Abstract
Economic growth in a country is entirely driven by the accumulation of technologically progressed
capital machinery and input factors along with the potential role of finance (private sector credit) to
assist the accumulation of capital. Following the hypothesis, the Bangladesh economy registered
annual growth rate more than 6 percent during the last decade. Industrial output mostly contributed
to GDP growth through the process of exports of manufacturing products. In Bangladesh, the
industry sector contributed around 30 percent in GDP and recorded over 8 percent growth in
FY2014. However, the country has a comparative disadvantage in producing capital machinery and
industrial raw materials; the import of capital goods and industrial raw materials fill this gap. The
economy covered around 23 percent by import, while imported capital machinery and industrial raw
materials occupied almost half of the total import. In this paper, we focus on the question whether
capital financing promotes industrial output growth as well as in economic growth. Based on the
available empirical evidences using the cointegration and vector error correction model we find
significant result that in the long-run there remains a positive relationship between capital financing
and industrial output growth in Bangladesh. The evidence suggests further export promotion and
imports of capital goods not only for Bangladesh, but also for other emerging economies that seeking
foster growth through economic openness.

1. Introduction
While, the global financial crisis of 2008 adversely affected almost all the economies of both
developed and developing countries; Bangladesh, one of the South Asian developing
economy recorded more than 6 percent GDP growth per annum since 2004 along with strong
macroeconomic fundamental. The accomplishment has drawn attention in the global
economy and has become a model in developing countries. Since early nineteen-eighties, the
gradual shifting of its polices from anti-export bias to export promotion by providing various
export incentives, by deregulating the import process through reducing tariff and non-tariff
barriers, and by implementing investment friendly fiscal and monetary policies have
significantly contributed in the remarkable economic growth of the country. Subsequently,
the industry sector has been expanded; share of industrial output in GDP became almost
double in FY20141 from 15 percent in early eighties. The annual growth rate of industrial
output also increased to 8.4 percent in FY2014 from the around 2 percent in early eighties.
Since the independence in 1971, Bangladesh has a comparative disadvantage in producing
capital machinery and industrial raw materials. The import of capital machinery and
industrial raw materials from technologically advanced countries maintained this gap. The
under policy measures during early eighties promoted the import of capital machinery and
industrial raw materials for domestic manufacturing industries that played a key role in the
process of industrialization of the country. The economy accounted around 23 percent by
imports and total import payments stood at USD 40.69 billion in FY2014; while, the imports
of capital machinery and industrial raw materials occupied almost half of total import. In
early eighties, the share of total import in GDP was around 14 percent and the imports of
capital machinery and industrial raw materials contributed around 13 percent in aggregate
import. Thus the import of capital goods stimulated the productivity of domestic industries
that increased industrial output that lead the economic growthHowever, most of economic
literatures in developing economies in Asia- like South Korea, Malaysia, Thailand,
Singapore, Taiwan find that the import of capital goods and private investment escalated
countries’ industrialization process that lead to attain a higher and sustainable growth of
industrial output (Awokuse, 2007; H. Rana, 2000). In Bangladesh economic literature,
although research on exports, remittance inflows, economic growth and poverty is numerous;
1 FY refers Fiscal Year that starts July and ends June.
-:4:-
to the best of our knowledge there are little paralleled studies particularly on the area of
capital financing and economic growth in Bangladesh..
On this context, the main objective of our study is to search whether there have any long-run
relationship between industrial output growth and capital financing; analyzing the
contribution of capital financing to the growth of industrial output of Bangladesh by applying
quantitative econometric techniques. We define capital financing in terms of imports of
capital machinery and industrial raw materials, and private sector credit. These factors are
commonly used in the industry sector aiming to foster countries’ economic growth through
industrialization.
In this paper, we develop a model by taking variables- industrial output, imports of capital
goods, private sector credit and real interest rate for the period FY1980 - FY2014. The
Johansen cointegration technique and vector error correction (VEC) model along with
supportive econometric test criterions are applied in this study. We also present a synthesis of
the cointegration and innovation accounting to unveil the relationship among the variables
that used in the model for short-run and long-run dynamics. We find evidence that there
exists a positive long-run cointegration relationship between the variables of capital financing
and industrial output growth. The finding suggests that, like many other developing and
emerging economies in Bangladesh, imports of capital goods promote industrial output
growth that support the economy to achieve a higher and sustainable GDP growth in the
long-run.
The rest of the paper comprises as, Section 2 contains the literature review; Section 3
provides the description of the variables considered and the methodology. Estimating results
of the cointegration and error correction model are discussed in Section 4 and conclusion is
drawn in Section 5.
2. Literature Review
Economists have been centered in the growth hypothesis across countries and most of the
studies find that factors such as exports, imports, remittances, investment and economic
openness lead economic growth for instance. They have analyzed these factors based on
different theoretical frameworks, from the neo-classical growth model to recent endogenous
growth model. Since, the main objective of our study is to examine the existence of long-run
-:5:-
positive relationship between capital financing and industrial output growth in Bangladesh,
we seek literatures those are mostly relevant in this regard as follows.
Both approaches as mentioned above, import-led growth consider technological progress
through availability of capital machinery and input materials, human capital as well as
private investment in both developed and developing countries. As, developing countries
have comparative disadvantage in producing capital goods, literatures support that imports of
capital goods promote industrialization in these countries. Evidences supporting import-led
growth can be found in the cross country study of Thangavelu and Rajaguru (2004) for India,
Indonesia, Malaysia, Philippines, Singapore and Taiwan. Similar findings are also found in
the literature of Awokuse (2007) for Poland and in Awokuse (2008) for some South
American countries.
On Indian economy, H. Rana (2000) finds that imported technology and capital goods that
use in domestic manufacturing industry has a positive impact on country’s economic growth.
The study also examines that newly established domestic industries those produce capital
goods contribute to the increase of productivity of manufacturing industries; where the
productivity of domestically produced capital goods itself seems to stem from imported
technology. For Turkish economy Uğur, A. (2008) finds a casual relationship between output
growth and total import. The author also discovers mixed causality relationship between
various categories of imports (imports of investment goods, raw materials, consumption
goods and others) and GDP growth. Accumulative capital and the relative proportion of
imported capital goods over domestically produced capital goods that use in domestic
industries directly promote the Chinese per capita income also GDP growth (Herrerias and
Orts, 2011). They argue that imported capital goods encourage Chinese GDP for long-run in
the process of trade openness.
In case of Bangladesh, Dawson (2006) finds imports negatively cause GDP and exports cause
GDP to grow fast. He uses annual data for the period 1973-2003. Pre and post reforms period
were considered that might be provide such result. Hossain et al. (2009) using annual data for
the period 1973-2009 also could not find any relationship between imports and economic
growth. They find that in long-run exports impact economic growth positively. They also find
that exports significantly promote imports in the long-run as well in the short-run but not vice
versa. Using Engel-Granger casualty test Mamun and Nath (2005) find unidirectional
casualty from exports to GDP growth over the period 1976Q1 – 2003Q4. In this study
-:6:-
industrial production index is used but could not find any impact of that on GDP. On the
other hand, Sultan P. (2008) evidences that there exists a cointegration long-run relationship
between GDP and industrial value added; the Granger casualty test supports that GDP
growth rate causes industrial value added but not vice-versa. , Hossain (1995) estimates a
manufacturing production function by applying OLS for the period 1974:Q1-1985:Q4 where
and find a positive impact on manufacturing output of real expenditure which is proxy of
imported capital goods and private sector credit. .
However we find that there is no such a study that focuses particularly the impact of capital
financing on industrial output growth in Bangladesh. Our study attempts to overcome this
shortcomings clearly focusing on capital financing (imports of capital goods and private
sector credit) and industrial output growth in Bangladesh.
3. Model, Methodology and Data
3.1 The Model Specification
Economic theory asserts that acceleration of industrial production depends on the availability
of capital financing for the imports of capital machinery and industrial raw materials in both
developed and developing economies. Like many other developing countries, Bangladesh
economy requires capital machinery and input materials as the country has a comparative
disadvantage in producing such goods. The factors strongly contribute to the growth of GDP.
Based on this hypothesis, the main objective of our study is whether the capital financing and
industrial output are positively associated or not and to analyse the impact of the import of
capital goods and private sector credit as exogenous variables on industrial output growth in
Bangladesh. In this case, for simplicity we develop a four-variable model that stated as:
Y_INDt = f (IMP_CGt, PRCt, IRt) (1)
In difference form
∆Y_INDt = f (∆ IMP_CGt, ∆ PRCt, ∆ IRt) (2)
Where, Y_IND is industrial output, IMP_CG denotes imports of capital goods (including
imports of capital machinery and industrial raw materials), PRC is private sector credit from
banks, IR denotes interest rates, t is year and ∆ represents first difference of the variable.
-:7:-
Assuming that imports of capital goods and private sector credit are positively associated
with industrial output; on the other hand, interest rate impacts industrial output negatively.
Following the equations 1 and 2, we develop the error correction equation that to be
estimated as follows,
∆ (LnY_INDt) = α + Σ β1∆ (LnIMP_CGt) + Σ β2∆ (LnPRCt) + Σ β3∆ IRt + εt (3)
Where, t represents year, ∆ is first difference calculation, Ln is natural logarithm, and ε is
residuals of the sample. α is constant term of the equation and βi (i = 1, 2 and 3) denotes
estimated parameters where β1, β2 > 0 and β3 < 0 (i, e, the signs of the coefficients of β1, β2
are positive and negative for β3.
3.2 Methodology
Cointegration technique is adopted in this paper to examine whether there remains the long-
run relationship among the variables of industrial output, imports of capital goods, private
sector credit and real interest rate in the model of equation 3. We also estimate the equation
by using vector error correction (VEC) model and test the adjustment dynamics for any
disequilibrium position of any shock in the economy. The whole process is developed by
three steps.
The first, testing unit roots process of the series to identify the order of integration of the
variables considering in this study. In econometric analysis most of the macroeconomic
variables are characterized by unit-root processes i.e., non-stationary (Nelson and Plosser
1982) for time series data. In general, unit roots precede cointegration test; otherwise,
regression of non stationary variables may leads to spurious results. The Phillips-Perron (PP)
test and the Augmented Dickey-Fuller (ADF) test are the most commonly used to check the
stationary of the series. However, Phillips and Perron (1988) propose a modification of the
ADF test and have developed a comprehensive theory of unit roots. The PP test has
established a t-statistics on the unit root coefficient in the ADF regression which corrected for
autocorrelation and heteroskedasticity. Maddala and Kim (1998) argue that the DF test does
not have serious size distortions, but less influential than the PP test. Choi and Chung (1995)
also argue that for low frequency data, the PP test emerges to be more persuasive than the
-:8:-
ADF test. Hence, we apply the PP methodologies to test the unit roots of the variables and
whether the series are I(0) or I(1).
The second, checking the long-run relationship among the variables of the model as stated in
equation 3. If the variables are found to be I(1), i.e., series are stationary at first difference,
cointegration is to be pursued as per the Johansen approach following the literatures of
Johansen (1988), Johansen and Juselius (1990), and Juselius (2007). In this study, the number
of the cointegration relation must be less than four as there are four variables in the model.
We apply both the trace and maximum eigenvalue tests to check the existence of long-term
cointegration relationship of the variables in the model.
Finally, we analyse the long-run relationship and error correction mechanism using VEC
techniques. Moreover, in innovation accounting process we analyze the impulse response
functions and variance decompositions of the variables in the system to unveil the dynamic
relationship among the variables. The model is also being tested with the sequence of miss-
specification tests without showing any autocorrelation or normality problems.
3.3 The Data Set
In this study, we employ annual data for the period FY1980-FY2014. The period is taken that
started in FY1980 for that first, the period FY71-76 was under socialist planning, post-war
anomalies, militant coups and external shock. The first decade almost passed by
reconstructing the demolished infrastructures such as roads, highways, bridges, buildings,
houses and power stations those were badly damaged or demolished during the Liberation
War in 1971. In addition, the famine of 1974 almost crippled the economy, and causing
starvation, diseases and deaths. The global oil shock of 1974 reinforced the supply shock of
the famine; the country’s socio-economic condition became worse. In 1975, the economy was
also affected by the bloody military coup. Thus, the period FY1972-FY1975, could not be
entirely attributed in economic activities by the policy measures those were associated with
high level of nationalization process under socialist planning.
Secondly, major policy changes related to the transition of the economy from nationalization
to privatization process were carried out after 1975. Since 1976, economic policies shifted to
private sector-led export promotion industrialization strategy from public sector-led and
import-substituting strategies through the declaration of the Industrial Investment Schedule in
-:9:-
1976, the withdrawal of private investment ceiling in 1978, and the promulgation of the
Foreign Investment Act in 1980. Aiming to improve competitiveness, enhancing economic
efficiency and promoting export-led growth major significant policy reforms such as
dismantling state enterprises’ interventions, increasing participation of private sector,
launching peg exchange rate with a basket of currencies by dropping single currency fixed
exchange rate (against Pound Starling), reducing tariff and non-tariff barriers, etc. were
undertaken during the period FY1976-FY1980. Due to these widespread turbulences and
transition of the economy as discussed above, the Bangladesh’s economic growth as well as
other macroeconomic indicators was highly volatile during the period FY1972-FY1979
(Appendix Figure 1). Hence, by excluding the period FY1972-FY1979, we consider sample
period that begins in FY1980 to avoid any spurious results.
Taking into account the previous discussion, our dataset consists of industrial output
(Y_IND), imports of capital goods (IMP_CG)2, private sector credit (PRC) and interest rate
(IR). All variables are in real terms3. Natural logarithm form is used here for all variables
except interest rate for convenience to get stationary more easily, and is helpful to eliminate
the heteroskedasticity problem of time series data that is very common practice in
econometrics. However, the characteristics of time series and the relationship among the
variables would not be changed. The series of imports of capital goods and private sector
credit in value (million BDT) and nominal interest rate (in percentage) have been collected
from Bangladesh Bank (BB), and industrial output (value in million BDT) and consumer
price index (CPI) have been collected from Bangladesh Bureau of Statistics (BBS). The
sources are the authorities of the respective series; there is no doubt about the originality of
the data.
4. Estimation Results
4.1. Unit roots tests
In this study, the variables that we have used as we see in Panel A of Figure 2 in Appendix I,
are most likely to have unit roots in levels. To test unit roots in the variables of the model we
apply the PP methodologies. Accordingly, the results present in Table 1, show that series of
2 Imports of capital goods refer here the imports of capital machinery and industrial raw materials.
3 We deflated nominal values of industrial output, imports of capital goods and private sector credit with the
GDP deflator (Base: FY1996=100). And real interest rate is calculated using Fishers’ equation: RIR= (Nominal
interest rate - CPI inflation rate).
-:10:-
industrial output (Y_IND), imports of capital goods (IMP_CG), private sector credit (PRC)
and real interest rate (RIR) of Bangladesh for the period FY1980 to FY2014 have unit roots
in level; only private sector credit (at 5% for Model B) and interest rate (at 10% for Model A)
reject null hypothesis. However, in first differences of all the variables, the PP tests statistics
reject unit roots at 1% level of significance and thus the variables are integrated of order one,
i.e., I(1) and the series become stationary in first differences. The test is robust and consistent
in all the series irrespective of their specifications. Thus the variables now qualify to examine
cointegration.

4.2 Cointegration and Vector Error Correction Estimation
In our four-variable case, the number of cointegration relation must be less than four. To
qualify this property we employ the Johansen cointegration approach under both Option 3
(linear deterministic trend in data assuming intercept without trend in cointegration equation
and in VAR) and Option 4 (linear deterministic trend in data with intercept and trend in
cointegration equation and no intercept in VAR). The selection of optimal lag length criterion
supports lag 1 based on the Akaike information criterion (AIC) and Schwartz Bayesian
criterion (SBC) through the estimation of unrestricted VAR with the for the analysis of
cointegration and VEC of the model (in Appendix Table A1).
-:11:-
In Appendix, Table A2 demonstrates the results of Johansen cointegration. The cointegration
rank of both the trace and maximum eigenvalue tests reveals an evidence of one cointegration
relationship among the variables under the Option 3; while under Option 4, trace test shows
two cointegration relationships in the model but the maximum eigenvalue test accords no
cointegration. Both options certainly indicate that there is an evidence of cointegrating
relationship among the variables of the model. However, option 3 produce robust results in
both the trace and maximum eigenvalue tests. The tests criterion recommends the existence
of the long-run relationship among the variables- industrial output, imports of capital goods,
private sector credit and real interest rate in the model.
We apply VEC model to estimate the cointegrating equation and to synthesize the long term
relationship between endogenous and exogenous variables in the model along with short-run
adjustment dynamics. Following the Equation 3, we find the estimated cointegrating equation
that stated in Equation 4. The equation shows the long-run cointegrating relationship between
industrial output which is considered as an endogenous one and imports of capital goods,
private sector credit and real interest rate which are exogenous variables in the model. At
equilibrium level, the estimated equation is normalized on industrial output and provides a
positive sign that is expected. The estimated cointegrating equation also exhibits that the
coefficients of explanatory variables such as imports of capital goods, private sector credit
and real interest rate are significant at 5 percent level and hence possesses expected signs.
The signs of the coefficients of the variables indicate that in the long-run, industrial output is
positively associated with the import of capital goods and private sector credit; while the
impact of real interest rate on industrial output performs an opposite one. This empirical
evidence supports the hypothesis that the import of capital goods and private sector credit
lead industrial output growth in the long-run in Bangladesh.
In the cointegrating equation 4, the value of the coefficient of imports of capital goods
indicates that an increase of 1% growth of imports of capital goods causes to an increase of
0.42% in industrial output growth. This supports the fundamental role of the import of capital
goods that fulfilling the shortage of capital machinery and industrial raw materials that finally
contribute to the growth of domestic industries of Bangladesh. Related to private sector
credit, the value of the coefficient shows that 1% increase in private sector credit causes
0.31% increase in industrial output growth. On the other hand, the value of the coefficient of
-:12:-
real interest rate indicates that 0.02% decrease of industrial output growth by 1% percentage
point change of real interest rate.
Cointegrating equation:
ect(t) = LnY_IND(t-1) - 0.42 LnIMP_CG(t-1) - 0.31 LnPRC(t-1) + 0.02 RIR(t-1) - 7.20 (4)

The error correction term (Table 2) on the regression with first differenced industrial output
addresses the short-run adjustment dynamics of the variables, if by any means the equilibrium
relationship is stunned. The estimated result exhibits that corresponding error correction term
on first differenced industrial output provides a negative sign as expected and significant at
the 1 percent level. The coefficients of first differenced private sector credit and real interest
rate are also significant at 5 percent level but the coefficient of imports of capital goods is
insignificant and posses a positive sign. Hence, in the process of error correction term of the
estimated VEC model, the significant coefficients of the variable industrial output along with
expected sign recommends that the endogenous variable perform well to adjust relationships
if by any means any disequilibrium once the system is shocked while imports of capital
goods do not so. The value of coefficient of the first-differentiated industrial output in the
estimated model -0.1075 indicates that only 10.75 percent of the last year’s disequilibrium is
corrected current year and that requiring 9.30 years to bringing the system into the steady
state if once it is distorted.
Moreover, in Appendix, Figure 3, the scatter diagrams and regression lines with the series of
LnY_IND, LnIMP_CG, LnPRC and interest rate also exhibit the long run relationships
among the variables. The relationship of industrial output with the imports of capital goods
and private sector credit looks highly positive association that indicates a strong
interdependence among these variables particularly for a country like Bangladesh. On the
-:13:-
other hand, industrial output and interest rate are negatively associated. From the diagram, we
also see that there is a positive association of imports of capital goods with private sector
credit.
4.3 Impulse Responses and Variance Decompositions
The realization of generalized impulse responses and forecast error variance decomposition
of industrial output derived from VECM, are presented in Appendix Figure 4 and Table A4.
Figure 4 presents that there exists a positive and very strong response on industrial output for
that of one standard deviation innovation in imports of capital goods and private sector credit.
On the other hand, one standard deviation innovation in real interest rate has a strong
negative and divergent impact on industrial output.
While impulse responses are very effective to measure the sign and magnitude of responses
to specific shocks, the variance decomposition analysis delivers a critical inside into the
relative importance of each variable in the system. According to the analysis of variance
decomposition we finds that share of the forecast error variance of industrial output decline
gradually for its own shock with increasing forecast horizon (Table A4 in Appendix), while
share of imports of capital goods and private sector credit increase slowly. Around 67 percent
of the forecast error variance of industrial output accounted for its own shock at 9 years. At
this time horizon remaining variability of industrial output accounted by the shock in imports
of capital goods (14%), private sector credit (11%) and real interest rate (8%). The outcomes
strongly support the results in VECM that estimated previously.
5. Conclusion
The evidence of time series analysis of our study supports that there exists a long-run
relationship among the variables of industrial output, imports of capital goods, private sector
credit and real interest rate in Bangladesh economy. The estimated result of the cointegrating
equation shows that imports of capital goods and private sector credit greatly promote
industrial output growth; while that of real interest rate performs an opposite one. Hence, the
finding establishes a hypothesis that in Bangladesh, in the long-run, imports of capital goods
lead the country’s economic growth through acceleration of the industrialization process that
is supported by related literatures of developing economies in Asia such as India, Indonesia,
-:14:-
Malaysia, Philippines, Singapore, Thailand and China where imports led growth through the
process of industrialization.
The justification of this growth hypothesis can broadly be categorized into four. First, imports
of capital machinery and industrial raw materials that use in domestic manufacturing
industries increase economic scale of industries and accelerate industrial output; finally
promotes economic growth. Second, as imported capital machinery and industrial raw
material raise domestic manufacturing output that accelerate exports; the multiplier effects of
foreign exchange receipts from the export of manufacturing products further contribute to
produce more for both domestic and foreign markets as of income effect. In fact, in
Bangladesh, exports of manufacturing products are considerably benefited from its industrial
output that depends on the import of capital machinery and industrial raw materials. Third,
capital goods and industrial raw materials are imported from technologically advanced
countries reasonably at low prices; it reduces the cost of production as well as increases
productivity of domestic manufacturing industries. Finally, imports of capital goods create
many positive externalities through the process of industrialization. On the other hand,
private sector credit also encourages private investment that evolves industrialization.
Through these channels, country’s industrialization process moves ahead and industrial
output grows faster that finally contribute to the growth of GDP.
From the evidence of our study, we strongly believe that like many other developing
countries, Bangladesh economy requires the import of capital goods to sustain the current
level economic growth through industrialization process as the country has a comparative
disadvantage in producing capital machinery and qualitative input materials. Moreover, to
attain a middle income status country by 2021 with aiming to increase employment and
reducing poverty, we have to achieve higher level of growth that should be sustainable.
Obviously, there is nothing any alternative except the acceleration of its industrialization
process. Thus, more liberalized trade, and export diversification and promotion policies along
with development of infrastructure and improvement of energy and power supply to attract
FDI and to set up international multination manufacturing industry would be the foremost
concern to the authority and policy makers in Bangladesh. These finding have policy
implications not only for Bangladesh, but also for other developing economies those desire to
grow fast. Finally, this paper raises an additional question that how we estimate the import
demand function for Bangladesh that left for future research.

Note: The λtrace and λmax are estimated as per Johansen (1988) and Johansen and Juselius (1990).
CV indicates critical values calculated for the 5 percent significance level and CE stands for number of
cointegration equation.
P-values presented in the parenthesis.
r denotes for the rank of the matrix, which indicates the number of the CE between the variables.
HO and HA indicate the null and alternative hypotheses respectively.
Option 3 includes an intercept without trend in the CE and the test VAR, whereas Option 4 includes an intercept
and a trend in the CE without any trend in the VAR.
The λtrace and λmax test statistics under both models are calculated by allowing for linear deterministic trends in
data.
** and
*** denote the significance of the statistics at 5% and 1% level respectively and rejects null hypothesis.
