This is a hierarchy determined by the removal of restrictions to the free flow of goods, services,
and factors of production between member countries:
1.
A free trade area
2.
A customs union
3.
A common market
4.
An economic union
5.
A political union
1.A
free trade area:
it eliminates all barriers to trade goods and services among member countries,
but members determine their own trade policies for non-members.
the European Free Trade Association (between Norway, Iceland, Liechtenstein, and
Switzerland)
the North American Free Trade Agreement (between the US, Canada, and Mexico- now
superseded by USMCA)
the Closer Economic Relations CER (between Australia and New Zealand)
Member countries shave common policies among the members but have different policies
for the non-members.
2.A
customs union:
it eliminates trade barriers between member countries and adopts a common
external trade policy:
The Andean Community (between Bolivia, Columbia, Ecuador, and Peru) is an example of a
customs union.
Gulf Cooperation Council (between Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the
UAE).
3. A
common market
has no barriers to trade between member countries, a common external
trade policy, and the free movement of the factors of production:
MERCOSUR (between Brazil, Argentina, Paraguay, Uruguay, and provisionally since 2006,
Venezuela) is aiming for common market status.
4.An
economic union
has the free flow of products and factors of production between members, a
common external trade policy, a common currency, harmonised tax rates, and a common
monetary and fiscal policy:
The European Union (EU) is an imperfect economic union.
5.A
political union
involves a central political apparatus that coordinates the economic, social, and
foreign policy of member states:
The EU is headed toward at least partial political union, and the United States is an
example of an even closer political union:
-The United States of Europe
