When alternatives are compared using an estimated criterion function, this may introduce a discrepancy between the true and the estimated criterion. In this paper, we consider a situation where a preordering (ranking) of stochastic sequences is defined from expected loss/gain, using a parametric...

Der erste Aufsatz der vorliegenden Dissertation untersucht die Dynamik der realisierten Volatilität. Ein erfolgreiches Model in diesem Bereich ist das sogenannte heterogene auto-regressive Modell (HAR), das konzeptionell einfach und gut für Vorhersagen geeignet ist. Eine neue Herangehensweise...

We investigate the presence of international business cycles in macroeconomic aggregates (output, consumption, investment) using a panel of 60 countries over the period 1961 - 2014. The paper presents a Bayesian stochastic factor selection approach for dynamic factor models with predetermined...

A large number of nonlinear conditional heteroskedastic models have been proposed in the literature. Model selection is crucial to any statistical data analysis. In this article, we investigate whether the most commonly used selection criteria lead to choice of the right specification in a...
