The following equations describe an economy: Y = C + I + G + X – M [where X=exports, M=imports] C = 150 + 0.7*(Y - T) T = 30 I = 300 G = 60 X = 140 M = 100 + 0.2*(Y - T) Which of the following statement is true? The value of the government spending multiplier is 3.33. If exports increase by 10, equilibrium Y will increase by 20. If government spending increases by 40, equilibrium Y will increase by 333. Without any changes, the equilibrium level of Y is 2167.

C = 150 + 0.7*(Y - T)

T = 30

I = 300

G = 60

X = 140

M = 100 + 0.2*(Y - T)

Which of the following statement is true?

  1. The value of the government spending multiplier is 3.33.
  2. If exports increase by 10, equilibrium Y will increase by 20.
