Indifference Curve Property Analysis

This section identifies the valid properties of indifference curves relevant to microeconomic analysis.

Property A: Downward Slope

Statement: Indifference curve slopes downward to right.

Analysis: This property holds true. To maintain the same level of satisfaction, if a consumer increases consumption of one good, they must decrease consumption of the other.

Property B: Concavity

Statement: Indifference curve is concave to origin.

Analysis: This statement is incorrect. Standard indifference curves exhibit convexity, not concavity.

Property C: Convexity

Statement: Indifference curve is convex to origin.

Analysis: This property is correct. Convexity implies that the marginal rate of substitution (MRS) diminishes as the consumer moves down the curve, meaning they are willing to give up less of one good to obtain more of the other.

Property D: Non-Intersection and Tangency

Statement: Indifference curves cannot intersect each other but can be tangent to each other.

Analysis: While indifference curves representing the same consumer cannot intersect, the statement that they "can be tangent to each other" is incorrect. Indifference curves represent distinct levels of satisfaction and do not touch or become tangent to one another. Therefore, this statement is false.

Property E: Higher Curve, Higher Satisfaction

Statement: Higher indifference curve represents higher level of satisfaction.

Analysis: This property is correct. Assumptions of consumer theory state that more is preferred to less; hence, a higher indifference curve signifies a greater bundle of goods and thus higher utility.

Conclusion

The correct properties of an indifference curve are A, C, and E. This aligns with option 3.
