An interesting, recently revised working paper by Duflo, Dupas and Kremer looks at the effects of providing school uniforms, teacher training on HIV education, and the two combined. This paper is useful in a number of dimensions – it gives us some sense of the longer term effects of these programs, the methodology is interesting (and informative), and finally, of course, the results are pretty intriguing and definitely food for thought.
long run effects
Following up on Michael’s post yesterday, I wanted to add a couple of thoughts.
If one wants to grow an oak tree, it helps to have both an acorn and a working knowledge of the conditions under which an acorn is most likely to become an oak tree. One also needs to know how long the germination process is likely to take – in the case of the red oak, upwards of two years from flowering to acorn to sapling. Absent such knowledge, one might reasonably (but incorrectly) infer that, upon seeing no outward signs of life six months after planting the acorn, one’s efforts had been in vain.
