"A year of delayed motherhood is found to increase career earnings by 9 percent, work experience by 9 percent, and average wage rates by 3 percent," so says a study just published by Journal of Population Economics.
The study, "The Effects of Motherhood Timing on Career Path," was written by Amalia R. Miller, an economics professor at the University of Virginia. The study also notes how the effects of delay are amplified by greater amounts of education.
"Supporting a human capital story, the postponement premium is largest for college-educated women and those in professional and managerial occupations. Family leave laws do not significantly influence the premium," the study notes.
