This paper estimates the changes in energy, fat, and sodium purchases resulting from a tax that increases sugar-sweetened beverage (SSB) prices by 20 percent as well as the effect of such a tax on body weight. Researchers found that a 20 percent price increase on SSBs would result in a decrease in energy purchased in stores of 24.3 calories 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 over 10 years. Substitution from SSBs to other beverages was limited and only involved fruit juices. There was no evidence of substitution to sugary foods, and there was a decrease in calories from complementary foods (i.e., ice cream, salty snacks).
Implications of a Sugar-Sweetened Beverage (SSB) Tax When Substitutions to Non-Beverage Items are Considered
Predicting the Effects of Sugar-Sweetened Beverage Taxes on Food and Beverage Demand in a Large Demand System
This paper predicts the effects of sugar-sweetened beverage (SSB) taxes on demand for 23 categories of packaged foods and beverages and the associated changes in calories, fat, and sodium intake and consumer welfare. Using household food purchase data from the national 2006 Nielsen Homescan panel, researchers used demand elasticity estimates … More
This article examines the health and financial impact of a tax on sugar-sweetened beverages (SSBs) on higher- and lower-income households. Using data from the 2006 Nielsen Homescan panel, researchers found that large taxes on SSBs have the potential to positively influence weight outcomes, especially for middle-income households. A 40 percent … More
Examining Higher and Lower Income Household Food Purchasing Behavior and Whether It May Be Responsible for Childhood Obesity
This project will examine the extent to which household food purchasing behavior differs between higher- and lower-income households and whether these differences may be partly responsible for socioeconomic differences in childhood obesity. In addition, investigators will use econometric models of household food purchases to simulate the extent to which pricing … More
