This paper explores whether investments in information and communication technologies (ICT) and firm?sponsored training programmes are complementary. Three approaches are applied to panel data from German service companies for the time period 1994?98. Results for a system of interrelated factor...

This paper provides a labour supply explanation to the observation that in Germany employment changes are asymmetric during the business cycle. Employment increases are slower, because the reservation wage of workers increases in times of job uncertainty. Workers are afraid in those periods of...

This paper demonstrates that insiders can erect barriers to entry and skim rents by sinking costs in human capital when labour markets are otherwise perfectly contestable. The sunk costs nature of human capital investments may result from the need to satisfy ever increasing specialised skill...

We analyze a two-period modell where risk-averse students divide their time between risky education, leisure, and work. The educated can migrate. Wagetax financed transfer to students acts as an insurance, and increases both investment in education and demand for leisure. We drive sufficient...

Um Hinweise für die Erträge von Investitionen in die Fähigkeiten von Kindern im Vorschulalter geben zu können, möchten wir in diesem Beitrag die Ergebnisse von Simulationen zur Diskussion stellen. Der Humankapitalerwerb wird als Funktion von kognitiven und nichtkognitiven Fähigkeiten...

In der folgenden Studie möchten wir ausgewählte Aspekte von intra- und intergenerationalen Umverteilungseffekten im System der bundesdeutschen Alterssicherung auf der Basis der Humankapitalheorie mit Simulationsmethoden analysieren. Falls es das Ziel der Politik ist, die Ungleichheit des...

Labour market reforms that are designed to stimulate labour supply at the lower end of the wage distribution can never be precisely restricted to affect only the target group. Spillovers to and feedback from other segments of the labour market are unavoidable and may counteract the direct...

In the paper we describe in detail how to build linked CGE-microsimulation models (using fictitious data) following three main approaches: one in accordance with the fully integrated approach and the other two according to the layered approach – the so-called Top-Down and Top-Down/Bottom-Up...

Current political discussions in Germany and other European countries illustrate the importance accorded to revenue and distribution effects of tax reforms. Whereas widely recognized concepts of effective tax measures can provide important insights into the incentives of taxation they do not...
