摘要：We study the optimal design of a professional service in a mixed market of customers with heterogeneous skills and capabilities of using such service. Expert customers can avail of the service on their own, whereas amateur customers find it challenging to deploy the service and can only procure the service through an intermediary who resolves the technical issues. We develop a model that captures the essential trade-offs in such settings: heterogeneity in customer expertise, decentralization b...

摘要：Although past studies have found differences in clinical quality outcomes based on patients' insurance type, the extent of these discrepancies, the underlying mechanisms supporting this relationship, and factors that can moderate this effect have not yet been addressed. We seek to fill this gap by studying the relationship between insurance type and clinical quality outcomes using the level of care received, that is, treatment intensity, as a mediator. Using agency theory, we argue that underi...

摘要：Network literature has widely documented that the managerial ties between corporate leaders in two firms can promote their economic exchanges in supply chains, that is, social embeddedness. In this study, we strive to advance this line of inquiry by exploring the dynamics of such socially embedded supply chains, examining whether and when the dissolution of managerial ties between two firms would cause the subsequent termination of their supplier-buyer exchanges. We address this question by di...

摘要：Coupon promotions have been increasingly used with the development of electronic commerce technologies. The post-promotion effects of coupon promotions have been mixed. Using a randomly selected customer sample at a firm that operates a large online classified ads website, we examine the exposure, redemption, and spillover effects of coupon promotions. We find a negative exposure effect and a positive redemption effect. For customers who received coupons but did not redeem them (i.e., exposure...

摘要：The enforcement of ever-stringent regulatory requirements capping emission limits is challenging the traditional operations of various transportation sectors. In maritime transportation, the recent regulation tightening fuel sulfur limits to 0.50%, known as the IMO 2020, has been enforced. There is a flurry of activities by ocean carriers to equip their vessels to comply with this regulation. Although the technical conditions are clear, investment decisions are hard to make due to inevitable u...

摘要：This paper studies the interaction between two key quality management decisions-input conformance quality and inspection policy-and related wholesale and retail prices in a two echelon supply chain. Market demand depends on the retail price as well as the end-product conformance quality, which itself depends on the input quality and the inspection scheme. Consistent with previous empirical findings in the literature, we show that an increase in quality does not always result in higher prices f...

摘要：The extreme demand volatility caused by corona virus 2019 (COVID-19) overwhelmed most preemptive measures enacted by firms to mitigate disruptions in their supply chains. This led to the rapid implementation of reactive measures to provide business continuity. The operations and supply chain management literature has grouped these reactive techniques into those that involve the reconfiguration of firm resources and those that involve changes to its decision-making processes. Unfortunately, lit...

摘要：We consider a two-stage project supply chain with a downstream project firm producing an engineer-to-order (ETO) complex product or a make-to-order (MTO), low-volume, customized industrial product as a project, and an upstream contract supplier supplying a key material to the project. The project faces two uncertainties: project activity time uncertainty and material consumption uncertainty, which may be positively or negatively correlated. In anticipation of these uncertainties, the project f...

摘要：When scheduling the distribution of ordered items from a warehouse to customers, the transportation planning is generally done first and serves as input for planning warehouse operations. Such a sequential approach can lead to substantial inefficiencies when the customer deliveries are restricted by time windows, and the warehouse has limited resources available (both order pickers and space in the staging area). This paper studies the trade-offs between warehouse operations and transportation...

摘要：As financial institutions increasingly offer robo-advisors (RAs) as a service, the empirical evidence on their performance, particularly during market downturns, remains limited. We study the impact of using RAs on investment performance during the 2020 financial crisis caused by the COVID-19 global pandemic. We obtain daily portfolio and transaction data of investors on an online investment platform. Besides making investment decisions by themselves, investors can also leverage an RA system o...
