"My research shows very strong empirical evidence that women leaders are associated with positive outcomes for women executives in substantive and important ways," said Professor Bell. "It seems a logical conclusion to infer that women leaders help the women below them. If equity for high-skilled and performing women is a policy goal, then the one obvious instrument is affirmative action at the very top of the corporate hierarchy."

Professor Bell's study merges the Standard & Poor's ExecuComp data for the years 1992-2003 with an independent data set from the Institutional Investor Research Center (IIRC) on Corporate Directors. Firms in the ExecuComp data constitute more than 80% of the total market capitalization of U.S. public companies. The data contains information on compensation and the individual components of compensation of the top five executives of all firms in the S&P 500, S&P Midcap 400, and S&P Smallcap 600. There are 25,529 unique executive observations and 2,194 unique firm observations over the 12-year period.

Professor Bell's research extends the work on the gender pay gap in top executive jobs in several ways. First, she studied the executive gender gap through 2003, thereby extending analysis to a period of greater participation of women executives generally and specifically at higher ranks. Second, because of the large sample size of firms and the tripled representation of women at high levels in later years, Professor Bell was able to test empirically the impact of women leaders on the careers of other executive women.
