CHAPTER ONE
INTRODUCTION
1.1 Background of the study
Nigeria gained an extra US$390 billion
in oil-related fiscal revenue over the period 1971 - 2005 (Budina and
Wijnbergen, 2008). What has the nation got to show for this? Despite
such windfall, Nigeria has an increasing proportion of impoverished
population and experienced continued stagnation of the economy
(Okonjo-Iweala and Osafo-Kwaako, 2007). The country, like many other
oil-rich countries (ORCs) economically underperforms many resource poor
countries (Karl, 2004). Her oil wealth has not been tapped to launch her
onto economic heights; rather, she suffers from what Robinson, Torvik
and Verdier (2006) describe as a resource curse a paradox of poverty
amidst plenty resources. Why? One popularly identified bane of the
country’s economic situation is the Dutch Disease Syndrome (DDS) the
structural economic imbalance resulting from poor management of oil
revenue, and perhaps its shocks. Windfalls that result from volatile oil
price surges/shocks overwhelmingly flow through the economy; expand the
oil sector and penalize the non-oil sector (Mieiro and Ramos, 2010).
The resulting decline in the non-oil sector reinforces sharp decline in
the economic growth rate when the price of crude oil falls. Budina, Pang
and Wijnbergen (2007), however, point out that DDS alone does not
explain the slow growth of the Nigerian economy, especially her non-oil
sector; rather, they identify volatility (or shocks) of oil price and
its effect on other macroeconomic variables as the bane.
Prior to the discovery of crude oil in
commercial quantity in 1956 (Adedipe, 2004; Odularu, 2007), the Nigerian
economy, though largelyagrarian (Canagarajah and Thomas, 2001), was
stable and steadily growing. The pleasant situation continued into the
1960s when agriculture played a dominant role in her economy in terms of
contribution to GDP and foreign exchange earnings (Kwanashie, Ajilima
and Garba, 1998). The stability and gradual growth of the economy
reversed in the era of oil-dominant economy. The reversed situation was
synonymous with decline in the roles played by agriculture. The sector
shrank in GDP contribution from 66% in 1958/59 (Kwanashie, Ajilima and
Garba, 1998) to 16% in 2004 (United State Agency for International
Development, 2006). Its contribution to the nation’s export revenues and
foreign exchange earnings plummeted from 86% in 1955-59 (Aigbokan,
2001) to 1.8% in 1996 (Balogun, 2001). These worrisome declines have
been attributed to growing activities of oil and mining industy in the
country (Kwanashie, Ajilima and Garba, 1998). Balogun (2001) attributes
this problem to the poor management of public resources and
inappropriate incentives, which in turn may not be unconnected with
overwhelming inflow of oil revenues in the 1970s. Crude oil has
metaphorically been referred to as the ‘black gold’ (Bamisaye and
Obiyan, 2006). The resource has redefined the global economy in general
and the Nigerian economy in particular. The impact of crude oil on
Nigerian economy has been double-edged. It has benefited the country in
some ways, and has in many other ways turned out to be a curse (Ogwumike
and Ogunleye, 2008). Crude oil’s contribution to GDP rose from 1.6% in
1960 to 11% in 2001 (Adenikinju, 2006). This contribution consists of
proceed from oil export, local sale of crude oil for domestic refining
and local sale of natural gas. However, the contribution has been
limited due to substantial involvement of foreign investors in the oil
sector, and consequent repatriation of the sector’s profits and
dividends abroad (Odularu, 2007). Crude oil also contributes over 90% of
foreign exchange earnings in Nigeria (Adedipe, 2004; Adenikinju, 2006).
Ogwumike and Ogunleye (2008) concur that the sector dominates other
sectors in contributing to export revenues. For instance, it was
responsible for over 98% of total export from the country in 2005.
Moreover, the sector contributes to provision of employment in the
country (Odularu, 2007). The contribution has however not been
relatively significant because it has limited linkages with the rest of
the economy (Ibrahim, 2007). As a result, the sector employs only 1.3%
of the total modern sector employment in Nigeria (Odularu, 2007). The
beneficial impacts of oil on Nigerian economy notwithstanding, the
country has not significantly developed (Odularu, 2007). This is due to
setbacks caused by oil-related activities. As noted earlier, the
structure of theeconomy has been mal-altered with the advent of oil.
Other sectors have relatively declined in size and contribution to the
economy while the oil sector has grown in size. For instance, the United
States Agency for International Development (2006) notes the
association between sharp rise in oil production in Nigeria in 2003 and
decline in agriculture as a percentage of GDP from 29% in 2003 to 16% in
2004. In the same vein, contribution of the manufacturing sector as a
percent of GDP has been in decline, in contrast to growth in the oil
sector (Adedipe, 2004). Have Nigerian economic setbacks been solely and
directly caused by oil activities? Reporting Perrings and Asuategi
(2000), Ibrahim (2007) points out that there is weak empirical support
for negative impact of natural resources on economic growth and
development. Thus, it can be inferred that the poor performance the
Nigerian economy may not be entirely due to oil activities, but to
factors relating to policy management of oil resources in the country.
1.2 Statement of the problem
This study is prompted by fewness of
studies on the impact of energy shocks on economic growth of
oil-exporting countries like Nigeria, unlike studies on oil-importing
countries (Olomola and Adejumo, 2006). Besides, the study attempts to
query into the general conclusions of many recent studies that oil price
fluctuations/market disequilibria have no impact on the Nigerian
economy (see Ikla et al, 2012; Chuku, Effiong and Sam, 2010; Olomola and
Adejumo, 2006, for a survey). Moreover, the study disagrees with these
studies on explanation of the impact of oil price on economy via
monetary variables like monetary supply and interest rates, having noted
that their premise derive from Bernanke et al (1997), a study that
focuses on an oil importing country, USA, rather than oil exporting
countries like Nigeria. This study aims to extend the frontier of
knowledge by estimating the impact of the oil price shocks on the
Nigerian economic growth using aggregate demand framework that
theoretically connect analytical variables, rather than just explaining
output behaviour by oil price and host of arbitrarily suggested
variables as done by earlier studies.
1.2 Objectives of the study
1. To examine the impact of oil price shock on the economy of Nigeria.
2. To analyze oil price shock in Nigeria from 1970 to 2014.
1.4 Research questions
1. Does oil price shock have any significant impact on Nigerian economy?
1.5 Research hypotheses
Ho: Oil price shock has no significant impact on Nigerian economy.
Hi:Oil price shock has significant impact on Nigerian economy.
1.6 Significance of the study
The impact of oil price shock on world
economy has been larger (Hamilton, 2003). In the past three decades, the
price of oil has been volatile and given the role in the Nigerian
economy, the effects of oil price shock have been very significant and
dis-stabilizing. Nigeria has been the major oil producer in African
continent but the attacks on oil refineries and the kidnapping of
foreign engineers by the movement for emancipation of the Niger Delta in
the Niger Delta region was reported to be one of the causes of oil
price increase from 2006 to 2007. This notwithstanding, in general,
Nigeria’s production can be considered to be not enough to affect the
international oil price, thus this assumption is appropriate (CBN,
2008).
1.7 Scope/Limitations of the study
This study is concerned with oil price
shock in Nigeria.The analysis covers the period from 1970 to 2014,
within which occurred many oil market equilibrium-disturbing events.
Limitations of study
- 1. Financial constraint-
Insufficient fund tends to impede the efficiency of the researcher in
sourcing for the relevant materials, literature or information and in
the process of data collection (internet, questionnaire and interview).
- 2. Time constraint- The
researcher will simultaneously engage in this study with other academic
work. This consequently will cut down on the time devoted for the
research work.
1.8 Definition of terms
Oil Price:Refers to the spot price of a barrel of benchmark crude oil.
Fluctuation:An irregular rising and falling in number or amount, it refersto the deviations along the path from one point to another.
