Abstract

Abstract Variational preferences (Maccheroni et al. in Econometrica 74:1447–1498, 2006) are an important class of ambiguity averse preferences, compatible with Ellsberg-type phenomena. In this paper, a new foundation for variational preferences is derived in a framework of two stages of purely subjective uncertainty. A similar foundation is obtained for purely subjective maxmin expected utility (Gilboa and Schmeidler in J Math Econ 18:141–153, 1989). By establishing their axiomatic foundations without the use of extraneous probabilities, the conceptual appeal and applicability of these ambiguity models is enhanced.
