在零售商具有损失厌恶偏好的假设下,本文研究了由单个供应商和零售商组成的二级供应链中,使用基本合同和期权合同两种情况下零售商的库存决策和供应商质量努力投资决策,并通过对两种合同下均衡结果的比较,分析了期权合同对供应链成员决策的协调作用。研究表明,零售商的损失厌恶偏好越强,其订货量以及供应商的质量努力就越小,这会导致零售商的利润下降,而供应商的利润则会上升。在同时存在基本订货合同和期权购买合同时,零售商存在最优的合同购买组合。
Under the assumption that retailers have loss aversion preference, this paper studies retailer’s inventory decision-making and supplier quality in two-level supply chain composed of single suppliers and retailers under both basic and option contracts Through the comparison of the equilibrium results under the two contracts, this paper analyzes the coordination function of the option contracts on the decision-making of supply chain members. Research shows that the stronger the retailer’s loss aversion preference, the less its order volume and supplier quality efforts, which leads to a decline in retailer profits and a rise in supplier profits. Retailers have the best contractual buying portfolios when there are both basic ordering contracts and options buying contracts.
