This paper reviews the economics approach to conflict and national borders. The paper (a) provides a summary of ideas and concepts from the economics literature on the size of nations; (b) illustrates them within a simple analytical framework where populations fight over borders and resources,...

We investigate situations in which players make costly contributions as group members in a group conflict, and at the same time engage in contest with fellow group members to appropriate the possible reward. We introduce within group power asymmetry and complementarity in members’ efforts, and...

I critically review recent studies that estimate those costs of violence and conflict that can emerge among organized political groupings, from states, religious and ethnic organizations to guerillas and paramilitaries. The review includes studies that estimate direct and indirect costs due to...

We assess the robustness of previous findings on the determinants of terrorism. Using extreme bound analysis, the three most comprehensive terrorism datasets, and focusing on the three most commonly analyzed aspects of terrorist activity, i.e., location, victim, and perpetrator, we re-assess the...

Wars of conquest and wars of independence are characterized by an asymmetric payoff structure: one party gets aggregate production if it wins, and its own production if it loses, while the other party gets only its own production if it wins, and nothing if it loses. We study a model of war with...

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...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...

This paper examines conflicts in which performance is measured by the players' success or failure in multiple component conflicts, commonly termed “battlefields”. In multi-battlefield conflicts, behavioral linkages across battlefields depend both on the technologies of conflict within each...

Many experts claim that the incidence of suicide attacks is driven by religious cleavages. To test this hypothesis, we investigate whether the total number of suicide attacks per violent conflict or the annual number of suicide attacks per country is associated with simmering religious...

A demographic transition resulting from an increase in the size of the young working age population can be a blessing or a curse for economic performance. We focus on the political stability effects of a larger youth population and hypothesize that corruption matters in this nexus. Using panel...
