We prove existence of stationary Markov perfect equilibria in an infinite-horizon model of legislative policy making in which the policy outcome in one period determines the status quo for the next. We allow for a multidimensional policy space and arbitrary smooth stage utilities, and we assume...

There is an ongoing discussion about the relationship of power and preferences: Is power reflected in what the agents can do and what they want to do, or, alternatively, are preferences and power two separate dimensions of determining the outcome of decisionmaking? In the latter case...

We characterize the efficiency properties of equilibrium, which is a departure from all the previous literature that focuses only on the probability of group success. While the probability of...

This paper studies the strategic role of extremism within a two-country multi-stage game and shows that, in general, an equilibrium exists in which extremism is used by both rivals. We show that often changes in the environment affect the two countries differently. Specifically, as a country...
