What preferences motivate the severity of terrorist attacks? I investigate how Boko Haram terrorists adjust their fatalities when unexpectedly deprived of public attention, relative to Al Shabaab terrorists, that were not deprived of public attention. Losing public attention raises the severity...

Can participation in financial markets lead individuals to re-evaluate the costs of conflict, change their political attitudes and even their votes? Prior to the 2015 Israeli elections, we randomly assigned Palestinian and Israeli financial assets to likely voters, and incentivized them to...

This paper provides an empirical exploration of the “rice theory of culture” which implies that rice cultivation promotes a culture of cooperation and peace. Using fine-grained, cross sectional data geocoded at 0.5 degree latitude by 0.5 degree longitude, I investigate whether rice...

This research explores the historical roots and persistent effects of the division of labor in pre-modern societies. Exploiting a novel ethnic-level dataset, which combines geocoded ethnographic, linguistic and genetic data, it advances the hypothesis and establishes empirically that population...

This paper examines the impact of urban violence on the standardized test scores of public school students in Medellin. I use the school-level variation in exposure to local homicides for years 2004-2013 in a model that includes school and year fixed effects, allowing me to control for the...

The world's poor -- and programs to raise their incomes -- are increasingly concentrated in fragile states. We review the evidence on what interventions work, and whether stimulating employment promotes social stability. Skills training and microfinance have shown little impact on poverty or...

A theory is introduced to systematically explain autocracies' diverse experiences with taxation. State power relative to citizens' capacity for violence determines the limit of taxation, the highest tax rate that citizens will tolerate and pay. Rulers can spend resources on coercion to increase...

This research explores the historical roots of the division of labor in pre-modern societies. Exploiting a variety of identification strategies and a novel ethnic level dataset combining geocoded ethnographic, linguistic and genetic data, it shows that higher levels of intra-ethnic diversity...

The stability of many post-conflict societies rests on the successful reintegration of former soldiers. We examine social capital of former soldiers in Northern Uganda, where the Lord's Resistance Army forcibly recruited tens of thousands of youth during a recent brutal conflict. We use a set of...

The stability of many post-conflict societies rests on the successful reintegration of former soldiers. We use an experimental approach to study reintegration in Northern Uganda and examine behavior of former soldiers together with the behavior of receiving communities towards this group. We...
