Abstract: We consider a retailer that has adopted a last-day-discount strategy for their fresh assortment: all fresh products are put on a uniform 15% discount rate one day before they expire. While this might help the retailer to reduce waste in the short run, it might also harm the retailer in the long run due the long-term negative effects of discounts. To assess this tension, we study the implications of the last-day-discount strategy for the retailer using a difference-in-difference approach on a one-year daily data set of 472 SKU’s across 6 stores. While we find strong short-term effects of last-day-discounts on sales, the long-term effects are small. These short-term effects confirm the notion that last-day-discounting can help reduce waste. The small long-term effects complement the branding literature – which provides strong evidence that frequent discounts deplete brands on the long run – by showing that brands are more resistant to such depletion for last-day-discounting in the fresh product category.
