RT Journal Article SR Electronic T1 The Motherhood Earnings Dip: Evidence from Administrative Records JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 169 OP 197 DO 10.3368/jhr.48.1.169 VO 48 IS 1 A1 Daniel, Fernández-Kranz A1 Lacuesta, Aitor A1 Rodríguez-Planas, Núria YR 2013 UL http://jhr.uwpress.org/content/48/1/169.abstract AB Using Spanish Social Security records, we document the channels through which mothers fall onto a lower earnings track, such as shifting into part-time work, accumulating lower experience, or transitioning to lower-paying jobs, and are able to explain 71 percent of the unconditional individual fixed-effects motherhood wage gap. The earnings trajectories' analysis reveals that “mothers to be” experience important relative earnings increases several years before giving birth but this earnings' advantage falls right after birth, taking in average nine years to recover. Heterogeneity matters as most of the motherhood dip is driven by workers with permanent contracts.
