Assume that the equations below describe the expenditures within a particular macroeconomy and that these equations conform to the assumptions we've made in the lecture regarding the fixed price level Aggregate Expenditure model. All values for expenditure and income are dollar amounts, but for simplicity, we've dropped the $ below.
| C = 0.8(DI) + 1000 | C = Consumption expenditure, DI = Disposable Income |
| I = 2000 | I = Investment expenditure |
| G = 1000 | G = government expenditure |
| X = 1600 | X = spending on exports |
| M = 1800 | M = spending on imports |
| DI = Y - T | Y = real GDP, T = tax revenues/> |
| T = 1000 | |
| Yp = 12000 | Yp = Potential GDP |
Given the equations above, we can describe the GDP, government budget, and net exports in this economy. Select three characteristics from the list below which accurately describe this economy. Note that there is no partial credit on this question. I.e., your answer will either be all correct, or all wrong.
| a. |
inflationary gap |
|
| b. |
recessionary gap |
|
| c. |
no output gap |
|
| d. |
government budget surplus |
|
| e. |
government budget deficit |
|
| f. |
balanced government budget |
|
| g. |
trade deficit |
|
| h. |

|
| i. |
net exports of zero |
TRUE / FALSE
1. True False In the aggregate expenditures model presented in the textbook,
investment is assumed to rise with increases in real GDP and fall with decreases in real GDP.
2. True False When C + Ig = GDP in a private closed economy, S = Ig and there are no unplanned changes in inventories.
3. True False The risk-free interest rate is the rate on long-term U.S. government bonds.
4. True False Bond prices and interest rates are directly or positively related.
5. True False The public debt is the accumulation of all deficits and surpluses that have occurred through time.
6. True False The M2 money supply may be larger or smaller than the M1 money supply depending on the size of small-denominated time deposit balances and Money Market Mutual Fund balances held by individuals.
7. True False Excess reserves are the amount by which required reserves exceed actual reserves.

9. True False The equilibrium price level and equilibrium level of real GDP occur at the intersection of the aggregate demand curve and the aggregate supply curve.
