  摘要：This study develops a theoretical model and then, using Canadian joint replacement surgery data, empirically tests the relationship between government policies that promote privately funded health care and patients' waiting time in the public health care system. Two policies are tested: one policy allows opt-out physicians to extra-bill private patients, and the other provides public subsidies to private patients. We find that both policies are associated with shorter public waiting time, and ...
• Call Center Delay Announcement Using a Newsvendor-Like Performance Criterion AI翻译

  摘要：The problem of estimating delays experienced by customers with different priorities, and the determination of the appropriate delay announcement to these customers, in a multi-class call center with time varying parameters, abandonments, and retrials is considered. The system is approximately modeled as an M(t)/M/s(t) queue with priorities, thus ignoring some of the real features like abandonments and retrials. Two delay estimators are proposed and tested in a series of simulation experiments....
• When Gray is Good: Gray Markets and Market-Creating Investments AI翻译

  摘要：Gray markets arise when an intermediary buys a product in a lower-priced, often emerging market and resells it to compete with the product's original manufacturer in a higher priced, more developed market. Evidence suggests that gray markets make the original manufacturer worse off globally by eroding profit margins in developed markets. Thus, it is interesting that many firms do not implement control systems to curb gray market activity. Our analysis suggests that one possible explanation lie...

  摘要：While there have been vast discussions on the materialistic benefits of continuous improvement from the Toyota and Honda experiences, the academic literature pays little attention to information sharing. In this study, we construct a dynamic adverse selection model in which the supplier privately observes her production efficiency, and in the contractual duration the manufacturer obtains an informative but imprecise signal regarding this private efficiency. We show that despite the disclosure ...
• Decision Bias in Capacity Allocation Games with Uncertain Demand AI翻译
  作者：Chen, Yefen; Zhao, Xiaobo

  摘要：Existing studies on capacity allocation games have demonstrated that the standard Nash theory exaggerates retailers' tendency of ordering more than they need in the situation of supply shortage. Adding to the results in the literature, our experimental study with consideration of demand uncertainty demonstrates that the standard Nash theory also exaggerates retailers' tendency of telling the truth in their ordering strategy. To account for these systematic biases, based on the quantal response...
• The Role of Discount Vouchers in Market with Customer Valuation Uncertainty AI翻译
  作者：Gao, Fei; Chen, Jian
  作者单位：University of Pennsylvania; Tsinghua University
  摘要：Online discount voucher market In the discount voucher market, customers usually face two types of valuation uncertainty, namely, preference uncertainty and consumption state uncertainty. Preference uncertainty is related to the customer's lack of relevant experience with the merchant, whereas consumption state uncertainty is related to the advance selling nature of the discount voucher mechanism. By taking a comprehensive perspective (i.e., considering revenue management and promotion effect ...
• Research Constituents and Authorship Patterns in the Production and Operations Management Journal AI翻译

  摘要：The Production and Operations Management Society is the largest professional society dedicated to creating and disseminating knowledge in product and process design, operations, and supply chains for the management of manufacturing and services. Its research journal, Production and Operations Management (POM), covers all topics in the discipline and all research paradigms to serve the entire community. Since its inception in 1992, POM has become recognized as a top tier outlet for operations m...
• The Failure of Practical Intuition: How Forward-Coverage Inventory Targets Cause the Landslide Effect AI翻译
  作者：Neale, John J.; Willems, Sean P.
  作者单位：Boston College; Boston University
  摘要：Seasonal demand for products is common at many companies including Kraft Foods, Case New Holland, and Elmer's Products. This study documents how these, and many other companies, experience bloated inventories as they transition from a low season to a high season and a severe drop in service levels as they transition from a high season to a low season. Kraft has termed this latter phenomenon the landslide effect. In this study, we present real examples of the landslide effect and attribute its ...
• Replenishment Policies for Multi-Product Stochastic Inventory Systems with Correlated Demand and Joint-Replenishment Costs AI翻译

  摘要：This study analyzes optimal replenishment policies that minimize expected discounted cost of multi-product stochastic inventory systems. The distinguishing feature of the multi-product inventory system that we analyze is the existence of correlated demand and joint-replenishment costs across multiple products. Our objective is to understand the structure of the optimal policy and use this structure to construct a heuristic method that can solve problems set in real-world sizes/dimensions. Usin...
• The Role of Project and Organizational Context in Managing High-tech R&D Projects AI翻译

  摘要：High-tech organizations often struggle to manage different types of R&D projects. Evidence from research and practice suggests that managers frequently categorize and manage projects based on the extent of change triggered in product, process, technology, and market dimensions. However, this can create challenges in high-tech organizations. This study investigates how high-tech organizations manage R&D projects based on their learning goals. First, we argue for the benefits of categorizing R&D...
