Law of Diminishing Marginal Utility

In economics, the theory that for each additional unit of a product an individual consumes, the less utility or satisfaction the person derives from it. This is important to determining how much supply of a product the market can handle without diminishing demand. Historically, it has been thought that one can quantify the marginal utility of each unit, but some economists disagree with this. See also: Austrian school.
