Background of the Study
Minimum wage policies are a central component of labor market regulation aimed at ensuring a basic standard of living for workers. In Nigeria, debates over the optimal minimum wage level have intensified in recent years as policymakers attempt to balance the objectives of poverty alleviation and job creation. Recent adjustments implemented between 2023 and 2025 have sparked both support and criticism among various stakeholders. Proponents argue that a higher minimum wage enhances workers’ purchasing power and stimulates domestic demand, while critics contend that it may lead to reduced hiring, particularly among small and medium-sized enterprises (SMEs) with tight profit margins (Adewale, 2023). Moreover, the interplay between minimum wage increases and employment levels is further complicated by regional economic disparities, differences in sectoral productivity, and the overall business climate in Nigeria.
Over the past decade, Nigeria’s economy has witnessed significant fluctuations in employment patterns, partly due to macroeconomic instability and policy shifts. As industries adjust to changes in labor costs, empirical evidence suggests that increases in the minimum wage can lead to both positive and negative outcomes. For example, some studies indicate that moderate wage increases may boost employee morale and productivity, leading to enhanced overall firm performance. In contrast, excessive wage hikes without corresponding improvements in productivity could result in higher unemployment, particularly in labor-intensive sectors (Okafor, 2024). Additionally, the informal sector—which constitutes a large share of Nigeria’s employment landscape—remains largely unaffected by formal minimum wage policies, raising questions about the policy’s overall effectiveness in addressing employment challenges. Against this backdrop, the current study seeks to investigate the net impact of minimum wage policies on formal employment levels in Nigeria, while considering the differential effects across regions and industries. By employing both quantitative analyses and qualitative case studies, this research aims to generate evidence that can inform future policy adjustments and contribute to a more nuanced understanding of the minimum wage–employment nexus in a developing economy (Akinyemi, 2025).
Statement of the Problem
Despite the well-intentioned nature of minimum wage policies, Nigeria has experienced mixed outcomes with regard to employment levels. A key concern is that periodic increases in the minimum wage may lead to higher labor costs, forcing employers—especially in the private sector—to curtail hiring or substitute labor with automation. This contraction in formal employment could exacerbate unemployment and drive more workers into the informal sector, where labor protections are minimal (Adewale, 2023). In addition, the heterogeneous impact of wage increases across different regions and sectors creates disparities in employment opportunities. Employers in less industrialized or economically depressed regions might find it particularly challenging to absorb increased labor costs, further deepening regional inequalities. Furthermore, the lack of coordinated policies that simultaneously promote skills development and productivity enhancement means that wage increases may not translate into commensurate gains in output, thereby undermining the broader economic objectives of minimum wage adjustments (Okafor, 2024). This study seeks to address these concerns by rigorously examining the causal relationship between minimum wage policies and employment levels in Nigeria, identifying factors that mediate this relationship, and proposing policy measures to mitigate any adverse effects.
Objectives of the Study
To assess the impact of recent minimum wage increases on formal employment levels in Nigeria.
To identify the mediating factors that influence the relationship between minimum wage adjustments and job creation.
To propose policy recommendations that balance wage growth with sustainable employment.
Research Questions
What has been the effect of recent minimum wage increases on formal employment levels in Nigeria?
How do sectoral and regional factors mediate the impact of minimum wage policies on employment?
What policy measures can be implemented to mitigate negative employment effects while promoting wage growth?
Research Hypotheses
H₁: Increases in the minimum wage are significantly associated with a reduction in formal employment levels in Nigeria.
H₂: The impact of minimum wage policies on employment is moderated by sectoral productivity and regional economic conditions.
H₃: Complementary policies, such as skills development programs, can mitigate the negative effects of minimum wage hikes on employment.
Scope and Limitations of the Study
This study focuses on formal employment sectors across Nigeria from 2015 to 2025, using national labor statistics, firm-level data, and qualitative interviews. Limitations include potential data inaccuracies in labor surveys and challenges in isolating the effects of minimum wage policies from other macroeconomic factors.
