Determinants of Trade
Equilibrium without trade Only domestic buyers and sellers
Domestic price in the textile market will balance supply and demand
Total Benefits Consumer Surplus
Producer Surplus
Determinants of Trade
A new leader is elected to Latveria who is interested in pursuing trade. A committee of economists is organized to determine the following:
If the government allows trade, what will happen to the price of textiles and the quantity of textiles sold in the domestic market?
Who will gain from trade, who will lose, and will the gains exceed the losses?
Should a tariff (a tax on imported textiles) be part of the new trade policy?
Determinants of Trade
The first issue is to decide whether Latveria should import or export textiles. The answer depends on the relative price of
textiles in Latveria compared with the price of textiles in other countries.
Definition of world price: the price of a good that prevails in the world market for that good.
Compare domestic price with world price Determine who has comparative advantage
If domestic price < world price
Export the good
The country has comparative advantage
If domestic price > world price
Import the good
The world has comparative advantage
Note that the domestic price represents the opportunity cost of producing textiles in Latveria, whereas the world price represents the opportunity cost of producing textiles abroad.
Competitive Markets
Textiles are generally part of a competitive market there are many firms in the
market, none of which is large in terms of sales
Firms can enter and exit the market easily
Each firm in the market produces and sells a nondifferentiated or homogeneous product
All firms and consumers in the market have complete information about prices, product quality, and production techniques
Winners and Losers from Trade
Latveria will be price takers in textile world market (must buy or sell at that price)
If the world price is higher than the domestic price, Latveria will export textiles.
Once trade is allowed Domestic price rises to = world
price
Domestic quantity supplied > domestic quantity demanded
The difference = exports

With international trade: Consumer surplus ______
(increases/decreases)
Producer surplus _______(increases/decreases)
Total surplus ________(increases/decreases)
The economic well-being of the country ______(rises/falls).
Importing Country Meanwhile in Wakanda…
Wakanda’s domestic equilibrium price for textiles before trade is above the world price for textiles
Once trade is allowed… Domestic price ____ (rises/drops) to = world price
Domestic quantity supplied ____ ( </>) domestic quantity demanded
The difference = _______ (imports/exports)

Tariffs and Quotas
Tariff
Tax on goods produced abroad and sold domestically
Free trade
Domestic price = World price
Tariff on imports
Raises domestic price above world price
By the amount of the tariff

Tariffs
The effects of a tariff Price rises by _______________
Domestic quantity demanded ______ (increases/decreases)
Domestic quantity supplied ________(increases/decreases)
_________(Increases/decreases) the quantity of imports
Moves the domestic market _____(closer/farther away) to its equilibrium without trade
Domestic sellers are ______(better off/worse off)
Domestic buyers are ______(better off/worse off)
Consumer surplus is ______ (bigger/smaller)
Producer surplus is ______(bigger/smaller)
Government tax revenue is ______ (bigger/smaller)
Total Surplus is _______(bigger/smaller)
Import Quotas: Another Way to Restrict Trade
An import quota is a quantitative limit on imports of a good.
Mostly has the same effects as a tariff: Raises price, reduces quantity of imports.
Reduces buyers’ welfare.
Increases sellers’ welfare.
A tariff creates revenue for the govt. A quota creates profits for the foreign producers of the imported goods, who can sell them at higher price.
Or, govt could auction licenses to import to capture this profit as revenue. Usually it does not.

Summary: The Welfare Effects of Trade
Whether a good is imported or exported, trade creates winners and losers. But the gains exceed the losses.
Other benefits of international trade Consumers enjoy increased variety of goods.
Producers sell to a larger market, may achieve lower costs by producing on a larger scale.
Competition from abroad may reduce market power of domestic firms, which would increase total welfare.
Trade enhances the flow of ideas, facilitates the spread of technology around the world.

Then Why All the Opposition to Trade?
Recall one of the Ten Principles from Chapter 1: Trade can make everyone better off.
The winners from trade could compensate the losers and still be better off.
Yet, such compensation rarely occurs.
The losses are often highly concentrated among a small group of people, who feel them acutely.
The gains are often spread thinly over many people, who may not see how trade benefits them.
Hence, the losers have more incentive to organize and lobby for restrictions on trade.

Arguments for Restricting Trade
1. The jobs argument
Trade destroys jobs in industries that compete with imports.
Economists’ response:
Look at the data to see whether rising imports cause rising unemployment…

Arguments for Restricting Trade
2. The national security argumentAn industry vital to national security should be protected from foreign competition, to prevent dependence on imports that could be disrupted during wartime.
Economists’ response:Fine, as long as we base policy on true security needs. But producers may exaggerate their own importance to national security to obtain protection from foreign competition.

3. The infant-industry argumentA new industry argues for temporary protection until it is mature and can compete with foreign firms.
Economists’ response:Difficult for govt to determine which industries will eventually be able to compete and whether benefits of establishing these industries exceed cost to consumers of restricting imports. Besides, if a firm will be profitable in the long run, it should be willing to incur temporary losses.

Arguments for Restricting Trade
4. The unfair-competition argument
Producers argue their competitors in another country have an unfair advantage, e.g. due to govt subsidies, regulations
Economists’ response:Great! Then we can import extra-cheap products subsidized by the other country’s taxpayers. The gains to our consumers will exceed the losses to our producers.

5. The protection-as-bargaining-chip argument
Example: The U.S. can threaten to limit imports of French wine unless France lifts their quotas on American beef.
Economists’ response:Suppose France refuses. Then the U.S. must choose between two bad options: A) Restrict imports from France, which
reduces welfare in the U.S.B) Don’t restrict imports, which reduces
U.S. credibility.

Trade Agreements A country can liberalize trade with
unilateral reductions in trade restrictions
multilateral agreements with other nations
Examples of trade agreements: North American Free Trade Agreement
(NAFTA), 1993 General Agreement on Tariffs and
Trade (GATT), ongoing Successfully reduced the average tariff
among member countries from about 40% to 5%
Enforced by the WTO 153 countries; 97 % of world trade
World Trade Organization (WTO), est. 1995, enforces trade agreements, resolves disputes
