To address the question of whether health has a causal impact on schooling, Miguel and Kremer (2004) randomly assigned deworming drugs (across schools) to children in Kenya. The PSDP project introduced de-worming drugs into 3 groups of schools. Groups 1& 2 will receive the drug and Group 3 is the control group The unit of randomization is at the school level Nancy Qian Econ 325: Lecture 4 Randomized Experiment: De-worming in Kenya Estimation Next Time Basic Problem Baseline Survey Sample Attrition Bundled Treatments Comparison Group Why Randomize? Why not just control for factors? Are there pitfalls to randomization? Why randomize across schools?
