Question

Quizplus · Accepted Answer

When there is no budget constraint, the consumer can consume as much as they want of any good. In this case, the consumer will maximize their utility by consuming the goods that give them the highest marginal utility. Marginal utility is the additional satisfaction that a consumer gets from consuming one more unit of a good. If the marginal utility of a good is zero, then the consumer is not getting any additional satisfaction from consuming more of that good. Therefore, the consumer will maximize their utility by consuming the goods that have the highest marginal utility, which is when the marginal utility is zero.
