Abstract

Cet article tente de justifier l'hypothèse selon laquelle le niveau d'efficacité micro-économique conditionne largement le degré d'efficience des politiques de régulation de marché. Dans cette optique, nous proposons une analyse de l'évolution des rendements céréaliers suite à la réforme de la PAC en tenant compte de différents niveaux d'efficacité économique. Dans une première partie, nous supposons que les agriculteurs ne sont pas tous sur les frontières de production. A l'aide d'une approche non paramétrique, nous mesurons leur efficacité technique que ce soit à facteur terre variable ou quasi-fixe. Une croissance des rendements céréaliers semble alors possible si tous les producteurs résorbent leur inefficacité technique. Dans une seconde partie, nous supposons que tous les producteurs sont "profit maximizers". A l'aide d'une approche paramétrique, nous constatons une baisse des rendements céréaliers atténuée par quelques effets amortisseurs.
