According to a study by the Peterson Institute for International Economics and EY, having women in top management positions leads to an increase in profits:
The study found that female C.E.O.s did not significantly underperform or overperform when compared with male chief executives. While it found some indications that having more women on boards was correlated with higher profitability, Marcus Noland, the institute’s director of studies, said that “in statistical terms that evidence is not robust.”
But the data was clear about women in top management positions. An increase in the share of women from zero to 30 percent would be associated with a 15 percent rise in profitability, Mr. Noland said.
