چکیده
For (S, ) a measurable space, let C1 and C2 be convex, weak∗ closed sets of probability measures on . We show that if C1 ∪ C2 satisfies the Lyapunov property, then there exists a set A ∈ such that minμ1∈C1 μ1(A)>maxμ2∈C2 μ2(A). We give applications to Maxmin Expected Utility (MEU) and to the core of a lower probability.

We provide a simple behavioral definition of ‘subjective mixture’ of acts for a large class of (not necessarily expected-utility) preferences. Subjective mixtures enjoy the same algebraic properties as the ‘objective mixtures’ used to great advantage in the decision setting introduced by Anscombe and Aumann (1963). This makes it possible to formulate mixture-space axioms in a fully subjective s...

This paper analyzes a model of decision under ambiguity, deemed vector expected utility or VEU. According to the proposed model, an act f :Ω→X is evaluated via the functional V ( f ) = ∫

We develop a behavioral axiomatic characterization of subjective expected utility (SEU) under risk aversion. Given is an individual agent’s behavior in the market: assume a finite collection of asset purchases with corresponding prices. We show that such behavior satisfies a “revealed preference axiom” if and only if there exists a SEU model (a subjective probability over states and a concave u...
