We propose an affine term structure model that allows for tenor-dependence of yield curves andthus for different risk categories in interbank rates, an important feature of post-crisis interestrate markets. The model has a Nelson-Siegel factor loading structure and thus economicallywell...

Energy price volatilities and correlations have been modeled extensively using short-memory multivariate GARCH models. This paper investigates the potential benefits from using multivariate fractionally integrated GARCH models from a forecasting and a risk management perspective. Several...

This paper studies the impact of modelling time-varying variances of stock returns in terms of risk measurement and extreme risk spillover. Using a general class of regime-dependent models, we find that volatility can be disaggregated into distinct components: a persistent stable process with...
