Answer to Question 1

a. If real GDP equals 10 trillion, aggregate expenditure exceeds GDP and so firms' inventories are less than planned.
b. If real GDP equals 20 trillion, aggregate expenditure is less than GDP and so firms' inventories are more than planned.
c. The equilibrium level of expenditure is 15 trillion because at this level of GDP, aggregate expenditure equals GDP. As a result, firms' inventories equal planned inventories so firms have no incentive to either increase or decrease production.
