The Effectiveness of Macroeconomic Policies in Promoting Economic Growth in Nigeria
AIM AND OBJECTIVES OF THE STUDY
In the literature of macroeconomic theory, some serious prepositions have been made as to the effectiveness or otherwise of macroeconomic policy especially in the developing countries like Nigeria. In view of this, the aim of this study is to assess the effectiveness of macroeconomic policy in promoting economic growth in Nigeria. The objectives are;
- To highlight the extent to which money supply affect the Gross Domestic Product (GDP)
- To asses the macroeconomic policies put in place in Nigerian economy from 1993-2010; to see if it has any positive or negative effects on the Nigerian economy.
- To evaluate the effect of major macroeconomic variable on the Gross Domestic Product (GDP).

REVIEW OF RELATED LITERATURE
Macroeconomic Policies
Macroeconomic policies refer to the broad strategies and actions employed by governments and central banks to influence the performance and stability of an economy. These policies are primarily categorized into monetary policy and fiscal policy, though other supportive tools such as exchange rate policy and trade policy also play significant roles. The overarching objective of macroeconomic policy is to achieve sustainable economic growth, price stability, full employment, and a stable balance of payments (Mankiw, 2021).
Monetary policy involves the regulation of the money supply and interest rates by the central bank to influence inflation, consumption, investment, and overall economic activity. In Nigeria, the Central Bank of Nigeria (CBN) is responsible for implementing monetary policy. According to CBN (2023), its monetary policy framework is aimed at achieving price stability, curbing inflation, and promoting a stable financial system.
Fiscal policy, on the other hand, involves government decisions on taxation and public expenditure to influence the level of aggregate demand in the economy. Expansionary fiscal policy (increased government spending or reduced taxation) is often used to stimulate growth during a recession, while contractionary fiscal policy is used to control inflation (Iyoha, Oyefusi & Oriakhi, 2020).
In recent years, Nigeria has adopted a blend of fiscal and monetary measures to stabilize the economy. The implementation of the National Development Plan 2021–2025 underscores the importance of coordinated macroeconomic policies in addressing key developmental challenges such as unemployment, inflation, and low productivity (Federal Ministry of Finance, Budget and National Planning, 2021). For instance, the CBN’s use of tightening monetary policy to combat inflation and the federal government’s investment in infrastructure through fiscal stimulus are part of these efforts.
Scholars argue that for macroeconomic policies to be effective, there must be a synergy between monetary and fiscal policies. When these policies are poorly coordinated, they may counteract each other and hinder economic progress (Adeniran, Yusuf & Adedeji, 2022). Moreover, structural issues such as corruption, low revenue base, and policy inconsistency often limit the effectiveness of macroeconomic policies in developing economies like Nigeria.
Furthermore, macroeconomic stability is considered a prerequisite for long-term economic growth. Empirical evidence suggests that countries with stable inflation rates, prudent fiscal management, and responsive monetary policy frameworks tend to experience higher and more sustainable growth rates (World Bank, 2023).
Macroeconomic policies are vital tools for managing the economy. Their success in promoting economic growth in Nigeria depends not only on their design but also on effective implementation, institutional capacity, and consistency.
Fiscal Policy
Fiscal policy refers to the use of government revenue generation (mainly through taxation) and public expenditure to influence a country’s economic activity. It is a core component of macroeconomic policy, primarily aimed at stabilizing the economy, promoting growth, reducing unemployment, and managing inflation (Mankiw, 2021).
Governments implement expansionary fiscal policy by increasing public spending or reducing taxes to stimulate economic growth, especially during periods of recession. Conversely, contractionary fiscal policy involves decreasing government spending or increasing taxes to reduce inflationary pressures and stabilize the economy (Blanchard, 2022).

RESEARCH METHODOLOGY
INTRODUCTION
In this chapter, we described the research procedure for this study. A research methodology is a research process adopted or employed to systematically and scientifically present the results of a study to the research audience viz. a vis, the study beneficiaries.
RESEARCH DESIGN
Research designs are perceived to be an overall strategy adopted by the researcher whereby different components of the study are integrated in a logical manner to effectively address a research problem. In this study, the researcher employed the survey research design. This is due to the nature of the study whereby the opinion and views of people are sampled. According to Singleton & Straits, (2009), Survey research can use quantitative research strategies (e.g., using questionnaires with numerically rated items), qualitative research strategies (e.g., using open-ended questions), or both strategies (i.e., mixed methods). As it is often used to describe and explore human behaviour, surveys are therefore frequently used in social and psychological research.
POPULATION OF THE STUDY
According to Udoyen (2019), a study population is a group of elements or individuals as the case may be, who share similar characteristics. These similar features can include location, gender, age, sex or specific interest. The emphasis on study population is that it constitutes of individuals or elements that are homogeneous in description.
This study was carried to examine the effectiveness of macroeconomic policies in promoting economic growth in Nigeria. CBN staff in Anambra state form the population of the study.

DATA PRESENTATION AND ANALYSIS
INTRODUCTION
This chapter presents the analysis of data derived through the questionnaire and key informant interview administered on the respondents in the study area. The analysis and interpretation were derived from the findings of the study. The data analysis depicts the simple frequency and percentage of the respondents as well as interpretation of the information gathered. A total of eighty (80) questionnaires were administered to respondents of which only seventy-seven (77) were returned and validated. This was due to irregular, incomplete and inappropriate responses to some questionnaire. For this study a total of 77 was validated for the analysis.

SUMMARY, CONCLUSION AND RECOMMENDATION
Introduction
It is important to ascertain that the objective of this study was to ascertain the effectiveness of macroeconomic policies in promoting economic growth in Nigeria. In the preceding chapter, the relevant data collected for this study were presented, critically analyzed and appropriate interpretation given. In this chapter, certain recommendations made which in the opinion of the researcher will be of benefits in the effectiveness of macroeconomic policies in promoting economic growth in Nigeria
Summary
This study was on the effectiveness of macroeconomic policies in promoting economic growth in Nigeria. Three objectives were raised which included: To highlight the extent to which money supply affect the Gross Domestic Product (GDP), to asses the macroeconomic policies put in place in Nigerian economy from 1993-2010; to see if it has any positive or negative effects on the Nigerian economy and to evaluate the effect of major macroeconomic variable on the Gross Domestic Product (GDP). A total of 77 responses were received and validated from the enrolled participants where all respondents were drawn from CBN in Awka, Anamabra state. Hypothesis was tested using Chi-Square statistical tool (SPSS).
Conclusion
This study critically examined the effectiveness of macroeconomic policies particularly fiscal and monetary policies in promoting economic growth in Nigeria. Drawing from theoretical perspectives and empirical evidence, it is evident that both fiscal and monetary tools play a crucial role in shaping the country’s macroeconomic environment. Government spending, taxation, interest rates, money supply, and exchange rate management directly impact investment, employment, inflation, and output levels.
However, the Nigerian experience reveals that the implementation of macroeconomic policies has been marred by numerous challenges, including policy inconsistency, poor coordination between fiscal and monetary authorities, high dependence on oil revenue, inflationary pressures, exchange rate volatility, and weak institutional capacity. While capital expenditure and money supply have shown positive effects on growth, recurrent expenditure, inefficient tax systems, and monetary tightening often undermine these gains.
Recommendations
The Federal Ministry of Finance and the Central Bank of Nigeria should establish a formal framework for continuous policy dialogue and coordination to ensure fiscal and monetary policies are aligned toward common macroeconomic goals.
Government should reduce recurrent expenditure and increase capital investment in productive sectors such as infrastructure, education, health, and technology, which have greater multiplier effects on economic growth.
To reduce over-reliance on oil revenue, the government should reform the tax system to increase compliance, eliminate loopholes, and improve efficiency in tax administration. This includes expanding the non-oil tax base and digitalizing revenue collection systems.
The Central Bank should adopt clear inflation targeting frameworks and communicate its policy intentions effectively to enhance credibility and investor confidence, while ensuring that interest rates support productive investment.
The government should allow market-driven exchange rate mechanisms with limited intervention and develop non-oil exports to increase foreign exchange earnings and reduce dependence on imports.
