摘要:We study a capacity sizing problem in a service system that is modeled as a single-class queue with multiple servers and where customers may renege while waiting for service. A salient feature of the model is that the mean arrival rate of work is random (in practice this is a typical consequence of forecasting errors). The paper elucidates the impact of uncertainty on the nature of capacity prescriptions, and relates these to well established rules-of-thumb such as the square-root safety staff...

摘要:It has become widely accepted that information technology (IT) has had a profound influence on market transactions, with lower search costs for buyers often considered the key to lower prices and higher consumer welfare. However, sellers also use online channels to search for buyers whose product preferences and valuations match the sellers' offerings, and limited research has examined the impact of IT on sellers' search strategies or associated market outcomes. In this study, we investigate h...

摘要:Risk measurement for derivative portfolios almost invariably calls for nested simulation. In the outer step, one draws realizations of all risk factors up to the horizon, and in the inner step, one reprices each instrument in the portfolio at the horizon conditional on the drawn risk factors. Practitioners may perceive the computational burden of such nested schemes to be unacceptable and adopt a variety of second-best pricing techniques to avoid the inner simulation. In this paper, we questio...

摘要:Prior studies suggest that investors have limited attention. Tests of the inattention hypothesis have been performed in the context of relatively small corporate events, particularly earnings announcements. Presumably, large corporate events would always attract sufficient investor attention. However, we find evidence indicating that inattention affects investors' information processing even in the context of one of the largest and most important corporate events-merger announcements. More spe...

摘要:This paper develops an economic theory of the costs and benefits of corporate culture-in the sense of shared beliefs and values-in order to study the effects of culture clash in mergers and acquisitions. I first use a simple analytical framework to show that shared beliefs lead to more delegation, less monitoring, higher utility (or satisfaction), higher execution effort (or motivation), faster coordination, less influence activities, and more communication, but also to less experimentation an...

摘要:In this paper, we consider a class of two-stage stochastic optimization problems arising in the protection of vital arcs in a critical path network. A project is completed after a series of dependent tasks are all finished. We analyze a problem in which task finishing times are uncertain but can be insured a priori to mitigate potential delays. A decision maker must trade off costs incurred in insuring arcs with expected penalties associated with late project completion times, where lateness p...

摘要:Online personalization services belong to a class of economic goods with a no free disposal (NFD) property where consumers do not always prefer more services to less because of the privacy concerns. These concerns arise from the revelation of information necessary for the provision of personalization services. We examine vendor strategies in a market where consumers have heterogeneous concerns about privacy. In successive generalizations, we allow the vendor to offer a fixed level of personali...

摘要:Many retailers designate one national brand manufacturer in each product category as a category captain to help manage the entire category. A category captain may perform demand-enhancing services such as better shelf arrangements, shelf-space management, and design and management of in-store displays. In this paper, we examine when and why a retailer may engage one manufacturer exclusively as a category captain to provide such service and the implications. We find that demand substitutability...

摘要:This paper studies two fundamentally distinct approaches to opening a technology platform and their different impacts on innovation. One approach is to grant access to a platform and thereby open up markets for complementary components around the platform. Another approach is to give up control over the platform itself. Using data on 21 handheld computing systems (1990-2004), I find that granting greater levels of access to independent hardware developer firms produces up to a fivefold acceler...

摘要:Social learning describes any situation in which individuals learn by observing the behavior of others. In the real world, however, individuals learn not just by observing the actions of others but also from seeking advice. This paper introduces advice giving into the standard social-learning experiment of Celen and Kariv (Celen, B., S. Kariv. 2005. An experimental test of observational learning under imperfect information. Econom. Theory 26(3) 677-699). The experiments are designed so that bo...
