↵Notes: Source is ENEM microdata. *p<0.1, **p<0.05, *** p<0.01. We report the results of our benchmark specification (Equation 1) adding the terms ds ⋅ below_HHIm and below_HHIm ⋅ privs with triangular kernels and optimal bandwidth as suggested by Calonico et al. (2016). Covariates: gender, age, race, parental schooling, family income, teacher schooling, presence of a science lab, ratios of teachers, computers, and staff to students. Metropolitan area fixed effects in all columns. Standard errors are clustered at the school level.
