Term marginal utility and demand Definition: An explanation of the law of demand and the negatively-sloped demand curve can be found in the analysis of marginal utility and especially the law of diminishing marginal utility. This explanation rests on two propositions. One, the law of diminishing marginal utility means that the marginal utility obtained from consuming a good declines as the quantity consumed increases. Two, the marginal utility of a good underlies the demand price that buyers are willing and able to pay for a good. When combined, these two propositions indicate that the demand price buyers are willing and able to pay for a good declines as the quantity demanded (and consumed) increases. And this is the law of demand.
