The persistence in real exchange rate: Evidence from East Asian countries

In this article, we examine the degree of persistence in monthly real exchange rate of six East Asian countries in relation to their two major trading partners, the United States and Japan, to study the validity of PPP for the 1976:01–2009:03 period. To investigate the persistency in real exchange rate series, we use sum of the autoregressive (AR) coefficients and the confidence interval for it using grid-bootstrap procedure recently developed by Hansen (1999). We have two findings: first, we find evidence for high persistency in real exchange rate in terms of the Japanese yen for five countries and for four countries in terms of the US dollar the for the full and pre-crisis sample periods. Second, for the post-crisis period, the presence of low persistency in real exchange rate supports PPP for three countries in terms of the Japanese yen and five countries in terms of the US dollar. These findings indicate that real exchange rate series of five East Asian countries are mean-revert based on their exchange rate policies and East Asian countries can form a currency union.     

Real Exchange Rate Variability: An Empirical Analysis of the Developing Countries Case

The purpose of this paper is to investigate the potential role of monetary and real factors in explaining real exchange rate variability in developing countries. For this purpose two indexes of real effective exchange rate variability that measure short-term and long-term variability were constructed for 30 countries. The results obtained, using a generalized least squares procedures on cross section data, indicate that real exchange rate variability has been affected both by real and monetary factors. In particular it was found that more unstable nominal exchange rate policies were reflected in higher real exchange rate instability in the short-run; more unstable domestic credit policies resulted in higher short-term real exchange rate variability; and more unstable external terms of trade also affected positively the degree of real exchange rate instability.

Real exchange rate dynamics in transition economies

The paper analyzes the phenomenon of real exchange rate appreciation that has characterized transition economies. It is shown that the real exchange rate—measured as the relative price of tradables in terms of non-tradables—is affected by adverse initial conditions and structural reforms only in the first 5 years of the transition process. After that period, the so-called Balassa–Samuelson effect seems to dominate the real exchange rate determination. The paper discusses the implications for exchange rate policy and concludes that while for countries of the former Soviet Union a flexible exchange rate regime seems desirable, for Central and Eastern Europe countries a stable exchange rate and even an early move to the adoption of the euro should be considered.     

Real and nominal effective exchange rates for developing countries: 1973:1-1997:3

The International Monetary Fund construct and publish real and nominal effective exchange rate data, mostly for developed countries. In this paper real and nominal effective rate data for developing countries are constructed. Application of the KPSS test to real effective rate data reveals that PPP holds in most countries.     

APPLICATIONS OF REAL EXCHANGE RATE ANALYSIS

This paper presents an approach for analyzing changes in the real exchange rate. It cites three views of the real exchange rate and outlines the complex forces that cause the rate to change. Using data from the International Monetary Fund's International Financial Statistics, the analysis then focuses on selected countries, each chosen because its experience reflects the operation of a principal force affecting the exchange rate. A summary of the experience of several countries during the 1970–1983 period illustrates the importance of the real exchange rate in the wake of inflationary episodes, oil crises, massive capital movements, and debt crises during that period. The analysis directs particular attention toward the central role that real exchange rate movements have played in the international debt crisis.     

Reserve Requirements and Real Exchange Rate Misalignments in Emerging Market Economies

A popular policy target in emerging markets is the real exchange rate as an undervalued real exchange rate is seen to enhance international competitiveness. Within an augmented Dornbusch model it is shown that the implicit tax of low remunerated reserve requirements represents an efficient tool to depreciate the real exchange rate. The model is empirically tested for a panel of Latin American, East Asian and Eastern European countries. Controlling for the impact of fiscal policies and direct capital controls, the reserve requirement tax significantly explains real exchange rate misalignments.     

Real and nominal effective exchange rates of African countries during 1971Q1–2012Q4

One of the macro variables that are included in most models is the exchange rate. Overall performance of a country’s exchange rate is measured by changes in nominal or real effective exchange rate (REER). These rates are constructed and published mostly for industrial countries by international organizations. Less developed countries have received little attention. In this article, the two rates are constructed for 21 African countries using quarterly data over the period 1971Q1–2012Q4. As an application, we use the REERs to show that even in Africa the movements of the real effective rates follow a nonlinear path.     

Nonlinear adjustment of the real exchange rate towards its equilibrium value: A panel smooth transition error correction modelling

We study the nonlinear dynamics of the real exchange rate towards its behavioral equilibrium value (BEER) using a Panel Smooth Transition Regression model framework. We show that the real exchange rate convergence process in the long-run is characterized by nonlinearities for emerging economies, whereas industrialized countries exhibit a linear pattern. Moreover, there exists an asymmetric behavior of the real exchange rate when facing an over- or an undervaluation of the domestic currency. Finally, our results suggest that the real exchange rate may be unable to unwind alone global imbalances.     

Exchange rates of oil exporting countries and global oil price shocks: a nonlinear smooth-transition approach

This paper models logistic and exponential smooth transition adjustments of real exchange rates for six major oil-exporting countries in response to different shocks affecting oil prices. The logistic form captures asymmetric and the exponential form symmetric adjustments in regards to positive and negative oil price shocks. We chose oil-exporting countries that do not peg their exchange rates. For most countries, we detect no statistically significant non-linearities for the adjustment process of real exchange rate returns, be they asymmetric or symmetric, in response to oil supply shocks, idiosyncratic oil-market-specific shocks, and speculative oil-market shocks. Exceptions are oil supply shocks in the UK and possibly Brazil, where exchange rates respond nonlinearly, though the effects are symmetric for both countries. On the other hand, global aggregate demand shocks, which are shocks not originating directly in the oil market, have nonlinear asymmetric effects on real exchange rate returns for Canada, Mexico, Norway and Russia, and nonlinear symmetric effects for Brazil and the UK.     

Real exchange rate misalignments

This paper investigates episodes of real exchange rate appreciations and depreciations for a sample of 85 countries from 1960 to 1998. A Markov Switching Model is used to characterize real exchange rate misalignment series as stochastic autoregressive processes governed by two states corresponding to different means and variances. Our main findings are: first, some countries present no evidence of distinct misalignment regimes; second, for some countries there is no RER misalignment in one of the regimes; and, third, for the countries with two misalignment regimes, the appreciated regime has higher persistence than the depreciated one.     

Stationarity of Asian real exchange rates: An empirical application of multiple testing to nonstationary panels with a structural break

This paper investigates the stationarity of the real exchange rates of the currencies for ten Asian countries against the US dollar during the pre-Lehman period. This paper explicitly investigates the presence of a structural break that occurred at unknown dates across countries and which may have been caused by the Asian financial crisis in 1997–1998. To identify which of the ten countries hold real exchange rate stationarity, that is, long-run Purchasing Power Parity, the resampling-based multiple testing proposed by Romano and Wolf (2005) is employed while dealing with possible cross-sectional correlation among the countries and avoiding the over-rejection of the null hypothesis or the multiplicity problem. Moreover, the paper examines the small-sample property of the multiple testing when there is a structural break in cross-sectionally dependent panels. Finally, the empirical results show that the stationarity hypothesis of the real exchange rate is significantly supported in some Asian countries.     

Real and nominal effective exchange rates for 22 LDCs: 1971:1–1990:4

The International Monetary Fund constructs and publishes the real and nominal effective exchange rates, mostly for developed but not less developed countries. This paper employs a method of constructing real and nominal effective exchange rate from the literature to produce quarterly data over the 1971–1990 period for 22 developing nations. As an application, the stationarity of real effective exchange rates are determined to establish the empirical validity of the Purchasing Power Parity Theory (PPP). The results reveal that PPP fails to hold for most countries.     

Excess volatility of real exchange rates in the EMS: some evidence from structural VARs

This paper argues that the effectiveness of the exchange rate mechanism (ERM) of the European Monetary System (EMS) should be gauged by its impact on the monetary component of real exchange rate variability. Nominal and real shocks are separated using a bivariate structural VAR applied to real exchange rate data of the six original member countries participating in the ERM and a control group consisting of Britain and the United States. The findings suggest that monetary shocks have been an important source of real exchange rate variability and that the ERM has been successful in reducing the incidence of monetary shocks across its member countries prior to the EMS currency crises of 1992–93, while being less successful thereafter.     

Exchange rate volatility and exports from East Asian countries to Japan and the USA

The purpose of this article is to investigate the impact of exchange rate volatility on exports in four East Asian countries (Hong Kong, South Korea, Singapore, and Thailand). Specifically, this article aims at determining whether the bilateral real exchange rate volatility between an East Asian country and its trading partner negatively affects the exports of the East Asian country. Considering the dominant roles of the USA and Japan as trading partners of those East Asian countries, this article focuses on the quarterly export volumes of East Asian countries to the US and Japan for the period from 1981 to 2004. Except for the case of Hong Kong's exports to Japan, cointegration tests and estimations of error correction models indicate exchange rate volatility has negative impacts on exports either in the short-run or in the long-run, or both. On the other hand, the real GDP of importing countries and depreciation of real bilateral exchange rates turn out, in general, to have positive effects. Of special interest is the finding that the impact of the exchange rate volatility does not show any stylized differences depending on whether the importing country is Japan or the USA, even though dollar invoicing dominates in East Asia.     

Real exchange rates in emerging economies

We analyse the role of various investment margins in explaining the real exchange rate appreciation recorded in European transition countries. We present a model that introduces a quality investment margin and show that the margin is needed for replicating the observed pace of real exchange rate appreciation.     

Nonlinearities in the real exchange rates: new evidence from developed and developing countries

This paper investigates nonlinearities in the dynamics of real exchange rates. We use Monte Carlo simulations to establish the size properties of the Teräsvirta-Anderson test, when the dynamics of the real exchange rate is influenced by an exogenous process. In addition, we show that a modified nonlinearity test, which includes additional right-hand-side variables, performs much better than the original in both Monte Carlo exercises and in the actual data on 1431 bilateral real exchange rate series. Finally, we investigate the dynamics of the real exchange rate for both developed and developing countries using the modified test for the recent floating period. In general, the results find a greater incidence of nonlinear dynamics for developing country real exchange rates.     

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.     

Sources of real exchange rate fluctuations in China

This paper reviews the evolution of China's real effective exchange rate between 1980 and 2003 and uses a structural vector autoregression model to study the relative importance of different types of macroeconomic shocks for fluctuations in the real exchange rate between 1985 and 2003. The structural decomposition shows that relative real demand and supply shocks account for most of the variations in real exchange rate changes during the estimation period. The paper also finds that supply shocks are at least as important as nominal demand shocks in accounting for real exchange rate fluctuations. In contrast, other studies that show that nominal shocks are more important in explaining real exchange rate fluctuations in industrial countries.

Are real exchange rates nonlinear with a unit root? Evidence on PPP for Italy: a note

In this article, we apply the recently developed threshold autoregression model to examine both linearity and stationarity of Italy's real exchange rate vis-à-vis her six trading partner (G6) countries. Our main finding is that Italy's real exchange rate is a nonlinear process that is not characterized by a unit root process for five of six trading partner countries. This provides strong support for purchasing power parity.     

Non-Traded Goods and Real Exchange Rate Fluctuations: A Structural VAR Analysis

Real exchange rate variance decompositions indicate that only a small fraction of real exchange rate movements can be attributed to changes in the relative price between traded and non-traded goods. This paper argues that those exercises, by ignoring the nature of the shocks behind real exchange rate changes, may be inadequate to measure the relative importance of non-traded goods prices. Instead, it proposes using a structural vector autoregression (SVAR) model to study the effects of shocks to the relative supply and relative demand for non-traded goods on the real exchange rate. The SVAR model is identified via long-run restrictions and is estimated for a group of advanced economies. The results indicate that for some countries, relative supply shocks can be a significant source of real exchange rate fluctuations.
