A media report states: "Firms cut back on investment spending causing a recession." Prior to the recession assume the economy of Keynesland was producing at its potential real GDP and the price level was stable. The decrease in I_G created a negative GDP gap, actual real GDP is $100 billion below potential real GDP. Policymakers decide to use discretionary fiscal policyto increase aggregate demand.

POLICY OPTION 1: A change in government purchases.

Predict how much government purchases (G) would have to change in order to return the economy to its full-employment level of real GDP. Assume the economy's marginal propensity to consume or

MPC = 0.90 and that there is no crowding-out effect.

MUST SHOW THE FORMULA AND YOUR CACULATIONS FOR 1a - d

a. To close the recessionary gap government purchases must _____ by $_____ billion.

Formulas: Multiplier =

GDP = Multiplier x G

POLICY OPTION 2: A change in taxes.

Predict how much tax revenues would have to change in order to return the economy to its full-employment level of real GDP. The MPC = 0.90 and there is no crowding-out effect.

b. To close the recessionary gap consumption (C) must ______ by $______ billion.

Formula: GDP = Multiplier x C

To achieve this change in the level of consumption spending

c. tax revenues must ___________ by $______ billion

d. which will ______ disposable income by $_____ billion
