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.

Although firms might not seek to maximize profit on a day-to-day basis, those that come closest (intentionally or unintentionally) are the ones that remain in business.

Big Ott's has a large sign prominently posted at the entry to his establishment. It screams in no uncertain terms: NO PEDESTRIANS ALLOWED. As a well-known, card-carrying pedestrian, I am, to say the least, taken aback. Why on earth would Big Ott's Boiled Burger Buffet refuse service to pedestrians? A quick quiz of an employee reveals that Big Ott once swerved off the sidewalk to avoid striking a pedestrian, causing extensive damage to his sleek, new OmniMotors XL GT 9000 convertible sport coupe. His anger has been since extended to all who travel by foot.
