PARETO EFFICIENCY: A type of efficiency that results if one person can not be made better off without making someone else worse off. Named after Vilfredo Pareto, this criterion is the guiding theoretical notion of efficiency used in the study of economics, especially welfare economics. Pareto efficiency is generally not attained if some resources are idle or unemployed. By engaging idle resources in production, some people can have more production without reducing that available to others. A problem with Pareto efficiency, however, is that it is based on the existing distribution of income and wealth. This is one of two noted efficiency criteria used in economics. The other is Kaldor-Hicks efficiency.

The money function in which money is used as a means of postponing the satisfaction obtained from using or consuming goods until a later time. Value is obtained from a good when it is consumed, when it is used to satisfy wants and needs. The value from consuming goods can be stored in several different ways, one of which is money. This is one of four basic functions of money. The other three are medium of exchange, unit of account, and standard of deferred payment.
