March 25 Police Do Matter

from POLICING FOR CRIME PREVENTION (by Lawrence W. Sherman)

re: Marvell, Thomas B. and Carlisle E. Moody
1996 Specification Problems, Police Levels and Crime Rates. Criminology 34: 609-646.


"The Marvell and Moody (1996: 632) analysis also allows a test of the hypothesis that the prevention benefits of hiring more police officers are greater in higher-crime cities than across the country in general. The analysis estimates that for each additional officer added to a police force in a big city, 24 Part I crimes are prevented annually."



Also, here are a number of links to sources of studies and datasets relating to crime rates.

Oh, and on the subject of academic self-examination, if you were impressed by Al Gore's An Inconvenient Truth, you'll find the following critique even less convenient.
