Conflict, Crime and Violence

We exploit detailed information on location and exact date of installation of policemonitored surveillance cameras coupled with daily data at the street-segment level on all reported crimes in the city of Montevideo, Uruguay, to study the impact of police monitoring on crime. The introduction of police-monitored surveillance cameras reduces crime by 28 percent in monitored areas relative to un-monitored areas of the city. Results are robust to alternative definitions of the control group. A series of placebo experiments reassure that the findings have a causal interpretation. We find evidence that the reduction in crime in police monitored areas of the city is compensated by an increase in crime in other areas of the city.
