有人提议对含糖饮料征税以对抗肥胖。利用州苏打水销售税数据和儿童个人数据，我们研究了小额税收是否可能改变消费和体重增加，或者是否需要更大幅度的增税。我们发现，现有的汽水税（杂货店的汽水税通常不高于 4%）不会对汽水消费的总体水平或肥胖率产生实质性影响。然而，我们确实发现，高危儿童亚群——已经超重的儿童、来自低收入家庭的儿童或非裔美国人——可能比其他人对汽水税更敏感，尤其是当学校提供汽水时。这些小额税收的更大影响可能来自于将其产生的收入用于其他肥胖预防工作，而不是直接影响消费。
Taxes on sugar-sweetened beverages have been proposed to combat obesity. Using data on state sales taxes for soda and individual-level data on children, we examine whether small taxes are likely to change consumption and weight gain or whether larger tax increases would be needed. We find that existing taxes on soda, which are typically not much higher than 4 percent in grocery stores, do not substantially affect overall levels of soda consumption or obesity rates. We do find, however, that subgroups of at-risk children-children who are already overweight, come from low-income families, or are African American-may be more sensitive than others to soda taxes, especially when soda is available at school. A greater impact of these small taxes could come from the dedication of the revenues they generate to other obesity prevention efforts rather than through their direct effect on consumption.
