ch07 Import Tariffs and Quotas Under Perfect Competition - Spring 2025 (2)
Chapter Overview
Course: ECON 335: International Economy
Topic: Import Tariffs and Quotas Under Perfect Competition
Semester: Spring 2025
Introduction to Trade Policies
Tariff Example:
Announced by President Barack Obama on September 11, 2009, a 35% tariff on Chinese tire imports.
Expired on September 27, 2012.
Trade Policy Definition:
Government actions aimed at influencing international trade volumes.
Rationale for Trade Policy:
Gains from trade are unevenly distributed, leading industries and unions to pursue policies that limit losses or enhance gains.
Types of Trade Policies:
Import tariffs (taxes on imports)
Import quotas (quantity restrictions on imports)
Export subsidies
Examination of Trade Policies
Focus: Effects of tariffs and quotas in perfectly competitive industries.
Tariffs:
Most commonly used trade policy; examined in detail.
Import Quotas:
Definition: Limits on the quantity of a good imported from foreign countries.
Historical Context of the World Trade Organization (WTO)
Post-WWII Discussions:
Allied countries aimed to address trade barriers and exchange rate instability.
1947 Establishment:
General Agreement on Tariffs and Trade (GATT) was formed to minimize trade barriers.
Key Provisions of GATT:
Equal tariff extension to all WTO member nations.
Tariffs can counter unfair practices like dumping.
Limitation on restrictiveness of import volumes.
Requirement to declare export subsidies.
Conditional tariff increases allowed.
Allowance for regional trade agreements, such as free-trade areas and customs unions.
Key Provisions of GATT
Article I: Most-Favored-Nation (MFN) Treatment
Article VI: Anti-Dumping and Countervailing Duties
Article XI: Elimination of Quantitative Restrictions
Article XVI: Subsidies
Article XIX: Emergency Actions on Imports
Article XXIV: Regulations on territory and customs unions/free-trade areas
Consumer and Producer Surplus Analysis
Figure 7-1: Explains consumer surplus as the difference between the price consumers are willing to pay and the actual market price.
Consumer surplus is demonstrated graphically as the area under the demand curve and above the price.
Trade Dynamics
Figure 7-2: Depicts the impact of trade on domestic demand, supply, and consumer surplus relative to world price.
No-trade equilibrium vs. trade at world price leading to imports.
Gains from trade visualized through changes in consumer surplus and welfare.
Tariff Effects for Small Countries
Figure 7-4: Illustrates the impact of tariff application on prices and quantities.
Price increment leads to shifts in supply and demand.
Welfare Implications:
Tariffs decrease consumer surplus while increasing producer surplus and generating government revenue.
Calculation of deadweight loss associated with tariffs.
Why Tariffs are Commonly Applied
Revenue Generation:
Especially vital for developing countries reliant on tariffs as a source of government revenue
Political Dimensions:
Concentrated benefits to specific firms/industries versus dispersed costs to consumers.
Import Quota System
Post-2005 Context:
Abolishment of Multifibre Arrangement (MFA) which restricted textile and apparel imports.
Quota Examples:
EU banana import quotas favoring former colonies over Latin America.
U.S. sugar import quotas still in place.
Import Quota Mechanisms
Price Impact:
Comparison of price changes and quantities under quotas.
Market Allocation:
Various allocation methods of quota rents, including:
Allocating to home firms.
Rent-seeking behavior.
Government auctions.
Voluntary export restraints (VER).
Quantifying Costs of Import Quotas
Evaluating annual costs in terms of deadweight losses and quota rents via historical data.
Multifibre Arrangement (MFA) Aftermath
Impact of Expiration:
Rapid growth in Chinese textile and apparel exports post-MFA.
Welfare Loss:
Costs incurred by the U.S. due to non-auctioning of quota licenses leading to significant quota rent exports.
Market Shifts:
Increase in demand for lower-priced items post-MFA as prices for textiles fell.
