Testing for the assumption of independence between spatial variables is an important first step in spatial conometrics. Usually the researchers use the bivariate generalization of the Moran’s statistic, specifying a spatial matrix a priori. This test is applicable only to detect linear...

This paper studies the effects of school attributes on test scores in the city of Bogotá. The paper shows, first, that both teacher-pupil ratios and teacher education are positively correlated with higher test scores, and, next, that these associations are circumscribed to private schools. In...
