Question #59325

Given that:

G=20

I=35

C=0.9Yd+70

T=0.2Y+25

Calculate the balance of national income.

G=20

I=35

C=0.9Yd+70

T=0.2Y+25

Calculate the balance of national income.

Expert's answer

If G = 20, I = 35, C = 0.9Yd + 70, T = 0.2Y + 25 and Yd = Y - T, then the balance of national income (or GDP) is:

Y = C + I + G = 0.9Yd + 70 + 35 + 20 = 0.9*(Y - 0.2Y - 25) + 125 = 0.72Y - 22.5 + 125 = 0.72Y + 102.5;

Y = 0.72Y + 102.5;

0.28Y = 102.5;

Y = 366.07.

Y = C + I + G = 0.9Yd + 70 + 35 + 20 = 0.9*(Y - 0.2Y - 25) + 125 = 0.72Y - 22.5 + 125 = 0.72Y + 102.5;

Y = 0.72Y + 102.5;

0.28Y = 102.5;

Y = 366.07.
