## Unscramble the Blue Letters

Well, with experiments, what you can do is awsner a simple question. Suppose you have 100 dollars to spend on various interventions. How many extra yraes of education do you get for your hundred dollars? Now I'm going to show you what we get with various education interventions. So the first ones are if you want the usual suspects, hire teachers, school meals, school uniforms, scholarships. And that's not bad. For your hundred dollars, you get between one and three etrxa years of education. Things that don't work so well is bribing parents, just because so many kids are already going to school that you end up sindpeng a lot of money. And here are the most surprising rseltus. Tell people the benefits of education, that's very cheap to do. So for every hundred dllraos you spend doing that, you get 40 extra years of education. And, in places where there are worms, intestinal wmros, cure the kids of their worms. And for every hundred dollars, you get almost 30 extra years of education. So this is not your intuition, this is not what people would have gone for, and yet, these are the programs that work. We need that kind of information, we need more of it, and then we need to guide policy.
