Product Returns and Assortment Decisions: A Strategic Analysis of Online and Offline Competition
研究了线上与线下零售商在退货和品类决策上的竞争，发现线上商店倾向销售易合身产品以减少退货，而实体店可能利用有限空间销售难合身产品以吸引客流，并分析了“线上购买、店内退货”政策的影响。
The authors present a model of product returns and assortment decisions in the context of online–offline retail competition. In equilibrium, the online store optimally offers easy-to-fit products to reduce costly returns. The competing brick-and-mortar retailer (BMR) faces a subtle trade-off between generating higher sales and attracting more foot traffic, and thus it might use its limited store size to stock harder-to-fit products. The authors’ model provides a rationale for the prevalence of relatively lower-quality products sold online and the steady growth of specialty stores within the changing footprint of traditional retailing. The model is extended to include possibilities such as a physical store opening an online channel to compete with the online store. The authors apply this framework to investigate the possibility and consequences of retailers collaborating to handle returns. Specifically, a recent “buy online and return in store” (BORS) return policy allows consumers to return online purchases directly to a competing BMR. In the short run, BORS increases the BMR's foot traffic and the volume of returns. In the long run, BORS expands the online retailer's assortment and increases the BMR's foot traffic. BORS can be sustained in the long run if the BMR is small or if the cost-saving effect is large.
