Using a matched event study design, we trace monthly changes in determinants of wages (job performance, human capital accumulation, and promotions). Data come from a usefully unusual setting with required multiyear employment and detailed personnel data: the U.S. Marine Corps. Mothers\u2019 job performance initially declines, and gaps in promotion grow through 24 months postbirth. Fathers\u2019 physical fitness performance drops somewhat but recovers. These patterns lead mothers to earn relatively lower wages, even absent changes in employment postbirth.<\/p>\n<\/div>\n<\/div>\n<div class=\"full-bg-sand full-bg-bottom\">\n<div class=\"sans small\">\n<p>This publication is part of the RAND external publication series.
