Managing and modeling the price reduction effect in mobile telecommunications traffic

As needs for telecommunications services diversify, an increasingly wide range of services is becoming available in the market. Service price reduction is one strategy used by service providers to retain existing subscribers. A price reduction for one service, however, can affect the individual-level usage for other services. Price reductions can also be imposed on a service provider by regulation. For these reasons, understanding how price reductions affect service usage is of growing importance to the telecommunications industry for purposes of pricing and tariff development. In this paper, an individual-level usage model for telecommunications services is developed and the effects on usage of a price reduction are analyzed. The model is applied to age-stratified aggregate traffic data for a Korean mobile telecommunication service provider. Finally, a 0-1 integer programming model is proposed for choosing which market segment should be targeted with a price reduction to minimize revenue loss. These models can be applied to market segmentation and price reduction strategy.     

我国电子商务环境下的移动支付问题研究

移动支付是在交易活动中以手机作为支付手段,即将手机与信用卡号码链接起来通过手机代替信用卡来支付交易费用,它具有方便、安全、成本低廉等优势,但目前的消费观念、技术支持、利益分配、手续繁杂等多种因素制约了移动支付的快速发展。我国移动支付在现有技术条件下主要有虚拟支付和移动现场支付两种基本模式。移动支付提供商应着力于创新商业模式,实现产业共赢;正确定位,积极开发市场;强化技术支撑,确保交易安全;加强行业协同,规避政策风险;利用新技术,抢占新市场。     

Two Principles of Broadcast Media Ownership for a Democratic Society

Technological advances in media communications have raised questions about the appropriateness of media ownership rules for traditional TV and radio broadcast. This article contributes to this debate by defending a set of principles that ought to govern the distribution of broadcast spectrum. In particular, it defends principles reflecting the ‹public interest’ constraint currently informing broadcast media ownership rules, and argues against a free-market procedure for distributing spectrum use. The argument relies upon the application of a political constructivist approach typical to many political theories. In applying this approach, the author illustrates the strengths and weakness of constructivism and in the process provide an example for how constructivism can be applied to other subjects. As a result, the article has two aims. First, it defends a set of broadcast ownership principles. Second, it provides a model for how philosophers might apply constructivism to other subjects.

Unlocking the promise of mobile value-added services by applying new collaborative business models

Due to the intense voice service competition and subscriber growth saturation, the average revenue per user (ARPU) of mobile communications service providers continues to decline, thereby severely affecting their total revenue and profitability. To counter this challenge, mobile communications service providers are now moving from “tariff competition” to “service competition.” As mobile communications enter the next-generation network (NGN) era, network bandwidth and transmission speed are greatly enhanced. The enhancement enables mobile communications service providers to provide content-rich, multimedia value-added services to create new service value, meet demands of customers, and increase ARPU. To understand how to construct mobile value-added services, this study uses survey forms to collect feedback from 35 industry and research institution experts and scholars and to present systematically the finding on the mobile value-added services strategy. The research employs the analytic network process (ANP) to analyze the strategy of mobile service providers in delivering mobile services in the NGN. The business strategy evaluation framework and evaluation result can be used as guides for players in the mobile communications industry to review, improve, and enhance their service and strategy.

The role of mobile handsets in advanced network service evolution: Evidence from Japan

This paper aims at a better understanding of the mechanisms of mobile network service evolution through a closer examination of the context of mobile handsets. It aims first to establish quantitatively that mobile handsets are a determinant of mobile network service evolution patterns, and second, to develop a consistent perspective capable of explaining the evolution of various mobile network services. Despite the fact that mobile handsets are indispensable to users of mobile network services, surprisingly little is known about the role of these handsets in mobile network service evolution. This paper provides quantitative evidence of a positive relationship between intra-network-carrier penetration rates for mobile network service subscribers and mobile handsets designed for these services. The relationship is such that if one network service is diffused more than another, the mobile handsets related to the more diffused service are similarly more widely diffused in the market, and vice versa. The evidence is derived from an analysis of two mobile network services in Japan, mobile Internet and third generation mobile, initiated by NTT DoCoMo and KDDI. There are no existing studies that consistently explain the mechanisms of different mobile network service evolution patterns. Since the positive relationship that emerges from the analysis is consistent for both cases, by examining the mechanisms underlying this relationship, the paper develops an adequate and consistent perspective based on a constituent model reflecting the technological and competition structure of mobile network services. From this perspective, this positive relationship can be explained as the similarity or dissimilarity in essential technology ownership distribution across constituents. This perspective describes mobile network evolution in terms of changes in the distribution of essential technology ownership and, therefore, could be generalised more widely.     

MVNO services: Policy implications for promoting MVNO diffusion

This study seeks to validate a comprehensive model of consumer acceptance in the context of MVNOs. While the MVNO business model has gained much popularity over the past few years, it shows a sign of drastic decrease. This study uses the unified theory of acceptance and the use of technology (UTAUT) model with constructs from the innovation diffusion theory (IDT) such as compatibility, relative advantage and social influence. Structural equation modeling is used to construct a predictive model of attitudes toward the MVNO services. While the model confirms the classical role of technology adoption factors (i.e., perceived usefulness and ease of use are key antecedents to consumers’ intention), the results also show that users’ intention and usage are influenced by IDT factors. The model brings together extant research on MVNO and provides an important cluster of antecedents to eventual technology acceptance via constructs of behavioral intention to use and to the actual MVNO usage. Policy implications of MVNO are discussed in terms of consumer adoption and market diffusion.     

Network effects and the adoption of new technology: evidence from the U.S. telecommunications industry

This paper examines variations in the adoption of new technology by firms operating in a network-based industry: telecommunications. These variations are explained as a function of three network effects: the first is the conversion effect, driven by operations-related increasing returns to scale; the second is the consumption effect, driven by demand-side increasing returns to scale; the third is an imitative effect. We expect the conversion effect to be felt more strongly during earlier phases of a technology's evolution, while a strong consumption effect is felt throughout. The imitative effect is also expected to be felt throughout. These hypotheses are examined with respect to electronic switching adoption in the local operating sector of the U.S. telecommunications industry. An analysis of the variations in adoption levels of the 40 largest firms over a period lasting from 1973 to 1987 supports our expectations, except for the imitative effect. © 1998 John Wiley & Sons, Ltd.
