This article proposes a novel approach to modelling structural changes in asset returns correlations and their relationship to macroeconomic fundamentals. We introduce a new correlation component model, the Regime-switching DCC-MIDAS, that incorporates breaks of different type in the conditional...

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...

We propose a novel approach to modelling structural changes in asset returns correlations. Our framework allows for breaks of different type in the conditional and unconditional correlation components by capturing abrupt regime switches in the short-run correlations and smooth transitions...
