RESUMO

Using data from the Agricultural Census of 1995-96 and the Demographic Censuses of 1991 and 2000, this dissertation first estimate a Cobb-Douglas production function. The value of production is calculated in order to control the effect of regional prices. Traditional factors (labor, land, fertilizers and capital) and human capital (years of schooling and market knowledge) are used as explanatory variables in the production function. The economic model is a simultaneous equations system that considers both decisions to produce and maximize profits. Results of the proposed economic model are obtained by using the three-stage least squares (3-SLS) method due to presence of heteroskedasticity. Afterwards, total productivity factor (TFP) is estimated to each of the Brazilian states and the relative contribution of human capital is analyzed.
