摘要：Previous research into consumer choice of service channels studied the impact of online access as an addition to conventional service. Here, we study the impact of a compulsory migration to an online channel. We exploit a natural experiment in the implementation of a new federal government service to identify the causal effect of access channel on consumer choice. The government served western states through the Internet and telephone at all times. However, for the first 10 days, the governmen...

摘要：With the nearly instantaneous dissemination of information in the modern era, policies regarding the disclosure of sensitive information have become the focus of significant discussion in several contexts. The fundamental debate centers on trade-offs inherent in disclosing information that society needs, but that can also be used for nefarious purposes. Using information security as a research context, our empirical study examines the adoption of software vulnerabilities by a population of att...

摘要：Taking advantage of the opportunities created by the price adjusted performance improvement in information technology (IT) depends in part on the ability of IT capital to substitute for other inputs in production. Studies in the information systems literature and most economics training examining the substitution of IT capital for other inputs use the Allen elasticity of substitution (AES). We present a less-well-known measure for the elasticity of substitution, the Morishima elasticity of sub...

摘要：Can location-based mobile promotion (LMP) trigger contemporaneous and delayed sales purchases? As mobile technologies can reach users anywhere and anytime, LMP becomes a promising new channel. We unravel the dynamic sales impact of LMP on the basis of a randomized field experiment with 22,000 mobile users sponsored by one of the largest mobile service providers in the world. Our identification strategy is to gauge the marginal increases in consumer purchases of the geo-fenced treatment group o...

摘要：Information security (IS) threats are increasingly pervasive, and search engines are being used by the public as the primary tool for searching for relevant information. This research investigates the following two questions: (1) How can different IS threats be characterized and distinguished in terms of their risk characteristics? and (2) how are risk characteristics related to public searches for information on IS threats? Applying psychometric analysis, our analyses of survey data first sho...

摘要：Research findings on how participation in social networking sites (SNSs) affects users' subjective well-being are equivocal. Some studies suggest a positive impact of SNSs on users' life satisfaction and mood, whereas others report undesirable consequences such as depressive symptoms and anxiety. However, whereas the factors behind the positive effects have received significant scholarly attention, little is known about the mechanisms that underlie the unfavorable consequences. To fill this ga...

摘要：With the emergence of social media and Web 2.0, broadcasting in the online environment has evolved into a new form of marketing due to the much broader reach enabled by information technology. This paper quantifies the effect of artists' broadcasting activities on a well-known social media site for music, MySpace, on music sales. We employ a panel vector autoregression model to investigate the interrelationship between broadcasting promotions in social media and music sales, while controlling ...

摘要：Business analytics has evolved from being a novelty used by a select few to an accepted facet of conducting business. Recommender systems form a critical component of the business analytics toolkit and, by enabling firms to effectively target customers with products and services, are helping alter the e-commerce landscape. A variety of methods exist for providing recommendations, with collaborative filtering, matrix factorization, and association-rule-based methods being the most common. In th...

摘要：We explore how Red Queen competition is increasing the competitive premium on evolvable information systems (IS). Ephemeral market advantage coupled with relentless innovation spawning trends such as the Internet-of-Things and additive manufacturing are amplifying the importance of evolvable systems across all industries. We discuss uncharted theoretical and empirical territory for IS research on evolvable systems. The elusiveness of some of these phenomena to other disciplines offers a unique...

摘要：Social networks have been shown to affect health. Because online social networking makes it easier for individuals to interact with experientially similar others in regard to health issues and to exchange social support, there has been an increasing effort to understand how networks function. Nevertheless, little attention has been paid to how these networks are formed. In this paper, we examine the driving forces behind patients' social network formation and evolution. We argue that patients'...
