Bubbles, Crashes and Risk
In an asset-pricing model, risk-averse agents need to forecast the conditional variance of a stock's return. A near-rational restricted perceptions equilibrium exists in which agents believe prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk in real time, recurrent bubbles and crashes can arise. These effects are stronger when agents allow for ARCH in excess returns.
