Abstract

This working paper explores the effect of joint labor decisions on the study of wage regression models. The estimation of Mincer equations suffers from numerous sources of bias, including the sample selection problem generated by the fact that the agent decision to work is not independent of the wage. Most of the papers corrects this bias using a model of individual labor participation. However, recent trends in the labor market show greater participation of women in the labor force and seem to indicate that the joint decision of the spouses is increasingly relevant in determining the selection mechanism. A bivariate version of Heckman's method appears as an interesting alternative to solve this problem. Although the estimates are in line with the previous literature, the results indicate that the joint decision of the couple is a relevant factor in the selection bias. Este documento de trabajo explora el efecto de las decisiones laborales conjuntas sobre el estudio de los determinantes del salario laboral. La estimación de ecuaciones de Mincer sufre de numerosas fuentes de sesgos, entre ellas el problema de selección muestral generado por el hecho de que la decisión de trabajar no es independiente del salario individual. La mayoría de los trabajos corrigen dicho sesgo consideran un modelo de participación laboral individual. Sin embargo, las tendencias recientes del mercado laboral muestran una mayor participación de las mujeres en la fuerza de trabajo y parecieran indicar que la decisión conjunta de los cónyuges es cada vez más relevante en la determinación del mecanismo de selección. Una versión bivariada del método de Heckman permite incorporar una solución cuantitativa a este problema. Si bien las estimaciones realizadas están en línea con la literatura previa, los resultados indican que la decisión conjunta de la pareja es un factor relevante en el sesgo por selección muestral.
