Ch 5 – Tariffs
“Free trade, one of the greatest blessings which a
government can confer on a people, is in almost every country
unpopular.”Lord Thomas Macauley
Ch 5 - Tariffs
Tariff - Tax, or duty, levied on a product when it crosses a nation’s boundaries.
Import Tariff Most common Imposed on imported goods
Export Tariff Imposed on exported goods Unconstitutional in US
Protective Tariff Designed to protect domestic producers from import
competition Not total prohibition, just an edge for domestic
industries Revenue Tariff
Imposed specifically to raise tax revenues
Ch 5 - Tariffs
Methods of Tariff Application1. Specific Tariff
Fixed dollar amount per physical unit of product. Easy to administer ex, $5000 tariff for every television, regardless of the
cost of the TV.
Problems: Degree of protection will vary inversely with
import prices. Higher priced imports will pay a lower % of tariff
on goods. Will discourage lower priced goods more than
higher priced goods.
Ch 5 - Tariffs
Methods of Tariff Application2. Ad Valorem Tariff
Fixed percentage of value of product. Can distinguish small differences in quality as
reflected by price of good. Constant degree of protection for domestic
producers during changing prices.
3. Compound Tariff Used for goods with raw materials subject to tariffs. Combination of specific tariff for protection in raw
material industry, and ad valorem for final product.
Ch 5 - Tariffs
Methods of Tariff Valuation1. Free on board (FOB)
Tariff applied to product’s value as it leaves the exporting country.
2. Cost-Insurance-Freight (CIF) Based on commodity’s total value, including
transport costs.
Effective Rate of Protection A nominal tariff rate gives a general idea of level of
protection, but a final good can include domestic AND imported components.
Degree of protection granted by a tariff reflects extent to which domestic price can rise above foreign.
Need to know effective rate to determine actual degree of protection.
Effective rate = total increase in domestic production activities (value added) that a tariff structure makes possible (how much more expensive the domestic good can be).
Ch 5 - Tariffs
Effective Rate of Protection
Domestic radio industry uses imported components to assemble radios.
20% of radio’s final value comes from domestic assembly (value added)
Components are imported duty-free.
Costs are the same in both countries.
Foreign radio’s pre-tariff price = $100.
Nominal tariff on imported radios = 10%.
Assume:

When inputs enter a country at a low tariff rate, and final good is protected at a high tariff rate, the effective rate of protection tends to be high (nominal rate understates degree of protection).
BUT, if tariff on inputs is greater than tariff on final good, the nominal rate would overstate the effective rate.

Which will prevail? Depends on whether a nation wants to protect the suppliers of raw materials or producers of the end product.
Effective Rate of ProtectionCh 5 - Tariffs
Tariff EscalationTariff structure where a nation tends to have higher nominal rates for each subsequent stage of production (ex, raw materials have low nominal tariffs while end products have high nominal tariffs).
Nominal Rate
Raw Materials Final GoodsStages of Production
Tariff Escalation
Ch 5 - Tariffs
Industrialized nations tend to engage in tariff escalation.
Tariff escalation encourages developing nations to specialize in raw materials, and discourages entry into higher stages of production.
If nations push for lower tariffs for their raw products, the effective rate is magnified for the producers of the final product (manufacturing sector), worsening chance of entry into higher stages of production for the developing nations.
Production Sharing / Offshore Assembly
Ch 5 - Tariffs
Production sharing occurs when different phases of a product’s manufacture are performed in more than one country.
Example, US makes electronic components, ships them to Mexico for assembly with lower labor costs, then the final product is sent back to the US for distribution.
Benefits Provides a way for domestic manufacturers of goods with
labor-intensive phases to take advantage of lower costs abroad while maintaining competitiveness and market share domestically.
Easier penetration into foreign markets where trade barriers restrict direct export of the final product.
Production Sharing / Offshore Assembly
Ch 5 - Tariffs
OAP (offshore-assembly provision) provides favorable treatment for goods assembled abroad from US-manufactured components.
When a final good comes into the US, the tariff is applied only to the portion of the good that originated elsewhere.
Incentive for US producers to seek cheaper off-shore labor for assembly process.
Encourages countries that want to export to the US to buy components from US.
Postponing Import Duties
Ch 5 - Tariffs
Bonded Warehouses• Customs facility where imported goods can be
stored.• No tariff is levied until goods leave the warehouse.• Importer can avoid lump costs until goods are sold.
Foreign Trade Zones (FTZ’s)• Seaports, inland distribution points.• Manufacturing process can take place.• Tariff is deferred until final good is shipped out of
the FTZ.• No tariff on scrap or waste.

Large Nation Model• Nation’s imports make up a relatively large portion of
world market supply• Nation is a price maker, large enough to impact the
world market.• If US imposes tariff, price increases for domestic
consumers, quantity demanded falls. May lead to exporting nation lowering prices to US to limit loss of sales.
• Burden of tariff is shared between consumers and foreign producers.
• Terms of trade may improve for importing nation with price reduction. Therefore, large nation can make itself better off with appropriate tariff policy.

Arguments for Trade Restrictions
Ch 5 - Tariffs
Job Protection
Argument:Cheap foreign goods undercut domestic production, resulting in loss of domestic jobs.
Flaw:Ignores link between importing and exporting industries.
Job losses are more conspicuous than gains.
Trade barriers raise employment in protected industries, and in industries that are primary suppliers.
BUT job losses occur in industries that purchase protected goods, costs passed along to consumers, reducing sales.
“Exporters pay for import tariffs.”
Arguments for Trade Restrictions
Ch 5 - Tariffs
Protection Against Cheap Foreign Labor
Argument:US wages are high relative to other countries. Tariffs should make up for the difference between labor costs to protect domestic jobs.
Flaw:Ignores link between efficiency, wages, and unit costs.
If domestic labor is more productive than cheaper foreign labor, domestic labor costs may still be competitive.
Wages are based on MRPL (marginal revenue product of labor).
Arguments for Trade Restrictions
Ch 5 - Tariffs
Maintenance of Domestic Standard of Living
Argument:Tariffs maintain a high level of income and unemployment, stimulate domestic activity, raising standard of living.
Flaw:Assumes first two arguments are valid, and ignores redistribution of gains resulting from tariffs.
A tariff that improves standard of living in one country does so at the expense of other countries.
Nations adversely affected will retaliate, resulting in lower welfare for both nations.
“Beggar-thy-neighbor” policies – tariffs designed to enhance standard of living at the expense of trading partners.
Arguments for Trade Restrictions
Ch 5 - Tariffs
Infant Industry Argument
Argument:Mature foreign businesses can drive young domestic businesses out by being more efficient. Nations should temporarily shield new industries until they have developed enough to compete.
Flaw:Industrialized nations typically don’t have infant industries.
Protective tariffs are difficult to remove once in place.
Which industries can realize comparative advantage and merit protection?
May be valid for developing nations to change their comparative advantage position.

Quota – Quantitative restriction
Import Quota Restriction on quantity of goods that can be imported during
specific time period. Generally limits quantities below free trade level (much like
price ceilings). Import quotas on manufactured goods outlawed by WTO.
Current quotas usually agricultural. Global Quota
Specified amount imported each year, but origin not specified. Example, 10 million pounds of sugar per year, no matter the
country of origin. Selective Quota
Allocations to specific countries Example, Canada’s 4 million lbs + Mexico’s 3 million lbs +
Brazil’s 3 million lbs = 10 million total.
Ch 6 – NTB’s
Quota – Quantitative restriction
Welfare Effects Supply side restriction Loss of consumer surplus from increase in domestic and
imported price (same welfare concept as tariffs) Same deadweight losses (protective effect and consumption
effect) Surplus transferred from consumers to producers.
Revenue Effect Not a tariff, so revenue doesn’t automatically go to the
government. Will accrue to whomever has market power. If domestic buyers organize to buy goods at lower than market
price, gain will go to them in form of profits. If foreign producers organize to sell to domestic distributors at
already heightened price, they will accrue profits. Government CAN still accrue gains from revenue effect by
selling import licenses.
Ch 6 – NTB’s
Quota – Quantitative restriction
Government Can Sell Import Licenses Quotas push domestic price above world price.
Profits can be enjoyed by domestic retailers if they buy low in world market and sell high in domestic market.
Retailers would likely pay for the right to import a portion of the limit amount of goods.
By auctioning licenses to import, government can transfer some or all of the gains to government revenue.
Competition for the licenses would push the license price up to the point that eliminates all of the retailer profit and transfers to government revenue.
This makes quota outcomes much like tariffs.
Ch 6 – NTB’s
Tariff-Rate Quota (aka 2-tier tariff)
Certain number of goods are imported at one tariff rate, any quantity above that imported at a higher rate.
Example: up to 5 tons of sugar can be imported at a 10% tariff, anything above 5 tons will be imported at 20% tariff rate.
Quota in this case is 5 tons.
Within-quota rate = 10%
Over-quota rate = 20%

Orderly Marketing Agreements (OMA’s)
Agreement negotiated between trading partners.
Usually takes form of Voluntary Export Restraints (VER’s), voluntary quotas.
These deals usually struck to avoid more restrictive barriers.
Revenue Effect Under standard import quota, revenue accrues to side with
most market, or bargaining, power.
With export quota, foreign exporter captures revenue because the restriction is purely supply side, drives up price.
For this reason, exporters prefer negotiating their own export restrictions rather than facing levies of importing countries.

Domestic Subsidies Granted to import-competing industries. Subsidies increase producer surplus, but also have
deadweight loss to society. Usually, loss of welfare is less for subsidy than tariffs or
quotas.• Tariffs and quotas distort choices as consumers respond to
higher prices.• Subsidies don’t increase prices for consumers so there is no
distortion of consumer choices Subsidies have to be paid for ultimately from tax revenues, so
burden is widespread, difficult to pinpoint.
Subsidies
Can take form of cash, tax concessions, insurance perks, low interest loans, etc.
Ch 6 – NTB’s
Export Subsidies Lowers price of goods in world market to increase
competitiveness.
Worsens terms of trade because price paid by foreign consumers is less than domestic, but export volume increases.
Net effect depends on elasticity of good. (remember elasticity?)
