In the fourth place, statistics are usually compiled on a national basis, whereas relevant market areas are sometimes smaller or larger, differing from one industry to another [see Markets and industries].
The meaning and significance of concentration indexes are affected by practical as well as conceptual problems.
If the observed size distribution of firms in an industry fits well into a standard statistical distribution, a Lorenz curve is directly derived as the relation between the cumulative distribution function and first-moment distribution function of that cumulative distribution function.
Changes in concentration in British manufacturing between anda short period for most purposes, have also been examined with inconclusive results. That is, it will generally be convex upward. Arthur Monopoly in British Industry.
Observed density distributions of firm size are almost always unimodal and skewed upward: If defined on an establishment basis, value of output and similar data represent the total for all commodities produced by establishments assigned to the industry, assignment being based on the commodity of principal value in the establishment in question.
Comparative levels of concentration. Put the other way around, even though two industries have the same Herfindahl index, the numbers of firms, partial concentration ratios, and inequalities of firm size may differ Literature on industrial concentration many possible ways.
Similarly, significant differences in levels of concentration for the same industries over time or among countries at the same time provide important evidence on likely differences in pricing behavior.
In such a case, the concentration Literature on industrial concentration can be reproduced if the parameters of the distribution function are known along with the total number of firms. Beneath the stability lies a rapid turnover, displacement, and replacement of industries.
New York and London: Critic Leo Marx contended that, with the exception of apologists for the Southern slavery system, there was little effective opposition to the forces of urbanization and industrialism.
On the other side, there is the question of inequality of wealth and income in the economy as a whole. Not only have scholars concentrated on the canonical works by major authors of the period, but they have increasingly focused their attention on contemporary reactions found in magazines, newspapers, and popular novels in an effort to better understand the culture of the period.
In the second place, the systems of industrial classification used in basic statistical sources, especially in census-type materials, are not designed primarily for analysis of pricing behavior.
In recent years, between 14 and 18 per cent of national income in the United States has originated in highly concentrated industries, high concentration being defined in general by a four-firm concentration ratio of 50 per cent or more for industries at the four-digit level of classification Einhornp.
Most studies of concentration therefore deal only with these areas and, in fact, almost exclusively with manufacturing. For example, an industry may be defined on an establishment or on a product basis, or on the first basis for some purposes and the second for others.
The last is the inverse of a Literature on industrial concentration ratio, giving the number of leading firms required to account for a specified concentration ratio.
Moreover, a collection of curves would mean little without some theoretical framework for interpreting them. During the initial stages of the Industrial Revolution in England, the literati, for the most part, supported the new discoveries of science, often promoting their application in literary reviews.
The issue of economic concentration as it has emerged is essentially twofold in nature. Constructed in this way, the concentration curve is easily transformed into the well-known Lorenz curve by substituting relative for absolute numbers of firms on the horizontal axis—that is, by dividing the horizontal scale by the total number of firms see Figure 3.
The transfer of new technologies across the Atlantic also shaped the development of literature in the United States. In the first place, systematic and comprehensive statistics on industrial structure are limited primarily to the areas of manufacturing, mining, and public utilities. Economic Census Studies, No.
For analysis of industrial concentration, statistics should generally be compiled on a product basis, but this is not always possible. Unfortunately, no systematic theory of industrial structure has yet emerged from studies of this type to command broad agreement among professional economists.
Other factors are no doubt important in explaining industrial concentration, but they have not been clearly isolated by statistical analysis.
The normal interest has been stimulated from time to time by ascendance of various theories of history predicting that economies based on private enterprise must contain an inherent drift toward increasing economic concentration. The findings cannot be adequately summarized here, but a few broad generalizations can be drawn from them.
A final problem exists in matching firms with industries, a procedure that normally requires access to unpublished data. A Study of the Evolution of American Industry. Restrictions on disclosure of information about individual firms, a normal condition for most statistics collected and published by Western governments, also place limits on the kinds of indexes of concentration that can be computed.Agglomeration, Industrial Districts and Industry Clusters: Foundations of the 20th Century Literature Agglomeration, Industrial Districts and Industry Clusters focuses on the foundations laid by the early research on agglomerations, industrial districts, and industry clusters that was published in the 20th century.

Suttons work looks at the numbers of firms in the market and their shares of production in the market and the relationship between that in a different oligopoly models where a small number of firms controls the majority of the market share, the study also looks at the difference.
