If the Keynesian AD shortfall is $425 billion and MPC is 0.86, calculate the size of the desired tax cut needed: a. $48.7 billion b. $69.2 billion c. $83.3 billion d. $92.6 billion e. $116.1 billion

How much government spending needs to be increased to maintain full employment in the economy If the economy was facing recessionary gap of $900 billions? Assume MPC is .9. How much tax cut should government give if they wanted to eliminate this recessionary gap through tax cut?

If MPC = 0.9, short run equilibrium real GDP is $1,000, and full-employment real GDP is $2,000, then how much should government spending change to bring about full employment? A.decrease by $100 B.increase by $1,000 C.increase by $900 D.increase by $100

2. For simplicity, we normally treat aggregate tax payments (T) as determined by politics or other factors unrelated to output. However, suppose that aggregate tax payments are proportional to income. That is, T=t·Y, where tis the marginal tax rate and is between o and 1. a. How, if at all, would this change in our assumptions affect the Keynesian cross diagram? b. Would this change increase, decrease, or have no impact on the multiplier effect, or is it not possible to tell? (That is, how would the effect of a given vertical shift of the planned expenditure line compare with what it was before?)
