De récents événements ont remis sur le devant de la scène la dangerosité potentielle du virus de la grippe (épidémie de Hong-Kong 1997...). Le vaccin, généralement jugé efficace, reste pourtant sous-utilisé par rapport aux avantages qu'il procure. Pendant plusieurs décennies, les...

This paper shows that, for CEU preferences, the axioms consquentialism, state independence and conditional certainty equivalent consistency under updating characterise a family of capacities, called Genralised Neo-Additive Capacities (GNAC). This family contains as special cases among others...

This paper explores the relationship between dynamic consistency and existing notions of unambiguous events for Choquet expected utility preferences. A decision maker is faced with an information structure represented by a filtration. We show that the decision maker’s preferences respect...

In this paper, we extend Aumann’s (Ann Stat 4:1236–1239, 1976) probabilistic agreement theorem to situations in which agents’ prior beliefs are represented by a common neo-additive capacity. In particular, we characterize the family of updating rules for neo-additive capacities, which are...
