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 button
In 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
Answer:
Q 1. Real GDP increases by $1,000 billion
reason: When government cuts taxes, there is more disposable
income in the hands of the consumers, and they spend more,
increasing aggregate demand, and thereby real GDP. This increase
depends on the multiplier:1/(1-MPC) = 1/(1-0.8) = 5. So the change
in the real GDP = 200*5 = 1,000 billion dollars.
Q 2. increase; $500
reason: When government increases spending, it creates more demand, and the Aggregate demand increases. The extent of the increase depends on the multiplier: 1/(1-0.9) = 10. So, increase in real GDP = 50* 10 = 500 billion dollars.

Question 14 6 pts Assume the government cuts taxes by $250 billion. If the MPC is 0.8, what is the maximum potential impact on real GDP according to the simple Keynesian model? Real GDP decreases by $1,000 billion Real GDP decreases by $1.250 billion Real GDP increases by $1,000 billion Real GDP increases by $1.250 billion D Question 15 6 pts in Keynesian theory, if the marginal propensity to consume is 0.90 and government spending is increased by $40 billion,...
An economy has no imports and no taxes, the MPC is 0.8, and real GDP is $250 billion. Businesses decrease investment by $5 billion. Calculate the new level of real GDP. Explain why real GDP decreases by more than $5 billion. The new level of real GDP is $ billion. Real GDP decreases by more than $5 billion because the decrease in investment_ 0 A. induces an increase in saving O B. decreases the marginal propensity to consume O C....
please show solutions also. Thanks Question 4 In a simple Keynesian model, assume that the marginal propensity to consume (MPC) is 0.5. a) Find the government purchases multiplier b) Find the tax multiplier c) If the government wants to increase equilibrium real GDP by $ 500 billion, how much should the government increase spending? d) For the same purpose, how much should the government decrease taxes? According to Ricardian equivalence, do you think the government estimate is correct (should the...
Assume that equilibrium real GDP is $800 billion. Potential real GDP is 950 billion, the MPC IS .80, and the MPI is .40 If government spending and taxes both change by the same amount, how much must they change to eliminate the recessionary gap?
In the Keynesian-cross model, if the MPC equals 0.75 then a $2 billion increase in government spending increases the equilibrium level of income by __________. A) $1 billion. B) $3 billion. C) $4 billion. D) $2 billion.
15. According to the Keynesian-cross analysis, if MPC stands for marginal propensity to consume, then a rise in taxes of ΔT will: A) decrease equilibrium income by ΔT. B) decrease equilibrium income by ΔT/(1 – MPC). C) decrease equilibrium income by (ΔT)(MPC)/(1 – MPC). D) not affect equilibrium income at all. 16. Assume that a country’s MPS is equal to 0.4 and government expenditure is lowered by $20 billion, what is the effect on the country’s Y? A) It will...
Assume that equilibrium real GDP is $ 800 billion, potential real GDP is $ 950 billion, the MPC is .80, and the MPI is .40. a. How much taxes fall to eliminate the GDP gap? b.If government spending and taxes both change by the same amount, how much must they change to eliminate the recessionary gap?
please answer 7,8,9,10. thank you so much!!:)) SECTION In the simple Keynesian model with an MPC equal Keynesian model with an MPC equal to 0.80, a S50 billion increase in investment spending leads to a maximum: $50 billion increase in equilibrium income. b. 580 billion increase in equilibrium income $250 billion increase in equilibrium income. d. $400 billion increase in equilibrium income S500 billion increase in equilibrium income. when $2.000 increase in income causes a $1,800 increase in consumption spending...
Assume that Equilibrium GDP is $4,000 billion. Potential GDP is $5,000 billion. The marginal propensity to consume is 4/5 (0.8). By how much and in what direction should government purchases be changed? Group of answer choices increase by $200 billion increase by $1,000 billion decrease by $1,000 billion increase by $100 billion
What is the eventual effect on real GDP if the government increases its purchases of goods and services by $60,000? Assume the marginal propensity to consume ( MPC) is 0.75. What is the eventual effect on real GDP if the government, instead of changing its spending, increases transfers by $60,000? Assume the MPC has not changed. An increase in government transfers or taxes, as opposed to an increase in government purchases of goods and services, will result in O a...
