摘要：The United States has the highest rate of obesity in the world. To help address this problem, social support is gaining credibility as a powerful tool to facilitate weight loss because it can affect people's behavior. Although social support has long been recognized for its effectiveness in promoting health, we argue, in this study, that social support may not always lead to good outcomes. Specifically, we differentiate between support providers and support seekers, and examine whether providi...

摘要：We empirically investigate the pattern of where heart attack patients are transferred between hospitals. Using 2011 Florida State Emergency Department and Inpatient Databases, we demonstrate the relative importance of three key factors in determining transfer destinations: (1) the distance between sending and receiving hospitals, (2) publicly reported quality measures of receiving hospitals, and (3) the relationship between sending and receiving hospitals as indicated by whether they are affil...

摘要：Traditionally, online retailers have acted as product resellers. Recently, these retailers have also started to serve as online marketplaces by providing a platform to directly connect sellers with buyers. Over and above re-shaping the traditional e-commerce market, conventional wisdom suggests that this new format will mitigate the double-marginalization effect and benefit both the intermediary and suppliers through a revenue sharing scheme. However, we find that upstream competition between ...

摘要：With the rise of the Internet economy, an increasing number of firms are offering their core products through online platforms, but retail add-ons directly to consumers. Meanwhile, many online platforms have also started adopting the agency (model) contract, where the upstream firms decide the retail prices of products while the downstream platforms take a predetermined cut from each sale. This study examines the interaction between an upstream firm's add-on strategy and a downstream online pl...

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...

摘要：Optimizing advertising budget allocation in the luxury fashion industry is an important problem. In this study, motivated by real-world practices, we consider a luxury fashion firm serving a conspicuous market consisting of two groups of consumers who influence one another. We investigate the optimal customer portfolios and budget allocation problem using the mean-variance (MV) framework. Under the basic model in which all budget must be spent, we identify different scenarios and propose an al...

摘要：Firms can enhance the reliability of their supply through process improvement and overproduction. In decentralized supply chains, however, these mitigating actions may be the supplier's responsibility yet are often not contractible. We show that wholesale price contracts, despite their simplicity, can perform well in inducing reliable supply, and we identify when and why they perform well. This could explain the widespread use of wholesale price contracts in business settings with unreliable s...

摘要：We consider service systems where customers do not know the distribution of uncertain service quality and cannot estimate it fully rationally. Instead, they form their beliefs by taking the average of several anecdotes, the size of which measures their level of bounded rationality. We characterize the customers' joining behavior and the service provider's pricing, quality control, and information disclosure decisions. Bounded rationality induces customers to form different estimates of the ser...

摘要：We study the problem where independent operators of queueing systems cooperate to generate a win-win solution through capacity transfer among each other. We consider two types of costs: the congestion cost in the queueing system and the capacity transfer cost, and two types of queueing systems: M/M/1 and M/M/s. Service rates are considered to be capacities in M/M/1 and are assumed to be continuous, while numbers of servers are capacities in M/M/s. For the capacity transfer problem in M/M/1, we...

摘要：Prototyping allows firms to evaluate the technical feasibility of alternative product designs and to better estimate their costs. We study a collaborative prototyping scenario in which a manufacturer involves a supplier in the prototyping process by letting the supplier make detailed design choices for critical components and provide prototypes for testing. While the supplier can obtain private information about the costs, the manufacturer uses target costing to gain control over the design ch...
