Description
Schlender, Rieger, and Eggert test in a paper published in 2024 whether grocery shopping fits a classic foraging model from animal study. The model says gains grow toward a cap as time in a patch rises, so shoppers should leave at a set point. Stores are dense patches, unlike wild settings.
The team interviewed 61 shoppers at a German supermarket about their current trip. A curved model tied time in store to money gained and fit the data well. Long trip data were sparse, which left the cap value unsure. Still, the match backs the idea that foraging theory can model human shopping, even from self reports.
