使用2006年的Homescan面板，我们估计了将含糖饮料(SSB)的价格提高20%的税收导致的能量、脂肪和钠购买量的变化，以及这种税收对体重的影响。除了其他饮料可能出现的替代外，我们还考虑了SSB和12种主要食品类别之间的替代。我们的主要发现是，这项税收将导致每人每天从商店购买的能量减少24.3千卡，这将转化为第一年平均减肥1.6磅，长期累积减肥2.9磅。我们没有发现替代含糖食物的证据，并表明补充食物可能有助于减少能量消耗。尽管价格弹性显著降低，但对于最大的SSB购买者来说，这项税收对卡路里的影响类似。(C)2012爱思唯尔B.V.保留所有权利。
Using the 2006 Homescan panel, we estimate the changes in energy, fat and sodium purchases resulting from a tax that increases the price of sugar-sweetened beverages (SSBs) by 20% and the effect of such a tax on body weight. In addition to substitutions that may arise with other beverages, we account for substitutions between SSBs and 12 major food categories. Our main findings are that the tax would result in a decrease in store-bought energy of 24.3 kcal per day per person, which would translate into an average weight loss of 1.6 pounds during the first year and a cumulated weight loss of 2.9 pounds in the long run. We do not find evidence of substitution to sugary foods and show that complementary foods could contribute to decreasing energy purchases. Despite their significantly lower price elasticity, the tax has a similar effect on calories for the largest purchasers of SSBs. (C) 2012 Elsevier B.V. All rights reserved.
