Item Public sector transparency and sustainable development: A focus on Sub-Saharan Africa(Journal of Public Affairs (An International Journal) Volume24, Issue1 (Wiley), 2023-06-19) Erin Olayinka; Adegboye Alex; Uwuigbe UwalomwaItem Tax and sustainable development in sub-Saharan Africa(WIDER Working Paper 2023/54, 2023-04) Adegboye Alex; Abrams M. L.Abstract: This paper establishes how accountability quality might mediate the effect of tax revenue on sustainable development in 41 sub-Saharan African countries for the period 1990–2019. The empirical evidence is based on three empirical strategies: generalized method of moments, instrumental variable Tobit, and quantile regressions. The following findings are revealed. First, accountability dynamics influence tax revenue in ways that have favourable net effects on sustainable development. Second, the conditional impacts between accountability dynamics and tax revenues are constantly negative, even though the demonstrated net effects are compatible with the paper’s theoretical predictions. Third, the net consequences are decomposed to establish thresholds for further policy. Thresholds are points where there are no net effects and where further intensifying accountability dynamics would produce adverse net impacts. At the stated thresholds, further policy actions must be complemented with accountability dynamics in order to modulate tax revenues for strong sustainability. We conclude that policy makers in sub-Saharan African nations should coordinate measures that improve accountability in view of other complementary policies, because accountability serves as a ‘force multiplier’ enhancing the absorptive capacity of tax mobilization, which in turn promotes strong sustainability.Item Liquidity Management on The Performance of Listed Insurance Companies in Nigeria*(Communications of International Proceedings (IBIMA Publishing), 2022) Oluwatobi Fasheyitan David; Ikpefan Ochei Ailemen; Adegboye AlexA business's viability and success is largely influenced by its liquidity management style and control. This is because either inadequate or excess liquidity may impair the smooth operation of the business. This apparent problem has sparked considerable interest in issues of the management of liquidity in the context of significant financial outlays. However, diagnosis has been scarce in the insurance industry. Thus, the article's objective is to investigate how liquidity impacts the entire performance that results in financial efficiency. The research is based on a sample of ten insurance companies that were publicly traded on the Nigerian Stock Exchange from 2013 to 2019. Using a random effect panel regression model, this research discovered that liquidity management had a strong negative correlation with financial performance metrics in Nigeria's insurance industry. However, just a single positive coefficient was observed with current ratio affects performance in relation to ROA, while ROE was automatically insignificant when the same variables were used. Additionally, what set this investigation apart was the inclusion of economic factors that had no impact on the research. The study concludes, among other things, that given the volatility or risk level connected with insurance companies' services, it is critical for them to constantly invest in accessible assets regardless of the associated cost of payment or in meeting their commitments.Item The mobile phone technology, gender inclusive education and public accountability in Sub-Saharan Africa(Telecommunications Policy Volume 45, Issue 4,, 2021-05) Asongu A.; Adegboye Alex; Ejemeyovwi Jeremiah O.; Umukoro O. E.This study assesses the relevance of mobile phone technology in complementing gender inclusive education (i.e. primary, secondary and tertiary) to promote public accountability (i.e. involving horizontal, vertical and diagonal accountability dynamics). The study utilizes the generalized method of moments (GMM) technique to establish the empirical evidence based on 48 Sub-Saharan African countries for the period 2005– 2018. The following findings are documented from the linkages between mobile phone technology, inclusive education and public accountability. First, the interactions between mobile phone technology and inclusive education promote public accountability. Second, with regard to net effects, while unexpected negative signs are established, the corresponding positive interactive effects indicate that enhancing the penetration of mobile phone technology beyond some critical thresholds ensures positive net effects. Hence, policy makers should ensure that mobile phone technology penetration exceeds the established thresholds in order for gender inclusive education to positively affect public accountability.Item Technology penetration and human development nexus in middle-income countries: the synergy effect of inclusive resources distribution(Information Technology for Development Volume 28, 2022 - Issue 4 (Published online), 2022) Adegboye Alex; Ojeka Stephen A.; Tolase Olawunmi; Omoremi Oluwatayo; Jude-Okeke YvonneThis paper intends to examine how interactions between equal distribution of resources and the information and communication technology (ICT) influence inclusive human development (inequality-adjusted human development) for 81 countries from middleincome countries within the period 2005–2017. We use a double-censored Tobit regression as it accounts for the dependent variable with a limited range. It exhibits the behavior that is consistent with the method of estimation. We employ the instrumental variable (IV) for the independent variables of interest to deal with simultaneity or reverse causality due to endogeneity. In light of established findings for this study, we conclude that equal distribution of public goods such as technologies could play a critical role in promoting inclusive human development. Supplementary policy repercussions are highlighted.Item Taxing Africa for inclusive human development: the mediating role of governance quality(Journal of Economic and Administrative Sciences Volume 41 Issue 1 (Emerald Publishing), 2025-02-04) Adegboye Alex; Erin Olayinka; Asongu SimplicePurpose Given that the literature on the links between taxation and inclusive human development is ambiguous, it is important to investigate whether the mediating influence of governance in taxation for inclusive development exists. Thus, this study aims to explore the linkages between the governance quality, taxation and inclusive human development (i.e. inequality-adjusted human development index). Design/methodology/approach This study employs the generalized method of moments (GMM) technique to establish the empirical findings on 52 African countries for the period 2010– 2018. Among the existing GMM approaches, this study follows the Roodman approach, an enhancement of the Arellano and Bover techniques, which limits the proliferation of instruments. This study uses the two-step approach, which deals with issues of the heteroscedasticity as against instead the one-step procedure, which solely addresses the homoscedasticity concerns. Findings The following findings are established. First, there is an unconditional positive effect of taxation on inclusive human development. Second, the net effects of taxation on inclusive human development, associated with the interaction of the government revenue with governance quality variables, are positive for the most part. It is then evident that when taxation policies are combined with good governance initiatives, the ultimate impact of inclusive human development is likely to be enhanced. Originality/value This study establishes that, whereas taxation dynamics largely have a favorable incidence in promoting inclusive human development, when such taxation measures are complemented with good governance initiatives, the overall impact of inclusive human development is also likely to be positive. It follows that policies designed to promote political, economic and institutional governance should be implemented in tandem, which policies designed to boost tax performance in the sampled countries. The findings can also be understood from the perspectives that inclusive human development is likely to be boosted when taxation measures are complemented with, (1) the free and fair election and replacement of political leaders (i.e. political governance), (2) the formulation and implementation of inclusive policies for the delivery of public goods (i.e. economic governance) and (3) the respect by citizens and the state of institutions that govern interactions between them (i.e. institutional governance).Item Taxation, democracy, and inequality in Sub-Saharan Africa: Relevant linkages for sustainable development goals(Plitictics and Policy (Wiley)), 2025-06) Adegboye Alex; Adegboye Kofo; Uwuigbe Uwalomwa; Ojeka Stephen A.; Fasanu EyitemiGiven that the linear linkage between taxation and income inequality remains unclear, especially in Sub-Saharan African countries, it is critical to explore how the redistribution channel of the tax system could mitigate income inequality within democratic institutions. Using the instrumental variable approach for robust analysis, this study explores the panel dataset of 42 Sub-Saharan African countries from 1996–2014. The following findings are documented. First, both unconditional linkages between taxation and democracy overwhelmingly reduce income inequality. Second, harnessing democracy with taxation has a net effect that reduces income inequality. Overall, this study establishes that a strong democratic system strengthens the tax system for an income redistribution strategy to enhance income equality. This study is relevant for the achievement of Sustainable Development Goal (SGD) 1 on poverty reduction, SDG 10 on inequality, and SDG 16 on strong institutions.Item Fostering Integrated Governance Quality through Technology Penetration: Thresholds of Democracy in Sub- Saharan Africa(Africa. J Knowl Econ 15, 9142–9173 (Springer Nature), 2024-02) Ejemeyovwi Jeremiah O.; Adegboye Alex; Umukoro O. E.; Asongu Simplice A.In the quest for the attainment of democracy with its fully unleased potential, the role of information and communication technology (ICT) is integral within this current knowledge economy disposition. The study explores the effect of mobile technology penetration on governance quality from the unconditional and marginal effects of mobile phones and diverse democracy indicators. The analysis is carried out by applying the instrumental variables (IV) Tobit regression to the data to examine the relationship among the variables of interest with a view to handling possible endogeneity issues in the empirical model. The study finds that weak democracy is detrimental to the effect of mobile phone penetration on integrated governance quality and that the higher the mobile phone penetration, the lower the weak democracy quality in SSA. The study concludes by recommending efforts and policies to be enacted and implemented such as the enhancement of mobile technology for concise quality governance.Item Financial Inclusion and Information Communication Technology on Tax Performance in Sub-Saharan Africa(International Journal of Professional Business Review Vol. 8, Nº. 12, 2023, 2023) Adeyemo Kingsley Aderemi; Adeyanju Ibukunoluwa Temiloluwa; Ekundayo Gbenga; Adegboye Alex; Ali ShahnawazItem Driving information communication technology for tax revenue mobilization in Sub-Saharan Africa(Telecommunications Policy Volume 46, Issue 7, 2022) Adegboye Alex; Uwuigbe U.; Ojeka Stephen A.; Uwuigbe Olubukunola; Dahunsi Olajide; Adegboye KofoThis study explores whether increasing Information and Technology Communication (ICT) boosts government revenue mobilization for sustainable development in 48 Sub-Saharan African countries from 2004 to 2020. While total tax revenue non-resource as a percentage of GDP and tax revenue as a percentage of GDP are used to proxy for tax revenue mobilization, three ICT measures are used, namely; the telephone penetration rate, the mobile phone penetration rate and internet penetration rate. To perform the analysis, we adopt the Generalized Method of Moments (GMM). The empirical findings are as follows. First, while the calculated net impacts are substantially positive, the corresponding marginal ICT effects utilized for calculating net effects are extremely negative. Second, an extensive study is carried out to determine complementing policy thresholds. These thresholds include: 21.959 (per 100 people) telephone penetration for total income from tax revenue; 16.333 (per 100 people) internet penetration for total income from tax; 21.125 internet penetration (per 100 people) for the income from the tax on non-resource income. This study has policy relevance, and implications as the penetration of the ICT rate can be influenced by policies to mobilize government revenue effectively
