Free trades allows firms or industry to take advantage of economies of scale.
Protected markets limit gains from external economies of scale by inhibiting the concentration of
industries:
Too many firms to enter the protected industry. The scale of production of each firm becomes
inefficient.
Free trades avoids the loss of resources trough rent seeking
Spend time and other resources seeking quota rights and the profit that they will earn.
The political argument for free trade says that free trade is the best feasible
political policy, even though there may be better policies in principle.
The cases against free trade
An export tax that completely prohibits exports leaves
a country worse off, but an export tax rate may exist
that maximizes national welfare trough the terms of
trade.
Ignores the likelihood that other countries may retaliate against large countries
by enacting their own trade restrictions
A tariff rate that completely prohibits imports leaves a country worse off, but
tariff rate tO may exist that maximizes national welfare: an optimum tariff.
A second argument against free trade is that domestic market failures may
exist that cause free trade to be a suboptimal policy.
The domestic market failure argument against free trade is an example of a
more general argument called the theory of the second best.
Government intervention that distorts market incentives in one market may
increase national welfare by offsetting the consequences of market failures
elsewhere.
Types of market failures
1. Persistently high underemployment of workers
2. Persistently high underutilization of structures,
equipment and other forms of capital. 3. Property rights
not well defined or well enforced 4. Economists calculate
the marginal social benefit to represent the additional
benefit to society from private reduction. 5. When tariff
increases domestic production, the benefit to domestic
society will increase due
Economists calculate the marginal social benefit to represent the additional
benefit to society from private production.
It’s possible that when a tariff increases domestic production, the benefit to
domestic society will increase due to a market failure.
International negotiations of trade policy
After rising sharply at the beginning of the 30s, the average of the
US tariff rate has decreased substantially from the mid-30s to 1998
Multilateral negotiations mobilize exporters to support free trade
if they believe export markets will expand.
Also help avoid trade war between countries. Result if each country
has an initiative to adopt protection, regardless of what other
countries do.
Preferential trading agreements
Are trades agreements between countries in which they lowest tariffs for each other but not for the
rest of the world.
Free trade area
Customs union
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.
Trade creation
Occurs when high cost domestic production is replaced by low cost imports from other countries.
Trade diversion
Occurs when low cost imports from nonmembers are diverted to high cost imports from member
nations.
World trade organization negotiation
address trade restrictions in at least 3
ways
1. Reducing tariff rates through multilateral negotiations
2. Binding tariffs rates 3. Eliminating non tariff barriers
WTD is based in a number of agreements:
• General Agreement on Tariffs and Trade
• General Agreement on Tariffs and
Services • Agreement on Trade-Related
Aspects • The dispute settlement
procedure • The GATT multilateral
organization in the Uruguay Round
