Das Optionspreismodell von Black/Scholes hat sich zum Industrie-Standard für die Bewertung von Aktienoptionen entwickelt. In diesem Modell wird die Annahme einer konstanten Volatilität der Kursveränderungen getroffen. Der Befund zahlreicher empirischer Untersuchungen, dass sich Volatilität...

In this paper, we review the most common specifications of discrete-time stochastic volatility (SV) models and illustrate the major principles of corresponding Markov Chain Monte Carlo (MCMC) based statistical inference. We provide a hands-on ap proach which is easily implemented in empirical...

In this paper we replace the Gaussian errors in the standard Gaussian, linear state space model with stochastic volatility processes. This is called a GSSF-SV model. We show that conventional MCMC algorithms for this type of model are ineffective, but that this problem can be removed by...

This paper presents an estimated DSGE model for the European Monetary Union. Our approach, contrary to the previous studies, accounts for heterogeneity within the euro area. We advance the empirical literature by estimating an open-economy model with unfiltered data, which is a much more...
