Teacher vs Test based school recommendation, with Andrea Ichino and Giulio Zanella

We look at teacher and test based school recommendations in the Netherlands to disentangle the estimation bias and self-selection component in the regression from the causal effect. We thereby can identify the effect of teacher evaluation on self-esteem and school performance.

First results suggest that in the treatment group hospital referrals, costs as well as returns of patients to the clinic were lower compared to the control group.
