The Sahel and the Sahara are faced with exceptional political instability involving a combination of rebellions, jihadist insurgencies, coups d’état, protest movements and illegal trafficking. The backdrop to this accumulated violence is a globalised security environment, which blurs the...

We survey selected parts of the growing literature on the microeconomics of violent conflict, identifying where academic research has started to establish stylized facts and where methodological and knowledge gaps remain. We focus our review on the role of civilian agency in conflict; on wartime...

A multi-stage model on the course of war is presented: Individual battles are modeled as private value all-pay auctions with asymmetric combatants of two opposing teams. These auctions are placed within a multi-stage framework with a tug-of-war structure. Such framing provides a microfounded...

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 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,...

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...

Does economic inequality diminish the capacity of democracies to extract voluntary sacrifice? And does inequality undermine citizen's willingness to do their civic duty when the state is under threat? We address these questions by linking income inequality with people's willingness to fight for...
