Christine Lagarde (No. 9), France's former finance minister, for example, is now managing director of the I.M.F., and Ngozi Okonjo-Iweala (No. 87) switched from the World Bank to finance minister of Nigeria. Susan Wojcicki (No. 16) was upped to SVP at Google and Denise Morrison (No. 80) was promoted from COO to CEO for Campbell Soup. She's one of 29 CEOs here. Dilma Rousseff (No. 3) and Yingluck Sinawatra (No. 59) were elected as president of Brazil and prime minister of Thailand, respectively, now in a club of eight heads of state on the list.

We looked at if they hold sway over multiple spheres of influence rather than have a single source of authority.
