A consumer's indifference curves can never cross.

Question

Quizplus · Accepted Answer

Indifference curves represent a consumer's preferences, and they describe the combinations of two goods that provide the same level of satisfaction. Since a consumer cannot be indifferent between two different bundles of goods that provide different levels of satisfaction, indifference curves cannot cross. If they did cross, it would mean that a consumer is indifferent between two different levels of satisfaction, which is not possible in rational choice theory.
