Women in economics: Esther Duflo, randomised control trials (RCTs)

Co-founder and co-director of the Abdul Latif Jameel Poverty Action Lab, Esther Duflo, has worked extensively on reducing poverty and increasing immunisation in countries like India and Africa. Here she speaks about the use of randomised controlled trials (RCTs) which revealed that improving the supply of immunisations in India was one factor that increased uptake, but this could be substantially amplified by a little extra outlay on small incentives for people to have their children vaccinated.
