Summary
This research article investigates the relationship between extreme temperatures and the purchasing behavior of sugary drinks in the United States. It utilizes a nationally representative consumer panel and daily weather data to analyze how extreme heat influences the volume of sugary drinks purchased. The study finds that higher temperatures lead to increased purchases of sugary drinks, particularly when temperatures exceed 95°F (35°C). The research also examines various factors that may drive this behavior, including changes in shopping habits and psychological biases. It highlights that urban households and those with members in outdoor occupations are more affected by extreme heat. Additionally, the study assesses the role of retailers in price adjustments during heat events and finds no significant evidence of such adjustments for sugary drinks. The findings contribute to understanding dietary patterns in the context of climate change and emphasize the need for policies promoting healthier consumption habits.
