1. Introduction
Several researches have been conducted to study the impact of different macro-economic variables and
their influence on government expenditure. By using different statistical tools researchers have examined that
how money supply and exchange rate influence the government expenditure. Few other studies also conducted
work on the quarterly time series data to examine the long run equilibrium association between the
macroeconomic variables.
Friedman (1978), Blackely (1986) Ram (1988) suggested that the increase in government revenue plays a
vital role in increasing the government expenditure. Akhtar and Abbas (2002) drawn the conclusion that
exchange rates might differ due to decrease in government expenditure. Guffey (1985) concluded that money is
not neutral, because it is the monetary policy that heavily effects inflation which will again adversely affect the
economic growth. Studying over 100 countries it is suggested by Landau (1983) that growth rate and
government expenditure are negatively related. Grier and Tullock (1989) use pooled regression on five-year
averaged data in 113 countries to analyze the relationship between cross-country growth and various
macroeconomic variables. They find that the mean growth of government share of GDP generally has a negative
impact on economic growth. This finding implies that an increase in the government size as measured by a share
of government expenditures to GDP hampers economic growth. Barro (1990) also discovers the negative

relationship between the size of government and economic growth. Miller and Russek (1997) indicate that debt-
finance increases in government expenditure retarded growth.
It is evident from previous researches that money supply has an impact on government expenditure as
well as economic growth. By taking this hypothesis this research made an attempt to study these variables and
their relationship in Pakistan economy in time period of 1970 to 2012. Also it will investigate that what role is
played by exchange rate in government spending and will try to find out its nature.

2. Literature Review
2.1.Theoretical Background
The theoretical relationship between government expenditure and money supply and exchange rates is
very important to understand. According to monetarist theory it is assumed that changes in money supply exert a
dominant influence on changing patterns of government expenditure. The public’s demand for money is another
important part of the relationship between money supply and government expenditure1
.
This should be kept in mind that if Rs. 1 bought yesterday what Rs. 2 bought today then there will be a
need for Rs. 2 to sustain the purchasing pattern. That’s why the increased government expenditure is a false
increase in money supply because it is the deficit that government needs to finance, a reserve of money is there
for loans for the government from State Bank of Pakistan and other financial institutions. Now, the exchange rate
is also a major macroeconomic variable that if left ungoverned can be very threatening in fiscal policy making2
.
Literature that was analyzed for this research paper shows little or no sign of exchange rates impacting
government expenditure, which is why this research paper might throw some light on the nature of relationship
between exchange rates and government expenditure.
2.2.Empirical Studies
Sola and Peter (2013) examined the money supply and inflation rate in Nigerian economy. Variables
that were used are inflation rate, money supply, interest rate, exchange rate, oil revenue, and government
expenditure. Time series data has been used for the study purpose from 1970 to 2008. Econometric tests like
Vector Auto-Regression (VAR), Augmented Dickey-Fuller, and Granger Causality were used. A positive
relation between money supply and inflation rate is found also causality test shows unidirectional causality
between exchange rate and inflation rate, interest rate and inflation rate, also money supply and government
expenditures.
Ali et al (2013) enquired the impact of government expenditures on economic growth during different
democratic and dictatorial eras. The data is from the year of 1972-2009. Different sub-categories of government

expenditures are taken as variables. Data analysis is carried out by using Auto-Regressive Distributed Lag
(ADL). It is concluded that development expenditure heavily support economic growth and it’s also validates the
assumption of that public and private investments are complementary to each other.
Georgantopoulos and Tsamis (2012) investigated the interrelationship of money supply, government
expenditure, prices, and economic growth in both short-run and long-run in Cyprus. For this purpose the variable
used are M2 (broad money), CPI, and Real GDP. Annual data is gathered form year 1980 to 2009. Error Correction
Model (ECM) and Johnson co-integration techniques were used to analyze the data. Findings show that inflation
effects economic growth very badly, and this is recommended to control government expenditures that increase
aggregate demand and shifting of these expenditures to increase aggregate supply.
Husnain et al (2011) questioned the interrelationship of government spending, foreign direct investment,
and economic growth in Pakistan scenario. The data is collect from 1975 to 2008. Four variables were taken for
analyses that are capital (K), labor (L), foreign direct investment (F), and total factor productivity (A). It is
concluded that one most contributing factor in Pakistan’s economic growth is trade openness and the existing
government expenditure structure is not in accordance to the economic needs it must be reorganized.
Mehmood and Sadiq (2010) examined the effect of government expenditure in the form of fiscal deficits on
level tax revenues. Using controlled variables poverty, government expenditure, remittance, private investment, and
secondary school enrollment from 1976 to 2010 annually. For long-run relationship co-integration test is applied and
for short-run error correction model is used. The Augmented Dickey-Fuller results show that poverty reduces due to
public spending thrift and remittances. Also public spending will increase aggregate demand in long-run.
Muhammad et al (2009) examined the relationship among government expenditure, M2, inflation and
economic growth in Pakistan. Data was collected from the year 1977 to 2007. The method used for this purpose was
Johnson co integration test to check the long term relationship, Granger causality test also has been used. The
research findings revealed that there exists a negative relationship b/w public expenditure and inflation with
economic growth. Also M2 is positively related to economic growth. The only reason that was determined for
negative relationship by the research was due to cost push inflation. The research suggested that growth rate of
money supply should be controlled. And governments must try to restrain from financing deficit by borrowing from
central bank.

Iqbal and Malik (2009) studied the relationship between government expenditure and taxes for the case of
Pakistan using annual data from 1961 to 2008. The method used Vector Error Correction Model (VECM), granger,
co-integration model, Augmented Dickey-Fuller and Johnson Co-integration approach. The analysis shows that in
case of Pakistan budget deficit and debt have close relationship. But the budget deficits have no impact on the
behavior of government taxes and expenditure in Pakistan. It means in case of Pakistan results found that taxes and
spending decision have no relation and there is no long run co-integration between taxes and expenditure.
Adrison (2002) explained money supply and government expenditure on economic growth in Indonesia
to check the asymmetric effect. Money supply and government expenditures are used as variables to run the
tests. The data collected is quarterly from 1980-1997. The technique that has been used is TARCH (Threshold
Auto Regressive Conditional Heteroscedasticity). The regression model showed that the government expenditure
has an asymmetric effect on economic output and also that money supply is not a contributing factor in inflation.
It is recommended that reallocation of government spending more towards developmental programs.
Albatel (2000) attempted to instigate the relationship between government expenditure and economic
growth in Saudi Arabia. GDP, government expenditure, government consumption, private investment, oil revenues,
and other revenues are variables upon which data is collected from 1964-1995. Method that is used to examine the
data is Augmented Dickey-Fuller (ADF). On the basis of results it is concluded that government should continue
providing economic infrastructure and social activities and on the other hand advise and encourage the private
investors to play a meaningful role as well.
Hsieh and Lai (1994) queried the relationship of government spending and economic growth in G-7
countries. The data is collected on Real GDP and share of government expenditure on goods and services from
1885-1997. Data analysis is done by using ADF and Phillip-PerronZt(q) test. The findings proved that relationship
between government spending and economic growth can vary across time. But still government spending is the only
best way possible for growth in economy.

3. Methodology
3.1.Modeling Framework
To estimate the effect of money supply (MS) and exchange rates (ER) on government
expenditure (GE) in Pakistan following model is used:
GE= α + β1MS +β2ER + ε
Hₒ1 = MS does not affect GE
Hₒ2 = ER does not affect GE
Where GE is the percentage of GDP of Gross National Expenditure is taken, MS is taken as Quasi
Money M2 as percentage of GDP and ER is taken as amount in rupees against 1 US dollar; Data for all
research variables is from the time period of 1970 to 2012. Data for research variables under
consideration is taken from World Bank3

MS -0.367716 0.0079
ER -0.058903 0.0045
It is shown that MS and ER have negative relation with the dependent variable GE, meaning if
MS increase by 1 unit GE will decrease by 0.3167 units and if ER increase by 1 unit than GE will
decrease by 0.0589 units.
4.1.2. Stationary Analysis
So to check the trend in the data stationary analysis is conducted for verification. Unit root test is
used for stationary analysis with Augmented Dickey-Fuller statistic. The hypothesis is that there is a trend
in data or the data is non-stationary.
Unit root test has been performed for all variables with level and 1st
difference, and 2nd
difference is also used where 1st
difference shows the contradiction. The test has been run for individual
intercept and individual intercept & Trend. The results have been reported in table 2.

4.1.3. Heteroskedasticity Test
Heteroskedasticity often arises in cross sectional data but the data taken for the research purpose
is already time series. The P value is 0.121 it means that there is no existence of heteroskedasticity in the
data.
4.1.4. Auto Correlation LM Test
When computed, the resulting number can range from 0 to 4. An autocorrelation of less than 2
represents perfect positive correlation, an increase seen in one time series will lead to a proportionate
increase in the other time series, while a value of greater than 2 represents perfect negative correlation, an
increase seen in one time series results in a proportionate decrease in the other time series4
.
The probability value is 0 it means there exist positive autocorrelation in the data. The removal
of auto correlation can be viewed in appendix.

is ±5%. All the data variable variables are under the significance
level showing that data is stable.
To verify the previous CUSUM SQUARE test is carried out here
we can see that the provided data is crossing the significance
level of 5% somewhere in year 1997 or 1998 which is not
required so as to remove it we take the help of Chow’s breakpoint
test. (see appendix)

It is found out that there is no co-integration between the said variables government expenditure, money
supply, and exchange rates. At level “None” the p-value appeared to be 0.0212 or 2.12% less than 5% significance
level. So we reject Hₒ that says variables are co-integrated.

It is evident from the causality test that money supply and exchange rates both combined are not
causing government expenditure. But, it is the government expenditure that is causing money supply and
exchange rates.

5. Conclusion
On the basis of data analysis the study is able to conclude that money supply and exchange rates are
negatively affecting government expenditure. Using the annual data of the period 1970-2012, we found that there is
negative relationship between money supply and exchange rates on government expenditure in long run.
First of all, we have to understand that change in money supply is not the only way of financing
government spending, but for past several years there has been a lot of pressure given on central bank borrowing,
plus borrowing from international financial institution have rapidly change Pakistan’s economic positions. Secondly
a country’s economic performance can be judged by its exchange rate values, one can realize the fact that the more
rupees depreciate then more money is required by the government to pay the debts and run the economic operations.
Whatever the reason is government must need to curtail its expenses and find some other solutions rather
than burdening it’s on economy. Some of the policy recommendation that government authorities need to consider
are a follow:
1. Government expenditure on infrastructure so as to facilitate the economic growth in the long-term scenario.
2. Developing such financial and capital markets that can mobilize savings and channel them to productive use.
3. Investment should be made in international arena in different assets with the aim of having high return rather
than borrowing from World Bank or other financial bodies.
