We extend the notions of evolutionary stability and, for the first time, that of neutral stability to asymmetric games played between two populations. Stability with respect to simultaneous entry of a small proportion of mutants into both populations is considered. Allocations where neither...

The results of an experiment are reported where subjects played within a repeated random matching environment a simple game in extensive form. In this game backward induction based on the focal-point outcome in subgame yields an outcome different from the one that would be deduced using forward...

We call a set of strategies "uniformly evolutionary stable" if the following holds after a small mutation of a monomorphic population playing a strategy in the set: a) No mutant strategy can spread. b) Mutant strategies not in the set will be driven out. c) The meaning of a "small mutation" can...

In a sequential bargaining model of coalition formation and payoff M division players form demands for their participation in a coalition. These M demands have some appealing, intuitive features. We characterize the sets of M semi-stable and stable demands vectors for general NTU games using M...

In this paper we analyze a simple non-cooperative bargaining model for coalition formation and payoff distribution for games in coalitional form. We show that under our bargaining regime a cooperative game is core-implementable and if it possesses the property of increasing returns to scale for...

This paper considers characterizations of perfect recall in extensive form games. It is shown that perfect recall can be expressed entirely in terms of the choice partition without any reference to any information sets. When information sets are taken into account it is decomposable into an...
