Are substitute services a barrier to controlling long-term care expenditures?
The scope of the external return to higher education
This article examines whether the productivity spillovers from a large share of highly educated workers occur within regions, sectors and/or firms. To distinguish between these possibilities, I follow a two-stage procedure to estimate a Mincerian wage equation using matched employer-employee panel data on individual earnings and educational attainment. →

Economic Decision Problems in Multi-Level Flood Prevention: a new graph-based approach used for real world applications
Flood prevention policy is of crucial importance to the Netherlands. We assess economical optimal flood prevention where multiple barrier dams and dikes protect the hinterland against sea level rise and peak river discharges. Current optimal flood prevention methods only consider dike rings with no dependencies between dikes. We propose a graph-based model for a cost-benefit analysis to determine optimal dike heights with multiple dependencies between dikes and barrier dams. →
Does managed competition constrain hospitals’ contract prices? Evidence from the Netherlands
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. →

Optimal Taxation of Secondary Earners in the Netherlands: Has Equity Lost Ground?
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. →
Do paid teacher trainee programs lead to additional teachers in secondary education? A Regression Discontinuity Analysis
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. →
