Imprecise probabilistic beliefs as a context for decision-making under ambiguity

Abstract: Coherent imprecise probabilistic beliefs are modeled as incomplete comparative likelihood relations admitting a multiple-prior representation. Under a structural assumption of Equidivisibility, we provide an axiomatization of such relations and show uniqueness of the representation. In the second part of the paper, we formulate a behaviorally general "Likelihood Compatibility" axiom relating preferences and probabilistic beliefs and characterize its implications for the class of "invariant biseparable" preferences that includes the MEU and CEU models among others.
