Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price.
This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic characteristics, smokers' exposure to antismoking messaging, health warning labels and tobacco marketing.
Generalised estimating equations were employed to analyse the association between the price ratio of two different cigarette forms and the usage of one form over the other.
A 10% increase in the relative price ratio of legal to RYO cigarettes is associated with a 4.6% increase in the probability of consuming RYO cigarettes over manufactured legal cigarettes (p≤0.05). In addition, more exposure to antismoking messaging is associated with a lower odds of choosing RYO cigarettes over manufactured legal cigarettes (p≤0.05). Non-significant associations exist between the manufactured illegal to legal cigarette price ratios and choosing manufactured illegal cigarettes, suggesting that smokers do not switch to manufactured illegal cigarettes as prices of legal ones increase. However, these non-significant findings may be due to lack of variation in the price ratio measures. To improve the effectiveness of increased taxes and prices in reducing smoking, policymakers need to narrow price variability in the tobacco market. Moreover, increasing antismoking messaging reduces tax avoidance in the form of switching to cheaper RYO cigarettes in Uruguay.
关于吸烟者是否会因相对价格变化而转向非法卷烟或自卷烟的研究较少。
本文探讨在控制协变量(包括社会人口特征、吸烟者接触反吸烟信息、健康警示标签和烟草营销)之后,三种卷烟形式(合法制造卷烟、非法制造卷烟和自卷烟)之间的相对价格如何与一种形式相对于另一种形式的选择相关联。
采用广义估计方程分析两种不同卷烟形式的价格比与一种形式相对于另一种形式的使用之间的关联。
合法卷烟与自卷烟的相对价格比提高10%,会使消费自卷烟而非合法制造卷烟的概率增加4.6%(p≤0.05)。此外,更多地接触反吸烟信息与选择自卷烟而非合法制造卷烟的几率较低相关(p≤0.05)。非法制造卷烟与合法卷烟的价格比和选择非法制造卷烟之间存在不显著的关联,这表明随着合法卷烟价格上涨,吸烟者不会转向非法制造卷烟。然而,这些不显著的结果可能是由于价格比测量缺乏变化所致。为提高提高税收和价格在减少吸烟方面的有效性,政策制定者需要缩小烟草市场的价格差异。此外,在乌拉圭,增加反吸烟信息可减少以转向更便宜的自卷烟形式的避税行为。
