Match the economic concepts in List-I with their corresponding definitions or representations in List-II.
Answer:
a-3, b-1, c-2, d-4
The utilitarian approach (a) is represented by the utility function U = f(x, y) (3). The ordinal approach (b) uses the marginal rate of substitution (1). The price consumption curve (c) is derived from the budget line and indifference curves (2). Consumer equilibrium (d) occurs where the marginal rate of substitution equals the ratio of prices (MRSxy = Px/Py) (4).
172
What is the status of total utility when the marginal utility of a good is zero?
Answer:
Total utility is maximised
Marginal utility is the change in total utility derived from consuming one additional unit. When marginal utility is zero, the consumer has reached the point of satiation. Consuming more would not add to total satisfaction, meaning total utility is at its peak or maximum level at that specific point.
173
Which of the following best describes the synthesis reflected in J.R. Hicks' Indifference Curve Analysis?
Answer:
Marshall's theory with Pareto's method
J.R. Hicks' indifference curve analysis is often described as an attempt to provide a more rigorous foundation for Marshallian demand theory by utilizing the ordinal utility approach pioneered by Vilfredo Pareto. It replaces the cardinal utility assumptions of Marshall with the ordinal ranking of preferences, effectively combining Marshallian objectives with Paretian methodology.
174
The Law of Equimarginal Utility is known by several alternative names. Which of the following is NOT a recognized synonym for this principle?
Answer:
Law of utility and demand
The Law of Equimarginal Utility, also known as the Law of Substitution, the Law of Maximum Satisfaction, or the Law of Economy in Expenditure, states that a consumer maximizes utility when the marginal utility per dollar spent is equal across all goods. 'Law of utility and demand' is not a standard technical name for this principle, making it the correct choice for the mismatch.
175
Which conditions must be satisfied for a consumer to be at equilibrium?
Answer:
(ii) and (iii)
Consumer equilibrium occurs when a consumer maximizes utility given their budget constraint. This is achieved at the point where the budget line is tangent to the highest attainable indifference curve. Note: The provided answer key suggests (ii) and (iii), though standard theory emphasizes (i) and (ii).
176
For a consumer purchasing multiple commodities (X, Y, and Z), what condition must be met to maximize total satisfaction?
Answer:
$$\frac{{M{U_x}}}{{{P_x}}} = \frac{{M{U_y}}}{{{P_y}}} = \frac{{M{U_z}}}{{{P_z}}}$$
According to the Law of Equi-marginal Utility, a consumer maximizes satisfaction when the marginal utility per dollar spent is equal across all goods consumed. This ensures that the last unit of currency spent on each commodity provides the same level of additional utility.
177
Which of the following equations correctly represents the relationship between price, income, and substitution effects?
Answer:
Price effect = Income effect + Substitute effect
The Slutsky equation demonstrates that the total change in quantity demanded resulting from a price change (the price effect) is the sum of the substitution effect (change due to relative price changes) and the income effect (change due to the change in real purchasing power).
178
What is the status of marginal utility when a consumer reaches the point of satiety?
Answer:
Zero
The point of satiety represents the level of consumption where total utility is at its absolute maximum. At this specific point, the additional satisfaction gained from consuming one more unit of a good, known as marginal utility, becomes zero. Consuming beyond this point would lead to negative marginal utility, as total utility would begin to decline.
179
What does an indifference curve represent?
Answer:
Different combination of two goods among which the consumer is indifferent
An indifference curve is a graphical representation showing various combinations of two goods that provide the consumer with the same level of satisfaction or utility. Because the consumer derives equal satisfaction from any point on the curve, they are indifferent between those combinations.
180
Which of the following is NOT a fundamental property of standard indifference curves?
Answer:
Indifference curves of two imperfect substitutes are concave to the point of origin
Standard indifference curves are convex to the origin, not concave. Convexity reflects the principle of diminishing marginal rate of substitution, meaning consumers prefer balanced bundles of goods. Concave curves would imply an increasing marginal rate of substitution, which contradicts typical consumer behavior where individuals prefer variety over extreme consumption of a single good.
