This paper analyzes the effect of different salvage value on coordination a supply chain in which risk-neutral manufacture sells single product to retailer. The analyses show that shows that, when retailers surplus products is less than or equal manufacturers, buyback contracts can coordinate chain; When greater only cannot chain, while subsidy realize effectively.

A supply chain model is built in which inventory incentive and promotion co-exist, to maximize the profit. Market demand affected by random factors retailer's promotional effort. The retailer chooses order quantity or purchased options ex ante, determines effort post based on his observation of market demand. asymmetric information will result "double moral hazard", consists hidden action information. In this context, an option contract alone create another "contract-induced" hazard dull...
