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

whom can we trust to run the fed theoretical support for the founders views abstract the federal reserve has been called a bizarre policymaking structure this paper documents and formalizes a historical argument that the fed s structure was a response to public conflict over inflation s redistributive powers the paper shows that in the face of conflict over redistributive inflation policy by majority can lead to policy that is worse even for the majority than obvious alternatives in balancing the interests for and against surprise inflation the fed s structure can lead to a better outcome

has the european monetary system led to more exports evidence from four european union countries abstract we attempt to investigate whether the exchange rate mechanism erm period has coincided with an increase in intra eu exports we conclude that this has not been the case but it is likely that the elimination of nominal exchange rate variability arising from a single currency will boost intra european union trade

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 rates and trade the case of irish exports to britain this paper examines the effect of changes in the punt sterling exchange rate on exports from ireland to britain the approach used here differs significantly from that used in most other studies in that the long run neutrality of the punt sterling exchange rate with regard to exports from ireland to britain is tested using a recently developed technique there is strong evidence that the exchange rate is neutral in the long run

exchange rate volatility and international trade a general equilibrium analysis abstract we analyze the relation between exchange rate volatility and the volume of international trade in a general equilibrium stochastic endowment economy with imperfect international commodity markets and treating both variables as endogenous even in the simplest model the sign of the relation depends on the source for the change in volatility for instance more volatility of the endowments and higher costs to international trade both boost exchange risk and lower welfare but the first increases the expected volume of trade while the second decreases trade note that even the inter equilibria relation between trade and welfare is ambiguous

exchange rate variation commodity price variation and the implications for international trade abstract a commonly cited disadvantage of floating exchange rates is that a fluctuating exchange rate reduces international trade when firm owners are risk averse risk averse firm owners are concerned with the variation in the real domestic currency price of the good they export or import this price variation depends on exchange rate variation but also on a good s foreign currency price variation domestic price level variation and the covariation between these three variables the empirical results presented here show that for many commodities floating exchange rates did not cause a significant increase in overall real domestic currency price variation

exchange rate effects on the volume and variability of trade flows abstract this paper investigates the effects of exchange rate uncertainty on the volume and variability of trade flows employing a signal extraction framework we show that the direction and magnitude of importers and exporters optimal trading activities depend upon the source of the uncertainty general microstructure shocks fundamental factors driving the exchange rate process or a noisy signal of policy innovations providing a rationale for the contradictory empirical evidence in the literature we also show that exchange rate uncertainty emanating from general microstructure shocks and the fundamental factors reduces the variability of trade flows while that related to a noisy signal of policy innovations increases variability

monetary and exchange rate arrangements for nafta abstract this paper considers the extent to which the north american free trade area nafta meets the criteria for a common currency area nafta is compared with the ec a regional grouping for which initial plans for a monetary union are already in place most of the anticipated benefits from a monetary union in the ec apply with equal force to nafta however because the underlying disturbances are more diverse across members of nafta the costs of abandoning the exchange rate instrument are likely to be higher this is particularly true when nafta is compared to the ec s continental core

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

adjustment costs and international trade dynamics abstract this paper develops a model of trader behavior that is characterized by quadratic adjustment costs imperfect competition and rational expectations the model is fitted to data on aggregate trade flows between the united states and three of its largest trading partners tests against alternative specifications confirm the importance of imperfect competition and adjustment costs the hypothesis of rational expectations cannot be rejected the estimated price elasticities of trade flows are generally in the range reported by previous researchers but the activity elasticities are significantly higher

hyteresis in import prices the beachhead effect this paper shows that temporary real exchange rate fluctuations can have persistent hysteretic effects on trade specifically when market entry costs are sunk sufficiently large exchange rate shocks alter domestic market structure and thereby induce hysteresis this simple result has strong implications for exchange rate theory t rade policy and estimation of trade equations empirical evidence su ggests that the recent dollar overvaluation induced hysteresis in u s import prices namely the aggregate pass through equation of exchange rates to import prices shifted in the 1980s the shift s nature and timing is broadly consistent with the hysteresis hypothesis copyright 1988 by american economic association

on the effectiveness of capital controls the experience of colombia during the 1990s abstract this paper analyzes the effectiveness of capital controls in colombia the evidence presented points towards a relative inability of the measures adopted to reduce the level of capital inflows nonetheless the evidence suggests that non remunerated deposits have been successful in inducing a recomposition of foreign liabilities in favor of long term maturities it is likely that this is a positive result as it has made the country less vulnerable to a reversal in capital flows in this sense controls may be viewed as an effective way of internalizing the negative externality imposed by short term maturities

does china really lose from rmb revaluation evidence from some export industries this study attempts to examine the impacts of real exchange rate rer misalignment on china s export performance using the sur methodology coupled with disaggregate panel export data it shows that china s export sector may not necessarily lose from the central government s decision to revalue its rmb against the us dollar because the negative impact of the rer appreciation on chinese exports may be diluted by the positive impacts attributing to a reduction in the rer misalignment

hypercongestion in production correspondences an empirical exploration this empirical contribution reviews the rather limited existing literature measuring congestion in production it first compares current ways to measure congestion using nonparametric specifications of technologies in particular it focuses on the magnitude and incidence of the congestion detected in empirical studies using traditional radial efficiency measures thereafter it shows the limitations of this radial measurement and how alternative measurement schemes may reveal higher amounts of congestion then the new more general methodology of measuring s congestion is presented in particular we first present a numerical example to illustrate the way the s disposable technologies allow to capture more extreme forms of congestion by setting empirically determined upper bounds to the wasting of inputs then an empirical illustration is presented based on an existing sample of data a final section concludes

why is it so difficult to find an effect of exchange rate risk on trade abstract it is commonly argued that exchange rate risk hampers international trade however the large literature on this subject has not yet provided conclusive evidence this paper analyzes why it is so difficult to obtain a clear answer from time series analyses we use data on bilateral aggregate u s exports to the other g7 countries the results show that as far as the exchange rate is concerned export decisions are mostly affected by the probability distribution of the about one year ahead rate the riskiness of the exchange rate at such a long horizon appears fairly constant over time with only short term fluctuations this makes it difficult to discover the true effect of exchange rate risk on trade from the time series data that are typically available

currency hedging and goods trade abstract a puzzle in empirical international finance is the difficulty in finding a large and negative effect of exchange rate volatility on international trade a common explanation is the availability of hedging instruments this paper examines the empirical validity of this explanation using data on over 1000 country pairs which countries have currency hedging instruments is not perfectly observable this paper deals with the problem by specifying an endogenous regime switching regression there are two main findings first there is no evidence in the data to support the validity of the hedging hypothesis second for country pairs with large trade potential exchange rate volatility deters goods trade to an extent much larger than that typically has been documented in the literature without using the switching regression specification

exchange rate volatility and international trade the purpose of this note is to show that a positive effect of exchange rate volatility on export production has a theoretical basis the key to this claim is that as the exchange rate volatility increases so does the value of the real option to export to the world market higher volatility increases the potential gains from trade this may explain part of the mixed empirical findings regarding the effects of exchange rate risk on international trade

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

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

surface mining of coal efficiency of us interior mines in this paper the relative efficiency in surface mining of us interior coal is investigated a nonparmetric non stochasitic method is applied to 186 observations and esch firm s efficiency is calculated relative to the piecewise llinesr frontier technology in adition three sources of inefficiency are identified namely scale congestion and purely technical inefficiency the outcome of the study shows among other things that on the average captive mines are more efficient than non captive mines and that unionized mines are more efficient than non unionized mines

the effects of exchange rate variability on international trade a meta regression analysis the trade effects of exchange rate variability have been an issue in international economics for the past 30 years the contribution of this article is to apply meta regression analysis mra to the empirical literature on average exchange rate variability exerts a negative effect on international trade yet mra confirms the view that this result is highly conditional by identifying factors that help to explain why estimated trade effects vary from significantly negative to significantly positive mra evidence on the pronounced heterogeneity of the empirical findings may be instructive for policy first by establishing that average trade effects are not sufficiently robust to generalize across countries and second by suggesting the importance of hedging opportunities hence of financial development for trade promotion for the practice of mra we make a case for checking the robustness of results with respect to estimation technique model specification and sample

exchange rate variability and the flow of international trade abstract this study uses a garch generalized autoregressive conditional heteroskedasticity model to test if real exchange rate volatility has an adverse effect on the value of u s imports from canada we find that exchange rate uncertainty has a negative and statistically significant affect on trade flows
