"Managing Global Supply Chains: Incentives, Risk, and Information"

市场日益全球化的特性极大地增加了供应链的竞争、风险和动态。利用管理学/运筹学和经济学的工具，本研究的目的是探索全球供应链中在激励和合同、风险和信息管理领域出现的新问题。 第一个研究主题反映了企业的核心竞争优势与与全球分散的供应链成员进行深度合作的需求之间的紧张关系。后者的这些非核心活动越来越多地通过“全球团队”来处理。这个全球团队需要长期合作的支持(例如沃尔玛或百思买及其国际供应商)。我们研究了长期重复的相互作用如何影响运营决策(例如，库存和采购)、垂直合同和供应链的绩效。全球化的供应链还面临更多的供应方风险/中断。研究的第二个目的是探讨供给侧不确定性对协调和运营决策的影响。最后，快速发展的信息技术刺激了B2B在线交流。然而，供应链成员之间的长期合同仍有许多优势。在线现货市场对长期关系有何影响？他们是相互支持还是相互阻碍？与长期合同的信息共享相比，信息不对称与现货市场价格和供应不确定性有何关联？这对业绩有何影响？ 这项研究的结果将提供新的见解，帮助企业建立战略合作伙伴关系，有效管理信息和风险，并将指导政府培育长期关系和信息/风险分担。

The increasingly global nature of markets has greatly increased the competition, risk and dynamics of supply chains. Utilizing the tools from Management Science/Operations Research and Economics, the objective of this research is to explore emerging issues in a global supply chain in the areas of incentives and contracts, risk and information management. The first research topic reflects the tension between the firms' core competitive advantages and the need for deep collaborations with globally dispersed supply chain members. These latter non-core activities are increasingly handled through a "global team." This global team needs the support of long-term collaboration (e.g. Walmart or Best Buy along with their international suppliers). We investigate how long-term repeated interactions affect operations decisions (e.g., inventory and procurement), vertical contracts, and the performance of supply chains. Globalized supply chains also face increased supply-side risk/disruptions. The second purpose of the research is to explore the impact of supply-side uncertainty on coordination and operations decisions. Finally, fast-developing information technology has stimulated B2B online exchange. However, long-term contracts between supply chain members still have many advantages. How does online spot market interfere with the long-term relationships? Do they support or hinder each other? How is the information asymmetry associated with spot market prices and supply uncertainty compared to the information sharing associated with longer term contracts, and how does this affects performances? The result of this research will provide new insights that will help firms to build strategic partnerships and efficiently manage information and risk, and will guide the government in nurturing long-term relationships and information/risk sharing.
