摘要：Problem definition: Online retailing platforms are increasingly relying on personalized recommender systems to help guide consumer choice. An important but understudied question in such settings is how many products to include in a recommendation set. In this work, we study how the number of recommended products influences consumers' search and purchase behavior in an online personalized recommender system within a retargeting setting. Methodology/results: Via a field experiment involving 1.6 ...

摘要：Problem definition: We study the problem of forecasting an entire demand distribution for a new product before and after its launch. Firms need accurate distributional forecasts of demand to make operational decisions about capacity, inventory, and marketing expenditures. We introduce a unified, robust, and interpretable approach to producing these pre- and postlaunch distributional forecasts. Methodology/results: Our approach is inspired by Bayesian model averaging. Each candidate model in ou...

摘要：Problem definition: The paucity of data on governmental regulatory agencies' product safety defect investigations has restricted our knowledge about (1) the determinants of a regulator's decisions to open or close an investigation, (2) the process it follows between opening and closing of an investigation, and (3) the outcomes of the investigation when it is closed. Methodology/results: The authors view a safety regulator's opening and closing of a product defect investigation as a decision of...

摘要：Problem definition: To investigate the interplay between servicizing and remanufacturing, two widely used strategies in the circular economy, and its impact on firms' economic and environmental performance, we consider a profit-maximizing manufacturer who explores the possibility of jointly adopting the two strategies. Methodology and results: We develop optimization models that capture the main attributes for servicizing (pay-per-use, demand pooling) and remanufacturing (lower production cost...

摘要：Problem definition: Coordinated care network (CCN) is a burgeoning paradigm where patients' diagnosis and treatment plans are developed based on collaboration between multiple, colocated medical specialties to holistically address patients' health needs. A primary performance metric for CCNs is how quickly patients can complete their itinerary of appointments at multiple medical services in the network. Rapid completion is critical to care delivery but also presents a major operational challen...

摘要：Problem definition: Vertical integration, a strategic approach where firms control multiple stages of production and distribution, offers potential operational efficiencies and market power. Although the operations management (OM) literature has emphasized its benefits for supply chain coordination and cost savings, antitrust studies raise concerns about how vertical mergers may enable dominant firms to limit competition by creating entry barriers and harming consumer welfare. Despite extensiv...

摘要：Problem definition: Motivated by the behavior of drivers on ride-hailing platforms (individual drivers decide whether to work based on the offered wage and where to locate themselves in anticipation of future fares), we examine how the introduction of autonomous vehicles impacts the strategic behavior of human drivers and driver welfare. Specifically, we consider a setting in which a ride-hailing platform deploys a mixed fleet of conventional vehicles (CVs) and autonomous vehicles (AVs). The C...

摘要：Problem definition: The drug development process has historically lacked transparency, leading to selective reporting of clinical trial results. Although clinical trial transparency aims to address this issue, increased public scrutiny may make managers more risk averse, potentially stifling novel research and development (R&D) initiatives. This raises the following question. Does transparency hinder technologically novel R&D? Methodology/results: Using data from nearly 10,000 clinical trials ...

摘要：Problem definition: The joint assortment and pricing problem is notoriously difficult to solve, especially for large-scale issues subject to various operational constraints arising from business practices. In this paper, we delve into the joint optimization challenge under constrained logit choice models, accounting for product-differentiated price sensitivities across static, randomized, and dynamic contexts. Methodology/results: We develop a unified optimization methodology that applies effi...
