Title: Girls Help Girls, but Boys Gain Little: Exploring the Mechanisms of Gender Peer Effects in Elementary Schools

要旨/Abstract: I estimate the effect of peer gender composition on elementary school students’ test scores and examine the underlying mechanisms using data from Saitama Prefecture, Japan. Exploiting within-school and across-cohort variation in gender composition, I show that a higher female ratio increases girls’ test scores but does not affect boys’ test scores. I propose a decomposition method to mitigate spurious correlations and suggest that the null effect on boys’ test scores reflects two offsetting forces: a positive effect from an improved learning environment and a negative effect from reduced study engagement.
