Document Summary

Countries can gain from trade if each exports the goods in which it has a comparative advantage: this chapter tries to see where the gains come from and who gets them. World price (pw) the price that prevails in the world markets. Domestic price (pd) the price without trade. If pd < pw: country has comparative advantage in the good. If pd > pw: country does not have comparative advantage. Price taker its actions have no effect on pw: usually related to a small economy, when a small economy engages in free trade, pw is the only relevant price. Example: country that exports soybeans: w/o trade. Total surplus = a + b +c: w/ trade. Ps = b + c + d (producers benefit) Total surplus = a + b + c + d. Part d is the area where the producers are able to sell their goods to buyers from other countries. Example: trade of tvs: pd = .

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?

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.

2. Winners and losers from free trade

Consider the market for meekers in the imaginary economy of Meekertown. In the absence of international trade, the domestic price of a meeker is $21. Suppose that the world price for a meeker is $22. Assume that Meekertown is too small to influence the world price for meekers once they enter the international market.

If Meekertown allows free trade, then it will meekers.

Given current economic conditions in Meekertown, complete the following table by indicating whether each of the statements is true or false.

Statement	True	False
Meekertownian consumers are worse off under free trade than they were before.
Meekertownian producers are worse off under free trade than they were before.

True or False: When a country is too small to affect the world price, allowing for free trade will always increase total surplus in that country, regardless of whether it imports or exports as a result of international trade.

True

False
