摘要：This paper proposes a framework for learning customer preferences and optimizing e-commerce assortments, focusing on intra-category multi-choice behavior, where customers buy multiple items within the same category. Unlike traditional discrete choice models (DCMs) that assume single-product purchases, e-commerce data show frequent intra-category multiproduct purchases, especially during promotions. To capture this, we introduce the multi-choice rank list model (MC-RLM), which accounts for both...

摘要：We investigate the fleet repositioning problem aimed at dynamically optimizing vehicle distributions to maximize long-run average social welfare in a vehicle-sharing system. We model the problem as a Markov decision process under the ex ante committed decision scheme, characterizing the balanced myopic policy as optimal for the average reward setting. This policy efficiently aligns vehicle supply with trip demand and mitigates the curse of dimensionality, enhancing computational efficiency sig...

摘要：The long drug approval process in the United States imposes significant development costs on firms and delays access for patients, especially when a therapy that addresses a condition with no existing treatments shows early promise. To shorten approval timelines, the Food and Drug Administration (FDA) has instituted expedited pathways that are designed to bring the most promising therapies to patients more quickly. In this paper, we study the safety implications of the newest of the four exped...

摘要：We evaluate economic immunity to the COVID-19 pandemic accorded by a sector's exposure to artificial intelligence (AI). Using an event study design, we causally estimate the impact of AI industry exposure (AIIE) on shifts in economic activity following the first pandemic-induced lockdown in India. We use payments data from one of India's largest payment gateways and find that a one-standard-deviation increase in AIIE arrests the post-pandemic decline in industry payments by a third. High AIIE ...

摘要：The impact of doctor-patient interactions on patients' service evaluations in online medical consultations (OMCs) has received considerable attention. However, prior research has mainly focused on the individual-level and statistical features of these interactions, with limited exploration of dyad-level dynamics in doctor-patient bidirectional communication. To address this gap, this study examines both individual-level and dyad-level features of online doctor-patient interactions to understan...

摘要：How should retailers and sellers distribute inventory across a large network of (potentially hundreds of) distribution centers? Motivated by the emerging challenges of inventory allocation facing volatile demand, we develop distributionally robust network inventory management policies with cross-fulfillment using a scenario-based approach that is adaptable to feature information and demand correlation. We analytically demonstrate the value of scenario modeling for a two-location newsvendor pro...

摘要：Energy access remains a critical challenge in developing countries due to the unreliability of the power grid. This article studies a servicizing framework in which a third-party firm, distinct from the grid provider, installs and operates a solar-battery system for grid-connected households and charges usage-based fees for energy consumption. The participation service fee is set based on current average household electricity costs, which include the use of gasoline generators during outages. ...

摘要：Recent press coverage of piracy and digital goods touts the practice of subscription (as opposed to selling) as a piracy killer. However, the effectiveness of digital goods subscriptions remains controversial in terms of the profitability for different supply chain members, including content providers and retailers. Specifically, the dearth of existing studies concerning business model choices in distribution channel structures indicates that the literature has yet to provide a comprehensive a...

摘要：This paper investigates how dual-purpose firms-organizations that pursue both profit and social objectives-strategically design their product lines in markets where traditional profit-maximizing firms may imitate their behavior. We find that consumer heterogeneity plays a nonmonotonic effect on the ability of dual-purpose firms to differentiate themselves from profit maximizers, which, in turn, influences firms' product offering strategies and consumer welfare. When consumer heterogeneity is m...

摘要：We examine a firm's personalized pricing (PP) strategies in markets where consumers are uncertain about product quality. In such markets, prices serve not only as a tool for price discrimination but also as a means of conveying quality information to consumers. We reveal that a firm faces a tradeoff between adopting PP to better price discriminate among consumers and not adopting it to signal its high quality. We find that a high-quality firm should adopt PP only when its product quality is kn...
