n Studies in Economics and Econometrics - Real exchange rate volatility and its effect on trade flows : new evidence from South Africa

This paper empirically re-examines the impact of real exchange rate volatility on South Africa's export flows to the United States for the period 1992:1 - 2004:4, using the two-country model of international trade. The exponential generalised autoregressive conditional heteroscedasticity (EGARCH) model is used to measure real exchange rate volatility. Cointegration and error- correction models are used to obtain the estimates of the cointegrating relations and the short-run dynamics, respectively. Further, variance decomposition analysis is used to show the dynamic adjustments of real exports to shocks in the fundamentals and the proportion thereof. The results obtained in this paper summarily provide evidence that real exchange rate volatility has a negative effect on real exports.
