  摘要：In this research, we investigate the economics of queueing systems with strategic non-risk-neutral customers, emphasizing the value-at-risk (VaR) framework. It is distinct from the moment-based utility structure of Naor's model by introducing the maximum loss customers can bear with a certain level of confidence. We consider both homogeneous and heterogeneous cases of risk preferences under different information levels. Our findings demonstrate that optimal strategies in observable queueing sy...
• Knowledge Outsourcing From a Consultant: Implications of Absorptive Capacity and Knowledge Reuse AI翻译

  摘要：Consider a client who has a problem she cannot solve by a given due date, and a consultant engaged to help. The consultant sets the price for knowledge outsourcing to maximize his profit. The client sets the quantity of knowledge outsourcing and the portion of the problem she solves in-house to minimize her cost. The client benefits from knowledge outsourcing only to the extent that she has absorptive capacity to understand and utilize that knowledge. In this context, absorptive capacity is dr...
• Don't Follow Reinforcement Learning Blindly: Lower Sample Complexity of Learning Optimal Inventory Control Policies with Fixed Ordering Cost AI翻译

  摘要：We study the sample complexity of offline learning for a class of structured Markov decision processes (MDPs) describing the inventory control system with fixed ordering cost/setup cost, a fundamental problem in supply chains. We find that a naive plug-in sampling-based approach applied to the inventory MDPs leads to strictly lower sample complexity bounds compared to the optimal bounds recently obtained for the general MDPs. More specifically, in the infinite-horizon discounted cost setting, ...
• Efficiency and Interventions of Strategic Driver Relocation for Ride-Hailing Platforms AI翻译

  摘要：Idle drivers' spontaneous relocation, when provided with sufficient information, has the potential to mitigate the supply-demand imbalance in ride-hailing services. As this potential remains ambiguous, this study aims to address two fundamental questions and derive managerial insights: Q1: To what extent can drivers' spontaneous relocation resolve the supply-demand imbalance? Q2: How can subsidies be designed to induce the platform optimum? We propose a leader-follower game-theoretic framework...
• Mixed Appointment Scheduling: Managing Routine and Same-Day Appointments for Outpatient Clinics AI翻译

  摘要：This article introduces a novel scheduling approach for managing a mix of routine and same-day appointments in an outpatient clinic. While the well-known carve-out scheduling (COS) policy reserves the provider capacity for same-day patients, its use of dedicated slots for each patient class may increase the risk of system underutilization or overload and long patient wait times. We propose the mixed appointment scheduling (MAS) policy, which allows routine and same-day patients to share common...
• Targeted Automation and Sustaining Human-AI Learning AI翻译
  作者：Imdahl, Christina; Schmidt, William; Hoberg, Kai

  摘要：In many decision processes, a decision maker or planner must review and optionally adjust the recommendations that are generated by a decision support system (DSS). When the DSS is well-tuned to its task, adjustments by a planner can be rare and may even degrade the DSS's performance. Targeted automation could address these inefficiencies by predicting whether a planner will adjust a recommendation and improve the performance of the system. The remaining recommendations can be automated. Howev...
• Manufacturer Encroachment in the Presence of Production Economies of Scale AI翻译

  摘要：It is well established that a manufacturer generally benefits from encroachment with a profitable direct channel and may also benefit from using encroachment as a threat (i.e., without sales in the direct channel); the retailer may also benefit from both encroachment strategies. Our study provides new insights into the manufacturer encroachment literature by considering the upstream manufacturer's production economies of scale. Contrary to conventional wisdom, we show that an increasing level ...
• Assortment Competition in a Two-Tier Supply Chain Under Cardinality Constraints AI翻译

  摘要：We study a two-tier supply chain in which multiple manufacturers sell their products through a single retailer, and consumer choices follow a Multinomial Logit model. Each manufacturer selects from its portfolio an assortment of products to sell, subject to a cardinality constraint on the size of the assortment. We consider both the case where manufacturers take wholesale prices as given and the case where they set their own wholesale prices. The retailer determines the retail prices of the pr...
• Optimal Growth of a Two-Sided Platform with Heterogeneous Agents AI翻译
  作者：Zhu, Yixin; Chen, Hongfan(Kevin); Zhang, Renyu; Zhou, Sean X.
  作者单位：Shanghai University of Finance & Economics; Chinese University of Hong Kong
  摘要：We consider the dynamics of a two-sided platform, where the agent population on both sides experiences growth over time with heterogeneous growth rates. The compatibility between buyers and sellers is captured by a bipartite network. The platform sets commissions to optimize its total profit over T periods, considering the trade-off between short-term profit and growth as well as the spatial imbalances in supply and demand. We design an asymptotically optimal policy with the profit loss upper-...
• When Are More Information Details Less Useful? A Comparison of Product Contextualization in Customer Images and Review Texts AI翻译

  摘要：Product reviews, a type of user-generated content (UGC), are found to affect sales; however, their impact on product returns has not been fully explored. Research has revealed that inflated ratings and catchy product images may increase returns, which spells trouble for sellers. To address the issue, we examine how product contextualization in customer-posted images and review texts helps online shoppers assess a product's functionality and aesthetics and, in turn, reduce returns. Using the ar...
