  摘要：We study return shipping insurance (RSI) policies prevalent on platforms such as JD.com and Taobao.com. Retailers on those platforms can purchase and provide RSI for consumers (RRSI) or offer an option for consumers to buy RSI themselves (CRSI). With either RSI, consumers will be partially compensated by an insurer for their shipping fees associated with product returns. As the consumers' uncertainty about product fit is realized only after purchase, their decisions whether to purchase CRSI ma...

  摘要：Ensuring continuity of care for patients after an intensive hospitalization episode is a complex dilemma that plagues the US health-care system. Despite its influence on health outcomes such as mortality and readmissions, it is difficult to construct policy instruments such as report cards or penalties for improving continuity of care due to the fragmented nature of post-intensive hospitalization care. However, policy instruments that target other related health outcomes can also benefit conti...

  摘要：Humanitarian workers often operate under highly stressful conditions, view emotional scenes, and face high time pressures. This may bias managerial decision-making in humanitarian logistics, but evidence is lacking. We model humanitarian logistics decisions in an adapted newsvendor setting. We experimentally expose participants to time pressure, noise, and emotional pictures. Using physiological and self-reported data, we confirm that these manipulations have different effects on two component...

  摘要：Ride-hailing platforms such as Uber and Lyft promise to reduce the negative externalities of driving and improve access to transportation. However, recent empirical evidence has been mixed about the impact of ride-hailing on US cities, often resulting in a net increase in traffic congestion and greenhouse gas (GHG) emissions, largely due to increased travel demand and competition with public transit. Pooled rides, in which multiple passengers share a single vehicle, are an effective solution t...
• Hospital admission, facility-based isolation, and social distancing: An SEIR model with constrained medical resources AI翻译

  摘要：COVID-19 is a highly contagious disease that has spread to most countries at unprecedented transmission speed. Medical resources and treatments provided by the healthcare system help reduce the mortality rate and spread of COVID-19 by isolating infectious individuals. We introduce a modified SEIR model that considers individuals access to limited medical resources to characterize the central role of medical resources during the pandemic. We discuss how the three hospital admission policies (hi...
• Managerial flexibility, capacity investment, and inventory levels AI翻译

  摘要：We study the effect of managerial time horizon on two key operations decisions: inventory levels and capacity investment. For identification, we exploit a quasi-natural experiment provided by the staggered adoption of constituency statutes, which alleviate managerial short-termism by providing legal protection to executives adopting a long-term approach in their corporate decisions. Using a staggered difference-in-differences design, we find that, after the reforms, firms incorporated in const...
• Contract selection and piracy surveillance for video platforms in the age of social media AI翻译

  摘要：Pirated video clips, a new form of piracy, have spread rapidly in recent years with the vigorous development of short-video social media platforms such as TikTok and Douyin. This has led to a huge loss of revenue for the film and TV drama industry where the negative economic impact trickles down from legitimate video platforms to content creators. As video platforms fight back against copyright infringement, they need to decide how much effort to invest in detecting and taking down pirated vid...

  摘要：Patient features such as gender, age, and underlying disease are crucial to improving the model fidelity of surgery duration. In this paper, we study a robust surgery scheduling problem augmented by patient feature segmentation. We focus on the surgery-to-operating room allocations for elective patients and future emergencies. Using feature data, we classify patients into different types using machine learning methods and characterize the uncertain surgery duration via a feature-based cluster-...
• Long-term service agreement in electricity supply chain with renewable energy penetration AI翻译

  摘要：We study a long-term service agreement (LTSA) between an original equipment manufacturer (OEM) of a conventional power generator and a utility firm in the electricity supply chain. The OEM offers the LTSA to the utility firm, which specifies the service fee and the maintenance interval. The utility firm dynamically chooses among different resources (conventional, renewable, or emergency) to meet energy demand. An LTSA contracts on a generator's long-term production schedule (i.e., the usage ti...
• From prediction to decision: Optimizing long-term care placements among older delayed discharge patients AI翻译

  摘要：This study examines long-term care (LTC) discharge planning among older delayed discharge patients. While awaiting placements in alternate care such as LTC, these patients occupy hospital beds despite not requiring an intensive level of care. This study proposes a novel discharge decision model based on the Markov decision process (MDP) framework, which incorporates predictions regarding the patients' health trajectory and the associated hospital costs. Our machine learning (ML)-based predicti...
