Can anyone help me to solve the following question??
I don't understand how to do part (c) and (d).
its really urgent...please help!
Many thanks: )
18. Consider a simple goods market model:
Consumption: C = a + bY
Investment: I = ñ âËâ òi
Government expenditure: G = G0
(a) Use a diagram of simple Keynesian model (Keynesian cross) to illustrate
the equilibrium national output. You should clearly indicate the numerical
values for the intercept and the equilibrium output in the diagram.
(b) Assuming interest rate remains constant, calculate the government
multiplier.
(c) Call the equilibrium output as Y1 after the government expenditure
increases by $1 under the assumption in (b).
If interest rate is flexible, after the $1 increase in government expenditure,
output in the goods-money market equilibrium is Y2.
Use a diagram (donââ¬â¢t calculate the values) to indicate Y1 and Y2.
(d) For (b) and (c), we assume general price level is fixed. If price is flexible,
the equilibrium output is Y3. Illustrate Y1, Y2, and Y3 in the aggregate
supply-aggregate demand model and in the IS/LM model.
