The 2019 Nobel Prize in Economic Sciences has been awarded jointly to Abhijit Banerjee, Esther Duflo, and Michael Kremer “for their experimental approach to alleviating global poverty”. This column outlines their impact on development economics research and practical action to reduce poverty. It also considers some of the critiques of randomised controlled trials as an approach to development.

Entrepreneurs often predict future revenues using rules of thumb. The column argues that by testing precise hypotheses, 'scientist-entrepreneurs' would be less likely to invest in failures. A randomised controlled trial among Italian start-ups showed that this technique increased average returns for entrepreneurs. Used more generally, the precision effect may help screen out bad business ideas at an early stage.
