Real Exchange Rates and Fundamentals: Evidence from 15 OECD Countries

In an extended Balassa–Samuelson model, long-run real exchange rates are determined by relative productivity and terms of trade. We present evidence of systematic long-run relationships between these fundamental variables and real exchange rates in a data set covering 15 OECD countries from 1960 to 1996. High relative productivity is associated with real exchange rate appreciations in most cases. There is less support for the hypothesis that the terms of trade affect equilibrium real exchange rates.     

Sources of Real Exchange Rate Volatility in Africa: The Case of ECOWAS*

Abstract: This study examines the impact of (real) demand shocks, (aggregate) supply shocks, and monetary shocks on real exchange rates in 13 West African countries. We observe that the real demand shocks explain most of the fluctuations in real exchange rates in all these countries. Accordingly, policymakers should adopt a careful demand management strategy by controlling government expenditure and taxes.     

Generalized purchasing power parity and the case of the European Union as a successful currency area

This article uses multicountry purchasing power parity (PPP) tests to study the success of the European monetary system (EMS) in creating a successful currency area for a stable European monetary union. If the EMS has sufficiently integrated the fundamentals within the European Union, then real exchange rates between member countries will share a common stationary trend when denominated by a common outside currency. Previous research using two-country PPP tests have been inadequate in explaining the nonstationary nature of real exchange rates between the EMS countries and nonmember countries. The use of generalized PPP tests can show that even though individual exchange rates within the EMS may appear to be nonstationary with respect to outside countries, some of them will combine to form a currency union with a stable stationary trend.     

Do Real Exchange Rates Follow a Nonlinear Mean Reverting Process in Developing Countries?

In an effort to fight relatively high inflation, many developing countries try to manage their nominal exchange rates through official intervention. In addition, developing countries tend to have high transportation costs, tariffs, and nontariff barriers. These factors are among the sources of generating nonlinearity in real exchange rates and hence some nonlinear adjustment toward purchasing power parity (PPP) in developing countries. In this paper, we employ monthly real effective exchange rate (REER) data of 88 developing countries and test the null of nonstationarity versus an alternative of linear stationarity by the means of a conventional unit root test and compare the results with those obtained from a new test in which the null is the same but the alternative hypothesis is nonlinear stationarity. The latter test supports the PPP theory in more developing countries compared with the former test, suggesting that nonlinear adjustment toward PPP in developing countries is an important phenomenon. Reported country characterizations indicate that reversion in REER occurs more often for high-inflation countries and for countries with high flexibility in their exchange rates.     

Bilateral Trade in the Asia-Pacific: A Case Study for Australia, USA, Japan and Singapore

This analysis of bilateral trade involves four Asia-Pacific nations (USA, Japan, Singapore and Australia) on a quarterly data set 1977 to 1994. The reduced-form model applied here derives from a structure which accommodates income, real exchange rate and real-balance effects. We find that bilateral balances between these countries are not cointegrated with some potential determinants, in particular real exchange rates. In the short run, appropriately defined, we find that Singapore’s trade with the USA and Japan is influenced by real exchange rates; Australian-Japanese and Australian-US trade is influenced by real income and real-cash-balance effects but not real exchange rates while USA-Japanese bilateral trade is influenced only by real-cash-balance effects. The general conclusion is that real exchange rates have only limited effects on these selected Asia-Pacific bilateral trading patterns, while real-balance and income effects have a greater impact over the short run.     

Mean Reversion of Real Exchange Rates in High-Inflation Countries

We test for mean reversion in real exchange rates using data from five countries, four of which have experienced episodes of high inflation. Using monthly data for Argentina, Brazil, Chile, Colombia, and Israel, we find that a stochastic unit root model is typically appropriate (Brazil is the exception). Kalman filter estimates of the stochastic unit roots show sharp deviations from unity associated with high inflation episodes. This suggests that stochastic unit root models are a more appropriate way to model mean reversion in real exchange rates for high inflation countries than models with fixed rates of mean reversion.     

Currency Misalignments in the BRIICS Countries: Fixed Vs. Floating Exchange Rates

In the present paper we attempt to investigate whether the real effective exchange rates of the BRIICS countries, namely Brazil, Russia, India, Indonesia, China and South Africa, converge or not to their equilibrium levels. Our analysis is based on the use of an external balance model as well as the implementation of recent panel cointegration techniques. Our evidence indicates the existence of a valid long-run relationship between the real effective exchange rate, the net foreign assets, the GDP differential and the real interest rate differential for each of the six countries of our sample. Furthermore, our empirical results imply that after the adoption of a free floating exchange rate regime by Brazil, Russia, India, Indonesia and South Africa and the liberalisation of the Chinese exchange rate policy that took place during the last decade, currency misalignments have been gradually reduced, leading the real effective exchange rates of the respective currencies very close to their equilibrium levels.     

Assessing convergence to purchasing power parity: A panel study for ten OECD countries

Assessing Convergence to Purchasing Power Parity: A Panel Study for 10 OECD Countries. — The paper analyzes whether post-Bretton Woods real exchange rates of ten OECD countries are nonstationary so that long-run purchasing power parity (PPP) can be considered to hold. A test procedure is proposed which treats the various real exchange rates as a panel but still allows to assess the rate of convergence to PPP for each pair of currencies separately. It is shown that long-run (tradables-) PPP holds between all countries analyzed. Rates of convergence to PPP, however, are found to be quite different across countries. For most of the OECD countries convergence takes place faster than previously indicated.     

Decline in the persistence of real exchange rates,but not sufficient for purchasing power parity

The paper investigates the possibility of decline in the persistence of real exchange rates, or deviations from PPP. To this end, we test the null hypothesis of no decline in the PPP deviation persistence between two subsamples using a fractional integration framework. The test rejects the null at the 10% significance level for nine out of 17 countries, providing solid evidence for a decline in the persistence of real exchange rates. However, the decline is not sufficient for PPP, meaning we fail to reject the unit root hypothesis even in the latter period for all 17 countries. In addition, our rolling-window estimates show that the real exchange rate of many countries have experienced a sharp drop in their persistence once we use samples starting from the mid-1980s. Finally, we examine the relationship between the dynamics of PPP deviation persistence and several economic variables and confirm that the speed of convergence of PPP deviations is highly related to economic/financial integration and world economic stabilization.     

Real Exchange Rates,the Trade Balance and Net Foreign Assets: Long-Run Relationships and Measures of Misalignment

In this paper we estimate equilibrium exchange rates for 23 OECD countries and four less mature economies in a panel data setting. Our empirical analysis demonstrates significant links between the trade balance and net foreign assets, and between real exchange rates and the trade balance, rather than between real exchange rates and net foreign asset, as predicted by the model of Lane and Milessi-Ferretti (2002). Our study indicates that, in terms of the association between real exchange rates and trade balance, there is heterogeneity between the emerging market economies and the OECD countries. Finally, we construct various measures of exchange rate misalignment for all the exchange rates included in our panels.     

THE ROLE OF COMMODITY TERMS OF TRADE IN THE DETERMINATION OF THE REAL EXCHANGE RATES OF THE MEDITERRANEAN COUNTRIES

The aim of this paper is to investigate whether there exists a long‐run relationship between the real exchange rate and the commodity terms of trade in the so‐called Mediterranean or MENA countries. These economies are good candidates for this type of formulation, as are commodity exporting countries. Using cointegration techniques, we find long‐run relationships linking the real exchange rate and a commodity‐based measure of the terms of trade. Therefore, commodity terms of trade are a potential explanation for the apparent nonstationarity of MENA countries’ real exchange rates previously found in the empirical literature.     

Real Exchange Rates, Valuation Effects and Growth in Emerging Markets

We compare the relationship between net capital inflows, real exchange rate movements and growth for twenty emerging markets and twelve developed countries over the period 1985–2004. In developed countries low real exchange rates are associated with faster growth, but in emerging markets depreciations depress growth, even outside crisis periods, and are closely correlated with declines or reversals in net capital inflows. To investigate valuation effects of currency movements, we construct debt-weighted real exchange rate indices for emerging markets, which are more closely correlated with growth than trade-weighted indices.     

Misalignments of real exchange rates and the credibility of nominal currency bands

Misalignments of Real Exchange Rates and the Credibility of Nominal Currency Bands. — This paper analyzes a sticky-price target zone model in which realignment risk is modeled endogenously as a function of the degree of real exchange rate misalignments. The implications of the model are used to investigate the credibility of selected nominal ERM exchange rate bands. We find that a lack of credibility of the ERM currency bands occurs mostly in countries with substantial swings and persistent misalignments of real exchange rates. These findings suggest that the major real appreciations in some European bilateral real exchange rates between 1987 and 1992 have been pivotal in triggering the ERM currency crises of 1992 and 1993.     

Inflation Targeting in ASEAN‐10

The paper addresses the empirical question of whether economies that do not systematically target inflation (non‐inflation targeters) experience higher exchange rate volatility as compared with inflation targeters in 10 countries of the Association of Southeast Asian Nation (ASEAN) from 1990 to 2010. The paper examines the role of real exchange rate, exchange rate volatility and the reaction functions of central banks using dynamic panel estimation techniques. The results indicate that the output gap offers more useful information than the inflation gap in setting interest rates for inflation targeters, implying that the real term is more important than the nominal term. In turn, this suggests that an increase in interest rate can be wielded swiftly to reduce real gross domestic product and suppress inflation. The real exchange rate appears as a weaker determinant in setting interest rates for non‐inflation targeters. Inflation targeters experienced lower exchange rate volatility compared with non‐targeters in the ASEAN, which implies that implementation costs to their domestic economies may be marginally lower. Meanwhile, the non‐targeters follow a mixed strategy as both the inflation and real exchange rate are used as instruments to set the interest rates.     

China＇s Import-exchange Rate Linkage： Evidence from the China-bound Exports of Japan and Korea

This paper examines how the China-bound exports of Japan and Korea are related to exchange rates, motivated by the fact that processing trade makes up a large proportion of China＇s trade, and that Japan and Korea are the leading source countries for processing imports. Because processing imports are inputs for exports, the link between such imports and China＇s exchange rates are ambiguous. We estimate export functions that include China＇s RMB real effective exchauge rates （REER） along with bilateral real exchange rates （B RER） using Johausen ＇s cointegration method aud find that the RMB REER significantly affects Japanese and Korean exports to China, even more so than BRER in most cases examined. These two exchange rates appear in the export equations with opposite signs. Subsequently, we use the estimated model to illustrate the importance of accounting for a concurrent change in B RER when analyzing the effects of a hypothetical RMB revaluation on China＇s trade balances despite the apparently weak imports-B RER linkage.     

Estimating the equilibrium exchange rate of the Central and Eastern European acceding countries: The challenge of euro adoption

This study estimates the equilibrium real and nominal exchange rates for five Central and Eastern European (CEE) countries. A new approach is adopted, which combines the fundamental equilibrium exchange rate (FEER) with the behavioural equilibrium exchange rate (BEER) methodology. In a VAR-based 3-equation cointegration system, we estimate structural equations for internal and external balances and link them to the real exchange rate. The estimated misalignment is used to derive equilibrium nominal exchange rates. The sustainability of an ERM-II-type exchange rate regime is investigated on ex post data, and the credibility problem of fixing the currencies of CEE countries vis-à-vis the single European currency is analysed.

Inflationary shocks and real output growth in nine Muslim-majority countries: Implications for Islamic banking and finance

Low and stable inflation is important for maintaining the viability of Islamic banking and finance within a dual banking system. Inflationary shocks when transmitted to real output growth cause a shift of investment to fixed return products as a hedge against the uncertainty of returns on equity investment under Islamic profit-loss sharing contracts. This study examines the transmission of inflationary shocks to the real economy for nine Muslim-majority countries (Bahrain, Bangladesh, Egypt, Indonesia, Iran, Malaysia, Pakistan, Saudi Arabia, and Turkey) that have introduced Islamic banking, all except Iran within dual-banking systems. A structural vector autoregressive (SVAR) framework is deployed to understand macroeconomic relationships using annual data from the late 1970s to 2014. The key finding is that inflationary shocks affect real interest and exchange rates which in turn impact real output growth. The paper argues that the absorption of inflationary shocks in real interest and exchange rates is the outcome of rigidities in nominal interest and exchange rates within repressed financial systems. Policy regimes that allow for greater adjustment in nominal interest and exchange rates under a deregulated financial system would offer better shock absorption capacity which would lead to less volatility in inflation, real interest and exchange rates, and real output growth. The resulting more stable macroeconomic environment would be more conducive to the development of an Islamic financial sector that would promote economic growth.     

Nontradable Goods and the Real Exchange Rate

How important are nontradable goods and distribution costs to explain real exchange rate dynamics? We answer this question by estimating a general equilibrium model with intermediate and final tradable and nontradable goods. We find that the estimated model can match characteristics of the data that are relevant in international macroeconomics, such as real exchange rate persistence and volatility, and the correlation between the real exchange rate and other variables. The distinction between tradable and nontradable goods is key to understand real exchange rate fluctuations, but the introduction of distribution costs is not. Nontradable sector technology shocks explain about one third of real exchange rate volatility. We also show that, in order to explain the low correlation between the ratio of relative consumption and the real exchange rates across countries, demand shocks are necessary.     

Asian Currency Crisis and the Generalized PPP: Evidence from the Far East

The present paper investigates the effects of the Asian currency crisis of 1997–1998 on the generalized PPP between several real exchange rates of the Far East countries. Monthly log of real exchange rates of the currencies of Thailand, Malaysia, Indonesia, the Philippines and South Korea vis-à-vis the US dollar and the Japanese yen during 1990–2004 are applied in the investigation. Further tests are conducted between exchange rates vis-à-vis the Thai baht. Tests are conducted for periods before and after the crisis. Results from the Johansen method of multivariate cointegration show a substantial change in the relationship between these real exchange rates before and after the Asian currency crisis. This result is found using rates based on three currencies: US dollar, yen and baht.     

Exchange rates,stock prices,and money markets: evidence from Singapore

This paper uses a monetary approach to analyze the asymmetric asset-price movements (exchange rates and stock prices) in Singapore, a small open economy with managed exchange rate targeting. The Singapore dollar exchange rates vis-à-vis the developed countries’ currencies are negatively related to stock prices whereas the relationship between the Singapore dollar-Malaysian ringgit exchange rate and stock prices is positive instead. The pattern of asymmetry is explained by the relative exchange-rate elasticity of real money demand and real money supply and evidenced by the distributed-lag regression and VAR analysis. Furthermore, the distributed-lag regression of monthly data suggests that fiscal revenues as well as fiscal expenditures exert positive influences on stock prices.
