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 policies, such as taxes on specific obesity-promoting foods, could effectively promote healthier food purchases. The results of this analysis will provide policy makers with additional information concerning how food price changes (via government policy or market forces) influence food expenditure and consumption patterns for higher- and lower-income households. This research will be conducted using the Nielsen Company’s Homescan longitudinal dataset of household weekly at-home food expenditures, which contains detailed data on the quantity and price of specific home food purchases.
Examining Higher and Lower Income Household Food Purchasing Behavior and Whether It May Be Responsible for Childhood Obesity
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
Implications of a Sugar-Sweetened Beverage (SSB) Tax When Substitutions to Non-Beverage Items are Considered
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 … 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
