The Effect of a Sunday Liquor-Sales Ban Repeal on Crime: A Triple-Difference Analysis

초록

BackgroundThis study investigates whether alcohol availability in state-run liquor stores affects crime nearby. In 2003, Pennsylvania repealed its Sunday alcohol-sales ban for a portion of its state-run liquor stores. We capitalize on this change in alcohol policy to assess the effect of alcohol availability on crime occurring within the vicinity of liquor stores that opened on Sundays in Philadelphia. MethodsWe employed a difference-in-difference-in-differences model that compared reported crime before versus after the change in alcohol policy, Sundays versus other days of the week, and the fraction of liquor stores affected versus not affected by the repeal. We used crime incident data in Philadelphia between 1998 and 2011. ResultsThe repeal was associated with a significant increase in total and property-crime incidents occurring around Sunday-open state liquor stores in low-socioeconomic-status neighborhoods. We found no evidence of the displacement of crime to nearby areas. ConclusionsThis is the first triple-difference alcohol study that attempts to isolate the micro-spatial effects of a shift in alcohol availability on local crime patterns, and shows that the repeal of Sunday alcohol-sales restrictions may increase crime in poor urban areas.
