Measuring Human Capital Like Physical Capital: What Does it Tell Us?

In this paper, I develop a measure of human capital stock that is similar to measuring physical capital by its replacement cost. This measure builds on measures of average educational attainment of the labour force. While it is far from an ideal measure, it is an interesting complement to the educational attainment series and other existing measures of human capital accumulation. In cross-country panel regressions, use of this measure of human capital accumulation yields a positive and significant, but relatively small (about ten per cent) elasticity with percapita GDP growth. Unlike physical capital, the stock of human capital as a share of GDP increases with GDP. This is consistent with the Barro (1995) model of growth with non-mobile human capital and with some predictions of Romer's (1990) model of endogenous growth, but it is not consistent with the predictions of some other growth models.
