摘要

An increasing number of police departments use information technology(IT) to optimize patrolling strategies,yet little is known about its effectiveness in preventing crime.Based on quasi-random access to"predictive policing,"this study shows that IT improves police productivity as measured by crime clearance rates.Thanks to detailed information on individual incidents and offender-level identifiers it also shows that criminals strategies are predictable.Moreover,the introduction of predictive policing coincides with a large negative trend-discontinuity in crime rates.The benefit-cost ratio of this IT innovation appears to be large.
