The estimation of the marginal propensity to consume should be 2 ÷3
The computation of the estimation of the marginal propensity to consume is shown below:
But before that the multiplier should be
= Total demand for goods & services ÷ government spending
= $42 billion ÷ $14 billion
= 3
Now as we know that
Multiplier = 1 ÷ (1 - MPC)
3 = 1 ÷ (1 - MPC)
1 - MPC = 1 ÷ 3
MPC = 1 - 1 ÷3
= 2 ÷ 3
Therefore we can conclude that The estimation of the marginal propensity to consume should be 2 ÷3
