The harmful effects of secondhand smoke are convincing more and more communities across the United States and the world to prohibit smoking in public places, especially in eating and drinking establishments. A 1993 Missouri state law allows smoking in designated areas in indoor public places such as restaurants and bars. Consequently, some Missouri communities have adopted local ordinances that prohibit smoking in all indoor workplaces, including restaurants and bars. We used an objective measure of economic activity, the taxable sales revenues of eating and drinking establishments, to empirically examine the economic effect of smoke-free ordinances.
We studied the economic effect of smoke-free ordinances in 11 Missouri cities using multivariate log-linear regression models with log-transformed taxable sales revenues of eating and drinking establishments as the dependent variable and the smoke-free ordinance as the independent variable, while controlling for seasonality, economic condition and unemployment. We used data from 20 quarters before the smoke-free ordinances and at least 10 quarters after the smoke-free ordinances for all cities. The null hypothesis of no effect of smoke-free ordinance on taxable sales of the eating and drinking establishments was tested.
Eight of the 11 cities had increased taxable sales for eating and drinking establishments postordinance. The remaining 3 experienced no change.
The findings of our study are consistent with findings from most published economic studies that a smoke-free ordinance does not harm a local economy.
二手烟的有害影响越来越让美国乃至全世界的社区相信，应该在公共场所禁烟，尤其是在饮食场所。1993 年，密苏里州的一项州法律允许在餐厅和酒吧等室内公共场所的指定区域吸烟。因此，一些密苏里州的社区通过了禁止在所有室内工作场所（包括餐厅和酒吧）吸烟的地方法令。我们使用了衡量经济活动的客观指标，即饮食场所的应纳税销售收益，来实证检验无烟条例的经济影响。
我们使用多元对数线性回归模型，以饮食场所的应纳税销售收益的对数为因变量，以无烟条例为自变量，对 11 个密苏里州城市的无烟条例的经济影响进行了研究，同时控制了季节性、经济状况和失业率。我们使用了所有城市在无烟条例实施前 20 个季度和实施后至少 10 个季度的数据。我们对无烟条例对饮食场所应纳税销售额没有影响的零假设进行了检验。
11 个城市中有 8 个城市在实施无烟条例后，饮食场所的应纳税销售额有所增加。其余 3 个城市则没有变化。
我们的研究结果与大多数已发表的经济研究结果一致，即无烟条例不会损害当地经济。
