Question

Which of the following situations leads to an unplanned increase in inventories of $2.0 trillion? A. real GDP = $5.0 trillion and aggregate planned expenditures = $7.0 trillion B. real GDP = $5.0 trillion and aggregate planned expenditures = $5.0 trillion C. real GDP = $6.0 trillion and aggregate planned expenditures = $4.0 trillion D. real GDP = $8.0 trillion and aggregate planned expenditures = $5.0 trillion E. More information is needed about planned investment and actual investment.

Answer 1

Answer: C. real GDP = $6.0 trillion and aggregate planned expenditures = $4.0 trillion

Explanation:

Unplanned Inventory arises when Real GDP is larger than Planned Expenditure because it must satisfy the below formula,

Real GDP = Planned + Unplanned expenditure

For Option C,

Real GDP = 6.0 trillion,

Planned expenditure = 4.0 trillion

Unplanned Expenditure = Real GDP - Planned Expenditure

= $6.0 trillion - $4.0 trillion

= $2.0 trillion

Therefore Option C is correct as it led to a $2.0 trillion increase in Expenditure which translates to inventory.
