This paper aims to analyse whether the differences in trade performance between the countries of the West African Economic and Monetary Union (WAEMU) do not compromise their convergence. The empirical analysis is carried out using the GMM estimator and covers all eight WAEMU countries over the period 2011-2016. The results confirm the existence of conditional convergence with a slow speed of convergence. The results also show that a low volume of intra-WAEMU trade compromises their convergence.
