LORENZ CURVE: In general, a diagram illustrating the degree of inequality and concentration for a group. This is accomplished by plotting the cumulative percentage of a total amount obtained by cumulative percentages of the group. A common use of the Lorenz curve is the distribution of income, in which the cumulative percentage of income is measured on the vertical axis and the cumulative percentage of the population is measured on the horizontal axis. Perfect equality is indicated by a 45-degree line (that is, 10% of the population has 10% of the income, 20% of the population has 20% of the income, etc.). The actual Lorenz curve inevitably lies below the 45-degree line. The extent that the Lorenz curve differs from the 45-degree line indicates the extent of inequality.

MARGINAL REVENUE, PERFECT COMPETITION The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a perfectly competitive firm receives for selling an extra unit of output. It is found by dividing the change in total revenue by the change in the quantity of output. Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a perfectly competitive firm equates marginal revenue and marginal cost.
