ABSTRACT
The study attempts to explain the effects of inflows of private
foreign capital on some major macroeconomic variables in India using
quarterly data for the period 1993-99. The analyses of trends in private
foreign capital inflows and some other variables indicate instability.
Whereas net inflows of private foreign capital (FINV), foreign currency
assets, wholesale price index, money supply, real and nominal effective
exchange rates and exports follow an I(1) process, current account deficit
is the only series that follows I(0). Cointegration test confirms the
presence of long-run equilibrium relationships between a few pairs of
variables. But the dependence of each I(1) variable on FINV invalidates
such cointegration except in two cases: cointegration exists between
foreign currency assets and money supply and between nominal effective
exchange rate and exports, even after controlling for FINV. The Granger
Causality Test shows unidirectional causality from FINV to nominal
effective exchange rates- both trade-based and export-based-, which raises
concern about the RBI strategy in the foreign exchange market. Finally,
instability in the trend of foreign currency assets could be partially
explained by the instability in FINV with some lagged effect.

Introduction
Deregulation of private foreign investment in India started in 1993
in the form of partial liberalization of the capital account. Outflows of
capital by the Indian residents remained strictly controlled, whereas
inflows and outflows of capital by non-residents were partially
deregulated. These changes in policy framework not only led to a surge
in inflows of private foreign capital but also contributed to a significant
change in the form in which private capital was coming in. External
commercial borrowing which was the major source of private foreign
capital inflows during the eighties became less important during the
nineties. In the nineties, the predominant role of the portfolio investment
followed by the foreign direct investment (FDI) has been envisaged
1 .Estimates of portfolio investment through foreign institutional investors
(FIIs) and global depository receipts (GDRs) are $9 billion and $6 billion,
respectively, covering the period 1993-98 (Ahluwalia, 1999). Distinct
changes in the guidelines for portfolio investment and FDI vis-à-vis
external commercial borrowing during August and September of 1992
certainly encouraged the former categories (R.B.I, 1992). A look at some
of the items in the new guidelines will make it clear:
a) Use of external commercial borrowing would be prioritised to
the infrastructure and core sector export-oriented and importsubstitution
units and also medium-sized / small-scale units.
Infrastructure or core sector included power, oil exploration and
refining, telecommunication, fertilizer and transport.
5
b) External commercial loans could be raised only for meeting
foreign exchange cost of capital investment. Expenditure on
working capital could not be met by external commercial
borrowing. In addition, all external commercial borrowing should
have a minimum final maturity period of five years.
c) Priority will be given to those proposals for external commercial
borrowing which will be used for total export productions, which
will be self-liquidating i.e. the principal installments and interest
would be entirely serviced out of export-earning and for which
no security would be provided by a commercial bank/financial
institution in India.
d) Foreign institutional investors (FII) would be welcome to invest
in all the securities tradable in the primary and the secondary
markets. There will be no restriction on the volume of investment
by the FIIs. Moreover, there would be no lock-in period for the
proposed investments by the FIIs.
e) FIIs would be given tax-benefits. Concessional tax rate of 20 per
cent was proposed for the dividend and interest income. In
addition, a tax rate of 10 per cent on long-term capital gains (more
than one year) and 30 per cent on short-term capital gain were
proposed.
f) In connection with the FDI, the limit of 40 per cent of foreign
shareholdings imposed by the Foreign Exchange Regulation Act
(FERA) of 1973 on the Indian companies was raised to 51 per
cent in July 1991. The approval of foreign direct investment in
the priority industries where high technology was thought to be
needed was made automatic. Criteria for approval were also made
liberalised, in general.

The trend of private foreign capital depicted in Fig.1 shows
that portfolio investment exceeded the other two sources
between 1993-94 and 1996-97. However, the trend of
portfolio investment exhibits instability. On the other hand,
the flow of FDI appears to be increasing steadily over the
years. External commercial borrowing, the only major
source of private foreign capital prior to reform, reached
its all time trough in 1992-93 when it became negative.
Afterwards it followed an upward trend and it exceeded
the other two forms of private foreign capital during the
last two years i.e., 1997-98 and 1998-99.

A brief account of the net annual capital inflow in India since the
beginning of the 90's is presented in Table 1. It reveals that net inflow of
private foreign capital increased from Rs.605.2 crores (0.86% of GDP)
in 1992-93, the year just prior to the deregulation of private foreign
investment, to Rs.15187.5 crores (1.87% of GDP) in 1993-94. Easing of
restrictions on inflows of private foreign capital has also led to its
increasing share in gross domestic capital formation from 2.85% in 1990-
91 to 8.05% in 1993-94 and 9.3% in 1997-98. In terms of net capital
account, private inflows of foreign capital accounted for 53.58% and
79.01% in 1993-94 and 1998-99, respectively, whereas the same stood
at only 21.16% in 1985-86.
Some important changes may also be observed in the exchange
rate policy since July 1991. A significant downward adjustment in the
exchange rate took place in July 1991. On July 1, 1991, exchange rate of
rupee per unit of dollar was devalued from Rs.21.40 to Rs.23.25 and on
July 3 to Rs.26. Since March 1992, dual exchange rate system was
instituted. It was characterised by the coexistence of the official exchange
rate determined by the RBI and the market rate determined in the interbank
foreign exchange market. Since March 1993, exchange rate of rupee
was left to be determined by the market forces. In March 1993, the
exchange rate of rupee per unit of dollar became Rs.31.40 and it remained
steady for over two years at that level. But since the middle of September
1995 there were periodic speculative pressures on the exchange rate which
called for active intervention by the Reserve Bank of India in the foreign
exchange market. In the floating exchange rate regime, the predominant
objective of India's exchange rate policy was to maintain a stable REER
in order to prevent an erosion in the incentives available to exporters. To
meet this objective, it was announced that, "RBI stands ready to intervene
to maintain orderly market condition and to curb excessive speculation"
(G.O.I, 1995-96). The period after 1993, therefore, witnessed
8
interventions by the Reserve Bank of India several times to reduce the
excess volatility of the exchange rates.
Given these aspects of the reform programme, it is pertinent to
analyse the macroeconomic responses in the post-1993 period in India.
Importance of this issue can be traced back to different macroeconomic
consequences of liberalization of foreign capital in the countries of South-
East and East Asia vis-a-vis Latin America. Various studies observed
that in the post liberalization period in countries viz., Thailand, Indonesia,
Malaysia and Chile both investment and exports grew without any
substantial appreciation in real exchange rate. On the other hand,
Argentina, Mexico, Brazil, Columbia, Korea and Philippines experienced
a strong appreciation of their real exchange rate. In contrast to this
difference, it was further noted that in all these countries in both the
regions current account deficits and inflation increased (Khan and
Reinhart, 1995, World Bank, 1995 and Corbo and Hernandez, 1996). A
comparative picture of these two regions in terms of selected
macroeconomic indicators in the period of increasing inflow of foreign
capital is presented in Table 2.
The objective of this study is to observe and analyse the dynamics
of some selected macroeconomic indicators in relation to the inflows of
private foreign capital as a consequence of economic reforms in India.
The paper is organized as follows: section I discusses the trends in some
macroeconomic indicators and tries to explain them. Section II reports
the findings of some econometric analyses based on quarterly data from
1993.II to 1999.II. Finally we conclude in section III.
I. Trend behaviour of some Macroeconomic Indicators in relation to
Inflows of Private Foreign Capital in India with an Analytical Overview:
This section begins with the question: how might liberalization of
capital inflows affect macroeconomic aggregates in an open economy?
9
An economy seeking to attract foreign capital can experience different
macroeconomic consequences under different exchange rate regimes.
In what follows we consider the macroeconomic consequences under a
floating exchange rate regime and the discussion follows the arguments
available in the existing literature.
In a floating exchange rate regime, an increase in capital inflows
will lead to an appreciation of nominal exchange rate because of an excess
supply of foreign exchange. This appreciation under a floating exchange
rate regime generally leads to overshooting of nominal as well as real
exchange rate. This happens because as the financial market adjusts at a
faster rate than the goods market, surge of capital inflows may lead to
excessive appreciation of nominal and real exchange rates above their
equilibrium levels (Rangarajan, 1998). Overshooting of nominal
exchange rate will, in effect, ration the sale of foreign exchange for current
transactions. This will affect exports adversely because the consequence
will be similar to imposing an implicit tax on exports (Sachs, 1989).
Such a rationing, on the other hand, is likely to lead to the development
of a black market for foreign exchange. The rationing of foreign exchange
will lower the relative price of exports and bias production away from
exports. At the same time, imports may have increased due to the
appreciation of real exchange rate which, in turn, will have adverse effect
on the current account balance. In consequence expected depreciation
will generate pressure which will lead to excessive depreciation of
nominal exchange rate with some lag. This tendency of instability in
nominal exchange rate may result in a loss of confidence on the part of
the foreign institutional investors. Such adverse effects due to the
instability of the exchange rate may lead to a system of "managed float".
Under this system, the central bank intervenes in the foreign exchange
market to reduce the excess volatility in the exchange rate so that the
equilibrium is restored. There may be two types of central bank
intervention.
10
In the first type the central bank purchases foreign exchange against
the domestic currency. This will help control further appreciation of the
nominal exchange rate. On the other side, net foreign assets being one
component of reserve money, such intervention leads to the growth of
high-powered money and consequently increases the money supply in
the economy. With no change in the demand for money this will lead to
an increase in domestic absorption. Increased domestic absorption may
come through increased spending on either investment or consumption
or both. This increased spending will go to both the categories of goods
viz., tradables and nontradables. Increased expenditure on tradables will
increase the size of trade deficit. On the other hand, increased spending
on nontradables will increase the relative price of nontradables to
tradables. This, in effect, will have two consequences. One is the
reallocation of factors of production towards nontradable sector due to
the increase in its relative price. So it is interesting to observe that while
a large nontradable sector emerges, the consumer expenditure switches
from nontradables to tradables (Corbo and Henandez, 1996). The other
consequence is the effect on the real exchange rate. However, the direction
of change will depend on the rate of inflation relative to the initial
depreciation of the nominal exchange rate. If real exchange rate
appreciates there will be further deterioration of the current account
balance which will require further intervention by the central bank in
the form of buying foreign exchange. On the other hand, if real exchange
rate depreciates that may help improve the current account balance. But
depreciation of real exchange rate may also fail to produce all the desirable
results. Because too much depreciation may lead to reversal of capital
inflows simultaneously with the other effect. Hence, that will require
further intervention by the central bank but in the form of selling foreign
exchange so that nominal exchange rate appreciates to some extent. Such
intervention by the central bank will continue till a new "equilibrium" is
reached for the exchange rate.
11
The second type of central bank intervention is known as "sterilized
intervention". In this process the central bank buys foreign exchange in
exchange of government securities. It helps to curb the growth of money
supply in the economy and hence there will be no increase in domestic
absorption. In consequence, there will be no increase in the current
account deficit too. But it creates an upward pressure on the domestic
interest rate and hence increase fiscal deficits (Joshi and Little, 1994).
Further an increase in the interest rate may attract more foreign capital
which would aggravate the problem of management of capital inflows.
Another limitation of sterilized intervention is that the central bank has
to incur some costs while using this instrument. The associated cost will
be equivalent to the difference between the interest to be paid by the
central bank on government securities and the return enjoyed by the
central bank on holding foreign reserves. This will happen because
sterilized intervention by the central bank in the context of liberalization
of private foreign capital will lead to an increase in interest rate for
government securities
2 .In the light of the above discussion, let us now analyse the trend
behaviour of some macroeconomic indicators in India. For the trend

analysis we have chosen the period 1990-91 to 1998-99 which will help
to form a comparative picture of the post-reform period and the period
just prior to the reform.
The foreign exchange reserve in India has increased considerably
since the initiation of economic reforms (Fig.2). The reserve has gone
up by US $27286 million between 1990-91 and 1998-99. Although it
was steadily increasing since 1991-92, the volume was not quite high
during the first three years. The reserve had started to peak up since
1993-94. It happened mainly because of intervention by RBI against the
surge of capital inflows. Initially RBI followed "sterilized intervention".
But since the treasury bill market was not properly developed this process
could not be continued for a longer time. During the later period
intervention by RBI was mostly through purchase of foreign currency
for domestic currency (Reddy, 1999, Rangarajan, 1998). Consequent
upon the increase in foreign currency assets due to RBI intervention in
the foreign exchange market, there was a rapid growth in money supply
in the post-reform period (Fig.3 and Table 4).
Fig. 3. Money Supply (M3)

Let us now consider if the increase in money supply led to an
increased domestic spending in the post-1993 period. Figure 4 shows
that investment as a percentage of GDP follows an upward trend since
1993-94 and continued till 1997-98 when the level of investment was
much higher than that during the two years prior to 1993-94. The same
figure also reveals one of the important features in the post-reform period,
that is, a sharp increase in the private sector investment. However, this
achievement should not be attributed entirely to the liberalization of
capital inflows because some other reform measures have also contributed
towards this end. These reform measures include relaxation of restrictions
on industrial licensing and reduction of tariff on imports of capital goods
(Athukorala and Sen, 1995). Consumption expenditure as a percentage
of GDP, on the other hand, does not exhibit any upward rising trend in
general, but sharp increases are observed during the last two years (Fig.5).
Total consumption expenditure, combining both private and public,

increased sharply in 1997-98 to 75.8% of GDP from 67.9% of GDP in
1996-97. Interestingly enough, private consumption expenditure steadily
declined after economic reform until 1996-97 and then increased during
the last two years (Table 3). While disaggregated data on consumption
expenditure are not available, data on different categories of imports
suggest that the rising expenditure on consumption was not heavily driven
by manufactured imports (Table 3). In contrast to this it may be noted
that the Latin American countries experienced a consumption boom
mainly driven by imports of consumer durables in the post-liberalization
period. The period since 1993-94 also witnessed an increase in real GDP.
Although the growth in real GDP has reached its highest value in 1996-
97, it was varying between 7.2% and 7.5% during the period 1994-95 to
1996-97 (Table 3). However, it started to decline sharply since 1997-98.

Trend behaviour of savings as a percentage of GDP was almost similar
to that in investment except the fact that the gap between savings and
investment was widening since 1993-94 (Fig.4).
Trend behaviour of inflation is reported in Fig.6. Increased money
supply led to a rise in the inflationary pressure during the initial years
after reform viz. between 1990-91 and 1992-93. Due to the policy of
targetting inflation stabilization, however, it had been possible to keep
inflation below double digit level since 1993-94 excepting the year 1994-
95. Nominal effective exchange rate (NEER) and real effective exchange
rate (REER), (both export-based and trade-based) reveal a declining trend
since 1990-91 and it appears that the nominal effective exchange rate
depreciated at a faster rate than the real effective exchange rate (Fig.7).
Prior to 1993-94, it had been made possible by the devaluation of nominal
exchange rate of the rupee twice in July 1991 and by containing inflation
within a stable limit. Even after the liberalization of capital inflows since
1993-94, nominal effective exchange rate did not appreciate mainly
because of the direct intervention by the Reserve Bank of India in the
Fig. 6. Inflation

foreign exchange market, as discussed earlier. The real effective exchange
rate (REER), however, appreciated between 1993-94 and 1994-95
because of a rise in inflation in India in that period at a faster rate
compared to her trading partners. On the whole, movement of both the

indices of exchange rate in the downward direction during the entire
period 1990-91 to 1998-99 indicates that the policy of targetting REER
by adjusting NEER seems to have been partly successful during the 1990s.
Depreciation of REER seems to have improved the external trade
competitiveness because, it appears from Fig.8 that exports follow an
increasing trend since 1990-91. Imports as a percentage of GDP, on the
other hand, declined initially to 7.7% in 1991-92 from 8.1% in 1990-91
and started to increase thereafter. In relative terms, imports increased at
a faster rate than exports particularly in two years viz., from 1991-92 to
1992-93 and from 1994-95 to 1995-96. Hence, there were sharp increases
in the current account deficits during these two periods. If we look at
Fig.4 it is visible that, during these two periods there were sharp increases
in investment relative to savings too. Despite some fluctuations, the
overall trend in the current account deficit appears to be declining (Fig.8).
Thus, unlike some of the Latin American countries, the surge in the
inflows of capital, did not result in an increase in the current account
deficits in India.
II. Findings and Analysis
This section empirically analyses the effects of inflows of private
foreign capital on some of the major macroeconomic variables in India
using the quarterly data for the period 1993.II-1999.II. We try to
understand if the observed fluctuations in the time-series of some
macroeconomic variables viz., foreign currency assets
3 , wholesale priceindex, money supply, real and nominal effective exchange rates, exports
and current account deficit, as reported in the earlier section, can be
explained in relation to the fluctuations in the time series of inflows of
private foreign capital. Research done over the past decades shows that
before indulging in any econometric modelling using time-series data,
one should be concerned about the problem of non-stationarity or unit
18
root problem. Results from a regression exercise involving nonstationary
data is observed to be spurious (Granger and Newbold, 1974 and Granger,
1981). Therefore, the following empirical analysis is carried out in the
light of the recent developments in the time-series analysis.
In the first stage, stationarity of the series on each variable is
examined using both the Dickey-Fuller (DF) test and Augmented Dickey-
Fuller (ADF) test. The DF test is based on the following regression:
Y
t = C + át + äYt-1 + åt…………….(1)where C is a constant and t is the trend component.
The null hypothesis of unit root in Y
t or nonstationarity of Yt isrejected if
ä is negative and statistically significant. If C and á failedto be statistically significant we run the above regression dropping the
constant and trend. Critical values for
ä in such a situation are noted tobe different from the one in equation (1) above.
For ADF test we include the lagged difference terms as regressors
in the above equation i.e.
k
Y
t = C + át + äYt-1 + Ó âi Yt-i + åt ………………(2)i =i
Following Enders (1995), to select the number of lagged
differenced terms we started with a relatively long lag length namely 15
in this case. Since the t -value for
â at lag 15 was statistically insignificantwe estimated equation (2) with 14 lagged differenced terms and again
we tested for statistical significance of the t-value corresponding to
â atlag 14. This process is repeated until a lag is found which is statistically
significant. The number of lags chosen is reported below each equation
under ADF test.
19
The results are reported in Table 5. All the variables are transformed
to natural logarithm, except CAD which includes negative values. DF
test shows, for none of the variables at the level, the hypothesis of
nonstationarity can be rejected at 1% level of significance. However, it
is rejected at 5% level only for some of the variables viz., FINV, FNCA,
WPI, and CAD. But the DF test at the first difference of the series shows
that stationarity condition is uniformly supported at the 1% level of
significance by all the series except CAD. On the other hand, it follows
from the ADF test that none of the series, except CAD and NEERX are
stationary at the level. However, all the series except REERT, EXP and
CAD appear to be stationary at their first difference following ADF test.
Therefore, from these results it follows that all the series have unit roots
except CAD which is only stationary at the level.
The fact that all the series except CAD are I(1), or nonstationary
at the level, is important. What follows from the nonstationarity or the
presence of unit root in a time-series variable is that the time-path of the
variable is diverging from its equilibrium. The idea of convergence
towards equilibrium represents "stability" in the context of difference
equation, where lies the conceptual origin of the term "unit root". Thus
the presence of unit root indicates instability. However, if a set of
nonstationary variables is observed to be cointegrated then it follows
that the variables will come back to equilibrium in the long-run, even if
they drift away from equilibrium in the short-run. Hence it is necessary
to examine if there exists any cointegrating relationship between the set
of variables observed to have I(1) process before drawing any inference
regarding their instability.
Before going to the second stage, some diagnostic checking was
carried out to verify if the number of differenced lags was selected for
ADF test appropriately. The residual analysis for ADF regressions at the
20
first difference of each variable is reported in Table 6. The appropriate
number of lags in ADF regression should not reveal any significant
autocorrelation among the residuals or heteroscedasticity. Presence of
autocorrelation can be verified using Ljung-Box Q-statistic and Box-
Pierce Q-statistic whereas the presence of heteroscedasticity can be
verified using the ARCH test. Varying the number of lags in the residuals,
considering for example 2, 4 and 6 we observe that residuals exhibit no
autocorrelation for all the I(1) series except REERT and REERX. On
the other hand, ARCH test supports the assumption of homoscedasticity
for residuals of all the I(1) series
4 .In the second stage, tests for cointegration are applied to examine
if there exists any long-run equilibrium relationship between any pair of
I(1) variables. A number of series are said to be cointegrated if they are
nonstationary at the level and have same order of integration but there is
at least a linear combination of these variables which is stationary. We
have carried out cointegration test for each pair of variables having I(1)
series by making use of the methodology suggested by Engle and Granger
(1987). The results are reported in Table 7. We find, following either the
DF or ADF test results, that all the I(1) variables individually have
cointegrating relationship with FINV. In addition, cointegration is
observed between the following pairs of variables: FNCA and M3, M3
and WPI, WPI and REERX, WPI and REERT, REERX and EXP, REERT
and EXP, NEERX and EXP, NEERT and EXP. The results of
cointegration test in the latter sequence of relations suggest that the longrun
equilibrium relationship is restored between the following pairs of
variables viz, foreign currency assets and money supply, money supply
and inflation, inflation and real exchange rate, real exchange rate and
exports during the period 1993-99. These long-run relationships, based
on the observed data, reflect that the covariate fluctuations for the
variables in each pair are correlated over time. These relationships,
21
however, need to be analysed carefully, because such cointegration
relationship between variables in each pair breaks down in most of the
cases when we include FINV as a third variable. The results of the test
of cointegration, reported in Table 8, reveal that we fail to reject the null
hypothesis of no cointegration in all the cases but with two exceptions.
These two exceptional cases are (M3, FINV, FNCA) and (NEERX, FINV,
EXP) where these two sets are observed to be cointegrated following
the DF and ADF tests, respectively. The above results suggest that if we
control for the variable FINV, no long-run equilibrium relationship holds
between the variables for most of the above mentioned pairs of variables.
These findings are indicative of the fact that the increased inflows of
foreign capital in India since 1993 might account for the disturbances in
the equilibrium relationship between a number of macroeconomic
variables with a few exceptions. Exceptions, which follow from our study,
are between foreign currency assets and money supply and between
nominal effective exchange rate and exports.
The test of cointegration ignores the effect of the past values of
one variable on the current value of the other variable. So, finally, we
tried the Granger causality test to examine such possibilities. Since the
reliability of results of the Granger causality test depends on whether
the variables are stationary or not, we applied this test on the first
difference of the log transformed series which are reported to be
stationary. It is well-known that Granger causality test is sensitive to the
choice of lag length. To avoid this problem, as noted in Enders (1995)
we have applied Akaike information criterion to choose the optimum
lag length
5 .The results are reported in Table 9. Major observations are
discussed here. The most important observation is that FINV Granger
causes NEERT and NEERX. This has relevance for the exchange rate
22
policy. What it implies is that the past information on FINV improves
the predictability of NEERT and NEERX. As discussed earlier, RBI
intervened in the foreign exchange market with certain objectives since
1993, one of which was to "curb excessive speculation". The above
finding, however, challenges this objective. The direction of Granger
causality from FINV to NEERX and NEERT indicates that even if RBI
does not disclose its strategy of intervention a priori, it is possible to
speculate about the nominal exchange rate given the past information
on the inflows of private foreign capital. We further observe that FINV
Granger causes FNCA. This result suggests that, in the post reform period,
instability in the trend behaviour of foreign currency assets can be
explained partly by the instability in the trend behaviour of the inflows
of private foreign capital with some lagged effect. However, no causality
is observed between FINV and other variables having I(1) process.
III. Conclusion
A large volume of recent literature, while analysing the experiences
of Asian and Latin American countries, reveals that financial liberalization
led to severe macro-economic instability in several of those countries
and no unique pattern emerged in this respect. This study, therefore,
made a modest attempt to analyse the dynamics of some major
macroeconomic variables during the post-reform period in India. The
main focus of this study lies in analysing the behaviour of some selected
macro-economic indicators in relation to the surge in inflows of private
foreign capital in India since 1993, the year in which several major reform
programmes were initiated. A review of the analytical literature shows
that macroeconomic consequences of financial liberalization are the
results of the combined effect of monetary, fiscal as well as trade and
exchange rate policies followed by the government of a country. So,
there is no straightforward way of predicting the resulting macroeconomic
effects of financial liberalization in any country.
23
Major observations from the trend analysis, covering the period
1990-91 to 1998-99, are as follows: (a) Inflows of private foreign capital,
measured as the aggregates of foreign direct investment, portfolio
investment and external commercial borrowing, increased sharply since
1993-94. Although the volume of portfolio investment increased
enormously its trend exhibits instability. Flow of foreign direct
investment, on the other hand, increased steadily after the reforms. (b)
Foreign exchange reserve increased by a considerable amount which
indicates intervention of RBI against the surge of capital inflows.
Consequently, a rapid growth was observed in money supply. (c)
Investment as a percentage of GDP, private investment in particular,
followed an upward rising trend. Total consumption expenditure as a
percentage of GDP, on the other hand, did not reveal any clear pattern.
Private consumption expenditure, however, steadily declined. Real GDP
followed an increasing trend. (d) Inflationary pressure was mostly under
control except in the three years prior to 1993-94. Except in the two
years 1993-94 and 1994-95, real effective exchange rate (both exportbased
and trade-based) declined sharply. It had been made possible by
the downward adjustment of nominal effective exchange rate as well as
containment of inflation within a stable limit. (e) Unlike the Latin
American countries, current account deficits as a percentage of GDP did
not increase sharply excepting the two years 1992-93 and 1994-95.
Some econometric analyses based on quarterly data for the period
1993.II-1999.II reveal a number of interesting observations. It is found
that each of the following series viz., inflows of private foreign capital,
foreign currency assets, wholesale price index, money supply, real and
nominal effective exchange rates and exports follows an I(1) process
whereas the only series which follows an I(0) process is the current
account deficit. I(1) process indicates instability in the trend behaviour
of the variable under consideration. Tests for cointegration are applied
24
to examine if there exists any long-run equilibrium relationship between
any pair of I(1) variables. All the I(1) variables individually have
cointegrating relationship with FINV. In addition, cointegration is
observed between the following pairs of variables: FNCA and M3, M3
and WPI, WPI and REERX, WPI and REERT, REERX and EXP, REERT
and EXP, NEERX and EXP, NEERT and EXP. Further tests shows that
such cointegration relationship between variables in each pair breaks
down in most of the cases when we include FINV as a third variable.
The two exceptional cases where the cointegration relationship exists
even after controlling for FINV are foreign currency assets and money
supply and between nominal effective exchange rate and exports. Results
of the cointegration test are indicative of the fact that the increased inflows
of private foreign capital in India since 1993 might account for the
disturbances in the equilibrium relationship between a number of
macroeconomic variables with a few exceptions.
Finally, the Granger causality test is applied to examine if there is
any lagged effect of inflows of private foreign capital on the
macroeconomic variables under consideration. The direction of causality
from FINV to NEERX and NEERT has some relevance for the exchange
rate policy. It raises concern about the strategy of RBI intervention in
the foreign exchange market, one objective of which is to curb
speculation. Another finding from the causality test, that FINV Granger
causes FNCA, suggests that in the post reform period, instability in the
trend behaviour of foreign currency assets can be explained partly by
the instability in the trend behaviour of the inflows of private foreign
capital with some lagged effect.
25
Notes:
1. Private foreign capital may be classified into three categories viz., (a)
foreign direct investment (b) portfolio investment and (c) external
commercial borrowing. With the opening of the Indian stock market to
foreign institutional investors (FII) and allowing the private corporate
sector to issue global depository receipts (GDRs) in 1993, portfolio
investment entered as a new category into the private foreign investment
in India in the nineties. Nevertheless, liberalization of foreign capital in
the form of foreign direct investment can be traced back to the beginning
of 1980's with a distinct change in the country's foreign investment policy
(RBI, 1991). In 1980 a scheme was introduced to attract investments
from the oil-exporting developing countries. Under this scheme investors
from the Gulf region were allowed to invest in the equity capital of Indian
companies upto 40% of the total paid-up capital. Liberalised investment
facilities to non-resident Indians was another important policy decisions
taken during early 1980's.
2. Prior to financial liberalization, interest rate on government securities
may be deliberately kept at a low level. But financial liberalization will
lead to a market-determined interest rate on government securities which
will be definitely higher than the earlier level.
3. Since foreign currency assets form the major component of foreign
exchange reserve that influence money supply in an open economy, we
have included foreign currency assets in our empirical analysis.
4. Absence of serial autocorrelation and heteroscedasticity in the estimated
residuals confirm that the power of ADF test is reliable. Absence of
heteoscedasticity is evident from the ARCH test results reported in Table
7. It justifies that Phillips-Perron test is not required under this
circumstance.
5. Some empirical studies which have applied this criterion include Samanta
and Mitra(1993),Masih and Masih(1994), Ghosh(1995).

1.
GDP at current price for the year 1997-98 is converted to 1980-81 prices. Basic data source is RBI (1999), Handbook of Statistics on Indian
Economy. Figures for 1988-99 in this column is obtained from C.S.O (1999), National Accounts Statistics.
2.
GDCF at current price is similarly computed and the source till 1997-98 is R.B.I (1999), as stated above. The same figure for 1998-99 is
computed on the basis that it is 23.4% of GDP, which information is collected from CMIE (June 2000), Monthly Review of the Indian
Economy.

model. With 24 observations, T/4 is equal to 6. Significance levels are in parentheses.
(ii)
F-statistic and nR
2provide ARCH test for the heteroscedasticity in the estimated residuals. ARCH test is
based on the specification that the squared residuals from the estimated model is related to the lagged
squared residuals. Each statistic is estimated using three different lags viz., 2, 4 and 6. nR
2 statistic has a chisquaredistribution with degrees of freedom equal to the number of lagged squared residuals and here n
refers to the number of observations.
(iii)
* indicates significant at 1% level and ** indicates significant at 5% level.

Notes:
(i) Reported results are based on regressions including a constant
and a trend .
(ii) Reported results for ADF test correspond to 11 lags, the highest
possible number of lags that can be chosen for the given number
of observations. ADF test is also tried with other lags going
down to the least possible number of lags. The null hypothesis
of no cointegration is rejected in none of these case.
(iii) ** indicates significant at 5% level.
