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 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 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 introduces indicators about the division of labour to measure and interpret recent trends in employment in the Netherlands. We show that changes in the division of labour occur at three different levels: the level of the individual worker, the level of the industry and the spatial...

Based on micro-data on individual workers for the period 2000–2005, we show that regional wage differentials in the Netherlands are small but present. A large part of these differentials can be attributed to individual characteristics of workers. Remaining effects are partially...

This research documents the effects of different forms of family disruptions - measured by separation, divorce and death - on personality development of British children included in the 1970 British Cohort Study. There are statistically significant correlations between family disruptions prior...

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...
