Economic analysis of the introduction of the MVNO system and its major implications for optimal policy decisions in Korea

This study analyzes the anticipated economic effects arising from the introduction of the mobile virtual network operator (MVNO) system in the mobile communications service market. For the analysis, actual data (or estimated data)—such as price elasticity, the number of subscribers, traffic volume, rate, and access charge—were combined with an assumption about a competition scenario in the future market. Based on this analysis, consumer surplus, and change in the service provider's profits were estimated according to the type of policy that may be adopted for the MVNO system by the regulator. The results of the analysis indicate that consumer surplus appears to increase largely because of the reduction of the mobile service rate by the promotion of “service-based competition,” which occurs upon adoption of an MVNO policy in the mobile communication service market. Moreover, the introduction of an MVNO system into the mobile communication market seems to be socially beneficial regardless of policy type if access charges are set reasonably by a cost-plus or retail-minus method. In particular, in order to make sense of the introduction of a special MVNO, whether by the cost-plus method or the retail-minus method, the correct discount rate must be used in setting an access charge between the special MVNO and the significant market power (SMP) mobile network operator (MNO).     

Diversification strategies in network-based services: The case of mobile virtual network operators

This paper aims at discussing the entry process and competitive strategies of MVNOs in Italy and France. It illustrates the features of competition in a sector – the mobile telecom service industry – which is characterized by market saturation and demand heterogeneity. In doing so, it looks at the characteristics of the two countries in terms of competition and entry of new operators, at the motivations behind the entry of MVNOs, and at the performance of different companies. Results show that the most successful MVNOs are those characterized by the ability to find a perfect match between their core competencies (large network management, strong brand reputation) and the needs of specific segments of demand that had not been previously fulfilled. In this context, companies with ICT network management skills, whether coming from the telecom sector or from other network-based service industries such as postal operators, have been particularly successful in the market. From a policy perspective, despite the failure of some MVNOs, customers have benefited from the increased competition between MNOs and MVNOs in terms of range of service offerings and prices.     

Access regulation and infrastructure investment in the mobile telecommunications industry

While mobile virtual network operators (MVNOs) increase competition in the mobile telecommunications industry, granting market access to MVNOs may have unwanted consequences. In particular, infrastructure investment by incumbent mobile network operators (MNOs) may be smaller. This paper examines the effects of MVNO entry and access regulation on the investment behavior of MNOs. It uses firm-level data for 58 MNOs in 21 OECD countries during 2000–2008. The results suggest that mandated provision of access is related to lower investment intensity of MNOs, while voluntary access provision has no effect. Although reduced investment incentives do not necessarily correspond to under-investment, this underscores the need for those countries where MVNOs are provided access to address the issue of investment incentives.     

Cost allocation of WCDMA and wholesale pricing for mVoIP and data services

This study estimates cost-based prices for wholesale voice and data services provided to 3G (WCDMA) MVNOs according to their distinct types. For estimation, 3G MVNOs are classified into different types, and the overall cost of WCDMA facilities are separated into voice and data components based on their subscriber rates, actual traffic rates, as well as efficiency consideration of traffic rates. The study then calculates cost-based wholesale prices of voice and data services for each of the 3G MVNO types. The result of this study shows that a cost-plus pricing scheme can help achieve the policy goals of the regulator, namely, lowering telecommunications tariffs and facilitating the introduction of new convergent-type services, far more effectively than the current retail-minus pricing scheme. The findings of this study may assist firms in developing business models based on 3G networks and telecom regulators in designing policies related to interconnection, mVoIP, prepaid calls, wholesale services, and network neutrality.     

国外电信基础设施共建共享浅析

电信基础设施共建共享是为了达到节约资源、保护环境等目标,将现有的和未来新建的电信基础设施如基站、天线、网络等进行整合共享的一种运营模式。它在国外已普遍实施多年。在共建共享过程中,虽然大部分国家是市场占主导地位,但政府有效的激励和引导也是其顺利实施的有力保障。因此,政府应提供良好的发展平台,同时运营商应主动建设。     

Various wholesale price equilibria for mobile virtual network operators

In this paper, various equilibria are analyzed according to the leader–follower relationship between vertically integrated incumbents when downstream entries are present. This analysis broadens our understanding of the incentives involved in deciding the wholesale price, which can be applied to explain the different situations of diffusion of mobile virtual network operators in the telecommunications market. Several implications are derived to facilitate effective policy formulation and management.
