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.     

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.     

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.     

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.     

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.     

Information communications technology and economic growth in Sub-Saharan Africa: A panel data approach

This research empirically analyzed the impact of mobile phone and the Internet on per capita income of Sub-Saharan Africa (SSA) for the period of 2006–2015 using a panel data of 40 countries. We have employed the robust two-step system GMM. Results showed that growth in mobile phone penetration has contributed significantly to the GDP per capita of the region after controlling for a number of other variables. A 10% increase in mobile phone penetration results in a 1.2% change in GDP per capita. Therefore, improving access to mobile phones will play a critical role in reducing the poverty level of the region through raising the per capita income of the population.However, the Internet has not contributed to the per capita GDP during the study period. The insignificant impact of the Internet could be due to low penetration of the technology, low ICT skill of Internet users, lack of or insufficient local content on the global network, and the relatively immature state of the technology in the region. Therefore, governments and other stakeholders should design policies that encourage expansion of the Internet. In addition to improving Internet access, policies which focus on ICT skill development and local content creation should also be designed and implemented.     

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.     

Online job search in the Spanish labor market

Using data from the Spanish survey on equipment and use of ICTs in households for the period 2007–2011, we study the decision of Spanish jobseekers to search for a job online, and explore potential differences between unemployed and employed workers. Since only those jobseekers that have accessed the Internet can perform an online job search, we use bivariate probit selection models to correct for potential selection bias. Our results show that Internet Spanish jobseekers tend to be younger, better educated, more Internet-savvy, and live in urban areas compared to those that only use traditional search channels. However, we find that employment-to-employment and unemployment-to-employment transitions differ by gender, nationality, household income, and time aggregate factors. We find evidence of a digital divide in adoption and usage by age and educational attainment. These findings suggest that policy makers and human resources managers should take into account these disparities in Internet usage to guide their public programs and recruiting strategies.     

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.     

Internet use and job search

Regression analysis augmented with propensity score methods is used to estimate the effect of Internet use on job search. The formal distinction between the unemployed and the discouraged is exploited, where both desire employment but the latter has ceased active job search. Results indicate broadband use at home or at public locations reduces the probability that the unemployed cease job search by over 50% relative to unemployed persons who do not use the Internet at all. The results suggest that even public connections (e.g., at libraries) in unserved and underserved areas may produce substantial social benefits.     

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.     

Making gigs work: digital platforms,job quality and worker motivations

Technology has driven new organisations of work and employment relationships, rendering changes that would have been unimaginable just a decade ago. The rise of digital platforms has not only enabled new forms of work activity but also transformed the way workers find new opportunities. This development, referred to as gig work, is distinct from traditional employment in that it is mediated through online platforms. While we can somewhat objectively designate traditional job characteristics as ‘good’ or ‘bad’, designating gig work itself as ‘good’ or ‘bad’ overlooks the fact that workers are inclined to evaluate the quality of their jobs according to their own individual needs, priorities, backgrounds and other circumstances—even if those jobs are objectively the same. Unlike previous scholarship on gig work, which has viewed job quality largely from a platform-focused perspective, this article takes a worker-centric approach and provides a typology of gig workers. The typology demarcates how gig work is used and indicates key attributes that differentiate how workers approach such jobs. Moreover, the typology reveals heterogeneity in gig workers’ motivations, characteristics and intentions. Consequently, platforms with ‘bad’ job quality characteristics can still offer work that some workers will see as ‘good’ and vice versa.     

How Workers Fare When Employers Innovate

Complementing existing work on firm organizational structure and productivity, this article examines the impact of organizational change on workers. We find evidence that employers do appear to compensate at least some of their workers for engaging in high-performance workplace practices. We also find a significant association between high-performance workplace practices and increased wage inequality. Finally, we examine the relationship between organizational structure and employment changes and find that some practices, such as self-managed teams, are associated with greater employment reductions, whereas other practices, such as the percentage of workers involved in job rotation, are associated with lower employment reductions.     

Demand for telecommunication services in developing countries

Living standards and economic growth in developing countries are invariably linked to the availability and use of telecom services. Effective policy decisions require the best estimates of the drivers of these services. In this paper, telecommunications demand is estimated in models for residential mainline and mobile telephone service for developing countries for the period 1996–2003. The paper tests for cross-price effects between mainline and mobile service and its findings have important policy implications. It finds residential monthly price elasticity to be insignificant for developing countries, but the connection elasticity is larger than generally found in the literature. Mobile monthly price elasticities are very large. A new and important empirical finding is that although wireline phones are substitutes in the mobile market, the contrary is not true—mobile phones are not substitutes in the wireline market, and in fact may be considered complements. This lack of symmetry has important implications for properly defining telecom markets. Universal service subsidies and competitive market initiatives should be reevaluated in light of the paper's elasticity estimates. Increased competition, income growth and enhanced education may be the ultimate universal service promoters.     

An estimate of the average cumulative royalty yield in the world mobile phone industry: Theory,measurement and results

An influential literature argues that dispersed patent ownership may lead to royalty stacking and excessive running royalties, thus increasing the long-run marginal cost of manufacturing phones and their prices. One set of estimates claims that the royalty stack is on the order of 20–40 percent of the value of the average phone. In order to assess this claim, we estimate the average cumulative royalty yield—the sum total of patent royalty payments earned by licensors, divided by the total value of mobile phones shipped— in the world mobile phone industry between 2007 and 2016.We “follow the money” and identify, with varying accuracy, 39 potential licensors in the smartphone value chain. We find that, of these, only 29 charged royalties in 2016, running from a low of $1.6 million to a high of $7.7 billion, summing to $14.2 billion in total, which compares with $425.1 billion in mobile phone sales. The average cumulative royalty yield in 2016 was 3.3 percent or $7.20 per phone. If we restrict this only to smartphones, the result would be $9.60 per phone, roughly 3.4 percent of the average selling price. A sensitivity analysis shows that even under a very restrictive set of assumptions, the average cumulative royalty yield on a smartphone would not exceed 5.6 percent.     

Technology,education, and economic growth in Sub-Saharan Africa

This study examines whether telecommunications infrastructure promotes economic growth in countries with better access to education compared to those with less access. Using a panel of 45 Sub-Saharan African countries from 1993 to 2015, the results using the fixed-effects, two-step feasible efficient generalized method of moments estimator indicate that in countries with better access to education, the Internet contributes to economic growth, while mobile phones do not seem to do so. These results suggest that while education is regarded as pivotal for the Internet, it seems to be irrelevant for mobile phone usage.     

The tribal digital divide: Extent and Explanations

This paper documents home Internet access, types of Internet access, connection speeds, and prices for basic home Internet in tribal areas of the United States. We find that the share of households with Internet access is 21 percentage points lower in tribal areas than in neighboring non-tribal areas. When compared to these non-tribal areas, download speeds, whether measured using fixed or mobile broadband networks, are approximately 75% slower in tribal areas, while the lowest price for basic Internet services in tribal areas is 11% higher. Regression techniques reveal that traditional cost factors such as terrain and population density fully explain the price gap but account for only a fraction of the tribal differences in Internet access and connection speeds. Income differences are strong predictors of Internet access but do not affect connection speeds. A sizable amount of the variation in the access and home connection gap between tribal and non-tribal is left unexplained. We conclude with a discussion of how federal broadband programs have penetrated Indian Country, how tribal-specific factors are related to the variation in Internet access within Indian Country, and the potential policy implications of our findings.     

Sustainability of mobile IT sector in industrially developing countries by supporting repairability

This article aims to provide a design intervention to support the repairability of mobile phones and, in turn, promote sustainability. Typically, mobile phones are designed with a view towards obsolescence for users in industrially developed countries, as the expected repair in these circumstances is minimal. In contrast, in developing countries, such as India, these phones are constantly repaired and are owned several times by different people before their final demise. Therefore, to support repairability, a field study based in Mumbai, India, was conducted to understand the cognitive basis of repair. The results were further analyzed using a cognitive work analysis framework that provides insight into the possibilities for informational requirements for design. The findings indicate that small-scale repair shops (3–4 repairmen) and the hole-in-the-wall shops (1 repairman) can benefit from the intervention in terms of informational support for the repair activity. If the cognitive dimension of repair is supported for these low-cost repair shops, we can expect an increase in the capability and efficacy of the repairmen, resulting in fewer phones ending up as e-waste. Thus, due to its low cost, informational diagrams that support the repair activity can be incorporated by the manufacturer without any radical changes in existing proprietary technology, resulting in the possibility for the long-term growth of the repair ecology in a country such as India.
