This document summarizes a journal article about the impact of interest rates on the development of emerging markets, using Nigeria as an empirical case study. It acknowledges people who assisted with the research. The abstract indicates that interest rates are difficult to forecast and impact borrowing costs for businesses. While higher rates could encourage savings in the long-run, current high rates in Nigeria of 12% are negatively impacting growth. The literature review discusses how inflation can stimulate or deter human capital formation and how interest rates influence savings, investment, and financial intermediation. It recommends Nigeria adopt pragmatic policies to reduce lending rates to single digits to boost the economy.

An Analysis of the Relationship between Fiscal Deficits and Selected Macroeco...IOSR Journals
This study investigates the relationship that exists between the Government Deficit Spending and selected macroeconomic variables such as Gross Domestic Product (GDP), Exchange Rate, Inflation, Money Supply and Lending Interest Rate. The period covered is 1970 (when the civil war ended) and 2011. Ordinary Least Squares (OLS) technique was adopted to analyze the relationships. The study concludes that Government Deficit Spending (GDS) has positive significant relationship with GDP. Government Deficit Spending also has positive significant relationship with Exchange Rate, Inflation, and Money Supply. Government Deficit has negative significant relationship with Lending Interest Rate and most likely crowd-out the private sector by raising the cost of funds. Deficit spending has been known to have adverse effects on the economy and government is advised to curtail excessive deficit spending. It is recommended that further research is done to establish other variables that are affected by government deficit spending.
This study examined the effect interest rate on economic growth in Nigeria. Augmented Dickey – Fuller (ADF), Bound Test and Autoregressive Distributed Lag (ARDL) were employed to examine the effect of impact of interest rate on economic growth in Nigeria. The unit root test showed gross domestic product was 1(0) while interest rate, investment and gross capital formation were 1(1). The result of the Bound Test indicated long run relationship among the macroeconomic variables employed in the study. The result of the ARDL indicated that interest rate had negative effect on economic growth both in short run and long run. However, in the long run investment and gross capital formation were established to have positive effect on economic growth with gross capital formation being insignificant. It was concluded that interest rate has a macroeconomic tool is not effective in stimulating economic growth in Nigeria. It was recommended that the level of interest rate should be adequately controlled for the purpose of stimulating economic growth without inflationary pressure. Finally, robust macroeconomic policies aimed at ensuring economic stability should be formulated in order to increase capital formation and attract investment in order to promote economic growth.

Financial Development and Economic Growth Nexus in Nigeriaiosrjce
The study assessed the impact of financial development on economic growth in Nigeria using time
series data from 1970 to 2012. The Autoregressive Distributed Lag bounds testing approach to cointegration
was utilized for this study. The result from the ARDL model indicate that the variables for this study are
cointegrated while the error correction term appeared significant and confirms that short-run disequilibria are
corrected up to about 50 percent annually. The empirical results reveals that financial development exerts
positive and significant impact on economic growth in the long-run while trade liberalization variables exert
negative impact on economic growth in the long-run indicating non-competitive nature of non-oil domestic
products in the international market. In the short-run, domestic credit is insignificant which indicates a dearth
of investible funds in the economy. There is evidence that financial development policies influence economic
growth in the long-run and not in the short-run. This study among others recommends the urgent need to
implement policies that will strengthen the deposit mobilization and intermediation efforts in the banking system
in other to deepen the financial system. Nigerian trade performance should be improved through economic
diversification and further availability of funds to private sector at competitive interest rate in order to produce
internationally competitive products.
The presentation describes the relation between Financial development and growth in Emerging Market Economies. It is primarily based on abstract. However, one can contact me for further details.
The study is on the effect of Net capital inflow on inclusive growth in Nigeria. This study seeks to deepen the understanding on how capital inflow creates opportunity for inclusive growth in Nigeria through increase in GDP per capita. The objective of the study were to : determine the effect of Net capital inflow , Net foreign direct investment and trade openness on inclusive growth in Nigeria. The study employed the time series data in its analysis. The period of analysis spanned through 1980-2015 and the dataset required for the analysis were sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin and National bureau of statistics publications. The study conducted trend analysis, descriptive analysis. The data were also tested for stationarity using the Augmented Dickey Fuller (ADF) unit root test and Ordinary Least Square (OLS) analytical techniques, cointegration test and error correction mechanism. It was evident from the unit root test that the variables were fractionally integrated while the cointegration test reveals that long run relationship exists among the variables. The findings equally reveal that capital inflow exerts significant negative influence on GDP per capita. This could be attributed to the problem of managing external capital flows which has been sub-optimal in most developing economies including Nigeria. The implication of this finding is that the perceived benefits that are associated with capital inflows tend not to hold sway in Nigeria over the sampled period which may be attributed to institutional and governance failure. Owing to the findings, this study recommends for the adoption of investment friendly policies and ensure transparency and good governance, appropriate economic management practices capable of supporting reforms in the Nigerian financial system and guide international capital inflows to ensure that the associated economic turnarounds are people-centered.

Macroeconomic stability in the DRC: highlighting the role of exchange rate an...IJRTEMJOURNAL
This study is part of a macroeconomic approach and seeks to identify the role of the rate of
economic growth and the exchange rate in controlling the macroeconomic framework. The approaches adopted
in this paper are part of Keynesian thinking on macroeconomic stability using the macroeconomic stability
index proposed by Burnside and Dollars (2004) and A. Amine (2005). Our results argue that economic growth
is causing macroeconomic stability and that the exchange rate is negatively and significantly accounting for
macroeconomic stability in the Democratic Republic of Congo.
Monetary Policy and Trade Balance in NigeriaYogeshIJTSRD
Nigeria apex bank Central Bank of Nigeria CBN has continued to battle with the job of reviving the ailing economy and putting it on the path of growth. The economy has witnessed unprecedented job loss, rising poverty level, accelerating inflation, sluggish economic growth and disequilibrium in the balance of trade. The study therefore examine the effect of monetary policy on trade balance in Nigeria. Specifically the study ascertained the extent to which inflation, demand deposit, liquidity ratio, exchange rate and interest rate have influenced trade balance in Nigeria using an econometric regression model of the Ordinary Least Square OLS . From the result of the OLS, it is observed that monetary policy rate, demand deposit, liquidity ratio and exchange rate have a significant positive impact on foreign trade in Nigeria. This means that increases in monetary policy rate, demand deposit, liquidity ratio and exchange rate, will lead to increase in foreign trade in Nigeria. On the other, inflation rate and interest rate has a significant negative impact on foreign trade in Nigeria, meaning that as inflation rate and interest rate increases, will be bring about a decline in foreign trade in Nigeria. Based on the findings of this study, the study recommends that the government should employ a contractionary monetary policy to fight inflation by reducing the money supply in the country through decreased bond price. inflation, demand deposit, liquidity ratio, exchange rate and interest rate have influenced trade balance in Nigeria. The government should intervene in the foreign exchange market in order to build reserves for themselves or provide them to the bank to help stabilize the exchange rate. The government should strive to improve trade performance in the short and long run. They should also reduce government spending and tax capital inflow.

Foreign Aid and Fiscal Behaviour in Nigeria: An Impact Assessment of Deregula...iosrjce
The study examined the influence of deregulation on the relationship between foreign aid and fiscal
behaviour in Nigeria. The equation which described foreign aid as function of important fiscal variables and
other macroeconomic variables is derived from the famous two-gap model. Chow test is used to examine if there
is any structural changes since the adoption of deregulation that has significantly affected the relationship
between foreign aid and fiscal behaviour. The result shows that deregulation has positively and significantly
affected the impact of fiscal behaviour in Nigeria on foreign aid accessibility. But the effect has been short-lived
recently owing to the recent drastic fall in foreign aid available to Nigeria despite the sustained increase in both
government revenue and expenditure. It is recommended that assessment of other shocks that can affect the
fiscal behaviour in Nigeria should be conducted with a view to getting the reason why deregulation fails to
maintain positive relationship that exists between fiscal behaviour and foreign aid in Nigeria.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

Abstract
The study reveals that interest rate is always difficult to forecast. Interest rates will probably rise with the
removal of public sector funds from the industry. The interest rate (MPR) is the rate at which banks borrow from
Central Bank to cover their immediate cash shortfall. The higher the cost of such borrowing, the higher also will
be the rate banks will advance credit to the real sector. However, in the long-term, with re-capitalization on
banks, insurance companies’ e.g. could begin to exploit economies of scale to compete on pricing and improve
their deposit mobilization capabilities, which could positively affect interest rates. The Central Bank of Nigeria
(CBN) has not formulated a model that will reduce interest rate, inflation and stabilize the exchange rate.
However, a time series analysis was adopted for 40 years (1970- 2010).The Error Correction Modelling (ECM)
was adopted to reconcile fluctuations or changes both in the short and long run between the variables. The result
shows that due to the ability to estimates the parameters of Error Correction Mechanism (ECM), which is
generally consistent, sufficient, significant and negative. The non-zero coefficient of ∆INTt and INFt in both
ways, if statistically significant, will indicate a short-run causality from ∆INTt to ∆Gcft as well as ∆INFt to
∆GDPt. The paper recommends that pragmatic approach needs to be adopted to ensure that the lending rates are
reduced to single digit in order to reduce production cost, high unemployment rate and encourage Foreign Direct
Investment (FDI). The monetary policy rate (MPR) at 12% (CBN, 2013) is too high for a developing economy
such as Nigeria because it will have a negative impact on the naira exchange rate. Monetary and fiscal policies
remain necessary and sufficient conditions for attaining a realistic interest rate performance. Interest rate
management in a depressionary economy needs regular fine-tuning of relevant instruments by the monetary
authorities.

1. Introduction
The financial systems of most developing nations have come under stress as a result of the economic shocks of
the 1980s and early in 2008 in Nigeria. Financial repression shows through indiscriminate distortions of financial
prices to reduce the real rate of growth and size of the financial sector to non-financial magnitudes. It is obvious
in recent times, that financial repression has retarded the development process as envisaged by (Shaw, 1973;
Ephraim, 2001). Undoubtedly, governments’ past efforts to promote economic development by controlling
interest rates and securing “inexperience” funding for their own activities have undermined financial
development. Capital formation can lead to increase in size of national output, income and employment thereby
solving the problems of inflation and balance of payment and making the economy free from the burden of
foreign debts (Agagi 1990).
The strains on inflationary pressure on a developing economy can be removed to a considerable extent by
increased capital formation, in the long-run, it augments the supply of goods, control inflation and brings
stability in the economy (Khoury 1983). Capital is always formed when some resources available in the current
period are devoted to the creation of intermediate goods (which can be used for further production) or to the
pilling-up of inventories of final goods which are not intended to be consumed during the current period. The
essence of capital formation is a postponement of consumption. Consequently, most countries, both developed
and developing have taken steps to liberalize their interest rates as part of the reform of the entire financial
system (banks and non- banks) as witnessed in 2008 and recently in 2011 in Nigeria. Such liberalization
represents a policy response, encompassing a package of measures to remove all undesirable state imposed
constraints on the free working of the financial markets. (Killick & Martin, 1990). The reform in the financial
market and banks remain a consistent force for the development of less developed economies (Kent & John,

2008). During the early eighties, Nigerian economy witnessed such financial repression, during this era, rigid
exchange rate, interest rate and bank assets controls resulting in low direct investment. Monetary and credit
aggregates moved rather slowly, which permits continuous pressure on the financial sector, which in turn
necessitated a reform of the financial system, in addition, deregulation of financial markets and banks has been
channeled towards competitive actions, but greatly accompanied with increased regulation over the soundness of
financial institutions’ positions (Soyibo & Soyode, 1992; Kent & John, 2008).
The economic reforms, especially what came to be tagged structural adjustment programs (SAP) in Nigeria in
1986 till today, have almost been mounted in response to national financial distress whose foundation could be
traced to macroeconomic distortions as well as fiscal and monetary policies mismatch. While such distress
becomes obvious, the external debts have just increased to $6bn in 2013. Distortions are often evident in the
pursuit of unsustainable fiscal, monetary and exchange rates policies (World Bank, 2006). The situation has
forced many financial and non-financial institutions to relocate to other economies (off-shore) where the
environment is even weaker and uncertain (Hajela, 2009). In general, several analysts believe that economic
mal-adjustment is associated with policy pursuits which depart from free market pricing policies (Ray 1996).
Though, deregulation of financial markets and banks in particular has been a consistent force in the development
of the financial system in developing countries (Kent & John, 2008). Economic reforms are therefore seen as
pursuits of fiscal reforms and market deregulation, which focus on extensive privatization of state owned
enterprises as well as deregulation of financial and foreign exchange markets, with the government limited to
provision of the right enabling environment for a private sector led growth. The heart of economic reforms is the
need to address a two-fold task: restructure or get policy incentives right as well as restructure key
implementation institutions Financial sector is that aspect of economic reforms which focus mainly on
restructuring financial sector institutions (regulators, operators and policymakers) via institutional and policy
reforms.
The other parts of the paper is further divided into four sections. Section 2 emphasizes on empirical literature
review. Section 3 focuses on methodology. Section 4 highlight empirical results and section 5 makes the
concluding part.
2. Literature Review
2.1 Human Capital and Inflation
Despite the generally acknowledged importance of human capital for economic growth and development,
empirical studies on the effects of inflation on growth have disregarded human capital. It is assumed that the
expected (and often observed) negative effect of inflation on physical capital also apply to human capital. The
view that physical and human capital are equal with respect to their response to inflation. It is very essential to
understand that inflation stimulates human capital formation. Hence, the average per capita investment of time in
education – and therefore the change in average years in Education – is mainly influenced by two variables: per
capita government spending on education and inflation. Higher government spending on education may raise the
productivity of schooling and make investment in education more attractive. Inflation is included as a
determinant of the efficiency with which labour and capital can be employed in production. It is assumed that
inclusion of explanatory variables are average annual consumer price inflation in the period (CBN 2004).
Capital formation refers to the net additions to the (physical) capital stock in an accounting period, or, to the
value of the increase of the capital stock; though it may occasionally also refer to the total stock of capital
formed (Freddy et’al 2003). Thus, capital formation equals fixed capital investment, the increase in the value of
inventories held, plus (net lending to foreign countries, during an accounting period. Although, some blue-ship
companies engage in corporate self-financing- financing from their own reserves or share issues bought by other
corporations. However, most of the largest sources of investment capital consists of financial institutions, not
individuals or households or governments. Financial institutions are mostly owned by individuals, but those
individuals have little control over the transfer of funds (Haynes, 2005). Few individuals own a corporation,
group of individuals can own the public sector (Poterba 1987). The transfer of funds to corporation may not
result in increased output; given an excess capacity and a low rate of return. Corporations may not invest in
funds to expand output, and engage in asset speculation but to obtain property income that boosts shareholder
returns. In reality, more and more local capital value drains to foreign share-holders and creditors. The concept
of “household saving” must also be looked at critically, since a lot of this “saving” in reality consists precisely
of investing in housing, which given low interest rates and rising real estate prices, yields a better return than if
you keep your money in the bank or invest in financial securities (Glomm & Rayikumar, 2001).
Recent models of growth, beginning with Romer (1986) and Lucas (1988), as well as the balance of empirical
work emphasize that human capital investment is an important factor that contributes to long-run growth. It then
comes as no surprise that models on inflation and growth have gradually taken into account human capital as an
endogenous variable. In general, these monetary growth models predict either neutral or negative effects from

inflation on human capital investment. Pecorino (1995) specify two-sector models where money enters as a
factor of production in the final goods sector, i.e. the sector that produces consumer and physical capital goods.
Money does not enter in the “education industry”, i.e. the sector where new human capital is being produced
total labour supply is exogenous. There is no labour-leisure choice. Wang and Yip (1992) obtain neutral effects
from money growth and inflation on human capital and output growth. A crucial element is their Lucas-Uzawa
assumption that the production of human capital does not require physical as an input. Pecorino (1995) follows
King and Rebelo (1990) and includes physical capital in the human capital production function. Higher money
growth and inflation now undermine output growth and human capital. The higher inflation reduces the marginal
product and the output of physical capital. A smaller physical capital stock has negative consequences for the
return and output in the human capital sector. Extending Chang (2002) obtains negative effects from inflation
and money growth by including real as an input into human capital production. Neutral effects of inflation on
human capital and growth can be obtained if the cash-in-advance constraint only applies to consumer goods and
if labour supply is exogenous. Otherwise, inflation effects are typically negative. Labour can be employed
neither in the production of goods for firms nor in new human capital production outside the market. Inflation
reduces the effective return to working since- due to advance payment philosophy – income currently incurred in
the period cannot be exhausted before the next one is received. This encourages people to prefer leisure to labour;
the effect is that goods production and human capital production will decline sharply. Pecorino (1995), assets
that there are two sectors, both employing physical and human capital. Under an advance payment constraint,
higher money growth produces a direct negative inflation tax effect on the rate of return to capital, discouraging
capital formation. Relevance of the inflation/human capital relationship, puts the effect of inflation on the
allocation of human capital at the center. In a high inflation period, talented and brilliant person(s) may be
diverted to activities in the financial sector and away from teaching. This may undermine the productivity of
schooling for youngsters and – as a consequence – the time they allocate to building human capital. Instead of
education, these youngsters might prefer financially motivated activities themselves. An important result is that
inflation may undermine total factor productivity in production, e.g. by forcing economic agents to economize
on the use of money or by disrupting the crucial role of the price mechanism in the efficient allocation of
resources (Adeoye, 2002).
2.2 The Roles of Interest Rates in the Economy
The basic function of interest rate in an economy in which individual economic agents decision as to whether
they should borrow, invest, save and/or consume are summarized by the I.M.F (1983) under three broad aspects.
Interest rate is regarded as return on financial assets serves as incentives to savers, making them differ present
consumption to a future date. Interest rate perform various important functions in the sense that they influence a
broad range of economic decisions and outcomes. They are similar in scope to the influence of other economy
wide prices such as exchange rates and the basic wage rate. As the reward for accumulating financial asset and
foregoing, current consumption, interest rate influences the willingness to save. In this connection, interest rates
affect the availability of saving and to the extent that deposit rates vary depending on the maturity of the
financial assets. They also influence the allocation of current savings among other assets (Somoye, 2005).
Interest rate being a component of cost of capital, affect the demand for and allocation of loanable funds. The
lending rate changes affect the cost of capital, which influences investors; willingness to invest in machine and
equipment (real investment). In this way, the level of interest (lending) rate influence growth in financial
instrument; output and employment. In other words, as a cost of capital, interest rates influences the demand for
loanable funds by different types of borrowers, including, private economic agents. The domestic interest rate in
conjunction with the rate of return on foreign financial assets, expected change in exchange rate and expected
inflation rate determine the allocation of accumulated savings among domestic financial assets, foreign, assets
and goods that are hedged against inflation. The speculative movement of funds into/out of
domestic/international assets depends on the relative levels of interest rates and whichever is appropriate among
exchange rate, inflation rate and foreign interest rates.
Interest rates are considered by the CBN (1997) are said to be crucial in financial intermediation, which involves
transferring funds from surplus unit to deficit unit. Interest rates have an impact in gauging financial market
conditions, being the major tool of monetary policy. There is consensus that financial development has had a
significant positive impact on the growth rates of countries. The increase in interest rate (MPR- 12%) is as a
result in the response to the uptick in food inflation, and its reduction will lead to reduction in core inflation,
Gross Domestic Growth, the decision was as a result of structural nature of inflationary pressures (CBN 2013).
Similarly, Ghani (1992) provides evidence to the effect that the initial level of financial development is
positively associated with a country’s GDP growth rate. A country that starts with a more developed financial
system tends to grow faster because it can efficiently make use of more resources- encouraging, controlling and
managing economic reform, financial innovation and globalization in the financial markets and banks. This is

achieved through better evaluation and monitoring of financial institutions, lower transaction costs for financial
intermediation and externalities generated from information selected and processed in financial markets (Jhingan,
2005). However, Oyejide (1994) argues that the financial system and the real sector could both grow together in
a mutually reinforcing way or both stagnate and decline. Though, to achieve the laudable objective of growth
and development, there is need for consistency in economic policy and political stability which are sine qua non
in nature. Therefore, risk affects savings decision because the future remains unknown. If you are afraid that
your savings will not be there when you want to withdraw them, you will need a very high interest rate to
overcome the risk of loss. On the other hand, if you are confident that your savings will be there in future you
may be willing to save at a low interest rate. The increase in interest rate in Nigeria will continue to promote
excess liquidity, which may have negative effect on the whole economy. The cost of funding begins to increase
in all sectors, particularly the real sector. This idea of interest rate increase will continue to promote inflation and
predict weaker naira (Boyo, 2013).
2.3 Inflationary Trend in Nigeria
The Nigerian economy seemed to have experienced moderate inflation prior to the advent of the Structural
Adjustment Programme (SAP) in 1986. Since then, the unfavourable consequences of inflation in the country
have assumed intolerable dimensions. Inflation per se is not bad as studies have shown that there exists a
positive relationship between inflation and growth in the short run (Afolabi & Efunwoye, 1996), but the problem
lies in a country continually having high inflation rates. In Nigeria, high inflation has been found to have
undesirable consequences on economic parameters. According to Ekpeyong (2005), inflation in Nigeria has
remained high, thus, keeping the real interest rate negative most of the time. Inflation remaining uncontrollable
and the real interest rate remaining negative most of the time, manufacturing costs have gone up savings and
investment have remained low, and the economy has experienced low industrial capacity and weak social and
industrial infrastructure. CBN (2010) observed that high rate of inflation in the economy would reduce demand
for bank’s financial assets and hence, impair the process of financial intermediation in the banking sector as
deposits would move from the banking system into real estate and inventory speculations among others. As at
2012, the inflation rate remains at 12.4% (CBN, 2013), it shows that the continuous increase in interest rate will
automatically promote excess liquidity, increase in money supply in circulation, inflation and inevitable burden
of rising subsidy payments.
2.4 Structure of the Nigerian Banking System
The banking system all over the world plays fundamental roles in the growth and development of an economy.
These vary from country to country depending on the economic, political and the legal system within which the
banks operate. Banks as financial institutions perform intermediation roles generally through the mobilization of
resources from the surplus units for and channeling of same to the deficit units for productive activities within an
economy designed to ensure a more efficient resources allocation and utilization. This of course is most
important function of banks, especially in a developing country like Nigeria where resources available are
generally insufficient to meet the development needs of the economy.
Again as clearing and settlement institutions, banks constitute useful channel in the payment system and the
medium through which the effect of monetary policy are transmitted to the rest of the economy. The ability of
banks to perform these roles efficiently is dependent on the health and the sophistication of the banking system
as well as on the level of development of the financial system in general (Adekanye, 1996). Being the economic
life wire of a nation and the nature of services they provide, banks have had to be subjected to close scrutiny by
the monetary authority not only to ensure the efficient functioning of the system but to remove all the unethical
practices that are capable of causing disruptions in the macro economy. This explains why the central banks all
over the world pay special attention to the banking industry, including the economic growth process. The
Nigerian banking system is made of the Central Bank of Nigeria (CBN) – the apex bank. Twenty-two main
stream Deposit Money Banks (DMDs) with 5436 branches spread across the country. In addition, there are 871
micro finance banks, 82 primary mortgage institutions and five developmental banks to take care of small
depositors and other special interest group (CBN, 2009). Before the introduction of Universal Banking (UB) in
2001 the DMDs were segmented into commercial and merchant banks for retail and wholesale banking business,
respectively (Ojo, 2004). The deposit money banks (DMDs) are the major players in the money markets with
growth in the bank investments portfolio exerting significant influence on performance of the economy.
3. Methodology
Most countries, both developed and developing have taken steps to liberalize their interest rate as part of the
reform of the entire financial system. The Granger causality test is used to determine the direction of causality
between Gross Capital formation and Gross Domestic Product (GDP) in an emerging market (Nigeria inclusive|).
However, it is very crucial that since the lack of understanding of the exact causality may result to wrong
specification and consequently giving an erroneous inferences concerning the two variables. The model for John

Weiner Granger causality test (as described by Granger, 1969) is hereby explained below:
Let Gross Capital formation (GCF) and Gross Domestic Product (GDP) as well as Interest Rate (INT) and
inflation (INF) being two time series with zero means. Recall, granger causality modeling is very sensitive to the
lag length. The simple causal model is:
n n
INFt = ∑αi: INTt - i + ∑ βj INFt – j + U1t ……………… (1)
t = 1 j = 1
n n
GDPt = ∑λi: GCFt – j + ∑δj GDPt – j + U2t ……………… (2)
t = 1 j = 1
Where Gcf = Gross Capital Formation
GDP = Gross Domestic Product
INF = Inflation Rate
INT = Interest Rate
U1t and U2t = disturbance variables/uncorrelated variables/white noise error term
Both αi and βj are estimated coefficient on lagged Interest rate (INT) and Inflation rate (INF) in
equation (i)
Also, λi and δj are estimated coefficient on lagged Gross Capital Formation (GCF) and GDP in
equation (ii)
n =: lag length (It can be infinity but in practice, due to the finite length of available data, ‘n’ is thereby
assumed finite and shorter as a given time series.
The Granger Causality Test above explains that interest rate (INT) is causing Gross Formation (Gcf)
provided some αi is not zero (o). Also, in some vein; Gross Capital formation (Gcf) is causing Interest Rate (INT)
if δj is not zero (o) i.e. mathematically, αi = δj # 0. Therefore, if both of these events exist, then serial to be a
bilateral relationship between Gross Capital formation (Gcf) and Interest Rate (INT).Owing to the peculiarities
of the world economic problems which engendered its metamorphosis to its present status, analysis at most times
becomes inconclusive without any empirical results. The corollary is the need to uplift the world problem to a
quantitative stage to demystify the complexities in order to arrive at a valid and testable empirical outcome. This
chapter puts their conjecture to the empirical test and examines the alternative explanation that, the economic
growth and development has a significant role to play in the real sector, via the low interest rate regime.
Theoretically, most of the economic variables that are shown in time series econometric models are non-
stationary. Therefore, it is very essential and of great importance to carry out the Unit Root Test for stationarity.
According to Dickey and Fuller (1979) and Phillips- Perron (1988) argued that in order to avoid the spurious
regression problem that may arise from regressing a nonstationary time series on one or more nonstationarity
time series, there is need to transform nonstationary time series to make them stationary which can be in form of
difference stationary or trend stationary Gujarati (2003). In order to determine if the time series data is stationary
or non-stationary, the widely used Augmented Dickey – Fuller (ADF) test (Dickey and Fuller 1979) also Phillips
and Perron (PP), Phillips – Perron test are employed. Hence, the null hypothesis of a unit root is rejected (Type 1
Error) against the one-sided alternative if the t-statistics is less than the critical value.
INTt = αi INFt–i + Vt …………………………. (3).
GCFt = λi GDPt–i + V1t ………………………… (4)
Where: = first difference operator
Gcf = Gross Capital formation
INT = Interest rate
GDP = Gross Domestic Product
t – i and t – j = Lag values
αi and λi are estimated coefficient lagged INT and INF in equation (3) and (4) respectively.
Vt and Vit are disturbance error term.
From equation (3), if αi = 0, interest rate is non-stationary and also equation (4), where λi = 0 inflation rate will
be non-stationarity time series on explanatory variables are integrated order I (1). Also, where outcomes of
interest rate and capital formation as well as Interest Rate and Inflation Rate are not co-integrated as shown in
equation (3) and (4) above, therefore αi and λi are significantly different from zero (individually integrated).
Recall, the regression of a non-stationarity time series on another non-stationary time series may produce a
spurious regression. Therefore, it is essential to affirm whether the variables can be co-integrated by carrying out
configuration test. According to Granger (1986); Dickey et al (1991) and Eagle and Granger (1987) explained a
linear relationship of two or more no-stationary series, which may be stationary. Where such a stationary that is,
I (o), a linear relationship exists, the non-stationary that is, I (1) however, with a unit root), therefore time series

are expected to be co-integrated. The stationary linear relationship is called co-integrating equation and
explained as a stable Long-run relationship among the non-stationarity time series variables. In addition, the
short-run dynamics that might cause the relationship not to be established in the short-run. Though, the co-
integration test can be conducted through Engle and Granger (1987) – Augmented Engle – Granger (AEG) test.
In this situation two-step test and maximum likelihood method developed by Johansen (1995); Sargan and
Bhargara (1983). For the benefit of this study, Johansen technique would be adopted because less errors are
involved since only a step is undertaken instead of the two steps recommended by Engle-Granger technique.
n
INTt = βo INFt - i + ∑ INTt – j + Vp ……………… (5)
j = 1
n
GCFt = δo GDPt – j + ∑ GDPt – j + V1p ……………… (6)
j = 1
Where
βo and δo are estimated coefficient of INF and GDP in equation (5) and (6).
VP and V1P = the new disturbance error term.
t-i and t – j are lagged values
Note: Other variables have been mentioned earlier.
The Pseudo t-value associated with βo and δo are the ADF and PP statistics. The null hypothesis of non-
co-integration is rejected, if the estimated ADF and PP statistics are found to be greater than its critical value at 1
or 5 or 10 percent level of significance.
To be co-integrated, both INF and INTt as well as GDPt and GCFt have some order of integration
respectively. Engle and Granger (1987) and Granger (1986).
According to Sargan (1984) and Engle and Granger (1987) showed that the Error Correction Mechanism (ECM)
was developed by means of reconciling the dynamism of the short-run behaviour of an economic variable with
the long-run behaviour. However, in the short-run there may be disequilibrium. It is believed that in the long-
term, there would be equilibrium or relationship between Interest Rate and Inflation rate could be ascertained.
Being individually, non-stationary a linear combination of two or more time series can be stationary. The Engle
– Granger, Augmented Engle-Granger and Co-integrating Regression Durbin Watson test can be used to find out
if two or more time series are co-integrated (Gujarati, 2003).
Where
V2p and Pv are new random disturbances error team.
Note: Other variables have been mentioned before.
Where Gcft and INTt are found to be co-integrated, therefore there must exist an associated or equilibrium error
correction Model (ECM) according to Engle Granger (1987).
Note other variables have been mentioned before.
σo and σ1 are estimated coefficient on lag INTt and Gcft as well as lag GDPt and INFt on equation (vii) and (viii)
respectively. Where the estimated coefficient σo and σ1 is significantly different from zero, then Gcft and INTt as
well as GDPt and INFt will have long run relationship respectively. However, due to the ability of ECM to
induce flexibility by combining both the short-run and long-run dynamism in a united system. Also the estimates
of the parameters of Error Correction Mechanism (ECM) are generally consistent, sufficient, significant and
negative. The non-zero coefficient of ∆INTt and INFt in both ways, if statistically significant, will indicate a
short-run causality from ∆INTt to ∆Gcft as well as ∆INFt to ∆GDPt. The statistically significant non-zero
coefficients of ∆Gcft as well as ∆GDPt will indicate bi-causality or feedback to ∆Gcft.as well as ∆GDPt. from its
own lagged values respectively. It must be noted that where there is no co-integration, the error correction model
may be estimated in the short run.
The model for John Weiner Granger causality test (as described by Granger, 1969) is hereby explained below:
Let Gross Capital formation (GCF) and Interest Rate (INT) be two time series with zero means. Recall, granger
causality modeling is very sensitive to the lag length.

n = lag length (It can be infinity but in practice, due to the finite length of available data, ‘n’ is thereby
assumed finite and shorter as a given time series. However, the Granger Causality Test above explains that
interest rate (INT) is causing Gross Formation (Gcf) provided some αi is not zero (o). Also, in some vein; Gross

Therefore, if both of these events exist, then serial to be a bilateral relationship between Gross Capital formation
(Gcf) and Interest Rate (INT).Owing to the peculiarities of the world economic problems which engendered its

The corollary is the need to uplift the world problem to a quantitative stage to demystify the complexities in

4. Empirical Result
From table 11 and 12 below shows the time series behaviour of each series as presented earlier using the
Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) test show over-whelming proof of the existence of
non-stationarity (differencing the non-stationarity) in the series and that the variables are integrated of order 1(1)
as shown in the decision ‘column’. Though, both the ADF and PP test show that the null of non-stationarity will
be rejected (Type 1 error) for all the variable at levels. With table 13 below, which shows the co-integration test,
which are conducted according to rank tests. The trace statistics suggest the existence of only one co-integrating
at the 5% critical value and the test indicates co-integration at the 1% critical value for the model, as shown. This
further explains that non-stationarity time series on explanatory variables; I (I) with linear combination or
relationship in stationary time series; I (0) could only be co-integrated at 1% and 5%. To ascertain for co-
integration between the contemporaneous financial sectors variables in levels, the long-run of interest rate on
capital formation which exists in emerging market is estimated by the model in table 14 below.
The model shows that explanatory variables are quite able to explain the variations during the guided interest
rate regime. However, the explanatory variables are estimated at 74.0% variations in the proxies for increase in
Gross Capital formation during the guided interest rate regime/post-reform era more than in unregulated and
regulated interest rate regime (pre-reform era). The Pre-reform era represents zero (o) while post reform era
represents one (1). With the Gross Capital Formation (GCF) with higher values of adjusted R2
i.e. 74.0%.
However, the high values of F-statistics in the model indicate a significance of the explanatory variables. But the
estimated coefficient of interest rate is negative with a very low Durbin Watson. But the long-run model shows
that only Gross Capital Formation (GCF) is significant in explaining the guided interest rate regime / post reform
era. However, an appreciate level of Gross Capital Formation in the post reform era or guided interest rate
regime show how monetary policy implementation framework was introduced to remove volatility in inter-bank
rates and improve the transmission of monetary policy actions.
With reference to the results on the co-integration test, over-parameterized interest rate in the emerging market
was estimated. Every variable was set at one (1) lag. However, dummy variables were used to capture the post
reform era. As stated earlier the pre-reform era i.e. (unregulated and regulated rate regime) is represented with
value of zero (0), while the reform era is represented with value of one (1). To commence with over-
parameterized models as stated in table 15-18; which is then tested down until the preferred parsimonious
models as stated in table 16 is derived at. The parsimonious encompassing models explained that based on
Akaike Info Criterion (AIC) or Schiwarz Info Criterion (SIC), the re-parameterize model ensures that
insignificant variables are excluded until Information Criterion (IC) start rising as depicted in table 16. In order
to ascertain a goodness of fit test, the models that emerged is slightly significant to the over-parameterized ones.
The dynamic parsimonious result for model, it shows that the explanatory variables accounted for 20.3%
variations in the level over the entire sample period. The findings show that 43.6% errors are corrected every
year as depicted in Table 16 below. Though the Error Correction Term (ECT) must be negative and significant.
5. Conclusion
This study helps to examine the impact of interest rate on the development of Nigerian economy. It was
discovered that interest rate will automatically assist in the mobilization and utilization process of financial
resources in order to achieve a desired economic growth and development. The paper discovers that Nigerian
Government aspiration of 10% GDP growth rate appears to be rather too ambitious because other economic
indicators such as interest rate, inflation rate, money supply and exchange rate have not being well considered
during monetary policy committee meetings. The improvement recorded could be attributed to the slight high
purchasing power in the country during the period, as well as the application of monetary policy measures by the
CBN to mop up excess liquidity in the economy. The relative instability recorded in the foreign exchange market
since Stock exchange collapse early 2008, coupled with tight fiscal regime maintained by the government,
contributed greatly in increasing the level of inflation. Interest rate performance remained largely unchanged
since the beginning of the year as the rates continue to rise abnormally and interest rate has not come down to a

level that investors generally desire. With the bank consolidation and recent reform, current cost and access to
funds are still major concerns to investor s/ businesses in the country. The lending rate, 19-25% (CBN 2013),
remained high and discouraging to intended investors, as cost of funds continue to rise. This has a grave
implications for the global competitiveness of the real sector. The unemployment and poverty level was still high
in the country in spite of the implementation of NEEDS (National Empowerment Economic Development
Strategy) agenda and the tremendous growth in the telecommunication sector, has provided jobs for a good
number of Nigerians. The last few years have witnessed reductions in public-sector credit. There is need to
pursue to a logical end in order to boost and encourage private sector confidence that will show that Nigerian
economy is indeed pursuing private sector-led economic policies by reducing the interest rate (MPR) to a single
digit. The current economic reforms are desirable and should be sustained since progressive and democratic
societies world over undertakes such exercises. A well-developed financial market and banks are prerequisite for
the use of interest rate as a major monetary instrument. Our financial market will be efficient only if government
controls prices in the market such as interest rates and transaction fees. The government should attempt to
regulate entry and exit to curtail monopoly and ensure safety regulations to protect the interest of all parties and
create confidence in the public. Government should enact policies that can cure disease of too much cash, the
variables of interest rate and inflation rates will reduce to support industrial regeneration, stable exchange rate
and increase the value of the local currency. The fact remains that 12% monetary policy rate (MPR), 9.1 %
inflation rate, and broad money (M2) at 4.44% (CBN, 2013), have put more pressure on the exchange rate and it
will be difficult for the economy to grow within a weak domestic environment and the recent shock that affected
international financial markets. The high interest rate will lead to excess liquidity which may result into
unnecessary credit expansion.Therefore, the wide spread between deposit and lending rates should be reduced
and narrowed down both into a single digit. Finally, the Central Bank should adopt non-negotiable dollar
certificates for the payments of monthly allocations derived from dollar –revenue, lower interest rate, inflation
rate and strong purchasing power of the local currency (naira) will be realisable. If interest rate is not control
now (short –run), it may be more than two digits in the future (long –run), which may result to a negative impact
on the economy. It is highly essential for government via Central Bank of Nigeria (CBN) to adopt a continuous
re-examining credit allocations and interest rate policies as a result of its negative effect on Foreign Direct
Investment (FDI) and the real sector, because interest rate remains the major tool for effective monetary policy,
determination of financial markets and banks performance. The result shows that the increase in interest rate may
lead to increase in inflation, high cost of funds, increasing in domestic debts, weaker exchange rate, rising
unemployment particularly among the youths and poverty in Nigeria
