Im vorliegenden Beitrag wird von einem ökonomischen Standpunkt aus theoretischer Sicht untersucht, ob durch eine Lockerung des Kündigungsschutzes in Zeiten hoher Arbeitslosigkeit die Beschäftigung gesteigert werden kann, wenn die Antizipation eines hohen Kündigungsschutzes durch die...

In analysing time series of counts, the need to test for the presence of a dependence structure routinely arises. Suitable tests for this purpose are considered in this paper.

It is well known that credibility theory in discrete time is closely related to the discrete technique of Kalman filtering. In this paper we show the close relationship between credibility theory and filter theory in discrete and continuous time as well as between credibility theory in a...

The polychoric correlation is an ML estimator for the correlation parameter between two latent variables. Each latent variable is only observed as an ordered categorical indicator. This estimator is based on an assumption on the joint distribution for the latent variables which in this case is...

This paper presents theoretical models and their empirical results for the return and variance dynamics of German stocks. A factor structure is used in order to allow for a parsimonious modeling of the first two moments of returns. Dynamic factor models with GARCH dynamics (GARCH(1,1)-M,...

In this paper we examine small sample properties of a generalized method of moments (GMM) estimation using Monte Carlo simulations. We assume that the generated time series describe the stochastic variance rate of a stock index. We use a mean reverting square-root prooess to simulate the...

Ziel dieses Beitrags ist die Quantifizierung der Entscheidungswirkungen von Verlustverrechnungsbeschränkungen bei innerstaatlichen und grenzüberschreitenden Investitionsmöglichkeiten. Da die Vorteilhaftigkeit von Investitionen nur als relatives Maß anhand einer Unterlassungsalternative...
