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...

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...

We study how job seekers respond to wage announcements by assigning wages randomly to pairs of otherwise similar vacancies in a large number of professions. High wage vacancies attract more interest, in contrast with much of the evidence based on observational data. Some applicants only show...

We develop and evaluate experimentally a novel tool that redesigns the job search process by providing tailored advice at low cost. We invited job seekers to our computer facilities for 12 consecutive weekly sessions to search for real jobs on our web interface. For half, instead of relying on...

We propose a simple method for eliciting individual time preferences without estimating utility functions even in settings where background consumption changes over time. It relies on lottery tickets with high rewards. In a standard intertemporal choice model high rewards decouple lottery...

While a large share of Disability Insurance recipients are expected to recover, outflow rates from temporary disability schemes are typically negligible. We estimate the disincentive effects of disability benefits on the response to a (mental) health improvement using administrative data on all...

In a randomized field experiment, we provide personalized suggestions about suitable alternative occupations to long-term unemployed job seekers in the UK. The suggestions are automatically generated, integrated in an online job search platform, and fed into actual search queries. Effects on the...

This paper examines to what extent an income tax exemption affects international mobility and wages of skilled immigrants. We study a preferential tax scheme for foreigners in the Netherlands, which introduced an income threshold for eligibility in 2012 and covers a large share of the migrant...

Workers with fixed-term contracts typically have worse health than workers with permanent contracts. We show that these differences in health translate into a substantially higher (30%) risk of applying for disability insurance (DI) in the Netherlands. Using unique administrative data on health...
