The market for higher education increasingly becomes an international market. Nowadays, the number of students studying abroad is substantial and increasing. Many governments stimulate students to study abroad by offering a wide range of grants. However, little is known on the returns to...

Recently, there has been considerable debate about a reform of the Dutch system of student support, in which grants will be (partly) replaced by loans. The discussion focuses on the effects on student enrollment decisions. Surprisingly, no study has yet analysed the effect of receiving a grant...

We analyse the causal effect of education on starting and quitting smoking, using longitudinal data of Australian twins. We take into account the endogeneity of education, censoring of smoking durations and the timing of starting smoking versus that of completing education by using the flexible...

A shortage of teachers in primary and secondary schools in the Netherlands is expected in the near future as a large part of the current workforce will retire. Recently, the Dutch government has decided to increase wages of teachers. This paper qualitatively assesses the impact of three...

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...

Inspectors from the Dutch Inspectorate of Education inspect primary schools, write inspection reports on each inspected school, and make recommendations as to how each school can improve. We test whether these inspections result in better school performance. Using a fixed-effects model, we...

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...

This paper analyses the causal effect of education on the probability of being overweight by using longitudinal data of Australian identical twins. The data include self-reported and clinical measures of body size. The prevalence of overweight and obesity is growing rapidly in many countries....

In 1982, duration of university education in the Netherlands decreased from five to four years. This institutional reform is exploited for estimating the causal effect of one year of university education on wages in 1997. Wages of employees who enrolled just before or after the reform are...
