Sammendrag
In this note we extend Radner's ([6]) result on the revealing properties of a rational expectations equilibrium to the case of an infinite dimensional probability space. Radner's auxiliary proposition, which states that the set of probability assessments leading to the same equilibrium price is negligible, is generalised to the infinite dimensional case. In the original paper a set is negligible if its closure has Lebesgue measure zero in $\R^N$, while in our setting a set is negligible if it is a meagre subset of some topological space.
