Abstract:

This paper studies the impact of crewing size on the productivity of policing. Exogenous variation in crewing size originating from the introduction of the ‘Banded Pattern’- an initiative by which West Midlands Police boosted deployment in Response Teams in 2018 – is exploited empirically. In comparison with single-crewing, double-crewing generates net improvements in crime clearance rates. Estimates also show that double-crewing reduces the risk of serious injury of police officers during an assault. This reflects greater proactivity and safety of police officers in dangerous situations. In addition, benefits from team complementarities in terms of experience, gender and seniority are documented.
