Скачать или смотреть Barriers to entry

In theories of competition in economics, barriers to entry, also known as barrier to entry, are obstacles that make it difficult to enter a given market. The term can refer to hindrances a firm faces in trying to enter a market or industry—such as government regulation and patents, or a large, established firm taking advantage of economies of scale—or those an individual faces in trying to gain entrance to a profession—such as education or licensing requirements.
Because barriers to entry protect incumbent firms and restrict competition in a market, they can contribute to distortionary prices. The existence of monopolies or market power is often aided by barriers to entry.
