We provide a methodology to study the role of market distortions on the emergence of indeterminacy and bifurcations. Most of the specific market imperfections considered in the related literature are particular cases of our framework. Comparing them we obtain several equivalence results in terms...

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...

Recently, many contributions have focused on the relationship between capital accumulation, growth and population dynamics, introducing fertility choice in macro-dynamic models. In this paper, we go one step further highlighting also the link with pollution. We develop a simple overlapping...

We re-examine the destabilizing role of balanced-budget fiscal policy rules based on consumption taxation. Using a one-sector model with infinitely-lived households, and assuming that preferences are of the Greenwood-Hercovitz-Huffman [8] (GHH) type, we show that non-linear consumption taxation...

We study the existence of equilibrium and rational bubbles in a Ramsey model with heterogeneous agents, borrowing constraints and endogenous labor. Applying a Kakutani's fixed-point theorem, we prove the existence of equilibrium in a time-truncated bounded economy. A common argument shows this...

We study the existence of equilibrium and rational bubbles in a Ramsey model with heterogeneous agents, borrowing constraints and endogenous labor. Applying a nonstandard fixed-point theorem by Gale and Mas-Colell's (1975), we prove the existence of equilibrium in a time-truncated bounded...

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...
