The Effects of Tuition Fees on Study Duration and Completion in the Population of German Students

This paper estimates the causal effects of fees on the duration of study and completion probabilities for an entire country. The empirical analysis merges difference-in-differences estimation with duration analysis to exploit an unusual natural policy experiment, namely the introduction of fees for university studies in several German states that also applied to enrolled cohorts. Our strategy allows uncovering effects of fees on the intensive margin, while holding constant extensive margin responses such as changes in the composition of the student body or migration responses that occur due to fees. We find that even modest fees have large and significant impacts on study duration and completion rates on students who enrolled before fees were introduced.

The impact of affirmative action on fairness perception and on-the-job search: evidence from linked employer-employee data

One striking example of gender inequalities in the labor market are substantial gender differences in management positions. In this paper we identify the impact of a firm-level gender quota on behavioral outcomes of employees. We use representative employer-employee survey data to figure out whether the implementation of a gender quota has an impact on the fairness perception and the on-the-job search behavior of men and women. We identify the existence of a gender quota by using the implementation of a law that aims to increase gender equality in management positions in Germany. Our results show a reduction of fairness perception and an increase in turnover intention among men and women. Effects are more pronounced among employees with a higher probability to be affected by the quota. Effects on on-the-job search are only partially explained by affective behavior and might be explained by a shift in outside options.

Preferences over Taxation of High Income Individuals: Evidence from Online and Laboratory Experiments (with Eckhard Janeba, Lydia Mechtenberg, Nils Wehrhöfer)

Mobility of high income individuals across borders puts pressure on governments to lower taxes. A central tenet of the underlying theoretical and empirical models is that mobile individuals react to tax differentials through migration, and in turn immobile households vote for lower taxes in the face of a migration threat. In light of behavioural economics research it is not clear, however, whether this premise holds. In particular, political ideology might influence voting on taxes. We use an experimental survey design and elicit answers from more than 3,000 households in the German Internet Panel (GIP). We use various treatments to understand the role of mobility and ideology in tax choice. We observe substantial deviations from the predicted theoretical equilibrium. In many cases comparative static results prevail, however. Furthermore, political ideology matters: left-leaning households choose higher taxes than right-leaning persons, and center-right leaning individuals tend to emigrate more when the tax at home is high. We compare the results with those from a closely related lab experiment, in which subjects appear to behave more in line with standard predictions.

A model for scheduling with activity failures

An R&D project typically consists of several stages.  Due to technological risks, the project may have to be terminated before completion, each stage having a specific likelihood of success.  In the project planning and scheduling literature, this technological uncertainty has typically been ignored and project plans are developed only for scenarios in which the project succeeds.  In this work we examine how to schedule projects in order to maximize their expected net present value when the project activities have a probability of failure and when an activity’s failure leads to overall project termination.  We describe a general model, develop an exact algorithm and establish a link with stochastic scheduling.
