Abstract

[eng] Econometric modeling of a dual translog cost function shows that the prices of intermediates inputs and household earnings have dominant effects on farmers'technical choices. Productivity gains are supposed to be due essentially to technical progress incorporated in the intermediates inputs necessary to vegetal productions. Finally, it is shown that output growth sharing (especially in the case of animal productions) has increased the share of the intermediates inputs more than the shares of the other inputs, beside it did not have any positive effects on the family labor income. [fre] La formalisation économétrique d'une fonction de coût dual translogarithmique montre que ce sont les prix des consommations intermédiaires et la rémunération du travail familial qui exercent les effets prépondérants sur les choix techniques des agriculteurs. Les gains de productivité seraient essentiellement dus au progrès technique incorporé dans les consommations intermédiaires nécessaires aux productions végétales. Il apparaît en dernier lieu que le partage des fruits de la croissance de l'offre (notamment celle des productions animales), entre les intrants, a davantage favorisé la rémunération des consommations intermédiaires et n'a pas exercé d'effets positifs sur le revenu du travail familial.
