    Subiendo las escaleras : efectos de las Intervenciones urbanas sobre el crimen
    (Universidad EAFIT, 2018) Alzate Suárez, Erwin; García Cruz, Gustavo Adolfo
    This paper explores the relationship between unconventional transportation systems and their impact on crime. In 2011, Medellin (Colombia) manages to integrate a historically social and economic marginalized area through the use of electric stairs as a massive transportation system. This is why through a Difference in Difference approach, we seek to stablish if this intervention is able to reduce crime. The results show how the transportations system and the interventions made with it can serve as reinforcement for the public force actions and area´s security improvement. We also identified the need to use an unusual outcome variable since the area’s public order characteristics make it impossible to use homicides as a result variable.
