Abstract
This research investigates the relationship between external debt and economic growth in Nigeria from 1981 to 2010. External debt has been a major concern for many developing countries, as it can have both positive and negative impacts on economic growth. The study employs quantitative analysis using time series data to examine the effect of external debt on Nigeria's economic growth over a 30-year period. The findings suggest a complex relationship between external debt and economic growth in Nigeria during the study period. The results reveal that there is a significant negative impact of external debt on economic growth in the short run, indicating that increased borrowing from external sources can hinder economic growth in the immediate term. However, in the long run, the relationship becomes less clear, with some evidence suggesting that external debt may have a positive effect on economic growth after a certain threshold. Furthermore, the study considers other factors that may influence the relationship between external debt and economic growth, such as inflation, exchange rate fluctuations, and government policies. By controlling for these variables, the research provides a more nuanced understanding of the dynamics at play in Nigeria's economy during the period under investigation. Overall, the findings of this study contribute to the ongoing debate on the impact of external debt on economic growth in developing countries like Nigeria. The results highlight the importance of carefully managing external debt levels to ensure sustainable economic growth. Policymakers in Nigeria can use these findings to inform their decisions on borrowing and debt management strategies, taking into account the potential risks and benefits associated with external debt. The research also underscores the need for further investigation into the specific mechanisms through which external debt affects economic growth in Nigeria. By deepening our understanding of these relationships, policymakers can develop more effective strategies to promote long-term economic development and stability in the country.

Thesis Overview

INTRODUCTION
1.0 BACKGROUND OF THE STUDY
It is generally expected that developing countries, facing a scarcity of capital, will acquire external debt to supplement domestic saving (Malik et al, 2010; Aluko and Arowolo, 2010). Besides, external borrowing is preferable to domestic debt because the interest rates charged by international financial institutions like International Monetary Funds (IMF) is about half to the one charged in the domestic market (Pascal, 2010). However, whether or not external debt would be beneficial to the borrowing nation depends on whether the borrowed money is used in the productive segments of the economy or for consumption. Adepoju et al (2007) stated that debt financed investment need to be productive and well managed enough to earn a rate of return higher than the cost of debt servicing
The main lesson of the standard “growth with debt” literature is that a country should borrow abroad as long as the capital thus acquired produces a rate of return that is higher than the cost of the foreign borrowing. In that event, the borrowing country is increasing capacity and expanding output with the aid of foreign savings. The debt, if properly utilised, is expected to help the debtor country’s economies (Hameed et al, 2008) by producing a multiplier effect which leads to increased employment, adequate infrastructural base, a larger export market, improved exchange rate and favourable terms of trade. But, this has never been the case in Nigeria and several other sub-Saharan African Countries (SSA) where it has been misused (Aluko and Arowolo, 2010). Apart from the fact that external debt had been badly expended in these countries, the management of the debt by way of service payment, which is usually in foreign exchange, has also affected their macroeconomic performance (Aluko and Arowolo, (2010); Serieux and Yiagadeesen, (2001).
Prior to the $18 billion debt cancellation granted to Nigeria in 2005 by the Paris Club, the country had external debt of close to $40 billion with over $30 billion of the amount being owed to Paris Club alone (Semenitari, 2005a). The history of Nigeria’s huge debts can hardly be separated from its decades of misrule and the continued recklessness of its rulers. Nigeria’s debt stock in 1971 was $1 billion (Semenitari, 2005a). By 1991, it had risen to $33.4 billion, and rather than decrease, it has been on the increase, particularly with the insurmountable regime of debt servicing and the insatiable desire of political leaders to obtain loans for the execution of dubious projects (Semenitari, 2005a).
Before the debt cancellation deal, Nigeria was to pay a whopping sum of $4.9 billion every year on debt servicing (Aluko and Arowolo, 2010). It would have been impossible to achieve exchange rate stability or any meaningful growth under such indebtedness. The effect of the Paris Club debt cancellation was immediately observed in the sequential reduction of the exchange rate of Nigeria vis-à-vis the Dollar from 130.6 Naira in 2005 to 128.2 Naira in 2006, and then 120.9 in 2007 (CBN, 2009). Although the growth rate of the economy has been inconsistent in the post-debt relief period as it plunged from 6.5% in 2005 to 6% in 2006 and then increased to 6.5% in 2007 (CBN, 2008), it could have been worse if the debt had not been cancelled.

However, the benefits of the debt cancellation, which was expected to manifest after couple of years, was wiped up in 2009 by the global financial and economic crisis, which was precipitated in August 2007 by the collapse of the sub-prime lending market in the United States. The effect of the crisis on Nigeria’s exchange rate was phenomenal as the Naira exchange rate vis-à-vis the Dollar rose astronomically from about N120/$ in the last quarter of 2007 to more than N150/$ (about 25% increase) in the third quarter of 2009 (CBN, 2009). This is attributable to the sharp drop in foreign earnings of Nigeria as a result of the persistent fall of crude oil price, which plunged from an all-time high of US$147 per barrel in July 2007 to a low of US$45 per barrel in December 2008 (CBN, 2008).
Available statistics show that the external debt stock of Nigeria has been on the increase after the debt cancellation in 2005. The country’s external debt outstanding increased from $3,545 million in 2006 to $3,654 million in 2007, and then to $3,720 million and $3,947 in 2008 and 2009 respectively (CBN, 2009). It is therefore imperative to examine the effect of external debt of the country on her economy for us to appreciate the need to avoid being back in the group of highly indebted nations.
1.1 STATEMENT OF THE PROBLEM
The huge external debt stock and debt service payments of African countries and Nigeria in particular prevented the countries from embarking on larger volume of domestic investment, which would have enhanced growth and development (Clements, etal. 2003). External debt became a burden to most African countries because contracted loans were not optimally deployed, therefore returns on investments were not adequate to meet maturing obligations and did not leave a favourable balance to support domestic

economic growth. So, African economies have not performed well because the necessary macro-economic adjustment has remained elusive for most of the countries in the continent. The main interest of this study then is to empirically investigate the effect of external debt on the economic growth of Nigeria.
1.2 OBJECTIVES OF THE STUDY
The study will focus on the following objectives:
(i) Empirically investigate the effect of external debt on the growth process of the country;
(ii) To determine the impact of external debt service payment on economic growth of Nigeria.
1.3 STATEMENT OF HYPOTHESIS
HYPOTHESIS I
The following hypotheses are tested in this study:
Ho: That the external debt stock does not have impact on the economicgrowth of Nigeria.
HYPOTHESIS II
Ho: That the external debt service payment does not have an impact on economic growth of Nigeria.
1.4 SIGNIFICANCE OF THE STUDY
This study is focused on providing alternative measures to tackling external debt management problems. It will also serve as a tool in revamping government policies towards loan procurement and debt servicing in Nigeria. This work may also serve as a yardstick for further research and documentation on Nigeria’s external debt crisis.

1.5 SCOPE AND LIMITATIONS OF THE STUDY
The scope of this study shall cover the external debt trend of Nigeria over the years to date. The general overview of the debt cancellation shall be taken with certain issues raised and discussed.However, the empirical investigation of the effect of external debt on the economic growth of Nigeria shall be restricted to 1981 and 2010
