Explanation:
A monopoly is when there's only one firm operating in an industry.
Economies of scale is cost reduction that accures to a firm as a result of its large scale production. For example, a supplier might give a producer a discount for buying in bulk.
A patent is when the government or an agency of the government gives the right to produce an invention or a good for a set period, others are usually excluded making, using or selling the invention.
Copyright gives the owner of an intellectual property the exclusive right to make copies of a creative work, usually for a limited time.
If a firm has exclusive access to resocurces, it is possible for the firm to prevent other firms from entering into the industry and thus retain monopoly power.
