I found this quite interesting:
A new, not-yet-published study that tracked 12 years of wage data in Denmark finds that when male CEOs had daughters, their female employees’ wages went up 1.3 percent while their male employees only gained .8 percent raises. So the birth of a daughter effectively shrunk the male-female wage gap by .5 percent on average.
If the daughter was a first child, the gap closed by a whopping 2.8%!
The rest of the article: After CEOs have daughters, women employees’ wages go up
Now I’m awfully curious about whether this holds specifically for the tech industry, and what the birth rates for CEOs are… but it sounds like it’s sufficiently difficult to get data that we may never see that study.
