In small countries like New Zealand, electricity transmission is a natural monopoly. Due to enormous fixed costs and small market size, one seller can serve the entire market at the downward-sloping section of its average cost curve, meaning that it will have lower average costs than any potential entrant.
A monopoly produces where its average cost curve meets the market demand curve under average cost pricing, referred to as the average cost pricing equilibrium. Minimum efficient scale: Marginal or average costs may be nonlinear, or have discontinuities. Average cost curves may therefore only be shown over a limited scale of production for a ...
The rule was later applied by Marcel Boiteux (1956) to natural monopolies (industries with decreasing average cost). A natural monopoly earns negative profits if it sets price equals to marginal cost, so it must set prices for some or all of the products it sells to above marginal cost if it is to be viable without government subsidies.

A natural monopoly is an organization that experiences increasing returns to scale over the relevant range of output and relatively high fixed costs. [70] A natural monopoly occurs where the average cost of production "declines throughout the relevant range of product demand".
The emergence of oligopoly market forms is mainly attributed to the monopoly of market competition, i.e., the market monopoly acquired by enterprises through their competitive advantages, and the administrative monopoly due to government regulations, such as when the government grants monopoly power to an enterprise in the industry through laws ...
The company is able to collect a price based on the average revenue (AR) curve. The difference between the company's average revenue and average cost, multiplied by the quantity sold (Qs), gives the total profit. A short-run monopolistic competition equilibrium graph has the same properties of a monopoly equilibrium graph.
But, as a natural monopoly, PG&E and other investor-owned utilities do not have to be for-profit entities. In fact, around California, there are over 40 publicly owned electric utilities that are ...
