Dispute resolution and “environmental” provisions in the WTO: promising developments for environmental matters

En la actualidad, la política internacional tiende hacia la unificación económica y cultural (globalización), en la cual la totalidad de las naciones se encuentran vinculadas por interacciones comerciales. Para que los compromisos adquiridos en materia de protección ambiental sean respetados, el derecho ambiental debe dejar de ser considerado como una disciplina separada y buscar sinergias que le permitan convertirse en un actor importante en las relaciones comerciales. En el presente ensayo se argumenta que el comercio internacional y el derecho ambiental han coevolucionado en las últimas tres décadas, hasta llegar a un balance en el concepto de desarrollo sostenible.Este artículo explora esta coevolución, mientras propone que la Organización Mundial del Comercio (OMC) puede jugar un importante rol en el cumplimiento de los objetivos internacionales de protección ambiental si sus disposiciones “verdes” y su sistema de resolución de conflictos son utilizados para promoverlos, tal como está sucediendo. Para ilustrar este punto, se presenta un breve resumen de los tratados comerciales y ambientales suscritos desde los años setenta, seguido de una explicación de las disposiciones legales de la OMC que pueden ser consideradas como “verdes”, con el fin de hallar puntos de convergencia que puedan ser utilizados por los países miembros no solo para justificar la adopción de normativas domésticas de protección ambiental, sino también para instar a los otros signatarios en el cumplimiento de sus obligaciones en esta área.

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
