Question

In an economy, when __________ is insufficient to achieve the level of output corresponding to the full employment, the difference is termed a deflationary gap. 
 

• A. ex-ante Aggregate Demand
• B. ex-post Aggregate Demand
• C. ex-ante Aggregate Supply
• D. ex-post Aggregate Supply

Hint:

A deflationary gap occurs when the economy's planned aggregate demand is not enough to achieve full employment. Always distinguish between ex-ante (planned) and ex-post (actual) values.

Answer 1

The Correct Option is A

Step 1: Understanding the concept.
A deflationary gap arises when aggregate demand is insufficient to reach the level of output that corresponds to full employment. This gap represents the shortfall in demand relative to the full capacity of the economy.
Step 2: Ex-ante vs. ex-post concepts.
- Ex-ante Aggregate Demand: This refers to the planned or intended level of aggregate demand in the economy before any real economic activities take place.
- Ex-post Aggregate Demand: This refers to the actual level of aggregate demand that occurs in the economy after the fact.
- Ex-ante Aggregate Supply: This is the planned supply of goods and services before actual economic activities.
- Ex-post Aggregate Supply: This is the actual supply of goods and services that results from economic activity.

Step 3: Conclusion.
The correct answer is (A) ex-ante Aggregate Demand, as a deflationary gap occurs when the planned demand falls short of the full employment output. Final Answer:} ex-ante Aggregate Demand.
