THE IMPACT OF EFFECTIVE PUBLIC SECTOR ACCOUNTING ON PUBLIC FUNDS MANAGEMENT IN NIGERIA

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Public sector accounting is a specialized branch of accounting that deals with the recording, classification, analysis, summarization, and reporting of financial transactions of government entities. Unlike private sector accounting, which focuses on profit measurement and wealth creation for shareholders, public sector accounting focuses on budgetary compliance, stewardship of public funds, accountability to citizens, and the efficient and effective use of public resources. Public sector accounting operates within a legal and regulatory framework that includes constitutions, financial regulations, appropriation acts, and public financial management laws. The primary objective of public sector accounting is to provide information that enables stakeholders—legislatures, oversight bodies, citizens, creditors, and international partners—to assess whether public funds have been collected and spent in accordance with legal requirements and for the intended purposes (Premchand, 2017). (Premchand, 2017)

Public funds management refers to the processes, systems, and controls used by governments to plan, allocate, monitor, and account for public financial resources. Effective public funds management encompasses budget preparation (estimating revenues and expenditures), budget execution (disbursing funds in accordance with appropriations), cash management (maintaining adequate liquidity), debt management (borrowing and repayment), procurement (acquiring goods and services), accounting (recording transactions), financial reporting (producing financial statements), and audit (verifying compliance). The ultimate goals of public funds management are fiscal discipline (aggregate expenditure does not exceed available resources), allocative efficiency (resources are directed to strategic priorities), and operational efficiency (resources are used to achieve outputs at minimum cost). These three objectives are often referred to as the “three pillars” of public financial management (Schick, 2018). (Schick, 2018)

The importance of effective public funds management cannot be overstated. Governments collect revenues from citizens (taxes, fees, levies) and borrow from domestic and international sources. These funds are entrusted to public officials who are expected to use them for the public good—providing essential services such as education, healthcare, infrastructure, security, and social protection. When public funds are mismanaged—through waste, inefficiency, fraud, or corruption—services deteriorate, public trust erodes, economic growth slows, and poverty deepens. In developing countries like Nigeria, where public resources are scarce relative to needs, effective public funds management is even more critical. Every Naira lost to mismanagement is a Naira that could have built a school, equipped a clinic, or paid a teacher’s salary (World Bank, 2020). (World Bank, 2020)

Public sector accounting is the foundation of effective public funds management. Without accurate, complete, timely, and reliable accounting information, government officials cannot make informed decisions about resource allocation; legislatures cannot exercise oversight; auditors cannot detect irregularities; and citizens cannot hold government accountable. The accounting system provides the data for budget preparation (historical trends in revenues and expenditures), budget execution (tracking actual expenditures against appropriations), financial reporting (annual financial statements), and audit (verification of compliance). Weak accounting systems produce unreliable information, leading to poor decisions, undetected fraud, and loss of public trust (Khan and Hildreth, 2019). (Khan and Hildreth, 2019)

The Nigerian public sector accounting system has undergone significant reforms over the past two decades. Prior to 2005, Nigeria operated a cash basis of accounting, where transactions were recorded only when cash was received or paid. The cash basis was simple but provided incomplete information about assets, liabilities, and commitments. In 2005, the Federal Government adopted the accrual basis of accounting (modified accrual) for key ministries, departments, and agencies (MDAs), and later committed to full accrual International Public Sector Accounting Standards (IPSAS). The adoption of the Government Integrated Financial Management Information System (GIFMIS) in 2012 was a major milestone. GIFMIS is an integrated computerized financial management system that automates budgeting, commitment control, procurement, payment processing, accounting, and reporting (FRC, 2018). (FRC, 2018)

The International Public Sector Accounting Standards (IPSAS) provide a global framework for public sector accounting. IPSAS are issued by the IPSAS Board (IPSASB) and are based on IFRS but adapted for the public sector context. Key IPSAS standards relevant to public funds management include: IPSAS 1 (Presentation of Financial Statements), IPSAS 2 (Cash Flow Statements), IPSAS 3 (Accounting Policies), IPSAS 12 (Inventories), IPSAS 17 (Property, Plant and Equipment), IPSAS 19 (Provisions, Contingent Liabilities and Contingent Assets), and IPSAS 23 (Revenue from Non-Exchange Transactions). Nigeria has committed to adopting accrual-basis IPSAS, but implementation has been incomplete. Some MDAs still use cash-basis accounting, and the quality of IPSAS compliance varies widely (IPSASB, 2022). (IPSASB, 2022)

The legal framework for public funds management in Nigeria includes several key instruments. The Constitution of the Federal Republic of Nigeria (1999, as amended) establishes the Consolidated Revenue Fund (CRF) and requires that no expenditure be incurred without appropriation by the National Assembly. The Fiscal Responsibility Act (2007) establishes the Fiscal Responsibility Commission (FRC) to enforce fiscal discipline, requiring that government budgets be based on realistic revenue and expenditure estimates. The Public Procurement Act (2007) establishes the Bureau of Public Procurement (BPP) to regulate procurement, requiring competitive bidding and due process. The Financial Reporting Council (FRC) of Nigeria Act (2011) establishes the FRC to set accounting standards (including IPSAS) and ensure compliance. The Companies and Allied Matters Act (CAMA) 2020 (for government-owned enterprises) requires audited financial statements (Federal Republic of Nigeria, 1999; 2007a; 2007b; 2011; 2020). (Federal Republic of Nigeria, 1999; 2007a; 2007b; 2011; 2020)

Despite these legal and institutional reforms, Nigeria faces significant challenges in public funds management. The Office of the Auditor-General of the Federation (OAuGF) has consistently reported substantial financial irregularities in its annual audit reports. The 2019 Auditor-General’s report documented: unauthorized expenditures (₦50 billion), payments without supporting documents (₦45 billion), contract awards without due process (₦30 billion), and non-retirement of advances (₦20 billion). Similar findings appear year after year, suggesting that the accounting system is not effectively controlling public funds. The Auditor-General has repeatedly recommended strengthening the accounting system, but recommendations have not been implemented (Auditor-General of the Federation, 2020). (Auditor-General of the Federation, 2020)

The Government Integrated Financial Management Information System (GIFMIS) was expected to revolutionize public funds management. GIFMIS integrates budgeting (budget preparation and approval), procurement (contract awards), commitment control (ensuring commitments do not exceed budgets), payment processing (vendor payments, employee salaries), accounting (recording transactions), and reporting (financial statements). In theory, GIFMIS should prevent unauthorized expenditures because the system will reject any transaction that exceeds budget limits or lacks proper approval. In practice, however, GIFMIS has been plagued by implementation challenges: system downtime, lack of trained personnel, data entry errors, and overrides (where authorized officials bypass controls). The effectiveness of GIFMIS in managing public funds has not been rigorously evaluated (Okoye, Okafor, and Nnamdi, 2020). (Okoye et al., 2020)

Several specific weaknesses in the Nigerian public sector accounting system undermine public funds management. Weak commitment control: many MDAs do not record commitments (purchase orders, contracts) before payments, leading to expenditure exceeding available appropriations. Manual override of controls: GIFMIS has override features that allow authorized officials to bypass system controls; these overrides are not always justified or documented. Lack of integration: some MDAs use separate payroll systems, procurement systems, or asset registers that are not integrated with GIFMIS, creating opportunities for error and fraud. Inadequate internal controls: many MDAs lack effective internal controls (segregation of duties, authorizations, reconciliations), enabling unauthorized expenditures to occur without detection. Poor record keeping: some MDAs do not maintain complete or accurate accounting records, making it impossible to track public funds or detect irregularities (Adeyemi and Ogundipe, 2020). (Adeyemi and Ogundipe, 2020)

The consequences of poor public funds management in Nigeria are severe. Waste: funds are spent on unnecessary or overpriced goods and services. Fraud: public funds are stolen through inflated contracts, ghost workers, fake suppliers, and embezzlement. Inefficiency: funds are not allocated to their highest-value uses, reducing the impact of public spending on development outcomes. Reduced public trust: citizens lose confidence in government when they perceive that public funds are mismanaged. Poor service delivery: when funds are diverted, essential services (education, health, infrastructure) suffer. Reduced foreign investment: international investors and development partners are reluctant to invest in countries with weak public funds management (BudgIT, 2023). (BudgIT, 2023)

The COVID-19 pandemic has created new challenges for public funds management and highlighted the importance of effective accounting. The government released substantial funds for pandemic response (health equipment, social protection, economic stimulus). However, there were widespread reports of fraud, waste, and mismanagement of COVID-19 funds. The Auditor-General reported that billions of Naira in COVID-19 funds could not be accounted for due to poor record keeping. The pandemic exposed weaknesses in the accounting system and underscored the need for strengthening (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

The Open Government Partnership (OGP) and other transparency initiatives have increased demand for public funds information. Citizens, civil society organizations, and international development partners are calling for greater transparency and accountability in public spending. The accounting system is the source of this information. If the accounting system does not produce accurate, timely, and accessible expenditure information, transparency initiatives cannot succeed. Therefore, strengthening public sector accounting is a prerequisite for achieving transparency and accountability goals (BudgIT, 2023). (BudgIT, 2023)

International development partners (World Bank, IMF, DFID, EU) have provided financial and technical support for public financial management reforms in Nigeria, including GIFMIS implementation and IPSAS adoption. These partners require evidence on whether their investments have been effective. This study provides such evidence, enabling development partners to assess the return on their investments and to design future support programs (World Bank, 2020). (World Bank, 2020)

Several theories explain the relationship between public sector accounting and public funds management. Agency theory (Jensen and Meckling, 1976) suggests that government officials (agents) may not act in the best interests of citizens (principals). Public sector accounting reduces information asymmetry by providing citizens and oversight bodies with information about agent actions, enabling monitoring. Stewardship theory (Donaldson and Davis, 1991) suggests that government officials are motivated to act responsibly if they are trusted and empowered; accounting supports stewardship by providing information that officials need to manage effectively. Institutional theory (DiMaggio and Powell, 1983) suggests that accounting systems are adopted not only for their technical benefits but also for legitimacy: governments adopt modern accounting systems (IPSAS, GIFMIS) to signal that they are modern, transparent, and accountable. Public financial management theory (Schick, 2018) provides a framework for understanding how accounting contributes to fiscal discipline, allocative efficiency, and operational efficiency. (DiMaggio and Powell, 1983; Donaldson and Davis, 1991; Jensen and Meckling, 1976; Schick, 2018)

Finally, the relationship between public sector accounting and public funds management must be understood in the context of Nigeria’s governance environment. Nigeria faces challenges of corruption, political interference, weak rule of law, and limited technical capacity. These challenges may limit the effectiveness of even the best-designed accounting system. Reforming the accounting system alone is not sufficient; broader governance reforms (anti-corruption, civil service reform, judicial reform) are also needed. This study examines the interaction between accounting and the governance environment (Adeyemi and Ogundipe, 2020). (Adeyemi and Ogundipe, 2020)

1.2 Statement of the Problem

Despite significant investments in public sector accounting reforms in Nigeria—including the adoption of IPSAS, the implementation of GIFMIS, and the introduction of integrated payroll systems—public funds management remains weak. This problem manifests in persistent financial irregularities, budget overruns, waste, fraud, poor service delivery, and erosion of public trust. The statement of this problem is supported by the following specific issues.

First, persistent financial irregularities documented by the Auditor-General of the Federation. Year after year, the Auditor-General reports substantial unauthorized expenditures, payments without supporting documents, contract awards without due process, and non-retirement of advances. The 2019 report documented over ₦50 billion in unauthorized expenditures, ₦45 billion in payments without supporting documents, and ₦30 billion in contract awards without due process (Auditor-General of the Federation, 2020). These findings suggest that the accounting system is not effectively controlling public funds.

Second, poor budget implementation. Nigeria’s budget implementation rates are consistently low, not because of lack of funds but because of poor planning and weak expenditure control. The Budget Office of the Federation reports that capital budget implementation averages 60-70% annually, while recurrent budget implementation exceeds 90%. The gap between appropriated and actual expenditure reflects weaknesses in public funds management (lack of commitment control, poor cash management) (BudgIT, 2023). (BudgIT, 2023)

Third, GIFMIS implementation challenges. GIFMIS was intended to strengthen public funds management, but implementation has been problematic. Studies have documented: system downtime (GIFMIS is unavailable for days or weeks, forcing MDAs to use manual processes), lack of trained personnel (many MDAs lack staff who can operate GIFMIS effectively), data entry errors (incorrect coding of transactions), and override abuse (officials bypass system controls without justification). These challenges limit the effectiveness of GIFMIS in managing public funds (Okoye et al., 2020). (Okoye et al., 2020)

Fourth, weak internal controls. Many MDAs lack effective internal controls: segregation of duties is absent (same person authorizes, records, and pays), approvals are not documented, reconciliations are not performed, and assets are not safeguarded. The absence of internal controls creates opportunities for unauthorized expenditures to occur without detection. The Auditor-General has repeatedly recommended strengthening internal controls, but recommendations have not been implemented (Adeyemi and Ogundipe, 2020). (Adeyemi and Ogundipe, 2020)

Fifth, lack of integration between financial systems. Some MDAs use separate payroll systems, procurement systems, asset registers, and GIFMIS that are not integrated. This lack of integration creates opportunities for error and fraud: ghost workers can exist on the payroll system without being detected, procurement contracts can be awarded without budget checks, and assets can be purchased without being recorded. Integration is essential for effective public funds management (Khan and Hildreth, 2019). (Khan and Hildreth, 2019)

Sixth, poor record keeping. Many MDAs do not maintain complete or accurate accounting records. Some MDAs do not record commitments (purchase orders, contracts) before payments, making it impossible to know whether expenditures will exceed appropriations. Some MDAs do not reconcile bank accounts, leaving unreconciled differences undetected. Some MDAs do not retain source documents (invoices, receipts, contracts), making it impossible to verify transactions. Poor record keeping undermines all other public funds management mechanisms (Premchand, 2017). (Premchand, 2017)

Seventh, lack of enforcement of audit recommendations. The Auditor-General issues audit reports with recommendations for corrective action. However, these recommendations are rarely implemented. The Public Accounts Committee (PAC) of the National Assembly is responsible for reviewing audit reports and holding MDAs accountable, but the PAC is understaffed, underfunded, and lacks technical capacity. Without enforcement, MDAs have no incentive to strengthen public funds management (Auditor-General of the Federation, 2020). (Auditor-General of the Federation, 2020)

Eighth, COVID-19 expenditure irregularities. During the pandemic, the government released substantial funds for pandemic response. However, the Auditor-General reported that billions of Naira in COVID-19 funds could not be accounted for due to poor record keeping. Some MDAs made payments without supporting documents; others failed to retire advances. The pandemic exposed the fragility of Nigeria’s public funds management system (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

Ninth, the relationship between public sector accounting and public funds management has not been adequately studied in Nigeria. While many studies have described the accounting system (GIFMIS, IPSAS) and many studies have documented expenditure irregularities, few studies have systematically analyzed the causal relationship between accounting system characteristics (commitment control, budget control, internal controls, integration, record keeping) and public funds management outcomes (budget credibility, expenditure arrears, audit irregularities, service delivery). Which specific accounting system features have the strongest influence on public funds management? How does implementation quality (staff training, system functionality) affect outcomes? What are the barriers to effective accounting system implementation? This study addresses these questions (Okoye et al., 2020). (Okoye et al., 2020)

Tenth, a significant gap in the literature on public financial management in Nigeria. Most existing studies focus on federal government MDAs, ignoring state and local government accounting systems. However, state and local governments account for a significant proportion of public expenditure (approximately 50% of total public expenditure). State and local governments also have weaker accounting systems than the federal government, and public funds management problems are more severe at these levels. This study includes state and local governments to provide a comprehensive picture (BudgIT, 2023). (BudgIT, 2023)

Therefore, the central problem this study seeks to address can be stated as: Despite significant investments in public sector accounting reforms in Nigeria—including IPSAS adoption, GIFMIS implementation, and integrated payroll systems—public funds management remains weak. Persistent financial irregularities, budget overruns, waste, fraud, poor service delivery, and erosion of public trust indicate that the accounting system is not effectively managing public funds. The specific weaknesses in the accounting system (commitment control, internal controls, integration, record keeping, enforcement) and their influence on public funds management have not been systematically documented. This study addresses this gap by empirically examining the impact of effective public sector accounting on public funds management in Nigeria, covering federal, state, and local government levels.

1.3 Aim of the Study

The aim of this study is to critically examine the impact of effective public sector accounting on public funds management in Nigeria, with a view to identifying the specific accounting system features (commitment control, budget control, internal controls, integration, record keeping, IPSAS adoption, GIFMIS implementation) that influence public funds management outcomes (budget credibility, expenditure arrears, audit irregularities, service delivery, public trust), and to propose evidence-based recommendations for strengthening public sector accounting to improve public funds management at federal, state, and local government levels.

1.4 Objectives of the Study

The specific objectives of this study are to:

1. Assess the current state of public sector accounting in Nigerian public sector entities (federal MDAs, state governments, local governments), including the adoption and implementation of IPSAS and GIFMIS.
2. Evaluate the effectiveness of public funds management outcomes as measured by budget credibility (budget implementation rates, variance between appropriated and actual expenditure), expenditure arrears (unpaid bills), audit irregularities (unauthorized expenditures, unsupported payments), and service delivery indicators.
3. Identify the specific weaknesses in the public sector accounting system that undermine public funds management: weak commitment control, lack of integration, poor internal controls, inadequate record keeping, and enforcement gaps.
4. Examine the relationship between GIFMIS implementation (coverage, functionality, staff training, system downtime, override frequency) and public funds management outcomes.
5. Compare public funds management effectiveness across levels of government (federal, state, local) and across sectors (education, health, infrastructure, administration).
6. Assess the role of internal and external audit in enforcing compliance with the accounting system and identifying irregularities.
7. Examine the influence of governance factors (political interference, corruption, capacity) on the effectiveness of public sector accounting.
8. Propose practical, evidence-based recommendations for strengthening public sector accounting to improve public funds management in Nigeria.

1.7 Significance of the Study

This study holds significance for multiple stakeholders as follows:

For the Office of the Accountant-General of the Federation (OAGF) and State Accountants-General:
The OAGF is responsible for the design and operation of the federal accounting system, including GIFMIS. The study provides evidence on the strengths and weaknesses of the current accounting system, enabling the OAGF to prioritize improvements. If GIFMIS is found to reduce irregularities, the OAGF can expand coverage. If staff training is found to improve outcomes, the OAGF can invest in training. The study also provides evidence for reporting to the Presidency and the National Assembly. State Accountants-General can use similar evidence for state-level reforms.

For the Auditor-General of the Federation and State Auditors-General:
Auditors rely on the accounting system to detect irregularities. The study provides evidence on which accounting system weaknesses are most associated with irregularities (e.g., weak commitment control, lack of integration). Auditors can use this evidence to target their audits, focusing on entities with weak accounting systems. The study also provides evidence for audit recommendations (e.g., strengthen commitment control, integrate systems).

For the National Assembly Public Accounts Committee (PAC) and State Legislatures:
The PAC is responsible for reviewing audit reports and holding MDAs accountable. The study provides evidence on systemic accounting weaknesses that require legislative action. For example, if the study finds that lack of integration between payroll and GIFMIS enables ghost workers, the PAC can recommend legislative mandating of integration. The study also provides evidence to assess the effectiveness of past legislative interventions.

For the Ministry of Finance, Budget and National Planning:
The Ministry is responsible for budget preparation, budget execution, and fiscal policy. The study provides evidence on public funds management challenges that limit budget implementation. If the accounting system is found to be weak, the Ministry can advocate for reforms and resources. The study also provides evidence for reporting to the President and the Federal Executive Council.

For State Governments and Local Governments:
State and local governments face severe public funds management challenges. The study provides evidence on which accounting system reforms (GIFMIS adoption, IPSAS adoption, internal control strengthening) are most effective. State governments can use this evidence to design reform programs and to request technical assistance from the federal government or development partners.

For Civil Society Organizations (BudgIT, Enough is Enough, TI-Nigeria):
CSOs advocate for transparency and accountability in public funds management. The study provides evidence on systemic weaknesses that CSOs can use in advocacy campaigns (e.g., “the accounting system is failing to manage public funds”). The study also provides evidence to assess the effectiveness of past advocacy efforts.

For International Development Partners (World Bank, IMF, DFID, EU):
Development partners have invested millions of dollars in public financial management reforms in Nigeria (GIFMIS, IPSAS, public expenditure tracking). The study provides evidence on whether these investments have been effective. If positive effects are found, development partners can continue similar support. If no effects are found, development partners can redesign their programs (e.g., focus more on enforcement, less on system design). The study also provides evidence for program evaluation.

For Academics and Researchers:
This study contributes to the literature on public financial management in developing economies. Most PFM research focuses on developed economies; this study provides evidence from Nigeria, a large, complex developing country. The study uses multiple methods (surveys, document analysis, case studies) and multiple levels (federal, state, local). The study tests theoretical frameworks (agency theory, institutional theory, stewardship theory, PFM theory) in a new context. The study provides a foundation for future research on public sector accounting and public funds management in other African countries.

For the Nigerian Citizen and Taxpayer:
Citizens pay taxes and deserve to know that their money is being managed wisely. The study provides evidence on whether the accounting system is effectively managing public funds. If weaknesses are identified, citizens can demand reform. If the system is found to be effective, citizens can have greater confidence. The study also provides evidence for citizen-led monitoring initiatives (e.g., tracking public funds at local government level).

For the Nigerian Economy:
Public expenditure accounts for 15-20% of GDP. Effective public funds management ensures that public resources are used to provide essential services (education, health, infrastructure), which supports economic growth and poverty reduction. Wasteful or fraudulent expenditure diverts resources from productive uses. By identifying how to strengthen public sector accounting to improve public funds management, this study contributes to better public expenditure outcomes and, ultimately, economic development.

1.8 Scope of the Study

The scope of this study is defined by the following parameters:

Content Scope: The study focuses on the impact of effective public sector accounting on public funds management in Nigeria. Specifically, it examines: (1) public sector accounting features (commitment control, budget control, internal controls, integration, record keeping, IPSAS adoption, GIFMIS implementation); (2) public funds management outcomes (budget credibility, expenditure arrears, audit irregularities, service delivery, public trust); (3) the role of internal and external audit; (4) governance factors (political interference, corruption, capacity); and (5) the COVID-19 pandemic period. The study does not examine revenue collection (taxes, non-tax revenue) except as it relates to funds management (e.g., cash management). The study does not examine public procurement processes in depth except as they relate to the accounting system.

Organizational Scope: The study covers three levels of government in Nigeria: federal (selected Ministries, Departments, and Agencies), state (selected state governments and their ministries), and local (selected local government areas). The study includes entities that have implemented GIFMIS (federal and some states) and those that have not (most local governments, some states). The study includes entities that have adopted IPSAS (federal, some states) and those that have not (most local governments, some states). The study excludes government-owned enterprises (e.g., NITDA, NIMC) that operate under private sector accounting standards.

Geographic Scope: The study covers Nigeria. For federal MDAs, the study includes those headquartered in Abuja (Federal Capital Territory). For state governments, the study includes four states: Lagos (South-West), Kano (North-West), Rivers (South-South), and Enugu (South-East), representing Nigeria’s geopolitical diversity. For local governments, the study includes selected LGAs within these states. Findings may be generalizable to other states not included, but caution is warranted.

Time Scope: The study covers the period 2015-2024, a ten-year period encompassing: (1) full GIFMIS implementation at federal level (from 2015); (2) the adoption of the 2016 National Policy on Public Financial Management; (3) the COVID-19 pandemic period (2020-2021); and (4) the post-pandemic recovery period (2022-2024). This time period enables analysis of trends in public funds management over time.

Theoretical Scope: The study is grounded in agency theory, stewardship theory, institutional theory, and public financial management theory. These theories provide the conceptual lens for understanding the relationship between public sector accounting and public funds management.

Methodological Scope: The study uses a mixed-methods design: (1) quantitative analysis of secondary data (audit reports, financial statements, budget execution reports, service delivery indicators); (2) surveys of accounting staff, internal auditors, and budget officers; (3) qualitative interviews with key informants (Accountant-General, Auditor-General, PAC members, development partners); and (4) case studies of selected MDAs to understand implementation challenges.

CHAPTER TWO: LITERATURE REVIEW

2.1 Introduction

This chapter presents a comprehensive review of literature relevant to the impact of effective public sector accounting on public funds management in Nigeria. The review is organized into five main sections. First, the conceptual framework section defines and explains the key constructs: public sector accounting, public funds management, IPSAS, GIFMIS, commitment control, budget credibility, and financial irregularities. Second, the theoretical framework section examines the theories that underpin the relationship between public sector accounting and public funds management, including agency theory, stewardship theory, institutional theory, and public financial management theory. Third, the empirical review section synthesizes findings from previous studies on public sector accounting and public funds management globally and in Nigeria. Fourth, the regulatory framework section examines the Nigerian context, including GIFMIS, IPSAS, the Fiscal Responsibility Act, and the role of the Auditor-General. Fifth, the summary of literature identifies gaps that this study seeks to address.

The purpose of this literature review is to situate the current study within the existing body of knowledge, identify areas of consensus and controversy, and justify the research questions and hypotheses formulated in Chapter One (Creswell and Creswell, 2018). By critically engaging with prior scholarship, this chapter establishes the intellectual foundation upon which the present investigation is built. (Creswell and Creswell, 2018)

2.2 Conceptual Framework

2.2.1 The Concept of Public Sector Accounting

Public sector accounting is a specialized branch of accounting that deals with the recording, classification, analysis, summarization, and reporting of financial transactions of government entities. Unlike private sector accounting, which focuses on profit measurement and wealth creation for shareholders, public sector accounting focuses on budgetary compliance, stewardship of public funds, accountability to citizens, and the efficient and effective use of public resources. The primary users of public sector accounting information include legislatures (for oversight), oversight bodies (Auditor-General, Public Accounts Committee), citizens (for accountability), creditors (for lending decisions), and international partners (for development assistance) (Premchand, 2017). (Premchand, 2017)

Public sector accounting operates within a legal and regulatory framework that includes constitutions, financial regulations, appropriation acts, and public financial management laws. The accounting basis can be cash (recording transactions only when cash is received or paid), modified cash (adding some accruals), modified accrual (adding most accruals but not all), or full accrual (recording all economic events, including non-cash transactions). Nigeria has committed to full accrual IPSAS, but implementation remains incomplete (IPSASB, 2022). (IPSASB, 2022)

The key components of a public sector accounting system include (Khan and Hildreth, 2019):

Chart of Accounts: A structured list of accounts used to classify financial transactions (e.g., by ministry, program, economic classification).

Budgeting Module: Tracks budget appropriations and actual expenditures against appropriations.

Commitment Control Module: Records commitments (purchase orders, contracts) before payments.

Cash Management Module: Tracks cash receipts and payments, manages bank accounts.

Accounts Payable: Records amounts owed to vendors and other creditors.

General Ledger: The central repository of all financial transactions.

Financial Reporting Module: Produces financial statements (monthly, quarterly, annual).

Asset Register: Records government assets (property, plant, equipment).

2.2.2 The Concept of Public Funds Management

Public funds management (also called public financial management, PFM) refers to the processes, systems, and controls used by governments to plan, allocate, monitor, and account for public financial resources. The ultimate goals of public funds management are fiscal discipline, allocative efficiency, and operational efficiency (Schick, 2018). (Schick, 2018)

Fiscal Discipline (Aggregate Control): Total expenditure does not exceed total revenue plus sustainable borrowing. This is the highest level of control, typically exercised by the Ministry of Finance through budget preparation and cash management. Indicators of fiscal discipline include budget credibility (actual expenditure close to budget) and low fiscal deficits.

Allocative Efficiency: Resources are allocated to strategic priorities in accordance with government policies. This level of control is exercised through the budget process and legislative approval. Indicators of allocative efficiency include alignment of budget with development plans and sectoral allocations.

Operational Efficiency: Resources are used to achieve outputs at minimum cost. This level of control is exercised by spending entities (MDAs) through internal controls, procurement systems, and performance management. Indicators of operational efficiency include low cost per output and high service delivery outcomes.

The public funds management cycle includes (World Bank, 2020):

1. Budget Preparation: Estimating revenues and expenditures for the coming fiscal year.
2. Budget Approval: Legislature reviews and approves the budget (Appropriation Act).
3. Budget Execution: Spending entities incur expenditures in accordance with appropriations.
4. Accounting and Reporting: Recording transactions and producing financial statements.
5. Audit and Oversight: Independent verification of compliance and performance.
6. Legislative Scrutiny: Public Accounts Committee reviews audit reports.

2.2.3 Commitment Control

Commitment control (also called encumbrance accounting) is a system that records commitments (purchase orders, contracts) before payments are made, ensuring that the government does not commit to spend more than is available. The commitment control process has three stages (Premchand, 2017). (Premchand, 2017)

Stage 1: Commitment. When a purchase order or contract is issued, a “commitment” is recorded against the budget. This reduces available appropriations, preventing over-commitment.

Stage 2: Obligation. When goods or services are received, the commitment is converted to an “obligation” (liability). This represents the amount legally owed.

Stage 3: Payment. When the invoice is paid, the obligation is extinguished, and cash is reduced.

Without commitment control, a government can commit to spend more than its budget allows because commitments are not tracked. For example, a ministry could issue purchase orders totaling ₦200 million when only ₦100 million is available. When the invoices arrive, the ministry cannot pay, creating arrears. Commitment control prevents this by checking each purchase order against available appropriations and rejecting orders that would exceed limits (Premchand, 2017). (Premchand, 2017)

GIFMIS includes commitment control functionality. However, studies have found that many Nigerian MDAs do not use commitment control effectively. Some MDAs do not record commitments in GIFMIS; others record commitments after payments (defeating the purpose). Strengthening commitment control is a priority for public funds management (Okoye, Okafor, and Nnamdi, 2020). (Okoye et al., 2020)

2.2.4 Budget Credibility

Budget credibility is the degree to which actual expenditure conforms to budgeted appropriations. High budget credibility means that actual expenditure does not deviate significantly from budget. Low budget credibility (high variance) indicates that the budget is not a reliable planning tool and that public funds are not being managed as intended (Schick, 2018). (Schick, 2018)

Budget credibility is measured by the variance between appropriated and actual expenditure. The International Monetary Fund (IMF) recommends that variance should not exceed 5% for aggregate expenditure and 15% for sectoral allocations. Many developing countries, including Nigeria, have much higher variances. In Nigeria, capital budget implementation averages 60-70% annually, meaning that 30-40% of appropriated capital funds are not spent as planned. This is often due to late release of funds, weak capacity, or procurement delays (BudgIT, 2023). (BudgIT, 2023)

Low budget credibility has negative consequences: (1) it reduces the effectiveness of planning (MDAs cannot rely on budgeted funds); (2) it undermines legislative oversight (legislature cannot hold executive accountable for deviations); (3) it reduces service delivery (funds are not available when needed); and (4) it erodes public trust. The accounting system contributes to budget credibility by providing timely information on budget execution and by enforcing commitment control (Schick, 2018). (Schick, 2018)

2.2.5 Financial Irregularities

Financial irregularities are violations of financial regulations, laws, or policies in the use of public funds. The Auditor-General of the Federation categorizes irregularities into several types (Auditor-General of the Federation, 2020). (Auditor-General of the Federation, 2020)

Unauthorized Expenditure: Expenditure incurred without appropriation by the National Assembly or without proper authorization. Section 80 of the Nigerian Constitution prohibits unauthorized expenditure.

Payment Without Supporting Documents: Payments made without invoices, receipts, delivery notes, or other evidence that goods or services were received.

Contract Award Without Due Process: Contracts awarded without competitive bidding, without approval from the Bureau of Public Procurement (BPP), or to ineligible contractors.

Non-Retirement of Advances: Funds advanced to staff or contractors for official purposes (e.g., travel, training) that are not accounted for with receipts and unspent balances not returned.

Overpayment: Payment of amounts exceeding what is due under contract or law.

Failure to Deduct or Remit Taxes: Failure to deduct Withholding Tax (WHT) or Value Added Tax (VAT) from payments, or failure to remit deducted taxes to FIRS.

Financial irregularities indicate that the accounting system is not effectively controlling public funds. Persistent irregularities suggest systemic weaknesses, not just isolated errors (Auditor-General of the Federation, 2020). (Auditor-General of the Federation, 2020)

2.2.6 Government Integrated Financial Management Information System (GIFMIS)

GIFMIS is an integrated computerized financial management information system used by the Nigerian Federal Government (and some state governments) to manage public finances. GIFMIS integrates budgeting, procurement, commitment control, payment processing, accounting, and reporting into a single system. The key modules of GIFMIS include (Federal Ministry of Finance, 2015). (Federal Ministry of Finance, 2015)

Budgeting Module: Supports budget preparation and approval, linking budget allocations to MDAs and activities.

Procurement Module: Supports the procurement process (contract awards, purchase orders) and integrates with commitment control.

Commitment Control Module: Records commitments and checks them against available appropriations.

Payment Module: Processes payments to vendors and employees, with workflow approval.

Accounting Module: Records transactions in the general ledger, produces financial statements.

Reporting Module: Generates budget execution reports, financial statements, and other reports.

Asset Module: Records government assets (property, plant, equipment).

GIFMIS was intended to strengthen public funds management by: (1) enforcing budget limits (system will reject transactions that exceed appropriations); (2) enforcing approval workflows (payments require multiple approvals); (3) creating an audit trail (every transaction is recorded); (4) providing real-time expenditure information; and (5) integrating financial systems (payroll, procurement, GIFMIS) (Federal Ministry of Finance, 2015). (Federal Ministry of Finance, 2015)

However, GIFMIS implementation has faced challenges: system downtime, lack of trained personnel, data entry errors, override abuse, and resistance from staff accustomed to manual processes. The effectiveness of GIFMIS in managing public funds has not been rigorously evaluated (Okoye et al., 2020). (Okoye et al., 2020)

2.3 Theoretical Framework

This section presents the theories that provide the conceptual lens for understanding the impact of effective public sector accounting on public funds management. Four theories are discussed: agency theory, stewardship theory, institutional theory, and public financial management theory.

2.3.1 Agency Theory

Agency theory, developed by Jensen and Meckling (1976), posits a conflict of interest between principals (citizens) and agents (government officials). Officials may pursue self-interest (corruption, patronage, empire building) rather than the public interest. This divergence creates agency costs, including monitoring costs (expenditures to oversee officials) and bonding costs (expenditures by officials to assure citizens). Public sector accounting is a monitoring mechanism that reduces agency costs by providing citizens and oversight bodies with information about official actions (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

Agency theory predicts that a strong accounting system (with commitment control, budget control, audit trail) will reduce information asymmetry, enabling citizens and legislators to monitor expenditure and detect irregularities. Weak accounting systems enable officials to hide unauthorized expenditures, fraud, and waste. The accounting system is not only a technical tool but also a governance mechanism that constrains official discretion (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

However, agency theory also recognizes that monitoring is costly and that officials may resist monitoring. GIFMIS implementation in Nigeria has faced resistance from officials accustomed to discretion. Override features in GIFMIS allow officials to bypass controls, reducing the system’s effectiveness. Agency theory predicts that the effectiveness of the accounting system depends on the incentives of officials: if officials are penalized for irregularities, they will comply; if irregularities go unpunished, they will circumvent controls (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

2.3.2 Stewardship Theory

Stewardship theory, developed by Donaldson and Davis (1991), offers an alternative to agency theory. Stewardship theory argues that government officials are inherently motivated to act in the best interests of citizens because they derive satisfaction from achieving organizational goals and acting as responsible stewards. Unlike agency theory’s assumption that monitoring is necessary, stewardship theory suggests that officials will act responsibly when empowered and trusted (Donaldson and Davis, 1991). (Donaldson and Davis, 1991)

From a stewardship perspective, public sector accounting is not primarily a monitoring mechanism but an enabling tool that helps officials manage public funds effectively. Officials who are motivated to be good stewards will use the accounting system to track expenditures, control budgets, and report transparently. The accounting system provides information that officials need to make informed decisions (Donaldson and Davis, 1991). (Donaldson and Davis, 1991)

Stewardship theory suggests that improving public funds management requires not only strengthening the accounting system but also fostering a culture of stewardship (integrity, accountability, public service motivation). Training, ethics codes, and leadership can promote stewardship. In the Nigerian context, however, the prevalence of corruption suggests that stewardship theory may be less descriptive than agency theory (Donaldson and Davis, 1991). (Donaldson and Davis, 1991)

2.3.3 Institutional Theory

Institutional theory, developed by DiMaggio and Powell (1983), argues that organizations adopt practices not only for their economic benefits but also because of institutional pressures: coercive pressures (legal requirements), mimetic pressures (copying successful organizations), and normative pressures (professional norms). Organizations adopt practices to gain legitimacy, which is essential for survival (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

In the context of public funds management, institutional theory suggests that accounting systems (GIFMIS, IPSAS) are adopted not only to improve funds management but also to gain legitimacy with international partners (World Bank, IMF) and citizens. Governments adopt modern accounting systems to signal that they are modern, transparent, and accountable. However, adoption may be “decoupled” from actual practice: governments may adopt the system on paper but not use it effectively (decoupling) (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

In Nigeria, evidence of decoupling includes: GIFMIS implemented but not fully used; IPSAS adopted but not fully implemented; audit reports documenting irregularities year after year without corrective action. Institutional theory predicts that decoupling is more likely when enforcement is weak. This study examines whether decoupling is prevalent in Nigeria (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

2.3.4 Public Financial Management (PFM) Theory

Public Financial Management (PFM) theory, articulated by Schick (2018) and Allen, Schiavo-Campo, and Garrity (2004), provides a framework for understanding public funds management. PFM theory identifies three core objectives: (1) aggregate fiscal discipline (total expenditure does not exceed total revenue plus sustainable borrowing); (2) allocative efficiency (resources are allocated to strategic priorities); and (3) operational efficiency (resources are used to achieve outputs at minimum cost) (Schick, 2018). (Schick, 2018)

PFM theory identifies key institutions and processes for achieving these objectives: (1) a credible budget; (2) a treasury single account (TSA) for cash management; (3) commitment control; (4) internal controls; (5) accounting and reporting; (6) internal audit; (7) external audit; and (8) legislative oversight. The accounting system is central to all these processes (Allen et al., 2004). (Allen et al., 2004)

PFM theory also recognizes that PFM reforms must be adapted to country context. What works in developed economies may not work in developing economies with weak capacity, corruption, and political interference. The effectiveness of GIFMIS in Nigeria depends on Nigeria’s capacity to implement and enforce it (Allen et al., 2004). (Allen et al., 2004)

2.4 Empirical Review

This section reviews empirical studies that have examined the relationship between public sector accounting and public funds management. The review is organized thematically: global studies, African studies, Nigerian studies, and studies on GIFMIS and IPSAS.

2.4.1 Global Studies

In developed economies, public funds management is generally strong. Diamond (2013) studied the effect of commitment control on expenditure outcomes in 20 OECD countries. Using panel data from 1995-2010, he found that countries with robust commitment control systems (recording commitments before payments) had significantly lower expenditure overruns (mean 2.3% vs. 5.1% of budget, p < 0.01). The study concluded that commitment control is the most important accounting system feature for public funds management. (Diamond, 2013)

In the United States, Lienert (2015) examined the relationship between integrated financial management systems (IFMIS) and budget execution. Using case studies of six states, he found that IFMIS adoption reduced unauthorized expenditures by 60% and reduced late payments by 70%. However, benefits were only realized when: (1) systems were fully implemented (not just installed); (2) staff were trained; (3) management enforced compliance; and (4) auditors monitored. (Lienert, 2015)

In the United Kingdom, the National Audit Office (2018) evaluated the effectiveness of the government’s integrated financial management system. The NAO found that the system reduced errors, improved timeliness of reporting, and strengthened audit trails. However, the NAO also found that manual overrides of system controls were a persistent problem, and recommended reducing override authority. (National Audit Office, 2018)

2.4.2 African Studies

In developing economies, the relationship between public sector accounting and public funds management is more complex. Dorotinsky and Pradhan (2007) studied IFMIS implementation in 30 developing countries (including African countries). They found that only 30% of IFMIS projects were successful in improving public funds management; 40% were partially successful; and 30% failed. Success factors included: political commitment, adequate funding, technical capacity, change management, and enforcement. Failure was associated with: lack of commitment, underfunding, resistance from staff, and overrides of controls. (Dorotinsky and Pradhan, 2007)

In Ghana, Amoako and Asante (2018) examined the effect of the Ghana Integrated Financial Management Information System (GIFMIS) on public funds management. Using a sample of 50 MDAs over 5 years, they found that GIFMIS reduced unauthorized expenditures by 40% and reduced payment delays by 50%. However, the effect was smaller in MDAs with weak internal controls and where political interference was high. They concluded that technology alone is not sufficient; organizational factors matter. (Amoako and Asante, 2018)

In Kenya, Ochieng and Wamukoya (2019) evaluated the Integrated Financial Management Information System (IFMIS). They found that IFMIS improved commitment control (reduced expenditure overruns) but did not reduce unauthorized expenditures (payments without approval). The latter persisted because of overrides: officials could bypass IFMIS controls with management approval. They recommended reducing override authority and strengthening audit. (Ochieng and Wamukoya, 2019)

2.4.3 Nigerian Studies

Several Nigerian studies have examined aspects of public sector accounting and public funds management. Okoye, Okafor, and Nnamdi (2020) evaluated GIFMIS implementation in 30 federal MDAs. Using surveys and document analysis, they found that: (1) 65% of MDAs used GIFMIS for payments; (2) 45% used GIFMIS for commitment control (recording purchase orders); (3) 35% used GIFMIS for budget control (tracking expenditure against appropriations); (4) 70% reported system downtime as a major challenge; (5) 55% reported lack of trained staff; and (6) 40% reported that officials sometimes override system controls. They concluded that GIFMIS has improved public funds management but that significant challenges remain. (Okoye et al., 2020)

Adeyemi and Ogundipe (2020) examined the relationship between IPSAS adoption and financial reporting quality in Nigerian state governments. Using a sample of 20 state governments over 6 years, they found that IPSAS adoption was associated with: (1) reduced audit irregularities (mean -25%, p < 0.05); (2) improved timeliness of reporting (reduced delay from 18 months to 12 months, p < 0.05); and (3) improved transparency (more disclosures). However, the effect varied across states: states with stronger governance (e.g., economic planning commissions) had larger improvements. (Adeyemi and Ogundipe, 2020)

Auditor-General of the Federation (2020) documented the extent of financial irregularities in federal MDAs. Key findings: ₦50 billion in unauthorized expenditures; ₦45 billion in payments without supporting documents; ₦30 billion in contract awards without due process; and ₦20 billion in non-retirement of advances. The Auditor-General noted that these irregularities persist despite GIFMIS, indicating that GIFMIS is not being used effectively or that controls are being overridden. (Auditor-General of the Federation, 2020)

Ogunyemi and Adewale (2021) examined public funds management during COVID-19. Using a sample of 20 MDAs that received COVID-19 funds, they found that: (1) 45% of MDAs did not record commitments before payments; (2) 35% made payments without proper approval; (3) 30% failed to retain supporting documents; and (4) 25% did not reconcile bank accounts. The study concluded that the accounting system failed to manage COVID-19 funds, enabling waste and fraud. (Ogunyemi and Adewale, 2021)

BudgIT (2023) analyzed state government public funds management using budget implementation reports. Key findings: (1) capital budget implementation averages 50-60% annually; (2) variance between budgeted and actual expenditure is high (30-40%); (3) many states do not publish quarterly budget implementation reports; (4) audit reports show persistent irregularities. The study concluded that state governments have weaker accounting systems than the federal government. (BudgIT, 2023)

2.4.4 Factors Affecting Public Sector Accounting Effectiveness

Several factors moderate the relationship between public sector accounting and public funds management. Staff capacity is a key factor. Dorotinsky and Pradhan (2007) found that IFMIS projects were more successful in countries with higher technical capacity. In Nigeria, Okoye et al. (2020) found that 55% of MDAs lacked trained GIFMIS staff, and that staff capacity was positively associated with system use (r = 0.48, p < 0.01). (Dorotinsky and Pradhan, 2007; Okoye et al., 2020)

Management commitment is another factor. Khan (2016) found that MDAs with strong management commitment to public funds management had 60% fewer irregularities than those with weak commitment. In Nigeria, Adeyemi and Ogundipe (2020) found that states with strong political commitment (e.g., creation of state economic planning commissions) had better IPSAS implementation. (Adeyemi and Ogundipe, 2020; Khan, 2016)

Audit and enforcement are critical. Lienert (2015) found that IFMIS effectiveness was higher when internal and external audits were strong. In Nigeria, the Auditor-General (2020) noted that audit recommendations are rarely implemented, undermining enforcement. (Auditor-General of the Federation, 2020; Lienert, 2015)

Political interference can undermine accounting systems. Ochieng and Wamukoya (2019) found that political interference (e.g., ministers ordering payments without IFMIS approval) was a major cause of public funds management failures in Kenya. In Nigeria, Ogunyemi and Adewale (2021) found similar evidence during COVID-19. (Ochieng and Wamukoya, 2019; Ogunyemi and Adewale, 2021)

2.5 Regulatory Framework in Nigeria

This section outlines the key regulatory provisions governing public sector accounting and public funds management in Nigeria.

Constitution of the Federal Republic of Nigeria (1999 as amended): Sections 80-83 govern public expenditure. Section 80 requires that no expenditure be incurred without appropriation by the National Assembly. Section 81 requires the President to submit annual budgets. Section 82 regulates virement (transfer of funds). Section 83 regulates supplementary budgets.

Fiscal Responsibility Act (2007): The Act establishes the Fiscal Responsibility Commission (FRC) to enforce fiscal discipline. It requires that government budgets be based on realistic revenue and expenditure estimates, and that expenditure be controlled to prevent fiscal deficits.

Public Procurement Act (2007): The Act establishes the Bureau of Public Procurement (BPP) to regulate procurement. It requires that procurement be conducted through competitive bidding, that contracts be awarded with due process, and that procurement be integrated with the accounting system.

Financial Reporting Council (FRC) of Nigeria Act (2011): The Act established the FRC to set accounting standards (including IPSAS) and to ensure compliance with financial reporting standards.

Treasury Single Account (TSA) Policy (2015): The TSA requires that all government revenues be deposited into a single bank account and that all payments be made from that account. The TSA improves cash management and expenditure control.

Government Integrated Financial Management Information System (GIFMIS) Implementation Framework (2012): The framework sets out the policies and procedures for GIFMIS implementation, including: (1) mandatory use of GIFMIS for all MDAs; (2) commitment control; (3) budget control; (4) approval workflows; and (5) audit trail requirements.

2.6 Summary of Literature Gaps

The review of existing literature reveals several significant gaps that this study seeks to address.

Gap 1: Limited Nigerian-specific evidence on the impact of public sector accounting on public funds management. While several studies have described GIFMIS or documented irregularities, few have systematically analyzed the causal relationship between accounting system features (commitment control, budget control, integration) and public funds management outcomes (budget credibility, irregularities, service delivery). This study addresses this gap.

Gap 2: Lack of comparative analysis across levels of government. Most Nigerian studies focus on federal MDAs. State and local governments (50% of public expenditure) have weaker accounting systems and different public funds management challenges. This study includes federal, state, and local levels.

Gap 3: Limited examination of GIFMIS implementation quality (vs. adoption). Most studies treat GIFMIS as binary (implemented vs. not). However, implementation quality (staff training, system functionality, override frequency) varies. This study examines implementation quality as a variable.

Gap 4: Lack of research on the role of overrides in undermining public funds management. GIFMIS has override features; it is unknown how frequently overrides are used, for what purposes, and whether they are justified. This study examines override patterns.

Gap 5: Limited examination of political interference as a moderating factor. Studies have noted political interference but have not systematically measured it or tested its moderating effect. This study includes political interference as a variable.

Gap 6: No study has examined the relationship between internal audit quality and GIFMIS compliance. Internal audit is supposed to enforce compliance, but its effectiveness is unknown. This study examines this relationship.

Gap 7: Limited research on COVID-19 public funds management. The pandemic created a stress test for accounting systems. No Nigerian study has systematically analyzed COVID-19 public funds management outcomes. This study includes COVID-19 period data.

Gap 8: Lack of integration of multiple data sources. Most studies rely on a single data source (audit reports or surveys). This study combines audit reports, financial statements, surveys of accounting staff, interviews with key informants, and case studies.

Gap 9: Limited use of theoretical frameworks. Many Nigerian studies are descriptive, lacking theoretical grounding. This study is grounded in agency theory, stewardship theory, institutional theory, and PFM theory.

Gap 10: Insufficient attention to local government public funds management. Local governments are the level closest to citizens, but their accounting systems are the weakest. No Nigerian study has focused on local government public funds management. This study fills this gap.
