Abstract

In this paper, we define a new estimator of the leverage stochastic process based only on a pre-estimation of the Fourier coefficients of the volatility process. This feature constitutes a novelty in comparison with the leverage estimators proposed in the literature generally based on a pre-estimation of the spot volatility. Our estimator is proved to be consistent and in virtue of its definition it can be directly applied to estimate the leverage effect in case of irregular trading observations of the price path and microstructure noise contaminations.
