Global political economy of technology standardization: A case of the Korean mobile telecommunications market

This paper examines empirical cases of standardization in the Korean mobile market as vehicles for approaching the broader political and institutional context of standardization in telecommunications. A consideration of Korean standardization in the mobile telecommunications market is particularly interesting because it reveals how the state's political interests influence standards decisions, which are primarily driven by market and technological changes in telecommunications. Judged from the social construction of technology perspective which sheds light not only on technology itself but also on political, social and economic interests that surround transformations in technology, this paper highlights power relations among the major actors that have made technology standards decisions in Korea regarding second (2G) and third-generation (3G) mobile telephony. The paper also attempts to show how the Korean government has dealt with the diverse interests of various market actors while pursuing its own policy agenda.     

Competitive behavior in the European mobile telecommunications industry: Pioneers vs. followers

This paper studies the relationship between competitive strategy and improvement in the competitive position of pioneers and followers in the mobile telecommunications industry. The analysis uses a panel of data comprising all the actions of European firms operating in the digital mobile telecommunications industry with GSM 900 and/or DCS 1800 networks. The results show that competitors gain market share when they follow competitive strategies that are different from those of other firms. The paper also finds that price reduction actions represent the best approach for followers, while differentiation actions are the most effective strategy for pioneers.     

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.     

Network effects and preference heterogeneity in the case of mobile telecommunications markets

This paper demonstrates how revealed- and stated-preference analyses can be used for modeling network effects in the field of mobile telecommunications. The aim of this study was to verify if network effects may still play a role in the Polish mobile telecommunications market, measure their strength, identify their sources and variability across consumers by accounting for consumers' observable and unobservable preference heterogeneity, evaluate their monetary value to consumers, and finally, to verify if the marginal utility associated with network effects is constant. The analysis of consumers' revealed choices (currently used mobile telephone operator) allowed the identification of major differences between customer bases of incumbent and new entrant operators, and insight into the business strategies adopted in the presence of asymmetric regulation of mobile termination rates. The second part of the study—the analysis of the consumers' stated choices (made in carefully prepared and designed hypothetical choice situations, known as the choice experiments) made it possible to directly model consumers' utility functions and, in this way, investigate the nature of network effects in mobile telecommunications markets. From the results, the presence of strong network effects, which are related to the ratio of consumers' social network group using the same operator, and to the magnitude of on-net price discounts, is confirmed. These network effects can be disaggregated to pecuniary and non-pecuniary effects. Through the utilization of the random parameters multinomial logit model, consumers' observable and unobservable preference heterogeneity can be accounted for, which proved a scientifically revealing and potentially policy-relevant approach. The results might be of a particular interest to other researchers aiming at modeling consumers' preferences as well as to mobile telephone operators and regulatory authorities—it is shown that capacity for vigorous price competition between mobile operators is limited by non-price factors, which affect subscriber's choices, especially in the presence of asymmetric mobile termination rates.     

Mobile voice diffusion and service competition: A system dynamic analysis of regulatory policy

Dynamic behavior in mobile telecommunications markets is often the result of interactions between market actors. As the structure and dynamic complexity of such interactions tend to be difficult to identify, it is challenging for regulators to anticipate the effects of their policy decisions. This article uses system dynamics to evaluate the effect of technology harmonization and mobile number portability policies on mobile voice diffusion and service competition. This is realized by first modeling the endogenous feedback structure resulting in dynamic behavior in the mobile telecommunications market and then by configuring the model for retrospective simulations of the Finnish market. Based on the retrospective simulations, the effect of technology harmonization and mobile number portability policy decisions is analyzed and the usefulness of system dynamics is demonstrated.     

Quality-adjusted international price comparisons of mobile telecommunications services

Many countries' policymakers have conducted international price comparisons of mobile telecommunications services to prevent service operators from overcharging subscribers. However, those comparisons have become more complicated because of the escalation in service usage and telecommunications expenditures spurred by the proliferation of smartphones and broadband LTE wireless internet service networks. The basket-based methodologies that have been widely used for international price comparisons are also limited—first, because the baskets for comparison may not be representative of actual service usage patterns in some countries; second, because they are difficult to apply to highly differentiated service plans due to the significant increase in wireless internet service usage and widely used plans with unlimited voice call service and SMS/MMS; and third, because they cannot consider the quality of service, such as upload and download speed in various service environments, at all. As an alternative, this paper proposes a hedonic pricing model that accounts for service quality and its variation in potentially disruptive environments, as well as fixed charge for a mobile phone additional to the price of service plans. The model was used to derive quality-adjusted price indices of mobile telecommunications services for twelve cities in ten countries with broadband LTE wireless internet service. The empirical results confirmed that the price index of each city varied significantly across the specifications,—both within the United States and internationally—depending on whether the model was constructed to reflect service quality and its variation on roads, in buildings, and in subways. The price index of each city also varied depending on whether the subsidized price of a mobile phone was considered part of the monthly price of a service plan. These results have important implications for policymakers seeking to understand the ultimate level of mobile telecommunication service prices for their country in a global context.     

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.     

Entering the mobile service market via mobile platforms: Qualcomm's BREW platform and Nokia's Preminet platform

The mobile telecommunication market has evolved from simple voice to multimedia services. In the past, the primary players in mobile services were local operators in different countries; international telecommunication vendors, such as Qualcomm and Nokia, were seldom involved in the mobile service market. In order to enter this market, Qualcomm and Nokia have separately introduced their mobile application platforms, called respectively BREW and Preminet. This paper examines how the two companies attempt to share the mobile service market through their mobile platforms and internationalized business models. This paper also analyzes their mobile platforms’ business models and their strategic implications.     

Investigation of factors affecting the diffusion of mobile telephone services: An empirical analysis for Vietnam

This paper analyzes the diffusion of mobile telecommunications services in Vietnam and examines how telecommunications regulation and potential substitute/complement services affect the growth of the number of mobile telephone subscribers. Using a logistic diffusion model, it is found that fixed telephone services are a complement while data services have a negative relation to mobile telephone services in Vietnam. As for regulation, the policy of introducing competition has been found to be the most effective in influencing the adoption of mobile services. Another important result is that the estimated potential market is roughly 76% of the total population. The findings suggest that suitable regulation that guarantees competition in the mobile telecommunications market in a developing country such as Vietnam is one of the most important factors for a positive diffusion process.     

The response strategies of incumbent mobile network operators on the disruptive potential of public W-LAN in Germany

This paper examines how three incumbent mobile network operators (MNOs) in Germany responded in terms of their strategy to the emergence of the wireless local area network (W-LAN) technology and how they interpreted this potentially disruptive technology in their own strategic context. Additionally, prior empirical results and forecasts on the limited disruptive potential of W-LAN for the German MNOs lacked persuasive firm-level evidence to distinguish the real reason for the presented observations and analysis. So far it was unclear whether the observations were caused by successful response strategies of incumbent MNOs or by the inherent limited disruptive potential of the W-LAN technology. For this purpose case studies of three major MNOs in Germany were performed to assess and compare their respective response strategies. Using the theoretical framework of disruptive technology, the results were evaluated in a cross-case analysis to study how these firms interpreted and reacted to the potential disruptiveness of W-LAN. The results indicate significant differences for the respective MNOs between their perception of W-LAN as a potential disruptive technology, their strategic development processes inside the organisation to understand the potential impact of W-LAN on their respective business model, and to enforce an appropriate response strategy and structural implementation. This incumbent heterogeneity depends primarily on their idiosyncratic strategic and structural context. These findings reveal that the incumbent MNOs in Germany were aware of the disruptive technology concept but did not react in a theory-conform way. However, since W-LAN had a sustaining impact on the MNOs and their response strategies followed sustaining reaction patterns, earlier studies, which show a limited disruptive potential of W-LAN for the German MNOs, are supported.     

Behind the scenes of the telecommunications miracle: An empirical analysis of the Indian market

The paper analyzes the demand and supply characteristics of the Indian telecommunications market, with the aim of contributing to the debate on the effectiveness of universal access policies in developing countries. The discussion is supported by some empirical evidence derived from a small time-series-cross-section dataset, containing mainly information on the fixed-lines segment of the market. The analysis suggests that the price elasticity of demand for fixed lines might be sensibly higher than the levels usually found in developed countries, while the crucial role of income and other sociodemographic variables seems to be confirmed. The paper also studies the impact of cellular penetration on fixed-lines diffusion. The results suggest the existence of a (positive) network effect in low penetration areas, while substitution (displacement) seems to arise in the most developed ones. Finally, the paper analyzes the supply side of the market, to assess the impact of market competition on investment. Competition seemingly helps stimulating investment in the most developed areas, but does not seem to have a significant impact in the less developed ones.     

Estimating consumer surplus in the mobile telecommunications market: The case of Korea

This paper estimates consumer surplus in the Korean mobile telephone services (MTS) market. The Korean mobile telecommunications market has grown rapidly since 1997 when competition was introduced and Code Division Multiple Access (CDMA) technology was commercialized. Because consumer surplus is relevant to the controversy over establishing an appropriate price level between consumers and service providers, the need for a robust measurement of benefit from MTS is increasing. The measured net consumer surplus estimated by means of elasticities of demand reached about US$48.8 billion in the period 1996–2004 and the changes amounted to about US$8.8 billion during the same period. In particular, after competition was introduced into the market with an accompanying price decrease and increase in the number of subscribers, consumers have benefited greatly. Therefore, it can be inferred that a facility-based competition policy and the reduction in price of access such as handset subsidies all played a positive role in the early diffusion of MTS in Korea. The estimated consumer surplus in this paper does not include network externality (option externality); if this were considered, the total social welfare of the consumer would be larger.     

Regulation and competition in the European mobile communications industry: An examination of the implementation of mobile number portability

Over the past two decades, the mobile communications industry has seen a considerable drop in the consumer switching charges made by service providers in order to promote effective competition and ensure a level playing field for new market entrants. Mobile Number Portability (MNP) is an important regulatory measure taken to reduce switching costs, and it is believed to play an important role in fostering competition in the mobile market. MNP implementation has varied significantly across European Union countries, particularly with respect to porting time and customer fees, both of which are important factors when deciding whether to switch to another provider. The research examines the effects of MNP implementation on competition in the European mobile communications industry. The study findings indicate that subscriber churn rates are negatively affected by both the level of charges levied on subscribers wishing to maintain their current number (porting) when switching mobile providers and the length of time required to switch. The implications of the effectiveness of MNP regulation for competition in the mobile communications industry are discussed.     

Diffusion and competitive relationship of mobile telephone service in Guatemala: An empirical analysis

The purpose of this paper is to analyze the characteristics of diffusion process of mobile telephone service and the competitive relationships between mobile and fixed-line services in Guatemalan telecommunications market. We investigated the best-suited model to explain the diffusion process of mobile telephone in Guatemala by estimating diffusion curves using empirical data. Moreover, we explored affecting factors which characterize the diffusion pattern of mobile telephony in Guatemala through statistical analysis. Finally, in order to understand the effects of competition in the diffusion process of Guatemalan mobile phone service, we attempted to clarify the competitive relationship between mobile and fixed-line services using the Lotka-Volterra model. As a result, the logistic model was found to be the best model for describing the diffusion pattern. Moreover, investment in telecommunications, the subscribers of fixed-line services, and the number of operators in mobile market were found as significant determinants of mobile diffusion process. Results from the Lotka-Volterra model showed that the relationship between mobile and fixed-line services has changed from pure competition to amensalism.     

The impact of license duration on tangible investments of mobile operators

Using data from the WCIS (World Cellular Information Service) and the Telecoms Market Matrix of Analysis Mason, we were able to build a database relating the level of investment per capita to license duration for 14 countries over a 10-year period. An empirical analysis of the data shows a positive correlation between the tangible investment per capita and the license duration (the average of all active licenses or the latest license). More precisely, we observe an increase of €1.5 in the average investment per capita per year for each additional year of license duration. We also find no significant negative impact of license duration on mobile market competition. The competition outcomes are measured using the Lerner index at the operator level. Some robustness checks are performed at the country level by using the HHI (Herfindahl-Hirschman index) and the number of active mobile operators as measures of the level of competition, and we obtain additional results indicating once more that the competition is not negatively impacted by license duration.     

An assessment of the liberalization and the evolution of competition in the Moroccan mobile market

This paper analyses the liberalization process of the Moroccan mobile market since the beginning of the 21 st century. Our database ranges from 2004 to the end of 2020. First, operators’ market shares are presented and analysed. Second, we build concentration indexes and other indicators of competitiveness. Finally, we conduct an econometric analysis to determine the extent to which regulatory measures, privatization, market structure and the population dimension determine market shares. Overall, we can argue that, although concentration remains high, the market has become more competitive since the liberalization process began. The statistical analysis and the econometric assessment show that the entrance of the third operator made the market more competitive. Indeed, there is evidence that operator companies competed to capture customers from each other during the period under study. These features suggest that mobile operators did not follow anticompetitive practices in order to restrain competition.     

An institutional analysis of environmental management in the Korean mobile communications industry

Environmental sustainability in the mobile communications industry can affect corporations not only in the sector but also in other industries by providing solutions to cope with environmental issues. However, despite the significance of environmental sustainability in the industry, there has been a lack of academic attention. This study investigated the environmental issues in the mobile communications industry by adopting an integrated and holistic approach to corporate sustainable management. In addition, the environmental management of mobile network operators was analyzed using the framework of institutional theory. To investigate the environmental management of mobile network operators, we carried out a case study on three Korean mobile network operators including SK Telecom, KT, and LG Uplus. The results demonstrated that economic and environmental issues were mostly found in the mobile communications industry, and the mobile network operators have actively coped with these issues. Their environmental management was relatively active, and regulatory, mimetic and normative mechanisms were working simultaneously. This study provides some meaningful implications for practitioners and policymakers.     

Customer churn analysis: Churn determinants and mediation effects of partial defection in the Korean mobile telecommunications service industry

Retaining customers is one of the most critical challenges in the maturing mobile telecommunications service industry. Using customer transaction and billing data, this study investigates determinants of customer churn in the Korean mobile telecommunications service market. Results indicate that call quality-related factors influence customer churn; however, customers participating in membership card programs are also more likely to churn, which raises questions about program effectiveness. Furthermore, heavy users also tend to churn. In order to analyze partial and total defection, this study defines changes in a customer's status from active use (using the service on a regular basis) to non-use (deciding not to use it temporarily without having churned yet) or suspended (being suspended by the service provider) as partial defection and from active use to churn as total defection. Thus, mediating effects of a customer's partial defection on the relationship between the churn determinants and total defection are analyzed and their implications are discussed. Results indicate that some churn determinants influence customer churn, either directly or indirectly through a customer's status change, or both; therefore, a customer's status change explains the relationship between churn determinants and the probability of churn.
