Dynamic Procurement, Quantity Discounts, and Supply Chain Efficiency
研究单一供应商与单一买家在多次交易中的动态采购，发现使用批发价合同时，多次交易比一次性采购对供应商、买家及终端消费者更有利。
We study a model with a single supplier and a single buyer who interact multiple times before the buyer sells her product in the end‐consumer market. We show that when the supplier uses a wholesale price contract, even under perfect foresight, the supplier, the buyer, and the end consumers benefit from multiple trading opportunities versus a one‐shot procurement agreement.
