Cidades e Violência: Uma Análise Empírica do Caso de Costa Rica

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Este artigo foca no efeito da urbanização no que tange a crimes violentos – particularmente homicídios – na Costa Rica. Apesar de a violência ser um grave problema em toda a América Latina, poucos estudos empíricos conduzidos nessa área usam bancos de dados socioeconômicos e de criminalidade de alta qualidade, com alto nível de desagregação geográfica. Neste artigo, empregamos dados de todos os 473 distritos de Costa Rica entre 2010 e 2013. Desenvolvemos um modelo que leva em consideração problemas de endogeneidade e usa contrastes de predições lineares marginais. Concluímos que o grau de concentração urbana desempenha um papel determinante na explicação de taxas de homicídio, mantendo constantes as demais variáveis. Esse efeito é progressivo: quanto maior a concentração urbana, maiores são as taxas de homicídio. Essa relação causal não é observada em outros crimes.
