This study examines how the change in serving sizes in Nutrition Facts Panel (NFP) affects consumer choices by developing and estimating an equilibrium model of both consumer demand and firms’ pricing and nutritional choices decisions, using carbonated soft drinks (CSD) as a case study. Our study found that larger serving sizes and corresponding nutritional changes negatively impacted consumer demand. Counterfactual simulations explored the effects of different serving size regulations, showing a preference shift towards smaller bottle sizes, and potentially healthier alternatives, and industry adaptations through unnoticed product reformulations. These findings suggest that strategic serving size adjustments policies and product reformulations from food manufacturers may support healthier consumer choices.
