ENTRY BARRIER: 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.
