Este trabajo presenta una discusión acerca de los retornos a la inversión en educación y de su estimación para el caso colombiano. El marco teórico esta dado por la literatura del capital humano en educación, los aspectos de estimación de dichos retornos, los problemas de omitir en la especificación econométrica el efecto de variables como la habilidad de los individuos y la forma en que se ha intentado solucionar el sesgo derivado de tal omisión. Para la estimación de los retornos educativos se utilizaron dos bases en diferentes periodos del tiempo. La primera es una encuesta realizada para trabajadores bogotanos en 1988 y la segunda, la Encuesta de Calidad de Vida de 1997. Aunque dichas encuestas no son comparables entre si, se encuentra un sesgo de habilidad positivo, al parecer no muy significativo. Al utilizar una variable de caracterización socioeconómica como instrumento para la corrección de los retornos se encuentra una sobreestimación de los mismos, resultado similar al encontrado en la literatura internacional. Además, se muestra evidencia de poca movilidad intergeneracional, ya que trabajadores cuyos padres tienen educación superior obtienen unos mayores retornos. ************************************************************************ This work presents a discussion about the returns to the investment in education and its estimation to the Colombian case. The theory framework is gave by the literature of the human capital in education, the aspects of estimation of these returns, the problems to omit in the econometric specification the effect of variables as the ability of the individuals and the form in which the bias derived from such omission has tried to be solved. For the estimation of the educative returns two data in different periods from the time were used. The first, originating one of a survey made for Bogotá's workers in 1988 and second, from the "Encuesta de Calidad de Vida" of 1997. Although these surveys are not comparable, there is a positive ability bias, apparently not very significant. When we use a variable of socioeconomic characterization as instrument for the correction of the returns there is an upward bias; this result is similar to the found in international literature. In addition, there is evidence of little intergenerational mobility, since workers whose parents have higher education obtain greater returns.
