The Impact of the First Professional Police Forces on Crime
 
Abstract: This paper evaluates the effect on crime of creating a fundamental modern-day institution: centralized professional police forces tasked with preventing crime. We study the 1829 formation of the London Metropolitan Police – the first professional force worldwide. Using newly digitized and geocoded crime and police data together with difference-in-differences and pre-post designs, we find evidence of a significant reduction of violent crimes (despite the possibility of off-setting increases in clearance and reporting rates). In contrast, a reduction in property crime is not visible.
