PERFECT COMPETITION, LONG-RUN ADJUSTMENT: A perfectly competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each perfectly competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminate economic profit or economic loss. The end result of this long-run adjustment is a multi-faceted equilibrium condition that price is equal to marginal cost and average cost (both short run and long run).

NET EXPORTS LINE: The graphical depiction of the relation between net exports and national income (or gross domestic product) that plays a role in Keynesian economics and the Keynesian cross. The net exports line is derived by combining the exports line, relating exports and national income, with the imports line, relating imports and national income. Because exports are largely independent of national income and imports (which are subtracted from exports) increase with national income, the net exports line has a negative slope. The slope of the net exports line is thus the negative of the marginal propensity to import. The aggregate expenditures line used in the Keynesian cross is obtained by adding this net exports line, as well as, government purchases and net exports, to the consumption line. The government purchases line is also combined with investment expenditures for the Keynesian saving-investment model. See also | exports | imports | net exports | marginal propensity to import | foreign sector | consumption function | Keynesian economics | marginal propensity to consume | aggregate expenditures | aggregate expenditures line | Keynesian cross | government purchases line | investment line | aggregate expenditures line |

AVERAGE FACTOR COST Total factor cost per unit of factor input employed by a firm in the production of output, found by dividing total factor cost by the quantity of factor input. Average factor cost, abbreviated AFC, is generally equal to the factor price. However, using the longer term average factor cost makes it easier to see the connection to related terms, including total factor cost and marginal factor cost.

[What's This?]
Today, you are likely to spend a great deal of time touring the new suburban shopping complex seeking to buy either any book written by Stephan King or a T-shirt commemorating next Thursday. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
