Question

From the above diagram, identify the point which is inferior for a consumer with respect to the indifference curve and budget line.

• A. Point A
• B. Point D
• C. Point B
• D. Point C

Hint:

Interior points of a budget set represent underutilization of income and lie on lower indifference curves, making them inferior to boundary points.

Answer 1

The Correct Option is A

Concept:
Consumer equilibrium analysis via ordinal utility compares budget constraints against consumer preferences represented by indifference curves.
Higher indifference curves represent higher levels of satisfaction, while points lying strictly below the budget line represent inferior or suboptimal consumption bundles.

Step 1: Evaluation of the Diagrammatic Points:
In the standard consumer choice diagram:
- Point B lies at the point of tangency between the budget line and the highest attainable indifference curve, representing the optimal utility-maximizing bundle.
- Point C lies directly on the budget line, exhausting consumer income, but lies on a lower indifference curve than point B.
- Point D lies on an indifference curve situated above the budget line, representing a bundle that is preferred but currently unaffordable.
- Point A lies strictly inside the budget set (below the budget line) and rests on a significantly lower indifference curve than the attainable frontier points.

Step 2: Identifying the Inferior Point:
Because Point A fails to exhaust the consumer's available income and yields a lower level of total satisfaction compared to any bundle on the budget line, it is designated as an inferior bundle.
Final Answer:
Point A is the inferior point with respect to both the budget line and indifference curves. Hence, option (A) is correct.
