Is there a business case for diversity? My gosh, it’s overwhelming. I know you’ve heard the opposite. Supposedly, the business case for diversity is weak at best.

HAVING WOMEN AT THE TOP PAYS

A number of recent business studies, including a research report in Catalyst Inc. in 2011 by Nancy M. Carter and Harvey M. Wagner titled “The Bottom Line: Corporate Performance and Women’s Representation on Boards (2004-2008),” looked at the financial returns of companies with three or more women on the board.
