Is Team Formation Gender Neutral? Evidence from Coauthorship Patterns
通过分析1991-2002年三本顶级经济学期刊的合著模式，检验团队形成是否性别中立，发现女性在子领域中的比例越高，与女性合著的性别差距越大，且女性独著比例显著高于男性，从而否定了团队形成中的性别中立性。
We model team formation as a random matching process influenced by agents ’ preferences for team size and gender composition. We then test if the coauthorship pattern in articles published during 1991–2002 in three top economics journals is gender neutral, ex-ploiting variation in female presence across subfields. Controlling for author, team, and field characteristics, we find that the gender gap in the propensity to coauthor with a woman increases in the presence of women in the subfield. We also find that women single author significantly more than men. These findings allow us to reject gender neutrality in team formation in economics. I.
