The introduction of lower strength alcohol products results in less absolute alcohol purchased. This paper estimates the potential impact of price in shifting British household purchases from higher to lower strength beers and ciders.
Descriptive statistics and controlled interrupted time series analyses using Kantar Worldpanel's British household purchase data from 70,303 households during 2015-2018 and the first half of 2020.
No and low-alcohol products were less likely to be on price promotion than higher strength products. No and low-alcohol beers were cheaper per volume than higher strength beers; the reverse was the case for ciders. With the exception of low strength ciders (which had very few purchases) a higher volume was purchased when the product was on price promotion than when not. Again, with the exception of low strength ciders, the cheaper the cost, the greater the volume of purchase, more so when the product was on price promotion. The introduction of minimum unit price in Scotland (when controlling for changes in Northern England) and in Wales (when controlling for changes in Western England) shifted purchases from higher to lower strength products, more so for ciders than beers. In relative terms, the alcohol by volume of beer dropped by 2% and of cider by 7%. Changes did not differ by household income or the age of the main shopper.
There are opportunities for governments and alcohol producers and retailers to facilitate shifts of purchases from higher to lower alcohol strength products. Alcohol producers and retailers can ensure that the price of lower strength products is competitive vis a vis higher strength products. Governments can introduce minimum unit prices for the sale of alcohol, as has been done in Scotland and Wales.

低酒精度产品的引入会导致购买的绝对酒精量减少。本文旨在评估价格变化对英国家庭从高酒精度啤酒和苹果酒转向低酒精度啤酒和苹果酒购买的潜在影响。
使用 Kantar Worldpanel 2015-2018 年和 2020 年上半年期间 70303 户英国家庭的购买数据，进行描述性统计和受控中断时间序列分析。
无酒精和低酒精产品的促销频率低于高酒精度产品。无酒精和低酒精啤酒的单位体积价格低于高酒精度啤酒；苹果酒则相反。除了低酒精度苹果酒（购买量很少）之外，促销时的购买量通常高于非促销时的购买量。同样，除了低酒精度苹果酒之外，价格越低，购买量越大，促销时更为明显。苏格兰（控制英格兰北部变化）和威尔士（控制英格兰西部变化）引入最低单位价格后，高酒精度产品的购买量向低酒精度产品转移，苹果酒的转移量高于啤酒。从相对角度来看，啤酒的酒精度下降了 2%，苹果酒下降了 7%。变化与家庭收入或主要购物者的年龄无关。
政府、酒精生产商和零售商有机会促进从高酒精度产品向低酒精度产品的购买转移。酒精生产商和零售商可以确保低酒精度产品的价格相对于高酒精度产品具有竞争力。政府可以像苏格兰和威尔士那样，引入酒精销售的最低单位价格。
