摘要：In this paper, we develop two models for the valuation-of information technology (IT) investment projects using the real options approach. The IT investment projects discussed in this paper are categorized into development and acquisition projects, depending upon the time it takes to start benefiting from the IT asset once the decision to invest has been taken. The models account for uncertainty both in the costs and benefits associated with the investment opportunity. Our stochastic cost func...

摘要：W e present a framework and empirical estimates that quantify the economic impact of increased product variety made available through electronic markets. While efficiency gains from increased competition significantly enhance consumer surplus, for instance, by leading to lower average selling prices, our present research shows that increased product variety made available through electronic markets can be a significantly larger source of consumer surplus gains.. One reason for increased produc...

摘要：A growing body of research documents the role that organizational learning plays in improving firm performance over time. To date, however, this literature has given limited attention to the effect that the internal structure of the firm c an have on generating differences in these learning rates. This paper focuses on the degree to which interdependence-and in particular one structural characteristic that generates interdependence, vertical integration-affects organizational learning. Firms f...

摘要：The Internet is growing rapidly in terms of both use and infrastructure. Unfortunately, demand is outpacing the capacity of the infrastructure, as evidenced by unacceptably long response times. To support current load and further growth, we must address this problem. Several caching strategies have been proposed in the literature; many have been implemented to improve the quality of service on the Web. In this paper, we identify the main causes of delay on the Web, and provide a review of the ...

摘要：Research in organizational learning has demonstrated processes and occasionally performance implications of acquisition of declarative (know-what) and procedural (know-how) knowledge. However, considerably less attention has been paid to learned characteristics of relationships that affect the decision to seek information from other people. Based on a review of the social network, information processing, and organizational learning literatures, along with the results of a previous qualitative ...

摘要：We propose an evolutionary metaheuristic for multiobjective combinatorial optimization problems that interacts with the decision maker (DM) to guide the search effort toward his or her preferred solutions. Solutions are presented to the DM, whose pairwise comparisons are then used to estimate the desirability or fitness of newly generated solutions. The evolutionary algorithm comprising the skeleton of the metaheuristic makes use of selection strategies specifically designed to address the mul...

摘要：Previous work on the solution to analytical electronic customer relationship management (eCRM) problems has used either data-mining (DM) or optimization methods, but has not combined the two approaches. By leveraging the strengths of both approaches, the eCRM problems of customer analysis, customer interactions, and the optimization of performance metrics (such as the lifetime value of a customer on the Web) can be better analyzed. In particular, many eCRM problems have been traditionally addr...

摘要：We trace the history of revenue management in an effort to illustrate a successful e-commerce model of dynamic, automated sales. Our discourse begins with a brief overview of electronic distribution as practiced in the airline industry, emphasizing the fundamental role of central reservation and revenue management systems. Methods for controlling the sale of inventory are then introduced along with related techniques for optimization and forecasting. Research contributions and areas of signifi...

摘要：This paper compares how managers value knowledge from internal and external sources. Although many theories account for favoritism toward insiders, we find that preferences for knowledge obtained from outsiders are also prevalent. Two complementary case studies and survey data from managers demonstrate the phenomenon of valuing external knowledge more highly than internal knowledge and reveal some mechanisms through which this process occurs. We found evidence that the preference for outsider ...

摘要：The Internet's computational power and flexibility have made auctions a widespread and integral part of both consumer and business markets. Though online auctions are a multibillion dollar annual activity, with a growing variety of sophisticated trading mechanisms, scientific research on them is at an early stage. This paper analyzes the current state of management science research on online auctions. It develops a broad research agenda for issues such as the behavior of online auction partici...
