Essay Questions
1. It is argued that small countries tend have more open economies than large ones.
Is this empirically verified? What are the logical underpinnings of this argument?
Answer: Yes. They do not have sufficient resources to satisfy consumption needs; and
also do not have a sufficiently large market to enable their industries to avail themselves
of scale economy possibilities.
Another answer would rely on a location argument. Assume that the "natural" market for
any given plant is a circle with a radius of n miles with the plant at its center. Assuming
that the production plants are located randomly throughout the country, then the
probability that the typical circular market will encompass some foreign country is
greater the smaller is the country.
2. It is argued that if a rich high wage country such as the United States were to
expand trade with a relatively poor and low wage country such as Mexico, then
U.S. industry would migrate south, and U.S. wages would fall to the level of
Mexico's. What do you think about this argument?
Answer: The student may think anything. The purpose of the question is to set up a
discussion, which will lead to the models in the following chapters.
3. Some patterns of international trade are easier to explain than others. Give several
examples and explain.
Answer: Historical circumstance can explain some patterns such as the relatively large
trade flows from West Africa to France. The relatively sparse trade between countries
within South America seems curious.
4. International trade tends to prove that international trade is beneficial to all
trading countries. However, casual observation notes that official obstruction of
international trade flows is widespread. How might you reconcile these two
facts?
Answer: Like question 2, this is meant to allow students to offer preliminary discussions
of issues, which will be explored in depth later in the book.

9. International Trade theory is one of the oldest areas of applied economic policy
analysis. It is also an area for which data was relatively widely available very
early on. Why do you suppose this is the case?
Answer: In ancient times, public finance was not well developed. Most of the
population was not producing and consuming within well-developed market economies,
so that income and sales taxes were not efficient. One of the most convenient ways for
governments to obtain resources was to set up custom posts at borders and tax. Hence
international trade was of great policy interest to princes and kings, as was precise data of
their main tax base.12
Quantitative/Graphing Problems
1. The figure above is the Production Possibility Frontier (PPF) of Baccalia, where
only two products are produced, clothing and wine. In fact Baccalia is producing
on its PPF at point A. By and large the people of Baccalia are content, as both
their external and internal needs for warmth are satisfied in the most economically
efficient manner possible, given their available productive resources (and known
technology). How much wine is being produced? How much cloth? If a person
in this country wanted to purchase a liter of wine, what would be the price he or
she would have to pay?
Judging from what you learned in the previous paragraph, can you indicate at
which point (if at all) the Community Indifference Curve is tangent to the
Production Possibility Frontier? Explain your reasoning.
Answer:
6 million liters of wine are being produced.
3 million square yards of cloth are being produced.
The price of 1 liter of wine is one half of a square yard of cloth.
The tangency is at point A. We know this because otherwise the country would
not be producing at the point of maximum economic efficiency.13
2. One day, Baccalia joined the WTO and joined the Global Village. They
discovered that in the LWE (London Wine Exchange), 1 liter of wine is worth 1
square yard of cloth. What is the logical production point they should strive for?
Answer: 10 million liters of wine.
3. They wish to enjoy to the fullest from the gains from trade, but are not willing to
give up imbibing even one drop of wine from the 6 million liters they consumed
in their original autarkic state. If their new consumption point is a point we shall
designate as point b, describe where this point would be found.
Answer: Vertically above point a
4. Where is the Community Indifference Curve family of curves tangent to their new
Consumption Possibility Frontier?
Answer: At point b.
5. How can you prove that Baccalia has in fact gained from the availability of trade,
and that their new situation is superior to the pre-trade situation (with which they
were quite content)?
Answer: The country was consuming at point a before trade. It is now consuming at
point b with trade. Point b represents a superior welfare combination of goods as
compared to point a, since at b the country has more of each of the goods.14
