Capital humano y productividad en microempresas

The hypothesis that human capital increases productivity is tested using data from a sample of low value-added microenterprises. A special attribute of this paper is the join treatment of formal learning or training in education institutions, and informal training by experience of the owner in the firm management. Following previous studies, the relation between human capital and productivity is determined by estimating production functions with the inclusion of dummy variables to control for formal education and informal training by experience. Evidence of the linkage of human capital and productivity is reported. It is also reported that both types of investment in human capital have asymmetrical contribution to productivity, where the impact of experience is predominant. This allows concluding that the long-run existence of the firms in the sample is explained by the accumulation of experience in the management. Returns to education occur primarily for technical education and are lower than those generated by experiential learning in the firm management.
