Which equation represents the macroeconomic equilibrium condition in the aggregate expenditure (AE) model?
Explain, in detail, how the adjustment to macroeconomic equilibrium occurs when spending is less than production. Be sure to discuss how inventories play a crucial role in the adjustment process. State what happens to GDP and employment during the adjustment process.
Consider the table on the right, which shows business
investment in inventories for each quarter from the first
quarter of 2007 to the first quarter of 2012, measured in
millions of 2007 dollars. Provide a macroeconomic
explanation for this pattern. (Hint: When did the recession
during this period begin and end?)
The negative growth of inventories indicates a period of
OA. inflation since inventories needed to be reduced
in the face of increasing storage cost
OB. recession because demand was met by drawing
down past inventories and production did not
increase.
OC. recovery since inventories needed to be used to
meet demand.
OD. recession because inventories increased due to
lack of demand
