The Multiplier in the Simple Model with No Income Taxes
The simple government purchase multiplier is given by 1/(1 - MPC). Suppose that the U.S. MPC is 0.9. Calculate the government purchase multiplier. If the U.S. government increases its spending by $100 billion to stimulate the economy devastated by the Coronavirus crisis, how much will U.S. GDP increase in the simple model?
Answer
Multiplier =1/(1-MPC)
=1/(1-0.9)
=10
the government purchase multiplier is 10
Change in GDP =change in government spending * multiplier
=100*10
=$1000 billion
the GDP increases by $1000 billion

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
What is the formula for the government spending multiplier? Tax Multiplier? Calculate both multipliers assuming an MPC of .6 Graph an economy in the AD AS model with Potential Output of $600 and Real GDP at $450. Calculate the output gap and identify it as a recessionary or inflationary gap. How much fiscal stimulus is needed to close the gap? show work and use formulas for government spending multiplier and tax multiplier. Show all work Assume the government increases government...
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...
The spending multiplier, m, is 1/(1 MPC). a) If the MPC is 0.9, what is the spending multiplier? b) Now suppose government spending increases by $90 million. By how much will GDP rise? $million
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,...
QUESTION 12 In the aggregate expenditure model if the government of Pasedonia decides to increase government spending by $ 100 billion and to finance this increase in government spending the government of Pasedonia increases taxes by $ 100 billion what effect will this have on the economy? (assume MPC=0.75) O A GDP stays the same OB GDP increases by $ 100 billion OC. GDP will increase by $ 400 billion D.GDP will decrease QUESTION 13 An example of an automatic...
In the simple Keynesian model, taxes do not depend on income (T
= Ta). Suppose Ta = 80 and:
C = 250 + 0.75 YD
Ip = 64
G = 100
NX = 20
A. Calculate the equilibrium GDP and show graphically. What is
the budget surplus (or deficit)? Hint: BS = T - G
B. Suppose in order to reduce the deficit, government spending
is reduced by 20 (from 100 to 80. Calculate the new equilibrium GDP
and show...
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))
