Trade liberalization and supply response of edible oils in west african economic and monetary union (WAEMU) countries ; Libéralisation commerciale et réaction de l'offre des huiles alimentaires dans les pays de l'Union Economique et Monétaire Ouest Afrique (UEMOA)
Local production of edible oils in the WAEMU's countries is no longer a credible defense line against imports. This reality contrasts with the objectives of agriculture policy and WAEMU's Common External Tariff (CET) which are supposed to protect Community production. Thus, under the light of the economic literature and based on empirical data, we used simultaneous equations for each country of WAEMU, panel data and gravity equations with panel data to determine the impact of trade liberalization on supply of edible oils in WAEMU's countries.The results obtained converge towards the same conclusion: the confrontation of objectives of protecting local production and trade openness policy with the coherence's tests reveals some inconsistencies and contradictions. Thus, WAEMU fails to reconcile the Union's trade openness objectives with the protection objectives of edible oils producers. Trade liberalization policies have tended to favor a disintegration of the productive structure and disruption of trade architecture. Thus, the supply of edible oils shows two contradictory reactions with regard to the trade liberalization within the WAEMU's countries: a depressive reaction displayed by the production and an explosive reaction displayed by the imports which are attracted by re-export rents. However, these rents are mirages that reserve destructive economic implications with the adoption of ECOWAS'CET. ; La production locale des huiles alimentaires ne constitue plus une ligne de défense crédible face aux importations dans les pays de l'UEMOA. Cette réalité contraste avec les objectifs de la politique agricole et du tarif extérieur commun (TEC) de l'UEMOA censés protéger la production communautaire. Ainsi, sous l'éclairage de la littérature économique et en se basant sur des données empiriques, nous avons utilisé les équations simultanées par pays de l'UEMOA, les équations des données de panel et les équations gravitationnelles en données de panel pour déterminer l'impact de la libéralisation commerciale sur l'offre ...
