a)  Compute the U.S. GDP for 1998 using the flow-of-expenditures approach.

b)  Compute the U.S. GDP for 1998 using the flow-of-earnings approach.

c)  Compute the U.S. GNP for 1998.

d)  Compute the U.S. NNP, NI, PI, and DI for 1998.

 

2. a) Use aggregate supply and demand analysis to explain the macroeconomic consequences of the devaluation of the Real for the Brazilian economy.

b) Assume that President Cardoso says that he wants to follow accommodative economic policy in response to the changes in part a). What fiscal policies would you suggest be used? What monetary policies could also be used? Use a diagram to show the effects of your suggested polices.

 

3. You are the President's economic advisor and you are trying to figure out where the U.S. economy is headed next year. You have the following forecasts for next year's AD, short-run AS, and long-run AS curves (output is given in trillions of 1998 dollars):

 

Price Level

 
Real GDP Demanded

Real GDP Supplied in the short run

Long-run Aggregate Supply

170

This year, real GDP is $8.9 trillion and the price level is 170. The President wants answers to the following questions:

a) What is your forecast of next year's real GDP?

b) What is your forecast of next year's price level?

c) What is your forecast of the inflation rate?

d) What will happen to the unemployment rate?

e) Will real GDP be above or below trend? By how much?

 

4. Use the information in problem 3 to answer the following questions (use diagrams in your answers):

a) What will have to be done to aggregate demand to move the economy to potential output? What type of monetary policy could be used to achieve this objective? What fiscal policy could be used to achieve this objective?

b) What will the price level be if aggregate demand is manipulated to move the economy to potential output? (For simplicity you can assume that the AD and AS are straight lines).

 

5. Use the information available on the Internet (http://www.stls.frb.org/fred/data/wkly.html) to obtain the data necessary to answer the following questions.

a) What were the interest rates on 3-month U.S. Treasury bills (the data series is called: 3-Month Constant Maturity Rate) on:

    1. January 2, 1998
    2. April 3, 1998
    3. July 3, 1998
    4. October 2, 1998

b) What were the interest rates on 10-year U.S. Treasury bonds (the data series is called: 10-Year Constant Maturity Rate) on:

    1. January 2, 1998
    2. April 3, 1998
    3. July 3, 1998
    4. October 2, 1998

c) Draw the yield curves for:

    1. January 2, 1998
    2. April 3, 1998
    3. July 3, 1998
    4. October 2, 1998

d) What were the changes in the yield curve form Jan. 2, 1998 to October 2, 1998 predicting about the future of the U.S. economy for 1998? Explain. On the basis of that information, what actions would you have recommended the Fed take at that time? Why?

e) Find the corresponding interest rates for September 10, 1999. What are the changes in the yield curve form October 2, 1998 to September 10, 1999 predicting about the future of the U.S. economy for 2000? Explain.

f) What is the probability of a recession according to the yield curve of September 10, 1999? (Note: Use the diagram from the WSJ article (Aug. 12, 1996) that we discussed in class to answer this question).

 

6. The country of Melrose has 100 million people over the age of 16. You are told that there is only one wage in the economy and that it is equal to $20 per hour. At this wage 80 million people are willing to work. You are told that when the wage equals $20 per hour there is no involuntary unemployment in Melrose.

a) Use the geometry of supply and demand to describe the labor market of Melrose (Make sure that you show the number of workers employed, voluntarily unemployed, and the total population).

b) Suppose that as a result of a decline in consumption and investment expenditures, 15 million workers become involuntarily unemployed. Illustrate these changes with the use of a new diagram (Make sure that you show the number of workers that are employed, involuntarily unemployed, voluntarily unemployed, and the total population).

c) What assumption is necessary to generate involuntary unemployment in the labor market?
