Impact of jumps on returns and realised variances: econometric analysis of time-deformed Lévy processes

In order to assess the effect of jumps on realised variance calculations, we study some of the econometric properties of time-changed Lévy processes. We show that in general realised variance is an inconsistent estimator of the time-change, however we can derive the second-order properties of realis...
