We study extrinsic and intrinsic motivations for tax compliance in the context of a local church tax in Germany. This tax system has historically relied on zero deterrence so that any compliance at baseline is intrinsically motivated. Starting from this zero deterrence baseline, we implement a field experiment that incentivized compliance through deterrence or rewards. Using administrative records of taxes paid and true tax liabilities, we use these treatments to document that intrinsically motivated compliance is substantial, that a significant fraction of it may be driven by duty-to-comply preferences, and that there is no crowd-out between extrinsic and intrinsic motivations.

Matching university places to students is not as clear cut or as straightforward as it ought to be. By investigating the matching algorithm used by the German central clearinghouse for university admissions in medicine and related subjects, we show that a procedure designed to give an advantage to students with excellent school grades actually harms them. The reason is that the three-step process employed by the clearinghouse is a complicated mechanism in which many students fail to grasp the strategic aspects involved. The mechanism is based on quotas and consists of three procedures that are administered sequentially, one for each quota. Using the complete data set of the central clearinghouse, we show that the matching can be improved for around 20% of the excellent students while making a relatively small percentage of all other students worse off.

Several German states recently introduced tuition fees for university education.We investigate whether these tuition fees influence the mobility of university applicants. Based on administrative data of applicants for medical schools in Germany, we estimate the effect of tuition fees on the probability of applying for a university in the home state. We find a small but significant reaction: The probability of applying for a university in the home state falls by 2 percentage points (baseline: 69%) for high-school graduates who come from a state with tuition fees. Moreover, we find that students with better high-school grades react more strongly to tuition fees. This might have important effects on the composition of students across states.

Quotas for special groups of students often apply in school or university admission procedures. This paper studies the performance of two mechanisms to implement such quotas in a lab experiment. The first mechanism is a simplified version of the mechanism currently employed by the German central clearinghouse for university admissions, which first allocates seats in the quota for top-grade students before allocating all other seats among remaining applicants. The second is a modified version of the student-proposing deferred acceptance (SDA) algorithm, which simultaneously allocates seats in all quotas. Our main result is that the current procedure, designed to give top-grade students an advantage, actually harms them, as students often fail to grasp the strategic issues involved. The modified SDA algorithm significantly improves the matching for top-grade students and could thus be a valuable tool for redesigning university admissions in Germany.
