“Grocery stores study when people go shopping the most. And so you might be able to see a price go down one day and then go up another day,” Aguilar told The Associated Press.Researchers say those fears are misplaced. A study published in late May found “virtually no surge pricing” before or after electronic shelf labels were adopted. The study was authored by Ioannis Stamatopoulos of the University of Texas, Austin, Robert Evan Sanders of the University of California, San Diego and Robert Bray of Northwestern University

The researchers looked at prices between 2019 and 2024 at an unnamed grocery chain than began using digital labels in October 2022. They found that temporary price increases affected 0.005% of products on any given day before electronic shelf labels were introduced, a share that increased by only 0.0006 percentage points after digital labels were installed.The study also determined that discounts were slightly more common after digital labels were introduced.Economists have long wondered why grocery prices don’t change more often, according to Stamatopoulos. If bananas are about to expire, for example, it makes sense to lower the price on them. He said the cost of having workers change prices by hand could be one issue.

But there’s another reason: Shoppers watch grocery prices closely, and stores don’t want to risk angering them.“Selling groceries is not selling a couch. It’s not a one-time transaction and you will never see them again,” Stamatopoulos said. “You want them coming to the store every week.”

Electronic price labels aren’t new. They’ve been in use for more than a decade at groceries in Europe and some U.S. retailers, like Kohl’s.

But they’ve been slow to migrate to U.S. grocery stores. Only around 5% to 10% of U.S. supermarkets now have electronic labels, compared to 80% in Europe, said Amanda Oren, vice president of industry strategy for North American grocery at Relex Solutions, a technology company that helps retailers forecast demand.Earlier this year actor Sydney Sweeney paid homage to Novak on the Met Gala red carpet. She’s portraying Novak in a new film directed by Colman Domingo about her relationship with Rat Packer Sammy Davis Jr.

Of this latest honor, Novak said she is “deeply touched” to receive the award.“To be recognized for my body of work at this time in my life is a dream come true,” Novak said. “I will treasure every moment I spend in Venice. It will fill my heart with joy.”
