contribution of this paper is twofold. First, it provides a bivariate asymptotic limit theory for realised variance and realised … asymptotic variance of the estimation bias. Eventually, this leads to a feasible asymptotic theory which is applicable in … practice. Finally, Monte Carlo studies reveal a good finite sample performance of the proposed feasible limit theory. …

This paper studies the effect of time–inhomogeneous jumps and leverage type effects on realised variance calculations when the logarithmic asset price is given by a Lévy–driven stochastic volatility model. In such a model, the realised variance is an inconsistent estimator of the integrated...

We show that the compensation for rare events accounts for a large fraction of the equity and variance risk premia in … market volatility, but the risk premium for tail events cannot solely be explained by the level of the volatility. Our … probability measure from "medium" size jumps in high-frequency intraday prices and an extreme value theory approximation for the …

This paper introduces the concept of stochastic volatility of volatility in continuous time and, hence, extends standard stochastic volatility (SV) models to allow for an additional source of randomness associated with greater variability in the data. We discuss how stochastic volatility of...

We propose a new and flexible non-parametric framework for estimating the jump tails of Itô semimartingale processes. The approach is based on a relatively simple-to-implement set of estimating equations associated with the compensator for the jump measure, or its "intensity", that only...

This paper presents some limit theorems for certain functionals of moving averages of semimartingales plus noise, which are observed at high frequency. Our method generalizes the pre-averaging approach (see [13],[11]) and provides consistent estimates for various characteristics of general...

We consider a new class of estimators for volatility functionals in the setting of frequently observed Itô diffusions which are disturbed by i.i.d. noise. These statistics extend the approach of pre-averaging as a general method for the estimation of the integrated volatility in the presence of...
