PROBLEM ON

THE AGGREGATE EXPENDITURE MODEL

 





I. An econometric study of the Kazkhstan economy produced the following set of equations:

A. Consumpton C = 30 + .8 * YD

B. Imports Z = .2 * Y

C. Transfer Payments TR = 30 - .05 * Y

D. Taxes TX = 40 + .2 * Y

(YD = Disposable Income and Y = GDP)

II. An economic team from the World Bank has projected the following levels of autonomous spending for 1998.

A. I = 40

B. G = 90

C. X = 28

QUESTIONS:

PART A: (Computing the multipliers)

Calculate the following values for the Kazkhstan economy:

1. The net tax rate ________________

2. The MPC out of YD ________________

3. The MPC out of GDP ________________

4. The slope of the Aggregate Planned
Expenditure (APE) curve ________________

5. The Autonomous spending multiplier ________________

6. The Autonomous transfer payment
multiplier ________________

7. The Autonomous tax multiplier ________________

8. The Balanced budget multiplier ________________

PART B: (Projecting GDP and its components)

Make the following projections for the Kazkhstan economy in 1998:

1. Total autonomous spending ________________

2. Equilibrium GDP ________________

3. Imports ________________

4. International Trade Deficit ________________

5. Transfer payments ________________

6. Taxes ________________

7. Net Taxes ________________

8. The Government Deficit ________________

9. Disposable Income ________________

10. Consumption ________________

11. Saving ________________


C. Analysis

1. How large would Net Taxes (Taxes minus Transfers) be if GDP were zero? _________________

2. How large would the equilibrium GDP have to be in 1998 to have a zero trade deficit? ____________________________________

3. How large would the equilibrium GDP have to be in 1998 in order to have a zero government deficit? ________________________

4. If the potential real GDP is less than the projected GDP for 1995, what is likely to happen to the price level?
___________________________________

5. If prices rise in 1998, what will happen to projected real GDP in 1998? ________________________________


D. Fiscal Policy

A government analysis of the Kazakhstan economy produced an estimate that the full employment GDP is 210.

1. How large a change in projected GDP would be required to
bring the equilibrium real GDP down to 210? __________________________

2. How large a change in government spending would be required to bring the equilibrium real GDP down to 210? __________________________

3. How large a change in autonomous taxes would be required to bring the equilibrium real GDP down to 210? ____________________________

4. How large a balanced change in the government budget would be required to bring the equilibrium real GDP down to 210?
