Human Capital Composition and Economic Growth

The objective of this paper is to analyze the effect of various compositions of human capital on economic growth. We construct alternative measures of human capital composition using five fields of study. In each instance, the measure represents the number of graduates in the respective field as a percentage of all graduates. The measures are as follows: agriculture human capital (AGR); high-tech human capital (TECH); business and service human capital (SERVICE); the humanities human capital (HUMAN); and health and welfare human capital (HEALTH). This paper uses the OLS and System-Generalized Method of Moments (GMM) models to explain differential rates of growth among developed and developing countries. The evidence indicates the significant effects of education and high-tech human capital on growth.
