MARGINAL PRODUCT CURVE: A curve that graphically illustrates the relation between marginal product and the quantity of the variable input, holding all other inputs fixed. This curve indicates the incremental change in output at each level of the variable input. The marginal product curve is one of three related curves used in the analysis of the short-run production of a firm. The other two are total product curve and average product curve. The marginal product curve plays in key role in the economic analysis of short-run production by a firm in large part because economists are generally obsessed with marginal changes in production.

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.

Why do we put ourselves through 12 to 20 years of oppression in the halls of academia, learning stuff of questionable value? Why? Why? WHY?
