Cherry-Picking
分析了8%的消费者在同一天光顾两家超市的挑拣购买行为，发现他们比单店购物者每件商品节省5%，且购物篮规模大67%，符合理性经济行为。
The authors analyze cherry-picking in the context of grocery shopping, comparing the behavior of consumers who visit two grocery stores on the same day (8% of shopping trips) with single-store shoppers. The authors find cherry-picking to be consistent with rational economic behavior. Cherry pickers benefit by saving 5% more per item while buying systematically (67%) larger market baskets.
