Document Summary

A single firm that produces a good or service with no close substitutes. Protected from competition by a barrier to entry that prevents other firms from entering that market. Natural barrier to entry creates a natural monopoly a market in which economies of scale enable one firm to supply the entire market at the lowest possible cost. E. g. one firm can distribute 4mil kilowatt-hours at 5 cents per kilowatt-hour while this same output costs 10 cents a kilowatt-hour with two firms (produce 2mil each) Ownership barrier to entry occurs if one firm owns a significant portion of a key resource. Legal barrier to entry creates a legal monopoly a market in which competition and entry are restricted by the granting of: A public franchise: exclusive right granted to a firm to supply a good/service. Government license: controls entry into particular occupations and industries. Patent: exclusive right granted to the inventor. Copyright: exclusive right granted to the author or composer.
