American individuals and institutions spent billions of dollars to ease global poverty and accomplished almost nothing. At last we have a realistic way forward. Presenting innovative and successful development interventions around the globe, Dean Karlan and Jacob Appel show how empirical analysis coupled with the latest thinking in behavioral economics can make a profound difference.
