In equilibrium level of output Aggregate Demand (AD) =Aggregate Supply(AS)
Y is Income
Consumption function (C)=100+0.95Y
I (Planned Investment)=200
Y= (Consumption +Investment) or (Consumption + Saving)
Y=100+0.95Y+200
Y=300+0.95Y
Y-0.95Y=300
0.05Y=300
Y=300/0.05 =300*100/5=6,000
Ye=$6,000
Verification:
AS=Y =6000
AD=C+I
C=100+0.95Y=100+0.95×6,000
C=100+5,700=5,800
I=200
AD=C+I=5,800+200=6,000
Hence proved AS=AD and equilibrium level of output is 6000

In the Keynesian cross, assume that the consumption function is given by C=200+0.75(Y-T) Planned investment is 100; government purchases and taxes are both 100. a) Graph planned expenditure as a function of income. b) What is the equilibrium level of income? c) If government purchases increase to 125, what is the new equilibrium income? d) What level of government purchases is needed to achieve an income of 1,600?
Suppose consumption is given by: C=100+0.5(Y-T), planned investment is 200, government spending is 100, and the government is running a balanced budget. The tax multiplier is:

Consumption spending in a country is represented by C = 1800+ 0.8(Y-T ). Planned investment is 900, government purchases G = 0, net exports NX = 100 and T = 0.2Y. Write down planned aggregate spending of the economy as a function of Y. Zero points if you do not show your work. (3) An important trading partner of the country goes through a major recession, decreasing the country’s net exports by $500. Use the Keynesian AE model to analyze...
