Expert Solution

A natural monopoly is a single firm in the market that can serve the entire market. The Average cost of the firm reduces continuously with increase in output and take advantages of economies of scale.

A monopoly firm usually produces where MR = MC in order to maximize its profit. However, this creates inefficiency in the market in the form of high deadweight loss. Also, both allocative efficiency (P = MC) and Productive Efficiency (P = Min ATC) are not achieved at the equilibrium.

To correct the situation, the government intervenes and forces the monopoly to reduce its price. Firm's profit are maximum where MR = MC. But government forces the natural monopolist to charge a price where P = minimum point of ATC. So, the firm earns normal profit in the long run. Such a price is called fair-return price.

The market becomes efficient with the regulation. However, only productive efficiency is achieved.

Natural monopoly firms are often regulated so that they can only charge prices set by the authorities. Under one approach, prices are based on the monopolist’s costs so that for any given quantity of sales, the monopolist can only set prices equal to its average costs. 1.
