We consider rules (strategies, commitments, contracts, or computer programs) that make behavior contingent on an opponent's rule. The set of perfectly observable rules is not well defined. Previous contributions avoid this problem by restricting the rules deemed admissible. We instead limit the...

Das Papier befasst sich modelltheoretisch mit dem empirischen Phänomen des „Demokratischen Friedens“, der Beobachtung also, dass Demokratien ihre Konflikte in der Regel nicht kriegerisch lösen. Die Grundlage meiner Analyse bildet das Modell von Fearon (1995), ein Verhandlungsspiel mit 2...

The sealed-bid k-double auction mechanism for two-person bargaining under incomplete information can be extended by providing a bonus for both traders if, and only if, an agreement is reached. Brams and Kilgour (1996) proved that there is a unique level of bonus, namely, half the difference...

We consider the problem of a principal who wishes to contract with a privately informed agent and is not able to commit to not renegotiating any mechanism. That is, we allow the principal, after observing the outcome of a mechanism to renegotiate the resulting contract without cost by proposing...

It is well known that delegating the play of a game to an agent via incentive contracts may serve as a commitment device and hence provide a strategic advantage. Previous literature has shown that any Nash equilibrium outcome of an extensive-form principals-only game can be supported as a...

We propose a framework to analyze coalition formation with heterogeneous agents. Existing literature defines stability conditions that do not ensure that, once an agent decides to sign an agreement, the enlarged coalition is feasible. Defining the concepts of refraction and exchanging, we set up...

In this paper, we examine the optimal mechanism design of selling an indivisible object to one regular buyer and one publicly known buyer, where inter-buyer resale cannot be prohibited. The resale market is modeled as a stochastic ultimatum bargaining game between the two buyers. We fully...
