Eine Methode, um das systematische und unsystematische Risiko sowie den Einfluss externer Einflussfaktoren auf Aktienrenditen zu bestimmen, ist die Zerlegung der Varianz von Aktienrenditen. Allerdings waren die bisher angewendeten Methoden der Varianzzerlegung nur unzureichend dazu geeignet,...

A small strand of recent literature is occupied with identifying simultaneity in multiple equation systems through autoregressive conditional heteroscedasticity. Since this approach assumes that the structural innovations are uncorrelated, any contemporaneous connection of the endogenous...

In the literature of identifcation through autoregressive conditional heteroscedasticity, Weber (2008) developed the structural constant conditional correlation (SCCC) model. Besides determining linear simultaneous influences between several variables, this model considers interaction in the...
