This paper develops a dynamic model of legislative policy making with evolving, privately observed policy preferences. Our goal is to find conditions under which decision rules, which assign feasible policies based on the legislators' preferences, are sustainable in the long run. We show that...

We present a theory of dynamic coalitions for a legislative bargaining game in which policies can be changed in every period but continue in effect in the absence of new legislation. We characterize Markov perfect equilibria with dynamic coalitions, which are decisive sets of legislators whose...

We study repeated legislative bargaining in an assembly that chooses its bargaining rules endogenously, and whose members face an election after each legislative term. An agenda protocol or bargaining rule assigns to each legislator a probability of being recognized to make a policy proposal in...

We study dynamic committee bargaining over an infinite horizon with discounting. In each period a committee proposal is generated by a random recognition rule, the committee chooses between the proposal and a status quo by majority rule, and the voting outcome in period t becomes the status quo...

Why do contests exist in settings where negotiation provides a costless alternative? I assess a new explanation: parties may be overconfident about their ability or optimistic about their chances of winning. For both parties in a contest, this hubris: (i) reduces the incentive to exit the...

Two players with independent private values compete for a prize in an all-pay contest. Before the contest, each player can spy on the opponent by privately acquiring a costly, noisy, and private signal about his private value. In a symmetric equilibrium of the contest where players spy on each...
