  摘要：Maintaining a high service level with customers involves a fundamental tradeoff between investing in inventory and investing in expediting the shipping of the additional units needed to achieve that service level. We use a multi-method approach to show how and when ordering decisions are influenced by different levels of expediting costs and target service levels. First, we derive a mathematical model that provides a closed-form solution to this tradeoff. Second, we run a behavioral study to s...
• Tapping into User Effort? Improving Referral Outcomes in Crowdfunding Markets AI翻译

  摘要：Referral programs have received increasing attention as a way to enhance project fundraising in crowdfunding. To improve operational efficiency and performance, many crowdfunding platforms allow users to exert more effort (referral effort) when making referrals. In this paper, we study the impact of users' referral efforts on referral outcomes, using a unique data set from a reward-based crowdfunding platform. We analyze three types of referral effort beyond merely sharing the referral link, n...
• How and Why does a Business-to-Business Firm's Corporate Social Responsibility Disclosure Impact its Dependence on its Major Customers and Major Suppliers? AI翻译

  摘要：Prior research has documented that a firm's disclosure of corporate social responsibility (CSR) makes it a more attractive business partner, boosting its sales. The authors extend this finding to business-to-business (B2B) firms. Using a regulatory change in China as a quasi-natural experiment, they demonstrate that a firm's disclosure of its CSR lowers by 2.1% the firm's dependence (for sales revenue) on its major customers but raises by 3.7% its dependence (for purchases) on its major suppli...

  摘要：We describe the state of supplier diversity efforts by large corporations from an international perspective. We examine data for the companies in the 2020 and 2022 Fortune Global 500 and find that corporate definitions of diversity are dynamic and vary across regions. Furthermore, while supplier diversity efforts are not yet widespread, these initiatives are increasingly common, especially in the form of references to diversity in companies' supplier codes of conduct. Companies in North Americ...
• Dyadic Interactions and Patient Service Evaluation in Online Healthcare Consultations: The Role of Communication Alignment AI翻译

  摘要：The impact of doctor-patient interactions on patients' service evaluations in online medical consultations (OMCs) has received considerable attention. However, prior research has mainly focused on the individual-level and statistical features of these interactions, with limited exploration of dyad-level dynamics in doctor-patient bidirectional communication. To address this gap, this study examines both individual-level and dyad-level features of online doctor-patient interactions to understan...
• Competitive Manufacturers Product-Sharing Strategies: P2P Sharing or B2C Sharing? AI翻译

  摘要：With the rapid development of the sharing economy, many traditional manufacturers gravitate toward the paradigm shift to embrace product/service sharing with B2C (i.e., business-to-consumer) and P2P (i.e., peer-to-peer) sharing models. We develop a duopoly model to investigate the strategic decisions of competing manufacturers regarding three product-sharing strategies: no-sharing (i.e., sales-only), P2P sharing (i.e., sharing products on a P2P platform in addition to sales), and B2C sharing (...
• Response Time Minimization for Cardiac Arrests AI翻译
  作者：Lejeune, Miguel A.; Margot, Francois
  作者单位：George Washington University
  摘要：Cardiac arrests are a significant health concern in the United States, as more than 350,000 occur annually and 90% of them are fatal. Providing quick access to automated external defibrillators is paramount since irreversible damage to vital organs occurs within minutes without cardiopulmonary resuscitation and defibrillation. We propose a novel optimization model to design a network of drones delivering automated external defibrillators in response to out-of-hospital cardiac arrests. The netw...
• Framing Inclusive Practice Options for Financial, Operational, and Community Outcomes AI翻译

  作者单位：Babson College; Babson College
  摘要：While the operations management literature has addressed inclusive business models for large organizations, there has been less focus on how small- and medium-sized enterprises (SMEs) include vulnerable end-users when they are subject to industry constraints and are not able to redesign their business models. In such cases, organizations face variable profits based on the socioeconomic status (SES) of the end-user. We introduce the Inclusive Practice Options (IPO) framework to explain how, wit...
• Impact of Capacity Strain on the Health Status of Patients Discharged From an Intensive Care Unit AI翻译

  摘要：Intensive care units (ICUs) play a vital role in hospitals and often experience capacity strain. Using data from a large teaching hospital, we empirically examine the effect of ICU capacity strain on patient discharge. We find that capacity strain has no effect on the health status of discharged patients and that capacity strain leads to a shorter length-of-stay in the ICU, but the magnitude of the effect is less than half a day in the most extreme scenarios. In post-hoc analyses, we find evid...
• Racial Bias in Pain Measurement Frequency in ICU and its Impact on Early Readmission AI翻译

  摘要：A significant portion of hospitalizations result in readmissions, many of which are preventable. Additionally, over a quarter of admissions necessitate intensive care unit (ICU) stays. These trends impose significant strain on healthcare systems, leading to penalties and reduced reimbursements for healthcare facilities. Consequently, reducing readmissions stands as a critical priority for healthcare institutions, with a specific focus on ICU processes and procedures. While some healthcare proc...
