The present paper examines the directional causality between export diversification and real exchange rate in the middle-income countries of Asia and Latin America over the period from 1995 to 2013. Additionally, we investigate asymmetries in the causality issue by examining the direction across trading partners.
Our empirical results show that there is a two-way causality between the two variables when we look at the sample as a whole. A causal link running from the real exchange rate to export diversification is consistent with the standard literature but it is not systematic at all. The reverse causation is very appealing and challenges the standard argument on exchange rate determination. When the causality issue is investigated by treating export markets differently, our findings at the aggregate level are confirmed in exports destined for the advanced countries. The analysis for ‘South-South’ trade only shows a unidirectional link from the real exchange rate to changes in export diversification. The same tests performed at the individual countries level reveal a heterogeneous causality across trading partners. 相似文献
This paper intends to examine the volatility spillover effect between selective developed markets including U.S., U.K., Germany, Japan and Hong Kong over the sample period from 1996 to 2011. We introduce a Markov switching causality method to model the potential instability of volatility spillover relationships over market tranquil or turmoil periods. This method is more flexible as no prior information on the changing points or size of sample window is needed. From the empirical results, we find the evidence of the existence of spillover effects among most markets, and the bilateral volatility spillover effects are more prominent over turmoil or crisis episodes, especially during Asia crisis and subprime mortgage crisis periods. Moreover, the distinct role of each market is also investigated. 相似文献
