Esther Duflo won 2019's Nobel prize for economics with her partner Abhijit Banerjee and Michael Kremer. Together they've written a new book called 'Good Economics for Hard Times' which seeks to answer some of the world's biggest social and political questions. A resident professor at MIT, Esther talks to Krishnan about what it's like to win the prize, why low-skilled migration is not an economic threat and why she pushes evidence not ideology.
