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.

Marginal cost of search, also termed marginal search cost, is comparable to marginal cost of short-run production analysis. Marginal cost of search increases with an increase in search effort and is represented by the marginal cost of search curve. This is one half of the efficient information search decision. The other is marginal benefit of search.
