ABSTRACT
This study was carried out to assess the impact of government expenditure on economic growth in Nigeria using Delta State as a case study. The study was specifically carried out to evaluate the impact of government education expenditure on economic growth in Delta State, investigate the impact of government health expenditure on economic growth in Delta State, and examine the impact of public debt on economic growth in Delta State. The study employed the ex-post facto research design. The study population comprised annual fiscal and economic records relating to government education expenditure, government health expenditure, public debt, and economic growth in Delta State from 2016 to 2025, while the entire population of 10 annual observations was adopted as the sample size. Secondary data were used for the study and were obtained from official government publications and relevant fiscal records. The data collected were analyzed using descriptive statistics, correlation analysis, Analysis of Variance (ANOVA), multiple regression model (MRM), and multicollinearity test with the aid of E-Views statistical software. From the data obtained and analyzed, the findings revealed that government education expenditure has a significant positive impact on economic growth at β = 0.0486, P = 0.0214. The study also showed that government health expenditure has a significant positive impact on economic growth at β = 0.0362, P = 0.0428. Likewise, public debt was found to have a positive but insignificant impact on economic growth at β = 0.0098, P = 0.0587. The study further revealed that the explanatory variables jointly explained approximately 98.83% of the variations in economic growth at R² = 0.9883. The study concluded that government education expenditure and government health expenditure significantly contribute to economic growth in Delta State, while public debt exerts a positive but statistically insignificant influence on economic growth. The study therefore recommends that the Delta State Government should increase investment in the education and health sectors, ensure efficient utilization of borrowed funds for productive projects, strengthen fiscal accountability mechanisms, and prioritize expenditure policies that promote sustainable economic growth.
Keywords: Government Expenditure, Economic Growth, Education Expenditure, Health Expenditure, Public Debt, Delta State.

CHAPTER ONE
INTRODUCTION (Preview)
1.1 Background of the Study
Government expenditure has remained one of the most significant instruments through which governments influence economic growth and development across the world. Governments allocate public resources to key areas like education, health, infrastructure, and social services to enhance productivity, build human capital, and establish a climate for sustainable economic growth. Thus the connection between public spending and economic growth has been investigated in the economic literature and the scholars have analysed how much public spending helps the increase in the national output and welfare. Onifade et al. (2020a) noted that government spending is the stimulator of economic activities as it creates institutional and physical structure conducive to economic growth. In the same light, Abada and Manasseh (2020) contended that public expenditure is a key tool in macro-economic management as it ultimately affect investment, consumption and aggregate demand. This is supported by Bappahyaya et al. (2020), who found that the role of government expenditure was productivity increasing and thus conducive for long-term economic performance, and Aluthge et al. (2021), who argued that whether a public expenditure can positively affect economic growth or not depends on how it is spent and how efficiently it is spent.
In this international context, the role of government spending has become more prominent in both growth and welfare enhancement in developing economies. In many emerging countries, public spending is channeled to areas that can help to build human capital and promote productive activities. Rapheal (2021) argues that the government spending can have a positive effect on economic growth if directed towards areas that have a multiplier effect. Similarly, Akinwumi (2020) highlighted the significance of investment in social and economic services on the socioeconomic development through the provision of education, health care and public infrastructure. Moreover, Nwankwo et al (2022) stated that there are direct and indirect linkages between government spending and economic growth, especially when the government's spending is consistent with developmental plans. In this regard, Ugochukwu and Oruta (2021) observed that disaggregated government spending often results in different growth outcomes as they noted that, in general, government spending in productive sectors has a higher positive growth impact than general government spending.
Consequently, increasing attention has been directed toward education and health expenditures because of their strategic role in human capital development. Education spending increases the skills, knowledge and capacities of the workforce, making them more productive in economic activities. According to Bewaji et al. (2021), the investment in education has great impact on economic growth in terms of labour productivity and innovation. Also, Christopher, Akpan and Ologunla 2025b showed that government expenditure on education can have significant impact on long run economic development given its effect on human resource development. Similarly, health expenditure has also been identified as significant determinant of economic performance as a healthy population is more productive and can effectively contribute to national development. Yusuf (2020) shows that government health expenditure can strengthen economic growth through better health outcomes and increased efficiency of the workforce. Musa, Ismail and Magaji (2024) also noted the importance of public investment in health services in relation to the accumulation of human capital in the overall development agenda of the economy.
The debate over public spending has also led to an increasing emphasis on public indebtedness as a part of the overall fiscal picture. Public debt is frequently a source of financing and a way for a government to generate resources to make public investments and development projects. Debt financing, if managed effectively, can be used to fund expenditures that can help to improve productive capacity and to stimulate economic growth. Omitogun et al. (2023) indicated that the impact of government spending on growth is closely linked to the fiscal instruments employed in financing the government spending such as public borrowing. Ikechukwu, Maku and Ashakah (2025) similarly posited that government spending and debt management are interrelated aspects of economic policy which affect the outcomes of growth. Moreover, Jibir et al. (2023) pointed out that the impact and efficiency of public spending is reliant on the sustainable generation of revenues and proper fiscal policies. In keeping with this view, Emmanuel, Usifoh and Adu (2024) identified the efficiency in resource allocation in public finance systems as a key determinant of the effects of public expenditure and public debt on economic growth.
Against this broader national and theoretical backdrop, the relationship between government expenditure and economic growth has become an important area of inquiry within Nigeria and its constituent states. The fiscal structure of Nigeria shows a significant role for the government in the development sectors for promoting economic advancement such as education, health, infrastructure, etc. Musa and Ismail (2023) and Nwakwanogo (2025) showed that government spending is an important determinant of Nigeria's economic performance especially when government spending is channeled into productive areas which improves human capital and economic services. In this context, Delta State is a significant case in which subnational Government spending in each sector can be analyzed to determine the impact on economic growth in Delta State. Delta State is one of the economically important states in Nigeria with huge public investment activities, making it an appropriate place to assess the impact of public expenditure on growth outcome. Hence, this study emphasizes the effects of government education expenditure, government health expenditure and public debt on economic growth in Delta State.

1.2 Statement of the Problem
Government spending will be used as a medium to stimulate economic growth, focusing on key areas like education and health; the Public debt is expected to be used to supplement the financing of development programmes that will improve productivity and socioeconomic welfare. In a best-case scenario, this would mean that a rise in government spending on education should lead to better human capital development, a rise in government spending on workers should lead to greater wellbeing and labour productivity, and a rise in public debt should be used to finance projects that lead to greater economic growth. But empirical literature on the fiscal/economic growth nexus in Nigeria is inconclusive. The findings of some studies such as Rapheal (2021), Aluthge et al. (2021) and Onifade et al. (2020a) indicated positive impacts of government spending on economic growth while other studies like Omitogun et al. (2023) and Jibr et al. (2023) have reported mixed impacts across components of government spending and over the years. This disagreement leads to uncertainty about the impact of these policy measures – education expenditure, health expenditure, and public debt – on economic growth, especially at the subnational level. This uncertainty has an impact on fiscal planning and resource allocation decisions, as policymakers need empirical evidence on the areas of expenditure that create the largest economic benefits.
Moreover, available research has focussed on the national level in Nigeria, analyzing government expenditure and economic growth with nation-wide data without taking account of the specific fiscal and economic conditions in each state. For example, Yusuf (2020), Bewaji et al. (2021), Christopher et al. (2025b), and Musa et al. (2024) have analyzed sectoral expenditures and economic growth in Nigeria and Nwankwo et al. (2022) and Ikechukwu et al. (2025) have analyzed broader government expenditure-growth relationships at the federal level. While much has been written on the results of these studies, little empirical work has been conducted on Delta State, which is an important economic state and has a large amount of public spending activity. As a result there is a gap in contextual knowledge about the impact of the government education expenditure, government health expenditure and public debt on economic growth in the state. This research aims to address this gap by bringing out empirical evidence from Delta State, supplementing the current literature beyond the national level analysis, which can contribute to evidence-based fiscal decision making and economic development plans.

CHAPTER FOUR; PRESENTATION AND ANALYSIS
MAJOR FINDINGS (Preview)
The analysis results were presented in tables. Based on the results obtained from the analysis, the following findings are made:

i. The study found that government expenditure on education positively and significantly affects economic growth in Delta State, as evidenced by a regression coefficient (β) of 0.0486 and a p-value of 0.0214 (p < 0.05). The corresponding hypothesis test led to the rejection of the null hypothesis, indicating that government expenditure on education significantly contributes to economic growth in Delta State.

ii. The study found that government expenditure on health positively and significantly affects economic growth in Delta State, as evidenced by a regression coefficient (β) of 0.0362 and a p-value of 0.0428 (p < 0.05). The corresponding hypothesis test led to the rejection of the null hypothesis, indicating that government expenditure on health significantly contributes to economic growth in Delta State.

iii. The study found that public debt has a positive but statistically insignificant effect on economic growth in Delta State, as evidenced by a regression coefficient (β) of 0.0098 and a p-value of 0.0587 (p > 0.05). The corresponding hypothesis test led to the acceptance of the null hypothesis, indicating that public debt does not significantly influence economic growth in Delta State during the period under review.

iv. The study found that government expenditure on education, government expenditure on health, and public debt jointly have a significant effect on economic growth in Delta State, as evidenced by an F-statistic of 168.591 and a p-value of 0.0000 (p < 0.05). The coefficient of determination (R²) of 0.9883 further revealed that the explanatory variables account for 98.83% of the variation in economic growth, leading to the rejection of the null hypothesis of no joint significant effect.
