value robust volatility estimator with respect to the standard robust volatility estimator as proposed in the paper by … Muneer & Maheswaran (2018b). We show that the robust volatility ratio is unbiased both in the population as well as in finite … samples. We empirically test the robust volatility ratio on 9 global stock indices from America, Asia Pacific and EMEA markets …

theory assumes that return shocks can be caused by changes in conditional volatility through a time-varying risk premium. On … leverage effect and the volatility feedback effect. We stress the importance of distinguishing between realized volatility and … implied volatility, and find that implied volatilities are essential for assessing the volatility feedback effect. The …

implications from a long-run risk model incorporating both time varying volatility and volatility uncertainty. We provide new … direct estimation of the underlying “structural” shocks and economic transmission mechanisms, including a new volatility …

A rapidly growing literature has documented important improvements in volatility measurement and forecasting … provides a practical framework for non-parametrically measuring the jump component in realized volatility measurements … an easy-to-implement reduced form model for realized volatility results in highly significant jump coefficient estimates …

frequency can be obtained almost as precisely as if volatility is observable by simply incorporating the strong information … content of realized volatility measures extracted from high-frequency data. For this purpose, we introduce asymptotically … exact volatility measurement equations in state space form and propose a Bayesian estimation approach. Our highly efficient …

Following recent advances in the non-parametric realized volatility approach, we separately measure the discontinuous … volatility models. We analyze the distributional properties of the jump measures vis-à-vis the corresponding realized volatility … accuracy of high-frequency volatility models …

The VIX index is not only a volatility index but also a polynomial combination of all possible higher moments in market …
