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.

EFFECTIVE DEMAND A key conceptual notion of Keynesian economics stipulating that the aggregate expenditures on real production is based on existing or actual income rather than the income that would be generated with full employment of resources. Effective demand is embodied in the aggregate expenditures line, which has a positive slope, but a slope of less than one. This concept was proposed by Thomas Robert Malthus in the early 1800s as a counter argument to Say's law found in classical economics and then found new life when John Maynard Keynes developed his theory in the 1930s.
