a change in the exchange rate pass through accounting for the case of beer abstract nominal exchange rates are remarkably volatile they ordinarily appear disconnected from the fundamentals of the economies whose currencies they price these facts make up a classic puzzle about the international economy if prices do not respond fully to changes in the nominal exchange rate who bears the cost of such large and unpredictable changes foreign firms domestic firms or domestic consumers this study presents a new analysis of the sources of incomplete pass through and then uses this analysis to re examine its implications for social welfare i develop and estimate a structural model that analyzes the sources of local currency price stability for a particular industry the model enables counterfactual simulations that quantify the relative importance of firms local cost components and markup adjustments in the incomplete transmission of exchange rate shocks to prices and the effect of the exchange rate shock on domestic and foreign firms profits and on consumer surplus the model is applied to a panel dataset of one industry with retail and wholesale prices for upc level products i find that markup adjustments by manufacturers and the retailer explain roughly half of the incomplete transmission and local cost components account for the other half foreign manufacturers generally bear a greater cost or reap a greater benefit following an exchange rate induced marginal cost shock than do domestic consumers domestic manufacturers or the domestic retailer

inertial credit and opportunistic arrears in transition in a transition economy enterprise restructuring may exhibit a laffer curve response to tighter credit as a result of rational collective inertia in the presence of a rigid production structure unenforceable contracts and high adjustment costs a contraction in credit finance subtracts more liquidity than enterprises can generate internally because unrestructured firms are forced to extend trade credit to illiquid buyers an increase in their number increases the availability of forced supplier credit in turn increasing the attractiveness of inertial behavior as trade credit cannot be enforced a critical mass of trade and wage arrears causes pressure for a collective bailout thus validating inertial behavior even by reformable firms

divestiture requirements as a tool for competition policy a case from the swedish beer market we investigate the effect of divestitures on prices and welfare following the carlsberg pripps merger in the swedish beer market both difference in difference estimation and simulations using a random coefficients logit model suggest that divestitures are important for dampening price increases prices of divested brands fall by around 3 and the predicted price increase for carlsberg falls from 3 to 1 6 as a result of the divestitures to guide practice on divestitures we investigate the role of the recipient and the number and characteristics of the divested products by simulating post merger outcomes for all relevant cases we find that in this setting with large multiproduct firms the competition authority s most effective means to dampen adverse post merger outcomes are to aim for a small recipient firm and attain a large number of divested products enforcing larger divestitures in terms of market share and raising the average cross price elasticity between the merging parties divested and retained products strengthen the dampening effect further

measuring market power in the ready to eat cereal industry the ready to eat cereal industry is characterized by high concentration high price cost margins large advertising to sales ratios and numerous introductions of new products previous researchers have concluded that the ready to eat cereal industry is a classic example of an industry with nearly collusive pricing behavior and intense nonprice competition this paper empirically examines this conclusion in particular i estimate price cost margins but more importantly i am able empirically to separate these margins into three sources i that which is due to product differentiation ii that which is due to multi product firm pricing and iii that due to potential price collusion the results suggest that given the demand for different brands of cereal the first two effects explain most of the observed price cost margins i conclude that prices in the industry are consistent with noncollusive pricing behavior despite the high price cost margins leading firms are able to maintain a portfolio of differentiated products and influence the perceived product quality it is these two factors that lead to high price cost margins

variety pass through an examination of the ready to eat breakfast cereal market abstract we examine variety pass through effects that occur when multiproduct retailers adjust the length of their product lines in response to changes in wholesale prices studying variety pass through is essential to understanding how wholesale price changes transmit into retail prices when variety is endogenous using data from the ready to eat breakfast cereal category we find that retailers jointly adjust retail prices and the length of their product lines in response to changes in wholesale prices we show the importance of controlling for the endogeneity of retailers product line decisions when calculating price pass through rates

price transmission and local market power empirical evidence from the austrian gasoline market we analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics speed and asymmetry of price transmission using data for a large number of indiv

prices profits and pass through of costs along a supermarket supply chain bargaining and competition in this paper we present an empirical study of a supermarket supply chain to understand the determinants of prices and profits enjoyed by farmers processors and supermarkets we study the liquid milk market which has seen much controversy about both the distribution of rents and the mechanisms firms have used to influence the distribution we discuss insights from a series of interviews we conducted with executives and farmer representatives our interviews suggest a model in which the farmer s price is determined mainly by the sterling value of international commodity prices the retail price is determined by marginal costs and the intensity of supermarket competition and the wholesale price is determined in private bilateral negotiations between retailers and processors which are characterized by well informed agents and a high level of efficiency we present a simple theoretical model that captures these features and bring it to data on supply chain prices for the period 1994 2014 we find that over this period there has been great variation in the intensity of retail price competition and in the sterling value of international commodity markets which together result in large changes both to the overall surplus in the supply chain and to its distribution between farmers and the other firms after farmers have been paid the sterling value of international commodity prices the profit that remains to be split between processors and retailers mostly goes to supermarkets because of competition between processors

commodity price inflation retail pass through and market power abstract when commodity prices rise wholesalers and retailers of products derived from basic commodities respond by passing along at least a portion of the price increase to consumers in this paper we examine whether firms respond differently to positive commodity price shocks than to negative commodity price shocks that is whether commodity price volatility alters market power we exploit recent volatility in food commodity prices over the period 2007 2010 to investigate how commodity price shocks translate into market power in two different vertically structured food product industries potatoes and fluid milk for potatoes we find both wholesale and retail market power decreases increases during periods of rising falling commodity prices moreover price cost margins widen a substantially greater degree in response to negative shocks than margins narrow in response to positive shocks indicating that commodity price volatility increases market power for fluid milk we find that market power likewise declines during periods of rising commodity prices however market power does not significantly change during periods of falling commodity prices suggesting that commodity price volatility decreases market power

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

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

double marginalization and cost pass through weyl fabinger and cowan meet spengler and bresnahan reiss consider the classical double marginalization problem of single product successive monopolies we show that the ratio of the cost pass through at the final sale relative to that at the wholesale level is characterized by the curvature of inverse demand in the final market we also apply cowan s 2012 method which utilizes the idea of pass through in an analysis of third degree price discrimination to compare consumer surplus under vertical integration and separation

the political economy of transition the overriding importance of political constraints in the transition process has led to developments of the theory of the political economy of reform what are the main insights from that theory how does it reflect the transition reality what have we learned and what do we still need to learn the present article will attempt to answer those questions

a comparison between economic systems with an application to transition abstract this paper develops a general equilibrium theory of endogenous firm and class formation under non contractibility with heterogeneous individuals a collectivist economy a private ownership economy and a mixed economy are compared on the basis of identical economic fundamentals methodological symmetry each economic system generates specific inefficiencies so that none dominates the others in general the main trade off is between the welfare loss associated with risk taking in the private ownership economy and the informational problems in the collectivist economy we then use this framework to study the political economy of transition between economic systems and provide detailed welfare results

electricity demand of manufacturing sector in turkey a translog cost approach abstract this paper models factor demand for manufacturing sector in turkey we estimated a translog cost function with four factor consist of capital labor intermediate input and electricity over the 1980 2001 our objective taking in the consideration electricity as production input was twofold on the one hand to estimate the price elasticity of electricity demand in manufacturing sector and on the other hand to use cross price and morishima elasticities of substitution results for structural analysis regarding effects of electricity liberalization which initiated in 2001 empirical result shows that electricity demand is relatively price sensitive 0 85 our result in terms of electricity price is consistent with the previous studies while electricity labor and electricity capital inputs are complementary results indicate the existence of substitution possibilities between electricity and intermediate input this means that changes in electricity prices have impact on labor demand and investment demand these results have important implications for public policy

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

pass through in a concentrated industry empirical evidence and regulatory implications we estimate pass through with thirty years of data from a concentrated industry the empirical model accounts for oligopoly interactions yet facilitates estimation with aggregate price data robust statistical evidence supports that industry wide cost changes are more than completely transmitted downstream and that this industry pass through is largely unaected by competitive conditions the industry in question portland cement is a major focus of environmental and antitrust regulators we use our pass through estimates to i evaluate the welfare consequences of marketbased co2 regulation ii predict the magnitude and location of price eects due to a merger under review by antitrust authorities and iii corroborate the simulation based analysis of the epa regarding its impending regulation of local pollutants

czech privatisation 25 years later privatisation is still a hot political topic today and divides economists as well as politicians and the general public the paper aims to capture the czech privatisation in its historical economic and political contexts the first part explains the difference between transitional privatisation and standard privatisation the second part examines the interests in the privatisation process the third part discusses the privatisation methods used in the czech republic the fourth part offers an international comparison

antidumping investigations and the pass through of antidumping duties and exchange rates comment well in excess of 100 percent based on their understanding of the us antidumping calculation however the hypothesis is based on an incorrect understanding of the antidumping calculation under us law when corrected for this error the hypothesis would lead to a prediction of simple 100 percent pass through at most dumping refers to selling a product in an export market at less than its normal value a benchmark that is most commonly based on sales in the domestic market of the same product antidumping laws set tariffs to offset the amount of dumping the excess of normal value over export price in us practice a dumping complaint is brought on behalf of an industry against rival imports with the cases defined by product and by country a successful case results in the potential imposition of antidumping duties over and above any normal tariffs an unsuccessful case results in no duties being imposed american antidumping law and practice have the somewhat unusual characteristic that anti dumping duties are estimated and used to set duty deposits for a forward looking period in an initial investigation then are recalculated and actually assessed for the same period now back ward looking in a later review with some variation the later review is typically completed about two years after the initial investigation the review sets a new deposit rate and a second review determines the actual assessment rate retrospectively this can be repeated indefinitely the ini tial duty estimate resulting in a deposit rate allows companies to modify their pricing behavior so as to affect the actual dumping duties that are later assessed blonigen and haynes exploit this characteristic of the us administration of its antidump ing law to examine the effects of the imposition of antidumping duties on the pass through to us pricing the dumping investigation and resulting deposit rate provide information that the company can use in its subsequent sales in order to reduce or eliminate its dumping liability in the eventual review by comparing the antidumping deposit rates with eventual us pricing the degree of pass through of antidumping deposits can be estimated and the effects on exchange rate pass through of a potential antidumping dumping duty can be studied here i focus on the factual underpinnings that lead to blonigen and haynes s pricing model rather than the empirical results that model predicts that the method by which the us department of commerce usdoc calculates ad duties will lead to pass through of estimated antidump ing duties at twice the level of those estimated duties if companies wish to eliminate the eventual dumping duties by studying the outcomes of a series of ad cases concerning steel from canada they conclude that pass through of estimated duties exceeds 160 percent broadly consistent with

outsourcing and pass through a large share of international trade occurs through intra firm transactions we show that this common cross border organization of the firm has implications for the well documented incomplete transmission of shocks across such borders we present new evidence of an inverse relationship between a firm s outsourcing of inputs and its rate of exchange rate pass through we then develop a structural econometric model with final assemblers and upstream parts suppliers to quantify how firms organization of their activities across national borders affects their pass through behavior

empirical evidence on the role of non linear wholesale pricing and vertical restraints on cost pass through abstract how a cost shock is passed through to final consumer prices may relate to nominal price stickiness and rigidities the existence of nonadjustable cost components strategic markup adjustments or other contract terms along the supply distribution chain this paper presents a simple framework to assess the potential role of nonlinear pricing contracts and vertical restraints such as resale price maintenance or wholesale price discrimination in the supply chain in explaining the degree of pass through from upstream cost shocks in the ground coffee category to downstream retail prices we find that resale price maintenance increases pass through rate

inter fuel substitution technical change and the demand for energy in the uk economy a model for energy demand based on a translog cost function is formulated unlike previous studies technical progress is modelled by means of stochastic as opposed to deterministic trend components the model is estimated using quarterly uk data for four economic sectors and forecasts of the future level of demand are made

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

retailers and consumers the pass through of import price changes in this paper we estimate pass through rates of import price changes to retail prices across retailers and consumers for apparel purchases in germany for the period of 2000 07 we find that high price retailers do not pass through changes in the import price pass through rates for low price retailers are 53 per cent within three months consequently pass through rates for low income households are 58 per cent significantly larger than those for high income households we then present one possible explanation for these observations in a theoretical model with endogenous vertical product differentiation due to bundling an ex ante homogeneous import goods with services following an import price change retailers who sell a cheaper unbundled product change prices to a greater extent than retailers who sell a higher priced bundle of product and service

economies of scope in price setting a moment inequalities estimation abstract using weekly data on prices costs and units sold by a supermarket chain a moment inequalities approach is used to estimate a discrete choice dynamic model of a multiproduct firm facing menu costs this empirical methodology allows to estimate two types of fixed costs of price adjustment costs that are independent of the number of items that change prices and costs that are incurred at each item s price change i find that both types of menu costs exist and are substantial the total cost of changing prices is estimated to be bounded between 0 3 and 1 3 of revenues and between 17 and 65 of net margins the first type of fixed cost accounts for between 23 and 99 of this expense pointing to substantial economies of scope in price setting

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

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

modelling loss of resilience in agroecosystems rangelands in botswana economists have recently begun to consider the questions raised by the ecological concept of resilience a measure of the degree to which a system can be perturbed before it switches from one stability domain to another at a theoretical level it has been argued that the loss of resilience in an ecological economic system involves a change in its long run productive potential but no consideration has yet been given to the empirical investigation of this this paper discusses an econometric approach to the problem using the example of semi arid rangelands the long run productive potential of the system is regarded as an unobserved state variable change in which is irreversible or at least only slowly reversible it is estimated by applying the extended nonlinear kalman filter the paper illustrates the approach using data from botswana for the period 1965 1993 the maximum likelihood estimates of the parameters associated with the loss of resilience mechanism are non zero they indicate a small loss of resilience event at the end of the long drought in the 1980s however these parameters are very imprecisely estimated and are therefore statistically insignificant we find that the sensitivity of the system to exogenous shocks varies with fluctuations in both economic and non economic parameters contrary to what is usually thought to be the case the sensitivity of the system to exogenous shocks is only weakly affected by variations in offtake prices but is very strongly affected by variations in the cost of herd maintenance this suggests that offtake prices may be a weak tool for controlling the size of cattle stocks and preventing a loss of resilience on the other hand taxes on cattle stocks or grazing fees may be very effective

vertical relationships between manufacturers and retailers inference with limited data in this paper different models of vertical relationships between manufacturers and retailers in the supermarket industry are compared demand estimates are used to compute price cost margins for retailers and manufacturers under different supply models when wholesale prices are not observed the purpose is to identify the set of margins compatible with the margins obtained from estimates of cost and to select the model most consistent with the data among non nested competing models the models considered are 1 a simple linear pricing model 2 a vertically integrated model and 3 a variety of alternative strategic supply scenarios that allow for collusion non linear pricing and strategic behaviour with respect to private label products using data on yogurt sold in several stores in a large urban area of the u s the results imply that wholesale prices are close to marginal cost and that retailers have pricing power in the vertical chain this is consistent with non linear pricing by the manufacturers or high bargaining power of the retailers

speed of adjustment and self fulfilling failure of economic reform abstract an economic reform programme where inefficient public labour is laid off is considered the immediate effect is a lowering of wages and increased profitability in the private modern sector over time as capital accumulates in the modern sector wages and production increases big bang reform generates a sharp transitory drop in wages while gradual reform gives a more modest decline in the presence of a subsistence wage constraint popular resistance can cause the cancellation of big bang reform two arguments for gradualism can in that case be made first a more gradual reform requires a less abrupt drop in the wage and will therefore be feasible second the initial wage drop will be stronger if a cancellation of reform is expected and since cancellation is dependent on the severity of the initial wage drop multiple equilibria occurs the existence of multiple equilibria is dependent on the speed of reform sufficiently gradual programmes have a unique successful equilibrium

accounting for incomplete pass through recent theoretical work has suggested a number of potentially important factors in causing incomplete pass through of exchange rates to prices including markup adjustment local costs and barriers to price adjustment we empirically analyze the determinants of incomplete passthrough in the coee industry the observed pass through in this industry replicates key features of pass through documented in aggregate data prices respond sluggishly and incompletely to changes in costs we use microdata on sales and prices to uncover the role of markup adjustment local costs and barriers to price adjustment in determining incomplete pass through using a structural oligopoly model that nests all three potential factors the implied pricing model explains the main dynamic features of short and long run pass through local costs reduce long run pass through by a factor of 59 relative to a ces benchmark markup adjustment reduces pass through by an additional factor of 33 where the extent of markup adjustment depends on the estimated super elasticity of demand the estimated menu costs are small 0 23 of revenue and have a negligible eect on long run pass through but are quantitatively successful in explaining the delayed response of prices to costs we nd that delayed passthrough in the coee industry occurs almost entirely at the wholesale rather than the retail level

privatization policies in central and eastern europe privatization in central and eastern europe patrick bolton and gerard roland this paper assesses policies of mass privatization in germany czechoslovakia hungary and poland a central concern stemming from the analysis is that in view of the fiscal crisis facing economies in transition it is crucial for governments to try to maximize the proceeds from the sale of state assets because of the low initial level of private wealth it is important in this respect to let potential buyers borrow from the government or issue claims on future revenues obtained with the privatized assets to the government in order to pay for the privatized firms allowing for such non cash bids removes the government s incentive to delay privatization for fiscal reasons reduces its ability to squander immediately the proceeds from privatization and improves the decentralization of control by allowing less wealthy but more able bidders to buy the firms they are best suited to run

is energy cost an accurate indicator of natural resource quality abstract the use of energy cost as an indicator of natural resource quality is examined energy cost is the direct and indirect energy used to produce a unit of a resource commodity different approaches to the role of energy in the economy are discussed and it is demonstrated theoretically that energy cost can give false indications of changes in resource quality this is because energy cost is only an accurate indicator of resource quality if either energy is the single primary factor of production and the economy can be represented by an input output model or if there is substitutability between the factors of production then marginal products must be proportional to the factors embodied energy these conditions are tested empirically using data from the us agricultural sector the results show that there is substitutability and marginal products are not proportional to embodied energy however the strong neoclassical assumption of price taking profit maximization can be rejected at a 5 level of significance though not at the 3 5 level the generality of the empirical results may be restricted due to data limitations but the theoretical framework can be applied to other data sets other resources and even other indicators

popular attitudes toward free markets the soviet union and the united states compared random samples of the moscow and new york populations were compared in their attitudes towards free markets by administering identical telephone interviews in the two countries in may 1990 although the soviet respondents were somewhat less likely to accept exchange of money as a solution to personal problems and although their attitudes toward business were less warm the authors found that the soviet and american respondents were basically similar in some very important dimensions in their attitudes toward fairness income inequality and incentives and in their understanding of the working of markets copyright 1991 by american economic association

tax incidence with strategic firms in the soft drink market abstract because soft drink sd consumption is considered to be a contributor to the epidemic of obesity there is a growing interest in evaluating the impact on sd consumption of alternative tax policies in this paper we propose a methodology to evaluate the impact of taxation of a food market taking into account the strategic price response of both manufacturers and retailers we apply this methodology to the french sd market and simulate the impacts of ad valorem and excise taxes we find that firms behave differently when facing an ad valorem tax or an excise tax an excise tax is overshifted to consumer prices while an ad valorem tax is undershifted to consumer prices we find that an excise tax based on the sugar content of sd is the most effective at reducing sd consumption our results also indicate that ignoring strategic pricing by firms leads to misestimations of the impact of taxation by between 15 and 40 depending on the products and the tax implemented in the short term that is ignoring positive long term health effects a 9 cents l excise tax has a small negative welfare effect about 1 person year

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

a structural approach to explaining incomplete exchange rate pass through and pricing to market the continuing depreciation of the dollar against other major currencies coupled with concerns about the impact of china s exchangerate policy on domestic prices has spurred new interest in the exchange rate pass through literature a recent study by economists at the federal reserve board of governors see mario marazzi et al 2005 attracted wide attention by documenting a steady decline over the past decade in the pass through of exchange rates into us import prices this finding was later challenged by a study published by the federal reserve bank of new york hellerstein deirdre daly and christina marsh 2006 which demonstrated that the finding of such a decline depends crucially on the specification of the pass through regression and in particular the inclusion of commodity prices this exchange highlights the need to understand the structural determinants of exchange rate pass through not only because such understanding is important when trying to forecast future pass through patterns but also because it provides guidance regarding the specification of the appropriate reduced form regression and more generally measurement of pass through the increased availability of micro data on prices and quantities means that research uncovering these determinants is more promising than sources of international price stickiness

asymmetric substitutability between energy and capital evidence from the manufacturing sectors in 10 oecd countries abstract this paper investigates the substitutability between energy and capital in the manufacturing sectors of ten oecd countries since 1980 by applying a cost function approach that has been widely used to analyze industrial energy demand first we attempt to determine the source of the disagreement in the literature on the substitutability between energy and capital and reach a conclusion regarding the substitutability between energy and capital dividing energy and capital into sub inputs we analyze their substitutability the empirical results indicate that fuel tends to complement capital in most countries whereas electricity and capital are substitutes thus this study confirms that heterogeneity in energy sources is a primary component of the systematic variation in the substitutability between energy and capital second we examine asymmetric substitutability between energy and capital by estimating the morishima elasticity of substitution the estimates of the morishima elasticity of substitution demonstrate that the substitution of energy for capital has dominated the substitution of capital for energy this asymmetric substitutability is natural from the producer perspective because capital costs are much greater than energy costs in most countries these results imply that the adoption of energy saving technologies has not been induced in response to increased energy prices

a structural approach to identifying the sources of local currency price stability the inertia of the local currency prices of traded goods in the face of exchange rate changes is a well documented phenomenon in international economics this paper develops a structural model to identify the sources of this local currency price stability and applies it to micro data from the beer market the empirical procedure exploits manufacturers and retailers first order conditions in conjunction with detailed information on the frequency of price adjustments following exchange rate changes to quantify the relative importance of local non traded cost components markup adjustment by manufacturers and retailers and nominal price rigidities in the incomplete transmission of such changes to prices we find that on average approximately 60 of the incomplete exchange rate pass through is due to local non traded costs 8 to markup adjustment 30 to the existence of own brand price adjustment costs and 1 to the indirect strategic effect of such costs though these results vary considerably across individual brands according to their market shares

efficiencies brewed pricing and consolidation in the u s beer industry merger efficiencies provide the primary justification for why mergers of competitors may benefit consumers surprisingly there is little evidence that efficiencies can offset incentives to raise prices following mergers we estimate the effects of increased concentration and efficiencies on pricing by using panel scanner data and geographic variation in how the merger of the brewers miller and coors was expected to increase concentration and reduce costs all else equal the average predicted increase in concentration led to price increases of 2 but at the mean this was offset by a nearly equal and opposite efficiency effect

product differentiation and oligopoly in international markets the case of the u s automobile industry this paper develops and estimates a model of the u s automobile industry on the demand side a discrete choice model is adopted that is estimated using micro data from the consumer expenditure survey the estimation results are used in conjunction with population weights to derive aggregate demand on the supply side the automobile industry is modelled as an oligopoly with product differentiation equilibrium is characterized by the first order conditions of the profit maximizing firms the estimation results are used in counterfactual simulations to investigate two trade policy issues the effects of the ver and exchange rate pass through

limits to substitution and irreversibility in production and consumption a neoclassical interpretation of ecological economics abstract there are many methodological approaches within ecological economics one of the principal modes of analysis is a modified version of the standard neoclassical model this paper examines the parallels which emerge between the ideas of some ecological economists concerning production and the ideas of others concerning consumption when these ideas are interpreted in the neoclassical paradigm it is well known that ecological economics is characterized by arguments concerning limits to substitution between inputs energy natural capital etc vs manufactured capital labor etc in production and the implications these have for sustainability however various authors have also expressed concerns regarding limits to substitution in consumption either between environmental assets and other goods or between basic needs commodities and other goods though the specific reasons for non substitution are different in the production and consumption cases the underlying theme is that individual commodities and other inputs have unique physical or other properties which make them poor substitutes ideas about irreversibility in production and economic development are also prominent in ecological economics likewise many authors have argued for similar irreversibilities in consumption behavior in analogy to the term technological change i coin the term preferential change to describe these phenomena the linking themes in this case are that the economy environment system is evolutionary in character and that external effects intended and unintended consequences of actions or processes imposed on other parties or resources are all pervasive

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

capital accumulation unemployment and self fulfilling failure of economic reform abstract i consider fiscal reform and the consequences of expectations about reform cancellation the reform implies reduced taxes and the laying off of employees in an inefficient public sector if the resulting unemployment level declines sufficiently fast the reform is completed on the other hand if high unemployment levels prevail for too long the reform is cancelled cancellation affects the return on capital negatively hence expectations about cancellation will depress capital accumulation and increase the level of unemployment as a result multiple rational expectation equilibria may arise where expectations about cancellation prove self fulfilling the modelling framework is leontief technology in combination with ramsey optimization that exhibits simple and attractive algebra
