具有风险偏好信息的供应链协调:风险识别与协调契约

Supply Chain Contract with Asymmetric Risk Preference Information

考虑由单一供应商和零售商构成的分布式供应链结构,供应商销售单一产品给零售商,市场需求具有不确定性。其中供应商风险中性,零售商有风险偏好,且其风险偏好信息是私有信息。首先利用期望效用函数将零售商的收益函数进行转化,然后研究了供应商根据对零售商风险偏好程度的估计,设计一个菜单式契约揭示了零售商的真实风险信息。最后对契约进行研究发现,供应商的收益与零售商风险程度的高低,市场需求的不确定性等因素有关。结论表明零售商的风险偏好度较低的时候,供应商的期望收益较大,信息的价值也越高。

A decentralized supply chain in which a single supplier sell a product to a single retailer facing uncertain demand is considered.The supplier is risk neutral and the retailer is risk preference which is private.First,the retailer's profit is expressed by the expected utility function.Second,a contract menu is designed to elicit the retailer's information based on the supplier's estimate of retailer's risk preference information.Finally the contract menu is investigated to show that supplier's profit is affected by the retailer's risk,uncertain demand and so on.The lower the retailer's risk preference is,the more the supplier can gain,and more valuable the information is as well.
