Abhijit Banerjee, Esther Duflo and Michael Kremer have been jointly awarded the Nobel Prize in economics for their experimental approach to alleviating global poverty.
Mr Banerjee and Ms Duflo — a couple both at work and in their private life — are professors at the Massachusetts Institute of Technology, while Mr Kremer is a professor at Harvard University.
Ms Duflo, 46, becomes only the second woman to be awarded an economics Nobel, after the US economist Elinor Ostrom who won the prize in 2009 for her work on human co-operation. She is also the youngest-ever laureate in economics: the previous record was held by Kenneth Arrow, who was 51 when he was awarded the prize in 1972.
