• On the Design of a Shared Waiting Room AI翻译
  作者：Li, Yanting; Roet-Green, Ricky

  摘要：We investigate the design of a waiting area of a service system where different types of customers seek different services, provided by designated servers. We examine two waiting room designs: The designated waiting room, where each server has its own designated waiting area, and the shared waiting room, where all customers are waiting together. In the designated waiting room design, customers observe the number of customers waiting for each service, whereas in the shared waiting room, custome...

  摘要：Do firms voluntarily disclosing emissions have lower levels of greenhouse gases in their in-house and outsourced operations? We examine this question using Scope 1 and upstream Scope 3 emission data reported by firms or estimated by S&P Trucost from 2002 to 2020. Our empirical results reveal that voluntary disclosing firms tend to have lower levels of internal emissions (i.e., Scope 1 emissions) and yet higher levels of external emissions from upstream suppliers (i.e., estimated upstream Scope...
• When Platforms Go Public, Standards Drop AI翻译

  摘要：Peer-to-peer (P2P) platforms facilitate the direct exchange of goods, services, or financial transactions between individuals without the involvement of intermediaries. To maintain trust among their user bases, these platforms must implement stringent access controls to determine which users are eligible to participate in their digital marketplace. We argue that when a platform transitions from private to public ownership, it may be incentivized to strategically lower its access standards and ...

  摘要：Utilizing the introduction of the Trade Reporting and Compliance Engine (TRACE) as an exogenous shock to enhance secondary bond market transparency, we investigate the informational feedback effect of the bond market on supplier innovation in vertical relationships. We find that the increased availability of trading details regarding major customers' outstanding bonds significantly fosters their supplier firms' innovative investment. This positive effect of bond market transparency enhancement...
• Bridging Adversarial and Nonstationary Multi-Armed Bandit AI翻译

  摘要：In the multi-armed bandit framework, there are two formulations that are commonly employed to handle time-varying reward distributions: adversarial bandit and nonstationary bandit. Although their oracles, algorithms, and regret analysis differ significantly, we provide a unified formulation in this article that smoothly bridges the two as special cases. The formulation uses an oracle that takes the best action sequences within a switch budget. Depending on the switch budget, it turns into the ...

  摘要：We analyze product reusability, executed through refurbishment, amid supply disruptions. Consumers trade in used units, which can later be refurbished and sold. Using a three-period model, we determine the optimal reusability level, trade-in and refurbishment policies, trade-in fee, and the prices of new and refurbished units. Our analysis provides a useful framework to understand the interaction between a firm's choice of product reusability and the possibility of supply disruptions. First, w...
• Inventory and Supply Chain Planning Systems as Drivers of Supply Chain Resilience: Analyses of Firm Performance Through the COVID-19 Pandemic AI翻译
  作者：Swink, Morgan; Kovach, Jeremy J.; Roh, Joseph
  作者单位：Texas Christian University; University of North Texas System; University of North Texas Denton
  摘要：We combine insights from information processing theory (IPT), supply chain resilience literature, and collaboration with a leading supply chain planning technology provider to study the effects of excess inventory (a buffering tactic) and usage of supply chain planning systems (SCPSs) (a bridging technology) on supply chain resilience. Utilizing the exogenous disruptions caused by the COVID-19 pandemic as the setting for quasi-natural experiments, we compare profit impact and time-to-recover a...
• Making Delivery Platform Drivers Safer: Platform Responsibility Versus Consumer Empowerment AI翻译

  摘要：The increasing frequency of traffic accidents involving food delivery drivers has raised public concern about the safety of fast delivery services. In response, food delivery platforms have introduced two corporate social responsibility (CSR) strategies to enhance drivers' road safety: One in which the platform assumes full responsibility for extending delivery times and another that empowers consumers to decide on extended delivery times. Additionally, policymakers are mandating that platform...

  作者单位：Tsinghua University; Durham University
  摘要：The attended home healthcare (AHH) industry is experiencing rapid growth due to the rising demand from an aging population and the potential benefits of alleviating pressures on traditional healthcare resources. However, ensuring timely one-on-one AHH services for homebound patients remains a challenge because of cascading delays arising from uncertainties in travel and service times. To address this issue in last-mile homecare delivery, we develop a systematic cascading delay mitigation strat...
