Answer: 0.8; 5
Explanation:
From the question, we are informed that people decide to save 20 percent of their incomes. We should note that the addition of the marginal prospensity to consume(MPC) and the marginal prospensity to save(MPS) will be equal to 1.
Therefore, the value of the marginal propensity to consume will be:
= 1 - 20%
= 1 - 0.2
= 0.8
The value of the spending multiplier will be calculated as:
= 1/MPS
= 1/0.2
= 5
