Objective: This study investigates the impact of the legalization of Sunday alcohol sales on several different types of criminal activity in the United States.

Method: The 2000–2010 data from the Federal Bureau of Investigation’s National Incident-Based Reporting System (NIBRS) for seven states (n = 1,746,249) and difference-indifferences type models are used to estimate the effect of the legalization of Sunday alcohol sales on different types of criminal activity.

Results: States that legalized Sunday sales of alcohol experienced up to a 16% to 23% increase in the total number of violent and property crimes committed on Sundays (p < .01). However, the aggregate impact of this policy change on crimes committed on all days of the week is not significant because of either positive or statistically insignificant spillover effects of the repeal of Sunday alcohol sales bans on crimes committed on Mondays through Saturdays. These results are robust under alternative model specifications.
