Tariffs
Why restrict trade?
Benefits of free trade come in the long
term, and are usually spread widely across
society
Costs of free trade are felt rapidly and are
usually concentrated in specific sectors of
the economy
Carbaugh, Chap. 5

Tariffs
Defining tariffs
A tariff is a tax (duty) levied on products as
they move between nations
Import tariff - levied on imports
Export tariff - levied on exported goods as they
leave the country
Protective tariff - designed to insulate domestic
producers from competition
Revenue tariff - intended to raise funds for the
government (no longer important in industrial
countries)
Carbaugh, Chap. 5

Tariffs
Types of tariff
Specific tariff
Fixed monetary fee per unit of the product
Ad valorem tariff
Levied as a percentage of the value of the
product
Compound tariff
A combination of the above, often levied on
finished goods whose components are also
subject to tariff if imported separately
Carbaugh, Chap. 5

Tariffs
Effective rate of protection
The impact of a tariff is often different from
its stated amount
The effective tariff rate measures the total
increase in domestic production that the
tariff makes possible, compared to free
trade
Carbaugh, Chap. 5

Tariffs
Effective rate of protection (cont’d)
When tariff rates are low on raw materials
and components, but high on finished
goods, the effective tariff rate on finished
goods is actually much higher than it
appears from the nominal rate
This is referred to as tariff escalation
Carbaugh, Chap. 5

Tariffs
Avoiding and postponing tariffs (US)
Production sharing and special treatment
for foreign assembly
Bonded warehouses

Tariffs
Tariff welfare effects
Consumer surplus
The difference between the price buyers would
be willing to pay and what they actually pay
Producer surplus
The revenue producers receive above the
minimum amount required to induce them to
produce a good

Tariff effects
Who pays for import restrictions?
Domestic consumers face increased costs
Low income consumers are especially hurt by
tariffs on low-cost imports
Overall net loss for the economy
(deadweight loss)
Export industries face higher costs for inputs
Cost of living increases
Other nations may retaliate, further
restricting trade
Carbaugh, Chap. 5
12
Reasons for tariffs
Arguments for trade restrictions
Job protection
Protect against cheap foreign labor
Fairness in trade - level playing field
Protect domestic standard of living
Equalization of production costs
Infant-industry protection
Political and social reasons
Carbaugh, Chap. 5
13
Reasons for tariffs
Politics of protectionism
“Supply” of protectionism (trade policy)
depends on:
the cost to society of restricting trade
the political importance of the importcompeting industries
Magnitude of the adjustment costs from free
trade
Public sympathy for those sectors hurt by free
trade
Carbaugh, Chap. 5
14
Reasons for tariffs
Politics of protectionism
“Demand” for protectionism depends on:
The amount of the import-competing industry’s
comparative disadvantage
The level of import penetration
The level of concentration in the affected sector
The degree of export dependence in the sector
Carbaugh, Chap. 5
