LA CONVERGENCE DES ÉCONOMIES: UNE APPLICATION DU MODÈLE DE SOLOW AUX PAYS DE L’UEMOA
THE CONVERGENCE OF SAVINGS: AN APPLICATION SOLOW THE MODEL TO WAEMU COUNTRIES

Summary/Abstract: This article examines the economic convergence across the UEMOA area over the period 1965-2011. We use the usual methodology based on cross-sections for judging or not the existence of a convergence. On the economic plan, emphasis is placed on the Ordinary Least Squares (OLS) method and tests of constraints on the coefficients. The results indicate that the absolute convergence is not accepted for the sample selected. It is howether accepted when the are underestimeted GDP countries and those to GDP overvalued. Furthermore, the conditional convergence is also refused for all the countries of the sample because according to data, the annual growth rate of the output per worker and the average annual savings rate would not be conditioning variables of state. These results reveal the existence of other important endogenous factors such as economic policies adopted by these countries and the heterogeneity of natural capital. The harmonization of national economic policies must continue with integrating projects however instances of regional decisions could reflect on a productive integration with variable geometry, based on a territorial and industrial conception.
