Existing studies have shown that income inequality remains a core determinant of population health. These findings are in line with the Income Inequality-Health Hypothesis (IIHH). However, this assertion remains unclear for Sub-Saharan Africa (SSA), despite the rising trend of income disparity in the region and the vastness of the studies that tested the validity of the IIHH. This inferential study, therefore, examines the effect of income inequality on health for 31 Sub-Saharan African countries from 1995 to 2015 using life expectancy at birth, infant mortality rate, and under-five mortality rate as indicators of population health, as well as the Gini index as a measurement of income inequality. The study employed the Generalized Method of Moments (GMM). We infer that income inequality contributes significantly to poor population health in Sub-Saharan Africa, thereby affirming the validity of the Income Inequality-Health Hypothesis for the region.

Aims: To analyze financial inclusion as a channel to alleviate inequality in order to provide insight into the edifice of inequality reduction. Study Design:  Dynamic panel study. Place and Duration of Study: Sub-Saharan African countries over the period 2004-2018. Methodology: Using the generalized method of moments (GMM) on a sample of 27 Sub-Saharan African countries. Results: The results show that the estimated financial inclusion index has a negative effect on income inequality. Therefore, the depth of commercial bank branches and the effective use of bank accounts reduce income inequality. Conclusion: Increase financial inclusion as well as the development of financial infrastructure and the provision of specific low-cost services tailored to low-income households.

We advance a set of population-level indicators that quantify the prevalence of mothers who have ever experienced an infant, under 5-y-old child, or any-age child die. The maternal cumulative prevalence of infant mortality (mIM), the maternal cumulative prevalence of under 5 mortality (mU5M), and the maternal cumulative prevalence of offspring mortality (mOM) bring theoretical and practical value to a variety of disciplines. Here we introduce maternal cumulative prevalence measures of mortality for multiple age groups of mothers in 20 sub-Saharan African countries with Demographic and Health Surveys data spanning more than two decades. The exercise demonstrates the persistently high prevalence of African mothers who have ever experienced a child die. In some African countries, more than one-half of 45- to 49-y-old mothers have experienced the death of a child under age 5, and nearly two-thirds have experienced the death of any child, irrespective of age. Fewer young mothers have experienced a child die, yet in many countries, up to one-third have. Our results show that the mIM and mU5M can follow distinct trajectories from the infant mortality rate (IMR) and under 5 mortality rate (U5MR), offering an experiential view of mortality decline that annualized measures conceal. These measures can be adapted to quantify the prevalence of recurrent offspring mortality (mROM) and calculated for subgroups to identify within-country inequality in the mortality burden. These indicators can be used to improve current understandings of mortality change, bereavement as a public health threat, and population dynamics.

This study evaluates the relevance of inclusive financial access in moderating the effect of income inequality on economic growth in 48 countries in Sub-Saharan Africa (SSA) for the period 1995 to 2017. The findings using the Generalised Method of Moments (sys-GMM) technique show that inclusive financial access contributes to reducing inequality in the short run, contrary to the Kuznets curve. The result reveals a negative effect of financial access on the relationship between income inequality and economic growth. There is a positive net effect of inclusive financial access in moderating the impact of income inequality on economic growth. Given the need to achieve the Sustainable Development Targets in the sub-region, policymakers and other stakeholders of the economy must design policies and programmes that would enhance access to financial services as an essential mechanism to reduce income disparity and enhance sustainable economic growth.

Infant mortality is a major health problem in developing countries. It is an important indicator of a country's public health as it goes hand in hand with socio-economic conditions and many others. Public health spending has been committed to reducing this scourge. This has led to the completion of numerous studies which have yielded mixed results. The main objective of this study is to test the effect of public health expenditure (% GDP) on the infant mortality rate, taking into account the role that institutional quality can play. To achieve this, we use two approaches which are the autoregressive vector panel model with exogenous variables (PVAR (X)) and the smooth threshold regression model (PSTR) on annual data covering the period 2002-2016 and covering 37 African countries. Sub-Saharan. Our main results through the PVAR (X) reveal that in the absence of institutional variables, public health expenditure has a negative and significant effect on the infant mortality rate, whereas, in the presence of the various institutional variables, this effect is still negative but is no longer significant. Our results show that the presence of institutions halves the weight of public health expenditure in explaining the infant mortality rate. In addition, our results show through the PSTR that there is a certain level of institutional qualities that these countries must achieve for public health expenditure to positively affect infant mortality rates. These thresholds oscillate for all the institutional variables around 7%. Taking institutional variables into account will help reduce infant mortality in Sub-Saharan African countries.

PurposeThe purpose of this study is to examine the impact of economic freedom on four key health indicators (namely, life expectancy, infant mortality rate, under-five mortality rate and neonatal mortality rate) by using a panel dataset of 34 sub-Saharan African countries from 2005 to 2016.Design/methodology/approachThe study obtains data from the World Development Indicators (WDI) of the World Bank and the Fraser Institute. It uses fixed effects regression to estimate the effect of economic freedom on health outcomes and attempts to resolve the endogeneity problems by using two-stage least squares regression (2SLS).FindingsThe results indicate a favourable impact of economic freedom on health outcomes. That is, higher levels of economic freedom reduce mortality rates and increase life expectancy in sub-Saharan Africa. All areas of economic freedom, except government size, have a significant and positive effect on health outcomes.Research limitations/implicationsThis study analyses the effect of economic freedom on health at a broad level. Country-specific studies at a disaggregated level may provide additional information about the impact of economic freedom on health outcomes. Also, this study does not control for some important variables such as education, income inequality and foreign aid due to data constraints.Practical implicationsThe findings suggest that sub-Saharan African countries should focus on enhancing the quality of economic institutions to improve their health outcomes. This may include policy reforms that support a robust legal system, protect property rights, promote free trade and stabilise the macroeconomic environment. In addition, policies that raise urbanisation, increase immunisation and lower the incidence of HIV are likely to produce a substantial improvement in health outcomes.Originality/valueExtant economic freedom-health literature does not focus on endogeneity problems. This study uses instrumental variables regression to deal with endogeneity. Also, this is one of the first attempts to empirically investigate the relationship between economic freedom and health in the case of sub-Saharan Africa.

Abstract The study examines the impacts of entrepreneurship on income inequality in a panel of 29 Sub-Saharan African countries spanning from 2004 to 2020. The paper employs a dynamic heterogeneous panel approach to differentiate between long-run and short-run impacts of entrepreneurship on income inequality. The findings establish a robust and direct nexus between entrepreneurial activities and income disparity. The results of the two entrepreneurial indicators are stable. Besides, the coefficient of the human capital is positive in the regression and statistically significant at a 5 percent significance level. The proxies for macroeconomic factors exhibit diverse signs and impact, which suggest a policy stimulus aimed at refining macroeconomic situations and also ignite prospects for households to increase their incomes.

Purpose: This research looked into debate on the possible impact of human capital on economic growth in Sub-Saharan Africa (SSA) and considers two alternative measures of human capital: health and education. Methodology: The research used a dynamic model based on the system generalized method of moments (SGMM) and analysed a balanced panel data covering 35 countries from 1986–2018. The research used Microsoft excel to record all the data gotten from the world indicator data base from world bank, penn world table data base and CANA database. The analysis was presented in a tabular form. Findings: This study found that human capital has an overall positive and statistically significant impact on economic growth in the SSA region, although, democracy has a negative and statistically significant impact on economic growth in the region. This finding shows the importance of both measures of human capital and aligns with the argument in the literature that neither education nor health is a perfect substitute for the other as a measure of human capital. Unique contribution to theory, practice and policy:Generally, the finding emphasised that both education and health measures of human capital are important, and that policymakers must consider the level of economic development while formulating policies that can enhance the impact of human capital on economic growth in the Sub-Saharan Africa region.

This paper examines the relationship between globalization and income inequality in Sub-Saharan Africa (SSA). Globalization is here measured using trade variables like the openness rate (TO), financial variables including FDI while income inequality is measured by the GINI coefficient. This was achieved by using data from 26 countries over the period 2005-2014, using the System Generalized Method of Moments (SGMM) estimator to obtain results from the African context. The results suggested that trade openness exerted an equalizing effect while financial globalization through FDI has been the critical factor driving inequality in the SSA since 2005. The results also showed that outside of FDI, corruption contributes greatly to widening inequality by about 3%. The effect of the other control variables was all together insignificant. The prevailing economic status as portrayed following on the back of the 2008 financial crisis has led to an increase in inequalities in SSA countries. These results are robust to the using of the KOF Globalization index. Through this research, governments and policymakers have to introduce robust and appropriate policies and interventions in their drive for economic growth to decisively deal with corruption and so direct FDI to economically sound targeted priority programs.

AbstractSub-Saharan Africa (SSA) ranks as the second most unequal region globally (in terms of income distribution), harboring 10 of the 19 most unequal countries in the world. This paper explores the channels through which income inequality exerts its effects on economic growth in SSA. The study spans the period 1995–2015, focusing on 31 SSA countries. Findings from the two-step system generalized method of moments suggest that income inequality exerts a significant positive effect on economic growth via the saving transmission channel, while it has a statistically significant negative effect on economic growth in the region through the channels of fertility, credit market imperfection, and fiscal policy.
