Summary findings
Exporters' performance in a particular market may affect
their future exports to the rest of the world. Importers
may base their future transaction decisions on the
information revealed by exporters' past performance in
other countries. Similarly, exporters acquire valuable
information on foreign consumer tastes, product
standards, or customs administration that may profitably
be used in future transactions with other countries.
Nicita and Olarreaga estimate the effects of these
information spillovers across markets on the export
patterns of four developing countries (Egypt, the
Republic of Korea, Malaysia, and Tunisia). A dollar
increase in exports to the United States generates on
average an extra 2 to 14 cents of exports to the rest of
the world in the next period.
Social and ethnic networks seem to reinforce these
information spillovers, especially in developing countries,
where they appear to be geographically more
concentrated. The exception is China and to some extent
Hong Kong, probably reflecting a geographically more
diversified migration pattern.
The exchange of information among current and
potential export markets can significantly affect a
developing country's export performance. Bilateral
information spillovers across markets are negligible or
nonexistent for exports from the United States, where
there is less need to create a reputation in international
markets. Similarly, Egypt's good export performance
would be more easily noticed in Argentina or India
(where the market is small) than would increased exports
to France or the United States.

Non-technical summary
There is little doubt that in any type of business, individual relationships
among trading partners are extremely valuable and can determine the success
or decline of a firm. The information acquired through each interaction is seen,
by both buyers and sellers, as an investment, which will bring future benefits.
The need for information among business partners is probably more
pronounced in the case of international transactions. The export success of a
firm (and ultimately a country) will depend on the quality of its business
relationships. Through repeated interactions, both exporters and importers will
acquire valuable information on reliability in terms of the credit and delivery
of their trading partners.
The information created by the business relationship may spill over to other
exporters and importers. These information spillovers may not necessarily be
limited to national borders. Importers' direct experience with an exporter may
generate valuable information that can be used as an important guide in
deciding future transactions with other countries. This implies that a good
export performance in one market will not only have positive effects in the
same market in the future, but may also positively affect export performance in
"'neighboring" markets through information spillovers. Similarly, exporters
may acquire valuable information regarding the functioning of customs
administrations or foreign consumer tastes, which could profitably be used in
future transactions with other countries.
This paper focuses on the importance of these international information
spillovers on the export performance of four developing countries, which have
experienced varied export performance in the last decade: Egypt, Korea,
Malaysia and Tunisia. Using the United States as an example of a market
where information is generated, we found that an extra dollar exported to the
United States by Korea generates on average an increase in Korean exports to
I
the rest of the world of 14 cents. A similar figure for Malaysia is 10 cents,
whereas in Egypt and Tunisia, the figure is close to 2 cents. We also found that
some developing countries' export markets, such as India and Argentina,
generate larger increases in exports to the rest of the world through information
spillovers. Spillovers tend, however, to be geographically more concentrated,
in the sense that most of the additional exports occur within a few
geographically close countries.
The exception in developing countries in terms of geographic concentration as
a source of information spillovers to the rest of the world is China and to some
extent Hong Kong, where infornation spills over to geographically diversified
countries. This is probably due to the less geographically-concentrated
migration pattern of China and Hong Kong.
These results suggest an important role for public or private export information
agencies in developing countries. Diffusion of export information across firms
can significantly contribute to the export performance of a country. The
analysis also detected the presence of externalities at the two-digit industry
level, which suggests that there is room for co-operation through bundling of
export offers across firms in the same two-digit industry. The presence of these
information spillovers also implies that one bad deal or poor performance in
one market not only hurts exporters in that particular market, but may also hurt
them in other markets. This suggests an important role for quality controls,
such as ISO standards, that can be publicly or privately organized.

considerable export experience and require little instruction and assistance.

Introduction
There is little doubt that in any type of business, individual relationships among trading
partners are extremely valuable and can determine the success or decline of a firm.
Through repeated business transactions, a certain degree of trust is developed between
sellers and buyers, which reinforces the relationship. Future transactions become more
profitable through a better understanding and knowledge of each others' needs. The
information acquired through each interaction is seen, by both buyers and sellers, as an
investment which will bring future benefits.I
The need to create bilateral information among business partners is probably more
pronounced in the case of international transactions. The export success of a firm (and
ultimately a country) will depend on the quality of its business relationships.2 Through
repeated interactions, both exporters and importers will acquire valuable information on
reliability in terms of the credit and delivery of their trading partners. It will also provide
knowledge of the functioning of custom administrations, foreign market tastes, product
quality, standards, certification and design (Egan and Mody, 1992, Evenson and Westphal,
1995, Grossman and Helpman 1991, Rhee, Ross-Larson and Pursell, 1984 and World
Bank, 1997).3
For a potential exporter to successfully enter an export market, it needs to build a
reputation as a reliable supplier and learn about market tastes and structures. The process
'Repeated interactionalso solvesthe problemof asymmetricinformationas shownby Riordan(1986).
2 As reportedin a studydone by Egan andMody (1992)basedon a surveyof US importers,one bad
shipmentcan leadto a completebreakof a businessrelationwith low reputationsuppliers.

of building a reputation may be costly. However, reputation building may also show some
multiplier effects, as the individual relationship established between an exporter and an
importer will typically generate information spillovers beyond the two trading partners.
Importers may use other importers, who have had direct experience with potential
suppliers, as a source of information on the performance of alternative exporters (World
Bank, 1989). This effect may be reinforced by information spillover effects on the exporter
side, as export activities generate a better understanding of how foreign markets work. This
is valuable information for future transactions. Also, the export success of a firm in some
markets may generate demonstration effects for other firms, which become aware of
potential opportunities in foreign markets. Export promotion or industry agencies, both
public and private, may also help diffuse this information across firms.
Information spillovers may not necessarily be limited to national borders. Importers who
have had direct experience with an exporter may generate valuable information that can be
used as an important guide in deciding future transactions in other countries. This implies
that a good export performance in one market will not only have positive reputation effects
in the same market in the future, but may also positively affect export performance in
"neighboring" markets through information spillovers. Similarly, exporters acquire
valuable information regarding the functioning of customs administrations, foreign
consumer tastes, shipping procedures, and distribution networks, which could profitably be
used in future transactions with other countries.4
Social or ethnic networks may help the international transmission of these information
spillovers in various ways: helping to match buyers and sellers across borders; creating
market similarities; easing the transmission of these flows across borders; and serving as a
deterrent for opportunistic behavior, as in Rauch (1999) or Rauch and Trindade (1999).
Even in countries with well-developed judiciary systems, an important share of what
makes a successful business deal will typically lie outside the contract established by
An alternative explanation for the observation of this export reputation spillovers across borders is the
existence of production networks, where plants of the sarne network are located in different countries.
Initiating business with one plant in the network allows much easier access to other buyers within the
network (see Kaminski and Ng, 1999).

trading partners (McLaren, 1999). Trust provided by ethnic networks therefore has an
important business value. As the empirical section will reveal, the importance of these
ethnic networks in explaining the export performance of developing countries is indirectly
confirmed in our study. Information flows among countries will be facilitated by the
presence of these ethnic networks.
The objective of this paper is to try to identify the importance of these international
information spillovers to the export performance of four developing countries which have
experienced varied export performance in the last decade: Egypt, Korea, Malaysia and
Tunisia. The choice of countries is deliberate in the sense that we wanted to have a set of
developing countries from different regions and at different stages of development.5
The questions we will be asking are, for example: Does the export performance of Egypt in
France affect exports from Egypt to countries which share large information flows with
France?; and if so: How important is Egypt's export performance in France in explaining
Egypt's export performance in the rest of the world?
In the empirical section we found that information spillovers had important effects in the
export performance of these four developing countries. Interestingly enough, we also
found that information spillovers have little effect on the export pattern of the US. This
suggests that the role of information spillovers is more important in developing countries,
where the need for building a reputation in international markets is larger.
Taking the United States as an example of a market where information is generated, an
extra dollar exported to the United States by Korea generates on average an increase in
Korean exports to the rest of the world of 14 cents. A similar figure for Malaysia is 10
cents, whereas in Egypt and Tunisia the figure is close to 2 cents. We also found that some
developing countries' export markets, such as India and Argentina, generate larger
increases in exports to the rest of the world through information spillovers. They tend,

however, to be geographically more concentrated, which is probably due to their less
diversified migration pattern.
The rest of the paper is structured as follows. In section 2, we discuss the importance of
information flows across countries and the different measures used in this paper to capture
bilateral information flows. Section 3 develops a simple model with export information
spillovers across nations. Section 4 focuses on the econometric model, and section 5
reports the results for the four developing countries in our sample. Section 6 quantifies the
importance of export information spillovers for the export performance of these four
developing countries. Section 7 outlines the conclusions.

Information Flows across countries
Related literature has suggested several ways to capture information flows. First, Rauch
(1999) suggests that geographic proximity facilitates the exchange of trade related
information. The rationale for this is twofold. First, communication costs might affect the
flow of information, second, information from other buyers may be more valuable the
closer these other buyers are from the domestic market in terms of tastes, product-designs
and other cultural factors.6 Thus, information flows would follow a distance decay function
and would be larger among relatively close countries.
Rauch and Trindade (1999) suggest the use of the share of common ethnic population to
capture information flows. The idea is that ethnic networks facilitate the exchange of
information. The larger the share is of Chinese population in two countries, for example,
the larger the information flow between these two partners.
6
SeeRhee,Ross-LarsonandPursell(1984)or Evensonand Westphal(1995).
6
Two other proxies are suggested by Portes and Rey (1999). These authors measure
information flows using bilateral telephone calls and bilateral trade.7 For telephone calls,
the intuition is straightforward; whereas for bilateral trade the idea is as discussed above,
that business relationships are subject to the exchange of information.
Rauch and Trindade (2000) suggest the use of the number of periodicals and newsletters
devoted to international trade and commerce as proxy for trade related information.
Because we are interested in bilateral information flows, we propose the use of bilateral
trade in periodicals and newspapers as proxy for trade-related information flows (SITC rev
1. 8922). The exchange of newspapers will not only include directly trade related
information, as in the case of the Journal of Commerce or Export Channel in the US, Made
for Export in Europe, Asian Channel in Hong Kong, and Gazeta Mercantil in Latin
America. It will also reflect cultural similarities and bilateral immigration patterns, which
will also be important determinants of "indirectly" trade related information flows, such as
taste similarities across countries.
All of these proxies have advantages and disadvantages when it comes to their empirical
application. In the empirical section we will test each of them, except the bilateral share of
ethnic population between partners. The reason for the exclusion is that we would need a
matrix of bilateral migration patterns in the world which is, to our knowledge, unavailable
(see Zlotnik (1998) for a discussion of data availability for international migration).8
However, Rauch (1999) has argued that distance may be correlated with the existence of
these ethnic networks. We believe that bilateral telephone calls and newspaper trade also
capture their presence. However, we will argue that bilateral newspaper trade is the more
adequate proxy to capture information flows across countries. Results reported in section 5
are estimated using newspaper trade; but other proxies provided robust results.
See footnote 16 in Portes and Rey (1999) for the use of aggregate bilateral trade as a proxy for information
flows between countries.
8 Rauch and Trindade (1999) focus on the effects of Chinese networks on bilateral trade relations in the
world and therefore had smaller data requirements.

There are at least two reasonswhy distancemay be an imperfectproxy: it fails to capture
size and culturalor historical effects.To illustratethe importanceof size effects,note that
using distanceas a proxy would imply that the exchangeof informationbetweenArgentina
and Uruguaywould be largerthan betweenArgentinaand Mexico.However,the exchange
of information measured by newspaper trade (for example) suggests that the exchange
between Argentinaand Mexicowas more than ten times larger in 1995due simply to the
relative size of their markets (see Table 1). Regardingthe failure of distance to capture
cultural and historicallinks, note that its use would imply that the exchangeof information
between Australia and the United Kingdom would be smaller than the exchange of
information between China and Australia, since the latter are geographically closer.
However,cultural factors such as languageand coloniallinks imply that newspapertrade
between Australia and the United Kingdomwas 200 times larger than between Australia
and China in 1995.
Bilateralaggregatetrade may solve some of the problemsassociatedwith distance,as size
and culturallinks are importantdeterminantsof trade. However,bilateralaggregatetrade is
also determinedby many other factors,such as comparativeadvantage,and may therefore
be poorlycorrelatedwith bilateralinformationflows.9 More importantly,these information
flows may be crucial for an exporter in a third country, who may be able to build a
valuablereputationin one of the two markets,and may benefit from the informationflows
between the two countriesto increase its export performancein the other market. As an
example, Ireland's newspapers trade with the United Kingdom represented almost 98
percent of its total trade in newspaperin 1995,whereasthe share of the United Kingdomin
Ireland's total trade is close to 30 percent. Similarly,20 percent of Kuwait's newspaper
trade is done with Egypt;but Egypt only represents1.5 percentof Kuwait's total trade.
Bilateraltelephone calls may also solve the problemsdescribedabove associated with the
use of distance or bilateral trade as a proxy for informationflows across countries. But it
may raise other problems, when trying to capture informationflows among developing
8
countries. First, the data that is available today at the International Telecommunications
Union does not cover a wide range of developing countries (of the 60 countries considered
as potential export markets in our sample, 41 are developing countries), and its time
dimension is limited (there is no data available before 1985). Second, telephone calls may
be a very expensive means of exchanging information for developing countries due to the
high cost of international calls. Newspapers are probably the cheapest way to widely
disseminate information.1 0
2.1
How largeare bilateralnewspaperflows?
The value of world newspaper exports was close to 4 billion dollars in 1995, and
represented 0.1 percent of world exports. The growth of bilateral newspaper trade during
the period 1969-1997 is close to 10 percent in nominal terms per year. Germany is the
world's largest trader of newspapers with a total trade (exports plus imports) of 1.2 billion
dollars in 1995. It is closely followed by the United States, which was involved in 25
percent of world newspaper trade in the same year (as either an importer or an exporter).
These flows can also be relatively important in developing countries. Brazil's total trade of
newspapers was close to 87 million dollars in 1995. The total value of newspaper trade
between Brazil and Chile was 30 million dollars, whereas between Singapore and Malaysia
it was close to 10 million dollars. Table 1 below provides the share of bilateral newspaper
trade and total newspaper trade for a selected number of countries.

Export Information Spillovers across countries
Export information spillovers are defined as the set of information flows that are generated
in a particular export market and that will affect export and import decisions between the
original exporter and importers in the rest of the world. They are illustrated in Figure 1.
9 To seethis, acceptforthe momentthat trade flowsare exclusivelydeterminedby factorendowments.Two
countrieswith identicalfactorendowmentswillnot trade with eachother,but mayhave a significant
exchangeof information.

The exporter's performance in country k generates information spillovers (the dashed
lines) into two locations. First, it gives feedback to the original exporter on information
about customs procedures, product standards, and tastes in foreign markets, which may
help in the next period its export performance in a third market: country c. Second,
importers in country c learn about the reliability and product quality of the original
exporter by observing the exporter's behavior in the rest of the world. This will affect
import decisions in the next period.
The size of export information spillovers between countries k and c will therefore depend
not only on the export performance of the exporter in country k, but also on the extent of
information exchange between country c and country k.
3.1
A simple model
Firms face constant marginal costs in country 0 (the exporter). Marginal transport costs are
also constant. Thus, total cost of exporting from country 0 to country c at period t, denoted
CC t, is
given by:
C", = [a +, Tdc ]xc,(1
where a is the marginal cost of producing the export good; r, is the marginal transport
cost; d, is the distance from country 0 to country c; and xc, are exports from country 0 to
country c.
Export markets for exports originating in country 0 are segmented, which combined with
the assumption of constant marginal costs of production allows us to deal independently
with each export market.

Demand for each product in each market is derived from a quasi-linear and additive utility
function, which freezes substitution and income effects in demand. Each sub-utility
function is quadratic so that demand functions are linear. Units are chosen so that the slope
of the linear demand function equals 1.
There are information spillover effects, in the sense that demand today for exports of
country 0 depend on the market share of country 0 in the previous period. The larger the
market share of country 0 in period t is, the larger the demand it will face in period t+] .II
Information about past export performance also spills over from other countries as
suggested in Figure 1. The exporter's past market shares in rest of the world markets also
affects the level of demand for its products in country c. Thus, information spillovers are
here modeled on the demand side, but could be similarly introduced on the supply side. In
our empirical section, we will not be able to disentangle between demand and supply
spillovers, and therefore our estimates will be a mixture of both. Inverse demand for
exports of country 0 to country c at period t is therefore given by:

p,,, =a -XCI +A SC,1-I+ 1,1-S,

the share of each rest of the world country in country c's total information flows with the
world;'2 S,, is a vector of market shares of country 0 in each market. Thus, 9 > 0 captures
the export-market information spillovers across markets.
'" See Frootand Klemperer(1989)or Farrell(1986)for a discussionof the relevanceof past marketshares in
determiningfuture demand.
12 We use sharesinsteadof actual flowsfor severalreasons.First,it makes interpretationeasier. Second,if
the proxy used for informationflowshas a time dimension,then it will avoid our havingto deal with the

Equation (4) implies that an increase in export performance in any location will affect
exports to all other countries in the next period through information spillovers.

Econometric model and data
We will try to capture information spillovers at the product line level and therefore we will
use bilateral trade data (60 countries) at the 3-digit of the SITC classification for
manufacturing products. For each of the exporting countries in our sample, we will then
use the whole sample of potential export products to all countries where a product has been
exported at least once during the period 1969-1997. Trade data sources are from national
sources compiled by the United Nations in Comtrade's data base.
Information flows are captured using the four proxies described in section 2. In the case of
distance, we use the matrix of inverse bilateral distance between countries. For total trade,
we use the share of bilateral trade with each rest-of-the-world country in the importer's
(country c) aggregate trade with the rest of the world. For international phone calls, we use
the share of international phone call minutes between country c and each of the rest-of-theworld countries. Finally, newspaper trade is calculated as the share of bilateral newspaper
statisticteststhatwe useto testtheerrortermforpotentialcorrelationacrosscountriescruciallydependson
the standardizationof this matrix(seeFloraxand Folner, 1992or Anselin,1999).
12
trade with each rest-of-the-world country in country c's total newspaper trade with the rest
of the world. When using newspaper trade and total trade, the proxy for information flows
contains a time dimension, as data is available throughout the period. However, the data on
telephone calls had very little time dimension before 1992 and no data before 1985.
Therefore we took the year 1992 as the base year and used the number of bilateral minutes
of phone calls for 1992 values, or the closest year (1991 or 1993) for which there is data
available, as a proxy for information flows.'3 In the case of distance, there is obviously no
time dimension either.'4 More detailed information on variable construction can be found
in the Data Appendix. Results reported in section 5 are obtained using newspaper trade as
a proxy for information flows. Other proxies yielded robust estimates, though newspaper
trade generally yielded more efficient results.
We will base the empirical analysis on a stochastic version of equation (4) and test for
information spillovers by testing the significance of the paramneter0 . The non-existence of
exports in many products across trading partners leads to a large presence of zeroes in our
endogenous variables (89 percent of censoring in the case of Egyptian exports, 40 percent
for Korea, 60 percent for Malaysia and 91 percent for Tunisia).
To correct for the bias introduced by censoring, we estimate equation (4) for each of the
four exporting countries (Egypt, Korea, Malaysia and Tunisia) using a tobit technique: 15

Xp,c = °if

+6p,c
13 Note that due to the lack of data available at the Intemational Telecommunication Union on minutes of
bilateral phone calls our estimation for bilateral phone calls only include 41 of the 60 countries in our sample.
However, as suggested before, the results were consistent with what we report in section 5 using newspaper
trade as a proxy.
14 Note that to avoid identification problems, we need the elements of the information flow vector to be
exogenous. Note that this is the case for all proxies. For example, exports of Egypt to France in period t
cannot determine the information flows between France and Germany at period t-1.
'5 We alternatively used a two-stage tobit technique as in Maddala (1983, p. 221-222) and a two-part model,
which yielded similar results to the ones reported in section 5. Generally, results were more efficient when
13
where xpc r are exports of Korea (for example) of product p, to country c in period t; and
.
p c is the error term. In Anselin (1999) terminology this specification is an implicit pure
time-space recursive model. In this paper, the presence of information flows across
countries lead to a space recursive model, in the sense that the export performance in
country k will affect the export performance in all other countries in our sample through
information flows. It is implicit time recursive because the spatial lag of the endogenous
variables is expressed in terms of market share and not levels of exports, which allows us
to avoid problems related to lagged spatial endogenous variables. The lack of simultaneity
in the spatial correlation allows us, in principle, to abstract from problems of correlation
between the spatially lagged variable (ICSp,,l) and the error term. However, we will test
for error spatial correlation in the next section.
One may be tempted to add fixed country or product effects into equation (5), but as
suggested by Anselin (1999), this would lead to inconsistent estimates, in which case a
random effect specification should then be considered. Assuming country-specific
unobserved effects,16 the error term becomes:
wC, +
where wc, is
independently and identically distributed (i.i.d.) across countries and time, and 1p c, is i.i.d
across products, countries and time.
The estimation of information spillovers (0) through equation (5) may be biased by the
absence of some other important variables related to comparative advantage aspects or
other types of externalities that are absent in (5). To control for these, we add four
variables to the right hand side of (5).
using either the simple tobit or the two-stage tobit technique, which may be due to the structure of the data,
as discussed in Leung and Yu (1996).
16 In the empirical section we also considered a product-specific component for the error term and obtained
similar results to the ones reported in section 5.
14
First, size may matter. The larger the import market, the larger are exports to this market.
To control for the size of the import market, we introduce size, which is defined as total
imports of productp in country c at period t (purged of exports to country c).
Second, comparative advantage aspects may also affect our measure of information
spillovers. In some products the exporter may be a "natural exporter" and in others not. To
control for this we introduce ca, which is defined as total exports to the rest of the world,
denoted ca (again purged). It could also be interpreted as capturing "learning by doing" or
economies of scale in export activities, which would not be related to export informnation
spillovers across markets.17
Third, bilateral trade preference and cultural links may also affect our estimates. To
capture this, we introduce gravity, which is total exports of the source country to country
c (again purged). Gravity can also be interpreted as capturing all the explanatory variables
of a gravity equation for the export country (including cultural links, language, regional
trade agreements, etc.). It may also be seen as across product extemalities within the own
market.

A time dummy is also introduced in all estimations. All parameters are positive and
therefore expected signs are given by the signs in front of the parameters. Results reported
in the next section also correct for heteroscedasticity using Huber correction method. The
reported R2 is calculated following Veall and Zimnermnann (1994). As shown in their
study, the more traditional McFadden (1973) R2 has a downwards bias in large samples
with a high degree of censoring.'9

Empirical Results
We estimated equations (5) and (6) for each of four countries in our sample. Table 2
reports results of these estimations in the first and second column for each country (we
discuss results reported in the third column later). All variables have the expected sign and
are statistically significant at the 10 percent level or less, except for within two-digit
industry externalities in the case of Tunisia.20 Note that the introduction of the four control
variables in the estimation of equation (6) does not change the significance of the estimates
of equation (5).
We further test for the statistical significance of the information spillovers by performing
an F-test on the residuals of the estimation of equations (5) and (6) for each of the
exporting countries, as suggested by Florax and Folmer (1992) in the presence of spatially
lagged variables.21 All F-tests rejected the null hypothesis of absence of information
spillovers at the 1 percent level. We also found no evidence of spatial autocorrelation in the
residuals of the regressions of equation (6) reported in the second columns of Table 2. As

We also try to capture bilateral information spillovers within two-digit industries by weighting the twodigit industry variable by bilateral information flows, but results were insignificant for all countries except
Egypt.

suggested by Anselin and Hudak (1992) we performed a Lagrange Multiplier test that
corrected for the panel aspect of our data (product-year observations). We could not reject
the null hypothesis of no spatial autocorrelation.22
These results suggest that exports from any of the four countries in our sample (Egypt,
Korea, Malaysia and Tunisia) to a particular market will be affected by past export
performance in the rest of the world, through bilateral information spillovers between the
particular export market and rest of the world countries.
The rise of globalization in the last decade may also affect these bilateral information
flows. As communication costs plummet, information flows across countries may become
cheaper.2 3 In order to check for any structural change in the importance of these
information flows during the period, we introduce a new variable denoted Globalization. It
is constructed as the product of the Information Spillovers vector and a vector that takes
the value 0 for any observation before 1985 and 1 otherwise.
Results of these estimations are reported in the third column of table 2 for each of the
source countries. For Tunisia, the estimated coefficient is positive and significant. This
suggests that after 1985, information spillovers increase their importance in the
determination of Tunisia's export pattern. Note that none of the other variables changed
sign or significance. In the case of Egypt, Korea and Malaysia, the estimated coefficient is
negative but insignificant, with the exception of Malaysia, where it is significant at the 10
percent level. This suggests that bilateral information flows tend to lose their relevance for

Malaysia after 1985.24Again, note that none of the other variables changed sign or
significance.
Interestingly, when estimating equations (5) and (6) for exports from the United States, the
overall fit of the equation and significance were similar to the ones reported in Table 2,
except for the absence of information spillovers, which was highly insignificant (t-statistic
of 0.3). This suggests that these information spillovers across countries tend to be more
important for developing countries where the need for getting noticed and establishing a
good reputation as a reliable exporter is higher. In more developed countries, the need for
establishing a reputation as a reliable business partner may tend to be less rigid, perhaps
due to the existence of more developed legal systems, the country's overall reputation, and
a larger market share in world markets. All of these may make less relevant the intercountry information flow between potential export market.
In order to explore this hypothesis, we created a new variable to capture the notion of
world reputation as an exporter. This is constructed as the market share of a particular
product of the source country in world markets, and is denoted WdRep for world
reputation. In this variable, the information flow between two potential export markets
becomes irrelevant and only its market share in the world market would be of interest for
potential importers in other markets.25
Results of the estimation of equation (6) including WdRepare reported in Table 3 for the
four source countries (Egypt, Korea, Malaysia and Tunisia) and the United States. In the
case of Egypt and Tunisia, WdRep does not enter significantly into the regression (in the
case of Egypt it has a negative sign), but all other variables keep their significance
including information spillovers. For Korea, Malaysia and the United States, WdRep
enters significantly, suggesting that world reputation may be enough to establish a
reputation as reliable exporter in these countries. This is particularly true for the United
States, where information spillovers do not seem to have any explanatory power. In the

18
case of Korea and Malaysia, however, information spillovers still play a significant role (in
Korea they are significant at the 20 percent level).
These results somewhat confirm our hypothesis above: as countries developed, the intercountry information spillovers among potential export markets become less relevant. At
low levels of development or country reputation, inter-country information spillovers tend
to be relatively more important for exporters.
We also tested for the time length of information spillovers by introducing into equation
(6) lags of 2 and 3 years for the Information Spillovers variables. The estimated
coefficients for these lags were smaller and highly insignificant for Korea, Malaysia and
Tunisia, suggesting a short memory in world markets. Again, none of the other variables
changed sign or significance. In the case of Egypt, however, the estimates suggested some
memory in world markets for Egyptian exports, as the lagged variables were statistically
significant.
Finally, note that it is difficult to infer from the reported coefficients the importance of
information spillovers in determining the export patterns of these four countries. In other
words, what is the effect, of a one-dollar increase in export penetration in one particular
market today on exports to the rest of the world in the next period? Do some export
markets generate more information spillovers than others? The answer to these questions is
given in the next section.
6.
Where are Export Information spillovers larger?
The presence of information spillovers implies that an increase in exports in one particular
market will affect the whole system through information spillovers and will therefore be
followed by increases in exports to the rest of the world. To see how a one-dollar increase

information exchange between countries c and k at period t-1; and 7rP,c,is the probability

is non-zero conditional on the explanatory variables.
Table 4 provides such bilateral estimates for a selected number of countries at the mean
(over products and time) using the estimates of the second column of table 2 for each of
the source countries (Egypt, Korea, Malaysia and Tunisia). It suggests that, in the case of
Korean exports, for example, a one-dollar increase in exports to the United States
generates an increase of 0.1 cents in exports to China in the next period and 0.2 cents of
extra exports to Germany. Similarly, a dollar increase in Egyptian exports to India
generates an increase of 0.1 cents in exports to Hong Kong and 0.04 cents to Great Britain
in the next period.
To obtain the total effect in the rest of the world of a dollar increase on exports to country k
through infornation spillovers, one needs to add the left and right-hand-sides of (6) over
all rest-of-the-world countries. That is,

Estimates at the mean (across products and time) of a one-dollar increase in exports to each
of the countries in our samnpleby Egypt, Korea, Malaysia and Tunisia are given in Table 5.
A one-dollar increase in exports to the United States provides, through information
20
spillovers, an increase in exports to the rest of the world of 14 cents for Korea, 10 for
Malaysia, and 2 for each of Egypt and Tunisia.
The United States, however, is not the largest market in terms of generating export
information spillovers for these countries. The largest spillovers for our four source
countries are found in Argentina, Colombia, Hong Kong and India (and France for
Tunisian exports). The reason has to do with the size of the United States' market rather
than the lack of information flows between the United States and the rest of the world. A
large market implies that a dollar increase has very little effect on market shares, which is
the force behind the spillovers, and therefore generates smaller spillovers for the same
amount of information flow.
Countries that generate the lowest spillovers are Panama, Israel, Trinidad and Tobago, and
Korea. The reason for the lack of information spillovers from these markets has to do with
the small amounts of information flows between these countries and the rest of the world,
partly due to their small size.
6.1
Geographic concentration of information spillovers and ethnic networks
Information spillovers can be larger in developing countries. However, they tend to be
geographically more concentrated. In Table 5, the figures in italics show the share of the
top four countries to which information spillovers are generated from each market. The
spillovers of Argentina, India, Pakistan, Colombia and Singapore tend to be relatively
concentrated (regardless of which is the exporting country) compared to some developed
markets such as Spain, United States and Japan. China and Hong Kong, to some extent, are
an exception as information spillovers generated from these developing countries appear to
be geographically diversified. This probably reflects a less geographically concentrated
migration pattern.
The large concentration of information spillovers from developing countries also reflects
the fact that information spillovers occurred across relatively close markets. In the case of
21
Egyptian exports to Argentina, for example, about 70 percent of the information spillovers
generated in Argentina are received by other Mercosur countries (Brazil, Chile, Paraguay
and Uruguay). On the other hand, in the case of information spillovers generated in the
United States, the top four receivers are Canada, Israel, Trinidad and Tobago and Saudi
Arabia, which are geographically dispersed. Note also that they represent only 30 percent
of the total information spillovers generated in the American market.
To illustrate the relatively high regional concentration of information spillovers generated
in developing countries, Figure 2 plots the cumulative distribution for information
spillovers generated from Egyptian exports in Argentina, China, France, Germnany,Hong
Kong, India, Japan, Tunisia and the United States. The horizontal axis is ordered in terms
of geographic distance between each of these countries and the rest of the world.
It is clear from figure 2 that spillovers generated from the United States and France tend to
be geographically more diversified than spillovers generated from Argentina or India.
More than 75 percent of information spillovers from Argentina and India are transmitted
within the five closest countries. For China and Hong Kong, however, only around 50
percent of the total information spillovers are generated within the five closest countries,
whereas in the case of the United States the figure is around 25 percent.26
7.
Concluding Remarks
The exchange of information among (potential) export markets can significantly affect the
export performance of a developing country. A good (or bad) export performance in one
market can affect not only the future export performance in the same market, but also in
"neighboring" markets. This will occur if importers in different countries share
information on the performance of a particular exporter or if exporters themselves take,
advantage of the information acquired while exporting to similar markets. Thus, through
26

22
information spillovers, the overall export success (or failure) becomes cumulative across
markets.
Exports of the four developing countries in our sample (Egypt, Korea, Malaysia and
Tunisia) are significantly affected by these bilateral information exchanges; in particular,
for those in earlier stages of development (Egypt and Tunisia). We found, however, that
bilateral information spillovers across markets are negligible (or non-existent) for exports
from the United States, where the need for creating a reputation in international markets is
smaller. In the case of the United States (and to some extent Korea and Malaysia) the
overall world reputation of the exporter seems to be a more important determinant than the
bilateral exchange of information across export markets. For Egyptian or Tunisian
exporters, bilateral information exchanges across export markets is the dominant
determinant of their export performance.
A dollar increase of Egyptian exports to France generates almost 8 cents of extra exports to
the world in the next period through exchange of information between France and the rest
of the world. An dollar increase to the United States generates 2 cents of exports to the rest
of the world. Similarly, an additional dollar to India can generate as much as 18 cents of
exports to the rest of the world. Similar figures for Tunisian exports are 9 cents for
information spillovers generated from France, 2 cents from the United States and 7 cents
from India.
As suggested by the figures above, some developing countries generate larger benefits for
exporters through information spillovers. That is the case of India for Egyptian exporters.
Also, information spillovers generated in Argentina provide an additional 12 cents in the
next period for each dollar exported to Argentina. This is above the benefits from an extra
dollar to France or the United States. The reason for this is probably that a relatively good
export performance of Egypt in India or Argentina could be more easily noticed than
increased exports to the United States or France, given the relatively smaller size of the
Indian or Argentinian market.
23
However, export information spillovers generated from developing countries also tend to
be geographically more concentrated. The reason has to do with the geographic
concentration of the exchange of information flows in developing countries, which partly
reflects international migration patterns and the presence of ethnic networks, as suggested
by James Rauch's work. The exception in our data is China and Hong Kong. This can be
partly explained by the geographically more diversified migration patterns of China and
Hong Kong.
These results suggest an important role for public or private export information agencies in
developing countries. Diffusion of export information across firms can significantly
contribute to the export performance of a country. The analysis also detected the presence
of externalities at the two-digit industry level, which suggests that there is room for cooperation, for example, through bundling of export offers across firms in the same twodigit industry. More importantly, perhaps, is that the presence of these information
spillovers implies that one bad deal or poor performance in one market not only hurts
exporters in that particular market, but may also hurt them in other markets. This suggests
an important role for quality controls, such as ISO standards, that can be publicly or
privately organized.

Estimation technique is Tobit to control for censored data. Figures in parenthesis are White-Robust
standard errors. * * * stands for significance at the I percent level; * * at the 5 percent level and * at the 10
percent level. For the four countries, all other coefficients are within two standard deviations of the results
reported in the third column of Table 2. For the United States all other coefficients are qualitatively similar to
the ones reported for the other four countries in Table 2 (with the exception of distance, which is
insignificant).
