REAL GROSS DOMESTIC INCOME,RELATIVE PRICES,AND ECONOMIC PERFORMANCE ACROSS THE OECD

This paper uses OECD data to examine changes in labor productivity, real gross domestic product (GDP) and real gross domestic income (GDI), economic aggregates, and relative economic growth over time. Real GDI combines changes in production (real GDP) with a trading gain derived from relative price changes. The paper considers two sources of trading gains: the terms of trade, and the real exchange rate. For OECD countries, the terms of trade is the more important price ratio, making a contribution to real income growth that is, on average, an order of magnitude larger than the real exchange rate. Over long time periods, the most important source of real income growth is changes in production. Over shorter time horizons, however, the trading gain can make noteworthy contributions. Changes in aggregates like real private consumption, or the relative economic performance of nations, are shown to be particularly dependent on the trading gain during the large swings in resource prices that occurred post‐2002.     

The real effect of currency misalignment on productivity growth: evidence from middle-income economies

There have been interesting perspectives on the role of real currency misalignment in productivity growth. Whereas some studies warn against the destructive effect of real currency misalignment on productivity growth, others simply encourage it, at least, in the form of undervaluation. This paper documents evidence in support of the latter argument for 100 middle-income countries for the 1994–2010 period, using fixed-effects and generalized method of moments estimation techniques. The paper finds real currency misalignment to enhance productivity growth if it occurs as undervaluation; and to hamper productivity growth if it occurs as overvaluation. The paper also finds the impact of real currency misalignment on productivity growth to be symmetric, implying that the size of the impact is independent of the size of the misalignment. Moreover, the choice of the real misalignment measure may matter.     

Real exchange rate and productivity in a specific-factor model with skilled and unskilled labour

The present study develops a two-sector specific factor model in which capital is mobile between sectors. We assume that the traded (non-traded) sector uses skilled (unskilled) labour for production. The theoretical model reveals that the real exchange rate (RER) response to a productivity shock depends on the countries’ relative abundance of skilled labour: a rise in traded productivity leads to a higher RER appreciation in a country whose relative skilled labour rate is high. Using panel data, structural break tests confirm that the skilled versus unskilled labour ratio may be a significant splitting variable. In the long run, the relationship between productivity and RER may be positive or negative, as suggested by the theoretical model, depending on the country’s relative abundance of skilled labour.     

Purchasing power parity and country characteristics: Evidence from panel data tests

We examine long-run purchasing power parity (PPP) using panel data methods to test for unit roots in US dollar real exchange rates of 84 countries. We find stronger evidence of PPP in countries more open to trade, closer to the United States, with lower inflation and moderate nominal exchange rate volatility, and with similar economic growth rates as the United States. We also show that PPP holds for panels of European and Latin American countries, but not for African and Asian countries. Our findings demonstrate that country characteristics can help explain both adherence to and deviations from long-run PPP.     

China's economic growth and its real exchange rate

The shocks that underlie China's comparatively rapid growth include gains in productivity, factor accumulation and policy reforms that increase allocative efficiency. The well-known Balassa–Samuelson hypothesis links productivity growth in tradable industries with real appreciations. Yet it relies heavily on the law of one price applying for tradable goods, against which there is now considerable evidence. In its absence, other growth shocks also affect the real exchange rate by influencing relative supply or demand for home product varieties. This paper investigates the pre-conditions for the Balassa–Samuelson hypothesis to predict a real appreciation in the Chinese case. It then quantifies the links between all growth shocks and the Chinese real exchange rate using a dynamic model of the global economy with open capital accounts and full demographic underpinnings to labor supply. The results suggest that financial capital inflows most affect the real exchange rate in the short term, while differential productivity is strong in the medium term. Contrary to expectation, in the long term demographic forces prove to be weak relative to changes in the skill composition of the labor force, which enhances services sector performance and depreciates the real exchange rate.     

Elections, exchange rates and reform in Latin America

In this paper, we study the link between real exchange rate (RER) depreciation and elections in Latin America. Our contribution is threefold. First, we employ a statistical model that takes into account the pervasive conditional heteroskedasticity found in financial data and includes a wide range of macroeconomic variables as regressors. Second, we test whether the wave of central bank reform that swept the region has had any effect on the existence or strength of the electoral cycle in exchange rates. Third, we test an additional hypothesis, namely, that financial liberalization may also be an important variable explaining changes in electoral effects on the real exchange rate. In a panel of 9 Latin American countries with available macroeconomic data and a history of exogenous election dates, we confirm the previous findings that real depreciation intensifies after elections even when modeling the significant conditional heteroskedasticity in these data. We also show, for the first time in the literature, that post-election exchange rates are significantly less predictable. We go on to test whether central bank reform has influenced the way in which elections affect the RER in Latin America. If reform has been effective at reducing political manipulation of the exchange rate, then any relationship we see between elections and the RER before central bank reform should be mitigated in the post-reform era. We find that the relationship disappears after reform and that post-reform real exchange rates are also significantly less volatile. Finally, we show that financial liberalization seems to have a stronger effect on the conditional variance of the RER than does central bank reform, but reform has a stronger impact on the conditional mean.     

THE HARROD–BALASSA–SAMUELSON HYPOTHESIS: REAL EXCHANGE RATES AND THEIR LONG‐RUN EQUILIBRIUM*

Frictions and perturbations may influence currency values in the short run, but it is generally acknowledged that real‐exchange rates eventually settle toward equilibrium. The puzzle then is how gradually this parity is reached given the fluidity in foreign exchange markets. Persistent differences in the relative productivity of countries—a broad characterization of the Harrod–Balassa–Samuelson hypothesis—may help explain this puzzle. This article introduces methods to estimate equilibrium adjustment paths semiparametrically, and then sort how each of these components influences the dynamics of exchange rates. This is done in a dynamic panel setting by introducing novel local projections methods for cointegrated systems. Productivity shocks affect dynamics, and after adjusting for these factors, adjustment toward equilibrium is relatively rapid.     

The equilibrium real exchange rate and macroeconomic performance in developing countries

This article presents first estimates of the growth impact of the equilibrium real exchange rate (ERER) for a sample of 63 developing countries over 1970–2007. The results suggest that real exchange rate misalignment, not the level of the ERER, matters for macroeconomic performance in these countries.     

Exchange rate regime,real misalignment and currency crises

Based on 69 sample countries, this paper examines the effect of macroeconomic fundamentals on real effective exchange rates (REER) in these sample countries. Using the misalignment of actual REER from its equilibrium level, we have estimated the factors explaining the extent of currency over- or under-valuation. Overall, we find that the higher the flexibility of the currency regime, the lower is the misalignment. The estimates are robust to different sub-samples of countries. We then explore the impact of such misalignment on the probability of a currency crisis in the next period, indicating the extent to which misalignment could be used as a leading indicator of a potential crisis. This paper thus makes a new contribution to the debate on the choice of exchange rate regime by bringing together real exchange rate misalignment and currency crisis literature.     

The Real Exchange Rate and Growth in Emerging Markets: The Case of Zimbabwe

Zimbabwe has been facing growth and external competitiveness challenges, as shown by declining shares in global exports, high current account deficits, external debt and a widening productivity gap with South Africa. Estimates of the real equilibrium exchange rate reveal periods of sizeable misalignment, both prior to 2008 and under the current multicurrency regime. Misalignment has an asymmetric impact on growth. While overvaluation hampers growth, we have not found robust evidence that undervaluation would raise it. Replacing the multicurrency regime anchored in the US dollar by the South African rand would help reduce overvaluation and stimulate exports and growth. Under any currency regime, Zimbabwe needs to implement sound macroeconomic policies and an environment conducive to investment.     

Productivity Shocks and Real Effective Exchange Rates

This paper provides new insights into the relationship between exchange rates and productivity developments for European Economies. We focus on the question whether productivity changes have a long‐run impact on real effective exchange rates for a large number of European economies. Focusing on a sample period running from 1995 until 2013, we adopt a cointegrated vector autoregressive approach and distinguish between long‐run equilibrium, short‐run dynamics and long‐run impact of shocks. Our findings show that for several industrialized economies, real effective exchange rates and labor productivity are not related over the long‐run. A possible explanation for this result is that wage developments do not reflect increases in labor productivity to a large degree, which prevents a transmission to the real effective exchange rate through the price channel. The results for Central and Eastern European Countries are more encouraging since a positive impact of labor productivity on real effective exchange rate is frequently observed.     

Catching up: The role of demand, supply and regulated price effects on the real exchange rates of four accession countries

The main aim of this paper is to examine the exchange rate behaviour of a group of four transitional, EU accession countries, with a view to making policy recommendations regarding their full accession to the European Monetary Union. We employ a dynamic OLS panel estimator to investigate the relative importance of demand and supply influences on the exchange rates of these countries. Our analysis shows that both supply‐ and demand‐side effects are important for the accession countries, although their overall effect on inflation differentials and competitiveness seems to be small. An additional focus of the paper is the examination of the role that administrated, or regulated, prices and the productivity of the distribution sector play in the real exchange rate dynamics. Using a unique database we show that administrative prices have been a powerful force behind price and real exchange developments for our group of accession countries. The distribution sector is shown to have an independent effect on the internal price ratio over and above that generated by the Balassa–Samuelson effect.     

The Usual Suspects? Productivity and Demand Shocks and Asia–Pacific Real Exchange Rates

A productivity-based model of East Asian relative prices and real exchange rates is tested using calculated productivity levels for China, Indonesia, Japan, Korea, Malaysia, Philippines, Singapore, Taiwan, and Thailand. Time-series regressions of the exchange rate on relative productivity ratios indicate such a relationship for Japan, Malaysia, and the Philippines (and Indonesia and Korea when oil prices are included). Panel regression provides slightly more encouraging results when the panel encompasses a subset of countries (Indonesia, Japan, Korea, Malaysia, and the Philippines). Neither government spending nor the terms of trade appear to be important factors.     

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.     

Agricultural productivity,the real effective exchange rate,and structural change: Some evidence from Africa

Agriculture is thought to play a number of roles in the early development process. All of these roles involve fostering non‐agricultural development, in particular manufacturing. It is argued in this paper that agriculture plays a role that has hitherto been ignored. Specifically, if agricultural labor productivity increases faster than manufacturing labor productivity, the real effective exchange rate will depreciate. This depreciation of real effective exchange rate occurs because in very poor countries agriculture makes up the dominant share of both GDP and employment. The depreciation also makes it easier for a country to expand the production of tradables relative to nontradables, with manufacturing being the main tradable. This proposition, which as agricultural labor productivity increases relative to manufacturing labor productivity the real effective exchange rate depreciates, is tested using data drawn from 10 sub‐Saharan African countries.     

Does Productivity Growth Appreciate the Real Exchange Rate?*

Revisiting the time‐honored link between productivity growth and the real exchange rate, we find that higher labor productivity tends to appreciate the real exchange rate, consistent with the traditional view. Contrary to the traditional view, however, we find that the positive productivity effect is transmitted through the relative price between tradable goods, rather than through the relative price between tradables and nontradables. Moreover, higher total factor productivity is found to often depreciate the real exchange rate. These latter two pieces of evidence, combined with the conceptual strength of total factor productivity over labor productivity as a productivity measure, call for further refinement of the conventional view regarding the effect of productivity on the real exchange rate.     

Relationship between trade openness and economic growth in Latin America: A causality analysis with heterogeneous panel data

We empirically analyze the causality relationship between economic growth and international trade using new advancements in the econometric methodology for heterogeneous panel data applied to Latin American countries. First, we test for dependencies between the units of cross‐section (countries) and then we test for cointegration between growth and openness. Finally, we test for Granger causality using a heterogeneous panel data test. The results reject the hypothesis of general, unidirectional, and homogeneous relationship between trade openness and economic growth in Latin American countries as a group. However, considering heterogeneity, we found significant evidence of causality from trade liberalization to economic growth in Chile, Peru, Nicaragua, and Uruguay; we have found bidirectional causality in Mexico and Honduras; and a causal relationship from economic growth to trade liberalization in Colombia, Costa Rica, Guatemala, and the Dominican Republic.     

Managing real exchange rate for economic growth: Empirical evidences from developing countries

Abstract

This article analyses macroeconomic policies capable of influencing the long-run real exchange rate (RER). In this vein, it identifies economic policy tools that can devalue RER, covering a theoretical issue neglected by the economic literature, which argues that competitive exchange rate enhances growth. After discussing the “Trilemma,” we identify those variables that could affect RER without constraining monetary policy or exchange rate regime choice. In what follows, we model the probability of achieving an undervalued (small or large) RER for a sample of 14 developing countries from 1980 to 2010 (30?years) by applying econometric techniques for discrete choice and censored data. Afterwards, we compare the results for Latin American nations with Asian ones. They suggest that competitive exchange rate requires different approaches depending on the region. Moreover, Latin American countries need to take on additional policies so that interventions in the foreign exchange market become effective.     

Does Africa grow slower than Asia,Latin America and the Middle East? Evidence from a new data-based classification method

We address the question whether sub-Saharan African countries have lower average growth rates in real GDP per capita than countries in Asia, Latin and Middle America and the Middle East. In contrast to previous studies, countries are no a priori assigned to clusters based on geographical location. Instead, we propose a latent-class panel time series model, which allows a data-based classification of countries into clusters such that within a cluster countries have the same average growth rate. Our empirical results suggest that three clusters are sufficient to describe the different growth paths. Twenty-six African countries belong to the low growth cluster, but 8 African countries show growth rates comparable with many countries in Asia, Latin and Middle America and the Middle East.     

实际外部财富、劳动生产率与人民币实际汇率——基于跨期一般均衡理论的实证研究

本文首先构建关于实际外部财富、劳动生产率、贸易条件与实际汇率关系的跨时一般均衡理论模型,然后利用1981-2009年相关时间序列数据,检验中国实际外部财富、贸易条件以及国内外两部门劳动生产率对人民币实际汇率的影响。结果表明,从长期看,中国实际外部财富的急剧攀升会引发人民币实际汇率快速升值;中国贸易部门相对非贸易部门劳动生产率上升会促使人民币实际汇率升值,而国外贸易部门相对非贸易部门的劳动生产率提高则会降低人民币实际汇率,净效应表现为劳动生产率并不能解释20世纪80年代以来人民币实际汇率的长期波动;中国贸易条件对人民币实际汇率的影响不明显。短期内,中国实际外部财富对人民币实际汇率的作用关系与长期一致。根据上述结论,本文提出了保持人民币实际汇率相对稳定的政策建议。
