Research on the effects of Vietnam military service suggests that Vietnam veterans experienced significantly higher mortality than both non-Vietnam veterans and the civilian population at large. These results, however, may be biased by non-random selection into the military if unobserved...

Much of Africa has not yet gone through a "demographic transition" to reduced mortality and fertility rates. The fact that the continent's countries remain mired in a Malthusian crisis of high mortality, high fertility, and rapid population growth (with an accompanying state of chronic extreme...

Both health status and net worth can affect retirement decisions. In some cases, early retirement may be precipitated by a shock to an individual’s health and/or economic status. The authors examine how health and wealth shocks affect retirement decisions. They use data from the Panel Study of...

Genetic and environmental inputs may shape population health disparities in varying ways. In this article, we use unique variation involved in twin births to attempt to untangle how genetic and prenatal environmental variation may make different contributions to infant health among white and...

Washington (2008) finds that, controlling for total number of children, each additional daughter makes a member of Congress more likely to vote liberally and attributes this finding to socialization. However, daughters' influence could manifest differently for elite politicians and the general...

Prior researchers have deployed the Vietnam-era draft lottery as an instrument to estimate causal effects of military service on health and income. This research has shown that effects of veteran status on mortality and earnings that appeared shortly after the war seem to have dissipated by...

Prior researchers have deployed the Vietnam-era draft lottery as an instrument to estimate causal effects of military service on health and earnings. However, household and residential outcomes may be more sensitive to the psychological effects of military service. Using 2SLS analyses of the...

While it has long been known that genetic-environmental covariance is likely to be non-trivial and confound estimates of narrow-sense (additive) heritability for social and behavioral outcomes, there has not been an effective way to address this concern. Indeed, in a classic paper, Goldberger...

A genome-wide association study (GWAS) of educational attainment was conducted in a discovery sample of 101,069 individuals and a replication sample of 25,490. Three independent single-nucleotide polymorphisms (SNPs) are genome-wide significant (rs9320913, rs11584700, rs4851266), and all three...

Preferences are fundamental building blocks in all models of economic and political behavior. We study a new sample of comprehensively genotyped subjects with data on economic and political preferences and educational attainment. We use dense single nucleotide polymorphism (SNP) data to estimate...
