If only diseconomies of scale existed, then the long-run average cost-minimizing firm size would be one worker, producing the minimal possible level of output. However, economies of scale also apply, which state that large firms can have lower per-unit costs due to buying at bulk discounts (components, insurance, real estate, advertising, etc.) and can also limit competition by buying out ...
Sample size determination or estimation is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample.
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 ...
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 ...
Dunbar's number has become of interest in anthropology, evolutionary psychology, [12] statistics, and business management.For example, developers of social software are interested in it, as they need to know the size of social networks their software needs to take into account; and in the modern military, operational psychologists seek such data to support or refute policies related to ...
It compares a firm's price of output with its associated marginal cost where marginal cost pricing is the "socially optimal level" achieved in market with perfect competition. [41] Lerner (1934) believes that market power is the monopoly manufacturers' ability to raise prices above their marginal cost. [ 42 ]
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 ...
For instance, if the minimum efficient scale is small relative to the overall size of the market (demand for the good), there will be a large number of firms. The firms in this market will be likely to behave in a perfectly competitive manner due to the large number of competitors. [ 4 ]
