Introduction
In 1979, Jimmy Carter was President of the United States, the Berlin Wall was intact as was
the Soviet Union, the Tokyo Round was not implemented and the Uruguay Round was a decade
away.
Between 1980 and 2000, about 125 free trade arrangements were negotiated and
implemented, the EU expanded twice and adopted a common currency, and there was a capital
market disruption in 1997 of historic proportions involving the former Soviet Union and many
countries of East Asia.1 Through all of this the world economy grew by more than 70% and world
trade grew by a remarkable 175%. Yet, in this paper we provide evidence that the pattern of
international trade for many countries appears to have remained relatively stable: principal trading
partners do not change, and trade shares exhibit remarkable constancy.
This trade pattern stability over a long period of time is not what economists usually predict.
For example, Yarbrough and Yarbrough (2000) echo the intuition of many economists when they
write in their popular textbook:
The evolution of comparative advantage over time implies that production and trade patterns
will change over time as well, creating changes in the distribution of income and some
difficult dilemmas for policymakers. These changes are evident even over a fairly short
period of time.
But, examination of the market for aggregate imports for almost 100 countries over the last two
decades of the twentieth century calls this fluidity of trade patterns into question.
Another way to think about the presumptions of the profession regarding trade pattern
stability is the skepticism that has often met evidence of very low price and income elasticities in
studies of trade behavior. Clearly, since 1980, relative prices have changed a lot and the terms of
trade of most countries have fluctuated considerably (see Table 1). Yet again, we will demonstrate
1

that trade shares have remained relatively constant. This would seem to support estimates of low
trade elasticities found in studies such as Warner and Kreinin (1983).
[insert Table 1 about here]
Furthermore, growth rates have varied substantially between countries, which should affect
trade shares (see Table 2). Similarly, technological progress has made the world a different place
and this should also impact trading patterns, especially to the extent that technology changes have
not been uniform across countries. Finally, ocean freight and port charges per short ton of cargo
have fallen 50% since 1945, air transport costs are down by even more, and communications costs
have essentially disappeared. These changes, one would think, might have an affect on trade
patterns, but the data are not so conclusive.
[insert Table 2 about here]
More specifically, in this paper we exploit a newly manageable data set from the IMF in
order to quantify the extent to which trade patterns have changed over the last two decades. The
trade data focus on bilateral trade patterns for 93 countries and are quite robust in cutting across
countries of diverse economic, political, and cultural traits during a fairly turbulent period of
economic history. In Section 2, we describe the data and develop some measures of trade pattern
change. We report evidence on the characteristics of countries that hold primary market shares in
national import markets and demonstrate that the shares of these countries and other principal
suppliers remain relatively constant over the sample period. Then, in Section 3, we present some
preliminary thoughts on what is going on and what this might portend for various theories of
international trade. Finally, Section 4 offers some conclusions.

Empirics
In this section, we present evidence on the stability of trade patterns for a large number of
countries over the past two decades. In developing this evidence, we use data from the International
Monetary Fund’s Direction of Trade Statistics March 2002 CD-ROM. This database provides
figures on the values of merchandise exports and imports by trade partners for 186 countries. In our
analysis, we focus on bilateral import totals valued in c.i.f. terms. The database reports these values
measured in U.S. dollars for all countries. Our study utilizes annual data from 92 countries and 1
territory (Hong Kong) over the period 1980-2000.2 The countries chosen for this study cover all
geographic regions of the world and employ most economic systems. We chose not to include data
from countries such as the states of the former Soviet Union that did not exist at the start of the
sample period or countries such as Kuwait and Sierra Leone, where there were breaks in economic
data because of wars or other disruptions. A complete list of countries included in our analysis can
be found in Appendix 1.
Our analysis focuses on the behavior of the nominal market shares of the countries that
supply goods to the countries in our sample. We measured these as the ratio of nominal imports to
total imports (as reported in the database) times 100. Because of the large number of countries in
the database, we present details for only those countries that enjoyed at least 2 percent of a given
country’s market in 1980. Even with this limitation, we ended up with 926 bilateral trade patterns
to analyze, or roughly ten trading partners for each country in the sample.

Bilateral trade: Primary trade partners
Using this market share data, we focus on a variety of questions related to bilateral trade

patterns. The first issue we consider is related to primary trade partners. To clarify the points we
would like to make, consider Figure 1. This provides a graph of the import market shares for
Tunisia over the sample period. The behavior in this graph typifies most of the patterns we found
in our sample.
[Insert Figure 1 about here]
In particular, throughout the sample period, one country (here France) held the largest share
of the market. Its market share averaged about 25 percent. For more than two thirds (66 of 93) of
the 93 countries in our sample, the same country had the greatest market share at both the start and
the end of the sample period. In addition, the average market share of the primary trade partner was
27 percent in 1980 and 26 percent in 2000.
The fact that France held the largest share of Tunisia’s import market is readily explained.
France is a high income, industrialized country located near Tunisia. Perhaps most important, it
governed a colonial protectorate in the country for more than 60 years, and, as a result, French is an
official language of the country. As it turns out, attributes such as proximity, former colonial
relationships, and being the geographically nearest high income industrialized country appear to be
extremely important in explaining market share dominance.3 This is confirmed in Table 3 where
we show that these characteristics are found in more than two thirds of the primary market share
holders in our sample.
[Insert Tables 3 & 4 about here]
Table 4 summarizes how often various countries held leading market shares at the start and

end of the sample period.4 As Table 4 demonstrates, a small number of high-income countries,
including the United States, France, Germany, Japan, and the United Kingdom were most likely to
hold the dominant share of a country’s market at both the start and end of the period. Moreover, as
is exemplified in Figure 1, high-income countries tend to maintain market shares in every country
in our sample. This, of course, is consistent with the fact that these countries consistently lead world
rankings as major exporters in value terms. What may be surprising is the global universality of
their market penetration, and the relative stability of this penetration over time.5 We turn now to the
question of market share stability.
2.2
Bilateral trade: Market share stability
Figures 2-5 provide graphs of the evolution of these market shares for Austria, France,
Pakistan, and Uruguay. As the figures indicate there are remarkable differences in these patterns
from one country to the next. Nonetheless, it is clear that the shares in Figures 2 and 3 exhibit
considerably more stability than those in Figures 4 and 5.
[insert Figures 2-5 about here]
To our knowledge, no previous work has compared the behavior of market shares over time
for a large set of countries.6 We do not have strong priors as to what patterns one should expect to
find in these shares. Nonetheless, as we noted in the introduction, given all of the changes
experienced in the world economy over the past two decades we would not have found it unusual
to observe considerable instability in trade patterns and partners. In the remainder of this section,

More complete detail on the characteristics of dominant trade partners for the countries in our sample can be found
in Appendix 2.

As will be discussed below, an exception is Japan which has lost market share in a number of markets, especially in
the 1990s.

Wall (2002) examines trade share behavior for Japanese exports to various markets between 1986 and 1997.
5
we will try to make the case that stability, rather than variation, in trade shares is a strong and
recurring phenomenon.
There is no good metric to quantify the behavior we are trying to study. Consequently, we
have chosen a simple procedure to make our first pass at the data. In particular, we regressed each
series of trade shares on a constant and a time trend. As the plots in Figures 2-5 indicate, simple
linear models should approximate well the behavior of many share patterns, and we found that to
be the case throughout. Our purpose in this exercise was to determine how often we would find that
the shares were trendless. Our first thought in approaching this question was to see how often we
could reject the null hypothesis that the coefficient on the time trend was zero. We also considered
testing the joint hypothesis that all of the time trend coefficients were zero. In examining the output
from our statistical work, however, it became clear that this would not work well in our context. In
particular, if shares were virtually constant, the t statistic on the estimated trend would approach
infinity, even as the estimated slope is near zero. Indeed, we found numerous examples of trend
coefficient estimates with values almost identically zero, but with t statistics much larger than two.
7
This same problem also confounded our ability to test the joint hypothesis that all of the slopes for
a given country were zero.8 Given these problems with standard hypothesis test procedures, the
remainder of this section is devoted to distributions of point estimates.
[insert Table 5 about here]
Table 5 provides detail on the point estimates from the regression exercise. In order to better
interpret the results we multiplied each of the estimates by 21 in order to determine the estimated
change over the sample period in each of the trade shares. As the table shows, the predicted change

Only 272 of 926 estimated slope coefficients had t values small enough to not reject the null that the slope equaled
zero.
8
We rejected the null that all slopes equaled zero in every case.
6
did not exceed 2 percent in absolute value for almost half (449 of 927) of the possible trade patterns.
As the table also shows, falls in shares were estimated for well over half the cases. The median
projected decline in market share over the sample period was 1.69 percent. In more than 15 percent
of the cases, estimates of trade share falls exceeded 5 percent over the sample period. Many, if not
all, of the largest declines were associated with trade shares for petroleum exporting countries. This
pattern is easy to explain and points to a problem with the fact that data availability required us to
begin our analysis in 1980. That year coincided with the second world oil shock. In subsequent
years, oil prices (and probably oil consumption) fell dramatically leading to significant falls in
market shares. These declines are apparent in Figures 2-5.
As was the case with primary trade partners, a small number of high income countries held
market shares of at least two percent for virtually all countries in the sample over the sample period.
And, as with the case of all shares, the shares of these countries were relatively stable. These points
are illustrated by the information in Table 6.
[insert Table 6 about here]
As the table shows, the United States held at least 2 percent of the market in 88 of 92
possible cases. Both the median and the mean of the projected market share change over the sample
period were between zero and a fall of one percent. Germany, the United Kingdom, and Japan also
held at least two percent of the markets in 80 countries or more. Only the mean and median
projected change in market shares for Japan exceeded 2 percent in absolute value. France, Italy, and
the Netherlands all held significant market shares in more than half of the sample countries, and the
average expected market share changes for all were less than one percent. Only Saudi Arabia, which
held at least two percent of the market in 30 countries in 1980 had large (greater than five percent)
7
average projected changes in market share. As noted already, this pattern held true for virtually all
oil exporters in virtually all countries.
The major point of this section is that trade shares have remained quite stable for most
countries over the past two decades, despite significant changes in the economic and political
structure of the world trading relationships. There is clearly more work to be done in this analysis
and we are beginning these efforts. Our first goal is to derive a metric that allows us to compute and
then try to explain how much and why trade patterns have changed on a country-by-country basis.
Our plan is to try to develop a test to see if the annual trade shares we observe for a country look to
be draws from a common distribution. It is possible to develop a statistic that represents the average
distance between each of the draws and to use this statistic in subsequent tests of possible models
that predict relative stability in trade patterns. Since we are not ready at this time to present these
tests, in what follows we discuss several conjectures from trade theory that might explain the
stability that we have found in the data.
3.
Theory and Speculation
Three themes seem to recur in our data. First, country size seems to matter and, in particular,
trade shares of most nations with the United States and most other high income countries are
especially stable. Second, distance matters. Countries have very stable trade shares with their
immediate neighbors. Finally, historical ties seem to matter in the sense that trade shares between
former colonies and the mother-country are quite stable.
A curiosity of the data is that while trade shares remain fairly stable, the composition of trade
changes quite a bit. For example, in 1979, office machines, computers, parts (SITC 751, 753, 759),
constituted only 1.4% of the share of trade and was ranked 16th by category. In 1999, this group was
8
6% of trade and ranked number one as the most traded commodity group.9 Yet, nations do not
appear to be acquiring market share at the expense of other nations. This change in the pattern of
trade seems to generalize. That is, the commodity composition of trade changes, but the trade shares
between countries do not. This raises some questions that we address here, but offer only speculation
as answers.
Specifically, there seems to be a sort of “hysteresis” in the pattern of trade. The world
changes a lot in terms of prices, technology, and so on, but trading partners and trade shares remain
constant. This “evidence” speaks in favor of some trade theories as being more or less important.
3.1
Standard static trade theories
The constancy of bilateral trade shares over time can inform us about the robustness of
various trade theories. For example, the standard, variable-proportions – Heckscher-Ohlin – model
predicts that, if tastes are identical and homothetic, then differential (balanced) growth rates among
trading partners will lead to changing trade shares (see Appendix 3). Yet, while growth rates do vary
quite a lot between countries (recall Table 2.), trade shares are relatively constant. While this hardly
constitutes a test of the H-O model, it is suggestive that one of the model’s predictions is
questionable. Since technological progress is analytically similar to growth, differential rates of
technical progress across countries should similarly lead to changing bilateral trade shares.
Such results, we think, would apply equally to a specific factors model and, in light of the
Jones-McKenzie Theorem, to a Ricardian model with many goods and countries. (Specifically, in
the multi-good Ricardian model, the conditions for country j to specialize in good j – “j-j
specialization” – depend upon a comparison of a multiplicative string of one set of labor-output
9
See Table 1.3 in Steven Husted and Michael Melvin, International Economics, 6th edition, (Addison Wesley
Longman, Boston) 2003.
9
coefficients with another such string. But, differential technical progress – some lower labor-output
coefficients for some countries -- will change the pattern of specialization and so necessarily the
share patterns in trade.) Yet, economic change in the world does not appear to lead to changes in
bilateral trade shares.
Finally, the wave of new preferential trade agreements (PTAs) and new accessions to old
PTAs since 1979 should entail trade creation and trade diversion. Thus, bilateral trade shares should
be affected. Here we find mixed experience regarding trade shares in our data. For instance,
Mexico’s share of North American trade has grown rapidly since the formation of NAFTA, but trade
shares of EU countries in Austria have remained virtually constant since Austria’s entrance into the
EU in 1995.
3.2
Geography and trade
One recently advanced view of the world that is consistent with our findings is the
“economic geography” paradigm, long around, of course, but most familiar to trade economists
through Paul Krugman’s Gaston Eyskens lectures at the Catholic University of Leuven in Belgium.
That paradigm renders country size, proximity, and cultural ties -- which do not change so rapidly -crucial to the bilateral shares of trade, but not to the commodity composition of bilateral trade. This
seems consistent with our findings.
First, the economic geography model focuses on transport networks and scale economies.
Firms and industries cluster geographically, and this creates persistent production nodes even as the
product lines shift. Transport networks get put into place and, once the costs are sunk, can
determine which countries trade with which other countries. For example, if there are three
10
countries in the world – A, B, and C – and there are railroads between A-B and B-C, but not A-C,
then trade shares might remain fairly constant to the extent that transport costs are important.
This implication of economic geography models is consistent with our finding that distance
is an important determinant of why trade shares remain constant between trading partners of the
world. Also, if “distance” is taken to include cultural distance, our findings corroborate a stability
in the trade between former colonies and their colonial mother-countries.
Finally, the trade shares of large countries, including France, Germany, Japan, the United
Kingdom, and the United States, seem to remain particularly constant. This is consistent with
Krugman (1991). Large countries (regions) exploit scale economies and transport systems in order
to maintain an industrial base even as the products themselves change. Thus, for example, the
industrial belt of the Midwest in the United States continued to prosper even as the product line
changed over time. Consequently, the region was the stable exporter of industrial products for a
very long time, even though the products themselves were changing. This is roughly consistent with
our findings of constant bilateral trade flows.
4.
Conclusions
The world would appear to have changed in most dimensions quite a lot since 1979.
Certainly the economic and political landscapes are wildly different. Yet, when we measure which
countries trade with which other countries the world looks remarkably constant. We cannot find
much change in bilateral trade shares among countries. This finding is all the more striking because
the commodity composition of trade does appear to change.
While our approach has been simply to report the stability of bilateral trade, we also
conjecture that the data support the “economic geography” paradigm wherein distance, history, and
11
country size are important determinants of international trade patterns
