In other words, for an industry to remain concentrated or monopolized there has to be some way to close the market to entry. However, these indices must be interpreted with care.
One way of describing the competitive structure of different industries is presented in Table 3. Currently, the top four producers of breakfast cereal account for about 90 percent of the breakfast cereal sold in the United States, and the top eight account for almost percent of the breakfast cereal sold in the United States.
Thus, the information in Table 3.
Firms in these industries generate, at best, returns that just cover their cost of capital in the long run, and social welfare as traditionally defined in economics is maximized. Thus, the monopoly profits are likely to be reduced, if not completely eroded, by structural changes.
Column 1 of Table It has made an in-depth study of the theory and practice of commodity pricing and output determination under different market conditions — pure competition, pure monopoly and imperfect competition.
Social welfare is maximized in perfectly competitive industries, it is somewhat lower in monopolistically competitive industries, it is somewhat lower still in oligopolies, and it is very low in monopolies. The existence of scale economies invariably increases the profitable scale of operation of the firm.
This is a paradigm that is foundational to industrial organization economics, consistent with the positional view of strategy, as opposed to the resource-based view of strategy. One major facet of the paradigm that bears real significance is the relationship, if any, between concentration and profits.
If one of the large firms in the industry increases its output while the other do not, there will be a rise- in the value of H indicating that there is greater concentration in the industry now. Conduct, in its turn, determines performance or the degree to which certain ideal macroeconomic goals are attained.
Still other industries can be described as oligopolies. The logic that links industry structure to conduct and performance is well known. At the two extremes, zero per cent of firms make zero per cent of the total sales, and per cent of the firms sell per cent of the total output. Even when firms have more conduct options, industry structure still constrains the range of those options.
The shape of the long run average cost curve depends on economies and diseconomies of scale. This view gets ample support from both the proponents and opponents of monopoly.
Firms in oligopolistic industries can earn significant economic profits. The regulatory implications of the S-C-P paradigm depend on the level of social welfare associated with each of the types of competition presented in Table 3.
But this view has to be evaluated critically. We may now illustrate, for the simplest case of absolute cost advantages, the degree by which prices can be raised without attracting new entry. We may discuss the third barrier, listed by Bain as absolute cost advantage, which refers to any cost difference that favours established firms.

Firms in such industries have a variety of conduct options and can gain competitive advantages. The reason is easy to find. This obviously clashes with the objective of industrial growth. Additionally, external factors such as legal or political interventions affect the market framework and, by extension, the structure, conduct and performance of the market.
They are watched closely by the appropriate authorities. If, for instance, multi plant scale economies are minimal, while the minimal efficient scale MESthe point at which the LARC ceases to decline, occurs at a low level of output, then we would expect to observe a large number of single plant, rather than a few multi- plant, firms.

Thus, even in this case, industry structure still has an important effect on firm conduct and firm performance even though firms in these industries can sometimes have competitive advantages.
Mason and Joe S. Economies of Scale in Market Structure: For instance, if we had drawn Figure In this interactive presentation--one in a series of multimedia frameworks--McKinsey director emeritus John Stuckey comments on SCP, a framework that illustrates the influence of an industry's structure on the conduct and performance of industry players, and the effects of external shocks on all three.
The market structure indirectly affects business conduct inasmuch as the components of market structure (such as the number of buyers and sellers, the firm’s influence over price etc.) determine, at least partly, the pricing strategy a firm can follow. The structure-conduct-performance (SCP) hypothesis states that a decrease in the number of firms within a market may lead to collusion among firms, while the relative market power hypothesis states that firms that accrue market power may use this power adversely for consumers (e.g., to raise price and increase profit).
Structure, conduct, performance paradigm Structure, Conduct and Performance paradigm (SCP) is used as an analytical framework, to make relations amongst market structure, market conduct and market performance.
The structure–conduct–performance (SCP) paradigm, first published by economists Edward Chamberlin and Joan Robinson inand developed by Joe S. Bain is a model in Industrial Organization Economics which offers a causal theoretical explanation for firm performance through economic conduct on incomplete markets.
Market structure conduct and performance (SCP) framework was derived from the neo- classical analysis of markets. The SCP paradigm was the brain child of the Harvard.Download
