The Political Economy of Dynamic Elections: Accountability, Commitment, and Responsiveness” (2017) with Cesar Martinelli. This paper contains a survey and synthesis of the literature on electoral accountability, i.e., repeated elections in which politicians cannot commit their policy choices. We establish sets of conditions under which policy choices nevertheless reflect the preferences of the median voter. Here is a longer version that contains proofs omitted from the shorter paper. Journal of Economic Literature, forthcoming.

Term Limits and Bounds on Policy Responsiveness in Dynamic Elections (2016) I examine the possibility of policy responsiveness in an infinite-horizon model of elections with a two-period term limit, under the assumption of adverse selection and moral hazard. I characterize equilibria and prove existence of equilibrium, pointing out and correcting an error in the proof of Banks and Sundaram (1998). The current version contains corrections of many errors in the previous version. Here are some slides from a talk. Journal of Economic Theory, forthcoming.

Dynamic Bargaining and External Stability with Veto Players (2016) with Vincent Anesi. We establish ergodic properties of equilibria in the finite environment of Anesi (2012), and we show that when players are patient and the voting rule is oligarchical, a set is a von Neumann-Morgenstern solution if and only if it consists of the absorbing points of an equilibrium. We also establish this result in the model with general voting rule and a persistent agenda setter. Games and Economic Behavior, forthcoming.

Existence of Stationary Bargaining Equilibria” (2017) An existence theorem for stationary equilibria in a general class of bargaining models assuming only continuity and compactness conditions -- no convexity or comprehensiveness assumptions are used. This is a revision of the paper formerly known as “Coalitional Bargaining Equilibria”. Here are some slides from a shorter talk that was pretty good. Here are some slides from a longer talk that was probably less clear. Games and Economic Behavior, 102: 111--126.

May’s Theorem in One Dimension (2017) I provide characterizations of majority rule using the axioms of Kenneth May, but assuming single-peaked preferences and substituting transitivity properties for the more controversial positive responsiveness axiom. Journal of Theoretical Politics, 29: 3--21.

"Limits of Acyclic Voting" (2015) An Arrovian result for acyclic social choice under the independence of irrelevant alternatives. This is an abbreviated version of “Limits of Acyclic Voting and Nash Implementation” (below) less the implementation result, plus results for saturated domains, large numbers of alternatives, and a version of acyclicity that precludes cycles of an arbitrary, fixed length. This is an abbreviated version of “Limits of Acyclic Voting and Nash Implementation,” less the implementation result, plus results for saturated domains and large numbers of alternatives. Journal of Economic Theory, 163: 658--683.

Purification of Bayes Nash Equilibrium with Correlated Types and Interdependent Payoffs (2015) with Paulo Barelli. Here are some slides from a talk. Games and Economic Behavior, 94: 1--14.

Preference Exclusions for Social Rationality(2015) I provide conditions for transitive and acyclic voting under general preference restrictions, and I extend known results for value restriction, single peakedness, weak single peakedness, and order restriction. For median voter theorems and representative voter theorems, see my unpublished paper, “Value Restriction, Median Voters, and the Core.” Social Choice and Welfare, 46: 93--118.
