Time-varying regional integration of stock markets in Southeast Europe

In an attempt to assess the impact of currency depreciation on the trade balance, recent studies are employing disaggregated trade data to avoid aggregation bias. However, since import and export prices are not available at disaggregated level, recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate. This study explores the experience of Malaysia. Bilateral inpayments and outpayments models are estimated between Malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration. The results show that while real depreciation of the ringgit has short-run effects, in the long-run it increases Malaysia's inpayments from only five trading partners.     

Towards solving the PPP puzzle: evidence from 113 countries

Several different approaches have been followed by researchers to test the validity of Purchasing Power Parity (PPP). Since the introduction of the unit-root tests, researchers have applied a battery of these tests to determine whether the real exchange rates are stationary. If the answer is in the affirmative, PPP is validated. While application of the standard augmented Dickey–Fuller test has not provided much support for PPP, a test that incorporates nonlinearity in the rates has. Under both tests, however, the null of nonstationary is tested against the alternative of stationarity. In this article, when we switch the null with the alternative and apply Kwiatkowski et al. (1992 Kwiatkowski, D, Phillips, PCB, Schmidt, P and Shin, Y. 1992. Testing the null hypothesis of stationarity against the alternative of a unit root. Journal of Econometrics, 54: 159–78. [Crossref], [Web of Science ®] , [Google Scholar]) test, we provide relatively more support for the theory, getting closer and closer towards solving the PPP puzzle.     

The J-curve in the emerging economies of Eastern Europe

Devaluation or depreciation of a currency worsens the trade balance before improving it, resulting in a J-curve pattern. A new definition of the hypothesis implies a short-run deterioration combined with the long-run improvement. By using monthly data over the January 1990–June 2005 period from 11 east European emerging economies, most of which are the new European Union (EU) members or the EU candidate countries, this article uses the bounds testing approach to cointegration and error-correction modelling and finds empirical support for the J-curve hypothesis in three countries of Bulgaria, Croatia and Russia. The results have important implications for policymakers involved in economics in terms of using exchange rate policy as a policy device to achieve real convergence toward EU standards.     

Impact of exchange rate uncertainty on commodity trade between US and Sweden

Previous studies that investigated the effects of exchange rate uncertainty on the trade flows of Sweden employed aggregate trade data either between Sweden and the rest of the world or at bilateral level between Sweden and her major trading partners. In this article, we disaggregate the trade data and employ the import and export data from 87 industries that trade between Sweden and the US. We find that exchange rate volatility has significant short-run effects on the trade flows between the two countries in almost two-third of the industries. However, the short-run effects are translated into the long-run effects in one-third of the cases. Furthermore, the real depreciation of krona against the dollar was found to have favourable effects on the overall trade balance between the two countries.     

The impact of economic and monetary uncertainty on the demand for money in emerging economies

By introducing uncertainty, monetary volatility and economic volatility are said to make the public cautious, hence increase their cash holdings or their demand for money. On the other hand, because of monetary and economic uncertainty if the public seek safer assets than money, they may hold less cash. In the absence of any paper testing for the impact of economic and monetary uncertainty on the demand for money in emerging economies, this article fills the gap by considering the experiences of six Central and Eastern European emerging economies and four other emerging economies. We found that the impact is transitory in most countries. Moreover, money demand is found correctly specified and stable in most countries, suggesting that policy based on monetary targeting could still be effective despite significant output and monetary uncertainty.     

The J-curve: evidence from commodity trade between UK and China

China is often accused of manipulating its currency to gain international competitiveness. Previous studies have tried to address this issue by investigating the impact of yuan depreciation on China’s trade balance. Not only have they failed to establish the link between the Chinese exchange rate and its trade balance with the rest of the world but also between China and her major trading partners. In this article, we consider the China–UK trade balance and disaggregate their trade flows by commodity. Out of the 47 industries considered, we show that the real depreciation has favourable short-run effects in most industries. However, the short-run effects last into the long run only in seven cases.     

US–Indonesia trade at commodity level and the role of the exchange rate

Previous studies that assessed the impact of currency depreciation on inpayments and outpayments of Indonesia with her major trading partners did not find much significant results, especially in the trade with the United States. We wonder whether insignificant link between the real rupiah-dollar rate and Indonesia’s inpayments and outpayments with the United States is due to aggregation bias. To answer this question, we disaggregate the trade flows between the two countries by commodity and consider the sensitivity of inpayments of 108 US exporting industries and outpayments of 32 US importing industries from Indonesia. We find that most industries respond to exchange rate changes in the short run. In the long run, however, 32 inpayments schedule and 17 outpayments schedule are significantly affected. A 1% real depreciation of the dollar was found to improve US trade balance by 1.8%.     

How stable is M2 money demand function in Japan?

The cointegrating property of the demand for money in Japan has been investigated by several researchers who have provided mixed results. None has investigated its stability. In this paper we employ the ARDL approach combined with CUSUM and CUSUMSQ tests to show that not only M2 is cointegrated with income and interest rate, but the estimated relation is stable.     

The J-Curve at industry level: Evidence from Sweden–US trade

Previous research that investigated the impact of real depreciation of kronor on Swedish trade balance used trade data either between Sweden and the rest of the world or between Sweden and each of her trading partners. Not much support was provided for a significant effect, especially in the case of Swedish–US trade. In this paper we consider the trade flows between Sweden and the US one more time and try to disaggregate the data by industry. We consider the trade balance of each of the 87 industries that trade between the two countries and investigate the short-run and the long-run effects of real depreciation of kronor on each industry's trade balance. While we find short-run significant effects in the majority of the industries, the short-run effects last into the long-run favorable effects only in 23 of 87 industries.
