Evidence shows that price is an important policy lever in reducing consumption of alcohol and tobacco. However, there is little evidence of the cross-price effect between alcohol and tobacco.
This paper uses an econometric model which estimates participation and consumption elasticities, on data from the UK Living Costs and Food Survey 2006-2017 and extends the literature by, for the first time, estimating joint price elasticities for disaggregated alcohol and tobacco products. This paper presents new price elasticities and compares them to the existing literature.
The own-price elasticity estimates are all negative for both participation and consumption. There is no pattern to the estimates of cross-price elasticities. The elasticity estimates, when used in the Sheffield Tobacco and Alcohol Policy Model, produce bigger changes in consumption for the same change in price compared to other elasticity estimates in the existing literature.
Consumption of alcohol and tobacco are affected by the prices of one another. Policymakers should bear this in mind when devising alcohol or tobacco pricing policies.
有证据表明，价格是减少酒精和烟草消费的重要政策杠杆。然而，关于酒精和烟草之间的交叉价格效应的证据很少。
本文使用计量经济学模型，根据英国生活成本和食品调查 2006-2017 年的数据估计参与和消费弹性，并首次估计了酒精和烟草产品的细分联合价格弹性，扩展了文献。本文提出了新的价格弹性，并将其与现有文献进行了比较。
参与和消费的自有价格弹性估计均为负。交叉价格弹性的估计没有规律。当用于谢菲尔德烟草和酒精政策模型时，与现有文献中的其他弹性估计相比，相同价格变化会导致消费的更大变化。
酒精和烟草的消费受到彼此价格的影响。政策制定者在制定酒精或烟草定价政策时应考虑到这一点。
