Sustainable governance, digital transformation, and environmental sustainability in Africa’s Decade of Action
Does Knowledge Empower Climate Action? The Moderating Role of Governance in the Education–Carbon Neutrality Nexus
This study explores how governance quality moderates the impact of education on carbon emissions in 119 developing countries from 2003 to 2021. Using a two‐step System GMM approach, it examines the roles of primary, secondary, and tertiary education alongside six governance indicators. Results show that strong governance—especially regulatory quality and rule of law—amplifies the emissions‐reducing effects of primary and tertiary education. Secon…
Do Public‐Private Partnership Investments Influence Poverty in Southern African Economies? A Panel VAR Approach
As Southern African economies continue to struggle with achieving Sustainable Development Goal 1 (eradicating poverty), there is an increasing need for strong collaboration between public and private sectors to accomplish this goal, as the public sector cannot achieve it alone. Based on this, this study examines the influence of public‐private partnership investments (PPPI) on poverty and its severity in Southern African economies from 2000 to 20…
Competition Policy and Achieving Sustainable Development Goal 1 (No Poverty)
South Africa faces persistently high poverty and inequality alongside a highly concentrated economic structure, raising questions about whether merger control, especially public‐interest provisions, can contribute to poverty reduction. However, empirical evidence directly linking merger adjudication outcomes to poverty remains limited. This study examines how merger adjudications influence poverty incidence and poverty depth in South Africa, focu…
The Nexus Between ICT Diffusion, Financial Development, Industrialization and Economic Growth
This study examines the nexus between ICT diffusion, financial development, industrialization, and economic growth using a novel panel VAR approach in the generalized method of moments (GMM) estimation. Different proxies were used to measure the aforementioned variables, diverging from the commonly used measures in prior literature. Based on panel data covering 45 countries from 2000 to 2018, the empirical results suggest that there is bidirectio…
Artificial intelligence (AI)-poverty-economic growth nexus in selected BRICS-Plus countries
The BRICS nations (Brazil, Russia, India, China, and South Africa) aim to achieve Sustainable Development Goal (SDG) 1 (poverty eradication) and SDG 8 (sustainable economic growth), yet the moderating role of governance in artificial intelligence (AI)-poverty-growth nexus remains underexplored. Therefore, this study investigates the AI-poverty-economic growth nexus in selected BRICS-Plus countries (2012–2023), with governance as a moderating vari…
Leveraging the potential of artificial intelligence (AI) in exploring the interplay among tax revenue, institutional quality, and economic growth in the G-7 countries
Due to G-7 countries' commitment to sustaining United Nations Sustainable Development Goal 8, which focuses on sustainable economic growth, there is a need to investigate the impact of tax revenue and institutional quality on economic growth, considering the role of artificial intelligence (AI) in the G-7 countries from 2012 to 2022. Cross-Sectional Augmented Autoregressive Distributed Lag (CS-ARDL) technique is used to analyze the data. The stud…
The impact of artificial intelligence (AI) on maternal mortality
BACKGROUND: This study examines the impact of Artificial Intelligence (AI) on maternal mortality in alignment with Sustainable Development Goal (SDG) 3.1, which aims to reduce maternal mortality to below 70 per 100,000 live births by 2030. Despite advancements, maternal mortality remains disproportionately high in developing countries due to weaker healthcare infrastructure. METHODS: Using panel data from 70 countries (1990-2022), sourced from WH…
Fiscal Autonomy and the Path to Sustainable Local Economic Development
Despite fiscal reforms aimed at achieving Sustainable Development Goal Target 17.1—strengthening domestic resource mobilization for development—the impact of fiscal autonomy on local economic development (LED) in South Africa remains underexplored. Therefore, this study examines the impact of fiscal autonomy across 248 municipalities from 2009 to 2023, employing a range of advanced econometric methods. The results highlight a complex relationship…
Trade openness, economic growth and economic development nexus in South Africa
This research analyses the interplay between trade liberalisation, economic growth, and economic development in South Africa. The research focuses on two distinct periods, pre-BRICS (1991 to 2010) and post-BRICS (2011 to 2021) and aims to assess economic growth and development trajectories which are intertwined with liberalisation. A Vector Error Correction Model (VECM) is used to account for potential cointegration among the variables. The study…
The impact of artificial intelligence (AI) investment on human well-being in G-7 countries
This study examines the AI investment (AII)-human well-being (HWBG) nexus contingent on governance indicators/dimensions within G-7 nations from 2012 to 2022 using the Cross-Sectional Augmented Autoregressive Distributed Lag (CS-ARDL) technique. Based on these results, policymakers should prioritize integrating AII into governance to boost HWBG in the short- and long-term. However, caution is needed when considering AII's interaction with institu…
The impact of freight infrastructure investment on employment in South Africa
The purpose of the current study is to assess the economic impact of Transnet’s infrastructure investment on employment in the South African economy. We used data from Transnet, the South African Reserve Bank and Quantec dating from 1992 to 2016. Hausman–Taylor, pooled OLS, random effects and dynamic fixed effect models are used to validate the results. The estimated results reveal that capital investment in rail transportation creates employment…
Convergence or Divergence Patterns in Global Defence Spending
This study re-examines the international convergence in defence spending for 125 countries spanning 1985–2018. We employ the approach of Phillips and Sul, which tests for the existence of convergence clubs and the modelling of different transition paths to convergence. Our findings suggest no overall defence spending convergence at the world, income groups (except the low-income countries) and regional levels. However, we identify two convergence…
Military expenditure, security outcome and industrialisation in Africa
This study examines the cause-and-effect relationship between military expenditure, security outcome and industrialisation for a panel of 35 African countries spanning from 1990 to 2015. We employed: (i) the Pairwise Dumitrescu-Hurlin panel causality test; and (ii) the newly developed panel VAR in generalised method of moment (GMM) estimation approach was applied to determine what magnitude can future disparities in industrialisation be explained…
An investigation of security outcome convergence and the dynamics of their influencing factors in Africa
This study explores the drivers of security outcome convergence for 51 African countries spanning the period from 2000 to 2018. Phillips and Sul convergence club and system generalised method of moments (SGMM) estimation techniques were applied. The main findings suggest security outcome convergence, and this implies that African countries are characterised by similar factors (economic, developmental, geographic and governance) which in turn dete…

Military Expenditure and Security Outcome Convergence in Africa
This study investigates the degree of convergence in military expenditure and security outcomes for a panel of 34 African countries spanning the period 1995 to 2015. We apply the Phillips and Sul methodology. Overall, the results reveal no evidence among African countries to suggest that military expenditure and security outcomes converge. The results of the analysis show that there exist: (i) three convergence clubs for military expenditure; (ii…
Security as an outcome for promoting economic prosperity in the regional economic communities of Africa
This study investigates the impact of security outcomes on economic prosperity in Africa and its Regional Economic Communities (RECs) using a balanced panel data of 35 African countries and eight RECs for the period 1990–2015. Economic prosperity was measured with real GDP per capita as the proxy while security outcomes was computed from security effectiveness and legitimacy by using principal component analysis. This study employs a panel causal…
Military expenditure and economic growth
This study investigates the causal relationship between military expenditure and economic growth by using a balanced panel of 35 African countries spanning 1990 to 2015. It uses the more recently developed bivariate heterogeneous panel causality, GMM and SGMM estimation techniques. The country-by-country causality results reveal:(i) no causal relationship between military expenditure and growth in seven countries; (ii) unidirectional causality fr…
