''Copula econometrics to simulate effects of private policing on crime''
( 2021, Vol. 41 No.3 )
Clotfelter´s model indicates that an increase in private policing has an ambiguous effect on crime across a city. Although this is often cited in the literature, we have found few attempts to test this hypothesis, perhaps because it involves several econometric challenges. This research presents a framework to solve this using city-level samples, applying copulas in Tobit marginals over indicators of crime and private policing. Using a sample of Brazilian cities, we find evidence in favor of Clotfelter´s hypothesis.
