In ethics, value denotes the degree of importance of something or action, with the aim of determining what actions are best to do or what way is best to live or to describe the significance of different actions.
1. Accounting: The monetary worth of an asset, business entity, good sold, service rendered, or liability or obligation acquired.
2. Economics: The worth of all the benefits and rights arising from ownership. Two types of economic value are (1) the utility of a good or service, and (2) power of a good or service to command other goods, services, or money, in voluntary exchange.
3. Marketing: The extent to which a good or service is perceived by its customer to meet his or her needs or wants, measured by customer’s willingness to pay for it. It commonly depends more on the customer’s perception of the worth of the product than on its intrinsic value.
4. Mathematics: A magnitude or quantity represented by numbers.
