• Selection of Small and Diverse Suppliers and Contractual Performance: Do Set-Asides Pay Off? AI翻译

  摘要：Despite formal supplier diversity initiatives and lofty goals, corporate spending with diverse suppliers is about 7%. Conversely, the U.S. federal government's spending with these suppliers exceeds 25%. The government's use of set-asides, which limit the bidding on certain contracts to small or small and diverse suppliers, is one reason that might explain this difference. Although set-asides entail socioeconomic benefits for these suppliers, they are controversial. Our study contributes to thi...
• Fairness as a Robust Utilitarianism AI翻译

  摘要：This article focuses on the social choice problem in which decisions are based on the utility of multiple stakeholder types. The sum of these utilities-Utilitarian welfare-is one of the most important objectives in solving the social choice problem. While it is the most efficient solution, maximizing Utilitarian welfare may lead to unfair outcomes. However, Encouraging a Utilitarian decision-maker to adopt a fair decision is challenging due to the associated efficiency loss. This article takes...
• Does Greater Visibility Benefit Minority Businesses? Evidence from an Online Review Platform AI翻译

  摘要：In the wake of the Black Lives Matter protests, numerous companies took action to advance racial equality. Several online platforms added a feature that identified minority-owned businesses to help users locate and, thus, support them. In this study, we investigate how reviews and ratings of restaurants in New York City change after being identified as Black-owned on an online platform. We find that the number of reviews increases, but the average rating decreases after restaurants are identif...
• Building Diverse, Equitable, and Inclusive Operations and Supply Chains: Bringing Public Policy Back In AI翻译

  摘要：While we have seen some encouraging examples of firms that try to drive diversity, equity, and inclusion (DEI) practices into their supply chains, progress has been frustratingly slow. We argue that a key impediment today and a potential enabler tomorrow-and thus an important subject of operations and supply chain management (OSCM) research-is the array of public policies that sets the rules of the game in OCSM. We differentiate three types of public policy regimes-laissez-faire, regulatory, a...
• Robust Data-Driven Design of a Smart Cardiac Arrest Response System AI翻译

  摘要：This paper studies the data-driven design of a smart emergency response system for out-of-hospital cardiac arrest (OHCA) that involves drones for automatic external defibrillator delivery and community responders alerted via a mobile application, in addition to ambulances. Our study is motivated by the widespread exploration of drones for delivery service, and the emergence of mobile applications that crowdsource community for emergency response. Based on a historical OHCA dataset with communi...
• Algorithmic Supervisor and Employee Performance AI翻译

  摘要：In this article, we explore the impact of implementing an algorithmic supervisor, a data analytics tool that offers real-time feedback to employees, on their overall performance. We collaborate with a leading service company that initiated the transition from human supervisors to an algorithmic supervisor for managing call agents in their outbound call center on September 18, 2019. We collect data for 220,085 calls over a span of 6 months-that is, 3 months before and 3 months after the introdu...
• Probabilistic Selling with Customization? A Theoretical Analysis AI翻译

  摘要：Customized mystery bag/box products are examples of a new business model of combining probabilistic selling and customization in practice. We develop an analytical framework to study the economic value of customized mystery bag/box products and explore the interrelationship between probabilistic selling and customization. We define probabilistic selling and customization to be complements (substitutes) as that customization increases (decreases) the value of probabilistic selling. We find that...
• 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 ...
• Digital Goods Reselling: Implications on Cannibalization and Price Discrimination AI翻译

  摘要：The resale of used products presents the challenge of cannibalization, particularly pronounced in digital goods markets where perfect substitutes are easily replicable. In this article, we assert that, rather than a threat, resale can serve as an effective pricing tool for managing heterogeneous demand. We consider a seller of digital goods/services who offers a contract to a heterogeneous group of customers at a fixed price for a specified amount of usage allowance. Rather than imposing restr...
• Managing Product-Reusability Under Supply Disruptions AI翻译

  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...
