• Linking Quality with Social and Financial Performance: A Contextual, Ethics-Based Approach AI翻译
  作者：Sila, Ismail
  作者单位：Near East University
  摘要：The objectives of this study are to test the relationships among total quality management (TQM) practices, corporate social performance (CSP), and financial and market performance (FMP); and to determine the moderating effects of two contextual factors-country and sector-on these relationships through the lenses of several theories, including stakeholder theory, integrative social contracts theory (ISCT), and legitimacy theory. Using data from the various sectors of the economies of two develo...

  摘要：We study a joint implementation of price- and availability-based product substitution to better match demand and constrained supply across vertically differentiated products. Our study is motivated by firms that utilize dynamic pricing as well as customer upgrades, as ex ante and ex post mechanisms, respectively, to mitigate inventory mismatches. To gain insight into how offering product upgrades impacts optimal price selection, we formulate a multiple period, nested two-stage model where the ...
• Reservation Policies in Queues: Advance Deposits, Spot Prices, and Capacity Allocation AI翻译

  摘要：At firms such as restaurants, customers either make reservations in advance or join queues on the spot. Reservation holders may not show up, and walk-ins have to wait. Using a game-theoretic model between the firm and customers, this paper studies the following: (i) reservation deposits and service prices, and (ii) capacity allocation between reservations and walk-ins. We have three main results: (i) When reservation no-shows lead to wasted capacity that cannot be reallocated, the firm should ...
• Pricing Diagnosis-Based Services When Customers Exhibit Sunk Cost Bias AI翻译

  摘要：Significant evidence has emerged that consumers are boundedly rational and display a sunk cost bias when making decisions. Moreover, customers may display dynamically inconsistent beliefs about the extent to which they will discount sunk costs. We evaluate the impact of sunk cost bias and dynamically inconsistent preferences on commonly used pricing schemes in a service setting with diagnosis and treatment phases. Using a two-part tariff pricing scheme, a monopolist service provider can achiev...
• Sentiment Manipulation in Online Platforms: An Analysis of Movie Tweets AI翻译

  摘要：Online platforms are prone to abuse and manipulations from strategic parties. For example, social media and review websites suffer from sentiment manipulations, manifested in the form of opinion spam and fake reviews. The consequence of such manipulations is the deterioration of information quality as well as loss in consumer welfare. We study one of movie studios' operation activities, sentiment manipulation, in the context of movie tweets. Using the movie release and movie studios' earning a...
• On Sourcing Decisions with Stochastic Supplier Reliability and Stochastic Demand AI翻译
  作者：Yan, Xiaoming

  摘要：This note complements the study of Burke, Carillo and Vakharia (hereafter referred to as BCV model), which investigates the implications of unreliable supplies on a firm's sourcing decisions under uniformly distributed demand. First, I present a sufficient condition under which the optimal quantity ordered from each supplier corresponds to the solution derived as BCV. Second, a heuristics is developed for the BCV model when the sufficient condition is not satisfied, and conduct numerical exper...
• Dynamic Patient Scheduling for Multi-Appointment Health Care Programs AI翻译

  摘要：We investigate the scheduling practices of a multidisciplinary, multistage, outpatient health care program. Patients undergo a series of assessments before being eligible for elective surgery. Such systems often suffer from high rates of attrition and appointment no-shows leading to capacity underutilization and treatment delays. We propose a new scheduling model where the clinic assigns patients to an appointment day but postpones the decision of which assessments patients undergo pending the...
• The Impact of Internal Service Quality on Preventable Adverse Events in Hospitals AI翻译
  作者：Zheng, Sarah; Tucker, Anita L.; Ren, Z. Justin; Heineke, Janelle; McLaughlin, Amy; Podell, Aubrey L.
  作者单位：Ithaca College; Boston University; Lahey Hospital & Medical Center
  摘要：Provision of safe, timely care to hospital patients requires services from multiple support departments, such as environmental services and pharmacy. However, few studies have examined the impact of the service quality of internal support departments on clinical performance. The lack of studies linking internal service quality (ISQ) to clinical performance creates a gap in healthcare operations management theory and-from a practice standpoint-might contribute to underinvestment in the quality ...
• A Review of Production and Operations Management Research on Outsourcing in Supply Chains: Implications for the Theory of the Firm AI翻译
  作者：Tsay, Andy A.; Gray, John V.; Noh, In Joon; Mahoney, Joseph T.

  摘要：This paper reviews the state of the art in Productions and Operations Management (POM) academic research regarding outsourcing in supply chain contexts. We first acknowledge the Theory of the Firm (ToF), the venerable and vast body of thought regarding where the firm draws the boundary between what it performs in-house and what it outsources. Despite the clear linkage between outsourcing and POM, the ToF literature is most closely associated with the fields of strategy and economics. This disc...

  摘要：In this study, we propose a stylized Cournot competition model under asymmetric market information and study the formation of producers' informational coalitions. We offer guidance towards how the information service operations can improve the producers' welfare. Our results shed interesting light on farmer producer organizations (FPOs) in their efforts to link farmers in developing economies by integrating market information. To be specific, by focusing on Nash equilibria wherein producers ma...
