fixing exchange rates a virtual quest for fundamentals abstract fixed exchange rates are less volatile than floating rates but the volatility of macroeconomic variables such as money and output does not change very much across exchange rate regimes this suggests that exchange rate models based only on macroeconomic fundamentals are unlikely to be very successful it also suggests that there is no clear tradeoff between reduced exchange rate volatility and macroeconomic stability

barriers to trade and the import vulnerability of us manufacturing industries while it is widely recognized that imports can discipline markets the strength of that disciplinary power surely varies across industries the determinants and extent of this interindustry variation in the disciplinary force for foreign trade flows is however relatively unexplored this article investigates the microeconomic determinants of changing import shares at the industry level for u s manufacturing industries based upon this investigation the authors are able to create an index that measures the relative vulnerability of the various manufacturing industries to foreign competition and test a number of hypotheses concerning the underlying causes of observed variations in import vulnerability copyright 1990 by blackwell publishing ltd

disentangling the migration trade nexus the pro trade effects of immigrants and emigrants in the presence of vertical and horizontal product differentiation this paper presents an exploration of the migration trade nexus taking the case of italy by crossing the two dimensions of migration immigration and emigration and the two dimensions of intra ind

horizontal and vertical intra industry trade an empirical test of the homogeneity hypothesis in this paper we study if and how country specific factors affect intra industry trade iit when heterogeneity among sectors is allowed for the paper is novel in that it is the first that addresses an issue raised by greenaway et al oxford bulletin of economics and statistics 1999 61 365 specifically employing data on a sample of oecd countries over a 10 year period 1997 1998 we build on and take forward a methodology pioneered by balassa and bauwens economic journal 1987 97 923 to study the determinants of horizontal and vertical iit using a multi industry approach in doing this we seek to avoid the more extreme measurement problems by allowing for heterogeneity among sectors when country specific factors are analysed and among countries when industry specific factors are considered the results are compared to those obtained using the traditional method that does not consider intersectoral heterogeneity we find that the two models yield statistically different results moreover the tests regarding the choice of model that is econometric tests designed to compare one model with another when different sets of explanatory variables are used confirm the relevance of intersectoral heterogeneity in affecting iit to the best of our knowledge a similar analysis has not yet appeared in the empirical literature on iit

trade demand spillovers and industrialization the emerging global middle class in perspective in this paper we investigate international demand spillovers brought about by a global middle class and their impact on trade patterns and industrialization we propose a multi industry and two country trade model featuring demand complementarities propagating increasing returns across industries and national boundaries we show how the international extent of demand spillovers depends upon asymmetries in domestic income distribution labor efficiency and labor force size that is on the global distribution of real income

an analysis of bilateral intra industry trade in the food processing sector this paper analyses determinants of intra industry trade in food processing for a 30 country sample over the period 1964 85 previous studies have tested the hypothesis that imperfect competition is a major determinant of intra industry trade iit in the durable goods manufacturing sectors this study is distinguised from the earlier studies of iit by the examination of the processed food sector sic 20 the use of a panel data set for 22 years and 30 countries available at the four digit sic level the use of purchasing power parity measures of gdp and the use of a weighted tobit model with fixed effects to account for the censored cross section time series nature of the date the results indicate that iti in food processing is a positive function of a country s gdp per capita and equality if gdp per capita between countries in addition it is also found that such trade is strongly influenced by distance between trading partners membership in customs unions and free trade blocs and also exchange r

the contribution of nonhomothetic preferences to trade abstract this paper estimates the economic significance of preference nonhomotheticity in international trade tastes are assumed to be identical but budget shares depend on per capita income a linear expenditure system is estimated for 34 countries over 11 commodity aggregates a counterfactual exercise is conducted to estimate the volume of trade caused by deviations from homotheticity the results indicate that nonhomothetic preferences may account for as much as one quarter of interindustry trade flows

international trade and developing countries an empirical investigation of the linder hypothesis this paper presents empirical evidence in support of the linder hypothesis for ve of the six east african developing countries studied here ethiopia kenya rwanda sudan and uganda this nding implies that these countries trade more intensively with others who have similar per capita income levels as predicted by linder the contributions of this research are three fold first new information is provided on the linder hypothesis by focusing on developing countries second this is one of very few analyses to capture both time series and cross section elements of the trade relationship by employing a panel data set third the empirical methodology used in the analysis corrects a major shortcoming in the existing literature by using a censored dependent variable in estimation

scale economies and the volume of trade in this paper we split the number of actual years of schooling into five components effective years repeated years skipped years inefficient routing years and dropout years estimation of earnings equations using these explanatory variables produces some interesting empirical and theoretical results the main empirical finding is that the concepts of actual and effective years of schooling that are usually used in the estimation of earnings equations are statistically inferior to our classification both concepts pro

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

intra industry trade in financial services abstract intra industry trade iit has been central to increasing the variety of products available to consumers unlike traditional trade theories the recent trade theories have placed an emphasis on the role of foreign direct investment fdi in generating trade and increasing the volume of iit this study is the first study of intra industry trade in banking services in which the key elements of the new trade theories of iit have been taken into account in measuring the determinants of iit in banking services the empirical results of the determinants of iit in banking services indicate that factor endowments average per capita income fdi in banking economies of scale in the banking sector trade intensity between the us and its partners and market openness make a positive contribution to the volume of iit in banking services furthermore the empirical results indicate that intra trade activities amongst the us multinational corporations reduce the level of iit in banking services for the us

price stability in open economies this paper studies the conditions under which price stability is the optimal policy in a two country open economy model with imperfect competition and price stickiness special conditions on the levels of country specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied these restrictions apply to both cooperative and non cooperative settings most importantly we show that cooperative and non cooperative solutions do not coincide despite market completeness and producer currency pricing in this framework our analysis suggests a role for international policy coordination

on the incidence of us tariffs this paper provides evidence on the incidence of tariffs on products of export interest to developing countries by investigating the relationship between per capita incomes of us trading partners and tariff rates it constitutes the first attempt to assess the incidence of tariffs imposed by the us on countries that span the entire range of per capita incomes average tariff rates are lower for the poorest and richest countries and higher for countries in the middle of the income distribution this finding is not consistent with the widely held view that tariffs used by industrial nations bear more heavily on products of export interest to poorer developing countries than on imports from industrial nations it is consistent with the tariff escalation pattern reported in earlier studies if advanced countries account for most products at the high end of the fabrication scale results show that poorest countries will find it difficult to escape tariffs by attaining higher levels of economic development

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

consumer expenditures and inequality an analysis based on decomposition inequality in u s consumption expenditures is examined using the lerman and yitzhaki covariance method for decomposing the gini coefficient by factors from the decomposition nonparametric estimates of elasticities with respect to total expenditures are derived using data from the 1987 u s consumer expenditure interview survey the overall gini based on total annual consumption expenditures is 0 33 consistent with parametric expenditure elasticities the gini expenditure elasticities for household operations apparel and services and entertainment are relatively high an implication of this result is that taxing such goods and services will increase the progressivity or reduce the regressivity of the tax system copyright 1993 by mit press

financial services global perspectives the purpose of this paper is to discuss the issues related to the deregulation of the financial services sector and the role of multilateral negotiations which has opened up opportunities for the expansion of international financial services the paper analyses various categories of international financial services and highlights those factors that contribute to an increase in the competitiveness of financial institutions in their attempt to increase the supply of international financial services the paper also analyses the complementary role of fdi and trade in international financial services and discusses some of the benefits of fdi in financial services that have led to a more efficient and more competitive financial services industry in the host countries

how product innovation in the north may immiserize the south a new look at the ricardian model with a continuum of goods abstract the paper proposes a theoretical model investigating the welfare consequences of technological shocks in a ricardian framework a la dornbush fisher and samuelson 1977 contrary to the existing literature the model incorporates a nonhomothetic demand function whose price and income elasticities are endogenously determined by technology nonhomothetic preferences are modeled as the result of the hierarchical consumption of luxury and necessity goods the nature of technical progress determines the consumption pattern and notably the magnitude of the substitution effect between necessities and luxuries the model is applied to the case of trade between two economies with different development levels it is shown in particular that the developing country can suffer a fall in utility as a result of technical progress in the developed country biased towards luxury goods this configuration depends on the size of the development gap and reflects the fact that southern goods are less attractive the higher the range of goods consumed this result suggests that there is an optimal level of development gap to avoid ldcs being harmed by technical progress in the north

estimating the armington elasticity the importance of study design and publication bias abstract a key parameter in international economics is the elasticity of substitution between domestic and foreign goods also called the armington elasticity yet estimates vary widely we collect 3524 reported estimates of the elasticity construct 32 variables that reflect the context in which researchers obtain their estimates and examine what drives the heterogeneity in the results to account for model uncertainty we employ bayesian and frequentist model averaging to correct for publication bias we use newly developed non linear techniques our main results are threefold first there is publication bias against small and statistically insignificant elasticities second differences in results are best explained by differences in data aggregation frequency size and dimension third the elasticity implied by the literature after accounting for both publication bias and study quality lies in the range 2 5 5 1 with a median of 3 8

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

regulation of international trade in the united states the tokyo round a model based on the economic theory of regulation is used to explain the interindustry pattern of tariff protection that emerged from the tokyo round although tariff reductions were modest and were conducted in large part using a harmonization tariff cutting formula evidence reported here suggests that domestic pressure groups were able to exercise influence over post tokyo round tariff levels results of this analysis provide support for the marvel ray tariff formation model copyright 1987 by the university of chicago

sticky prices as coordination failure this paper links the coordination failure and menu cost approaches to the microeconomic foundations of keynesian macroeconomics if a firm s desired price is increasing in others prices then the gain from price adjustment after a nominal shock is greater if others adjust this strategic complementarity leads to multiple equilibria in the degree of rigidity welfare may be much higher in the equilibria with less rigidity thus nominal rigidity arises from a failure to coordinate price changes jel e12 e30 keynesian macroeconomics waned in the 1970 s because economists grew disenchanted with its weak microeconomic foundations the central difficulty was that keynesian models were based on ad hoc rigidities in nominal wages and prices the 1980 s produced two approaches to reviving keynesian theory the menu cost literature n gregory mankiw 1985 george akerlof and janet yellen 1985 seeks to provide rigorous explanations for nominal rigidities these papers argue that small frictions in price setting are enough to produce large nominal rigidities in contrast the coordination failure literature russell cooper and andrew john 1988 abandons nominal rigidities and seeks alternative foundations for keynesian models the central idea is that many economic activities such as production e g john bryant 1983 trade e g peter diamond 1982 and investment e g nobuhiro kiyotaki 1988 exhibit synergism or strategic complementarity one agent s optimal level of activity depends positively on others activity strategic complementarity can lead to multiple equilibria with high activity equilibria superior to low activity equilibria thus an economy may be stuck in an underemployment equilibrium even though a superior equilibrium exists models with nominal rigidities and models with coordination failures are often presented as competing paradigms 1 this paper shows that this view is incorrect we take a step toward unifying the foundations of keynesian economics by showing that the two sets of ideas are highly complementary nominal rigidity arises from a failure to coordinate price changes this failure has the essential features of coordination failures in previous models flexibility in one firm s price increases the incentives for other firms to make their prices flexible this strategic complementarity leads to multiple equilibria in the degree of nominal rigidity equilibria with less rigidity more active price adjustment are often pareto superior to equilibria with more rigidity these results contribute to our understanding both of coordination failure and of nominal rigidity the range of keynesian phenomena explained by coordination failures is greatly expanded previous coordination failure models contain only real variables and thus ascribe no role to monetary policy or other determinants of nominal spending our results suggest that coordination failure is at the root of inefficient nonneutralities of money theories of nominal rigidities gain new empirical and policy im

should the exchange rate be a shock absorber this paper examines the welfare case for the exchange rate as a shock absorber cushioning an economy in face of shocks to world demand for its good we provide an example in which although the exchange rate acts perfectly as a shock absorber stabilizing output around the natural rate and eliminating the impact of nominal rigidities it may in fact be better to prevent the exchange rate from adjusting at all the explanation for this is that with incomplete international financial markets the natural rate is inefficient it does not respond enough to demand shocks while fixing the exchange rate increases the volatility of consumption the pro cyclical nature of monetary policy under a fixed exchange rate allows for a more efficient composition of consumption between home and foreign goods furthermore for the shocks examined a welfare maximizing monetary rule always dampens exchange rate volatility relative to that of a free float and in some cases may imply a fixed exchange rate d 2004 elsevier b v all rigths reserved

a theoretical explanation of some stylized facts of economic growth this paper presents a three good two country general equilibrium model that is consistent with several stylized facts of economic growth the three goods are manufactures agriculture and services manufactures are subject to economies of scale the model predicts that services a nontraded good must be more expensive in the country with higher per capita income it also shows that as per capita income increases we should expect the productivity in commodities relative to services to rise the model is able to generate many other stylized facts of economic growth

inequality and trade we incorporate demand side considerations in trade in a systematic but straightforward way we do so by focusing on the role of inequality in the determination of trade flows and patterns with nonhomothetic preferences when countries are similar in all respects but asset inequality we find that trade is driven by specialization in consumption n ot production these assumptions allow us to generate some interesting international spillover effects of redistributive policies we also look at the effects of combining inequality and endowment differences on trade flows and see that this has implications for the mystery of the missing trade we then study a model of monopolistic competition and find a novel vshaped relationship between the ratio of inter industry to intra industry trade and a country s inequality finally we look at how international differences in factor endowments affect this relationship between the ratio of inter to intra industry trade and inequality our theory formalizes as well as modifies linder s conjecture about the relationship between intraindustry trade and the extent of similarity between trading partners

intraindustry trade sources and effects on protection this paper provides an empirical analysis of the determinants of intraindustry trade we demonstrate that two way trade flows occur where conditions are favorable to international specialization consistent with the stigler williamson analysis of the division of labor the results are inconsistent with the prevailing product differentiationcum scale economies model of intraindustry trade in addition we show that intraindustry trade has a significant impact on protectionist pressures exports of closely related products have the effect of mitigating the tariff raising effects that imports would otherwise exert

exchange rate policy and endogenous price flexibility most theoretical analysis of exible vs flxed exchange rates takes the degree of nominal rigidity to be independent of the exchange rate regime choice itself but informal policy discussion often suggests that a credible exchange rate peg may increase internal price exibility this paper explores the relationship between exchange rate policy and price exibility in a model where price exibility itself is an endogenous choice of proflt maximizing flrms a flxed exchange rate can afiect the optimal degree of price exibility by altering the volatility of nominal demand facing price setting flrms we flnd that a unilateral peg such as a currency board adopted by a single country will increase internal price exibility perhaps by a large amount on the other hand when an exchange rate peg is supported by bilateral participation of all monetary authorities such as in a monetary union price exibility may actually be less than under freely oating exchange rates quantitatively we flnd that the endogenous increase in price exibility following a unilateral peg might be big enough that output volatility is no greater than it would be under a oating exchange rate regime

global implications of self oriented national monetary rules author s obstfeld maurice rogoff kenneth abstract it is well known that if international linkages are relatively small the potential gains to international monetary policy coordination are typically quite limited but what if goods and financial markets are tightly linked is it then problematic if countries unilaterally design their institutions for monetary stabilization are the stabilization gains from having separate currencies largely squandered in the absence of effective international monetary coordination we argue that under plausible assumptions the answer is no unless risk aversion is very high lack of coordination in rule setting is a second order problem compared to the overall gains from monetary policy stabilization

vertical and horizontal intra industry trade a cross industry analysis for the united kingdom a large theoretical literature has emerged directed at explaining the presence of intra industry trade iit one of the distinctions which comes out of these models is that between horizontal iit where goods are differentiated by attributes and vertical iit where goods are differentiated by quality in this paper horizontal and vertical iit in u k trade are disentangled using a unit value dispersion criterion and a range of industry characteristics the paper not only points up the relative importance of vertical and horizontal iit in the united kingdom it also demonstrates how a failure to separate them out can impact on the interpretation of empirical results copyright 1995 by royal economic society

terms of trade and exchange rate regimes in developing countries abstract since friedman essays in positive economics university of chicago press chicago 1953 157 203 an advantage often attributed to flexible exchange rate regimes over fixed regimes is their ability to insulate more effectively the economy against real shocks i use a post bretton woods sample 1973 96 of 75 developing countries to assess whether the responses of real gdp real exchange rates and prices to terms of trade shocks differ systematically across exchange rate regimes i find that responses are significantly different across regimes in a way that supports friedman s hypothesis the paper also examines the importance of terms of trade shocks in explaining the overall variance of output and prices in developing countries

social optimal household food waste taxes and government incentives in 2010 21 of the total food available for consumption in the united states was wasted at the household level in response to this waste a number of counties and u s localities have instituted policies disposal taxes directed toward reducing this waste however currently there is no federal food waste disposal tax the aim of this paper is to establish a theoretical foundation for household food waste and based on this theory to determine the social optimal food waste disposal tax along with a government incentive the theory unravels the interrelation between social food insecurity and external environmental costs which is not generally considered by households when they waste food a social optimal disposal tax and government incentive involve pigovian mechanisms and governmental expenditures for a zero level of food waste the social optimal disposable tax and government incentive approach infinity

trade barriers multinational involvement and intra industry trade panel data evidence from india the article analyses the effects of trade barriers and multinationals on the intensity of intra industry trade iit in a panel of indian manufacturing industries from 1988 to 1999 we find that the intensity of iit increases with the reduction of trade barriers this is expected as greater competition from imports leads individual plants in the domestic industry to specialize in the manufacturing of unique varieties the analysis suggests that horizontal market seeking multinational activities in the domestic industries exert a negative influence on iit this is consistent with the view that horizontal multinationals displace exports to the host country at the same time our results indicate that iit will be stimulated to the extent that the entry of multinationals induces intra industry specialization we also analyse the role of product differentiation and plant level scale economies in determining iit

commercial policy and intra industry trade abstract this paper constructs a model of intra industry trade within a multi product industry whose output range is limited to that obtainable from a particular type of capital intra industry trade is a natural outcome in this structure without requiring increasing returns to scale or imperfectly competitive markets and with its pattern determined along traditional relative factor abundance lines the volume of this trade will vary inversely with the level of trade restrictions as observed empirically other policies are then considered for their influence on the range rather than the level of domestic production since the former is the more likely policy objective under these circumstances

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

the political economy of administered protection trade restrictions are hardly ever voted directly by congress though the threat of direct congressional action is frequently present pressure for protection is usually applied through the major instruments for the administrative regulation of imports the antidumping and countervailing duty procedures and the escape clause mechanism in this paper we will examine these instruments for the administrative regulation of imports the form of the paper is not novel a theory of how these mechanisms work is developed then operational implications of this theory are deduced and tested over the record of countervailing duty antidumping and escape clause cases decided from 1975 through 1979 this is the period over which the trade act of 1974 was in force because the nature of these mechanisms is relatively unfamiliar a relatively large amount of institutional information is provided

indirect measures of trade costs limitations and caveats abstract trade barriers which include transportation costs tariffs language barriers and bureaucratic red tape play a key role in the determination of trade flows because direct measures are only available for a few components researchers have developed so called indirect measures of trade costs which estimate bilateral trade integration from cross sectional variation in observed trade flows the paper explores the theoretical and empirical determinants of these indirect measures of trade costs the results suggest that while they do capture variation in trade barriers the indirect measures may also reflect variation in other factors such as differences in tastes and production costs

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

the economics of special interest politics the case of the tariff this paper investigates the interaction of politicians and special interest lobbies the goal is to model the equilibrium levels of redistributive policies such as taxes subsidies tariffs and regulatory decisions the model is applied throughout to the setting of tariffs by contributing to political campaigns special interest lobbies generate economic returns higher tariffs generate revenue for import competing industries through higher product prices higher milk support prices raise dairy farm income and so forth the lobby invests to maximize these net economic returns in evaluating their chances of election politicians weigh the favorable effects of special interest money against the unfavorable association with the lobby and the social cost of the redistributive policy section i explores the lobby s problem it describes a formalization of mancur olson s discussion of the voluntary provision of public goods and optimal contributions by lobbies to political campaigns section ii describes determination of the equilibrium tariff positions of each politician in a political campaign

explaining armington what determines substitutability between home and foreign goods for decades trade economists have modeled imperfect substitution between home and foreign goods in consumption often called the armington assumption with little analysis of what explains the wide variation in these substitution elasticities across sectors using a varying coefficients model the authors estimate armington elasticities between u s domestic and foreign goods across over one hundred industrial sectors from 1980 to 1988 and examine the role of product industry political and home bias factors as determinants they find strong support that the presence of foreign owned affiliates affects armington elasticities in important ways and some support that entry barriers and union presence have an effect

the kennedy round evidence on the regulation of international trade in the united states the purpose of this paper is to analyze and provide empirical evidence regarding the regulation of international trade flows our goal is to provide an explanation of the changes in the interindustry pattern of trade restrictions which emerged from the kennedy round of tariff negotiations the principal conclusion of the analysis is that the pattern of protection which resulted from the kennedy round was shaped to minimize the domestic political disruption resulting from liberalization industries which faced significant import threats and whose characteristics enhanced their potential political influence were able to maintain tariff protection in the face of overall liberalization the potential impact of the agreed upon tariff reductions was partially undermined by the introduction of offsetting nontariff trade barriers ntbs in addition ntbs were introduced systematically in industries that were becom

total and per capita value of food loss in the united states there are few peer reviewed or major published studies that estimate the total amount of food loss in developed countries and even fewer attempt to estimate the monetary value we compiled estimates of the amount and value of food loss for more than 200 individual foods in the united states using the us department of agriculture s economic research service s loss adjusted food availability data and then aggregated these values to estimate the total value of food loss and the value by food group the results indicate that in 2008 the estimated total value of food loss at the retail and consumer levels in the united states as purchased at retail prices was 165 6 billion the top three food groups in terms of the value of food loss at these levels are meat poultry and fish 41 vegetables 17 and dairy products 14 looking more closely at the estimates for the consumer level this level of loss translates into almost 124 kg 273 lb of food lost from human consumption per capita in 2008 at an estimated retail price of 390 capita year food loss represents a significant share of household food expenditures our estimates suggest that the annual value of food loss is almost 10 of the average amount spent on food per consumer in 2008 and over 1 of the average disposable income this consumer level loss translates into over 3 kg 0 7 lb of food per capita per day valued at 1 07 day our estimates of the total value of food loss in the united states and loss estimates by food group are useful in that they can generate awareness of the issue among the food industry members governments and consumers potential large scale approaches and economic incentives to mitigate food loss in developed countries are also discussed

business cycles and the exchange rate system some international evidence this paper investigates the differences in time series behavior of key economic aggregates under alternative exchange rate systems we use a postwar sample of 49 countries to compare the behavior of output consumption trade flows government consumption spending and real exchange rates under alternative exchange rate systems pegged floating and cooperative systems such as the ems we then examine evidence from two particular episodes involving canada and ireland of changes in the exchange rate system aside from greater variability of real exchange rates under flexible than under pegged nominal exchange rate systems we find little evidence of systematic differences in the behavior of macroeconomic aggregates or international trade flows under alternative exchange rate systems these results are of interest because a large class of theoretical models implies that the nominal exchange rate system has important effects on a number of macroeconomic quantities

u s protection and intra industry trade the message to developing countries the purpose of this article is twofold first i provide recent evidence on the characteristics of u s intra industry trade with individual countries and regions which can be compared and contrasted with earlier work intra industry trade is defined as the cross hauling of similar goods between trading partners for example the united states exports automobiles to germany and imports automobiles from germany at the same time in the empirical work that follows i use a simple index that equals zero when there is no two way trade in a product and one when exports and imports of a product are equal 2 the present study provides an analysis of recent trade data 1984 and of u s intra industry trade at the four digit sic level that includes intraindustry trade between the united states and other industrialized countries canada japan the european community ec newly industrialized countries brazil mexico and developing regions caribbean basin south america second i examine the possibility that the trade liberalizing effects of intra industry trade are likely to extend to u s trade with developing countries this second issue is particularly important since recent work makes it clear that post kennedy round and post tokyo round protectionism among the industrial countries remains biased against manufactured exports from developing countries 3 the results are significant in three respects first there was consistent evidence that intra industry trade is dominated by cross flows of intermediate goods 4 more specifically intra industry trade occurs primarily in made to order intermediate goods furthermore intraindustry trade occurs predominantly in product lines in which efficient production is small scale production those findings hold not only for

inequality and the us import demand function in this paper we build a model of trade in vertically differentiated products and find that income inequality can affect the demand for imports even in the presence of homothetic preferences the empirical importance of changes in inequality on the demand for imports is then assessed by examining panel data for 36 developing and developed countries for the 1980 1997 period we find significant evidence supporting our prediction that inequality has a large influence on the demand for imports moreover we find that in line with the predictions of our theoretical model this influence is positive for high income countries countries that produce the high quality variety of the vertically differentiated product and negative for low income countries countries that produce the low quality variety of the vertically differentiated product

inequality nonhomothetic preferences and trade a gravity approach we construct the first direct classification of goods as luxuries or necessities that is compatible with international trade data we then use it to test an idea that has not been tested directly in the literature countries income distributions are important determinants of their import demand and in particular of the difference in their import demands of luxuries versus necessities we interpret this result with the aid of a model in which preferences are nonhomothetic thus relaxing a long held and standard but empirically dubious assumption in the theory of international trade our model is strongly borne out by the results imports of luxuries increase with the importing country s inequality and imports of necessities decrease with it our calculations imply that if income distribution in the united states became as equal as in canada the united states would import about 9 13 fewer luxury goods and 13 19 more necessities

an institutional approach to cross national distance cross national distance is a key concept in the field of management previous research has conceptualized and measured cross national differences mostly in terms of dyadic cultural distance and has used the euclidean approach to measuring it in contrast our goal is to disaggregate the construct of distance by proposing a set of multidimensional measures including economic financial political administrative cultural demographic knowledge and global connectedness as well as geographic distance we ground our analysis and choice of empirical dimensions on institutional theories of national business governance and innovation systems in order to overcome the methodological limitations of the euclidean approach we calculate dyadic distances using the mahalanobis method which is scale invariant and takes into consideration the variance covariance matrix we empirically analyze four different foreign expansion choices of us companies to illustrate the importance of disaggregating the distance construct and the usefulness of our distance calculations which we make freely available to managers and scholars

does the linder effect hold for differentiated agri food and beverage product trade using a generalized gravity equation this study tests for the linder effect in differentiated agri food product trade i e as the demand structures of two countries become more similar their trade intensity increases two proxies of demand structure the balassa index and the absolute value of the difference in per capita gross domestic products gdps of trading partners are used to capture the linder effect in addition two measures of bilateral trade the grubel and lloyd gl index and the value of bilateral trade are used as the dependent variable this study investigates the role of the linder effect in explaining the trade of 37 differentiated agri food and beverage products categorized into eight product groups cereals fresh fish frozen fish vegetables fresh fruit processed fruit tea and coffee and alcoholic beverages the data covers trade across 52 developed and developing countries from 1990 to 2000 the type of proxy used for the linder effect and the way in which bilateral trade

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

intra industry specialization in a multi country and multi industry framework the paper tests alternative hypotheses as to the factors determining the extent of intra industry trade defined as the share of this trade in total trade in a multi country and multi industry framework the empirical results show that the extent of intra industry trade in a particular industry between any two countries depends on the characteristics of the industry and the countries concerned the explanatory power of the regressions for the entire group of countries exporting manufactured goods as well as for trade among the developed countries is relatively high and practically all the hypotheses concerning the impact of industry trade are supported by the empirical results lower coefficients of determination have been obtained for trade between developed and developing countries and for trade among developing countries but the estimates generally support the hypotheses put forward in the paper in these cases also

intra tourism trade income distribution and tourism endowment an econometric investigation empirical investigation nowak et al 2012 points out that vertical intra industry trade viit in europe is the dominant type of intra industry trade iit in the tourism sector this article is the first in tourism literature to test separately the determinants of vertically and horizontally differentiated services using the most recent models in the theory of iit we examine bilateral trade among all trading partners of the sample of european countries covering the period from 2000 to 2008 we show that differences in gross domestic product per capita and the income distribution overlap as well as cultural proximity are the most significant driving forces behind viit for european countries geographic distance has a negative effect whereas specific tourism endowments and relative size of the economies are less conclusive these results confirm theory predictions and most of the empirical findings related to the pattern of viit for the manufacturing sector as expected we find that determinants

intra firm trade abstract the study analyses intra firm trade that is the estimated one third of world trade which is transacted between affiliated parties as firms realize the increasing potential for integrating their operations throughout the world they are contributing to significant shifts in the patterns of interntional trade and industrial development as emphasized here international trade is inextricably linked to the growing and substantial share of transactions between affiliated parties conveyed through multinational enterprises

trade costs 1870 2000 what has driven trade booms and trade busts in the past century and a half was it changes in global output or in the costs of international trade to address this question we derive a micro founded measure of aggregate bilateral trade costs based on a standard model of trade in differentiated goods these trade costs gauge the difference between observed bilateral trade and frictionless trade in terms of an implied markup on retail prices of foreign goods thus we are able to estimate the combined magnitude of tariffs transportation costs and all other macroeconomic frictions that impede interna tional trade but that are inherently difficult to observe we use this measure to examine the growth of global trade between 1870 and 1913 its retreat from 1921 to 1939 and its subsequent rise from 1950 to 2000 we find that trade cost declines explain roughly 55 percent of the pre world war i trade boom and 33 percent of the post world war ii trade boom while a precipi tous rise in trade costs explains the entire inter

bilateral trade and similarity of income distributions the role of second moments this letter uses an augmented gravity model to revisit the effect of similarity in income distributions on bilateral trade flows we document a robust new empirical regularity while differences in average incomes between two countries increase trade differences in income dispersion reduce it our result sheds new light on the linder hypothesis and stresses the importance of demand based theories of international trade

aggregate demand shifts income distribution and the linder hypothesis the intraindustry trade literature emphasizes nonhomothetic preferences and incomes as important determinants of aggregate demand and trade patterns the authors provide evidence for such preferences particularly that the structure of income driven demand shifts is related to indices of linder type product characteristics and that income distribution is a significant factor in determining aggregate expenditures these results imply that as general income levels rise the relative volume of trade in manufactured consumer goods should rise and the total volume of trade should rise independent of changes in the intercountry difference between income levels copyright 1996 by mit press

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

the determinants of intra european trade in manufactured goods abstract the determinants of intra european trade in manufactured goods are examined using three models the first model tests whether inter industry specialization between pairs of countries can be explained in terms of inter industry differences in factor intensities and inter country differences in factor endowments the second model tests the effects of country and industry characteristics in the extent of intra industry specialization the third model combines the first two to analyse the determinants of bilateral gross trade in individual industries the empirical results support the specific hypotheses put forward to specify the models

coping with terms of trade shocks pegs versus floats the choice of the exchange rate regime has always been an area of great controversy and debate the discussion has once again taken center stage in the developing world the sequence of currency crises in the 1990 s the success of cultency board arrangements the dollarization plan of ecuador and the apparent swing toward flexible regimes of many emerging economies has revived interest in this debate milton friedman 1953 argued that one of the most important advantages of flexible regimes over fixed regimes is that they can smooth adjustment to real shocks even in the presence of nominal rigidities ever since this has been one of the least disputed benefits attributed to fully flexible exchange rate regimes subsequent to friedman many theories of the international transmission of real shocks have confirmed the original intuition that the shortrun responses to terms of trade shocks should be different across exchange rate regimes here i look at a post bretton woods sample of 74 developing countries to test whether flexible regimes can buffer terms of trade shocks better than fixed regimes

intra industry trade in agrofood sectors the case of the eec meat market examination of intra industry trade iit and of its determinants has so far been confined to industrial commodity markets taking the case of red meat the possibility of trade overlap in a typical agroffod commodity is observed further based on previous theoretical analyses and empirical indications it tests formally a general and a restricted set of country and industry or demand and supply hypotheses which being particular to the eec meat market may account for cross country variations in iit in 1988 results suggest that taste overlap as approached by countries cultural and economic convergence as well as the imperfectly competitive structure of the market as supported by product differentiation significantly explain iit despite some methodological shortcomings there seems to be ample scope for the application of similar models in other agrofood sectors in what remains a relatively under researched area
