does exchange rate variability depress trade flows evidence from error correction models this paper examines the impact of exchange rate volatility on the trade flows of the g 7 countries in the context of a multivariate error correction model the error correction models do not show any sign of parameter instability the results indicate that the exchange rate volatility has a significant negative impact on the volume of exports in each of the g 7 countries assuming market participants are risk averse these results imply that exchange rate uncertainty causes them to reduce their activities change prices or shift sources of demand and supply in order to minimize their exposure to the effects of exchange rate volatility this in turn can change the distribution of output across many sectors in these countries it is quite possible that the surprisingly weak relationship between trade flows and exchange rate volatility reported in several previous studies are due to insufficient attention to the stochastic properties of the relevant time series copyright 1993 by mit press

u s bilateral trade flows and exchange risk during the floating period abstract this paper tests for real exchange rate risk effects on u s bilateral trade flows during the floating period using several new as well as previously used risk measures significant negative effects occur in five of six u s import flows and in two of six u s export flows with one export flow showing a significant positive effect these results are consistent with several previous findings for aggregate u s trade two risk measures using the forward exchange rate and assuming a time varying risk premium provide marginally more significant results than the others

time preference and international lending and borrowing in an overlapping generations model two economies represented by diamond type overlapping generations models and differing only in their pure rates of time preference are joined together capital formation balance of payments behavior and welfare are compared under autarky and openness with a positive natural rate of growth the low time preference country runs a current account surplus in the steady state but not necessarily outside it if preexisting capital is not shiftable between countries integration in the world economy makes the high time preference country worse off in the short run the ranking of stationary utility levels under autarky and openness is ambiguous

deficits and intergenerational welfare in open economies this paper deals with public debt in open economies extending diamond s overlapping generations model to a small open economy as well as an international equilibrium of two large economies it focuses on the intergenerational welfare redistributions caused by an increase in public debt triggered by a temporary government budget deficit and shows how these redistributions differ in open and closed economies the interplay between the deficits in the government budget and the current account is also analyzed it is shown how a single period with a government deficit can be followed by a sequence of periods with a deficit in the current account

are preferential trading arrangements trade liberalizing or protectionist preferential trade arrangements and especially free trade agreements have mushroomed in importance in the 1990s this has revived research on the effects of these arrangements both on the welfare of the member countries and those excluded and on the momentum for further liberalization of the open multilateral trading system this paper reviews the analyses and evidence to date as to these effects showing that analytically anything can happen and that to date there has been insufficient experience to draw conclusions from empirical evidence

international financial volatility and agricultural commodity trade a primer recent international financial crises east asia in 1997 russia in 1998 brazil in 1999 and the speed with which they have spread across countries and regions have called into question the very desirability of financial globalization that is the opening of balance of payments capital accounts in both developed and emerging economies since the mid 1980s 1 calls for a new global financial architecture have multiplied and new and old theoretical arguments for and against controlling capital flows as well as domestic financial markets especially banks have been put forward imf rodrik stiglitz there is little empirical evidence to support the debate over the potential effects of enhanced financial volatility at the sectoral level and especially on the agricultural economy has international financial volatility actually affected real sectoral performance and if so how after briefly reviewing literature in this area this paper introduces the methodology and preliminary results of an on going research project that addresses that question with reference to agricultural commodity trade the purpose of the paper is both to generate productive discussion and to motivate similar research in this

exchange rate uncertainty and agricultural trade using a sample of bilateral trade flows across ten developed countries between 1974 and 1995 this article explores the effect of exchange rate uncertainty on the growth of agricultural trade as compared to other sectors based on a gravity model that controls for other factors likely to determine bilateral trade the results show that real exchange rate uncertainty has had a significant negative effect on agricultural trade over this period moreover the negative impact of uncertainty on agricultural trade has been more significant compared to other sectors

the impacts of exchange rate volatility on vegetable trade flows trade flows of commodities are generally affected by the principles of comparative advantage in a free trade however trade flows might be enhanced or distorted not only by various government interventions but also by exchange rate fluctuations among others this study applies a commodity specific gravity model to selected vegetable trade flows among organization for economic co operation and development oecd countries to determine the effects of exchange rate uncertainty on the trade flows using the data from 1996 to 2002 the results show that while the exchange rate uncertainty significantly reduces trade in the majority of commodity flows there is evidence that both short and long term volatility have positive effect on trade flows of specific commodities this study also tests the regional preferential trade agreements such as the north american free trade agreement nafta the asia pacific economic cooperation apec and the eu and their different effects on commodities

exchange rate risk and u s agricultural trade flows this paper analyzes the effect of exchange rate risk on u s agricultural trade flows a model which incorporates exchange rate risk is applied to ten countries while exchange rate risk was not significant in the seven developed markets results indicate that the exchange rate variable adversely affected u s agricultural exports to the three developing countries used in the analysis these findings underscore the importance of exchange rate risk in developing countries trading behavior issues such as establishment of well developed financial and commodity markets in developing countries must be addressed in future research

the permanent income hypothesis estimation and testing by instrumental variables the permanent income hypothesis with rational expectation is restated estimated and tested by an instrumental variables technique on the postwar u s aggregate time series data the hypothesis is accepted on a consumption series which includes service flows from consumer durables if the consumption series is the one in the national income and product accounts the hypothesis is decisively rejected an explanation is suggested to reconcile the conflicting test results

one money one market the effect of common currencies on trade currency unions their dramatic effect on international trade a gravity model is used to assess the separate effects of exchange rate volatility and currency unions on international trade the panel data bilateral observations for five years during 1970 90 covering 186 countries includes 300 observations in which both countries use the same currency i find a large positive effect of a currency union on international trade and a small negative effect of exchange rate volatility even after controlling for a host of features including the endogenous nature of the exchange rate regime these effects statistically significant imply that two countries sharing the same currency trade three times as much as they would with different currencies currency unions like the european emu may thus lead to a large increase in international trade with all that that entails andrew rose

economic policy uncertainty and dollar pound exchange rate return volatility abstract the extent to which economic policy uncertainty epu amplifies exchange rate volatility has been an important research question for at least a decade previous research has investigated this relationship using monthly data concluding that epu imparts an effect on exchange rate volatility either contemporaneously or with a one month lag the use of monthly frequency however may not provide an accurate causal interpretation and may even compromise the accuracy of the estimates if the natural cycles of epu are shorter than a month to address this econometric concern i construct uncertainty measures at a daily frequency and estimate a garch model using daily usd british pound returns the evidence indicates that epu contributes to exchange rate volatility much more quickly than monthly data can detect using a regression technique for separating epu from non policy economic uncertainty i find that non policy market uncertainty increases volatility more than epu does

exchange rate uncertainty and foreign trade abstract this paper starts with reviewing the existing literature on exchange rate uncertainty and trade flows it then argues that potential costs of medium term uncertainty in exchange rates and competitiveness are likely to be much larger than that of exchange risk which has been the focus of the existing literature two measures of medium term exchange rate uncertainty are constructed one is a weighted function of the magnitude of past movements in nominal exchange rates and the current deviation of the exchange rate from equilibrium while the second depends on both the duration and the amplitude of misalignment from equilibrium exchange rates the empirical evidence reported in the paper suggests that when exchange rate uncertainty is defined over a medium term period it does affect adversely trade flows of the industrial countries under review with the notable exception of the united states

sectoral effects of exchange rate volatility on united states exports abstract we analyze the effects of real exchange rate volatility on the proportions of bilateral exports of nine categories of goods from the united states to seven major industrial countries using a fixed effect framework in six of the nine categories the volatility of the real exchange rate significantly affects the value of exports and in five of these categories the effect is positive these results are consistent with a model in which risk neutral firms increase supply of elastically demanded exports in response to an increase in the volatility of the real exchange rate

accumulation and growth in a two country model a simulation approach abstract this paper analyzes saving and capital accumulation in a two good growth model of two market economies in which economic agents optimize with perfect foresight the goal is to present a model in which short run dynamics and the steady state are soundly integrated we stress the importance of asset markets as the linkage that transmits disturbances both internationally and intertemporally while many components of the model described below can be found in the literature on optimal consumption investment and international growth models we provide a consistent synthesis our framework permits the analysis of structural adjustment in the global economy and the dynamic effects of a wide range of public policies

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

the impact of nafta on the united states we describe the main economic arguments posed for and against the north american free trade agreement nafta during the u s policy debate to evaluate these arguments we analyze recent trade data and survey post nafta studies we find that both the u s and mexico benefit from nafta with much larger relative benefits for mexico nafta also has had little effect on the u s labor market these results confirm the consensus opinion of economists at the time of the debate finally studies find that trade creation greatly exceeds trade diversion in the region under nafta especially in intermediate goods

industrial metabolism and the linkages between economics ethics and the environment abstract with industrialization the material flows in the world have grown enormously expanded geographically and become more open and complex traditionally the emissions have been strongly connected to earlier steps in the material flows extraction and raw materials intensive industry but during the last few decades the emissions from industrial pointsources have decreased radically in the western industrialized world the result of the industrial cleanup is a shift towards the latter steps of the societal material flows the relative importance of consumption emissions has increased as indicated in studies of the rhine basin important prerequisites for this development have been increasing environmental awareness and public opinion putting pressure on legislators authorities and companies and a dynamic industrial development with structural changes that have permitted investments in modern technology and emissions control despite the often radical emission reductions problems with acidification eutrophication diffusion of persistent organic chemicals and climate change still persist on a regional and global level during the last decade there has been an increasing emphasis on the international and global environmental problems the materials flow perspective has experienced a major breakthrough waste minimization recycling life cycle analysis and environmental auditing have become major themes in most european countries and have also started to influence industry the importance of the consumer and his attitudes and actions as well as the relationship between trade and environment are often emphasized in this context the industrial metabolism approach needs further development to be able to assist in meeting the modern challenges of environmental management to sum up flows of a few elements or products in a limited region is not sufficient it is necessary to develop the analysis of the context of the flows include industrial economic and geographical change in the analysis and more actively seek connection to political and industrial decision making and human behavior and attitudes the time geographical process landscape launched by torsten hagerstrand could be an important source of inspiration in this context

monopolistic competition and international trade reconsidering the evidence we test some propositions about international trade flows that are derived from models of monopolistic competition developed by elhanan helpman and paul krugman we investigate whether the volume of trade between oecd countries is consistent with the predictions of a model in which all trade is intraindustry trade in differentiated products we then repeat the test with non oecd countries we also investigate whether the share of intraindustry trade is consistent with a more general theoretical model in which some but not all trade is intraindustry trade our results lead us to question the apparent empirical success of these models

real exchange rate volatility and the us bilateral trade a var approach this paper uses var models to investigate the impact of real exchange rate volatility on u s bilateral imports from the united kingdom france germany japan and canada the var systems include u s and foreign macro variables and are estimated separately for each country the major results suggest that the effect of volatility on imports is weak although permanent shocks to volatility do have a negative impact on this measure of trade and those effects are relatively more important over the flexible rate period copyright 1989 by mit press

exchange rate uncertainty and us bilateral fresh fruit and fresh vegetable trade an application of the gravity model in order to analyse the effect of exchange rate uncertainty we apply an empirical gravity equation to two sets of us bilateral trade data fresh fruit over the period 1976 1999 for a panel of 26 countries and fresh vegetables over the period 1976 2006 for a panel of nine countries based on panel estimation methods and using both a moving sd measure and the peree and steinherr 1989 measure of exchange rate uncertainty the results show that us bilateral fresh fruit trade has been negatively affected by exchange rate uncertainty we also find some evidence that the exchange rate between the us dollar and the currencies of latin american trading partners accounts for most of the negative impact of exchange rate uncertainty on bilateral trade flows in fresh fruit in contrast when using panel estimation methods and both measures of exchange rate uncertainty we find no statistically significant evidence for any negative effect of exchange rate uncertainty on us bilateral fresh vegetable trade however

testing an optimizing model of the current account via the consumption function abstract as the intertemporal allocation of consumption lies at the heart of the optimizing approach to current account determination we assess the validity of this new view by testing an open economy consumption function this method avoids some interpretation difficulties in previous studies for the four countries examined we generally could not reject the overidentifying restrictions imposed by the specification of our model an extended version of the model does not find any clear evidence of substitution between private and public consumption all our results are robust to two different measures of the external asset stock

a game theory framework for cooperative management of refillable and disposable bottle lifecycles abstract firms engaged in industrial ecology hope to reduce environmental impacts and costs improve resource efficiency and create symbiotic relationships that reduce transaction costs and enhance information flow however current lca tools do not explain firms incentives to implement the principles of industrial ecology or how an individual or firm can affect the products and processes at other firms game theory on the other hand allows investigation of the willingness of producers and consumers to seek strategies that promote the common interest of the system while not harming their own interests this paper applies game theory to the lifecycle of bottle packaging and presents a framework for analysis of the choice between refillable and disposable bottles although refillable bottles may be more cost effective in the long run bottlers only have incentive to use refillable bottles when they are sure that consumer return rates will be reasonably high it has been found that consumers who keep or dispose of refillable bottles or respond to deposit refund return incentives by reducing their demand may drive costs up and encourage adoption of disposables a simple model is provided which finds the optimal bottler strategy as a function of the bottler s expectations for consumer cooperation

energy property and the industrial revolution narrative the industrial revolution ir story is the core of a mainstream economic history narrative of energy development relationships celebrating modern economic growth meg as the increase in per capita energy consumption in the last two centuries such a narrative emphasizes mineral technology and private property as the key elements of growth processes i will criticize the above narrative from a socio environmental history perspective for its inability to account for two crucial aspects of energy history 1 the role of social power as key determinant in how energy sources are used and to what ends 2 the socio ecological costs associated with the increase of energy consumption i will then review environmental history studies on energy industrialization and highlight possible future developments in the field the article makes a strong point for the need to look at energy transitions as social processes and to include the unequal distribution of environmental health and social costs of mineral energy into global history narratives

consumption permanent income and financial wealth in canada empirical evidence on the intertemporal approach to the current account the intertemporal approach to the current account is rejected as a complete explanation of the canadian current account federal government fiscal policy plays an important role in the determination of the current account a private sector agent that treats its holdings of net liabilities of the federal government as net wealth accumulates the sum of these liabilities and the net liabilities of non residents as part of an intertemporally optimal plan this result indicates both fiscal policy and intertemporal considerations are important determinants of current account behaviour consommation revenu permanent et richesse financiere au canada resultats empiriques d une approche au compte courant mettant l accent sur la dimension intertemporelle cet article montre que l approche mettant l accent sur la dimension intertemporelle ne produit pas une explication complte du comportement du compte courant canadien i1 semble que la politique fiscale du gouvernement federal joue un r6le important dans la conformation du compte courant un agent economique prive composite qui traite son portefeuille de dettes nettes du gouvernement federal comme richesse nette va accumuler la somme de ces dettes et des dettes nettes des non residents dans le cadre de son plan intertemporel optimal les resultats montrent que la politique fiscale et des considerations intertemporelles sont des elements determinants du comportement du compte courant

national borders and international trade evidence from the european union in this paper the impact of national borders on international trade within the european union is considered using a gravity model i find that averaged over all eu countries intranational trade is about ten times as high as international trade with an eu partner country of similar size and distance this relatively strong home bias suggests that even within the european union national borders still have a decisive impact on trade patterns jel classification f02 f14 f15 o52 ce memoire examine l impact des frontieres nationales sur le commerce international a l interieur de l union europeenne on montre que en moyenne pour tous les pays de l union europeenne le commerce intranational est a peu pres dix fois plus important que le commerce international avec un pays partenaire de l union europeenne de meme taille et a meme distance ce degre relativement important de preference nationale suggere que meme dans le cadre de l union europeenne les frontieres nationales ont encore un impact determinant sur les patterns de commerce

does exchange rate stability increase trade and welfare we develop a simple general equilibrium framework to study the effect of the exchange rate system on trade and welfare an important feature of the model is deviations from purchasing power parity caused by rigid price setting in buyers currency we find the following first exchange rate stability is not necessarily associated with more trade in a simple benchmark model with separable preferences and only monetary shocks trade is unaffected by the exchange rate system consistent with most evidence second both trade and welfare can be higher under either exchange rate system depending on preferences and on the monetary policy rules followed under each system finally in general there is no one to one relationship between the levels of trade and welfare across exchange rate systems

real interest rates home goods and optimal external borrowing the paper investigates the optimal time path of consumption and external borrowing in the dependent economy model the small country faces given world prices and a given world real interest rate the presence of a home goods sector implies that the relevant real interest rate appropriate to consumption decisions depends on the rate of change of the real price of home goods the paper shows how transitory disturbances in output or in the world real interest rate affect the time profile of consumption and the trade balance in particular it is shown that the presence of a home goods sector dampens the consumption effects of changes in the world interest rate

cointegration and the long run forecast of exchange rates abstract multivariate cointegration is used to generate the long run forecast of the dollar dm exchange rate it is shown that while the random walk model outperforms the monetary structural models in the short run the latter based on the error correction model outperform the former in the long run

theoretical contribution of industrial ecology to circular economy abstract circular economy ce currently represents a viable option for countries governments academia and society to transform the linear and semi circular materials and energy flows into circular flows and obtain better sustainable benefits in this sense industrial ecology ie with its tools can assist in the transition to ce therefore the main goal of this paper is to present the theoretical contribution of ie to ce the methodology used was based on bibliometric analysis in the international context with regard to the bibliometric analyses we have identified that the evolution of ce would not be possible without the existence of ie concepts and tools especially with tools such as industrial symbiosis is and eco industrial parks eips furthermore three levels of ie contribution to ce were identified such as conceptual technical and policy aspects finally new ce based researches from an ie perspective with bibliometric analysis and with co citation networks are possible including solid waste management and policies

dynamics of a floating exchange rate regime we study the full equilibrium dynamics of a two country world economy with a floating exchange rate traded and nontraded goods and explicit modeling of the use of money the resulting exchange rate equation depends on several details of the economic structure such as the supply structure and propensities to spend on various goods although real exchange rate movements have the usual association with the current account the ordinary exchange rate may appreciate or depreciate when there are deficits on current account even when the quantities of money do not change deviations from purchasing power parity and the fisher equation are shown to be the rule rather than the exception

a political economic model of u s bilateral trade a bstract interrelationships between economics and politics have long been recognized by scholars in the field of international relations this paper attempts to identify and quantify the factors aflecting bilateral trade flows between the united states and other countries by developing a gravity type model the model includes economic and political variables and is tested using data for sixty six u s trading partners results indicate that pure economic variables which reflect market forces are not the only factors affecting u s bilateral trade semi cconomic and international political factors are also important

a gravity model analysis of meat trade policies abstract the conventional gravity model is revised for a single commodity and applied to meat markets to determine factors affecting trade flows of meat this study demonstrates that the gravity model for a single agricultural commodity can be parameterized more effectively by using time series and cross section data rather than cross section data alone this study reveals that trade policies and subsidies used by exporting and importing countries livestock production capacity in countries and distances play an important role in determining trade flows of meat long term agreements achieve the highest performance toward enhancing international meat trade import quotas and the hoof and mouth disease on beef greatly impair meat trade
