摘要：Health information exchanges (HIEs) are expected to improve poor information coordination in emergency departments (EDs); however, whether and when HIEs are associated with better operational outcomes remains poorly understood. In this work, we study HIE and length of stay (LOS) relationship using a large dataset from the Healthcare Cost and Utilization Project consisting of about 7.4 million treat-and-release visits made to 63 EDs in Massachusetts. Overall, we find that HIE adoption is associ...

摘要：We solve a variation of a classic make-to-stock inventory problem introduced by Gavish and Graves. A machine is dedicated to a single product whose demand follows a stationary Poisson distribution. When the machine is on, items are produced one at a time at a fixed rate and placed into finished-goods inventory until they are sold. In addition, there is an expense for setting up the machine to begin a production run. Our departure from Gavish and Graves involves the handling of unsatisfied dema...

摘要：We have four goals in this study. First, we chronicle China's history of technology and manufacturing before the Industrial Revolution. This history of monumental developments is scattered in dozen of books and hundreds of articles, but it is not available in a concise form. Although, this history is relevant to all disciplines in social sciences, science, and technology, it is most relevant to the discipline this journal represents. Second, we analyze the role of exports in improving quality ...

摘要：Multinational automakers tend to be biased toward adapting products designed for their primary markets to emerging or secondary markets. The preference for such adapted product design (APD) approach arises from reduced costs associated with product design and development. However, the growing importance of emerging markets combined with the recognition of their idiosyncratic needs have led automakers to consider an alternative product development approach that simultaneously incorporates the n...

摘要：We experimentally study first-price split-award auction formats as they can be found in procurement markets where suppliers have economies of scale. Our analysis includes sequential and combinatorial auctions, which allow for bids on the package of two shares and single shares. We derive equilibrium predictions as hypotheses for bidder behavior in our laboratory experiments. These equilibrium predictions help explain important patterns in our experimental results. The combinatorial first-price...

摘要：This paper studies how to design service outsourcing contracts to ensure fast, quality services from an independent service provider. The outsourcer does not have perfect information about the service provider's capacity cost (i.e., cost of providing fast service) and quality cost (i.e., cost of achieving a high quality level). Moreover, the two unknown costs may be positively, or negatively, correlated with each other. We solve for the outsourcer's optimal outsourcing contract, and show that ...

摘要：Through analytical modeling and a numerical study grounded in observations from automotive remanufacturing, this study examines seeding-selling new products as remanufactured at the start of a new product's lifecycle-in order to increase core recovery quantities, to allow firms to start efficient remanufacturing earlier, and to fulfill demand for remanufactured products throughout the product's lifecycle. Though seeding has received little attention in the academic literature, many durable goo...

摘要：This paper develops a dyadic supply chain model with one buyer who contracts the manufacturing of a new product to a supplier. Due to the lack of experience in manufacturing, the extent of supply risk is unknown to both the buyer and supplier before the time of contract. However, after the contract is accepted, the supplier may invest in a diagnostic test to acquire information about his true reliability, and use this information when deciding on a process improvement effort. Using this settin...

摘要：Manufacturers and distributors of expensive implants and other medical supplies often require buyers to sign non-disclosure agreements treating all information concerning negotiated prices as trade secrets. Such agreements make it difficult for hospitals to obtain accurate pricing benchmarks. To save on procurement costs and to obtain pricing information, most hospitals in the United States join group purchasing organizations (GPOs). GPOs are believed to lower procurement costs by aggregating ...

摘要：We consider a decentralized supply chain (DSC) under resale price maintenance (RPM) selling a limited-lifetime product to forward-looking customers with heterogeneous valuations. When customers do not know the inventory level, double marginalization under RPM leads to a higher profit and aggregate welfare than without RPM under a two-part tariff contract (TT). Both RPM and TT profits are higher and aggregate welfare is lower than in a centralized supply chain (CSC). When customers know the inv...
