makvit [3.9K]

Occasionally, barriers to entry may lead to pure monopoly; in other market conditions, they may limit competition to a few oligopoly firms

<h3>Do barriers to entry exist in a pure monopoly?</h3>

Due to entrance restrictions that deter prospective rivals, firms acquire monopolistic power. Barriers to entry, or conditions that make it difficult or impossible for potential competitors to participate in the market, give monopolies their market strength.

The four main elements of monopoly are: (1) a single business controlling the entire output of a market; (2) a distinctive product; (3) barriers to admission and departure from the industry; and, frequently (4) specialised knowledge about production methods that are not available to other potential producers.
