Do high vs. low purchasers respond differently to a nonessential energy-dense food tax? Two-year evaluation of Mexico's 8% nonessential food tax.

ABSTRACT: It is unclear whether response to a nonessential food tax varies across time or for high vs. low-consuming households. The objective is to examine whether the effect of Mexico's 2014 8% nonessential energy-dense foods tax increased in the second year post-implementation and whether it differentially affected households by pre-tax purchasing pattern. We used longitudinal data on Mexican household food purchases (n=6089 households) from 2012 to 2015. Households were classified based on median pre-tax purchases: low untaxed/low taxed ("low"), low untaxed/high taxed ("unhealthy"), high untaxed/low taxed ("healthy"), and high untaxed/high taxed ("high") purchasers. Fixed effects models tested whether observed post-tax purchases differed from the counterfactual, or what would have been expected
