An extensive literature has documented a robust correlation between socioeconomic status--measured in a variety of ways--and health outcomes; however, much uncertainty remains regarding what causal processes underlie this association. The present paper builds on a growing literature that seeks...

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...

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...

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...

We introduce a novel use of genetic data for studying social influences on behavior: Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we deploy the distribution of genotypes in a given grade within a school to instrument the influence of peer smoking on...

Evidence on the relationship between political contributions and legislators' voting behavior is marred by concerns about endogeneity in the estimation process. Using a legislator's offspring sex mix as an exogenous variable, we employ a two-stage least squares estimation procedure to predict...

Since at least T.H. Marshall, scholars have recognized military service as a form of sacrifice that warrants compensation from the state. Indeed, some see the very genesis of the modern welfare state as compensation for wartime sacrifice. War-widow pensions, expansion of the franchise, and...

Studies of online dating suggest that physical attraction is a key factor in early relationship formation, but say little about the role of attractiveness in longer-term relationships. Meanwhile, assortative coupling and exchange models widely employed in demographic research overlook the...

Recently, the sex of child has been widely used as a natural experiment and shown to induce change of the allegedly stable political predisposition, however, prior results have been contradictory: in the U.K., researchers found that having daughters leads to parents favoring left-wing political...

Research is needed to understand the extent to which environmental factors mediate links between genetic risk and the development of smoking behaviors. The Vietnam-era draft lottery offers a unique opportunity to investigate whether genetic susceptibility to smoking is influenced by risky...
