This study explores the relationship between realized variance jump risk and conditional equity risk premium. Using high frequency records of the Standard & Poor's 500 index, we construct a realized variance measure and estimate its jump component using a Heterogeneous Autoregressive model...

We uncover significant asymmetric effects of realized jump risks on conditional equity premium. Negative or ``bad'' (positive or ``good'') jumps predict a rising (falling) near-term equity premium. The signed jump risk measures remain statistically significant even when we control for the...
