Ziel des Programms ist es, zu einer möglichst breit wirksamen Sicherung und Verbesserung der Qualität des mathematisch-naturwissenschaftlichen Unterrichts und langfristig der mathematisch-naturwissenschaftlichen Bildung beizutragen. Dafür soll vorhandenes Wissen systematisch genutzt und der...

In many microeconometric models we use distances. For instance, in modelling the individual behavior in labor economics or in health studies, the distance from a relevant point of interest (such as a hospital or a workplace) is often used as a predictor in a regression framework. However, in...

In this paper, we run regression analyses to explain voluntary turnover intentions with data from more than 5,000 employees and with about 250 explanatory variables. The findings of our multi-factor approach highlight the fact that previous empirical research might have over-estimated the impact...

Good corporate reputation is seen as one of the most valuable assets. It is believed to cause a multitude of favorable impacts within different stakeholder groups. As a consequence, a multitude of studies analyzed the relationship between corporate reputation and financial performance. However,...

Using the statistical technique of fuzzy clustering, regimes of inflation and unemployment are explored for the United States, the United Kingdom and Germany between 1871 and 2009. We identify for each country three distinct regimes in inflation/unemployment space. There is considerable...

The aim of this paper is to examine the existence of short–run lead–lag effects between the spot and the futures market in the German stock exchange and particularly the DAX index, over the period 1/2000 - 12/2003, using intradaily data. As long as such relationships are established we...

Using recent advances in time-varying spectral methods, this research analyses the growth cycles of the core of the euro area in terms of frequency content and phasing of cycles. The methodology uses the continuous wavelet transform (CWT) and also Hilbert wavelet pairs in the setting of a...
