In many countries there is a deep concern about shortages of Science and Engineering workers (S&E). This article focuses on the effectiveness of policies aimed at stimulating the supply of S&E workers in the Netherlands. Despite the 'common wisdom' of severe and increasing shortages, we do not...

This paper evaluates the effects of a special program designed to increase school enrolment and employment among multi-problem youths. Treated youths are guided by personal coaches and receive a comprehensive treatment of educational, work, and health services. We investigate the impact of the...

This paper investigates the effect of coaching in vocational education on school dropout using data from a randomized experiment. We find that one year of coaching reduces school dropout by more than 40 percent from 17 to 10 percentage points. The reduction in school dropout results from two...

This paper examines the causal link that runs from classroom quality to student achievement using data on twin pairs who entered the same school but were allocated to different classrooms in an exogenous way. In particular, we apply twin fixed-effects estimation to assess the effect of teacher...
