We study the impact of a hypothetical tax on sugar - sweetened beverages (SSB) on the US households’ nutrients purchase, welfare change, and health benefit. Differently from the traditional approach, Food at Home (FAH) is here defined as a “home” good instead than a market good. The model is estimated by using an incomplete approximate Exact Affine Stone Index demand system on US consumer expenditure and time use data. The results show that a SSB tax would be much more effective in decreasing household nutrients purchase than it would appear by estimating a model neglecting time costs in home food production. A tax induced increased in SSB price by 20% is predicted to decrease the per capita energy purchase by 29.17 kcal/day. The health benefits of the tax, measured only in terms of reduced medical expenditure, would overcome estimated welfare losses by more than $1000 million.
