Evaluating An Alternative To Finance Higher Education: Human Capital Contracts In Colombia.

Se presenta un ejercicio para la valuación de Contratos de Capital Humano (CCH), siguiendo a Palacios (2004), en el cual se utilizan datos del Observatorio Laboral para la Educación y su Encuesta de Seguimiento a Graduados–2007. El análisis se hace a través de un modelo Monteriano y uno de Splines para encontrar los pronósticos determinísticos del ingreso. Se encuentra que los retornos a la educación superior proveen un incentivo para la implementación de CCHs para financiar completamente los programas de las universidades públicas y parcialmente en las universidades privadas. Financiar los programas de las universidades privadas requiere más ayudas para hacer los contratos rentables para los inversionistas y atractivos para los estudiantes.

Psycological violence against women in Colombia

Although violence against women has gain attention, there is little evidence of studies about phycological violence against a partner. This paper uses data from Encuesta Nacional de Demografíay Salud (ENDS) to assess empirically models of violence against a partner. One of the main findingsis that the higher the economic independence of the women, the lower the phycologicalviolence against a partner. Some other results show that women with higher education level, belongingto a violent or low income family and living in cities different from Bogotá is correlatedwith higher probability of phycological violence.

A revised Tobit procedure for mitigating bias in the presence of non-zero censoring with an application to milk-market participation in the Ethiopian highlands

Fixed transactions costs that prohibit exchange engender bias in supply analysis due to censoring of the sample observations. The associated bias in conventional regression procedures applied to censored data and the construction of robust methods for mitigating bias have been preoccupations of applied economists since Tobin [Econometrica 26 (1958) 24]. This literature assumes that the true point of censoring in the data is zero and, when this is not the case, imparts a bias to parameter estimates of the censored regression model. We conjecture that this bias can be significant; affirm this from experiments; and suggest techniques for mitigating this bias using Bayesian procedures. The bias-mitigating procedures are based on modifications of the key step that facilitates Bayesian estimation of the censored regression model; are easy to implement; work well in both small and large samples; and lead to significantly improved inference in the censored regression model. These findings are important in light of the widespread use of the zero-censored Tobit regression and we investigate their consequences using data on milk-market participation in the Ethiopian highlands.
