Mobile phones,mobile Internet,and employment in Uganda

We analyze the relation between mobile phone use – mobile Internet in particular – and employment, self-employment and job regularity in Uganda. We find no evidence of any positive impact of mobile Internet use on employment or job quality, suggesting that either respondents do not use mobile Internet for job search practices or as a job tool, or that these uses are ineffective. However, we find that the adoption and use of basic mobile phones are positively related to employment and job quality, and we argue that regulators should focus on promoting the affordability of basic phones and mobile airtime.     

Roaming and investments in the mobile internet market

This model discusses mobile network operators' (MNOs) incentives to invest in their network facilities such as new 4G networks under various regimes of data roaming charge regulation. Given an induced externality of investments (spillovers) due to the roaming agreements it will be shown that MNOs, competing on investments, widely set higher investments for below cost regulation of roaming charges. Otherwise, if MNOs are free to collaborate on investments, they set higher investment levels for above cost roaming charges. Both below and above cost charges may be preferred from a welfare perspective. Furthermore, the paper discusses effects of the roaming charge regulation on roaming quality and MNOs' coverage.     

Regulation of international roaming in the European Union—Lessons learned

This paper analyzes the evolution of prices and competition in intra-EU international roaming markets. It addresses three main research questions: (i) to what extent have market forces by themselves brought competition to retail roaming markets? (ii) Has the evolution of market dynamics in wholesale roaming improved competition? (iii) Is wholesale regulation sufficient to lead to a reduction in retail roaming prices? Data show that there has been little price-based competition both at wholesale and retail levels, despite prices being well above costs and the significant margins allowed by regulation. Available data from the period preceding the entry into force of the first EU roaming regulation also point to the same conclusion. Lack of competitive pressure in retail roaming markets and inelastic demand give little incentives for retail roaming service providers to lower prices. Wholesale international roaming markets have complex competition dynamics. They are characterized by the reciprocity of wholesale roaming agreements and traffic internalization inside transnational groups. These circumstances limit price competition at the wholesale level. The traditional regulatory approach applied to electronic communication markets has been primarily focused on wholesale regulation. However, empirical evidence shows that even if wholesale charges are reduced, retail roaming markets continue to operate at very high retail margins (for example, more than 200% retail mark-up over wholesale charges for data roaming services and incoming calls). This proves that in international roaming markets wholesale charge reductions are not necessarily passed on to retail prices. It can thus be inferred that wholesale price regulation alone is in most cases not sufficient to ensure that benefits are passed through to end users.     

Solving the startup problem in Western mobile Internet markets

This paper describes the evolution of the mobile Internet in terms of three concepts: the startup problem, standard setting, and mental models. Products in which there is little or no value to the first users due to the existence of strong direct (e.g., telephone) or indirect (complementary products) network effects face a large startup problem. This paper divides the startup problem for the mobile Internet into two stages. Japanese and later other service providers solved the first startup problem with entertainment content that was supported by a micro-payment system (service providers collect and pass on content fees to content providers) and custom phones that displayed this content in a consistent manner.     

Mobile phones,the Internet and the institutional environment

This paper empirically investigates the determinants of the Internet and cellular phone penetration levels in a cross-country setting. It offers a framework to explain differences in the use of information and communication technologies in terms of differences in the institutional environment and the resulting investment climate. Using three measures of the quality of the investment climate, Internet access is shown to depend strongly on the country's institutional setting because fixed-line Internet investment is characterized by a high risk of state expropriation, given its considerable asset specificity. Mobile phone networks, on the other hand, are built on less site-specific, re-deployable modules, which make this technology less dependent on institutional characteristics. It is speculated that the existence of telecommunications technology that is less sensitive to the parameters of the institutional environment and, in particular, to poor investment protection provides an opportunity for better understanding of the constraints and prospects for economic development.     

Internet peering as a network of relations

This paper applies results from recent theoretical work on networks of relations to analyze optimal peering strategies for asymmetric Internet Service Providers (ISPs). From a network of relations perspective, ISPs’ asymmetry in bilateral peering agreements need not be a problem, since when these form a closed network, asymmetries are pooled and information transmission is faster. Both these effects reduce the incentives for opportunism in general, and interconnection quality degradation in particular. The paper also explains why bilateral monetary transfers between asymmetric ISPs (Bilateral Paid Peering), though potentially good for bilateral peering, may have negative effects on the sustainability of the overall peering network.     

Impacts of mobile Internet use intensity on the demand for SMS and voice services of mobile network operators: An empirical multi-method study of German mobile Internet customers

Scholarly and business publications alike convey the message that past and future strong growth in mobile Internet (MI) access and service demand has solely positive commercial implications for mobile network operators (MNOs). This position neglects the possibility that increasing MI use intensity may lead to demand decreases for the highly profitable short messaging service (SMS) and mobile voice telephony. The extant literature provides few insights on relations between MI use intensity, on the one hand, and SMS as well as mobile voice call use intensities, on the other hand. This study developed hypotheses concerning the presence or absence of impacts of MI use intensity and circumstances of MI use (e.g., device type, tariff scheme) on the demand for SMS and mobile voice telephony at the individual customer level. The hypotheses were tested by analyzing actual use behaviors of 304 MI adopters in Germany, for whom objective use intensity data were extracted from the billing system of an MNO. These non-reactive measures were combined with responses collected from the adopters through a telephone survey. Multivariate regression results suggest that though MI use intensity significantly negatively affected both number of SMS sent and received, these effects were so small that their practical relevance is highly doubtful. Further, customers who used MI more intensively did not generate lower volumes of outgoing or incoming mobile voice connection minutes. Conclusions are drawn for MNO, telecommunications sector regulators and scholarly researchers seeking to explain the acceptance of mobile communications services.     

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.     

Fixed-to-mobile substitution in the European Union

This paper analyzes substitution between access to fixed-line and mobile telephony in the European Union using cross-section panel data on households’ choices of telecommunications technologies in years 2005–2010. We estimate a structural model of household?s demand for access to: (i) fixed-line only; (ii) mobile only; and (iii) both fixed-line and mobile. We find that growing Internet usage increases the share of ‘fixed + mobile’ households, which suggests that households keep their fixed-line connection to access Internet. However, the spread of 3G and cable broadband access decreases the share of ‘fixed + mobile’ households and increases the share of ‘mobile only’ households. Hence, fixed-to-mobile substitution was slowed down by the spread of Internet but it may continue with the spread of mobile broadband. Furthermore, bundling of telecommunications services increases the share of ‘fixed + mobile’ households and decreases the shares of ‘mobile only’ and ‘fixed only’ households. Therefore, operators which can bundle fixed-line connection with Internet or mobile services may slow down fixed-to-mobile substitution.     

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.     

Mobile service innovation: A European failure

The continuing absence of innovation in Europe’s mobile services industry is identified and characterised here, with such examples as mobile Internet and mobile music. Innovation failure is a critical factor leading to a lack of high-income jobs, network effects, and price reductions for data services. Most mobile service innovations have been made in Japan in ‘clubs of operators’ with their suppliers. Apple USA followed the same model of control with its iPhone. Conversely, a lack of this critical type of competition characterises European operators. Revenues per citizen are in some countries similar to those in Japan, but with handsets with less functions. Europe and all other regions face the challenge of competing with Japanese and US innovators. The lessons to be learned are (1) becoming aware of the situation, (2) allocating spectrum that covers a sufficient population size to allow technological competition, and (3) developing a strong customer orientation.     

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.     

Mobile money,family assistance and welfare in Cameroon

This paper aims to investigate the effect of mobile money services on the welfare in Cameroon. It specifically verifies whether the welfare of people benefiting from family assistance is improved via the mobile money services offered by the two main operators in the country, namely: Orange and Mtn. The data used come from the « FinScope Consommateur Cameroun » Survey carried out in 2017 by the National Institute of Statistics (INS). Based on the propensity scores estimations, this study shows a positive and significant effect of mobile money on welfare. However, among the operators, Orange has a better impact compared to Mtn which does not present a significant effect. These results call on the authorities in charge of the development and implementation of financial inclusion policies to recognize the interest of digital financial services at the heart of financial inclusion strategies for the welfare of the poor.     

Business ecosystem strategies of mobile network operators in the 3G era: The case of China Mobile

In order to define the mobile network operators' strategies of building value network in the 3G era, this paper applies the ecosystem principles to the mobile industry through a China Mobile case study. Based on an analytical framework of such principles, this paper reviews China Mobile's ecosystem, and identifies its success factors and problems. The results indicate that a complete ecosystem, where mobile network operators collaborate closely with value-added service providers, content/application providers, equipment and device manufacturers, and other involved organizations, can promote the development of mobile data services substantially. Therefore, mobile network operators should play a central role in the ecosystem by managing the entire value-chain and setting up proper value-sharing mechanisms. However, while doing so, problems may arise because of regulatory issues and information asymmetry. High-value common assets, a centralized management system, partner selection schemes and continuous innovations are important success factors.

Leadership with 5G in Europe: Two contrasting images of the future,with policy and regulatory implications

European policy makers have shown a keen interest in the success of 5G because ubiquitous and high capacity electronic communication infrastructure is recognized as a cornerstone of economic development and productivity growth. The second generation, GSM, is considered the leading example, reaching its peak of deployment in 2015 with 3.83 billion subscribers served by over 700 operators in 219 countries and territories.With 5G rapidly shaping up in the R&D and standardization environments, and a call for leadership with 5G in Europe by policy makers, it is timely to investigate what lessons can be learned from the success of 2G that can be applied to 5G. More broadly, this calls for research into the commonalities and differences between successive generations of mobile technology, their introduction and the market adoption that followed. This also calls for an investigation into the possibility of multiple futures of 5G and how that impacts the opportunity for leadership. As one future may be more desirable than the other, depending on the perspective of the actor involved, a policy debate will be required to determine the most desirable future. As well as a discussion of the policy and regulatory actions required to enable a particular future.Hence, the two-part research question being addressed in this paper is: What explains the success of 2G-GSM and how can it be applied to create success with 5G in the European Union?To respond to the research question this paper first identifies the leadership lessons to be drawn from the success of 2G-GSM in relation to its successors 3G and 4G. Secondly, the contribution describes two stylized images of possible futures of 5G, called “Evolution” and “Revolution”, as input to the policy debate on the options for leadership with 5G. These images reflect two extremes in terms of possible futures of 5G. “Evolution” follows the pattern of previous generations and current trends. “Revolution” represents a clear break with these trends and a path towards leadership with 5G, as it exploits the opportunities of standardized APIs for service creation, being enabled by network virtualization as an architectural foundation of 5G. These open and uniformly applied APIs allow the market entry of a multitude of virtual mobile network operators (VMNOs) serving particular industry verticals or economic sectors with tailored feature sets and qualities of services. They allow a market momentum to be built that constitutes leadership with 5G in Europe.     

Push-button-autocracy in Tunisia: Analysing the role of Internet infrastructure,institutions and international markets in creating a Tunisian censorship regime

Internet censorship and control have been commonplace in Tunisia since the Internet became available to then public in 1996. It was not until the last days of the Jasmine revolution in January 2011 that the Tunisian government shut down the censorship regime, raising numerous questions about Internet censorship in Tunisia. This article will look at how former Tunisian president Ben Ali was able to shut down the Internet censorship regime within a matter of hours. In order to answer this question, it looks at the history of the Tunisian Internet and its Internet censorship regime, before analysing Internet architecture, Internet institutions, functional differentiation between elements of the regime and the role of international technology markets. Each of these factors contributes to the overall censorship regime and helps understand how former President Ben Ali was able to shutdown Internet censorship within a matter of hours. In conclusion, tracing the genesis of the Tunisian censorship regime may contribute to understanding the role of institutional, architectural and market-based factors in enabling other censorship regimes across the world.
