双传染渠道下银行系统性风险的测度研究

运用改进后的双传染渠道模型,依据2014—2022年42家银行的年报数据,从传染损失、倒闭机构数、银行系统损失和溢出至经济系统损失四个维度测度我国银行系统性风险。结果显示,从传染损失或倒闭机构数量单个维度测量系统性风险并分析其生成机制过于片面。综合银行系统损失和溢出至经济系统损失维度能更全面、准确地测度银行系统性风险。降价抛售、债务违约分别是权益损失、银行破产的主要渠道。杠杆高且银行间贷款占比高的银行更脆弱,溢出风险更大。

非对称生产成本变动信息下零售商双渠道的最优契约设计

为研究制造商非对称生产成本变动信息对以大型零售商为主导的零售商双渠道供应链契约设计的影响,分别考虑了无生产成本变动、制造商生产成本变动且信息对称与信息不对称3种情况下的最优渠道策略,以消费者选择理论和委托代理理论为基础,利用KKT条件求解,分析了非对称信息下成本变动对供应链绩效的影响。研究表明,初始的供应链渠道策略在一定条件下仍为最优策略;且制造商生产成本信息的私有性,也并不一定会给供应链系统带来收益损失。

Effect improvement of drug pricing reform based on multi-channel coordination

To improve the effect of the drug pricing reform,a business model of pharmaceutical e-commerce is introduced into the pharmaceutical supply chain.First,based on the measures of the drug pricing reform,a dual-channel model is established,consisting of a drugstore and a hospital.The analysis of the model indicates that the reform leads to higher costs for patients.Then,an e-pharmacy is added to the dual-channel supply chain.Meanwhile,to reduce the home-delivery cost of the e-pharmacy,a multi-channel coordination strategy called“order online,delivery by drugstore”is proposed.By comparing the optimal values under the two models with and without coordination strategy,respectively,the results show that the profits of the e-pharmacy and the drugstore increase while the retail prices of drugs drop,and a large number of patients are diverted from the hospital.Therefore,the business model of pharmaceutical e-commerce with multi-channel coordination can greatly improve the effect of the drug pricing reform.
