  摘要：Our study investigates the effects of introducing performance-based incentives in a competitive health care market. We consider a market in which a payer applies a performance-based compensation contract to two competing hospitals. We use G/G/m queuing dynamics to describe the patient care process and include information asymmetry between the payer and the hospitals regarding the hospital operating costs. Our paper is the first to study the performance-based contracting problem in a health car...
• Modeling Yellow and Red Alert Durations for Ambulance Systems AI翻译

  摘要：Emergency systems are designed to almost always have enough capacity to respond to emergencies. However, capacity shortage periods do occur and these systems need to recover quickly. In this study, we apply queueing models and study whether it is better for an emergency system to add or to expedite servers, in order to quickly recover from a capacity shortage period. We focus on emergency medical service (EMS) systems and use Erlang loss models to study Red Alerts (when all ambulances are busy...

  摘要：In this study, we focus on the maintenance of an intrusion detection system (IDS) that attempts to discriminate between benign and malicious traffic arriving at a firm. An attack is more likely to successfully harm the firm if the ability of its IDS to discriminate between malicious and benign traffic is low, implying loopholes or vulnerabilities in the firm's security. A novel aspect of this study is the modeling of both continuous degradation in system discrimination ability (drift) and the ...
• To Thine Own Self Be True: Asymmetric Information in Procurement Auctions AI翻译

  摘要：As procurement auctions increasingly move to digital platforms, more data and information is available (or can be made available) to bidders. Despite this trend, relatively little is known about the impact of information asymmetries in these settings. We investigate two such differences in first-price sealed-bid reverse auctions with a common value. In a design that mirrors real construction procurement auctions, our laboratory experiment tests the impact of the precision of a bidder's cost es...
• Generating Competitive Intelligence with Limited Information: A Case of the Multimedia Industry AI翻译

  摘要：Competitive intelligence is a critical component of developing and implementing organizational strategies. Although firms may obtain aggregate market-level competitive information, resource allocation decisions such as inventory management or capacity planning are made at the individual product-firm-market level. Acquiring such disaggregated information about competitors across various products and markets poses significant challenges, including integrating data from different (and conflicting...
• Pricing Joint Sales and Rentals: When are Purchase Conversion Discounts Optimal? AI翻译

  摘要：Product sales and rentals often occur in parallel, allowing customers to choose their preferred option. In settings where consumers face significant value uncertainty, rentals also provide a mechanism for consumers to discover whether they like a product. For some products, such as movies and books, the rental option may yield a significant proportion of the utility associated with ownership. The convenience of renting products in digital forms (e.g., e-books) makes the managerial challenge of...
• Do E-Waste Laws Create Behavioral Spillovers? Quasi-Experimental Evidence from California AI翻译

  摘要：Many governing bodies have launched efforts to shape the operations of manufacturers, administration of civic entities, and behavior of individuals to limit waste generation. Typically, such efforts commence with the enactment of targeted legislations that create operational changes (e.g., recycling fees, collection centers) to the waste collection and disposal processes. For example, over 25 states in the United States have enacted legislations that aim to properly dispose used electronic and...
• Optimal Learning Algorithms for Stochastic Inventory Systems with Random Capacities AI翻译

  摘要：We propose the first learning algorithm for single-product, periodic-review, backlogging inventory systems with random production capacity. Different than the existing literature on this class of problems, we assume that the firm has neither prior information about the demand distribution nor the capacity distribution, and only has access to past demand and supply realizations. The supply realizations are censored capacity realizations in periods where the policy need not produce full capacity...
• Horizontal Mergers under Yield Uncertainty AI翻译
  作者：Xiao, Yixuan

  摘要：We study a horizontal merger in an oligopolistic market in which firms compete on production quantities. Each firm has its own in-house manufacturing facility, and the production is subject to random yield. After the consolidation of two firms, the merged entity can use both manufacturing facilities that belong to the merging firms. It is well known that diversification can reduce the aggregate supply uncertainty of a firm, but this diversification benefit has not been explored in a merger ana...
• Vaccine Procurement Contracts for Developing Countries AI翻译

  摘要：In recent years, several Global Health Organizations (GHOs) have experimented with market-based procurement contracts to encourage pharmaceutical companies to bring late-stage vaccines to developing-country markets. Pharmaceutical companies often find such markets financially unattractive because the opportunity cost of capacity commitment is high, developing countries have limited ability to pay, and demand is uncertain. A contract design recently implemented by one GHO offers the manufacture...
