Does preschool boost the development of minority children? The case of Roma children

Does universal preschool constitute an effective policy tool to promote the development and integration of children from minority groups? In the light of rising cross border migration and increasing ethnic variation in many developed countries, we address this question for the children of the Roma - the largest and most disadvantaged minority in Europe. To tackle the issue of non-random selection into preschool, we exploit variation in the individual distance to the nearest preschool facility. Non-parametric instrumental variable estimations reveal significant short-term gains in terms of children's verbal and analytical skills. Preschool attendance also increases the prevalence of vaccinations, but has no effect on other health outcomes. Overall, it also does not seem to enhance integration measured by language proficiency and peer relations, at least not in the short-run.
