Racial Bias in Motor Vehicle Searches: Theory and Evidence
Police checking for illegal drugs are much more likely to search the vehicles of African‐American motorists than those of white motorists. This paper develops a model of police and motorist behavior
A Theory of Optimal Random Crackdowns
An incentives based theory of policing is developed which can explain the phenomenon of random "crackdowns," i.e., intermittent periods of high interdiction/ surveillance. For a variety of police
A Search-Theoretic Model of the Retail Market for Illicit Drugs
A search-theoretic model of the retail market for illegal drugs is developed. Trade occurs in bilateral, potentially long-lived matches between sellers and buyers. Buyers incur search costs when
An Economic Analysis of Black-White Disparities in the New York Police Department’s Stop-and-Frisk Program
We introduce a model to explore the identification of two distinct sources of bias in the New York Police Department’s stop-and-frisk program: the police officer making the stop decisions and the
A Rational Theory of Random Crackdowns ∗
This paper develops an incentives-based theory of policing that can explain the phenomenon of random “crackdowns,” which are intermittant periods of especially high interdiction/surveillance. We show
The Hit Rates Test for Racial Bias in Motor‐Vehicle Searches
This paper exposits a rational choice model of police–motorist interactions originally developed in Knowles, Persico, and Todd (Knowles, J., Persico, N., & Todd, P. [2001]. Racial bias in motor
Information Acquisition and the Exclusion of Evidence in Trials
A peculiar principle of legal evidence in common law systems is that probative evidence may be excluded in order to increase the accuracy of fact-finding. A formal model is provided that rationalizes
An Economic Analysis of Black-White Disparities in Nypd's Stop and Frisk Program
We analyze data on NYPD's "stop and frisk program" in an effort to identify racial bias on the part of the police officers making the stops. We find that the officers are not biased against African
Multitasking, Multiarmed Bandits, and the Italian Judiciary
We model how a judge schedules cases as a multiarmed bandit problem. The model indicates that a first-in-first-out (FIFO) scheduling policy is optimal when the case completion hazard rate function is
Minimum Wage and Individual Worker Productivity: Evidence from a Large US Retailer
We study the effect of increasing the statutory minimum wage on individual worker productivity. Within a workforce of base+commission salespeople from a large US retailer, and using a
