Decision Making and Imprecise Beliefs

March 17, 2017, HEC Paris (Porte de Champerret Site), Paris.

Beliefimg_7251s, of course, play a central role in decision making under uncertainty. There has been increasing attention on the issues thrown up by imprecision in beliefs or preferences, both in the economic and psychological literature. What effects does the lack of precise probabilistic beliefs, or different sorts of uncertainty have on preferences? How does imprecision translate into choice? How does imprecision affect belief formation? How can it be elicited?

The objective of this workshop, the fifth in a series, is to bring together researchers working on such topics, in both theoretical and experimental perspectives, and to foster discussion and exchange.

Participation to the workshop is free, but registration is compulsory. We therefore kindly ask would-be participants to register as soon as possible, by sending an email to Mrs. Nathalie Beauchamp (, indicating your name and affiliation.
