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.

INFORMATION SEARCH The decision to seek out or produce information based on a comparison of the cost of acquiring the information and the benefit obtained from the information. Efficient information search is achieved with a equality between the marginal cost of search and the marginal benefit of search. Because the marginal cost of search is invariably greater than zero, search effort stops short of acquiring complete information.
