Document Summary

Let"s start with the case of no international trade. The market for textiles in isolands consists solely of isolandian buyers and sellers: when an economy cannot trade in world markets, the price adjusts to balance domestic supply and demand. This figure shows consumer and producer surplus in an equilibrium without international trade for the textile market in the imaginary country of isoland. If the world price of textiles is lower than the domestic price, then isoland would become an importer of textiles. By comparing the world price and the domestic price before trade, we can determine whether isoland is better or worse at producing textiles than the rest of the world. Pw (world market price) , pd (domestic price) To analyze the welfare effects of free trade, the isolandian economists begin with the assumption that isoland is a small economy compared to the rest of the world. The isolandians are said to be price takers in the world economy.

Suppose the market for oranges in a small country is closed to international trade. The domestic price is $3 per lb, at which 10,000 lbs are bought and sold in the country, while the world price is $4 per lb. If the country opens up to free trade with the world, the domestic quantity demanded at the world price will be 8,000 lbs, and the domestic quantity supplied at the world price will be 12,000 lbs.

A. Which of the following statements is true?

a. The country will become an importer of oranges because it has a comparative advantage in the production of oranges

b. The country will become an exporter of oranges because it has a comparative advantage in the production of oranges

c. The country will become an importer of oranges because the world has a comparative advantage in the production of oranges

d. The country will become an exporter of oranges because the world has a comparative advantage in the production of oranges

B. At what price (per lb.) will oranges be bought and sold in the country after opening up to trade?

a. $3

b. $4

c. $3.5

C. After opening up to trade, the level of exports/imports for the country will be:

a. 8,000 lbs.

b. 12,000 lbs.

c. 10,000 lbs.

d. 4,000 lbs.

D. How much (in $) is the net gain from trade for this country in opening up to free trade?

Q2. (35 points) The following table shows the output of textile and auto one unit of labor can produce in the U.K. and the U.S.:

	Textiles	Autos
United Kingdom	16	4
United States	6	3

A)Which country has an absolute advantage in textiles and which country has an absolute advantage in autos?

B)What is the autarky price ratio of autos relative to textiles in each country?

C)Which country has a comparative advantage in textiles and which country has a comparative advantage in autos?

D)Which product should each country export?

E)Suppose the United States has 300 units of labor available. Construct the production-possibilities frontier (PPF) and identify the optimal autarky equilibrium (using an indifference curve) for the United States.

F)Suppose the international price is set at 1 auto:3 units of textile and the U.S. decides to completely specialize at producing the product in which it has a comparative advantage. How would the above graph change? Use the graph to show the gains from trade and the export and import quantities. For each unit of export good, how much does the U.S. gain (measured in terms of the other good)?

G)Discussion: At what level of international price ratio will all the benefits from trade accrue to the United States?

1. If we know that Canada exports maple syrup, we can conclude that maple syrup consumers in Canada are worse off than they would be in the absence of trade.

Is the statement true or false?

2. When a country opens up to trade in a good for which it has a comparative advantage, and the country begins to export the good, we can conclude that:

	a.	The domestic price will fall after trade opens up.
	b.	The total surplus for this good will increase as a result of opening up the market to international trade.
	c.	Opening the market to international trade will create a deadweight loss.
	d.	Both buyers and sellers in that country will be better off as a consequence of opening up the market to international trade.
