Esther Duflo discusses her work on the economics of poverty, for which she won this year's Nobel prize, along with her husband Abhijit Banerjee and co-author Michael Kremer.

The 46-year old French-American MIT economist is the youngest person ever to be awarded the prize, and only the second woman. Ed Butler asks her how she and her collaborators examined how people in poverty respond differently to economic incentives, and her views on how her profession could benefit from being less male-dominated.
