人民币汇率制度改革以及汇率波动性研究

自我国1978年改革开放以来,我国汇率制度的改革大体上经过了3个阶段:复汇率制度、单一有管理浮动汇率制度、参考"一篮子货币"有管理浮动汇率制度。本文着重讲述了这三个阶段汇率制度的改革情况,分析了人民币兑美元的汇率走势,并对汇率波动性进行实证研究,然后指出我国汇率制度当前存在的问题,以及针对这些问题提出改革的下一步路径。     

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.     

新汇率制度下我国外向型企业汇率风险的防范

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。     

Sources of time-varying exchange rate exposure

We report evidence of a time-varying link between returns on national stock market indexes and exchange rate returns (exchange rate exposure). We use this evidence to analyze the sources of changes over time in exchange rate exposure. Using monthly data for 14 industrialized countries for the period 1975–2006, we report evidence of a cointegration relation between exchange rate exposure and the industry composition of a country’s imports, and weaker evidence of a cointegration relation between exchange rate exposure and openness to trade.     

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，     

Stochastic behavior of nominal exchange rates

This article is concerned with the statistical modeling of the daily structure of the nominal exchange rates in the U.K., Germany, and Japan, as well as their returns in relation to the U.S. dollar by means of using fractionally integrated techniques. Using a version of the tests of Robinson [1994] that permits us to tests I(d) statistical models, the results show that the three time series are I(1), finding strong evidence against fractional integration and against mean reversion. Similarly for the return series, all them appear to be stationary I(0) with no evidence of fractional integration of any degree in any series.     

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.     

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.

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.

     

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.     

人民币汇率政策的选择

1997年东亚金融危机以来,人民币汇率问题一直是世人关注的焦点,特别随着中国加入WTO的临近,人民币贬值论的呼声愈来愈高。本文对几种典型的贬值论主张进行了富有针对性的分析,指出我国仍然应该实行稳定的汇率政策,并对完善人民币汇率制度提出了若干政策建议。     

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.     

利率市场化进程中针对汇率市场化改革的探讨

所谓利率市场化是指由市场自主决定利率。利率的市场化至少应该包括以下几个内容：①金融交易主体有利率决定权；②利率的数量结构、期限结构和风险结构应由市场自发选择；③同业拆借利率或短期国债利率将成为市场利率的基本指针，也是衡量市场利率水平涨跌的基本依据；④政府或中央银行享有依靠间接手段影响金融资产利率的权力。也就是说，货币市场严格遵守价格规律。     

我国外汇储备影响因素分析与汇率制度选择

本文通过误差修正模型分析了我国外汇储备长期和短期的影响因素,认为短期影响因素是进出口额与外商直接投资。根据模型结论,本文认为继续深化汇率体制改革,适度加快人民币升值和扩大波动区间,利用汇率自身与对进出口额的杠杆作用,直接和间接地将外汇储备控制在合理的范围内。     

本币名义汇率低于真实汇率是保持国际竞争力的有效手段

本文表达了如下想法:①名义汇率围绕真实汇率上下波动的调整,会促使一国国际收支恶化或者改善;②美元对人民币贬值并不一定能够满足马歇尔———勒纳条件和解决中美国际收支失衡问题,因为失衡问题主要是美国的国内因素以及限制对华技术出口与中国商品进口所引起的;③我国作为一个发展中国家,应该适度控制名义汇率,使其低于真实汇率,才能支持劳动力优势,保持国际收支顺差;④国际收支长期盈余,是我国经济增长和经济安全的保证。
