To explore how advertising affects demand for cigarettes and potential substitutes, including snus, dissolvable tobacco, and medicinal nicotine.
A Web-based experiment randomized 1062 smokers to see advertisements for alternative nicotine products or soft drinks, then complete a series of purchase tasks, which were used to estimate demand elasticity, peak consumption, and cross-price elasticity (CPE) for tobacco products.
Lower demand elasticity and greater peak consumption were seen for cigarettes compared to all alternative products (p < .05). CPE did not differ across the alternative products (p ≤ .03). Seeing relevant advertisements was not significantly related to demand.
These findings suggest significantly lower demand for alternative nicotine sources among smokers than previously revealed.
探讨广告如何影响香烟及潜在替代品(包括口含烟、可溶解烟草和药用尼古丁)的需求。
一项基于网络的实验将1062名吸烟者随机分组,使其观看替代尼古丁产品或软饮料的广告,然后完成一系列购买任务,这些任务用于估计烟草产品的需求弹性、峰值消费量和交叉价格弹性(CPE)。
与所有替代产品相比,香烟的需求弹性更低,峰值消费量更高(p < .05)。替代产品之间的CPE没有差异(p ≤ .03)。观看相关广告与需求没有显著关联。
这些研究结果表明,吸烟者对替代尼古丁来源的需求显著低于此前所揭示的情况。
