purchasing power parity based on effective exchange rate and cointegration 25 ldcs experience with its absolute formulation abstract with the development of cointegration technique the purchasing power parity ppp theory has received renewed attention most studies have tested the theory by using data from developed countries dcs and some high inflation less developed countries ldcs they have mostly rejected its empirical validity in this paper we use the concept of effective exchange rate and quarterly data over 1973 1988 to examine the experience of 25 ldcs for most countries we found little empirical support for the ppp

capital utilization and capital accumulation theory and evidence a firm may acquire additional capital input by purchasing new capital or by increasing the utilization of its current capital the margin between capital accumulation and capital utilization is studied in a model of dynamic factor demand where the firm chooses capital labour and their rates of utilization a direct measure of capital utilization the work week of capital is incorporated into the theory and estimates the estimates imply that capital stock is costly to adjust while the work week of capital is essentially costless to adjust the estimated response of the capital stock to changes in its price and in the required rate of return is more rapid than found in other estimates

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

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

empirical investigation of one opec country s successful non oil export performance abstract this study examines indonesian non oil export success between 1975 and 1994 with a focus on the role of exchange rate management and trade policy in export performance across sectors to examine the link between export quantity and changes in policy i estimate structural export supply functions that are derived from utility and profit maximization behavior the results indicate that non oil exporters respond positively to improved price incentives including exchange rate devaluation with the strongest impact in textiles garments and sawnwood the study offers a richer description than previous work of the relationship between price incentives and export performance

a cost function analysis of import demand for nigeria the article uses a translog cost function to examine the substitution relations among capital labour and imports the results show that capital has a substitute relation with domestic labour and import however labour and import have complementary relationship the implication of this finding is that liberalization policies if pursued vigorously could impart positively on the demand for labour in addition it suggests that economic growth could be enhanced through trade liberalization

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

exchange rate volatility and japan u s commodity trade an asymmetry analysis exchange rate volatility is said to affect trade flows in either direction when increased volatility is separated from decreased volatility asymmetric analysis reveals even more support for the fact that both increased volatility and decreased volatility affect trade flows in either direction we add to this new literature by considering 57 industries that trade between japan and the us in addition to providing evidence of asymmetric response of their trade flows to a measure of exchange rate volatility our approach identifies industries that could benefit from increased exchange rate volatility and those that could be hurt similarly we identify industries that could benefit from decreased volatility and those that could be hurt the overall conclusion is the adverse effects of dollar yen volatility on the trade between the two countries

the econometrics of kinked budget constraints in the last several years a branch of applied econometrics has developed which is devoted to the development of techniques for the estimation of demand and other functions when the budget constraint is piecewise linear or kinky that is when the constraint consists of a number of segments joined together at kink points such constraints most frequently arise from government tax and transfer programs for example the federal income tax imposes a piecewise linear schedule by the use of constant marginal tax rates within brackets a problem analyzed by hausman 1981 the payroll tax in the social security system likewise generates a kinked schedule inasmuch as the marginal tax rate on earnings is zero above a certain earnings maximum federal and state transfer programs for the poor result in piecewise linear constraints because transfer benefits are taxed in the sense of a negative income tax as income rises and because that tax rate falls to zero at the kink point where an individual or family loses eligibility for the benefit altogether many government transfer programs impose additional nonlinearities by altering this tax rate by discrete amounts over the range of positive benefits as well but kinked constraints sometimes arise in nongovernment contexts a well known example being the block pricing schedule commonly set by utilities and volume discounting in general kinked budget constraints create two difficulties that have several interesting facets one difficulty is that changes in tax and transfer schedules can have unexpected effects that can be exactly the opposite in sign to those expected from economic theory examples of this phenomenon are given below the second difficulty that with which this paper is mostly concerned relates to the implications of kinked budget

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

scissors or horizon neoclassical debates about returns to scale costs and long run supply 1926 1942 modem treatment of long run u shaped cost curves developed from reactions to sraffa s criticisms of marshall he argued that internal dis economies were incompatible with partialequilibrium analysis under perfect competition pigou concurred and drew l shaped cost curves viner realized that this made firm size indeterminate and industry output volatile using austin and joan robinson s analyses stigler justified rising costs supply determinacy and stability by irrational entrepreneurs enduring coordination failure and by factor price changes we conclude that consistency requires constant costs but firm employment output and factor incomes remain theoretically indeterminate it becomes likely that large firms will undermine perfect competition

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

long run price elasticities and the marshall lerner condition revisited abstract in estimating trade elasticities most previous researchers employed nonstationary data and ols or 2sls method with new developments in the literature this paper uses stationary data and johansen s cointegration analysis to provide new trade elasticities for almost 30 countries

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

same currency different strategies the role of the exchange rate in shaping european agri food exports abstractthis article uses a nonlinear autoregressive distributed lag nadrl model introduced by shin yu and greenwood nimmo 2014 to assess the role that the exchange rate plays in shaping european agri food exports after the introduction of the euro although the 10 countries of this study share the same currency and thus a single nominal exchange rate with the us cross country discrepancies of exports reactions to exchange rate changes are evident moreover i find that exchange rate changes influence exports asymmetrically in the long run euro appreciations are harmful to a lesser extent than euro depreciations are beneficial for european agri food exports the magnitude of this effect is country specific and varies considerably between individual exporting countries exported quantities are less affected by exchange rate fluctuations than export values which is in line with local currency price stabilization strategies of the exporters this finding is interpreted as a sign of an incomplete

exploring the interaction between stock price index and exchange rates an asymmetric threshold approach this article examines the impact of stock market news on the foreign exchange markets of usa canada and uk employing an innovative extension of the asymmetric threshold model of apergis and miller 2006 under this framework we can disentangle the reaction of foreign exchange market to bad or good news and small or large news of stock returns our comprehensive daily data set spans the period from january 1990 to june 2014 using a cointegration and error correction model we document the existence of a causal relationship between stock market and foreign exchange markets most interestingly our results derived from the asymmetric threshold model confirm that the relationship between stock and foreign exchange markets is sensitive to short term good or bad news and short term small or large news our findings entail significant implications for policymakers governments risk managers and international investors

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

the theoretical developments initiated by haberler but named for pigou do not provide sufficient grounds for rejecting keynes s key theoretical proposition this paper examines a claim made in the introduction to milton friedman s presidential address to the american economic association and that is now taken for granted in orthodox economics according to friedman the theoretical developments initiated by haberler but named for pigou provide sufficient grounds for rejecting keynes s key theoretical proposition and the economics of keynes in its entirety the problem with this claim is that it turns out given the scrutiny that it clearly deserves to be false the theoretical developments initiated by haberler but named for pigou do not provide sufficient grounds for rejecting keynes s key theoretical proposition and thus the economics of keynes as a whole there is no legitimate rationale for believing in other words even in a world of flexible prices that the system will tend naturally toward a position of equilibrium at full employment

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

non adherence to a low fat diet an economic perspective abstract despite bearing increased risk of suffering a heart attack failure to adhere to a low fat dietary regimen is wide spread the paper applies an expected utility maximization model to inquire into the individual s decision to deviate from a prescribed low fat diet offering an economic explanation for excess high fat consumption the implications of self protection against the risk of dying from an attack are further examined the analysis reveals that self protection and dietary adherence can be complements suggesting that public health policy may help reduce both the risk of an attack and the risk of dying from an attack through providing incentives for self protection

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

kalman filter approach to estimate the demand for international reserves a few studies have provided empirical support for the fact that the demand for international reserves experienced structural instability in 1973 and 1979 due to a change in exchange rate system and oil price shocks thus under the current managed float due to exchange rate and oil price fluctuations coefficient estimates could be time dependent after showing that indeed estimated coefficients are time dependent the kalman filter estimation method is employed and the reserve demand function for 19 industrial countries estimated the kalman filter approach incorporates the time varying properties of coefficients estimates

consumption asymmetry and the stock market empirical evidence abstract this paper examines whether u s stock market value affects consumption asymmetrically using cointegration and error correction methodology the results confirm that stock market value asymmetrically affects real per capita consumption negative news affects consumption more than positive news

will developing country debt forgiveness increase agricultural trade abstract latin american countries are important customers in international agricultural trade however between 1981 and 1987 u s agricultural exports to these countries declined by almost 50 one explanation for the above decrease is the change in financial conditions facing many countries in this region outstanding debt in the latin american countries continued to rise through the 1980 s reaching over 120 billion for brazil and mexico by 1987 in this paper we develop an import model which considers the effect of the debt crisis on the ability of developing countries to purchase agricultural commodities in world markets we estimate the model for four countries mexico brazil chile and venezuela the estimated results are used in a simulation model to obtain the effects of a 50 debt forgiveness scenario results indicate only a modest improvement in agricultural imports of the four latin american countries considered in this study these four countries would expand agricultural imports by 400 million per annum given the debt reduction

asymmetric j curve evidence from industry trade between u s and u k previous research that assessed the impact of exchange rate changes on the trade balance between the u s and u k assumed the effects are symmetric in this paper we add to the literature on the

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

is there a j curve abstract if the response of the value of the trade balance to movements in the real exchange rate is described by a j curve then a real depreciation initially worsens a balance of trade deficit only improving it over time this paper investigates whether a j curve can be detected in the last twenty five years of american data no statistically reliable evidence of a stable j curve is detected the model is checked extensively to support this finding

trade liberalisation the peso and mexico s commodity trade flows with the united states abstract we assess the effects of real peso devaluations as well as the effects of gatt and nafta on mexico s in payments and out payments with the united states for 102 industries we find that relatively few trade flows are sensitive to changes in the real exchange rate probably due to production sharing and intra industry trade but devaluations affect mexican imports more than exports trade liberalisation has had a larger impact particularly on imports of intermediate goods and exports of certain manufactures many affected export industries are ones that have previously been shown to have economies of scale

demand and supply factors in the determination of nie exports a simultaneous error correction model for hong kong a comment v a muscatelli t g srinivasan and d vines 1992 purported to refute j riedel s 1988 finding that hong kong is a small price taking country in world markets this comment shows however that muscatelli srinivasan and vines s results are due entirely to an unjustifiable restriction they imposed on the estimated export demand equation and not the result of using a superior estimation technique as they asserted copyright 1994 by royal economic society

business cycles in the united kingdom facts and fictions this paper documents the statistical properties of contemporary business fluctuations in the united kingdom we study the period 1956 90 using quarterly detrended data on key aggregate variables we compute selected moments of the data compare our results with those for the united states and rigorously test for dynamic instabilities our findings confirm the existence of substantive cyclical regularities both across countries and across time some notable cross country differences are also identified conclusions about stability are shown to be potentially sensitive to the method of testing in general cross correlations are appreciably more stable than standard deviations

effects of exchange rate flexibility on the demand for international reserves abstract we incorporate a measure of exchange rate flexibility into the standard reserve demand equation and present empirical results for the 1976 1985 period which are consistent with the work of officer 1976 and frenkel and jovanovic 1981 indicating the existence of economies of scale and the demand for reserves

allocatable fixed inputs and jointness in agricultural production implications for economic modeling allocatable fixed inputs such as land are a potentially important source of jointness in agriculture as with other causes of jointness they necessitate multiple product systems for modeling product supply and input demand in other important ways however their analytical implications are very different from other causes of jointness model specification differs demand functions for the quantities of each input used in the production of individual commodities can be derived if a primal approach is used but such allocation equations cannot in general be identified from a dual specification available allocation data are not even useful in such dual estimations

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

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

determinants of the demand for thailand s exports of tourism we investigate the effects of world income and the relative price of tourism in thailand on thailand s exports of tourism in contrast to previous studies we test for stationarity and cointegration of the variables of the model we find that the variables are not stationary in level form but they are cointegrated our estimate of the relative price elasticity of demand for thailand s exports of tourism is 1 199 in the short run and 0 891 in the long run the corresponding estimates for the income elasticity of demand are 1 926 and 2 342 respectively however only the short run price elasticity of demand is significantly different from zero

from real estate to consumption the role of credit markets in the usa the aim of this article is to test whether the credit market conditions affect the strength of transmission of real estate wealth effects on household consumption in the us economy although many different works have dealt with the analysis of the existence of a real estate wealth effect most of them as a reaction to the dramatic increase of housing prices in several oecd countries there are only few papers analysing whether the consumption response depends on the positive or negative sign of the wealth shock and as far as we know none of them takes the effects of credit market conditions on that asymmetric response into account this article tries to fill the existing gap in the literature on this matter from an econometric perspective we estimate the asymmetries in the consumption response within the momentum threshold autoregressive model m tar proposed by enders and siklos 2001 but following stevans 2004 it is applied to a multivariate framework the main results show that the credit mar

effects of exchange rate variability on inflation variability abstract previous studies have postulated that there exists a positive relationship between the rate of inflation and its variability they have shown that a high inflation rate contributes to inflation variability in this paper we argue that with the current floating exchange rate system exchange rate variability is another factor contributing to inflation variability after incorporating a measure of exchange rate variability into a simple model used by previous authors we estimate our model using cross country data from 20 developed and 76 less developed countries the cross sectional regression results support our conjecture

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

impact of exchange rate uncertainty on trade flows evidence from commodity trade between the united states and the united kingdom previous studies that investigated the impact of exchange rate volatility on the trade flows employed aggregate trade data and standard estimation techniques they provided mixed results in this paper we use disaggregated import and export data for 177 commodities traded between the united states and the united kingdom to investigate whether volatility of the real bilateral dollar pound exchange rate has any detrimental effect on trade flows at the commodity level additionally we employ the bounds testing approach to cointegration and error correction modelling that is suitable for the models used mostly because it does not require pre unit root testing and variables in the model could be stationary non stationary or a combination of the two in most trade flow models estimated we found a negative effect of exchange rate volatility on commodity trade

impact of exchange rate uncertainty on commodity trade between us and sweden previous studies that investigated the effects of exchange rate uncertainty on the trade flows of sweden employed aggregate trade data either between sweden and the rest of the world or at bilateral level between sweden and her major trading partners in this article we disaggregate the trade data and employ the import and export data from 87 industries that trade between sweden and the us we find that exchange rate volatility has significant short run effects on the trade flows between the two countries in almost two third of the industries however the short run effects are translated into the long run effects in one third of the cases furthermore the real depreciation of krona against the dollar was found to have favourable effects on the overall trade balance between the two countries

junk food home cooking physical activity and obesity the effect of the fat tax and the thin subsidy abstract in an effort to reduce the growing prevalence of obesity a tax on junk foods known as fat tax has been proposed the revenue from which could be used to finance a thin subsidy for healthy foods or exercising equipment the present paper addresses the fat tax and thin subsidy within a food intake rational choice model assuming that healthy meals are cooked at home with purchased ingredients and time input the paper examines the effects on obesity of a tax on junk food meals and a subsidy to cooking ingredients distinguishing between a weight conscious and a non weight conscious individual and between a weight conscious individual who is physically active and physically inactive the results show that for a non weight conscious individual a fat tax will unambiguously reduce obesity whereas a thin subsidy may increase obesity however for a weight conscious individual particularly one who is physically active even a fat tax may increase obesity as it may reduce not just the consumption of junk food but also the time devoted to physical activity the paper explores conditions under which obesity will rise fall or remain intact following the introduction of a fat tax or a thin subsidy

trade flows relative prices and effective exchange rates a var on ethiopian data the dynamic response of trade flows to price and effective exchange rate changes is examined via var using quarerly data from ethiopia for the period 1973 i 1985 iv the results show one way granger causality running from prices and exchange rates to imports and exports without significant feedback imports and exports exhibit similar response patterns to unexpected changes in relative prices and exchange rates the responses of imports and exports are larger and the adjustment takes longer when relative prices rather than exchange rates caused a change in international prices in the long run changes in prices account for a larger percentage of the forecast error variances in imports and exports than exchange rate changes it is shown that devaluation may have an initial adverse effect on the trade balance

inflationary effects of changes in effective exchange rates ldcs experience the inflationary effects of devaluations in less developed countries is investigated using rate of change of effective exchange rates it is shown that for most countries in the sample devaluations or depreciations are inflationary during the current floating exchange rate system in addition to inflationary effects of depreciations excees money supply imported inflation and expectation are also identified as additional sources of inflation in less developed countries

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

asymmetric effects of interest rate changes the role of the consumption wealth channel this article examines the role of the consumption wealth channel in explaining asymmetric effects of monetary policy changes towards this end we draw upon available literature on the consumption function and behavioural finance to construct a framework for asymmetric effects of monetary policy caused by the impact of wealth changes on aggregate consumption we then employ data from the uk to examine the validity of the proposed framework in the context of a liberalized economy with easy access to consumer credit wealth reduction due to monetary tightening is expected to have weaker impact on spending than increase in wealth our results validate the above hypothesis

the us china trade imbalance will revaluing the rmb help much abstract the large us china trade imbalance is regularly blamed on the undervalued rmb using an estimated model of the trade balance we find that improvements in the trade balance are likely to be modest for plausible revaluations

myopia liquidity constraints and aggregate consumption a simple test this note conducts a simple test for myopia and liquidity constraints in aggregate u s consumption the test exploits the fact that under myopia consumption should be equally sensitive to predictable income declines and increases while under liquidity constraints consumption should be more sensitive to predictable income increases than to declines using quarterly postwar data the author shows that aggregate consumption is in fact more sensitive to predictable income declines than increases this perverse asymmetry is inconsistent with both myopia and liquidity constraints but is qualitatively consistent with recent theoretical work incorporating loss aversion into intertemporal preferences

stock market wealth and consumer spending martha starr mccluer this article investigates the effects of stock market wealth on consumer spending traditional macroeconometric models estimate that a dollar s increase in stock wealth boosts consumption by three to seven cents with the substantial 1990s rise in stock prices the nature and magnitude of this wealth effect have been much debated after describing the issues and previous research i present new evidence from a well known consumer survey the results are broadly consistent with life cycle saving and a modest wealth effect most stockholders reported no appreciable effect of stock prices on their saving or spending but many mentioned retirement saving in explaining their behavior jel e21 e30 d12 i introduction the relationship between stock market wealth and consumer spending has been a subject of long standing interest traditional macroeconometric models estimate that a dollar s increase in household wealth boosts consumer spending by three to seven cents per year such an effect is consistent with predictions from a simple life cycle model in which consumers spend more over their lifetimes in response to higher wealth however the stock market is known to play a role as a passive predictor of information thus it is also possible that stock prices simply lead aggregate economic activity without any short run change in spending induced by changes in wealth understanding the response of spending to changes in wealth is important for determining how stock market fluctuations affect the macroeconomy the question also bears directly on theories of saving behavior and on the issue of retirement preparedness by today s workers the experience of the past few years provides an interesting opportunity to revisit this issue stock prices increased substantially in the 1990s with the standard poor s 500 more than doubling from 1994 to 1997 and rising another 44 through 1999 at the same time stock ownership broadened considerably mostly through mutual funds and retirement accounts so that a large number of households likely experienced wealth gains the increase in wealth might be expected to boost consumer spending and lower the saving rate and indeed these trends occurred however it is hard to separate the influence of the wealth effect from other factors that also would have promoted spending such as strong income growth and favorable labor market conditions this article presents some new evidence on the response of spending to changes in wealth the data come from the michigan survey research center src survey of consumers an ongoing nationally representative survey of u s households in interviews conducted between july and september 1997 households owning stock were asked special questions about their spending and saving the questions covered a number of factors that may influence the effect of wealth on spending including the value and form of stockholdings stock price expectations concerns about retirement and perceptions of income uncertainty in brief the results are broadly consistent with life cycle saving and a modest wealth effect the vast majority of stockholders reported no appreciable effect of stock prices on their spending or saving but many mentioned retirement saving in explaining their behavior the next section reviews previous research on the relationship between stock market wealth and consumer spending the third section describes the data from the michigan survey and the fourth presents the results a final section summarizes and concludes ii background and previous research to frame the discussion it is useful to review how an unexpected increase in wealth would affect consumption in a simple lifecycle model this model though restrictive in its assumptions provides valuable intuition about the propensity to consume unexpected stock gains consequences of refinements to the model are discussed below

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

india s trade balance in the 1980s an econometric analysis the paper is an examination of india s trade balance in the 1980s the approach attempted is of examining the bilateral trade balances of india with nine trading partners from the non communist bloc the long run equilibrium relations are studied via two var models in johansen s multivariate cointegration framework five hypotheses of interest are singled out for attention the nominal and real exchange rates consistently emerge as important influences on the trade balance however as the exchange rates fail weak exogeneity tests policy implications are not clear cut

the effects of trade liberalization on imports in selected developing countries abstract this paper analyses the impact of the reduction of tariff and nontariff barriers on the imports of 22 selected developing countries utilizing dynamic panel data techniques domestic income and relative prices are found to be significant determinants of import growth in addition the results indicate that import duties reduce import growth but the effect varies according to the region and the type of trade policy regime existing in the country the results also show that the elimination of trade policy distortions has a strong positive impact on import growth finally it is found that income and price elasticities are higher as a result of trade policy reform

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

taiwan s exports and trade imbalance against us and japan an empirical analysis the persistence of the bilateral trade surplus between taiwan and the usa and the bilateral trade deficit between taiwan and japan despite the significant appreciation or depreciation of the nt dollar during the early 1980s to the mid 1990s renewed interest to seek explanations for these phenomena to assess the above proposition a polynomial distributed lag pdl method is imposed on the impact of changes in the real exchange rate on the bilateral trade structure particularly export demand and trade imbalance between taiwan the usa and japan from 1981 to 1998 the empirical findings show that 1 the real income factors have important effects on the real exports in both cases 2 the real exchange rates and the real imports are not major determinants of the export demand from taiwan to the usa but they do play an important role on the real exports from taiwan to japan 3 the real exchange rate has significant effect on the real trade surplus with the usa and on trade deficit with japan but the real

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

taiwan s exports and trade imbalance against us and japan an empirical investigation based on error correction model this study employs recent advances in time series analysis cointegration and error correction model to examine the long run and short run determinants of the exports and trade imbalance between the usa japan and taiwan the unit root tests reveal nonstationary in most of the variables the cointegration tests affirm positive the long run associations are between the exchange rate changes and the exports as well as the trade imbalance once these long run effects are accounted for it is found that there are evidences of short run relationship between these variables

the great crash and the onset of the great depression this paper argues that the collapse of stock prices in october 1929 generated temporary uncertainty about future income which led consumers to forgo purchases of durable goods that the great crash generated uncertainty is evidenced by the decline in surety expressed by contemporary forecasters that this uncertainty affected consumer behavior is shown by the fact that spending on consumer durables declined drastically in late 1929 while spending on perishable goods rose slightly this effect is confirmed by the fact that there is a significant negative relationship between stock market variability and the production of consumer durables in the prewar era

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

what makes you grab low carb beers what makes people choose low carbohydrate high protein food low carb food which is good for health but usually tastes bad using panel data on us beer consumption in which each consumption occasion is uniquely associated with various companion based consumption contexts and exposure levels to diet information we analyse the variations in consumers preferences for low carb food the results show that there exist considerable gender differences in the preference variation under peer pressure first single females behave in a way they dislike drinking low carb beer in front of friends spouses and significant others second male both married and single and married females pretend to choose low carb beer when accompanied by spouses or significant others finally the elasticity of demand for healthy food with respect to news articles about low carb diets is positive yet with substantial differences in the degree of elasticity across demographic groups

dynamic epidemiology and the market for vaccinations abstract the intent of this paper is to raise the question of how and when externalities can arise in the market for vaccinations static and dynamic models of such markets are developed and compared a special case in a continuous time dynamic framework is examined and is found to be efficient i e there is no externality this is in contrast to the results from the static formulation raising doubts about the suitability of a static approach these results indicate that the question of whether there are externalities in individual immunization decisions is more involved than is generally supposed

cap reform modelling supply response subject to the land set aside abstract this paper uses duality theory to develop a model of european community agriculture the model is used to investigate the impact of the land set aside provision of the recent package of reforms of the common agricultural policy we assume that producers chose output and variable input levels that maximize difference between revenue and variable cost by including first order conditions for the allocation of land across its uses we impose that the observed allocations are profit maximizing allocations to overcome the problem of incorporating many outputs into an estimable production structure we imposed a priori the restriction that the technology was weakly separable in major categories of outputs with this restriction it was possible to model production decisions in stages using consistent aggregates in the latter stages

exchange rate volatility and pakistan s exports to the developed world 1974 85 abstract the paper attempts to estimate the impact of exchange rate uncertainty on pakistan s exports to the developed world for 1974 85 discovering strong evidence to suggest that exports were adversely affected by the increased variability of its bilateral exchange rates unlike much of the recent evidence on developed countries however it is the variability in nominal rather than real exchange rates that is significant the computations also suggest the presence of strong third country effects

foreign exchange reserves and import demand evidence from latin america this paper investigates the impact of foreign reserves domestic real income and relative import prices on import demand for seven latin american countries we differentiate empirically between the short run and long run impact of reserves income and prices on imports the paper has three main results first we show that there exists a unique long run relationship among real imports real income relative import prices and real foreign exchange reserves for all seven countries second we find that increases in foreign exchange reserves exert a significant positive effect on import demand in both the long run and the short run in all countries however the economic impact of foreign exchange reserves is rather small finally we find that the long and short run impact of real domestic income on import demand is positive as well while the effect of relative prices is negative

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

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment

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

inequality and growth in the united states is there asymmetric response at the state level a previous study that tried to assess the impact of economic growth on income inequality in the u s used state level data and an ardl panel model to conclude that economic growth worsens income in

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

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

business cycle asymmetry a deeper look this paper distinguishes two types of asymmetry in business cycles deepness and steepness deepness is defined as the characteristic that troughs are further below trend than peaks are above most previous research has focused exclusively on steepness which refers to cycles in which contractions are steeper than expansions a test for deepness is proposed and applied to u s post war quarterly unemployment real gnp and industrial production evidence of deepness is found for unemployment and industrial production while the evidence for real gnp is weaker previous evidence of steepness in unemployment is confirmed

stock market wealth and consumption this paper explores the link between changes in the aggregate value of corporate stock and changes in consumer spending it presents data on the distribution of corporate stock ownership based on the 1998 survey of consumer finances it also uses time series evidence on the comovement of stock market wealth and various categories of consumer spending to calibrate the wealth effect it concludes that in the year after a change in stock market values consumer spending is likely to rise by between one and two cents for each dollar increase in the value of corporate stock

on the concavity of the consumption function at least since keynes 1935 many economists have had the intuition that the marginal propensity to consume out of wealth declines as wealth increases nonetheless standard perfect certainty and certainty equivalent versions of intertemporal optimizing models of consumption imply a marginal propensity to consume that is unrelated to the level of household wealth we show that adding income uncertainty to the standard optimization problem induces a concave consumption function in which as keynes suggested the marginal propensity to consume out of wealth or transitory income declines with the level of wealth
