Answer:
i) 2
ii) 1.9
iii) $200 billion decrease in investment will lead to a $380 billion decrease in output
Step-by-step explanation:
i) Determine the oversimplified multiplier for this economy
MPC value of the economy = 0.5
spending multiplier = 1 - / 1 - MPC VALUE )
∴ oversimplified multiplier = 1 / 0.5 = 2
ii) Given that the Government implement an income tax of 5%
The Multiplier of the economy = 1 / [ 1 - MPC (1-t) ]
= 1 / [ 1 - 0.5(1-0.05 )]
= 1 / ( 1 - 0.475 ) = 1.9
iii) $200 billion decrease in investment will lead to a $380 billion decrease in output
total change in output = 1.9 * 200 =$ 380
