Existence and regularity of partially revealing rational expectations equilibrium in finite economies
The paper under review deals with the model of incomplete financial market exchange economy. Nominal assets and finite number of traders, goods, states and signals are assumed. The main goal of the paper is to prove the existence and regularity of rational expectation equilibria for any informational structure that can be derived from prices. In the sense of this goal the characterization of the existence of an equilibrium is completed. The proof of the main result is based on homotopy methods.
