Analysis of our new, 16-year dataset on the Colombian civil war finds under Uribe: guerrilla and paramilitary attacks dropping sharply against long-run averages since 1988, lower for April-December, 2003; government-guerrilla clashes at all-time highs, exceeding guerrilla attacks; civilian killings...

We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other...

This paper studies empirically the impact of mining on conflicts in Africa. Using novel data, we combine geo-referenced information over the 1997-2010 period on the location and characteristics of violent events and mining extraction of 27 minerals. Working with a grid covering all African...

This paper studies the incidence of civil war over time. We put forward a canonical model of civil war, which relates the incidence of conflict to circumstances, institutions and features of the underlying economy and polity. We use this model to derive testable predictions and to interpret the...

We use new data to examine the effects of giant oilfield discoveries around the world since 1946. On average, these discoveries increase per capita oil production and oil exports by up to 50 percent. But these giant oilfield discoveries also have a dark side: they increase the incidence of...

We propose a market-for-offenses model of property crime, which explicitly accounts for protection expenditures among heterogeneous individuals. The crime equilibrium is modeled as a free-access equilibrium in which the match between criminals and victims equates the average returns to crime. We...

This paper investigates the effects of ethnic violence on export-oriented firms and their workers. Following the disputed 2007 Kenyan presidential election, export volumes of flower firms affected by the ensuing violence dropped by 38 percent and worker absence exceeded 50 percent. Large firms...

This paper uses detailed information on the latitude and longitude of conflict events in Sub-Saharan African countries to study the impact of external income shocks on the likelihood of violence. We consider a number of external demand shocks faced by the countries or the regions within...
