IN this paper firstly, we obtain convergence results for a sequence of minimal elements of sets under assumptions of minimal character. Then, we present similar results for suitable notions of approximate minimal elements of sets.

On etudie l'interdependance des economies dans un modele a horizon infini et compose de deux pays. Trois elements distinguent les pays : la productivite globale des facteurs, les dotations initiales et l'elasticite de substitution intertemporelle des consommateurs sont differents dans les deux...

L'origine de ce travaial reside dans la question, dite teleologique, de la justification de scenarios determines par optimisation intertemporelle, pour les modeles macroeconomiques d'une economie non planifiee, mais susceptible de regulation. On aborde cette question par un approche constructive...

This paper investigates necessary conditions for an equilibrium to exist on a reinsurance market with short sale constraints. It establishes that, equilibrium, there exists an equivalent probability measure under which the reinsurance premium is the compensator of the jump process describing the...

The aim of this paper is to reveal empirically two kinds of mechanismis which operate on inventories: one is demand related and the other is supply related.

We consider repeated games of complete information and imperfect monitoring, where the observation structure is given by a directed graph, i.e. all what a player learns are the actions taken by his neighbours on the graph. We prove that a generalized folk theorem holds if and only if the graph...

Kimball [1990] developps a theory of prudence isomorphic to Pratt [1964] and Arrow [1965] theory of risk aversion. Nevertheless, if the Arrow-Pratt risk aversion index determines behavior in risk, it is not always the case for prudence. Moreover, concept of prudence and precautionary behavior...

Dans cet article, nous examinons dans quelle mesure l'integration verticale, qu'elle se traduise par la forclusion des concurrents aval ou par la participation au marche intermediaire, emerge comme strategie d'equilibre d'un monopole amont menace par un concurrent etranger. Pour des couts de...

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in production.
