Suppose that Congress and the President are considering an increase in government expenditures of $50 billion. They consult with two economists: Alan and Robert. Alan believes that the marginal propensity to consume (MPC) is 0.9 and Robert believes that it is 0.5 If Alan is correct, then the increase in government spending will cause GDP to increase by ____, and if Robert is correct, then the government spending increase will cause GDP to increase by ____ (B)
A. $450 billion, $250 billion
B.$500 billion, $100 billion
C.$250 billion, $150 billion
D.$150 billion, $250 billion
E.$45 billion, $25 billion

Suppose economists observe that an increase in government spending of $5 billion raises the real aggregate output level by $20 billion. (a) In the absence of the crowding out effect, what would the numerical value of marginal 1. propensity to consume (MPC)? (b) Now suppose the crowding-out effect also comes to play.Should the new numerical value of marginal propensity to consume (MPC) be larger or smaller than that of your answer in part (a)? Explain. (Hint: the multiplier effect and...
Suppose the economy is in a recession and the president wants to stimulate production and create jobs. To do this, he has decided to increase government spending. Some of his economic advisors are suggesting the marginal propensity to consume (MPC) has a value of 0.9 and others are suggesting the value is 0.8. If the MPC has a value of 0.9, then the expenditure multiplier has a value of Click to select) If the MPC has a value of 0.8,...
3. Suppose the government increases education spending by $30 billion. How much additional consumption will this increase cause? Assume the MPC (marginal propensity to consume) to be 0.75.
Use the aggregate expenditures model and assume the marginal propensity to consume is 0.90. An increase in government spending of $1 billion would result in an increase in GDP of?
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,...
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...
Calculate the resulting change in GDP for each of the following MPCs when the government decreases taxes by $225 billion (change in taxes equals -$225 billion) Instructions: Round your answers to one decimal place. a. The marginal propensity to consume (MPC) = 0.2. The change in GDP is $ O b illion. b. The marginal propensity to consume (MPC) = 0.5. The change in GDP is $ billion. C. The marginal propensity to consume (MPC) = 0.8. The change in...
Suppose that investment expenditures increases by $300 billion in a closed and private economy (no government or foreign trade). Assume further that households have a marginal propensity to consume of 75 percent. What will be the final cumulative impact on spending? $900 billion $225 billion $375 billion $525 billion
7. If consumption increases by $400 Billion and incomes increase by $500 Billion in a year, what can we say about the marginal propensity to consume? 8. If the dollar were to strengthen against other world currencies, explain the effect this would have on net exports. 9. With an MPC of.9, what would the change in GDP be if Government Spending increased by $500 Million?
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
