Abstract Taxonomies are classification systems that help researchers conceptualize phenomena based on their dimensions and characteristics. To address the problem of ‘ad-hoc’ taxonomy building, Nickerson et al. (2013) proposed a rigorous development method for information researchers. Eight years on, however, status quo research shows application this lacks consistency transparency further guidance evaluation is needed. fill these gaps, study (1) advances existing methodological (2) extends...
As online reviews play a decisive role in consumers' purchase decisions, e-commerce platforms are using review systems strategically to obtain competitive advantage. However, the strategic potential can only be leveraged if system is designed appropriately. Research on design of and effects choices has not yet been summarized or synthesized article. We aim close this gap by providing scoping review. In our synthesis we posit that moderates impact economic outcomes factors drive formation...
Purpose The purpose of this paper is to identify strategic options and challenges that arise when an industrial firm moves from providing smart service toward a platform. Design/methodology/approach This conceptual study takes on multidisciplinary research perspective integrates concepts, theories insights management marketing, information systems platform economics. Findings outlines three types – data platform, product matching as for firms wish evolve providers providers. Research...
Consumer ratings play a decisive role in purchases by online shoppers. Although the effects of average and number consumer on future product pricing demand have been studied with some conclusive results, variance these are less well understood. We develop model where we decompose into two sources: taste differences about search experience attributes durable good, quality among instances this good form failure. find that (i) optimal price increases decreases caused differences, (ii) decrease...
Abstract The digital economy has brought about multi-sided platforms as superior configurations for value co-creation. However, the academic discourse on is scattered across disciplines—including management, information systems, and economics. Based a systematic literature review of 140 papers from nine disciplines, we inductively develop framework that provides conceptual point reference conducting boundary-spanning research platforms. Systematizing identified concepts, introduce three...
Taxonomies are design science artifacts used by researchers and practitioners to describe classify existing or future objects of a domain. As such, they constitute necessary foundation for theory building. Yet despite the great interest in taxonomies, there is virtually no guidance on how rigorously evaluate them. Based literature review sample 446 articles, this study explores criteria currently employed taxonomy evaluations. Surprisingly, we find that only minority building projects...
Modeling languages for business models are a powerful and flexible means of representing communicating knowledge related to models. More than fifteen years after Osterwalder et al. (2005) clarified the ontology model concept in this journal, we offer systematic cross-disciplinary assessment literature on modeling (BMMLs) that facilitates visualization concept. In so doing, synthesize organize dispersed across different disciplines which BMMLs have originated highlight potential weaknesses...
We investigate the impact of delegating decision making to information technology (IT) on an important human bias—the sunk cost effect. To address our research question, we use a unique data set containing actual market transaction for approximately 7,000 pay-per-bid auctions. In contrast with laboratory experiments previous related studies, presents advantage investigating effects IT-enabled automated bidding agents occurrence bias in real transactions. identify normatively irrational...
Drawing on construal level theory, prior literature has found a positivity bias in online ratings when consumers evaluate an experience from psychological distance, whether spatial or temporal. Self-distancing theory posits that distance enables individuals to reflect psychologically distant negative experiences more genuinely, less biased way. This raises the question of due persists for experiences. To address this question, we collected data large review platform identification reviewers’...
Business models are not typically doomed to remain as they are, rather, may contain a variety of options be changed or extended. Nevertheless, current approaches for business model representation cannot handle such options, because no appropriate modeling constructs available. This substantially inhibits the qualitative consideration in design. Also, it integration into subsequent quantitative analysis. Our contributions this context twofold: at 'macro-level', we combine representations with...
