  摘要：The Nursing Home Compare system administrated by the Centers for Medicare & Medicaid Services (CMS) is widely used by patients, medical providers and payers. We argue that the rating system is prone to inflation in self-reported measures, which leads to biased and misleading ratings. We use the CMS rating data over 2009-2013 and the corresponding financial data reported by Office of Statewide Health Planning and Development and patients' complaints data reported by California Department of Pub...
• Horizontal Subcontracting From Competitors: When and What? AI翻译

  摘要：We investigate horizontal subcontracting between two firms that compete in selling to uncertain markets. Each firm manages resources to make a key component indispensable for final assembly by both firms. A horizontal subcontract stipulates that one of them prepares key component or even produces final product for the other. The subcontract can be signed before or after resource preparation, which we refer to as forward and spot subcontracting, respectively. With the presence of demand uncerta...

  摘要：Breast cancer, the leading cause of cancer death for women, can be detected at earlier stages through mammography screening. Therefore, most developed countries implemented population-based mammography screening programs. However, cost of mammography and limited resources in terms of number of trained personnel and diagnostic machines prevent mammography screening to be adopted by many other countries. In fact, even in resource-rich countries, there is a growing concern about cost of mammograp...

  摘要：Many parts of the healthcare system remain fragmented and outpatient surgical care is no exception. In this study, we develop a coordinated pre-operative scheduling approach between Anesthesiology and Internal Medicine to optimize patients' medical conditions prior to surgery. Coordinating these two services has conceptual appeal because any health issues discovered by the anesthesiologist can often be addressed by a general internist. We design a patient-centered approach that allows the pati...
• Leveraging Big Data to Balance New Key Performance Indicators in Emergency Physician Management Networks AI翻译

  摘要：Managing emergency physicians is a complex task and has increasingly intensified with the recent consolidation of many emergency departments (EDs). Large-scale physician groups are facing challenges in resource deployment and performance evaluation. To objectively evaluate physicians across facilities, we leverage big data from an emergency physician management network and propose data-driven metrics using a large-scale database consisting of 84 hospitals, 1,079 physicians, and 10,615,879 pati...
• Conditional Promotions and Consumer Overspending AI翻译

  摘要：This study investigates the effects of conditional promotions (e.g., buy 2 or more, get 30% off; spend $50 or more, get $15 off) on consumer behavior and the seller's profit. When a deal is presented with a minimum purchase quantity or a minimum spending requirement, experimental studies have shown some consumers are induced to spend more in order to obtain a discount. To study this behavior, we model a market in which consumers can be heterogeneous in two dimensions: willingness to pay for th...
• On the Properties of Yield Distributions in Random Yield Problems: Conditions, Class of Distributions and Relevant Applications AI翻译
  作者：Kouvelis, Panos; Xiao, Guang; Yang, Nan
  作者单位：Washington University (WUSTL); Hong Kong Polytechnic University; University of Miami
  摘要：In this study, we propose two technical assumptions to ensure the unimodality of the objective functions in two classes of price and quantity decision problems with one procurement opportunity under supply random yield and deterministic demand in a price-setting environment. The first class of problems involves a decentralized supply chain/assembly system under different configurations, and the second class focuses on a single firm's price and quantity decisions under different contracts, paym...
• Should You Kill or Embrace Your Competitor: Cloud Service and Competition Strategy AI翻译
  作者：Li, Bo; Kumar, Subodha
  作者单位：Pennsylvania Commonwealth System of Higher Education (PCSHE); Temple University
  摘要：Cloud services have grown rapidly in recent years as a new form of service, but there exists scant research on the competition and service offering strategies of cloud service providers. We study these strategic choices by considering a setting where an incumbent cloud service provider may offer two service classes (premium and standard) and an entrant provider may offer the standard service. We analyze two competitive strategies the incumbent provider: (a) deterring competitor entry, and (b) ...
• Advertising Competition on the Internet: Operational and Strategic Considerations AI翻译
  作者：Liu, Dengpan; Mookerjee, Vijay
  作者单位：Tsinghua University; University of Texas System; University of Texas Dallas
  摘要：The emerging click-based pricing models for Internet advertising provide the firm with two possible decision processes to manage an advertising campaign, namely, spending-based and traffic-based. The spending-based process starts with the spending budget and determines the traffic accordingly, whereas the traffic-based process starts with a target level of traffic and determines the spending budget accordingly. We consider a duopoly where two electronic retailing firmsthat compete for customer...
• A Behavioral Remedy for the Censorship Bias AI翻译

  摘要：Existing evidence suggests that managers exhibit a censorship bias: demand beliefs tend to be biased low when lost sales from stockouts are unobservable (censored demand) compared to when they are observable (uncensored demand). We develop a non-constraining, easily implementable behavioral debias technique to help mitigate this tendency in demand forecasting and inventory decision-making settings. The debiasing technique has individuals record estimates of demand outcomes (REDO): participants...
