40 years on: An account of innovation in the regulation of UK telecommunications,in 3½ chapters

The past nearly 40 years have seen major developments in telecommunications networks and services, and in how they are regulated. This paper describes innovations in UK telecommunications regulation which have taken place over the period, broken down into stages, beginning with the regulation of the former monopolist by an independent regulator under a price cap, continuing the regulation first of mobile and then, under European Directives, of copper-based broadband, and ending with the diffusion of fibre networks. It is argued that a variety of changes have reduced the scope of innovation over the period, including domestic institutional reform, the limits placed on later decisions by earlier ones (path dependency), and the constraining impact of European Union law and regulation. The paper concludes with some consideration of the effects on future innovation of the UK’s withdrawal from the EU.     

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.     

Evolution and determinants of digital divide in Brazil (2005–2013)

During the last decades, the widespread growth of information and communication technologies (ICT) has posed incentives to broaden the participation of individuals in social, political and economic dimensions of life. However, utilization of ICT also involves access to technology and infrastructure, and acquisition of skills to deal with innovations and, thus, digital literacy is, primarily, a complementary good. The digital divide expresses inequalities in access and utilization of ICT among individuals and populations in different countries. The study adopts inequalities indexes of Internet access and mobile phone ownership to measure use of ICT goods, accounting for the digital divide in Brazil. The inequality indexes are also split according to main determinants using four nationally representative survey data from 2005 to 2013. Results indicate that the digital divide among individuals is decreasing quite fast among Brazilians over time. However, there is room for policies of mass access to ICT goods based on mobile Internet broadband access. In addition, digital illiteracy, evaluated by lack of education, is one of the main determinants of the digital divide in the country, especially among elderly individuals.

Planning and implementing effective mobile marketing programs

Mobile marketing is an ever increasingly important component of a firm's overall promotional strategy. The importance of this medium can be seen through time spent on mobile media, number of searches, and direct and indirect mobile-generated sales. Despite its increased importance, the effectiveness of mobile marketing needs to be improved based on such metrics as bounce rates, add-to-cart rates, shopping cart abandonment, and average order size. Strategies to increase the effectiveness of mobile marketing are discussed. Firms need to capitalize on the three major strategic advantages of mobile marketing: (1) the fact that mobile marketing devices are always on, always connected, and always with the consumer; (2) the ability to generate location-sensitive offers; and (3) the ability to send relevant personalized messages and offers. Firms also need to develop and implement an effective mobile marketing strategy through a series of activities. These include understanding and reacting to the complexity of mobile marketing, designing sites based on ease of use versus ‘bells and whistles,’ increasing opt-in rates, using effective customer engagement strategies, and developing effective mobile coupons. Criteria to evaluate the effectiveness of mobile marketing are discussed.     

Mobile marketing: A literature review on its value for consumers and retailers

The article describes the existing knowledge of how mobile marketing can increase the value for consumers and retailers. Mobile device shopping, and consumers' use of mobile devices while shopping is shown to be both an extension of consumers' shopping behaviours developed on Internet-connected desktop and laptop computers (PC), and potentially new behaviours based on a mobile devices' uniquely integrated features such as camera, scanners and GPS. The article focuses on how mobile marketing creates value for consumers and retailers, enabling more precise research and development of managerial concepts and tools while providing both managers and academics with increased understanding of mobile marketing and its value outcomes for retailers.     

On regulations for 5G: Micro licensing for locally operated networks

Future 5G networks aim at providing new high-quality wireless services to meet stringent and case-specific needs of various vertical sectors beyond traditional mobile broadband offerings. 5G is expected to disrupt the mobile communication business ecosystem and open the market to drastically new sharing based network operational models. 5G technical features of network slicing and small cell deployments in higher carrier frequencies will lower the investment barrier for new entrants to deploy local radio access networks and offer vertical specific services in specific areas and allow them lease the remaining required infrastructure on demand from mobile network operators (MNO) or infrastructure vendors. To realize the full vision of 5G to benefit the society and promote competition, innovation and emergence of new services when the 5G end-to-end network spans across different stakeholders administrative domains, the existing regulations governing the mobile communication business ecosystem are being refined. This paper provides a tutorial overview on how 5G innovations impact mobile communications and reviews the regulatory elements relevant to 5G development for locally deployed networks. This paper expands the recent micro licensing model for local spectrum authorization in future 5G systems and provides guidelines for the development of the key micro licensing elements. This local micro licensing model can open the mobile market by allowing different stakeholders to deploy local small cell networks with locally issued spectrum licenses ensuring pre-defined quality guarantees for the vertical sectors’ case specific needs.

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.
