摘要：Motivated by the ever-growing complexity of projects and the consistent trend of outsourcing of individual tasks or components, we study the contract-design problem faced by a firm (or organization) for executing a project consisting of multiple tasks, each of which is performed by an individual contractor whose efforts (work-rates) are not observable. While the contractors incur costs continuously during the course of their tasks, the firm realizes its reward or revenue only when the entire p...

摘要：There is extensive academic research examining why firms adopt environmental management practices (EMPs), reflecting an increasing focus on firm environmental activity in research and practice. However, there is little understanding of why firms vary within and across industries in the number of EMPs they adopt (EMP adoption). In this study, we seek to identify the sources of variation and quantify the relative importance of each source. Using Hierarchical Linear Modeling (HLM) and a 12-year p...

摘要：The purpose of this paper is to investigate the learning from rare events and the knowledge management process involved, which presents a significant challenge to many organizations. This is primarily attributed to the inability to interpret these events in a systematic and rich manner, which this paper seeks to address. We start by summarizing the relevant literature on humanitarian operations management (HOM), outlining the evolution of the socio-technical disaster lifecycle and its relation...

摘要：This paper studies the effect of customer abandonment in the economic optimization of a service facility. Specifically, we consider how to jointly set the price and service capacity in order to maximize the steady-state expected profit, when the system is subject to customer abandonment and the price is paid only by customers that eventually receive service. We do this under the assumption that there is a high rate of prospective customer arrivals. Our analysis reveals that the economically op...

摘要：We study the effects associated with overconfidence in distribution channels, where overconfidence is defined as a decision maker's cognitive bias in perceiving the expected outcome of an uncertain event as more certain than it likely is. Although overconfidence bias always leads to a lower expected profit for a centralized channel, we find that overconfidence can in fact enhance the performance of a decentralized channel comprising one overconfident manufacturer and retailer. That is, overcon...

摘要：This study models a multi-player environment consisting of a grid operator responsible for meeting electricity demands, a photovoltaic (PV) manufacturer, customers who might install (solar) PV systems, and a regulator who must set an optimal feed-in tariff (FIT). The grid operator must meet exogenous electricity demand and also buy back all electricity (produced by PV systems) at the FIT set by the regulator. Customers decide whether or not to invest in a PV system. Adoption rates affect the m...

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：Firms in advanced economies are increasingly outsourcing software and technology development as well as other knowledge work to a worldwide supply base. Standard economic and learning models predict that focal firms should outsource either all or none of a particular activity unless extra resources are required during cyclical demand peaks or access is needed to some tightly appropriable intellectual property. However, recent evidence shows that, even when these exceptions do not apply, many f...

摘要：The present study investigates the benefit of joint decision making regarding whole blood collection and platelet production at a blood center. We consider a blood center that faces two types of platelet demands, differing in their freshness requirements and shortage penalty costs. We fully characterize the structure of the optimal policy regarding whole blood collection, platelet production, and inventory issuing, rationing and disposal. We find that the optimal platelet production quantity i...

摘要：In recent years, the drive to contain health care costs has increased scrutiny of the traditional mode of delivering primary care where a patient is treated only by his primary care physician. In particular, greater reliance on non-physician providers has been suggested as a lower-cost alternative to the traditional set-up. In this study, we consider a homogeneous patient panel treated by a solo primary care physician and develop a new model of patient health dynamics in which the health state...
