This paper aims to examine the effects of exchange rate volatility on economic growth of West African English speaking countries. Macroeconomic data used for this study were obtained from World Bank Data Stream between 1980 until 2017 and analyzed using Stata 14 panel data regression analysis. The results obtained showed that the independent variable (real exchange rate) is statistically significant and negatively related to the dependent variable (GDP) in West African English speaking countries excluding time-invariant variables. This current study contributes empirically regarding the relationships between exchange rate volatility and economic growth of West African English speaking countries. From 1980From -2017. The findings of this study will help the countries under review and other nations in general to improve on monetary policy; it could be used by the central bank of West African English speaking countries as a guide for effective monetary policy.

This study seeks to test for the presence of asymmetric effect in the Nigerian Stock Exchange. In order to achieve the objective of the study, the researcher obtains the average market return, the equilibrium market returns generated by the risk factors of the APT, and then subjects them to asymmetric tests using the TAR-GARCH technique. Findings from the study reveal that equilibrium market return generated by pre-specified APT does not significantly respond to information asymmetry. This implies that is volatility does not really change with information. However, the equilibrium market return generated by statistical APT exhibits the presence of information asymmetry whereby the volatility of stock returns significantly responds to information. This reveals the presence of leverage effect in the Nigerian stock market whereby stock returns volatility increases with bad news but the volatility reduces with good or positive news. The researcher recommends that government agents in respect of this market should provide more adequate means of information diffusion into the market at zero cost to all participants.
