Since the mid-1980s, growth theorists have increasingly focused on human capital as a source of long-run economic growth. Recently, however, a number of studies have documented that the social returns of human-capital investment are fairly small, implying that the contribution of human capital...

This paper calculates new measures of human capital. Contrary to the existing literature, they are based on realistic rates of return to education, which are allowed to vary substantially across countries and to some extent over time. The new measures perform well in regression analysis...

This paper provides a new measure of human capital using PISA and PIAAC surveys, and mean years of schooling. The new measure is a cohort-weighted average of past PISA scores (representing the quality of education) of the working age population and the corresponding mean years of schooling...

An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit...

This article analyzes the effect of public policy intervention in the production of health capital on fertility, private investment in children's health and education and human capital accumulation. I have used a growth model with endogenous fertility, in which the usual parental trade-off...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate micro-founded fertility and schooling into an otherwise standard R&D-based growth model....
