1) Use figure below to answer to the subsequent question
From figure, indicate by using the numbers where the economy is located if the interest rate is below the equilibrium level and people are holding less money than they desire.
2) Suppose which the economy starts at equilibrium and the mpc = 0.75. Illustrate what would be the effect of a $300 increase in government spending once all the rounds of the multiplier process are complete?
3) Suppose which the economy starts at equilibrium and the mpc = 0.8. Illustrate what would be the effect of a 300 increase in taxes once all the rounds of the multiplier process are complete?
