Multiattribute auctions support automated negotiation insettings where buyers and sellers have valuations for alternateconfigurations of a good, as defined by configurationattributes. Bidders express offers to buy or sell alternateconfigurations by specifying configuration-dependent reserve...

Strategic reasoning is part of our everyday lives: we negotiate prices, bid in auctions, write contracts, and play games. We choose actions in these scenarios based on our preferences, and our beliefs about preferences of the other participants. Game theory provides a rich mathematical framework...

Decision support systems continue to be very popular in business, despite mixed research evidence as to their effectiveness. We hypothesize that what-if analysis, a prominent feature of most decision support systems, creates an “illusion of control” causing users to overestimate its...

In many Internet commerce applications buyers can easily achieve anonymity, limiting what a seller can learn about any buyer individually. However, because sellers need to keep a fixed web address, buyers can probe them repeatedly or pool their information about sellers with the information...

A latent class model for identifying classes of subjects in paired comparison choice experiments is developed. The model simultaneously estimates a probabilistic classification of subjects and the logit models' coefficients relating characteristics of objects to choices for each respective group...

Before the Web, the story of online information services was largely one of over-estimates and unmet expectations. This study examines sustained use and non-use of online services within organizations in a way that overcomes limitations of the traditional approaches that repeatedly led to...

This paper presents both estimation and simulation as optimization problems that differ in the optimization criteria, minimization of a local expected loss for estimation and reproduction of global statistics (semivariogram, histogram) for simulation. An intermediate approach is proposed whereby...

A methodology is presented with examples of the productivity, the staffing required, the resultant productivity, and costs that can be obtained for hospital units that are subject to random work demands such as laboratory, radiology, physical therapy, and nuclear medicine. The methodology...

Like any value-creating staff function, HR departments should operate as a business within a business. Others have focused on the strategy and direction of HR departments. This article examines the next evolution for how HR department organization structure can deliver value based on two...

Robustness has always been one of themost important requirements in the design of the Internet infrastructure. This dissertation takes two directions toward enhancing the robustness of today’s Internet interdomain routing. On one hand, we propose reactive techniques to identify the cause and...
