Exchange Rate Volatility and International Trade Flows in sub-Saharan Africa: Empirical Evidence

In this article, the authors examine the relationship between the volatility in exchange rates and the volume of international trade in sub-Saharan African countries. Using the gravity equation and annual data for the period 1998–2007, they find a statistically significant and negative correlation between the volatility in exchange rates and the volume of trade. The estimated elasticities show that the responsiveness of the flow of international trade to changes in exchange rate volatility is very small. This suggests that eliminating the volatility in the exchange rates will result in only small increments in the volume of trade. Accordingly, pursuing a policy of exchange rate stability would not be sufficient to significantly increase the volume of bilateral trade in the sub-Saharan African region.     

Volatility in Exchange Rate Components and the Volume of International Trade

By decomposing the changes in the real exchange rate series into fundamental and transitory components (market microstructure and stochastic element) and modeling the volatility in each via a GARCH process, this paper examines how volatility in exchange rate affects the volume of aggregate and disaggregate US trade with Canada, Germany, and Hong Kong during the 1989–2002 period. The results indicate significantly different impacts of volatility due to the fundamental and transitory components of the exchange rate series on US bilateral trade. While the findings suggest heterogeneous responses of traders to volatilities arising from different components of the real exchange rate, the impact of the volatility due to the fundamental component is also found to vary across commodities, implying disparities in the inter- and intra-trading arrangements made by traders of different goods in counteracting foreign exchange risk arising from changes in the economic fundamentals.     

Exchange Rate,Exchange Rate Volatility and Foreign Direct Investment

In the light of the importance of foreign direct investment (FDI) for the promotion of economic development, this paper examines the impact of the changes in the real exchange rate and its volatility on FDI. Examining Japan's FDI by industries, we found that the depreciation of the currency of the host country attracted FDI, while the high volatility of the exchange rate discouraged FDI. Our results suggest the need to avoid over‐valuation of the exchange rate and to maintain stable but flexible exchange rate in order to attract FDI.     

Real Exchange Rate Volatility on the Short- and Long-Run Trade Dynamics in Colombia

The short- and long-run implications of real exchange rate volatility on Colombian bilateral trade commodities and non-commodities with its major trade partners are analyzed from the perspectives of the Marshall-Lerner condition, a cointegration relation with other aggregate variables, and the J-curve hypothesis. Long-run equilibrium on the Colombian bilateral balance of trade with a country is more common when the trade volume is denominated in terms of one of the world's main currencies—as is the case of commodity trade and trade with a country whose national currency is one of these currencies. No evidence of the J-curve was found in any of the analyzed Colombian bilateral balances of trade. Opposite to the predictions of the J-curve hypothesis, more common are the scenarios of short-run improvements in the bilateral trade balances following a devaluation than are those with instantaneous declines. Improvements in the terms of trade are found to have a long-run deteriorating impact on the Colombian balance of trade, especially in the case of non-commodity trade. Policy makers should consider that continuous improvements in the Colombian terms of trade, as the ones recently observed, will ultimately be a detriment to the country's current balance of trade surplus.     

Third-Country Exchange Rate Volatility and Pakistan-U.S. Trade at Commodity Level

We add to the literature on the “Third-Country” effect by assessing the impact of rupee-dollar volatility on 116 U.S. industries that export to Pakistan and 53 U.S. industries that import from Pakistan. As two measures of “Third-Country” effects, we include volatility measures of rupee-yuan and dollar-yuan rates due to the increased role of China in the global economy. We find evidence of “Third-Country” effects in more than half of the industries. Among affected industries are many of the large U.S. exporting industries, but not large U.S. importing industries.     

The Effect of Real Exchange Rate Volatility on the Trade of Educational Services

This article finds that high levels of real exchange rate volatility between two trading partners significantly decrease the amount of educational services traded. Many academic institutions are actively looking to expand exports of educational services as a means of increasing revenues. Internal policies that reduce real exchange rate uncertainty may help encourage trade of educational services between countries where volatility is high. The discovery that real exchange rate volatility serves as a significant barrier to attracting educational export opportunities to certain countries underscores an obstacle that should and/or could be addressed as academic institutions strive to expand their international enrollments.     

Foreign Exchange Intervention and Exchange Rate Volatility in Zambia

The study analyzes the impact of central bank intervention on the volatility of the exchange rate in Zambia during the period of 1996–2013 Bank of Zambia (BoZ). (1996–2013). Annual Reports . Lusaka , Zambia : Author. [Google Scholar]. The empirical findings reveal a statistically weak negative impact of intervention on exchange rate volatility, suggesting that other policy instruments are required to augment foreign exchange interventions in dampening volatility in the exchange rate.     

Exchange Rate Volatility and Exports: New Empirical Evidence from the Emerging East Asian Economies

This paper examines the impact of bilateral real exchange rate volatility on real exports of five emerging East Asian countries among themselves as well as to 13 industrialised countries. We recognise the specificity of the exports between the emerging East Asian and industrialised countries and employ a generalised gravity model. In the empirical analysis we use a panel comprising 25 years of quarterly data and perform unit‐root and cointegration tests to verify the long‐run relationship among the variables. The results provide strong evidence that exchange rate volatility has a negative impact on the exports of emerging East Asian countries. In addition, the results suggest that the pattern of bilateral exports is influenced by third‐country variables. An increase in the price competitiveness of other emerging East Asian countries has a negative impact on a country’s exports to a destination market, but the magnitude of the impact is relatively small. These results are robust across different estimation techniques and do not depend on the variable chosen to proxy exchange rate uncertainty. The results of the GMM‐IV estimation also confirm the negative impact of exchange rate volatility on exports and suggest that this negative relationship is not driven by simultaneous causality bias.     

噪声交易、人民币汇率波动与汇率制度选择

本文构建了一个包含宏观经济基本面和外汇市场微观结构的理论模型,将进入外汇市场的噪声交易者数量内生化,合理解释了人民币汇率波动的形成机制。理论分析表明,汇率波动既与宏观经济基本面波动正相关,也与进入外汇市场的噪声交易者数量正相关。在给定宏观经济基本面波动的情况下,人民币汇率波动取决于噪声交易者对人民币风险溢价的预期。当噪声交易者对人民币风险溢价的预期较高时,实行有管理的浮动汇率制度能够有效抑制噪声交易者进入外汇市场,有助于降低人民币汇率波动并提升货币政策效果。基于理论分析结论,本文采用1996年1月至2015年6月的月度数据对中国的无抛补利率平价进行实证检验,间接测度了人民币外汇市场中噪声交易者数量的变化。实证结果显示,人民币外汇市场中噪声交易者的数量较多,且随着2012年4月后人民币汇率浮动区间的扩大,噪声交易者的数量明显增加。     

Intraday Volatility in Interest‐Rate and Foreign‐Exchange Markets: ARCH,Announcement, and Seasonality Effects

We explore the determinants of intraday volatility in interest‐rate and foreign‐exchange markets, focusing on the importance and interaction of three types of information in predicting intraday volatility: (a) knowledge of recent past volatilities (i.e., ARCH or Autoregressive Conditional Heteroskedasticity effects); (b) prior knowledge of when major scheduled macroeconomic announcements, such as the employment report or Producer Price Index, will be released; and (c) knowledge of seasonality patterns. We find that all three information sets have significant incremental predictive power, but macroeconomic announcements are the most important determinants of periods of very high intraday volatility (particularly in the interest‐rate markets). We show that because the three information sets are not independent, it is necessary to simultaneously consider all three to accurately measure intraday volatility patterns. For instance, we find that most of the previously documented time‐of‐day and day‐of‐the‐week volatility patterns in these markets are due to the tendency for macroeconomic announcements to occur on particular days and at particular times. Indeed, the familiar U‐shape completely disappears in the foreign‐exchange market. We also find that estimates of ARCH effects are considerably altered when we account for announcement effects and return periodicity; specifically, estimates of volatility persistence are sharply reduced. Separately, our results show that high volatility persists longer after shocks due to unscheduled announcements than after equivalent shocks due to scheduled announcements, indicating that market participants digest information much more quickly if they are prepared to receive it. However, contrary to results from equity markets, we find no evidence of a meaningful difference in volatility persistence after positive or negative price shocks. © 2001 John Wiley & Sons, Inc.

A Synthesis of the Effects of Exchange Rate Volatility on International Trade: A Meta-Regression Analysis

ABSTRACT

This article surveys literature that investigates the effects of exchange rate volatility on international trade. We perform meta-regression analysis on 41 studies with 807 estimates. We show that the empirical works exhibit substantial publication selection and show a significant genuine exchange rate volatility effect on trade flows after correction of publication bias. In addition, the literature reveals a pronounced heterogeneity with respect to model specifications, samples, time horizons, and countries’ characteristics. These findings are supported by separate assessment of primary studies with, respectively, total exports and sectoral exports as the dependent variable.     

Mexican Peso Futures and Exchange Rate Volatility

Abstract

The reintroduction of Mexican peso futures contracts in April 1995 resulted from a refocus of governmental policy to the use of market-based mechanisms to stabilize the exchange rate. Interest in the Mexican peso future contracts has been high as investors look to manage their exposure from transactions and investments denominated in pesos. This study utilizes a VAR framework to analyze the relationship between the volatility in the Mexican peso spot market and futures contracts trading activity. Shocks to the exchange rate volatility lead to increased hedg-ing-type activity. Furthermore, an increase in futures contracts trading activity (reflecting additional speculation-type activity) results in a short-run increase in volatility. A Granger Causality test also indicates a statistically significant link between spot price volatility and futures trading activity in the Mexican peso exchange market.

RESUMEN

La reintroducción de los contratos futuros del peso mexicano en abril de 1995, resultó del nuevo enfoque de la política gubernamental de usar los mecanismos de mercado para estabilizar la tasa cambiaria. Ha habido mucho interés en los contratos futuros del peso mexicano, ya que los inversores buscan administrar su exposición a las transacciones e inversiones denominadas en pesos. Este estudio utiliza el marco del VAR para analizar la relación existente entre la volatilidad del peso mexicano en el mercado spot y la actividad de negociación de los contratos futuros. Los choques sufridos por la volatilidad de la tasa cambiaria resultan en un aumento de las actividades del tipo hedging. Además, un aumento en la actividad de negociación de los contratos futuros (que refleja otras actividades de naturaleza especulativa) provoca, a corto plazo, un aumento en la volatilidad. Una prueba Granger Causality también indica un vínculo estadísticamente significativo entre la volatilidad del precio spot y la actividad de negociación del mercado futuro en el mercado cambiario del peso mexicano.

RESUMO

A reintrodução dos contratos futuros em peso mexicano, em abril de 1995, foi o resultado de uma revisão da política governamental, em relação ao uso dos mecanismos baseados no mercado para estabilizar a taxa de câmbio. Os juros dos contratos futuros, em peso mexicano, foram altos, devido ao cuidado dos investidores em administrar o risco das transaç[otilde]es e dos investimentos efetuados em pesos. Este estudo utiliza a estrutura VAR, para analisar o relacionamento entre a volatilidade do mercado local, em peso mexicano, e a atividade comercial de contratos futuros. Choques aplicados à volatilidade da taxa de câmbio contribuíram para o aumento das atividades típicas de hedging. Além disso, um crescimento da atividade comercial de contratos futuros (refletindo uma atividade basicamente especulativa) ocasiona um rápido aumento na volatilidade. O teste Granger Causality indica, também, um vínculo estatístico significativo entre a volatilidade do preço local e a atividade comercial de futuros no mercado cambial do peso mexicano.     

On the Causes and Effects of Exchange Rate Volatility on Economic Growth: Evidence from Ghana

What drives exchange rate volatility, and what are the effects of fluctuations in the exchange rate on economic growth in Ghana? These questions are the subject matter of this study. The results showed that while shocks to the exchange rate are mean reverting, misalignments tend to correct very sluggishly, with painful consequences in the short run as economic agents recalibrate their consumption and investment choices. About three quarters of shocks to the real exchange rate are self-driven, and the remaining one quarter or so is attributed to factors such as government expenditure and money supply growth, terms of trade and output shocks. Excessive volatility is found to be detrimental to economic growth; however, this is only up to a point as growth-enhancing effect can also emanate from innovation, and more efficient resource allocation.     

Real Exchange Rate Changes and the Trade Balance: The Evidence from Pakistan

This study uses quarterly data from July 1980 to June 2006 to explore the relationship between changes in real exchange rate and the trade balance of Pakistan. Applying the Auto Regressive Distributed Lag (ARDL) approach to cointegration, we examine the existence of a possible long-run relationship. We find the following: (1) a long-run relationship between the series exists, and (2) the coefficient of elasticity is negative and statistically significant, which does not support for the J-relation.

Given this, the policymakers should take a conservative approach in using currency devaluation to cure the fundamental disequilibrium in the balance of payments. It is likely that such policy may not produce the desired outcome—i.e., the trade balance may not improve.     

汇率风险与企业出口

为了让人民币成为国际上的重要储备货币和投资贸易上的重要结算货币,增加人民币汇率机制的灵活性并控制由此而增加的汇率风险是人民币国际化中回避不了的问题。很多政策制定者和学者担忧:这是否会损害中国的对外贸易利益?本文在Melitz模型的框架下,在理论上分析了汇率风险对企业出口贸易的影响机理;在实证上使用中国2000—2008年的企业出口贸易和工业统计数据①,在不同的稳健情形下检验的结果表明:汇率风险对出口贸易有着相互冲突的作用力,双边汇率风险抑制了企业的出口行为,与除了出口目的地之外的其他目的地之间的多边汇率波动风险促进了企业的出口贸易;出口企业出口的产品种类和出口目的地越多,企业就会在不同的目的地之间优化分配出口资源,吸收双边汇率风险的负面冲击效应,从总体上推动贸易的发展。该论证为央行进一步放松人民币汇率浮动幅度的改革提供了理论上的支持。     

东亚汇率变动能否为我国出口贸易带来竞争优势

本文通过对中国出口贸易增长与汇率波动的实证分析确定两者之间的数量关系,探讨汇率变化能否为中国出口贸易带来竞争优势。本文用因子分析法确定出主成分,再进行回归建模,并考察汇率指数项的贡献率,认为汇率波动对中国贸易出口的影响有限,中国没有因此带来出口贸易竞争优势,那种认为依靠汇率贬值来获得出口竞争优势的看法与事实不符。中国外贸出口的推动力和竞争优势主要来自国内经济体制改革以及外向型产业投资的迅速增长。     

贸易模式、汇率传递与人民币汇率安排

结合中国现行贸易模式的特点,文章从社会福利最大化目标入手,采用了新政治经济学中关于汇率制度战略选择的研究方法,对进一步扩大人民币汇率弹性和汇率升值的影响进行了分析.研究发现,加工贸易和一般贸易对汇率变动的反应弹性差异很大,不同国际贸易模式下的汇率传递系数是不同的.因此如果我国现行对外贸易依然以加工贸易为主,扩大汇率波动幅度在理论上并不会对我国社会福利产生严重影响.研究结果进一步支持加大汇率弹性更有利于丰富货币政策当局的工具选择范围,有助于国内货币政策独立性的保持,也有助于推进出口产业的结构调整和升级.是当前人民币汇率制度改革方向的合理选择.     

Exchange Rate Pass‐through and Currency Invoicing: Implications for Monetary Integration in East Asia

Exporter's price‐setting behaviour and currency invoicing play a key role in the literature on the new open‐economy macroeconomics. This paper estimates exchange rate pass‐through coefficients for the exports of four ASEAN countries: Indonesia, Malaysia, the Philippines and Thailand. In addition, previous estimates of pass‐through as well as invoicing behaviour in East Asia are discussed in the context of regional integration. The new pass‐through coefficients are estimated under two alternate specifications for up to 34 goods for each of the four ASEAN countries destined for up to 13 major markets. The results suggest: (a) little pass‐through is occurring in Southeast Asia and (b) this lack of pass‐through is more likely attributable to the fact that they are small countries in a relatively integrated market, rather than evidence of pricing to market. The implications for regional monetary integration of this apparently low degree of pass‐through are detailed.
