Les scénarios pour le développement énergétique à long terme et les émissions de gaz à effet de serre associées ont acquis un rôle particulier par rapport aux autres familles de scénarios. Dans le cas de l'énergie et du climat il s'agit de fournir une information essentielle pour la...

L'objectif principal du projet était d'étendre le cadre Bayésien, modèle standard en économie pour la formalisation de l'incertitude, des croyances, de l'apprentissage, de l'information...; modèle qui conduit à des prédictions fortes et parfois peu réalistes en économie théorique. Or...

The Action Lecture program is an innovative teaching method run in some nursery and primary schools in Paris and designed to improve pupils' literacy. We report the results of an evaluation of this program. We describe the experimental protocol that was built to estimate the program's impact on...

One main topic of the epistemic program of game theory deals with the value of information. To study this question in a broad context, one needs to adapt some of the tools used in multiplayer epistemic logic. A hierarchical belief structure is introduced both in a syntactical and semantical...

Cet article développe un modèle théorique d'économie urbaine qui étudie les conséquences d'effets de voisinage informationnels sur l'organisation de la ville. Il s'agit, en particulier, d'examiner l'impact de tels effets de voisinage sur le processus de ségrégation urbaine. Pour ce...

The purpose of this chapter is thus to review the concept of peak oil, critique its main propositions and assess the arguments advanced by oil optimists against those of peak oil. The paper begins with a presentation of the Hubbert peak theory and of some recent applications of the theory at the...

In this chapter, we adopt the decision theoretic approach to the representation and updating of beliefs. We take up this issue and propose a reconsideration of Hammond's argument. After reviewing the argument more formally, we propose a weaker notion of dynamic consistency. We observe that this...

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...

This paper presents an axiomatic model of decision making under uncertainty which incorporates objective but imprecise information. Information is assumed to take the form of a probability-possibility set, that is, a set $P$ of probability measures on the state space. The decision maker is told...

This paper presents an axiomatic model of decision making which incorporates objective but imprecise information. We axiomatize a decision criterion of the multiple priors (or maxmin expected utility) type. The model achieves two primary objectives. First, it explains how subjective belief...
