Regular infinite economies
Covarrubias, Enrique - 2010
The main contribution of this paper is to place smooth infinite economies in the setting of the equilibrium manifold and the natural projection map à la Balasko. We show that smooth infinite economies have an equilibrium set that has the structure of a Banach manifold and that the natural...

The number of equilibria of smooth infinite economies
Covarrubias, Enrique - 2011
We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria. -- Uniqueness ; determinacy ; equilibria ; infinite...

An extension of the sard-smale theorem to domains with an empty interior
Accinelli, Elvio; Covarrubias, Enrique - 2013
A stumbling block in the modelling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of...

A Unified Treatment of Finite and Infinite Economies : Limited Arbitrage is Necessary and Sufficient for the Existence of Equilibrium and the Core
Chichilnisky, Graciela; Heal, Geoffrey M. - 2011
A single condition, limited arbitrage, is shown to be necessary and sufficient for the existence of a competitive equilibrium and the core in economies with any number of markets, finite or infinite, with or without short sales. This extends earlier results of Chichilnisky for finite economies....
