ABSTRACT
This
study examined the impact of export earnings in the economic growth of Nigeria.
The data for this research work was obtained from the CBN Statistical Bulletin
(1981 – 2013) and analyzed using ordinary least square (OLS) technique. Gross
domestic product (GDP) was regressed against Nigeria oil export (NOXP),
Nigeria non-oil export (NNXP), and Domestic investment (INV). Co-integration test revealed that the entire
variables have long run relationship with economic growth in Nigeria within the
sampled period. The unit root test indicated that the entire variables were
stationary at first differencing The result of the
coefficient of multiple determination showed that 79.53% of the variation in
the gross domestic product (GDP) are explained by the variation of the
explanatory variables namely; Nigeria oil export (NOXP), Nigeria non-oil export
(NNXP), Domestic investment (INV), while the remaining 20.47% is explained by
variable not included in the model. Based on the findings, the researcher
recommends among others that; Federal Government of Nigeria should
revamp both local industries and agriculture through subsidies, concessions,
uninterrupted power supply, technical assistance, improving security of lives
and properties and the creation of enabling business operating environment.

The study of economic growth cannot be properly Discussed without
mentioning trade as an engine of economic growth, be it domestic trade or trade
with other countries. The new classical
economists, for example, drawing from historical evidence from the nineteenth
Century, likened trade to an “engine of growth” (Nurske, 1961). Also, Kravis
(1970) dubbed trade to be the “handmaiden of growth”. It has, therefore, become
imperative for every Government to pay keen attention to matters relating to
trade especially how to attain a higher real productivity in the export sector.
Exports are goods and services produced
domestically and purchased by foreigners. Net exports are the difference between total
exports and total imports. According to Afolabi (2011) Export can be defined as
surplus goods and services of a country that are sent to other countries in the
world for sale.
Samuelson and Nordhaus (2010) see exports
as the mirror image of imports. That one countries export is another’s imports.
However, export is any goods or commodity transported from one country to
another country in a legitimate fashion typically for use in trade (Oluchi, 2007).
Just as there have been a continue
increase in the importance of foreign trade so, also have the study of the
concept by researchers been on an increase. This however, has led to the
evolvement of several theories to analyze the impact of export on economic
growth. According to Bbaale and Mutenyo (2011) as cited in Ugwuegbe and Uruakpa
2013) the present literature presents several plausible theoretical arguments
supporting the view that exporting activities and overall economic growth are
positively associated. On the one hand, exporting implies that a country gains
access to the wider external demand, which acts as a stimulus to domestic
output and hence economic growth. Second, it is frequently argued that small
domestic markets may not grow continuously and that any positive economic shock
leading to the expansion of the domestic markets is more likely to decay
quickly. On the other hand, large external markets do not always encompass
growth restrictions of economies of scale. However, the relationship between
exporting and economic growth remains controversial as some authors have argued
that export growth precedes economic growth hence giving a stance to the
export-led growth (ELG) hypothesis (Arnade et al, 1995; Fosuthornton, 1996).on
the other hand, others have provided evidence in support of the growth-led
export hypothesis (GLE) by arguing that economic growth comes before export
growth (Krugman,1984,Lancester,1980;Henriques and Sadorsky, 1996; Al-Yousif,
1999;Kernel et al, 2002).
Nigeria, like many other developing
countries in Africa, started as a purely Agrarian economy. Nigeria major agricultural
produce include beans, cassava, cocoa beans, groundnuts, palm oil, rice,
rubber, timber, yams, amongst others. These products accounted for over 50
percent of Gross domestic product (GDP) and were the main source of export
earning and public revenue. With cocoa being the leading export earner and
seconded by rubber. Agricultural exports (including manufactured food and
agricultural products) decreased quantitatively after 1970 this can be
attributed to low world price of primary products.
The Government of Nigeria, in 1979,
banned the importation and exportation of many foods (Encyclopedia of the
Nation 2007). Again, following the discovery of oil and the buoyant oil revenue
in the 1970’s relegated agriculture to the background; this is a result of
crude oil constituting about 90 percent of total export. However, in the 1980
the world oil market collapsed. The collapse resulted in drought in oil earning
and budgetary receipts without a proportionate slow down in fiscal and external
deficits. In a bid to finance the domestic and external deficits, government
resorted to heavy borrowing from the banking system, international financial
institutions and depleting of external reserves. The subsequent decline in
foreign exchange earnings also triggered an unperfected economic crisis (Omotor
and jike, 2006).it is in response to these immense problems that the structural
Adjustment program (SAP) was introduced in the late 1980s. This was aimed at
liberalizing and diversifying the economy.
SAP was designed to pay more attention to export, especially in the
Agricultural sector, which witnessed the worst neglect. The adoption of SAP was
followed by formulation of several export promotion strategies and policies
especially on manufacturing export. Which include various incentives on export,
Researched and Development (R&G), privatization of state owned enterprises
and host of others.
In the light of
the above, this research work aims at analyzing the effect of export earning fluctuations
on Nigeria’s economic growth.
Nigeria is generously endowed with abundant natural resources such as
crude oil, columbite, limestone, Cole, lead, iron-ore, tin, with a whole lot of
Agriculture produce amongst which are cocoa, rubber and timber. All these
resources if carefully and properly harnessed would foster the economic growth
and development of Nigeria. Yet the Nigeria economy has from time to time been
crippled by issues like corruption, balance of payment problem, High Debt,
Inflation, and Unemployment. Despite all the numerous blessings Nigeria still
remain underdeveloped whereas she stands a better chance, as the giant of
Africa, to become one of the world leading economies.
In the decades of the 1960’s and 1970’s
the Nigeria economy was dominated
by Agricultural commodity export such as cocoa, groundnut, cotton, rubber,
coffee, beniseed and palm produce which are basic raw materials for a wide
range of manufactured goods. By 1950’s and 1960’s, 3%-4% annual output growth
rates for agricultural food crops were achieved. Government earning also
depended heavily on taxes on export. Thus, during the period, the current
account and fiscal balances depended on the agricultural sector. Until the
early 1970’s where reliance was shifted to crude oil (Osuntogun et al, 1997).
Gani (2011) noted that with the oil boom in mid 1970’s was an immense rise in
the country’s foreign exchange earning which in turn resulted in a higher
economic growth. The period is also characterized by high level of expenditure
in the part of Government on capital intensive project and administration cost.
In the late
1970’s and early 1980’s, there was a fall in world oil price and this resulted
to series of macroeconomic problems as a result of the over dependency on oil
sector. Amongst the macroeconomic problems that emerged are high rate of
unemployment, price instability, balance of payment deficit, budget deficits
which led to Government borrowing from external bodies so as to meet up with
capital intensive projects.
However, in response to these enormous problems the government has
embarked on several policy reforms as a way of liberalizing and diversifying
the economy. Prominent among the policies is the Structural Adjustment
Programme (SAP). Some previous studies show the relationship between exports
and Nigeria economic growth while other showed the extent at which oil export
and non-oil export individually affect the economic growth of Nigeria. This study,
however, failed to analyze clearly the effect of Bank credit on export earning
cum economic growth of Nigeria. This research work will attempt at verifying
the effect of this variable and hence closed the gap in knowledge inherent in
other studies.
1. To
what extent do export earnings impact on the economic growth of Nigeria?
2. What
is the long-run relationship between export earning and economic growth of
Nigeria?
3. What
is the direction of relationship between export earning and economic growth of
Nigeria?
The objectives of this study are
to:
1. Examine the
impact of export earning on the economic growth of Nigeria.
2. Investigate
the relationship between export earning and economic growth in Nigeria.
3. Investigate
the long run relationship between export earning and economic growth of
Nigeria.
Ho:
Export earning has no significant impact on the economic growth of Nigeria.
Ho:
Export earning has no significant relationship with economic growth in Nigeria.
Ho: Export earning has no long run relationship
with economic growth in Nigeria.
The impact of export earning fluctuations on the sustainable growth of
any nation cannot be over-emphasized; since increase in export earnings (over
its counterpart, import) would make any Nation better-off in trade with other
countries. Therefore, this work will be of immense importance to government and
its agencies, and the general public.
Also, it will be of great importance to ministry of trade and industry,
investors as well as financial intermediaries or institutions. Above all, it
will be a stream of knowledge for economist, students and researchers who have
interest on issues relating to export.
This research will analyze the
effect of export earning fluctuations in Nigeria economy, taking proper
analysis on various ways and means put by the government of Nigeria to improve
export earning since 1981-2012.
The research work, however, is not void of constraints as the researcher
encountered a number of constraints in the cause of this work. The constraints
include data sourcing as well as data inconsistency due to poor nature of
information management in Nigeria. However, host of other constraints that
prevent the researcher to present a better work than this abound. Prominent
among them are time factor, financial constraints and lack of electricity.
