ambiguity averse relation. First, we define two notions of more ambiguous with respect to such a class. A more ambiguous (I) act … makes an ambiguity averse decision maker (DM) worse off but does not affect the welfare of an ambiguity neutral DM. A more … ambiguous (II) act adversely affects a more ambiguity averse DM more, as measured by the compensation they require to switch …

For choice with deterministic consequences, the standard rationality hypothesis is ordinality, i.e., maximization of a weak preference ordering. For choice under risk (resp. uncertainty), preferences are assumed to be represented by the objectively (resp. subjectively) expected value of a von...

Under state-dependent preferences, probabilities and units of scale of state-dependent utilities are not separately identified. In standard models, only their products matter to decisions. Separate identification has been studied under implicit actions by Drèze or under explicit actions and...

Anscombe and Aumann (1963) offer a definition of subjective probability in terms of comparisons with objective probabilities. That definition - which has provided the basis for much of the succeeding work on subjective probability - presumes that the subjective probability of an event is...

Under the assumption that … an ambiguity averse subject should reduce ambiguity within a decision process we predicted that these subjects would … request more information.
