The late take-off phenomenon in the diffusion of telecommunication services: network effect and the critical mass

Telecommunication services are distinctive in that their adoptions are influenced by network effect resulting in the late take-off phenomenon and the critical mass problem. In this paper we examined the late take-off phenomenon in the diffusion process of telecommunication services. We first compared the parameters of the diffusion process of consumer durables with those of fax services in the US and Korea. By analyzing the parameters of a new diffusion model based on the threshold model proposed by Markus, we found that the late take-off phenomenon resulted from the low heterogeneity of the threshold distribution for the potential adopters. A simulation approach was proposed for the theoretical implication of the critical mass problem in the start-up telecommunications services.

Stochastic generalizations of demand systems with an application to telecommunications

Systems of demand equations are considered for at least two reasons. First, they offer a theoretical completeness, and second, they embody a number of restrictions which lead to a more parsimonious specification concerning the number of parameters. As it turns out, the quantity and quality of the data are often such that the demand systems considered are not restrictive enough in the sense that large numbers of parameters still remain which cannot be estimated with ‘great precision’. Paradoxically, the restrictions that are considered are often rejected by the data.In this paper we propose a system of random coefficient telecommunications demand equations in a panel data framework. These equations correspond to alternative ways (which have different costs) of placing a call. The system is formulated in such a way that it incorporates the homogeneity condition, as well as stochastic versions of the symmetry and weak separability restrictions. The stochastic versions are given in terms of moments and so they do not have to hold in each individual case. Under certain conditions they reduce to their deterministic counterparts. Finally, we empirically implement the model and compare the results to what they would be in a corresponding deterministic framework.     

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.

Political economy of telecommunication infrastructure: An investigation of the National Broadband Network early rollout and pork barrel politics in Australia

It has been argued that infrastructure unevenness rigidifies into more lasting structures of socio-economic and political privilege and advantage. This paper focuses on telecommunication infrastructure as the backbone of the fast-growing digital economy, and raises important questions about the early National Broadband Network (NBN) rollout in Australia. The paper asks whether there was any case of pork barrelling in the selection of early release sites that enjoyed a regional competitive advantage against other localities that had to wait several years to receive the infrastructure. The answer to this question then leads to a second question about the degree to which voting in the early NBN release sites has swung following the infrastructure rollout. In order to answer these questions the paper examines the voting patterns in the earlier NBN release sites versus all electorates in the Federal elections in 2007–2013 using the data available via Australian Electoral Commission. Findings show trends of politically targeted funding, followed by vote swing in the very next election.     

Powering economic growth and development in Africa: telecommunication operations

This study investigates the effect of telecommunication operations on economic growth and development in selected African countries. The analysis considers a panel of 46 African countries from 2000 to 2015. To measure economic growth, real gross domestic product serves as the proxy, while economic development is measured by the Human Development Index, and telecommunication operations by a composite index of telecommunication computed from mobile line, fixed/CDM line and Internet access penetration via principal component analysis. The physical capital stock is measured by gross fixed capital formation, level of employment by the employment to population ratio, human capital development by enrolment in secondary education for both sexes and technology transfer by net inflows of foreign direct investment in Africa. The empirical results suggest that telecommunication operations promote economic growth and development in Africa. These results imply that for every positive expansion in telecommunication operations and physical capital stock, aggregate output and standard of living will adjust positively in Africa. Thus, an appropriate policy to improve overall investment in Africa and most especially in the telecommunication sector since the spillover effect cut across other sectors and the general economic performance.

Factors influencing the user acceptance of digital home services

Digital home services provide multimedia entertainment, communication, and healthcare services to the public in order to make their lives more convenient. Many articles predict that the digital home service market will be huge and that many will take advantage of this situation. The purpose of this paper is to identify the future market for digital home services in South Korea by exploring the existing critical information and literature. This study proposes a conceptual model for assessing the adoption of digital home services, for which survey data from 600 heads of households in Korea were collected and used to test the proposed model. This paper also examines customer characteristics and their relationship with the acceptance of digital home services. First, the findings indicate that infra-service is mainly determined by age, region, job, family type, house type, and attitude towards adoption of new products. Second, home entertainment service is also significantly affected by gender, age, region, family type, family member, house type, and attitude towards adoption of new products. Third, home healthcare service was positively affected by gender, region, job, and usage period of high-speed internet. This study may provide companies with valuable guidelines for the implementation of digital home services.
