- 1) Determine the value of the multiplier for this economy, and find the equilibrium value of Y.Suppose that an initial $10 billion increase in investment spending expands GDP by $10 billion in the first round of the multiplier process. Also suppose that GDP and consumption both rise by $6 billion in the second round of the process. what is the MPC? What is the size of the Multiplier? If, instead, GDP and consumption both rose by $8 billion in the second round, what would have been the size of the multiplier?An economy has a marginal propensity to consume of 0.5, and Y*, the income-expenditure equilibrium GDP, equals $500 billion. Given an autonomous increase in planned investment of $10 billion, answer the following questions. a. What is the value of the multiplier? Value of the multiplier = b. What would you expect the total change in Y* to be based on the multiplier formula? Change in Y* based on the multiplier = billion c. What is the total change in real GDP after the 10 rounds? It may be beneficial to make a table on a separate sheet of paper to calculate the change in real GDP for each of the rounds, and then add up the values. Total change in real GDP (10 rounds) =
- Suppose that an initial $ 10 billion increase in investment spending expands GDP by $ 10 billion in the first round of the multiplier process. Also suppose that GDP and consumption both rise by $ 6 billion in the second round of the process. Instructions: In parts a and b, round your answers to 1 decimal place. In part c enter your answer as a whole number. A) What is the MPC in this economy? B) What is the size of the multiplier? C) If, instead, GDP and consumption both rose by $ 8 billion in the second round, what would have been the size of the multiplier?Consider a hypothetical economy where there are no taxes and no foreign trade, and households spend $0.90 of each additional dollar they earn and ; the marginal propensity to save (MPS) for this save the remaining $0.10. The marginal propensity to consume (MPC) for this economy is economy is ; and the multiplier for this economy is Suppose investment spending in this economy decreases by $150 billion. The decrease in investment will lead to a decrease in income, generating a decrease in consumption that decreases income yet again, and so on. Fill in the following table to show the impact of the change in investment spending on the first two rounds of consumption spending and, eventually, on total output and income. Hint: Be sure to enter a negative sign in front of the number if there is a decrease in consumption. Change in Investment Spending = -$150 billion First Change in Consumption = $ Second Change in Consumption $ Total Change in Output = $ billion billion billion In reality,…In an economy with no government and no foreign sectors, autonomous consumer spending is $250 billion, planned investment spending is $350 billion, and the marginal propensity to consume is 2/3. c) What is Y*, income-expenditure equilibrium GDP? d) What is the value of the multiplier? e) If planned investment spending rises to $450 billion, what will be the new Y*?
- Answer all four questions based on the following diagram. 1. Calculate the MPC in the above diagram. 2. Based on Diagram 1, If private Investment of $100 is added to the existing C, calculate the new equilibrium level of NI. 3. Given your answer to the previous question (question #2) calculate by how much G should change, if the full employment level in the economy is at $3000. 4. Based on the answer to the previous question (question #3), if half of those government expenditures are financed through lump sum taxes, calculate the new level if NI? (C+I+G)1. Assume in a simple economy that the level of saving is –500 when aggregate output equals zero and that the marginal propensity to save is 0.2. Derive the saving function and the consumption function, and draw a graph showing these functions. At what level of aggregate output does the consumption curve cross the 45° line? Explain your answer and show this on the graph.2. Use your answer to the previous problem to calculate the MPC, MPS, government spending multiplier, and tax multiplier. Draw a graph showing the data for consumption spending, planned aggregate expenditures, and aggregate output. Be sure to identify the equilibrium point on your graph. Sorry, these two questions are linked. I totally forgot.Consider the following is the economy of Country Z: C = 200 + 0.85Y I = 100 Answer the following questions: Calculate the equilibrium level of output algebraically using the saving-investment (S-I) approach. (b) What is the value of saving at the equilibrium output from part (a)? (c) Suppose the investment increases to 200. What is the new equilibrium level of output? Calculate the value using the multiplier approach.
