Lexicographic Expected Utility with a Subjective State Space∗
نویسندگان
چکیده
This paper provides a model that allows for a criterion of admissibility based on a subjective state space. For this purpose, we build a non-Archimedean model of preference with subjective states, generalizing Blume, Brandenburger, and Dekel [2], who present a non-Archimedean model with exogenous states; and Dekel, Lipman, and Rustichini [4], who present an Archimedean model with an endogenous state space. We interpret the representation as modeling an agent who has several “hypotheses” about her state space, and who views some as “infinitely less relevant” than others. JEL classification: D81

On the Representation of Beliefs by Probabilities
This paper explores two axiomatic structures of subjective expected utility assuming a ...nite state-space and state-dependent, connected, topological outcome-spaces. Building on the work of Karni and Schmeidler (1981) the analytical framework includes, in addition to the preference relation on acts, introspective preferences on hypothetical lotteries that are linked to the preference relation ...
متن کاملExpected Qualitative Utility Maximization
A model for decision making that generalizes Expected Utility Maximization is presented. This model, Expected Qualitative Utility Maximization, encompasses the Maximin criterion. It relaxes both the Independence and the Continuity postulates. Its main ingredient is the definition of a qualitative order on nonstandard models of the real numbers and the consideration of nonstandard utilities. Exp...
متن کاملSubjective Expected Utility Theory without States of the World
This paper develops an axiomatic theory of decision making under uncertainty that dispenses with the state space. The results are subjective expected utility models with unique, action-dependent, subjective probabilities, and a utility function defined over wealth-effect pairs that is unique up to positive linear transformation.

متن کاملSubjective expected utility theory with costly actions
This paper explores alternative axiomatizations of subjective expected utility theory for decision makers with direct preferences over actions; including a general subjective expected utility representation with actiondependent utility, and separately additive representations. In the context of the state-space formulation of agency theory the results of this paper constitute axiomatic foundatio...

We provide foundations for decisions in face of unlikely events by extending the standard framework of Savage to include preferences indexed by a family of events. We derive a subjective lexicographic expected utility representation which allows for infinitely many lexicographically ordered levels of events and for event-dependent attitudes toward risk. Our model thus provides foundations for m...
