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...

This paper analyzes optimal linear taxes on capital and labor incomes in a life-cyclemodel of human capital investment, financial savings, and labor supply with heteroge-nous individuals. A dual income tax with a positive marginal tax rate on not onlylabor income but also capital income is...

I consider two different skill accumulation technologies, learning by doing and Ben-Porath type training. The effect of human capital accumulation in the form of learning by doing is to increase the labor supply elasticity estimate by a factor of 2.1 relative to the estimate that ignores human...

This paper presents and estimates a unified model where both human capital investment and job search are endogenized. This unification enables us to quantify the relative contributions of each mechanism to life cycle earnings growth, while investigating potential interactions between human...

This review article examines the role of labor income risk in determining the value of a person’s human capital. We draw on the existing literature to present a model that incorporates various types of shocks to earnings. Within this framework, we highlight the implications of different...

Human Capital over the Life Cycle: A European Perspective identifies the problem of human capital creation as one of the fundamental issues in the development of knowledge-based economies.

In this paper, we analyse the human capital accumulation process over the life cycle of individuals under the hypothesis of earnings uncertainty. To do so, we develop a continuous time dynamic programming model which takes into account several sources of uncertainty, concerning the human capital...
