JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 240 OP 277 DO 10.3368/jhr.55.1.0416-7839R1 VO 55 IS 1 A1 Davezies, Laurent A1 Garrouste, Manon YR 2020 UL http://jhr.uwpress.org/content/55/1/240.abstract AB By analyzing a French program that targeted low-achieving and socially disadvantaged junior high schools we provide evidence that school-based compensatory education policies create sorting effects. We use geocoded original data and a regression discontinuity framework to show that the program decreases the individual probability of attending a treated school and symmetrically increases the probability of attending a private school. The effects are driven by pupils from high socioeconomic backgrounds, resulting in an increase in social segregation across schools.
