We study the effect of a policy change in co-payments on the use of long-term home care in The Netherlands. The change increased co-payments for persons with considerable household financial assets. For identification we apply a difference-in-difference analysis with matched treatment and control groups. →

In health care systems with a competitive health insurance market, governments or other sponsors (e.g. employers) often subsidize premiums to encourage enrolment. These subsidies are typically independent of plan choice leaving the absolute premium differences in place so as not to distort consumer choice of plan. →

We study the impact of a mandatory activation program for young welfare recipients in the Netherlands. Introduced at the end of 2009, the goal of the program was to prevent so-called NEETs (individuals not in employment, education or training). →

This analysis is based on the measures in the financial appendix to the Coalition Agreement, as submitted to CPB on 29 September. Chapter 10 lists the measures included in the analysis. →

In CBA practices around the world, benefits are valued regardless of to whom they accrue. This disregards basic economic principles, like declining marginal utility of income, or inequality aversion. This paper argues that if redistribution matters, net benefits must be aggregated using a distributionally weighted CBA. →

The rise of online trade alters the role of distance between (potential) buyers and sellers. We use data from eBay subsidiary Marktplaats.nl, one of the largest online trading platforms in the Netherlands, to estimate how distance affects the probability of a transaction between small geographical regions. →

The Netherlands witnessed major reforms in income support for lone parents over the past decade. The goals of these reforms were to improve the financial incentives to work and to simplify the system. We consider whether the new system can be considered (closer to) `optimal'. →

In this paper, I present a new toolbox that implements the exact nonlinear and non-Gaussian Kalman smoother for a wide class of discrete-time state space models, including models with implicit functions and equality constraints. →

In this paper, I present a novel implementation of the exact nonlinear and non-Gaussian Kalman smoother that can also deal with implicit functions in the measurement and/or state equations as well as equality constraints. →

The circular economy aims to reduce the use of raw materials, promote re-use and recycling and limit waste. This study focuses on the circular economy of plastics and investigates what the major problems are in relation to the use of plastics and to what extent government policy is necessary and effective. →
