Abstract

The leading element of market structure, the market share of the firm is a simple fact which is central to the study of industrial organization. Because it shows how far the firm’s control over the market extends, market share is the direct indicator of each firm’s position in the market. Its key role is of ancient tradition, and it reflects a universal recognition in business life that market share is commonly decisive for the firm’s degree of success.
