Natural Monopoly A market in which there is only room for one firm benefitting to the full, from economies of scale. Until recently utility companies were monopolies, until they were privatised in the 1980s.

Geographical Monopoly Single grocery store in a village or a single petrol station on a busy road. Local market of the store is too small for another shop.

Diagram Explained Shows a natural monopoly where because of limited market size there is only room for one firm benefitting from economies of scale. Economies of scale shown by downward sloping av cost curve. A monopoly is able to produce output Q1 at an average cost of C1. Whereas competitive firms are unable to produce at this output without destroying the competitive market.

Benefits of Monopolies The conclusion that a competitive market produces a better allocation of resources than a monopoly depends on the assumption that no or few economies of scale exist in a competitive market. When substantial economies of scale exist monopoly may lead to a better outcome than competition.

Further Benefit If the monopoly’s products are protected by economies of scale or a patent, competitors cannot free ride on its’ success. A monopoly can use their high profits to re-invest in R&D, producing new products.
