Abstract

The Walrasian model has played a central role in all aspects of economics. The purpose of this paper is to propose a general modeling of differential information in the spirit of the Arrow-Debreu model and following the Radner tradition but away from the usual measurability conception. We provide a characterization of better informed agents in order to firstly formalize an essential feature known as part of some oral tradition: a decisionmaker prefers more information to less.
