Displaying and discounting perishables: impact on retail profits and waste
Perishable products constitute about 30% of total grocery store sales and 56% of store waste. Empirical studies have shown that consumers' purchasing behavior depends on how products of different freshness levels are organized on the store shelves. We explore how a retailer selling a perishable product with deteriorating quality over time can leverage product display to maximize profit and reduce waste. We use an infinite-horizon periodic-review stylized model to optimize product display, discount rate and order quantity for a product with a two-period shelf life, which is fresh in the first period and old in the second period. We find that going from selling only fresh products to selling them alongside old products at an optimized discount using an optimized display setting increases profit by 5.13% and decreases waste by 78.93% on average. Moreover, our results reveal that selling discounted old products via the right display setting can be a win-win proposition for the retailer who can simultaneously increase profits and reduce waste.
