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.

AGGREGATE DEMAND DECREASE, LONG-RUN AGGREGATE MARKET A shock to the long-run aggregate market caused by a decrease in aggregate demand resulting in and illustrated by a leftward shift of the aggregate demand curve. A decrease in aggregate demand in the long-run aggregate market results in an increase in the price level but no change in real production. The level of real production resulting from the aggregate demand shock is full-employment real production.
