The standard equivalence result on core and Walras equilibrium allocations uses a non-satiation and an interiority assumption. Konovalov introduced the rejective core for exchange economies with possibly satiated preferences and proved that there, the fuzzy rejective core coincides with the set...

Cet article se propose d'examiner de maniere detaillee les productivites du travail au niveau sectoriel et agrege pour les regions francaises sur la decennie 80. Empruntant aux travaux inities par Baumol, suivis par Barro et Sala-i-Martin notamment, elle enrichit ces derniers en mettant l'accent...

In this paper, we formulate a restatement of the theory of choice under uncertainty. As an alternative to the rank-dependent expected utility model, we develop a probability-altering theory in which the transformation of probabilities is weighted by the centered outcome of the lottery which may...

Cet article s'inscrit dans la continuite des etudes recentes sur l'impact des variables ethniques sur la performance economique. Le canal des migrations y est explore, pour tenter d'expliquer la relation negative observee empiriquement entre variables ethniques et performance. Nous supposons des...

L'une des caracteristiques saillantes des mutations en cours dans plusieurs grands secteurs industriels ou de services (dereglementation des marches , globalisation croissante, changements technologiques radicaux) reside d ans la concomitance de deux mouvements apparemment contradictoires : d'un...

We study the problem of minimal initial capital needed in order to hedge a European contengent claim without risk. The financial market presents incompleteness arising from two sources: stochastic volatility and portfolio constraints described by a closed convex set. In contrast with previous...

The attitude of future generations towards environmental assets could be different from ours, and it is necessary to take into account explicitly this possibility in the current debate about environmental policy. The question we address here is : should uncertainty about future preferences lead...

Nous etudions les implications dynamiques de l'introduction d'effets de complementarite sur la croissance et les rythmes de progres technique dans un modele de croissance endogene par differenciation verticale. On considere deux biens complementaires dans la consommation, produits a partir de...

In this paper we investigate the importance of domestic nominal and real shocks on the fluctuations of the exchange rate and the current account balance in four countries : South Korea, Indonesia, Thailand and Mexico. We also analyse the effect of the budgetary deficit and the monetary policy on...

The purpose of this paper is to study how the equilibrium prices and allocations in a linear exchange economy vary with respect to the intial endowments and utility vectors. We characterize an open dense subject of full measure of the initial endowment and utility vector space on which the...
