Gender bias in team formation: the case of the European Science Foundation’s grants

Abstract This paper investigates gender bias (if any) when teams are formed. We use data from the European Science Foundation to estimate if female scientists have the same opportunities as their male colleagues to join a team when applying for funds. To assess gender bias, we construct a control group of scientists with the competencies for being invited to join the team but who do not join. By comparing the proportion of female scientists in the control group with the one in the observed teams, we find a gender bias against female scientists. Exploring heterogeneity across teams, we find that gender bias is less pronounced in teams led by women, junior scientists, and in more recently formed teams. We also observe differences across disciplines.
