Recent developments allow a nonparametric separation of the continuous sample path component and the jump component of realized volatility. The jump component has very different time series properties than the continuous component, and accounting for this allows improved forecasting of future...

This paper presents empirical evidence that the corporate bond market is forward looking with respect to volatility. I use the Merton (1974) model to calculate a measure of implied volatility from corporate bond yield spreads. I find that corporate bond transaction prices contain substantial...

This note presents the R package bayesGARCH (Ardia, 2007) which provides functions for the Bayesian estimation of the parsimonious and effective GARCH(1,1) model with Student-t innovations. The estimation procedure is fully automatic and thus avoids the tedious task of tuning a MCMC sampling...
