The correct sequence of the market structure from most to least competitive is perfect competition, imperfect competition, oligopoly, and pure monopoly. The main criteria by which one can distinguish between different market structures are: the number and size of firms and consumers in the market, the type of goods and services being traded ...
An oligopoly (from Ancient Greek ὀλίγος (olígos) 'few' and πωλέω (pōléō) 'to sell') is a market in which pricing control lies in the hands of a few sellers. [ 1 ] [ 2 ] As a result of their significant market power, firms in oligopolistic markets can influence prices through manipulating the supply function .
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.
A monopoly has considerable although not unlimited market power. A monopoly has the power to set prices or quantities although not both. [37] A monopoly is a price maker. [38] The monopoly is the market [39] and prices are set by the monopolist based on their circumstances and not the interaction of demand and supply. The two primary factors ...
The diagram on the right illustrates both effects, using the standard approach based on the notion of economic surplus. According to this notion, the workers' economic surplus (or net gain from the exchange) is given by the area between the S curve and the horizontal line corresponding to the wage, up to the employment level.
It is a particular case of oligopoly, so it can be said that it is an intermediate situation between monopoly and perfect competition economy. Hence, it is the most basic form of oligopoly . [ 4 ]
A monopolist can set a price in excess of costs, making an economic profit. The above diagram shows a monopolist (only one firm in the market) that obtains a (monopoly) economic profit. An oligopoly usually has economic profit also, but operates in a market with more than just one firm (they must share available demand at the market price).
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 ...
