摘要：We study an agricultural supply chain in an emerging economy, where farmers make land allocation decisions among alternative crops and have the option to sell their harvest either in a side market or directly to a processing plant, and where a government-mandated minimum price guarantee (MPG) is in place. Our study examines a range of pricing strategies that the processing plant can employ to favor a protected crop and the utilization of the processing plant. We begin by considering the Benchm...

摘要：This paper studies the impact of product sharing on competing manufacturers under a platform's different quality entry barrier strategies. We build a game-theoretic analytical model to examine the strategies of two manufacturers: A high-quality manufacturer producing a high-quality product and a low-quality manufacturer producing a low-quality product. We explore three markets: The N-S market where the sharing market does not exist, the L-S market, and the H-S market, where the platform sets l...

摘要：We study the sample complexity of offline learning for a class of structured Markov decision processes (MDPs) describing the inventory control system with fixed ordering cost/setup cost, a fundamental problem in supply chains. We find that a naive plug-in sampling-based approach applied to the inventory MDPs leads to strictly lower sample complexity bounds compared to the optimal bounds recently obtained for the general MDPs. More specifically, in the infinite-horizon discounted cost setting, ...

摘要：In light of the recent frequency of global emergencies that result in overseas delivery delays and cost surges, many multinational brands consider reshaping their sourcing configurations by incorporating local suppliers that may be of lower quality than globally selected counterparts. In this global context, pre-committed emergency renegotiation clauses have gained recognition as a common practice in international commercial contracts, which enable contractual parties to adjust key terms, such...

摘要：An important global trend today is the rise of the secondhand market powered by consumers' desire for sustainability and affordability, as well as a surge in the use of digital resale platforms. While marketing research has primarily focused on the success of new product markets, scant research has tried to understand secondhand markets. To advance knowledge in this area, we investigate how product design innovation affects the value of used products in secondhand markets. Specifically, we dev...

摘要：Patient navigation (PN) programs have been widely implemented to improve healthcare access and reduce avoidable healthcare utilization through care coordination and preventive care management. However, evidence regarding their effectiveness and economic impact remains limited. In this study, we examine the impact of patient enrollment in a PN program in a large accountable care organization (ACO), on emergency department (ED) utilization. Using longitudinal, patient-level data and a staggered ...

摘要：Racial bias in pulse oximetry-a critical noninvasive diagnostic tool that estimates blood oxygen levels using light absorption-has been shown to systematically overestimate oxygen saturation in Black patients, potentially delaying the detection and treatment of hypoxemia. While prior work has focused narrowly on mortality within selected clinical populations or on immediate testing and treatment disparities in emergency department settings, this study investigates how pulse oximetry bias affec...

摘要：Platform owners employ strategic promotions (e.g., platform-initiated penetration pricing) to enlarge their customer base. Under the conventional price-driven economic logic, such promotions are expected to divert demand for the identical goods away from competing platforms, as extensively documented in the conventional brick-and-mortar store context. However, they can also boost the demand. In environments where customers can easily access the identical goods on competing platforms, the incre...

摘要：Product returns are prevalent in practice. Many retailers provide lenient free return policies but with specific return window within which customers are allowed to return products. Motivated by this phenomenon, we consider a single-product online learning and pricing problem with stochastic product returns. A salient feature is that the demand function, depending on price and return window decisions, is initially unknown and must be learned on the fly. The retailer thus faces the classic expl...

摘要：In the classic secretary problem, the decision-maker is faced with an online sequence of candidates with values. Upon seeing a candidate, they have to make an irrevocable take-it-or-leave-it decision. We generalize this framework to the secretary problem with two-tier decision-making (), modeling online selection with hierarchical screening. The problem becomes even more complicated under two-tier decision-making, which captures pervasive real-world scenarios. The first-tier decision-maker (DM...
