Cálculo e análise da produtividade total dos fatores do Brasil com ênfase no papel do estoque de capital público

Abstract

This work investigates the process of Brazilian economic development between the years of 1950 and 2008. To this end it's calculated a series of Total Factor Productivity (TFP) using the growth account method and using as theoretical base a growth model were there are complementary relation between public and private capital, besides the inclusion of human capital as effective labor augmenter. The series of TFP is utilized to elaborate two growth decompositions, one based on the common production function and the other based on a modified version of the production function. Each decomposition has as results the median annual contribution to the increase in productivity of labor of each one of the four factors of productivity and also percentage of contribution of each of those factors in the same periods. That information is vital for the characterization of Brazilian development process, for the gathering of the trajectory of efficiency in usage of factors of production and for the investigation of the role of public capital in long term growth and in specific periods. We found that human capital is the factor with biggest contribution to the growth in the period as whole, that TPF increases until 1980 were it starts to declined until 2003 and that public capital have a small but substantial contribution.
