Background of the Study
Income distribution is a critical factor that influences economic growth by affecting consumption, savings, and investment patterns across different segments of society. In Nigeria, unequal income distribution has been identified as a major barrier to sustainable economic development. When income is concentrated within a small segment of the population, the overall consumption multiplier tends to be lower, as high-income households are more likely to save a larger portion of their earnings compared to low-income households (Akinyemi, 2023). Conversely, more equitable income distribution can lead to a broader base of consumer spending, thereby stimulating aggregate demand and contributing positively to GDP growth.
The theoretical framework for this study is anchored in both Keynesian and neoclassical economic theories. Keynesian theory emphasizes the role of effective demand and aggregate consumption in driving economic growth, while neoclassical perspectives focus on how income inequality can distort incentives and reduce overall productivity. In Nigeria, income disparities have been exacerbated by factors such as regional imbalances, varying access to education and healthcare, and differences in employment opportunities. Empirical studies from similar emerging economies have demonstrated that countries with more balanced income distribution tend to experience higher and more sustainable economic growth (Ogunleye, 2024).
Recent policy initiatives in Nigeria have aimed to address income inequality through targeted social programs, improved access to education, and measures to boost employment opportunities in underdeveloped regions. However, the overall impact of these policies on economic growth remains debatable. This study intends to assess the impact of income distribution on economic growth by analyzing recent income data, consumption patterns, and GDP trends. By comparing periods of high and low income equality, the research seeks to determine how shifts in income distribution affect economic performance and to offer policy recommendations for promoting inclusive growth.
Statement of the Problem
Despite numerous interventions aimed at reducing income inequality in Nigeria, significant disparities persist, adversely affecting economic growth. The central problem is that unequal income distribution limits the overall consumption capacity of the majority of the population, thereby dampening aggregate demand. While high-income households tend to save a larger fraction of their income, low-income households spend nearly all of their earnings, yet the overall contribution of these expenditures to GDP is muted when income gains are concentrated within a narrow segment of society (Chukwu, 2023).
Moreover, regional disparities and limited access to quality education and healthcare further exacerbate income inequality, creating pockets of underdevelopment that hinder national economic progress. The lack of an effective mechanism to redistribute income equitably means that growth benefits remain concentrated, leading to cyclical economic imbalances and social unrest. External factors such as fluctuations in global oil prices and political instability further complicate efforts to achieve a more equitable income distribution, as government revenues and spending patterns become unpredictable.
This study addresses the need to understand the extent to which income distribution influences economic growth in Nigeria. By identifying the key channels through which income inequality impacts aggregate demand and productivity, the research will provide insights into why policy measures have often failed to produce the desired inclusive growth outcomes. The findings of this study are expected to guide policymakers in designing interventions that not only reduce income disparities but also harness the potential of a more balanced income distribution to drive sustainable economic growth.
Objectives of the Study
