Sources of time-varying trade balance and real exchange rate dynamics in East Asia

A sticky-price model with minimal assumptions for identification is used to motivate a time-varying model that allows for state dependent innovations to explore the trade balance dynamics of a group of East Asian economies. This paper shows that the correlation between the trade balance and the real exchange has historically been highly conditional on the type of macroeconomic shock. Permanent (transitory) shocks have historically produced a positive (negative) correlation between the trade balance and real exchange rate over the last 20 years. Second, since the Asian financial crisis the real exchange rate dynamics of the East Asian countries have been dominated by persistent component(s), while the dynamics of the trade balance have been more influenced by transitory factors.     

The dollar-euro exchange rate and macroeconomic fundamentals: a time-varying coefficient approach

This paper investigates the temporal stability of the relationship between the Deutschmark/US dollar exchange rate and macroeconomic fundamentals. We use monthly data from 1975:01 to 2007:12. Applying a novel time-varying coefficient estimation approach, we come up with some interesting properties of our empirical model. Firstly, there is no stable long-run equilibrium relationship among fundamentals and exchange rates, since the breakdown of Bretton Woods. Secondly, there are no recurring regimes, i.e. across different regimes, either the coefficient values for the same fundamentals differ or the significance differs. Thirdly, there is no regime into which no fundamentals enter. Fourthly, the deviations resulting from the stepwise cointegrating relationship act as a significant error-correction mechanism. In other words, we are able to show that fundamentals play an important role in determining the exchange rate, but their impact differs significantly across different subperiods.     

Renminbi exchange rate exposure: evidence from Chinese industries

This paper investigates sensitivity of stock returns of industry-sorted Chinese firms with respect to renminbi exchange rate movements. Strong evidence of significant exposure is documented for 7 out of 16 Chinese industries. Evidence is also found of the size asymmetry effects. In addition, we explore the characteristics of the exposure, and detect evidence of significant exposure among non-exporters in some of the industries. Special attention is given to examining the time-varying exposure under the impact of the new Chinese exchange rate regime in place since 2005, in which even stronger exchange rate exposure is reported. The conditional exposure estimated in this paper also reveals the close relation between stock returns and changes of the renminbi exchange rate.

A model of exchange rate determination in a dual exchange rate mechanism

Summary In this paper a theoretical model of exchange rate determination in the dual exchange rate mechanism is established. The role of interest arbitrageurs, speculators and hedgers in the official and the financial markets (both spot and forward) is analysed. For each of the categories of participants excess demand functions for foreign exchange are derived, which lead to the equilibrium condition for the various market segments. Also the main links between the different markets are discussed.This paper is based on chapter II of my Ph. D. dissertation submitted to the John Hopkins University. I am grateful to Professors Bela Balassa and Kirg Niehans for helpful comments. Also Zoran Hodjera (IMF) and Paul De Grauwe (KUL) provided stimulating criticism.     

欧元汇率分析

1998年5月,在布鲁塞尔举行的欧盟首脑会议确认比利时、德国、西班牙、法国、爱尔兰、意大利、卢森堡、荷兰、奥地利、葡萄牙和芬兰等11国为欧元创始国,并任命杜伊森贝赫为欧洲中央银行第一任行长.     

Fundamental equilibrium exchange rates and exchange rate dynamics

This paper examines whether there is a tendency for actual exchange rates to return to their fundamental equilibrium exchange rates (FEERs) when the latter are estimated based on popular exchange rate models. Co-integration tests and unit root tests are applied. There is little evidence that the exchange rates of Japan and Germany have a reversion to the purchasing-power-parity (PPP) rates or Williamson's FEERs or the underlying external and internal balance (UEI) FEERs.

2005年我国实行新的汇率制度,人民币汇率的波动和弹性增强,给我国外向型企业的稳健经营带来了冲击。本文在对人民币汇率的未来走势以及由此带来的汇率风险进行分析的基础上,探讨了我国外向型企业应对汇率风险应采取的防范措施。     

Asian foreign exchange risk exposure

We find that about 25 percent of Asian firms experienced economically significant exposure effects to the US dollar and 22.5 percent to the Japanese yen for the period January 1993 to January 2003. The overall extent of exposure is not sample dependent; a depreciating (appreciating) Asian currency against foreign currencies has a net negative (positive) impact on stock returns. The extent to which firms are exposed to exchange rate fluctuations varies with return horizons; short-term exposure seems to be relatively well hedged, where considerable evidence of long-term exposure is found. Firms with weak liquidity positions tend to have smaller exposures. J. Japanese Int. Economies 21 (1) (2007) 16–37.     

关于汇率制度的文献综述

目前我们正经历着汇率制度研究多年来最重要的发展时期。自上世纪90年代中期以后,特别是近几年来,国际学术界对汇率制度理论的研究,出现了一个新的高潮。本文分为两部分:第一部分为汇率制度选择的理论综述,总结了经济学家从不同的影响因素出发,对汇率制度的选择得出的不同结论;第二部分为人民币汇率制度选择的文献综述,讨论了人民币应该继续钉住美元还是采取更灵活的汇率制度,以及在中国资本账户开放和加入W TO后人民币汇率制度的变化。     

关于利率与汇率联系的分析

一、研究利率与汇率联系的重要性 维护国家经济金融安全，寻求内部经济和外部经济平衡是各国追求的目标，利率和汇率的变动在实行这一目标中起着至关重要的作用。利率政策是实现内部均衡的关键，汇率政策是外部平衡的关键，而利率政策和汇率政策的协调配合是内外经济平衡的前提。虽然，我国尚未实现资本帐户开放，资本流入（出）仍受限制，汇率变动对调节资本流动的作用并未充分显现，我国还未实现利率市场化，利率与汇率之间的互动性不强，     

The foreign exchange exposure of Chinese banks

Using the capital market approach and the equity price data of 14 listed Chinese banks, this empirical study finds that there is a positive relationship between bank size and foreign exchange exposure. This relationship may reflect the larger foreign exchange operations and trading positions of larger Chinese banks and their significant indirect foreign exchange exposure arising from impacts of the renminbi exchange rate movements on their customers. Empirical evidence also suggests that the average foreign exchange exposures of state-owned and joint-stock commercial banks in China are higher than those of banks in Hong Kong, notwithstanding their limited participation in international banking businesses compared with their Hong Kong counterparts. It is also found that negative foreign exchange exposure is prevalent for larger Chinese banks, suggesting that an appreciation of the renminbi tends to reduce their equity value. It is therefore likely that the banking sector's performance will be hampered. Together with the fact that decreases in equity values generally imply a higher default risk, the effects of different scenarios of renminbi appreciation on the default risk of Chinese banks should therefore be closely monitored.     

Productivity and the Euro-Dollar exchange rate

This article analyses the impact of productivity developments in the United States and the euro area on the euro-dollar exchange rate. The article presents a new measure of relative average labour, productivity (ALP) which does not suffer from the biases implicit in readily available relative ALP data. Importantly, the patterns of these series differ widely. Employing the Johansen cointegration framework, four models are estimated using four different productivity proxies. Our results indicate that the extent to which productivity can explain the euro depreciation varies with the productivity proxy used: readily available measures explain most, our new, preferred measure least. In all models, however, productivity can explain only a fraction of the actual euro depreciation experienced in 1999–2000. JEL no.

Rural-led exchange rate appreciation in China

The departure of a factor in excess supply in a non-traded rural sector leads to a Rural-led Exchange Rate Real Appreciation (RERA), in a dual economy setup. The RERA highlights for the first time a potential link between intra-national factor movements and real exchange rates. In China, where there is excess labor employed in the production of (largely) non-traded rural goods, we attribute around one third of the recent appreciation of the real exchange rate – defined as the relative price of nontradables – to a RERA effect.     

Restructuring East Asian exchange rate regimes

This paper investigated the degree of misalignment of the East Asian currencies against the U.S. dollar and against the Japanese yen under a de facto dollar-pegged exchange rate regime (January 1995 to May 1997). We found that overvaluation against the yen started in the Malaysian ringgit and the Philippine peso from January 1996 and the Thai baht from June 1996. Although the Indonesian rupiah and the Korean won against the yen were still undervalued in May 1997, degree of misalignment of both currencies narrowed from April 1995. Large withdrawal of Japanese claims after the financial crisis reduced Japanese bank lendings from $123.8 billion to $85.9 billion in end-June 1998. In 1998, Japanese Foreign Direct Investment (FDI) to East Asia fell as much as 44% from the previous year. In conclusion the paper stresses the importance of the stability in yen/dollar exchange rate to avoid large volatility in Japanese capital flow.     

Structural change through exchange rate policy

Zusammenfassung Strukturwandel durch Wechselkurspolitik. -Dieser Aufsatz untersucht, ob und wie die Wechselkurspolitik Produktivit?t und Qualit?t industrieller Produkte beeinflu?t. Anhand ?sterreichischer Daten wird gezeigt, da? Aufwertungen des Schillings die strukturelle Anpassung im ?sterreichischen Exportsektor begünstigt haben. In den siebziger Jahren haben reale Aufwertungen die Produktivit?t erh?ht und die Produktqualit?t verbessert, weil die Firmen ihre Wettbewerbsf?higkeit aufrechterhalten wollten. Es wird gezeigt, da? dies im Einklang mit dem Produktzyklusmodell und dem Modell des importinduzierten Wachstums steht, welche eine positive Beziehung zwischen dem Wechselkurs und der nicht durch den Preis bestimmten Wettbewerbsf?higkeit nahelegen.

Résumé Changement structurel par la politique de taux de change. -Cet article explore l'influence de la politique de taux de change sur la productivité industrielle et la qualité des produits. Il est démontré par des données autrichiennes que les révalorisations du schilling ont favorisé l'ajustement structurel dans le secteur exportatrice autrichien. Pendant les années soixante-dix les révalorisations réels ont mené à une productivité plus haute et amélioré la qualité des produits parce que les entreprises cherchaient à maintenir leur capacité concurrentielle. Suivant l'auteur cela se trouve en conformité avec le ?product-cycle? modèle et le ?import-led-growth? modèle suggérant une relation positive entre le taux de change et la capacité concurrentielle non-prix.

Resumen Ajuste estructural através de la política cambiaria. -Este trabajo explora el efecto de la política de cambios sobre la productividad industrial y la calidad de los productos. Utilizando datos austríacos se muestra que las revaluaciones del tipo de cambio favorecen el ajuste estructural en el sector exportador austríaco. En los a?os setenta, las revaluaciones del tipo de cambio contribuyeron a aumentar la productividad y a mejorar la calidad de los productos, dado que las empresas estaban preocupadas por mantener su margen competitivo. Esto concuerda con la teoría del ciclo del producto y con el modelo de crecimiento inducido hacia las importaciones, que sugiere la existencia de una relación positiva entre el tipo de cambio y la competitividad no basada en el precio.

     

Application of ANFIS to exchange rate forecasting

The need of exchange rate forecasting in order to preventing its disruptive movements has engrossed many policy-makers and economists for many years. The determinants of exchange rate have grown manifold making its behavior complex, nonlinear and volatile so that nonlinear models have better performance for its forecasting. In this study the accuracy of ANFIS as the nonlinear model and ARIMA as the linear models for forecasting 2, 4 and 8 days ahead of daily Iran Rial/∈ and Rial/US$ was compared. Using forecast evaluation criteria we found that nonlinear model outperforms linear model in all three horizons.     

Volatility behavior of exchange rate future contracts

The increasing globalization of economies and the concurrent increase in the risk of currency exposure has stimulated the development of new instruments to allow both investors and traders to hedge their currency risk. The expansion of these derivatives, however, has raised some concerns. This paper studies the determinants of the dynamics of exchange rate future contracts as a means to identify the sources of such concerns. By using a mean-exponential generalized autoregressive conditional heteroskedasticity (M-EGARCH) model for five different future contract lengths and six developed economies, it is found that an M-EGARCH(1,1) effectively describes the exchange rate futures' daily dynamic. Sign, size, and persistence effects on the volatility of future contracts are all significant, thus providing important information to both policy makers and market participants.     

Long-run consequences of finite exchange rate bubbles

This paper draws on the literature on exchange rate instability and on sunk-cost hysteresis to analyze the long-run effects of exchange rate bubbles. To address the issue, after discussing the implications of sunk-cost hysteresis for aggregate supply, we propose two versions of the Dornbusch (1976) model of exchange rate determination. We modify it so as to allow for endogenous adjustment in productive capacity, with the aggregate investment function being linear with respect to the exchange rate in one version and non-linear in the other. For both versions, we provide solutions for a Blanchard-type bubble developing on the foreign exchange market. We find that, if capacity adjusts non-linearly, such a bubble will affect the steady state of the economy.
