Quasi‐Experimental Price Elasticities of Cigarette Demand and the Bootlegging Effect
更新了香烟需求的准实验价格弹性，研究其随时间的变化趋势以及走私行为的影响，发现弹性呈下降趋势且走私导致高估，但调整对照组后差异不再显著。
This paper updates the Lyon and Simon quasi‐experimental price elasticities of cigarette demand and studies their sensitivity to changes in the cigarette market over time as well as their sensitivity to the effects of bootlegging. The results indicate a downward trend in these elasticities over time and an upward bias for states where bootlegging exists. However, once the comparison group is modified to include bootlegging‐free states only, this difference over time and across groups becomes statistically insignificant.
