CHAPTER ONE
INTRODUCTION
1.1 Background to the Study
Health expenditure plays a pivotal role in fostering economic growth, particularly in developing economies like Nigeria. The relationship between health investment and economic performance has been extensively explored in the literature, with evidence suggesting that higher health expenditure leads to improved labor productivity, increased life expectancy, and overall economic development (Alhassan et al., 2021; Ogunjimi, 2019). Health is a critical component of human capital, and investments in health-care services—both public and private—contribute significantly to enhancing a nation's workforce by reducing mortality rates and increasing the efficiency of labor (Ibukun, 2021). As a result, countries that allocate substantial resources to health-care tend to experience sustainable economic growth, as a healthy population fosters productivity and innovation (Dritsaki & Dritsaki, 2024).
In Nigeria, health expenditure has remained a subject of concern due to its direct impact on the country's economic performance. Over the years, the Nigerian government has made various attempts to increase budgetary allocations to the health sector, but these efforts have often fallen short of international benchmarks (Adebisi et al., 2020). Despite the African Union's Abuja Declaration of 2001, which recommended that African governments allocate at least 15% of their national budgets to health, Nigeria's health expenditure has consistently remained below this threshold (Edeme & Olisakwe, 2019). The underfunding of the health sector has resulted in a poorly equipped health-care system, inadequate medical infrastructure, and a lack of essential health-care personnel, all of which negatively affect economic productivity and human capital development (Okoye et al., 2019).
The link between health expenditure and economic growth has been extensively studied in different contexts. Empirical evidence suggests that increased public health spending leads to a reduction in mortality rates, longer life expectancy, and higher labor force participation, all of which contribute to economic growth (Murthy et al., 2021). Conversely, inadequate health financing exacerbates disease burdens, reduces workforce efficiency, and increases out-of-pocket health expenses, thereby impeding economic growth (Yang, 2020). Nigeria's health financing system is characterized by a high reliance on out-of-pocket expenditures, which places significant financial strain on households and exacerbates poverty levels (Aziz et al., 2021). The World Health Organization (WHO) has consistently emphasized the importance of universal health coverage (UHC) as a mechanism to promote equitable access to health-care services and drive economic development (Adebisi et al., 2020). However, Nigeria's health-care system remains underfunded, limiting the achievement of UHC and, consequently, economic growth.
At the sub-national level, local governments play a crucial role in health-care service delivery. The Ijebu Ode Local Government Area (LGA) serves as a microcosm of Nigeria's broader health expenditure challenges. The LGA's health-care system is constrained by limited funding, inadequate infrastructure, and insufficient health-care professionals, which negatively affect health outcomes and economic activities within the region (Joshua, 2019). This local perspective provides valuable insights into the broader national debate on health expenditure and economic growth. If properly funded, local health-care systems can significantly contribute to national economic performance by ensuring that a healthy and productive workforce is sustained (Jibir & Aluthge, 2019).
Furthermore, the relationship between health-care spending and economic growth is influenced by environmental and socio-economic factors. Studies have shown that environmental pollution, poor living conditions, and weak governance structures exacerbate health challenges, thereby limiting the effectiveness of health expenditure in driving economic growth (Bilgili et al., 2021; Li et al., 2022). Nigeria's economic structure, which heavily relies on crude oil revenue, further complicates the issue, as fluctuating oil prices affect government revenue and, by extension, health sector funding (Keji, 2021). As a result, sustained economic growth requires a strategic and consistent investment in health-care infrastructure, human resources, and service delivery (Karaaslan & Çamkaya, 2022).
The global COVID-19 pandemic further highlighted the importance of health expenditure in sustaining economic activities. Countries with resilient health-care systems were better able to mitigate the economic shocks associated with the pandemic, while those with fragile health systems, including Nigeria, experienced significant economic downturns (Alhassan et al., 2021). The pandemic underscored the need for increased investments in health-care to enhance economic stability and resilience against future health crises (Sethi et al., 2024).
This study aims to critically examine the impact of health expenditure on Nigeria’s economic growth using Ijebu Ode LGA as a case study. By exploring the extent to which health financing influences economic productivity, this research seeks to provide empirical evidence that will inform policy recommendations aimed at improving health-care funding and enhancing economic performance in Nigeria.
1.2 Statement of the Problem
Despite the well-documented role of health expenditure in driving economic growth, Nigeria continues to struggle with inadequate health-care funding, leading to poor health outcomes and sluggish economic performance (Okoye et al., 2019). The country's health expenditure remains significantly lower than the international standard, contributing to high mortality rates, low life expectancy, and reduced labor force participation (Ibukun & Osinubi, 2020). This underinvestment in health-care services hampers human capital development and limits the country’s ability to achieve sustainable economic growth (Raghupathi & Raghupathi, 2020).
One of the primary challenges in Nigeria’s health financing system is the overreliance on out-of-pocket expenditures, which account for a significant proportion of total health spending (Adebisi et al., 2020). This burden disproportionately affects low-income households, leading to financial hardship and reduced access to essential health-care services (Azam et al., 2019). Furthermore, the inefficiencies in public health expenditure allocation and utilization have resulted in suboptimal health-care outcomes, further constraining economic productivity (Gövdeli, 2019).
At the local government level, health financing is even more precarious. In Ijebu Ode LGA, inadequate funding has led to a shortage of medical personnel, poor health-care infrastructure, and limited access to quality health-care services (Joshua, 2019). These challenges not only affect health outcomes but also have broader economic implications, including reduced workforce efficiency and increased disease burden (Urhie et al., 2020). Given that a healthy population is essential for economic growth, the persistent underfunding of the health sector poses a significant obstacle to Nigeria’s long-term economic development (Somé et al., 2019).
Moreover, while several studies have explored the relationship between health expenditure and economic growth at the national level, there remains a gap in localized research focusing on specific regions such as Ijebu Ode LGA (Jibir & Aluthge, 2019). Understanding how health expenditure influences economic activities at the grassroots level is critical for formulating effective policies that can enhance health-care delivery and stimulate economic growth at both the local and national levels.
This study, therefore, seeks to fill this gap by assessing the impact of health expenditure on economic growth in Ijebu Ode LGA. By examining the challenges and opportunities within the local health-care system, the research aims to provide policy recommendations that can inform government interventions and improve health financing strategies in Nigeria.
1.3 Research Questions
This study seeks to answer the following research questions:
-
What is the impact of health expenditure on economic growth in Nigeria, with a focus on Ijebu Ode Local Government Area?
-
How does public and private health expenditure influence human capital development and labor productivity in Ijebu Ode LGA?
-
What are the key challenges and opportunities in health financing that affect economic growth in Nigeria?
1.4 Research Objectives
The primary objectives of this study are to:
-
Examine the impact of health expenditure on Nigeria’s economic growth, using Ijebu Ode LGA as a case study.
-
Assess the role of public and private health expenditure in improving human capital development and labor productivity.
-
Identify the major challenges and opportunities in health financing and their implications for economic growth in Nigeria.
1.5 Research Hypotheses

H₀ (Null Hypothesis): There is no significant relationship between health expenditure and economic growth in Nigeria.
H₁ (Alternative Hypothesis): There is a significant positive relationship between health expenditure and economic growth in Nigeria.
H₀: Public and private health expenditure do not significantly contribute to human capital development and labor productivity.
H₁: Public and private health expenditure significantly contribute to human capital development and labor productivity.
H₀: Challenges in health financing do not have a significant effect on economic growth in Nigeria.
H₁: Challenges in health financing have a significant effect on economic growth in Nigeria.
1.6 Significance of the Study
This research is significant in several ways. First, it contributes to the body of knowledge on the relationship between health expenditure and economic growth, particularly within the Nigerian context. Previous studies have established the positive correlation between health investment and economic performance (Alhassan et al., 2021; Ogunjimi, 2019), but there remains limited empirical research on localized economies such as Ijebu Ode LGA. By focusing on a specific region, this study provides practical insights into how health financing influences economic activities at the grassroots level.
Second, this study has policy implications for government agencies and policymakers involved in health and economic planning. Understanding the role of health expenditure in economic development will help in designing effective policies aimed at improving health-care financing and ensuring sustainable growth. Given that Nigeria has struggled with inadequate health sector funding (Adebisi et al., 2020), this research highlights the need for increased investment in health-care services to enhance labor productivity and overall economic stability (Okoye et al., 2019).
Additionally, this study is relevant for health-care institutions, private investors, and development organizations seeking to improve health financing strategies. By identifying the challenges and opportunities in Nigeria’s health financing system, stakeholders can make informed decisions on resource allocation and health-care infrastructure development (Bilgili et al., 2021). The findings will also be useful for future researchers interested in examining the economic implications of health-care expenditure in other regions of Nigeria and beyond.
1.7 Scope of the Study
This study focuses on assessing the impact of health expenditure on Nigeria’s economic growth, using Ijebu Ode Local Government Area as a case study. The research covers the period between 2000 and 2024 to capture trends in health financing and economic performance over time. It examines both public and private health expenditures and their contributions to human capital development, labor productivity, and overall economic growth.
The study is limited to health expenditure-related economic indicators such as GDP growth rate, labor force participation, and life expectancy. While acknowledging that other factors (such as education and environmental conditions) also influence economic growth, the study primarily investigates the direct and indirect effects of health financing on economic performance.
Furthermore, the study is restricted to Ijebu Ode LGA due to its strategic economic activities and relevance as a microcosm of Nigeria’s broader economic and health-care challenges. Data will be collected from government reports, health institutions, and economic databases to provide empirical insights into the relationship between health expenditure and economic development.
1.8 Limitations of the Study
Despite its significance, this study is subject to several limitations:
-
Data Availability and Reliability: The study relies on secondary data from government and institutional reports, which may contain inconsistencies or gaps in health expenditure and economic performance records (Ibukun & Osinubi, 2020).
-
Regional Focus: While the study examines Ijebu Ode LGA as a case study, its findings may not be fully generalizable to other parts of Nigeria due to regional variations in health-care financing and economic structures (Jibir & Aluthge, 2019).
-
External Economic Factors: The study acknowledges that external factors such as global economic downturns, inflation, and policy changes may also influence economic growth, but it primarily focuses on health expenditure as the key variable of interest (Sethi et al., 2024).
