Mushfiq Mobarak and C. Austin Davis write in a Foreign Policy op-ed on how the recent Nobel prize win points to the overall potential of randomized control trials (RCTs). They cite examples of IPA's work with researchers on the topics of deworming, helping farmers time market prices in Kenya, and improving political accountability and sanitation in Bangladesh. The column also cites Chris Udry's work collecting data on investment and technology adoption in agriculture in West Africa as an example of the importance of rigorous and holistic evidence.
