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 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...

In 2003, the government will enter into performance contracts with each of the 25 regional police forces. The performance contracts establish a direct link between meeting a number of quantitative performance targets and financial incentives. A major improvement in police performance is...

This research shows that social capital is important in explaining why crime is so heterogeneous across Dutch municipalities. Social capital is considered as a latent construct composed of a variety of indicators, such as blood donations, voter turnout, voluntary contributions to community...

This study provides the first estimates of the causal effect of time in school on cognitive skills for many countries around the world, for multiple age groups and for multiple subjects. These estimates enable a comparison of the performance of education systems based on gain scores instead of...

This paper investigates the effect of obtaining an individual research grant (Vernieuwingsimpuls or IRI -grant) on the careers of Dutch scientists. <strong>The main goal of this scheme of the Dutch Research Council is to provide relatively young, talented scientists with appealing career opportunities...</strong>

Combining employment data with the British Skill Survey (BSS) –which has comparable within-occupation task data for three waves: 1997, 2001 and 2006– we analyse employment changes between occupations (extensive margin) and within occupations (intensive margin). First, we find...

This CPB Discussion Paper investigates the effect of receiving a grant from the Dutch Technology Foundation STW on the research output of an individual researcher. <strong>We find no evidence that STW grant receipt increases research output for the general funding programme (OTP) whereas the results...</strong>

This research investigates to what extent subjective teacher assessment of children’s ability adds to the use of test scores in the explanation of children’s outcomes in the transition from elementary to secondary school. This in terms of initial track allocation, track switching...

This paper investigates the effects of education vouchers for teachers. We study effects on enrollment and completion of higher education programs, and on the retention of teachers in the education sector. We do this by exploiting a fuzzy regression discontinuity design. Read also the...
