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.
A full oligopoly is one in which a price leader is not present in the market, and where firms enjoy relatively similar market control. A partial oligopoly is one where a single firm dominates an industry through saturation of the market, producing a high percentage of total output and having large influence over market conditions.
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 ...
An oligopoly usually has "economic profit" also, but usually faces an industry/market with more than just one firm (they must share available demand at the market price). Economic profit is much more prevalent in uncompetitive markets such as in a perfect monopoly or oligopoly situation, where few substitutes exit
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).
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.
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.
The principal difference between short run and long run profit maximization is that in the long run the quantities of all inputs, including physical capital, are choice variables, while in the short run the amount of capital is predetermined by past investment decisions. In either case, there are inputs of labor and raw materials.
