An analysis of the relationship between wages in the public and private sector in colombia : a panel data approach

This document examines the time-series properties of the wage differentials that arise between the public and private sector in Colombia during the sample period 1984 to 2005. We Find conflicting results in unit-root and stationary tests when looking at wage differentials at an aggregate level (such as for men, women or both). However, when we analyse wage differentials at higher levels of disaggregation, treat them jointly as a panel of data, and allow for the presence of potential cross section dependence, there is more supportive evidence for the view that wage differentials are stationary. This implies that although wage differentials do exist, they have not been consistently increasing (or decreasing) over time.

Un marco analítico de la discriminación laboral. Teorias, modalidades y estudios para Colombia

Este documento presenta un resumen de las principales corrientes teóricas que han tratado de dar una explicación a la discriminación laboral, asi como una exposición pedagógica de las principales modalidades mediante las cuales dicha discriminación se manifiesta. Se realiza un particular análisis de las consecuencias que dicha discriminación tiene, en particular para el caso de los jóvenes de América Latina, y finalmente se realiza una revisión de los estudios que sobre el tema se han realizado en Colombia, sus aspectos metodológicos y las conclusiones a las que dichos estudios han llegado.

Diferencias regionales en las estructuras de ingresos laborales en Colombia

Dada la persistencia de las diferencias en ingresos laborales por regiones en Colombia, el presente artículo propone cuantificar la magnitud de este diferencial que es atribuida a la diferencia en estructuras de mercado laboral, entendiendo esta última como la diferencia en los retornos a las características de la fuerza laboral. Para ello se propone el uso de un método de descomposición del tipo Oaxaca- Blinder y se compara a Bogotá –la ciudad con mayores ingresos laborales- con otras ciudades principales. Los resultados obtenidos al conducir el ejercicio de descomposición muestran que las diferencias en estructura están a favor de Bogotá y que estas explican más de la mitad de la diferencia total, indicando que si se quieren reducir las disparidades de ingresos laborales entre ciudades no es suficiente con calificar la fuerza laboral y que es necesario indagar por las causas que hacen que los retornos a las características difieran entre ciudades.

An approximation to the informal-formal wage gap in Colombia 2008-2012

This document provides recent evidence about the persistency of wage gaps between formal and informal workers in Colombia by using a non-parametric method proposed by Ñopo (2008a). Over a rich dataset at a household level during 2008-2012, it is found that formal workers earn between 30 to 60 percent more, on average, than informal workers. Despite of the formality definition - structuralist or institucionalist- adopted, it is clear that formal workers have more economic advantages than informal ones, but after controlling by demographic and labor variables an important fraction of the gap still remains unexplained.

Is there a motherhood penalty? decomposing the family wage gap in Colombia

The aim of this paper is to provide an estimation and decomposition of the motherhood wage penalty in Colombia. Our empirical strategy was based on the matching procedure designed by Ñopo (The Review of Economics and Statistics, 90(2), 290–299, 2008a ) for the case of gender wage gaps. This is an alternative procedure to the well-known Blinder–Oaxaca decomposition method. Using the cross-sectional data of the Colombian Living Standard Survey, the wage gap was decomposed into four components, according to the characteristics of mothers and non-mothers. Three of the components are explained by differences in observable characteristics of women, while the other is the unexplained part of the gap. We found that mothers earn, on average, 1.73 % less than their counterparts without children and that this gap slightly decreased when the group included older women. It is observed from the results that, once schooling was included as a matching variable, the unexplained part of the gap considerably decreased and became non-significant. Thus, we did not find evidence of wage discrimination against mothers in the Colombian labor market. Copyright Springer Science+Business Media New York 2013

Diferenciales salariales por género y región en Colombia: Una aproximación con regresión por cuantiles

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 ofthe regions of the country. The results show differentials of positive wage gaps infavor of men, in most of the main cities. Not all this difference can be attributedto the existence of discrimination as there exist factors that explain part of thewage 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 ofindividuals. These gaps are mostly explained by the effect of pay gaps to attributessuch as education, and unobserved attributes. The analysis by cities shows patternsthat reveal a higher wage gap in the peripheral cities as opposed to Bogot´a, Cali,Medellín, Manizales and Pereira. Differences in compensation to attributes arerepresented by what is known as the coefficients effect. This effect comprises aswell the existence of discrimination by gender, thus this result deserves specialattention for the purposes of gender equalizing payment policies
