in the Choquet Uncertainty model, letting u and μ (v and ν) be Ursula's (Victor's) utility and capacity. A necessary and … sufficient condition (A) on the pairs (u, μ) and (v, ν) will be presented for dichotomous weak increased uncertainty aversion … indifferent. Condition A is thus a characterization of weak increased uncertainty aversion for convex f. An example will be …

We develop an axiomatic approach to decision under uncertainty that explicitly takes into account the information …

We provide a general theorem on the aggregation of preferences under uncertainty. We study, in the Anscombe …-Aumann setting a wide class of preferences, that includes most known models of decision under uncertainty (and state …". The latter means that society cannot have a non-neutral attitude towards uncertainty on a subclass of acts. A corollary to …

that includes most known models of decision under uncertainty as well as state dependent versions of these models. We prove … that aggregation is possible and necessarily linear if and only if (society's) preferences are uncertainty neutral. The … latter means that society cannot have a non-neutral attitude toward uncertainty on a subclass of acts. A corollary to our …

general result is that a small number of reasonable assumptions regarding welfare orderings under uncertainty rule out pure ex …
