Introduction
International trade is a key driver of economic growth and poverty reduction [Reis & Farole, 2012; Frankel &
Romer, 1999; Samuelson, 1939; Dollar & Kraay, 2003; Irwin & Terviö, 2002; Krueger, 1998; Balassa, 1982]
Some of the mechanisms through which trade contributes to economic growth include (Samen, 2010;
Brenton & Newfarmer, 2009; Reis & Farole, 2012):
Trade increases potential market size (via exports) - increasing market size means more profits and scale effects leading to growth
Trade increases domestic competition (via imports) – efficiency gain
Trade increases specialization and expands efficiency-raising benefits of comparative advantage (via factor price equalization)
Trade affords greater capacity utilization
Trade induces rapid technological change, and productivity gains leading to wage premiums and job creation (via DCA)
Introduction
Empirical literature also shows a wide consensus on the positive association between trade and economic growth (Edwards, 1992; Krueger, 1997; Wacziarg & Welch,
2003)
Special emphasis on the role of exports • Rapid and sustained economic growth through productivity
gains and technological upgrading (Spence, 2007; Brenton & Newfarmer, 2009)
» Export sectors have higher productivity and
» And within sectors, exporting firms tend to be more productive than non-exporters
Introduction
Following these spectrum of theoretical and empirical grounds and the drive for industrialization, many developing countries have started promoting exports through direct policy incentives and export institutions Particularly, since the 1980s, most developing countries abandoned import
substitution strategies in favor of export-led growth and start to undertake trade reform measures as part of the Structural Adjustment Program (SAP)
Since then designing policies that promote trade and trade competitiveness have been at the heart of growth strategies for developing countries
Likewise, since the early 1990s Ethiopia has been striving to set the right conditions for increasing exports Overall economic liberalization and macroeconomic stability reforms Introduction of several export incentive schemes Set up a number of export support institutions (ESI) aimed at boosting
exports in general and manufactured exports in particular

Research Objectives and Questions
So our goal in this paper is to analyze Ethiopia’s export performance and dynamics over the period 1995 to 2014 Ethiopia’s trade/export patterns Export growth characteristics
What characterizes and drives export growth? How concentrated/diversified are Ethiopia’s exports in
terms of exporters, products, and markets?
Export Dynamics and Survival Over the past decade or so, has Ethiopia added
economically significant numbers of new products and markets to its export portfolio?
And to what extend do Ethiopian exporters survive beyond their first year of entry to the export market?

Section 1: Aggregate Data
Trends in Ethiopia’s Exports, Imports and GDP
Figure 1: Trends in Exports, Imports and GDP of Ethiopia (1995- 2013)
• High import growth following the rapid increase in GDP after 2003
• Increase in exports not equally remarkable
• As a result, trade deficit widened
Ethiopia: Trends in Trade Growth
Figure 6: Annual Growth Rates of Exports of Goods and Services in Ethiopia (1995-2013)
• The growth rates in exports over the reviewed period have been positive except for the negative growth rates observed in 1999 and 2012 and the close to zero rates in 2008 and 2009.

Ethiopia: Trends in Trade Growth
We observe large annual fluctuations in the level and growth of exports (see Figures 6 and 7) – This is driven largely by changes in international commodity
prices of major exports such as Coffee • For example, the country's strong export performance recorded in
2010 and 2011 can largely be attributed to the rise in international commodity price in general and that of coffee in particular
• Similarly, the negative export growth rates observed in 2012 appears to coincide with the fall in international commodity price particularly that of coffee
– This co-movement of international commodity price and Ethiopia's export performance clearly shows how the country is heavily reliant on commodity exports and signals the need for further diversification of the country’s exports base

Key Trade Performance Indices
Discussion on trade performance commonly revolves around 3 questions – how much, what and with whom a country trades
We focus on two key performance measures
1) Trade Openness (at the aggregate level)
Measures a country’s ability to integrate in global trade
2) Trade Composition
Sectoral and geographic compositions
(1) Overall Openness Measures
Raw Trade Openness – measured as the sum of imports and exports over GDP Common measure but has defects (e.g., cross country
comparison is difficult because openness is correlated with country characteristics such as income, location, size, etc)
For example, while smaller countries (such as Singapore, Belgium, etc) appear to have higher levels of trade share in GDP, large countries such as the U.S. and Japan appear to have the lowest level of trade share in GDP. (This is so because larger countries trade more with themselves)
Relative Trade Openness – measures a country’s trade share in world trade Corrects for some of the weaknesses of the raw measure but
cross-country comparisons still remain difficult
Adjusted Trade Openness – controls for the influence of country characteristics through regression analysis Generates meaningful comparisons
Raw Measure: Ethiopia’s Trade Openness
Figure 2: Trends in Shares of Trade, Exports and Imports of Goods and Services in GDP Ethiopia
(1995-2013)
26%
51% 40% Mainly attributed to the rapid increase of imports
During the 2006-2009, rapid growth rate of GDP was largely driven by growth in the non - tradable (service sector)
Improvements in international commodity prices.
Raw Measure: Ethiopia’s Trade Openness
Figure 3: Trends in Shares of Merchandise Trade, Exports and Imports in GDP Ethiopia (1995-2013)
• Trend is similar but the share of merchandise exports in GDP remains flat and its contribution to the overall merchandise trade openness is meagre
• In the case of merchandise, it is clear that the overall trade openness is to a greater extent dictated by trends in share of merchandise imports in GDP.

Adjusted Trade to GDP Ratio: Regression Analysis to Control for Country
Characteristics Having a lower trade share in GDP doesn't necessarily mean that
the country in question is less open to international trade In fact, these countries might be trading as much as they would be expected to trade
given their size, level of development and geographical location etc
In order to measure correctly how much a country trades relative to how much it can be expected to, given its fundamentals, one can run a trade-openness regression of the type
𝑂𝑖 = 𝛼0 + 𝛼1𝑌𝑖 + 𝛼2𝐴𝑖 + 𝛼3𝑅𝑖 + 𝛼4𝐿𝐿𝑖 + 𝛼5𝐼𝐿𝑖 + 𝑈𝑖
Where Yi is GDP per capita (2005 USD); Ai is area in sq. kms; Ri is remoteness index; LLi and ILi are dummies for landlocked and island; and Ui is an error term.
Remoteness index measures a country’s average weighted distance from its trading partners (Head, 2003), where weights are the partner countries’ shares of world GDP
Since the distance variable used in calculating the remoteness index is measured between capitals of trading partners, it is can also capture internal cost of transportation
Country size measured by total population and land size
Adjusted Trade to GDP Ratio: Regression Analysis to Control Country
Characteristics
The difference between 𝑂𝑖 and its predicted value,
𝑂𝑖 , can be taken as an adjusted indicator of openness, i.e., adjusted for the structural factors included in the model
Positive – trades more than it can be expected to
Negative – trades less
Zero – trading as expected

Adjusted Measure: Ethiopia’s Trade Openness
2009-2013 period Ethiopia traded 10 percentage points less than what
would be expected once the influence of the factors is accounted for
Using this adjusted measure, Sub Saharan African countries (including Ethiopia), on average, appear to be relatively more open compared to North America and Latin America and Caribbean regions once the influence of these factors is taken into account (contrary to what the "raw" measure of openness reported earlier)
When we further control for inland costs of trading (local costs associated with exporting and importing), Ethiopia becomes relatively less open - trades 13 percentage points less than would be expected.
Figure 5: Adjusted Openness to Trade for Sub-Saharan African Countries (Average of
2009 - 2013)
Adjusted Measure: Ethiopia’s Trade Openness
Ethiopia - 14th least open based on models 3 & 4
Ethiopia - 6th open when comparison is made based on the "raw" measure of openness.
(2) Trade Composition: Sectoral Composition of Exports
• Agriculture still largest contributor to Ethiopia’s merchandise exports - accounting for close to 87 percent, on average, during the past decade (2005/06 – 2014/15)
• While the manufacturing sector contributed about 7 percent for total merchandise exports, all the other sectors (minerals, base metals, etc) account for about 7 percent during the same period
• The other interesting observation is that although still dominant the export value share of Agriculture fell from 88 percent in 2005/2006 to 85 percent in 2014/2015
• On the other hand, the export value share of Manufacturing rose from 6.6 percent in 2005/2006 to 10 percent in 2014/2015. – Although these are small changes, this would
suggest that Ethiopian exporters are slightly diversifying into higher value sectors and sectors that are not heavily affected by external price and demand shocks.
– Likewise, in terms of the number of exporters, agriculture has the largest number of exporters followed by the manufacturing sector.
– On the contrary, the number of exporters is smallest in Mineral and Base Metals sectors.
(2) Trade Composition: Geographical Composition of Exports
In terms of geographic composition, modest diversification away from traditional partners such as Europe

5 Conclusions
Export Base – measured in terms of number of exporters, products and markets
Export diversification – a measure of risk and vulnerability arising from relying on a narrow range of exporters, products and markets – It makes countries less vulnerable to demand shocks and price swings in
overseas markets by stabilizing export revenues (Ghosh & Ostry, 1994) – Creates greater opportunities through knowledge spillovers and increasing
returns to scale, which are critical to long-run growth (Amin Gutiérrez de Piñeres & Michael, 2000; Hausmann & Klinger, 2006)
As argued by (Samen, 2010), export diversification takes the following forms: – Horizontal diversification - within the same sector (primary, secondary or
tertiary) – Vertical diversification entails a shift from the primary to the secondary or
tertiary sector (e.g., moving from basic commodity extraction to commodity processing)
– Diagonal diversification entails a shift from imported inputs into the secondary and tertiary sector (e.g., using imported goods to produce manufactured products for exports)
Export Base and Diversification
Export Base and Diversification
Diversification is critical in any trade strategy (Reis & Farole, 2012) Justified to avoid the so-called “natural resource curse”
(a negative correlation between growth and dependence on primary commodity exports) (Sachs and Warner, 1999)
In addition, diversification at the extensive margin reflects “export entrepreneurship” (Hausman & Rodrik, 2003)
History: few countries have developed quickly on the basis of exports of primary products alone
Ethiopia’s Export Base and Diversification
In order to investigate export diversification performance in Ethiopia more robustly, we consider the following diversification measures: 1) Number of exporters, export products and destination
markets a simple count
2) Share of top exporters, products and markets Top 1, 5 and 25 percent
3) Theil Diversification Index Within and between-group diversification
4) Extensive and Intensive Margins: Export Growth Decomposition What is the contribution of the extensive margin?

3. Ethiopia’s Export Base and Diversification – Theil Index
The Theil Export Diversification Index Theil’s index is another widely used diversification measure – upper
limit is ln(n) and lower limit is zero
The higher the Theil index, the higher the concentration (or the lower the diversification)
Theil’s index is decomposable - additively to measure diversification within (intensive) and among groups (extensive) of exports
Changes in the within-group Theil index measure changes at the intensive margin (i.e., changes in concentration among active lines only)
Changes in the between-groups component of Theil’s index measure changes at the extensive margin (i.e., proportional changes in the number of active lines)
Our results for the intensive (within) and extensive (between) Theil indices are based on the definitions and methods used in (Cadot, Carrère, & Strauss-Kahn, 2011)
3. Ethiopia’s Export Base and Diversification – Theil Index
Following (Cadot et al., 2011), Theil’s entropy index (Theil, 1972) is given by:
Let 𝑛 denote the number of export products (products are defined at the 4-digit SITC (Rev. 1) level), 𝑛
𝑗 the number of export lines in group 𝑗, µ the average dollar export value, µ
𝑗
group 𝑗’𝑠 average dollar export value, and 𝑋𝑘 the dollar value of export line 𝑘. Then the
between-groups component is:
And the within-group (intensive margin) component is
Where
3. Ethiopia’s Export Base and Diversification – Theil Index
Overall Theil index and its components are calculated for Ethiopia for the period 1993 – 2010 (where data is available) – Results based on an updated version of the UN–NBER dataset as compiled
by the IMF, which harmonizes COMTRADE bilateral trade flow data at the 4-digit SITC (Rev. 1) level
– Results are consistent with earlier measures - Ethiopia’s export diversification has generally remained low through out the period Compared to the Sub-Saharan average, Ethiopia performed lower than
the average until the year 2001, beyond which Ethiopia’s diversification appears to be better than the Sub-Saharan average
Compared to many Sub-Saharan African Countries including Kenya, Tanzania, Uganda, Mauritius, Zimbabwe and Madagascar
However, Ethiopia does better than some Sub-Saharan countries such as Mozambique, Ghana, Rwanda, Malawi and Sudan in terms of export diversification
Since 2001 Ethiopia has shown some improvements in terms of diversifying its exports compared to the period 1994 – 2000

4. So, What Drives Export Growth? Roles of IM and EM
To understand what drives short run export growth (or contraction), we consider a simple decomposition of the change in exports between consecutive years
Following (Cebeci, Fernandes, Freund, & Pierola, 2012), if 𝑡 designates a year, 𝑋 designates total exports and 𝑛 is the number of exporters, then total exports in a given year (𝑋𝑡) is simply the product of the number of exporters in a given year (𝑛𝑡) and the average exporter size in a given year (𝑆𝑡):
𝑋𝑡 = 𝑛𝑡 ∗ 𝑆𝑡
Thus, the change in exports between years 𝑡 − 1 and 𝑡 can be written as:
𝑑𝑋𝑡 = 𝑛𝑡 ∗ 𝑑𝑆𝑡 + 𝑆𝑡 ∗ 𝑑𝑛𝑡 – where 𝑑𝑆𝑡 is the change in the average exporter size between years 𝑡 − 1 and 𝑡, 𝑑𝑛𝑡 is the change in the number of
exporters between years 𝑡 − 1 and 𝑡, 𝑛𝑡 is the average number of exporters across years 𝑡 − 1 and 𝑡, and 𝑆𝑡 is the average exporter size across years 𝑡 − 1 and 𝑡.
The contribution of the intensive margin (IM) to a change in exports is given by:
𝐼𝑀 = 𝑛𝑡 ∗𝑑𝑆𝑡𝑑𝑋𝑡
And the contribution of the extensive margin (EM) to a change in exports is given by:
𝐸𝑀 = 𝑆𝑡 ∗𝑑𝑛𝑡𝑑𝑋𝑡
4. So, What Drives Export Growth? Roles of IM and EM

o While expansions in existing trade flows (the intensive margin) explained more than 92 percent of the overall changes in merchandize exports, the extensive margin explained, on average, only about 8 percent o Indicates the existence of weak diversification in terms of new products and markets
Average Exporter Size – How Large is the Average Ethiopian Exporter?
Exporter size (measured by mean exports per exporter) is about 1.15 million USD (WB: average for developing countries is about 2.21 million USD)
Difference in Average Exporter Size: The Top vs the Bottom
– In terms of contribution to the national export value, the top 10 percent of exporters (an average of 175 firms over the period 2005/2006 – 2014/2015) contributed a very high share of exports – close to or more than 80 percent over the past decade (2005/2006 – 2014/2015)
– The difference in the average exporter size (measured by mean exports per exporter) in the top 10 percent and bottom 90 percent of exporters is simply tremendous In 2014/2015, while the average export value among firms in the top 10
percent of exporters is 13.7 million USD, the corresponding value for firms in the bottom 90 percent is only 0.5 million USD
Considering a longer period (2005/2006 – 2014/2015), the mean export per exporter (or average firm size) has been 9 million USD for the top 10 percent and 0.26 million USD for the bottom 90 percent
This means that over the entire period, an exporter in the top 10 percent of exporters is, on average, about 35 times larger in size than an exporter in the bottom 90 percent of exporters (see Table 7)

Table 8: Entry and Exit of Ethiopian Exporters (2006/2007 - 2014/2015). Source: ERCA
Export Dynamics - Firm Entry and Exit Rates Ethiopian exporters exhibited high degree of exporter churning over
the past nine years (2006/2006 - 2014/2015) – Export firm entry rate averaged 34.3 percent – Firm Exit Rate averaged 31.8 percent – Consistent with a number of studies who find rates of entry into
exporting of 30-60 percent a year (e.g., see Alvarez and Lopez, 2008 for Chile; Eaton, Eslava, Kugler and Tybout, 2008 for Colombia; Volpe-Martincus and Carballo, 2008 for Peru; and Albornoz et. Al., 2010 for Argentina)
Both entry and exit rates initially increased and peaked in 2010/2011 and slowed down since then until the current period 2014/2015. – But, the number of entrants is consistently higher than the number of
exiters between 2006/2007 and 2010/2011. – The opposite is true for the period between 2011/2012 and 2014/2015 – However, the gap between the two rates shrinks towards the end of the
analysis period.
Overall, net firm entry has been 2.5 percent on average over the past nine years

Export Dynamics - Product and Market Entry and Exit Rates
Similar to the exporter churning, product and market churning is also relatively high in the Ethiopian export market – Product entry rate averaged at 57.9 percent over the past nine
years (2006/2007 – 2014/2015) – While product exit rate has been 57.6 percent – Relatively high product entry, however, most of these new products
die out as can be seen from the high product exit rates, which suggests accidental deaths beyond experimentation
Likewise, market entry and exit rates have been high, 56.2 and 55.4 percent respectively
Overall – Net Product entry rate averaged at 0.28 percent – Net market entry rate has been positive in all the years over the
past 9 years (2006/2007 – 2014/2015) averaging at about 1 percent

Ethiopia: Exporter Firm Survival
• For any developing country, survival (the ability of those new export portfolios to survive and thrive in export markets) is as important as entry (Reis J. G., 2011; Cebeci, Fernandes, Freund, & Pierola, 2012)

Definition
Ethiopia: Exporter Firm Survival
1-Year Survival Rate On average, about 60 percent of the new entrants survive for just
one year High variability in firm survival rate (ranging from 37.9% to 85.5%) In the current year 2014/2015, firm survival rate is 50 percent,
which is lower than the eight-year average, suggesting that entrant firms have recently been experiencing trouble remaining in the export market
2-year and 3-year Survival Rates Again, high variability in firm survival (ranging from 18.8 to 51.4
percent) and the 3-year firm survival rate (ranging from 14.9 to 43.3 percent)
Survival beyond the first year becomes more and more difficult And the survival rate for 1-year, 2-year and 3-year survivors in the
current year 2014/2015 is much lower than the previous three years; indicating that firms recently have had trouble remaining in the export market relative to the last 3 years

5 Conclusions
Conclusions
Several key patterns emerge from our analysis
– Falling Agriculture and rising Manufacturing Although these are small changes, this would suggest
that Ethiopian exporters are slightly diversifying into higher value sectors and sectors that are not heavily affected by external price and demand shocks
– Increasing roles of more dynamic and emerging markets in Asia, Latin America, Sub-Saharan, etc EAP, Sub-Saharan Africa, LAC
Conclusions
Several key patterns emerge from our analysis – In any one year, almost all export expansion or
contraction comes from changes in exports by existing firms (the intensive margin)
– This dominance of existing firms is despite the fact that one-third to one-half of all exporters are new entrants in a typical year
– These new firms by and large do not add much to export growth simply because (i) the majority do not last more than a year and (ii) their export sales are very small
– Each year, large numbers of new exporters enter the export market, but most drop out after 2 years of export. And even much smaller after 3 years Death beyond experimentation
Conclusions
• But Still Sources of Vulnerability Remain – Ethiopia’s export sector remains heavily dependent on
primary commodity exports and a few large exporting firms • The top 10 percent exporters (only 175 firms on average
between 2005/06 – 2014/15) contributed close to or more than 80 percent of the country’s exports
• So, while export value has shown a modest increase, it is dominated and driven by the top tier of larger exporters and few export products
– Similarly, in terms of destination markets, Ethiopia’s exports are focused on a small number of countries (135 markets out of a total of 247 potential markets)
– Limited diversification – the extensive margin’s contribution to overall export growth is weak, unable to expand the country’s export base
Policy Issues?
• If most of your export values are coming from a few top (superstar) exporters, should export promotion target SMEs?
• Should policy target more entry or longer survival?
– Virtuous export growth theory – survival as important as entry?
• Is knowing what to export is as important as knowing where to export?
