This paper shows that, for CEU preferences, the axioms consquentialism, state independenceand conditional certainty equivalent consistency under updating characterise a family of capacities,called Genralised Neo-Additive Capacities (GNAC). This family contains as special casesamong others...

In [7] Ghirardato, Macheroni and Marinacci (GMM) propose a method for distinguishing between perceived ambiguity and the decision-maker's reaction to it. They study a general class of preferences which they refer to as invariant biseparable. This class includes CEU and MEU. They axiomatize a...

In this paper, we consider a decision-maker who tries to learn the distribution ofoutcomes from previously observed cases. For each observed sequence of casesthe decision-maker predicts a set of priors expressing his beliefs about the underlyingprobability distribution. We impose a version of...
