¿La sobreeducacion de los padres afecta al rendimiento academico de sus hijos?

El objetivo del trabajo consiste en analizar si el desajuste educativo de los progenitores afecta a los resultados educativos de los hijos. Para ello, se utilizan los microdatos de PISA-2009 para España, dado que facilita información detallada sobre el rendimiento educativo de los estudiantes, sus características personales y la de su entorno escolar y familiar lo que la hace idónea para llevar a cabo el estudio planteado. Los resultados obtenidos muestran que los estudiantes con progenitores sobreeducados tienen una penalización en su rendimiento académico en las tres materias analizadas, siendo ésta más intensa para los estudiantes con peores resultados educativos.

Overeducation, skills and wage penalty: Evidence for Spain using PIAAC data

The literature on educational mismatches finds that overeducated workers suffer a wage penalty compared with properly educated workers with the same level of education. Recent literature also suggests that individuals’ skill heterogeneity could explain wage differences between overeducated and properly matched workers. The hypothesis is that overeducated workers earn less due to their lower competences and skills in relative terms. However, that hypothesis has been rarely tested due to data limitations on individuals’ skills. The aim of this paper is to test the individuals’ skill heterogeneity theory in Spain using microdata from PIAAC, because it is one of the developed countries supporting the highest overeducation rates and where its adult population holds the lowest level of skills among a set of developed countries. Our hypothesis is that the wage penalty of overeducation in Spain is explained by the lower skill level of overeducated workers. The obtained evidence confirms this hypothesis but only to a certain extent as skills only explain partially the wage penalty of overeducation.
