We assess the relevance of formal education for the productivity of the self-employed and distinguish between opportunity entrepreneurs, who voluntarily pursue a business opportunity, and necessity entrepreneurs, who lack alternative employment options. We expect differences in the returns to...

This paper analyzes the effect of alternative transition paths after grade 9 of German lower secondary school on vocational training. Using a selection-on-observables approach I show that a delayed transition into vocational training after lower track secondary school is not a disadvantage...

This study focuses on the role of heterogeneity in network peer effects by accounting for network-specific factors and different driving mechanisms of peer behavior. We propose a novel Multivariate Instrumental Variable (MVIV) estimator which is consistent for a large number of networks keeping...

One of the most important policy goals in industrialized countries is to increase the skill level of the labor force by life-long-learning strategies. In this paper our aim is to explain to what extent the variation in training investments is determined either by (observed and unobserved)...

Previous work has documented that speaking one's native language with an accent distinct from the mainstream is associated with lower wages. In this study, we seek to estimate the causal effect of speaking with a distinctive regional accent, disentangling the effect of the accent from that of...

The German apprenticeship training system is generally acknowledged to solve the youth unemployment problem prevalent in many European countries by providing on-the-job training that often leads into subsequent regular employment within the training firms. Little attention has been paid to those...

This paper explores the potential of an approach suggested by Manski of obtaining nonparametric bounds for treatment effects in evaluation studies without knowledge of the participation process. The practical concern is the effects of continuous vocational training in East Germany. The empirical...

The development of the West German earnings distribution in the 1980's is analysed on the basis of both the German Socio-Economic Panel and micro-data from the Employment Register of the Federal Labour Office. We find that earnings inequality in Germany has increased very little in the 1980's,...

Academic education is generally rewarded by employers, but what happens to graduates if they are trained for two years less and have to compete with vocationally trained labor market entrants in a similar field of study? Focusing on Germany, we analyze labor market entries of individuals...

As skills of labor-market entrants are usually not directly observed by employers, individuals acquire skill signals. To study which signals are valued by employers, we simultaneously and independently randomize a broad range of skill signals on pairs of resumes of fictitious applicants among...
