    Efecto de los Ingresos Permanentes sobre el Delito: Un Enfoque Espacial y un Caso de Aplicación
    (Universidad EAFIT, 2014-02-20) Gómez Toro, Catalina; Velásquez, Hermilson; Urrego, Joaquín Andrés; Valderrama, Juan David
    This paper analyzes the impact of increment in the permanent income on crime in each spatial unit and their neighbors. Different specifications of spatial panel data are estimated to capture the effects of spatial distribution and income on crime. In the particular case of Medellin, the estimated impact of increase 1% in permanent income in specific commune is a decrease in crime near to 0,67%, and the effects of each neighbor are variable and significant. Tests statistics can show the robustness of the conclusions and the adequate specification of the model.

    Efecto de los ingresos permanentes sobre el delito: un enfoque espacial y un caso de aplicación
    (Universidad Nacional Autónoma de México, 2016-10-01) Urrego, Joaquín A.; Gómez, C.; Velásquez, H.; Valderrama, Juan David; Universidad EAFIT. Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)
    In this study, spatial information is used to complement the analysis that crime makes an economic theory focused on the availability of police force and judicial efficiency. Particularly, this document analyzes the role that the level of permanent income plays in crimes in a geographical unit and its neighbors, in addition to the relationship of socioeconomic characteristics. An exercise that was applied in the communes of Medellin confirmed the idea that an increase in permanent revenues of 1% reduces crimes in the communes on average by 0.67%. The effect this has on its neighbors is significant and variable. Traditional panel models underestimate the real impact that an increase in income in some neighborhoods has. Robust tests show the accuracy of the results and the adequacy of the model data generating process. © 2016 Universidad Nacional Autónoma de México, Facultad de Economía
