realized volatility. The jump component has very different time series properties than the continuous component, and accounting … for this allows improved forecasting of future realized volatility. We investigate the potential forecasting role of … implied volatility backed out from option prices in the presence of these new separate realized volatility components. We show …

market indices are analysed: DAX30 (Germany), FTSE100 (UK), CAC40 (France), FTSE MIB40 (Italy) and IBEX35 (Spain). In all …

We consider semiparametric frequency domain analysis of cointegration between long memory processes, i.e. fractional … cointegration, allowing derivation of useful long-run relations even among stationary processes. The approach is due to Robinson …-run dynamics. We derive the asymptotic distribution theory for the FDLS estimator of the cointegration vector in the stationary …
