KINKED-DEMAND CURVE ANALYSIS: An analysis that seeks to explain rigid oligopolistic prices using the kinked-demand curve. The kinked demand curve contains two distinct segments, one for higher prices that is more elastic and one for lower prices that is less elastic. The corresponding marginal revenue curve contains a vertical segment at the existing or initial quantity. Because a profit-maximizing oligopolistic firm equates marginal cost to marginal revenue, marginal cost also can take on a range of values at the existing quantity. In other words, marginal cost can increase or decrease without inducing a profit-maximizing oligopolistic firm to change price or quantity.

CONCENTRATION RATIOS A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.
