Are U . S . Cities Underpoliced ? : Theory and Evidence
نویسندگان
چکیده
We document the extent of measurement errors in the basic data set on police used in the literature on the effect of police on crime. Analyzing medium to large U.S. cities over 1960-2010, we obtain measurement error corrected estimates of the police elasticity. The magnitudes of our estimates are similar to those obtained in the quasi-experimental literature, but our approach yields much greater parameter certainty for the most costly crimes, which are the key parameters for welfare analysis. Our analysis suggests that U.S. cities are substantially underpoliced. JEL Classification: K42, H76, J18

Are U . S . Cities Underpoliced ? :
The socially optimal number of police hinges on the extent to which police reduce the most costly crimes, which are also the most difficult to model econometrically because they are rare. In the hope of minimizing simultaneity bias, papers in the recent literature have focused on quasi-experimental approaches that disregard most of the variation in police staffing levels, compounding the modeli...

متن کاملA Note on Belief Structures and S-approximation Spaces
We study relations between evidence theory and S-approximation spaces. Both theories have their roots in the analysis of Dempsterchr('39')s multivalued mappings and lower and upper probabilities, and have close relations to rough sets. We show that an S-approximation space, satisfying a monotonicity condition, can induce a natural belief structure which is a fundamental block in evidence theory...
متن کاملUrban Centralization in U . S . Cities prior to World War II :
EEective urban management and planning requires an understanding of the forces driving cities' development. Trends in population density and distribution are of particular importance, but are diicult to measure, and recent studies have come to connicting conclusions regarding the rate of decentralization in U.S. cities. We use a new metric to obtain new evidence regarding decentralization in U....
