Abstract

We present some regularity properties (convexity, weak/weak∗ compactness and preservation of weak/weak∗ upper hemicontinuity) for Bochner/Gel′fand conditional expectation of Banach valued correspondences under the nowhere equivalence condition. These regularity properties for Bochner/Gel′fand integral of Banach valued correspondences are obtained as corollaries. We prove the necessity of the nowhere equivalence condition for any of these properties to hold. Economic applications, including a general class of large games and abstract economies with asymmetric information, are discussed.
