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.

No-reserve banking is one of two theoretical alternatives designed to help illustrate a contrast to the fractional-reserve banking actually practiced by modern banks. The other alternative is full-reserve banking. With the no-reserve approach a bank operates as financial intermediary or broker, matching up borrowers and lenders.
