How frequent a BEER? Assessing the impact of data frequency on real exchange rate misalignment estimation

This article explores the robustness of Behavioural Equilibrium Exchange Rate models, employed to estimate real effective exchange rate misalignments, to the frequency of the underlying data. It compares misalignments stemming from an annual model, estimated since 1980, and a comparable quarterly model, estimated since 1999. The two sets of estimates are similar. Moreover, the in-sample power of quarterly REER misalignments in explaining subsequent REER developments is higher than that of the annual estimates. This article therefore suggests that the “optimal” frequency of a BEER model depends on whether its resulting estimates are employed for research purposes or for policy-making activities.     

The Effect of Changes in Real Exchange Rates on Employment: Evidence from Manufacturing Industries in China, 1980–2002

This paper analyzes the effect of changes in real exchange rate on manufacturing employment. Our theoretical model predicts the positive effect of depreciation of real exchange rate on employment through a firm’s expectation on changes in real exchange rate and the interaction between real exchange rate and a firm’s import and domestic input. Using China’s manufacturing data during the 1980–2003 period, we find that depreciation of real exchange rate promotes employment growth in manufacturing industries, while change in real exchange rate is not a significant factor in promoting wage growth. We also find that an increase in export share offsets partially the effects of real exchange rate on employment and real wages. Translated from Journal of World Economy, 2005, (4): (in Chinese)     

人民币汇率与外商直接投资关系研究——基于上海市的数据

运用Johansen协整检验、Granger因果检验、脉冲响应分析等实证方法研究上海市外商直接投资与人民币实际有效汇率及其波动之间的相关性,研究表明:上海市外商直接投资(FDI)与实际有效汇率(REER)、地区国内生产总值(GDP)和对外依存度(OPEN)显著正相关,与汇率波动(VOL)和平均工资(WAGE)显著负相关;短期内人民币实际有效汇率及其波动对上海市外商直接投资存在影响,且汇率的波动比其实际值的大小更能影响外商直接投资;实际有效汇率及其波动的冲击在零期对外商直接投资均没有影响,响应值在第四期达到最大,实际有效汇率对于外商直接投资的影响主要体现在投资时机的选择上。     

汇率失调、汇率中性假定和策略汇率

在资本不完全流动的情形下,汇率不仅是体现一国内部经济均衡和外部经济均衡的政策目标,也是一国政府实现其他政治、经济目标的重要政策工具。本文通过考察政府如何以汇率失调为代价,实现政治、经济等战略目标,并以此为基础提出策略汇率的概念,以完善对汇率失调的理论描述和加深对汇率失调内在机制的理解。本文还建立了汇率博弈的政治经济学模型,运用博弈论阐明策略汇率是一个Nash均衡结果。     

1997～2013年人民币均衡汇率失调程度的实证研究

利用行为均衡汇率理论模型对人民币汇率水平进行研究,建立了基于非抵补利率平价理论的行为均衡汇率模型,实证分析了1997～2013年人民币汇率的均衡汇率水平和失调程度;建立误差修正模型分析各变量对于人民币汇率水平的短期影响和人民币汇率系统自身的误差。分析表明：1997年1季度～2013年4季度,人民币实际汇率水平在均衡汇率水平附近波动的幅度不超过±2％。2010年至今,人民币汇率失调程度一直低于±1％,基本达到均衡水平。基于研究结论提出政策建议：一是合理利用政府支出的消费方向调节汇率水平;二是进一步规范与完善资本市场;三是逐步提升汇率的自我修正机制;四是加快推进中国经济转型。     

人民币均衡实际汇率的估计与实际汇率错位的测算

基于均衡实际汇率理论 ,本文应用多种经济计量方法实证分析了自 2 0世纪 50年代中期至 2 0 0 0年期间人民币实际汇率状况 ,估计出人民币均衡实际汇率 ,进而测算了实际汇率错位状况。研究结果表明 :在计划经济时期 ,人民币实际汇率长期被高估。改革开放后 ,均衡实际汇率长期处于贬值状况 ,现实的实际汇率长期被低估。在亚洲金融危机期间 (特别是 1 997和 1 998年 ) ,人民币实际汇率出现了明显的高估。 1 999年这种高估状况得到部分缓解 ;2 0 0 0年出现了根本性好转。在现实中 ,1 999年以后中国出口的快速增长也证实了这一结论。

Real exchange rate and exchange rate policy in Hungary

Five real exchange rate indicators are computed to assess the international competitiveness of Hungarian industry. These indicators are explained in econometric equations by employment, unemployment, productivity, interest spread and real producer wage. Causality tests reveal that external performance has an impact on real exchange rates, and contributes to explaining real exchange rates. There is very limited scope for policy intervention to constrain the negative effects of capital inflows without incurring other costs.     

基于VAR的中国货币形势指数实证分析

本文根据1996～2007年我国短期实际利率、实际有效汇率和真实国内生产总值季度数据构建了我国近年来的货币形势指数,并运用VAR模型实证分析了我国货币形势指数比率。结果表明,汇率对产出变动的影响较大,而利率没有发挥应有的作用。因此,在当前我国宏观经济内外失衡的环境下,应以货币形势指数作为货币政策操作的参考指标,加快利率市场化进程,增强人民币汇率制度的灵活性。     

The Political Economy of Real Exchange Rate Behavior: Theory and Empirical Evidence for Developed and Developing Countries, 1960–2010

Empirical results of testing the PPP hypothesis have constantly shown that relative prices do not converge to the same level, either in the short or the long run. Therefore, the PPP explanation of the real exchange rate does not provide a reasonable measure of competitiveness at the international level. This article puts forth a different approach based on the works of Ricardo, Marx, Harrod and Shaikh. It argues that the real relative unit labor cost is the main factor explaining the long-run behavior of the real exchange rate. The second section of the article explains the theoretical underpinnings of our approach. The third section analyzes the role of the real interest rate differential in explaining real exchange rate misalignments. In the fourth section, we present a graphical analysis of the interrelation among the real effective exchange rate, the real unit labor cost ratio, the short-run real interest rate differential and the trade balance for 16 OECD countries, Taiwan and three developing countries for the period 1960–2010. The fifth section investigates the long-run relationship between the latter three indexes through co-integrating and error correction models using the ARDL–ECM framework. The last section provides our conclusions.     

What can Trigger the Resumption of Economic Growth in a Small Open Economy like Greece: Exports or Inward FDI?

The purpose of this article is to investigate the effect of exports and inward foreign direct investment (FDI) on economic development in Greece, in the long and short run, from 1980 to 2013. This study applies the Ng-Perron and DF-GLS unit root tests to determine the level of integration as well as the autoregressive distributed lag (ARDL) method to identify the long-run relationship. Our analysis confirms the long-run relationship between inward FDI, exports and national income. Our results imply that any policy by the Greek Government aimed at boosting economic development through exports will have to be considered for the long run since Greek authorities cannot rely on exports in the short run. However, inward FDI appears more efficient than exports as far as boosting economic progress in the short run.     

Analysis on the Option of RMB Exchange Rate Regime

This paper analyses four effects of pegging exchange rate regime： effects on government policymaking, nominal anchor, domestic currency appreciation expectation, and currericy speculative attacks. Based on this, the paper concludes that China should give up RMB pegging exchange rate regime at present, carry out RMB floating exchange rate regime in the long term and RMB exchange rate target zone regime in the mid and short term.     

Regime-switching purchasing power parity in Latin America: Monte Carlo unit root tests with dynamic conditional score

We suggest a Monte Carlo simulation-based unit root test of the purchasing power parity theory for Latin American countries. Under the null hypothesis, we use a Markov regime-switching (MS) model with unit root in the conditional location and MS volatility dynamics. Under the alternative hypothesis, the proposed test incorporates Markov regime-switching autoregressive moving average (MS-ARMA) plus MS volatility dynamics. Under both the null and alternative hypotheses, one of the volatility models estimated is Beta-t-EGARCH, which is a recent dynamic conditional score volatility model. We use data on real effective exchange rate time series for 14 Latin American countries. For each country, we estimate by Monte Carlo simulation the critical values of the unit root test. We provide an economic discussion of the unit root test results and also study the robustness of MS-ARMA plus MS volatility with respect to smooth transition autoregressive models with Fourier function.     

人民币汇率变动影响中国贸易条件机制研究

人民币汇率变动影响中国贸易条件及其机制是一个需要将理论与实证结合起来研究的问题,因为其中汇率变动对贸易条件的变化影响较大,衡量一国对外贸易中竞争能力的三类贸易条件均为反映资源配置效率及福利水平高低的指标。以人民币实际有效汇率变动的实证为例,分析汇率变动对贸易条件影响的内在机制,得出的结论是人民币实际有效汇率对中国价格贸易条件影响显著,对收入贸易条件影响不显著。     

Do exchange rate changes have symmetric or asymmetric effects on the demand for money in Turkey?

As a result of the research conducted by Nobel Laureate Robert Mundell (1963), most studies estimating the demand for money today do include the exchange rate in their specification to account for currency substitution. Previous studies that did this for the Turkish demand for money assumed that exchange rate changes do have symmetric effects on the demand for money in Turkey. In this article, we question this assumption. By using the nonlinear ARDL approach, we show that indeed exchange rate changes do have short-run and long-run asymmetric effects on the M1 demand for money. Introducing nonlinearity also yields a stable money demand.     

人民币行为均衡汇率及错位程度的测算研究:1978-2006

基于行为均衡汇率理论,应用多种计量经济方法对1978-2006年期间人民币实际汇率状况进行的实证分析结果表明:从名义汇率错位情况来看,1995年及以前的名义汇率都是高估的,1996-2005年的名义汇率基本上都是低估的,且低估程度在2000年达到顶点,然后逐渐下降;2005年约低估4.7%,但到2006年,受2005年人民币汇率改革的影响,名义汇率反而高估约0.9%.从实际汇率错位情况来看,1993年及以前的人民币实际有效汇率都是高估的,1994年以后,随着出口的快速增长以及美元的不断贬值,人民币实际有效汇率相对于行为均衡汇率低估程度总体上不断扩大,2005年约低估16.3%;到2006年,受2005年人民币汇率改革的影响,人民币实际有效汇率低估程度有所下降,约低估15.3%.     

Disorderly adjustments to the misalignments in the Korean won

This paper estimates the equilibrium exchange rates for Korea'sreal effective rates using Clark and MacDonald's (1999) behaviouralequilibrium exchange rate (BEER) approach. The estimation resultsuggests that the real exchange rate was substantially overvaluedduring the period prior to the currency crisis of 1997–98.The subsequent adjustment, however, was disorderly in the sensethat the real exchange rate overshot its long-run equilibriumvalue. There was also a large deviation from the BEER, indicatingthat the sharp depreciation was not an equilibrium phenomenon.
