ABSTRACT
The study evaluates government labour/employment policy, graduate unemployment and
labour productivity in Nigeria. It spanned the period between 1987 and 2013. The
model was built on the combination of Keynesian framework and modern labour market
theory and the various channels through which labour policy can impact on graduate
unemployment and labour productivity in Nigeria. The study employed Ordinary least
square method of estimation, co-integration and error correction techniques in
estimating the model. Data were sourced from Central Bank of Nigeria annual statistical
bulletin/reports (various years) and National Bureau of statistics annual statistical
reports. The econometric software used for the study was E-views. The result from trend
analysis showed that labour productivity proxied by growth in Gross Domestic Product
(GDP) maintained steady and near horizontal movement while graduate unemployment
has been on the increase over the years. Co-integration result showed that there exists a
long-run linear relationship among the variables used for the study, hence adopting an
error correction model. The result clearly indicated that government employment policy
proxied in this study by the total number of graduates that have benefited (TNA) from
National Directorate of Employment (NDE) since its inception in 1986 have positive and
significant influence on labour productivity and negative significant influence on
graduate unemployment. The study also found insignificant relationships between
graduate unemployment, gross secondary school enrolment and total factor productivity
in Nigeria. The study went further to establish unidirectional causal link between
government labour policy, graduate unemployment and labour productivity in Nigeria.
The study recommends that holistic programme should be established to arrest high
trending unemployment in Nigeria. The programme should capture those who are
heavily underutilized and grossly underpaid, in order to have a fair representation of the
unemployment situation in the country. Government spending pattern should be checked,
since the rising government total spending has not translated to increase in labour
productivity.

CHAPTER ONE
INTRODUCTION
1.1 Background of the Study
There is no doubt that unemployment is one of the major challenges facing economies of
the world (developed and developing). This exerts more distorting impacts on the developing
economy. According to Ekpo (2008), a developing economy such as Nigeria’s is faced with
poor growth performance which manifests in the rising incidence of poverty, massive graduate
unemployment, skyrocketing inflation, worsening balance of payments disequilibrium,
monumental external debt burden, widening income disparity and growing fiscal imbalances,
which taken together can be said to constitute major causes of underdevelopment. In all, rising
graduate unemployment poses the most pervasive and devastative effect which threatens the
productivity of the Nigerian economy (Ake, 2010).
Graduate unemployment is defined as the unemployment among people with academic
degrees. It is a situation where tertiary institution graduates do not get jobs after going through
the academic ladder successfully. It is the greatest component of aggregate unemployment.
According to the International Labour Organization (1982), the unemployed are persons that are
available and willing to work but without work in the past 39 weeks. One is forced to ask how
many Nigerians are willing and available to work but are currently without job. On the other
hand, Frank and Bernard (2001) noted that the rising unemployment rate in a nation is too
significant to be ignored as it is necessary in assessing the level of economic activity in such
nations. Thus, besides real GDP, unemployment and growth in labour productivity remains
economic statistics that receives a great deal of attention from both economists and the general
public.
The unemployment rate is a sensitive indicator of the conditions of the labour market. When
the unemployment rate is low, jobs are secured and relatively easier to find. Low unemployment
is often associated with improving wages and working conditions as well as employers
competing to attract and retain workers.
In the recent past, Nigeria has experienced low labour demand and productivity, a sign
which is widely blamed on the failure of government policies and programmes over the years.
Specifically, since the mid 1980s, there has been an alarming increase in the rate of graduate
unemployment, low labour productivity and its attendant’s social and economic consequences.
Just like some other developing nations in Africa, the Nigerian government and policy makers
are increasingly finding it difficult to deal with graduate unemployment successfully.
2
The high rate of graduate unemployment in Nigeria according to Adeyeye et. al. (2012),
can be associated with lack of adequate provision for job creation in the development plans, the
ever expanding educational growth and the desperate desire on the part of youths to acquire
tertiary education irrespective of the social and economic reality. Consequently, a number of
skills acquired from these tertiary institutions appear dysfunctional and irrelevant since most of
the skills and knowledge acquired in tertiary institutions are kept redundant through
unemployment and sometimes skills are not fully utilized.
On the other hand, as the graduate population in Nigeria increases without being
absorbed in the active market, labour productivity does not increase at its full potentials, this
could be as a result of the failure of government to control this phenomenon over the years in
spite of numerous programmes and policies on this issue. Without denying the impact of other
factors, unemployment has exacerbated social ills and delinquent behavior among youths (most
of whom are graduates) especially armed robbery, political thuggery, advanced fee fraud and the
recent spate of terrorism (Boko Haram) in Nigeria, which has been on rampage for the past 4
years, forcing the government to be spending a lot of money on crime control. Recent statistics
released by the National Bureau of Statistics (NBS) showed that about 10 million Nigerians
were unemployed. In fact, this number swells by 120,000 graduates each year, which are
produced with little or no jobs waiting for them. (NBS 2009).
In a bid to address the menace of unemployment, various policies have been put in place
by the Federal Government of Nigeria. Notably, the Small and Medium Enterprise Development
Agency of Nigeria (SMEDAN) was established in 2003 to promote the development of Micro,
Small and Medium Enterprises (MSME) sector of the Nigerian economy. It is to source, process
and disseminate business information, develop policy, establish business support programmes,
build capacity and promote services, enhance MSME access to finance. Others are the Nigerian
Agricultural Co-operative and Rural Development Bank (NACRDB) Limited which is dedicated
to financing agriculture at both micro and macro levels. They are to provide affordable financial
and advisory services to the farm and non-farm enterprises of the Nigerian economy using well
trained and highly motivated staff, backed by appropriate technology. Those that were
established but later scrapped include: the Directorate for food Roads and Rural Infrastructures
otherwise known as (DFRRI), Mass Mobilization for Self Reliance and Economic
Reconstruction (MAMSER) and the National Agricultural Land Development Project
(NALDA). These were created by the Babangida regime but scrapped by the Abacha regime.
Among all, the most innovative of these programmes is the National Open
Apprenticeship Scheme (NOAS) introduced by the Federal Government in 1987. The NOAS is
3
an attempt to link education with training and labour demand. It was managed by the National
Directorate of Employment (NDE) under the Ministry of Labour and Productivity. The NDE is a
policy document that addresses the provision of graduate level of employment, the essence of
this is to know how government policy should be used effectively in the reduction of graduate
unemployment and enhance productivity in Nigeria. This was also meant to provide vocational
education and training to unemployed youth in over 100 occupations. The main objective of
these government programmes and policies is to provide means of livelihood to able but idle
army of unemployed youths, especially the graduates and give assurance to the private sector
through the services of the youths.
Unfortunately, the observable low labour productivity and high level of graduate
unemployment over the years in the country have shown that no meaningful progress has been
made by these programmes and policies. It is against this background that this study is designed
to examine the nexus between government policy, graduate unemployment and labour
productivity in Nigeria and its attendant consequences to the social and economic wellbeing of
the nation.
1.2 Statement of the Problem
Tackling graduate unemployment and low labour productivity in Nigeria has remained
twin problems facing the country for some decades now. The Nigerian total labour force is made
up of all persons aged 15-64 years excluding students, home keepers, retired persons and stay-at-
home to work or those that are not interested. Nigeria’s unemployment can best be defined as the
proportion of labour force that was available for work but did not work in the week preceding the
survey period for at least 39hours (Asoluka & Okezie, 2009). The 2009 official figures from the
Bureau of Statistics put the unemployed figure at 19.70 per cent, about 30 million. Though, this
figure still did not include more than 40 million other Nigerian youths (some graduates of various
degrees) captured in World Bank statistics in 2009. By implication, it means that if Nigeria’s
population is 167 million, according to World Bank figure, then 50 percent of Nigerians are without
employment (unemployed). Viewing this from the perspective of the recent events in the Middle
East where unemployment and poverty among others played a key role in the uprising, one can only
conclude that Nigeria’s unemployment poses a threat to not only productivity and output growth, but
its security and peaceful co-existence.
The rising trend of unemployment assumed a doomsday scenario in Nigeria a decade
after political independence. As noted by Akintoye (2008), between 1970 and 1980, national
unemployment rate rose from 4.3 to 6.4% and further rose to 7.1% in 1987. This, according to
Akintoye, is attributed to the economic depression which engulfed the nation from 1980,
4
resulting in massive closure of businesses and retrenchment of workers. This was followed by
the placement of embargo on recruitment which further worsened the unemployment situation.
The Structural Adjustment Programme (SAP) established in 1986 had on its part, a
positive effect on job creation leading to a sharp fall in unemployment rate from 7.1% in 1987 to
1.8% in 1995. Thereafter, unemployment figure hovered around 4% between 1996 and 2000.
One worrisome trend in the Nigeria labour market of recent has been the growing incidence of
unemployment among professionals such as accountants, engineers and other graduates from
universities and other tertiary institutions. Graduate unemployment accounted for 32% of the
total unemployed labour force between 1992 and 1997 (Akintoye,2008). This growing incidence
of graduate unemployment in the face of acute skill shortages presents a paradox which further
complicates the analysis of labour market distortions in Nigeria. (Dabalen et al., 2000).
Expectedly, unemployment reduction has remained the central focus of macroeconomic
goals in Nigeria. It is a continuing policy and responsibility of the federal government to use all
practical means to promote higher level of employment, production and purchasing power
(Essien & Atan, 2006). The most critical factor explaining the rising unemployment in the
country is the failure of government policies to consciously tackle graduate unemployment
among others. The need to avert the negative effects of unemployment and improve labour
productivity through effective government policies will make the tackling of unemployment
problems to feature prominently in the development objectives of the Nigerian government.
The primary cause of graduate unemployment and low productivity is the absence of an
appropriate and well articulated government policy to guide the strategies and programmes of
the various institutions operating in all sectors of the economy (Asoluka & Okezie, 2011).
However, efforts by different regimes in Nigeria such as Federal Ministry of Labour and
Productivity, the National Directorate of Employment (NDE), Small and Medium Scale
Enterprise (SMEs) and National Poverty Eradication Programme (NAPEP) in 2001 to generate
more employment and improve labour productivity to a large extent have not yielded the
required results (Essien & Atan, 2006).
Apart from representing a colossal waste of a country’s manpower resources, graduate
unemployment and low productivity generates welfare loss in terms of lower output thereby
leading to lower income and wellbeing (Ibrahim, 2006). In 2005 the unemployment rate as
recorded by the NDE was 11.9% in 2006, 14.6% in 2007, and 10.9% in 2008 while as at
December 2009 the Bureau of Statistics gave the unemployment rate as 19.7%. Predictably, this
has also been accompanied by a high rate of social vices in Nigeria.

In view of the unfolding reality coupled with the protracted debates in the literature, this
study is built to examine the nexus between government policy, graduate unemployment and
labour productivity in Nigeria. In doing this, the study will be guided by the following research
questions.
1.3 Research Questions
1. What is the nexus between government labour policy, graduate unemployment and
labour productivity in Nigeria?
2. What is the long-run impact of graduate unemployment on total factor productivity in
Nigeria?
3. What are the causality between government policy, graduate unemployment and labour
productivity in Nigeria?
Based on the above research questions the following objectives are drawn for this study.
1.4 Objective of the Study
The broad objective of this study is to examine government labour policy, graduate
unemployment and labour productivity in Nigeria. In view of this, the specific objectives of the
study are;
1. To determine the nexus between of government labour policy, graduate unemployment
and labour productivity in Nigeria.
2. To determine the long-run impact of graduate unemployment on total factor productivity
in Nigeria.
3. To determine the causality between government labour policy, graduate unemployment
and labour productivity in Nigeria.
1.5 Research Hypotheses
Based on the objectives of this study, the following research hypotheses are formulated:
1. Ho: Government policy on labour has no significant impact on the rate of graduate
unemployment and labour productivity in Nigeria.
2. Ho: There is no long-run relationship between graduate unemployment and total factor
productivity in Nigeria.
3. Ho: There is no causal link between government labour policy, graduate unemployment
and labour productivity in Nigeria.

1.6 Policy Relevance of the Study
The findings of this study will aid the government efforts in addressing the protracted
unemployment, especially graduate unemployment and low labour productivity in Nigeria.
Firstly, identification of the nexus between government labour policy, graduate unemployment
and labour productivity in Nigeria will assist policy-makers in formulating the right policies to
addressing protracted rising unemployment trend in Nigeria. Policy-makers will therefore find
the study very relevant for drawing policy issues in line with the challenges of ensuring an
improved labour productivity and reducing general unemployment rate, irrespective of gender
and level of education, in line with the development agenda of the present administration.
Secondly, investigating the long-run impact of graduate unemployment on total factor
productivity will be informative in predicting how total factor productivity will change if policy
makers are to change in reducing the rising trend of graduate unemployment status. Finally,
providing an insight towards understanding the causal relationship between graduate
unemployment, government labour policy and low productivity in the Nigerian economy, will
be an important tool in designing effective policy interventions that addresses graduate
unemployment and labour productivity issues and achieving the new policy framework (mass
employment for the youths).
1.7 Scope of the Study
This study is an empirical analysis of the nexus between government labour policy,
graduate unemployment and labour productivity with evidence from the Nigerian economy. It is
important to note in this study that the connection between government policy and
macroeconomic phenomenon such as unemployment is not well developed. In principle, a
computable general equilibrium model (CGE) should be developed; however, unemployment
sensitive CGE models have not been developed and face many problems (Fontana & Wood,
Lofgren et al., 2008). Hence these are beyond the scope of this study. Instead, this study
addresses three graduate unemployment issues that are thought to affect both the demand as
well as supply of labour in Nigeria. These are the interaction between employment rate, labour
demand and the number of graduates produced in the economy every year.
This study considered the effective government labour/employment policies instruments
targeted at graduate unemployment in National Directorate of Employment (NDE) scheme.
These include the start your Own Business (SYOB) under the small Scale Enterprise programme
(SSE), the sensitization of National Youth Service Corps (NYSC) on Entrepreneurship
development, the Graduate Attachment Programme (GAP) and the Solar Energy Training
7
Scheme (SETS) which was recently introduced. However, the study estimated the government
labour policy with the total number of persons that benefited from NDE graduate programmes
annually (TNA).
Total Factor Productivity (TFP) is a notion linked to the aggregate production function.
Hence total factor productivity was measured in this study as the ratio of output and weighted
input factors (to be specified in the methodology). Productivity, on the other hand, is a technical
concept which refers to a ratio of output to input and a measure of efficiency. (see Classical
Ricardian labour theory of value).
Finally, graduate unemployment is referred to as graduates who were available for work
and looking for jobs, but unable to find employment. Again, this study covers a reasonable range
of observations, ranging from 1987 to 2013 in order to have a clear picture of the nexus between
government labour policy, the rate of graduate unemployment and labour productivity growth in
Nigeria. This period was chosen due to the fact that government labour/employment policy
considered in this study is captured from the National Directorate of Employment which was
established on November 22, 1986 and its initial core programmes were formally launched on
30th January 1987.

CHAPTER TWO
LITERATURE REVIEW
2.1 Theoretical Literature
Theories of Unemployment
Scholars have propounded various theories relating to employment, underemployment
and unemployment. These include those of the Classical theory of unemployment, Innovations
theory of unemployment and Effective Demand theory of unemployment.
Classical Theory of Unemployment
The classical theory, as analyzed by Pigou (1933) and Solow (1981), argues that the
labour market consists of demand and supply of labour. Demand for labour is a derived demand,
obtained from the declining portion of the marginal product of labour. The demand curve is a
negative function of real wage in that if wages increase, the quantity demand for labour will
decline and the opposite is correct. The supply of labour is derived from worker's choice
whether to spend part of their time working or not working (leisure). Supply of hours worked is
a positive function of the real wage, because if the real wage rises, workers supply more hours of
work. In equilibrium, demand and supply of labour are intersected at a clearing point that
determines the equilibrium real wage rate and full employment.
Essentially, for Wicksell the cyclical unemployment was due to the wrong investment of
capital. Capital was invested in areas where rates of return were low. He concluded that public
works is the best measure to fight cyclical unemployment. After World War I, Wicksell thinks
that the boom and the rise in prices induced by the war would come to an end. Thus,
unemployment would rise. Workers would have to accept lower wages. He also thought that
government should provide financial support to the unemployed who could not find jobs. After
1921, Wicksell turns to Malthus. He thought that the causes of the unemployment are the surplus
people, shortage of capital brought about by the war, and the disorganized state of the monetary
system. For the third cause, after the war prices were falling and producers decided to produce
lower amounts of production because they knew they would receive lower prices for their
products. Thus, they let their money lie idle in banks and workers became unemployed. These
causes suggest that emigration became one of the important policies for solving the
unemployment problem.
Wage reduction is not a competent policy to increase employment. The increase in
wages is most likely due to increased labour productivity and wage reduction will reduce work
9
intensity and productivity. Wage reduction will not force some capital intensive firms to switch
to labour intensive techniques in the short run. Higher wages should stimulate the substitution
effect by employing more machines for labour. And this substitution will increase labour
productivity and employment in the long-run.
Hayek contends that unemployment is due “to a discrepancy between the distribution of
labour and industries, and the distribution of demand among their producers. This discrepancy is
caused by a distortion of the system of relative prices and wages.” In other words, the
unemployment is caused by “a deviation from the equilibrium prices and wages which would
establish them with a free market and stable money.” This is actually a mismatch between
demand and supply of labour, which is usually caused by expansionary monetary and fiscal
policies and powerful trade unions. These policies create economic dislocation and structural
changes in an economy which misdirect labour and other economic resources to other
alternatives. Unions are also able to set higher wages compared to market wages, which generate
unemployment, particularly in industries that become less profitable. In short, for Hayek the
unemployment problem is caused by resources being in the wrong places at the wrong time and
can be corrected if wages and prices are determined by the equilibrium of supply and demand.
(Nishhiyama and Leube 1984)
In line with Hayek theory of unemployment, Trehan (2001) provides an important
explanation of the search theory of unemployment. Firms search for the productive workers and
workers search for high-paying jobs, so both agents continue searching until matches are
reached at the point a worker will leave the unemployment pool. But if a worker realizes later on
that her productivity is worth higher wages and firms are paying high wages on the average, then
the worker’s reservation wage will increase. Consequently, the unemployment rate will start
rising gradually, indicating that a mismatch has occurred again.
Innovations Theory of Unemployment
Originally, this theory was developed by the German economist Von Mangoldt in 1855
in a book of entrepreneurial profits which connected profits to risk but this theory was refined in
2007 by Ekelund and Hebert. They provided several ways by which the entrepreneur can make
profits. These ways are (1) finding particular markets, (2) acquisition of productive agents, (3)
skillful combination of factors of production, (4) successful sales policy, and (5) innovations. It
is a well understood proposition that entrepreneurial profits will increase employment
(Mohammed 2010).
Schumpeter (1934) does not provide explicitly a theory of unemployment but his theory
of the business cycle does demonstrate clearly how unemployment can be reduced. Innovation
10
(see also Vecchi 1995) which creates more jobs relative to job destruction is the basic force
beyond the increases in employment and the decreases in unemployment. When entrepreneurs
innovate something new such as the production of a new product, the finding of a new market,
the finding of a new method of production, and the introduction of new technologies and a new
organization they increase investments to materialize those innovations. Domestic investment
expenditures will increase demand on economic resources and will increase their prices. Other
entrepreneurs will imitate the leaders by adopting the new innovations. Labor and materials will
be employed to produce the new items. Consequently, wages will be increasing and
unemployment will be declining, assuming that employment creation will outweigh employment
destruction due to the new innovations (see also Mortensen and Pissarides 1998 and Manuelli
2000).
According to Schumpeter (1934: 64), economic development generates changes in the
socio-economic environment, including the existing equilibrium. As he puts it, “Development is
spontaneous and discontinuous change in the channels of the flow, disturbance of equilibrium,
which forever alters and displaces the equilibrium state previously existing.” The essential
driving force for generating development is innovations introduced by the entrepreneurs whose
leadership becomes the triggering device for the discontinuous dynamic changes. Innovations
start by “the producer [not consumer] who as a rule initiates economic change and consumers
are educated by him if necessary” (Schumpeter 1934: 65).
The concept of innovation which creates changes according to Schumpeter (1934: 66)
covers the following five areas of development: “(1) the introduction of new good...or of a new
quality of a good. (2) The introduction of a new method of production, (3) The opening of a new
market,(4) The conquest of a new source of supply of raw materials, or manufactured goods,(5)
The carrying out of the new organization of any industry, like the creation of a monopoly
position or the breaking up of a monopoly position.” The new combinations are usually
embodied in new productive enterprises which start by utilizing the unemployed working
people, the unsold raw materials, the new technologies, and the unused productive capacity.
Effective Demand Theory of Unemployment
The level of aggregate demand will provide the necessary increases in total revenues. On
the other side, the cost of production has to decline. If revenue rises and cost declines, then the
reasonable level of profits can be found. There are various forces in Veblen’s work that reduce
the cost of production. Technology increases production and reduce the cost of inputs used in
the production process, and enterprises cut wages and increase productivity in order to cut cost
per unit of output. Better technology can reduce the prices of capital goods, and government can
11
cut taxes. Banks can reduce the interest rates as well. Administrative and insurance cost can be
declined in order to stimulate business enterprises. The decline in costs, given rising revenues,
will increase the profit level according to Veblen. Consequently, higher profits will force the
business enterprises to expand and employ more workers. Thus, employment will increase and
the rate of unemployment will decline.
Keynes (1936) considers unemployment as an involuntary phenomenon. He thinks that
employment is cyclical, generated by the deficiency of aggregate demand (Mohammed, 2010).
Capitalists hire workers and invest to produce output when the expectations about the economy
and profits are favorable. If expectations about the future are supported by reality, investments
and employment continue rising until equilibrium is reached. This equilibrium is attained by the
intersection of the aggregate demand and supply--the point of the effective demand—which may
be less than the full employment equilibrium. If expectations about the future of the economy
are not favorable, capitalists invest less and employ less number of workers. Hence, the
equilibrium is achieved where cyclical unemployment exists. This unemployment is due to the
deficiency of the aggregate demand, particularly investment expenditures.
Graduate Unemployment and Government Policies
According to Olufemi and Adebola (2011), both government and policy makers are
increasingly finding it difficult to deal successfully with graduate unemployment, part of the
reasons was blamed on lack of adequate provision for job creation in the development plans of
the governments, thereby rendering the skills acquired dysfunctional and irrelevant to them and
the entire economy. But still more and more graduates are being turned out from the various
universities every year.
The Government of Nigeria had attempted to curb graduate unemployment. Firstly,
through the National Directorate of Employment (NDE), this is one of the steps taken by the
Nigerian government to reduce the problem of unemployment in Nigeria which was established
in November 22, 1986. The objective of NDE was to promptly and effectively fight
unemployment by designing and implementing innovative programmes, which are directed
towards the provision of training opportunities through the guidance and management support
services to graduate farmers and small scale entrepreneurs. The objectives of NDE spanned
across the following programmes: (i) Youth employment and vocational skills development
programme, (ii) Special public works, (iii) Small scale industries and graduate employment
programme, and (iv) Agricultural development programme.

The aim of the agricultural programme is to generate employment for graduates, non-
graduates and school leavers in the agricultural sector, with emphasis on self employment in
agricultural production and marketing. The programme is monitored by a team of agricultural
professionals in the agricultural department of the directorate. Chinedum (2009) shares the same
views as in Akintoye (2008), inadequate funding and late release of funds from the federation
account among others have impaired the effectiveness of the NDE agricultural programmes.
Also the National Economic Empowerment and Development Strategy (NEEDS) was
introduced in March 2004, in order to confront the various macroeconomic imbalances, social
challenges and structural problems in the Nigerian Economy.
To achieve this goal, the major target of NEEDS is to engineer wealth creation,
employment generation and poverty reduction. Sequel to this, Adebayo and Ogunrinola (2006)
pointed out that for NEEDS to achieve its objectives there is need to design many integrated
programmes that can generate employment for women and youths to enhance growth and
development. In combating unemployment problem, this further point out the need to seek help
in the informal sector in order to drastically reduces unemployment. Hence, unemployment and
government policy, according to Walterskirchen (1999) has positive relationship with economic
growth. GDP and unemployment are both rising in the long run. Employment will only increase
when GDP is increasing faster than productivity, On the other hand, the greater the amount of
goods and services produced, the greater the labour required for production; because economic
growth and employment go hand in hand.
Labour Demand and Graduate Unemployment
The gap that exists between the demand for and supply of university graduates in the
Nigerian labour market is a serious issue in Nigeria, and this has manifested in the prevailing
high level of graduate unemployment. This has serious adverse social and economic
consequences on the Nigerian economy, some of which are declining quality of education,
