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).

The Revenue Curves
|
|
|
- The revenue side of the firm's production decision involves two curves:
- Demand (Average Revenue) (D = AR): The average revenue curve, which is also the demand curve, is negatively-sloped, reflecting the law of demand and the firm's minimal market control.
- Marginal Revenue (MR): The marginal revenue curve indicates the extra revenue received by the firm for producing extra units.

AVERAGE VARIABLE COST Total variable cost per unit of output, found by dividing total variable cost by the quantity of output. When compared with price (per unit revenue), average variable cost (AVC) indicates whether or not a profit-maximizing firm should shut down production in the short run. Average variable cost is one of three average cost concepts important to short-run production analysis. The other two are average total cost and average fixed cost. A related concept is marginal cost.

[What's This?]
Today, you are likely to spend a great deal of time looking for a downtown retail store seeking to buy either a half-dozen helium filled balloons or a packet of address labels large enough for addresses of both the sender and the recipient. Be on the lookout for broken fingernail clippers.
