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...

This paper demonstrates that an asset pricing model with least-squares learning can lead to bubbles and crashes as endogenous responses to the fundamentals driving asset prices. When agents are risk-averse they need to make forecasts of the conditional variance of a stock¡¯s return....

Observed macroeconomic forecasts display gradual recognition of the long-run growth of endogenous variables (e.g. output, output per hour) and a positive correlation between long-run growth expectations and cyclical activities. Existing business cycle models appear inconsistent with the...
