Companies' Shrinkflation Tactics Highlighted by Consumer Research

A range of consumer‑goods firms are reducing product sizes, ingredient quantities, or overall content while keeping prices unchanged, a trend known as shrinkflation. Examples shared on Reddit include a U.S. quart of milk that holds only three cups, an Australian Domino’s large pizza that barely fits a personal size, and a Mars bar with a largely empty wrapper. Academic research published in the Journal of Consumer Research shows that shoppers find hidden quality cuts—sometimes called skimpflation—particularly unfair. The study reports that consumers rate quality reductions as less fair than price hikes or size reductions and are less likely to repurchase such items. One participant noted, “For me, a change in the quality or composition of a product means that it’s essentially a different product.” The researchers also found that transparent communication about quality changes lessens negative reactions, suggesting that clear labeling could help consumers make more informed decisions.

The findings raise questions for consumer‑protection policy, which may need to address hidden quality declines in addition to traditional price and size inflation. Shoppers are advised to compare ingredient lists, read reviews, and consider alternative brands when faced with suspected skimpflation.
