Marginal benefit什麼意思

"Marginal benefit" is an economic term that refers to the additional benefit or utility that a consumer or individual receives from consuming one additional unit of a good or service. In other words, it is the change in total benefit that results from consuming one more unit of a product.

Marginal benefit is often used in decision-making processes, especially in relation to whether or not it makes sense to consume or purchase another unit of a good or service. If the marginal benefit of consuming an additional unit is greater than the marginal cost, then it may be considered worthwhile to consume or purchase that additional unit. However, as more units are consumed, the marginal benefit may begin to decrease, a concept known as diminishing marginal utility.

Marginal benefit is a key concept in microeconomics and is often used in the study of consumer behavior, welfare economics, and cost-benefit analysis.
