Interesting. But I wonder who the non-negotiating women are. This group did an experiment where they told volunteers that they'd be paid $3-10 to play a game of boggle. When offered $3 once the game was done, far more women than men took the low offer rather than asking for more. Maybe they've accidentally selected for women who have outside situations that decrease their money drive.

Negotiation stories are interesting. But I've also heard anecdotal stories about newly hired assistant professors pushing hard for better offers and then getting low-balled on raises for a few years until they're more on par with their peers. Have you ever seen any data on whether playing hardball with starting salary really gets people to substantially higher salaries 5 or 10 years in?
