Answer: a. $200 billion
Explanation:
The Multiplier Effect (MPE) is used to calculate the Multiplier which then shows how much the GDP of the country will increase if a certain amount of money is induced into it.
The formula is;
Multiplier = 1 / ( 1 - MPE)
= 1 / ( 1 - 0.6)
= 2.5
The economy is now operating at $3,000 billion but they would want it to operate at $3,500 billion.
The difference of $500 billion is the amount that policy makers would like to add to the economy.
The Multiplier of 2.5 means that for every $1 spent, $2.5 will be added to the economy.
To get a $500 billion increase therefore, they would need to spend;
= 500 / 2.5
= $200 billion.
If they spend $200 billion, $500 billion will be added to the economy by the Multiplier Effect.
