This paper studies whether bartenders that adopt standardized practices can promote responsible alcohol consumption and subsequently reduce alcohol-attributable violence. We conduct a randomized experiment in four localities of Bogota´ in cooperation with Colombia’s largest brewery and Bogota’s Secretariat of Security, Coexistence, and Justice. Our ´ design allows estimating direct and spillover effects on reported incidents within and around bars. Results show that bartenders in treatment locations sell more water and food, thus contributing to more responsible alcohol consumption by patrons. We find no direct or spillover effects of these changes in consumption on brawls, but some improvement on other alcohol-related incidents.
