Patrol officer productivity is an understudied topic in police research. Prior studies on productivity have primarily relied on rudimentary statistics, such as calls for service and arrests. A more advanced method for evaluating productivity should (a) account for the diverse activities of patrol officers, (b) weight different productivity outputs, (c) evaluate officers in terms of available minutes for self-initiated activities (productive time), and (d) offer agencies the flexibility to select, prioritize, and weight patrol activities most relevant to their jurisdictions. Borrowing from a baseball sabermetric called Value Over Replacement Player, we create and test an innovative statistic called Value Over Replacement Cop. This metric analyzes 12 patrol activities and generates a single number by which to quantify and evaluate a patrol officer’s productivity. Using data from a midsize U.S. Police Department (325 sworn officers), we find strong support for the validity of this new metric.
