BARRIER TO ENTRY: An institutional, government, technological, or economic restriction on the entry of firms into a market or industry. The four primary barriers to entry are: resource ownership, patents and copyrights, government restrictions, and start-up costs. Barriers to entry are a key reason for market control and the inefficiency that this generates. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.

VALUE ADDED

The increase in the value of a good at each stage of the production process. The "value" part of this phrase means the ability of a good to satisfy wants and needs either directly as a consumption good or indirectly as a capital good. The "added" part means that resources have transformed the good in the course of production, to make it more valuable. A good that provides greater satisfaction has greater value.
