Finally a Smoking Gun? Compensating Differentials and the Introduction of Smoking Bans
利用德国酒店业2007-2008年分阶段引入禁烟令，发现最全面禁烟令使酒吧和餐厅工人日收入下降2.4%，且该效应与补偿性工资差异模型一致，而非收入或工时减少所致。
Using the staggered introduction of smoking bans in the German hospitality industry over 2007–2008, I find a robust 2.4 percent decline in the daily earnings of workers in bars and restaurants associated with the most comprehensive smoking ban. This effect is unlikely to be driven by a decline in hospitality revenues or hours worked but is consistent with a simple model of compensating differentials.
