On Monday, Abhijit Banerjee, 58, and Esther Duflo, 46, won the Nobel Prize in Economics, along with economist Michael Kremer, for their "experimental approach to alleviating global poverty". More than 700 million people live in extreme poverty, according to World Bank.
Both Mr Banerjee and Ms Duflo are professors at the Massachusetts Institute of Technology (MIT). Ms Duflo is the second woman to be awarded a Nobel in economics.
The Indian-born Mr Banerjee and Paris-born Ms Duflo grew up in completely different worlds.
