Atemporal non-expected utility preferences, dynamic consistency and consequentialism
Résumé
This note studies conditions which allow to maintain a non-expected utility representation (Max-min expected utility and Choquet expected utility), dynamic consistency and consequentialism in an atemporal and purely subjective framework. By contrast with a dynamic set-up, where consistency can be reached with non-expected utility models, we show that both Maxmin expected utility and Choquet expected utility degenerate into an expected utility representation.
