In this paper, 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 of...

The generic alliance game considers players in an alliance who fight against an external enemy. After victory, the alliance may break up, and its members fight against each other about the spoils of the victory. Our experimental analysis of this game shows: In-group solidarity vanishes after the...

This paper presents a new model of interest groups and policy formation in the legislature. In our setting, the already given party ideological predispositions and power distribution determine the expected policy outcome. Our analysis applies to the case of un-enforced or enforced party...

This paper formulates a simple mathematical framework for the selection of an optimum "relative unanimity” collective decision rule. The approach is first to identify the benefits of moving from a rule of simple majority towards a rule of full unanimity. Then, the costs of moving from simple...

We extend the model of collective action in which groups compete for a budged by endogenizing the group platform, namely the specific mixture of public/private good and the distribution of the private good to group members which can be uniform or performance-based. While the group-optimal...

This paper evaluates differential prize taxation and structural discrimination as a means of increasing efforts in the most widely studied contests. We establish that a designer who maximizes efforts subject to a balanced-budget constraint prefers dual discrimination, namely, change of the...

This paper evaluates direct and structural discrimination as a means of increasing efforts in the most widely studied contests. We establish that a designer who maximizes efforts subject to a balanced-budget constraint prefers dual discrimination, namely, change of the contestants’ prize...

This paper considers a partial equilibrium model of conflict where two asymmetric, rational and risk-neutral opponents clash in order to redistribute a divisible prize in their favour. Differently from common contest models agents have the option of choosing a second instrument to affect the...

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...
