This paper examines the effects of a massive salt iodization program on human capital formation of school-aged children in China. Exploiting province and time variation, we find a strong positive impact on cognition for girls and no effects for boys. For non-cognitive skills, we find the...

This paper examines the impact of the Anglophone Conflict in Cameroon on human capital accumulation. Using high-quality individual-level data on test scores and information on conflict-related violent events, a difference-in-differences design is employed to estimate the conflict's causal...

Recent empirical studies question the conventional wisdom about the importance of education for growth. We test the hypothesis that this may be the case if human capital is diverted from growth-promoting activities to rent-seeking activities that are socially useful to reduce the negative...

India's colonial legacy and linguistic diversity give English an important role in its economy, and this role has expanded due to globalization in recent decades. It is widely believed that there are sizable economic returns to English-language skills in India, but the extent of these returns is...

We estimate the impact of schooling on monthly earnings from 1950 to 2000 in Romania. Nearly constant at about 3-4% during the socialist period, the coefficient on schooling in a conventional earnings regression rises steadily during the 1990s, reaching 8.5% by 2000. Our analysis finds little...

Estimates of the effect of education on GDP (the social return) have been hard to reconcile with micro evidence on the private return to schooling. We present a simple explanation combining two ideas: imperfect substitution and endogenous skill-biased technological progress and use cross-country...

This paper has two main objectives. First, it assesses and measures the gaps in the stock of human capital across the world. It presents how effectively different regions are improving their stock of human capital, and how long it will take for developing countries to catch up with the current...

When types of workers are imperfect substitutes, the Mincerian rate of return to human capital is negatively related to the supply of human capital. We work out a simple model for the joint evolution of output and wage dispersion. We estimate this model using cross-country panel data on GDP and...
