  摘要：Vaccination is an effective way to prevent an epidemic. It results in immunity for the vaccinated individuals, but it also reduces the infection pressure for unvaccinated people. Thus people may actually escape infection without being vaccinated: the so-called herd effect. We analytically study the relation between the herd effect and the vaccination fraction for the seminal SIR compartmental model, which consists of a set of differential equations describing the time course of an epidemic. We...
• Joint Control of Emissions Permit Trading andProduction Involving Fixed and Variable Transaction Costs AI翻译

  摘要：The use of permit markets to mitigate harmful emissions is on the rise. When participating in such a market, an emitting firm needs to acquire from it permits that cover emissions resulting from production. Thus, it has to simultaneously cope with fluctuating permit prices and random demand, and also juggle between the activities of permit trading and permit-consuming production. We shed light on this complex dynamic control problem, while confronting difficulties brought on by fixed as well a...
• Production Process Moves: Template Use and the Need to Adapt AI翻译

  摘要：We use a behavioral experiment to examine whether the use of templates facilitates or hinders a faster production ramp-up after a process move. If the environment in which a template is applied closely resembles the environment in which the template was developed, template use promotes knowledge transfer, resulting in increased performance while ramping up the process. However, when the environments at the origin and destination of the template differ, these benefits do not occur. We further s...
• Approximation Approaches for Inventory Systems with General Production/Ordering Cost Structures AI翻译

  摘要：The production/ordering cost structure is fundamental to determining an optimal inventory control policy. For example, it is well known that a base-stock policy is optimal for inventory systems with linear production costs, whereas an (s,S) policy is optimal if both linear and fixed costs exist. However, many of the cost structures that have arisen from the practice are quite complex and make the optimal policies too complicated for managers to implement. In this study, we propose several easy...
• Research in Operations Management and Information Systems Interface AI翻译

  摘要：Owing to its multidisciplinary nature, the operations management (OM) and information systems (IS) interface distinguishes itself from the individually focused perspective of both fields. The number and depth of contributions in this department can help both disciplines advance to better address important theoretical and practical challenges of the business world. In this paper, we study the characteristics of problems at the interface between OM and IS, and review past work that has been inst...
• The Perils of Sharing Information in a Trade Association under a Strategic Wholesale Price AI翻译
  作者：Shamir, Noam; Shin, Hyoduk
  作者单位：Tel Aviv University; University of California System; University of California San Diego
  摘要：We study the incentives of a group of retailers, organized as a trade association and sourcing the product from a single manufacturer, to exchange private forecast information. We compare two widely used policies by the trade association in practice: exclusionary information exchange and non-exclusionary information exchange. Under the exclusionary policy, only retailers who contribute their private information are exposed to the pool of shared information, whereas under the non-exclusionary p...
• Product Recall Decisions in Medical Device Supply Chains: A Big Data Analytic Approach to Evaluating Judgment Bias AI翻译
  作者：Mukherjee, Ujjal Kumar; Sinha, Kingshuk K.

  摘要：This study investigates judgment bias (under-reaction or over-reaction) in product recall decisions by firms when they respond to adverse event reports generated by users of their products. We develop an integrative theoretical framework for identifying the sources of judgment bias in product recall decisions. We analyze user-generated reports (big and unstructured data) on adverse events related to medical devices, using a combination of econometric and predictive analytic methods. We find th...
• Dynamic Pricing with Service Unbundling AI翻译
  作者：Song, Boqian; Li, Michael Z. F.

  摘要：In this study, we investigate unbundling when a firm dynamically prices a basic service, while separating the sale of a fixed-price add-on. We characterize the optimal dynamic unbundling pricing policy and investigate its structural properties. We find that the value function with unbundling increases in the degree of dependence between consumers' reservation prices for basic service and add-on. However, there are no similar monotonicity properties for the optimal price of the basic service. F...
• Immediate and Long-Term Benefits of In-Store Return Experience AI翻译
  作者：Ertekin, Necati
  作者单位：Santa Clara University
  摘要：This study contributes to the understanding of customer relationship management by assessing how an in-store customer return experience can influence customer exchange behavior and satisfaction during a return event, and customer repurchase behavior following a return event. Exchanges, satisfaction, and repurchases are potential customer relationship management outcomes that may contribute to customer lifetime value. We empirically examine these outcomes with respect to two store labor factors...
• Demand and Revenue Impacts of an Opaque Channel: Evidence from the Airline Industry AI翻译
  作者：Granados, Nelson; Han, Kunsoo; Zhang, Dan

  摘要：Over time, opaque intermediaries, such as Hotwire and Priceline.com, have become an established distribution channel for the travel industry. We use a market response model and a dataset of economy class reservations from a major international airline to empirically examine the demand and cannibalization effects of the opaque channel. We find that: (1) the impact of the opaque channel on total demand is positive and significant in markets with high levels of competition; and (2) overall, the o...
