We present the model of games with incomplete information first introduced by Harsanyi and show the link with extensive form games with imperfect information. We provide then a construction of the universal type space of Mertens and Zamir together with some properties.

For a given finite poset (P,-<), we construct strict completions of P which are models of all finite lattices L such that the set of join-irreducible elements of L is isomorphic to P.

Nous nous inscrivons dans le cadre theorique d'un modele d'equilibre general intertemporel stochastique purement reel a deux pays pour analyser la dynamique des taux de chomage nationaux suite a l'occurrence de chocs asymetriques. Il s'agit en cela d'un modele non-walrasien dans lequel le...

Cet article se propose d'evaluer l'existence des enigmes de la prime de risque et du taux sans risque sur donnees francaises de 1897 a 1996. Nous verifions tout d'abord l'inaptitude du modele standard d'evaluation d'actifs base sur la consommation a reproduire la prime de risque historique pour...

We present a model that focuses on the links between location and educational choices in South African cities. Be comparing the Apartheid city and the post-Apartheid city, we show that the inequality in South Africa between blacks and whites decreases when Apartheid laws are removed.

The model developed in this paper extends the strategic location framework under Cournot competition in order to allow for different production costs across locations.

In a vertical differentiation model, we investigate whether the property of finiteness holds when the average cost function depends on the quantity. We prove that this property holds when the cost function has increasing returns. In the case of cost functions with decreasing returns, we prove...

Notre objectif est de construire une maquette simple de l'economie francaise, susceptible d'etre utilisee pour des travaux de prevision et d'evaluation des politiques macroeconomiques.
