Does exchange-rate volatility depress export flows: The case of LDCs

In the area of international trade, few studies have examined whether increases in exchange-rate volatility depress trade flows of LDCs. The aim of this paper is to investigate empirically the impact of exchange-rate volatility on the export flows of 10 developing countries over the quarterly period 1973-98. The econometric analysis exploits the theory of cointegration, given the obvious nonstationarity of the data. Estimates of the cointegrating relations are obtained using Johansen's multivariate procedure. Evidence of stability of the cointegrating space is examined using Hansen's [1992a] tests. Short-run dynamic modelling is accomplished using the error-correction technique, and the stability test results are obtained using Hansen [1992b] tests. In conformity with theoretical considerations, the results indicate that increases in the exchange-rate volatility exert a significant negative effect upon export demand in both the short-run and the long-run in most of the countries studied. These effects may result in significant reallocation of resources by market participants. (JEL F14, F31 ).
