Abstract

We study the informational role of prices in a stochastic environment. We provide a closed-form solution of the monopoly problem when the price imperfectly signals quality to the uninformed buyers. We then study the effect of noise on output, market price, information flows, and expected profits. The presence of noise may reduce the informational externality due to asymmetric information, which increases the firm's expected profits.
