In brief
Purpose: To assess the impact of taxes, warnings, and a combination of taxes and warnings on US adults' decisions to purchase products that contain red meat in an online grocery store. Procedures (methods): Participants will be recruited from Prime Panels (an online panel research company). Following online consent, participants will be assigned to one of four trial arms: 1) Control (no warning and no tax), 2) Warnings (all products that contain red meat have a health warning and environmental warning), 3) Tax (30% tax on products that contain red meat), and 4) Combined warning and tax (all products that contain red meat will have the two warnings and a 30% tax). Then, participant will enter an online grocery store reflecting their assigned arm. The participant will be instructed to complete a shopping task in the online grocery store. After completing the shopping task, participants will be redirected to an online survey and answer a series of questions about the shopping task, labels (excluding tax and control groups), and taxes (excluding warning and control groups). Questions will also include standard demographic and health related variables.
