b. Calculate the resulting change in the equilibrium quantity of real GDP demanded.

Respuesta :

Answer:

a) -4

b) -12 billion

Explanation:

Question 1) Calculate the Tax Multiplier

FIrst, we know that the Marginal Propensity to Consume = 0.8

Based on this, the formula is as follows:

Multipier = -Marginal Propensity to Consume/ (1-Marginal Propensity to Consume)

Multiplier = -0.8/ (1-0.8) = -0.8/ 0.2 = -4

The Tax  Multiplier = -4

Question 2) The resulting change in the equilibrium quantity of real GDP demanded

Change in Demand = Change in Tax x The Tax Multiplier

Change in Demand = $3 billion x -4

= -12

This means that the equilibrium quantity of the real GDP is -12 billion
