Using data from the Judicial Yellow Book and a database of federal court cases, the researchers find that judges who hear more cases alongside female colleagues are 4 percentage points more likely to hire at least one female law clerk in the following year. They also examine whether exposure differentially affects judges who vary in meaningful ways — by gender, age, experience level, political affiliation, status, quality, and current law clerk staff composition. The effects of exposure to female judicial colleagues are larger for men, for judges whose current roster of law clerks is majority male, and for less-experienced judges. For example, male judges who hear more cases alongside female judges are 4.3 percentage points more likely to hire a female law clerk subsequently, while female judges who hear more cases alongside female judges are 1.6 percentage points more likely to hire a female law clerk subsequently.
We find that the proportion of female hires increases by 1.93% if you replace a son with a daughter for the existing partners in a firm. Given that about 8.03% of the new hires are female, this suggests a 24% increase in the probability of hiring a senior female investor when a son is replaced with a daughter for the existing partners. … [W]e also show that improved gender diversity, induced by parenting more daughters, improves deal and fund performances.
My guess is that not many judges or venture capitalists had previously been openly vowing not to hire women as clerks or as as part of venture capital firms; indeed, I\’m sure many of had previous hired a few women. In addition, I doubt that these changes involved an open and conscious change-of-heart epiphany about hiring more women. I doubt that a lot of judges were muttering in their chamber: \”Well, now that I\’ve been on a panel with a female judge, I\’ll go ahead and hire more female law clerks.\” I doubt a lot of venture capitalists were muttering to themselves: \”Well, now that I have a daughter, all of a sudden women job applicants seem more plausible to me.\” Instead, it seems to me that these kinds of studies both demonstrate the existence of an unconscious bias and a mechanism for attenuating that bias.
[P]olicies to increase interracial contact—like limiting residential segregation—may offer a useful point of leverage. Residential and social segregation may lead to prejudice and taste-based discrimination. Pettigrew and Tropp (2006) provide a meta-analysis of 515 studies and conclude that there is strong support for “intergroup contact theory,” which proposes that contact tends to reduce prejudice. Some economists have contributed to our understanding of this topic. Carrell, Hoekstra, and West (2015), for example, found that having an additional black member in an Air Force squadron of roughly 35 people increased the probability of having a black roommate as a sophomore (usually not a freshman squadron member) by about one percentage point, or about 18 percent. Similarly, exposure to more black peers with high admissions scores increased the probability that whites reported that they had become more accepting of African Americans. Dahl, Kotsadam, and Rooth (2018) find similar positive effects on male attitudes towards female recruits from having been assigned to a squad with a woman member during boot camp in Norway. In particular, given the importance of networks in job search, social distance can directly increase racial disparities in employment (Loury 2000). These studies, together with the large literature outside economics, suggest a public interest in greater integration and reducing social distance across groups.
