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.

MARKET STRUCTURE CONTINUUM The four common market structures, perfect competition, monopoly, monopolistic competition, and oligopoly, can be viewed as a continuum based on (1) differences in the number of firms in a market, (2) the relative size of each firm, and thus (3) the market control of each firm. Perfect competition lies at one end and monopoly at the other. Monopolistic competition is close to perfect competition and oligopoly is near monopoly. The essence of the continuum is that monopolistic competition blends into oligopoly, with no clear-cut line of separation.
