A voting scheme assigns to each profile of alternatives chosen by "n" individuals a compromise alternative. Here the set of alternatives is represented by the Euclidean plane. The individual utilities for the compromise point are equal to the negatives of the distances of this point to the...

This paper presents results from experiments with finitely repeated games with complete and incomplete information. We use two treatment variables: the number of rounds the game is played and the value of the probability that reflects the presence of incomplete information.

Equivalence classes of normal form games are defined using the geometry of correspondences of standard equilibiurm concepts like correlated, Nash, and robust equilibrium or risk dominance and rationalizability. Resulting equivalence classes are fully characterized and compared across different...

We introduce two ways of comparing information structures, say ${\cal I}$ and ${\cal J}$. First we say that ${\cal I}$ is richer than ${\cal J}$ when for every compact game $G$, all correlated equilibrium distributions of $G$ induced by ${\cal J}$ are also induced by ${\cal I}$. Second, we say...

We introduce notions of increasingness for the best reply of a game that capture properly the intuitive idea of complementarity among players’ strategies. We show, by generalizing the fixpoint theorems of Veinott and Zhou, that the Nash sets of our games with increasing best replies are...

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency in games with Pareto-ranked equilibria. We report an experiment in which two groups compete in a weakest-link contest by expending costly efforts. Allowing intra-group communication leads...

This paper develops a framework to explore firm corruption taking account of interaction with an auditor. The basic idea is that an auditor can provide auditing and other (consultancy) services. The extent of the other services depends on firm profitability. Hence auditor profitability can...

In an economy where entrepreneurs with unequal "abilities" face alternative investment projects, which differ in degree of risk and productivity, we analyse the Nash equilibrium contracts arising from a banks-borrowers game in the context of asymmetric information. We show that, for a particular...

We consider repeated games with transferable utility: players have an endowment of wealth in each period in which transfers can be made. We show that if endowments are large enough and the comon discount factor high enough, then a trongly renegotiation-proof equilibrium (SRP) in the sense of...
