generating real persistent effects of monetary shocks how much nominal rigidity do we really need abstract this paper attempts to assess whether money can generate persistent economic fluctuations in dynamic general equilibrium models of the business cycle we show that a small nominal friction in the goods market can make the response of output to monetary shocks large and persistent if it is amplified by real wage rigidity in the labor market we also argue that for plausible levels of real wage rigidity a small degree of nominal stickiness is sufficient for money to produce economic fluctuations as persistent as those observed in the data

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

real exchange rate volatility and economic openness theory and evidence this paper relates the volatility of the trade weighted effective real exchange rate to the degree of trade openness of an economy the theoretical part presents an intertemporal monetary model of a small open economy with nominal rigidities both monetary and aggregate supply shocks are shown to produce ceteris paribus smaller real exchange rate movements if the country is more open to foreign trade empirical evidence on a cross section of forty eight countries confirms this relationship differences in trade openness explain a large part of the cross country variation in the volatility of the effective real exchange rate

import penetration and the politics of trade protection abstract in this paper we reconsider a key empirical prediction generated by an important class of political economy models of trade policy namely that trade protection should be higher in sectors characterized by lower import penetration we call this the standard prediction the existing empirical evidence offers little support for this prediction in this paper we argue that the standard prediction depends critically on the assumptions that trade taxes are the only policy instruments and that the government has access to non distortionary taxation we analyze a model in which the government can use quotas and vers in addition to trade taxes and raising public funds may be costly under a simple sufficient condition our model predicts that the protection level increases with import penetration both in sectors that are protected with tariffs and in sectors that are protected with quantitative restrictions

is protection for sale evidence on the grossman helpman theory of endogenous protection grossman and helpman 1994 present a theory of endogenous protection by explicitly modeling government industry interactions for which mere black box models previously existed they obtain a ramsey pricing type solution to the provision of protection which emphasizes the role of inverse import penetration ratios and import elasticities on the lobbying side the model makes predictions about lobbying competition and lobbying spending according to deadweight costs from protection the model not only makes for richer theory in terms of rigor and elegance but its predictions are directly testable whether the grossman helman model stands up to real world data is investigated in this paper predictions from both the protection side and lobbying side are tested using cross sectional u s nontariff barrier data we also compare the second generation grossman helpman model with a more traditional specification our results call for serious consideration of this model in the political economy literature

real rigidities and the non neutrality of money rigidities in real prices are not sufficient to create rigidities in nominal prices and real effects of nominal shocks and by themselves small frictions in nominal adjustment such as costs of changing prices create only small non neutralities but this paper shows that substantial nominal rigidity can arise from a combination of real rigidities and small nominal frictions the paper shows the connection between real and nominal rigidity given the presence of nominal frictions both in general and for two specific sources of real rigidity one arising from goods market imperfections and the other from labour market imperfections

can appreciation be expansionary evidence from the euro area summarywe identify exogenous effects of shifts in effective exchange rates for euro area ea countries between 1999 and 2016 the identification strategy is based on an external instrument built on the assumption that movements in the euro nominal effective exchange rate are largely exogenous for individual ea countries once we control for ea aggregates we find that a real appreciation creates a trade off between expenditure switching contractionary and terms of trade expansionary effects with the latter prevailing in most countries we also find some heterogeneity in the way movements in the euro exchange rate are transmitted within the ea in particular between core and peripheral countries although differences are mostly not statistically significant

imperfect information and staggered price setting many keynesian macroeconomic models are based on the assumption that firms change prices at different times this paper presents an explanation for this staggered price setting the authors develop a model in which firms have imperfect knowledge of the current state of the economy and gain information by observing the prices set by others this gives each firm an incentive to set its price shortly after other firms set theirs staggering can be the equilibrium outcome in addition the information gains can make staggering socially optimal even though it increases aggregate fluctuations copyright 1988 by american economic association

foreign lobbies and us trade policy abstract in popular discussion much has been made of the susceptibility of government policies to lobbying by foreigners the general presumption being that this is harmful to the home economy however in a trade policy context this may not be the case if the policy outcome absent any foreign lobbying is characterized by welfare reducing trade barriers foreign lobbying may reduce such barriers and possibly raise welfare using a new data set on foreign political activity in the united states this paper investigates this question empirically tariffs and nontariff barriers are both found to be negatively related with foreign lobbying activity

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

financial market integration and macroeconomic volatility the process of financial market integration is modeled in an intertemporal general equilibrium framework as the elimination of trading frictions between financial markets in different countries goods markets are assumed to be imperfectly competitive and goods prices are subject to sluggish adjustment simulation experiments show that increasing financial market integration increases the volatility of a number of variables when shocks originate from the money market but decreases the volatility of most variables when shocks originate from real demand or supply copyright 1996 by the editors of the scandinavian journal of economics

commodity trade and international risk sharing how much do financial markets matter abstract this paper evaluates the social gains from international risk sharing in some simple general equilibrium models with output uncertainty a simulation model calibrated to selected moments of u s and japanese data estimates the incremental loss from a ban on international portfolio diversification to be on the order of 0 20 percent of output per year even the theoretical gains from asset trade may disappear under alternative sets of assumptions on preferences and technology the paper argues that the small magnitude of potential trade gains may help explain the apparently inconsistent findings of empirical studies on the degree of international capital mobility

accounting for inequality in india evidence from household expenditures summary we utilize household level consumption expenditure data from india to examine the evolution of inequality during 1983 2004 various measures of inequality show that inequality levels were relatively stable during 1983 93 but increased during 1993 2004 the increases in inequality have not precluded reductions in poverty however they are also more of an urban phenomenon and can be accounted for by increases in returns to education in the urban sector to a considerable extent especially among households that rely on income from education intensive services and or education intensive occupations some of the increases in the returns to education can be linked to economic liberalization undertaken in the 1990s

trade policy in majoritarian systems the case of the u s we provide a theory of trade policy determination that incorporates the protectionist bias inherent in majoritarian systems suggested by grossman and helpman 2005 the prediction that emerges is that in majoritarian systems the majority party favours industries located disproportionately in majority districts we test this prediction using u s data on tariffs congressional campaign contributions and industry location in districts represented by the majority party over the period 1989 97 we find evidence of a significant majority bias in trade policy the benefit to being represented by the majority party appears at least as large in magnitude as the benefit to lobbying on propose une theorie de la determination de la politique commerciale qui incorpore le tendence protectionniste inherent aux systemes electoraux a scrutin majoritaire selon grossman et helpman 2005 la prediction qui en ressort est que dans un tel systeme le parti de la majorite favorise les industries localisees de facon disproportionnee dans les circonscriptions detenues par la majorite on evalue cette prediction a l aide des donnees sur les tarifs douaniers aux etats unis sur les contributions aux campagnes electorales au congres et sur la localisation des industries dans les circonscriptions representees par le parti de la majorite pour la periode 1989 97 les resultats revelent un biais significatif dans la politique commerciale l avantage d etre represente par le parti de la majorite s avere au moins aussi important que l avantage du lobbying

protection for sale in a developing country democracy vs dictatorship for a genuine small open economy that has experienced both dictatorship and democracy we find support for the predictions of the grossman helpman 1994 protection for sale model in contrast to previous studies we use various protection measures including tariffs the direct measure of the theoretical model and perform both single year and panel regressions using turkish industry level data the government s weight on welfare is estimated to be much larger than that on contributions more importantly we find that this weight is generally higher for the democratic regime than for dictatorship

staggered price setting translog preferences and endogenous persistence abstract this paper generates persistent real effects of a monetary disturbance in the context of staggered price setters the model combines two related and reinforcing features a translog demand structure and a particular input output production structure these features offer a rationale why a firm when computing its own optimal contract price is influenced by the prices set in other overlapping contracts practically the two features interact in a positive manner and provide a way to generate significant endogenous persistence

international monetary policy coordination and competitive depreciation a reevaluation is there a need for international coordination of monetary policies within the current system of floating exchange rates in a recent paper obstfeld and rogoff 1995 argue that in an environment of sticky prices under floating exchange rates monetary policy shocks will generate positive welfare spillovers across countries this leads to the conclusion that international monetary policy coordination is unnecessary and may in fact be undesirable since it nurtures a bias towards high inflation our paper shows that these conclusions are dependent on the manner in which prices are set when firms engage in pricing to market ptm setting prices in the currency of the buyer monetary policy tends to have negative welfare spillovers this gives an incentive to engage in competitive depreciation in a noncooperative equilibrium world inflation will be higher the greater the importance of ptm with a high degree of ptm it follows that the case for international monetary policy coordination is restored if ptm is at an intermediate range however international monetary coordination may have no consequences at all

new directions for stochastic open economy models the paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages explicit solution of the wage setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare expected output and the expected terms of trade despite the potential interplay between imperfections due to sticky wages and monopoly the optimal monetary policy rule has a closed form solution to motivate our model we show that observed correlations between terms of trade and exchange rates are more consistent with our traditional assumptions about nominal rigidities than with a popular alternative based on local currency pricing 2000 elsevier science b v all rights reserved

protection for sale an empirical investigation comment do contributions levels matter for endogenous protection or is the existence of a lobby sufficient are lobbies net benefits from protection identical to their contribution levels or does the level of protection simply reflect contribution levels of supporters and opponents we estimate the influence driven grossman and helpman 1994 and the tariff function findlay and wellisz 1982 models within a unified theoretical framework to examine the contrasting implications derived from these two prominent tariff formation models we find strong evidence that protection is indeed for sale the important new result is however that not only the existence of lobbies matters but also the relative size of the sectoral pro and anti protection contributions using j tests to compare the power of the models directly we cannot reject the null of correct specification of the influence driven model and find evidence of some misspecification in the tariff function model

the role of consumption substitutability in the international transmission of monetary shocks abstract this paper develops a general framework to analyze the impact of monetary shocks in an open economy focusing on the role of the degree of substitutability between goods produced in different countries we extend the contributions by obstfeld and rogoff obstfeld m rogoff k 1995 exchange rate dynamics redux journal of political economy 103 624 659 and corsetti and pesenti corsetti g pesenti p 1997 welfare and macroeconomic interdependence nber working paper 6307 to show that the welfare impact differs across countries when the degree of substitutability between goods produced in different countries is different from the degree of substitutability between goods produced in the same country a shock that would be beneficial in a closed economy can have an adverse beggar thyself effect in the country where it takes place or an adverse beggar thy neighbor effect on its neighbor

economic growth inequality and poverty estimating the growth elasticity of poverty summary this paper uses a new data set of 126 intervals from 60 developing countries to analyze the growth elasticity of poverty that is how much does poverty decline in percentage terms with a given percentage rise in economic growth the data set is both broader in coverage and more selective in terms of quality controls than those used in the past the study finds that while economic growth does reduce poverty in developing countries the rate of poverty reduction depends very much on how economic growth is defined controlling for changes in income inequality when economic growth is measured by changes in survey mean income consumption the growth elasticity of poverty excluding eastern europe and central asia is 2 79 that is a 10 increase in the survey mean will reduce poverty 1 00 person day by 27 9 but when growth is measured by changes in gdp per capita the growth elasticity of poverty is a statistically insignificant 2 27 which is lower than has previously been estimated

reconsidering the empirical evidence on the grossman helpman model of endogenous protection the emergence of the grossman and helpman 1994 model of endogenous protection as the preeminent model in the political economy of trade literature has been significantly advanced by the finding that its predictions about the cross industry pattern of protection are broadly consistent with the data however in their empirical implementation of the grossman helpman model researchers have assumed the presence of multiple policy instruments and extraneous political factors we argue that incorporating these assumptions into the theory significantly changes its predictions about the cross industry pattern of protection jel classification f1 l emergence du modele de protection endogene de grossman helpman en tant que modele le plus important dans la litterature sur l economie politique du commerce international a ete confirmee de maniere significative quand on a decouvert que ses predictions quant au pattern de protection a travers les industries se trouvaient generalement confirmees par les donnees cependant dans leur verification empirique du modele de grossman helpman les chercheurs ont postule la presence de multiples instruments de politique publique et de certains facteurs politiques on suggere que l ajout de ces postulats change de maniere significative les predictions du modele quant au pattern de protection dans les divers secteurs

economic inequality in the arab region the paper uses harmonized household survey micro data to assess the levels and determinants of economic inequality in 12 arab countries it focuses on the sources of rural urban as well as metropolitan nonmetropolitan inequalities and applies the unconditional quantile regression decomposition technique to analyze the welfare gaps across the entire distribution the analysis finds moderate inequality levels with the gini coefficient for the distribution of household real per capita total expenditures ranging between 30 7 in libya and 45 in mauritania differences in households endowments such as demographic composition human capital and community characteristics appear as the main sources of the urban rural welfare gap there is inequality between metropolitan and non metropolitan regions in many countries mainly because of differences in returns to households characteristics and particularly returns to human capital

on the distributional effects of exchange rate fluctuations abstract how do exchange rate movements affect different sectors of an economy we address this question in a simple general equilibrium model stressing the different exposures of various sectors to foreign competition an aspect ignored in earlier contributions the impact of exchange rate shifts is highly heterogenous across sectors while a depreciation leads to a substantial competitiveness and welfare gain for agents with a high exposure to foreign competition agents facing mostly domestic competition are adversely affected

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

persistency in sticky price models abstract nominal rigidities imply that nominal shocks have an impact effect which may be propagated by standard mechanisms however the nominal adjustment process may in itself be a propagation mechanism causing persistent effects of nominal shocks this may be caused by inertia in nominal wage and price adjustment arising due to input output networks or multiperiod nominal contracting as captured in models with staggered price wage decisions it has recently been contested whether staggering can account for persistency of any quantitative importance this paper reviews the theory and empirical evidence on this issue and it is concluded that staggering may be a quantitative important propagation mechanism

welfare and macroeconomic interdependence we develop a baseline model of monetary and fiscal transmission in interdependent economies the welfare effects of expansionary policies are related to monopolistic supply in production and monopoly power of a country in trade an unanticipated exchange rate depreciation can be beggar thyself rather than beggar thy neighbor as gains in domestic output are offset by deteriorating terms of trade smaller and more open economies are more prone to suffer from inflationary shocks larger economies benefit from moderate demand led expansions but may be worse off if policy makers attempt to close the output gap fiscal shocks are generally beggar thy neighbor in the long run in the short run they raise domestic demand at given terms of trade thus reducing the welfare benefits from monetary expansions analytical tractability makes our model uniquely suitable as a starting point to approach the recent new open economy macroeconomic literature

trade wars and trade talks when governments meet in the international arena their actions reflect the political situations at home previous studies of trade relations have focused on governments that are immune from political pressures and that act as benevolent servants of the public interest here we introduce domestic politics into the analysis of international economic relations we study the interactions between national leaders who are concerned both with providing a high standard of living to the general electorate and collecting campaign contributions from special interest groups our analysis sheds light on the determinants of the structure of protection in non cooperative and cooperative policy equilibria

fiscal consolidation under fixed exchange rates abstract we present the fixed exchange rate version of the obstfeld and rogoff model and analyze the international transmission of fiscal policy shocks the welfare effects of an unanticipated contraction in government expenditure in the home country are shown to depend crucially on the way in which world money stock is set if home authorities alone are responsible for pegging the exchange rate a fiscal adjustment leads to a decrease in the real interest rate stimulates private consumption and limits the contraction in world output compared with a situation in which a cooperative scheme is implemented the model is then used to propose a new interpretation of recent events in the eu countries that have enacted restrictive fiscal policies while pegging their currencies to the dm

an unconditional quantile regression based decomposition of spatial welfare inequalities in ghana abstractghana has witnessed tremendous economic growth since the 1990s and attained the millennium development goals target of halving poverty this notwithstanding inequality in ghana increased over the same period suggesting growth benefits were not equitably distributed this study provides evidence on the determinants of household consumption expenditure and factors that explain rural urban welfare gaps between 1998 and 2013 the study employs an unconditional quantile regression and recently proposed decomposition technique based on re centred influence functions we find significant spatial differences in consumption expenditure across selected quantiles with rural urban inequalities driven largely by differences in returns to households endowments

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

international trade and the business cycle this paper develops a new empirical framework for analysing the dynamics of the trade balance in response to different types of macroeconomic shocks the model provides a synthetic perspective on the conditional correlations between the business cycle and the trade balance that are generated by different shocks and attempts to reconcile these results with unconditional correlations found in the data the results suggest that in the post bretton woods period nominal shocks have been an important determinant of the forecast error variance for fluctuations in the trade balance in g 7 countries the world economy has become increasingly integrated in recent years spurred by rapid expansions in trade and financial flows across national borders the rising share of international trade in world output suggests that trade could potentially have a greater influence on business cycle fluctuations both within and across countries hence understanding the factors driving fluctuations in international trade is important from a number of different perspectives including macroeconomic forecasting as well as for short run domestic policy considerations and international policy coordination the existing empirical literature on international aspects of business cycle fluctuations has followed a number of different approaches one strand of literature uses error component models to identify the sources of business cycle fluctuations and to assess the importance of common international shocks relative to country specific or industry specific shocks see stockman 1988 glick and rogoff 1995 another approach has been to document the role of international trade in the transmission of business cycles across countries as in

monopolistic competition and the effects of aggregate demand how important is monopolistic competition to an understanding of the effects of aggregate demand on output we ask the question at three levels can monopolistic competition by itself explain why aggregate demand movements affect output can it together with other imperfections generate effects of aggregate demand in a way that perfect competition cannot if so can it give an accurate account of the response of the economy to aggregate demand movements the answers are no yes and yes

consumption inequality between farm and nonfarm households in taiwan a decomposition analysis of differences in distribution consumption has been recognized as a more reliable indicator of household well being than income although a considerable body of literature has examined income inequality between farm and nonfarm households little is known about inequality in consumption this research aims to fill this knowledge gap by investigating consumption disparity between farm and nonfarm households using a nationally representative household survey from taiwan we apply an unconditional quantile regression based decomposition method to decompose the differences in the distribution of household expenditure between these farm and nonfarm households the results indicate that differences in the observed characteristics between these two types of households explain most of the consumption inequality moreover the difference in the education level of the farm operator household income and the degree of urbanization are particularly important jel classifications q10 q12

costly revenue raising and the case for favoring import competing industries abstract a standard finding in the political economy of trade policy literature is that we should expect export oriented industries to attract more assistance than import competing industries in reality however trade policy is heavily biased toward supporting import industries this paper shows how the costliness of raising revenue via taxation makes trade subsidies less desirable and trade taxes more desirable in a standard protection for sale framework the model is then estimated and its predictions tested using u s tariff data an empirical estimate of the costliness of revenue raising is also obtained

intermediate goods and business cycles implications for productivity and welfare this paper presents an aggregate demand driven model of business cycles that provides a new explanation for the procyclicality of productivity and simultaneously predicts large welfare losses from monetary nonneutrality the key features of the model are an input output production structure imperfect competition countercyclical markups and for some results state dependent price rigidity true technical efficiency is procyclical even though production takes place with constant returns without technology shocks or technological externalities the paper has observable implications that distinguish it empirically from related work these implications are generally supported by data from u s manufacturing industries copyright 1995 by american economic association

real exchange rates and the pattern of trade comparative dynamics for north and south abstract using a two country model of imperfect competition this paper examines cross sectional implications for the time series behavior of real exchange rates across different patterns of trade under intersectoral trade price setters display less interaction in their pricing decisions across national boundaries allowing for greater deviation and weaker mean reversion in relative prices conversely with intra industry trade greater price linkages between similar countries trading in similar goods generate lower pass through and less real exchange rate persistence the pattern of trade is shown to essentially alter the degree of domestic price stickiness which in turn affects the self correcting mechanism of an open economy

will wage setters ever stagger decisions models featuring the implications of long term contracts typically impose the pattern of negotiation and then develop the implications of this particular structure with no analysis of whether the structure is optimal or stable recent work however focuses on the choice of the timing of wage negotiations across sectors 1 in fethke and policano 1984 we develop a two sector model in which each sector is subject to both aggregate and relative disturbances the main result is that whenever the variability of relative disturbances exceeds the weighted variability of aggregate disturbances a uniformly staggered pattern of negotiation represents a symmetric noncooperative nash solution the twosector case has special properties first the benefit associated with staggered negotiation apparently depends on the existence of large negotiating sectors in the economy second symmetry of relative disturbances in the two sector case leads to the unusual equivalence of the noncooperative and the joint optimization solutions to the problem of determining the optimal negotiation pattern one natural question concerns whether the incentive to stagger negotiation dates will diminish as the number of sectors increases in this paper we develop the three sector case in detail and then generalize the analysis to any number of sectors the results indicate that the more significant are relative disturbances the larger is the number of sectors that will be supported by a stable nash equilibrium with uniformly staggered negotiation dates in an economy characterized by atomistic sectors the incentive to stagger negotiation dates disappears we also compare the joint optimization solution with the nash solution and find that when there are more than two sectors the requirement for uniform staggering to be optimal is more difficult to satisfy under joint optimization than under the nash strategy this di

how does a devaluation affect the current account abstract this paper explores how an exchange rate devaluation affects the current account in a sticky price inter temporal optimizing model the main issue addressed is how the features of international pricing affect the response of the current account when prices are all set in the producer s currencies the effect of a devaluation on the current account depends on the conventional marshall lerner conditions this is fundamentally an a temporal condition depending on the elasticity of substitution between home and foreign goods however when prices are all set in consumer s currencies the response of the current account depends upon the size of the inter temporal elasticity of substitution of consumption across time periods this represents an inter temporal condition when pricing to market is partial the effect of devaluation on the current account depends on the strength of the a temporal elasticity relative to the inter temporal elasticity

the equilibrium and optimal timing of price changes this paper studies the welfare properties of the equilibrium timing of price changes staggered price setting has the advantage that it permits rapid adjustment to firm specific shocks but the disadvantages that it causes unwanted fluctuations in relative prices and that by creating price level inertia it can increase aggregate fluctuations because each firm ignores its contribution to these problems staggering can be a stable equilibrium even if it is highly inefficient in addition there can be multiple equilibria in the timing of prices changes indeed whenever there is an inefficient staggered equilibrium there is also an efficient equilibrium with synchronized price setting

exchange rate management and macroeconomic policy a national perspective this paper reviews the literature on alternative exchange rate arrangements for a small economy it discusses exchange rate management for short run stabilization purposes and the choice of exchange rate regimes to foster policy discipline recent research has emphasized that the appropriate degree of exchange rate flexibility depends on the nature of disturbances exchange rate movements provide information about shocks and can serve as a basis for intervention rules empirically operational guidelines have not yet been provided floating rates are said to be desirable because they allow policy makers greater autonomy recent research has questioned the implicit assumption that autonomy is always useful rules that prevent discretionary policy may be preferable what role if any the exchange rate should play in such rules has not yet been resolved

tariff revenue and tariff caps we characterize the design of an optimal trade agreement when governments are privately informed about the value of tariff revenue we show that the problem of designing an optimal trade agreement in this setting can be represented as an optimal delegation problem when a money burning instrument is available in a specification with quadratic payoffs and a uniform distribution we find that the tariff cap and the probability of binding overhang are higher when the upper bound of the support distribution is higher and when the support distribution has greater width

what determines the nominal exchange rate some cross sectional evidence in this paper the determination of long run movements in nominal exchange rates across countries are examined the author models the long run movement in the nominal exchange rate as depending on 1 the long run inflation differential and 2 the long run change in the real exchange rate he argues that the former depends on country characteristics such as openness country size the level of outstanding government debt and central bank independence and the latter on the rate of economic growth and the terms of trade empirical support for both channels is provided suggesting the fruitfulness for the analysis of exchange rates of studying cross sectional cross country data

real exchange rates and macroeconomics evidence and theory since the early 1980s a large body of research has thrown doubt on the relevance of macroeconomic models for understanding exchange rates the authors argue that a balanced reading of recent literature in exchange rate economics gives a more optimistic assessment many studies have established the pertinence of long run purchasing power parity ppp and the explanatory power of macroeconomic fundamentals in real exchange rate fluctuations a reasonably strong case can be made for a traditional macroeocnomic interpretation of real exchange rates which emphasizes short run price stickiness but long run ppp but a central new ingredient in this interpretation is the presence of international commodity market segmentation and persistent deviations from the law of one price an example is given of a dynamic general equilibrium model that can reproduce some of the observed features of real exchange rate fluctuations

in which currency should exporters set their prices this paper studies the choice of price setting currency for an exporter faced with the choice of setting price in his own in the importers or a third currency under exchange rate uncertainty we establish that sufficient conditions on demand and cost functions for exchange rate pass through to be less than unity under certainty are also sufficient conditions for price setting in the importer s currency to yield the highest expected profit under exchange rate uncertainty under the same conditions on demand and cost functions setting price in the importer s currency maximizes expected utility when risk aversion and forward currency markets are introduced

a theory of trickle down growth and development this paper develops a model of growth and income inequalities in the presence of imperfect capital markets and it analyses the trickle down effect of capital accumulation moral hazard with limited wealth constraints on the part of the borrowers is the source of both capital market imperfections and the emergence of persistent income inequalities three main conclusions are obtained from this model first when the rate of capital accumulation is sufficiently high the economy converges to a unique invariant wealth distribution second even though the trickle down mechanism can lead to a unique steady state distribution under laissez faire there is room for government intervention in particular redistribution of wealth from rich lenders to poor and middle class borrowers improves the production efficiency of the economy both because it brings about greater equality of opportunity and also because it accelerates the trickle down process third the process of capital accumulation initially has the effect of widening inequalities but in later stages it reduces them in other words this model can generate a kuznets curve

inflation in open economies abstract this paper relates the time consistent inflation rate to the degree of trade openness of an economy the mechanism linking the welfare effects of monetary surprises and hence the incentives to inflate to openness does not rely on a large country terms of trade effect but rather is due to imperfect competition and nominal price rigidity in the non traded sector the empirical evidence supports the main predictions of the model 1997 elsevier science b v

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
