Consumption of sugar sweetened beverages exhibits strong associations with weight gain, obesity, and dental caries, especially in young children. The aim of this article is to estimate price elasticities for parents' sugar-sweetened beverages consumption choices with respect to their pre-school children and to estimate elasticities with respect to nutritional attribute labels across sugar-sweetened beverages. Our results show that 1% increase in the price of fizzy drink, juice and cordial would reduce pre-school children's consumption of each drink by 0.80%, 0.51%, and 0.34% respectively. Such price effects on children's consumption do not substantially differ between high and low-income respondents but the effect on the children's Fizzy Drink consumption is significantly larger for respondents from large households than those from small households and are significantly lower than the price effects on the consumption of the rest of the family for Juice and Cordial. The marginal effects of demand with respect to nutritional attribute labels of sugar-sweetened beverages matter for Juice and Cordial, and are strongest for low-income families; however, these effects do not substantially differ between large and small-household respondents.

父母对学龄前儿童含糖饮料的需求：来自特定偏好实验的证据

含糖饮料的消费与体重增加、肥胖和龋齿密切相关，尤其是在幼儿中。本文的目的是估计父母对学龄前儿童的含糖饮料消费选择的价格弹性，并估计含糖饮料的营养属性标签的弹性。我们的研究结果表明，汽水、果汁和甜酒的价格每上涨 1%，学龄前儿童对每种饮料的消费量将分别减少 0.80%、0.51% 和 0.34%。这种价格对儿童消费的影响在高收入和低收入受访者之间没有显着差异，但对儿童消费的影响 s 来自大家庭的受访者的 Fizzy Drink 消费量明显高于来自小家庭的受访者，并且显着低于价格对其他家庭成员对 Juice 和 Cordial 消费的影响。需求对含糖饮料营养属性标签的边际效应对果汁和甜酒很重要，对低收入家庭影响最大；然而，这些影响在大家庭和小家庭受访者之间没有显着差异。
