摘要：Problem definition: Integrating contests into established firm-driven User Generated Content (UGC) communities presents a complex interplay between innovation and communal engagement. The impact of such contests on both the creative outcomes and the community's dynamics remains largely unexplored. Methodology/results: We combine two different data sources stemming from the 3D printing platform Thingiverse, allowing us to compare (a) regular content creation activities shared with the existing ...

摘要：Problem definition: Motivated by the widespread adoption of iterative project management techniques, we study the effects of workflow, iterative or sequential, on innovative behavior and performance. Methodology/results: We conduct a series of laboratory experiments. Our first experiment shows that, in an open-ended creative challenge, iterative task completion leads to better outcomes than sequential task completion. In the second experiment, we show that the advantage of iterative workflow f...

摘要：Problem definition: Standardized processes have improved operational performance across various sectors, including healthcare. A persistent gap, however, remains between evidence-based standards and actual clinical practice. Automated alert systems offer a solution by identifying situations where standards apply and prompting workers to act accordingly. In this study, we focus on sepsis, a life-threatening condition, for which timely performance of standard care actions-that is, compliance-is ...

摘要：Problem definition: We empirically study the market for ride-hailing services. In particular, we explore the following questions: (i) How do the two-sided market and prices jointly form in ride-hailing marketplaces? (ii) Does surge pricing create value, and for whom? How can its efficiency be improved? (iii) Can platforms' strategy on revenue sharing with drivers be improved? (iv) What is the value generated by ride-hailing services, including hosting rival taxi services on ride-hailing apps? ...

摘要：Problem definition: In practice, supply chain parties often have limited capital, requiring them to seek financing and bear bankruptcy risk. In this paper, we behaviorally investigate a trade credit contract between a supplier and a capital-constrained retailer, the latter of which may face bankruptcy risk. After the supplier proposes a wholesale price, the retailer purchases a quantity through trade credit if its initial capital is insufficient and repays the supplier after demand is realized...

摘要：Problem definition: We study a dual sourcing problem in an increasingly volatile world. We consider two types of volatilities. External volatilities reflect fluctuating economic conditions via an underlying Markov-modulated state-of-the-world that affects the two suppliers' cost structures, capacity limits, supply mechanisms, and demands. Internal volatilities affect the actual outputs resulting from random supply processes. Demand distributions are impacted by both types of volatilities. Meth...

摘要：Problem definition: We study how clinical teams adaptively respond to realtime deviations from the planned operating room (OR) schedules and the associated consequences of these responses. Specifically, we explore whether clinical personnel adjust their service speed when they are ahead of or behind the original schedule and whether this affects patient reoperation rates. We then analyze the complicated relationships between OR schedules, patient wait times, and reoperations to offer recommend...

摘要：Problem definition: In many matching markets, some agents are fully flexible, whereas others only accept a subset of jobs. For example, ride-sharing drivers can specify on the platform the destinations that they are willing to accept. Conventional wisdom suggests reserving flexible agents, but this can backfire; anticipating higher matching chances, agents may misreport as specialized, reducing overall matches. We ask how platforms can design simple matching policies that remain effective when...

摘要：Problem definition: How should (apparel) retailers manage product sizes? For example, if most customers wearing a given shoe size, such as 9.5, are willing to accept a half-size up or down, is it necessary for a retailer to carry that size at all? Additionally, although identical products in different sizes are treated as distinct stock-keeping units in inventory management, they are often aggregated for assortment and strategic planning. However, there is no theoretical justification for this...

摘要：Problem definition: Concern about product quality due to the inability to experience products physically has been a major factor that hinders consumers from purchasing online. To ease such concerns, online platforms and sellers have been engaged in various activities to reveal product quality information. Platform can provide certification to products sold via its marketplace, and sellers can voluntarily disclose their private quality information. Despite platform certification and seller disc...
