We present a preference foundation for Chance Theory (CT), a model of decision making under uncertainty where the … and the potential increments over it are evaluated by subjective expected utility with a risky utility function u. In … contrast to earlier approaches with models that aimed at separating riskless and risky utility, CT does not violate basic …

model generalizes many well known utility functions for intertemporal decision making under risk. A decision maker with a … weighted temporal utility function can have time consistent yet non-stationary preferences or stationary yet time inconsistent …We propose a novel utility representation for preferences over risky timed outcomes. The weighted temporal utility …

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...

In this paper we show that decision makers who maximize expected utility on a two-dimensional set of the real numbers … (i.e., who maximize expected utility on R×R) rather than on the real numbers alone, can act in ways predicted by the … Allais in his original 1953 paper can be explained by the extended expected utility model that is described in this paper …
