Most affine models of the term structure with stochastic volatility (SV) predict that the variance of the short rate is simultaneously a linear combination of yields and the quadratic variation of the spot rate. However, we find empirically that the A1(3) SV model generates a time series for the...

The stylized fact that volatility is not priced in individual equity options does not withstand scrutiny. We show, first, that the average return of heavily traded deep out-of-the-money call options on stocks is -116 basis points per day. Second, Fama- MacBeth estimates of the volatility risk...
