Conteúdo: 	Using farmers data comprising the Brazilian agricultural census of 2006, we fit a stochastic frontier model in the presence of endogeneity. The endogenous variable affecting efficiency is the probability of negative net income. Additionally we investigate the effects of technical assistance and agricultural research in efficiency. Production is modeled in the Cobb-Douglas family with three inputs: expenditures on labor, on land, and on other technical inputs. The response is gross income. Technological inputs are dominant, followed by labor and land. Research and technical assistance contribute significantly to reduce inefficiency and the probability of negative net income contributes positively to inefficiency.
