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.

Instability of business investment is one explanation of business cycles.- During the Great Depression, production declined by 40% and investment declined by over 90%. Did this big drop in investment cause the overall drop in production?
- Investment can trigger changes in production through the circular flow. A decrease in investment, causes a decrease in production, which reduces household income, which reduces consumption, which causes further reductions in production, income, and consumption.
- Small changes in investment can cause magnified changes in aggregate production. A $10 billion decrease in investment might cause a $50 billion decrease in GDP.
