公平偏好和销售努力下供应链期权契约协调

考虑公平中性的供应商将报童类商品售给公平偏好的零售商，商品需求随机且受销售努力影响。刻画了期权契约下零售商关于实物和期权商品采购及销售努力的联合策略，设计了协调供应链的期权契约和促销成本分担机制。研究表明：在确保零售商参与供应链下，无论契约参数如何设计，零售商要么仅采购实物商品，要么同时购买实物商品和期权；且仅当设计的契约能诱导零售商购买期权时，供应链的协调才可能实现。探讨了公平偏好对零售商策略和协调契约的影响，结果表明：零售商越偏好公平，实物商品采购量和努力水平越低，但期权购买量依赖于契约参数之间的关系；协调契约可行域随公平偏好程度递减，但始终存在；在协调契约下，零售商的策略选择与公平偏好程度无关。最后实施了数值分析。

Supply Chain Coordination via Option Contracts with Fairness Preference and Sales Effort

Considering a supply chain system consisting of a fairness-neutral supplier and a fairness-concerned retailer, where the supplier sells newsvendor-like commodities to the retailer, who can exert promotion effort to enhance stochastic market demand of the commodities. An option contract model is constructed based on fairness preference theory, where the retailer can buy physical goods or options goods.
