This paper develops a coherent theory of international cooperation relying on the twin assumptions of individual and collective rationality. Using a linear version of the N-player prisoner's dilemma game, I provide a formal proof of Olson's conjecture that only a `small' number of countries can...

We provide a theory that derives conditions under which presidents' ability to increase the salience of an issue will generate legislative influence and correspondingly, conditions under which presidents will engage in this activity of public agenda setting. The theory shows that presidents can...

In this paper we argue that spatial voting games and power index models are not necessarily exclusive ways to analyse EU decision-making. We find that the two main criticisms pointed out by scholars of spatial voting games, namely that power indices do not take into account preferences or the...

Riker's `size principle' predicts that only minimal winning coalitions (MWCs) will form in n-person zero-sum games that satisfy certain conditions. After summarizing the logic of this principle, a model is proposed in which n players can be ordered from most to least weighty. Two different kinds...

I address the role of social mobility in political transitions. I develop a political economy model of regime transitions that incorporates social mobility as a key feature of the economy capturing the political attitudes toward redistribution. I show that social mobility facilitates...

In this paper we focus on the way in which courts affect public policy. We present a model of judicial behavior that combines insights from theories emphasizing the importance of policy preferences with those suggesting that courts are only motivated by formal-legal criteria. By embedding our...
