Partial Revelation with Rational Expectations

Abstract

For alternative specifications of an economy under uncertainty, we build a partially revealing Rational Expectations Equilibrium (REE). At equilibrium, no individual knows the state of the world or the quantities traded by other individuals. The combination of these partial revelation properties is not a feature of the examples of partial revelation in the literature. A general proposition characterizes the residual dimension of uncertainty at a smooth REE.
