讲座介绍：
We develop a closed-form approach to examine the joint effect of “Keeping up with the Joneses” (KUJ) preferences and time-varying sentiment of heterogeneous beliefs on equilibrium asset price dynamics in a two-agent economy. We show that, due to KUJ, sentiment continues to have a significant effect on equilibrium asset price, though the sentiment-driven agent does not survive in the long run. When agents are pessimism on average, the model is able to generate countercyclical equity premiums, procyclical and concave price-dividend ratios, excess and countercyclical stock volatility similar to those observed in the U.S. equity market. In particular, an average of 0.7% (p.a.) underestimation of the expected GDP growth based on the Survey of Professional Forecasts can explain about half of market equity premium. Moreover, the term structure of real interest rates is upward (downward) sloping when the short rate is relatively low (high).
