In this paper, we present evidence on the effect of greater numbers of police personnel on victimisation of crime and experience of nuisance. We make use of individual data from a Dutch victimisation survey unique in its size, duration and scope. By using individual victimisation data we...

This paper investigates the question whether crime reduces investment in human capital or whether education reduces criminal activity by using fixed effect estimation on data of Australian twins. The study takes genetic and socio-economic factors shared by the twins into account. We find that...

This CPB Discussion Paper studies a conditional block grant that Dutch municipalities receive for welfare-to-work programs. Many municipalities do not fully use this grant, although programs are beneficial for them. We argue that municipalities incur expenses to use the grant. If these costs...

This paper applies the theory of auctioning incentive contracts to welfare-to-work programs. In several countries, the government procures welfare-to-work projects to employment service providers. In doing so, the government trades off adverse selection (the winning provider is not the most...

This paper examines the effects of experience rating on the inflow into disability insurance (DI) in the Netherlands, using unique longitudinal administrative data from the Dutch social benefit administration for the years 2000-2002. We follow a difference-in-differences approach to identify...

In this paper, we estimate the degree of substitution between enrolment into Disability Insurance (DI) and Unemployment Insurance (UI) in the Netherlands. Starting in the 1990s many policy measures aimed at reducing DI enrolment, and increase labour force participation. We quantify whether...

Using a simple production game, we investigate whether public firms perform better when they increase the power of their workers’ incentive schemes. In a laboratory experiment, subjects choose between a ‘public firm’ and a ‘private firm’ with team and individual incentives,...

In this paper, we construct and estimate a (semi-) structural model, so as to uncover the fraction of hidden unemployment in the Disability Insurance (DI) enrolment rate. For this purpose, we use longitudinal administrative data of Dutch employers for 1994-2003. We find the (average) fraction...

This paper analyses the relative performance and selection behaviour of not-for-profit (NFP) job training service providers, using contract data from the Dutch social benefit administration. Our analysis takes full account of selection effects, both ex ante (before the contracting process) as...

This paper estimates the longer-term effects of childhood conduct disorder on human capital accumulation and violent and criminal behaviour later in life using data of Australian twins. We measure conduct disorder with a rich set of indicators based on diagnostic criteria from psychiatry...
