At least one of every five marriages is consanguineous (between couples who are second cousins or closer) in the Middle East and North Africa, and the rate is higher than 50 percent in some parts of the world. Consanguineous marriage generates serious health problems for the offspring and...

We show that a calibrated dynamic skill accumulation model allowing for comparative advantages, can explain the weak (or negative) effects of schooling on productivity that have been recently reported (i) in the micro literature on compulsory schooling, ii) in the micro literature on estimating...

We estimate a dynamic model of schooling on two cohorts of the NLSY and find that, contrary to conventional wisdom, the effects of real (as opposed to relative) family income on education have practically vanished between the early 1980's and the early 2000's. After conditioning on a cognitive...

This paper analyzes immigration and outsourcing in a general-equilibrium model of international factor mobility. In our model, legal immigration of skilled labor is controlled through a quota, while outsourcing is determined both by the firms in response to market conditions and through...

In this paper, we propose a theoretical model to study the effect of income insecurity of parents and offspring on the child's residential choice. Parents are partially altruistic toward their children and will provide financial help to an independent child when her income is low relative to the...

Using a dynamic skill accumulation model of schooling and labor supply with learning-by-doing, we decompose early life-cycle wage growth of U.S. white males into four main sources: education, hours worked, cognitive skills (AFQT scores) and unobserved heterogeneity, and evaluate the effect of...

There is a growing trend of buying homes among the single population in the U.S. This trend has been referred to as "Going Solo" and is particularly evident among women who are the focus of our study. In this paper we investigate the hypothesis that homeownership probabilities can be affected by...

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...

This short essay reviews Gary Becker's contributions and influence in health economics. It was originally prepared for the collection of short papers in honor of Gary Becker that is scheduled to appear in the inaugural issue of the Journal of Demographic Economics

A two-year randomized evaluation shows that the effectiveness of multi-tasking men- tors on schooling outcomes crucially depends on their training. While a standard training modality in highly marginalized communities in Mexico generates null results, enhanced training yields sizable treatment...
