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.

AMERICAN ECONOMIC ASSOCIATION A formal organization of professional economists that promotes economic research, organizes annual meetings and conferences, and maintains a list of publications in several economics subjects. The American Economic Association (AEA) was originally organized by a small group interested in economics at a meeting in 1888 in Saratoga, New York. However, as interest in the subject grew, it officially incorporated in 1923. Although the AEA contained only a small number of members in the beginning, today the membership is approximately 18,000. In addition, about 4,600 libraries, institutions, and firms subscribe to the quarterly publications of the AEA.

The Business About INVESTMENTI had fun that last time we wandered into Shady Valley's very own Happy-Time Gala-World Fun-Land Amusement Park, didn't you? Let's stroll through it again, just to see what adventures we might find. Okay, I admit to an ulterior motive. The Happy-Time Gala-World Fun-Land Amusement Park recently added a new ride -- the Cap'n Space Fright Whirl. If you thought the Monster Loop Death Plunge roller coaster was exciting, then you're in for a real treat with this one. My interest in the Cap'n Space Fright Whirl, however, is NOT from the standpoint of risking a recently eaten meal. On the contrary, I'm going to don my pointy-headed economist disguise and check out this mass of twisted metal and high-flying cages as a prime example of capital. In the process we might be able to gain some insight into the whys and wherefors of the thing we call investment.
