Abstract

RESUMEN: La existencia de brechas salariales por género es un fenómeno que, al igual que en muchos otros países, está presente en el mercado laboral colombiano. Esas brechas no son homogéneas en todo el territorio, lo que justifica un análisis detallado de lo que ocurre en cada una de las regiones del país. Los resultados muestran diferenciales de salarios positivos en favor de los hombres en la mayoría de las ciudades principales. Sin embargo, no todo este fenómeno puede ser atribuido a la existencia de discriminación, por cuanto existen variados factores que explican parte de la brecha salarial. Para identificarlos se emplea la descomposición de Blinder-Oaxaca (BO) en el contexto de regresión por cuantiles. Los resultados de la aplicación de esta metodología sugieren que las brechas salariales no están explicadas por los atributos observables de los individuos. Dichas disparidades son en su mayoría explicadas por el efecto de las diferencias en la remuneración de atributos tales como la educación, además de elementos no observados. Por ciudades, el estudio muestra patrones que revelan una mayor brecha salarial en las regiones periféricas en comparación con Bogotá, Cali, Medellín, Manizales y Pereira. Dado que el efecto remuneración comprende, entre otros, la posible existencia de discriminación por género, es importante que se le otorgue la debida atención a este resultado para efectos de formular políticas en este sentido.ABSTRACT: The evidence of gender pay gap is present in the Colombian labormarket, as in many other countries. This gap is not homogeneous in the territory,which provides the rationale for a detailed analysis of what is happening in each of the regions of the country. The results show differentials of positive wage gaps in favor of men, in most of the main cities. Not all this difference can be attributed to the existence of discrimination as there exist factors that explain part of the wage gap. To identify the relevance of those factors we use the Blinder-Oaxaca, BO, decomposition in the context of quantile regression. The results of the BOmethod suggest that wage gaps are not explained by the observable attributes of individuals. These gaps are mostly explained by the effect of pay gaps to attributes such as education, and unobserved attributes. The analysis by cities shows patterns that reveal a higher wage gap in the peripheral cities as opposed to Bogotá, Cali, Medellín, Manizales and Pereira. Differences in compensation to attributes are represented by what is known as the coefficients effect. This effect comprises as well the existence of discrimination by gender, thus this result deserves special attention for the purposes of gender equalizing payment policies
