There is widespread evidence that smoking is more spread among the least well-off, but few studies investigate the effects of the differentiation of smoking products. This paper provides new evidence on income related inequality of five different products using a database from the Italian Population Survey on Alcohol and other Drugs. In particular, we use the 2014 and 2018 surveys to estimate how the consumption of manufactured cigarettes, roll-your-own cigarettes, cigars, pipe, and e-cigarettes is distributed across the income scale. The results confirm the existing evidence that the use of manufactured and roll-your-own cigarettes is more concentrated among the poor, while the use of cigars and pipe tends to be more concentrated among richer individuals. On the other hand, an important result emerges that the use of electronic cigarettes appears to be more concentrated among the poor, giving support either to the possibility that e-cigs may induce entry into smoking at cheaper prices for less affluent people or that it helps downtrading and quitting of traditional smokers in the lowest part of the income distribution. In both cases, the policy implications, for example of how to tax these alternative products, are relevant, especially because individual socio-economic characteristics (gender, income, education, working condition and geographical location) play a significant and differentiated role across smoking products.
有广泛的证据表明,吸烟在最贫困人群中更为普遍,但很少有研究调查吸烟产品差异化的影响。本文利用意大利酒精和其他药物人口调查数据库,就五种不同产品的收入相关不平等问题提供了新的证据。具体而言,我们使用 2014 年和 2018 年的调查数据,估计了成品卷烟、自卷烟、雪茄、烟斗和电子烟在收入水平上的分布情况。结果证实了现有证据,即使用成品卷烟和自卷烟的人群更为集中在贫困人群,而使用雪茄和烟斗的人群则更集中在富裕人群。另一方面,一个重要的结果是,电子烟的使用似乎更为集中在贫困人口中,这要么支持电子烟可能以更便宜的价格吸引不太富裕的人开始吸烟的可能性,要么支持电子烟帮助收入分配最低部分的传统吸烟者减少吸烟量和戒烟的可能性。在这两种情况下,政策含义都很重要,例如如何对这些替代产品征税,特别是因为个人社会经济特征(性别、收入、教育、工作状况和地理位置)在不同的吸烟产品中起着重要且有差异的作用。
