Retailer or e-tailer? Strategic pricing and economic-lot-size decisions in a competitive supply chain with drop-shipping

Drop-shipping is an arrangement whereby an e-tailer, who does not hold inventories, processes orders and requests a manufacturer to ship products directly to the end customers. To explore the economic benefits of adopting drop-shipping distribution strategy in a competitive environment, we investigate the profitability and the efficiency of the drop-shipping channel as compared to the traditional channel. Specifically, we develop Economic Order Quantity (EOQ) games with pricing and lot-sizing decisions to examine the strategic interactions between a manufacturer and its retailer/e-tailer in the traditional/drop-shipping distribution channels. We identify conditions under which the drop-shipping channel profitably outperforms the traditional one. It is found that the economic interests of adopting drop-shipping distribution for the channel members may not always be consistent. There are cases where only the manufacture would favour drop-shipping. In this study, we also reveal that the inefficiency caused by lack of coordination in the traditional channel can be alleviated in the drop-shipping channel where the lot-sizing decision is made by the manufacturer. © 2010 Operational Research Society Ltd.
