WebMar 30, 2005 · In this paper we provide an asymptotic analysis of generalized bipower measures of the variation of price processes in financial economics. These measures encompass the usual quadratic variation, power variation, and bipower variations that have been highlighted in recent years in financial econometrics. The analysis is carried … WebVolatility Decomposition. Asset prices are usually modeled as a continuous diffusion process with random jumps. By decomposing an asset's price variance into continuous and jump components, better risk management and asset allocation for a portfolio can be achieved. In order to compute price variations, returns are first calculated and ...

We establish consistency of these estimators for the true unobserved volatility and the change points locations under general sub …
