Project Abstract

Abstract
This research study examines the relationship between external debt and economic growth in Nigeria from 1981 to 2010. The issue of external debt has been a significant concern for many developing countries, including Nigeria. The accumulation of external debt can have both positive and negative effects on a country's economy, making it crucial to understand the specific impact it has on economic growth. Using time series data from 1981 to 2010, this study employs the autoregressive distributed lag (ARDL) approach to cointegration analysis to investigate the long-run relationship between external debt and economic growth in Nigeria. The study also considers other key variables such as foreign direct investment (FDI), government expenditure, and trade openness to provide a comprehensive analysis of the factors influencing economic growth. The findings suggest a mixed impact of external debt on economic growth in Nigeria during the period under study. The results show that while external debt initially had a positive effect on economic growth, this effect diminished over time and eventually turned negative. This indicates that the accumulation of external debt beyond a certain threshold can hinder economic growth in Nigeria. Furthermore, the study finds that foreign direct investment (FDI) has a positive and significant impact on economic growth in Nigeria. This suggests that FDI inflows can help stimulate economic growth and offset the negative effects of external debt. Government expenditure is also found to have a positive impact on economic growth, highlighting the importance of strategic public spending in promoting economic development. Trade openness is another crucial factor influencing economic growth in Nigeria, with the results indicating a positive relationship between trade openness and economic growth. This underscores the importance of international trade in driving economic growth and development in Nigeria. Overall, this study contributes to the ongoing debate on the impact of external debt on economic growth in developing countries like Nigeria. The findings suggest that while external debt can initially boost economic growth, excessive debt accumulation can have detrimental effects. Policymakers in Nigeria should therefore carefully manage external debt levels and focus on attracting foreign direct investment, increasing government expenditure in strategic areas, and promoting trade openness to foster sustainable economic growth.

Project 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.
