This has probably been my favourite audiobook so far (and the competition has been strong!). Banerjee and Duflo survey attempts to help the global poor through nutrition, education, microfinance, and more. Their conclusions can be summarised as: details matter. Interventions that have intuitive appeal may not work on the ground, and in interventions that work on the ground in one region may not work in another.
I was worried that listening to this in audiobook form rather than reading it would be difficult, given that economics is bound to be quite detailed and involve graphs. This didn’t end up being an issue, though. Highly recommended!
