Marginal utility is a Cardinal Concept

Cardinal utility is a concept in economics that refers to the measurement of the satisfaction or utility that consumers derive from the consumption of goods and services. It is a quantitative concept that assigns numerical values to the level of utility or satisfaction that a consumer derives from consuming a particular good or service. Cardinal utility is measured in utils, a hypothetical unit of measurement that reflects the level of satisfaction or utility that a consumer derives from consuming a particular good or service.

Marginal utility is a concept that is closely related to cardinal utility. It refers to the additional utility or satisfaction that a consumer derives from consuming an additional unit of a good or service. Marginal utility is also measured in utils and is used to determine the optimal level of consumption of a good or service.

Ordinal utility, on the other hand, is a concept that does not assign numerical values to the level of utility or satisfaction that consumers derive from the consumption of goods and services. Instead, it ranks the level of satisfaction or utility that consumers derive from different goods or services in order of preference.

Therefore, since marginal utility is a quantitative concept that assigns numerical values to the level of utility or satisfaction that consumers derive from consuming an additional unit of a good or service, it is a cardinal concept.
