Real and nominal effective exchange rates in MENA countries: 1970–2004

The main purposes of this article are 3-fold. First, we construct measures of real and nominal effective exchange rates for 14 Middle East and North African countries over the 1970–2004 period. Second, we test the validity of the Purchasing Power Parity (PPP) by applying the ADF and KPSS tests to the real effective exchange rates. Finally, we employ the bounds testing approach to cointegration and error-correction modelling to show that nominal devaluation leads to real devaluation in the short-run as well as in the long-run in many of the countries.     

Revisiting purchasing power parity in G6 countries: an application of smooth time-varying cointegration approach

This study revisits purchasing power parity (PPP) for the G6 countries (i.e., Canada, Italy, Japan, France, Germany, the UK) using smooth time-varying cointegrating approach, proposed by Park and Hahn (Econom Theory 15:664–703, 1999). Using monthly data over the 1971M1–2013M12 period, our empirical results indicate that PPP holds in two out of six countries (i.e., France and Germany).     

The effects of currency fluctuations and trade integration on industry trade between Canada and Mexico

Since studies of North American trade flows tend to focus on the United States as the main trading partner, trade between Canada and Mexico has received relatively little attention. Here, we examine bilateral trade flows for 62 Canadian export industries to Mexico and 45 import industries from Mexico to assess the effects of currency fluctuations and trade integration on these individual trade flows. We find that Mexico’s largest export industries respond to depreciation more than Canada’s largest export industries do. Both countries’ trade flows are influenced even more by trade integration. Since there is evidence of strong intra-industry trade between these two countries, we can attribute this effect to the exploitation of economies of scale.     

On the impact of financial development on income distribution: time-series evidence

Financial market development is said to have equalizing or unequalizing effects on income distribution. Previous research used cross-sectional and panel data and provided mixed results. Suspecting that they suffer from aggregation bias, we adhere to time-series data and error-correction modeling technique and address the issue one more time in each of the 17 countries for which we have time-series data. In 10 counties, short-run effects of financial market development on income distribution were found to be equalizing. In five countries, the effects were unequalizing. However, the equalizing effects lasted into the long run only in three countries of Denmark, Kenya and Turkey.     

Inequality and growth in the United States: is there asymmetric response at the state level?

A previous study that tried to assess the impact of economic growth on income inequality in the U.S. used state-level data and an ARDL panel model to conclude that economic growth worsens income inequality in the U.S. In this article, we use the same data set but an ARDL time-series model applied to each state in the U.S. to show that the above conclusion is only valid in 20 states. Additionally, we use a nonlinear ARDL approach to show that the effects are asymmetric in the short run as well as in the long run. Significant long-run asymmetric effects reveal that in 28 states both an increase and a decrease in real output have worsened income distribution.     

Asymmetric effects of exchange rate changes on the demand for money in China

In order to account for currency substitution, the majority of recent studies relating to the specification of the demand for money include the exchange rate as another determinant of the demand for money. However, those who have estimated the demand for money in China have been unable to find any significant effects of exchange rate changes on the demand for money by the Chinese. We show that this is due to the assumption that exchange rate changes have symmetric effects. Once depreciations are separated from appreciations of the yuan, those exchange rate changes are shown to have significant effects on the demand for money in China, but in an asymmetric manner.     

Currency depreciations and the U.S.–Italian trade balance: Industry-level estimates

As one of the indebted Southern European countries that have put pressure on the Euro in recent months, Italy would benefit from a reduction in its external trade deficit. One channel could be through a weakening of its currency—which would only work if the Euro depreciated against the currency of an outside importer, such as the U.S. dollar. This study examines the response of the trade balances of 106 individual industries to such depreciations, using annual data and applying cointegration analysis. We find that only 19 industries register a long-run improvement, with these concentrated in miscellaneous manufactures (SITC sector 8). Two major products in the automotive industry—petroleum and road motor vehicles, show evidence of a “J-curve” effect.     

Exchange‐Rate Risk and Japanese–Thai Industry Trade

Over the past decade, many papers have studied the effects of exchange‐rate volatility on international trade, particularly at the bilateral level for large numbers of individual industries. This is necessary because the underlying theory is ambiguous and because earlier papers failed to uncover significant results at a higher degree of aggregation. This paper examines the case of Japan and Thailand over the period from 1970 to 2010. We find that slightly more than half of 117 export industries and 54 import industries are affected by volatility in the short run. In the long run, 6 export and 2 import industries are affected positively, and 22 export and 9 import industries are affected negatively. Small Japanese export industries are more likely to be negatively affected, while imports show no differences regarding industry size. In a sectoral analysis, we find some evidence that Japanese exports of manufactures and certain machinery and transport equipment might be relatively more affected by the exchange‐rate risk. Raw material imports are least affected. These findings therefore suggest which industries might benefit most by a policy promoting a stable yen.     

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.     

Relative Responsiveness of Trade Flows to a Change in Prices and Exchange Rate

A country can restrict her imports by imposing tariffs and stimulating her exports by providing subsidies. The same goal could be achieved through devaluation. One policy question that we face is the time it takes for either policy to affect the trade flows. We investigate here the relative responsiveness of the trade flows to a change in relative prices versus to a change in exchange rate. After estimating an error-correction version of import and export demand functions for nine industrial countries, unlike earlier studies that employed non-stationary data, our findings indicate that there is no specific answer and trade flows of different countries react differently.
