nonlinear effects of exchange rate volatility on the volume of bilateral exports in this paper we investigate empirically the impact of exchange rate volatility on real international trade flows utilizing a 13 country data set of monthly bilateral real exports for 1980 1998 we compute one month ahead exchange rate volatility from the intra monthly variations in the exchange rate to better quantify this latent variable we find that the effect of exchange rate volatility on trade flows is nonlinear depending on its interaction with the importing country s volatility of economic activity and that it varies considerably over the set of country pairs considered copyright 2003 john wiley sons ltd

volatility and irish exports we analyse the impact of volatility per se on real exports for a small open economy concentrating on irish trade with the uk and the us an important element is that we take account of the time lag between the trade decision and the actual trade or payments taking place by using a flexible lag approach rather than adopt a single measure of risk we also adopt a spectrum of risk measures and detail varied size characteristics and statistical properties we find that the ambiguous results found to date may be due to not taking account of the timing effect which varies substantially depending on which volatility measure is used

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

on the specification of price in studies of consumer demand under block price scheduling using a new model formulation and data from a sample of colorado utilities we investigated the price specification controversy marginal price versus average revenue when estimating residential water demand the improved statistical fit using average

on the sensitivity of the volume and volatility of bilateral trade flows to exchange rate uncertainty we present an empirical investigation of the hypotheses that exchange rate uncertainty may have an impact on both the volume and variability of trade flows by considering a broad set of industrial countries bilateral real trade flows over the period 1980 1998 similar to the findings of earlier theoretical and empirical research our first set of results shows that the impact of exchange rate uncertainty on trade flows is indeterminate our second set of results provides new and novel findings that exchange rate uncertainty has a consistent positive and significant effect on the volatility of bilateral trade flows helping us better understand macroeconomic volatility jel f17 f31 c22

exchange rate volatility international trade and resource allocation a perspective on recent research abstract recent research on the effects of exchange rate volatility is discussed and directions for future research are explored the need to pay more attention to the effects of diversification and firms characteristic is emphasized it is suggested that while international risk has risen substantially since floating the differential between international and domestic risk may not this could help explain the failure of international trade to fall drastically and suggests that exchange rate volatility has been more a reflection than an independent cause of underlying instability

on the investment sensitivity of debt under uncertainty abstract we investigate the impact of debt on a panel of u s manufacturing firms capital investment behavior as the underlying firm specific and market level uncertainty changes our estimates show that the influence of leverage on capital investment may be stimulating or mitigating depending on the effects of uncertainty

the impact of exchange rate volatility on international trade reduced form estimates using the garch in mean model abstract in this paper we use a multivariate garch in mean model of the reduced form of multilateral exports to examine the relationship between nominal exchange rate volatility and export flows and prices the model imposes rationality on perceived exchange rate volatility unlike conventional two step strategies tests are performed for five industrialized countries over the post bretton woods era we find that the garch conditional variance has a statistically significant impact on the reduced form equations for all countries for most of the countries the magnitude of the effect is stronger for export prices than quantities in addition the estimated magnitude of the impact of volatility on exports is not robust to using the conventional estimation strategy jel f41 f31

central bank transparency and the volatility of exchange rates abstract we analyze the effect of monetary policy transparency on bilateral exchange rate volatility we test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010 we find strong evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility using interaction models we find that this effect is more pronounced for countries with a lower flexibility of goods prices a lower level of central bank conservatism and a higher interest rate sensitivity of money demand

uncertainty determinants of firm investment abstract we investigate the impact of measures of uncertainty on firms capital investment behavior using a panel of u s firms increases in firm specific and capm based measures have a significant negative effect on investment spending while market based uncertainty has a positive impact

the effects of macroeconomic stability on foreign trade an analysis for spain 1986 2000 two main factors underlie the rebirth of interest in the study of the influence of the real exchange rate on trade the reduction of its volatility and the current trend towards price stability the objective of this study is to analyse the effects of the process of nominal convergence required of the european member states for the fulfilment of monetary integration on foreign trade flows the case of spain which is especially interesting in this context is studied for the period 1986 to 2000 the results of estimating the aggregate functions of the export and import of goods shows how macroeconomic stability has altered the behaviour of trade with respect to the two basic determinants income and prices how it has caused a significant structural change in the real exchange rate and finally how it has laid the explanatory bases for transactions in the twenty first century with the single currency the euro

hard or soft pegs choice of exchange rate regime and trade in africa summary this paper revisits the link between fixed exchange rate regimes and trade in the context of africa s exchange rate arrangements differentiating the effects of hard pegs currency unions from conventional soft pegs using a novel dataset of exchange rate regime classification the paper augments the gravity model of bilateral trade flows with measures of currency unions and conventional pegged arrangements and benchmarks africa s experience against the rest of the world we find that in both samples currency unions and pegs increase trade vis a vis more flexible exchange rate arrangements through channels in addition to reduced exchange rate volatility however the effect is almost twice as large for africa in addition the trade generating effect of pegs is at least as large for africa as that of currency unions suggesting that pegs could present a viable option perhaps an alternative to currency unions to promote trade in the region

the co2 growth nexus revisited a nonparametric analysis for the g7 economies over nearly two centuries abstract using a long dataset and some recently popularized nonparametric econometric techniques this study revisits the nexus between economic growth and carbon dioxide co 2 emissions for the g7 countries over nearly two centuries the use of nonparametric modelling is warranted by the fact that long historical time series are often subject to structural breaks and other forms of nonlinearity over the course of time we employ nonparametric cointegration and causality tests along with the cross validated local linear regression analysis and validate the existence of the environmental kuznets curve in six of the g7 countries canada france germany italy u k and the u s and the only exception is japan our empirical analysis also finds co 2 emissions and economic growth to be cointegrated and closely interrelated in the granger sense our results are robust and highlight the nonlinear causal relationship between the two variables

international trade and exchange rate volatility for currencies with well developed forward markets several papers have investigated the conjectured negative relationship between trade and short term exchange rate volatility without being very successful a theoretical explanation for the empirical anomalies is provided by solving explicitly for the forward rate because importers and exporters are on opposite sides of the forward market so is their exposure towards exchange rate volatility moreover which trade flow benefits and which one loses from increased volatility is determined by the signs of the aggregate net foreign currency exposure and the aggregate measure of risk aversion

does real exchange rate volatility affect sectoral trade flows this article investigates empirically the effect of real exchange rate volatility on sectoral bilateral trade flows between the united states and its top 13 trading partners our investigation also considers those effects on trade flows that may arise through changes in income volatility and the interaction between income and exchange rate volatilities we provide evidence that i exchange rate volatility does not systematically affect sectoral trade flows ii income volatility has little impact on trade flows and iii the effect of the interaction term on trade flows is opposite that of exchange rate volatility dampening its impact on trade flows

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

the effects of real exchange rate risk on international trade abstract by assuming real profit maximization and uncertain prices as well as exchange rates we conclude that it is uncertain percentage changes in the real exchange rate that are risky in international trade empirical estimation of fourteen bilateral trade flows among industrialized countries finds a significant negative effect on trade quantity from such risk in a number of these cases the expectation variable has a positive effect in a larger number of cases significant price effects from the expectation variable are fewer and from risk are negligible

measuring and analysing the effects of short term volatility in real exchange rates this paper examines short term volatility in the real effective exchange rates of industrial countries and its impact on their imports it yields three conclusions first volatility has not diminished as markets have gained experience with floating exchange rates the trend appears to be in the opposite direction for some countries second exposure to short term volatility has differed among countries japan and sweden have experienced much more than most other industrial countries third volatility appears to depress the volume of international trade this third finding is consistent with results reported by cushman and by akhtar and hilton and challenges earlier findings by hooper and kohlhagen

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

are exports a monotonic function of exchange rate volatility evidence from disaggregated pork exports production and marketing lags in agri food supply chains often force agricultural producers and food processors to commit to output targets before prices and exchange rates are realized a theoretical model illustrates how the processor s degree of risk aversion and domestic sales may cause the relationship between volatility of the exchange rate and exports to be non monotonic the relationship between exchange rate volatility and quebec pork exports to the united states and japan is investigated using linear and non linear estimation methods the results support the hypothesis that the relationship between exports and volatility is non monotonic

comparing residential water demand estimates under decreasing and increasing block rates using household data using a new model formulation and data from a sample of colorado utilities we investigated the price specification controversy marginal price versus average revenue when estimating residential water demand the improved statistical fit using average

exchange rate volatility and international trading strategy abstract it is usually argued that an increase in exchange rate volatility reduces the volume of international trade as trading firms are risk averse this paper shows that exporting firms benefit under fairly general conditions from an increase in exchange rate volatility firms optimally adjust their export volumes to the level of the exchange rate exporting is an option which is exercised if profitable in addition the paper presents conditions under which the volume of international trade grows with exchange rate volatility

exchange rate shocks and trade a multivariate garch m approach abstract we build on the recent literature studying the effects of uncertainty on trade by introducing a model that combines a reduced form vector autoregression for the growth rates of exports foreign income and the real exchange rate rer with a multivariate garch model up to 12 lags of several conditional standard deviations are added to relevant mean equations and all parameters are estimated simultaneously using maximum likelihood thus allowing us to avoid two step procedures that are common in the literature using a large data set of both developed and emerging countries we find evidence that rer uncertainty negatively impacts trade for several less developed countries we also find that rer uncertainty tends to be associated with a real currency appreciation when we compute generalized impulse response functions to study the impacts of unexpected shocks to rer growth on export growth the results are typically asymmetric positive shocks generate substantial negative responses while unexpected depreciations produce relatively smaller positive responses especially in our developing country sample

exchange rate volatility and trade a semiparametric approach we use a gravity model to analyse the impact of exchange rate volatility on the volume of bilateral international trade semiparametric regression methods are applied to the pooled data for over 200 countries our results indicate that volatility affects trade negatively although at very high level of volatility the effect diminishes and eventually becomes statistically indistinguishable from zero countries apparently find avenues to mitigate the detrimental impact of exchange rate uncertainty when volatility attains very high levels these results help reconcile the contradictory findings often found in the literature on the impact of exchange rate uncertainty on trade volume

exchange rate volatility international trade and the value of exporting firms abstract increased exchange rate volatility positively affects the value of exporting firms via the price and volume impacts of exchange rates and also makes an exporting strategy more attractive relative to the direct investment investment in export production capacity could therefore be a positive function of exchange rate volatility firms would also be more willing to sustain losses i e to engage in dumping before they abandon their export markets the effect on the volume and value of trade is ambiguous

exchange rate volatility and exports a firm level analysis the relationship between real exports and exchange rate volatility is investigated using panel data analysis at the firm level results indicate that there is no negative or positive relationship between volatility and real exports in addition firm size and level of international activity do not influence the size and significance of the volatility effect on exports however there is some evidence that firms use import revenue to lower their exchange rate exposure

international financial volatility and commodity exports evidence from the thai agricultural sector using 1981 2006 data from the bank of thailand i estimate the effect of four measures of real exchange rate volatility on thai exports of five key agricultural commodities controlling for both the level of the real exchange rate and foreign incomes estimates of the effect of volatility on export volume are generally negative and often significant lending support to a range of theoretical models that predict such an effect no such relationship exists between lagged values of exchange rate volatility and agricultural production the range of results obtained using various measures of volatility suggests caution in comparing studies using different measures copyright 2010 oxford university press

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

evidence on the specification of price in the study of domestic water demand the development of lakefront property in northern wisconsin has prompted in several towns minimum frontage zoning stricter than the state standard such zoning generates an economic loss by constraining development development effect and an economic

exchange rate variability and the level of international trade abstract theoretical research has shown that under reasonable assumptions exchange rate variability ought to depress the level of trade this paper builds a theoretical model designed to exaggerate the negative effect of exchange rate variability on trade in order to calibrate an upper bound to the potential size of this effect numerical analysis demonstrates that exchange rate variability of the magnitude currently observed among industrial countries has an insignificant effect on the level of trade this result is robust with respect to a wide range of parameter values and with respect to reasonable extensions of the model

fiscal readjustments in the united states a nonlinear time series analysis we analyze the fiscal adjustment process in the united states using a multivariate threshold vector error regression model the shift from single equation to multivariate setting adds value both in terms of our economic understanding of the fiscal adjustment process and the forecasting performance of nonlinear models we find evidence that fiscal authorities intervene to reduce real per capita deficit only when it reaches a certain threshold and that fiscal adjustment takes place primarily by cutting government expenditure the results of out of sample density forecast and probability forecasts suggest that a shift from a univariate autoregressive model to a multivariate model improves forecast performance

uncertainty and export performance evidence from 18 countries we study a sample of nine developed and nine developing countries to evaluate the questions of how foreign income uncertainty and real exchange rate rer uncertainty impact international trade and how those impacts vary according to stage of development rer uncertainty has a negative and significant impact on export growth for six of the nine less developed countries in our sample while it has an insignificant effect for a majority of the developed countries in both groups foreign income uncertainty has a more pervasively significant and frequently larger influence on trade than does rer uncertainty

has exchange risk depressed international trade the impact of third country exchange risk abstract this paper argues that the effect of exchange risk on bilateral and aggregate trade flows should be analyzed by including the impact of third country exchange risk factors in addition to direct bilateral or multilateral risk after a theoretical examination of these effects us bilateral export flow to its six largest trading partners are analyzed empirically i find individuality and jointly significant third country risk effects in most cases in contrast to some recent bilateral efforts i find a steadily growing negative impact on trade flows from exchange risk during floating and in contrast to recent aggregate trade flow studies i conclude that there was no temporary decline in exchange risk during the late 1970s

elections exchange rates and reform in latin america abstract in this paper we study the link between real exchange rate rer depreciation and elections in latin america our contribution is threefold first we employ a statistical model that takes into account the pervasive conditional heteroskedasticity found in financial data and includes a wide range of macroeconomic variables as regressors second we test whether the wave of central bank reform that swept the region has had any effect on the existence or strength of the electoral cycle in exchange rates third we test an additional hypothesis namely that financial liberalization may also be an important variable explaining changes in electoral effects on the real exchange rate in a panel of 9 latin american countries with available macroeconomic data and a history of exogenous election dates we confirm the previous findings that real depreciation intensifies after elections even when modeling the significant conditional heteroskedasticity in these data we also show for the first time in the literature that post election exchange rates are significantly less predictable we go on to test whether central bank reform has influenced the way in which elections affect the rer in latin america if reform has been effective at reducing political manipulation of the exchange rate then any relationship we see between elections and the rer before central bank reform should be mitigated in the post reform era we find that the relationship disappears after reform and that post reform real exchange rates are also significantly less volatile finally we show that financial liberalization seems to have a stronger effect on the conditional variance of the rer than does central bank reform but reform has a stronger impact on the conditional mean
