  1. Dynamic Decision Making When Risk Perception Depends on Past Experience.Michèle Cohen, Johanna Etner & Meglena Jeleva - 2008 - Theory and Decision 64 (2-3):173-192.
    The aim of the paper is to propose a preferences representation model under risk where risk perception can be past experience dependent. A first step consists in considering a one period decision problem where individual preferences are no more defined only on decisions but on pairs (decision, past experience). The obtained criterion is used in the construction of a dynamic choice model under risk. The paper ends with an illustrative example concerning insurance demand. It appears that our model allows to (...)

    How to Deal with Partially Analyzable Acts?Jean-Yves Jaffray & Meglena Jeleva - 2011 - Theory and Decision 71 (1):129-149.
    In some situations, a decision is best represented by an incompletely analyzed act: conditionally on a given event A, the consequences of the decision on sub-events are perfectly known and uncertainty becomes probabilizable, whereas the plausibility of this event itself remains vague and the decision outcome on the complementary event ${\bar{A}}$ is imprecisely known. In this framework, we study an axiomatic decision model and prove a representation theorem. Resulting decision criteria aggregate partial evaluations consisting of (i) the conditional expected utility (...)
