To reach these conclusions, [Vanderbilt law and economics professor Joni] Hersch gathered data from the 2003 National Survey of College Graduates, which provided information on 100,000 grads from the full spectrum of four-year colleges and universities. She says she chose to use the 2003 report because it was the most comprehensive. ...
The pay differences alone make Hersch’s findings surprising. “For those working full-time, the average salaries [of grads from elite MBA programs] are nearly double that of the other groups,” she says. “In 2003 dollars it’s around $137,000, vs. around $74,000 for the other tiers.”
Considering that women from elite schools are the ones who are most likely to land senior management roles, this could begin to explain why fewer women are gaining access to the C-suite, Hersch says. If they stop working, they can never reach those positions, and the women from lesser-recognized schools rarely get the same opportunities for advancement.
