1. Understanding
Trade
… and a debate
on perceptions
Trade is good for you…
under certain conditions
Bad and good farming and
public perception

CEU
Master course Economics
2. Issues covered
Why should trade be good?
The limitations of the comparative advantage
theory: A banana is not a car…
WTO
Uruguay round agreements…
Measures of support used and … their limits
Tariffs, types and consequences
Non tariff barriers
Debate on food safety, GMOs, public perception of
risk
3. David Ricardo
and comparative advantage
Trade economics is founded on the theory of
comparative advantage
The origins of Trade economics are from David
Ricardo and his theory of comparative advantage
in Trade
The logic is simple. Each country has different
endowments, thus some countries are better in
some things than others.
By trading what you are good at (low opportunity
cost), you can de facto get what you are not good
at (high opportunity cost) cheaper price.
Specialisation benefits you.
The opportunity costs are different.

model (absolute advantage)

If they trade they can
Specialise
Global output would
be higher
Now 45 apples
40 bananas
Now they trade
If each do only one:
60 apples
70 bananas
C1 gives 30 apples for
25 bananas
Country 1 Country 2
Both are better off

6. We are all happy… but…
Products are not equivalent, if we put bananas and
cars and both have absolute advantage, trade
expands but the value added of products is very
different. Bananas are also land dependant, imagine
islands.
Most countries are trapped in poverty because of low
value added.
Study of 154 countries (Felipe et al.):
There are only 34 countries in the world that export
mostly sophisticated and well-connected products –
high tech + services
28 countries in the world that are in a “middle product
trap,”
17 countries that are in a “middle-low” product trap,
and 75 countries that are in a difficult and precarious
“low product trap.”

8. What does
development require…
Human capital: Solow growth model fallacy ‘A’
technical change is NOT exogenous, now well
recognised
Infrastructure and administrative capacity
Protection or high capital for investment as entry
costs high (barriers for infant industry argument?)
Contradicts drive for free trade, free trade increases
barriers to new entrants, increases opportunity costs.
Indirect support in richer countries makes it harder
=> WTO conundrum.
Free trade is fine, but not ‘per se’ in all
circumstances. It is specially AFTER you have the
structures in place
9. Trade liberalisation in agriculture
slowing down . Why? History of GATT
and WTO
EU and US were affecting strongly world price of
agriculture
Rich countries liberalised manufacturing before
developing countries had a say.
OECD measured consumer and producer support
equivalents CSE – PSE, which measure the subsidy
or tax of policies on producers and consumers.
The GATT (WTO) agrees on methodology to
calculate the AMS (Aggregate Measure of
Support)
10. GATT: 1946-1995
from 1995: WTO
Seven Rounds of Negotiations
Most famous Uruguay Round 1986-1991, first
agriculture agreement
Tariffication of barriers
Tariff reductions
Distorting subsidy estimation, limitation and phasing
out
Doha Development Round… the never ending
Round since 2001 – maybe it does not tackle real
issues?
11. Free trade is double sided
Are green box policies not curtailing markets for
developing countries?
LDCs got free trade access (e.g. EU – EBA), but
more trade liberalisation also cuts their relative
advantage, in particular ACP (African, Caribbean
and Pacific) countries had special agreements.
Getting rid of tariff barriers is nice, but NTBs (Non
tariff barriers) are growing.
SPS (Sanitary and Phytosanitary) rules are creating
new barriers
Rules of origin agreed hamper trade.
Developing countries want more fairness.
12. Treatment
of developing countries
GATT rules of MFN (Most favoured Nation) mean
that all countries have to be treated same
Exception for DCs: GSP (Generalised System of
Preferences) for preferential access since 1971
EU’s EBA has limited effect
This is why in BALI meeting (Dec 2013) the real
deal was on technical assistance to facilitate
trade from LDCs
Further trade liberalisation could actually harm
LDCs
13. Increase in non trade barriers
SPS rules expand
EU makes unscientific anti GM policy (with
unintended results?)
Due to SPS changes rejections of imported goods
to EU multiply over the years.
EU introduces fork to farm – traceability creating a
costly process and impossible to comply for
developing country smallholders – fosters large
producers specialised in exports
SPS rules not based on scientific standards and
subjective.
EU approach to safety based on flawed
precautionary principle – minimax approach
14. Unrealistic worse case scenario is weighted against
maximum benefits, regardless of probability of
worse case scenario. As 100% food safety is
impossible, rules become draconian.
Aflatoxins standards of EU for example. Rare
disease. EU imposes standards far above
international CODEX (FAO). Death risk 1,4 per billion
people avoided, but killed 64% OF AFRICAN
IMPORTS of cereals fruits and nuts, causing
devastating economic misery and most probably
death due to poverty.
15. Back to tariffs
Tariffs have fallen since the Uruguay Round, but the
methodology used limited effective tariff
reductions, because cuts were on average tariffs
(36%), so countries can chose what to cut.
We look at:
Tariff peaks (over 15%)
In 33 over 200% in some even 1000% mainly
agriculture
Tariff escalation, higher tariffs products in increased
level of processing
Doha’s attempt to move against tariff peaks and
escalation has not yet worked
16. Effects of tariff
peaks and escalation
They both reduce trade in key commodities
Tariff escalation directs exports of developing
countries to products or markets with lower tariffs
(lower value added normally), limiting the
opportunities of diversification
Tariff escalation reduces the capacity of
developing countries to expand their exports
beyond raw material products to processed
higher value-added goods
Tariff peaks, if combined with escalation and/or
tariff quotas, limit imports de facto to levels
controlled by the country offering the quotas.
