This paper reports on a field experiment testing for sunk-cost effects in an education setting. Students signing up for extra-curricular tutorial sessions randomly received a discount on the tuition fee. The sunk-cost effect predicts that students who receive larger discounts will attend fewer...

This paper uses administrative data from 16 cohorts of the Dutch population to study the relationship between field of study and family outcomes. We first document considerable variation by field of study for a range of family outcomes. To get to causal effects, we use admission lotteries that...

We exploit admission lotteries to estimate the payoffs to the dentistry study in the Netherlands. Using data from up to 22 years after the lottery, we find that in most years after graduation dentists earn around 50,000 Euros more than they would earn in their next-best profession. The payoff is...

In this paper we investigate how heterogeneous agents choose among tournaments with different prizes. We show that if the number of agents is sufficiently small, multiple equilibria can arise. Depending on how the prize money is split over the tournaments, these may include, for example, a...

In this paper we focus on the role of caseworkers in the assignment and take-up of welfare-to-work programs. We conduct a field experiment that generates exogenous variation in the assignment to different policy regimes to caseworkers. The experiment allows us to provide evidence on the...

This paper studies mandatory job-search periods for welfare applicants. During this period the benefits application is put on hold and the applicant is obliged to make job applications. We combine a randomized experiment with detailed administrative data to investigate the effects of imposing a...

We test whether different empirical methods give different results when evaluating job-search assistance programs. Budgetary problems at the Dutch unemployment insurance (UI) administration in March 2010, caused a sharp drop in the availability of these programs. Using administrative data...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

This paper analyses data from a large-scale field experiment where unemployed workers were randomly assigned to an additional caseworker meeting with the purpose to impose a broader job search strategy. We find that the meeting significantly increases job finding and is cost effective. However,...

We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...
