In this paper I develop a theoretical model explaining optimal wage-tenure profiles for heterogeneous labor. My findings entail that high productive people have steeper profiles than low productive individuals. I find strong empirical evidence for these findings. At the end of my paper, I...

While there is a broad literature on the general wage effect of training, little is known about the effects of different training forms and about the effects for heterogeneous training participants. This study therefore adds two aspects to the literature on earnings effects of training. First,...

Diese Arbeit untersucht empirisch den Zusammenhang von Beschäftigung und Lohnstrukturen zwischen sowie innerhalb von Qualifikations- und Altersgruppen. Zunächst werden Substitutionselastizitäten zwischen Qualifikations- und Altersgruppen geschätzt und die Lohnveränderungen bestimmt, die...

Empirical work on the wage impact of training has noted that unobserved heterogeneity of training participants should play a role. The expected return to training, which partly depends on unobservable characteristics, is likely to be a crucial criterion in the decision to take part in training...

The paper integrates human-capital investments of heterogeneous individuals into a neoclassical growth framework. The accumulation of physical capital changes relative factor prices and thus incentives to acquire skills, thereby altering the composition of the labor force. This interplay between...

According to empirical studies, the relation between the relative wage of skilled workers and their relative supply is U-shaped. This finding is explained by the effect of technological change on the incentives for humancapital investments made by heterogeneous individuals.
