The abandonment of the fixed exchange rate systems has caused exchange rate movements to become arnmajor concern for traders, policy makers and researchers. Numerous studies have been conducted torndetermine whether exchange rate volatility affected international trade flows. Nevertheless, no generalrnconsensus has been reached as to the magnitude and direction of the impact of exchange rate volatility onrntrade flows.rnThis paper investigates the impact of exchange rate volatilities on the agricultural exports of Sub SaharanrnAfrican countries. Twenty nine sample SSAcountries were selected for the period 1996-2008. Estimationrnis made using random effects model, difference generalized methods of moments (GMM) and systemsrnGMM. Volatilities of the official exchange rate of SSA countries was generated using GARCH (1,1) andrnARCH models.rnThe Standard gravity model augmentedby variables which affect the trade between the SSA countries andrnthe major trading countries is estimated. Exchange rate volatilities is found to have a negative andrnsignificant impact on the agricultural exports of the SSA countries across the different estimationrntechniques. Trade policies that are designed to increase exports might create uncertainty in the exchangernrate and ultimately end up reducing exports. The main lesson drawn from the study is, SSA countriesrnshould have a stable exchange rate policyrnKey words: Exchange rate volatilities, gravity model, system GMM, GARCH , ARCH
