Abstract: This paper examines the impact of real effective exchange rate uncertainty on aggregate exports of South Africa for the period 1986Q4-2013Q2. We use a bivariate framework where the structural vector autoregression is modified to accommodate bivariate GARCH-in-Mean errors. We find that exchange rate uncertainty has a significant and negative effect on exports. There is also evidence in our results that accounting for real effective exchange rate uncertainty amplifies the dynamic response of real exports to exchange rate shocks. Furthermore, real exports respond asymmetrically to negative and positive shocks to real effective exchange rate shocks of the same size.
