ABSTRACT
The research is on Assessing the Effect of Oil Dependency on Nigeria’s Economic growth. The main objective of this study is to examine the relationship between oil dependency and the Nigeria’s economy. Data for this research were obtained from secondary sources. Data analyses were done through the use of Unit Root Test, Johanson Co-integration test and Vector Auto Regressive Model. Hypotheses were tested through Granger Causality Test.
The major findings of this study are as follows:
Overdependence on oil revenue has more positive impact than negative impact on Nigeria’s economic growth.
Agriculture, Tourism, Taxation & Solid minerals are factors that could minimize Nigeria’s overdependence on oil revenue.
On the basis of the above findings, the study concludes that Nigerian economic growth is highly depended on the oil revenue. Hence, if there is a glut and fall in oil price in international market, it may be a great disaster on the economy and to the citizenry of the country.
From the findings of this study, the following are recommendations:
The Nigerian government should focus on the need for diversification into other sources of revenue in order not to be affected by fall of oil price in the international market.
The government should develop other sectors of the economy such as agricultural sector, and industrial sector by providing incentives such as tax concession, provision of facilities needed by these sectors in order to boost more production.

CHAPTER ONE
INTRODUCTION
1.0 Background of the study
Nigeria
is a natural resource rich country inhabited by an estimated 167 million people
and a land area of around 924 thousand square kilometer. It is situated in West
Africa surrounded by Cameroon to the east, Benin to the west, Niger to the
north and Gulf of Guinea to the South. It is considered the second largest
economy in Africa1 and largest oil producer in Africa (OPEC 2012). The country’s primary productive base
includes the production of agriculture, crude oil and other hydrocarbons and is
said to account for more than 90 per cent of foreign exchange and 75 per cent
of employment (Nigerian National Petroleum Corporation 2012). In the last five
years, Nigeria’s economy grew by an average of 7 per cent2 and is primarily
driven by the oil sector which accounts for more than 30 per cent of gross
domestic product and 70 per cent of all exports. According to Organisation for
Economic Co-operation and Development, in 2011, mining and quarrying (including
oil) accounted for 33.5 per cent of total GDP. Despite the oil sector’s
dominance, agriculture is also an important contributor to the economy
accounting for 35.2 per cent of GDP in 2011(OECD 2012).
In
the last five years, GDP has shown very impressive growth with a growth rate of
7.43 per cent in December 2011 and 6 per cent in 2012 (FSDH 2002).
This
growth rate makes Nigeria one of the fastest growing economies in the world
despite the lack of infrastructure and economic development. While oil and
agriculture are the primary contributors to the increased growth, the nonoil
sector including telecommunications has showed explosive growth (FSDH 2).
Nevertheless, oil continues to account for more than 85 per cent of all exports
each year. In 2011, fuel exports were 89 per cent of all merchandise exports.
And as Figure 2 illustrates, fuel rents have remained noticeably high and
volatile. As an oil dependent country, the volatility of the oil sector greatly
affects Nigeria’s government revenue which coincidently determines the extent
of the fiscal policy.
With
Nigeria’s rapid growth currently becoming stagnant at around 7 per cent and oil
prices which continue to be volatile, there is much discussion on the topic of
what can be done to ensure continuous growth regardless of the global market.
This volatility has come from international shocks caused by financial crises,
strikes, wars and decreased oil production. It is because of this volatility in
oil prices and Nigeria’s dependence on oil that many economists raise concern
about the future of the economy. As alternative fuels become more popular and
oil importing countries continue to discover oil deposits, there is a need for
the Nigerian economy to look to other, more manageable sources of foreign
exchange and government revenue to spur economic growth.
1.1 Problem Statement and
Justification
It
is estimated that Nigeria has 37.2 billion barrels of oil reserves (as of 2011)
and produces an average of 2.13 million barrels per day (EIA 2013). The
hydrocarbon sector also accounts for more than 75 per cent of the federal
government’s revenue. This suggests that Nigeria is heavily dependent on the
oil sector for the majority of government spending, infrastructure and most
economic development activities. With the increasing volatility of oil prices,
the discovery of oil in other parts of the world and the instability of the
global economy, oil imports from Nigeria to major economies such as the United
States has steadily decreased. The U.S once imported 9-11% of its crude oil
from Nigeria but in the first half of 2012, the share of imported oil from
Nigeria to the U.S has dropped to 5% (EIA 2013). The resource based growth
strategy followed by Nigeria and many developing countries with an abundance of
natural resources appear to not be working. Most Latin American and African
countries still struggle to develop, while developed countries follow industrialization
strategies which have led to economic growth. The issue of Nigeria’s oil
dependency is closely related to that of globalization and commodity prices.
While globalization is inevitable, Nigeria and other such countries must find
ways to protect its economy from the global shocks including commodity pricing
shocks not controllable by the domestic market.
1.2 Research questions
The
research questions postulated for this study include the following:
1. What
are the major causes of oil dependency on Nigeria’s economic growth?
2. Does a long run relationship exist
between
oil dependency and
economic growth in Nigeria?
3. What
are the factors that could minimize Nigeria’s over dependency on oil revenue?
1.3 Objectives
of the study
The
broad objective of this study is to examine the relationship between oil dependency
and the Nigerian economy. However, the
study will pay particular attention to the following specific objectives:
1. To
assess the causal relationship between oil revenue and Nigeria’s economic
growth.
2. To determine long relationship between oil dependency and
economic growth in Nigeria.
- To analyze the implication of over dependency on oil
revenue in the country.
1.4 Research hypotheses
For
the purpose of this study, the following research hypotheses will be
tested.
1. Ho: There is no significant causal relationship
between oil revenue and economic growth, in Nigeria
Ho: There is significant causal relationship
between oil revenue and economic growth, in Nigeria
2. Ho: There is no significant long run
relationship between oil dependency and economic growth in Nigeria
H1: There is significant long run
relationship between oil dependency and economic growth in Nigeria
3. Ho: Overdependence on
oil revenue has more negative effect than positive effect on Nigeria’s economic
growth.
H1: Overdependence on
oil revenue has more positive effect than negative effect on Nigeria’s economic
growth.
1.5 Significance of the study
The
study is significant because it assesses the impact of Nigeria’s overdependence
on oil revenue. Also, the study will help direct attention of the federal
government and the oil sector on the need for diversification into other
sources of revenue like agriculture, for economic growth. It will also serve as a reference for future
researchers in the same field.
1.6 Scope of the study
The
study is on assessing the impact of overdependence on oil revenue to Nigeria
economy. The study focuses on the impact of overdependence on oil revenue to
Nigeria economy, factors that could minimize Nigeria’s overdependence on oil
revenue, the level of importation of petroleum products in Nigeria and problems
encountered by the Nigerian oil sector. However, the study will be carried out
in the Federal Ministry of Finance, Abuja.
1.7 Limitation of the study
The
main constraints of the study include the following:
Time: Due
to the limited time given for the study, the researcher could not get all the
required information needed for the study.
Finance: The
researcher has not got enough money to embark on the study and therefore could
not visit places where information relevant to the study could be
obtained.
Attitude
of the Respondents: The attitude of the respondents
affected the research work because some of the respondents were unwilling to
co-operate with the researcher. They felt they have nothing to benefit from the
study.
1.8 Organization of the research work
The
paper is organized as follows:
- Chapter two reviews the literature from
mainstream and structural economists on topics of natural resource dependency,
economic growth and industrialization which is directly related to the topic of
the paper. The result of the literature review is synthesized into a brief
summary.
- Chapter three gives an overview of the Nigerian
economy and an overview of the natural resource and industrialization based
policies which were meant to promoted economic growth and development.
-
Chapter four analyzes the macroeconomic data available for Nigeria regarding
GDP, oil prices and manufacturing.
-
Chapter five presents the conclusion and recommendations.
