If the marginal propensity to consume is 0.75, and there is no investment accelerator or crowding out, a $115 billion increase in government expenditures would shift the aggregate demand curve right by $460 billion, but the effect would be smaller if there were an investment accelerator. $345 billion, but the effect would be smaller if there were an investment accelerator. $345 billion, but the effect would be larger if there were an investment accelerator. $460 billion, but the effect would be larger if there were an investment accelerator.

Respuesta :

Answer: $460 billion, but the effect would be larger if there were an investment accelerator.

Explanation:

If the MPC = 0.75 and there is no investment accelerator or crowding out, then a $115 billion increase in the government expenditures would result in the shift in the aggregate demand curve right by:

= $115 billion ÷ (1 - 0.75)

= $115 billion ÷ 0.25

= $115 billion × 1/0.25

= $115 billion / 0.25

= $460 billion.

Therefore, there'll be a shift in the aggregate demand curve right by $460 billion, but the effect would be larger if there were an investment accelerator
