Asymmetric Effect of Currency Union for Developing Countries

The large effect of currency union on trade volume has been well documented by Rose (2000). However, the effect of currency union on trade balance has hardly been previously reported. In this study, the effect of currency union is found to differ substantially across imports and exports when a developing country trade with developed country that anchors the currency. To ensure that the asymmetric effect does not come from the specific nature of countries that have adopted a common currency or endogeneity of currency union, we test the same hypothesis using nominal exchange rate volatility and real exchange rate level.     

Volatility of industrial production growth and characteristics of optimal currency areas in EU-12 countries

This paper investigates how the introduction of the euro in the EU-12 countries influenced the short-term volatility of output, measured by the volatility of industrial production growth. It assesses whether more favorable criteria of optimum currency areas keep the volatility of industrial production growth constant. Finally, it investigates the impact of the global financial crisis on the volatility of industrial production growth and on the characteristics of the optimum currency areas of the EU-12 countries. This paper uses the Chow breakpoint test and the Quandt-Andrews test to check for structural breaks in the volatility obtained from ARMA (p,q) and AR(p)-EGARCH(1,1) models. The results suggest that after the introduction of the euro, the volatility of industrial production growth has not significantly changed in Austria, France, Luxembourg, the Netherlands and Spain. However, the volatility of industrial production growth did increase in Finland, Ireland, Italy, Luxembourg and Portugal after the adoption of the common currency. In Germany and Greece the volatility of industrial production increased after 2002 and 1997 respectively. This observation cannot be connected directly to the introduction of the euro. After the beginning of the financial crisis, the volatility of industrial production growth increased in all EU-12 countries except France and Greece. Criteria for optimum currency areas fail to explain why the volatility of some EU-12 countries remained unchanged after the introduction of the euro and after the start of the financial crisis. Those countries, where the volatility of industrial production has not changed significantly after the introduction of the euro, had a long history of fixed or pegged exchange rate regimes. This group of countries recovered faster after the financial crisis.     

Effect of exchange rate return on volatility spill-over across trading regions

This paper examines the effect of realized exchange rate returns on the volatility spill-over between the euro–US dollar and US dollar–yen currency pairs across the five trading regions: Asia, Asia–Europe overlap, Europe, Europe–America overlap and America. Modelling the interaction between returns and volatility in an autoregressive five-equation system, we find evidence that depreciation of the US dollar against the yen has a greater impact on the US dollar–yen volatility spill-over than appreciation in the subprime crisis period. Appreciation and depreciation of the US dollar against the euro does not appear to have an asymmetric effect on the euro–US dollar volatility spill-over. Our results support the notion that the yen may have been preferred to the euro as a ‘safe-haven’ currency relative to the US dollar during the subprime crisis period.     

Optimal currency shares in international reserves: The impact of the euro and the prospects for the dollar

Foreign exchange reserve accumulation has risen dramatically in recent years. The introduction of the euro, greater liquidity in other major currencies, and the rising current account deficits and external debt of the United States have increased the pressure on central banks to diversify away from the US dollar. A major portfolio shift would significantly affect exchange rates and the status of the dollar as the dominant international currency. We develop a dynamic mean-variance optimization framework with portfolio rebalancing costs to estimate optimal portfolio weights among the main international currencies. Making various assumptions on expected currency returns and the variance–covariance structure, we assess how the euro has changed this allocation. We then perform simulations for the optimal currency allocations of four large emerging market countries (Brazil, Russia, India and China), adding constraints that reflect a central bank's desire to hold a sizable portion of its portfolio in the currencies of its peg, its foreign debt and its international trade. Our main results are: (i) The optimizer can match the large share of the US dollar in reserves, when the dollar is the reference (risk-free) currency. (ii) The optimum portfolios show a much lower weight for the euro than is observed. This suggests that the euro may already enjoy an enhanced role as an international reserve currency (“punching above its weight”). (iii) Growth in issuance of euro-denominated securities, a rise in euro zone trade with key emerging markets, and increased use of the euro as a currency peg, would all work towards raising the optimal euro shares, with the last factor being quantitatively the most important.

Currency unions and trade: The special case of EMU

In this paper, the impact of the adoption of the euro on the commercial transactions of EMU countries is investigated. It seeks to disentangle the effects of eliminating exchange rate volatility — and those of other policy factors that promote integration — from the influence of the emergence of the European currency union. Since EMU is a relatively new phenomenon, a panel estimation of the gravity equation in a dynamic framework is used in order to capture effects like trade persistence. The main finding is that the adoption of the euro has had a positive but not an exorbitant impact on bilateral trade between European countries (ranging between 9 and 10 per cent). The impact is much lower than that shown in the recent literature on a larger and heterogeneous set of countries. One reason for this divergence seems to be that the euro was adopted after decades of integration policies had already worked through in Europe. JEL no. F4, F15, C230     

Labour costs dynamics in the Euro area: some empirical evidence

Little is known about how the introduction of a common currency and a single monetary policy has affected the labour cost dynamics in the Euro area. The literature has focused mainly on business cycle synchronisation. This paper analyses labour costs convergence in the Euro area since 1995, combining results from different data and two complementary approaches. First we present some relevant facts about wages and unit labour cost dynamics and, in a second phase, we investigate whether the physical introduction of the euro has changed the volatility and the synchronisation of labour costs cycles, in a context of globalisation. Overall, our results indicate that labour markets in the Euro area are very heterogeneous. However, some signs of labour cost convergence are beginning to emerge. After the circulation of the euro, it seems that a reduction in nominal unit labour costs differences and an increase on the degree of synchronisation has occurred, which has been strengthened in the economic and financial crisis period.     

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.     

Rose effect and the euro: is the magic gone?

This paper presents an updated meta-analysis of the effect of currency unions on trade, focusing on the euro area. Using meta-regression methods such as the funnel asymmetry test, evidence for strong publication bias is found. The estimated underlying effect for currency unions other than the eurozone reaches more than 60%. However, according to the meta-regression analysis, the euro’s trade promoting effect corrected for publication bias is insignificant. The Rose effect literature shows signs of the economics research cycle: reported t-statistic is a quadratic concave function of the publication year. Explanatory meta-regression (robust fixed effects and random effects), that can explain about 70% of the heterogeneity in the literature, suggests that results published by some authors might consistently differ from the mainstream output and that study outcomes are systematically dependent on study design (usage of panel data, short- or long-run nature, number of countries in the data set).     

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.

Monetary policy and EMU enlargement: Issues regarding ERM II and adoption of the euro in Estonia

The aim of the paper is to give an overview of the issues related to Estonia's entry into ERM II. For that purpose the article describes the official position of the Estonian authorities regarding entry into ERM II and the adoption of the euro, explains the rationale for early entry into ERM II, and presents the reasons for maintaining the currency board arrangement until full membership in EMU. Also, the challenges of the adoption of the euro are discussed. The article concludes that early entry into ERM II is appropriate as the perceived costs—short-term costs of fiscal consolidation and the cost of giving up independent monetary policy and flexible exchange rates as stabilization tools—are practically non-existent in Estonia. The paper argues that the high level of exchange rate stability and nominal convergence, relatively high flexibility of the economy, and integration with the euro area support the rationale for maintaining the currency board arrangement and adopting the euro early.     

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 the euro means for the dollar and the international Monetary system

This article begins by analyzing the hirtorical importance of the introduction of the euro, the convergence criteria for membership in the European Monetary Union, the merits and defects of the euro as an international rival to the dollar, and the characteristics that have made past international currencies great. It goes on to consider the institutional gap in the world system arising from the absence of an official world currency and the threat to stability that arises in transition periods when a new international reserve asset or currency is phased in. It is argued that the introduction of the euro will involve diversification from the dollar that will require multilateral attention to the dollar-euro exchange rate.Distinguished Address presented at the Forty-Fifth International Atlantic Economic Conference, Rome, Italy, March 14–21, 1998.     

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%。     

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.     

Is Asian Currency Unit Attractive to East Asian Economies？

Pegging the RMB exchange rate to the Asian currency unit (ACU) has not, at least in the short term, been proved a better solution than pegging to the US dollar or pegging to a G‐3 (US$, Japanese yen and euro) currency basket. Although the Asian currency unit can help Asian economies to keep the relative price of regional currencies stable, the cost of joining a formal regional monetary cooperation is the relinquishment of the autonomy of their domestic policies. Asian monetary cooperation needs to provide more potential benefits if it is to attract Asian economies. We argue that Asian monetary cooperation should be designed to solve the problem of regional trade imbalance, and regional exchange rate policy coordination should be adopted as the first step towards exchange rate cooperation.

The euro and its consequences: What makes a currency strong?

The creation of the Economic and Monetary Union (EMU) and the introduction of the euro was one of the great events in economic history after World War II. The basic attractiveness of the euro is its large and expanding transaction size and the independent central bank which pursues price stability as its primary goal. The basic strength of the dollar is the hysteresis effect based on economies of scale and network externalities. The conclusion in the paper is that at present the hysteresis effect dominates the sheer size effect and the dollar remains the key vehicle currency while the euro has established itself as the second most widely used currency in the world. The euro depreciated against the dollar in the first three years after its introduction. In the paper the euro weakness is explained by the positive growth differential in favor of the U.S. economy caused by the advance in IC-technology and a pick-up in total factor productivity. In the medium run, the outlook for the euro is favorable. The U.S. current account deficit is unsustainable and improvements require a substantial depreciation of the dollar.Distinguished Address presented at the Fifty-Fourth International Atlantic Economic Conference, Washington D.C., October 10–13, 2002.     

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.
