To scale effectively, you have to test effectively. Researchers @angrist_noam, @ccullen_1, and @janica_magat used iterative A/B testing to study a tutoring program in Botswana 🇧🇼 and found that overall costs were reduced by up to 11% and learning outcomes improved by 30% in some

🚨Happy this is out in the world! Our paper on 12 A/B tests finds that quick, iterative experimentation produced large cost-effectiveness gains in an education program. Encouraging evidence for faster, rigorous learning in the social sector. @angrist_noam's summary🧵👇
📣 Our paper is out on 12 A/B tests all pulled together showing *big* efficiency gains! So excited about this paper and broader approach. We optimize tutoring programs, which are famously effective but hard to scale. Highlights below👇@WWHGlobalEd @youthimpactorg @BlavatnikSchool

Most studies take years. We ran 12 A/B tests on a remote education program in just 3 years. Small tweaks, tested iteratively → 📉 Costs down 21% 📈 Learning doubled when parents co-tutored Read our new working paper 👉 https://t.co/l244u7OZps

I'm on the #EconJobMarket! Millions of women dropped out of the labor force in rural India starting in the mid-2000s. Why? My #JMP shows that gendered commuting frictions + urban-biased growth is an important part of the answer. 🔗 https://t.co/sUebVghU8u
