This paper studies the effect of same-sex teachers on students attending Economics A at Uppsala University from 2013 to 2018. Having a female teacher has no significant effect on female students’ exam performance but a significant and positive effect on the likelihood of attending the subsequent course in Economics. Certain types of female teachers have negative effects on male students’ exam performance in certain specifications and no effect on the likelihood of them attending the subsequent course. It was not possible to identify the underlying mechanism behind these results.
