Equilibrium theory with asymmetric information and inﬁnitely many states.

Monteiro, Paulo K.; Martins-da-Rocha, Victor-Filipe; … - Université Paris-Dauphine - 2009

Radner (1968) proved existence of a competitive equilibrium for differential information economies with ﬁnitely many states. We extend this result to economies with inﬁnitely many states of nature. Each agent observes a public and a private signal. The publicly observed signal may take...

Large economies with differential information and without free disposal.

Angeloni, Laura; Martins-da-Rocha, Victor-Filipe - Université Paris-Dauphine - 2009

We consider exchange economies with a continuum of agents and differential information about ﬁnitely many states of nature. It was proved in Einy, Moreno, and Shitovitz (2001) that if we allow for free disposal in the market clearing (feasibility) constraints then an irre- ducible economy has...

Payoff-dependant Balancedness and Cores.

Bonnisseau, Jean-Marc; Iehlé, Vincent - Université Paris-Dauphine - 2007

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff vectors satisfying this condition. The additional...

The ex ante incentive compatible core in the absence of wealth effects.

Forges, Françoise; Mertens, Jean-François; Vohra, Rajiv - Université Paris-Dauphine - 2002

In a differential information economy with quasi–linear utilities, monetary transfers facilitate the fulfillment of incentive compatibility constraints : the associated ex ante core is generically nonempty. However, we exhibit a well–behaved exchange economy in which this core is empty, even...

Endogenous asymmetries in technology adoption and international trade.

Ledezma, Ivan - Université Paris-Dauphine

This note explores the interaction between trade integration and asymmetric choices of technology adoption. It seeks to bring micro foundations of Örm heterogeneity into an open-economy model. By so doing, the analysis shows the complementarity between an imperfect competition framework of...

Equilibria in reflexive Banach lattices with a continuum of agents.

Araujo, Aloisio; Martins-da-Rocha, Victor-Filipe; … - Université Paris-Dauphine - 2004

We consider exchange economies with a measure space of agents and for which the commodity space is a separable and reflexive Banach lattice. Under assumptions imposing uniform bounds on marginal rates of substitution, positive results on core-Walras equivalence were established in...

Unicité et stabilité de l'équilibre dans une économie de production avec règle de tariﬁcation marginale : les cas convexe et non-convexe.

Jouini, Elyès - Université Paris-Dauphine - 1996

Dans cet article nous établissons une formule de l’indice pour une économie où les producteurs utilisent la tarification marginale et nous montrons que, sous des hypothèses de monotonicité sur la correspondance d’excès de demande et les conditions suffisantes du second ordre de...
