Beauty Contests and Asset Prices under Asymmetric Information

概要

論文の詳細を見る
In this paper, we study a dynamic Gaussian financial market model in which the traders form higher-order expectations about the fundamental value of a single risky asset. Rational uninformed traders are introduced into an otherwise standard differential information economy to investigate the impact of asymmetric information. In a two-period economy, there is a unique linear equilibrium; beauty contests under asymmetric information do not introduce excess volatility driven by self-fulfilling multiple equilibria. Under certain conditions, there is a nonmonotonic relationship between price volatility and the proportion of uninformed traders.
