The goal of this report is to present the results from a unified conceptual framework so as to evaluate the cost-effectiveness and different trade-offs involved in conflict prevention. The context for the framework's development is a radical rethinking of the peacebuilding architecture put forth...

This paper studies long-term impacts of violent conflict, to provide insights into the costs of conflict and policies to prevent conflict relapse. The findings link evidence on the contemporaneous effects of conflict with its persistent impact, especially by combining multiple data sources such...

The article uses house prices to measure the peace dividend in Northern Ireland - and draws lessons for other parts of the world that have endured long conflicts.

We re-examine the labor donation theory of not-for-profits and show that these organizations may exist not necessarily because motivated workers prefer to work in them, or that they dominate for-profits in terms of welfare, but because the excess supply of motivated workers makes the non-profit...

We present a formal model of intra-party politics to explain candidate selection within parties. We think of parties as heterogeneous groups of individuals who aim to implement a set of policies but who differ in their priorities. When party heterogeneity is too large, parties are in danger of...

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 paper estimates the effect of piracy attacks on shipping costs using a unique data set on shipping contracts in the dry bulk market. We look at shipping routes whose shortest path exposes them to piracy attacks and find that the increase in attacks in 2008 lead to around a ten percent...

This article proposes a new measure of civil war. The measure defines violence intensity in casualties per capita instead of number of casualties. We discuss the assumptions behind this per capita model and the existing standard model. We show that the two measures behave differently in standard...
