Industrial structure,competitiveness, and trade

This paper examines the effect of sector-specific growth on real exchange rates, competitiveness, and the trade balance. Growth and accumulation in export- and import-competing industries exert their primary effect on the trade balance, while the direct effect of accumulation in non-tradables is on the real exchange rate. Thus, exchange-rate policies that are incompatible with non-tradables equilibrium are bound to fail. Furthermore, growth policies with strong biases toward tradables are often inferior to more balanced strategies, due to their adverse implications for real-exchange- rate movements and the trade balance.     

理解中国的实际汇率:一价定律偏离还是相对价格变动?

本文利用1997年1月至2010年9月的数据对人民币实际汇率进行分解,发现可贸易品偏离一价定律因素可以解释实际汇率波动的60%—80%,而可贸易品与不可贸易品之间的相对价格波动只能解释实际汇率波动的20%—40%。这意味着研究人民币实际汇率需要更多地从可贸易产品出发,不应仅仅强调国内不可贸易品与可贸易品的相对价格变化。进一步的研究发现,可贸易品因素对于解释人民币实际汇率占主导的结论,与中国相对于其他国家的经济体发展阶段有关。但是,上述结论并不意味着传统的"巴拉萨-萨缪尔森"效应失灵。事实上,当在计量回归中控制可贸易品偏离一价定律因素以后,巴萨效应在中国显著成立。只不过,相对于可贸易品偏离一价定律因素,巴萨效应对实际汇率波动的影响是次要的。     

Product Variety and Real Exchange Rates: The Balassa-Samuelson Model Reconsidered

This paper introduces product variety into the Balassa-Samuelson model in order to extend the model of real exchange rate determination. With product differentiation, real exchange rates depend not only on the relative price of nontradables to tradables but also on relative prices among tradables. This paper identifies a new factor that determines the extent of variety, termed Infrastructural Technology, and that affects real exchange rates not through the relative price of nontradables but through relative prices among tradables. This paper also conducts empirical tests, and the results of these tests support the model. Received May 31, 2001; revised version received March 20, 2002 Published online: April 30, 2003     

The policy (in)effectiveness of government spending in a dependent economy

This paper analyses the policy effectiveness of government spending in a two-sector open economy whose output and expenditure is comprised of tradables and non-tradables. This framework reveals that government spending on either tradables or, more normally, on non-tradables widens the external deficit, yet how the real exchange rate behaves depends, in the first instance, on in which sector the public spending occurs. It also shows that, irrespective of where government spending falls, there appears to be no significant short run boost to overall output and hence employment a priori, although empirically actual impact would depend on the elasticities of tradable and non-tradable output with respect to the real exchange rate. Furthermore, fiscal stimulus is shown to be unambiguously ineffective if deemed unsustainable by foreign lenders, or implemented under a fixed exchange rate regime with limited capital mobility.     

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.     

The Law of One Price: A Canada/U.S. exploration

The paper examines whether arbitrage tends to equalize commodity prices for internationally traded homogenous products. It also investigates whether the increasing integration of North American markets has reduced price differences over time, and tests the validity of the so-called Law of One Price. We find that price differences for homogenous tradables between Canada and the U.S. are smaller than those for differentiated tradables and non-tradables, and are statistically insignificant over the period 1985 to 1999. We find no support for the notion that the increasing integration of North American markets due to trade liberalization has reduced price differences between Canada and the United States. Instead, the shifts in the price differences (expressed in the same currency) generally reflected fluctuations in the exchange rate. Canadian prices adapt with a lag to U.S. price changes that are brought about by changes in the exchange rate.     

THE REAL EXCHANGE RATE AND THE BALASSA–SAMUELSON EFFECT: THE ROLE OF THE DISTRIBUTION SECTOR

Abstract. This paper investigates the long‐run impact of the distribution sector on the real exchange rate. The main result is that an increase in the productivity and product market competition of the distribution sector with respect to foreign countries leads to an appreciation of the real exchange rate, similar to what a relative increase in the domestic productivity of tradables does. This contrasts with the result that one would expect by considering the distribution sector as belonging to the non‐tradable sector. One explanation may lie in the use of the services from the distribution sector in the tradable sector.     

Trade Imbalance and Domestic Market Competition Policy

This study investigates the effect of a country's suppression of competition in its market for nontradables. It assumes that the initial equilibrium is stationary and demonstrates that if competition is suppressed in a small country, the country's trade surplus increases in the short run. In the large country case, the same change creates an excess demand for future tradables and affects the relative price between present and future tradables. Using a two‐country model, the study shows that this price change redistributes real wealth from the country with a trade deficit to the country with a trade surplus.     

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.     

FDI,SECTORAL OUTPUT AND REAL EXCHANGE RATE DYNAMICS UNDER FINANCIAL OPENNESS

This paper adopts an alternative approach to the study of the impact of capital inflow on the real exchange rate by foremost, analysing the effect of FDI inflow on the ratio of tradables to nontradables, and then estimating the relationship between the tradable‐nontradable ratio and the real exchange rate, while accounting for the role of financial openness. Based on data for a group of developing countries, the findings show that an increase in FDI inflow is associated with a decrease in the tradable‐nontradable ratio, and that an increase in the tradable‐nontradable ratio leads to a depreciation of the real exchange rate; this effect being greater with an increase in financial openness. This suggests that an increase in FDI inflow could result in an expansion of the nontradable sector, which would be associated with a greater appreciation of the real exchange rate under a higher level of financial openness.     

True protection and the real exchange rate in a capital-rich developing country: some evidence for Saudi Arabia

This paper investigates how alternative measures of the real exchange rate respond to trade policy and terms of trade changes. It employs a modelling framework which endogenises the price of non-tradeable goods, and applies the model to price and real exchange rate data for Saudi Arabia for the period 1982–92. The results show that the popular propositions about the response of the real exchange rate to terms of trade or trade policy changes do not necessary hold. This is a consequence of the measure of the real exchange rate utilized, rather than a product of Saudi Arabia's capital richness.     

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.     

What Determines Real Exchange Rates? The Nordic Countries

The model derived in this paper yields testable implications concerning the long‐run co‐movements of real exchange rates, relative labor productivity, the trade balance and terms of trade. Countries with relatively higher output growth, trade deficits or improved terms of trade are found to have more appreciated real exchange rates, with the main channel of transmission working through the relative price of nontraded goods. Exogenous terms‐of‐trade shocks are found to be the most important determinant of long‐run movements in the real exchange rate for Denmark and Norway, while demand shocks account for most of the long‐run variance in the real exchange rate for Finland and Sweden.     

Asset prices, exchange rates and the current account

This paper analyses the role of asset prices in comparison to other factors, in particular exchange rates, as a driver of the US trade balance. It employs a Bayesian structural VAR model that requires imposing only a minimum of economically meaningful sign restrictions. We find that equity market shocks and housing price shocks have been major determinants of the US current account in the past, accounting for up to 30% of the movements of the US trade balance at a horizon of 20 quarters. By contrast, shocks to the real exchange rate have been less relevant, explaining about 9% and exerting a more temporary effect on the US trade balance. Our findings suggest that large exchange rate movements may not necessarily be the key element of an adjustment of today's large current account imbalances, and that in particular relative global asset price changes could be a potent source of adjustment.     

Intertemporal Substitution and Terms-of-Trade Shocks

The paper examines the relationship between transitory terms‐of‐trade shocks and private saving. Using a model allowing for nonseparability between the consumption of tradables and nontradables, the paper estimates the intertemporal elasticity of substitution while accounting for the intratemporal elasticity of substitution between the consumption of tradables and nontradables. Empirical analysis of data for five industrial countries indicates that in response to transitory terms‐of‐trade shocks, intertemporal substitution of consumption and intratemporal substitution of consumption between tradables and nontradables both have large effects on private saving.     

Short-Termism and the Dangers of Prior Announcement of Policy When There is Hysteresis in Trade and Competitiveness

It has been suggested recently that, in the presence of non-zero entry costs and where there is sluggish adjustment, 'over-shooting' of the real exchange rate and 'short-termist' behaviour by firms may exacerbate hysteresis effects in trade and the real exchange rate. The purpose of this paper is to show that, in special circumstances, hysteresis effects may in fact be reduced in these circumstances. In other words, short-run volatility of the real exchange rate and short-sighted behaviour may actually dampen trade and exchange rate hysteresis. Furthermore, by pre-announcing policy, governments may actually worsen hysteresis effects in trade and the real exchange rate.     

The long-run effects of the real exchange rate on employment and wages in Canadian manufacturing

ABSTRACT

The literature on real exchange rate effects on the labour market is dominated by short-run analysis showing that there is heterogeneity in the responses of firms or industries to a real exchange rate shock. Analysing data on Canadian manufacturing industries, I conclude that there is a common long-run equilibrium across all manufacturing industries controlling for their openness to trade after varying adjustments to a real exchange rate shock have taken place. This conclusion is important from the perspective of policy making because it helps to form expectations about the effects of a real exchange rate movement on the labour market. The results suggest that real appreciation leads to economically significant reductions in employment in manufacturing in the long run. Real wages decrease in industries that are highly engaged in international trade and somewhat increase in industries that are relatively closed to international trade. Both employment and real wages converge quickly to the long-run equilibrium.     

Nontraded Goods and Real Exchange Rates in a Multi‐Good Ricardian Model

The two‐country Ricardian trade model with discrete goods and uniform transport costs for tradable goods is applied to the decomposition of the real exchange rate into traded and nontraded components. The real exchange rate is driven almost entirely by changes in the productivity differentials in nontraded goods and also explains the Balassa–Samuelson effect of a lower cost of living in poor countries, but extraordinary transport costs for some nontraded goods are necessary to easily explain the Balassa–Samuelson effect.     

人民币实际汇率波动对中美贸易收支的影响——基于1990—2009年时间序列分析

基于协整理论、误差修正模型和格兰杰因果检验并根据中国和美国1990-2009年的季度数据,分析人民币实际汇率变动对中美贸易收支的影响.结果表明:影响中美贸易收支的主要因素包括美国的实际GDP、中国的实际GDP和人民币实际汇率,且三者的影响力次第减弱,中美贸易也存在明显的J曲线效应.因此,改善中美贸易失衡应扩大中国内需、调整业口结构和改革人民币汇率制度.     

The Malaysian Real Trade Balance and the Real Exchange Rate

The cointegration technique is used to examine the long‐run and short‐run relationships between the real Malaysian trade balance with the real exchange rate, domestic and world incomes. The results suggest that a real ringgit exchange rate depreciation improves the trade balance in the long run. World and domestic incomes are also found to be important determinants of trade balance. The significance of world income on trade balance indicates that Malaysia is prone to external shocks. An error‐correction model is then estimated to study the short‐run dynamics of the effects of exchange rate. The impulse response analysis shows that the effect of exchange rate on the trade balance lasts for about three years. A devaluation of ringgit will initially improve the trade balance, albeit small, after which the trade balance starts to deteriorate, and then improves again suggesting that there exists a delayed J‐curve.
