This study supplies new evidence regarding the predictive power of jumps for conditional market returns and volatilities. We change the constant jump intensity as in the Liu et al. and Du models with time-varying intensity following an autoregressive conditional jump intensity process and a...

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 investigate the asymptotic properties of an existing high frequency realized skewness measure and propose a more reliable new estimator which is robust to the microstructure noise at ultra-high frequency level. Asymptotic theory for the new estimator has been derived. Simulation example...

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...
