摘要：Recommender systems are becoming a salient part of many e-commerce websites. Much research has focused on advancing recommendation technologies to improve accuracy of predictions, although behavioral aspects of using recommender systems are often overlooked. In our studies, we explore how consumer preferences at the time of consumption are impacted by predictions generated by recommender systems. We conducted three controlled laboratory experiments to explore the effects of system recommendati...

摘要：We investigate the impact of outsourcing on the long-term market performance of the firm. Outsourcing initiatives vary in terms of uncertainty in business requirements, complexity of coordination between the outsourcing firm and provider, and the consequent choice of the governing contract (fixed or variable price). Using theories from institutional economics, strategy, and information systems, we argue that firms pursuing large-scale, fixed price outsourcing, which are characterized by lower ...

摘要：Interactive online decision aids often employ User-decision aid dialogues as forms of user-system interaction to help construct and elicit users' attribute preferences about a product type. This study extends prior research on online decision aids by investigating the effects of a decision aid's user-system interaction mode (USIM), which can be either user-guided or system-controlled, on users' effort-related (number of iterations of using the aid and perceived cognitive effort expended in usi...

摘要：Digital technologies have made networks ubiquitous. A growing body of research is examining these networks to gain a better understanding of how firms interact with their consumers, how people interact with each other, and how current and future digital artifacts will continue to alter business and society. The increasing availability of massive networked data has led to several streams of inquiry across fields as diverse as computer science, economics, information systems, marketing, physics,...

摘要：This article investigates the economic consequences of data errors in the information flows associated with business processes. We develop a process modeling-based methodology for managing the risks associated with such data errors. Our method focuses on the topological structure of a process and takes into account its effect on error propagation and risk mitigation using both expected loss and conditional value-at-risk risk measures. Using this method, optimal strategies can be designed for c...

摘要：Information systems must be used effectively to obtain maximum benefits from them. However, despite a great deal of research on when and why systems are used, very little research has examined what effective system use involves and what drives it. To move from use to effective use requires understanding an information system's nature and purpose, which in turn requires a theory of information systems. We draw on representation theory, which states that an information system is made up of sever...

摘要：Combinatorial auctions have been suggested as a means to raise efficiency in multi-item negotiations with complementarities among goods because they can be applied in procurement, energy markets, transportation, and the sale of spectrum auctions. The combinatorial clock (CC) auction has become very popular in these markets for its simplicity and for its highly usable price discovery, derived by the use of linear prices. Unfortunately, no equilibrium bidding strategies are known. Given the impo...

摘要：In recent years, with the emergence and growth of illegal file sharing on the Internet, individual piracy of digital goods, i.e., consumers making illegal copies on their own rather than relying on purchasing copies from commercial pirates, has stirred substantial controversy. Threatened by this growth, the information goods industry took legal action by suing the file sharing peer-to-peer networks and the consumers who illegally share copyrighted material on these networks. In this paper we d...

摘要：Combinatorial auctions are used in a variety of application domains, such as transportation or industrial procurement, using a variety of bidding languages and different allocation constraints. This flexibility in the bidding languages and the allocation constraints is essential in these domains but has not been considered in the theoretical literature so far. In this paper, we analyze different pricing rules for ascending combinatorial auctions that allow for such flexibility: winning levels ...
