Humanitarian inviolability - the ability of humanitarian agencies to be able to carry out their activities free from attack - depends upon the understanding that humanitarian agencies are neutral and impartial, but the very concept has been thrown into crisis, most spectacularly by the bombing...

We augment the canonical neoclassical model of trade to allow for interstate disputes over land, oil, water, or other resources. The costs of such disputes in terms of arming depend on the trade regime in place. Under either autarky or free trade, the larger country (in terms of factor...

In this paper we extend the well known "agreeing-to-disagree" and "no-trade" results from economics and game theory to international relations. We show that two rational countries should never agree to go to war when war is inefficient and when rationality is common knowledge. We argue that this...

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...

Typically, economics assumes that property rights over productive resources or goods are perfectly defined and costlessly enforced. The costs of insecurity and the resultant conflict are, however, real and often economically significant. In this paper, we examine how international trade regimes...

We consider a dynamic setting in which two sovereign states with overlapping ownership claims on a resource/asset first arm and then choose whether to resolve their dispute violently through war or peacefully through settlement. Both approaches depend on the states' military capacities, but...

This paper investigates whether distributional conflicts become more likely when groups are involved in the fight. We present results from a laboratory experiment in which two parties can appropriate resources via a contest or, alternatively, take an outside option. Keeping monetary gains...

Enduring violent conflict is the flip side of the coin of a weak state. In this article, I propose some political economy underpinnings for the persistence of conflict (and the weak state). Focusing on the case of Colombia, I discuss three broad sets of mechanisms that are also relevant...
