In academia, some studies have shown than mandatory paternity leave may not close gaps in productivity: The authors compared promotion rates before and after these gender-neutral parental policies were adopted, relative to trends in comparable institutions that did not alter their policies, while also accounting for an array of influences, like where each economist was trained. They found that men who took parental leave used the extra year to publish their research, amassing impressive publication records. But there was no parallel rise in the output of female economists.
