KEYNESIAN EQUILIBRIUM: The state of the macroeconomy in which aggregate expenditures are equal to aggregate output. This is illustrated using the income-expenditure model, or Keynesian cross, as the intersection of the aggregate expenditures line and the 45-degree line. The aggregate expenditures line is the summation of consumption expenditures, investment expenditures, government purchases, and net exports. The 45-degree line represents all combinations in which aggregate expenditures equal aggregate output. Keynesian equilibrium is also represented by the saving-investment, or injection-leakage, model as the intersection between the injection line (investment expenditures, government purchases, and exports) and the leakage line (saving, taxes, and imports).

PRICE DISCRIMINATION: Charging different prices to different buyers for the same good. This is an age old practice for suppliers who have achieved some degree of market control, especially those with a monopoly. The reason for price discrimination, of course, is higher profit. To be a successful price discriminator you must be able to do three things--(1) have market control and be a price maker, (2) identify two or more groups that are willing to pay different prices, and (3) keep the buyers in one group from reselling the good to another group. In this way, you will be able to charge each group what they, and they alone, are willing to pay. See also | market control | monopoly | profit | perfect price discrimination | first-degree price discrimination | second-degree price discrimination | third-degree price discrimination | price maker |

U-SHAPED COST CURVES The family of short-run cost curves consisting of average total cost, average variable cost, and marginal cost, all of which have U-shapes. Each is U-shaped because it begins with relatively high but falling cost for small quantities of output, reaches a minimum value, then has rising cost at large quantities of output. Although the average fixed cost curve is not U-shaped, it is occasionally included with the other three just for sake of completeness.
