Produtividade Total dos Fatores: revisão da literatura e uma aplicação exploratória para a cultura do milho usando os dados dos censos agropecuários

Abstract

This study aims to contribute to the understanding of productivity in Brazilian agriculture and proposes a reflection on the debate of total factor productivity. For this, it was decided, first of all, to discuss productivity measures, particularly measures of total factor productivity and then provide estimates of total productivity in agriculture in Brazil and worldwide. A preliminary estimate of this methodology was also proposed of total factor productivity of corn using the Tornqvist index. The goal is to review the theoretical and empirical literature on total factor productivity in agriculture and calculate partial and total yields in corn to the Brazilian states. Although most of the results in the calculation of total yield for corn in Brazil were not consistent, the general conclusion of the literature was, both Brazilian agriculture as agriculture worldwide, regardless of the methodology used, tended to growth of total factor productivity.
