Essay Questions

1)

Given the input-output relationships in the table below:

Countries

A B

Goods

X 8 4

Y 4 1

(a) Which country has absolute advantage in which good and why?

(b) Which country has comparative advantage in which good and why?

(c) If A is endowed with 8000 hours of labor, how much X will it produce after trade begins? How much Y? Explain.

(d) What is the allowable range on A's wages relative to B's if trade is flowing between these two countries according to comparative advantage?

Answer:

(a) B (A) has absolute advantage in both (neither).

(b) A (B) has comparative advantage in X (Y).

(c) 1000 units of X; 0 units of Y (i.e. complete specialization)

(d) A's wage must range between 1/4 and 1/2 B's wage.

2)

Explain how trade will tend to emerge along the lines of comparative advantage if markets are allowed to work freely.

Answer:

Comparative advantage is determined by autarky prices. Foreign demand will tend to drive up (down) the autarky price of a country's comparative advantage (disadvantage) good, raising short term profits and attracting resources to that industry. These resources come from the import competing comparative disadvantage sector.

3)

Starting from a situation where country A which exports good S and imports good T has a larger trade triangle than country B, explain how the process of reciprocal demand leads to international trade equilibrium.

Answer:

If A has a larger trade triangle than B it wants to trade more than B. Consider the S market. A's desired exports exceed B's desired imports. The price of S must fall. As this occurs, the two trade triangles move toward congruency.

4)

Suppose that workers in A can produce 1 unit of S in 3 hours and 1 unit of T in 9 hours. Suppose further that the relative price of S in B is 2. Graph the PPF for country A. Indicate the exact slope of the PPF. Show how the autarky equilibrium is determined. Illustrate a hypothetical international trade equilibrium, including production and consumption points, and trade volumes for a given (your assumption-be explicit) but permissible value of the international terms of trade.

Answer:

The autarky price of S in A is 1/3, so that must be the slope of its PPF. A has comparative advantage in S, so once trade begins it must completely specialize in S. The international terms of trade must lie between 1/3 and 2.
