Abstract

Cette étude accrédite l'hypothèse suivant laquelle le niveau d'efficacité micro-économique conditionne largement le degré d'efficience des politiques de régulation des marchés agricoles. L'illustration porte sur la réforme de la PAC qui escompte un freinage de la progression des rendements céréaliers. Nous utilisons une approche non paramétrique pour mesurer les inefficacités proprement techniques. La résorption totale de ces dernières, estimées à partir d'échantillons d'exploitations céréalières, conduirait à une augmentation de 11% des rendements. D'autre part, si l'on suppose une situation d'efficacité-prix pour les producteurs, la baisse des rendements apparaît sans ambiguïté mais avec la mise en évidence d'effets amortisseurs. Cette communication a également été présentée à la session de printemps de la SFER les 13 et 14 mai 1993 et au VIIème congrès de l'Association Européenne des Économistes Agricoles, à Stresa les 6 et 7 septembre 1993.
