In the aggregate expenditure (AE) model, the economy is driven to its equilibrium by changes in O a. government expenditures on goods and services that are the result of changes in real GDP. O b. autonomous expenditures that are the result of changes in real GDP. O C. investment that are the result of changes in real GDP. O d. induced expenditures that are the result of changes in real GDP.

Quèstion 5 $60 $40 -- $20 $50 100 150 200 Disposable Income(Y) -20 Refer to the diagram. The average propensity to consume: O A. is greater than 1 at all levels of disposable income above $100. O B. cannot be determined from the information given. O C, is equal to the average propensity to save. O D. is greater than 1 at all levels of disposable income below $100. Saving (S)

If taxes fall and government spending rises by the same amount, there is very little change in GDP. O True O False

1. Aggregate expenditures and income The following table shows consumption (C), investment (1), government spending (G), and net exports (X-M) in a hypothetical economy for various levels of real GDP (Y). Assume that the price level remains unchanged at all levels of income. All figures are in billions of dollars. Compute aggregate expenditures for each income level and fill in the last column In the following table.

Imagine a 45°-line (Keynesian cross) diagram in which the upward-sloping aggregate expenditure curve intersects the 45°-line at point A. The economy is currently in macroeconomic equilibrium at output level Y.. Suppose that the price level increases. If the price level increases, the aggregate expenditures line will shift down The new equilibrium levels of GDP and expenditures will be O A. where the new AE line intersects the 45°-line. O B. unchanged. OC. anywhere on the new AE line ⒸD. where the new AE line interesects the original AE line.

Assume that MPS is 0.4. If spending increases by $8 billion, then real GDP will increase by Multiple Choice O O O O $15 billion. $20 billion. $13.3 billion. $8 billion.

Moving to another question will save this response. Question 8 In an open mixed economy, the inflationary expenditure gap may be described as the O A. excess of GDP over Ca + lg +Xn +G at the full-employment output. O B. excess of Sa + M +T over lg +X+ G at the full-employment GDP. O C. excess of Ca + lg +Xn + G at the full-employment GDP. O D.extra consumption that occurs when investment increases in a full-employment economy. A Moving to another question will save this response.

Quèstion 1 In an open mixed economy, the inflationary expenditure gap may be described as the O A. excess of Sa + M+T over lg + X+ G at the full-employment GDP. O B. excess of GDP over Ca + lg +Xn + G at the full-employment output. OC excess of Ca + Ig + Xn + G at the full-employment GDP. O D. extra consumption that occurs when investment increases in a full-employment economy.

Suppose that the level of GDP increased by $100 billion in an economy where the marginal propensity to consume is 0.5. The initial change in spending must have been: O $5 billion O $100 billion O $50 billion O $500 billion
