Heterogeneidad del colegio y desempeño académico

Abstract

This research aims to examine the relationship between heterogeneity within schools and academic performance. For this purpose, two measures of heterogeneity are constructed, using entropy indices, which capture the heterogeneity among students of the same school in the levels of household wealth and in the educational levels reached by the parents. It is found, under both measures, that the level of heterogeneity is higher for official schools than for non-official schools. The theoretical model used to derive the empirical implications establishes that higher levels of heterogeneity among students in a school increase the academic performance of students, however, when balancing the sample there is no evidence of the effect of heterogeneity on performance.
