Alice Korngold writes about the importance of investing in girls for major economic growth in developing countries in this Sept. 14, 2011 post from Fast Company:

In its newly released report, “Measuring the Economic Gain of Investing in Girls: The Girl Effect Dividend,” The World Bank calculates the positive economic impact for fourteen developing countries if interventions reverse the patterns of early school dropout, teenage pregnancies, and joblessness for girls.
