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 self-governance is best for the population, it faces problems of long-term viability. Typically, in providing security...

We propose a framework with endogenous allocation of land between agricultural production, sustainable forest management, and unsustainable forest exploitation in the form of illegal logging to explore deforestation and agricultural and timber supplies when property rights are insecure....

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...

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...

We extend the model of insecure property rights by Tornell and Velasco (1992) and Tornell and Lane (1999) by adding three features: (i) extracting the common property asset involves a private appropriation cost, (ii) agents derive utility from wealth as well as from consumption, and (iii) agents...

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...

I consider a model in which an asset owner must decide how much to invest in his asset mindful of the fact that an encroacher’s valuation of the asset is increasing in the asset owner’s investment. Due to incomplete property rights, the encroacher and asset owner engage in a contest over 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...

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...

We examine how socio-political conflict in Bolivia has affected its economic performance since the 1970s. Such conflict includes strikes, demonstrations, road blockades, and conventional rent-seeking. Since conflict has costs, it diverts resources away from production, tends to reduce investment...
