An Analysis of Beverage Size Restrictions
用非线性定价模型分析纽约市“汽水禁令”式的饮料容量限制，发现除极严格限制外，消费者福利不受影响，但卖家利润下降，总消费量减少且幅度因消费者群体而异。
Due to high levels of obesity, various government interventions have been proposed to curb the consumption of sugar‐sweetened beverages (SSBs). The New York City “soda ban,” which proposed to limit the size of SSBs is among the most well‐known and controversial. While public debates about beverage‐size‐restrictions tend to focus on how consumers are impacted, we use a nonlinear pricing model to show that, for all but extremely tight restrictions, consumer welfare would be unaffected by an enforceable restriction. However, sellers’ profit would decline. While consumption is predicted to decline overall, the magnitude of the decline will vary by consumer segment.
