We provide empirical evidence of volatility forecasting in relation to asymmetries present in the dynamics of both return and volatility processes. Using recently-developed methodologies to detect jumps from high frequency price data, we estimate the size of positive and negative jumps and...

In this paper we propose a smooth transition tree model for both the conditional mean and variance of the short-term interest rate process. The estimation of such models is addressed and the asymptotic properties of the quasi-maximum likelihood estimator are derived. Model specification is also...

We propose a simple but effective estimation procedure to extract the level and the volatilitydynamics of a latent macroeconomic factor from a panel of observable indicators. Our approachis based on a multivariate conditionally heteroskedastic exact factor model that cantake into account the...

We propose an empirical approach to determine the various economic sourcesdriving the US yield curve. We allow the conditional dynamics of the yield at differ-ent maturities to change in reaction to past information coming from several relevantpredictor variables. We consider both endogenous,...
