<p>This paper investigates the gender pay gap among employed students. Using four waves of a large-scale French tertiary education student survey, I find that female students earn on average 7.8% less per hour than male students, a gap that narrows to 3.3% once a rich set of observable characteristics is taken into account. Differences in field of study, higher education track, and student job allocation account for the largest share of the explained gap. Women are disproportionately concentrated in lower-paid jobs that are unrelated to their field of study, most notably babysitting and employment in retail and hospitality. Correcting for non-random selection into paid employment leaves the estimated gender pay gap largely unchanged. I further find that women are more likely to be employed during their studies, a pattern that is not driven by stronger financial constraints or lower academic investment. Instead, I provide suggestive evidence for gender differences in motives for paid work, with women more likely than men to report working in order to gain independence from their parents. Finally, exposure to non-traditional family roles appears to matter: women whose mothers are employed, and especially those whose mothers are the primary breadwinner, are substantially more likely to work during their studies.</p>
