This study uses a multimethod approach to examine how direct communication contributes to matching quality in the context of a peer-to-peer platform for long-term real estate rental properties. We found that longer direct phone communication between the renter (customers) and the host (providers) enables the renter to choose a relatively more unique property within her consideration set. Also, the relationship between direct phone communication and ex post transaction satisfaction is stronger when a relatively more unique alternative is chosen. Direct communication enables consumers to collect additional information that supplements online observable product features and supports choice decisions. It allows consumers to anchor less on the centers of their consideration sets and select those unique alternatives. Consumers can better leverage the breadth ...

Our study leverages the conduit brokerage perspective and the findings of a multiple case study to develop a novel framework of algorithmic conduit brokerage for understanding information dissemination by bots and the design choices that may influence their actions. Algorithmic conduit brokerage encompasses two intertwined processes. The first process, algorithmic social alertness, relies on bot activity to curate and reconfigure information. Algorithmic social alertness is significant because it involves action triggers that dictate the kinds of information being searched, discovered, and retrieved by bots. The second process, algorithmic social transmission, relies on bot activity to embellish and distribute the information curated. Algorithmic social transmission is important because it can broaden the reach of information disseminated by bo...

Peer-oriented online interactions have critical implications for an individual’s virtual presence and self-cognition. Yet existing conceptualizations of internet privacy concerns have solely focused on the control of personal information release and on online interactions with online vendors. Drawing on the theory of personal boundaries, this study revisits the theoretical foundation of online privacy and proposes a multidimensional peer-related privacy concern construct, that focuses on privacy violations from online peers. We term this new construct “Peer Privacy Concern” (PrPC) and define it as the general feeling of being unable to maintain functional personal boundaries in online activities as a result of the behavior of online peers. This construct consists of ...

We screened articles based on their abstracts and keywords in their text, reviewed potentially relevant articles, and screened their references to (a) assess whether the article met inclusion criteria and (b) identify additional articles. Chatbots, their use cases, and chatbot design characteristics were extracted from the articles and information from other sources and by accessing those chatbots that were publicly accessible.ResultsOur search returned 3334 articles, 61 articles met our inclusion criteria, and 61 chatbots deployed in 30 countries were identified. We categorized chatbots based on their public health response use case(s) and design. Six categories of public health response use cases emerged comprising...

Drawing on the theory of psychological boundaries and previous literature on information privacy, we extend the extant conceptualization of information privacy by developing a multidimensional privacy construct contextualized to online social networking platforms. We term this new construct online social networking privacy (OSNP). The new construct: (1) contextualizes extant information privacy dimensions to a social networking context; (2) adds dimensions that tap into privacy control over virtual interactions and over psychological independence, both of which become salient when social interactions (rather than transactions) are the focus of online activities; and (3) includes privacy concerns with respect to two types of stakeholders (social platform providers and online peers), recognizing online social networks as platforms fo...

We examine the effects of such technology-mediated work-related interruptions that occur during one’s time off on both work and nonwork outcomes. Leveraging theoretical perspectives from interruption, work–life interface, and conservation of resources, we conceptualize both positive and negative effects of such interruptions on behavioral and psychological outcomes. We identify three mediating mechanisms via which these effects occur: interruption overload and psychological transition via which negative effects occur and task closure via which positive effects occur. Results reveal significant effects of interruptions on work and nonwork outcomes through the three mediating mechanisms. Although positive effects are observed, the total eff...

Yet consumer tolerance for uncertainty differs across cultures, requiring e-vendors to decide whether to adapt websites to different cultures when operating globally. We examine the effect of Hofstede’s cultural dimension of uncertainty avoidance (UA) on consumer perceptions of e-loyalty. Viewing information quality, trust, and system quality as uncertainty reduction mechanisms, UA is hypothesized to moderate relationships involving these constructs in a recognized model of IS success. Specifically, we posit that relationships involving these constructs will be stronger for consumers from high UA cultures. Using data drawn from over 3,500 actual consumers from 38 different countries, and controlling for the impact of other cultural dimensions, results suggest that UA moderates the effects of information quality on perceived usefulness, and of trust on e-loyalty, but not system quality relationships. W...

Yet these systems persist and decision makers continue to allocate them resources despite better alternatives. Our research focuses on why such declining systems are not retired or replaced despite evidence that they have outlived their utility. IS research has studied such escalation of commitment but in the context of failing Information Systems Development (ISD) projects. While on the surface declining systems and failing ISD projects seem similar, important contextual differences imply that extant theorizing for failing projects is insufficient to understand the factors influencing persistence with declining systems. Our research contextualizes and extends escalation of commitment research to (a) understand factors influencing persistence with declining systems, and (b) extend the boundaries of current theory beyond the ISD context by redefining antecedents and hypothesizi...
