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.

FACTORY

The physical capital (building and equipment) at a particular location used for the production of goods and services. A factory, or plant, is usually a relatively large production operation (compared with something smaller, like a shop). While factory and firm are occasionally used synonymously they are not really the same. A given firm might own more than factory and a given factory might be owned by more than one firm.
