Abstract
We study the impact of a hypothetical tax on sugar - sweetened beverages (SSBs) on the U.S. 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 of a market good and consumers’ demands derived under the
assumption that households maximize utility subject to both a money and a time constraint. The model is
estimated by using an incomplete approximate Exact Affine Stone Index (EASI) demand system on a data set
built by merging the U.S. consumer expenditure and time use surveys. 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, due to a lesser compensation of calories from increasing FAH
consumption. A tax-induced 38% increase in SSB price is predicted to decrease the per capita energy purchase by
41 kcal/day
