We study the effect of hearing cases alongside female judicial colleagues on the probability that a federal judge hires a female law clerk. Federal judges are assigned to judicial panels at random and have few limitations on their choices of clerks. Using a unique dataset of federal case records merged with judicial hiring information, we find a significant effect of the fraction of copanelists who are female on a male judge’s likelihood of hiring a female clerk. This finding suggests that increases in the diversity of the upper rungs of a profession can create opportunities at the entry level.

This paper uses the universe of cellphone records from a Chinese telecommunication provider for a northern Chinese city to examine the role of information exchange in urban labor markets. We provide the first direct evidence of increased communication among referral pairs around job changes. Information provided by social contacts mitigates information asymmetry and improves labor market performance. (JEL D82, J62, O18, P23, P25, R23, Z13)
