Non-resident fellow Michael Kremer was featured in Nick Kristof's column in the New York Times.
From the Article:
Prof. Michael Kremer, a Harvard economist, helped pioneer randomized trials in antipoverty work. In the 1990s, Kremer began studying how to improve education in Africa, trying different approaches in randomly selected batches of schools.
One intervention he tried was deworming kids — and bingo! In much of the developing world, most kids have intestinal worms, leaving them sick, anemic and more likely to miss school. Deworming is very cheap (a pill costing a few pennies), and, in the experiment he did with Edward Miguel, it resulted in 25 percent less absenteeism. Even years later, the kids who had been randomly chosen to be dewormed were earning more money than other kids.
Kremer estimates that the cost of keeping a kid in school for an additional year by building schools or by subsidizing school uniforms is more than $100, while by deworming kids, the cost drops to $3.50. (In a pinch, kids can usually go to “school” in a church or mosque without a uniform.)
