“Perceptions of Control Legitimacy in the Gig Economy: The Case of Uber Drivers”
Martin Wiener is an Associate Professor in the Information and Process Management Department at Bentley University (Waltham/Boston, MA, USA), as well as an Affiliated Researcher at the Stockholm School of Economics Institute for Research (Sweden) and the Friedrich-Alexander University Erlangen-Nürnberg (Germany). His research concerns the control of IS projects, technology-mediated control, and data-driven business models, and has been published or is forthcoming in outlets including Information Systems Research, Journal of Management Information Systems, and MIS Quarterly. He currently serves as Associate Editor for Information Systems Journal, as well as on the Editorial Review Board of Journal of the Association for Information Systems and Information & Management.
The rise of the gig economy has become a global phenomenon that encompasses various industries. Instead of hiring full-time employees, gig economy companies ‘outsource’ work via online platforms to freelance workers who are paid for completing a given task (‘gig’). While gig workers are often portrayed as independent contractors, several gig firms such as Uber leverage advanced digital technologies and smart algorithms to exercise tight control over their freelance workforce. This independence-control paradox raises interesting questions regarding gig workers’ perceptions of control legitimacy. Therefore, in this study, we build on the IS control and related literatures to derive a three-dimensional conceptualization of control legitimacy perceptions attuned to the gig economy (perceived autonomy, perceived justice, and perceived privacy invasion). On this basis, we present a research model with supporting hypotheses, focusing on the antecedents and effects of different control legitimacy dimensions. Our model is tested using a dataset of 621 Uber (and Lyft) drivers from the United States.

“Collaborative Innovation in Information Technology Outsourcing”
May 22, 2017
Johann Kranz is professor of Internet Business and Internet Services at the LMU Munich. He holds a Master’s degree in Business Information Systems from the University of Leipzig and Master’s degree in Business Research from the LMU Munich. His dissertation on Smart Grids at the Munich School of Management, LMU Munich, was awarded with the dissertation award of the Alcatel-Lucent Foundation for Communications Research. He was a visiting scholar at Columbia University (New York City, USA), Syracuse University (New York, USA), Waseda University (Tokyo, Japan). His primary research interests include Green Information Systems, IT-service innovations, Strategic IT Management, and E-Commerce. His research has been published in major journals including Information Systems Journal, Journal of Service Research, Business & Information Systems Engineering, Energy Policy, and Electronic Markets.
Collaborative innovation, in which client and vendor seek to jointly develop strategic innovation, is an emergent phenomenon in information technology outsourcing. As innovation processes and outcomes are dynamic, collaborative innovation relationships require a governance mode that not only promotes collaboration but also safeguards against the exchange hazards arising from task complexity, task interdependence, and environmental dynamism. This study builds upon relational contract theory and social embeddedness theory to examine how strategic innovation can be fostered in the context of information technology outsourcing. The proposed model is validated using survey data from 260 senior-level IT employees. Results indicate that relational factors are more central to relationship learning, whereas vendor’s contribution to strategic innovation depends chiefly on incentives and flexibility provided by relational contracts.

“Utilizing, Producing, and Contributing Design Knowledge in DSR Projects...and Asking the Right Questions for it”
October 29, 2018
Andreas Drechsler is a Senior Lecturer of Information Systems at Victoria University of Wellington, New Zealand. He holds a doctorate degree in Information Systems from the University of Duisburg-Essen, Germany and has also been a Visiting Scholar at the University of South Florida in the United States. His research interests comprise IS/IT management, IT project management, and design science research.
In the past, design science research (DSR) has often been criticized to struggle with making contributions beyond the developed artefact itself. This presentation distinguishes several design knowledge types in IS research and examines six different modes of utilizing and contributing design knowledge in the DSR project context. We call these modes design theorizing modes. Each mode draws on different knowledge types in a different way to inform the production of project design knowledge (including artefact design) in a DSR project or to grow the human knowledge bases in return. As different knowledge contributions require the corresponding formulation of suitable research questions, the presentation also distinguishes different types and formats of research questions for each design theorizing mode. Design science researchers can draw on our design theorizing modes and design knowledge perspectives to utilize the different extant knowledge types more consciously and explicitly to inform their build and evaluation activities. Researchers can further use the modes and perspectives as well as the provided research question templates to better identify and explicate their research’s contribution potential to the human knowledge bases.

“Disentangling the Impact of Multichannel Services on Consumer Evaluations and Decisions in Integrated Sales Channels”
June 20th, 2016
Manuel Trenz is assistant professor of the Chair for Information Systems and Management at the University of Augsburg. He is also appointed as a research associate at the research department for "Information and Communication Technologies" (ICT) of the Centre for European Economic Research (ZEW). He holds a Ph.D. from the Business School of the University of Mannheim, Germany, where he was a scholar in the Operations and Information Systems program of the Graduate School of Economic and Social Sciences. During his PhD, he spent four months at the Marshall School of Business, University of Southern California. His research focuses on the convergence of digital and physical sales channels and the implications of innovative IT services on user perceptions and behavior.
With digitalization blurring the boundaries between physical and virtual environments, most ‘brick-and-mortar’ retailers have turned to online channels as a means of expanding their businesses. Increasingly, these multichannel retailers have come under immense pressure from pure online retailers because their physical infrastructure has eroded their ability to compete price-wise. Although the aforementioned physical infrastructure could also present opportunities for multichannel retailers to differentiate themselves by offering integrated multichannel services, the appeal of such services has not been fully comprehended by either researchers or practitioners. To this end, this paper endeavors to account for the impact of different multichannel integration services on consumers’ channel preferences. In contrast to the common assumption that online offerings are being evaluated based on the characteristics of the website and other online information, the explosive growth in multichannel retailers and the emergency of channel-spanning service offerings requires an extended perspective on the evaluation of online services. Bridging the gap between diagnostic and prescriptive studies on multichannel commerce, we explore the competitive advantage of multichannel integration services. An experimental study sheds light on the intricate relationships between the perceptions of multichannel integration services for acquisition and recovery and their outcomes. Results indicate that the appeal of integrated multichannel offerings differs from that of prior research on pure online and pure offline channel options. Accordingly, channel convergence requires research to adapt to technological advancements and embrace a more complex view when investigating multichannel commerce.

“Exploring New Online Recommendation Spaces Through Serendipity”
May 23, 2016
Christian Matt is Assistant Professor at the Institute for Information Systems and New Media at LMU Munich. He holds a Ph.D. in Management from LMU and master’s degrees in Computer Science (University of Colorado at Boulder) and in Management (LMU Munich/EM Lyon). He was a visiting scholar at the Wharton School of the University of Pennsylvania, Singapore Management University, and EM Lyon. His current research focuses on digitization, both from corporate and individual perspectives. Other research interests include e-commerce and recommender systems, as well as privacy. His research has appeared in Journal of Management Information Systems, Electronic Markets, Business and Information Systems Engineering, MISQ Executive, among others.
Recommender systems are often criticized for keeping users in a “filter bubble” by recommending products that are very close to users’ preferences – yet filter out products that may pleasantly surprise users. We hold that the concept of recommendation serendipity can help users explore new recommendation spaces without sacrificing recommendation quality. Based on a controlled field experiment with 365 subjects using an online music website, our findings show that compared to the previous concept of recommendation novelty, recommendation serendipity has strongly opposing effects on users: while recommendation serendipity has positive effects on both users’ cognitive and affective reactions, recommendation novelty alone is counterproductive and elicits negative cognitive and affective reactions. We also find that preference fit and perceived enjoyment mediate the relationship of novelty/serendipity and the intention to use the recommender and to purchase the recommended products.
Dr. Sven Laumer, University of Bamberg
“From Adoption to Reuse: Technology Adoption Studies along the IT Life Cycle”
November 16, 2015
Sven Laumer is post-doctoral researcher (Akademischer Rat) at the University of Bamberg. He is interested in user acceptance, user resistance, and technostress in general and the support of information systems for HR tasks, virtual teams, the IT workforce, computer-supported cooperative work, and process-oriented enterprise content management in particular. His research is based on several projects with industry partners and has been published among others in European Journal of Information Systems, Information Systems Journal, Journal of Strategic Information Systems, and Journal of Information Technology. He is the winner of the ACM SIGMIS Magid Igbaria Outstanding Conference Paper of the Year 2011 Award and two best reviewer awards.
In his talk, Sven Laumer will discuss technology adoption studies along the IT life cycle. He will illustrate research opportunities to better explain IT use in general. In specific, he will talk about a study that introduces reuse as an additional use pattern in the IT life cycle of voluntary use of business-to-consumer (B2C) technology. Drawing on practical observations that some consumers stop using an IT and then go back to using it after a given period of time two different antecedents of re-use will be introduced: non-use beliefs and use beliefs. The presented study reveals that the strength of past habitual patterns moderates the degree to which use or non-use beliefs impact re-use behavior. The theoretical arguments are tested using an experiment and developed in a mixed-method study including qualitative and quantitative data.
