  摘要：Problem definition: We study a nurse staffing problem under random nurse demand and absenteeism. Although the demand uncertainty is exogenous, the absenteeism uncertainty is decision-dependent, that is, the number of nurses who show up for work partially depends on the nurse staffing level. For quality of care, hospitals develop float pools of hospital units and train nurses to be able to work in multiple units (termed cross-training) in response to potential nurse shortages. Methodology/resul...
• Quality Signaling in Rewards-Based Crowdfunding: The Role of Deferred Payments AI翻译

  摘要：Problem definition: The rise of crowdfunding hides a flaw: creators' private information that is unobservable enables them to exploit backers, stalling the sector. To shield backers, platforms now escrow part of raised funds as deferred-payment insurance. We explore whether the implementation of deferred payment (DePay) shapes quality signaling under private information and how to utilize DePay for better campaign outcomes. Methodology/results: We build a stylized signaling game with a represe...
• Selection, Payment, and Information Assessment in Social Audits: A Behavioral Experiment AI翻译

  摘要：Problem definition: Companies often rely on third-party social audits to assess suppliers' social responsibility (SR) practices. Empirical evidence suggests that these audits can often be too lenient and poor practices go unreported, particularly if the auditor feels beholden to the supplier. However, it is unclear how supplier involvement in selecting and paying auditors shapes these outcomes. Methodology/results: We design and conduct a novel incentivized experiment to study how a supplier c...
• A Firm's Operational Risk: Data Set and Empirical Evidence AI翻译

  摘要：Problem definition: A firm's stakeholders would benefit from a quantitative measure of the managerial disclosure of its operational risk and the implications of this disclosure. However, a quantitative and scalable measure of a firm's disclosed operational risk is unavailable. Thus, the firm's stakeholders remain unaware of its disclosed operational risk and the risk's implications. Methodology/results: U.S. law requires a public firm to textually disclose its operational and nonoperational ri...
• Privacy-Preserving Personalized Recommender Systems AI翻译

  摘要：Problem definition: Personalized product recommendations are crucial for online platforms but pose privacy risks. To address these concerns, we propose recommendation policies that adhere to differential privacy constraints. Methodology/results: We develop a theoretical model where the recommendation policy selects products based on consumers' preference rankings, learned from personal data. Unlike conventional recommendation policies that primarily focus on prospering from meeting consumer sa...
• The Economics of Bestsellers: Consumer Search, Sales Ranking, and Social Learning AI翻译
  作者：Lu, Wentao; Yu, Man
  作者单位：Chinese Academy of Sciences; University of Science & Technology of China, CAS; Hong Kong University of Science & Technology
  摘要：Problem definition: Motivated by major e-commerce platforms' diverse practices in bestseller information provision, this paper examines consumers' learning, searching, and purchasing behavior under uncertainty about products' values, whereas a revenue-maximizing platform strategically decides whether and, if so, how to disclose products' past sales information to consumers. Methodology/results: We analyze a two-period Bayesian learning model that embeds consumers' sequential product search in ...
• Self-Control in the Face of Multiple Projects AI翻译
  作者：Li, Qing; Yu, Peiwen
  作者单位：Hong Kong University of Science & Technology; Chongqing University
  摘要：Problem definition: We study how people with present bias make choices when they face multiple projects. Each project consists of a starting and a finishing stage, both requiring costly effort to complete but yield rewards only after project completion. Meth-odology/results: We derive people's perception-perfect strategies for project scheduling. Naifs may start a project, but never finish it. They may multitask; that is, start a new project before finishing an old project. They may not priori...
• On the Equivalence and Performance of Distributionally Robust Optimization and Robust Satisficing Models AI翻译
  作者：Wang, Zhiyuan; Ran, Lun; Zhou, Minglong; He, Long
  作者单位：Beijing Institute of Technology; Fudan University; George Washington University
  摘要：Problem definition: Distributionally robust optimization (DRO) is ubiquitous to address uncertainties inherent in operations management (OM) problems. Recently, an alternative goal-driven framework, robust satisficing (RS), is proposed. RS aims to attain a prescribed target, such as avoiding overshooting the cost budget, as much as possible under uncertainty. The goal-driven modeling philosophy fits many OM problems, yet there is a lack of direct comparisons between DRO and RS. In this paper, ...
• Restructuring Global Supply Chains: Navigating Challenges of the COVID-19 Pandemic and Beyond AI翻译

  摘要：Problem definition: The COVID-19 pandemic imposed unprecedented stresses on global supply chains (GSCs), compelling companies to reassess their supply chain structures and strategies. This crisis has also heightened awareness among businesses, consumers, and policymakers about the critical importance and far-reaching implications of GSC design and management. This unique moment presents a generational opportunity for Operations Management (OM) researchers to document and understand the ongoing...
• OM Forum-Barriers to Implementing Diversity, Equity, and Inclusion (DEI) Programs in Supply Chains: Lessons from Comparing Public and Private Firms AI翻译

  摘要：Problem definition: This OM Forum article explores the barriers hindering the implementation of diversity, equity, and inclusion (DEI) programs in supply chains by analyzing the DEI performance of publicly traded and privately held companies. Whereas the importance of DEI in supply chain management is widely acknowledged, publicly traded and privately held companies exhibit a notable gap in achieving DEI goals. Methodology/results: This article explores the factors that enabled publicly traded...
