We measure the effect of a large nationwide tax reform on sugar-added drinks and caloric-dense food introduced in Mexico in 2014. Using scanner data containing weekly purchases of 47,973 barcodes by 8,130 households and an RD design, we find that calories purchased from taxed drinks and taxed food decreased respectively by 2.7% and 3%. However, this was compensated by increases from untaxed categories, such that total calories purchased did not change. We find increases in cholesterol (12.6%), sodium (5.8%), saturated fat (3.1%), carbohydrates (2%), and proteins (3.8%).
我们衡量了 2014 年墨西哥全国范围内的一项大型税收改革对含糖饮料和高热量食品的影响。我们使用包含 8130 户家庭每周购买的 47973 个条形码的扫描器数据和 RD 设计，发现来自征税饮料和征税食品的卡路里摄入量分别下降了 2.7%和 3%。然而，这被未征税类别的增加所抵消，因此总卡路里摄入量没有变化。我们发现胆固醇（12.6%）、钠（5.8%）、饱和脂肪（3.1%）、碳水化合物（2%）和蛋白质（3.8%）的摄入量有所增加。
