We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle privately, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. Despite the additional costs of...

The Homo economicus of traditional economics is far from being completely self-interested, rational, or as individualistic as he is purported to be; he will haggle to death over price but will not take what he wants by force. Implicitly, he is assumed to behave ruthlessly within a welldefined...

We examine how the legal protection of outside shareholders and the appropriative costs that they induce influence the incentives for private firms to go public. A higher degree of protection of shareholders can increase the appropriative costs associated with the conflict between managers and...

We examine how globalization affects trade patterns and welfare when conflict prevails domestically. We do so in a simple model of trade, in which a natural resource like oil is contested by competing groups using real resources (?guns?). Thus, conflict is viewed as ultimately stemming from...

Leaders compensate supporters not just for performing their duties but also in order to preempt an overthrow by the same supporters. We show how succession rules affect the power of leaders relative to supporters as well as the resources expended on possible succession struggles. We compare two...

We examine a stark setting in which security or protection can be provided by self-governing groups or by for-profit entrepreneurs (kings, kleptocrats, or mafia dons). Though selfgovernance is best for the population, it faces problems of long-term viability. Typically, in providing security the...

We examine two factors that help explain the prevalence of conflict in low-income countries: that adversaries cannot enforce long-term contracts in arms, and that open conflict alters the future strategic positions of the adversaries differently than does peace. Using an infinite horizon model,...

From marketing and advertising to political campaigning and court proceedings, contending parties expend resources to persuade an audience of the correctness of their view. We examine how the probability of persuading the audience depends on the resources expended by the parties, so that...

In many instances of potential violent or non-violent conflict the future strategic positions of adversaries are very different when there is open conflict than when there is settlement. In such environments we show that, as the future becomes more important, open conflict becomes more likely...

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...
