This paper assesses the trade-off between acquiring specialized skills targeted for a particular occupation and acquiring a package of skills that diversifies risk across occupations. Individual-level data on college credits across subjects and labor-market dynamics reveal that diversification...

This paper incorporates assignment frictions and sector-specific training into the Roy model of occupational choice. Assignment frictions represent the extent of the market whereas differences in sector-specific training reflect worker specialization. This framework thus captures Adam Smith's...

This paper studies the impact of permanent and transitory shocks to income on parental investments in children. We use panel data on family income, and an index of investments in children in time and goods, from the Children of the National Longitudinal Survey of Youth. Consistent with the...

Over the last two centuries, many countries experienced regime transitions toward democracy. We document this democratic transition over a long time horizon. We use historical time series of income, education and democracy levels from 1870 to 2000 to explore the economic factors associated with...

High-skilled emigration has been found to affect developing economies via different channels. With a calibrated general equilibrium framework, this paper finds that the short-run impact of brain drain on resident human capital is extremely crucial, as it does not only determine the number of...

This Paper attempts to draw lessons for the New Economy from what economists know about technology dissemination and economic growth. It argues that what is most notable about the New Economy is that it is knowledge-driven, not just in the sense that knowledge now assumes increasing importance...

This Paper examines the education literature through the lens of sorting. It argues that how individuals sort across neighborhoods, schools and households (spouses), can have important consequences for the acquisition of human capital and inequality. It discusses the implications of different...

We propose to model individual educational investments as a rational decision, maximizing expected utility, conditional on some characteristics observed by the student, under the combined risks affecting future wages and schooling duration. Assuming that students' attitudes toward risk can be...

What are the consequences of resource-based regional specialization, when it persists over a long period of time? While much of the literature argues that specialization is beneficial, recent work suggests it may be costly in the long run, due to economic or political reasons. I examine this...

We study how barriers to competition - such as, restrictions to business start-up and strict enforcement of covenants or IPR - affect the investment in knowledge capital when contracts are not enforceable. These barriers lower the competition for human capital and reduce the incentive to...
