The goal of this article is to investigate the determinants of bilateral trade flows of Bangladesh with
her fifty two major trading partners with the use of trade gravity model approach. The gravity model has been
estimated using pooled OLS, fixed effects, random effects estimation technique with the help of panel data for
the period 1975-2005. Our estimation results show that trade volume of Bangladesh responds more than
proportionally to per capita GDP and distance for OECD and NON –OECD trading partner countries
separately. Bangladesh’s direction of trade pattern is also strongly governed by geographical characteristics,
such as Area implying Bangladesh has a tendency to trade with larger countries. Membership in OECD and
GSP dummy has significant impact on trade. The results of gravity models have also been applied to calculate
the trade potentials indicating that Bangladesh has unexploited trade potentials with countries like UK,
Singapore, Netherlands, Germany, UAE, Canada, India, China, Italy, Australia, Germany, Switzerland &
Pakistan. We have found that the actual trade is converging towards equilibrium level of trade using average
speed of convergence measure. Therefore, identifying & utilizing unexploited trade potentials among some of
Bangladesh’s trading partners should stimulate growth to alleviate unemployment & poverty.
This paper analyzes the impact of high-end and low-end productive service agglomeration on
China's urban total factor productivity using panel data from 261 cities in China from 2003 to 2017, and divides
the country into three parts:
In recent years, Vietnam has joined international intergration by strong export agreements of bilateral and multilateral; Vietnam’s merchandise export in 1995 was only US $5.4 billion, in 2018 Vietnam’s merchandise export increased by 45 times compared to 1995 with US $244 billion. Vietnam’s imports increased by 29 times in 2018 compared to 1995. This study is an attempt to test a method of estimating the influence of exports on several Supply-sidefactors such as production value, value added and imports through the expansion of the standard system W. Leontief I.O and Miyazawa-style economic-demographic relations. This study also tries to make an experiment in the “Leontief Paradox”.The result is that Vietnam’s export value spread to production and imports but spread low to added value, especially in the processing industry group’s fabrication. The study is based on the non-competitive I.O table in 2012 and 2018 with 16 sectors.

The Relation Between Exports of Main Products And Economic Growth of Key Econ...inventionjournals
This paper clarifies the literature of key product export growth and regional economic growth. The paper analyses impacts of key product export on regional economic growth and vice versa. The paper provides recent empirical evidence of the relation. Besides an evaluation of the recent relation between export growth and economic growth in Viet Nam, the paper assesses the relation between key product export and economic growth during 1996-2012 period based on quantitative and qualitative approaches. With constructed models, the paper examines the relation between key product export and economic growth and concludes that it is positive. The research findings show that key product export in every economic region contributes positively to regional economic growth although it varies in different regions. Based on existing literature and empirical analysis, the paper provides a number of strategies to improve key product export contribution to key economic regions in the most effective manner and vice versa. The paper creates a fundament for researchers and policy makers both regionally and nationally in order for developing effective orientations, policies and measures for promoting export and sustainable eoconomic development.
External Trade Benefits and Poverty Reduction in English Speaking West Africa...iosrjce
This research examines the impact of external trade benefits on poverty reduction in five English
Speaking West African Countries (ESWACs) from 1980 to 2013. These countries include; The Gambia, Ghana,
Liberia, Nigeria and Sierra Leone). The study expressed external trade benefits (ETB) as increase in export
earnings (EXE), trade openness (TOP), total government expenditure (TGE) and reduction in foreign exchange
rate (FER), while poverty level is expressed as real gross domestic income (GNI) per capita current US Dollar.
Theoretically, the study relied on five trade theories, in practice; the study constructs a balanced panel data
structure (BPDS) and methodologically, departs from the classical OLS and 1st generation panel econometric
techniques to adopting recently developed 2nd generation panel data econometric methods. The results of the
study reveal that external trade benefits were not found to be significant enough to reduce the poverty level in
ESWACs from 1980 to 2013.This impliesthat external trade benefits did not significantly increase GNI per
capita in ESWACs within the period of study. Based on this result, the study therefore concluded that the impact
of external trade benefits on poverty level is a trivial matter because external trade benefits have not
comprehensively and significantly augmented the status of real gross domestic income (GNI) percapital
currentUSDollar of English speaking West African countries within the period of study. Following this
conclusion we recommended, among others, that policy implication on the result of co-integration of the panel

money into circulation with the aim of creating and expanding employment opportunities that would be able to
reduce poverty in the region and cut in public investment spending on agriculture and industrial sectors should

This study is about the impact of selected macroeconomic variables on economic growth of Bangladesh. Economic growth of Bangladesh is measured in terms of annual nominal GDP growth rate. Least squared regression model has been employed considering exchange rate, export, import and inflation rate as independent variables and gross domestic product as the dependent variable in this study. The results reveal that export and import have significant positive impact on GDP growth rate. The other variables (exchange rate and inflation) are not significant, indicating that there exists no significant relationship among the variables. The findings will help the policy makers to make policies concerning the country’s economic growth to remain robust in the near future.
An Analysis of Indian Commercial Dynamism in International Trade: 2000-2021Samsul Alam
The study first looks at the fundamentals of growth rate, trade balance, coverage rate, openness rate, and the share of global indicators before presenting each of them in more detail. It thus assesses India's overall commercial dynamism. A thorough analysis is made using data gathered from the World Bank's databank in order to carry out this study. An analysis of time series data is performed using data from 2000 to 2021. MS Excel is then used to analyze the data and provide a suitable interpretation. The results show that India has an average growth rate of 12.16 for imports and 12.02 for exports, a deficit trade balance over the years, a coverage rate that ranges from 78.49 (2012) to 97.97 (2020), trade openness that ranges from 26 (2001) to 56 (2012) percent, and a total global market share of 2.52 (2021) and 0.79. (2000). Researchers, other stakeholders in the field, and policymakers in nearby countries, specifically mentioning Bangladeshi, Pakistani, Myanmar and Indian governments, could all benefit from this study's findings.

This paper applies the Vector Autoregressive (VAR) technique to annual data from 1980 to 2013 to provide empirical evidence on the long-run relationship between export trade and economic growth in Malawi. The export trade in this study is disaggregated into services and goods exports. Thus, the paper estimated two models. The first model deals with the relationship between export of services and growth, and the other one determines the relationship between goods export and growth. While the paper finds no evidence for long-run relationship between export of services and goods on economic growth, the empirical results suggest existence of a short-run nexus between export of goods and economic growth in Malawi. The Granger causality test results have also confirmed existence of a unidirectional causality from goods exports to economic growth and another unidirectional causality from goods exports to service exports.

Monetary Policy Shocks and Agricultural Output Growth in Nigeriaiosrjce
This paper investigated the transmission channel of monetary policy shocks to agricultural output
growth over the period 1970 – 2012. Data were drawn from the Central Bank of Nigeria Statistical Bulletin,
2013. The study estimated a VAR model and showed that producers are able to effectively transfer increases in
cost of production to the final consumer through increased prices; and that though monetary policy shocks,
interest rate and consumer prices have dominant impacts on agricultural output growth in Nigeria, but that
monetary policy shocks transmitted through the interest rate channel are more effective. It was therefore
recommended that monetary policy efforts to revitalize the agricultural sector should focus more on the use of
differential interest rates amongst other policy tools.

US Economic Outlook - Being Decided - M Capital Group August 2021.pdfpchutichetpong
The U.S. economy is continuing its impressive recovery from the COVID-19 pandemic and not slowing down despite re-occurring bumps. The U.S. savings rate reached its highest ever recorded level at 34% in April 2020 and Americans seem ready to spend. The sectors that had been hurt the most by the pandemic specifically reduced consumer spending, like retail, leisure, hospitality, and travel, are now experiencing massive growth in revenue and job openings.
Could this growth lead to a “Roaring Twenties”? As quickly as the U.S. economy contracted, experiencing a 9.1% drop in economic output relative to the business cycle in Q2 2020, the largest in recorded history, it has rebounded beyond expectations. This surprising growth seems to be fueled by the U.S. government’s aggressive fiscal and monetary policies, and an increase in consumer spending as mobility restrictions are lifted. Unemployment rates between June 2020 and June 2021 decreased by 5.2%, while the demand for labor is increasing, coupled with increasing wages to incentivize Americans to rejoin the labor force. Schools and businesses are expected to fully reopen soon. In parallel, vaccination rates across the country and the world continue to rise, with full vaccination rates of 50% and 14.8% respectively.
However, it is not completely smooth sailing from here. According to M Capital Group, the main risks that threaten the continued growth of the U.S. economy are inflation, unsettled trade relations, and another wave of Covid-19 mutations that could shut down the world again. Have we learned from the past year of COVID-19 and adapted our economy accordingly?
“In order for the U.S. economy to continue growing, whether there is another wave or not, the U.S. needs to focus on diversifying supply chains, supporting business investment, and maintaining consumer spending,” says Grace Feeley, a research analyst at M Capital Group.
While the economic indicators are positive, the risks are coming closer to manifesting and threatening such growth. The new variants spreading throughout the world, Delta, Lambda, and Gamma, are vaccine-resistant and muddy the predictions made about the economy and health of the country. These variants bring back the feeling of uncertainty that has wreaked havoc not only on the stock market but the mindset of people around the world. MCG provides unique insight on how to mitigate these risks to possibly ensure a bright economic future.
The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.

The future of the Pi cryptocurrency is uncertain, and its success will depend on several factors. Pi is a relatively new cryptocurrency that aims to be user-friendly and accessible to a wide audience. Here are a few key considerations for its future:
Message: @Pi_vendor_247 on telegram if u want to sell PI COINS.
1. Mainnet Launch: As of my last knowledge update in January 2022, Pi was still in the testnet phase. Its success will depend on a successful transition to a mainnet, where actual transactions can take place.
2. User Adoption: Pi's success will be closely tied to user adoption. The more users who join the network and actively participate, the stronger the ecosystem can become.
3. Utility and Use Cases: For a cryptocurrency to thrive, it must offer utility and practical use cases. The Pi team has talked about various applications, including peer-to-peer transactions, smart contracts, and more. The development and implementation of these features will be essential.
4. Regulatory Environment: The regulatory environment for cryptocurrencies is evolving globally. How Pi navigates and complies with regulations in various jurisdictions will significantly impact its future.
5. Technology Development: The Pi network must continue to develop and improve its technology, security, and scalability to compete with established cryptocurrencies.
6. Community Engagement: The Pi community plays a critical role in its future. Engaged users can help build trust and grow the network.
7. Monetization and Sustainability: The Pi team's monetization strategy, such as fees, partnerships, or other revenue sources, will affect its long-term sustainability.
It's essential to approach Pi or any new cryptocurrency with caution and conduct due diligence. Cryptocurrency investments involve risks, and potential rewards can be uncertain. The success and future of Pi will depend on the collective efforts of its team, community, and the broader cryptocurrency market dynamics. It's advisable to stay updated on Pi's development and follow any updates from the official Pi Network website or announcements from the team.
how to sell pi coins in South Korea profitably.DOT TECH
Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.

Abstract: The goal of this article is to investigate the determinants of bilateral trade flows of Bangladesh with
her fifty two major trading partners with the use of trade gravity model approach. The gravity model has been
estimated using pooled OLS, fixed effects, random effects estimation technique with the help of panel data for
the period 1975-2005. Our estimation results show that trade volume of Bangladesh responds more than
proportionally to per capita GDP and distance for OECD and NON –OECD trading partner countries
separately. Bangladesh’s direction of trade pattern is also strongly governed by geographical characteristics,
such as Area implying Bangladesh has a tendency to trade with larger countries. Membership in OECD and
GSP dummy has significant impact on trade. The results of gravity models have also been applied to calculate
the trade potentials indicating that Bangladesh has unexploited trade potentials with countries like UK,
Singapore, Netherlands, Germany, UAE, Canada, India, China, Italy, Australia, Germany, Switzerland &
Pakistan. We have found that the actual trade is converging towards equilibrium level of trade using average
speed of convergence measure. Therefore, identifying & utilizing unexploited trade potentials among some of
Bangladesh’s trading partners should stimulate growth to alleviate unemployment & poverty.
Keywords: Gravity Model, Panel data, Fixed effects Model, Bangladesh’s trade
I. Introduction
The possible set of factors affecting a country‟s direction of trade (DOT) can be quite large,
incorporating many aspects of its existence. Some of the important economic factors are comparative advantage
relative to the other countries, economies of scale, the aggregate income of home country as well as partner
residents, government policies especially related to trade & exchange rate , membership to currency unions and /
or customs unions & finally, participation in bilateral, regional & multilateral agreements.
The theory of gravity which is a very successful empirical economic theory borrowed from the
Newtonian law of gravity, states that trade flows between two countries increases with the product of their gross
domestic products (GDP) & decreases with the distances between them. In the literature there have been several
attempts to derive this relationship between trade, GDPs & distance from theoretical considerations. It has been
shown that the positive relationship with the GDPs & the negative relationship with distance can be established
from a variety of assumptions regarding the structure of production & preferences. Using the model as a
benchmark implicitly implies that it accounts for some of the more important natural reasons for trade.
Additional factors come in to explain what remains unexplained after these natural factors have taken their
course.
Another important contribution of the gravity model is the importance that it assigns to distance. From
neo classical models of international trade from Smith to Heckscher-Ohlin & their extensions, transport costs
were substantial & their could be no doubt that these costs played a role in determining the flow of commodities
between countries. Thus the issue of distance as a determinant of trade flows is still an open issue & the gravity
model is perhaps the only model that addresses the issue explicitly.
In this paper we have tried to evaluate the influence of the three variables suggested by the gravity
theory in determining Bangladesh‟s DOT. We also attempt some simple extensions of the „core‟ gravity model
by adding dummies & additional variables for size in the basic structure.
II. Review of The Literature
Alam, Uddin & Taufique (2009) used panel estimation technique to study import inflows of
Bangladesh covering annual data & eight major trading partners from 1985 to 2003 & found that the population
(market size) of Bangladesh has significant impacts on imports. This paper also found that partner countries‟
GDP has significant positive impacts & partner countries‟ population has mixed impact on imports of
Bangladesh. The geographical distance of Bangladesh with her partner countries has significant negative
impacts on its import.
Rahman (2004) applied a generalized gravity model to analyze Bangladesh‟s trade flow with her
trading partners using the panel data estimation techniques. The study estimated the gravity model of trade (sum

of imports & exports). The results showed that Bangladesh‟s trade is positively determined by the size (GNP) of
the economies, per capita GNP differential & openness of the trade partners.
Batra (2004) estimated the trade potential for India using the gravity model approach. This study has
used an augmented gravity model to first analyze bilateral trade flows between India & all her trading partners
(one hundred & forty six countries). The gravity model has been estimated using the ordinary least squares
(OLS) estimation technique covering cross section data for the year 2000. The estimation results showed that the
gravity equation fits the data well, explaining about 70% of the variation in bilateral trade across the sample of
countries. It delivers precise & plausible measurement of income & distance elasticities & estimates for other
geographical, cultural & historical characteristics.
Blomquist (2004) applies gravity model to explain the trade flow of Singapore and as usual with
gravity model,a very high degree of explanation is achieved especially for the GDP and distance variable.
Anaman & Al-Kharusa (2003) on the other hand show that in a gravity model framework, the
determinant of Brunei‟s trade with EU is mainly from the population of Brunei & EU countries.
Filippini (2003) used the gravity equation model to analyze trade flows between East Asian
industrialization countries including China & some developed countries some EU countries, & Japan from 1970
to 2000.In this paper the signs of the GDP‟s are positive, showing that wealthier countries trade more. For the
population variables, they obtain a negative coefficient for the developing ones. Bilateral trade flows are
negatively correlated with the geographical distance. The analysis of the manufacturing exports from the
developing industrialized countries to developed industrializing ones shows developing countries GDP is
positively correlated with the flows of exports. But Developed countries GDP is not statistically significant. The
population of the newly industrialized countries shows a negative coefficient.The population of the developed
country is positively correlated with the flow of exports and is statistically significant. The coefficients of the
geographical distance are negative.
Jordan & Eita (2007) analyzed the determinants of exports of wood & articles of wood using a
gravity model approach for South Africa from 1997 to 2004 including sixty eight main trading partners. They
found that an increase in the importer‟s GDP causes an increase in the exports of South Africa‟s wood products.
The coefficient of South Africa‟s GDP has a negative & significant sign, & this is not consistent with the theory.
South African population has a significant and positive coefficient on the exports of wood products.The
importer‟s population has a negative & statistically significant effect on the exports of wood products. Distance
has a negative & insignificant effect on wood products. The results are supported by the theory, also comparable
to the estimates by Sapir (1981).
Coe & Hoffmaister (1999) estimated a gravity model to address the question of whether Africa‟s
bilateral trade with industrial countries is „unusual‟ compared to other developing country regions. They used
data on bilateral trade between eighty four developing countries & twenty two industrial countries over the full
1970-95 period. The estimated coefficients on the economic mass variable (YiYj) are positive, indicating that
holding other things constant, trade tends to increase roughly proportionally with GDP in developing countries,
the coefficient on the product of per capita GDPs‟ (YiYj/PiPj) has positive sign & statistically (proxy for stage of
development / economic growth) significant. The estimated coefficient on distance is negative. Finally, it was
concluded that Africa‟s relatively low level of bilateral trade with industrial countries is mainly due to the
relatively small size of the average African economy & the relatively low rates of economic growth since 1970.
Longo & Sekkat (2001) estimated the intra African trade using a gravity model taking forty one
African countries into consideration, over the period 1980-97. They found that the size (GNP) of a country‟s
economy is an important determinant of bilateral trade. The coefficients for per capita income show that the
propensity to export to other African countries declines as incomes rise, which reflects the fact that richer
African countries specialize in goods for which there is scarce demand by their neighbors. Distance has the
expected negative impact on intra-African trade.
Martinez & Lehmann (2003) applied gravity model to annual bilateral exports between twenty
countries: Mercosur and Chile & the fifteen current members of the EU, from 1988 to 1996. It should be noted
that Argentina, Brazil, Paraguay & Uruguay signed the Mercosur agreement in 1991 & it went into effect in
1995 becoming a customs union. They found that exporter & importer income, have a positive influence on
bilateral trade flows. Exporter population has a large & negative effect in exports showing a positive absorption
effect, whereas importer population has a large & positive effect on exports, indicating that bigger countries
import more than smaller countries. Bergstrand (1985) estimated the generalized gravity equation for fifteen
OECD countries‟ trade flows for 1965, 1966, 1975, 1976. GDP variable has significant, positive effect on trade
flows. Distance & contiguous area have significant negative effect on trade flows.
Egger (2002) used the gravity model to analyze the exports flows of OECD countries to other OECD
members & the ten central & Eastern European countries over the period 1986-1997. He found that bilateral
sum of GDP, country size, difference in relative factor endowments have significant effect on trade. He also
found that distance had significant negative effect on trade.

Caetano & Galego (2006) estimated a gravity model for the period 1993-2001, considering data on EU
& CEEC countries to analyze total bilateral exports (central & East European countries). The estimates support
the idea that the size of the economy has a statistically positive influence on bilateral trade relations. On the
other hand, countries‟ economic distance seems to have a negative impact on bilateral trade flows.
There is a huge number of empirical applications in the literature of international trade, which have
contributed to the improvement of performance of the gravity equation. First in recent papers, Mátyás (1997),
Cheng & Wall (1999) & Breuss & Egger (1999) & Egger (2000) improved the econometric specification of the
gravity equation. Second, Bergstrand (1985), Helpman (1987), Wei (1996), Soloaga & addition of new
variables. Winters (1999), Limao & Venables (1999) & Bougheas et al (1999) among others contributed to the
refinement of the explanatory variables considered in the analysis & to the addition of new variables.
III. Sample Size and Data Issues
Our study covers a total of fifty two trading partners of Bangladesh. The countries are chosen on the
basis of importance of trading partnership with Bangladesh & availability of required data. The list of the
countries included in the sample is given in Table 6.1.The annual data for all variables have been collected for
the period from 1975 to 2005 (31 years). The trade flow data has been collected from the “Direction of Trade”
(DOT) CD-ROM data set developed by the IMF. Bilateral trade flow data on FOB exports & CIF imports in
nominal American dollars are used. We have deflated trade by the American CPI data for all urban consumers
(2000=100) taken from WDI CD-ROM 2007, Published by the World Bank. Since our focus is on total trade
rather than exports or imports, we measure bilateral trade between a pair of countries by averaging all of the
(four possible) measures potentially available (exports from i to j, imports into j from i, exports from j to i,
imports into i from j). Since the four possible measures finally reduces to two measures, we estimate the
volume of trade by adding exports from i to j to imports into j from i and divide it by 2.Real GDP PPP (constant
2000 international $) data & Population data have been obtained from world development indicators CD-ROM
2007 & Penn World Table (PWT) 6.3 respectively. Data on Landlocked countries, Islands, Area, distance have
been collected from google earth website. Here distance is measured between the capitals of country i & country
j in miles. In our data, we have land border/Contiguous area only with India, number of Landlocked countries
are Austria, Hungary, Swaziland, Switzerland respectively & number of Islands are UK, SriLanka, Singapore,
Philippines, Papua New Guinea, New Zealand, Japan, Ireland, Indonesia & Australia. All countries included in
the sample are members of WTO except four countries (Algeria, Iran, Sudan & Syria). Bangladesh gets GSP
facilities from Australia, Canada, EU, Japan, New Zealand & Switzerland.Real GDP PPP, population, exports &
imports data of Bangladesh all are in millions & area is in square miles.
IV. Methodology
Recognizing the nature of trading flows between countries as relationships that develop & change over
time, there is an increasing use of panel (longitudinal) data approaches to the estimation of gravity models &
this method is chosen in this paper. The use of different panel data methods, such as random or fixed (within)
effects estimators, allows for various assumptions regarding trade flows to be analyzed & tested.
We will control for cultural, historical & political factors using a fixed effects model that assumes that
there are fixed pair-specific factors that may be correlated with levels of bilateral trade & with the right hand
side variables. We assume that the gravity equation for a country pair may have a unique intercept & that it may
be different for each direction of trade. However, we retain the assumption of the pooled cross section model
that the slope coefficients are constant over time & across trading pairs. The country pair intercepts include the
effects of all omitted variables that are cross-sectionally specific but remain constant over time, such as distance,
contiguity, language, culture etc. The time dummies are included to capture the effects of any variable affecting
bilateral trade that vary over time & that are constant across country pairs & have not been included in the list of
explanatory variables.
The most common method for measuring distance is to simply measure it between the capital cities of
the two countries to capture transportation & information costs (Head & Mayer 2001), There are problems with
this, such as the implicit assumptions that overland transport costs are the same as those over sea, & that all
overland/oversea distances are equally costly. Our fixed-effects approach eliminates the need to include a
distance variable, as it control for all variables that do not change over time.
Another difficulty with standard measures of economic distance is the common assumption that the
capital city is a useful proxy for economic center. While this may be useful for small countries with one major
city, it is wide of the mark for countries like Canada & the U.S., which have major cities thousands of miles
apart on different oceans, & which serve as centers for trade with completely different countries. As the U.S. has
the highest GDP & the highest volume of trade, the wrong measure of economic distance can bias the estimation
of the coefficients on the other variables in the gravity model. Another advantage of our approach is that it
removes the problem of controlling for contiguity. Although it is potentially important, as a great deal of the

DOI: 10.9790/5933-06320114 www.iosrjournals.org 4 | Page
trade can occur from people crossing the border to make everyday purchases, it is accounted for only
sometimes. Even when it is accounted for with a dummy variable as we have done, it still assumes that all
contiguity is equivalent (does not matter so much for our sample as Bangladesh has contiguous area only with
India) & time-invariant in terms of its effect on trade.
When unobservable country pair effects & unobservable time effects are assumed to be fixed
parameters to be estimated & the explanatory variables are considered to be independent of error term, then we
have fixed effects error component model. When the unobservable country pair effects & the unobservable time
effects are treated as random variables, we have random effects model. In the random effects model, the
explanatory variables are assumed to be independent of errors, unobservable country-pair effects &
unobservable time effects. Here unobservable country-pair effects & errors are assumed to follow a common
distribution with zero mean & constant variance & unobservable country-pair effects are assumed to be
independent of errors. As the cross-section effects follow a common distribution with zero mean & constant
variance, individual effects/ cross-section effects are not estimated separately. This prevents the loss of degrees
of freedom which happens with the fixed effects estimation.
The inclusion of country pair fixed effects doesn‟t allow the estimation of the coefficients of the
variables which are time-invariant like geographic distance, the existence of frontier, number of Islands, number
of Landlocked countries, Area & so on. Therefore we use a two step procedure proposed by Arellano & Bover
(1990) in order to obtain these coefficients. This procedure consists on a regression of the country-pair effects
obtained in the within estimation on the time invariant explanatory variables.
4.1 Model Specification
In order to study the bilateral trade relations between Bangladesh & her fifty two trading partners, we
have estimated a gravity model for the period 1975-2005. In this paper, following previous studies (Rose 2003)
bilateral trade flows are modeled as a function of distance between i (Bangladesh) & j (trading partners), log of
GDP of country i & j, log of per capita GDP of country i & j, log of area of country i & j. We have also included
the existence of a common border, number of Landlocked countries, number of Islands, GSP facilities, civil
liberty & membership in WTO & OECD.
Therefore, the exact specification of the gravity model used in the paper is as follows:
ln (Xijt)=β0+β1lnDij+ β2ln (YiYj)t + β3 ln (YiYj/Pop iPopj)t + β4 Cont ij+ β5 Landlij+ β6 IsLandij + β7 ln
(AreaiAreaj)+ β8 GSPijt +ΣtδtTt+φ1WTO2ijt+ ф2OECD1ijt+ β9ln(cli+clj)t+ξijt…...(1)
Where i & j denote trading partners, t denotes time, β and δ are vectors of coefficients, Xijt denotes the
average value of real bilateral trade between countries i & j at time t, Y is real GDP PPP (constant 2000
international $), Pop is population, D is the distance between i & j, Cont is a binary variable which is unity if i
& j share a land border, Landl is the number of Landlocked countries in the country pair (0, 1 or 2),Island is the
number of Island nations in the pair (0, 1 or 2),Area is the Area of the country, GSP is a binary variable which is
unity if j extended a GSP concession to i at t, WTO2ijt is a binary variable which is unity if both i & j are
GATT/WTO members at t, OECD1ijt is a binary variable which is unity if either i or j is an OECD member at
t.Here cli and clj are civil liberty of i and civil liberty of j respectively. Civil liberties are measured on a one to
seven scale, freedom index scores are categorized as follows, Free-countries with a score of 1& 2;Partly Free-
countries with a score of 3 & 4; Not free-countries with a score of 5,6 &7 and ξijt represents the omitted other
influences on bilateral trade, assumed to be well behaved.
The above mentioned model is estimated taking fifty two main trading partners of Bangladesh into
consideration, from 1975 to 2005. This model is estimated again taking only OECD trading partners of
Bangladesh (twenty four countries) into account. The model is as follows:
ln(Xijt)=β0+β1lnDij+ β2 ln(YiYj)t + β3 ln (YiYj/PopiPopj)t + β4Landlij+ β5 IsLandij + β6 ln(AreaiAreaj)+ β8 GSPijt +
β9 ln(cli+clj)t………………………………(3)
This model differs from model 1 because, Cont=0, as we have contiguous area only with India within
the sample, & WTO2 = intercept, OCED1 = intercept.That is both WTO2 & OCED1 are multicollinear with the
intercept, therefore have been dropped from this model as all OECD trading partner countries are members of
WTO & OECD.
We have estimated model 1 again taking only Developing countries (twenty eight countries) into
consideration. This model is as follows:
ln(Xijt)=β0+β1lnDij+β2 ln(YiYj)t + β3 ln (YiYj/PopiPopj)t + β4 Contij+ β5 Landlij+ β6 IsLandij + β7 ln(AreaiAreaj)+
φ1 WTO2+ β9 ln(cli+clj)t ………………………(5)
5. Does the Gravity Model Explain Bangladesh’s Direction of Trade? A Panel Data Approach
DOI: 10.9790/5933-06320114 www.iosrjournals.org 5 | Page
For this model, GSP & OECD1 dummies are zero because trading partners are only developing
countries, most of the countries take GSP (general system of preferences) facilities from developed/OECD
countries & are not members of OECD.
These three models 1, 3 & 5 have been estimated excluding the time-invariant variables, separately.
That is model 1 is estimated again as the following model:
ln(Xijt)=β0 + β1 ln(YiYj)t + β2 ln (YiYj/PopiPopj)t + β3 ln(cli+clj)t………………………………(2)
Similarly, model 3 is estimated again excluding the time invariant variables, which is the following model:
ln(Xijt)=β0 + β1 ln(YiYj)t + β2 ln (YiYj/PopiPopj)t + β3 ln(cli+clj)t…………………………………(4)
here, WTO2 & OECD1 are multicollinear with the intercept as trading partners are OECD countries.And model
5 is estimated similarly (dropping the time in-variant variables) & we get model (6), which is as follows:
ln(Xijt)=β0 + β1 ln(YiYj)t + β2 ln (YiYj/PopiPopj)t + β3 ln(cli+clj)t ………………………(6)
Distance, contiguous area, Landlocked countries, Islands, Area all are time-invariant variables undoubtedly.
For our data set, GSP is also a time invariant variable because Bangladesh receives GSP facilities from
Australia, Canada, EU, Japan, New Zealand & Switzerland & UK in different time. Bangladesh receives GSP
facilities from Australia since 1995, from Canada since 1995, from EU since 1990‟s, from Japan since 1972,
from New Zealand since 2000, from UK since 1973. We have assumed that Bangladesh receives GSP facilities
from these countries since 1975 & continues up to 2005. Therefore it has become time-invariant variable.
Similarly, All trading partners except, Sudan, Syria, Algeria & Iran are members of WTO & all member
countries in our sample have become member of GATT/WTO before 1975. So, WTO2 dummy is also time
invariant. Similar argument applies to OECD1 dummy variable. Almost all OECD members have become
members of this organization before 1975, therefore, OECD1 dummy is time invariant variable.
V. Results & Interpretation
5.1. Regression Results for all Countries
We see that the coefficients of distance variable are economically & statistically significant at 1%
level with negative (expected) sign & greater than 1 for pooled OLS & random effects estimation in Table 5.1.1
which shows results of pooled OLS estimation, fixed effects estimation & random effects estimation for model
1. Trade distance elasticity is -1.88%, implying if the distance between Bangladesh & her trading partner
increases by 1%, trade volume declines by 1.88%, ceteris paribus on an average index (more than
proportionally) for pooled OLS estimation. However, the estimated coefficients become bigger in random
effects estimation. Trade distance elasticities are -2.19% & -2.18% for one way random effects estimation & two
way random effects estimation respectively. So, coefficient of distance increases in absolute term from -1.88%
to -2.19% & -2.18%. It can be said that, when country specific heterogeneity is considered this trade distance
elasticity will become larger compared to the pooled OLS estimate .
The product of country i & j gross domestic product in time t is used as a direct measure of the
economic mass & since trade is an interacting process, the product is meant to present the economic mass in an
“interactive way”. This variable is expected to be positively & significantly related to trade. It embodies factors
that effect potential supply of exporting countries & potential demand of importing countries, as both are
positive functions of national income (GDP). The pooled OLS estimate of GDP variable is significant at 1%
level & two way fixed effects estimate of GDP variable is significant at 10% with unexpected (negative) sign.
The one way fixed effects estimate & random effects estimates of GDP variable aren‟t significant.
The coefficients of per capita GDP variable (PCGDP is the proxy for level/stage of development) are
significant at 1% level with positive sign for all estimation methods. The trade PCGDP elasticities are 1.40%,
1.55%, 1.12% & 1.11% for fixed effects & random effects estimations, implying as the product of PCGDP of
the two countries increases by 1%, trade increases by 1.40%, 1.55%, 1.12% & 1.11% respectively. As the
coefficient of PCGDP variable is always greater than 1, trade volume increases more than proportionally with an
increase in the economic development of the combined entity defined by the two countries. The pooled OLS
estimate (0.70) of PCGDP variable is also significant at 1% level which is lower than fixed effects & random
effects estimates of PCGDP.

All variables are expressed in natural logarithms. t statistics are in parentheses.*** denote significance at 1%,

The pooled OLS estimate of Cont variable is -0.50 (with negative sign), significant at 10%, whereas,
the variable isn‟t significant in random effects estimation. The Landl & Island variables are not significant but
the estimated coefficients of these variables give correct (negative) sign. Another variable representing
geographical characteristics, Area is always significant at 1% level with positive sign. The pooled OLS, one way
& two way random effects estimates of Area are 0.26, 0.52 & 0.51. Therefore, as the Area between two trading
partners increases by 1%, trade increases by 0.26%, 0.52% & 0.5% on an average index. The pooled OLS
estimate of Area is smaller than random effects estimates of Area. The GSP variable is not significant but gives
correct sign in pooled OLS estimation & unexpected sign in random effects estimation due to collinearity (0.64)
between PCGDP & GSP variable. WTO2 variable is not significant, but gives correct sign in random effects
estimation & unexpected sign in pooled OLS estimation. Pooled OLS & random effects estimates of OECD1
variable are not significant but do give correct sign. Cl variable is not significant but gives correct sign for
pooled OLS, fixed effects & random effects estimation.
The R2
of both one way & two way fixed effects estimation is 0.84, implying 84% of the variation in
the dependent variable is explained by the independent variable. This R2
is greater than the R2
from pooled OLS
& random effects estimation, which are 0.63, 0.26 & 0.21 respectively. We check the poolability of this model
by F test which is significant at 1% level & rejects the hypothesis that the country specific effects are jointly
zero. The F tests for both one way fixed effects & two way fixed effects are significant at 1% level implying that
there exist country specific fixed effects. The Hausman test statistic for both one way & two way random effects
are significant at 1% & 5% level respectively, implying fixed effects estimation is preferred to random effects
estimation, rejecting the null hypothesis of no correlation between the country specific effects & time specific
effects & regressors. Therefore, fixed effects model is a better choice than random effects model as we are
interested in estimating typical trade flows between an ex ante predetermined selection of nations (Egger, 2000).
The Breuch Pagan lagrangian multiplier test statistic (LM test) is significant at 1% level rejecting the null
hypothesis of zero error variance. This test confirms the fact that, random effects estimation is a better choice
compared to pooled OLS estimation.
If we consider model 2, we see pooled OLS estimate of GDP variable is significant at 1% level. Both
one way & two way random effects estimates of GDP variable are significant at 10% level. But fixed effects
estimates (both one way & two way) of GDP variable are neither significant nor give expected sign, almost
similar to the findings of model 1‟s GDP variable. The pooled OLS , fixed effects & random effects estimates of
PCGDP variable are significant at 1% with positive (correct) sign. The trade PCGDP elasticities are 1.40% &
1.55% for one way & two way fixed effects estimations implying trade increases more than proportionally with
an increase in the economic development of the combined entity defined by the two countries. The coefficients
of PCGDP variable of fixed effects estimation are similar to model 1 given in Table 5.1.1. But the coefficients

of PCGDP variable of pooled OLS & random effects estimations of model 2 are smaller than model 1‟s pooled
OLS & random effects estimates of PCGDP variable. Fixed effects & random effects estimates of civil liberty
variable are not significant (Cl) but do give correct sign (negative). The coefficients of one way & two way
fixed effects estimations of GDP variable are negative for both model 1 & 2, because there is moderate
collinearity (0.48) between GDP & PCGDP variable. R2
of both one way & two way fixed effects estimations is
0.84. For model 2, all F tests are significant at 1%. Poolability of model 2 is rejected at 1% level. Both one way
& two way country specific fixed effects exist (F tests are significant at 1% level). Both Hausman test statistic &
LM test statistics are significant at 1%, confirming the fact that fixed effects estimation is preferred to random
effects estimation & random effects estimation is preferred to pooled OLS estimation.
5.2. Regression Results for OECD countries:
If we consider model 3, we see that trade distance elasticity is significant at 1% with correct (negative)
sign for all estimation methods. Pooled OLS estimate of GDP variable is significant at 1% & two way random
effects estimate of GDP variable is significant at 10%. Two way fixed effects estimate & one way random
effects estimate of GDP variable are not significant, but do give correct sign. But one way fixed effects estimate
of GDP variable is neither significant nor gives correct sign, due to moderate collinearity between GDP &
PCGDP (0.41) and GDP & Area (0.46). Pooled OLS, one way fixed effects & random effects estimates of
PCGDP variable are 0.56, 2.02, 1.00 & 0.96, all are significant at 1% level & two way fixed effects estimate of
PCGDP variable is 1.85, which is significant at 10% level . Only fixed effects (one way) estimate of trade
PCGDP elasticity is greater than 1, implying trade increases more than proportionally with an increase in the
economic development of the combined entity defined by the two countries. Estimates of Landl variable do give
correct sign (negative) for pooled OLS & random effects estimations. Estimated coefficients of Landl variable
do give correct sign (negative) for pooled OLS & random effects estimations but are insignificant.
Random effects estimates of Island variable are neither significant nor give correct sign whereas Pooled
OLS estimate of Island variable is significant. Pooled OLS estimate of Area variable is significant at 1% &
random effects estimate of Area variable is significant at 10%. GSP variable is not significant & gives
unexpected sign for random effects estimation.
Pooled OLS estimate of Cl variable is significant at 1% with correct sign, implying as the Cl between
Bangladesh & her trading partner increase by 1% (here, higher value of civil liberty index indicates lower
freedom), trade declines by 1.3%, ceteris paribus. Fixed effects estimate & random effects estimates of civil
liberty variable are not significant but do give correct sign. R2
of pooled OLS, fixed effects & random effects
model (both one way & two way) are 0.65, 0.88, 0.88, 0.43 & 0.35. All F tests are significant at 1% level,
rejecting the poolability of the model & accepting the fact that there exist both one way & two way fixed effects.
Hausman test statistic & LM test statistic are significant at 1%, indicating that fixed effects estimation is
preferred to random effects estimation & random effects estimation is preferred to pooled OLS estimation.

All variables are expressed in natural logarithms. t statistics are in parentheses.*** denote significance at 1%,

Analyzing equation 4,we see pooled OLS estimate of GDP variable is significant at 1% level, random
effects estimates of GDP variable are significant at 10% & 5% level (both one way & two way). Two way fixed
effects estimate of GDP variable isn‟t significant but gives correct sign. But one way fixed effects estimate of
GDP variable is neither significant nor gives correct sign, due to collinearity between GDP & PCGDP
(0.41).The pooled OLS, one way fixed effects, two way fixed effects,one way random effects ,two way random
effects estimates of PCGDP are (trade PCGDP elasticity) 0.46%,2.02%,1.85%, 0.73% & 0.71% with correct
(positive) sign, significant at 5%,5%,5%,10%,10% respectively. Fixed effects estimates of (both one way and
two way) PCGDP are greater than 1,whereas pooled OLS and random effects estimates are less than 1. Fixed
effect estimates of PCGDP are 2.02% & 1.85%, implying trade increases more than proportionally with an
increase in the economic development of the combined entity defined by the two countries. Pooled OLS
estimate of civil liberty variable is significant at 5% whereas, other estimates of this variable are not
significant.R2
of pooled OLS, fixed effects & random effects are 0.58, 0.88, 0.88, 0.42 & 0.34. All F tests are
significant at 1%, rejecting the poolability of the model & confirms the fact that both country & time specific
heterogeneity exist. Hausman test & LM test statistics are significant at 1% & confirms the fact that fixed effects
estimation is preferred to random effects estimation & random effects estimation is preferred to pooled OLS
estimation.
5.3. Regression Results for NON-OECD Countries:
Table 5.3.5 shows that trade distance elasticities are -2.15%, -2.29% & -2.29% for pooled OLS, one
way random effects & two way random effects estimation & significant at 1% level with correct (negative) sign.
Trade distance elasticity of pooled OLS implies if the distance between Bangladesh & her trading partner
increases by 1%, volume of trade declines by 2.15%, ceteris paribus. Trade distance elasticities of one way &
two way random effects imply if the distance between Bangladesh & her trading partner increases by 1%, trade
declines by an average index of 2.29% & 2.29% respectively. For this model, trade volume responds more than
proportionally to distance (since, the coefficient is greater than 1).
Pooled OLS, fixed effects & random effects estimates of GDP variable are not significant & do give
unexpected sign for fixed & random effects estimates due to collinearity between GDP & Area (0.69). Even if
we drop Area & estimate model 5 again, pooled OLS estimate of GDP variable is significant with correct sign
but fixed effects estimates of GDP variable (both one way & two way) are still insignificant with unexpected
sign. The pooled OLS, one way fixed effects & random effects estimates (both one way & two way) of PCGDP
variable are significant at 1% & two way fixed effects estimate of PCGDP variable is significant at 5% level
with correct sign. For model 5, trade PCGDP elasticities of one way & two way fixed effects estimations are
greater than 1, that is trade responds more than proportionally to PCGDP. Here also these fixed effects estimates
imply that trade increases more than proportionally with an increase in the economic development of the
combined entity defined by the two countries. The pooled OLS & random effects estimates of Cont variable are
not significant, but do give negative sign.
The pooled OLS estimate of Cont variable is also negative for model 1. As we are considering model 5,
which takes into account developing countries as their trading partners, we would say that trade between
Bangladesh & India (India is the only country in our data that shares border with Bangladesh) is not reported, as
there is a huge amount of illegal trade across the porous borders. Thus, there is bound to be a lot of reporting
biases in the data. This negative sign can thus also be put down to errors in observations. Bangladesh does not
have very cordial relations with India.

Thus political factors also have their due share in the sign. Moreover, we have checked the correlation
matrix, which shows Cont variable doesn‟t have any collinearity with other variables worth mentioning. The
estimated coefficient of Cont is 0.08 means that, when the dummy is equal to 1, volume of trade decreases,
ceteris paribus by 8.3% (e0.08
-1=0.083). If we consider the random effects estimate of Cont variable, which
implies when the dummy is equal to 1, trade volume decreases, ceteris paribus by 24.6% (e0.22
-1=0.246) as both
one way & two way random effects coefficients of Cont dummy is -0.22. Moreover, Cont dummy has no
collinearity worth mentioning with any other variables for both models 1 & 5 (two models, which contain Cont
variable). Estimates of Landl variable are neither significant nor do give expected sign.
Pooled OLS estimate of Island variable is significant at 1% level with correct (negative) sign & one
way & two way random effects estimates of Island variable are not significant with correct (negative) sign.
Pooled OLS & random effects estimates of Area variable are significant at 1% level with correct sign.
The estimates are 0.49, 0.56 & 0.55, implying, if the Area between Bangladesh & her trading partner increases
by 1%, trade increases by 0.49%, 0.56% & 0.55%. So, there is a tendency for Bangladesh to trade more with
larger countries.
Though pooled OLS estimate of WTO2 variable is significant at 5% level, random effects estimates of
WTO2 variable are not significant. Fixed effects & random effects estimates of civil liberty variable have
correct sign (negative), but insignificant. Though Hausman test is insignificant at 10% level, overall goodness of
fit (R2
) is 0.80 for both one way & two way fixed effects models, implying 80% of the variation in the
dependent variable is explained by the independent variables. F tests for both one way & two way fixed effects
are significant at 1% level suggesting that fixed effects estimation is preferred to random effects estimation. As
usual, the LM test is significant at 1% level implying random effects estimation is preferred to pooled OLS
estimation.
If we consider model 6, depicted in Table 5.3.6, fixed & random effects estimates of GDP variable
aren‟t significant with wrong sign whereas pooled OLS estimate of GDP variable is significant at 1%. Pooled
OLS, random effects & one way fixed effects estimates of PCGDP variable are significant at 5% with correct

(positive) sign. For model 6, fixed effects estimates (both one way & two way) of PCGDP variable are greater
than 1. So, it can be said that trade increases more than proportionally with an increase in the economic
development of the combined entity defined by the two countries. R2
of fixed effects estimation method is 0.80
(for both one way & two way fixed effects). F test for no fixed effects (both one way & two way) are significant
at 1% level.F test for the poolability of the model is rejected at 1% level & LM test statistic is significant at 1%
level.
Finally it should be noted that distance & common border variables are involved in the analyses as
traditional proxies for one of the impeding trade factor that is transportation costs. Converging distance cost to
transportation, has been criticized as exclusive since it leaves out other costs caused by distance such as risk of
damages or losses of the goods, time-related costs, communication cots, cultural distance etc. Despite there
critics, distance variable, as reported by Leamer & Levinsohn‟s (1994) survey on empirical evidence on
international trade, offers one of the most clearest & robust effects on explaining bilateral trade. The estimates
show that underlying gravity model works well. Geographic distance reduces trade, while greater economic
“mass” (real GDP and / or GDP per capita) expands it. The effects are economically & statistically significant.
Overall therefore the gravity model performs well for Bangladesh & both level of development „proxied‟ by per
capita GDP & distance play important roles in shaping Bangladesh‟s direction of trade. More specifically,
volume of trade responds to distance more than proportionally (β1 >1) . If country specific & time specific
heterogeneity both are considered, volume of trade always responds to level of development more than
proportionally (β3 >1).
As, β3 >1 , positive & significant, indicating Bangladesh trades more with richer countries than with
poorer countries (given Bangladesh‟s per capita GDP). A large per capita GDP promotes division of labor & this
means there is economies of scale in production & opportunities as well as desire to trade with greater variety of
goods. Bangladesh‟s direction of trade pattern is also strongly governed by geographical characteristics; such as
Area (always significant at 1% level for all models) implying Bangladesh has a tendency to trade with larger
countries. Given the strong under valuation of certain countries GDP, it is worthwhile to estimate the model with
GDP PPP.
Among the time invariant variables, sign of Cont dummy & its significance has clear interpretation.
Area variable is significant at 1% level with positive sign. Landlocked, Island, GSP, WTO2 & OECD1
dummies are dropped in fixed effects estimation, whereas, the procedure of including trading partners in the data
tells us to give more attention to the fixed effects estimation. So we run second stage regression, where results
(country specific fixed effects) of one way fixed effects estimation are regressed on time-invariant variables.
The regression results are reported in Table 5.3.7. The reason for using only the estimations from one way fixed
effects method is, all dummies like Cont, Landl, Island, Area are time invariant variables. For our data, GSP,
WTO2 & OECD1 dummies, are also time-invariant, as they do not vary over our sample period 1975-2005.
They only vary across country pairs.

VI. Trade potentials
Calculating trade potential is a line of research that has been used intensively with the gravity model
where the average speed of convergence is defined as the average growth rate of potential trade divided by
average growth rate of actual trade between the years of observations:
Average growth rate of potential trade
Average growth rate of actual trade × 100-100
…………(7)
Accordingly, we posit convergence if growth rate of potential trade is lower than that of actual trade &
the computed speed of convergence is negative. We have the divergence in the opposite case. The argument for
the prominent efficiency of this method over the point estimated method is that the speed of convergence
exploits the dynamic structure of the data during the estimation, which offers more reliable analysis than the
analysis of point estimates. The convergence measure is proved to be quite robust with different methodologies
such as pooled estimation, fixed effects & random effects in Jakab et al‟s (2001) paper.
In our paper, the residual of the estimated equation is interpreted as the difference between potential
and actual bilateral trade relations which is commonly known as in-sample projection approach (Egger 2002).
In estimating the trade potential between Bangladesh & her major fifty two trading partners, we use
residuals obtained from regression of equation 1 with Pooled OLS & estimate the speed of convergence for each
country using equation 7. The speed of convergence is calculated as ratio of average growth rate of potential
trade & growth rate of actual trade over thirty one years of study. In Table 6.1, we present the average speed of
convergence for the fifty two trading partners of Bangladesh.
Bangladesh‟s trade with her trading partners presents an interesting situation separating trade partners
into two groups, the first group characterized by an overtrade situation & the second one reflecting potentials to
develop trade. Bangladesh has convergence in trade with thirteen countries & divergence with other thirty nine
countries. In other words, Bangladesh has not exploited all the potentials in trading with her trading partners.
Trade between Bangladesh & her thirteen trading partners still has large room for growth.

Bangladesh has unexploited trade potential for thirteen trading partners of Bangladesh (countries which
have negative sign for the convergence measure) & has exploited trade potential for the rest thirty nine countries
(countries which have positive sign for the convergence measure). Bangladesh has unexploited trade potential
with Australia, Canada, China, France, Germany, India, Italy, Netherlands, Pakistan, Singapore, Switzerland,
UAE & UK. The amount of unexploited trade potentials are given in Table 6.2.

Is actual trade converging toward equilibrium ?
In order to be able to use the estimated level of trade as some kind of equilibrium level, we ascertain
that there is a tendency for actual trade to converge toward the estimated levels. For this purpose, we estimate a
simple error correction model by regressing the change in actual trade values on the difference between actual &
potential data in the previous period.
For convergence to occur, the estimated coefficient should be negative & significant. The estimation
results can be found in Table 6.3. The coefficients for the explanatory variable are negative & highly significant.
Hence, there is convergence of actual trade toward the estimated level in our sample, which is evident from the
following Table.

VII. Policy implications
The policy implications of the results obtained are that all kinds of trade barriers in countries involved,
especially in Bangladesh, must be liberalized to a great extent in order to enhance the Bangladesh‟s trade. There
remains considerable scope, for broad-based trade liberalization measures to spur trade between Bangladesh &
developed (industrial) countries, thereby increasing opportunities for technology transfers. Proper quality of the
goods & services must be maintained as well as the varieties of goods & services must be increased as the
Bangladesh‟s exports largely depend on foreign demand. The finding of untapped trade potential calls for
proactive export promotion policies, e.g. bilateral & multilateral agreements, trade facilitation etc. There are
some difficulties that exporters may face in exploiting the export destinations. These include among others, very
high import tariffs, lack of Bangladesh‟s diplomatic mission in the trading partner country, country not being a
member of WTO, lack of trade agreement with the country. There is therefore a need for the ministry of industry
& trade to work on these issues with a view to making it easy for members of Bangladeshi exporters association
to export. A number of authors have recently shown that political instability is partly the outcome of bad
economic performance & poverty. Political instability has a direct impact on trade flows. This is in line with the
literature on countries like Bangladesh which shows that improving economic governance fosters exports &
therefore growth. The results of this study indirectly suggests that Bangladesh has the potential of expanding its
trade & current account imbalances with Australia, Canada, China, France, Germany, Switzerland, UAE & UK.
Although these results may seem undesirable from the balance of payments perspective, they do give some

useful insights about the countries / regions with which Bangladesh can consider more integration through the
signing of bilateral & multilateral trade agreements. Most importantly, it is found that geographical distance has
significant impact on imports of Bangladesh which means transport cost & other transaction costs, such as the
probability of surviving intact of perishable goods etc still have significant impacts on its imports, as
Bangladesh mostly imports consumer goods rather than capital goods. An important outcome of the model & of
relevance to policymakers, is the significant influence of distance in trade. Projects which contribute to
decreasing of these costs should be placed high priority by the governments. At this point, reducing the distance
costs refers not to improvements of the physical infrastructure only, market access measures, border procedures,
movement of people, development & dissemination of information are important dimensions of the distance
costs that needs to the improved. Improvement in physical & technological infrastructures are especially
important for the development of trade. Economic growth of the individual economies will also strongly
influence both export & import potentials. Therefore stabilization policies & establishment of a conducive,
attractive business environment for private development which ensure high growth rates shall be high on the
agenda of policy makers. Although “money” doesn‟t seem to strongly affect trade in long term, we would
caution that due to different monetary policy regimes on Bangladesh attention shall be paid to exchange rate
management. The establishment of the FTA through the network of the bilateral free trade agreements might
offer new invention to fostering regional integration. FTA will potentially induce more trade creation while the
presence of “overtrade” with neighboring countries may also lead to some trade diversion. It is reasonable to
believe that an increase in trade intensity will not happen in all sectors. Increase in trade relations will be higher
in industries where the presence of multinationals is more significant & where economies of scale & technology
spillover effects prevail. Trade flows will tend to increase as income levels converge, demand structures get
more similar & international production networks expand. As a consequence, it is expected that significant
changes continue to occur in the comparative advantage patterns, which will depend on the countries position in
the labor division & on their competitive performance. Improving domestic policies may raise trade between
members of SAARC countries & hence contribute to regional spillovers. As, an increasing number of SAARC
countries engages in a process of economic reform & promotes openness & competition, more promising
outcomes in terms of intra-regional trade are to expected. All partner countries‟ propensities to export & import
must be taken into account sufficiently & adequately when trade policy is set as the Bangladesh‟s trade is not
independent of country specific effects. A more attractive business environment together with market
reorientation from government could help Bangladesh to overcome the slow down in trade with her trading
partners.
VIII. Conclusion
The main results indicate that the bilateral trade flows between Bangladesh & her fifty two trading
partners are driven by proxy for the stage of development or level of development (PCGDP), distance &
geographical characteristics like Area. According to the result of the gravity model, PCGDPS‟ of both the
exporter & importer countries have positive effects on the trade flows. This result agrees with the expectations
in theory. The more the incomes of these countries rise, the more rise in the demands of goods & service & in
the export & import potential would be experienced. Trade volume also responds to level of development more
than proportionally, implying Bangladesh trade more with richer countries than with poorer countries. The
distances between Bangladesh & the capital cities of trading partners of Bangladesh have a negative effect on
trade flows, since augmentation of distance among countries will extend the transportation time, the
transportation costs will increase. More specifically, trade volume responds to distance more than proportionally.
Bangladesh‟s direction of trade pattern is also strongly governed by geographical characteristics, such as Area,
implying Bangladesh has a tendency to trade with larger countries. Other geographical characteristics such as
Landlocked dummy has insignificant impact on trade but Island dummy has significant impact on trade. GSP
dummy variable has significant impact on trade. Membership in OECD countries has significant impact on
trade. Membership in WTO doesn‟t have significant impact on volume of trade. Fundamental rights, such as
civil rights has insignificant impact on trade implying higher freedom implies more trade with trading partners.
Although Bangladesh has exploited trade potentials with thirty nine countries, Bangladesh in general
has unrealized trade potentials with thirteen of her trading partners including Australia, Canada, China, France,
Germany, India, Italy, Netherlands, Pakistan, Singapore, Switzerland, UAE & UK. This finding is important for
policymakers because exploiting these trade potentials are expected to contribute to trade diversification for
Bangladesh. It is suggested that Bangladesh needs to sign bilateral trade agreement with each of these above
mentioned countries. Bilateral trade agreement such as the case of Bangladesh & China trade agreement would
increase trade substantially. Moreover, besides trading with large countries, increasing trade with small
economies which have trade potentials such as Singapore, UAE, Netherlands would also be of priority. We have
also tested whether actual trade converges toward potential trade & found the coefficient of convergence as
significant with correct sign. It should be noted that the period under consideration is a period when policies

played a very important role in shaping Bangladesh‟s trade. Indeed, throughout most of the period Bangladesh
followed a conservative trade regime. To the extent that the gravity model is policy neutral, the relative success
of the model is not entirely on the expected lines, Bangladesh‟s trade continued to be guided by natural forces to
a large extent throughout the independence of Bangladesh.
