The role of human capital in economic development Evidence from aggregate cross-country data
Using cross-country estimates of physical and human capital stocks, we run the growth accounting regressions implied by a CobbPDouglas aggregate production function. Our results indicate that human capital enters insignificantly in explaining per capita growth rates. We next specify an alternative model in which the growth rate of total factor productivity depends on a nation’s human capital stock level. Tests of this specification do indicate a positive role for human capital.
