Globally, more than 45 countries have implemented sugar-sweetened beverage (SSB) taxes; however, little is known about effects on marketing practices. For the 2017 Oakland, California, 1 cent per ounce SSB tax, this study evaluated long-term changes in beverage price promotions, depth of sale, and interior and exterior advertising at stores, collected via in-person audits at two time points (pre-tax and 24-months post-tax). Overall, based on difference-in-differences estimation, relative to the comparison site, no significant pre-post tax changes were found in the odds of price promotions, exterior or interior advertising, or sale depth for SSBs or untaxed beverages. As additional SSB taxes are considered these findings suggest that SSB taxes may not have long-term effects on store marketing practices.
全球有超过 45 个国家实施了含糖饮料（SSB）税；然而，对于这些税收对营销实践的影响却知之甚少。本研究评估了 2017 年加利福尼亚州奥克兰市每盎司 1 美分 SSB 税实施后，商店中饮料价格促销、销售深度以及内部和外部广告的长期变化情况，这些数据是通过在两个时间点（征税前和征税后 24 个月）进行的实地审计收集的。总体而言，基于差异中的差异估计，与比较地点相比，SSB 和未征税饮料的价格促销、外部或内部广告或销售深度的出现概率在征税前后没有显著变化。随着更多 SSB 税的考虑，这些发现表明 SSB 税可能不会对商店的营销实践产生长期影响。
