G. Which nation has the comparative advantage in beer? In cigarettes?

H. Assume each nation is autarkic and producing and consuming that amount of beer and cigarettes that is at the midpoint of the PPF. Identify this point, and the respective quantities, on each nation's PPF. Label this point "Point A."

I. Assume each nation specializes 100% in the product in which it has the comparative advantage. Label this point "Point B."

J. Assume the nations trade with each other. Identify one possible mutually acceptable price at which beer and cigarettes trade for one another. Make sure you write "one mutually acceptable price of 1 beer is # cigarettes" which implies the price of "1 cigarette is # beer."

3. Nation 1 can produce Y tons of product A per worker per day and Z tons of product B per worker per day. Nation 2 can produce G tons of A per worker per day and H tons of product B per worker per day (Y, Z, G, H are numbers of your choice).

A. Which nation has an absolute advantage in A? In B?

B. In the Nation 1, what is the opportunity cost of A (in terms of B)? What is the opportunity cost of B?

C. In Nation 2, what is the opportunity cost of A (in terms of B)? What is the opportunity cost of B?

D. Which nation has a comparative advantage in A? Why? In B? Why?

E. If the nations choose to trade, what is one potentially mutually agreeable price for A? For B?

4. Germany has the following demand for garden gnomes: P = 200 - Q and the following domestic supply of garden gnomes: P = 50 + Q.

A. Assume Germany is autarkic, graph the demand and supply functions and determine the equilibrium price and quantity.

B. Determine the amount of consumer surplus, producer surplus, and gains to trade.

C. Assume Germany can import similar garden gnomes from Poland at a free-trade price of $50. What is domestic quantity supplied? Domestic quantity demanded? The amount of imports? (Assume Germany is a "small" nation).

D. Germany applies a $50/gnome tariff on Polish made gnomes. What is domestic quantity supplied? Domestic quantity demanded? The amount of imports?

E. Calculate the loss of consumer surplus as a result of the tariff.

5. When a tariff is applied to a foreign product consumed by a "small" nation, the tariff results in a loss of consumer surplus that can be broken out into four separate areas (a, b, c, and d).

A. Describe in detail what each of the four areas represents.

B. Identify which areas are transfers and which represent deadweight losses.

G. On page 62, what kind of tariff is Dave talking about?

8. During the time of Abraham Lincoln's presidency the trans-continental railroad was nearing completion. When he was advised to buy iron rails from Britain to finish the job, Lincoln said: "It seems to me that if we buy the rails from England, then we've got the rails and they've [Britain] got the money. But if we build the rails here, we've got our rails and we've got our money." What is the flaw in Lincoln's logic?
