在对含糖饮料征收每升1比索消费税的第一年，墨西哥的含糖饮料购买量减少了6%。本文估计了税后两年饮料采购的变化。我们使用了2012年1月至2015年12月6645户家庭的家庭商店购买数据。税后年份的税收和免税饮料的购买量变化使用两个独立的模型进行估计：将2014年与基于税前（2012-2013）趋势的预测量（反事实）进行比较，并将2015年与相同的反事实进行比较。两年来，含税饮料的购买量平均下降了8.2%（2014年-5.5%，2015年-9.7%）。在这两年中，社会经济地位最低的群体在饮料税上的降幅最大。税后期间，未征税饮料的购买量增长了2.1%。在墨西哥，受税饮料的购买量持续下降，并在征税的第二年有所增长。
In the first year of a 1 peso per liter excise tax on sugar-sweetened beverages, there was a 6% reduction in purchases of taxed beverages in Mexico. This paper estimates changes in beverage purchases two years after tax implementation. We used household store purchase data for 6,645 households from January 2012 to December 2015. Changes in purchases of taxed and untaxed beverages in the post-tax years were estimated using two separate models: comparing 2014 with predicted volumes (counterfactual) based on pre-tax (2012-2013) trends, and comparing 2015 with the same counterfactual. Purchases of taxed beverages decreased by 8.2% over the two years on average (-5.5% in 2014; -9.7% in 2015). The lowest socioeconomic group had the largest decreases in taxed beverages in both years. Untaxed beverage purchases increased 2.1% in the post-tax period. In Mexico, lower purchases of taxed beverages was sustained and grew in the second year of the tax.
