18. Assume the MPC is 0.80 and government spending declines by $500 billion. What is the effect of this decline on RGDP?
19. Assume the MPC is 0.90 and consumer income taxes increase by $250 billion. Calculate the effect of this increase on RGDP.
20. Assume the MPC is 0.75 and consumer spending increases by $200 billion, investment spending increases by $150 billion, and government spending declines by $75 billion. What is the impact on RGDP?
Ans18) RGDP declines by 2,500
change in RGDP = - 500/( 1-0.80) = - 2,500
Ans19) RGDP declines by 2250
Change in RGDP = - 0.90/(1-0.90) * 250 = -2250
Ans20) RGDP increases by 1100
Aggregate spending = 200+ 150 - 75 = 275
Change in RGDP = 275/( 1 - 0.75) = 1100

Assume the government cuts taxes by $200 billion. If the MPC is 0.8, what is the maximum potential impact on real GDP according to the simple Keynesian model? Real GDP increases by $1,000 billion Real GDP Increases by $800 billion Real GDP decreases by 51.000 billion Real GDP decreases by 5000 buttonIn Keynesian theory, if the marginal propensity to consume is 0.90 and government spending is increased by $50 billion, then real income (GDP) will maximum of billion by a decrease: $500 decrease $50 Increase: $500 Increase: $50

Say the MPC is .6 and suppose taxes are cut by $300 billion and government spending is increased by $200 billion. Use the multipliers to figure the effect of that change in fiscal policy on spending. The increase due to the tax cut =______. The increase due to the increase in government spending =_______. The total increase=_________. (Government spending multiplier = 1/(1-mpc) Tax multiplier = mpc/(1-mpc))
Investment Problem: 1. Assume the MPC is 3/4, if investment spending increase by $50 billion, the level of GDP will: 2. Assume the MPC is 2/3, if investment spending decreases by $30 billion, the level of GDP will: Export Problem: 3. If the multiplier in an economy is 4, a $50 billion increase in exports will: 4. If the multiplier in an economy is 3,a $30 billion decrease in exports will: Balanced Budget Problem: 5. If the MPC is .75...

1. Suppose the MPC is 0.8 and the crowding out effect is $30 billion. The government aims to increase GDP by $250 billion. a) Calculate the fiscal multiplier b) how much the government needs to increase spending to increase GDP by $250 billion c) Calculate the tax cut multiplier, d) How much the government needs to cut taxes to increase GDP by $250 billion? e) Explain why the tax multiplier is smaller than the fiscal multiplier. f) If you were...
1.) If the marginal propensity to consume is 0.75 and investment spending increases by $200 billion, equilibrium GDP will increase by____. $350 billion $150 billion $200 billion $266.7 billion $800 billion 2.) AE = 3000 + 0.75*RGDP. Given this equation for AE, find equilibrium GDP $1,000 $750 $12,000 $2,250 3.) The four components of aggregate planned expenditure are the real interest rate, disposable income, wealth, and expected future income the real interest rate, consumption expenditure, investment, and government expenditures consumption...
