چکیده

We propose two related equilibrium re…nements for voting and agenda-setting games, Sequentially Weakly Undominated Equilibrium (SWUE) and Markov Trembling Hand Perfect Equilibrium (MTHPE), and show how these equilibrium concepts eliminate non-intuitive equilibria that arise naturally in dynamic voting games and games in which random or deterministic sequences of agenda-setters make o¤ers to several players. We establish existence of these equilibria in …nite and in…nite (for MTHPE) games, provide a characterization of the structure of equilibria, and clarify the relationship between the two concepts. Finally, we show how these concepts can be applied in a dynamic model of endogenous club formation. Keywords: voting, agenda-setting games, Markov trembling-hand perfect equilibrium. JEL Classi…cation: D72, C73. Daron Acemoglu gratefully acknowledges …nancial support from the National Science Foundation.

Robust Political Equilibria under Plurality and Runoff Rule∗

A central problem for the game theoretic analysis of voting is that voting games have very many Nash equilibria. In this paper, we consider a new refinement concept for voting games that combines two ideas that appear reasonable for voting games: First, trembling hand perfection (voters sometimes make mistakes when casting their vote) and second, coordination of voters with similar interests. W...

Empirical analysis of plurality election equilibria

Voting is widely used to aggregate the different preferences of agents, even though these agents are often able to manipulate the outcome through strategic voting. Most research on manipulation of voting methods studies (1) limited solution concepts, (2) limited preferences, or (3) scenarios with a few manipulators that have a common goal. In contrast, we study voting in plurality elections thr...
