摘要：Virtual communities continue to play a greater role in social, political, and economic interactions. However, how users value information from these communities and how that affects their behavior and future expectations is not fully understood. Stock message boards provide an excellent setting to analyze these issues given the large user base and market uncertainty. Using data from 502 investor responses from a field experiment on one of the largest message board operators in South Korea, our...

摘要：The Internet has provided IS researchers with the opportunity to conduct studies with extremely large samples, frequently well over 10,000 observations. There are many advantages to large samples, but researchers using statistical inference must be aware of the p-value problem associated with them. In very large samples, p-values go quickly to zero, and solely relying on p-values can lead the researcher to claim support for results of no practical significance. In a survey of large sample IS r...

摘要：We examine how network centrality and closure, two key aspects of network structure, affect technology adoption. In doing so, we consider the content of potential information flows within the network and argue that the impact of network structure on technology adoption can be better understood by separately examining its impact from two groups of alters-current and potential adopters. We contend that increased network centrality and closure among current adopters contribute positively to adopt...

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：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：Prior studies on the business value of information technology (IT) mainly focus on the impact of IT investments on productivity and firm profitability. Few have considered its implication on expected and actual product or service quality. This paper fills this gap by investigating the impact of past healthcare IT (HIT) expenditure on the malpractice insurance premium (MIP) and the moderating effect of past HIT expenditure on the relationship between past MIP and current quality of patient care...
