摘要

我们估计了一种教育同伴干预的效果，在这种干预中，以前成绩好的和成绩差的学生被随机配对为中国小学的同桌。我们的治疗方法提高了成绩差的学生的数学成绩。此外，治疗增强了优等生和低等生的外向性和亲和性，从而提供了同伴影响人格特质的证据。积极的治疗效果可归因于同桌水平的同伴效应。我们记录了朋友网络结构的变化，并提供了更多的证据，证明友谊关系如何帮助我们更好地理解同伴效应背后的机制。(j21, i26, j24, o15, p36, z13)

Student Performance, Peer Effects, and Friend Networks: Evidence from a Randomized Peer Intervention

We estimate the effects of an educational peer intervention in which previously high- and low-achieving students are randomly paired as deskmates in elementary schools in China. Our treatment boosts the mathematics scores of the low-achieving students. Moreover, the treatment enhances the extraversion and agreeableness of high- and low-achieving students, thereby providing evidence that peers can influence personality traits. The positive treatment effects can be attributed to the deskmate-level peer effects. We document friend network structure changes and present additional evidence on how friendship ties help us better understand the mechanisms behind peer effects. (JEL I21, I26, J24, O15, P36, Z13)
