Duflo, a French development economist, is a champion of randomized field experiments to test how well poverty-fighting programs are working. She helped launch JPAL, which measures
things like whether reducing class size helps kids learn better in Kenya (it doesn't) or whether having teachers photograph themselves at school every day reduces teacher
absenteeism in India (it does). Duflo won a MacArthur grant in 2009 and this year was awarded the John Bates Clark Medal, often a precursor to a Nobel Prize.
