^aRelative change in the difference of the HN food consumption share between high-SES and low-SES populations.
^bFractional increase in average firm R&D investment in HN food.
^c Columns in italics (“No FB”) report counterfactual “no feedback” outcomes. Their simulations are identical to those for “Equilibrium” except that the feedbacks involving product category exposure affecting Category Consideration and product category consumption affecting Systems & Institutions have been deactivated.
^dIncludes also temporary, 5-year-lasting, 2a2 + 2b1 + 2b2 campaigns.
^eIncludes permanent 2a2 + 2b1 + 2b2 campaigns.
