In the first place, we present a quasi fixed-point theorem for a correspondence defined on some infinite-dimensional locally convex topological vector space such that some variables have open lower sections and the other ones are upper semicontinuous. In the second place, we propose a direct...

We investigate the stability problem for a nonlinear autoregressive model with Markov switching. First we give conditions for the existence and the uniqueness of a stationary ergodic solution. The existence of moments of such a solution is then examined and we establish a strong law numbers for...

We extend the Mirrlees model of optimal income taxation to include the optimal provision of public goods and we analyze the problem of budget balancedness.

Une methodologie alternative aux modeles multicriteres fondes sur l'etude economique et financiere de la firme est proposee afin d'estimer le risque de defaut des entreprises et d'elaborer un indicateur du risque de faillite. Nous recourons a une methode de Gestion Actif - Passif d'estimation...

En traitement automatique de la langue naturelle, l'analyse lexicale d'un texte est faite a partir de dictionnaires electroniques. Ceux-ci comportent tres peu de Noms Propres. Un travail de collecte des toponymes (noms de lieux) et gentiles (noms d'habitants) pour la France a ete mene. 55508...

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...
