The parenthood gap: Firms and earnings inequality after kids

We document the dynamics of career paths around parenthood, capturing worker advancement within firms and across firms with differing pay rates. Using a new linkage between administrative data on U.S. workers' fertility and labor market histories, we show that the parental earnings gap is partly explained by mothers transitioning to lower-paying firms. Firm downgrading is driven by parents who take an extended absence from the labor force. Mothers who move to lower-paying firms see improved job amenities but less generous fringe benefits. The firm's contribution to the parental earnings gap rises over time and reaches one-third by the child's 11th birthday.
