... tudy has explicitly studied the link between arson and collective efficacy at the neighborhood level. The present study attempts to fill this gap by analyzing the association between arson and collective efficacy in the city of Malmö, Sweden. Collective efficacy data from 96 neighborhoods were collected in 2012 in the Malmö Community Survey (N=4051). Arson data were collected from the rescue services, which employ GPS-receivers to accurately record the location of incidents. Multivariate regression models were fitted for the number of incidents of arson per capita, controlling for concentrated disadvantage, ethnic heterogeneity and residential stability. Results show no significant link between collective efficacy and arson following appropriate controls. This suggests that arson may depend on mechanisms other than collective efficacy, at least at the neighborhood level. Future research may need to focus on alternative theoretical explanations such as strain, or on other levels of analysis than neighborhoods.
