Get started for freeAssume that the consumption schedule for a private open economy is such that consumption C = 50 + 0.8Y. Assume further that planned investment Ig and net exports Xn are independent of the level of real GDP and constant at Ig = 30 and Xn = 10. Recall also that, in equilibrium, the real output produced (Y) is equal to aggregate expenditures: Y = C + Ig + Xn.
Calculate the equilibrium level of income or real GDP for this economy.
What happens to equilibrium Y if Ig changes to 10? What does this outcome reveal about the size of the multiplier?
If the multiplier is 5 and investment increases by \(3 billion, equilibrium real GDP will increase by
\)2 billion.
\(3 billion.
\)8 billion.
$15 billion.
Depict graphically the aggregate expenditures model for a private closed economy. Now show a decrease in the aggregate expenditures schedule and explain why the decline in real GDP in your diagram is greater than the decline in the aggregate expenditures schedule. What term is used for the ratio of a decline in real GDP to the initial drop in aggregate expenditures?
Assuming the level of investment is \(16 billion and independent of the level of total output, complete the following table and determine the equilibrium levels of output and employment in this private closed economy. What are the values of the MPC and MPS?
Possible Levels of Employment, Millions | Real Domestic Output (GDP = DI), Billions | Consumption, Billions | Saving, Billions |
40 | \)240 | $244 | |
45 | 260 | 260 | |
50 | 280 | 276 | |
55 | 300 | 292 | |
60 | 320 | 308 | |
65 | 340 | 324 | |
70 | 360 | 340 | |
75 | 380 | 356 | |
80 | 400 | 372 |
True or False. The aggregate expenditures model assumes flexible prices.
