What is utility?

Utility is a term used in economics to describe the satisfaction or benefit that a consumer receives from consuming a good or service. It is a measure of the level of happiness or fulfillment that a person derives from consuming a particular product or service. Utility is subjective and can vary from person to person, as different individuals may derive different levels of satisfaction from the same good or service.

- Ordinal: Utility can be ranked in order of preference (e.g., I like A more than B), but it cannot be measured in absolute terms.
- Marginal: The marginal utility is the additional satisfaction obtained from consuming one more unit of a good or service.
- Diminishing: As more units of a good or service are consumed, the marginal utility typically diminishes.
