    Definition of Monopoly

    Monopoly: a market with a single seller who sells a unique product that no other firms can produce.

    A Monopoly is a market which has the following two features:

    1. No Close Substitute: If one or more firms can produce a close substitute, then the single seller will face competition from the producers of the substitute.

    2. Barrier to Entry: are constraints that prevent or makes it extremely difficult for new firms to enter the market.

    Barriers to Entry:

    There are 3 types of barriers to entry:

    1. Natural Barrier to Entry: Economies of Scale causes one firm to be able to supply the entire market at the lowest possible cost. A natural barrier to entry creates natural monopoly.

      Monopoly natural barrier to entry
      Note: The firm realizes from the LRAC that the more outputs they produce, the lower the cost for each unit. Hence, they supply the entire market.

    2. Ownership Barrier to Entry:occurs when one firm owns a huge portion of a resource that is used to produce the good.

    3. Legal Barrier to Entry:a barrier where competition and entry are restricted by the granting of:

      1. Public franchise: exclusive right granted to a firm to supply a good or service
      2. Government license: controls entry into specific jobs, or industries
      3. Patent: exclusive right given to the inventor of a good
      4. Copyright: exclusive right given to an author or composer.

    Methods to Setting Prices to Monopoly:

    In a monopoly, the firm can set its own prices. However, they also know that the amount of quantity produces changes the market price. There are two methods to setting prices to buyers:

    1. Single-Price Monopoly: the firm sells each unit of output for the same price to all buyers.

    2. Price Discrimination: the firms sell their unit of output for difference prices to different buyers.

      Note: When firms price discriminates, their motive is to charge the highest possible price for each unit sold to gain the most profit.
