ENERGY PRICES, AGGREGATE SUPPLY DETERMINANT: One of several specific aggregate supply determinants assumed constant when the aggregate supply curve is constructed, and that shifts the aggregate supply curve when it changes. An increase in the energy prices causes a decrease (leftward shift) of the aggregate supply curve. A decrease in the energy prices causes an increase (rightward shift) of the aggregate supply curve. Other notable aggregate supply determinants include technology, wages, and the capital stock. Energy prices fall under the resource price aggregate supply determinant.

LONG-RUN AVERAGE COST CURVE: A curve depicting the per unit cost of producing a good or service in the long run when all inputs are variable. The long-run average cost curve (usually abbreviated LRAC) can be derived in two ways. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. at different output levels. The more common method, however, is as an envelope of an infinite number of short-run average total cost curves. Such an envelope is base on identifying the point on each short-run average total cost curve that provides the lowest possible average cost for each quantity of output. The long-run average cost curve is U-shaped, reflecting economies of scale (or increasing returns to scale) when negatively-sloped and diseconomies of scale (or decreasing returns to scale) when positively sloped. The minimum point (or range) on the LRAC curve is the minimum efficient scale.

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.

[What's This?]
Today, you are likely to spend a great deal of time at a garage sale wanting to buy either a key chain with a built-in flashlight and panic button or a green and yellow striped sweater vest. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
