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. |
trade surplus |
|
| i. |
net exports of zero |
An economy with zero net exports is described below:
| C | = 100 + 0.6 (Y 'T) |
| I p | = 70 |
| G | = 120 |
| NX | = 0 |
| T | = 150 |
| The multiplier in this economy is 2.5. | |
A. Find short-run equilibrium output.
Instruction: Enter your response as an integer value.
Short-run equilibrium output: .
B. Economic recovery abroad increases the demand for the country's exports; as a result, NX rises to 80.
Instruction: Enter your response as an integer value.
Short-run equilibrium output (Click to select)decreases/ increases to ________ .
C. Assume that foreign economies are slowing, reducing the demand for the country's exports so that NX = -80. (A negative value of net exports means that exports are less than imports.)
Instruction: Enter your response as an integer value.
Short-run equilibrium output (Click to select)increases/decreases to ___________ .
D. Which of the following best describes the tendency of recessions and expansions to spread across countries?
1. Lower planned aggregate spending in one nation will reduce the amount of goods it exports abroad, thereby lowering the value of imports for its trading partners, which will reduce its short-term equilibrium output as well.
2. Lower planned aggregate spending abroad means that fewer goods will be exported from a specific nation, leaving more goods available for domestic consumption (C) in that nation, which will increase its short-term equilibrium output.
3. Lower planned aggregate spending abroad will reduce the amount of investment that flows into domestic industries from other countries, thereby reducing domestic short-term equilibrium output.
4. Lower planned aggregate spending in a nation means fewer imports of foreign goods, thereby reducing the short-term equilibrium output of its trading partners through lower net export (NX) values in those nations.
