ACCELERATOR: The ratio between investment expenditures and the change in gross domestic product. This is based on the notion that business investment depends on the rate of growth of aggregate output. If the economy is expanding, in other words, then the business sector invests in more capital goods to produce the extra output needed. This accelerator effect modifies and magnifies the simply multiplier effect based on the induced consumption and the marginal propensity to consume.

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.
