  1. An Experimental Investigation of Imprecision Attitude and its Relation with Risk Attitude and Impatience.Michèle Cohen, Jean-Marc Tallon & Jean-Christophe Vergnaud - 2011 - Theory and Decision 71 (1):81-110.
    We report in this paper the result of three experiments on risk, ambiguity and time attitude. The first two differed by the population considered (students vs. general population) while the third one used a different protocol and concerned students and portfolio managers. We find quite a lot of heterogeneity at the individual level. Of principal interest was the elicitation of risk, time and ambiguity attitudes and the relationship among these (model free) measures. We find that on the student population, there (...)

  2. 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 (...)
