I show that in a conventional Ramsey model, between one-fourth and one- half of income differences across countries can be explained by a single factor: The steady-state effect of large, persistent differences in national average IQ on worker productivity. These differences in cognitive...

We utilize county-level data to explore the roles of different types of human capital accumulation in U.S. growth determination. The data includes over 3,000 cross-sectional observations and 39 demographic control variables. The large number of observations provides enough degrees of freedom to...

In an environment where children's time has an economic value and employment opportunities for educated workers are scarce, parental investments in their children's education may not be driven entirely by poverty and credit constraints. We offer evidence that children's participation in child...

Human capital plays an important role in the theory of economic growth, but it has been difficult to measure this abstract concept. We survey the psychological literature on cross-cultural IQ tests, and conclude that modern intelligence tests are well-suited for measuring an important form of a...

This chapter analyzes the effects of an aging population on individual skill choices and the production structure by means of a dynamic general equilibrium model with overlapping generations and probabilistic aging. The model allows for capital-skill complementarity, which strongly affects the...

The aim of this paper is to explore the relationship between wages, human capital and investment in financial assets with risky returns at the individual level. To explore this relationship from an international perspective, we analyse individual level data from the British Household Panel...

We explore the effect of bullying at school on the educational attainment of a sample of individuals drawn from the British National Child Development Study (NCDS). Our empirical findings suggest that school bullying has an adverse effect on human capital accumulation both at and beyond school....
