From late 2017 to early 2019, one of the two french law enforcement agencies tested in 11 out of 101 departments a predictive policing system named PAVED. The system design by the Gendarmerie predicts burglaries and vehicle thefts with the stated objective of better allocating patrols and thus increasing deterrence. We use month-law enforcement jurisdiction area panel data to evaluate whether the system produces the expected reduction in these thefts and whether this effect is due to a deterrent effect or a displacement effect. Both the standard Two Way Fixed Effect and Synthetic Difference-in-Difference estimations consistently indicate a significant reduction of vehicle thefts in the treated Gendarmerie areas but no detectable effect on burglaries. Most of our results indicate that vehicle theft has not increased in areas near the treated areas, suggesting that the reduction in vehicle theft is due to a deterrent effect rather than a displacement effect.
