We show that groups are more likely to make ambiguity-neutral decisions than individuals, and that individuals make … more ambiguity-neutral decisions after discussing the decisions with others. This shift toward higher ambiguity neutrality …

We provide a model of decision making under uncertainty in which the decision maker reacts to imprecision of the … notions of comparative aversion to imprecision of the data as well as traditional notions of risk aversion. Interestingly, the … study of comparative aversion to imprecision can be done independently of the utility function, which embeds risk attitudes …
