Derivation of a cardinal utility through a weak trade-off consistency requirement

Research output: Contribution to journalArticlepeer-review


An axiomatic model is presented in which a utility function over consequences, unique up to location and unit, is derived. The assumptions apply to a binary relation over purely subjective acts, namely, no exogenous probabilities are assumed. The main assumption used is a weak trade-off consistency condition. The model generalizes the biseparable model of Ghirardato and Marinacci [Ghirardato P, Marinacci M (2001) Risk, ambiguity, and the separation of utility and beliefs.
