Is there a J-curve effect in Turkish services?

This paper explores the existence of the J-curve effect in Turkish services. The model of Bahmani-Oskooee (Rev Econ Stat 67:500–504, 1985), one of the most commonly employed model in the j-curve literature, is adopted. Using quarterly data from 1986: I to 1998: III, we find that, as a result of real depreciation of Turkish currency, YTL, services trade balance initially improves, then worsens and improves again in the short run. This is a pattern indicating that J-curve effect does not exist in Turkish services sector. We also find that depreciation of Turkish Lira improves the trade balance of the sector in the long run, a result consistent with earlier findings for the whole Turkish economy.     

Asymmetric effects of exchange rate changes on Turkish bilateral trade balances

Previous studies that have assessed the short-run and the long-run effects of exchange rate changes on Turkey’s trade balance with its major partners relied upon a linear adjustment process that could not find much support for favorable effects of exchange rate changes. In this paper, once we separate real appreciations from real depreciations via the partial sum concept and introduce nonlinearity into the estimation and testing procedure, we show that the effects of exchange rate changes are asymmetric. More precisely, while lira appreciation does not have any significant effects on Turkey’s bilateral trade balances, lira depreciation has significantly favorable effects on Turkey’s trade balance with its European partners (France, Germany, Italy, Portugal, and Great Britain).     

Asymmetric effects of exchange rate changes on the Malaysia-China commodity trade

Previous research that considered the response of the trade balance between Malaysia and China to exchange rate changes used a linear model and did not find any significant long-run link. Suspecting that the results suffer from aggregation bias as well as ignoring nonlinear adjustment of the exchange rate, we consider the trade balance of 59 industries that trade between the two countries and use a nonlinear ARDL model to show that almost a third of the industries are affected by ringgit depreciation against the yuan, in an asymmetric manner. The largest industry, which accounts for more than 25% of the trade, is found to benefit from ringgit depreciation while not being hurt by appreciation. In total, 15 industries that account for 40% of the trade enjoy this property.     

Industry trade between Canada and Mexico: Will a weakening peso help Mexican manufacturing in the long run?

Mexico has longed served as one of Canada's major trade partner, but the plunging peso has had drastic effects across North America. This study investigates the bilateral trade relationship between Canada and Mexico for 27 individual industries, from 1973 to 2006. Cointegration analysis shows that overall sensitivity to the real exchange rate is weak, but that the trade balances of certain manufacturing industries do indeed improve after a currency depreciation. The “J-curve” effect is present for certain electrical and mechanical industries, suggesting that the recent decline of the peso may currently be having a negative impact on Mexican trade—but that it might eventually be beneficial, particularly for the Machinery and Transport Equipment sector.     

Exchange Rate Adjustment in Partially Liberalized Economy

This paper develops a model of exchange rate determination in partially liberalized post-socialist economy that operates under soft budget constraints in nontradable sectors. The model captures the factors that determine the evolution of a country's external balance during the initial phase of economic liberalization. Three types of disturbances are the center of analysis: liberalization of trade and foreign exchange regime, devaluation, and price liberalization. We show that the real exchange rate appreciation may either improve or worsen the trade balance depending on the sources of this appreciation. Thus, we argue that the real exchange rate cannot reflect true country's competitiveness unless all sectors are equally exposed to hard budget constraints. The model implications are further analyzed through the empirical evidence on the relationship between the real exchange rate and trade balance in three selected East European countries.     

The J-curve dynamics of U.S. bilateral trade

Three earlier studies examined the impact of dollar depreciation on bilateral trade between the United States and her six largest trading partners. They used different methodologies that resulted in different outcomes. In this paper we consider 18 major trading partners of the United States and employ a relatively new method to investigate the short-run as well as the long-run response of the bilateral trade balance to currency depreciation. While as with previous research we are unable to discover any J-curve pattern in the short run, in the long run real depreciation of the dollar has favorable effects on the U.S. trade balance in most cases.

人民币实际有效汇率的分解和马歇尔—勒纳条件的修正

马歇尔-勒纳条件是探讨货币贬值改善贸易收支的规律,本文根据人民币实际有效汇率的特点,把它分解为美元有效汇率和人民币对美元汇率之积形式,在此基础之上,本文重新考察货币贬值改善贸易收支的条件,对传统的马歇尔-勒纳条件进行修正。从我们研究中可以看出美元实际有效汇率变化对马歇尔-勒纳条件修正的重要作用,这包括美元有效汇率对人民币汇率弹性和人民币在美元有效汇率中的权重的两种影响。另一方面,即使人民币实际有效汇率贬值存在“J”曲线效应,人民币对美元实际汇率贬值,“J”曲线是否存在还要依赖一定的条件。本文实证研究结果显示出口（或进口）与人民币对美元实际汇率、美元实际有效汇率指数和外国收入（或国内收入）之间存在着显著的协整关系,美元实际有效汇率和人民币对美元实际汇率也存在显著的协整关系。从弹性的变化来看,修正的马歇尔-勒纳条件成立,同时人民币对美元实际汇率贬值有利于改善贸易收支,美元实际有效汇率贬值会恶化中国贸易收支。而对“J”曲线效应的实证研究显示无论是人民币实际有效汇率,还是人民币对美元实际汇率贬值和美元实际有效汇率贬值,我国“J”曲线效应均不显著。     

Balance sheet effects and original sinners’ risk premiums

This paper describes an empirical model of country risk premiums and their determinants, relying on recent theories of balance sheet effects. We approach the latter by introducing a novel approach to country risk premiums that assumes that nominal exchange rates can move away from or towards equilibrium exchange rates, which allows exchange rate movements towards equilibrium to stimulate favourable competitiveness effects as opposed to adverse balance sheet effects. We investigate eight European emerging economies that suffer from “original sin” over the period 2001–2013, using the pooled mean group estimator of the dynamic panel error correction model. This methodology improves estimation efficiency and model performance, but also allows differentiation between long- and short-run country risk premium determinants. We find that, in the long run, country risk premiums increase in response to higher inflation and a higher total debt-to-GDP ratio, while they move in the opposite direction when the real GDP growth rate rises. Our results suggest that, in the short run, higher external debt service caused by exchange rate depreciation, i.e. the balance sheet effect, and market volatility tends to raise risk premiums, while higher international reserves and the federal funds rate tend to decrease them. Moreover, we show that the negative balance sheet effect is much stronger than the potentially favourable competitiveness effect, and that the rise in risk premiums is not due to the increase in the size of external debt, but to the larger debt burden represented by balance sheet effects.     

A disaggregated approach to test the J-Curve phenomenon: Japan versus her major trading partners

A limited number of studies have tested the J-Curve phenomenon using bilateral trade data between the United States and its major trading partners. In this paper, we test the J-Curve hypothesis by using quarterly bilateral data over the 1973–98 period between Japan and its nine major trading partners. We demonstrate that when aggregate data are used, there is no evidence of the J-Curve in the short run or any significant relation between trade balance and effective exchange rate in the long run. However, when bilateral data are employed, we find evidence of the J-Curve between Japan and Germany as well as between Japan and Italy. We also find that real depreciation of the yen has favorable long-run effects in the cases of Canada, the United Kingdom, and the United States.     

China''s exchange rate and the balance of trade

This paper examines the responsiveness of the balance of trade of the People's Republic of China to the real exchange rate. We find that, in both the short-run and the long-run, devaluation serves to improve the balance of trade. Using quarterly data for 1980:I to 1989:IV we show that the bulk of the response to devaluation occurs over a one year period, with noJ-curve effect. These results suggest that the two-tier price system and other measures to liberalize the Chinese economy have made the exchange rate an effective indirect tool for regulating trade.
