In the Dutch health care system health insurers negotiate with hospitals about the pricing of hospital products in a managed competition framework. In this paper, we study these contract prices that became for the first time publicly available in 2016. The data show substantive price variation between hospitals for the same products, and within a hospital for the same product across insurers. →

The existence of an urban wage growth premium is a well-established empirical fact. This article challenges the conventional view that faster wage growth for urban workers is caused by human capital spillovers. →

This article argues that the spatial scope of agglomeration economies is much more complex than is often assumed in the agglomeration literature. We provide insight into this issue by analyzing panel data on individual wages with a high level of spatial detail. →

The Netherlands witnessed major reforms in the taxation of (potential) secondary earners over the past decade. Using the inverse-optimal method of optimal taxation we recover the implicit social welfare weights of single- and dual-earner couples over time. The social welfare weights are grosso modo well-behaved before the reforms. →

This paper evaluates the quantitative effects of two teacher traineeships that were implemented in the Netherlands to address shortages of fully qualified teachers in secondary education. Applying a fuzzy regression discontinuity design, we estimate the effects of being selected to participate in one of the traineeships. We find no significant local average treatment effects of being selected on the probabilities of enrolling into academic teacher training, obtaining a full teaching qualification, and on working in education, although the point estimates are positive for the first two outcome variables. →

Exploiting a rich data set on the Dutch market for assistance in daily housekeeping activities (ADHA), we find that larger providers obtain a higher price than do small providers. However, compared to other studies on market power in care markets this price difference is considered small to moderate. →

In this paper we investigate whether the targeted longer-term refinancing operations (TLTRO) and the asset purchase program (APP) led to lower interest rates on new corporate credit, and whether the signalling channel and the capital relief channel played any role in the transmission of these ECB policies. →

How effective are unconventional monetary policies? Through which mechanisms do they work? This discussion paper contains a detailed presentation of the new scientific evidence we reported in the policy brief, and adds to the relatively scarce literature in this field. →

According to economic theory, taxation drives a wedge between private and public benefits, which distorts labour supply, consumption and investment and leads to loss of welfare. →

According to the Melitz (2003) model, potential exporters have to be sufficiently productive to overcome the entry costs of foreign markets. Once firms pass this productivity threshold, they all export. However, empirical evidence indicates that a substantial share of high-productive firms do not export. →
