Evaluating Crime Attributable to Casinos in the U.s.: a Closer Look at Grinols and Mustard’s “casinos, Crime, and Community Costs”

This paper examines problems in studying the relationship between casinos and crime, with a focus on a recently published, infl uential study (Grinols and Mustard 2006) which concluded that casinos cause a signifi cant amount of county-level crime in the U.S. Five key issues are examined. First, the most serious problem with their analysis is that it uses a crime rate that excludes the visiting population at risk, thereby overstating the crime rate in casino counties. Second, the crime data used are potentially inaccurate. Third, the results may suffer from a bias caused by counties self-selecting into the “casino county” category. Fourth, the dummy variables used to account for casinos do not allow the authors to isolate the crime effect caused by casinos. Finally, the authors make conclusions that are not supported by their data, analysis, and results. An examination of these issues is important because it will shed additional light on the debate over the effects of casinos, and provides valuable information for subsequent researchers who study the casino-crime relationship.
