Conclusion

222
The choice among alternative functional forms rnvolves a compromise among
several crltena including economic theory, goodness of ht and simpiic~ly
defin!te role c~tes which form is an appropriate one for a grven problem Many
econom~sts, researchers who have studied the impact o f various changes of
monetary instruments employed Regression Stahstics to study the ~mpact of
various monetary changes
~u l t l p le Regresslon Technique 1s used In the study to analyze the impact of
changes In varlous monetary Instruments on the growth of deposits, credlt of all
scheduled commerclal banks, GDP, Wholesale Prlce Index and broad money
There is also a need to ellmlnate the posslblilty of var~abies belng auto correlated
~n which case the results may be lneffic~ent Hence, it Is important to rule out the
presence o f auto correlatron Many statistical tests have been developed for
testing the presence of auto co-relation, but amongst all these tests the one
developed by Durbln & Watson appears to be s~mple and reliable Mult~ple
regresslon results tested uslng the Il2 and F Tests, besides the Durbln &Watson
Regressron relatlon prov~des the relatlonsh~p between the dependent variable 'Y'
and one o r more Independent variable/s (X) Regression relationship proves
estlmate of the total variance In the dependent variable that Is assoclated with
varlance In the Independent varlable/s It prov~des a powerful method of provlng
that there 1s a stat~stically slgniflcant relationship between a dependent vanable
and one or more independent var~ables The regresslon results are generally
used to extrapolate for future periods based on the past behavlor of the
dependent variable to movements of the independent variable/s

statlstrcal method used 1s decided basrng on the problem under swdy The
common agreement on the cr~teflon of goodness of fit is rehed upon R~ The higher the value of R2, the larger the Propoition of the dependent vanable

R2 gives the propoftlon of vanation of Y that can be accounted by variation m x The R2 can be calculated as follows

The R2 does not adjust the loss of degrees of freedom n - k and n - 1
~onsequently, the unaausted R2 will become larger and larger as more ~arlables
are added t o a model even though the adjusted R2 may be decreasing because of
the (n - k) Thus the unadjusted may mislead one to believe that additom1
varlubles are useFul in modeling /f when in fact they are not The use of
Unadjusted R2 In fllterlng models that Is too comp/eX Thus to ellmlnate this
lacuna, the concept of aojusfed ~ ~ - e f f i o e n t of determ~natlon Is used. Adlusted
co-efficrent of determrnahon compares ~ z y x to 52y, me ad/uskd CO-effrclent of

The comparison between two or more variable is done throf~gh the F-statistic ( F
stands for the name of Rsher, who Invented thfs stat~stfc) which ~n fact is the
ratio 01' two varfances under study If the two-variance estimates are close to
each other, thefr ratio will approach unity The greater the dlfference between
the two variances, the greater is the valve of F-rabo, which In turn suggests that
the difference between two variances is significant An unb~ased estimator of
common variances may be obtained by poahng together variances of the sub
samples through formula Since the estimates of variances are independent, It
can be shown b a t their ration follows and F-distnbutlon with {(k-1) and (n-k))

One of the basfc assumptions of the linear regression mode/ is tllat the
disturbances (or error) terms are random and follows a normal dlstnbution with
mean 0 and vaflance 4 Thrs implies that the covariance of t/>ese terms are
Zero For a model wtth f lo rmai l~ distrfb~ited disturbances, th,s imp/ies [hat ail
disturbances are independent I n time senes dala, this means serla/
Independence for the drsturbance terms, while for the cross-sechon data tt means
that we are assumrng the disturbance value that 1s drawn for any one unit 1s
uninfluenced by the values drawn for other units However, there are situat~ons rn which the assumptions of serial tndependence In disturbance term may not
exists There could be situations where we make an incorrect assumption of t i ~ e
form of the relatton between the variables For example, suppose we specrfy a
Irner relabon between Y and X, when in fact the true relation ts, say a polynomiai
of order three Even though the dtsturbance term in the actual relation may be
free of auto correlation, the semi-drsturbance term associated wrth the linear
relation contains terms ~n X2 and X3 If there is any serial correlatron In the X
values, that IS, correlation between observations that are adjacent in time order
or any other order o f data coiiection, then we wtll have serial correlation ~n the
composite disturbance term in general, we inciude only certain important
var~abies m the specrfied reiat~on so that the disturbance term represents the
mfluence of omrtted varfabies 1 Durbln and G, Watson developed the test o f
general kind concern~ng auto correlation In 1951 Thls test uses what Is usualiy
referred to as the Durbin-Watson d-stal~strc, and Is based on the sum of the
squared differences in successive value of the estimated disturbance terms
If we have positwe auto correlation, the successive values of the disturbance
terms W I I I tend t o close to another 1.e , posltive value of the et would most likely be followed by another posltlve value et+' Th~s suggests that terms in the
numerator OF d-stabstlc will be relatively small. We would, therefore, expea
POSltlve auto correlation to result In small value for d. Convenely, negative auto
Correlat~on tends to generate large difference between S U C C ~ S S I V ~ value of et,
The slgnal for this type of auto correlation is an unusually large value of d We Compare the calculated value of cj wlth the theoretical value of d; with (n-k)
209
degrees of treedom (K being the number of explanatov variables rncludlng
term) The theoretical value of d is the value wh~ch do would assume
""11 hypothesis Were true I e , if there is no auto correlation
There are two 5tatlstlcs dSsoclated with the DW, dl and du, whlcll are lower and
upper values used to make Inferences The number of observabons, n, the number of Independent variables determines the DW table statistic, (which equals
k-1) The calculated value of DW varies between 0 and 4 with value of 2
denoting no auto correlation and values Of 0 and 4 denoting perfect posttve and
negative auto CO-relatlons, respectively The conclusions associated with
different values of the DW static, the following Inferences resulted when the
b DW is between 0 and dl, or greater than (&dl), reject the null hypothesis and
~nfers that there Is positlve auto to-relat~on
p OW IS between dl and du, or between 4-du and 4 - dl the test is inconclusive
OW is between do and (4- du), accept the null hypothesis and mfer that there
is no auto co-relatlon
b DW is between 4 -dl and 4, there is negative auto co-relation
The above test is widely used in econometric appllcatlons A great advantage of
thls test being that It is based on the estimated residuals Because of thls
advantage, it IS a common practice to report the Ourbin-Watson d.statlst1c along
with other summary statistic/s such as-R', adjusted R2, F-test etc
6.2. Analysis of Data
Many a Changes took place in the monetary instruments during the past 10 years
of econarnlc reforms With an 0bjectiVe of analping the relationship between the
changes in monetary instruments and their Impact on various economic
parameters, collected Quarterly data of monetary aggregates and m0neiaW
instruments as furnished in Table 6 1 The sample period used Is from the first
quarter of 1991 through the first quarter of 2001, so that 41 observations are
available for the estimation The multiple regression model was developed and
With the help of the data and the results were obtained
The estimated regression model with the help of the Computer (pH slat
Programming) The package also selected the best sets of the dependent and
independent variables where found to be In good flt, The best sets selected adjusted R', basing on the results were again tested uslng other tests Such as R 1
F-test and DW Statistic Regression 1s also done wkh lndlvldual variables* As
none of the variables was recommenQed for conslderatlon in the star
sets, the F-test and DW statistic have not incorporated in the analysls However,
the study found that some of the Independent var~ables have slgnlficant
relatlonsh~p with dependent variable and others have less s~gn~Rcant reiatlonslllp
explalnlng the dependent var~ables
The significance of the relationship between dependent and independent variable
Is tested uslng R2 Turning to the statistical slgnlficance of the estimated co-
efflc~ents, the slgn~ficance of co-efficient Of Independent variable 1s tested with F-
test The auto corelatlon between the Independent variable and Dependent
1s tested uslng Durbln Watson (DW) Test
T ~ I S study made an attempt a t finding out the case and effect relationship among
the monetary aggregates, economic growth and banklng variable Using multiple regression, aggregate deposits, gross credlt, gross domestic product, whole sale
prlce index and broad money and monetary instruments such as deposits Interest
rates, Cash Reserve Ratlo, Statutory Llqu~d~ty Ratlo and ~nterest rates on
advances as dependent variables as well as independent variables by trylng out
varlous permutations and combinations The bas~c oblective was to find out the
core variables among the monetary Instruments and monetary aggregates for
bringing about the desired level of growth In aggregate deposits, bank credit etc , The results o f the study have been tested, as already stated, with R2, adjusted
R2, F-test and DW S t a t ~ s t ~ c The results lnd~cated prevalence of auto correlation
whenever only two vanables were taken for finding out cause effect relationship
between them However, for a comblnatlon of variables, the study found that
auto correlation IS not prevalent in many of the cases

6.2 1 Aggregate Deposits
As Per the results, the dependent variable Aggregate Deposits is not being
Influenced by any s~ngle independent variable A comblnatlon of two or more
variables only was influencing the Aggregate Deposits, Obtalned the f ~ l l o ~ l n g
results of the regression analysis with Aggregate Deposits as Dependent variable
P Test and DW Statistic
Any one of the individual Independent variables taken for the study is not
influencing the Aggregate Deposits. The aggregate deposits are Influenced by all
the four independent variable as a group vlz, Broad Money, Whole sale Prlce
Index, GDP at Factor Cast and Deposit Rates, Uslng the RZ, which a t O 99889 IS
very very nearer to 1, tests the slgnlflcance. It shows that the enllre explanatory
variable accounted for 99.89 per cent of the varlatlons In ths Aggregate deposits 21 3
Turning to the statlstlcal s~gnlflcance of the estimated co-eff~c~ent, the s ~ y n ~ f i c a n c ~
of CO-effic~ent of independent variable ts tested with F Test The calculated F
(8790 13) IS far higher than the table value or F at 2 61 and hence the Ho null
hypothests ts rejected In favour of H1 This means that the regression co-eff~clent
1% s~gn~ f~can t The results are tested for any auto correlat~on between the
dependent and Independent variables uslng Durbin Watson (DW) Test Since the calculated DW at 1 928 a between du (1 29) and 4 -du (2 28) and hence
accepted the null hypothesis and that there IS no auto correlation between these
var~ables Finally after testing the results, It Is concluded that all the four
Independent var~ables as 8 group are slgnlflcantly Influencing the dependent
var~able
of all the four parameters, Broad Money and GDP at factor both put together Is
hav~ng scgntficant influence on the Aggregate Deposits, because the R' and
adjusted R2 are the are very close to one for two parameters put together than
any other cornb~natton and the standard error Is the lowest among all other
comb~nat~ons S~nce the calculated value of F (17976 7) Is far higher than the
table value of F (3 231, the null hypothesis Ho Is re~ected in favor of H l and
hence there IS stgn~ficant relatlon The auto co-relation Is tesled using Llie DW
Stat~stlc The calculated value of the DW Statlst~c (1 877) Is between the du and
4- du, accepted the null hypothesis and found that there Is no auto correlat~on
Of the other comb~natlons, Broad Money, GDP at factor and Deposlt Rates put
together 1s having slgnlflcant Influence on the Aggregate Deposits, because the R~
and adjusted R2 are the are very dose to one for these three parameters put
together than any other cornblnat~on and the standard error is lower Since the
calculated value o f F (11934 26) Is far hlgher than the table value of F (2 84), the
null hypothes~s Ho Is rejected In favor of H I and hence there Is slgniflcant
relatlon The auto correlation Is tested uslng the DW Statlstlc. The calculated
value of the DW Statlstlc (1 87668) Is between the du and 4- du, accepted the
null hypothesis and found that there Is no auto correlation,
Individually, the R2 and adlusted R2are maximum, Standard Error Is m l n l m ~ m for
broad money out of the four lndlvldual parameters followed by GDP and WPI
The Statist~cs also found that the changes that took place duflng the past 10
years, In the Interest rates do not have any slgnlflcant relatlonshlp on the
Aggregate Deposits movements as the R2 at 0 09985 and adjusted 17~ at 0,07616
and standard error a t 215392. The lnslgnlficant. relatlonshlp Is also proved with
calculated F value (4.2154) bolng only very marginally hlgher than the table
value (4.08) The result of the DW Statistic (0.360485) Is between 0 and dl 214
(1 44) provlng that there is a posltlve auto correlation between deposit rates anc
Aggregate Deposlh Finally concluded that the growth in Aggregate deposrts I!
interest rate ineiastlc and it has very Iim~tedlno influence in bririging aboul
changes in the deposit levels The changes in the Aggregate Deposlts also liave
an Impact on the movement of Deposlt Rates
The empirical resuits obtalned with the use of statistical methods can also be
collaborated with the help of theoret~cal understanding of the study and also
applying the commonsense economic arguments Deposits In a society are
determined by the state of economy In general and not by any parlicular
parameter All the Individual parameters may Influence very marginally I f Broad
Money Increases, it 1s natural that it 1s likely to effect deposlts, because the
economy 1s monetised and hence any changes in the flow of money to the society
will naturally increases the tendency to deposit more Similarly where there are
changes in lnflatlon, it 1s not possible that ail the money dlvetted to the deposlts
However, depend~ng on the level o f prices the quantum of Aggregate Deposits
may be affected L~kewise, i t is not necessary that the changes In deposlt rates
totally reflected i n the changes In aggregate deposits, Just because of Increase in
deposlt rate, people cannot be Induced to deposit thelr entlre money in deposlts
and the same way, because of fall in deposit rates, all bank depos~ts will not be
w~thdrawn Depos~tors' behav~or would depend upon other Interest rates and
market returns on various competrng instruments as well Similarly, the Impact of
growth In the GDP on depends will again depend upon the savings habit of the
sector which contributes most for the growth in GDP Hence, ail these
parameters are Interdependent and not a single monetary Instrument completely
affects changes in aggregate deposits
6.2.2. Gross Credit
As per the results, the dependent varlable Gross Credit Is also not being
influenced by any single independent variable. A comblnatton of two or more variables tends to ~nfluence the movement in credit Obtalned the following
results of the regression analysis wcth credit as Dependent varlable
Any one of the rndlvldual Independent vartables taken for the study is not
lnfluenclng the Gross Credit All the seven Independent varlables as a group vIz,
Broad Money, Whole Sale Price Index, GDP at Factor Cost, Deposlt Rates, CRR,
SLR and lending rates Influence the Gross Credlt Uslng the Rz, whtch 1s (0 gg ~ l ) ,
tests the slgnlf~cance and adjusted R2 (0 9952) Is slgn~ficantly greater rrom Zero
and nearer to 1 It shows that all the explanatory vartable accounted for 99 61
per cent of the varlatlons In Gross Credit Turning to the statlstlcal significance of
the estlrnated co-efficient, the significance of co-efficient of lndependent variable
IS tested wlth F Test The calculated F (1170 3599) 1s far hlgher than the table
value of F (2 34) and hence the i io null hypothesls Is rejected In favour of HI
~ h l s means that the regression co-efflclent IS significant The results are tested
for any auto correlatlon between the dependent and lndependent varlables using
Durbln Watson (DW) Test Slnce the calculated DW (1 1721) IS below dl (1 23)
reject null hypothesls and conclude that there IS auto correlatlo~l among these
variables When tested the other cornblnat~ons,/best sets, it Is statlsttcally proved
that there 1s auto correlatlon in most of these comblnatlons, as well i t means
that the reverse correlation IS possible among all the varlables Hence, we cannot
justlfy the tests, though they satisfy all other tests
It has stat~stlcally proved that the changes that took place durlng the past LO
years, In the Interest rates do not have any slgnlficant relatlonshlp on the Gross
Credlt movements The lnslgnlflcant relatlon IS also proved w i th adjusted
R2 belng 0.49380, whlch IS nearer t o zero and far below 1. Hence,
concluded tha t t h e growth in gross c red~ t is interest lnelastlc and It has
very I ~m l t ed /no Influence in brlnglng about changes i n the credlt levels.
The changes In the gross credlt also have an Impact on Llle movement of lnterest
Rates
Any one of the monetaw policy Instruments Is not able to Influence lndlvldually
the gross credlt All the four monetary pollcy Instruments effected during the
past ten years are influencing gross credlt but only as a comblnatlon The
slgnlflcance 1s tested by uslng the R2, which Is (0 9364751 slgnlflcantly greater
than Zero and nearer to One. The significance of co-efficient tested uslns F test
reveals that the calculated F value (128,9931) Is far hlgher than the Table vallie
and hence there 1s a slgnlflcant relatlonshlp between the dependent and independent varlaMes But the DW test reveals that there Is a posltlve auto
correlation between the dependent and Independent variables as the calculated
Value (0 520789) Is below the Table value dl (1 29)
The empirical results obtarned from the use of stat~stical methods can also bo
collaborated with the help of theoretlcai understandlng of the study and also
apply~ng the common sense economic arguments Credlt deployment IS
determined by many a parameters of the economy, and not by any single
parameter It is not necessary that the amount released to the public by way of
reductran i n CRR and SLR wrll not go to credit alone Practically, the reduction in
lending rates will not induce people to ava~l addltlonal credit from banks
Requirements of credit largely depend upon many other factors ralher than the
lendlng rates alone Llkewlse increase In wholesale prrce Index will not Increase
the credit i n the same ratlo Sometimes it may lead to fall In the credit also
People may not come forward to avail fresh loans just because the prices have
gone up Of all the four Monetary Policy instruments selected for study CRR is
Influencing the most on the gross credlt followed by SLR All the variables are
hav~ng the auto correlation deplctlng that there Is converse relationship among
the variables

TO amplify the existence of auto-corelation, regresslon equation was f~tted for
GDP as depedent variable and four Independent variable vlz., M3, WPI, Credlt and Deposlts as shown In the following Table The study found that all the four

I Regress~on Results for GDP with Broad Money, WPI, Gross Cred~t and Dcpos~ts
The significance is proved by adjusted R2 which Is at 0 9941 and the calculated F

Statrst~cs (0 478315) whlch IS below the table value DL (1 3) When the
stat~stical results are collaborated with Lheoret~cal understanding study and also
applylng the common sense economic arguments, it is true that GDP cannot be
lnfluenced by any in single independent variable and there will be an aulo-
correlat~on between the GDP and independent variables GDP Is be~ng dcc~ded by
all the other monetary aggregates and the all-monetary aggregates are be~ng

auto correlation between the broad money and the comblnatlon of CRR, SLR

(1 11) A comblnatlon of all the four dependent varlables registers p0~ilIVe auto
Co-relation Among the dependent varlables, only CRR Is havlng an adjusted R2
of 0 8913 which IS nearer to one and for all other var~ables it IS far below one,
lnd~catlng that no single Instrument is havlng slgn~ficant relation with broad

Durlng the past ten years of economlc reforms, many changes took place In the
Implementatlon of monetary policy Instruments All the monetaly policy changes
put together only Influenced the monetary aggregates af the economy None of
the monetary pol~cy instrument ind~vidualiy affected any one of tlie monetary
