In the past decade, nearly 20 studies have found a strong, persistent pattern in surveys and behavioral experiments from over 40 countries: individual exposure to war violence tends to increase social cooperation at the local level, including community participation and prosocial behavior. Thus...

This paper estimates the effects of maternal malnutrition exploiting the 1959-1961 Chinese famine as a natural experiment. In the 1% sample of the 2000 Chinese Census, we find that fetal exposure to acute maternal malnutrition had compromised a range of socioeconomic outcomes, including:...

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...

The largest 20th-century increase in U.S. home ownership occurred between 1940 and 1960, associated largely with declining age at first ownership. I shed light on the contribution of coincident government mortgage market interventions by examining home loan benefits granted under the World War...

This paper examines the post-war strategies of Liberia and Sierra Leone to generate revenues from their natural resources. We document the challenges faced by the government of the two countries, contrasting measures taken to address these challenges as well as the outcomes. We complement the...

While its recent history of civil war, chronic poverty and corrupt governance would cause many to dismiss Sierra Leone as a hopeless case, the country's economic and political performance over the last decade has defied expectations. We examine how several factors--including the legacy of war,...

This study estimates the effect of deployment location and length on the risk of developing PTSD, relative to what it would be from the normal military operations. We use a random sample of activity-duty enlisted personnel serving between 2001 and 2006. We identify PTSD cases from TRICARE...

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...
