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.

LABOR FORCE The total number of people in an economy, society, or country willing and able to exert mental and/or physical efforts in productive activities. The labor force is a more technical term for the labor resource or labor supply. It includes both employed workers and unemployed workers. An official variation of this term is civilian labor force. While labor force may or may not include military personnel, the civilian labor force explicitly excludes the military. Labor and labor resources are the theoretical terms that economists like to banter about. Labor force and civilian labor force are the terms of choice for government policy makers, data-crunchers, and others who need precise labor resource numbers.

"I learned about the strength you can get from a close family life. I learned to keep going, even in bad times. I learned not to despair, even when my world was falling apart. I learned that there are no free lunches. And I learned the value of hard work. " -- Lee Iacocca
