Policing underage alcohol sales

Abstract

This study evaluates an enforcement program targeted at licensed retail sellers of alcohol. The program was a sting or decoy operation in which underage police cadets attempted to purchase packaged beer at randomly selected grocery, convenience, liquor, and drug stores in Denver, Colorado. Stores that sold alcohol to the underage purchasers were subject to fines and beverage license suspensions. During baseline, cadets purchased beer 59% of the time. The purchase rates for successive waves of enforcement conducted over the next 10 months were 32%, 26%, and 26%.
