Eichberger, Jürgen; Grant, Simon; Lefort, Jean-Philippe Generalized neo-additive capacities and updating. (English) Zbl 1416.91080 Int. J. Econ. Theory 8, No. 3, 237-257 (2012). Summary: This paper shows that, for Choquet expected utility preferences, the axioms consquentialism, state independence and conditional certainty equivalent consistency under updating characterise a family of capacities, which we call generalized neo-additive capacities (GNAC). This family contains as special cases, among others, neo-additive capacities as introduced by Chateauneuf, Eichberger, and Grant, Hurwicz capacities, and \(\varepsilon\)-contaminations. Moreover, we will show that the convex version of a GNAC is the only capacity for which the core of the full Bayesian updates of a capacity, introduced by Jaffray, equals the set of Bayesian updates of the probability distributions in the core of the original capacity.
