From Harvard Business Review authored by Erin Reid:
“An economic mystery of the last few decades has been why more women aren’t working. A new paper offers one answer: Most plan to, but are increasingly caught off guard by the time and effort it takes to raise children.
The share of women in the United States labor force has leveled off since the 1990s, after steadily climbing for half a century. Today, the share of women age 25 to 54 who work is about the same as it was in 1995, even though in the intervening decades, women have been earning more college degrees than men, entering jobs previously closed to them and delaying marriage and childbirth.
The new analysis suggests something else also began happening during the 1990s: Motherhood became more demanding. Parents now spend more time and money on child care. They feel more pressure to breast-feed, to do enriching activities with their children and to provide close supervision.
A result is that women underestimate the costs of motherhood. The mismatch is biggest for those with college degrees, who invest in an education and expect to maintain a career, wrote the authors, Ilyana Kuziemko and Jenny Shen of Princeton, Jessica Pan of the National University of Singapore and Ebonya Washington of Yale.”
