RT Journal Article SR Electronic T1 Understanding Gender Match Effects in Higher Education JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0224-13406R1 DO 10.3368/jhr.0224-13406R1 A1 Maurer, Stephan A1 Schwerdt, Guido A1 Wiederhold, Simon YR 2026 UL http://jhr.uwpress.org/content/early/2026/04/01/jhr.0224-13406R1.abstract AB It is widely believed that female students perform better when taught by female professors. However, little is known about the mechanisms explaining these gender match effects. Using administrative records from a German public university, which cover all programs and courses between 2006 and 2018, we show that gender match effects are sizable in smaller classes, but are absent in larger classes. These results suggest that direct and frequent interactions between students and professors are crucial for gender match effects to emerge. In contrast, the mere fact that one’s professor is female is not sufficient to increase performance of female students.
