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 present and prove the equality between the core and the set of Walras allocations for a pure exchange economy with l goods and a continuum of consumers, represented by an atomless measure space.

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...

Ce texte constitue un complement a la presentation generale, non formelle, du modele CLFPSR faite dans [6]. Il contient une presentation systematique de la structure du modele, en termes d'economie mathematique, quoique elementaires: types de donnees et de variables, systeme de contraintes,...

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 information, a continuum of states and an infinite...

This paper presents a surprising example. It shows that lattice theoretic properties in Mas-Colell's (1986) seminal work are relevant to the existence of equilibrium problem even when commodity space is finite dimensional. The paper provides an example of an economy with three commodities and...

We consider a general equilibrium model with a production sector. The consumption sets, the preferences of the consumers and the production possibilities are represented by set-valued mappings to take into account the possibility of external effects. There are no convexity assumptions on the...

In this paper we generalize Magill and Shafer's analysis of generically complete markets in the presence of an open-ended horizon. Until now, the genericity argument in Duffie and Shafer has no satisfactory generalisation to the case of an open ended horizon. These difficulties are threefold:...

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...

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,...
