Nicolas Gravel et al., « Conditional expected utility criteria for decision making under ignorance or objective ambiguity », HAL-SHS : économie et finance, ID : 10.1016/j.jmateco.2018.08.001
We provide an axiomatic characterization of a family of criteria for ranking completely uncertain and/or ambiguous decisions. A completely uncertain decision is described by the set of all its consequences (assumed to be finite). An ambiguous decision is described as a set of possible probability distributions over a set of prizes. Every criterion in the family compares sets on the basis of their conditional expected utility , for some “likelihood” function taking strictly positive values and some utility function both having the universe of alternatives as their domain.
