Maximal-Element Rationalizability∗
We examine the maximal-element rationalizability of choice functions with arbitrary domains. While rationality formulated in terms of the choice of greatest elements according to a rationalizing relation has been analyzed relatively thoroughly in the earlier literature, this is not the case for maximal-element rationalizability, except when it coincides with greatest-element rationalizability b...
متن کاملComprehensive Rationalizability∗
We present a new solution concept for strategic games called comprehensive rationalizability that embodies a new version of “common cautious belief in rationality” based on a sound epistemic characterization in a universal type space. Differently from existing iterative strategy elimination procedures in the literature, it should rather be viewed as an iterative strategy demotion procedure as i...
متن کاملCoalitional Rationalizability
This paper investigates how groups or coalitions of players can act in their collective interest in non-cooperative normal form games even if equilibrium play is not assumed. The main idea is that each member of a coalition will confine play to a subset of their strategies if it is in their mutual interest to do so. An iterative procedure of restrictions is used to define a non-cooperative solu...
متن کاملSocial Rationalizability
Social environments constitute a framework in which it is possible to study how groups of agents interact in a society. The framework is general enough to analyse both noncooperative and cooperative games. We identify a number of shortcomings of existing solution concepts that are used for social environments and propose a new concept called social rationalizability. The concept aims to identif...
متن کاملInterim correlated rationalizability
This paper proposes the solution concept of interim correlated rationalizability, and shows that all types that have the same hierarchies of beliefs have the same set of interim-correlated-rationalizable outcomes. This solution concept characterizes common certainty of rationality in the universal type space.
