Economic Growth - Human Capital and Growth

Human Capital and Growth

One ubiquitous element of both theoretical and empirical analyses of economic growth is the role of human capital. The skills of the population enter into both neoclassical and endogenous growth models. The most commonly used measure of human capital is the level of school attainment in a country, building upon the data development of Robert Barro and Jong-Wha Lee. This measure of human capital, however, requires the strong assumption that what is learned in a year of schooling is the same across all countries. It also presumes that human capital is only developed in formal schooling, contrary to the extensive evidence that families, neighborhoods, peers, and health also contribute to the development of human capital. In order to measure human capital more accurately, Eric Hanushek and Dennis Kimko introduced measures of mathematics and science skills from international assessments into growth analysis. They found that quality of human capital was very significantly related to economic growth. This approach has been extended by a variety of authors, and the evidence indicates that economic growth is very closely related to the cognitive skills of the population.
