Do rising grocery prices make you think the economy is getting worse for you?
A Michigan State University study of 40 years of data found that restaurant menu price increases shape consumers' one-year inflation expectations more immediately than grocery price increases, but the restaurant effect mostly fades within a month. For U.S. operators in food-service and grocery categories, this bears on how price changes are communicated and how quickly customer sentiment about inflation may shift.
Why it matters
Food makes up around 13% of U.S. household spending, and consumers encounter food prices weekly or more often, which gives them outsized influence on how they judge inflation. Restaurant pricing moves expectations quickly but briefly, while grocery pricing creates a longer-lasting impression that can shape spending behavior for months.
The study covered 40 years of data, with food accounting for about 13% of U.S. household spending, the third-largest category behind housing and transportation. Grocery prices are roughly 2% above year-ago levels but 30% above 2020 levels, the comparison that shapes longer-run consumer perceptions.
The players
Michigan State University
A public research university in East Lansing, Michigan, whose researchers conducted the study on food prices and consumer inflation expectations.
The details
Consumers form inflation views partly from prices they encounter often, and food is one of the few costs they see weekly or more frequently. The study found restaurant menu increases move one-year expectations quickly, but that effect largely dissipates within a month. Grocery increases carry more staying power, with the effect on expectations persisting roughly three months. For operators, this suggests that the timing and visibility of a price change can matter as much as its size.
Timeline
Restaurant menu price effects on inflation expectations mostly disappear within a month.
Grocery price effects on inflation expectations last about three months.
Market Landscape
Research on consumer inflation expectations has increasingly focused on which prices households observe most often, with food serving as a frequent reference point. This study adds evidence that grocery pricing carries more persistent influence on inflation views than restaurant pricing.
Operators in grocery and food-service should plan price communications with timing in mind, since restaurant price changes fade quickly from customer inflation perceptions while grocery increases linger. Review how frequently you adjust menu and shelf prices, as perceived inflation may affect customer traffic and spending.
The takeaway
Track how your customers respond to price changes in the grocery and menu categories you sell, since the perception window differs by price type. Consider the study's findings when planning the timing of any future price adjustments.
