Estimation of Integrated Covariances in the Simultaneous Presence of Nonsynchronicity, Microstructure Noise and Jumps
We propose a new estimator for the integrated covariance of two Ito semimartingales observed at a high-frequency. This new estimator, which we call the pre-averaged truncated Hayashi-Yoshida estimator, enables us to separate the sum of the co-jumps from the total quadratic covariation even in the case that the sampling schemes …
