In economics, marginal utility describes the change in utility (pleasure or satisfaction resulting from the consumption) of one unit of a good or service. [ 1] Marginal utility can be positive, negative, or zero. Negative marginal utility implies that every additional unit consumed of a commodity causes more harm than good, leading to a ...
v. t. e. Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water.
One use of the indirect utility concept is the notion of the utility of money. The (indirect) utility function for money is a nonlinear function that is bounded and asymmetric about the origin. The utility function is concave in the positive region, representing the phenomenon of diminishing marginal utility. The boundedness represents the fact ...
The theory of marginal utility, which is based on the subjective theory of value, says that the price at which an object trades in the market is determined neither by how much labor was exerted in its production nor on how useful it is on the whole. Rather, its price is determined by its marginal utility. The marginal utility of a good is ...

Irving Fisher described Jevons's book A General Mathematical Theory of Political Economy (1862) as the start of the mathematical method in economics. [ 3] It made the case that economics, as a science concerned with ...
The elasticity of intertemporal substitution is defined as the percent change in consumption growth per percent increase in the net interest rate: By substituting in our log equation above, we can see that this definition is equivalent to the elasticity of consumption growth with respect to marginal utility growth: Either definition is correct ...
Indifference curve. In economics, an indifference curve connects points on a graph representing different quantities of two goods, points between which a consumer is indifferent. That is, any combinations of two products indicated by the curve will provide the consumer with equal levels of utility, and the consumer has no preference for one ...
