Question

The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 What is the equilibrium level of GDP? State to ONE decimal place

Answer 1

Answer: the answer is 90.0

Explanation:

From the question above, we are given:

G = 11

I = 4

X = M = 0

Consumption function is:

C = k + cY

Where:

k = 3

c = 0.8

The GDP of a nation is given as:

Y = C + I + G + NX

By imputing the values into the GDP equation, we have:

Y = k + cY + 4 + 11 + 0

Y = 3 + 0.8Y +15

Y - 0.8Y = 18

0.2Y = 18

Y = 90.0
