devaluation and the j curve some evidence from ldcs within the international trade literature it is not uncommon to find arguments about whether devaluation will improve the trade balance it is argued that the flows of goods respond only with time lags to changes in the exchange rate the j curve terrn is used to describe the movement over time of the trade balance it may deteriorate at first and improvement may come later this paper presents a method by which one could detect the existence of the j curve the method is applied to four developing countries the empirical evidence supports the pattern of movemnent described by the j curve a major policy option for a country facing a persistent balance of payments deficit is said to be devaluation of its currency within the international trade literature it is not uncommon to find arguments about whether devaluation will improve the trade balance or the balance of payments for example proponents of the elasticities approach describe the necessary and sufficient conditions for an improvement in the trade balance in terms of elasticities of demand and supply referred to as the marshall lerner condition while there is abundant empirical evidence to suggest that these conditions are indeed met at least for industrial countries there have been circumstances under which 2 devaluation has not been successful for example one might wonder why the u s trade balance deteriorated so much in 1972 despite the devaluation of the dollar in 1971 this unfavorable effect of devaluation on the trade balance is termed the j curve phenomenon received for publication august 23 1984 revision accepted for publication november 26 1984 the university of wisconsin milwaukee i would like to thank two anonymous referees for their valuable comments on the initial draft of this paper 1 proponents of the absorption approach e g alexander 1952 describe how devaluation may change the terms of trade increase production and switch expenditures from foreign to domestic goods thus improving the trade balance international monetarists argue that devaluation reduces the real value of cash balances and or changes the relative price of traded and nontraded goods thus improving both the trade balance and the balance of payments 2 for an cstimate of the elasticities see houthakker and magee 1969 and warner and kreinin 1983 the former study provides the elasticities estimates under fixed exchange rates and the latter under floating rates this content downloaded from 157 55 39 17 on wed 31 aug 2016 04 39 37 utc all use subject to http about jstor org terms

exchange rate policies and endogenous time preference a dynamic analysis of a small open economy abstract the effects of exchange rate policies are examined for a small open economy with endogenous rate of time preference using optimizing framework and introducing money into the utility function it is shown that a depreciation of the domestic currency generates a surplus in the current account it also leads to an increase in consumption and a decrease in the holdings of real balances in the long run

the j curve in the emerging economies of eastern europe devaluation or depreciation of a currency worsens the trade balance before improving it resulting in a j curve pattern a new definition of the hypothesis implies a short run deterioration combined with the long run improvement by using monthly data over the january 1990 june 2005 period from 11 east european emerging economies most of which are the new european union eu members or the eu candidate countries this article uses the bounds testing approach to cointegration and error correction modelling and finds empirical support for the j curve hypothesis in three countries of bulgaria croatia and russia the results have important implications for policymakers involved in economics in terms of using exchange rate policy as a policy device to achieve real convergence toward eu standards

supply side and demand side cost sharing in deregulated social health insurance which is more effective abstract microeconomic theory predicts that if patients are fully insured and providers are paid fee for service utilization of medical services exceeds the efficient level moral hazard effect in switzerland both demand side and supply side cost sharing have been introduced to mitigate this problem analyzing a panel dataset of about 160 000 adults we find both types of cost sharing to be effective in curtailing the use of medical services however when moral hazard mitigation is traded off against risk selection the minimum deductible supply side cost sharing option ranks first followed by the medium deductible demand side alternative making the supply side option somewhat more effective

income redistribution in a common labor market when households are mobile among jurisdictions income redistribution by individual jurisdictions creates fiscal externalities a model of interjurisdictional migration is used to study the nature of this redistributive externality analysis of optimal redistribution and optimal corrective subsidies from higher level governments shows that benefit levels for the recipients of income transfers and tax rates on mobile taxpayers should be equalized across jurisdictions a system of jurisdictions with a common labor market can achieve welfare improvements through coordination of domestic redistributive policy or through the intervention of a higher level government copyright 1991 by american economic association

effects of exchange rate risk on exports crosscountry analysis abstract in this paper we investigate the effects of exchange rate uncertainty on the aggregate exports of 19 developed and 67 developing countries using cross sectional data exchange rate uncertainty is found to be detrimental to the exports of both developing and developed countries developed countries exports however are found to be less sensitive to exchange risk than that of developing countries furthermore within the developing countries those who fixed their exchange rates to one major currency were found to be subject to less risk than the other developing countries

decentralisation of active labour market policy the case of swedish local employment service committees decentralisation of decision making in active labour market policy makes it possible to use local information to the fullest but may also impinge on the fulfilment of national objectives as suggested by principal agent theory the purpose of this study is to examine the effects of a swedish pilot programme in 1996 which strengthened the role of the local authorities in labour market policy in parts of the country survey evidence suggests a non negligible divergence between the objectives of the municipality representatives and the central government s goals regarding programme effects our econometric findings do not indicate any increase in geographical lock in of the unemployed but decentralisation seems to spur local initiatives in the form of labour market programmes organised by the municipalities in addition targeting on outsiders is to some extent more common in municipal projects than in others

tariffs real exchange rates and the trade balance in a two country world abstract an intertemporal model of a two country world in which optimizing agents consume three goods importables exportables and nontradables is developed to investigate a tariffs effects on real interest rates real exchange rates and the trade balance real interest rates and real exchange rates are shown to move asymmetrically across countries in response to a temporary tariff we also show that in contrast to the findings of two tradable good models a temporary tariff may actually worsen the trade balance of both deficit and surplus countries even when there are no cross country differences in tastes

deviations from purchasing power parity and capital flows abstract this article examines the implications of deviations from purchasing power parity ppp for an investor s portfolio decision and the consequent capital flows in a two country intertemporal model with complete financial markets in the presence of deviations form ppp investors from different nations hold disparate portfolios and the equilibrium that results is not a pooling one we solve eplicitly for asset demands and derive the relationship between the direction of capital flows and deviations from ppp in contrast to the small country assumption in the existing literature the world interest rate in this model is determined endogenously

determinants of international trade flows this paper models and estimates import demand and demand for export functions for 19 industrial countries although primary emphasis is placed on the period of generalized floating exchange rates 1972 through 1980 estimates are also provided for the fixed exchange rate years 1957 1970 thus making possible a comparison between the two eras aside from the conventional income and price variables the paper assesses the effect of variations in the exchange rate and in the expected exchange rate on real trade flows additionally it estimates an unrestricted lag structure of the effect of price and exchange rate variations on imports

inflationary finance in an open economy abstract models of inflationary finance that consider trade and capital flows generally conclude that openness curtails the ability of governments to impose the inflation tax due to currency substitution this paper models two channels that allow central banks to increase inflation tax revenue by opening the economy first central banks can open the capital account subject to a reserve requirement on capital inflows revenue maximization produces a smaller reserve requirement on foreign capital inflows that on domestic deposits second central banks can impose prior import deposits to broaden the monetary base in order to use the inflation tax on imports as an alternative to tariff revenue

an asymmetric analysis of the j curve effect in the commodity trade between china and the us this paper follows a non linear ardl error correction approach to examine the presence of the j curve in the commodity level trade between the united states and china the analysis disaggregates the us china trade flows by commodities and separately examines the trade balance responses of 97 commodities to the changes in the real yuan us exchange rates the analysis at the commodity level alleviates potential aggregation bias that is present in earlier studies offering little evidence for long run asymmetric effects of exchange rate on the china us trade balance we find strong support for short run asymmetric effects in the case of two third of the commodities whereas significant long run asymmetric effects are present in the case of one third of the commodities including those commodities which command large shares in the china us trade

bilateral j curve between india and her trading partners india a land of over one billion people and one of the newly emerging industrial powers in the world is going through a slow but steady metamorphism for centuries india has played a major role in the international trade it was not uncommon to see her ships carrying silk and spices across the arabian seas and bringing back machine made textile invasions of india first by mughals and latter by the british through the east india company were all trade oriented india s presence in the world trade is relatively small at this time but is gaining momentum after independence in 1947 india for a brief period experimented with socialism the five year plans were mainly focused towards building infrastructure and development of small scale agriculture based industries the industrial development even though extremely important for growth played a secondary role the foreign investment was encouraged but only in the selected sectors of the economy however threat of nationalization a large bureaucracy corruption lack of understanding of the indian business practices and the requirement that a major share holder must be an indian national discouraged foreign capital investment in india during 1991 1992 india adopted a policy of trade liberalization to attract foreign capital and to encourage non resident indians to invest in their home country government of india established a separate unit within the home ministry whose main function was to expedite processing of applications india also relaxed the requirement that a major partner be an indian national india provided export subsidies to the exporters in terms of cash as well as foreign exchange so that they could import machines and raw materials exports responded to the trade liberalization and increased from 44 041 crores of rupees in 1991 1992 to 141 603 crores in 1998 1999 where one crore is equivalent to ten million in us dollar terms at a current exchange rate of 42 48 rupees per dollar this translates to an increase from 10 37 billion to 33 34 billion over eight years india also anticipates that through a major increase in the information technology mainly software industry her exports will increase to 90 billion by 2005 the trade liberalization has been accompanied by changes in the monetary policies the inflation rate has been reduced from about 12 to 9 per year the interest rates have declined from 14 to 10 and the exchange rate has been allowed to respond to market forces as a result from 1991 1992 to 1998 1999 the rupee has declined from 19 62 rupees per dollar to 42 48 rupees per dollar by december 2000 rupee had further devalued to 46 25 per dollar with a hope that it will further boost india s exports and improve her trade balance however the impact of currency depreciation on the trade balance is not instantaneous indeed there is ample evidence in the literature that after currency depreciation the trade balance worsens in the short run before improving in the long run since this pattern of movement of the trade balance over time resembles the letter j magee 1973 labelled it the j curve phenomenon magee argued that after devaluation contracts that are in transit at old exchange rates dominate the short run response of the trade balance over time new contracts at new prices begin to exert their favourable impact at this stage elasticities may increase leading to an eventual improvement in the trade balance of course the delayed response could also be due to lags in the process of increasing the production of exportables junz and rhomberg 1973 have identified five lags namely recognition lags decision lags delivery lags replacement lags and production lags only after the realization of these lags the trade balance could improve early studies that tried to investigate the impact of currency depreciation on the trade balance relied upon estimating the marshall lerner condition the condition

capital mobility and the current account abstract this paper analyzes the effect of unanticipated changes in the terms of trade on consumption expenditures and the current account in a small open economy simple formulas are obtained for the covariances of changes in consumption expenditures the current account and the expected current account with changes in the terms of trade it is shown that if investment is uncorrelated with the terms of trade a necessary condition for unanticipated changes in the terms of trade to be correlated with changes in consumption expenditures and the expected current account is that the real expected return on foreign bonds differs from the real expected return on domestic bonds

import content of exports and j curve effect this article investigates how the response to devaluation of trade balance is affected compared to j curve hypothesis by the presence of imported inputs in the production of exports using first the almon lag technique and then the cointegration and the generalized impulse response function analysis the j curve effect is examined in two sectors of turkish economy manufacturing and mining which use imported inputs at different rates based on the data covering the period from the first quarter of 1986 to the third quarter of 1998 our results indicate that in neither sector j curve exists and that the violation of the j curve effect is more severe in the sector with higher import content

devaluation and the trade balance in india stationarity and cointegration a study of devaluation and the trade balance in india corrects the data for nonstationarity previous empirical tests have used non stationary data the trade balance in india is not cointegrated with a number of variables including the exchange rate absorption elasticity and monetary models are compared and the monetary model performs better there has been no j curve in india and devaluations have had no significant long run effect on the trade balance

macroeconomic effects of active labour market programmes in a union wage setting model the recent western european policy debate on unemployment has emphasized the benefits of active labor market programs the authors analyze the effects on wage pressure and equilibrium employment in a union wage setting framework programs are wage reducing to the extent that they help maintain effective labor force participation but they may also weaken insider incentives for wage restraint as the disutility of layoffs becomes smaller targeting the long term unemployed is crucial for the success of active labor market policy since the welfare effects on the laid off then are more heavily discounted and employment opportunities are redistributed from insiders to outsiders copyright 1995 by royal economic society

brazil us commodity trade and the j curve currency devaluation or depreciation is said to temporarily worsen a country s trade balance and improve it later an effect that is called the j curve previous research that tested the j curve for brazil used the country s aggregate trade flows with the rest of the world and did not find support for the phenomenon in this article we consider the trade flows between brazil and a major trading partner the united states disaggregating their trade flows by commodity we then test the empirical validity of the j curve for each of the 92 industries that trade between the two countries we find support for the phenomenon in 31 industries therefore disaggregation by industry seems to yield some support for the phenomenon

the exchange rate and the balance of trade the turkish experience in this article we examine the responsiveness of turkey s trade balance to devaluation accompanied by trade liberalisation our results show that the trade balance was responsive to changes in the exchange rate that were brought about by the economic reforms introduced in the 1980s suggesting that exchange rate policy was able to create and maintain a satisfactory balance of trade position in the 1980s and early 1990s

critical debt and debt dynamics we study the debt dynamics and sustainable debt for an open economy which borrows from abroad in order to nance consumption to service the debt the country may exploit a renewable resource we show that there is for every resource stock r a critical level bh r of debt above which debt tends to in nity but below which it may be steered to zero we demonstrate how to compute bh r using an ode of steepest descent if the economy maximizes a discounted integral of utility depending on consumption and the resource stock the critical debt bh r may be reached in nite time in such a situation slight perturbations of the optimal consumption lead to insolvency the maximum principle ceases to be valid in this case 2000 elsevier science b v all rights reserved jel classixcation c61 f32 f34 o16

determinants of international trade flows the case of developing countries abstract the question of magnitude and the time path of the trade flows to changes in the exchange rates and to changes in the price level is of emitent practical importance to assess the above proposition a distributed lag structure is imposed on the relative prices and on the effective exchange rate as the determinants of trade flows then import and export demand functions are estimated for a sample of developing countries using the almon procedure the empirical findings appeared to sustain orcutt s early conjecture that trade flows adjust differently to different price stimuli more precisely it was found that imports and exports reactions were quicker and the total response time was shorter when an exchange rate rather than relative prices caused a change in international prices

anticipated versus unanticipated terms of trade shocks and the j curve phenomenon abstract using a dynamic stochastic general equilibrium dsge model we examine the impact of anticipated and unanticipated terms of trade tot shocks on aggregate output inflation and the trade balance tb this allows us to offer an alternative explanation of the j curve phenomenon we find that an unanticipated tot shock increases real output as well as inflation but the j curve phenomenon may not exist under a certain condition however under the same condition an anticipated tot shock leads to the j curve effect we find that our main result concerning the j curve phenomenon continues to hold even if the assumption of rational expectations about the tot is relaxed further analysis reveals that the presence of a cost channel of monetary policy increases the intensity of the j curve effect assuming plausible parameter values while using a more general model calibration results support our theoretical predictions

effects of exchange rate variations on bilateral trade with a vehicle currency evidence from china and singapore abstract using a testable gravity type bilateral trade model derived from an underlying demand and supply model this paper explores the effects of exchange rate variations on bilateral trade in an exchange rate regime with a vehicle currency the introduction of the vehicle currency allows us to figure out whether variations in the trade volume due to the fluctuation of the bilateral exchange rate are primarily due to changes in demand or in supply or both more specifically in this theoretical framework the appreciation of one country s currency against the vehicle currency is expected to promote its imports but the effect of revaluation of the country s currency against the vehicle currency on its exports is ambiguous moreover high volatility of the exchange rate of one country s currency against the vehicle currency is also expected to depress its import volume from the empirical point of view the decomposition of the bilateral exchange rate of two currencies into the bilateral rates of these two currencies against the vehicle currency provides a new alternative to avoid the econometric problem of potential reverse causality in assessing the effects through compiling a novel monthly bilateral trade dataset between china and singapore over 21 years or 252 months we empirically test the predictions of our model which get robust support from the results

the terms of trade and the current account the harberger laursen metzler effect the paper examines the effect of terms of trade changes on a small country s spending and current account assuming optimizing behavior in an intertemporal framework with perfect international capital mobility a temporary future terms of trade deterioration implies a deterioration improvement of the trade balance whereas a permanent terms of trade deterioration has an ambiguous effect depending on the rate of time preference nominal and real variables are considered via exact price indexes two periods and an infinite horizon are examined

the j curve a literature review due to lag structure currency devaluation is said to worsen the trade balance first and improve it later resulting in a pattern that resemble the letter j hence the j curve phenomenon since its introduction by magee in 1973 brooking papers on economic activity 1 pp 303 25 a large number of studies have attempted to test the phenomenon using different techniques and different model specifications the results are at best ambiguous and deserve to be collected together for the future generation of researchers and graduate students this paper fills such a vacuum in the literature by reviewing the j curve related empirical papers

transitory and permanent disturbances and the current account an empirical analysis in the intertemporal framework the intertemporal models of current account determination demonstrate that in the analysis of the current account balance of a country it is important to distinguish between transitory and permanent disturbances in income and relative prices this paper attempts to decompose the observed data on income and real exchange rate into transitory and permanent components and then uses the decomposed series to test the empirical validity of the predictions of the intertemporal models evidence from the united states and japan provide very limited support for the intertemporal models in terms of the effects of transitory and permanent changes in income on current account balance for both us and japan the study finds that permanent changes in real exchange rate have significant effects on the current account balance statistical tests find no evidence of hysteresis in the trading relations of the two countries

do devaluations improve the trade balance the evidence revisited do devaluations improve the trade balance the evidence revisited this paper reexamines the effectiveness of devaluation in trade balance adjustment the question is addressed in a framework which improves the previous empirical literature in several respects the evidence indicates that devaluations have been a successful tool in inducing trade balance adjustment in particular nominal devaluations are found to result in significant real devaluations that last for at least three years and the real devaluation induces significant trade flows that are distributed over a two to three year period the evidence comes from two different samples 1953 73 and 1975 84 involving twenty seven countries and sixty devaluation episodes 1 introduction do devaluations affect real magnitudes in particular the trade balance a devaluation may effect the trade balance through two channels devaluation of the real exchange rate and a direct effect on domestic absorption the traditional approach stresses the first channel a nominal devaluation is assumed to change the real exchange rate a relative price and thus improve competitiveness in turn if relative prices the terms of trade in a two country two good model affect the trade balance devaluation will be successful in the sense of improving the trade balance ceteris paribus the absorption effect becomes the sole or most important channel in the monetary approach in a world in which all goods and assets are perfect substitutes prices are exogenously given for the small country and wages and prices are flexible in both nominal and real terms a devaluation increases the price level by the same percentage the increase in the price level reduces real balances and thus domestic absorption dornbusch 1973 883 has argued that if such a real balance effect is not present then it might stand to reason that the effects of devaluation are negligible not that there must be other powerful avenues through which it exerts its effects emphasis added the controversy over the effects of devaluation on the trade balance arises because according to frenkel and johnson 1976 42 the monetary approach rejects the emphasis given to the role of relative prices in the analysis of devaluation global monetarists argue that neither of the links in the chain postulated by the traditional approach is likely to hold in practice see laffer 1977 the major disagreement centers on the question of the effectiveness of nominal devaluation to affect the real exchange rate and the importance of the latter in influencing trade flows theoretical arguments have not settled the issue the question is as strongly debated today as it was forty years ago see for example branson 1983 katseli 1983 kaldor 1983 nashashibi 1983 and mckinnon 1981 nor does it seem that the available empirical evidence leads to a consistent answer the best known studies cooper 1971 laffer 1977 salant 1977 miles 1979 gylfason and risager 1984 reach contradictory conclusions 1 cooper and gylfason and risager find that devaluations improve the trade balance or current account while laffer and miles conclude exactly the opposite salant finds that devaluations improve the trade balance but not as often as the overall balance of payments in the face of such diverse findings frenkel 1984 suggests that a reexamination of the issue would be useful indeed himarios 1985 shows that a close examination of miles s widely quoted study reveals serious deficiencies that once addressed lead to opposite results this paper provides new evidence concerning the effectiveness of devaluation in trade balance adjustment the approach differs from past studies in several respects it differs from cooper s laffer s and salant s studies in that it accounts for the effects of other variables that affect the trade balance

deterioration of the terms of trade and capital accumulation a reexamination of the laursen metzler effect abstract this paper analyzes the effect of both a permanent and a temporary deterioration in the terms of trade on a small open economy the model based on intertemporal optimization emphasizes the labor leisure choice and the role of capital accumulation the transitional dynamics is shown to depend upon the long run response of the capital stock to the terms of trade shock this consists of a negative substitution effect together with a positive income effect whether or not the laursen metzler effect holds depends upon whether the income effect dominates the substitution effect

trade in nominal assets and net international capital flows abstract nominal assets play a major role in international financial markets while trade in indexed bonds is limited as a result agents are exposed to both price and exchange rate uncertainty nonetheless previous research on net capital flows has assumed the presence of a risk free vehicle to intertemporal asset trade in this paper we develop a general equilibrium intertemporal model with trade limited to nominal bonds and equity we find that exposure to nominal risk dampens net capital flows thus making economies effectively more closed

the j curve effect and us agricultural and industrial trade this paper examines the j curve hypothesis for us agricultural and manufactured goods using the shiller lag model the results support the j curve effect for agricultural goods but not for manufactured goods these findings explain why many studies in the literature fail to support the j curve phenomenon there are two explanations for these findings 1 the aggregation bias of data that combine both agricultural and manufactured goods and 2 the country under study is often an industrial nation like the us or japan with a high proportion of manufactured goods in both exports and imports

health insurance and the demand for medical care evidence from a randomized experiment we estimate how cost sharing the portion of the bill the patient pays affects the demand for medical services the data come from a randomized experiment a catastrophic insurance plan reduces expenditures 31 percent relative to zero out of pocket price the price elasticity is approximately 0 2 we reject the hypothesis that less favorable coverage of outpatient services increases total expenditure for example by deterring preventive care or inducing hospitalization

intertemporal optimizing models of trade and current account balance a survey abstract this study surveys the intertemporal optimizing models of trade and current account balance that were developed calibrated and empirically tested since they came into vogue in the 1980s the implications of these models often differ from those of static and dynamic conventional non optimizing models the literature on optimizing models has not only grown reasonably fast but has also witnessed significant advances in methodology and these models have culminated into a distinct strand of new open economy macroeconomics the studies conducted until the late 1980s have used deterministic perfect foresight models while several studies conducted since the 1990s relax the perfect foresight and certainty equivalence assumptions and develop stochastic dynamic general equilibrium models to account for uncertainty confronting the optimizing agents the future research needs to explore the possibility of tracing any preferred specification of household preferences model the effect of time varying discount factor on household utility function and intertemporal budget constraint examine the role of costs in international trade place a parallel emphasis on the empirical verifications of theoretical propositions examine the relative performance of optimizing vis a vis non optimizing models and rationalize the extreme propositions of perfect and imperfect capital mobility in the wake of moderately open capital accounts

the capital inflows problem revisited a stylized model of southern cone disinflation in the late 1970s countries in latin america s southern cone initiated attempts to lower domestic inflation rates through the progressive reduction of a preannounced rate of exchange rate devaluation the stabilization programs gave rise to massive capital inflows real exchange rate appreciation and current account deficits this paper develops a stylized intertemporal framework in which the effects of a credible preannounced disinflation scheme can be studied it is shown that even when agents have perfect foresight and markets clear continuously the capital inflows phenomenon and the associated real appreciation may result while unanticipated permanent inflation changes are neutral in the paper anticipated inflation is neutral only in exceptional circumstances a preannounced disinflation operates by altering the path of an expenditure based real domestic interest rate that depends on expected changes in the prices of liquidity services and nontradable consumption goods

bilateral j curve between the uk vis a vis her major trading partners currency depreciation is said to worsen the trade balance first before resulting in an improvement yielding a short run pattern labelled the j curve phenomenon while early studies tested the j curve by using aggregate trade data a few recent studies have employed bilateral data mostly between the us and her major trading partners in this paper we extend the literature by considering the experience of the uk we test the phenomenon between the uk and her twenty major trading partners by employing data over 1973q1 2001q3 period in most instances we find no support for the j curve in the short run in the long run only in five cases has the exchange rate had significant impact on the bilateral trade balance

an evaluation of the swedish system of active labour market programmes in the 1990s we investigate the presence of short and long term effects from joining a swedish labor market program vis a vis more intense job search in open unemployment overall the impact of the program system is found to have been mixed joining a program has increased employment rates among participants a result robust to a misclassification problem in the data on the other hand it has also allowed participants to remain significantly longer on unemployment benefits and more generally in the unemployment system this being particularly the case for those entitled individuals entering a program around the time of their unemployment benefits exhaustion

the j curve and nafta evidence from commodity trade between the us and mexico the north american free trade agreement nafta was predicted to have a substantial impact on the us mexico trade especially on specific importing and exporting industries in this article we use annual industry level export and import data from 1962 to 2004 to discern both the short and long run effects of real exchange rate depreciation on the mexico us trade balance as well as the effects of nafta on this trade we find that peso depreciation has a positive long run effect on 24 of 102 mexican industries and a negative short run effect on 19 of 102 industries only a small fraction 7 of 102 industries show any support for the j curve hypothesis nafta has had a significant effect on a significant number of the industries however

stock prices and the effective exchange rate of the dollar the literature on the relation between stock prices and exchange rates is very poor and includes few studies that have argued that exchange rate changes do effect stock prices by relying on the portfolio approach to exchange rate determination it is argued that a change in stock prices could also have an impact on exchange rates i e there could be a two way relationship between exchange rates and stock prices granger concept of causality as well as cointegration technique are employed to support this conjecture the empirical results show that there is bidirectional causality between stock prices measured by s p 500 index and the effective exchange rate of the dollar at least in the short run the cointegration analysis reveals that there is no long run relationship between two variables

do exchange rate changes have symmetric or asymmetric effects on the trade balances of asian countries abstractrecently the linear ardl approach was modified and a non linear version of the same approach that is used mostly to assess asymmetric effects of some exogenous variables on the dependent variable was introduced the non linear model was recently used by one study to show that indeed exchange rate changes have asymmetric effects on the trade balance of a few advanced countries the same was demonstrated for transition economies by another study in this article we provide additional asymmetric effects from seven asian economies by showing that in most cases we find evidence of short run and long run asymmetric effects of exchange rate changes on the trade balance like other studies our findings are country specific

trade policy adjustment in ldcs a short run view the article deals with the role of tariff protection and exchange rate policies in ldcs after a terms of trade shock has occurred and a new equilibrium is to be attained constraints concerning the domestic foreign and public sectors are specified it is shown that the optimal response to the shock depends on the domestic features of the economy as well as on its trade openness in particular protectionist attitudes may well be justified and anti trade policies may be helpful to ease adjustment

the j curve revisited an empirical examination for the united states abstract this paper examines empirical evidence for trade prices and quantities for the united states to determine whether j curve effects have occurred in recent history empirical estimates of exchnage rate pass through and trade volume responses to exchange rate changes for the 1967 to 1987 period indicate that the often told tale of trade balance deterioration and then improvement the j shaped adjustment path has not typically been experienced by the united states expenditures on imports have typically increased following dollar depreciations primarily as a result of relatively inelastic import volume responses export earnings have been seen to rise only marginally during these same dollar depreciations due to increases in export prices and the subsequent reductions induced in export volume the long run merchandise trade balance adjustment path is seen to resemble a sine wave rather the a j

exchange rate of the us dollar and the j curve the case of oil exporting countries abstract this study examines the effects of changes in the exchange rate of the us dollar on the trade balances of three oil exporting countries namely iran venezuela and saudi arabia an exchange rate pass through model is applied to allow changes in the exchange rate of the dollar to affect prices of traded goods then the impact of changes in prices on the quantities of imports and exports of these economies is estimated the results suggest a partial exchange rate pass through to these countries import and export prices in terms of the us dollar while the three countries raise the price of their primary export namely crude oil in response to a depreciation of the dollar saudi arabia s long run pricing strategy in securing a larger market share stands in contrast to that of the two other opec members the sum of the estimated long run price elasticities of demand for imports and exports is found to exceed unity for iran and venezuela but less than unity for saudi arabia

bargaining and wage resistance in an open macroeconomic model this paper develops a model of an open economy in which wages and employment are determined by bargaining between firms and unions it can be regarded as an extension of an earlier paper ellis and fender 1985 to an open economy this allows us to investigate a number of contemporary issues in particular we shall explore some aspects of wage resistance the tendency for nominal wages to rise so as to offset either partially or totally any rise in the aggregate price level empirical evidence on wage resistance has been produced by sachs i980 who also shows that the assumption of real as opposed to nominal wage rigidity reverses the conclusions about the relative efficacy of monetary and fiscal policy in the fleming mundell model a number of other papers have incorporated wage resistance sometimes due to wage indexation see for example gray 1976 for analysis in a closed economy context and marston i982 modigliani and padoa schioppa 1978 and eichengreen i983 for open economy models in all these papers however wage resistance is assumed rather than derived from more basic assumptions about agents behaviour however some work has appeared recently which attempts to endogenise wage resistance in a closed economy by modelling union employer bargaining see for example mcdonald and solow i98i and ellis and fender i985

exchange rate based disinflation wage rigidity and capital inflows real exchange rate appreciation usually accompanies stabilization programs based on the exchange rate one thing that causes the real exchange rate to appreciate is the capital inflows that follow liberalization of the capital account and the financial market capital inflows cause the exchange rate to appreciate in part because of the resulting increase in expenditures this appreciation is exacerbated if there is some price rigidity and if control of the money supply is only partial all these conditions existed during chile s experiment with exchange rate based disinflation between 1978 and 1981 simulating what might have been the authors study how exchange rate based disinflation affects expenditures switching and reduction when wages are partially indexed in some segments of the labor market the paper also shows the extent to which a more flexible rule on wage indexing would have offset the adverse impact of lower capital flows on protected sector employment

the demand for episodes of treatment in the health insurance experiment abstract this paper analyzes claims data from the rand health insurance experiment which were grouped into episodes of treatment the insurance plans in the experiment have coinsurance and a cap on out of pocket spending using new statistical techniques to adjust for the increased sickliness of those who exceed the cap the effects of coinsurance on cost per episode and number of episodes are estimated cost sharing reduced the number of episodes but had little effect on cost per episode people in the experiment responded myopically as their current insurance status changed through the year the price elasticity of spending was about 0 2 throughout the range of coinsurance studied when data permit it the study of episodes complements analyses of annual medical spending by revealing more about how decisions to spend are made within the year

impacts of the us dollar usd exchange rate on economic growth and the environment in the united states abstract this paper investigates the impact of the usd exchange rate on economic growth and the environment in the united states by using a structural vector autoregression svar model the analysis is based on quarterly country level data on the real trade weighted us dollar index petroleum consumption renewable energy consumption net imports of pollution intensive products real gdp and co2 emissions during the 1989 2015 the result shows that the usd exchange rate is positively related to petroleum consumption net imports of the united states in pollution intensive industries with major u s trading partners real gdp and co2 emissions moreover petroleum consumption increases real gdp and domestic co2 emission levels while net imports of pollution intensive products decrease real gdp and does not significantly affect co2 emissions

the j curve dynamics of turkey an application of ardl model this article seeks an empirical evidence for the existence of the j curve phenomenon both in the short run and long run for turkey over the period 1980 2005 the bounds testing cointegration approach is employed to estimate the trade balance model an augmented form of granger causality analysis is implemented between trade balance real effective exchange rates foreign income and domestic income the stability of the short run as well as long run coefficients in the trade balance model is tested too the empirical results suggest that the j curve phenomenon is supported only in the short run whilst causality tests reveal mix results the parameter stability tests seem to be inconclusive

how sensitive is commodity trade flows between us and india to currency depreciation previous studies that investigated the impact of real depreciation of the rupee on indian trade balance used aggregate trade data and provided no support for real depreciation to be effective in improving india s trade balance in this article we disaggregate the indian trade data by commodity and consider the sensitivity of each industry s inpayments export value and outpayments import value to real rupee dollar exchange rate annual data over the period of 1962 to 2004 from 40 industries that trade between the two countries as well as bounds testing approach are used to show that while in half of the industries real depreciation of rupee has short run effects on inpayments and outpayments the short run effects do not last into the long run in majority of the cases

is there a long run relation between the trade balance and the real effective exchange rate of ldcs abstract using quarterly data over 1973 1988 period the cointegration analysis is used and it is shown that the trade balance and the real effective exchange rate of some ldcs are cointegrated in the long run this approach is argued to be a close substitute for testing the marshall lerner condition

decentralization decisions in bureaucracies as a principal agent problem abstract in this paper a positive theory of internal bureaucratic decision making is presented a model is formulated to explain why some decisions within a public bureaucracy are decentralized while others are not the explanation using the notions of principal agent theory involves such factors as different access to information and different objectives of central and decentral actors an empirical test of the model is carried out using data on decisions of local government in the netherlands on capacity reductions in hospitals

terms of trade and current account dynamics a methodological critique this paper suggests that the recent intertemporal studies concerning the implications of terms of trade deterioration on the current account of a small open economy may suffer from significant methodological deficiencies the study demonstrates that while the assumption of a small open economy represents a legitimate modeling simplification the analysis of the impact of perturbation of the terms of trade on the current account of this small open economy is methodologically erroneous in particular the paper demonstrates that a given pattern of terms of trade deterioration may be associated with opposing evolutionary patterns of the current account of this small economy this paper argues that the methodology employed by several influential intertemporal studies concerning the relationship between the terms of trade and the current account of a small economy suffers from critical deficiencies it demonstrates that while the assumption of a small open economy confronting exogenously determined terms of trade represents a legitimate modeling simplification the analysis of the impact of perturbations of this terms of trade on the small open economy and on its current account is methodologically erroneous in particular the paper demonstrates that a small economy may experience diametrically opposing evolutionary patterns of the current account in association with a given pattern of terms of trade deterioration the paper suggests therefore that predictions based on this literature are in need of reassessment these intertemporal studies of the relationship between the terms of trade and the current account of a small economy have been conducted under the simplifying assumption that perturbations in the terms of trade are exogenous and do not affect the world interest rate 2 this approach may reflect a valid simplification as long as the study is concerned with exportable goods whose prices are insignificant in the determination of the general price level in the world economy however if the focus of the analysis is a small country that exports a group of commodities such as agricultural goods or industrial goods a change in the terms of trade for the small economy may reflect fundamental changes in the world relative prices that are

vertical product differentiation and the import demand function theory and evidence in this paper we use a model of vertical product differentiation to cast doubt on the general validity of the import demand function as specified in macroeconomic models the empirical importance of our theoretical concerns is then established according to our first hypothesis the share of a good s imports in total imports is non increasing in domestic wages if the country has comparative advantage in high quality varieties of this good the second hypothesis states that the share of a good s imports is increasing in non wage domes tic income if the country has comparative advantage in high quality varieties of this good

the balance of trade and exchange rates theory and contemporary evidence from tourism abstract the purpose of this study is to investigate the effects of exchange rate depreciations and appreciations on the tourism trade balance specifically we employed linear and nonlinear autoregressive distributed lag ardl cointegration techniques to analyze the extent to which currency depreciations and appreciations affect the united states u s bilateral tourism trade with canada mexico and the united kingdom u k the results showed that the depreciation of the u s dollar subsequently improves the u s trade balance with all three trading partners however while the appreciation of the u s dollar deteriorates the u s bilateral tourism trade balance with canada and the u k it does not ultimately affect the u s bilateral tourism trade with mexico in the long term these results provide evidence contradicting the j curve theory supporting the postulations of the ml condition theoretical and policy implications are discussed within the realms of j curve theory marshall lerner ml condition international trade and tourism

the craft of labormetrics using a wide array of examples from the literature and from original estimates the author examines the pitfalls that make good empirical research in labor economics at least as much craft as statistical technique among the subjects discussed are the appropriateness and cleanliness of data problems of extreme observations the validity of attempts to produce exogeneity using instrumental variables natural experiments and structural models and the treatment of selectivity and unobservable individual effects the author stresses the importance of testing empirical results to ensure that they make sense and of presenting them clearly and economically

capital movements intersectoral resource shifts and the trade balance abstract in this paper i consider the interactions between the internal structure of the economy and its external balance in an intertemporal set up with perfect foresight a simple pattern emerges current account deficits are associated with depreciating real exchange rates the incorporation of real investments and government spendings change this pattern in a systematic way depending on factor intensities the composition of government spending and its timing

capital controls and fiscal policy in the world economy an intertemporal utility maximization framework is employed to model a world economy with capital controls the effects of fiscal policy in such an environment are examined several results emerge concerning the international transmission of fiscal policy under capital controls and the nature of comovements in macro economic aggregates such as output employment consumption and investment some of the paper s other results concern the implications of capital controls for ricardian equivalence the role of financing decisions in the international transmission process under capital controls and the effect of capital controls on the magnitude of fiscal induced fluctuations throughout the world economy contr6les des mouvements de capitaux et politique fiscale dans l conomie mondiale les auteurs utilisent une approche par la maximisation intertemporelle de l utilite pour modeliser une economie mondiale dans laquelle des controles sur les mouvements de capitaux existent ils examinent les effets de la politique fiscale dans un tel contexte on tire de ces analyses plusieurs resultats quant i la transmission internationale des effets de la politique fiscale et quant aux mouvements lies de certains agregats economiques comme les niveaux de production d emploi de consommation et d investissement certains autres resultats de cette analyse ont trait aux implications des controles des mouvements de capitaux sur l1 quivalence ricardienne au role des decisions de financement dans le processus international de transmission quand il y a controle des mouvements de capitaux et aux effets des controles sur les mouvements de capitaux sur la magnitude des fluctuations induites a travers l economie mondiale par la politique fiscale helpful comments from two anonymous referees are gratefully acknowledged discussion in workshops held at ucla duke university iowa state university queen s university vanderbilt university vpi and the university of western ontario has also been useful canadian journal of economics revue canadienine d economique xviii no 4 november novembre 1985 printed in canada imprime au canada 0008 4085 85 743 65 1 50 canadian economics association this content downloaded from 207 46 13 129 on mon 27 jun 2016 05 25 03 utc all use subject to http about jstor org terms 744 jeremy greenwood and kent p kimbrough

the j curve evidence from commodity trade between uk and china in testing the short run j curve effect and the long run effects of currency depreciation on the trade balance many researchers have used either trade data between one country and the rest of the world or between one country and another trading partner both groups are said to suffer from aggregation bias to reduce the bias in this article we consider trade data between one country the us and her trading partner china disaggregated by commodity we use imports and exports of 88 industries 2 digit and 3 digit classifications and cointegration analysis to show that the trade balance of at least 34 of the industries react favourably to real depreciation of the dollar the j curve effect is detected in 22 industries furthermore most of these industries that are sensitive to currency depreciation are durable commodity groupings

exchange rate sensitivity of the demand for money in developing countries there is consensus among researches that under the present floating exchange rate system although developing countries peg their exchange rate to a major currency they cannot avoid fluctuation in their effective exchange rates as long as major currencies fluctuate against one another few authors have investigated the effects of changes in effective exchange rates of developing countries on their imports exports trade balance demand for international reserves inflation etc in this paper we try to inestigate the effects of effective exchange rates of developing countries on their demand for money previous authors who have estimated a money demand function inclusive of an exchange rate variable bilateral or effective have restricted themselves to industrial countries only by using quarterly data over the 1973 85 period it is shown that in most developing countries while the short run effcts of depreciation could be in either direction its long run effects are negative indicating that deprecia

nominal and real effective exchange rates of middle eastern countries and their trade performance indexes of real and nominal effective exchange rates that are published by the imf are mostly for industrial countries none of the middle eastern countries have received any attention on this regard this paper tries to close the gap by constructing such indexes for 11 middle eastern countries over 1971 i 1994 iv period as an application long run response of their trade balance to devaluation is also investigated

commodity trade between pakistan and the us is there evidence of the j curve abstracta few studies that have attempted to estimate the short run j curve and long run impact of exchange rate depreciation on pakistan s trade balance are either based on aggregate trade data between pakistan and the rest of the world or between pakistan and her bilateral trading partners the findings are mixed at best considering the trade balance between pakistan and the us as one of its major partners no significant effects have been discovered suspecting that the trade flows between the two countries could suffer from another aggregation bias we disaggregate their trade flows by commodity and consider the trade balance of 45 industries that trade between the two countries we find significant short run effects of currency depreciation on the trade balance of 17 industries the short run effects last into the long run in 15 cases the largest industry that account for more than 10 of the trade seems to benefit from real depreciation in the long run

asymmetric response of the us india trade balance to exchange rate changes evidence from 68 industries the relationship between the trade balance and the exchange rate continues to attract attention by international economists and has entered into new territory mostly due to advances in econometric methods the introduction of asymmetric error correction modelling and asymmetric cointegration using the nonlinear ardl approach of shin et al festschrift in honor of peter schmidt econometric methods and applications springer 2014 281 as compared to the symmetric and linear ardl approach of pesaran et al journal of applied econometrics 2001 16 289 has led us in a new direction to discover relatively better results we apply these methods to the bilateral trade balance model of each of the 68 industries that trade between india and the usa the nonlinear approach not only provides more support to the j curve effect but also yields support in favour of short run and long run asymmetric effects of exchange rate changes in most of the industries

fiscal dependence on trade taxes and trade policy reform the article focuses on fiscal implications of structural adjustment loans sals from an a priori standpoint and by reference to the experience of five countries three of these countries have had revenue enhancement after trade policy reforms and the other two cases experienced revenue depletion the central point which emerges from the study is that it is not clear that trade liberalisation leads to fiscal enhancement or fiscal depletion both a priori the orising and country analyses demonstrate that a range of outcomes is possible depending upon initial conditions and the components of any reform package

impulse response analysis and orcutt s hypothesis in trade evidence from developing countries orcutt s hypothesis in international economics implies that trade flows respond to exchange rate changes faster than to changes in relative prices most previous studies used import and export demand models and tested the hypothesis by imposing and comparing lag lengths on the exchange rate and relative prices one recent study however employed impulse response of trade flows to one sd shock to the nominal exchange rate and one sd shock to relative prices and tested the orcutt s hypothesis for several industrial countries in this article we follow this study and test the hypothesis for six developing countries using impulse response analysis like the other study for industrial countries we do not find much support for the hypothesis

a comparison of alternative models for the demand for medical care we have tested alternative models of the demand for medical care using experimental data the estimated response of demand to insurance plan is sensitive to the model used we therefore use a split sample analysis and find that a model that more closely approximates distributional assumptions and uses a nonparametric retransformation factor performs better in terms of mean squared forecast error simpler models are inferior either because they are not robust to outliers e g anova anocova or because they are inconsistent when strong distributional assumptions are violated e g a two parameter box cox transformation

on fiscal deficits the real exchange rate and the world rate of interest we use a full general equilibrium two country two period model with perfect capital markets and intertemporal optimization and perfect foresight underlying private consumer behaviour in both countries to analyse effects of pure fiscal policy we demonstrate that higher government budget deficits in one country caused by a cut in commodity taxes today balanced by an equal present value increase tomorrow will not be offset one for one by higher private savings because of pure substitution effects triggered by the change in the intertemporal terms of trade the tax change causes the country with the increased government deficit will therefore run a larger current account deficit which in turn unambiguously leads to higher world real interest rates whether a real appreciation results in the country with the higher deficit is shown to depend on the metzler condition for an undereffected transfer if we spend more on our goods than they spend on our goods on the margin government deficits will lead to an appreciation of the exchange rate of the country with the government deficit and vice versa

the j curve malaysia versus her major trading partners currency depreciation is said to worsen the trade balance before improving it hence the j curve phenomenon since introduction of cointegration and error correction modelling researchers have tried to distinguish the short run effects of currency depreciation from its long run effects a few studies that have investigated the experience of malaysia have relied upon aggregate trade data and have found no strong support for a significant relation between the real value of the ringgit and the malaysian trade balance in this article we disaggregate the data by country and consider malaysia s bilateral trade balance with her 14 largest trading partners using bound testing approach to cointegration and error correction modelling we provide some support for the j curve hypothesis

estimation of j curves united states and canada delayed reactions to exchange rate changes in trade on current account balances are known to exist in both the united states and canada a model has been constructed to estimate relative price effects for trade with major partners in order to determine the quantitative magnitudes and relevant time delays for both countries adjustments in trade accounts there is a distinct tendency for balances to worsen when exchange depreciation first occurs and then to improve after several quarters have passed there is also a tendency for the balances to worsen again the u s and canadian time profiles of adjustment are found to be similar

risk equalization and voluntary deductibles a complex interaction the presence of voluntary deductibles in the swiss and dutch mandatory health insurance has important implications for the respective risk equalization systems in a theoretical analysis we discuss the consequences of equalizing three types of expenditures the net claims that are reimbursed by the insurer the out of pocket expenditures and the expenditure savings due to moral hazard reduction equalizing only the net claims as done in switzerland creates incentives for cream skimming and prevents insurers from incorporating out of pocket expenditures and moral hazard reductions into their premium structure in an empirical analysis we examine the effect of self selection and conclude that the swiss and dutch risk equalization systems do not fully adjust for differences in health status between those who choose a deductible and those who do not we discuss how this may lead to incentives for cream skimming and to a reduction of cross subsidies from healthy to unhealthy individuals compared to a situation without voluntary deductibles
