摘要:Many auctions involve selling several distinct items simultaneously, where bidders can bid on the whole or any part of the lot. Such auctions are referred to as combinatorial auctions. Examples of such auctions include truck delivery routes, industrial procurement, and FCC spectrum. Determining winners in such auctions is an NP-hard problem, and significant research is being conducted in this area. However, multiple-round (iterative) combinatorial auctions present significant challenges in bid...

摘要:Research on group behavior has identified social loafing, i.e., the tendency of members to do less than their potential, as a particularly serious problem plaguing groups. Social Impact Theory (SIT) helps explain social loafing in terms of two theoretical dimensions - the dilution effect (where an individual feels submerged in the group) and the immediacy gap (where an individual feels isolated from the group). In this study, which employed a controlled experiment, we investigated these dimens...

摘要:Growth of Web-based applications has drawn a great number of diverse stakeholders and specialists into the information systems development (ISD) practice. Marketing, strategy, and graphic design professionals have joined technical developers, business managers, and users in the development of Web-based applications. Often, these specialists work for different organizations with distinct histories and cultures. A longitudinal, qualitative field study of a Web-based application development proje...

摘要:This paper offers a systematic exploration of reputation mechanism design in trading environments with opportunistic sellers of commonly known cost and ability parameters, imperfect monitoring of a seller's actions, and two possible seller effort levels, one of which has no value to buyers. The objective of reputation mechanisms in such pure moral hazard settings is to induce sellers to exert high effort as often as possible. I study the impact of various mechanism parameters (such as the gran...

摘要:Given that information technology (IT) security has emerged as an important issue in the last few years, the subject of security information sharing among firms, as a tool to minimize security breaches, has gained the interest of practitioners and academics. To promote the disclosure and sharing of cyber security information among firms, the U.S. federal government has encouraged the establishment of many industry-based Information Sharing and Analysis Centers (ISACs) under Presidential Decisi...

摘要:We consider a new variety of sequential information gathering problems that are applicable for Web-based applications in which data provided as input may be distorted by the system user, such as an applicant for a credit card. We propose two methods to compensate for input distortion. The first method, termed knowledge base modification, considers redesigning the knowledge base of an expert system to best account for distortion in the input provided by the user. The second method, termed input...
