The pioneering work of economists Abhijit Banerjee, Esther Duflo, and Michael Kremer, for which they were awarded the Nobel Prize in Economics in 2019, has been instrumental in popularizing the use of RCTs in development economics.

By comparing outcomes between the two groups, researchers can isolate the program's causal effect. This methodology has been applied in hundreds of studies across dozens of countries, generating reliable evidence on what works in areas like education, health, agriculture, and finance.
