The Effect of Corruption on Public Investment and Economic Development in Nigeria

Chapter One

1.1 Background of the Study
Corruption remains one of the most pressing challenges facing developing nations. In Nigeria, it has weakened institutions, distorted public policies, and reduced citizens’ trust in governance. Although the government invests heavily in infrastructure and social services, corruption often limits the effectiveness of such investments (Adewale, 2022).

Public investment plays a crucial role in promoting economic growth. It funds roads, schools, hospitals, and energy projects that support productivity and welfare. However, when funds meant for development are diverted or misused, project completion suffers. Consequently, public trust declines, and economic progress slows.

Over the years, Nigeria has lost billions of naira to corrupt practices such as embezzlement, bribery, and inflated contracts. These activities not only waste public resources but also discourage foreign investors. Moreover, corruption undermines transparency and accountability in the management of public funds. Hence, economic development becomes uneven, and poverty levels rise.

Although various anti-corruption agencies exist, including the Economic and Financial Crimes Commission (EFCC) and the Independent Corrupt Practices Commission (ICPC), the persistence of corruption indicates deep systemic issues. Many public officers still manipulate procurement processes and divert resources for personal gain. Furthermore, weak enforcement of laws allows such misconduct to continue unchecked.

In addition, corruption affects public investment efficiency by increasing project costs and reducing quality. For instance, poorly constructed infrastructure requires frequent repairs, which consume additional funds. As a result, the economy bears the long-term cost of short-term greed. Therefore, examining how corruption influences public investment and economic development is essential for policy reform and sustainable growth.

1.2 Statement of the Problem
Despite numerous reforms, corruption continues to hinder Nigeria’s development efforts. Funds allocated for public projects often fail to produce expected outcomes due to mismanagement and fraud. Moreover, the quality of infrastructure remains low, and citizens receive limited value from government spending. These persistent failures raise concerns about how corruption distorts investment priorities and weakens economic progress.

1.3 Objectives of the Study
The main objective of this study is to examine the effect of corruption on public investment and economic development in Nigeria.
Specific objectives include:

1. To identify the major forms of corruption affecting public investment.

2. To assess how corruption influences the efficiency of public expenditure.

3. To evaluate the relationship between corruption and economic development in Nigeria.

1.4 Research Questions

1. What are the common types of corruption that affect public investment in Nigeria?

2. How does corruption reduce the efficiency of government spending?

3. What is the impact of corruption on Nigeria’s overall economic development?

1.5 Significance of the Study
This research is important because it sheds light on how corruption undermines national development. Moreover, it offers insights that can help policymakers strengthen transparency and accountability in public finance. The study also contributes to the growing body of literature on governance and development economics. Furthermore, it encourages civic organizations to advocate for stronger anti-corruption measures and improved monitoring of public projects.

1.6 Scope of the Study
The study focuses on Nigeria from 2000 to 2024, a period that covers multiple government administrations and anti-corruption initiatives. It analyzes how corruption has affected public investment in infrastructure, education, and health. Additionally, it explores how governance quality influences overall economic outcomes.
