Papers today from the NBER/BREAD conference on development economics:

1. The green revolution lies through meteorology? Indian farmers underinvest because rainfall forecasts are poor
2. How poverty affects cognitive function (now ungated)
3. Private school vouchers in India improve student performance at lower cost
4. But do parents even care student performance? 

Interesting in many respects, including how every paper is essentially a study of market imperfections.
