摘要：Problem definition: Though the effectiveness and efficiency of education systems depend in part on a committed teacher workforce, high rates of teacher leaving have plagued the U.S. public schools. There are many complex factors at play. A foundational one is that teachers are frustrated by the difficulty and expense of needing to procure many classroom supplies and materials on their own. This has recently become more prominent with the emergence of teacher crowdfunding platforms. With the un...

摘要：Problem definition: Scant empirical research studies the impact of drug shortages on the quality of medical care in hospitals. We study the causal relationship between drug shortages and medication errors using a natural experiment: hurricane damage to factories that produce heparin, an essential medication used frequently in hospitals. Methodology/ results: We collect data on medication errors from the U.S. Food and Drug Administration's Adverse Event Reporting System and drug sales from IQVI...

摘要：Problem definition: We study how to leverage patient-specific information to improve a hospital's operational efficiency. We use abdominal surgery as the clinical setting and study the heterogeneous effects of surgical volume on surgery duration. We develop a framework for using patient-specific information by addressing three important questions: (1) Is the effect of surgical volume heterogeneous across patients with different features? (2) If so, how could patient-specific information that c...

摘要：Problem definition: In this paper, we present a reinforcement learning (RL)based framework for optimizing long-term discounted reward problems with large combinatorial action space and state dependent constraints. These characteristics are common to many operations management problems, for example, network inventory replenishment, where managers have to deal with uncertain demand, lost sales, and capacity constraints that results in more complex feasible action spaces. Our proposed programmabl...

摘要：Problem definition: Digital platforms provide sellers with the opportunity to leverage data analytics products, granting them convenient access to statistical analyses of their business data. To promote the adoption of data analytics products and facilitate the growth of small and medium enterprises (SMEs), a world-leading E-commerce platform initiated a Democratizing Data Analytics (DDA) campaign in May 2021, which gives free data analytics products access to all sellers on the platform. Leve...

摘要：Problem definition: Online marketplaces have revolutionized online sales by creating platforms that connect millions of buyers and sellers. Although the presence of numerous third-party sellers attracts customers, it also results in a proliferation of listings for each product, making it difficult for customers to choose between the available options. To address this issue, online marketplaces employ algorithmic tools to curate and present different product listings to customers. Although tool...

摘要：Problem definition: We study innovative capacity-planning strategies for service systems that encounter significant challenges in maintaining service quality because of worker shortages, a prevalent and growing issue across healthcare, retail, customer service, and other labor-intensive sectors. Methodology/results: Using a stylized queueing model representing a centralized service system, we propose a multistage staffing strategy utilizing capacities of various flexibility. Accounting for dem...

摘要：Problem definition: The rise of digital channels has led to significant media market transformations. This paper studies whether and how digitization, sparked by the launch of Amazon Kindle in late 2007, affected print book sales. Methodology/results: To estimate the impact, we exploit the quasiexperimental variation in the popularity of digital books across different genres or subgenres. We employ difference-in-differences and other identification strategies, and we use print sales data on a ...

摘要：Problem definition: We study the impact of an airline's route-level decisions on the efficiency and resilience of its operations. Methodology/results: Our study uses a proprietary passenger-level data set provided by Southwest Airlines and takes advantage of a regulatory change, the Wright Amendment repeal. The Wright Amendment restricted nonstop service between Dallas Love Field Airport (DAL) and most major destinations. Its repeal led to significant changes in Southwest's service offerings a...

摘要：Problem definition: We study two-sided markets in which competing platforms enforce service standards to control access of providers with heterogeneous service quality and employ pricing strategies to balance supply and demand. We further investigate the effectiveness of launching regulations, aimed to maximize social welfare, in enhancing quality, and we examine multihoming to yield additional insights. Methodology/results: We build a game-theoretic model wherein two platforms enforce service...
