Does urbanization cause crime? Evidence from rural–urban migration in South Africa
We study the impact of urbanization driven by internal migration on crime in South Africa. We create a new dataset that combines yearly data on crime and urban population density at the municipality level from 2011 to 2018. We exploit exogenous variations in rural–urban migration induced by climate shocks at origin for identification. We show that higher urban population density leads to a reduction in pecuniary crime rate but has no effect on non-pecuniary crime rate. This negative effect operates through changes in population composition and a social network effect.
期刊介绍:
The Journal of Urban Economics provides a focal point for the publication of research papers in the rapidly expanding field of urban economics. It publishes papers of great scholarly merit on a wide range of topics and employing a wide range of approaches to urban economics. The Journal welcomes papers that are theoretical or empirical, positive or normative. Although the Journal is not intended to be multidisciplinary, papers by noneconomists are welcome if they are of interest to economists. Brief Notes are also published if they lie within the purview of the Journal and if they contain new information, comment on published work, or new theoretical suggestions.
