This study assessed the extent to which the elasticity of cigarette and waterpipe tobacco products differs between men and women. We also explored the levels of substitution and complementarity in tobacco products among men and women.
The study examines tobacco elasticities in three Arab countries: Lebanon, Jordan and the West Bank of Palestine.
We used data from nationally representative surveys of adults aged ≥18 years in Lebanon (n=1680), Jordan (n=1925) and Palestine (n=1679). The proportion of women was 50.0% of the sample in Lebanon and Palestine, and 44.6% in Jordan.
A zero-inflated Poisson regression model estimated own-price and cross-price elasticities for two variations of cigarettes and five variations of waterpipe tobacco products. Elasticities were measured based on eight scenarios of prices.
Demand for waterpipe tobacco products was elastic for both men and women. The cross-price elasticities in the three countries indicate the existence of substitution between cigarettes and waterpipe products and by different varieties within each of the two tobacco products. Gender differences varied across the three countries whereby higher cross-price elasticities were observed for women in Jordan and Palestine. For example, the price elasticity for discount waterpipe was -1.4 and -0.6 for women and men in Jordan, respectively.
Results on the elasticity of demand for tobacco products and the existence of substitution between tobacco products reveal the higher responsiveness of men and women to changes in tobacco prices. This should be taken into consideration in tobacco control strategies particularly when reducing tobacco consumption via taxation policies.
本研究评估了男性和女性对香烟和水烟烟草产品弹性的差异程度。我们还探讨了男性和女性对烟草产品的替代和互补程度。
该研究考察了三个阿拉伯国家(黎巴嫩、约旦和巴勒斯坦西岸)的烟草弹性。
我们使用了来自黎巴嫩(n=1680)、约旦(n=1925)和巴勒斯坦(n=1679)的成年人年龄≥18 岁的全国代表性调查数据。黎巴嫩和巴勒斯坦样本中女性的比例为 50.0%,约旦为 44.6%。
零膨胀泊松回归模型估计了两种香烟变体和五种水烟烟草产品变体的自价和交叉价格弹性。弹性是基于八种价格情景来衡量的。
水烟烟草产品的需求对男性和女性都是有弹性的。这三个国家的交叉价格弹性表明,香烟和水烟产品之间存在替代关系,并且两种烟草产品中的每种产品的不同品种之间也存在替代关系。性别差异在三个国家中有所不同,约旦和巴勒斯坦的女性交叉价格弹性较高。例如,在约旦,折扣水烟的价格弹性分别为女性-1.4 和男性-0.6。
关于烟草产品需求弹性和烟草产品之间替代关系的结果表明,男性和女性对烟草价格变化的反应更为敏感。在制定烟草控制战略时,特别是在通过税收政策减少烟草消费时,应考虑到这一点。
