We exploit a volcanic “experiment" to study the costs and benefits of geographic mobility. We show that moving costs (broadly defined) are very large and labor therefore does not flow to locations where it earns the highest returns. In our experiment, a third of the houses in a town were...

In this paper we use data from the Retirement History Survey (RHS) to examine the relationship of some sociodemographic and economic variables to morbidity and mortality. Since the RHS is a longitudinal survey, we are able to study current health conditioned on prior health as well as the more...

In this paper, another aspect of optimizing behavior is considered. Specifically, it asks whether variations in levels of attained schooling across groups can be explained by a model that assumes that capital markets are perfect and that individuals maximize wealth. The logic of the analysis...

This paper examines the transmission of human capital from parents to children using variation in parental influence due to parental death, divorce, and the increasing specialization of parental roles in larger families. All three sources of variation yield strikingly similar patterns which show...

Recent advances have led to the discovery of specific genetic variants that predict educational attainment. We study how these variants, summarized as a linear index -- known as a polygenic score -- are associated with human capital accumulation and labor market outcomes in the Health and...

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...

There has long been interest in the extent to which effects of social stratification extend and persist across generations. We take a novel approach to this question by asking whether birth order and sibling group size in the parental generation influences the educational attainment of their...

We examine the impact of educational attainment on fertility and mating market outcomes. Using a regression discontinuity design, we exploit an extension of the compulsory schooling age from 15 to 16 in 1972 in the UK. The change was binding for a quarter of the population. Simple plots of the...

This paper discusses (a) the role of cognitive and noncognitive ability in shaping adult outcomes, (b) the early emergence of differentials in abilities between children of advantaged families and children of disadvantaged families, (c) the role of families in creating these abilities, (d)...

The stylized fact that individuals who come from families with more children are disadvantaged in the schooling process has been one of the most robust effects in human capital and stratification research over the last few decades. For example, Featherman and Hauser (1978: 242-243) estimate that...
