Calculate the net cumulative change in the aggregate expenditure
Learning Goal: I’m working on a economics question and need an explanation and answer to help me learn.10.1 If the Marginal Propensity to Consume (MPC) is .90, estimate the total (multiplied) effect of government purchases/spending of $100B in the economy in terms of its aggregate expenditure (Hint: Multiplier = 1 / 1 – MPC). Calculate the net cumulative change in the aggregate expenditure if taxes were cut by $200 billion and MPC is estimated to be .75. What if government expenditure was increased by $200 billion? (Hint: Total change in expenditure = multiplier x new expenditure or spending injection)10.2 Explain why a high level of government debt is bad for the economy?10.3 Why automatic stabilizers help to smooth out the effects of cyclic boom and bust cycles on the economy?
