Economics Utility Concepts Matching Quiz Solution Explained
This question requires matching fundamental concepts in consumer theory, specifically related to utility analysis. Let's break down each item in List-I and find its corresponding definition in List-II.
Matching List-I with List-II Concepts
-
(A) Analysis assumes that level of utility can be expressed in numbers.
This statement describes a scenario where economists believe that the satisfaction or utility a consumer derives from a good or service can be measured quantitatively, using numerical values. This approach is known as Cardinal Utility.
- Matches with: (I) Cardinal Utility
-
(B) Change in total utility due to consumption of one additional unit of a commodity
This definition refers to the extra satisfaction gained from consuming one more unit of a product. Economists call this the Marginal Utility.
- Matches with: (III) Marginal Utility
-
(C) Marginal utility from consuming each additional unit of a commodity declines as its consumption increases.
This principle states that as a consumer consumes more and more units of a specific good, the additional satisfaction (marginal utility) obtained from each subsequent unit tends to decrease. This is a core concept known as the Law of Diminishing Marginal Utility.
- Matches with: (II) Law of Diminishing Marginal Utility
-
(D) The amount of mangoes that the consumer has to forego in order to get an additional banana, her total utility level being the same.
This describes the rate at which a consumer is willing to trade one good for another while maintaining the same level of overall satisfaction. This concept is specifically defined as the Marginal Rate of Substitution.
- Matches with: (IV) Marginal rate of substitution
Correct Matching
Based on the explanations above, the correct pairings are:
- (A) - (I) Cardinal Utility
- (B) - (III) Marginal Utility
- (C) - (II) Law of Diminishing Marginal Utility
- (D) - (IV) Marginal rate of substitution
Therefore, the correct option is (A) - (I), (B) - (III), (C) - (II), (D) - (IV).
