Background of the Study
Public expenditure is a vital tool for stimulating economic growth and improving living standards by funding essential services such as healthcare, education, and infrastructure. In Nigeria, the government’s allocation of public funds has a direct bearing on both economic growth and consumer income. The theoretical framework underlying this relationship is based on the Keynesian multiplier effect, which posits that increased public spending can lead to higher aggregate demand, thereby boosting national income (Obi, 2023). Recent trends in Nigeria have shown significant fluctuations in public expenditure, influenced by variations in oil revenues and fiscal policy adjustments. These fluctuations, in turn, have impacted the pace and sustainability of economic growth and the distribution of income among consumers.
Empirical studies in emerging economies reveal that strategic public expenditure can yield significant benefits, including job creation, improved productivity, and enhanced consumer purchasing power. However, the effectiveness of public expenditure in translating into economic growth and higher consumer incomes depends on the efficiency and targeting of the spending. In Nigeria, challenges such as corruption, misallocation of resources, and bureaucratic inefficiencies have often diluted the potential positive impacts of public spending (Ike, 2024). Nonetheless, targeted investments in critical sectors have the potential to generate lasting improvements in economic performance.
This study aims to assess the impact of public expenditure on both economic growth and consumer income in Nigeria. By analyzing recent fiscal data and consumer income trends, the research will evaluate whether increases in public spending have led to proportional improvements in economic output and individual incomes. The study will further explore the mechanisms through which public expenditure influences these outcomes, such as through the creation of jobs, enhancement of infrastructure, and improvement in human capital. Ultimately, the findings will offer insights into the efficiency of public spending and provide policy recommendations for optimizing expenditure to foster sustainable economic growth and equitable income distribution.
Statement of the Problem
Despite significant public expenditure in critical sectors, Nigeria’s economic growth and consumer income levels have not always met policy expectations. One major problem is the apparent disconnect between the volume of government spending and its impact on overall economic performance. While fiscal policies have increased public expenditure, inefficiencies in fund allocation, corruption, and administrative delays have often resulted in suboptimal outcomes (Obi, 2023). This has led to concerns that public expenditure, rather than acting as a catalyst for growth, may be contributing to fiscal imbalances and uneven income distribution.
Moreover, external factors such as global economic fluctuations and domestic political instability further complicate the relationship between public expenditure, economic growth, and consumer income. The lack of a robust monitoring framework to track the real-time impact of government spending on these economic indicators has resulted in persistent uncertainties. Consequently, policymakers face challenges in formulating strategies that effectively channel public expenditure into growth-enhancing sectors while ensuring that the benefits are evenly distributed among consumers (Ike, 2024). The persistence of these issues necessitates a thorough examination of the role of public expenditure, with an emphasis on identifying the channels through which it influences economic outcomes and consumer welfare.
