【 摘 要 】

This paper provides experimentalevidence of the effect of having peers with differentpropensities for violence in the context of an afterschoolprogram. By randomly assigning students to participate inthe program with a set of similar or diverse peers in termsof violence, the study measures the effects of segregationor integration on students' behavioral,neurophysiological, and academic outcomes. The paper alsoexploits a discontinuity around the median of the propensityfor violence distribution, to measure the impacts ofsegregation on marginal students. The results indicate thatintegrating students with different propensities forviolence is better for highly and less violent children thansegregating them. In particular, the intervention can haveunintended effects on misbehavior and stress, if highlyviolent students are segregated and treated separately fromtheir less violent peers.
