Digital Connectivity In Sub Saharan Africa A Comparative Perspective

Higher digital connectivity is expected to bring opportunities to leapfrog development in sub-Saharan Africa (SSA). Experience within the region demonstrates that if there is an adequate digital infrastructure and a supportive business environment, new forms of business spring up and create jobs for the educated as well as the less educated. The paper first confirms the global digital divide through the unsupervised machine learning clustering K-means algorithm. Next, it derives a composite digital connectivity index, in the spirit of De Muro-Mazziotta-Pareto, for about 190 economies. Descriptive analysis shows that majority of SSA countries lag in digital connectivity, specifically in infrastructure, internet usage, and knowledge. Finally, using fractional logit regressions we document that better business enabling and regulatory environment, financial access, and urbanization are associated with higher digital connectivity.

Digital connectivity, including through the modern cellular network technologies, is expected to play a key role for the Future of Work in sub-Saharan Africa (SSA). We estimate the cost of introducing a full-scale 4G network by 2025 in SSA and an operable 5G network by 2040. We adapt the costing model of Lombardo (2019) by accounting for the significant demographic transformation and rapid urbanization in SSA. We use the WorldPop and GADM databases and the UN’s medium-variant population projections to project the population densities at the highest level of administrative division for each SSA country in 2025 and 2040. For full 4G connectivity, the required capital and operational costs stands approximately at US$14 billion by 2025 and for 5G connectivity, costs amount to US$57 billion in 2040, conditional on having the 4G in place by 2025. These costs roughly translate to 8.4 percent of annual subscriber income, on a median basis, by 2025 for 4G and 4.9 percent of subscriber income by 2040 for 5G. Having the infrastructure in place is not sufficient to bridge the mobile Digital Divide. In addition, policies are needed to address affordability and knowledge gaps.

Africa’s Development Dynamics uses lessons learned in the continent’s five regions – Central, East, North, Southern and West Africa – to develop policy recommendations and share good practices. Drawing on the most recent statistics, this analysis of development dynamics attempts to help African leaders reach the targets of the African Union’s Agenda 2063 at all levels: continental, regional, national and local.

Despite issues associated with the digital divide, mobile telephony is growing on the continent and the rise of smartphones has given citizens easy access to social networking sites. But the digital divide, which mostly reflects on one's race, gender, socioeconomic status or geographical location, stands in the way of digital progress. What opportunities are available to tame digital disparities? How are different societies in Africa handling digital problems? What innovative methods are being used to provide citizens with access to critical information that can help improve their lives? Experiences from various locations in several sub-Saharan African countries have been carefully selected in this collection with the aim of providing an updated account on the digital divide and its impact in Africa.

Using cross-country data, this note explores the potential impact of selected digital technologies on tax collection and compliance. The analysis makes use of multi-dimensional International Survey on Revenue Administration, Tax Administration Diagnostic Assessment Tool, and Revenue Administration-Gap Analysis Program (RA-GAP) data with results indicating that digital technologies could help enhance tax collection, but with effects that vary by the type of specific digital service or tools introduced. While the results demonstrate a strong association between digital tax administration operations and improved performance outcomes, the realization of revenue gains is heavily contingent on accompanying policy, legislative, and administrative reforms, as well as the availability of adequate digital connectivity and capable tax administration staff. The cross-country approach provides reasonable upper-bound estimates on revenue gains, which, however, need to be carefully validated with country-specific case studies. The note reviews single country case studies from selected micro-economic literature that complement the cross-country results and reveal key enabling factors necessary to reap and sustain the benefits of new digital investments.
