  摘要：This study is based on the analysis of field data on the revenues and patient flows that we collected on all adult emergency department (ED) visits to a level-1 trauma, tertiary referral center. Our objective was to provide researchers in operations a rich overview of the processes, resources, and metrics of financial and operations performance in the ED. We analyze how patients, physicians, hospitals/physician employer groups, and payers are party to the value created and financial workflow o...

  摘要：Prior research documents the value of network relationships to firm behavior but is relatively silent on how networks influence opportunism in distribution channels. Focusing on a common type of distribution networks in which multiple distributors serve a single, dominant supplier, this study moves beyond a dyadic view to examine how a focal distributor's relational and structural embeddedness in such a distribution network influences its opportunism toward the dominant supplier. In particular...
• Conceptualizing Social Responsibility in Operations Via Stakeholder Resource-Based View AI翻译

  摘要：We seek to conceptualize social responsibility for operations management (OM) research to develop a social responsibility lens through which to view operations. To do so, we first consider the corporate social responsibility, sustainability, as well as the bottom-of-the-pyramid and shared value approaches and identify three challenges to developing such a lens: selecting the level of analysis, tackling the huge multitude of objectives, and developing theoretical underpinnings. We then propose ...
• Implications of Channel Structure and Operational Mode Upon a Manufacturer's Durability Choice AI翻译

  摘要：Motivated by the observation that durability ratings of automobile manufacturers are not necessarily linked to the proportion of leasing but tend to decrease with the density of their dealer networks, we explore the interactions between channel structure (direct interaction with consumers vs. through an intermediary(ies)) and mode of operations (leasing vs. selling) and their implications for a manufacturer's willingness to invest in making her product more durable. Using a manufacturer who le...

• An Analysis of Scoring and Buyer-Determined Procurement Auctions AI翻译
  作者：Santamaria, Natalia
  作者单位：Cornell University
  摘要：In procurement auctions, the object for sale is a contract, bidders are suppliers, and the bid taker is a buyer. The suppliers bidding for the contract are usually the current supplier (the incumbent) and a group of potential new suppliers (the entrants). As the buyer has an ongoing relationship with the incumbent, he needs to adjust the bids of the entrants to include non-price attributes, such as the switching costs. The buyer can run a scoring auction, in which suppliers compete on the adju...
• The Failure of Practical Intuition: How Forward-Coverage Inventory Targets Cause the Landslide Effect AI翻译

  摘要：Seasonal demand for products is common at many companies including Kraft Foods, Case New Holland, and Elmer's Products. This study documents how these, and many other companies, experience bloated inventories as they transition from a low season to a high season and a severe drop in service levels as they transition from a high season to a low season. Kraft has termed this latter phenomenon the landslide effect. In this study, we present real examples of the landslide effect and attribute its ...

• Elective Patient Admission and Scheduling under Multiple Resource Constraints AI翻译

  摘要：We consider a patient admission problem to a hospital with multiple resource constraints (e. g., OR and beds) and a stochastic evolution of patient care requirements across multiple resources. There is a small but significant proportion of emergency patients who arrive randomly and have to be accepted at the hospital. However, the hospital needs to decide whether to accept, postpone, or even reject the admission from a random stream of non-emergency elective patients. We formulate the control ...
