WIDGET: A fictitious good commonly used by economic instructors to demonstrate economic principles or undertake hypothetical analyses. For example, the analysis of short-run production for a firm might be demonstrated through the production of widgets. Alternatively, the law of demand might be illustrated with a table or curve comparing the price of widgets with the quantity demanded of widgets. If such a good exists, and there is no clear evidence that widgets have every existed, it is a small mechanical device, constructed of interlocking cogs, several knobs, and at least one handle. Widgets are most often used when thingamajigs and dohickies are unavailable.

DISECONOMIES OF SCALE Increasing long-run average cost that occurs as a firm increases all inputs and expands its scale of production. Diseconomies of scale result from decreasing returns to scale and are graphically illustrated by a positively-sloped long-run average cost curve. Diseconomies of scale usually occur for relatively large levels of production and overwhelm economies of scale that occurs at relatively small production levels. Together, economies of scale and diseconomies of scale create a U-shaped long-run average cost curve.
