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.

AVERAGE TOTAL COST CURVE A curve that graphically represents the relation between average total cost incurred by a firm in the short-run product of a good or service and the quantity produced. The average total cost curve is constructed to capture the relation between average total cost and the level of output, holding other variables, like technology and resource prices, constant. The average total cost curve is one of three average curves. The other two are average variable cost curve and average fixed cost curve. A related curve is the marginal cost curve.
