Two Danish researchers looked into the reasons why certain men are more generous than others. They looked at the wages male chief executives paid their staff over the course of 10 years and the conclusions were quite astonishing. On average, they paid their employees less, once they became fathers, but only if it was a son. The wages did not change if their newborn was a girl.
Various other studies have shown that baby girls tend to make their fathers more generous, but also, when men have grown up with siblings and even more so if there were sisters amongst them.
Other studies lead to the conclusion that top managements need more women as it has been proven that when companies include women in their top management, they generated an average of 1% more economic value.
