在这篇文章中，我们研究了美国家庭对常规碳酸甜饮料（CSB）和啤酒需求的习惯强度的异质性。一个需求模型，嵌套一个平滑的过渡函数被用来描述习惯为基础的消费模式，揭示异质性的家庭之间的习惯的优势。我们发现，那些对特定产品有强烈偏好的习惯性消费者，对价格或支出的敏感度不如总人口。这一发现得到了苏打水和啤酒税潜在影响的模拟的进一步支持。我们发现，苏打水和啤酒税的总响应小于当习惯的影响被假定为同质的。
In this article, we study the heterogeneity of habit strength in households' demand for regular carbonated sweetened beverages (CSBs) and beer in the United States. A demand model that nests a smooth transition function is used to describe habit-based consumption patterns, revealing heterogeneous strengths of habits among households. We find that more habitual consumers, those with a strong preference for a particular product, are not as sensitive to price or expenditure as the aggregate population. This finding is further supported by simulations of the potential effects of soda and beer taxes. We find the aggregate response to soda and beer taxes is smaller than when the influence of habit is assumed to be homogeneous.
