A Spatial Analysis to Permanent Income as Deterrent of Homicides: the case of Medellin City

This paper studies the relationship between permanent income and homicides, estimating an income-crime elasticity. We assume that this elasticity varies across geographical areas. We estimate different specifications of Spatial Panel Models using information of urban areas in Medellin (Colombia), areas known as communes. Spatial Models consider the importance of location and the type of neighbors of each commune. We simulate an intervention over permanent income in order to estimate the income elasticity for each commune and the average elasticity of income-crime on the city. We provide evidence about spatial dependence between the homicides per commune and their neighbors, and about a relationship between homicides and neighbor’s income. In our case of study, the average estimated impact of 1% increase in permanent income in a specific commune produces a decrease in the homicide rate on average in 0.39%. Finally, permanent income plays a crime deterrent role, but also this effect of income on crime varies across the city, showing that some areas are strategically located to this kind of intervention.

El ser y el tener de los habitantes de la ciudad de Medellín como determinantes de la satisfacción con la vida

El presente estudio tiene como objetivo encontrar y analizar los efectos causales de diversos factores socioeconómicos y demográficos en la satisfacción con la vida de los hogares de Medellín. Para ello, se estima un modelo logístico, categorizando en dos grupos las variables explicativas: los aspectos inherentes al ser y las características relacionadas al tener. Los principales resultados sugieren que estar soltero en relación con otro estado civil tiene un efecto negativo en el bienestar subjetivo, así como el hecho de ser afrodescendiente con respecto a otro grupo étnico. Por el lado del tener, cabe resaltar que mayores niveles de educación y estratos socioeconómicos más altos incrementan el bienestar subjetivo. Se concluye que tanto las características del ser como las del tener son fundamentales para explicar la satisfacción con la vida, y por tanto, para la toma de decisiones de política pública.

Evidence of Discrimination Against Afrocolombians in the Colombian Labor Market in Major Cities in 2007

This paper evaluate the hypothesis that race is a determining factor in access to quality employment in Colombia during 2007 -- Using data from the Large Integrated Household Survey (2007-I), we estimate a generalized ordered logit model -- The results provide evidence that individuals self-identified as Afrocolombian have a higher probability of being in a low quality job than other Colombians -- This probability is higher by 1.9% in Cali, 3.4% in Bogotá, 12.6% in Barranquilla, 1.8% in Cartagena, 1.1% in Medellin and 3.8% overall in these five cities, results that could indicate that there is racial discrimination against Afrocolombians in the Colombian labor market
