ENTRY BARRIERS: Institutional, government, technological, or economic restrictions 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.

ECONOMIC RESOURCE

A resource with an available quantity less than its desired use. Economic, or scarce, resources are also called factors of production and generally classified as either labor, capital, land, or entrepreneurship. Economic resources are the workers, equipment, raw materials, and organizers that are used to produce economic goods. Like the more general society-wide condition of scarcity, a given resource falls into the economic or scarce category because of it has a limited availability relative to (potentially unlimited) productive uses.
