Abstract
This study empirically assesses the effects of formal institutions on ICT adoption in 49 African countries over the years 2000–2012. It deploys 2SLS and FE regression models (a) to estimate the determinants of ICT adoption and (b) to trace how ICT adoption affects inclusive development. The results show that formal institutions affect ICT adoption in this group of countries, with government effectiveness having the largest positive effects and regulations the largest negative effects. However, while formal institutions generally affect ICT adoption positively, population and economic growth tend to constrain ICT adoption more in low-income countries than middle-income countries. The results further demonstrate that the effects of ICT adoption on development are comparable to those of domestic credit and foreign direct investment. Ceteris paribus, one may conclude that external factors like foreign aid are more limiting to inclusive development than internal factors. This suggests that developing countries, African countries in this specific case, can enhance their ICT adoption for development by improving formal institutions and by strengthening domestic determinants of ICT adoption. Both represent opportunities for further research.

Notes
- 1.
Wherever the term “adoption” appears in this study, it should be read and understood as “adoption with diffusion.” Under conditions of rapid technological change, an ICT that is just adopted may never be diffused, and for this reason we stress ICTs that have been adopted and penetrating the economy as catalysts for inclusive development.

1.1 Supplement 1: The Theory Behind the Model
We assume a basic Schumpeterian model in which the economic activity is described as:
where, Y i is the real GDP of the ith economy, in Schumpeter’s terminology A i (technology, including ICT) and S i (socioeconomic setting, including institutions) are “evolution components”, X i are “growth components”, including conventional factors of production, and all variables are dated ([53]; cf. [54, 55]). Central to growth among X i is capital accumulation, which over time depends on investment (I) equal to savings in a steady state. Savings come from profit (π) made possible by technological change and the socioeconomic setting surrounding it. The evolution of the socioeconomic environment is a function of resources, technology, and level of development, i.e.:
A Schumpeterian technological change is discontinuous due to five initiators: (a) introduction of new ideas, requiring technological know-how; (b) introduction of new production techniques for which funds (credit) are essential; (c) discovery of new sources of supply; (d) discovery of new markets; and (e) change in the structure and organization of the industry involved. Thus, in dynamic form Eq. (10.1) is characterized by the Schumpeter-Kondratiev waves (cycles), such that A i over time is sinusoid, i.e.:
and \( \partial A/\partial t={A}_0\left(\varphi - b\right) \sin\ \left( bt+\psi \right) \exp\ \left(\varphi t+ \cos\ \left( bt+\psi \right)\right), \) which is consistent with [15] Eqs. (10.3 and 10.4 (p. 6)), but we do not pursue this line of thought further. Instead, from Eq. (10.1) we solve for A i as:
Dividing both sides of Eq. (10.3) Equation 10.5 by some specific \( {X}_i={X}_i^{\ast } \) such as population or labor (worker), and taking the natural logs on both sides, we get a per capita (per labor, per worker, per head) indicator of adoption with diffusion as follows:
where \( \begin{array}{l}\dot{\mathrm{A}}= \log \left(\frac{A_i}{X_i^{\ast }}\right)= IC{T}_i;{\alpha}_i^{\ast }=\frac{1}{\alpha};{\dot{y}}_i=\mathrm{economic}\;\mathrm{growth};\hfill \\ {}{\beta}_i^{\ast }=\frac{\beta_i}{\alpha_i};{\dot{s}}_i= \log \left(\frac{S_i}{X_i^{\ast }}\right)=\mathrm{economic}\;\mathrm{setting}\ \left(\mathrm{governance}\right);\hfill \\ {}{\gamma}_i^{\ast }=\frac{\gamma_i}{\alpha_i};{\dot{x}}_i=\frac{X_i}{X_i^{\ast }}=\mathrm{primary}\kern0.75em and\kern0.75em \mathrm{other}\kern0.75em \mathrm{drivers};\kern0.5em \hfill \\ {} and\kern0.5em {\mu}_i=\mathrm{the}\kern0.5em \mathrm{random}\kern0.5em \mathrm{classical}\kern0.5em \mathrm{error}\kern0.5em \mathrm{term}.\hfill \end{array} \)
This all shows that in the main document, the ICT equation is the equivalent of 10.(6) Eq. (10.4) above, and the development equation is Eq. (10.1) 10.3.
1.2 Supplement 2: A Note on Country Classification by Income Level
The World Bank classifies countries as developing if they are low income ($0–1,045 per capita) and lower middle income ($1,046–4,125 per capita). Countries with upper middle incomes ($4,126–12, 735 per capita) and high incomes ($12,736 or higher) are classified as being developed. The classification is arbitrary. No particular line of reasoning is given for why the cutoff point between “developed” and “developing” is set at $12,735. There is no reason to believe that a country just below the cutoff line cannot be more “developed” than a country just above it. For instance, Equatorial Guinea has a higher average income level than both China and South Africa, but its industrial base and technological structure are miles far behind. This is one of the reasons we modified the World Bank and grouped African countries into two groups: low-income group consisting of 28 countries, and middle-income group made up of 21 countries. This reclassification is consistent with our understanding of both ICT and development in these countries.
