  摘要：We investigate the impact of skewed demand on robust inventory management. Including skewness in calculations leads to cubic constraints that prevent a standard two-stage method from deriving an explicit and tractable objective function. To overcome this roadblock, we propose a joint optimization method to directly derive the robust solution in a closed form. The joint optimization method is widely applicable to various robust inventory models with different ambiguity sets. The notable advanta...

  摘要：In service systems, customers tend to overutilize resources, resulting in high congestion. We study a non-coercive way to alleviate congestion based on customers' awareness of the negative waiting externalities they impose. To this end, we revisit Naor's rational-queue model by adding a term that captures the cost a customer associates with the waiting time generated for other customers encountered during their sojourn. First, we show that this modification preserves the threshold structure of...

  摘要：Effective management of election campaigns involves dynamic decision-making under uncertainty. Traditional approaches rely heavily on pre-planned strategies that often fail to adapt to real-time changes in voter sentiment and external factors. This paper introduces the Online Election Campaign Planning Problem (OECPP) to optimize the scheduling of campaign activities in the context of U.S. presidential elections. OECPP incorporates sequentially updated predictions that represent assessments of...
• Multichannel Experience, Product Attributes, and Consumer Return Behavior: An Empirical Analysis AI翻译

  摘要：Omnichannel retailing has changed the way consumers search for, evaluate, and purchase products. At the same time, product returns remain a costly and persistent operational challenge. Conventional wisdom holds that adding sales channels, particularly combining physical and non-physical touchpoints, should improve information about product fit and reduce return rates. However, it is unclear how the shopping experience across multiple channels influences what consumers buy and whether they retu...
• Unveiling the Human Touch: Enhancing Customer Satisfaction Through Personal Profiles of Social Media Customer Service Agents AI翻译

  摘要：Firms are rapidly adopting social media platforms to optimize their customer service operations. Given the central role of social media as a primary point of contact with customers and the critical importance of maintaining high levels of customer satisfaction, it is imperative to craft positive experiences during service interactions. To enhance customer interaction with a personal touch, U.S. telecom giant T-Mobile replaced standardized profiles with personal profiles for its social media cu...
• Managing Quality Risk in a Decentralized Supply Chain: Contractual Incentives and Product Recall Insurance AI翻译

  摘要：We consider a two-echelon decentralized supply chain where the probability of selling nondefective products depends on the supplier's quality improvement and the buyer's inspection efforts. Products assembled from defective components cause a recall that leads to external failure costs for the buyer. Both players' efforts are not contractible and it is a challenge to align inspection and quality-improvement efforts in a decentralized supply chain. We find that a procurement contract can provid...
• Bond Market Transparency and Innovation Along the Supply Chain AI翻译

  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...
• A practical guide to causal inference in healthcare operations using single-world intervention graphs (SWIGs) AI翻译

  摘要：Observational studies in operations management (OM) increasingly guide managerial, clinical, and policy decisions in healthcare. To strengthen their rigor, empirical OM research has turned toward causal inference. However, reliably attributing specific effects to interventions using observational data remains challenging. This tutorial describes a causal inference approach for healthcare OM, centered on single-world intervention graphs, which unify the potential outcomes and do-calculus framew...
• Collateral damage: Environmental risk shocks and process innovation AI翻译

  摘要：Unforeseen events such as accidents and disasters cause substantial economic losses to firms worldwide each year. It is, therefore, crucial for firms to make targeted adjustments to their processes to effectively manage operational risks from such events. We examine whether and how firms engage in process innovation in response to elevated environmental risk. By exploiting exogenous shifts in environmental risk created by nearby spill and pollution (SP) accidents, we investigate the impact of ...
• Carbon Neutrality and Shareholder Value: Examining the Role of CO Abatement Technologies AI翻译

  摘要：To address climate change, firms that pursue carbon neutrality might adopt various CO2 abatement technologies, including purchasing carbon credits; investing in third-party CO2 capture and storage; or redesigning products, processes, buildings, and energy sources to abate CO2 emissions. Existing research yields mixed evidence of the effects of such actions, especially technological choices, on shareholder value, though. Building on the Natural Resource-Based View, this article seeks to establi...
