Can Gender Parity Break the Glass Ceiling? Evidence from a Repeated Randomized Experiment
利用西班牙司法考试中评委随机分配的自然实验，发现女性占多数的评委会高估男性候选人质量，导致女性候选人更难被录用。
This paper studies whether the gender composition of recruiting committees matters. We make use of the unique evidence provided by Spanish public examinations, where the allocation of candidates to evaluating committees is random. We analyse how the chances of success of 150,000 female and male candidates for positions in the four main Corps of the Spanish Judiciary from 1987 to 2007 were affected by the gender composition of their evaluation committee. We find that a female (male) candidate is significantly less likely to be hired whenever she (he) is randomly assigned to a committee where the share of female (male) evaluators is relatively greater. Evidence from multiple choice tests suggests that this is due to the fact that female majority committees overestimate the quality of male candidates.
