Title: Outside Job Opportunities and the Gender Gap in Pay

Abstract: A growing literature suggests that outside job offers are an important component of on-the-job wage growth. Such outside offers could contribute to the gender wage gap due to a differential arrival rate of (relevant) job opportunities and/or because of gender differences in negotiation. In this paper, we shed light on this source of gender wage inequality by empirically studying male and female wage and job mobility responses to the arrival of outside job opportunities that arise via family networks. We show in Swedish register data that such opportunities are associated with higher wages for men but not for women. However, women have higher job mobility in response to expansions in connected firms- particularly when those offer a shorter commute compared to the current employer. Together, our results are consistent with women being less likely to renegotiate in response to the arrival of job offers. The paper thus confirms in a broader setting that gender negotiation differences is an economically meaningful source of the remaining gender pay gap.
