The Core of Economies with Asymmetric Information: An Axiomatic Approach

    (Department of Economics, Brown University, and Department of Economics, Hebrew University of Jerusalem.)

We propose two generalizations of the Davis-Maschler reduced game property to economies with asymmetric information and apply them in the characterization of two solution concepts. One is Wilson's (1978) Coarse Core and the other is a subsolution of it which we call the Coarse+ Core.
