摘要：Problem definition: This paper analyzes a market design problem in Medicare Advantage (MA), the largest risk-adjusted capitation payment program in the U.S. health-care market. Evidence exists that the current MA capitation payment program unintentionally incentivizes health plans to cherry pick profitable patient types, which is referred to as risk selection. However, the root causes of the risk selection are not comprehensively understood, which we study in this paper. Academic / Practical R...

摘要：Problem definition: We use a realistically large, publicly available data set from a global fintech lender to simulate the impact of different antidiscrimination laws and their corresponding data management and model-building regimes on gender-based discrimination in the nonmortgage fintech lending setting. Academic/practical relevance: Our paper extends the conceptual understanding of model-based discrimination from computer science to a realistic context that simulates the situations faced b...

摘要：Problem definition: We develop a framework to plan capacity in each of three sequential stages for ambulatory surgery centers (ASCs). The interdependence of activities, their stochastic durations, and the uncertainties in patient-mix pose significant challenges to managing the capacity of each activity and to achieving a smooth patient ow by coordinating the stages for each patient's visit. These strategic and operational decisionsmust efficiently cover all variations of daily patient demand. ...

摘要：Problem definition: We study the effects of emergency department (ED) physician workload on healthcare system utilization after the patient leaves the ED. Further, we explore the mediating effects of care intensity in the ED on post-ED care use. Academic/practical relevance: ED crowding has been a pressing concern in healthcare systems in the United States and other developed countries. As such, many researchers have studied its effects on outcomes within the ED. In contrast, we present novel ...

摘要：Problem definition: We investigate how the degree of standardization (DoS) across service chain-belonging units impacts units' performance outcomes. We study this question in the nursing home industry, focusing on the DoS in three operational dimensions-customermix, service offering, and service delivery-and its impact on three nursing home outcomes: financial performance, clinical outcome, and resident welfare. Academic/practical relevance: All service chains must decide how unique or standar...

摘要：Problem definition: Cash transfer programs (CTPs) have spread in the last decade to help fight extreme poverty in different parts of the world. A key issue here is to ensure that the cash is distributed to the targeted beneficiaries in an appropriate manner to meet the goals of the programs. How do we design efficient and egalitarian allocation rules for these programs? Academic/practical relevance: Big data and machine learning have been used recently by several CTPs to target the right benef...

摘要：Problem definition: In high-product-variety businesses like fashion, mass production (MP) systems create environmental waste in the form of overproduction on a colossal scale. Mass customization (MC) has been proposed-without solid evidence-as a solution. In this paper, we analyze whether MC can indeed offer a win-win solution that helps both the bottom line and the environment. We also study the impact of three real policy options: promoting MC, charging a disposal fee for overproduction, and...

摘要：Problem definition: This paper investigates and compares two types of food safety auditing structures: decentralized and centralized audits. Academic/practical relevance: Decentralized food safety auditing systems are common among developing economies, that is, different tiers of a food supply chain are audited by separate government agencies. Such an auditing structure has been widely criticized as ineffective at mitigating food safety risks. Some developing countries began implementing centr...

摘要：Problem definition: Treating many blood-related diseases requires transplantation of genetically compatible hematopoietic stem cells (HSCs) extracted from the bone marrow (BM) of live donors or the umbilical cord blood (CB) of babies. To facilitate the search for HSCs, institutions known as BM registries collect the details of potential donors and CB banks store units of CB. This paper focuses on the problem of joint optimization of the capacity of these two institutions. Academic/practical re...

摘要：Problem definition: Six million refugees have been living in camps in 2021 due to multiple armed conflicts worldwide. Regulations often impede refugees' integration into host countries; thus, refugees have to seek help from humanitarian organizations (HOs). HOs traditionally provide in-kind (e.g., food) assistance and now offer cash (monetary assistance) that refugees can spend at local retail stores. However, cash assistance can be exploited by local retailers' market power, which challenges ...
