摘要

I study the effects of surveillance cameras on crime in the Stockholm subway system. Beginning in 2006, surveillance cameras were installed in subway stations at different points in time. Difference-in-difference analysis reveals that introduction of the cameras reduced crime by approximately 25% at stations in the city centre. The types of crimes deterred by cameras are planned crime, that is, pickpocketing and robbery. It is also shown that some of the crimes were displaced to surrounding areas. The cost of preventing one crime by the use of surveillance cameras is approximately US$ 2,000.
