There exist three equivalent definitions of perfect Nash equilibria which differ in the way "best responses against small perturbations" are defined. It is shown that applying the spirit of these definitions to rationalizability leads to three different refinements of rationalizable strategies...

A consistent pair specifies a set of "rational" strategies for both players such that a strategy is rational if and only if it is a best reply to a Bayesian belief that gives positive probability to every rational strategy of the opponent and probability zero otherwise. Although the idea...

I study the evolution of rationality, using an indirect evolutionary approach, in which nature selects a decision …-making procedure, and the procedure chooses actions in matching-games. The main result is that in order for (knowledge of) rationality …

In this study we propose a formal framework for the indirect evolutionary approach initiated by Guth and Yaari. It allows us to endogenize preferences and to study their evolution. We define two-player indirect evolutionary games with observable types and show how to incorporate symmetric as...
