Abstract

This paper analyses the impact of technological change on Brazilian agricultural output and input mix from 1970 to 1985. We utilize an econometric model that considers two activities (vegetal and animal activities) and three inputs (labor. land and capital). It was observed in all period (1970 to 1985) can output bias in direction to vegetal production against animal production. It caused a bias in direction on labor and capital utilization and saving land. This paper also shows different behaviors in small periods, as 1970/75, 1975/80 and 1980/85.
