Macroeconomic Equilibrium: IS-LM and WS-PS Analysis
IS-LM Model in a Closed Economy
QUESTION 1:
Consider a closed economy defined by the following equations:
- Consumption (C): 200 + 0.4(Y – T)
- Investment (I): 150 + 0.1Y – 1000(r + x)
- Government Spending (G): 250
- Taxes (T): 100 + 0.2Y
- Real Interest Rate (r): 0.05 (Set by the Central Bank)
- Risk Premium (x): 0.02
Equilibrium Output and the IS Relation
To find the IS relation, we start from the goods market equilibrium condition (Y = Z):
Y = [200 + 0.4(Y – (100 + 0.2Y))] + [150 + 0.1Y – 1000(r + x)] + 250
