The constitution of ‘third workspaces’ in between the home and the corporate office

This study analyses the constitution of commercially provided work spaces situated in between the home and the corporate office. These new workspaces are enabled by digital network technologies. Theoretically, this new category of contemporary business spaces is conceptualised as ‘third workspaces’, with reference to the work of Oldenburg (1989), Soja (1996) and Lefebvre (1991 [1974]). Empirically, these workspaces are explored in two ethnographic case studies dealing with recently founded and successful third workspace providers. The grounded theory resulting from these case studies addresses the role of the material settings, the technologies, the work ideologies as well as the user practices. Overall this study offers an analytical framework for studying and managing third workspaces, and highlights the ambiguities in the constitution of third workspaces between the design and management on the one hand and the user practices on the other.     

Network-centric digital development in Korea: Origins,growth and prospects

South Korea is currently the world leader in digital network infrastructure and the leading example of ICT-driven development. However, the explanation of how and why Korea accomplished these things is not clearly apparent from a review of mainstream scholarship. A deeper understanding of Korea’s “miracle on the Han” requires more historical, cultural, political and social context. This study addresses questions of how, when and why a nation whose infrastructures were utterly destroyed at the 1953 cessation of hostilities in the Korean War could emerge as the world’s digital network leader. It examines policy issues bearing on digitization of networks, network architecture and network technologies, along with broader context in which these policies were considered, drafted and implemented. Chronologically, the study explains the origins of digital development in the revolutionary decade of the 1980s, Korea’s rise to world broadband leader in the 1990s and its ambitious plans for next generation networks. The study concludes with a review of policy “lessons”, including both successes and failures, that may be drawn from the Korean experience.

The impact of digital technology on relationships in a business network

This paper examines the impact of digitalization - the adoption of Internet-connected digital technologies and applications by companies - on B2B exchanges. While B2C exchanges are the subject of numerous studies on the transformations brought by the digital technologies, B2B exchanges are far less analyzed. Building on a conceptualization of exchanges between companies as made of activity links, resource ties, and actor bonds, this paper offers to identify three types of “digitalization” according to the nature of the most deeply impacted link. Five cases of digitization in different industrial sectors and five companies providing digital solutions for businesses illustrate these three types. This typology provides an alternative to analyses based on the nature of digital systems used by B2B companies.     

Internet of things technologies,digital servitization and business model innovation in BtoB manufacturing firms

Technologies like the Internet of Things (IoT) are offering new opportunities and posing serious challenges to firms, forcing them to create entirely new business models, migrating from the conventional product-centric approaches to (digitally-based) service-oriented ones. This paper – following a qualitative research method – aims at describing the service-oriented impact of IoT technologies on firms' business models, with a particular focus on opportunities and challenges for BtoB manufacturing firms.Being the impact of IoT technologies on businesses a quite recent research stream, to date scarce attention has been devoted to the topic with specific attention to its impact on service-oriented business models in manufacturing firms. The paper contributes in this research stream in different ways. It proposes a map of digital servitization that helps in understanding firms' strategic transitions caused by technologies, making both theoretical and managerial contributions. Firstly, the research underlines the impact of the firms' sales model as a strategic factor in shaping firms' digital servitization strategies. In addition, three progressive levels of digital servitization complexity are identified, namely product- process- and outcome-oriented, that are based on an increasing use of IOT technologies and have specific challenges and opportunities.

SPLINTERING AND INERTIA IN NETWORK INDUSTRIES*

We analyse a stylised game of technology adoption with network effects and two new technologies. Potential adopters can adopt early, late or not at all. We show that one of the reasons for the failure of new technologies can be the presence of multiple incompatible variants of that technology. An adopter's individual incentives to adopt are lower with two technologies than with one. Turning to aggregate expected welfare, we find that two active technologies may be welfare‐improving.
