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.

STRUCTURAL UNEMPLOYMENT Unemployment caused by a mismatch between workers' skills and the skills needed for available jobs. Structural unemployment essentially occurs because resources, especially labor, are configured (trained) for a given technology but the economy demands goods and services using another technology. Employers seek workers who have one type of skill and workers seeking employment have a different type of skill. This mismatch in skills, largely the result of technological progress, creates unemployment of the structural variety. Structural unemployment is one of four unemployment sources. The other three are cyclical unemployment, seasonal unemployment, and frictional unemployment. Frictional and structural unemployment are the two components of natural unemployment.
