Rate-Amplifying Demand and the Excess Sensitivity of Long-Term Rates

We present an extrapolative model of bubbles. In the model, many investors form their demand for a risky asset by weighing two signals: an average of the asset’s past price changes and the asset’s degree of overvaluation. The two signals are in conflict, and investors...
