A natural monopoly is a monopoly in an industry in which high infrastructural costs and other barriers to entry relative to the size of the market give the largest supplier in an industry, often the first supplier in a market, an overwhelming advantage over potential competitors. Specifically, an industry is a natural monopoly if the total cost ...
The Ramsey problem, or Ramsey pricing, or Ramsey–Boiteux pricing, is a second-best policy problem concerning what prices a public monopoly should charge for the various products it sells in order to maximize social welfare (the sum of producer and consumer surplus) while earning enough revenue to cover its fixed costs.
The monopoly ensures a monopoly price exists when it establishes the quantity of the product. [1] As the sole supplier of the product within the market, its sales establish the entire industry's supply within the market, and the monopoly's production and sales decisions can establish a single price for the industry without any influence from ...

The value of the index ranges from 1/N to 1 (where N is the number of firms in the market). Thus, the more concentrated the market is, the larger the value of the Herfindahl Index will be. [ 4 ] The table below provides an overview of price competition and intensity in the four main classes of market structure.
The clearest example is a monopoly, where a single producer has complete control over supply and can extract a monopoly price. An oligopoly - a small number of producers - can also sustain an undersupply if no producers attempt to gain market share with lower prices at higher volume. Lack of supply competition can arise in many different ways:
