The conflict in Northern Ireland was an example of "complex warfare" with both insurgency and sectarian violence. We present a unified model that helps to identify these two forms of conflict from the spatial distribution of violence. The model predicts that tectonic boundaries between...

This chapter introduces the author's selected papers on the economics of coercion and conflict. It defines coercion and conflict and relates them. In conflict, adversaries make costly investments in the means of coercion. The application of coercion does not remove choice but limits it to...

We show that the recent rise in Afghan opium production is caused by violent conflicts. Violence destroys roads and irrigation, crucial to alternative crops, and weakens local incentives to rebuild infrastructure and enforce law and order. Exploiting a unique data set, we show that Western...

The relevance of political risk to international trade and investment remains a topic of continuing interest. However, summary measures of political risk, including country corruption, do not give consistent results. In this paper, we bring together two recent streams of literature to highlight...

Ethnic and religious fractionalization have important effects on economic growth and development, but their role in internal violent conflicts has been found to be negligible and statistically insignificant. These findings have been invoked in refutation of the Huntington hypothesis, according...

We study a model of war in which the outcome of the war is uncertain from the perspective of the involved countries not because of luck on the battlefield (as in standard models) but because of their lack of information about their opponents. In our model there are two countries characterized by...

We consider a situation where groups negotiate over the allocation of a surplus (which is used to fund group specific goods). Each group is composed of agents who have differing valuations for public goods. Members choose a representative to take decisions on their behalf. Specifically,...

Are natural resources a source of conflict or stability? Empirical studies demonstrate that rents from natural resources, and in particular oil, are an important source of civil war. Allegedly, resource rents attract rent seekers, which destabilize society. However, there is a large literature...

It has previously been shown that civil conflict influences many economic factors, including education, which play an important role in development and economic growth. Previous authors working on the influence of conflict on education have, however, always focused strongly on the supply-side...
