Abstract Suppose a decision maker (DM) has partial information about certain events of a [sigma]-algebra belonging to a set and assesses their likelihood through a capacity v. When is this information probabilistic, i.e. compatible with a probability? We consider three notions of compatibility...

A main goal of this paper is to try to clarify the notions of impatience and myopia, often considered as synonymous in the literature. The occurrence of asset price bubbles (see Araujo et al., 2011) when only myopia is required, explains why we focused on a stronger notion that we define as...

We characterize preference relations over bounded below Anscombe and Aumann's acts and give necessary and sufficient conditions that guarantee the existence of a utility function u on consequences, a confidence function [phi] on the set of all probabilities over states of nature, and a positive...

We propose a model of decision making that captures reluctance to bet when the decision maker (DM) perceives that she lacks adequate information or expertise about the underlying contingencies. On the other hand, the same DM can prefer to bet in situations where she feels specially knowledgeable...
