Assume a simple model without any government or net exports. If a decrease in autonomous investment by 40 leads to a final decrease in GDP by 160, then the marginal propensity to save is _________. Show your calculations.
Answer
Multiplier =change in GDP/change in investment
=-160/(-40)
=4
Multiplier =1/MPS
MPS=1/multiplier =1/4=0.25
the MPS(marginal propensity to consume) is 0.25

The net export function illustrates that:A) net exports are a positive function of domestic income.B) net exports are independent of domestic income.C) net exports are a negative function of domestic income.D) imports are independent of domestic income.E) exports are independent of foreign income. Suppose the marginal propensity to import for country A is 0.4. Calculate the change in total value of imports of the country if national income increases by $100,000.A) $16,000B) $20,000C) $60,000D) $40,000E) $25,000 An MPI of 0.4 indicates that...
Consider the following economy: Autonomous Spending: $1,000 Investment: $2,000 Government Spending: $3,000 Exports: $500 C1: .55 Tax Rate: .22 Marginal Propensity to Import: .09 a. What is Output (Y) in this economy? __________________ b. What is the multiplier? _________________________ c. What is the autonomous component of this economy (y-intercept): _______________ d. If Investment drops by 20%, by how much must Government spending change to offset the drop in Y: $__________ ($ change in spending) __________% (% change in spending) e....
Suppose the government raises its revenue by a net tax of 35 percent on income, t = 0.35. The marginal propensity to consume out of disposable income is 0.85 and the marginal propensity to import is 0.25. Note: Keep as much precision as possible during your calculations. Your final answer should be accurate to at least two decimal places. a) What is the slope of the AE function? What is the size of the multiplier? Slope of AE = 0...
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
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...
Consider an economy in which taxes, planned investment, government spending on goods and services, and net exports are autonomous, but consumption and planned investment change as the interest rate changes. You are given the following information concerning autonomous consumption, the marginal propensity to consume, planned investment, government purchases of goods and services, and net exports: Ca = 1,500 – 10r; c = 0.6; Ta = 1,800; Ip = 2,400 – 50r; G = 2,000; NX = -200 (a)Derive Ep and...
An economy is initially at full employment, but a decrease in planned investment spending (a component of autonomous expenditure) pushes the economy into recession. Assume that the marginal propensity to consume (mpc) of this economy is 0.75 and that the multiplier is 4 a. How large is the recessionary gap after the fall in planned investment? The recessionary gap is times the size of the fall in planned investment. b. By how much would the government have to change its...
