240 Schulleiter wurden nach ihren Erwartungen und Ansprüchen gegenüber ihren Lehrpersonen befragt. Eine Clusteranalyse ergab zwei Gruppen von Schulleitern: An Schuladministration und Schulordnung orientierte (Gruppe I) und eher pädagogisch geleitete Schulleiter (Gruppe II). Die Schulleiter...

Angesichts des demographischen Wandels gewinnen die Verlängerung der Erwerbstätigkeit und damit auch die Bedingungen für Neueinstellungen im letzten Drittel des Erwerbslebens an Bedeutung. Dieser Beitrag untersucht auf mikroökonomischer Grundlage (IABBetriebspanel) betriebliche Merkmale, die...

Der vorliegende Beitrag untersucht die Wirkung von unternehmerischen Work-Life Balance Initiativen für die emotionale Bindung der Mitarbeiter zum Unternehmen, d. h. das organisationale Commitment von Mitarbeitern im Kontext der Unternehmensberatung. Dazu wurde eine Untersuchung mit insgesamt...

Using data from Germany, Japan, UK, and the U.S., we explore possible threshold cointegration in nominal short- and long-run interest rates with corresponding inflation rates. Traditional cointegration implies perfect mean reversion in real rates and hence confirms the Fisher hypothesis....

The empirical joint distribution of return-pairs on stock indices displays high tail-dependence in the lower tail and low tail-dependence in the upper tail. The presence of tail-dependence is not compatible with the assumption of (conditional) joint normality. The presence of asymmetric-tail...

This paper questions traditional approaches for testing the day-of-the-week effect on stock returns. We propose an alternative approach based on the closure test principle introduced by Marcus, Peritz and Gabriel (1976), which has become very popular in Biometrics and Medical Statistics. We test...

Recent attention has focused on the UK's productivity gap in the retail sector. Figure 1 shows an estimate of labour productivity in retail across countries, using output per hour worked. The UK lies well behind the US, France and Germany. Reynolds at al (2005) contribute to this debate by...

In this paper we study the sources of wage growth. We identify the contribution to such growth of general, sector specific and firm specific human capital. Our results are interpretable within the context of a model where the returns to human capital may be heterogeneous and where firms may...

We study the role of establishment-specific wage premiums in generating recent increases in West German wage inequality. Models with additive fixed effects for workers and establishments are fit in four sub-intervals spanning the period from 1985 to 2009. We show that these models provide a good...

In this article we demonstrate how challenging greenhouse gas reduction targets of up to 95% until 2050 can be achieved in the German electricity sector.1 In the analysis, we focus on the main requirements to reach such challenging targets. To account for interdependencies between the...
