Answer:
- A) reduce government purchases by $4 billion
Step-by-step explanation:
Vulcan economy :
MPC = 0,6
Reduce Output by $10 billion.
To find the number that will have a negative impact in the economy of 10 billion, we need a number that multiply by the multiplier gives 10 billion.
The multiplier will be
1 / (1- MPC) =
1 / (1- 0,6) =
1 / 0,4 =
2,5
Then the Vulcan economy need to reduce goverment purchases by $4 billion.
The solution is as follows: 2,5 (multiplier) * $4 billion = $10 billion of decrease in the GDP
