  摘要：Problem definition: In practice, supply chain parties often have limited capital, requiring them to seek financing and bear bankruptcy risk. In this paper, we behaviorally investigate a trade credit contract between a supplier and a capital-constrained retailer, the latter of which may face bankruptcy risk. After the supplier proposes a wholesale price, the retailer purchases a quantity through trade credit if its initial capital is insufficient and repays the supplier after demand is realized...
• Product Return Policies: The Impacts of Vertical Bargaining and Contracting with Retail Competition AI翻译

  摘要：Problem definition: Although many retailers allow consumer returns via moneyback guarantees (MBGs) to stimulate consumer demand, some may choose not to. Most existing literature emphasizes factors from the marketing side. However, it is not uncommon that the returned products from unsatisfied consumers are further returned to the upstream manufacturer. How the upstream manufacturer-retailer interactions impact the downstream MBG policies is unclear. Methodology/results: We adopt a multiunit bi...
• Linking Medication Errors to Drug Shortages: Evidence from Heparin Supply Chain Disruptions Caused by Hurricane Maria AI翻译
  作者：Park, Minje; Carson, Anita L.; Conti, Rena M.
  作者单位：University of Hong Kong; Boston University; Boston University
  摘要：Problem definition: Scant empirical research studies the impact of drug shortages on the quality of medical care in hospitals. We study the causal relationship between drug shortages and medication errors using a natural experiment: hurricane damage to factories that produce heparin, an essential medication used frequently in hospitals. Methodology/ results: We collect data on medication errors from the U.S. Food and Drug Administration's Adverse Event Reporting System and drug sales from IQVI...
• Hold Me Accountable: Anonymity and Prosocial Behavior in Services AI翻译
  作者：Glew, Rob; Senot, Claire
  作者单位：McGill University; Tulane University
  摘要：Problem definition: Many services rely on the prosocial behavior of consumers that benefits the wider community for effective delivery, such as bike-sharing schemes, self-service checkouts in grocery stores, and pathology screening services, yet there are frequent challenges in motivating honest, cooperative user behavior in these services. We build on existing research to argue that the degree of anonymity of users toward the service provider can be used to facilitate their prosocial behavior...
• Capacity Rationing in Multiserver, Nonpreemptive Priority Queues AI翻译
  作者：Baron, Opher; Lu, Tianshu; Wang, Jianfu
  作者单位：University of Toronto; City University of Hong Kong
  摘要：Problem definition: Many service and manufacturing systems use both capacity rationing (CR) and priority to differentiate among their customers. We model these as a two-class nonpreemptive priority M/M/c queueing model and the practice of CR; an arriving low-priority customer can directly enter service only when the number of idle servers is higher than the CR level, k. For these systems, we separately discuss two important features that are common in practice but ignored in the literature; su...
• Matching Patients with Surgeons: Heterogeneous Effects of Surgical Volume on Surgery Duration AI翻译
  作者：Pourghannad, Behrooz; Wang, Guihua

  摘要：Problem definition: We study how to leverage patient-specific information to improve a hospital's operational efficiency. We use abdominal surgery as the clinical setting and study the heterogeneous effects of surgical volume on surgery duration. We develop a framework for using patient-specific information by addressing three important questions: (1) Is the effect of surgical volume heterogeneous across patients with different features? (2) If so, how could patient-specific information that c...

• The High Impact of Hurricanes on Prices in Low-Income Communities AI翻译
  作者：Barriola, Xabier; Schmidt, William
  作者单位：Tilburg University; Emory University
  摘要：Problem definition: Responding to large hurricanes requires the deployment of food, shelter, and medical assistance to relieve the immediate needs of the victims. These services are supported by, and eventually fully transitioned to, local resources, such as grocery stores. However, disparities in local infrastructure and services may result in lowincome communities bearing a disproportionate burden from these disasters. We investigate this possibility by testing for differences in the percent...
• On the Equivalence and Performance of Distributionally Robust Optimization and Robust Satisficing Models AI翻译
  作者：Wang, Zhiyuan; Ran, Lun; Zhou, Minglong; He, Long
  作者单位：Beijing Institute of Technology; Fudan University; George Washington University
  摘要：Problem definition: Distributionally robust optimization (DRO) is ubiquitous to address uncertainties inherent in operations management (OM) problems. Recently, an alternative goal-driven framework, robust satisficing (RS), is proposed. RS aims to attain a prescribed target, such as avoiding overshooting the cost budget, as much as possible under uncertainty. The goal-driven modeling philosophy fits many OM problems, yet there is a lack of direct comparisons between DRO and RS. In this paper, ...
• Restructuring Global Supply Chains: Navigating Challenges of the COVID-19 Pandemic and Beyond AI翻译

  摘要：Problem definition: The COVID-19 pandemic imposed unprecedented stresses on global supply chains (GSCs), compelling companies to reassess their supply chain structures and strategies. This crisis has also heightened awareness among businesses, consumers, and policymakers about the critical importance and far-reaching implications of GSC design and management. This unique moment presents a generational opportunity for Operations Management (OM) researchers to document and understand the ongoing...
