This paper introduces new core and Walrasian equilibrium notions for an asymmetric
information economy with non-expected utility preferences. We prove existence and …

The second welfare theorem and the core-equivalence theorem have been proved to be
fundamental tools for obtaining equilibrium existence theorems, especially in an infinite …

We study exchange economies in ordered normed spaces (X,‖⋅‖) where agents have
possibly different consumption sets. We define the notion of semi-interior point of the positive …

In this paper, we prove a new version of the Second Welfare Theorem for economies with a
finite number of agents and an infinite number of commodities, when the preference …

Compendious and thorough solutions to the existence of a linear price equilibrium problem,
the second welfare theorem, and the limit theorem on the core are provided for exchange …

We use in this paper the viability/capturability approach for studying the problem of
characterizing the dynamic core of a dynamic cooperative game defined in a characteristic …

We introduce differential information in the asset market model studied by Cheng J Math
Econ 20 (1): 137–152, 1991, Dana and Le Van J Math Econ 25 (3): 263–280, 1996 and Le …

Abstract Debreu and Scarf (Int Econ Rev 4: 235–246, 1963) proved that for an exchange
economy or a production economy with the same production set for all coalitions, under …

In this note, we give an equilibrium existence theorem for exchange economies with
asymmetric information and with an infinite dimensional commodity space. In our model, we …

This paper studies production economies in a commodity space that is an ordered locally
convex space. We establish a general theorem on the existence of equilibrium without …
