2. Introduction
ďŽ
ďŽ
âMultilateralismâ refers to the GATT/WTO system as well as the trade
negotiations that take place among all GATT/WTO members as a group
Recall that one of the founding principles of this system is
nondiscrimination
ď§ Involves the most favored nation (MFN) and national treatment (NT) subprinciples
⢠Each WTO member must grant to each other member treatment as favorable as
they extend to any other member country
ďŽ
âRegionalismâ refers to a violation of the nondiscrimination principle in
which one member of a regional trade agreement (RTA) discriminates in
its trade policies in favor of another member of the RTA and against
nonmembers
ď§ Has been allowed by the GATT/WTO under certain circumstances
⢠Free trade areas (FTAs)
⢠Customs unions (CUs)
⢠Interim agreements leading to a FTA or CU âwithin a reasonable length of timeâ

3. Introduction
Regionalism and multilateralism represent
two alternative trade policy options
ďŽ When multilateralism âfaltersâ regionalism
âpicks up the paceâ
ďŽ
ď§ Nearly every member of the WTO is also a
member of at least one RTA
ď§ Over 150 RTAs exist

Agreements

5. Regional Trade Agreements
ďŽ
Consider two countriesâBrazil and Argentina
ď§ Suppose these countries initially pursue independent and
non-preferential trade policies
⢠Trade policies of these two countries are not coordinated in any
â˘
ďŽ
way and do not discriminate among countries
There is no integration of the countriesâ labor, capital, and money
markets
First-level RTA is known as preferential trade area
ď§ Brazil and Argentina lower their trade barriers between
ď§
each other, but do not eliminate them
⢠Labor and capital markets remain unintegrated
Because the two countries have not fully eliminated trade
barriers between each other, this type of RTA is not
allowed by the WTO

6. Regional Trade Agreements
ďŽ
Second-level RTA is known as free trade area
ď§ Brazil and Argentina eliminate the trade barriers between each other
ď§ With regard to non-member countries Brazil and Argentina pursue
independent policies
Labor and capital markets remain unintegrated
ďŽ
ď§
Third-level regional agreement is known as customs union
ď§ Brazil and Argentina eliminate the trade barriers between each other
ď§ Additionally, member countries adopt common trade barriers with
regard to non-member countries (often referred to as a common
external tariff)
Labor and capital markets remain unintegrated
ďŽ
ď§
Fourth-level RTA is known as common market
ď§ A customs union in which labor and capital markets are integrated
into a regional market
⢠Any restrictions on movements of labor and physical capital (direct
foreign investment) have been removed

7. Regional Trade Agreements
ďŽ
WTO members who wish to form FTAs or CUs may
do so
ď§ However, there are certain requirements
⢠Trade barriers against non-members cannot be âhigher or more
â˘
â˘
â˘
restrictive thanâ those in existence prior to the FTA or CU
FTA or CU must be formed âwithin a reasonable length of timeâ
FTA or CU must eliminate trade barriers on âsubstantially all the
tradeâ among the members
With regard to services, the General Agreement on Trade in
Services (GATS) requires that the FTA or CU involve âsubstantial
sectoral coverageâ

8. Regional Trade Agreements
ďŽ
How to determine whether a product is from a
partner country
ď§ Suppose that Brazil and Argentina form a RTA
⢠Shirt produced in Venezuela is imported into Brazil and label
â˘
â˘
âMade in Brazilâ is attached
Shirt can then be imported into Argentina with no restrictions or
tariffsâproduct is not really made in Brazil
To protect against such possibilities, RTA members usually
define rules of origin
ď¨
Can be defined in a number of ways, including by
ď§ Amount of value added in an RTA partner country
ď§ Degree of product transformation

9. The Economic Effects of
Regional Trade Agreements
ďŽ
Trade creation
ď§ Occurs when the formation of a FTA or CU leads
to a switching of imports from a high-cost source
to a low-cost source
⢠Tends to improve welfare
ďŽ
Trade diversion
ď§ Occurs when imports switch from a low-cost
source to a high-cost source
⢠Tends to worsen welfare

10. Trade Creation and Trade
Diversion
Letâs discuss trade creation and trade
diversion using country specific examples
ďŽ Along with Brazil (B) and Argentina (A), we
are also going to refer to a third country,
Venezuela (V)
ďŽ
ď§ Brazil and Argentina are members of a RTA,
whereas Venezuela is not

11. Trade Creation
ďŽ
ďŽ
ďŽ
Before the RTA, Brazil has in place a specific (per unit) tariff
on imports from both Argentina and Venezuela
Argentina is the lower-cost producer in comparison to
Venezuela
ď§ Therefore Brazil imports good from Argentina
Once Brazil joins either a FTA or CU with Argentina, tariff is
removed on imports from Argentina
ď§ Good continues to be imported from Argentina and imports increase
because price has fallen due to removal of tariff
ďŽ
ďŽ
Consumer surplus in Brazil increases while producer
surplus and government tariff revenue falls
Net increase in welfare due to trade creation

12. Trade Diversion
ďŽ
ďŽ
ďŽ
ďŽ
ďŽ
Before the RTA, Brazil has in place a specific (per unit) tariff
on imports from both Argentina and Venezuela
Assume Venezuela is now the lower-cost producer in
comparison to Argentina
ď§ Brazil imports the good from Venezuela
Once Brazil joins a FTA or CU with Argentina, however,
Brazil switches to Argentina as an import supplier
ď§ Imports expand as the domestic price falls
Consumer surplus in Brazil increases while producer
surplus and government revenue falls
Whether net welfare effect is positive or negative depends
ď§ If trade-diverting effects outweigh trade-creating effects then RTA
will reduce welfare in Brazil

13. Regional Trading Agreements
(cont.)
ďŽ
Regional/preferential trading agreements increase national
welfare when new trade is created, but not when existing
trade from the outside world is diverted to trade with
member countries.
ďŽ
Trade creation
ď§ occurs when high cost domestic production is replaced by low cost
imports from other members.
ďŽ
Trade diversion
ď§ occurs when low cost imports from non-members are diverted to
high cost imports from member nations.
14. Trade Creation
ďŽ
ďŽ
ďŽ
ďŽ
ďŽ
ďŽ
Three countries: Britain($8)>French($6)>US($4) for wheat
production.
Suppose British Import tariff =$5.
Suppose Britain and French forms a customs union.
British consumer will buy products domestically since
8<9<11 without a customs union
With a CU, then British consumer will purchase from his
member countryâFrench since 6<8.
This is trade creation since Britain only needs to pay $6 to
foreign country compared to its own initial cost $8.
15. Trade Diversion
ďŽ
ďŽ
ďŽ
ďŽ
ďŽ
ďŽ
Three country: Britain($8)>French($6)>US($4) for wheat
production.
Suppose British Import tariff =$3.
Suppose Britain and French forms a customs union.
British consumer will buy products from U.S. since 7<8
without a customs union
With a CU, then British consumer will purchase from his
member countryâFrench since 6<7.
Trade diversion: (1) US wheat is really cheaper than French;
(2) Import Tariffs revenue disappear.
16. Welfare Effects of Trade
Creation
ďŽ
PPâ is the partner-country supply curve.
ďŽ
Tariff removal cuts domestic price from OT to OP,
expands imports to MâNâ, and raises welfare by areas
2+4.
ďŽ
Here supply curve is perfectly elastic supply so that
unlimited quantity is available at price OP.
ďŽ
British consumers enjoy a gain in surplus 1+2+3+4.
ďŽ
But area A is formerly the production gain.
ďŽ
Area 3 is the tariff revenue.
ďŽ
Net benefit=2+4=production benefit + consumption
benefit
18. Welfare Effects of Trade
Diversion
ďŽ
Britain and France form the CU, but US has a lowest
cost.
ďŽ
Pb indicates pretariff supply price in partner countryâ
France
ďŽ
Pc is the pretariff supply price in the U.S.
ďŽ
Tariff preference lowers internal price from Tc to Pb.
ďŽ
Lowering a tariff (even preferentially) allows a gain to
British consumers (areas 3+4)
ďŽ
But areas 3+5 measure the total tariff revenue.
ďŽ
Therefore, welfare loss occurs if area 5 exceeds area 4.
20. Net Gains or Losses?
ďŽ
For trade creation predominates trade diversion, UK and
FR should be actually competitive before the union and
potentially complementary after it comes into effect.
ďŽ
Trade creation gains are greater when protected
production is reduced more.
ďŽ
This happens when protective tariffs have made the
output pattern of the two economics look similar.
ďŽ
To avoid trade diversion, each member of the PTA must
also be the most efficient producer of goods protected.
