TY - JOUR T1 - The Effect of Immigration on Natives’ School Performance: Does Length of Stay in the Host Country Matter? JF - Journal of Human Resources JO - J Hum Resour DO - 10.3368/jhr.55.3.1017-9151R2 SP - 1017-9151R2 AU - Laurent Bossavie Y1 - 2018/09/05 UR - http://jhr.uwpress.org/content/early/2018/09/04/jhr.55.3.1017-9151R2.abstract N2 - This paper investigates the effects of immigrant concentration in the classroom on natives’ scholastic achievement. It utilizes rare information on age at migration to estimate separate spillover effects by duration of stay of immigrant classmates, and uses cohort-by-cohort changes in immigrant concentration within schools to identify treatment effects. The presence of immigrant students who have been in the country for some time is found to have no effect on natives. However, a small negative effect of recent immigrants on natives’ language scores is reported. When significant, effect sizes are quite small compared to other educational interventions and peer effect estimates. ER -
