Clinical Trial Summary

The goal of this randomised controlled trial is to compare taxation with subsidies to encourage healthier food choices in the out-of-home food sector. Participants will be asked to make hypothetical food choices in an online simulation study of a delivery app. Participants will be randomised into four different intervention groups:

1. Price reduction (10%) on healthier foods

2. Price increase (10%) to less healthy foods

3. A combination of price reduction to healthier foods and price increase to less healthy foods

4. Existing price structure (i.e. control group)

The investigators will further examine effectiveness of these fiscal policies on healthy eating by socioeconomic position to understand whether these policies are equitable.
