Keywords: ract: In his work on signaling Spence proposed a dynamic model of a market in which a buyer revises prices in light of experience and in which sellers with private information about their types choose utility-maximizing signals given these prices. We follows Spence's suggestion of introducing perturbations into the resulting dynamic process. In a broad class of markets our model selects a separating equilibrium outcome if and only if the equilibrium outcome satisfies a version of the undefeated equilibrium concept whereas a pooling equilibrium outcome is selected if and only if the equilibrium outcome is both undefeated and satisfies D1.
