Abstract

Le caractere omnipresent de l'heterogeneite en agriculture est une evidence, qu'il s'agisse de la taille des entreprises ou des techniques mises en oeuvre par les agriculteurs. Ce phenomene est a premiere vue surprenant pour un economiste, habitue a considerer que la concurrence selectionne automatiquement les tailles et les techniques les plus performantes. Il existe cependant une explication simple de la dispersion des dimensions d'exploitation: la fonction de production agricole serait homogene et de degre 1, ce qui impliquerait l'absence d'economies d'echelle. En ce qui concerne la variete des techniques, il faut, pour en rendre compte, faire intervenir l'interaction dynamique entre les facteurs fixes, l'epargne, et les niveaux de prix. Ces analyses ont des consequences pratiques. En particulier elles soulignent la difficulte d'elaborer une politique des structures capable d'atteindre ses objectifs sans depenses budgetaires enormes. Cet article, comme celui de la notice precedente, est largement inspire d'une communication au colloque de Malaga (voir ci-dessous).
