摘要：Problem definition: We examine how to manage turnover among drivers delivering parcels for last-mile platforms. Although driver attrition in these platforms is both commonplace and costly, there is little understanding of the processes responsible for this phenomenon. Methodology/results: We collaborate with a platform to build a structural model to estimate the effects of key predictors of drivers' decisions to leave or remain at the platform. For this estimation, we apply a dynamic discrete-...

摘要：Problem definition: Modern assembly projects usually involve many interrelated tasks outsourced to suppliers/contractors, and the project outcome depends on all contractors' minimum effort level. To mitigate risks in such projects, the original equipment manufacturer (OEM) often uses a risk-sharing contract, under which the payment to the contractors depends on the minimum effort level. The question of how to structure supply contracts in such settings is the focus of our study. Methodology/re...

摘要：Problem definition: Inventory management problems with periodic and controllable resets occur in the context of managing water storage in the developing world and dynamically optimizing endcap promotion duration in retail outlets. In this paper, we consider a set of sequential decision problems in which the decision maker must not only balance holding and shortage costs but discard all inventory before a fixed number of decision epochs with the option for an early inventory reset. Methodology/...

摘要：Problem definition: We study a multiperiod, multiproduct, dynamic pricing problem with price adjustment costs known as menu costs. In this setting, decision makers, such as retailers or online platforms, incur a fixed menu cost whenever prices are updated between periods as well as a variable menu cost that linearly scales with the number of between-period price changes. From a demand standpoint, the random number of customers arriving in each period is assumed to be arbitrarily distributed, w...

摘要：Problem definition: Imperfect produce-edible but cosmetically flawed fruits and vegetables-is often excluded from store shelves, contributing significantly to food waste. Commercializing imperfect produce presents a promising opportunity to reduce waste. This study examines how grocery retailers can best choose from three common retailing strategies: discarding imperfect produce, bunching it with cosmetically perfect produce, or differentiating by selling perfect and imperfect produce separate...

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: This study investigates a seller's allocation of a limited resource to sequentially arriving customers when the seller is influenced by two types of mental accounting bias: prospective accounting (overestimating future revenue) and behavioral discounting (underestimating future revenue). Methodology/results: We establish structural properties on how mental accounting affects capacity allocation decisions and performance. Interestingly, whereas additional capacity consistent...

摘要：Problem definition: Collaborations between researchers and practitioners in operations management are becoming more common, and they can bridge the gap between theory and real-world application. This paper explores the process of managing such collaborations, emphasizing the importance of mutual trust, stakeholder management, and the alignment of academic rigor with practical value. Methodology/results: Drawing on experience and previous operations management literature, the study describes th...
