In this paper, human capital investments are evaluated by assuming heterogeneous returns to education. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

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...

This paper investigates the impact of a high school degree on the wage distribution in the period from 1984 to 2004 in Germany. In that period the share of male workers with a high school degree increased from 16 to 25 percent. An econometric evaluation estimator is used to analyze quantile...

We estimate the effects of hiring subsidies for older workers on transitions from unemployment to employment in Germany. Using a natural experiment, our first set of estimates is based on a legal change extending the group of eligible unemployed persons. A subsequent legal change in the opposite...

Der Management Approach ist ein zentrales Rechnungslegungsprinzip innerhalb der IFRS. Zunächst in den 1990er-Jahren in der Diskussion um die Segmentberichterstattung nach SFAS 131 eingeführt und später in IAS 14 übernommen, wird der Begriff Management Approach heute in einem weiteren...

Summary 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...

This dissertation introduces three novel approaches for the econometric evaluation of heterogeneous treatment effects. The proposed methods consider the effects of a binary treatment on different characteristics of the outcome distribution.Section 1 proposes an estimation method for various...

Dieses Papier beschreibt Ergebnisse einer Evaluation von Eingliederungszuschüssen (EGZ) und Entgeltsicherung für ältere Arbeitnehmer. Es wird untersucht, ob förderberechtigte Personen im Vergleich zur Situation ohne diese Instrumente früher aus Arbeitslosigkeit in Beschäftigung wechseln....

In this paper, we investigate the relationship between individuals' willingness to take risk and job mobility during the early career. Job change is a risky decision since it involves substantial costs without entirely foreseeing the benefits at the time the decision is made. We incorporate risk...
