Journal ArticleDOI
An axiomatic characterization of preferences under uncertainty: Weakening the independence axiom
TL;DR: In this article, the independence axiom used to derive the expected utility representation of preferences over lotteries is replaced by requiring only convexity, in terms of probability mixtures, of indifference sets.
Journal ArticleDOI
Hierarchies of Beliefs and Common Knowledge
Adam Brandenburger,Eddie Dekel +1 more
TL;DR: In this paper, Mertens and Zamir showed that if a player's type is coherent then it induces a belief over the types of the other players, and that the notion of coherency closes the model of beliefs.
Journal ArticleDOI
Rationalizability and correlated equilibria
Adam Brandenburger,Eddie Dekel +1 more
TL;DR: In this paper, it is shown that correlated rationalizability is equivalent to a posteriori equilibrium, a refinement of subjective correlated equilibrium, and a decision-theoretic justification for the equilibrium approach to game theory is provided.
Journal ArticleDOI
Representing preferences with a unique subjective state space
TL;DR: In this article, the authors extend Kreps' 1979 analysis of preference for flexibility, reinterpreted by Kreps Ž.1992 as a model of unforeseen contingencies, and obtain uniqueness results that were not possible in Kreps’ model.
Journal ArticleDOI
Lexicographic probabilities and choice under uncertainty
TL;DR: In this paper, a non-Archimedean variant of subjective expected utility where decisionmakers have lexicographic beliefs is developed, which can be made to satisfy admissibility and yield well-defined conditional probabilities and at the same time allow for "null" events.
