Trade Policy Analysis
CHAPTER 6

Introduction
Reasons to expect landowners in Japan might
oppose the import of rice from another country
Opposition to imports exists despite overall gains to
Japan from these imports
Trade policy analysts and international affairs
professionals are often called upon to assess
impacts of government interventions in international
trade
Purpose of chapter is to understand how the
assessments are made

and Trade in the Rice Market

Absolute Advantage Revisited
In moving from autarky to trade in Figure 6.1,
there is a reduction in domestic quantity
supplied in Japan
Japanese rice-producing firms would lobby
Japanese government to oppose decrease in
domestic quantity supplied
• Demand protection from Vietnam exports
Protective policies are widespread in world
economy

Trade Policy Measures
A country can grant import protection to a
sector of its economy in form of either
Tariffs
• Tax on imports
Specific tariff is a fixed tax per physical unit of the import
Ad valorem tariff is a percentage tax applied to value of
import
Non-tariff measures
Governments employ both types of tariffs

Non-Tariff Measures
An inclusive category of many kinds of trade policy measures including
Prohibitions and quantitative restrictions (import quotas) on imports
Tariff rate quotas
• Lower (higher) tariff for levels of imports within (above) the quota
Trigger-price mechanisms
• Market floor prices that “trigger” government interventions to curtain imports
Technical barriers to trade
• Support health and safety concerns—may be legitimate but can be a disguised
form of import protection
Anti-dumping duties—charges imposed on imports deemed by imposing
government to have been sold at “less than fair value” by exporter
Countervailing duties—tariff-like charges imposed on imports deemed by
imposing government to have been “unfairly” subsidized by exporting
country government

A Tariff
For our graphical analysis in this chapter, it is much
simpler to consider a specific tariff
Basic results also apply to an ad valorem tariff
A tariff increases domestic price of imported
product above world price
In the case of Japanese rice, domestic price is many
times larger than world price
• Causes an increase in Japan’s production of rice which is desired
effect from Japanese rice farmers
Domestic consumption of rice falls
Imports fall

Tariff Effects
Welfare and revenue effects also occur from the
tariff
Consumer surplus of Japanese households fell
Japanese rice consumers are paying more and
consuming less
Producer surplus of Japanese firms has increased
Japanese rice producers are receiving more for their
product and producing more
Japanese government is receiving revenue from
import tax

Net Welfare Effect
Summarizes welfare impact of policy for the
country as a whole
From an economic standpoint, tariff hurts
Japanese society as a whole
Although it benefits producers and government,
losses imposed on consumers outweigh benefits
Reinert/Windows on the World Economy, 2005
10
Terms of Trade Effects
When Japan imposes a tariff on its imports
from Vietnam, amount of these imports
decreases
As Japan’s imports of rice decrease, there will be
excess supply in the world market for rice
• Will cause the world price to fall
• Since Japan is importing rice, this is a good thing for
this country

A Quota
Import quota—a quantitative restriction on
imports
Type of non-tariff measure
A quota results in a shortage of a good
relative to initial situation without quota,
causing price of good to rise
Known as quota premium
Consumer surplus falls and producer surplus
increases
Reinert/Windows on the World Economy, 2005

Figure 6.4 A Quota on Japan’s
Rice Imports

14
A Quota
Policy usually administered via a system of import
licenses
Quota has restricted supply of import licenses
Extra value of the right to import an amount of a
good
Known as quota rents
• Who receives rents depends on how quota licenses are allocated
Import licenses are allocated to domestic importers
Quota rents accrue to importers, so they remain within the
country
A gain to Japan
Import licenses are allocated to foreign exporters
Quota rents accrue to exporters, so they leave the country
A loss to Japan
Reinert/Windows on the World Economy, 2005
15
A Quota
Net welfare effect of the quota is just like a specific
tariff
In the case of import licenses allocated to foreign
exporters this represents a transfer from domestic
consumers to these foreign exporters
Does not result in a net loss of zero, because loss to
consumers is not offset by a gain to domestic importers
Net welfare effect is gain to firms less loss to
consumers
In this case quota is worse than a tariff
Reinert/Windows on the World Economy, 2005

Quota Decision
Suppose you were a government official
administering quota policy
Which alternative would you choose?
• A quota allocated to domestic importers or quota allocated to
foreign exporters?
Probably quota allocated to domestic importers
Has smaller welfare loss
However governments often choose a foreign
allocated quota. Why?
They are uninformed about economic implications of their
choices
Political considerations cause such a choice

Summary of Trade Policies
Tariff
Unambiguous net welfare loss due to consumer surplus loss
outweighing gains in producer surplus and government revenue
Tariff with terms of trade effects
Ambiguous net welfare effect due to terms of trade gain (fall in world
price) potentially outweighing efficiency loss
Domestic-allocated quota
Unambiguous net welfare loss due to consumer surplus loss
outweighing gains in producer surplus and quota rents
Foreign-allocated quota
Unambiguous net welfare loss that exceeds that of domesticallocated quota case

Comparative Advantage Models
In many instances effects of trade policies go
beyond a single sector
Protecting a large sector such as automobiles can
draw resources from other sectors into the
protected automobile sector
Perhaps workers in metal furniture sector will move into
automobile sector as it expands under protection
In these cases, trade policy analysts turn to models
of comparative advantage
Analyzes more than one sector simultaneously
• Much more complicated than absolute advantage models
