In this paper, we extend the concept of News Impact Curve developed by Engle and Ng (1993) to the higher moments of the multivariate returns' distribution, thereby providing a tool to investigate the impact of shocks on the characteristics of the subsequent distribution. For this purpose, we...

Neben der Einleitung ist die Dissertation in zwei Teile aufgeteilt. In Teil I wird die Annahme eines Investors mit μ-σ Präferenz getroffen. Das erste Kapitel stellt ein Multi-Rating ATSM unter Arbitragefreiheit mit dem klaren Fokus auf Zinsstrukturkurvenmodelle für Unternehmensanleihen vor....

The use of GARCH models with stable Paretian innovations in financial modeling has been recently suggested in the literature. This class of processes is attractive because it allows for conditional skewness and leptokurtosis of financial returns without ruling out normality. This contribution...

The Normal Inverse Gaussian (NIG) distribution recently introduced by Barndorff-Nielsen (1997) is a promising alternative for modelling financial data exhibiting skewness and fat tails. In this paper we explore the Bayesian estimation of NIG-parameters by Markov Chain Monte Carlo Methods. --...
