Do rising grocery prices make you think the economy is getting worse for you?

A Michigan State University study analyzing 40 years of data found that restaurant menu price increases raise one-year inflation expectations more immediately than grocery price increases. The restaurant effect mostly disappears within a month, while the grocery effect lasts about three months.

Why it matters

Food prices shape how Americans view future inflation because consumers encounter them weekly or more often, a frequency that gives them more influence than costs such as rent. Understanding which price changes stick in consumers' minds helps explain why inflation expectations can persist even when headline numbers move.

The study covers 40 years of data, and food makes up around 13% of U.S. household spending, the third-largest expenditure behind housing and transportation. Grocery prices are roughly 2% above a year ago and 30% above 2020 levels, but the exact shares attributable to inflation expectations remain unquantified in the extraction.

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

Researchers examined how consumers experience food prices at grocery stores and restaurants and how those experiences shape expectations for future price increases. The findings indicate that the timing of a price change, not just its size, determines how long it influences what households expect inflation to do next.

Restaurant menu price effects on inflation expectations mostly disappear within a month.
Grocery price effects on inflation expectations last about three months.
Grocery prices were roughly 2% higher than a year earlier.

Inflation Landscape

The Bureau of Labor Statistics tracks food-at-home and food-away-from-home prices as separate components of the Consumer Price Index. This study suggests those two series may shape household inflation expectations on very different timelines.

Grocery price increases tend to shape household inflation expectations for about three months, which can influence how families plan weekly budgets. Restaurant price increases fade from consumer expectations much faster, so dining-out costs may affect outlook less durably than what appears on grocery receipts.

The takeaway

Pay attention to grocery price trends when judging where inflation is headed, since those increases tend to linger in consumer expectations longer than restaurant menu changes. Households can use that pattern to time major purchases and budget adjustments.
