The purpose of this study is to conduct a discrete choice experiment to investigate whether warning labels on Sugar-Sweetened Beverages (SSBs) alter the effectiveness of a tax on SSBs, especially among parents who are Black, Latinx and lower income. The research team will conduct an online choice experiment with 2,700 parents and caregivers of children who are 5 years old or younger. Participants will be assigned to one of three SSB warning label conditions (no label, text-only label, and icon label) and will be asked a series of 8 choice questions where they must choose between different beverages as their prices are varied through the addition of different tax rates. Specific aims include: (1) estimate the sensitivity to changes in SSB prices of parents’ purchases of SSBs for young children; (2) determine the effect of two different warning labels on parents’ purchases of SSBs and perceptions of these beverages; (3) assess whether warning labels make parents more or less sensitive to changes in SSB price; and (4) evaluate how these effects differ across income and racial/ethnic groups (especially for parents who are Black and Latinx).

Sweetened beverage taxes: Economic benefits and costs according to household income

Taxing sweetened beverages has emerged as an important and effective policy for addressing their overconsumption. However, taxes may place a greater economic burden on people with lower incomes. We assess the degree to which sweetened beverage taxes in three large U.S. cities placed an inequitable burden on populations with lower incomes by assessing spending on More
