Specific functional forms are often used in economic models of distributions; goodness-of-fit measures are used to assess whether a functional form is appropriate in the light of real-world data. Standard approaches use a distance criterion based on the EDF, an aggregation of differences in...

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...

An axiomatic approach is used to develop a one-parameter family of measures of divergence between distributions. These measures can be used to perform goodness-of-fit tests with good statistical properties. Asymptotic theory shows that the test statistics have well-defined limiting distributions...

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...

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 article addresses the important issue of anchoring in contingent valuation surveys that use the double-bounded elicitation format. Anchoring occurs when responses to the follow-up dichotomous choice valuation question are influenced by the bid presented in the initial dichotomous choice...
