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...

摘要：As malpractice liability increases, physicians order more and more diagnostic tests/procedures to avoid potential lawsuits. Given the waste/costs of defensive medical practices, some U.S. states enacted tort reform to reduce malpractice liability. As key healthcare providers, hospitals face significant malpractice liability. Despite the fact that a vast amount of medical malpractice occurs in hospitals, the effects of tort reform on hospital performance have not been studied. This study examin...

摘要：On-demand platforms such as ride-sharing services rely heavily on economic incentives to attract, retain, and manage independent workers who have significant discretion over whether and where to work. Using an analytically tractable spatial model, we explore the impact of different pricing and commission strategies on customer demand, driver entry and retention, and their location choices. Our model yields several unique results and actionable insights. We find that flexible commission policie...

摘要：Online healthcare consultation services (OHCS) hold immense potential to transform the healthcare industry. This study seeks to investigate the impact of doctors' participation in OHCS on offline outpatient and inpatient costs, addressing a critical yet underexplored area in the healthcare IT literature. Utilizing an exhaustive dataset from a high-level comprehensive hospital in China over a period of 42 months, we find that doctors' OHCS participation increases outpatient costs by 63.2% (& YE...

摘要：A fundamental principle in operations management holds that increasing the number of servers reduces delays in service systems. To date, no mechanism has been identified that could reverse this effect. We propose, however, that risk aversion can cause increased service capacity to intensify congestion. We study an unobservable M/M/s queue where risk-averse customers choose whether to join based on their anticipated waiting time. We show that, in equilibrium, demand, expected waiting time, expe...

摘要：Retention is a critical challenge for organizations, especially nonprofits, which often face higher turnover than for-profit firms. Unlike many for-profits, nonprofits have fewer financial resources to retain participants, so continued participation depends more on team climate and opportunities to learn by working together. We study these dynamics in the Girl Scouts Cookie Program. We collect sales and troop membership information between 2016 and 2018 from a local Girl Scout council consisti...
