Héloïse CLOLERY (Bocconi) – “The Effects of Quotas on Team Decisions: Prior Biases and Learning”

CV : This paper investigates how affirmative action quotas influence team decision-making through belief updating and confidence. While quotas increase diversity, they also create uncertainty about the role of merit versus demographics in selection. As a result, success conveys less information about candidates’ relative abilities within a team when there is a quota. Yet, little is known about how such uncertainty influences participants’ confidence and team dynamics.
In a laboratory experiment, teams with a quota achieved, on average, 2 points higher scores on a 0–10 scale compared to teams without a quota, once controlling for any composition effect. While quotas do not differentially affect individual contributions by gender, they generate a gender gap in the confidence signals conveyed during interaction. When including the negative selection effect of the quota, I do not obtain a negative effect of quotas on team performance. This is due to women becoming less confident and contributing relatively less than men when advantaged by a quota.
