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.     

Analysis of the socio-economic determinants of mobile money adoption and use in Cameroon

This study analyses the adoption and use of mobile money (MM) services based on data collected on 1000 households from the Global Findex Survey conducted in 2017 in Cameroon, by the World Bank. More specifically, this study attempts to first profile MM adopters, and then identify the explanatory factors of the different uses of these services. A Probit model is used to highlight the explanatory factors of MM adoption combined with multivariate regressions to identify the determinants of MM service use. Then, estimates of three independent Probits, under the assumption of non-simultaneity of the different uses of MM services are done to test the reliability and robustness of the results. The results reveal that socio-economic factors such as age, level of education, the standard of living and mobile phone ownership differentially affect both the adoption and use of MM services in Cameroon.     

Antecedents of consumers’ intentions to upgrade their mobile phones

The fourth generation (4G) mobile phone will soon be launched. Marketers need to know which factors determine whether customers choose to upgrade their mobile phones, as this will affect the diffusion of third generation (3G), 4G, and Worldwide Interoperability for Microwave Access phones. This study integrates pre- and post-adoption theories, upgrading, and value-based theory to examine plans to upgrade to a newer model mobile phone among second generation (2G) and 3G mobile phone users. The empirical results show that the technology acceptance model fails to explain consumers’ intentions to upgrade in sequence. Although customers perceived next-generation mobile phones as being easier to use and more useful than their current model phones, this did not directly influence them to upgrade. When users were satisfied with their current model, they were not willing to upgrade to a newer generation model. Moreover, value assessments affect users’ plans to upgrade to next-generation mobile phones.     

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.     

Lopsided effects of telecom reforms on mobile markets in the enlarged EU: Evidence from dynamic quantile model

The European Union (EU) has recently been significantly enlarged with addition of ten countries, almost all from Central and Eastern Europe (CEE). This was expected to enhance the performance of the mobile telecommunications industry in the accession countries and in turn to consolidate the highly fragmented European mobile telecoms market to finally reach the single market goal. However, the significant differences between mobile telecommunication performances from one country to another in the enlarged European area raise the issue of how optimal and durable the EU-level reforms have been. We use dynamic quantile regression methods to estimate the effects of mobile telecommunication reforms on the providers' performance in the EU enlargement context. This approach allows uncovering potential asymmetric effects of telecom reforms policy by letting the parameters of regressions vary across the conditional distribution of the sector's performance indicators. Using annual data from on 32 European countries from 1993 to 2011, we document asymmetrical responses to the reforms depending on the conditioning quantile at which they are calculated. Our results show that the effects of the generic and imposed European reforms are notably beneficial and larger for players in developed European countries characterized initially by real and higher degree of the reforms implementation. Accordingly, the success and durability of European reforms, especially in the new CEE member states, which often fail to comply with the pace of the reforms' adoption of industrialized European countries, is not guaranteed when countries specifications are not sufficiently taken into account. A final appealing result regarding the regress of the reform-performance relationship in the mobile markets after enlargement even for western countries attract attention on revising the Europe's current approach to telecoms regulation.     

Is better access to mobile networks associated with increased mobile money adoption? Evidence from the micro-data of six developing countries

In several developing countries in Sub-Saharan Africa, accessibility to digital financial services is increasing because of the development of mobile money services. People previously excluded from the financial system have started to have access to financial services such as receiving and sending remittances, saving, and borrowing. This study examines the effect of network accessibility on the use of mobile money in six developing countries (Bangladesh, Kenya, Nigeria, Pakistan, Tanzania, and Uganda) using GPS information on each household and mobile phone network coverage maps. We find that among these six countries, network accessibility is associated with the use of mobile money in a robust way only in Pakistan and Tanzania. In those two countries, when a household location becomes 10 km closer to the center of the area with multiple mobile networks, the probability of using mobile money increases by 10 percent. In the other countries, we did not find a robust relationship between the use of mobile money and network accessibility. This suggests that increasing network accessibility may not be an efficient method for increasing mobile money adoption in certain countries. The fact that mobile money use rates differ between Tanzania and Pakistan also suggests that the effect of mobile networks is unrelated to the overall level of mobile money adoption.     

User-oriented design for the optimal combination on product design

This paper presents a new approach of user-oriented design for transforming users’ perception into product elements design. An experimental study on mobile phones is conducted to examine how product form and product color affect product image individually and as a whole. The concept of Kansei Engineering is used to extract the experimental samples as a data base for Quantitative Theory Type I and neural networks (NNs). The result of numerical analysis suggests that mobile phone makers need to provide various product colors to attract users, in addition to product forms. This paper demonstrates the advantage of using NNs for determining the optimal combination of product form and product color, particularly if the product into design elements. Based on the analysis of NNs, we can use 72 representative product colors of each mobile phone to develop a product color data base consisting of 16777216 (=256×256×256, True-Color model) colors with the associated product image. The design data base provides useful insights to save any amount of money and time for the new product development. The product designers can input a product image to work out an adequate color on a mobile phone. Furthermore, the design data base can be used, in conjunction with computer-aided design system or virtual reality technology, to build a 3D model for facilitating the design process of mobile phones. Although, the mobile phones are chosen as the object of the experimental study, this approach can be applied to other products with various design elements.     

Foreign direct investment,information technology and economic growth dynamics in Sub-Saharan Africa

The research assesses how information and communication technology (ICT) modulates the effect of foreign direct investment (FDI) on economic growth dynamics in 25 countries in Sub-Saharan Africa for the period 1980–2014. The employed economic growth dynamics are Gross Domestic Product (GDP) growth, real GDP and GDP per capita while ICT is measured by mobile phone penetration and internet penetration. The empirical evidence is based on the Generalised Method of Moments. The study finds that both internet penetration and mobile phone penetration overwhelmingly modulate FDI to induce overall positive net effects on all three economic growth dynamics. Moreover, the positive net effects are consistently more apparent in internet-centric regressions compared to “mobile phone”-oriented specifications. In the light of negative interactive effects, net effects are decomposed to provide thresholds at which ICT policy variables should be complemented with other policy initiatives in order to engender favourable outcomes on economic growth dynamics. Practical and theoretical implications are discussed.     

Determinants of mobile broadband use in developing economies: Evidence from Sub-Saharan Africa

Broadband is seen as a vector of economic growth and social development. In the developing world, mobile technologies are widely adopted and mobile broadband is progressively rolled-out with high expectations on its impact on the countries’ development. We highlight what the determinants of mobile broadband use are in four Sub-Saharan countries. Using micro-level data coming from household surveys over 5 years, from 2013 to 2017, we show that SIM card ownership and being part of an online social community has a strong positive impact on mobile broadband use. We also highlight a positive correlation between digital inclusion and financial inclusion as mobile money users and bank account users are found to be more inclined to use mobile broadband. However, beyond apparent similarities, mobile broadband is used in different ways according to countries specificities. For instance, among the non-mobile owners in Nigeria, the unemployed are the most likely to use mobile broadband, most probably for job search practices, while it is rather used by students for information gathering in other countries. Finally we show that those excluded from mobile broadband use are the eldest, those with the lowest level of education, and women.     

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.     

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.     

Diffusion of digital mobile telephony: Are developing countries different?

Factors determining the diffusion of digital mobile telephony across developed and developing countries are studied with the aid of a Gompertz model. After controlling for other factors, the speed of diffusion per se is not significantly different between the two groups of countries. Standards competition hinders and market competition promotes diffusion in both groups. Various factors are, however, more important in a developing country context: having a large potential user base, accumulating network effects, being open, commanding a high (non-telecom) technological level, and introducing innovation(s) complementing mobile telephony. Late entrants experience faster diffusion promoting cross-country convergence.     

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.     

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.     

From the wired to wireless generation? Investigating teens’ Internet use through the mobile phone

Scholars have an enduring interest in investigating whether a new medium displaces or complements existing media whenever a new medium is introduced to the society. In this study, it is sought to investigate the extent to which the mobile phone would replace or reinforce teens’ traditional Internet use through computers. Surveys were conducted on 1875 youths between 12 to 17 years old in 5 digital cities in East Asia: Hong Kong, Seoul, Singapore, Taipei, and Tokyo. The findings profile a digital generation that is highly connected in the 21st century. Ninety percent of all respondents used the Internet. Almost 90% of the teens in this study used the mobile phone, and two-thirds of them ever surfed the Web via their mobile devices. Through a factor analysis, three dimensions of teens’ use of mobile Internet were identified, namely, task-based activities, information seeking and communication activities, and recreational activities. In general, the teens tend to use the mobile phone for recreation and entertainment purposes, especially playing games and listening to music. They are less likely to use the mobile phone for more sophisticated purposes, such as petitioning, voting, or shopping. Drawing upon the niche theory, the patterns between teens' mobile Internet and PC Internet use were further compared. Our analysis shows that mobile Internet primarily serves as an extension of teens’ Internet activities via PC, rather than as a replacement. Such positive relationships are quadratic and non-linear.     

An estimation of the pattern of diffusion of mobile phones: The case of Colombia

This paper examines the diffusion pattern of mobile telephony in Colombia. The empirical modelling approach adopted in the paper starts off by choosing between the two functional forms that are most frequently used in the literature, namely the Gompertz and the Logistic models. After applying a formal statistical test to choose the preferred functional form, the evidence suggests that the pattern of diffusion can be best characterised as following a Logistic model. The findings also suggest that despite the fact that in recent years the rate of growth of mobile phone subscribers has started to slow down, there still appears to be room for further expansion as the saturation level is expected to be reached in 2013. The estimated saturation level is consistent with some individuals possessing more than one mobile device.     

User benefits and operator costs of mobile number portability in Japan and impact on market competitiveness

This paper aims to review the process of mobile phone operators agreeing to introduce mobile number portability (MNP) in Japan. A study group formed by the Ministry of Internal Affairs and Communications estimated the proportion of MNP users and analyzed the user benefits and associated costs to introduce MNP. Owing to the particular market structure and technology available, MNP was expected to yield a larger benefit in the Japanese mobile market than that seen in other countries. Based on the results of the research reviewed with respect to the market situation one year after introducing MNP, the increased competition in the mobile phone market was onfirmed by decreasing call charges and a reduction in the share of the dominant operator.     

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.
