First Midterm Examination

September 24, 1997

 

First Part (15 point questions)

For each of the following statements, state whether you agree or disagree with the statement, and explain why. It is not sufficient to simply write "True" or "False"; your reason is as important, if not more so.

1. If Consumption, Investment, Government Spending and Net Exports go up, but hours of work do not, we will see a rise in GDP but not in National Income.

False. We will see a rise in GDP but that also means a rise in income. The fact that hours of work has not changed is just a red herring.

2. In East Vhalla, per capita GDP is 14,350 Tiblets (T ), while per capita GDP is 175,800 Umlauts (ö ) in West Vhalla. Since today’s Wall Street Journal showed that 1 T = 10 ö it is clear that West Vhalla has the higher standard of living.

Disagree. Whose relative prices are you using to evaluate the consumption? It is not clear what the citizens of the two countries consume.

3. If apples and bananas are substitutes, a decrease in the demand for apples means that there will be a movement up the demand curve for bananas.

Disagree. A decrease in the demand for apples is likely to lead to a lower price for apples, and that will mean an increase in the demand curve for bananas, but not a movement up the demand curve. In fact the increase in the demand for bananas is likely to lead to a higher price for bananas, and that will lead to a movement down the demand curve.

4. While most supply curves are upward sloping, the long run Aggregate Supply Curve is a vertical line.

True. Why should the price level affect the productive capacity of the economy?

Second Part (20 point questions)

1. East and West Burp, two small adjoining countries, both make bread and butter. East Burp has twenty workers, who can each make a pound of butter per day or a loaf of bread per day. West Burp has 30 workers, who can each produce a pound of butter per day or a 1.5 loaves of bread per day.

a. Using the following graphs draw the production possibility curves for East and West Burp Be sure to label your axes and indicate the scale.

 

b. Now draw the combine production possibility curve for East and West Burp. Be sure to label your axes and indicate the scale.

c. In which product does East Burp have a comparative advantage? West Burp? Explain your reasoning.

East Burp has a comparative advantage in bread, while West Burp has a comparative advantage in butter. Why? Because East Burp must give up only a pound of butter to get a loaf of bread, while West Burp must give up a 1.5 pounds.
