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.

LEGAL RESERVES

The combination of vault cash and Federal Reserve deposits that banks can legally use to satisfy government reserve requirements. Legal reserves, which can also be considered total reserves, are divided between require reserves and excess reserves. Required reserves are used to back up deposits and process daily transactions, while excess reserves are then available for interest-paying loans.
