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.

WEIGHT GAINING: An activity in which the transportation cost of the output is greater than the transportation cost of the inputs. Using the term weight to mean transportation cost, an activity is said to gain weight if the cost of moving the output to the market is greater than the cost of getting the inputs to the factory. A weight-gaining activity has a greater attraction to, and tends to locate near, the market for the output.

A graphical model used to analyze the trade between two nations based on the domestic markets for a particular good in each nation. The international market combines the excess demand (or import demand) from one country with the excess supply (or export supply) from another to illustrate how two nations undertake mutually beneficial trade. The international market model also can be used to analyze the impact of tariffs, import quotas, and export subsidies.
