Question 24

17) An examination of the Ricardian model of comparative advantage yields the clear result that trade is (potentially) beneficial for each of the two trading partners since it allows for an expanded consumption choice for each. However, for the world as a whole the expansion of production of one product must involve a decrease in the availability of the other, so that it is not clear that trade is better for the world as a whole as compared to an initial situation of non-trade (but efficient production in each country). Are there in fact gains from trade for the world as a whole? Explain.

Answer 24

Answer: If we were to combine the production possibility frontiers of the two countries to create a single world production possibility frontier, then it is true that any change in production points (from autarky to specialization with trade) would involve a tradeoff of one good for another from the world’s perspective. In other words, the new solution cannot possibly involve the production of more of both goods. However, since we know that each country is better off at the new solution, it must be true that the original points were not on the trade contract curve between the two countries, and it was in fact possible to make some people better off without making others worse off, so that the new solution does indeed represent a welfare improvement from the world’s perspective.

6) The pauper labor and the exploitation arguments

A) are theoretical weaknesses that limit the applicability of the Ricardian concept of comparative advantage.
B) are theoretically irrelevant to the Ricardian model, and do not limit its logical relevance.
C) are not relevant because the Ricardian model is based on the labor theory of value.

Question 33

7) If labor productivities were exactly proportional to wage levels internationally, this would

Question 34

8) Many countries in sub-Saharan Africa have very low labor productivities in many sectors, for example in manufacturing and agriculture. They often despair of even trying to attempt to build their industries unless it is done in an autarkic context, behind protectionist walls because they do not believe they can compete with more productive industries abroad. Discuss this issue in the context of the Ricardian model of comparative advantage.

Answer 34

Answer: The Ricardian model of comparative advantage argues that every country must have a comparative advantage in some product (assuming there are more products than countries). However, the Ricardian model is not a growth model, and cannot be used to identify growth modes or linkages.

Question 35

9) In 1975, wage levels in South Korea were roughly 5% of those in the United States. It is obvious that if the United States had allowed Korean goods to be freely imported into the United States at that time, this would have caused devastation to the standard of living in the United States, because no producer in this country could possibly compete with such low wages. Discuss this assertion in the context of the Ricardian model of comparative advantage.

Answer 35

Answer: Regardless of relative wage levels, the United States would be able to provide its populace with a higher standard of living than would be possible without trade. Also, low wages tend to be associated with low productivities.

Question 36

1) The two-country, multi-product model differs from the two-country, two-product model in that, in the former

A) the relative wage ratio will determine the pattern of trade ( which good is exported by which country).
B) which country will export which product is determined entirely by labor productivity data.
C) full specialization is likely to hold in equilibrium.
D) none of the goods are potentially nontraded.
E) domestic relative prices are not relevant.

Answer 36

A) the relative wage ratio will determine the pattern of trade ( which good is exported by which country).

Question 37

2) How does the two-good, two-country version of the Ricardian model differ from the two- country, many-good model in terms of the determination which goods are produced and exported by each country?

Answer 37

Answer: In the two-good-two-country version of the Ricardian model, comparative advantage is totally determined by physical productivity ratios. Changes in wage rates in either country do not change physically determined comparative advantages, and therefore cannot affect which product will be exported by which country.

However, when there are more than two goods in the two-country model, changes in wage rates in one or the other country can in fact determine which good or goods each of the countries will export. The physical productivity definition of comparative advantage employed in the two-good model becomes ambiguous. Instead, changes in relative wage rates will alter international competitiveness along the “chain of comparative advantage.”

Question 38

1) Assume that transportation costs are especially high for Widgets in the two-country, two- product Ricardian model, and Country A enjoys a comparative advantage in Widgets, then

A) country B must also enjoy a comparative advantage in Widgets.

Question 40

B) The existence of nontraded goods results in a high degree of specialization among countries.
C) International trade has no impact on income distribution.
D) The unimportance of economies of scale as a cause of trade.
E) Companies tend to export goods in which they have a relatively high level of productivity.

Answer 40

E) Companies tend to export goods in which they have a relatively high level of productivity.

Question 41

2) When compared with China, the growth of clothing exports originating in Bangladesh clearly illustrates the difference between absolute and comparative advantage. Discuss and explain.

Question 45

fig. 3R
1) Use the information in the table below to answer the following questions.

(a) Does either country have an absolute advantage in the production of wheat or beef? Explain.
(b) What is the opportunity cost of wheat in each country?
(c) What is the opportunity cost of beef in each country?
(d) Analyze comparative advantage and opportunities for trade between the U.S. and Argentina.

Answer 45

Answer:
(a) The U.S. has an absolute advantage in the production of both wheat and beef because labor productivity in the U.S. exceeds labor productivity in Argentina for both products.

(b) In the U.S., the opportunity cost of wheat is 100/300 or 0.33 units of beef. In Argentina, the opportunity cost of wheat is 20/20 or 1.0 unit of beef.
(c) In the U.S., the opportunity cost of beef is 300/100 or 3.0 units of wheat. In Argentina, the opportunity cost of beef is 20/20 or 1.0 unit of wheat.
(d) The U.S. has a comparative advantage in wheat production and Argentina has a comparative advantage in beef production. If the U.S. can trade wheat to Argentina at a rate of more than 0.33 units of beef per unit of wheat, then the U.S. will benefit. If Argentina can trade beef to the U.S. at a rate of more than one unit of wheat per unit of beef, then Argentina will benefit.

(d) Analyze comparative advantage and opportunities for trade between the U.S. and Argentina.

Answer 46

Answer:

(b) In the U.S., the opportunity cost of wheat is 100/200 or 0.5 units of beef. In Argentina, the opportunity cost of wheat is 80/20 or 4.0 units of beef.
(c) In the U.S., the opportunity cost of beef is 200/100 or 2.0 units of wheat. In Argentina, the opportunity cost of beef is 20/80 or 0.25 units of wheat.
(d) The U.S. has a comparative advantage in wheat production and Argentina has a comparative advantage in beef production. If the U.S. can trade wheat to Argentina at a rate of more than 0.5 units of beef per unit of wheat, then the U.S. will benefit. If Argentina can trade beef to the U.S. at a rate of more than 0.25 unit of wheat per unit of beef, then Argentina will benefit.
