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.

EQUILIBRIUM, SHORT-RUN AGGREGATE MARKET The state of equilibrium that exists in the short-run aggregate market when real aggregate expenditures are equal to full-employment real production with no imbalances to induce changes in the price level or real production. The opposing forces of aggregate demand (the buyers) and short-run aggregate supply (the sellers) exactly offset each other. At the existing price level, the four macroeconomic sectors (household, business, government, and foreign) purchase all of the real production that they seek and producers sell all of the real production that they have.
