The Pass-Through of the Largest Tax on Sugar-Sweetened Beverages: The Case of Boulder, Colorado
We estimate the incidence of a relatively new type of excise tax, a tax on sugar-sweetened beverages (SSBs). We examine the largest such tax to date, which is two cents per ounce, in Boulder, CO. Using data that were hand-collected from stores and restaurants in both Boulder and two control communities, as well as internet data of restaurant menus, we find that the tax was largely, but not completely, passed through to consumers 5-7 weeks after implementation. Some retailers add the tax only at the register, indicating that estimates solely from posted prices would result in an underestimate of pass-through.
