Smoking bans have been prominent in recent health policy with consequences for individual welfare that are controversially discussed. According to traditional economics, bans constrain smokers in their habits what makes them worse off, while non-smoker are better off due to the protection from second-hand smoke. However, insights from psychology suggest time inconsistent smoking behavior so that bans may serve as a self-control device and benefit smokers as well. We evaluate the impact of smoking bans on subjective well-being analyzing data from the Eurobarometer for 38 European countries and regions since 2000 by applying a differences-in-differences approach.
