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 uses newly collected archival evidence to examine various aspects of the geographic performance of American labor markets before the Civil War. Much of the paper addresses the evolution of regional differences in real wages, of interest to economic historians because they speak to the...

Debilitating events could leave either frailer or more robust survivors, depending on the extent of scarring and mortality selection. The majority of empirical analyses find frailer survivors. I find heterogeneous effects. Among severely stressed former Union Army POWs, which effect dominates 35...

Miguel, Satyanath and Sergenti (2004) use rainfall variation as an instrument to show that economic growth is negatively related to civil conflict in sub-Saharan Africa. In the reduced form regression they find that higher rainfall is associated with less conflict. Ciccone (2010) claims that...

A recent paper by Burke et al. (henceforth "we") finds a strong historical relationship between warmer- than-average temperatures and the incidence of civil war in Africa (Burke et al. 2009). These findings have recently been challenged by Buhaug (2010) who finds fault with how we controlled for...

We employ a regression discontinuity design based on close elections to estimate the rents from a seat in the U.S. congress between 1850-1880. Using census data, we compare wealth accumulation among those who won or lost their first race by a small margin. We find evidence of significant returns...

We examine the long-run consequences of ethnic partitioning, a neglected aspect of the Scramble for Africa, and uncover the following regularities. First, apart from the land mass and presence of water bodies, historical homelands of split and non-split groups are similar across many observable...

The US Civil War provides researchers a unique opportunity to identify wartime leaders and thus to test theories of leadership. By observing both leaders and followers during the war and forty years after it, I establish that the most able became wartime leaders, that leading by example from the...

Building social tables in the tradition of Gregory King, we develop new estimates suggesting that between 1774 and 1800 American incomes fell in real per capita terms. The colonial South was richer than the North at the start, but was already beginning to lose its income lead by 1800. We also...

How do nationalistic media affect animosity between ethnic groups? We consider one of Europe's deadliest conflicts since WWII: the Serbo-Croatian conflict. We show that, after a decade of peace, cross-border nationalistic Serbian radio triggers ethnic hatred towards Serbs in Croatia. Mostly...
