This study investigates the effect of human capital, using gross enrolment rate as a proxy, on labor productivity. It also investigates if a larger public effort in providing education opportunities would lead to a more efficient distribution of skills and therefore give a positive effect on labor productivity. We use a panel data approach to estimate an endogenous growth model on countries that are selected as to be reasonably similar. The main results are that growth in gross enrolment rate have a positive effect on labor productivity, while the level of government expenditure on tertiary education (measured as a percentage of GDP) has a negative effect on labor productivity.
