Abstract
Despite the shrinking of the gender wage gap, women with children continue to experience earnings and career disadvantages that women without children do not experience. This review first summarizes how the severity of the "motherhood penalty" is influenced by a woman's marital status and class in ways that perpetuate existing inequalities. Next, it outlines how the same factors also play salient roles in determining women's workforce behaviors upon transitioning to motherhood, largely dictating the extent to which women's earnings and careers are negatively impacted by the arrival of children. After establishing the stratified lines upon which mothers' decisions are made, and the disparate financial ramifications of their decisions, the paper concludes with a call for future research into the mechanisms that propel mothers' labor market decisions.
