"Choquet expected utility across time without lotteries"
Co-écrit avec José Heleno Faro (Insper)
Abstract :
In this paper we axiomatise an inter-temporal version of the Choquet Expected Utility model by recasting Koopmans Discounted Utility model in a framework with uncertainty. A new axiom, called comonotonic stationarity, is proposed as a generalization of Koopmans stationarity axiom. Under other standard axioms used in the theory of inter-temporal choice, a decision maker will evaluate a stream of income through the Choquet integral of discounted utilities. As a dividend, our setting allows to axiomatize the Discounted Expected Utility model.
