N-firm concentration ratio, N-firm concentration ratio is a common measure of market structure. This gives the combined market share of the N largest firms in the market. [ 9 ] For example, if the 5-firm concentration ratio in the United States smart phone industry is about .8, which indicates that the combined market share of the five largest ...
If the firm is a perfect competitor in all input markets, and thus the per-unit prices of all its inputs are unaffected by how much of the inputs the firm purchases, then it can be shown that at a particular level of output, the firm has economies of scale (i.e., is operating in a downward sloping region of the long-run average cost curve) if ...
Williamson sees the limit on the size of the firm as being given partly by costs of delegation (as a firm's size increases its hierarchical bureaucracy does too), and the large firm's increasing inability to replicate the high-powered incentives of the residual income of an owner-entrepreneur. This is partly because it is in the nature of a ...

In economics, industrial organization is a field that builds on the theory of the firm by examining the structure of (and, therefore, the boundaries between) firms and markets. Industrial organization adds real-world complications to the perfectly competitive model, complications such as transaction costs , [ 1 ] limited information , and ...
If the firm is a monopolist, the marginal revenue curve would have a negative slope as shown in the next graph, because it would be based on the downward-sloping market demand curve. The optimal output, shown in the graph as Q m {\displaystyle Q_{m}} , is the level of output at which marginal cost equals marginal revenue.
In practice, there are complications in observing the direct correlation between market concentration and its effect on. In collecting empirical evidence, issues have also arisen as to how innovation, a firm's control and gaps between R&D and firm size are measured. There has also been a lack of consensus.
