  摘要：We propose a general modular approach to support decision-makers' response in the early stages of a pandemic with resource expansion, motivated by the shortage of Covid-19-related intensive care units (ICU) capacity in 2020 in Italy. Our approach uses (1) a stochastic extension of an epidemic model for scenarios of projected infections, (2) a capacity load model to translate infections into scenarios of demand for the resources of interest, and (3) an optimization model to allocate this demand...

  摘要：Firms sometimes acquire partial ownership of their upstream suppliers. Such ownership entails no direct control over the target firm's decision-making; however, both firms might change their pricing strategies after forming a partial ownership relationship. This paper studies the economic impacts of partial vertical ownership (PVO) in a market with downstream competition, where a manufacturer supplies two competing retailers. We find that dividend payments between firms can alter firms' incent...

  摘要：Bundling can change consumers' choice set and affect their purchase decision. It is well documented that consumers' preferences depend on the bundling context. In this paper, we investigate the effects of consumers' context-dependent preferences (CDPs) on the firm's optimal bundling strategy in various competitive situations. We consider a market where a monopolist firm in product category A also sells a product in product category B. We analyze three scenarios in category B: (1) an independen...
• Contracting with multiple suppliers: A multi-item buyer's make versus buy decision AI翻译

  摘要：We consider a multi-item buyer's make versus buy decision. The buyer sells two substitutable products with uncertain demand. Each product requires a different item, which the buyer procures from two separate suppliers (one for each item) who offer quantity-payment contracts under asymmetric information. The buyer can make one of the items but not both. We compare the buyer's expected profit between buying both the items and making one item (and buying the other), when it can make the item at t...
• 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...
• When does it pay to invest in pricing algorithms? AI翻译

  摘要：Nowadays, firms frequently use big data and pricing algorithms to offer consumers personalized prices according to their willingness to pay. Advances in information technologies have further facilitated the use of customized pricing, which we consider an important facet of transformative marketing. At the outset, personalized pricing may appear to reduce the asymmetry of information between the firm and consumers, and benefits the firm but hurts consumers. To investigate this view, we consider...
