RT Journal Article SR Electronic T1 The Impact of Teacher-Student Gender Matches: Random Assignment Evidence from South Korea JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1215-7585R1 DO 10.3368/jhr.52.4.1215-7585R1 A1 Lim, Jaegeum A1 Meer, Jonathan YR 2017 UL http://jhr.uwpress.org/content/early/2017/02/01/jhr.52.4.1215-7585R1.abstract AB Gender disparities in academic performance may be driven in part by the interaction of teacher and student gender, but systematic sorting of students into classrooms makes it difficult to identify causal effects. We use the random assignment of students to Korean middle school classrooms and show that the female students perform substantially better on standardized tests when assigned to female teachers; there is little effect on male students. We find evidence that teacher behavior drives the increase in female students’ achievement.
