#280: Poor Economics

There's a lot of hand waving in economics. People make big-picture arguments and throw around equations, but often there's not much good evidence to work with.MIT economists Abhijit Banerjee and Esther Duflo do experiments to try to figure out how to improve the lot of the world's poor. Their goal isn't so much to make big, sweeping statements as to find clear answers to specific questions.On today's Planet Money, we talk to Banerjee and Duflo about their new book, Poor Economics.
