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...

Much of Africa has not yet gone through a quot;demographic transitionquot; 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...

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...

A growing literature points to children's influence on parents' behavior, including parental investments in children. Further, previous research has shown differential parental response by socioeconomic status to children's birth weight, cognitive ability, and school outcomes - all early life...

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...

Caspi et al. (2002, 2003), Guo et al. (2008a), and Pescosolido et al. (2008) all claim to have demonstrated allele-by-environment interactions, but in all cases environmental influences are potentially endogenous to the unmeasured genetic characteristics of the subjects and their families. Thus,...

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...

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...

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...
