Edgeworth and Walras Equilibria of an Arbitrage-Free Exchange Economy.

Allouch, N.; Florenzano, M. - Centre de recherche de mathématiques et économie … - 2000

In this paper, we first give a direct proof of the existence of Edgeworth equilibria for exchange economies with consumption sets which are (possibly) unbounded below. The key assumption is that the individually rational utility set is compact. It is worth noticing that the statement of this...

A General Nonemptiness Result of the Core of a Production Economy with Asymmetric Information.

Lefebvre, I. - Centre de recherche de mathématiques et économie … - 1999

The core of an economy consists of those attainable allocations of the economy which no group of agents (coalition) can … "improve upon". This paper presents a concept of core of a production economy with a finite number of agents with asymmetric … core of this economy. The proof is based on a (quasi) fixed point theorem. …

Semi-Algebraic Economies

Giraud, G. - Centre de recherche de mathématiques et économie … - 1997

This paper studies geometric properties of semi-algebraic economies with (eventually nonconvex) production - a class which includes linear or Cobb-Douglas preferences, polyhedric production sets and indivisible commodities as well. The main departure with the textbook differentiable viewpoint is...

Competitive Strategic Market Games with an Infinite-Dimensional Trade Space

Giraud, G. - Centre de recherche de mathématiques et économie … - 1997

This paper constructs two feasible strategic market games associated to an economy with infinite-dimensional trade space, finitely many traders, and finitely many firms, such that the set of outcomes induced by pure Nash equilibria coincides with the set of competitive equilibria. In both games,...

Production equilibria in vector lattices : a general approach.

Florenzano, M.; Marakulin, V. - Centre de recherche de mathématiques et économie … - 2000

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.

The Connection Between Correlated and Sunspot Equilibria Revisited.

Davila, J. - Centre de recherche de mathématiques et économie … - 1999

This paper shows how to make hold the conjecture stated in Maskin an Tirole about the existence of a close connection between the finite, markovian stationary equilibria of a simple overlapping generations economy and the correlated equilibria of an associated finite exchange economy with...

Sharing Beliefs: Between Agreeing and Disagreeing

Billot, A.; Chateauneuf, A.; Gilboa, I.; Tallon, J.-M. - Centre de recherche de mathématiques et économie … - 1998

In an exchange economy with no aggregate uncertainty, and Bayesian agents, Pareto optimal allocations provide full insurance if and only if the agents have a common prior. It is hard to explain why there is relatively so little betting taking place. One is led to ask, when are full insurance...
