- Suppose that investment demand increases by $100. Assume that households have a marginal propensity to consume of 80 percent. Compute the first three rounds of multiplier effects as follows: a) What are the first cycle changes in spending? Total cumulative change equals? b) What are the second cycle changes in spending? Total cumulative change equals? c) What are the third cycle changes in spending? Total cumulative change equals?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) =1) Determine the value of the multiplier for this economy, and find the equilibrium value of Y.

How does the size of the multiplier relate to the size of the MPC? The MPS? What is the logic of the multiplier-MPC relationship?47)Which one is TRUE? Select one: a. The larger the MPC, the smaller the multiplier. b. The multiplier is the ratio of the change in autonomous expenditure to the change in real GDP c. The real world multiplier is larger than the textbook multiplier when we take into account the impact of changes in GDP on imports, inflation and the interest rate. d. The real world multiplier is smaller than the textbook multiplier when we take into account the impact of changes in GDP on imports, inflation and the interest rate.Question 1: You are given the data concerning Freedonia, a legendary country i. C = 200 + 0.8Y ii. I = 100 a) What is the MPC to consume and what is the MPS? b) Solve for equilibrium income. c) Suppose I changes to 110, what is the new equilibrium level of income?

How are inventory changes related to AE and Y? 5. Define the multiplier and the marginal propensities to consume (MPC) and save (MPS). What is the relationship between the MPC and the multiplier? 6. Compare and contrast the short run Keynesian and long run Neoclassical views of the aggregate supply and Phillips curves 7. For each the following economies, calculate equilibrium Y*, the multiplier, and the size of the recessionary or inflationary gap, if any. a. AE= 250 +.75 Y Yf= 1200 b. AE= 400+ .9 Y Yf= 3000 c. AE= 300 +. 8Y Yf=1500 d. AE= 300+ .67 Y Yf=1000Table 2 shows elements in the national income accounts of an economy. Assume the economy is currently in equilibrium. elements billions Consumption (total) 80 Investment 9 Government Expenditure. 6 Imports 15 Exports 8 C) If national income now rises by £22 billion and as a result, the consumption of domestically produced goods rises to £80 billion. Calculate the marginal propensity to consume (MPC). D) What is the value of the multiplier? E) Comment on the results in part (c) and (d).Explain the multiplier intuitively. Why is it that an increase inplanned investment of $100 raises equilibrium output by morethan $100? Why is the effect on equilibrium output finite? Howdo we know that the multiplier is 1/MPS?
- Income and Expenditure — End of Chapter Problem 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) = billion d. How do your answers to the change in GDP and Y compare? The answer to total change in GDP after 10 rounds and the change in Y* based on the multiplier formula areAssume the marginal propensity to consume is 0.8. If consumer spending rises by $20 billion, then total income through the multiplier effect will: Increase by $100 billion Decrease by $100 billion Increase by $10 billion Will not change How do I calculate this?14. Given this diagram; what is the level of I (investment spending)? 15. Given this diagram; what is the level of Xn (net exports)? 16. Given this diagram; what is the mpc (marginal propensity to consume?
