"The facts couldn't be clearer: smart women equal stronger companies."

Research conducted by both Catalyst and McKinsey & Company demonstrates that companies with significant numbers of women in management have a much higher return on investment. In addition, a recent study from London Business School shows that when work teams are split 50-50 between men and women, productivity goes up. 

My favorite study, published last October by CERAM Business School, showed that firms in the CAC 40 (the French equivalent of the Dow Jones Industrial Average) with a high ratio of women in top management showed better resistance to the financial crisis. The fewer female managers a company has, the greater drop in its share price since January 2008.
