Capital humano e crescimento: impactos diretos e indiretos

The objective of this study is to evaluate the different channels in which human capital affects income level and growth and to use a proxy of human capital variable that incorporates quantitative and qualitative aspects of this factor. The human capital proxy that will be used is years of schooling (h) times HDI (Human Development Index) and h times HDI squared. HDI utilization is to measure countries degree of development. The assumption is that the more developed a country is, the better is its system of human capital formation. The empirical analysis is based in a model that incorporates several channels in which human capital affects the rate of income per worker growth: 1) improving the marginal productivity of labor; 2) through creation of technology; and 3) diffusion of technology. The consideration of several channels in which human capital affects income is due to the complexity of the relationship between these two variables. Therefore, if we consider only some channels we can incur in model specification errors.
