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.     

U.S. bilateral trade balances and the dollar

U.S. bilateral export and import values with seven large trading partners are tested for real exchange rate effects over 1975–1985. The results suggest that dollar devaluation would have the most favorable impact on the U.S. trade balance in the case of Japan and the least favorable in the case of Canada.     

Cointegration Approach to Estimating Bilateral Trade Elasticities Between U.S. and Her Trading Partners

Almost all previous authors who estimated the trade elasticities relied upon aggregate trade data. To avoid the aggregation bias, this paper provides estimates of trade elasticities using bilateral data between the United States and her six largest trading partners. Application of cointegration analysis reveals that in many cases, bilateral trade elasticities are large enough to justify real depreciation of the dollar as a mean of improving U.S. trade balance.[F14]     

基于贸易收支数据的美国贸易逆差与美元汇率相互关系研究

通过选择美国与中国、日本、加拿大、英国和欧元区11国等美国主要贸易伙伴的双边贸易数据作为样本,研究美国的双边贸易逆差与美元汇率之间的关系.实证分析表明,美国对主要贸易伙伴国的双边贸易收支与美元汇率没有实质性联系.美国逼迫其它货币升值没有也不能缓解美国的贸易逆差问题,同样,美国逼迫人民币升值也不能缓解美中双边贸易失衡问题.     

Commodity trade between Pakistan and the US: is there evidence of the J-curve?

A 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.     

Exchange rate uncertainty and US bilateral fresh fruit and fresh vegetable trade: an application of the gravity model

In order to analyse the effect of exchange rate uncertainty, we apply an empirical gravity equation to two sets of US bilateral trade data: fresh fruit over the period 1976–1999 for a panel of 26 countries; and fresh vegetables over the period 1976–2006 for a panel of nine countries. Based on panel estimation methods, and using both a moving SD measure and the Perée and Steinherr (1989) measure of exchange rate uncertainty, the results show that US bilateral fresh fruit trade has been negatively affected by exchange rate uncertainty. We also find some evidence that the exchange rate between the US dollar and the currencies of Latin American trading partners accounts for most of the negative impact of exchange rate uncertainty on bilateral trade flows in fresh fruit. In contrast, when using panel estimation methods and both measures of exchange rate uncertainty, we find no statistically significant evidence for any negative effect of exchange rate uncertainty on US bilateral fresh vegetable trade. However, we do find a statistically significant negative effect for exchange rate uncertainty when we estimate a US export gravity equation for fresh vegetables using the same panel of countries.     

Bilateral J-curve between the UK vis-à-vis her major trading partners

Currency depreciation is said to worsen the trade balance first before resulting in an improvement, yielding a short-run pattern labelled the J-curve phenomenon. While early studies tested the J-curve by using aggregate trade data, a few recent studies have employed bilateral data, mostly between the US and her major trading partners. In this paper we extend the literature by considering the experience of the UK. We test the phenomenon between the UK and her twenty major trading partners by employing data over 1973Q1–2001Q3 period. In most instances, we find no support for the J-curve in the short-run. In the long run, only in five cases has the exchange rate had significant impact on the bilateral trade balance.     

US–Indonesia trade at commodity level and the role of the exchange rate

Previous studies that assessed the impact of currency depreciation on inpayments and outpayments of Indonesia with her major trading partners did not find much significant results, especially in the trade with the United States. We wonder whether insignificant link between the real rupiah-dollar rate and Indonesia’s inpayments and outpayments with the United States is due to aggregation bias. To answer this question, we disaggregate the trade flows between the two countries by commodity and consider the sensitivity of inpayments of 108 US exporting industries and outpayments of 32 US importing industries from Indonesia. We find that most industries respond to exchange rate changes in the short run. In the long run, however, 32 inpayments schedule and 17 outpayments schedule are significantly affected. A 1% real depreciation of the dollar was found to improve US trade balance by 1.8%.     

Choice of currency basket weights and its implications on trade balance

This paper seeks to find an optimal choice of currency basket weights for emerging economies that peg their currencies to a currency basket, and to examine the long-run relationship between the real exchange rates of a group of trading partners. A general equilibrium model is set up to establish an optimal set of currency basket weights, coupled with the choice of fiscal policy, to simultaneously stabilize trade balance and aggregate price level of an economy. This optimal set of weights is a weighted average of two sets of weights; each targets at one policy goal (stabilizing either balance of trade or aggregate price level) at a time. Empirical studies including vector autoregression (VAR) analysis and cointegration analysis on the long-run relationship between the Thai baht and the real exchange rates of its major trading partners are presented.     

Purchasing power parity and country characteristics: Evidence from panel data tests

We examine long-run purchasing power parity (PPP) using panel data methods to test for unit roots in US dollar real exchange rates of 84 countries. We find stronger evidence of PPP in countries more open to trade, closer to the United States, with lower inflation and moderate nominal exchange rate volatility, and with similar economic growth rates as the United States. We also show that PPP holds for panels of European and Latin American countries, but not for African and Asian countries. Our findings demonstrate that country characteristics can help explain both adherence to and deviations from long-run PPP.     

美中贸易收支与人民币汇率关系:实证分析

针对美中贸易收支与人民币汇率问题,经研究发现,汇率变动对贸易收支的影响是值得怀疑的,仅仅依靠人民币汇率变动是无法解决美中贸易逆差问题的。1994—2002年年度数据实证显示,美中贸易收支与人民币汇率(名义或实际汇率)之间没有稳定的关系;1998—2003年月度数据计量表明,美中贸易收支与人民币汇率之间没有长期稳定的协整关系。并且,依据美中两国月度统计数据计量的结论是相一致的。因此,“人民币升值论”或许更多的是基于政治而非经济因素,人民币汇率浮动并不能解决美中贸易逆差问题。     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

Time-varying regional integration of stock markets in Southeast Europe

In an attempt to assess the impact of currency depreciation on the trade balance, recent studies are employing disaggregated trade data to avoid aggregation bias. However, since import and export prices are not available at disaggregated level, recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate. This study explores the experience of Malaysia. Bilateral inpayments and outpayments models are estimated between Malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration. The results show that while real depreciation of the ringgit has short-run effects, in the long-run it increases Malaysia's inpayments from only five trading partners.     

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 BILATERAL J-CURVE: AUSTRALIA VERSUS HER 23 TRADING PARTNERS

Several studies have tested the J-curve phenomenon for Australia using non-stationary aggregate trade data and have provided mixed results. They not only suffer from the 'aggregation bias problem' but also from the 'spurious regression problem'. To overcome these problems, in this paper we investigate the short-run and the long-run effects of real depreciation of the Australian dollar on the trade balance between Australia and each of her 23 trading partners using quarterly data over the 1973–2001 period and recent advances in cointegration analysis. The results from the bound testing approach for cointegration and error-correction modeling does not provide much support for the J-curve phenomenon.     

Modeling nonlinear Granger causality between the oil price and U.S. dollar: A wavelet based approach

In this paper, we use a wavelet approach to study the linear and nonlinear Granger causality between the real oil price and the real effective U.S. Dollar exchange rate. Instead of analyzing the time series at their original level, as it is usually done, we first decompose the two macroeconomic variables at various scales of resolution using wavelet decomposition and then we study the relationships among the decomposed series on a scale by scale basis. A major finding of this paper is that the linear and nonlinear causal relationships between the real oil price and the real effective U.S. Dollar exchange rate vary over frequency bands as it depends on the time scales. Indeed, there is a strong bidirectional causal relationship between the real oil price and the real dollar exchange rate for large time horizons, i.e. corresponding to fundamentalist traders, especially fund managers and institutional investors. But, for the first frequency band which corresponds to a class of traders whom investment horizon is about 3-months and whom trading is principally speculative (noise traders), the causality runs only from the real oil prices to real effective U.S dollar exchange rate.     

Exchange rate volatility and exports from East Asian countries to Japan and the USA

The purpose of this article is to investigate the impact of exchange rate volatility on exports in four East Asian countries (Hong Kong, South Korea, Singapore, and Thailand). Specifically, this article aims at determining whether the bilateral real exchange rate volatility between an East Asian country and its trading partner negatively affects the exports of the East Asian country. Considering the dominant roles of the USA and Japan as trading partners of those East Asian countries, this article focuses on the quarterly export volumes of East Asian countries to the US and Japan for the period from 1981 to 2004. Except for the case of Hong Kong's exports to Japan, cointegration tests and estimations of error correction models indicate exchange rate volatility has negative impacts on exports either in the short-run or in the long-run, or both. On the other hand, the real GDP of importing countries and depreciation of real bilateral exchange rates turn out, in general, to have positive effects. Of special interest is the finding that the impact of the exchange rate volatility does not show any stylized differences depending on whether the importing country is Japan or the USA, even though dollar invoicing dominates in East Asia.     

The persistence in real exchange rate: Evidence from East Asian countries

In this article, we examine the degree of persistence in monthly real exchange rate of six East Asian countries in relation to their two major trading partners, the United States and Japan, to study the validity of PPP for the 1976:01–2009:03 period. To investigate the persistency in real exchange rate series, we use sum of the autoregressive (AR) coefficients and the confidence interval for it using grid-bootstrap procedure recently developed by Hansen (1999). We have two findings: first, we find evidence for high persistency in real exchange rate in terms of the Japanese yen for five countries and for four countries in terms of the US dollar the for the full and pre-crisis sample periods. Second, for the post-crisis period, the presence of low persistency in real exchange rate supports PPP for three countries in terms of the Japanese yen and five countries in terms of the US dollar. These findings indicate that real exchange rate series of five East Asian countries are mean-revert based on their exchange rate policies and East Asian countries can form a currency union.     

The J-curve: evidence from commodity trade between US 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.     

基于中国主要贸易伙伴双边数据的贸易收支弹性研究

有别于传统的总量分析,利用双边贸易收支模型考量人民币汇率波动与双边贸易收支的关系,能更深刻地揭示汇率波动与我国贸易收支的关系.研究发现,无论是在短期还是在长期,对不同国家而言,不仅双边汇率对双边贸易收支的弹性系数大小不一样,而且双边汇率的波动对贸易收支的影响方向也并不一致,这也说明了采用双边汇率和双边贸易收支样本比总量样本更具有针对性和实践意义.
