In this chapter, we review the recent literature on conflict and appropriation. Allowing for the possibility of conflict, which amounts to recognizing the possibility that property rights are not perfectly and costlessly enforced, represents a significant departure from the traditional paradigm...

Civil wars and conflict can be understood from an economic point of view only if there is incomplete contracting. I examine such settings and first discuss sources of incomplete contracting, from geography and ethnic and social distance to external interventions due to geopolitics or the...

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...

Contest functions (alternatively, contest success functions) determine probabilities of winning and losing as a function of contestants’ eort. They are used widely in many areas of economics that employ contest games, from tournaments and rent-seeking to conflict and sports. We first examine...

In this paper, we explore two factors that can limit arming and, more generally, the costs of enforcement within and across states: governance or the formal organizations and institutions that help define and enforce property rights, and norms, or the informal arrangements in settling potential...

We construct a model of conflict and trade to study the consequences of interstate disputes over contested resources (land, oil, water or other resources) for arming, welfare and trade flows. Different trade regimes imply different costs of such disputes in terms of arming. Depending on world...

In this chapter, we examine how some of the main results in international trade theory fare when we abandon the traditional assumption of third-party enforcement of property rights. Without such enforcement, countries arm and exercise power to secure resources used in production or to secure the...

This chapter analyzes the influence of democratic institutions---specifically, the effects of (i) electoral uncertainty when individuals within a nation have different preferences over public peaceful investment and (ii) greater checks and balances that lead to a more effective mobilization of...

We explore the severity of an ongoing dispute over a productive resource within a country that participates in world trade. In addition to arming, the contending groups in our setting choose either to engage in destructive conflict or to settle their dispute peacefully. Our central objective is...

How do the outcomes of international wars affect domestic social change? In turn, how do changing patterns of social identification and domestic conflict affect a nation's military capability? Models that link structural variables, power politics, and the individuals that constitute states are...
