Abstract

The monetary policy conducted by the Central Bank of West African States (BCEAO) faces many challenges, including the need to fight against inflation, which is driven mainly by the volatility of commodity prices on international markets. It is also fall to common criticisms about the lack of economic growth objective in her mandate as developing countries central bank in among the poorest in the world. It therefore not immune to reflection on the existence of a dilemma "inflation-growth" it would, consciously or unconsciously involved. The aim of this paper is to demonstrate the existence of a non-linear relationship between inflation and the economic growth within the West African Economic and Monetary Union (WAEMU) and to determine the inflation threshold at which a trade-off between inflation and growth is effective. From a threshold effects dynamic panel model, the study shows that the optimal level of inflation in the WAEMU zone is 8.08%. This result raises the question of the relevance of the standard deduction of 3% under the convergence criteria of the WAEMU zone. In addition, the inclusion of such a result is likely to help the BCEAO in the definition and conduct of monetary policy.
