> If consumers were the rational creatures depicted in classic economic theory, they would notice shrinkflation. They would keep their eyes on the price per Cocoa Puff and not fall for gimmicks in how companies package those Cocoa Puffs.
It’s not that consumers are not rational. Optimizing around 1 oz change of coco puffs isn’t really a good return on investment for many people.Certainly people with limited budgets or fixed incomes might notice the change and adjust.
However if you are running to the store after dropping you kid off at soccer practice and only have 30 min to shop you care more about time than the small amount of money they are “up charging”.
Besides, people might be in-elastic with regards to their brands. Certainly I could switch to another cereal but if I want coco puffs I’ll pay the premium because lucky charms won’t substitute.
