Stochastic Volatility (SV) models are widely used in financial applications. To decide whether standard parametric …

This paper offers a new approach for estimation and forecasting of the volatility of financial time series. No … assumption is made about the parametric form of the processes, on the contrary we only suppose that the volatility can be … homogeneity, then the estimate of the volatility can be simply obtained by local averaging.

In contrast to U.S. data we … find that the volatility depends on either the interest rate level or information shocks but not on both. Finally, we … propose to describe the short term interest rate's dynamics by means of an AR(1) model with stochastic volatility. -- Term …
