One form of collusive oligopoly is a cartel, [18] [better source needed] a monopolistic organisation and relationship formed by manufacturers who produce or sell a certain kind of goods in order to monopolise the market and obtain high profits by reaching an agreement on commodity price, output and market share allocation. However, the ...
Marshall's original introduction of long-run and short-run economics reflected the 'long-period method' that was a common analysis used by classical political economists. However, early in the 1930s, dissatisfaction with a variety of the conclusions of Marshall's original theory led to methods of analysis and introduction of equilibrium notions.
Cournot's economic theory was little noticed until Léon Walras credited him as a forerunner. This led to an unsympathetic review of Cournot's book by Joseph Bertrand which in turn received heavy criticism. Irving Fisher found Cournot's treatment of oligopoly "brilliant and suggestive, but not free from serious objections". [5]
Here too the profit is not maximized and the firm has to lower its output level to maximize profits. In economics, profit maximization is the short run or long run process by which a firm may determine the price, input and output levels that will lead to the highest possible total profit (or just profit in short).
In oligopoly theory, conjectural variation is the belief that one firm has an idea about the way its competitors may react if it varies its output or price. The firm forms a conjecture about the variation in the other firm's output that will accompany any change in its own output.
Companies do not make any economic profits in a perfectly competitive market once it has reached a long run equilibrium. If an economic profit was available, there would be an incentive for new firms to enter the industry, aided by a lack of barriers to entry, until it no longer existed. [6] When new firms enter the market, the overall supply ...
Examples are Cournot oligopoly, and Bertrand oligopoly for differentiated products. Bain's (1956) original concern with market concentration was based on an intuitive relationship between high concentration and collusion which led to Bain's finding that firms in concentrated markets should be earning supra-competitive profits.
Abnormal profit persists in the long run in imperfectly competitive markets where firms successfully block the entry of new firms. [3] Abnormal profit is usually generated by an oligopoly or a monopoly ; however, firms often try to hide this fact, both from the market and government, in order to reduce the chance of competition, or government ...
