    Health expenditure, health outcomes and productivity in sub-Saharan Africa: sustainable thresholds, moderation and forecasting.
    (2023) Adegoke, Yetunde Oluranti.; George, Gavin Lloyd.; Mbonigaba, Josue.
    SSA is known to be confronting distinctive health problems and growth challenges, thereby, inadequate health expenditure, poor health outcomes and their implications for productivity require investigation. This situation persists despite evidence-related policy produced in the past, suggesting the need to investigate further the nature of the relationship between interrelated variables. This study aims to investigate the nonlinear effect of PHE on health outcomes and the moderating role of education on health outcomes, forecast the performance of different PHE scenarios in achieving the 2030 Sustainable Development Goals (SDGs), examine the effect of PHE and health outcomes on TFP and assess the moderating role of education in the relationship between PHE and TFP. The study utilizes various techniques including Panel spatial correlation consistent-ordinary least squares (PSCC-OLS and PSCC-FE) for Objective One, Feasible quasi-generalized least squares (FQGLS) for Objective Two. Fixed and random models, panel two-stage least squares (P2SLS), and panel threshold regression for Objective Three. System panel generalized method of moments (GMM) for Objective four. This study concludes a nonlinear relationship between PHE and health outcomes exists. Furthermore, the interaction of PHE and education would improve health outcomes. Second, an overall increase in PHE by 30% would achieve the SDG target of 70 maternal deaths in only Botswana, Namibia and South Africa. In addition, about 60% of the countries in SSA might be able to achieve the SDG target for child mortality by the year 2030. Third, including PHE and health outcomes into the TFP framework would guarantee a further increase in TFP growth in SSA, and a threshold level of PHE above 3.5% of the GNP could achieve better health outcomes and a further increase in TFP growth in SSA. Fourth, the interactive impact of PHE and education might cause an improvement in TFP in SSA. The study pioneers the investigation of nonlinear, threshold, moderating, forecasting and collaborative effect of PHE, the information is essential for optimizing, redistributing and utilization of resources, specifically, a minimum of 38 dollars per person will achieve better health and productivity in SSA.

    Health inequality and healthcare policies’ efficacy across areas with different deprivation levels within South Africa.
    (2024) Dlamini , Msawenkosi Milton.; Mbonigaba , Josue.
    Despite South Africa's efforts to reduce socio-economic inequalities since 1994 through policies like the Reconstruction and Development Programme and the Broad-Based Black Economic Empowerment Act, significant disparities remain. While these policies aimed to improve access to services and provide economic opportunities for marginalised communities, their impact has been limited. As a result, health disparities persist, challenging the effectiveness of existing health policies. This thesis seeks to fill a research gap by assessing health inequalities and the efficacy of healthcare policies across regions with varying levels of deprivation in South Africa. It is structured around four interconnected analyses. The first analysis investigates the impact of localised deprivation on adult health across different areas (traditional authority, formal rural, and formal and informal urban regions) using ordered probit models and data from the National Income Dynamics Study (NIDS). The findings reveal significant health disparities, especially in informal urban areas, where increased deprivation is strongly correlated with poor self-rated health. This highlights the need for targeted health interventions in these regions. The second analysis explores socio-economic inequalities in chronic illnesses and disabilities among children utilising concentration indices, Oaxaca-Blinder Decomposition, and NIDS data from the 2008 and 2017 waves. The results show stark disparities, with children from wealthier households in formal urban areas benefiting from better health outcomes, while poorer children in informal urban areas are disadvantaged. The third analysis examines diabetes prevalence among South African adults using standardised concentration indices, decomposition techniques and NIDS data. It uncovers varying socio-economic disparities across regions, with some areas showing reduced inequalities while others show increasing disparities. The final analysis looks at the relationship between public health expenditure and health outcomes from 2005 to 2019 across South African provinces employing two-way fixed effects panel models data from multiple sources. It finds that higher per capita health spending is paradoxically associated with lower life expectancy, indicating inefficiencies in resource allocation. Overall, the study underscores the need for tailored, region-specific healthcare policies to address the diverse challenges and reduce health inequalities across South Africa.
