Reducing the level of switching costs in mobile communications: The case of Mobile Number Portability

Switching costs are one of the most important economic forces that affect market competition in mobile communications. Both theoretical and empirical studies have shown that switching costs reduce market competition leading to higher prices, lower product and service quality, and lower customer welfare. Given their negative consequences, national regulatory authorities have designed policies aimed at reducing switching costs and fostering competition. One of the most important of these, in the mobile communications industry, is mobile number portability (MNP). The aim of this paper is to investigate the effect of MNP on switching costs in mobile phone services. First, a hierarchical Bayes model is proposed to measure switching costs at the customer level and to investigate the impact of MNP on them. Second, this study examines the drivers of MNP adoption by customers using a binary logit specification. The results reveal that this regulatory policy has significantly reduced the cost of switching and that MNP adoption partially depends on customer-related variables.     

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.     

Technical innovation and 3.5 mobile phone generation: Lessons from Korea

In 1996, the Korean mobile communication market was the first in the world to commercialize the code division multiple access (CDMA). Since then, the voice-based mobile phone market has continued to grow and has now reached near saturation. Having recognized the potential of the mobile data service as a new source of profit, telecommunication operators are scrambling to evolve 3.5 generation (3.5G) technology in order to lead market competition. Recently, the Korean 3.5G mobile telecom market has faced stiff competition from CDMA-based EVDO Rev.A and global system for mobile telecommunications (GSM)-based high-speed downlink packet access (HSDPA). In addition, the world's first wireless LAN-based wireless broadband internet (WiBro) service was commercialized in June, 2006. This paper reviews the current status of the 3.5G technology and analyzes the service standardization strategies from the viewpoint of technological evolutions. This paper also suggests implications for Korea's specific circumstances where different mobile telecom technologies complement and compete with one another. Korea's experiences may serve as important lessons for other countries or operators who try to introduce the 3G and look beyond mobile telecom technologies.

Estimating demand for cellular phone services in Japan

Since the 1990s, the telecommunications industry has changed dramatically with the wide diffusion of mobile telecommunications. In spite of this, the nature of the cellular phone market has not yet been explored sufficiently. This paper analyzes the demand for cellular phone services using data on the Japanese cellular phone market in the late 1990s. It finds that the market is highly product-differentiated and conventional network externalities are no longer decisive factors in choosing a mobile phone carrier. The evidence also shows that the demand for cellular phone services is quite price-elastic, with estimated elasticity from 1.30 to 2.43 in absolute value.

Termination-discriminatory pricing,subscriber bandwagons,and network traffic patterns: the Taiwanese mobile phone market

This article studies network effects induced by termination-based price discrimination in the evolving Taiwan mobile phone market. An econometric model that estimates the effects attests to the formation of bandwagon behavior among network subscribers. It is shown that networks with a large subscriber base will recruit a disproportionately greater share of new users ceteris paribus compared with low-penetration operators. The strength of the subscriber bandwagon varies closely with the price differential of intra- and inter-network calls. Also, analysis of network traffic reveals that an average mobile phone user consumes considerably less inter-network than intra-network airtime; consequently, mobile phone use is largely clustered within respective networks and hindered from traversing others.     

Concentration of the mobile telecommunications markets and countries’ competitiveness

This study examines how the level of concentration of a country’s mobile telecommunications market affects its competitiveness. We created a unique database with information on 59 countries, which we used to perform several estimations including an instrumental variable approach to explain the degree of concentration in mobile phone markets. Our first and direct estimation shows that the higher the concentration in this industry, the lower the countries’ competitiveness. In order to understand this positive correlation, we provide two additional estimations. First, using an instrumental variable, we find that the concentration in mobile telecommunications market explains the use of information and communications technology (ICT). Moreover, we also find that the use of ICT is positively correlated with countries’ competitiveness. Thus, our results confirm that the mobile phone industry has positive spillover effects on countries’ competitiveness and demonstrate the benefits of policies designed to reduce concentration and market power in the industry.

Predation and network based price discrimination in Chile

This paper uses a model of strategic interaction among firms –that set discriminatory and nonlinear prices– in addition to public information on prices of the plans marketed by the three major mobile phone companies, to assess the extent to which on-net/off-net price differentials in the plans they offered could represent predatory practices in the mobile telephony market in Chile. The results show that the largest companies offered a few plans with an off-net/on-net price differential larger than what a competitive theoretical model predicts. This larger differential is consistent with the notion of predation defined by Hoernig (2007) as reducing a competitor's profits. Despite the fact that these plans were a small fraction of all the plans mobile phone firms offered, they were recently banned by the antitrust authority because of their potential anticompetitive effects.     

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.     

Pricing of mobile phone attributes at the retail level in a developing country: Hedonic analysis

This study has been undertaken to determine the effect of mobile phone attributes on their retail market prices. A log-linear hedonic price model was fitted to a total of 348 handsets, for which data were collected about various attributes from different websites, while the price data were obtained from mobile phone retailers in two major cities of Pakistan from November 2016 to February 2017. Results indicate that brand, battery capacity, weight, operating system, RAM, memory size and display size have a significant positive effect on mobile phone prices. Given the significant premium associated with various characteristics, manufacturers need to formulate strategies to emphasize the battery capacity of 2000-3000?mAH, RAM of more than 1GB, screen size of more than 5 inches, memory size of more than 8GB, back camera of over 15MP, 4G network mode, front camera and FM radio.     

Mobile number portability in Europe

This paper examines the causes and effects of mobile number portability (MNP) and provides a survey of its implementation in Europe. It first examines the competitive effects and costs of introducing MNP. Next, it discusses how to charge for MNP. It argues that a price cap regime starting from the average cost of porting is likely to provide appropriate incentives. Finally, it reviews recent experience with implementing MNP in Europe. Differences in the speed of porting and porting charges appear to explain part of the differences in the use of MNP across countries.     

Can mobile phones improve gender equality and nutrition? Panel data evidence from farm households in Uganda

Since 2000, mobile phone technologies have been widely adopted in many developing countries. Existing research shows that use of mobile phones has improved smallholder farmers’ market access and income. Beyond income, mobile phones can possibly affect other dimensions of social welfare, such as gender equality and nutrition. Such broader social welfare effects have hardly been analyzed up till now. Here, we address this research gap, using panel data from smallholder farm households in Uganda. Regression results show that mobile phone use is positively associated with household income, women empowerment, food security, and dietary quality. These results also hold after controlling for possible confounding factors. In addition to the household-level analysis, we also look at who within the household actually uses mobile phones. Gender-disaggregation suggests that female mobile phone use has stronger positive associations with social welfare than if males alone use mobile phones. We cautiously conclude that equal access to mobile phones cannot only foster economic development, but can also contribute to gender equality, food security, and broader social development. Further research is required to corroborate the findings and analyze the underlying causal mechanisms.     

Competition reform and household welfare: A microsimulation analysis of the telecommunication sector in Ethiopia

This paper presents a novel simulation method for estimating the likely welfare effects of policy reforms aimed at increasing competition in strategic economic sectors such as mobile phone services. The proposed method relies on a partial equilibrium simulation approach and estimates the welfare impacts on current consumers and the potential welfare effects among new consumers brought into the market by changes in prices due to competition. This approach is applied to the information and communication technology (ICT) sector in Ethiopia, one of the three countries in the world with a monopoly in the market for mobile phone services. Based on household budget survey data for 2015/16 and departing from a baseline reform scenario that dilutes the market share of the state-owned monopoly to 45 percent, the simulation model estimates a 25.3 percent reduction in the price of mobile services and an increase in 5.7 million new users of mobile services. The predicted drop in prices and increased users would generate a combined relative welfare gain of 1.18 percent (1.09 percent among current users and 0.09 percent among new users), that could be translated into a 0.31 percentage point decline in the national poverty rate and equivalent to lifting about 275,000 people out of poverty. Alternative reform scenarios that dilute the market share of the monopoly to 75 percent and to 30 percent are expected to reduce poverty rate in 0.13 and 0.52 percentage points, respectively. The method proposed in this study represents a useful tool for promoting competition reforms in developing countries, particularly in sectors known for excluding significant segments of the population because of high consumer prices.     

Diffusion of mobile telephony: Analysis of determinants in Cameroon

This paper explores the diffusion of mobile telephone technology in Cameroon by identifying and analyzing the determinants of this diffusion. Studying the diffusion of mobile communications in African countries by integrating them into panels of developing countries is problematic. This approach is likely to mask the intrinsic differences as concerns the diffusion process. This survey shows, through the estimation of an S-shaped growth curve, that the Logistic model best describes the diffusion of mobile phone technology in Cameroon. Income, openness to competition and the use of SMS are key forces driving this diffusion. Forecasts indicate an increase of almost 70% in the demand by 2026 as far as mobile phone use in Cameroon is concerned. This implies not only an improvement in operators' and State's revenues, but also, the need to invest in infrastructures. Our recommendation therefore calls for a greater liberalization of the mobile phone market in Cameroon. In addition, given the complementary relationship between the core and the mobile networks, infrastructural investments are also needed in both sectors.

The emerging value network in the mobile phone industry: The case of Japan and its implications for the rest of the world

This paper considers how the mobile phone industry is changing from a value chain to a value network using the Japanese market as an example. Value networks involve a larger number of firms, a more complex set of relationships between them, and agreements on a greater number of interface standards than do value chains. Building from this concept of a value network, the paper shows how: (1) agreements on many of these interface standards are enabling connections to be made between the mobile phone and other industries; (2) the resulting products and services often reflect the technological capability of phones and the existing products and services in these “other” industries; (3) each new interface standard requires a new critical mass of users; and (4) a critical mass of users for a new interface standard partly builds from previously created critical masses of users. On a practical level, this paper's analysis adds to a growing list of evidence that the growth in Western mobile Internet markets is nowhere near its potential and that the change from a value chain to a value network requires a different form of standard setting, policy making, and management than are currently used in the mobile phone industry.     

Determinants of mobile phone ownership in Nigeria

Mobile phones are recognized as a primary platform for mitigating the digital divide and increasing economic growth, and the same appears to be true for Nigeria, the largest economy in Africa. Since 2012, mobile phone penetration has shown nearly linear growth, reaching 83% in 2016. However, this statistic falls to only 46% after correcting for ownership of multiple SIM cards and sharing of mobile phones among multiple users. The determinants of mobile phone ownership in Nigeria are poorly understood, which hinders research that could inform policies capable of increasing mobile phone penetration and eliminating the digital divide. To begin to fill this research gap, we have analyzed socio-economic factors related to mobile phone ownership in the country. We used a logit model and the latest national-level Datafirst ICT dataset (2012) about mobile phone adoption from 1552 individuals. The sample was stratified, clustered, and probability-weighted to make it representative of the situation at the national level. The results suggest that factors such as geographic location and income may not strongly influence mobile phone ownership, in contrast to what was previously thought. Instead, the strongest factors appeared to be education level, informal work, social engagement, type of electricity supply and employment status. Our analysis suggests that to increase mobile phone ownership and close the digital divide, policy makers should target younger adults, provide training in digital literacy specifically for mobile phone use, invest in electricity supply infrastructure, and develop content and applications in non-English languages. These findings may contribute to understanding mobile phone distribution in Nigeria as well as inform implementation of the country's ICT Roadmap 2017–2020 and Vision 2020.
