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.

ASYMMETRIC INFORMATION Information is not equally available to everyone. Asymmetric information results because efficient information search inevitably stops short of compete information. Some people obtain more benefits from information than others, are willing to incur higher search costs, and thus end up knowing more. Or they incur lower information search costs and have easier access to the information. In a market, sellers tend to have more information about the good than buyers. Asymmetric information gives rise to adverse selection, moral hazard, and the principal-agent problem. These problems can be lessened through signalling and screening.
