The objective of this study is to evaluate the different channels wherein human capital affects income per worker level and growth. 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 wherein human capital affects income is due to the complexity of the relationship between these two variables. Therefore, if we rule out any channel we can incur in model specification errors.
human capital; creation of technology; diffusion of technology
