The impact of regulating mobile termination rates and MNO-MVNO relationships on retail prices

A mobile virtual network operator (MVNO) provides mobile telecommunication services by eluding the constraints of the radio communication infrastructure and establishing an agreement with a hosting network operator (HNO) for the use of its spectrum. Thus, MVNOs offer a wide range of mobile services and directly compete with every mobile network operator (MNO). This paper studies the economic justifications for potential regulatory intervention that defines the level of mobile termination rates (MTRs) and negotiations and agreements among MVNOs and HNOs. The results show that symmetric MTR reduction leads to competition growth among operators, forcing every operator to reduce retail prices and, consequently, to enhancing consumer welfare. The paper also finds that a collaborative strategy adopted by an HNO and an MVNO is advantageous for both and induces a reduction in retail prices, thus weakening other MNOs.     

Change and continuity in Japanese corporate governance

Previous studies on Japanese corporate governance were largely based on the agency theory framework, and can be seen as attempts to understand the unique monitoring mechanisms in the Japanese context. This paper briefly reviews prior research and then discusses the recent changes in the environment that have been affecting Japanese corporate governance. Our central argument is that there is both change and continuity in Japanese Corporate Governance. We also present emerging research from an institutional theory perspective. In this line of research, corporate governance is treated as part of a nation’s institutional framework and hence, researchers need to understand unique institutional arrangements that affect corporate governance practices and their change or continuity.

Internationalisation in the telecommunications services industry: Literature review and research agenda

A review of 356 publications addressing internationalisation aspects of the telecommunications services industry (TSI) shows a growing body of contributions, mainly covering research themes like settlement and regulation policy, strategic alliances and incumbents’ reactions to deregulation as well as opening of markets in-depth until recently. Wireline telephony TSI has been the dominant segment in most contributions, while the mobile or broadband Internet segments only featured in more recent work. Segment characteristics like non-uniform barriers to entry, different reasons for alliances and non-uniform levels of internationalisation differentiate these TSI segments pose a number of additional questions concerning telecom firms’ internationalisation strategy and success promising for future research.     

Supply chain environmental investments in dynamic industries: Comparing investment and performance differences with static industries

Research linking investments in environmental practices to firm performance has matured over the past years. However, empirical research is still ambiguous on how and whether investments in environmental practices improve a plant's performance. We believe that contingency factors, especially the industry in which plants act has a significant role in the success of environmental investments. Using empirical data collected across a wide range of industries our results indicate that plants competing in dynamic industries such as apparel do on average invest less in supply chain environmental practices compared to plants in static industries. In addition, these environmental investments do not significantly improve operational performance in dynamic industries in terms of cost, quality, delivery and flexibility. However, in static industries environmental investments do significantly improve a plant's operational performance in terms of cost, quality and flexibility.     

The competition among mobile network operators in the telecommunication supply chain

In the mobile telecommunication sector, the high competitiveness has increased the complexity of strategic interactions among operators. As the vertical integration has become anything but a choice and not a compelling technical solution, the contest takes place at different levels of the components of the operator value chain: the network infrastructure, the service development and supply, and the relationship with consumers.Mobile virtual network operators act as retailers and concentrate on the last segment of the value chain by establishing commercial agreements with hosting network operators, which act as manufacturers, to get access to radio communications infrastructure. Productive processes of mobile services offered by operators are different and this difference is imperceptible to customers. Processes difference mainly consists in the infrastructural diversity of the operators and implies different consequences on each network service element.A model has been defined to analyze the consequences of such diversity in the competition among HNOs, MNOs, and MVNOs by focusing the attention on the characteristics of the call path, in dependence of the types of operators. In fact, many variables interact to define the call path, such as marginal costs and revenues, infrastructural investments, and interconnection charges among operators. The analysis of the results, obtained by the model, gives information on variations of retail prices, market shares, and profit allotment, to adopt the proper strategies. In particular, the model results shed light on how certain MVNOs should enter the markets and adopt a collaborative strategy with HNOs. The model owns the capability of being applied to different contexts, thus representing for the regulator a potential instrument of relevant usefulness.     

Institutional life of intuitive insights: Legitimacy of virtuoso intuitive marketing management

Intuitive insights have been recognized as an integral part of marketing and managerial proficiency. In this article, we expand upon this understanding by theorizing the institutional dimension of intuitive expertise. By developing a theoretical framework with supportive propositions we maintain that for intuitive managerial expertise to be effective it requires legitimization in its inter-organizational contexts. Intuitive insights hence have a significant institutional and social existence, irreducible to cognition. This means that institutional logic may support or contradict efficient cognitive strategies, significantly influencing the performance of marketing management. Managerial implications follow to the fields of marketing management and intuitive decision-making.     

Why is South Korea at the forefront of 5G? Insights from technology systems theory

South Korea became the first country in the world to launch a nationwide 5G network and commercialize 5G services. The Korean government played an essential role in the development of 5G, creating a tailored institutional arrangement that allowed South Korea to be at the forefront of 5G. In particular, the government set up a detailed time plan on how to go about 5G deployment and commercialization. The government also facilitated collaborative work between companies, research institutes, and academia, and strongly promoted R&D work for the development of 5G equipment, devices, and applications, providing financial and administrative support, opportunities for field trials, and various forms of incentive, including tax benefits to companies. This study analyzed the 5G socio-technical system in South Korea through the lens of technology systems theory, identifying and discussing crucial factors that have propelled 5G development and major latent aspects, such as the lack of killer applications for consumers and in vertical industries, which may potentially hinder the further growth and stabilization of the 5G system in South Korea.     

Zero-rating arrangements of mobile Internet access service providers – An analysis of main factors shaping the need for regulatory interventions

Zero-rating is the practice of providers of radio-based Internet access for moving telecommunication devices of excluding traffic generated by specific online applications from usage counted towards capped allowances or strictly metered tariffs of their end customers. Worldwide and particularly in the European Union (EU), current regulatory frameworks for zero-rating arrangements (ZRA) imply that regulators have to examine on a case-by-case basis whether they prohibit a concrete ZRA or impose restrictions. Such conditions are set because regulators believe that a ZRA runs counter to the interests of end customers or application providers or impedes effective competition between application and Internet service providers. Thus, it is necessary to clarify which case features ought to be inspected in such zero-rating assessments and which feature levels speak against or in favor of regulatory measures linked to ZRA. The present article identifies nine design features of ZRA, three characteristics of customer groups targeted by such offers and three background characteristics of the markets for Internet access services and applications which are of special importance in decisions concerning the need to regulate (to abstain from regulating) zero-rating practices of mobile network operators. The analysis shows that in many instances interests of end customers, application providers as well as of politicians seeking to promote the competitive dynamics on mobile Internet access service and application markets are best served if regulatory authorities tolerate ZRA and control for potential harmful effects after their market launch. Moreover, the study reveals that empirical research on customer reactions to ZRA is urgently required.     

The effects of GSCM drivers and institutional pressures on GSCM practices in Taiwan’s textile and apparel industry

This empirical study of Taiwan’s textile and apparel manufacturers investigates the relationships between green supply chain management (GSCM) drivers (organizational support, social capital and government involvement) and GSCM practices (green purchasing, cooperation with customers, eco-design and investment recovery). It also studies moderating effects by institutional market, regulatory and competitive pressures. Through hierarchical moderated regression analysis, the results of this research show that (1) except for investment recovery, the other three GSCM practices are positively affected by GSCM drivers; (2) investment recovery is positively affected only by organizational support; (3) market pressure has no moderating effects on most of the relationships between GSCM drivers and GSCM practices; (4) regulatory pressure has positive moderating effects on most of the relationships between GSCM drivers and GSCM practices; and (5) competitive pressure has negative moderating effects on most of the relationships between GSCM drivers and GSCM practices. Finally, the implications of this study and future research are discussed.
