In Vox, an open letter to Bill Gates
PI Chris Blattman published an open letter to Bill Gates in Vox.com, citing several IPA studies. Gates has a plan to boost chicken ownership in sub-Saharan Africa from five to 30 percent. But we know from rigorous randomized controlled trials that cash is cheap, effective, and easy to deliver. Blattman urges Gates to promote a randomized controlled trial to determine which is the most effective and efficient way to help the poor.
