About 10 years ago, a group of graduate students lodged a complaint with Linda C. Babcock, a professor of economics at Carnegie Mellon University : All their male counterparts in the university’s PhD program were teaching courses on their own, whereas the women were working only as teaching assistants.
That mattered, because doctoral students who teach their own classes get more experience and look better prepared when it comes time to go on the job market.
When Babcock took the complaint to her boss, she learned there was a very simple explanation: “The dean said each of the guys had come to him and said, ‘I want to teach a course,’ and none of the women had done that,” she said. “The female students had expected someone to send around an e-mail saying, ‘Who wants to teach?’ ” The incident prompted Babcock to start systematically studying gender differences when it comes to asking for pay raises, resources or promotions. And what she found was that men and women are indeed often different when it comes to opening negotiations.
These differences, Babcock and other researchers have concluded, may partially explain the persistent gender gap in salaries, as well as other disparities in how people rise to the top of organizations.

The traditional explanation for the gender differences that Babcock found is that men are simply more aggressive than women, perhaps because of a combination of genetics and upbringing. The solution to gender disparities, this school of thought suggests, is to train women to be more assertive and to ask for more.
