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.

BARTER A method of trading goods, commodities, or services, directly for one another without the use of money. Barter was the first type of market exchanged undertaken by human civilization as people advanced beyond self sufficiency in the satisfaction of their wants and needs. Modern economies still use a modest amount of barter to allocate resources. The key to a barter exchange is a double coincidence of wants, in which each side of the exchange wants what the other side has and has want the other side wants. A barter exchange tends to be less efficient that exchanges involving money.
