Moving along an indifference curve the
A) marginal rate of substitution is constant.

C) marginal rate of substitution is equal to 0.
D) consumer prefers some of the consumption points to others.
E) marginal rate of substitution for a good increases as more of the good is consumed.

Question

Quizplus · Accepted Answer

Moving along an indifference curve implies that the consumer is indifferent between the consumption points, meaning they do not prefer one point over another. The marginal rate of substitution (MRS) changes along the curve, reflecting the rate at which a consumer is willing to substitute one good for another while maintaining the same level of utility, hence A, C, and E are incorrect. D is incorrect because it contradicts the definition of an indifference curve, where all points are of equal preference to the consumer.
