HW on the Long-Run Macro Model
Diane K. Monaco
[Macro Model LR] Consider the following GDP equation data (Macro Model) for an economy:
Y= C + I + G + (EX - IM)
C= 1500 + (mpc) Y
I = 1250
G = 800
(EX - IM) = -250
1. Calculate the multiplier (M) and equilibrium GDP using the above LR Macro Model and an mpc = .80
2. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 500, G = 1000, I =2770, (EX - IM) = -250, and MPC = 0.72
3. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 550, G = 1600, I =1700, (EX - IM) = 300, and MPC = 0.69
4. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 700, G = 1400, I =1250, (EX - IM) = -250, and MPC = 0.78
5. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 680, G = 2600, I =1970, (EX - IM) = 300, and MPC = 0.82
6. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 1200, G = 1850, I =1390, (EX - IM) = 270, and MPC = 0.72
7. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 1360, G = 1300, I =2200, (EX - IM) = -150, and MPC = 0.69
8. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 1100, G = 2350, I =1250, (EX - IM) = -250, and MPC = 0.78
9. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 2000, G = 3400, I =1800, (EX - IM) = 280, and MPC = 0.82
10. Calculate the multiplier (M) and equilibrium GDP for the following:
Autonomous Consumption (dissaving) = 2240, G = 1900, I =1150, (EX - IM) = 350, and MPC = 0.84
