We examined the influence of cigarette taxes on tobacco consumption, with an emphasis on smokers' choice between reducing cigarette consumption and switching brands. We constructed three scenario-based models to study the following two subjects: (1) the relationship between deciding whether to reduce one's cigarette consumption and to practice brand switching (simultaneous or sequential); (2) the key determinants that affect smokers' decisions in terms of their consumption and brand switching when facing higher taxes. We applied data collected from a survey in Taiwan, and the results indicated that both independent and two-stage decision-making models generated very similar conclusions. We also found that gender difference contributed to reduce cigarette consumption. In addition, this study indicated that high-income smokers were less likely to switch brands, whereas well-educated smokers were more likely to switch brands. Most importantly, we questioned the effectiveness of cigarette tax policy, as our results suggested that higher price did not necessarily reduce consumption. Indeed, data indicated that <24 % of smokers actually reduced their cigarette consumption after the tax on cigarettes increased.
我们研究了香烟税对烟草消费的影响,重点关注吸烟者在减少香烟消费和更换品牌之间的选择。我们构建了三个基于情景的模型来研究以下两个主题:(1)决定是否减少香烟消费与进行品牌转换(同时或先后进行)之间的关系;(2)在面临更高税收时,影响吸烟者在消费和品牌转换方面决策的关键决定因素。我们应用了从台湾一项调查中收集的数据,结果表明独立决策模型和两阶段决策模型得出了非常相似的结论。我们还发现性别差异有助于减少香烟消费。此外,本研究表明高收入吸烟者更换品牌的可能性较小,而受过良好教育的吸烟者更换品牌的可能性较大。最重要的是,我们对香烟税政策的有效性提出了质疑,因为我们的结果表明价格上涨不一定会减少消费。事实上,数据显示在香烟税提高后,实际减少香烟消费的吸烟者不到24%。
