The Impact of Korea's Exchange Rate Volatility on Korean Trade

This study uses a GARCH-in-mean model to analyse the impact of Korea's nominal exchange rate volatility on exports and export prices over the current flexible-rate period. The volatility of Korea's won increases the exchange risk of exporters and leads to changes in export volume and price. This paper provides some evidence that nominal exchange rate volatility has had a statistically significant impact on real exports over the current floating-rate period. We show that persistence-in-variance of exchange rates affects the market for exports in Korea. An important result is that the effect of exchange rate volatility on trade variables is shown to be significant. We find that the GARCH conditional variance has a statistically significant impact on the reduced form equations. The magnitude of the effect is generally stronger for export quantities than prices. This result is contradicts that of Kroner and Lastrapes's analysis. This is explained by the fact that Korean exporters choose the strategy of pricing to maintain market share instead of adjusting export prices to reflect exchange rate changes, even when this cuts profit margins.

Exchange rate volatility,international trade and labour demand

The purpose of this study is to assess under what conditions exchange rate volatility generates a positive effect on an exporting firm’s labour demand. As the exchange rate volatility increases, so does the value of the export option, provided that firms are flexible with respect to international trade. Higher volatility increases the potential gains from trade and can increase the demand for labour. The firm’s trade flexibility can be interpreted as a real hedging strategy when financial markets are incomplete. In many newly industrializing countries and emerging economies financial markets are imperfect or risk sharing markets are just starting to develop at a rather slow pace.     

Exchange rate volatility and ASEAN-4’s trade flows: is there a third country effect?

This paper investigates the impact of exchange rate volatility on the trade flows among ASEAN-4 countries (Indonesia, Malaysia, Singapore and Thailand) as well as to their five main trading partners. External volatility is included in the models to study the ‘third country’ effect on the trade flows. We employ annual import and export data over the period of 1980–2012. The results from the bounds testing approach to cointegration and error-correction model reveal that the real exchange rate volatility does play a significant role in 15 export and four import models in short-run and long-run. Moreover, in both import and export models, the effects of exchange rate volatility on trade flows are negative rather than positive. Finally, the effects of volatility from the ASEAN-4’s currency/yuan rate dominate the third country effect on the ASEAN-4’s trade.     

Financial market integration,exchange rate policy,and the dynamics of business and employment in Korea

We study the consequences of different degrees of international financial market integration and exchange rate policies in a calibrated, medium-scale model of the Korean economy. The model features endogenous producer entry into domestic and export markets and search-and-matching frictions in labor markets. This allows us to highlight the consequences of financial integration and the exchange rate regime for the dynamics of business creation and unemployment. We show that, under flexible exchange rates, access to international financial markets increases the volatility of both business creation and the number of exporting plants, but the effects on employment volatility are more modest. Pegging the exchange rate can have unfavorable consequences for the effects of terms of trade appreciation, but more financial integration is beneficial under a peg if the economy is subject to both productivity and terms of trade shocks. The combination of a floating exchange rate and internationally complete markets would be the best scenario for Korea among those we focus on.     

人民币实际汇率波动对中欧进出口贸易影响的实证研究

本文通过建立GARCH模型量度了人民币对欧元实际汇率的波动性,并运用协整检验模型、误差修正模型、脉冲响应函数和方差分解技术就人民币实际汇率变动对中国与欧元区之间进出口贸易的影响进行分析。分析结果表明,中国对欧元区出口在长期内随汇率波动而增加,而进口却随汇率波动而减少;在短期内汇率波动推动中国进口,抑制中国出口。人民币升值在长期内给双边出口均造成伤害,但对中国出口伤害更大;在短期内人民币贬值将对中国进出口均有推动作用。本文分析还表明,在长期内,中国对欧元区出口收入效应远远大于欧元区对华出口收入效应;在短期内,中国实际收入变动对欧元区出口表现负向冲击,而欧元区实际收入变动对中国出口表现为正向冲击。中国汇率制度改革对中国出口欧元区产生推动作用,对欧元区出口产生抑制作用,且前者大于后者。实际汇率水平及其波动性变化对欧元区对华出口变动的解释力高于中国实际收入水平变化的解释力,而对于中国对欧元区出口的变动,欧元区实际收入水平变动的解释力高于实际汇率水平及其波动性变化的解释力。     

汇率变动的农业贸易效应模型述评

已有文献从微观和宏观视角构建了汇率变动的农业贸易效应模型,指出汇率水平变动、汇率波动性风险负面影响农业贸易流。尽管这些模型得出了一致的结论,但却根基于不同的假定之上,由此可将其归结为出口供给模型、进口需求模型、出口供给进口需求均衡模型、出口需求方程、引力模型五类。对于前三类模型,要得出汇率波动性风险负面影响农业贸易流的结论,必须依赖于厂商风险厌恶假设。未来研究需要基于发展中国家特点提出假设条件拓展已有模型,同时在模型中引入合适的变量,以突出农业贸易特征。     

Exchange Rate Volatility and Trade: An Empirical Investigation from Cross‐country Comparison

Abstract: This paper investigates empirically the impact of exchange rate volatility on the trade flows of six countries over the quarterly period of 1980–2005. The impact of a volatility term on trade is examined by using an Engle‐Granger residual‐based cointegrating technique. The major results show that increases in the volatility of the real exchange rate, approximating exchange‐rate uncertainty, exert a significant negative effect on trade for South Korea, Pakistan, Poland and South Africa and a positive effect for Turkey and Hungary in the long run.     

进口国汇率及其波动对福建省出口贸易的影响

本文利用月度数据,研究进口国名义汇率、名义汇率波动率、实际汇率、实际汇率波动率对福建省出口贸易的影响,通过协整检验来估计各变量间长期均衡关系。研究表明,福建省向美日韩、欧盟等国的出口与该国汇率及其波动无关,而福建省向香港、台湾、新加坡等地的出口则很大程度上受到其汇率水平变化的影响,但汇率波动率的影响却较小。同时,实证检验还发现,对于关注汇率变化的进口国而言,名义汇率和实际汇率水平的变化,对贸易的影响程度基本相同。     

The effect of exchange rate volatility on international trade in East Asia

In this paper, we empirically investigate the relationship between exchange rate volatility and international trade, focusing on East Asia. Our findings are summarized as follows: first, intra-East Asian trade is discouraged by exchange rate volatility more seriously than trade in other regions. Second, one important source of the discouragement is that intermediate goods trade in international production networks, which is quite sensitive to exchange rate volatility compared with other types of trade, occupies a significant fraction of East Asian trade. Third, the negative effect of the volatility is greater than that of tariffs and smaller than that of distance-related costs in East Asia.     

汇率的不确定性、投资区位选择与公司内贸易

本文通过建立投资国一受资国一国际市场的三国框架,分三种投资区位的国际生产模式,就汇率冲击对垂直型FDI的区位选择和公司内贸易的影响进行分析。研究表明：（1）当区位成本优势不能抵消汇率不确定性导致的损失时,跨国企业将会调整投资区位决策,考虑撤资回母国;（2）当汇率相对波动幅度处于某一范围时,跨国企业具有较强烈的倾向将投资从原东道国转移到其引资竞争国;（3）汇率不确定性对出口价格的传导效应,具有不完全性特点。出口价格的汇率波动风险弹性取决于国际市场的外部竞争度以及子公司组装成本占国际市场该产品价格的比重;（4）汇率波动风险对公司内贸易余额的传导程度具有不确定性。随着汇率风险程度的逐步加大,其对公司内贸易余额的影响作用渐强,逐步从弱弹性转化为较强弹性的传导。     

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 Volatility and Growth in Emerging Europe and East Asia

The paper investigates the impact of exchange rate volatility on growth in Emerging Europe and East Asia. Exchange rate stability has been argued to affect growth negatively as it deprives countries from the ability to react in a flexible way to asymmetric real shocks and increases the probability of speculative capital inflows and overheating. In contrast, exchange rate stability can be argued to affect growth in emerging market economies positively as transactions costs for international trade decline, uncertainty for international capital flows is less and macroeconomic stability is enhanced. Cross country panel estimations provide evidence for a negative impact of the exchange rate volatility on growth in both Emerging Europe and East Asia. Parts of this negative growth effect can be associated with exchange rate volatility caused by macroeconomic instability.     

The Declining Impact of Exchange Rate Volatility on Trade

The introduction of the euro in 1999 eliminated exchange rate volatility between the members of the eurozone. Despite the elimination of currency risks, trade flows within the eurozone hardly increased (Bun and Klaassen in Oxf Bull Econ Stat 69:473–496, 2007, Santos Silva and Tenreyro, 2009). Using a standard gravity model, we find that nominal exchange rate volatility has had a negative effect on trade before 1985 but that this effect disappeared in later years, coinciding with the introduction and rapid diffusion of over-the-counter currency swaps. The estimated coefficient for the euro dummy does not change when we include nominal exchange rate volatility as an additional regressor. This confirms our finding that the impact of exchange rate volatility on trade has been small in more recent years.     

Chinese exchange rate and price effects on G3 import prices

This paper explores the degree of price and exchange rate interdependence between China and the G3 (US, Japan and the Euro-zone) by undertaking a VAR based shock analysis. A GARCH framework is also employed to derive the conditional variances to uncover the extent of volatility transmission. We address two key issues. First as there have been concerns about low value-added cheap Chinese goods flooding G3 markets, we attempt to measure the impact of Chinese prices on G3 import prices. Second, we focus on the transmission of exchange rate shocks – a subject which we approach by examining shocks in China's bilateral exchange rate with each of these major trading partners (the US, Japan and the Euro Area). Our results indicate that reduced import prices from China are the channel through which aggregate domestic prices in the G3 remain depressed, while the impact of the RMB exchange rate with G3 currencies appears less powerful. This finding implies that the Chinese authorities’ RMB exchange rate policy is relatively unimportant and, in particular, that a revaluation of the RMB would not do much to reduce the US trade deficit. In terms of volatility spillover, the relatively flexible RMB exchange rate against the Euro results in RMB-EUR volatility having a stronger influence than the more tightly controlled RMB-USD rate on the volatility of Chinese export prices.     

国际贸易结算币种的选择——实证分析及对中国的启示

本文首先总结了国际贸易结算货币的宏观前提条件和进出口商在贸易实践中的经验法则。继而通过收集全球41个国家1992～2007年的样本数据,从出口国货币、进口国货币和媒介货币计价结算三个视角进行实证研究。分析结果表明,除了汇率制度、货币的可兑换性等制度变量外,汇率的波动性、进出口贸易的规模、方向和结构也是影响结算币种选择的关键因素。因而,人民币国际结算若要取得重大进展,不仅要逐步完成资本项目的开放,完善汇率形成机制,还要努力实现贸易出口多元化,并致力于产品结构的优化升级。     

What Makes Currencies Volatile? An Empirical Investigation

Real effective exchange rate volatility is examined for 90 countries using monthly data from January 1990 to June 2006. Volatility decreases with openness to international trade and per capita GDP, and increases with inflation, particularly under a horizontal peg or band, and with terms-of-trade volatility. The choice of exchange rate regime matters. After controlling for these effects, an independent float adds at least 45% to the standard deviation of the real effective exchange rate, relative to a conventional peg, but most other regimes make little difference. The results are robust to alternative volatility measures and to sample selection bias.     

Determinants of bilateral trade: evidence from ASEAN+3

In this research, we investigate the determinants of international trade, employing a dataset of bilateral trade and economics characteristics in the ASEAN+3 countries. We include a large number of independent variables that potentially drive international trade. We also use various standard gravity model variables to maintain consistency with the current literature. The results provide some important insights into the determinants of bilateral trade and offer policy implications regarding the promotion of international trade for governments worldwide. In particular, we find that output asymmetry between countries positively explains bilateral trade. Moreover, the findings suggest that making use of comparative advantage by differentiating the export product structure is important in promoting international trade. We do not find a consistent impact from bilateral exchange rate volatility on bilateral trade. This result points to the importance of providing opportunities for the hedging of currency uncertainty to avoid its adverse effects on trade. The results for other standard gravity model variables are consistent with the results of previous theoretical and empirical research.     

贸易模式与不完全汇率传递——基于扩展的古诺模型的解释

本文采用一个扩展的古诺模型分析证明了贸易模式与不完全汇率传递的关系。首先,本文从破解人民币升值背景下中国贸易规模和贸易顺差仍持续增长这一谜题出发,分析了中国贸易模式和出口结构特征,描述了中国在国际生产价值链上的角色,阐述了垂直型产业内模式和中间产品占比较大的贸易结构对人民币汇率传递水平的影响。其次,对Dornbusch采用的古诺模型进行拓展,引入贸易模式变量,构建了一个局部均衡的理论模型。模型分析表明,产业市场结构、本国供应商的市场地位和贸易模式是影响出口价格的汇率传递水平的重要因素。最后,根据模型分析结论,提出相应的政策建议。     

Effect of exchange rate risk on intra-EC trade

Summary The smooth development of the EMS towrds an exchange rate system with fixed exchange rates among its member countries recently came to an abrupt (temporary) end. This raises the question whether exchange rate volatility is damaging to international trade. So far, it has remained an open empirical question whether exchange rate variability has the presumed negative effects. This article shows that the exports of five countries participating in the ERM have substantially benefited from the diminische exchange rate risk in the period from 1979 up to and including 1990. Contrary to former empirical studies, which deal with figures for total trade or total trade or total manufactures, the analysis here has been conducted for exports broken down by type of product. The study suggests that a more disaggregated analysis, with respect to products or sectors, might be a fruitful way of identifying the effects of exchange rate volatility on international trade.
