The Impact of Smoking Bans in Bars on Alcohol Consumption and Smoking
研究酒吧禁烟令对饮酒和吸烟行为的影响，发现禁烟令导致每月饮酒量增加约1杯（5%），对吸烟无显著影响，且效应集中在当前和曾经吸烟者中。
Governments implemented smoking bans in bars to target smoking-related externalities, but these bans may also affect drinking. This paper studies smoking bans’ effects on alcohol consumption and smoking behavior. I estimate a difference-in-differences model that exploits spatial and temporal variation in smoking bans. Bans result in a 1-drink-per-month (5 percent) increase in intensive-margin alcohol consumption and no economically meaningful effects on smoking. Effects on alcohol consumption are concentrated among current and former smokers. These results imply that smoking bans lead to unintended consequences in the form of increased alcohol consumption.
