Abstract

We introduce a general equilibrium model with potentially inefficient stock markets consisting of asymmetrically informed investors. Prices are sticky in the goods market, but the labor market adjusts perfectly. The central bank aims to maximize the life-time wealth of the households in every period by keeping inflation in the steady state and stock markets in the fair value by adjusting the rate of return on risk-free investments. We find that the “leaning against the wind” policy works, which means that positive stock market bubbles can be eliminated by raising the risk-free rate.
