Answer 4

A monopoly exists where there is a single provider of a commodity for which there are not close substitutes and where entry into the market is difficult. Natural monopolies exist where there is increasing return to scale of operations and is justified by a single entity being able to satisfy demand at a lower cost than two or more firms. Public utilities have been cited traditionally as examples of natural monopolies.

Oligopoly market. In an oligopoly market, there are few providers of goods or services. In a monopoly there is only one provider; in a perfect competition or monopolistic competition there are many providers.
