2024年5月29日上午，现代供应链管理研究院第100期学术论坛在笃行楼712会议室如期举行。主讲人胡震禹，现任新加坡国立大学Department of Analytics & Operations主任讲席副教授，是《M&SOM》的副主编，MS、OR等期刊的审稿人。他于伊利诺伊大学香槟分校获得工业工程博士学位，在中山大学获得数学学士学位。他的研究重点为动态定价和收益管理、供应链管理以及机制和信息设计。他在《Management Science》、《Operations Research》、《Journal of Mathematical Economics》、《Production and Operations Management》、《Manufacturing & Service Operations Management》等期刊上发表和录用多篇论文。本期报告题目为“Information Design of a Delegated Search”。
胡震禹老师就他的研究成果向在场的参会人员进行了细致而又精彩的汇报分享。与会的师生就分享内容展开探讨与交流，现场气氛热烈，发言踊跃，讨论深入。分享结束后，研究院陈文博副院长对胡老师的精彩分享表示感谢，也向到场师生对ISCA明哲学术论坛的长期支持表示感谢。研究院从建院以来坚持每两周举办一次学术论坛，邀请了众多领域内的知名学者来到财园分享交流，如今已举办至100期。研究院希望通过论坛能够为师生真正起到拓宽科研协作渠道，搭建学术交流平台的作用。
久久为功，善作善成。研究院第100期ISCA明哲学术论坛的成功举办既标志着一个阶段性的圆满，也预示着新的起点。未来，研究院会继续加强高质量科研交流平台建设，促进领域内学者间的交流讨论，从而产出更多更优质的科研成果，为学校的双一流建设和新时代东北全面振兴贡献力量。
【摘要】
A principal delegates a sequential search in finite horizon to an agent, who bears the search cost and controls when to terminate the search. Upon termination, the search payoff is split between the principal and agent. However, only the principal can evaluate each search outcome, whose value is thus unobservable to the agent. Leveraging this informational advantage, the principal designs an information policy to strategically provide the agent with some information about the search results over time. We obtain a complete analytical characterization of the principal’s optimal policy, which is fully prescribed by a sequence of deterministic acceptance standards, one for each period. The agent is recommended and voluntarily willing to continue the search if and only if the current termination payoff fails to meet that period’s standard. In particular, the principal gradually lowers the standard over time. When the search results are recallable, the optimal policy provides no information and the agent keeps searching up to a cutoff period, after which the acceptance standard in each subsequent period is determined independently of other periods by equating the agent’s search cost with his marginal return from an additional search in that period. When the search results are not recallable, the acceptance standards are informative and determined recursively across different periods as the optimal stopping thresholds that the principal would employ should she conduct each search by herself at a shadow cost. The shadow cost signifies how difficult it is for the principal to persuade the agent to conduct the search.
