汇率波动、出口结构与贸易福利——基于要素流动与世界经济失衡的分析

研究世界经济失衡背景下,汇率波动对一国出口商品结构和贸易福利的影响具有重要的理论价值与现实意义。本文通过构建不完全竞争模型,研究了世界经济失衡条件下汇率波动对劳动力资源无限供给的国家(以中国为代表)的出口结构与出口福利的影响,并就汇率波动对不同要素密集度产业的出口量、企业利润、就业和出口贸易福利等进行了模拟分析。研究表明:具有一定资本要素密集度的劳动密集型产业的出口受汇率波动的影响最大;劳动密集型产业的出口受到的影响较大;资本密集型产业的出口所受的影响较小;汇率波动对各种产业出口幅度的不同影响将改变一国的出口商品结构。     

Trade diversion in a currency union

This paper examines the consequences of trade diversion within the framework of a three-country,n-goods, two-period model. Two of the countries form a currency union while their currency floats with regard to the one of the third country. Trade diversion here is a shift in import demand from the goods produced in the third country to those produced by the union partner. It will be shown that because of the direct demand effect and the real balance effect, trade diversion will clearly increase intertemporal welfare in both union countries.     

Monetary unions, external shocks and economic performance: A Latin American perspective

During the last few years there has been a renewed analysis in currency unions as a form of monetary arrangement. This new interest has been largely triggered by the Euro experience. Scholars and policy makers have asked about the optimal number of currencies in the world economy. They have analyzed whether different countries satisfy the traditional “optimal currency area” criteria. These include, among other: (a) the synchronization of the business cycle; (b) the degree of factor mobility; and (c) the extent of trade and financial integration. In this paper I analyze the desirability of a monetary union from a Latin American perspective. First, I review the existing literature on the subject. Second, I use a large data set to analyze the evidence on economic performance in currency union countries. I investigate these countries’ performance on four dimensions: (a) whether countries without a national currency have a lower occurrence of “sudden stop” episodes; (b) whether they have a lower occurrence of “current account reversal” episodes; (c) what is their ability to absorb international terms of trade shocks; and (d) what is their ability to absorb “sudden stops” and “current account reversals” shocks. I find that belonging to a currency union has not lower the probability of facing a sudden stop or a current account reversal. I also find that external shocks have been amplified in currency union countries. The degree of amplification is particularly large when compared to flexible exchange rate countries.     

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.     

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.     

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。     

实际汇率对欧元区内出口贸易影响的实证分析

汇率是调节一国进出口贸易的重要工具,在欧元区由于使用统一的货币,这使得成员国无法通过改变汇率来调节本国的进出口贸易,而成员国的通货膨胀率的不同造成了欧元区各国的实际汇率并不相同,实证分析发现,实际汇率与区内出口贸易存在着明显的负相关,实际汇率每增加1%,区内出口就会减少2.39%。

Exchange rates and the trade balance: the case of Singapore 1970 to 1996

The purpose of this paper is to examine the relationship between the real trade balance and the real exchange rate for bilateral trade in merchandise goods between Singapore and the USA on a quarterly basis over the period 1970 to 1996 using the partial reduced form model of Rose and Yellen (1989). We also hope to shed further light on what has become known as the ‘Singapore export puzzle’: the observation that, despite periods of rapid nominal and real appreciation of the Singapore dollar, export growth in aggregate has remained buoyant.Our findings suggest that the real exchange rate does not have a significant impact on the real bilateral trade balance for Singapore and the USA, thus confirming previous work which finds a weak relationship between changes in the exchange rate and changes in export and import prices and volumes for Singapore. We also found little evidence of a J-curve effect. Although positive coefficients linking real exports with lagged values of the real exchange rate might be indicative of ‘small country’ pricing by exporters in U.S. dollars, it is not clear that this is masking J-curve effects from an initial rise in import values as the home currency depreciates.     

Real effects of common currencies in East Asia

Since the 1997 Asian currency crisis, new interest has emerged in the formation of a common currency area in East Asia. This paper provides estimates of trade and welfare effects of East Asian currency unions, using a micro-founded gravity model. Counter-factual experiments to assess the effects of various hypothetical currency arrangements for East Asia suggest that an East Asian currency union will double bilateral trade in the region, but the resulting welfare effects will be moderate. However, if Japan, a major trade partner for East Asia, is included in the union, welfare effects increase substantially. The evidence thus suggests that certain regional currency arrangements in East Asia will stimulate regional trade rigorously and can generate economically significant welfare gains.     

High‐Frequency Contagion of Currency Crises in Asia*

Using daily data from the Asian currency crisis, the present paper examines high‐frequency contagion effects among six Asian countries. The ‘origin’ (of exchange rate depreciation, or decline in stock prices) and the ‘affected’ (currencies, or stock prices) in the daily spillover relationship were defined and identified. Indonesia is found to be the main origin country, affecting exchange rates of other countries. Contrary to conventional wisdom, evidence of high‐frequency crisis spillover from the Thai exchange rate to other currencies was weak at best. There exists a high‐frequency contagion in stock markets among East Asian countries. Contagion coefficients are positively correlated with trade indices, indicating that investors lower their financial assessment of a country that has trade linkage to a crisis origin country within days, if not hours, of a shock.     

The Choice of International Monetary Regimes in a Context of Repeated Games

A game theoretic and incentive approach is used to explain an international monetary regime. Decisions concerning a fixed exchange rate regime are difficult because they involve cooperation among participants, but decisions concerning defections from a fixed exchange rate regime are relatively easy because they are taken unilaterally. This may explain the difficulties for the completion of Economic and Monetary Union (EMU) in Europe well as the instability recently observed in the quasi-fixed exchange regimes of the Asian countries. EMU is now in full force. The perception of political benefits by national leaders has been the driving force of currency unification in Europe. The cost of a monetary union is the loss of monetary control by each participating nation. If countries cannot contain their desire to deviate from the common monetary expansion, then the currency could potentially be under speculative attack. After January 1, 1999, theoretically each EMU country can no longer deviate from the common norm; but the question remains how to implement this mode of conduct. Even the country in the center, Germany, may find a cost associated with the loss of its leadership role.     

Estimation of the East African Community's trade benefits from promoting intra‐regional trade

In the literature on economic integration, the optimum currency area (OCA) theory says that there should be a high degree of trade between potential members of a monetary union for them to benefit from the use of a single currency. This study uses an augmented gravity model of trade to estimate the East African Community's (EAC) trade effects, as this community decided to participate in a monetary union by 2024. The study uses the fixed effect filter (FEF) estimator, which follows a two‐step approach and outperforms the standard fixed effects (FE) estimator. The results indicate that EAC has the potential to increase trade among partner states by 122% more than expected from the normal trade levels. The study, therefore, supports the ongoing East African Monetary Union process. However, to improve the likelihood of creating a more sustainable monetary union, the study recommends these countries to primarily focus on the full implementation of the customs union and common market steps. The main contribution of this study is that it provides robust estimates of the EAC's effects on intra‐regional trade using more recent data and updated econometric techniques.     

The choice of an invoicing currency in international trade and the balance of trade impact of currency depreciation

Cross-country differences in the choice of an invoicing currency in international trade is one reason for cross-country differences in estimated exchange rate coefficients in short-run balance of trade equations. If exports are invoiced in domestic currency while imports are invoiced in a foreign currency, a depreciation will increase the domestic currency value of outstanding import contracts, and may cause the balance of trade to fall in the short run. Countries with different invoicing patterns will have different effects on the short-run trade balance following a depreciation. We explore a simple theory of invoicing currency choice, drawing inferences regarding the likely choices for 14 countries. This allows a classification of countries according to the expected short-run balance of trade effect of a currency depreciation. Empirical estimates support the hypothesized groupings based on suggested currency invoicing patterns.     

TRADE PATTERNS AND EXCHANGE RATE REGIMES: TESTING THE ASIAN CURRENCY BASKET USING AN INTERNATIONAL INPUT‐OUTPUT SYSTEM

This paper aims at analyzing exchange rates and trade patterns of Indonesia, Malaysia, the Philippines, Thailand, China, Korea, Singapore, and Taiwan in relation to Japan and the United States, with reference to the Asian currency crises in 1997. In order to analyze these issues, we constructed an international input‐output model linked with macroeconometric models of the ten countries/regions. Analyses on the Asian exchange rates with a currency basket peg framework show that the Asian exchange rate policy was the de‐facto dollar peg policy. As for trade patterns in relation to the yen‐dollar rate; when a country/region's industrial structure is similar to that of Japan's and the yen is weak, the appropriate change of the yen's weight proves to hold its competitiveness. By contrast, the weak yen shows a decrease of its imports, regarding complementary structure. In either case, however, effects are limited.     

Regional currency arrangements in North America

Choosing an exchange-rate regime is largely a matter of choosing the variables that will bear the brunt of adjustment to shocks and disturbances. Floating rates, supported by inflation-targeting regimes of varying degrees of transparency, have dominated currency arrangements in North America, especially after the peso crisis of 1994. Although the member countries have pursued their policy goals without formal coordination, their objectives have been very similar. Meanwhile, de facto integration of the three economies has continued, especially in the realm of cross-border production sharing. The result has been reduction of asymmetries and convergence of business cycles, as well as changes in balance of payments behavior and in the sensitivity of trade to the exchange rate. This paper explores the implications for monetary union.

货币互换协议、金融市场与中国对外直接投资

基于2003-2018年169个国家的面板数据,文章利用多期双重差分方法探讨了货币互换协议对我国对外直接投资规模与密集度的影响,并通过PSM-DID方法和证伪检验对模型的稳健性进行验证。在此基础上,运用中介效应和调节效应检验方法对货币互换政策的金融市场作用机制进行分析。研究发现,货币互换协议对我国OFDI规模与密集度均有显著积极影响;预期汇率风险是货币互换协议促进我国OFDI的重要影响机制,中介传导而非调节效应是主要影响渠道,而利率市场的影响机制尚未发挥作用。在经济全球化和复杂的国际形势下,这一研究对我国进一步推动国家间金融领域深化合作和推进人民币国际化以畅通国内国际双循环具有重要参考价值。     

Short-run and long-run effects of exchange rate change on trade balance: Evidence from China and its trading partners

As one of largest exporting countries in the world, China has experienced a large amount of trade surpluses for the past decade. However, a growing criticism has been focused on the manipulation of Chinese Yuan (RMB) exchange rate by the Chinese government. While China implemented the exchange rate reform policy in July 2005, the question, whether its currency is undervalued remains as a debatable issue. Different from previous studies by focusing on individual trading partners, this paper tests the short-run J-Curve hypothesis and long-run trade balance effect of real exchange rate between China and its eighteen major trading partners using a panel dataset over the 2005–2009 period. We adopt the methodologies of panel cointegration test, fully modified OLS for heterogeneous cointegrated panel (panel FMOLS) and panel error correction model (panel ECM) to investigate the above examination. Our empirical results lend support to the inverted J-curve hypothesis between China and its trading partners. However, we find that a real appreciation of RMB has a decreasing long-run effect on China's trade balance in only three of the eighteen trading partners, while it has an increasing long-run effect in five of the eighteen trading partners. These mixed findings, therefore, lead to the empirical evidence that the real appreciation of RMB has no overall long-run impact on China's trade balance.
