RT Journal Article SR Electronic T1 More Harm than Good? Sorting Effects in a Compensatory Education Program JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0416-7839R1 DO 10.3368/jhr.55.1.0416-7839R1 A1 Davezies, Laurent A1 Garrouste, Manon YR 2018 UL http://jhr.uwpress.org/content/early/2018/07/03/jhr.55.1.0416-7839R1.abstract AB We provide evidence that school-based compensatory education policies create sorting effects, by analyzing a French program, which targeted low-achieving and socially disadvantaged junior high schools. We use geocoded original data and a regression discontinuity framework to show that the program decreases the individual probability to attend a treated school and symmetrically increases the probability to attend a private school. The effects are driven by pupils from high socioeconomic backgrounds, resulting in an increase in social segregation across schools.
