摘要：

This talk proposes a consumption-based model to explain puzzling unstable, i.e., sometimes positive and sometimes      negative, relations between stock market variance with both market risk premia and prices. In the model, market risk       premia depend positively (negatively) on “fear” (“euphoria”) variance. Market prices, which decrease with discount    rates,correlate negatively (positively) with fear (euphoria) variance. Because it is the sum of fear and euphoria          variances,market variance may correlate positively or negatively with expected returns and prices, depending on the        relative importance of the two variances. Our empirical results support model’s key assumptions and many novel            implications.
